Industry and Market Data

Although we are responsible for all disclosure contained in this Annual Report on Form 10-K, in some cases we have relied on certain market and industry data obtained from third-party sources that we believe to be reliable. Market estimates are calculated by using independent industry publications in conjunction with our assumptions regarding the Sui industry and market. While we are not aware of any misstatements regarding any market, industry or similar data presented herein, such data involves risks and uncertainties and is subject to change based on various factors, including those discussed under the headings “Forward-Looking Statements” and “Item 1A. Risk Factors” in this Annual Report.

Forward-Looking Statements

This Annual Report on Form 10-K contains “forward-looking statements” with respect to the financial conditions, results of operations, plans, objectives, future performance and business of Grayscale Sui Staking ETF (the “Trust”). Statements preceded by, followed by or that include words such as “may,” “might,” “will,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “potential” or “continue,” the negative of these terms and other similar expressions are intended to identify some of the forward-looking statements. All statements (other than statements of historical fact) included in this Annual Report that address activities, events or developments that will or may occur in the future, including such matters as changes in market prices and conditions, the Trust’s operations, the plans of Grayscale Investments Sponsors, LLC (the “Sponsor”), and references to the Trust’s future success and other similar matters are forward-looking statements. These statements are only predictions. Actual events or results may differ materially from such statements. These statements are based upon certain assumptions and analyses the Sponsor made based on its perception of historical trends, current conditions and expected future developments, as well as other factors appropriate in the circumstances. Whether or not actual results and developments will conform to the Sponsor’s expectations and predictions, however, is subject to a number of risks and uncertainties, including, but not limited to, those described in “Part I, Item 1A. Risk Factors.” Forward-looking statements are made based on the Sponsor’s beliefs, estimates and opinions on the date the statements are made and neither the Trust nor the Sponsor is under a duty or undertakes an obligation to update forward-looking statements if these beliefs, estimates and opinions or other circumstances should change, other than as required by applicable laws. Investors are therefore cautioned against relying on forward-looking statements. Factors which could have a material adverse effect on the Trust’s business, financial condition or results of operations and future prospects or which could cause actual results to differ materially from the Trust’s expectations include, but are not limited to, those described in “Item 1A. Risk Factors.”

Summary of Risk Factors

Below is a summary of the principal factors that make an investment in the Shares speculative or risky. This summary does not address all of the risks that we face. Additional discussion of the risks summarized in this risk factor summary, and other risks that we face, can be found below in “Item 1A. Risk Factors.” Some of the factors that could materially and adversely affect our business include, but are not limited to, the following:

Risk Factors Related to Digital Assets

•

Extreme volatility of trading prices that many digital assets, including SUI, have experienced in recent periods and may continue to experience, could have a material adverse effect on the value of the Shares and the Shares could lose all or substantially all of their value.

•

The medium-to-long term value of the Shares is subject to a number of factors relating to the capabilities and development of blockchain technologies and to the fundamental investment characteristics of digital assets.

•

Digital assets represent a relatively new and rapidly evolving industry, and the value of the Shares depends on the acceptance of SUI.

•

Digital assets may have concentrated ownership and large sales or distributions by holders of such digital assets could have an adverse effect on the market price of such digital assets.

•

A temporary or permanent “fork” or a “clone” could adversely affect the value of the Shares.

Risk Factors Related to the Digital Asset Markets

•

Recent developments in the digital asset economy have led to extreme volatility and disruption in digital asset markets, a loss of confidence in participants of the digital asset ecosystem, significant negative publicity surrounding digital assets broadly and market-wide declines in liquidity.

•

The value of the Shares relates directly to the value of SUI held by the Trust, the value of which may be highly volatile and subject to fluctuations.

•

The largely unregulated nature and lack of transparency surrounding the operations of Digital Asset Trading Platforms may adversely affect the value of digital assets and, consequently, the value of the Shares.

•

Digital Asset Trading Platforms may be exposed to front-running and wash-trading.

•

The Index has a limited history and a failure of the Index Price could adversely affect the value of the Shares.

•

Competition from the emergence or growth of other digital assets could have a negative impact on the price of SUI and adversely affect the value of the Shares.

Risk Factors Related to the Trust and the Shares

•

The Trust relies on third-party service providers to perform certain functions essential to the affairs of the Trust and the replacement of such service providers could pose challenges to the safekeeping of the Trust’s SUI and to the operations of the Trust.

•

The liquidity of the Shares may be affected if Authorized Participants cease to perform their obligations under the Participant Agreements or the Liquidity Engager is unable to engage Liquidity Providers.

•

The Shares may trade at a price that is at, above or below the Trust’s NAV per Share as a result of the non-concurrent trading hours between NYSE Arca and the Digital Asset Trading Platform Market.

•

Any suspension or other unavailability of the Trust’s redemption program may cause the Shares to trade at a discount to the NAV per Share.

•

Shareholders may suffer a loss on their investment if the Shares trade above or below the Trust’s NAV per Share.

•

The limited ability to facilitate in-kind creations and redemptions of Shares could have adverse consequences for the Trust.

•

Extraordinary expenses, tax liabilities arising from SUI sales without distributions, indemnification obligations, intellectual property claims, and disruptions from pandemics or other disasters could adversely affect the value of the Shares.

Risk Factors Related to the Regulation of Digital Assets, the Trust and the Shares

•

A determination that SUI or any other digital asset is or involves a transaction in a “security” may adversely affect the value of SUI and the value of the Shares, and result in potentially extraordinary, nonrecurring expenses to, or termination of, the Trust.

•

Regulatory changes or actions by the U.S. Congress or any U.S. federal or state agencies may affect the value of the Shares or restrict the use of one or more digital assets, validating activity or the operation of their networks or the Digital Asset Markets in a manner that adversely affects the value of the Shares.

•

Regulatory changes or other events in foreign jurisdictions may affect the value of the Shares or restrict the use of one or more digital assets, validating activity or the operation of their networks or the Digital Asset Trading Platform Market in a manner that adversely affects the value of the Shares.

•

The Authorized Participant, the Trust or the Sponsor could be subject to regulation as a money service business or money transmitter, which could result in extraordinary expenses to the Authorized Participant, the Trust or the Sponsor and also result in decreased liquidity for the Shares.

•

Regulatory changes or interpretations could obligate the Trust or the Sponsor to register and comply with new regulations, resulting in potentially extraordinary, nonrecurring expenses to the Trust.

•

The uncertain and evolving tax treatment of the Trust, digital assets, SUI and transactions involving SUI under U.S. federal, state, and local tax laws could adversely affect the value of the Shares.

Risk Factors Related to Potential Conflicts of Interest

•

Conflicts of interest may arise among the Sponsor or its affiliates and the Trust.

•

Shareholders cannot be assured of the Sponsor’s continued services, the discontinuance of which may be detrimental to the Trust.

•

If the Custodian resigns or is removed by the Sponsor, or otherwise, without replacement, it would trigger early termination of the Trust.

iii

Risk Factors Related to Staking

•

The lack of ability to participate in any different form of Staking to the extent the Staking Condition is not satisfied, which could have adverse consequences for the Trust.

•

Staking introduces a risk of loss of SUI which could adversely affect the value of the Shares.

•

Staked SUI tokens will be inaccessible for a variable period of time, determined by a range of factors, which could result in certain liquidity risk to the Trust.

•

The Trust will be dependent on third parties to effectively execute the Trust’s Staking Arrangements.

•

The regulatory landscape surrounding Staking is uncertain.

•

Beneficial owners of Shares could incur tax liabilities without receiving corresponding distributions from the Trust.

Unless otherwise stated or the context otherwise requires, the terms “we,” “our” and “us” in this Annual Report refer to the Sponsor acting on behalf of the Trust.

Overview of the Trust and the Shares

Grayscale Sui Staking ETF (formerly known as Grayscale Sui Trust (SUI)) (the “Trust”) is a Delaware Statutory Trust that was formed on April 30, 2024, by the filing of the Certificate of Trust with the Delaware Secretary of State in accordance with the provisions of the Delaware Statutory Trust Act. The Trust’s purpose is to hold Sui tokens (“SUI”), which are digital assets that are created and transmitted through the operations of the peer-to-peer Sui Network, a decentralized network of computers that operates on cryptographic protocols.

As of December 31, 2025, the Trust holds approximately 0.08% of the SUI in circulation. The size of the Trust’s position does not itself enable the Sponsor or the Trust to participate in or otherwise influence the development of the Sui Network. As a decentralized digital asset network, the Sui Network consists of several stakeholders, including core developers of SUI, users, services, businesses, validators and other constituencies, of which the Trust is only one constituent. Furthermore, in contrast to other protocols in which token holders participate in the governance of the network, ownership of SUI confers no such rights.

On February 17, 2026, the Trust changed its name from Grayscale Sui Trust (SUI) to Grayscale Sui Staking ETF by filing a Certificate of Amendment to the Certificate of Trust with the Delaware Secretary of State. Since its inception and prior to listing its Shares on NYSE Arca, the Trust had issued common units of fractional undivided beneficial interest (“Shares”), which represent ownership in the Trust, on a periodic basis to certain “accredited investors” within the meaning of Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”) in exchange for deposits of SUI.

On September 17, 2025, the Securities and Exchange Commission (the “SEC”) approved a proposed rule change for new Rule 8.201-E (Generic) pursuant to Rule 19b-4 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) to amend NYSE Arca, Inc.’s (“NYSE Arca”) listing rules to permit the listing and trading of shares of certain commodity-based exchange-traded products that satisfy certain generic requirements (the “Generic Listing Standards”). On February 17, 2026, NYSE Arca certified its approval for listing and trading of the Shares of the Trust under the Generic Listing Standards and registration of the Shares under the Exchange Act, which began trading on NYSE Arca on February 18, 2026 (the “Uplisting Date”), following the effectiveness of the Trust’s registration statement on Form S-1, as amended (File No. 333-291974), and since then, the Trust issues shares pursuant to the registration statement on a continuous basis. The Shares are listed on NYSE Arca under the ticker symbol “GSUI.”

As a passive investment vehicle, the Trust’s investment objective is for the value of the Shares (based on SUI per Share) to reflect the value of the SUI held by the Trust, including SUI earned as Staking Consideration, determined by reference to the Index Price, less the Trust’s expenses and other liabilities. Except for any SUI earned as Staking Consideration, the Trust does not seek to generate returns beyond tracking the price of SUI. There can be no assurance that the Trust will be able to achieve its investment objective. Historically, the Trust has not met its investment objective and, prior to their uplisting to NYSE Arca on February 18, 2026, the Shares quoted on the OTCQB Best Market® (“OTCQB”) of OTC Markets Group Inc. did not reflect the value of the SUI held by the Trust, less the Trust’s expenses and other liabilities, but instead had traded at both premiums and discounts to such value, which at times were substantial, although the Sponsor has observed that the Trust has begun to meet its investment objective more closely following the uplisting of the Shares to NYSE Arca. The Trust will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective.

Until December 31, 2024, Grayscale Investments, LLC was the sponsor and administrator of the Trust. As a result of the Reorganization (as defined herein) on January 1, 2025, Grayscale Investments Sponsors, LLC (“GSIS”) and Grayscale Operating, LLC (“GSO”), consolidated subsidiaries of Digital Currency Group, Inc. (“DCG”), became Co-Sponsors of the Trust. On January 3, 2025 GSO voluntarily withdrew as a Sponsor of the Trust, and effective May 3, 2025 GSIS is the sole remaining Sponsor. Prior to May 3, 2025, all references herein to the “Sponsor” shall be deemed to include both GSIS and GSO as Sponsors unless the context otherwise requires, and on or after May 3, 2025, all references herein to the “Sponsor” shall refer only to GSIS. CSC Delaware Trust Company is the trustee of the Trust (the “Trustee”), The Bank of New York Mellon is the transfer agent (in such capacity, the “Transfer Agent”) and the administrator (in such capacity, the “Administrator”) of the Trust, Continental Stock Transfer & Trust Company is the co-transfer agent of the Trust (the “Co-Transfer Agent”), Coinbase, Inc. is the prime broker (the “Prime Broker”) of the Trust, and Coinbase Custody Trust Company, LLC is the custodian (the “Custodian”) of the Trust.

The Trust issues Shares only in one or more blocks of 10,000 Shares (a block of 10,000 Shares is called a “Basket”) to certain authorized participants (“Authorized Participants”) from time to time. The Trust creates Baskets of Shares only upon receipt of SUI and redeems Shares only by distributing SUI or proceeds from the disposition of SUI. Authorized Participants may submit orders to create or redeem Shares under one of two procedures, which are referred to as “In-Kind Orders” and “Cash Orders” in this annual report. In connection with In-Kind Orders, Authorized Participants, or their AP Designees, deposit SUI directly with the Trust or receive SUI directly from the Trust. Cash Orders are made through the participation of a Liquidity Provider (as defined herein) and facilitated by the Transfer Agent, as described in “—Description of Creation and Redemption of Shares.”

The Shares are neither interests in nor obligations of the Sponsor or the Trustee. As provided under the Trust Agreement, the Trust’s assets will not be loaned or pledged, or serve as collateral for any loan, margin, rehypothecation, or other similar activity to which the Sponsor, the Trust or any of their respective affiliates are a party.

The Sponsor maintains an internet website at etfs.grayscale.com/gsui, through which the registrant’s annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act, as amended, are made available free of charge after they have been filed or furnished to the SEC. Additional information regarding the Trust may also be found on the SEC’s EDGAR database at www.sec.gov.

The contents of the websites referred to above and any websites referred to herein are not incorporated into this filing or any other reports or documents we file with or furnish to the SEC. Further, our references to the URLs for these websites are intended to be inactive textual references only.

Investment Objective

The Trust’s investment objective is for the value of the Shares (based on SUI per Share) to reflect the value of SUI held by the Trust, including SUI earned as Staking Consideration, determined by reference to the Index Price, less the Trust’s expenses and other liabilities. Historically, the Trust has not met its investment objective and, prior to their uplisting to NYSE Arca on February 18, 2026, the Shares quoted on OTCQB did not reflect the value of the SUI held by the Trust, less the Trust’s expenses and other liabilities, but instead had traded at both premiums and discounts to such value, which at times were substantial, although the Sponsor has observed that the Trust has begun to meet its investment objective more closely following the uplisting of the Shares to NYSE Arca on February 18, 2026. In addition, the Trust commenced Staking following the uplisting of the Shares to NYSE Arca on February 18, 2026.

In the event the Shares trade at a substantial premium, investors who purchase Shares on NYSE Arca will pay substantially more for their Shares than investors who purchase Shares directly from Authorized Participants. The value of the Shares may not reflect the value of the Trust’s SUI, less the Trust’s expenses and other liabilities, for a variety of reasons, including any halting of creations or redemptions by the Trust, SUI price volatility, trading volumes on, or closures of, trading platforms where digital assets trade due to fraud, failure, security breaches or otherwise, and the non-concurrent trading hours between NYSE Arca and the global trading platform market for trading SUI. As a result, the Shares may trade at a premium over, or a discount to, the value of the Trust’s SUI, less the Trust’s expenses and other liabilities, and the Trust may be unable to meet its investment objective from time to time.

For example, from November 24, 2025 to December 31, 2025, the maximum premium of the closing price of the Shares quoted on OTCQB over the value of the Trust's NAV per Share was 38%, the average premium was 29%, the maximum discount of the closing price of the Shares quoted on OTCQB below the value of the Trust's NAV per Share was 30%, and the average discount was 11%. The closing price of the Shares, as quoted on OTCQB at 4:00 p.m., New York time, on each business day between November 24, 2025 and December 31, 2025, has been quoted at a discount on 20 days. As of December 31, 2025, the Trust's Shares were quoted on OTCQB at a discount of 3% to the Trust's NAV per Share. As of March 19, 2026, the Trust's Shares were quoted on NYSE Arca at a premium of 0.0007% to the Trust's NAV per Share. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Secondary Market Trading.”

While an investment in the Shares is not a direct investment in SUI, the Shares are designed to provide investors with a cost-effective and convenient way to gain investment exposure to SUI. A substantial direct investment in SUI may require expensive and sometimes complicated arrangements in connection with the acquisition, security and safekeeping of the SUI and may involve the payment of substantial fees to acquire such SUI from third-party facilitators through cash payments of U.S. dollars. Because the value of the Shares is correlated with the value of the SUI held by the Trust, it is important to understand the investment attributes of, and the market for, SUI.

The Trust’s SUI are carried, for financial statement purposes, at fair value, as required by the U.S. generally accepted accounting principles (“U.S. GAAP”). The Trust determines the fair value of SUI based on the price provided by the Digital Asset Market that the Trust considers its principal market as of 4:00 p.m., New York time, on the valuation date. The net asset value of the Trust determined on a U.S. GAAP basis is referred to in this Annual Report as “Principal Market NAV.” See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates—Principal Market and Fair Value Determination” for more information on the Trust’s principal market selection.

The Trust uses the Index Price to calculate its “NAV,” a non-GAAP metric, which is the aggregate value, expressed in U.S. dollars, of the Trust’s assets (other than U.S. dollars or other fiat currency), less the U.S. dollar value of the Trust’s expenses and other liabilities, calculated in the manner set forth under “—Valuation of SUI and Determination of NAV.” “NAV per Share” is calculated by dividing NAV by the number of Shares currently outstanding. NAV and NAV per Share are not measures calculated in accordance with U.S. GAAP. NAV is not intended to be a substitute for the Trust’s Principal Market NAV calculated in accordance with U.S. GAAP, and NAV per Share is not intended to be a substitute for the Trust’s Principal Market NAV per Share calculated in accordance with U.S. GAAP.

is desirable or advisable for any reason to discontinue the affairs of the Trust. For example, if the Sponsor determines that SUI is a security under the federal securities laws, whether that determination is initially made by the Sponsor itself, or because a federal court upholds an allegation that SUI is a security, the Sponsor does not intend to permit the Trust to continue holding SUI in a way that would violate the federal securities laws (and therefore would either dissolve the Trust or potentially seek to operate the Trust in a manner that complies with the federal securities laws, including the Investment Company Act of 1940, as amended (the “Investment Company Act”)). See “—Description of the Trust Agreement—Termination of the Trust” for additional discussion of the circumstances under which the Trust could be dissolved. See “Item 1A. Risk Factors—Risk Factors Related to the Trust and the Shares—A determination that SUI or any other digital asset is or involves a transaction in a “security” may adversely affect the value of SUI and the value of the Shares, and result in potentially extraordinary, nonrecurring expenses to, or termination of, the Trust.”

Characteristics of the Shares

The Shares are intended to offer investors an opportunity to gain exposure to digital assets through an investment in securities. As of December 31, 2025, each Share represented approximately 14.4785 SUI. The logistics of accepting, transferring and safekeeping of SUI are dealt with by the Sponsor and Custodian, and the related expenses are built into the value of the Shares. Therefore, shareholders do not have additional tasks or costs over and above those generally associated with investing in any other privately placed security.

The Shares have certain other key characteristics, including the following:

•

Easily Accessible and Relatively Cost Efficient. Investors in the Shares can also directly access the Digital Asset Markets. The Sponsor believes that investors will be able to more effectively implement strategic and tactical asset allocation strategies that use SUI by using the Shares instead of directly purchasing and holding SUI, and for many investors, transaction costs related to the Shares will be lower than those associated with the direct purchase, storage and safekeeping of SUI.

•

Market-Traded and Transparent. The Shares are listed on NYSE Arca as of February 18, 2026. The Sponsor believes the quotation of the Shares on NYSE Arca provides investors with an efficient means to implement various investment strategies. The Trust will not hold or employ any derivative securities. Furthermore, the value of the Trust’s assets will be reported each day on etfs.grayscale.com/gsui.

•

Minimal Credit Risk. The Shares represent an interest in actual SUI owned by the Trust. The Trust’s SUI are not subject to borrowing arrangements with third parties and are subject to counterparty and minimal credit risk with respect to the Custodian. This contrasts with the other financial products such as CoinShares exchange-traded notes, TeraExchange swaps and SUI futures and options traded on the Chicago Mercantile Exchange (“CME”) and the Intercontinental Exchange (“ICE”) through which investors gain exposure to digital assets through the use of derivatives that are subject to counterparty and credit risks.

•

Safekeeping System. The Custodian has been appointed to control and secure the SUI for the Trust using offline storage, or “cold storage”, mechanisms to secure the Trust’s private key “shards”. The hardware, software, administration and continued technological development that are used by the Custodian may not be available or cost-effective for many investors.

The Trust differentiates itself from many competing digital asset financial vehicles in the following ways:

•

Custodian. The Custodian that holds the private key shards associated with the Trust’s SUI is Coinbase Custody Trust Company, LLC. Other digital asset financial vehicles that use cold storage may not use a custodian to hold their private keys.

•

Cold Storage of Private Keys. The private key shards associated with the Trust’s SUI are kept in cold storage, which means that the Trust’s SUI are disconnected and/or deleted entirely from the internet. See “—Custody of the Trust’s SUI” for more information relating to the storage and retrieval of the Trust’s private keys to and from cold storage. Other digital asset financial vehicles may not utilize cold storage or may utilize less effective cold storage-related hardware and security protocols.

•

Location of Private Vaults. Private key shards associated with the Trust’s SUI are distributed geographically by the Custodian in secure vaults around the world, including in the United States. The locations of the secure vaults may change regularly and are kept confidential by the Custodian for security purposes.

•

Enhanced Security. Transfers from the Trust’s Vault Balance require certain security procedures, including but not limited to, multiple encrypted private key shards, usernames, passwords and 2-step verification. Multiple private key shards held by the Custodian must be combined to reconstitute the private key to sign any transaction in order to transfer the Trust’s SUI. Private key shards are distributed geographically in secure vaults around the world, including in the United States. As a result, if any one secure vault is ever compromised, this event will have no impact on the ability of the Trust to access its assets, other than a possible delay in operations, while one or more of the other secure vaults is used instead. These security procedures are intended to remove single points of failure in the protection of the Trust’s SUI.

•

Custodian Inspections. The Custodian has agreed to allow the Trust and the Sponsor to take such steps as necessary to verify that satisfactory internal control systems and procedures are in place.

•

Directly Held SUI. The Trust directly owns actual SUI held through the Custodian. This may differ from other digital asset financial vehicles that provide SUI exposure through other means, such as the use of financial or derivative instruments.

•

Sponsor’s Fee. The Sponsor’s Fee is a competitive factor that may influence the value of the Shares.

Activities of the Trust

The activities of the Trust are limited to (i) issuing Baskets in exchange for SUI transferred to the Trust as consideration in connection with the creations, (ii) transferring or selling SUI as necessary to cover the Sponsor’s Fee, the Sponsor’s Staking Fee and/or any Additional Trust Expenses, (iii) transferring SUI in exchange for Baskets surrendered for redemption, (iv) causing the Sponsor to sell SUI on the termination of the Trust, (v) making distributions of Incidental Rights and/or IR Virtual Currency or cash from the sale thereof (subject to NYSE Arca obtaining regulatory approval from the SEC), as described in “—Incidental Rights and IR Virtual Currency” below, (vi) engaging in any form of Staking, but only if (and, then, only to the extent that) the Staking Condition has been satisfied with respect thereto, (vii) receiving Staking Consideration and, after payment of the Sponsor’s Staking Fee therefrom, making distributions of Staking Consideration received by the Trust (or cash from the sale thereof), and (viii) engaging in all administrative and security procedures necessary to accomplish such activities in accordance with the provisions of the Trust Agreement, the Prime Broker Agreement, the Index License Agreement and the Participant Agreements.

The Trust may engage in any lawful activity necessary or desirable in order to facilitate shareholders’ access to Incidental Rights or IR Virtual Currency (subject to NYSE Arca obtaining regulatory approval from the SEC), provided that such activities do not conflict with the terms of the Trust Agreement. See “—Incidental Rights and IR Virtual Currency” for more information. The Trust will not be actively managed. It will not engage in any activities designed to obtain a profit from, or to ameliorate losses caused by, changes in the market prices of SUI.

Staking

Staking on the Sui Network refers to using SUI, or permitting SUI to be used through an agent or otherwise, in the Sui Network’s proof-of-stake validation protocol, in exchange for the receipt of staking rewards paid in-kind (“Staking”). The Trust Agreement provides that the Trust may engage in Staking, but only if (and, then, only to the extent that) the Staking Condition has been satisfied. On February 18, 2026, the Staking Condition was satisfied with respect to the form of Staking described in this Annual Report, and on that date the Trust commenced Staking pursuant to the Staking Arrangements described below. The Sponsor may from time-to-time modify the form of Staking in which the Trust engages, but only if (and, then, only to the extent that) the Staking Condition has been satisfied with respect to any such modified form of Staking, and subject to compliance with any additional requirements that may arise in connection with satisfaction of the Staking Condition with respect thereto.

Staking Arrangements and Provider-Facilitated Staking Model

The Sponsor has caused, and from time to time may cause, the Trust to enter into written arrangements (the “Staking Arrangements”) with the Custodian and one or more third party staking providers (each, a “Staking Provider”), which may be affiliates of the Custodian or other trusted institutional validators, to stake the Trust’s SUI to a Staking Provider operating validator software and associated hardware (“Provider-Facilitated Staking”). The Sponsor anticipates that the Trust’s SUI is and will be staked exclusively by means of Provider-Facilitated Staking.

Under the Staking Arrangements, the Trust is permitted to accept only Staking Consideration received in the form of SUI, and is not permitted to accept any Other Staking Consideration in the form of other digital assets. Neither the Trust, nor the Sponsor on behalf of the Trust, has the ability under the Staking Arrangements to take advantage of any variations in the market to improve the investments of shareholders, including with respect to variations based on the value of SUI or the amount of Staking Consideration received as staking rewards. As a whole, the Staking Arrangements permit the Trust to retain ownership of its SUI at all times for U.S. federal income tax purposes while simultaneously protecting and conserving the Trust Estate by mitigating the risk that another party or group could control a majority of the Sui Network and engage in transactions that could reduce the Trust Estate’s value.

A Staking Provider must meet certain requirements in order to be selected to participate in the Provider-Facilitated Staking model contemplated by the Staking Arrangements. For example, each Staking Provider is required to be unrelated to both the Trust and the Sponsor. Under the Staking Arrangements, the Staking Provider bears all of its own expenses (including those on account of its validation activities).

The Staking Provider is the node operator and is obligated to operate the validator through which the Trust’s SUI is staked to ensure that validation occurs. The Trust’s SUI is currently staked from the Trust’s wallets administered by the Custodian, and the Staking Provider performs any related validation activities. The Trust retains control of its staked SUI because the SUI Network does not permit the Staking Provider to transfer staked SUI to any wallet other than as designated by the Sponsor. Because the Trust's staked SUI cannot, pursuant to the Sui Network protocol, be transferred other than as directed by the Sponsor, the Trust's SUI is not deemed commingled with the SUI of any other SUI holder in connection with Staking, such as the Staking Provider or others who stake to the Staking Provider, even if the Staking Provider is in receipt of other SUI holders' validation rights. In particular, the Staking Provider is not able to transfer unstaked SUI or Staking Consideration to another address on the Sui Network. The Trust does not itself undertake any validation activities, and the Sponsor is not required to perform any services. Moreover, the Sponsor is not required to make any decisions or take any actions, other than (i) selecting the Staking Provider(s) and entering into the corresponding Staking Arrangement(s), and (ii) determining, from time to time, what portion of the Trust’s SUI to stake and un-stake, and informing the Staking Provider(s) of those determinations.

The Sponsor currently engages in and anticipates that it will continue to engage in staking with respect to all of the Trust’s SUI at all times, except (i) as necessary to pay the Sponsor’s Fee and the Sponsor’s Staking Fee, (ii) as necessary to pay any additional Trust expenses, (iii) as necessary to satisfy existing and reasonably foreseen potential redemption requests as determined by the Sponsor, (iv) as necessary to reduce the SUI obtained by the Trust as Staking Consideration to cash for distribution at regular intervals, (v) as necessary to reduce the SUI obtained by the Trust as Native Staking Consideration to cash in connection with the Trust's liquidation, (vi) as necessary to take protective actions in respect of vulnerabilities in the source code or cryptography underlying the Sui Network and/or its proof-of-stake protocol, its staking smart contracts or its validator client software, (vii) if the Custodian discontinues its arrangements with the Trust and such discontinuance affects the Trust's SUI, for so long as is reasonably necessary to re-establish those arrangements or to establish similar arrangements with other parties, (viii) if the Custodian discontinues its arrangements with the Staking Provider and such discontinuance affects the Trust's SUI, for so long as is reasonably necessary to re-establish those arrangements or to establish similar arrangements with other parties, (ix) in the event of a change in applicable law or regulation, (x) as necessary to maintain a Liquidity Sleeve (as defined herein), (xi) as necessary pursuant to a “contingent liquidity arrangement” within the meaning of Section 6.02(12) of IRS Revenue Procedure 2025-31 or (xii) in accordance with any other exception that is expressly contemplated by an opinion, ruling or tax guidance that satisfies the Staking Condition. All SUI received by the Trust in connection with the creation of new Shares, or as Staking Consideration, would also be staked upon receipt by the Trust, unless one or more of the exceptions described in clauses (i)-(xii) above applies. Under the Trust Agreement, the Trust's Staking Arrangements also must satisfy certain other requirements derived from IRS Revenue Procedure 2025-31. Moreover, any staked SUI which must be un-staked in order to fulfill a distribution in connection with a redemption (to the extent such distribution cannot be fulfilled utilizing the portion of the Trust’s SUI that has not been staked, or through another mechanism to manage liquidity in connection with Redemption Orders contemplated by an opinion of a Tax Advisor, a Tax Ruling or Tax Guidance that satisfies the Staking Condition) will be un-staked only after the redemption request is approved by the Trust, the Sponsor executes an un-stake or withdrawal transaction through the Custodian, and such transaction is processed by the Sui Network. The Staking Provider is not able to transfer unstaked SUI or Staking Consideration to another address on the Sui Network.

The Sponsor has satisfied the Staking Condition with respect to certain liquidity procedures, which it believes will ensure that it will satisfy existing and reasonably foreseen redemption requests. Specifically, the Sponsor intends to maintain a portion of unstaked SUI in the Trust (the “Liquidity Sleeve”). Because the SUI in the Liquidity Sleeve is freely transferable, there is no timing mismatch between settlement of Shares in primary market redemptions and the SUI transfer time. The percentage of the Trust’s SUI comprising the Liquidity Sleeve will be dynamic and subject to adjustment based on anticipated primary and secondary market activity of the Shares and the SUI unstaking process. The Sponsor generally seeks to stake as much of the Trust’s SUI as is practicable (i.e., up to 100%) at all times, with the remainder of the Trust’s SUI remaining unstaked in order to address the various exceptions and other considerations described herein. The percentage of the Trust’s SUI that is staked each day is reported the following day at 4:00 p.m., New York time, on etfs.grayscale.com/gsui. In the future and subject to the satisfaction of the Staking Condition thereto, the Sponsor, on behalf of the Trust, may be able to enter into other financing arrangements or implement other mechanisms to manage SUI liquidity constraints. For example, in the future, the Sponsor may arrange for the Trust to enter into redemption orders involving the delivery of SUI to a Liquidity Provider on a delayed basis (i.e., when the appropriate number of the Trust’s SUI are or become freely transferable), after the Liquidity Provider has delivered cash to the Trust to settle the redemption order. Under a delayed delivery order, the Variable Fee payable by an Authorized Participant would be adjusted, based on the estimated length of time to SUI delivery, to compensate the Liquidity Provider for agreeing to accept settlement on a delayed basis. No further adjustment to the Variable Fee would be made, and the Trust would not be required to further compensate the Liquidity Provider (or be entitled to compensation from the Liquidity Provider) if the actual date of SUI delivery differed from the estimated delivery date. It is also possible that, in connection with future redemption orders, the Sponsor may make arrangements for the Trust to obtain liquid SUI from the Custodian or another institutional liquidity provider in exchange for the Trust’s present or future delivery of a similar number of SUI tokens, although the details of any such future arrangement are not presently known. These and other liquidity risk policies and procedures are intended to be consistent with NYSE Arca’s generic listing standards. However, there can be no assurance that such arrangements would be available as intended or provide sufficient liquidity to satisfy redemption requests.

Under the Staking Arrangements, any Staking Consideration earned accrues in accordance with the Sui Network’s rewards distribution mechanism to the Trust’s wallets administered by the Custodian. Periodically, the Trust may either (i) distribute SUI received as Staking Consideration to the Trust’s beneficiaries (likely using a liquidating agent), (ii) sell that SUI for cash and distribute the proceeds to the Trust’s beneficiaries, (iii) retain the SUI in the Trust, (iv) pay a portion of the Staking Consideration to the Sponsor (the “Sponsor's Staking Fee”) as consideration for its facilitation of the Staking Arrangements or (v) a combination of the foregoing, in the Sponsor’s sole discretion. The Sponsor has implemented a staking policy with respect to the Trust, which describes the frequency of, and conditions under which the Trust will make such distributions, if any, to the Trust’s beneficiaries. The Sponsor has made such staking policy available to shareholders on the Sponsor’s website. Subject to any slashing risk, the Trust (through the Custodian) will maintain control and remain the record and beneficial owner of the staked tokens at all times, and the tokens will remain associated with the Trust’s wallet.

As of February 18, 2026, and pursuant to the Staking Arrangements, the Custodian and the Staking Provider became entitled to receive a portion of the gross Staking Consideration generated under the Staking Arrangements, reflecting the Custodian’s fee and the Staking Provider’s share of such Staking Consideration, with the remainder received by the Trust. The allocation of gross Staking Consideration between the Custodian and the Staking Provider reflects an arm’s length allocation that is independent of the expenses of both the Staking Provider and Custodian, and may be stated as a percentage of the gross Staking Consideration. In addition, pursuant to the Trust Agreement and as consideration for the Sponsor’s facilitation of Staking, the Sponsor is permitted to receive a fee equal to a portion of the Staking Consideration, payable in SUI, which accrues daily in U.S. dollars in an amount calculated as a per annum percentage of any Staking Consideration received by the Trust, as may be directed by the Sponsor in its sole discretion. The Sponsor’s Staking Fee is payable to the Sponsor daily in arrears. Effective February 18, 2026, the Sponsor’s Staking Fee, the Custodian’s fee and the Staking Provider’s share of the Staking Consideration comprise an aggregate of 23% of the gross Staking Consideration generated under the Staking Arrangements. The Trust receives and retains the remainder of such gross Staking Consideration.

From time to time, the Trust may distribute SUI (or cash from the sale of SUI) received as Staking Consideration to the Trust’s shareholders. The Sponsor has implemented a staking policy with respect to the Trust, which describes the frequency of, and conditions under which the Trust will make such distributions, if any, to the Trust’s beneficiaries, which is available to shareholders on the Sponsor’s website.

The Staking Arrangements are based on market terms, consistent with those typically offered by leading digital asset firms that offer staking functionality. However, the Trust has and will continue to negotiate certain provisions as necessary or helpful to preserve the Trust’s status as a grantor trust and the security of the Trust’s SUI, as well as to address governmental, policy or regulatory concerns. For example, unlike certain digital asset firms that offer staking functionality through which one’s SUI is pooled with that of others (including, potentially, the Staking Provider in its general staking offerings), the Staking Arrangements do not permit the Trust’s SUI to be pooled with that of other SUI holders, including the Staking Provider or others that stake to the Staking Provider, as described above. In addition, the portion of staking rewards to be received by the Staking Provider is an agreed percentage of block rewards and transaction fees generated by the validating activities, unlike certain alternative staking arrangements under which a staking provider may be compensated as an agreed percentage of SUI staked.

The Trust has no right to direct the Staking Provider in the conduct of validation activities, except to stake, un-stake and withdraw its staked SUI pursuant to instructions delivered to the Custodian, and does not and will not bear any expenses incurred by the Staking Provider in conducting those activities. In particular, the amount of any Staking Consideration that the Trust receives is not and will not be determined with reference to any expenses incurred by the Custodian or the Staking Provider. The Staking Arrangements do not include any obligation of the Trust to continue staking its SUI, or for the Custodian or the Staking Provider to continue the Staking Arrangements, other than to the extent the Trust’s SUI cannot immediately be un-staked due to requirements of the Sui protocol. There may also be instances where the Staking Provider may pause or terminate its validation activities due to its own independent assessment of the vulnerabilities of the Sui Network which would result in the Trust’s SUI not being staked for a period of time. The Sponsor anticipates that the Sui protocol and the Staking Arrangements will permit withdrawal of staked SUI at regular intervals. The Sponsor believes that market practice for Provider-Facilitated Staking arrangements has largely become standardized, with little variation in terms, and therefore, the Sponsor anticipates that the Staking Arrangements generally align with the current practice of Staking Providers’ arrangements with other similarly situated third parties, subject to the negotiation of certain bespoke terms outlined above. Accordingly, and because transitioning to a new Staking Provider would involve friction costs, the Sponsor does not expect the Trust to change Staking Providers frequently, if at all. In addition, while the Trust may enter into Staking Arrangements with multiple Staking Providers, the Sponsor anticipates that any such arrangements would be substantively identical in all material respects to the Staking Arrangements described herein, including, for the avoidance of doubt, the bespoke terms of the Staking Arrangements outlined above. Any material deviation from the Staking Arrangements as described herein would be disclosed in the Trust’s subsequent filings with the Commission.

The Staking Arrangements have not and will not involve a disposition of the Trust’s SUI unless the Staking Provider commits a slash-worthy offense. Currently on the Sui Network, slashing generally operates by social consensus, rather than being automatically

applied by the protocol’s code. The Sui community generally aspires to slash 100% of staked assets in cases where a Sui node is maliciously trying to violate safety rules and 0% during routine operations. As a result, there is currently no automatic slashing in the Sui Network. Rather, for regular consensus, after a safety violation, the Sui Network will halt. The validators will analyze the data prior to the halt to determine who was responsible and propose that the stake of the malicious actors responsible for the safety violation should be slashed after restart, typically 100% of their stake. Future protocol upgrades may include the implementation of automated slashing mechanisms, where penalties would be triggered and enforced directly by the network code without requiring social coordination. As of the date of this Annual Report, there have been no slashing events on the Sui Network. In light of the mechanical and standardized nature of validation activities, the Sponsor does not anticipate that the Staking Provider, which is expected to be an institution of recognized and trusted standing in the digital asset marketplace, with whom the Sponsor has had extensive prior interaction, will commit any slash-worthy offenses in the conduct of the Provider-Facilitated Staking activities. The Sponsor has the right to direct the Custodian to cease staking the Trust’s SUI with the Staking Provider at any time, subject to the extent the Trust’s SUI cannot immediately be un-staked due to technical considerations, and the Sponsor expects that notice of any slashing event will be timely and permit the Sponsor to halt the staking of the Trust’s SUI, thereby mitigating the risk of permanent loss of the Trust’s SUI without replacement.

Security and Controls

The Trust’s Custodian has multiple layers of security protocols intended to protect the Trust’s assets from unauthorized access or transfer, which remain in place when the Trust’s SUI is staked.

The Trust’s SUI is staked from the Trust’s wallets and is not transferred to any other wallet to be staked. The Sui protocol limits the activities of the Staking Provider to executing only those activities specified by the protocol, such as staking, un-staking and performing validation activities and does not enable the Staking Provider to unilaterally transfer staked assets to any wallet not specified by the Sponsor. Accordingly, the Staking Provider does not have any powers to move the Trust’s staked SUI other than to stake or un-stake SUI at the direction of the Sponsor. In particular, the Staking Provider is not authorized to leverage or rehypothecate the Trust’s SUI tokens. The Staking Provider is also not able to change the designated wallet addresses on the Sui Network to which staked SUI is to be withdrawn or to which Staking Consideration shall be sent.

In addition, the Staking Arrangements do not alter the Trust’s custody environment or security procedures. The controls currently in place between the Sponsor and the Custodian also govern the activities related to staking and un-staking SUI, as outlined in the Staking Arrangements.

The foregoing description of the Staking Arrangements does not purport to be complete and is qualified in its entirety by reference to the full text of the staking addendum to the Prime Broker Agreement between the Trust and the Custodian, a copy of which is attached as an exhibit hereto and incorporated herein by reference.

Incidental Rights and IR Virtual Currency

The Sponsor has notified the Prime Broker, the Custodian and Coinbase Credit, Inc. (“Coinbase Credit”), on behalf of the Trust (such notice, the “Pre-Creation/Redemption Abandonment Notices”) that the Trust will abandon, irrevocably and for no direct or indirect consideration, effective immediately prior to each time at which the Trust creates or redeems Shares (each such time, a “Creation Time” or “Redemption Time”, respectively), all Incidental Rights and IR Virtual Currency to which it would otherwise be entitled as of such time. An abandonment made pursuant to the Pre-Creation/Redemption Abandonment Notices is referred to herein as a “Pre-Creation/Redemption Abandonment.” Pursuant to the Pre-Creation/Redemption Abandonment Notices, a Pre-Creation/Redemption Abandonment would not apply to any Incidental Right or IR Virtual Currency if (i) the Trust has taken, or is taking at such time, an “Affirmative Action” to acquire or abandon such Incidental Right or IR Virtual Currency at any time prior to the relevant Creation Time or Redemption Time or (ii) such Incidental Right or IR Virtual Currency has been subject to a previous Pre-Creation/Redemption Abandonment. An “Affirmative Action” refers to a written notification from the Sponsor to the Prime Broker, the Custodian or Coinbase Credit of the Trust’s intention (i) to acquire and/or retain an Incidental Right and/or IR Virtual Currency or (ii) to abandon, with effect prior to the relevant Creation Time or Redemption Time, an Incidental Right and/or IR Virtual Currency.

As a result of the Pre-Creation/Redemption Abandonment Notices, the Trust generally has abandoned, prior to each relevant Creation Time or Redemption Time, any Incidental Right or IR Virtual Currency that it may have had any right to receive at such time. The Trust has no right to receive any Incidental Right or IR Virtual Currency abandoned pursuant to either the Pre-Creation/Redemption Abandonment Notices or Affirmative Actions. Furthermore, the Prime Broker, the Custodian and Coinbase Credit has/have no authority, pursuant to the Prime Broker Agreement or otherwise, to exercise, obtain or hold, as the case may be, any such abandoned Incidental Right or IR Virtual Currency on behalf of the Trust or to transfer any such abandoned Incidental Right or IR Virtual Currency to the Trust if the Trust terminates its custodial arrangement with the Prime Broker, the Custodian and Coinbase Credit. In addition, the Sponsor has committed to cause the Trust not to take any Affirmative Action to acquire any Incidental Right or IR Virtual Currency and, therefore, irrevocably abandon any Incidental Right and IR Virtual Currency to which the Trust may become entitled in the future.

Because the Sponsor has committed to causing the Trust to irrevocably abandon all Incidental Rights and IR Virtual Currency to which the Trust otherwise would become entitled in the future, and causing the Trust not to take any Affirmative Actions, the Trust will not receive any direct or indirect consideration for the Incidental Rights or IR Virtual Currency and thus the value of the Shares will not reflect the value of the Incidental Rights or IR Virtual Currency. In addition, in the event the Sponsor seeks to change the Trust’s policy with respect to Incidental Rights or IR Virtual Currency, an application would need to be filed with the SEC by NYSE Arca seeking approval to amend its listing rules to permit the Trust to distribute the Incidental Rights or IR Virtual Currency in-kind to an agent of the shareholders for resale by such agent. However, there can be no assurance as to whether or when the Sponsor would make such a decision, or when NYSE Arca will seek or obtain this approval, if at all. See “Item 1A. Risk Factors—Risk Factors Related to the Trust and the Shares—Shareholders will not receive the benefits of any forks or airdrops.”

The Sponsor has controls in place to monitor for material hard forks or airdrops. The Sponsor will notify investors of any material change to its policy with respect to Incidental Rights and IR Virtual Currency by filing a current report on Form 8-K.

Secondary Market Trading

While the Trust’s investment objective is for the value of the Shares (based on SUI per Share) to reflect the value of SUI held by the Trust, including SUI earned as Staking Consideration, determined by reference to the Index Price, less the Trust’s expenses and other liabilities, the Shares may trade in the Secondary Market on NYSE Arca (or on another Secondary Market in the future) at prices that are lower or higher than the NAV per Share. The amount of the discount or premium in the trading price relative to the NAV per Share may be influenced by non-concurrent trading hours and liquidity between NYSE Arca and larger Digital Asset Trading Platforms. While the Shares are listed and trade on NYSE Arca from 4:00 a.m. until 8:00 p.m., New York time, liquidity in the Digital Asset Markets may fluctuate depending upon the volume and availability of larger Digital Asset Trading Platforms. As a result, during periods in which Digital Asset Market liquidity is limited or a major Digital Asset Trading Platform is off-line, trading spreads, and the resulting premium or discount, on the Shares may widen.

Overview of the Sui Industry and Market

SUI is a digital asset that is created and transmitted through the operations of the peer-to-peer Sui Network, a decentralized network of computers that operates on cryptographic protocols. No single entity owns or operates the Sui Network, the infrastructure of which is collectively maintained by a decentralized user base. The Sui Network allows people to exchange tokens of value, called SUI, which are recorded on a public transaction ledger known as a blockchain. SUI can be used to pay for goods and services, including computational power on the Sui Network, or it can be converted to fiat currencies, such as the U.S. dollar, at rates determined on Digital Asset Trading Platforms or in individual end-user-to-end-user transactions under a barter system. Furthermore, the Sui Network was designed to allow users to write and implement smart contracts—that is, general-purpose code that executes redundantly across the network and can instruct the transmission of information and value based on a sophisticated set of logical conditions. Using smart contracts, users can create markets, store registries of debts or promises, represent the ownership of property, move funds in accordance with conditional instructions and create digital assets other than SUI on the Sui Network. Smart contract operations are executed on the Sui Network in exchange for payment of SUI. The Sui Network is one of a number of projects intended to expand blockchain use beyond just a peer-to-peer money system.

The Sui Network employs a proof-of-stake model to incentivize SUI holders to validate transactions. Unlike proof-of-work, in which miners expend computational resources to compete to validate transactions and are rewarded coins in proportion to the amount of computational resources expended, in delegated proof-of-stake, validators risk or “stake” coins to participate in transaction validation and are rewarded coins in proportion to the amount of coins staked. Any malicious activity, such as disagreeing with the eventual consensus or otherwise violating protocol rules, results in the forfeiture or “slashing” of a potential rewards that court have been earned from such staking. Proof-of-stake is viewed as more energy efficient and scalable than proof-of-work and is sometimes referred to as “virtual mining”.

To achieve consensus among validators, the network historically used a dual-layer design consisting of “Narwhal,” a data-availability layer, and “Bullshark,” a consensus protocol. However, in July 2024, the Sui Network introduced the “Mysticeti” consensus mechanism to replace Bullshark, improving transaction latency and throughput while continuing to use Narwhal for data dissemination. This configuration enables the Sui Network to verify and execute many transactions in parallel, rather than sequentially like in prominent blockchains like Bitcoin and Ethereum.

Sui was initially conceived in 2021 by Evan Cheng, Adeniyi Abiodun, Sam Blackshear, George Danezis, and Kostas Chalkias to continue research initially performed while the group was employed by Meta Platforms, Inc., in which they collaborated on a digital asset project called Diem (formerly known as Libra). Mysten Labs Inc. (“Mysten”), a for-profit software company which contributes to the development of the Sui Network, formed as an outgrowth of the Diem project. The Sui Foundation is an independent nonprofit entity that supports research and development of open-source technology related to Sui.

Although Mysten and the Sui Foundation continue to exert significant influence over the direction of the development of SUI, the Sui Network is believed to be decentralized and does not require governmental authorities or financial institution intermediaries to create, transmit or determine the value of SUI.

Sui Foundation Investment

On February 17, 2026, the Trust entered into the Sui Foundation Subscription Agreement, pursuant to which the Sui Foundation acquired Shares of the Trust in a private offering for an aggregate purchase price of approximately 20,000,000 SUI tokens (the “Sui Foundation Contribution”).

The Shares acquired by the Sui Foundation constitute restricted securities, and their resale is subject to limitations under federal securities laws. In addition, the Sui Foundation is expected to agree that, for a period of one year following the Sui Foundation Contribution (the “Lock-up Period”), the Sui Foundation shall not, without the prior written consent of the Sponsor, sell, transfer, assign, pledge, hypothecate or otherwise dispose of any of the Shares it holds, nor would the Sui Foundation seek to have the Trust or the Sponsor redeem its Shares during the Lock-up Period. Furthermore, the Sui Foundation is not an authorized participant and, accordingly, is not eligible to present a redemption basket to the Trust for redemption.

Smart Contracts and Development on the Sui Network

Smart contracts are programs that run on a blockchain that can execute automatically when certain conditions are met. Smart contracts facilitate the exchange of anything representative of value, such as money, information, property, or voting rights. Using smart contracts, users can send or receive digital assets, create markets, store registries of debts or promises, represent ownership of property or a company, move funds in accordance with conditional instructions and create new digital assets. Smart contracts on the Sui Network are written in the programming language “Sui Move,” unlike smart contracts on the Ethereum Network that are written in Solidity.

Development on the Sui Network involves building more complex tools on top of smart contracts, such as decentralized apps (“DApps”); organizations that are autonomous, known as decentralized autonomous organizations (“DAOs”); and entirely new decentralized networks. For example, a company that distributes charitable donations on behalf of users could hold donated funds in smart contracts that are paid to charities only if the charity satisfies certain pre-defined conditions.

In total, as of December 31, 2025, more than 100 DApps are currently built on the Sui Network, including DApps in the collectible non-fungible token, gaming, music streaming, and decentralized finance categories.

Additionally, the Sui Network has been used for decentralized finance (“DeFi”), or open finance platforms, which seek to democratize access to financial services, such as borrowing, lending, custody, trading, derivatives and insurance, by removing third-party intermediaries. DeFi can allow users to lend and earn interest on their digital assets, exchange one digital asset for another and create derivative digital assets such as stablecoins, which are digital assets pegged to a reserve asset such as fiat currency. As of December 31, 2025, approximately $914.9 million was being used as collateral on DeFi platforms using the Sui Network.

In addition, the Sui Network and other smart contract platforms have been used for creating non-fungible tokens, or NFTs. Unlike digital assets native to smart contract platforms which are fungible and enable the payment of fees for smart contract execution, NFTs allow for digital ownership of assets that convey certain rights to other digital or real world assets. This new paradigm allows users to own rights to other assets through NFTs, which enable users to trade them with others on the Sui Network. For example, an NFT may convey rights to a digital asset that exists in an online game or a DApp, and users can trade their NFT in the DApp or game, and carry them to other digital experiences, creating an entirely new free-market internet-native economy that can be monetized in the physical world.

Overview of the Sui Network’s Operations

In order to own, transfer or use SUI directly on the Sui Network (as opposed to through an intermediary, such as a custodian), a person generally must have internet access to connect to the Sui Network. SUI transactions may be made directly between end-users without the need for a third-party intermediary. To prevent the possibility of double-spending SUI, a user must notify the Sui Network of the transaction by broadcasting the transaction data to its network peers. The Sui Network provides confirmation against double-spending by memorializing every transaction on its ledger, which is publicly accessible and transparent. This memorialization and verification against double-spending is accomplished through the Sui Network validation process, which adds data, including recent transaction information, to the Sui Network.

Summary of a SUI Transaction

Prior to engaging in SUI transactions directly on the Sui Network, a user generally must first install on its computer or mobile

device a Sui Network software program that will allow the user to generate a private and public key pair associated with an address on the Sui Network. The Sui Network software program and the SUI address also enable the user to connect to the Sui Network and transfer SUI to, and receive SUI from, other users.

Each Sui Network address, or wallet, is associated with a unique “public key” and “private key” pair. To receive SUI, the SUI recipient must provide its public key to the party initiating the transfer. This activity is analogous to a recipient for a transaction in U.S. dollars providing a routing address in wire instructions to the payor so that cash may be wired to the recipient’s account. The payor approves the transfer to the address provided by the recipient by “signing” a transaction that consists of the recipient’s public key with the private key of the address from where the payor is transferring the SUI. The recipient, however, does not make public or provide to the sender its related private key.

Neither the recipient nor the sender reveal their private keys in a transaction, because the private key authorizes transfer of the funds in that address to other users. Therefore, if a user loses his or her private key, the user may permanently lose access to the SUI contained in the associated address. Likewise, SUI is irretrievably lost if the private key associated with them is deleted and no backup has been made. When sending SUI, a user’s Sui Network software program must validate the transaction with the associated private key. In addition, since every computation on the Sui Network requires processing power, there is a transaction fee involved with the transfer that is paid by the payor. The resulting digitally validated transaction is sent by the user’s Sui Network software program to the Sui Network validators to allow transaction confirmation.

Sui Network validators record and confirm transactions when they validate and add information to the Sui Blockchain. When a validator validates transactions, it contributes to the formation of certified data structures—sometimes referred to as blocks—which include data relating to (i) the verification of newly submitted and accepted transactions and (ii) references necessary to maintain the continuity of prior transaction records. Validators become aware of outstanding, unrecorded transactions through the data packet transmission and distribution mechanisms discussed above.

Some SUI transactions are conducted “off-blockchain” and are therefore not recorded in the Sui Blockchain. These “off-blockchain transactions” involve the transfer of control over, or ownership of, a specific digital wallet holding SUI or the reallocation of ownership of certain SUI in a pooled-ownership digital wallet, such as a digital wallet owned by a Digital Asset Trading Platform. In contrast to on-blockchain transactions, which are publicly recorded on the Sui Blockchain, information and data regarding off-blockchain transactions are generally not publicly available. Therefore, off-blockchain transactions are not truly Sui transactions in that they do not involve the transfer of transaction data on the Sui Network and do not reflect a movement of SUI between addresses recorded in the Sui Blockchain. For these reasons, off-blockchain transactions are subject to risks as any such transfer of SUI ownership is not protected by the protocol behind the Sui Network or recorded in, and validated through, the blockchain mechanism.

Creation of SUI

Initial Creation of SUI

Unlike other digital assets such as Bitcoin, which are solely created through a progressive mining process, 10 billion SUI were created in connection with the launch of the Sui Network. Following the launch of the Sui Network, no further SUI can be created without modifying the Sui protocol.

The initial 10 billion SUI were distributed as follows:

•

Private Sale: approximately 1.41 billion SUI, or 14.1% of the initial supply, was sold in private sales to venture capital and other investors conducted between 2021 and 2022.

•

Community Reserve: approximately 1.06 billion SUI, or 10.6% of the initial supply, was issued to be disbursed by the Sui Foundation towards supporting community-run validators and grants for developers, community ambassadors, and other similar parties.

•

Community Access Program: approximately 613 million SUI, or 6.1% of the initial supply, was offered for purchase to early contributors of the Sui ecosystem.

•

Staking Subsidies: approximately 949 million SUI, or 9.5% of the initial supply, was reserved to be released to Sui staking participants.

•

Early Contributors: approximately 582 million SUI, or 5.8% of the initial supply, was retained by core developers and contributors to compensate for their early efforts in the development of the Sui Network.

•

Mysten Treasury: approximately 163 million SUI, or 1.6% of the initial supply, was retained by Mysten to compensate for their early efforts in the development of the Sui Network.

•

Delayed Allocation: approximately 5.22 billion SUI, or 52.2% of the initial supply, was reserved for allocation after the year 2030.

Modifications to the SUI Protocol

Historically the Sui Network’s development has been overseen by the Sui Foundation, Mysten, and other core developers. The Sui Foundation, Mysten, and core developers are able to access and alter the Sui Network source code and, as a result, they are responsible for quasi-official releases of updates and other changes to the Sui Network’s source code.

For example, in July 2024, the Sui Network released version 52 of the Sui protocol, which implemented the Mysticeti consensus mechanism. The Sui Foundation and Mysten led the development of this implementation.

The release of updates to the Sui Network’s source code does not guarantee that the updates will be automatically adopted. Users and nodes must accept any changes made to the Sui source code by downloading the proposed modification of the Sui Network’s source code. If a modification is accepted only by a percentage of users and validators, a division in the Sui Network may occur such that one network will run the pre-modification source code and the other network will run the modified source code. Such a division is known as a “fork.” See “Item 1A. Risk Factors—Risk Factors Related to Digital Assets—A temporary or permanent “fork” or a “clone” could adversely affect the value of the Shares.” Consequently, as a practical matter, a modification to the source code becomes part of the Sui Network only if accepted by validators collectively having at least 83.4% of SUI staked on the Sui Network.

Core development of the Sui Network’s source code has increasingly focused on modifications of the Sui Network’s protocol to increase speed and scalability and also allow for financial and non-financial next generation uses. The Trust’s activities will not directly relate to such projects, though such projects may utilize SUI as tokens for the facilitation of their non-financial uses, thereby potentially increasing demand for SUI and the utility of the Sui Network as a whole. Conversely, projects that operate and are built within the Sui Network may increase the data flow on the Sui Network and could either “bloat” the size of the Sui Network or slow confirmation times.

Forms of Attack Against the Sui Network

All networked systems are vulnerable to various kinds of attacks. As with any computer network, the Sui Network contains certain flaws. For example, the Sui Network is currently vulnerable to attacks where, if a validator or group of validators acting in concert were to gain control of more than certain thresholds of staked SUI, a malicious actor would be able to gain full control of the network and the ability to manipulate the Sui Network. As of the date of this prospectus, no validator node individually controlled more than 3% of the voting power on the Sui Network.

In addition, many digital asset networks have been subjected to a number of denial of service attacks, which has led to temporary delays in block creation and the transfer of digital assets.

For example, on June 19, 2023, smart-contract audit firm Certik disclosed that they had discovered a bug in the Sui code that could cause a type of denial of service attack that could cause the Sui Network to go offline and cease full functionality. Certik apparently disclosed the vulnerability to the Sui Foundation and Mysten before the Sui Network’s launch, so it could be fixed unilaterally. However, had the vulnerability been exploited after the network was launched, while persons associated with the Sui Foundation and/or Mysten would have likely played a key role in bringing the network back online, the broader community would have had to play a key role, as Sui Network validators would have had to coordinate to upgrade and restart the network. Any similar attacks on the Sui Network that impact the ability to transfer SUI could have a material adverse effect on the price of SUI and the value of the Shares.

Market Participants

Validators

Validators range from Sui enthusiasts to professional operations that design and build dedicated machines and data centers, including “clusters,” which are groups of validators that act cohesively and combine their processing to confirm transactions. When a validator confirms a transaction, the validator and any associated stakers receive a fee. During the course of ordering transactions and validating blocks, validators may be able to prioritize certain transactions in return for increased transaction fees, an incentive system known as “Maximal Extractable Value” or MEV. For example, in blockchain networks that facilitate DeFi protocols in particular, such as the Ethereum Network, users may attempt to gain an advantage over other users by offering greater transaction fees. Validators less commonly capture MEV in the Sui Network because, unlike the Ethereum Network, it does not publicly expose transactions before they

are accepted by a validator. However, some efforts are underway to help SUI validators consistently capture MEV. See “—Summary of a SUI Transaction” above.

Investment and Speculative Sector

This sector includes the investment and trading activities of both private and professional investors and speculators. Historically, larger financial services institutions are publicly reported to have limited involvement in investment and trading in digital assets, although the participation landscape is beginning to change. Currently, there is relatively limited use of digital assets in the retail and commercial marketplace in comparison to relatively extensive use by speculators, and a significant portion of demand for digital assets is generated by speculators and investors seeking to profit from the short- or long-term holding of digital assets.

Retail Sector

The retail sector includes users transacting in direct peer-to-peer SUI transactions through the direct sending of SUI over the Sui Network. The retail sector also includes transactions in which consumers purchase goods and services from commercial or service businesses through direct transactions or third-party service providers, although the use of SUI as a means of payment is still developing and has not yet been accepted in the same manner as Bitcoin or Ether due to its infancy and because SUI has a different purpose than Bitcoin and Ether.

Service Sector

This sector includes companies that provide a variety of services including the buying, selling, payment processing and storing of SUI. For buying and selling SUI, Bitfinex, Bitstamp by Robinhood, Bullish, Bybit, Crypto.com, Kraken, and OKX are some of the largest Digital Asset Trading Platforms by volume traded. For storing SUI, Coinbase Custody Trust Company, LLC, the Custodian for the Trust, is a digital asset custodian that provides custodial accounts that store SUI for users. As SUI continues to grow in acceptance, it is anticipated that service providers will expand the currently available range of services and that additional parties will enter the service sector for SUI.

Competition

Thousands of digital assets have been developed since the inception of Bitcoin, which is currently one of the most developed digital asset because of the length of time it has been in existence, the investment in the infrastructure that supports it, and the network of individuals and entities that are using Bitcoin in transactions. While SUI has enjoyed some success in its limited history, the aggregate value of outstanding SUI is much smaller than that of Bitcoin and many other digital assets and may be further eclipsed by the more rapid development of other digital assets. In addition, a number of other digital assets also function as smart contract platforms, including the Ethereum Network, the Avalanche network and the Cardano network.

Some industry groups are also creating private, permissioned blockchain versions of digital asset technologies. For example, J.P. Morgan is developing a platform called Kinexys, which is described as a blockchain-based platform designed for use by the financial services industry.

SUI Value

Digital Asset Trading Platform Valuation

The value of SUI is determined by the value that various market participants place on SUI through their transactions. The most common means of determining the value of a SUI is by surveying one or more Digital Asset Trading Platforms where SUI is traded publicly and transparently. Additionally, there are over-the-counter dealers or market makers that transact in SUI.

Prior to December 19, 2025, the Trust valued the SUI held by the Trust for operational purposes by reference to the CoinDesk SUI Reference Rate Price. Effective December 19, 2025, the Index was changed to the CoinDesk Sui Benchmark Rate (formerly known as the CoinDesk SUI CCIXber Reference Rate).

Digital Asset Trading Platform Public Market Data

On each online Digital Asset Trading Platform, SUI is traded with publicly disclosed valuations for each executed trade, measured by one or more fiat currencies such as the U.S. dollar or euro, or stablecoins such as U.S. Dollar Coin (“USDC”). Over-the-counter dealers or market makers do not typically disclose their trade data.

As of December 31, 2025, the Digital Asset Trading Platforms included in the Index were Bitfinex, Bitstamp by Robinhood, Bullish, Bybit, Crypto.com, Kraken, and OKX. The Sponsor and the Trust reasonably believe each of these Digital Asset Trading

Platforms are in material compliance with applicable licensing requirements based on the inclusion criteria and jurisdiction, as detailed below, and maintain practices and policies designed to comply with anti-money laundering (“AML”) and know-your-customer (“KYC”) regulations.

Bitfinex: A British Virgin Islands based trading platform. Bitfinex does not hold any licenses or registrations in the U.S. and is not available to U.S.-based customers.

Bitstamp by Robinhood: A U.K.-based trading platform that has U.S. operations and entities registered as money service businesses (“MSBs”) with the U.S. Department of the Treasury’s Financial Crimes Enforcement Network (“FinCEN”), holds a BitLicense, and that is licensed as a money transmitter in various U.S. states.

Bullish: A Gibraltar-based trading platform that has entities registered as MSBs with FinCEN, and that is licensed as a virtual currency business under the New York State Department of Financial Services’ (“NYDFS”) BitLicense.

Bybit: A United Arab Emirates-based trading platform. Bybit does not hold any licenses or registrations in the U.S. and is not available to U.S. based customers.

Crypto.com: A Singapore-based trading platform that has entities registered as MSBs with FinCEN, and that is licensed as a money transmitter in various U.S. states and chartered as a non-depository trust company by the New Hampshire Banking Department. Crypto.com does not hold a BitLicense.

Kraken: A U.S.-based trading platform that has entities registered as MSBs with FinCEN, and that is licensed as a money transmitter in various U.S. states, and chartered as a Special Purpose Depository Institution by the Wyoming Division of Banking. Kraken does not hold a BitLicense.

OKX: A Seychelles-based trading platform. OKX does not hold any licenses or registrations in the U.S. and is not available to U.S.-based customers.

Currently, there are several Digital Asset Trading Platforms operating worldwide, and online Digital Asset Trading Platforms represent a substantial percentage of SUI buying and selling activity and provide the most data with respect to prevailing valuations of SUI. These trading platforms include established trading platforms such as the Digital Asset Trading Platforms included in the Index, which provide a number of options for buying and selling SUI. The below table reflects the trading volume in SUI and market share of the SUI-U.S. dollar and SUI-USDC trading pairs of each of the Digital Asset Trading Platforms included in the Index as of December 31, 2025 (collectively, “Constituent Trading Platforms”), using data since January 1, 2024:


Digital Asset Trading Platforms included in the Index as of December 31, 2025(1)	Volume (SUI)		Market Share(2)
Kraken		2,368,500,538		12.96	%
Crypto.com		434,859,291		2.38	%
Bitstamp by Robinhood		352,737,372		1.93	%
Bitfinex		68,175,844		0.37	%
OKX		15,073,201		0.08	%
Total SUI-U.S. dollar trading pair		3,239,346,247		17.72	%


Digital Asset Trading Platforms included in the Index as of December 31, 2025	Volume (SUI)		Market Share(2)

(1)

On March 17, 2026, the Index Provider added HashKey to the Index due to the trading platform meeting the Index Provider’s minimum liquidity requirement, and did not remove any Constituent Trading Platforms as part of its scheduled monthly review.

(2)

Market share is calculated using trading volume (in SUI) for certain Digital Asset Trading Platforms including, Bitfinex, Bullish, Bybit, Bitstamp by Robinhood, Crypto.com, Kraken, and OKX, as well as certain other large U.S.-dollar denominated Digital Asset Trading Platforms that were not included in the Index as of December 31, 2025, including Coinbase, Binance, Gate, KuCoin, and MEXC.

The domicile, regulation and legal compliance of the Digital Asset Trading Platforms included in the Index varies. Information regarding each Digital Asset Trading Platform may be found, where available, on the websites for such Digital Asset Trading Platforms, among other places.

Although the Index is designed to accurately capture the market price of SUI, third parties may be able to purchase and sell SUI on public or private markets not included among the constituent Digital Asset Trading Platforms of the Index, and such transactions

may take place at prices materially higher or lower than the Index Price. Moreover, there may be variances in the prices of SUI on the various Digital Asset Trading Platforms, including as a result of differences in fee structures or administrative procedures on different Digital Asset Trading Platforms. For example, based on data provided by the Index Provider, on any given day during the year ended December 31, 2025, the maximum differential between the 4:00 p.m., New York time, spot price of any single Digital Asset Trading Platform included in the Index and the Index Price was 2.49% and the average of the maximum differentials of the 4:00 p.m., New York time, spot price of each Digital Asset Trading Platform included in the Index and the Index Price was 0.98%. During this same period, the average differential between the 4:00 p.m., New York time, spot prices of all the Digital Asset Trading Platforms included in the Index and the Index Price was 0.01%.

To the extent such prices differ materially from the Index Price, investors may lose confidence in the Shares’ ability to track the market price of SUI.

The Index and the Index Price

The Index is a U.S. dollar-denominated composite reference rate for the price of SUI. The Index is designed to (1) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the SUI reference rate, (2) provide a real-time, volume-weighted fair value of SUI and (3) appropriately handle and adjust for non-market related events.

The Index Price is determined by the Index Provider through a process in which trade data is cleansed and compiled in such a manner as to algorithmically reduce the impact of anomalistic or manipulative trading. This is accomplished by adjusting the weight of each data input based on price deviation relative to the observable set, as well as recent and long-term trading volume at each venue relative to the observable set. The Index Price is calculated using non-GAAP methodology and is not used in the Trust’s financial statements.

All references to the NAV and NAV per Share of the Trust in this report have been calculated using the Index Price unless indicated otherwise.

All references to the NAV and NAV per Share of the Trust in this Annual Report prior to December 19, 2025 have been calculated using the Index Price based on the CoinDesk SUI Reference Rate Price unless otherwise indicated. Effective December 19, 2025, the NAV and NAV per Share of the Trust is calculated using the Index Price based on the CoinDesk Sui Benchmark Rate.

Constituent Trading Platform Selection

Digital Asset Trading Platforms are selected for inclusion in the Index based on a methodology developed by the Index Provider in alignment with the International Organization of Securities Commissions (“IOSCO”) Principles for Financial Benchmarks. To qualify as a Constituent Trading Platform, a platform is evaluated across the following core criteria listed below (the “Inclusion Criteria”):

•

Market Quality: Overall liquidity, trading activity, price reliability, and market stability.

•

Security: Cybersecurity safeguards, custody practices, and operational risk controls.

•

Legal and Regulatory: Licensing status, regulatory compliance, and legal transparency.

•

KYC: Assessment of anti-money laundering (“AML”) and know-your-customer (“KYC”) frameworks, transaction monitoring capabilities, and market oversight.

•

Data Provision: Quality, accessibility, and reliability of trading data and technical infrastructure.

•

Transparency: Financial and operational disclosures, including reserve and governance transparency.

•

Team: Assessment of executive leadership, relevant experience, organizational structure, and service offerings across institutional and retail markets.

•

Negative Events: The Index Provider may apply a downward adjustment for material adverse events, including data breaches, regulatory penalties, withdrawal freezes, or other significant incidents.

Trading platforms that meet these Inclusion Criteria are also required to be licensed and able to serve customers in one or more of the following jurisdictions:

•

United States (FinCEN, state regulatory authorities)

•

United Kingdom (FCA)

•

European Union (MiCA passport)

•

Hong Kong (SFC)

•

Singapore (MAS)

•

United Arab Emirates, including the emirates of Dubai and Abu Dhabi (VARA, ADGM)

•

Gibraltar (GFSC)

A Digital Asset Trading Platform is removed from the Constituent Trading Platforms when it no longer satisfies the Inclusion Criteria. The Index Provider may also exclude certain trading platforms that require additional support from contributing trading platforms at its discretion. The Index Provider does not currently include data from over-the-counter markets or derivatives platforms among the Constituent Trading Platforms. Over-the-counter data is not currently included because of the potential for trades to include a significant premium or discount paid for larger liquidity, which creates an uneven comparison relative to more active markets. There is also a higher potential for over-the-counter transactions to not be arms-length, and thus not be representative of a true market price. SUI derivative markets are also not currently included. While the Index Provider has no plans to include data from over-the-counter markets or derivative platforms at this time, the Index Provider will consider IOSCO principles for financial benchmarks, the management of trading venues of SUI derivatives and the aforementioned Inclusion Criteria when considering whether to include over-the-counter or derivative platform data in the future.

The Index Provider and the Sponsor have entered into the index license agreement, dated as of February 1, 2022 (as amended, the “Index License Agreement”), governing the Sponsor’s use of the Index Price. Pursuant to the terms of the Index License Agreement, the Index Provider may adjust the calculation methodology for the Index Price without notice to, or consent of, the Trust or its shareholders. The Index Provider may decide to change the calculation methodology to maintain the integrity of the Index Price calculation should it identify or become aware of previously unknown variables or issues with the existing methodology that it believes could materially impact its performance and/or reliability. The Index Provider has sole discretion over the determination of the Index Price and may change the methodologies for determining the Index Price from time to time. Shareholders will be notified of any material changes to the calculation methodology or the Index Price in the Trust’s current reports and will be notified of all other changes that the Sponsor considers significant in the Trust’s periodic or current reports. The Sponsor will determine the materiality of any changes to the Index Price on a case-by-case basis, in consultation with external counsel.

The Index Provider may change the trading venues that are used to calculate the Index or otherwise change the way in which the Index is calculated at any time. For example, the Index Provider has scheduled monthly reviews in which it may add or remove Constituent Trading Platforms that satisfy or fail the Inclusion Criteria as well as other requirements detailed in the Index Methodology. The Index Provider does not have any obligation to consider the interests of the Sponsor, the Trust, the shareholders, or anyone else in connection with such changes. While the Index Provider is not required to publicize or explain the changes or to alert the Sponsor to such changes, it has historically notified the Trust of certain changes to the Constituent Trading Platforms, including any additions or removals of the Constituent Trading Platforms, in addition to issuing press releases in connection with the same. The Sponsor will provide updates of such changes in the Trust’s quarterly reports on Form 10-Q. Although the Index methodology is designed to operate without any manual intervention, rare events would justify manual intervention. Intervention of this kind would be in response to non-market-related events, such as the halting of deposits or withdrawals of funds on a Digital Asset Trading Platform, the unannounced closure of operations on a Digital Asset Trading Platform, insolvency or the compromise of user funds. In the event that such an intervention is necessary, the Index Provider would issue a public announcement through its website, API and other established communication channels with its clients.

Determination of the Index Price

The Index applies an algorithm to the price of SUI on the Constituent Trading Platforms calculated every 5 seconds over a 24-hour period. The Index’s algorithm is expected to reflect a five-pronged methodology to calculate the Index Price from the Constituent Trading Platforms:

•

Volume Weighting: Constituent Trading Platforms with greater liquidity receive a higher weighting in each Index, increasing the ability to execute against (i.e., replicate) the Index in the underlying spot markets. The Index methodology is a volume-weighted real-time price where the latest trade price for each Constituent Trading Platform is weighted based on its trailing 24-hour volume.

•

FX Conversion: The Index algorithm utilizes a volume-weighted real-time FX conversion rate for any trading activity for the relevant Stablecoin-USD pair. This normalizes all trading activity to USD denomination.

•

Outlier Detection Factor: The Index algorithm excludes trade data and price(s) deemed to be an outlier relative to the most recently calculated Index.

•

Inactivity Adjustment: The Index algorithm penalizes stale activity from any given Constituent Trading Platform. When a Constituent Trading Platform does not have recent trading data, the outdated prices and their contribution to the Index

calculation are gradually reduced until they are de-weighted to 0.1%. Similarly, once trading activity at a Constituent Trading Platform resumes, the corresponding weighting for that Constituent Trading Platform will no longer be penalized.

•

Manipulation Resistance: In an effort to determine and prioritize the most significant Constituent Trading Platforms (i.e., those that are likely to have the most impact on price discovery) for a given asset, the Index Provider conducts a Constituent Trading Platform selection and review process, which seeks to identify the highest-ranking Constituent Trading Platforms based on both qualitative and quantitative factors. The qualitative review includes legal and regulation, data provision, security, trade monitoring, market quality, and negative events policy, among others. The quantitative review includes review of trading activity for the asset on the given Constituent Trading Platform.

The Index Provider re-evaluates the weighting algorithm on a periodic basis, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms.

The Sponsor believes the Index Provider’s selection process for Constituent Trading Platforms as well as the methodology of the Index Price’s algorithm provides a more accurate picture of SUI price movements than a simple average of Digital Asset Trading Platform spot prices, and that the weighting of SUI prices on the Constituent Trading Platforms limits the inclusion of data that is influenced by temporary price dislocations that may result from technical problems, limited liquidity or fraudulent activity elsewhere in the SUI spot market.

By referencing multiple trading venues and weighting them based on trade activity, the Sponsor believes that the impact of any potential fraud, manipulation or anomalous trading activity occurring on any single venue is reduced.

If the Index Price becomes unavailable, or if the Sponsor determines in good faith that such Index Price does not reflect an accurate price for SUI , then the Sponsor will contact the Index Provider to obtain the Index Price directly from the Index Provider. If after such contact such Index Price remains unavailable or the Sponsor continues to believe in good faith that such Index Price does not reflect an accurate price for SUI , then the Sponsor will employ a cascading set of rules to determine the Index Price, as described below in “—Determination of the Index Price When Index Price is Unavailable.”

The Trust values its SUI for operational purposes by reference to the Index Price. The Index Price is the value of a SUI as represented by the Index, calculated at 4:00 p.m., New York time, on each business day.

Illustrative Example

For the purposes of illustration, outlined below are examples of how the attributes that impact weighting and adjustments in the aforementioned methodology may be utilized to generate the Index Price for a digital asset.

For example, the Constituent Trading Platforms used to calculate the Index Price of the digital asset may include trading platforms such as Crypto.com, Kraken, LMAX Digital and Bitstamp by Robinhood.

The Index Price algorithm, as described above, is designed to account for manipulation at the outset by only including data from executed trades on Constituent Trading Platforms that charge trading fees. Then, the below-listed elements may impact the weighting of the Constituent Trading Platforms on the Index Price as follows:

•

Volume Weighting: Each Constituent Trading Platform will be weighted to appropriately reflect the trading volume share of the Constituent Trading Platform relative to all the Constituent Trading Platforms during this same period. For example, a weighting of 67.06%, 14.57%, 11.88%, and 6.49% for Crypto.com, Kraken, LMAX Digital and Bitstamp by Robinhood, respectively, would represent each Constituent Trading Platform’s share of trading volume during the preceding 24 hours.

•

Inactivity Adjustment: Assume that a Constituent Trading Platform represented a 14% weighting on the Index Price of the digital asset and then went offline for approximately two hours. The index algorithm would automatically recognize inactivity and start de-weighting the Constituent Trading Platform at the 5-minute mark and continue to do so with each additional 5-minute period of inactivity until its influence was effectively zero, 25 minutes after becoming inactive. As soon as trading activity resumed at the Constituent Trading Platform, the index algorithm would re-weight it to the appropriate weighting based on trading volume and price-variance relative to the cohort of Constituent Trading Platforms included in the Index.

•

Price Outlier Detection: New traded prices from Constituent Trading Platforms are compared to the latest calculated Index Price. If a new traded price deviates by +/- 5% from the latest calculated Index Price, it will be considered an outlier and will not be used in the calculation of the Index Price until such time as a majority of the Constituent Trading Platforms are similarly considered outlier prices. In that case, the new prices will be used to calculate the Index Price. For example, if

the Index Price is $10 and there is a new trade price of $11 from Constituent Trading Platform X, the price of $11 will be considered an outlier and will not be used. However, if the most recent prices on a majority of the Constituent Trading Platforms are aligned with the price of $11, then these prices will no longer be considered outliers and will be used to calculate the new Index Price.

Determination of the Index Price When Index Price is Unavailable

The Sponsor uses the following cascading set of rules to calculate the Index Price. For the avoidance of doubt, the Sponsor will employ the below rules sequentially and in the order as presented below, should one or more specific rule(s) fail:

Index Price = The price set by the Index as of 4:00 p.m., New York time, on the valuation date. If the Index becomes unavailable, or if the Sponsor determines in good faith that the Index does not reflect an accurate price, then the Sponsor will, on a best efforts basis, contact the Index Provider to obtain the Index Price directly from the Index Provider. If after such contact the Index remains unavailable or the Sponsor continues to believe in good faith that the Index does not reflect an accurate price, then the Sponsor will employ the next rule to determine the Index Price. There are no predefined criteria to make a good faith assessment and it will be made by the Sponsor in its sole discretion.

Index Price = The price set by Coin Metrics Real-Time Rate (the “Secondary Index”) as of 4:00 p.m., New York time, on the valuation date (the “Secondary Index Price”). The Secondary Index Price is a real-time reference rate price, calculated using trade data from constituent markets selected by Coin Metrics, Inc. (the “Secondary Index Provider”). The Secondary Index Price is calculated by applying weighted-median techniques to such trade data where half the weight is derived from the trading volume on each constituent market and half is derived from inverse price variance, where a constituent market with high price variance as a result of outliers or market anomalies compared to other constituent markets is assigned a smaller weight. The Secondary Index Provider and the Sponsor have entered into the master services agreement, dated as of August 4, 2020, and order forms thereunder, pursuant to which the Sponsor may obtain and use the Secondary Index and the Secondary Index Price from the Secondary Index Provider. If the Secondary Index becomes unavailable, or if the Sponsor determines in good faith that the Secondary Index does not reflect an accurate price, then the Sponsor will, on a best efforts basis, contact the Secondary Index Provider to obtain the Secondary Index Price directly from the Secondary Index Provider. If after such contact the Secondary Index remains unavailable or the Sponsor continues to believe in good faith that the Secondary Index does not reflect an accurate price, then the Sponsor will employ the next rule to determine the Index Price. There are no predefined criteria to make a good faith assessment and it will be made by the Sponsor in its sole discretion.

Index Price = The price set by the Trust’s principal market (the “Tertiary Pricing Option”) as of 4:00 p.m., New York time, on the valuation date. The Tertiary Pricing Option is a spot price derived from the principal market’s public data feed that is believed to be consistently publishing pricing information as of 4:00 p.m., New York time, and is provided to the Sponsor via an application programming interface. If the Tertiary Pricing Option becomes unavailable, or if the Sponsor determines in good faith that the Tertiary Pricing Option does not reflect an accurate price, then the Sponsor will, on a best efforts basis, contact the Tertiary Pricing Provider to obtain the Tertiary Pricing Option directly from the Tertiary Pricing Provider. If after such contact the Tertiary Pricing Option remains unavailable or the Sponsor continues to believe in good faith that the Tertiary Pricing Option does not reflect an accurate price, then the Sponsor will employ the next rule to determine the Index Price. There are no predefined criteria to make a good faith assessment and it will be made by the Sponsor in its sole discretion.

Index Price = The Sponsor will use its best judgment to determine a good faith estimate of the Index Price. There are no predefined criteria to make a good faith assessment and it will be made by the Sponsor in its sole discretion.

In the event of a fork, the Index Provider may calculate the Index Price based on a digital asset that the Sponsor does not believe to be the appropriate asset that is held by the Trust. In this event, the Sponsor has full discretion to use a different index provider or calculate the Index Price itself using its best judgment.

The Sponsor may, in its sole discretion, select a different index provider, select a different index price provided by the Index Provider, calculate the Index Price by using the cascading set of rules set forth above, or change the cascading set of rules set forth above at any time. The Sponsor will provide notice of any such changes in the Trust’s periodic or current reports and, if the Sponsor makes such a change other than on an ad hoc or temporary basis, will file a proposed rule change with the SEC.

Government Oversight

As digital assets have grown in both popularity and market size, the U.S. Congress and a number of U.S. federal and state agencies (including FinCEN, the Treasury Department Office of Foreign Assets Control (“OFAC”), SEC, CFTC, the Financial Industry Regulatory Authority (“FINRA”), the Consumer Financial Protection Bureau (“CFPB”), the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the U.S. Internal Revenue Service, a bureau of the U.S. Department of the

Treasury (the “IRS”), the Office of the Comptroller of the Currency, the Federal Deposit Insurance Corporation, the Federal Reserve and state financial institution and securities regulators) have been examining the operations of digital asset networks, digital asset users and the digital asset markets, with particular focus on the extent to which digital assets can be used to launder the proceeds of illegal activities, evade sanctions or fund criminal or terrorist enterprises and the safety and soundness of trading platforms and other service providers that hold or custody digital assets for users. Many of these state and federal agencies have issued consumer advisories regarding the risks posed by digital assets to investors. In addition, federal and state agencies, and other countries and international bodies have issued rules or guidance about the treatment of digital asset transactions or requirements for businesses engaged in digital asset activity. Moreover, the failure of FTX Trading Ltd. (“FTX”) in November 2022 and the resulting market turmoil substantially increased regulatory scrutiny in the United States and globally and led to SEC enforcement actions, criminal investigations, and other regulatory activity across the digital asset ecosystem.

In addition, the SEC, U.S. state securities regulators and several foreign governments have issued warnings and instituted legal proceedings in which they argue that certain digital assets may be classified as securities and that both those digital assets and any related initial coin offerings or other primary and secondary market transactions are subject to securities regulations. For example, in June 2023, the SEC brought charges against Binance Holdings Ltd. (the “Binance Complaint”) and Coinbase, Inc. (the “Coinbase Complaint”), and in November 2023, the SEC brought charges against Kraken (the “Kraken Complaint”), alleging that they operated unregistered securities exchanges, brokerages and clearing agencies. In its complaints, the SEC asserted that several digital assets are securities under the federal securities laws. Between February 2025 and May 2025, the SEC entered into court-approved joint stipulations to dismiss each of the Binance Complaint, Coinbase Complaint and the Kraken Complaint. The SEC has terminated its investigation or enforcement action into many other digital asset market participants as well. Additionally, U.S. state and federal, and foreign regulators and legislatures have taken action against virtual currency businesses or enacted restrictive regimes in response to adverse publicity arising from hacks, consumer harm, or criminal activity stemming from virtual currency activity.

On March 17, 2026, the SEC issued an interpretation clarifying how the federal securities laws apply to certain crypto assets and transactions involving crypto assets. The SEC interpretation (i) provides a taxonomy for digital commodities, digital collectibles, digital tools, stablecoins and digital securities; (ii) addresses how a “non-security crypto asset” may become subject to, and how it may cease to be subject to, an investment contract; and (iii) clarifies the application of federal securities laws to airdrops, protocol mining, protocol staking and the wrapping of a non-security crypto asset. The CFTC joined the interpretation to provide guidance that the CFTC and its staff will administer the Commodity Exchange Act consistent with the SEC's interpretation.

There have been several bills introduced in Congress that propose to establish additional regulation and oversight of the digital asset markets. Certain of these bills passed out of relevant committees and were passed in the House of Representatives in the last Congress, though not the Senate. Some of these bills have since been reintroduced with changes, and continue to be contemplated in the relevant committees, as well as the full House of Representatives and Senate. For example, in July 2025, the GENIUS Act was signed into law and the House of Representatives passed the Digital Asset Market Clarity Act of 2025 (“CLARITY Act”) in an effort to pass laws relating to digital asset market structure. It is difficult to predict whether, or when, any of these developments will lead to Congress granting additional authorities to the SEC or other regulators, what the nature of such additional authorities might be, how additional legislation and/or regulatory oversight might impact the ability of digital asset markets to function or how any new regulations or changes to existing regulations might impact the value of digital assets. See “Item 1A. Risk Factors—Risk Factors Related to the Regulation of Digital Assets, the Trust and the Shares— Regulatory changes or actions by the U.S. Congress or any U.S. federal or state agencies may affect the value of the Shares or restrict the use of SUI, validating activity or the operation of the Sui Network or the Digital Asset Markets in a manner that adversely affects the value of the Shares,” and “Item 1A. Risk Factors—Risk Factors Related to the Regulation of Digital Assets, the Trust and the Shares—A determination that SUI or any other digital asset is or involves a transaction in a “security” may adversely affect the value of SUI and the value of the Shares, and result in potentially extraordinary, nonrecurring expenses to, or termination of, the Trust.”

Various foreign jurisdictions have, and may continue to, in the near future, adopt laws, regulations or directives that affect a digital asset network, the Digital Asset Markets, and their users, particularly Digital Asset Trading Platforms and service providers that fall within such jurisdictions’ regulatory scope. For example:

•

China has made transacting in cryptocurrencies illegal for Chinese citizens in mainland China, and additional restrictions may follow. China has banned initial coin offerings and there have been reports that Chinese regulators have taken action to shut down a number of China-based Digital Asset Trading Platforms.

•

South Korea determined to amend its Financial Information Act in March 2020 to require virtual asset service providers to register and comply with its AML and counter-terrorism funding framework. These measures also provide the government with the authority to close Digital Asset Trading Platforms that do not comply with specified processes. South Korea has also banned initial coin offerings.

•

The Reserve Bank of India in April 2018 banned the entities it regulates from providing services to any individuals or business entities dealing with or settling digital assets. In March 2020, this ban was overturned in the Indian Supreme Court, although the Reserve Bank of India is currently challenging this ruling.

•

The United Kingdom’s Financial Conduct Authority published final rules in October 2020 banning the sale of derivatives and exchange-traded notes that reference certain types of digital assets, contending that they are “ill-suited” to retail investors citing extreme volatility, valuation challenges and association with financial crime. A new law, the Financial Services and Markets Act 2023 (“FSMA”), received royal assent in June 2023. The FSMA brings digital asset activities within the scope of existing laws governing financial institutions, markets and assets.

•

The Parliament of the European Union approved the text of the Markets in Crypto-Assets Regulation (“MiCA”) in April 2023, establishing a regulatory framework for digital asset services across the European Union. MiCA is intended to serve as a comprehensive regulation of digital asset markets and imposes various obligations on digital asset issuers and service providers. The main aims of MiCA are industry regulation, consumer protection, prevention of market abuse and upholding the integrity of digital asset markets. MiCA was formally approved by the European Union’s member states in 2023. Certain parts of MiCA became effective as of June 2024 and the remainder applied as of December 2024.

There remains significant uncertainty regarding foreign governments’ future actions with respect to the regulation of digital assets and Digital Asset Trading Platforms. Such laws, regulations or directives may conflict with those of the United States and may negatively impact the acceptance of SUI by users, merchants and service providers outside the United States and may therefore impede the growth or sustainability of the Sui ecosystem in the United States and globally, or otherwise negatively affect the value of SUI held by the Trust. The effect of any future regulatory change on the Trust or the SUI held by the Trust is impossible to predict, but such change could be substantial and adverse to the Trust and the value of the Shares.

The CFTC has regulatory jurisdiction over the SUI futures markets because the CFTC believes that most digital assets are non-security "commodities" under the CEA and the rules thereunder, it takes the position that it has jurisdiction to prosecute fraud and manipulation in the cash or spot market for those non-security digital assets. Beyond instances of fraud or manipulation, the CFTC generally does not oversee cash or spot market exchanges, spot Digital Asset Trading Platforms or transactions involving spot SUI that do not utilize collateral, leverage, or financing. The National Futures Association (“NFA”) is the self-regulatory agency for the U.S. futures industry, and as such has jurisdiction over SUI futures. However, the NFA does not have regulatory oversight authority for the cash or spot market for SUI trading or transactions.

In September 2025 Coinbase Derivatives as a designated contract market (“DCM”) registered with the CFTC launched new contracts for SUI futures products. DCMs are boards of trades (commonly referred to as exchanges) that operate under the regulatory oversight of the CFTC, pursuant to Section 5 of the CEA. To obtain and maintain designation as a DCM, an exchange must comply on an initial and ongoing basis with twenty-three Core Principles established under Section 5(d) of the CEA. Among other things, DCMs are required to establish self-regulatory programs designed to enforce the DCM’s rules, prevent market manipulation and customer and market abuses, and ensure the recording and safe storage of trade information.

The Coinbase Derivatives SUI futures contracts are cash-settled, based on the MarketVector Coinbase Sui Benchmark Rate. On August 4, 2025, CFTC Acting Chairman Caroline D. Pham announced that the CFTC will launch an initiative for trading spot crypto asset contracts that are listed on a CFTC-registered futures exchange (DCM). This is the first initiative in the CFTC’s “crypto sprint” to start implementation of the recommendations in the President’s Working Group on Digital Asset Markets report. Members of the public were invited to provide written input by August 18, 2025 through the CFTC website.

See “Item 1A. Risk Factors—Risk Factors Related to the Regulation of Digital Assets, the Trust and the Shares—Regulatory changes or actions by the U.S. Congress or any U.S. federal or state agencies may affect the value of the Shares or restrict the use of SUI, validating activity or the operation of the Sui Network or the Digital Asset Markets in a manner that adversely affects the value of the Shares.”

Description of the Trust

The Trust is a Delaware Statutory Trust that was formed on April 30, 2024 by the filing of the Certificate of Trust with the Delaware Secretary of State in accordance with the provisions of the Delaware Statutory Trust Act (“DSTA”). On February 18, 2026, the Trust changed its name from Grayscale Sui Trust (SUI) to Grayscale Sui Staking ETF by filing a Certificate of Amendment to the

Certificate of Trust with the Delaware Secretary of State in accordance with the provisions of the DSTA. The Trust operates pursuant to the Trust Agreement.

The Shares represent units of fractional undivided beneficial interest in and ownership of the Trust. The Trust is passive and is not managed like a corporation or an active investment vehicle. The Trust’s SUI are held by the Custodian on behalf of the Trust. The Trust’s SUI will be transferred out of the Vault Balance only in the following circumstances: (i) transferred to pay the Sponsor’s Fee or any Additional Trust Expenses, (ii) sold on an as-needed basis to pay Additional Trust Expenses or (iii) sold on behalf of the Trust in the event the Trust terminates and liquidates its assets or as otherwise required by law or regulation. Assuming that the Trust is treated as a grantor trust for U.S. federal income tax purposes, each delivery or sale of SUI by the Trust to pay the Sponsor’s Fee or any Additional Trust Expenses will be a taxable event for shareholders. See “—Material U.S. Federal Income Tax Consequences—Tax Consequences to U.S. Holders.”

The Trust is not a registered investment company under the Investment Company Act and the Sponsor believes that the Trust is not required to register under the Investment Company Act. The Trust will not trade, buy, sell or hold SUI derivatives, including SUI futures contracts, on any futures exchange. The Trust is authorized solely to take immediate delivery of actual SUI. The Sponsor does not believe the Trust’s activities are required to be regulated by the CFTC under the CEA as a “commodity pool” under current law, regulation and interpretation. The Trust will not be operated by a CFTC-regulated commodity pool operator because it will not trade, buy, sell or hold SUI derivatives, including SUI futures contracts, on any futures exchange. Investors in the Trust will not receive the regulatory protections afforded to investors in regulated commodity pools, nor may the COMEX division of the New York Mercantile Exchange or any futures exchange enforce its rules with respect to the Trust’s activities. In addition, investors in the Trust will not benefit from the protections afforded to investors in SUI futures contracts on regulated futures exchanges.

The Trust creates and redeems Shares from time to time but only in Baskets. A Basket equals a block of 10,000 Shares. See“—Description of Creation and Redemption of Shares.” The Sponsor will determine the Trust’s NAV on each business day as of 4:00 p.m., New York time, or as soon thereafter as practicable. The Sponsor will also determine the NAV per Share, which equals the NAV divided by the number of outstanding Shares. Each business day, the Sponsor will publish the Trust’s NAV and NAV per Share on the Trust’s website, etfs.grayscale.com/gsui, as soon as practicable after the Trust’s NAV and NAV per Share have been determined by the Sponsor. See “—Valuation of SUI and Determination of NAV.”

The Trust’s assets consist solely of SUI, cash proceeds from the sale of SUI and any rights of the Trust pursuant to any agreements, other than the Trust Agreement, to which the Trust is a party. The Sponsor has committed to cause the Trust not to take any Affirmative Action to acquire any Incidental Rights or IR Virtual Currency, thereby irrevocably abandoning any Incidental Rights and IR Virtual Currency to which the Trust may become entitled in the future. As a result, the Trust does not expect to hold any Incidental Rights or IR Virtual Currency or to take any Incidental Rights or IR Virtual Currency into account for the purposes of determining the NAV or the NAV per Share.

Each Share represents a proportional interest, based on the total number of Shares outstanding, in each of the Trust’s assets as determined in the case of SUI by reference to the Index Price, less the Trust’s expenses and other liabilities (which include accrued but unpaid fees and expenses). The Sponsor expects that the market price of the Shares will fluctuate over time in response to the market prices of SUI. In addition, because the Shares reflect the estimated accrued but unpaid expenses of the Trust, the amount of SUI represented by a Share will gradually decrease over time as the Trust’s SUI are used to pay the Trust’s expenses.

SUI pricing information is available on a 24-hour basis from various financial information service providers or Sui Network information sites, such as CoinMarketCap.com. The spot price and bid/ask spreads may also be available directly from Digital Asset Trading Platforms. As of December 31, 2025, the Constituent Trading Platforms of the Index were Bitfinex, Bitstamp by Robinhood, Bullish, Bybit, Crypto.com, Kraken, and OKX. The Index Provider may remove or add Digital Asset Trading Platforms to the Index in the future at its discretion. Market prices for the Shares will be available from a variety of sources, including brokerage firms, information websites and other information service providers. In addition, on each business day the Trust’s website will provide pricing information for the Shares.

The Trust has no fixed termination date.

Service Providers of the Trust

The Sponsor

As of the date of this Annual Report, the Trust’s Sponsor is Grayscale Investments Sponsors, LLC. Until December 31, 2024, the Trust’s Sponsor was Grayscale Investments, LLC, a Delaware limited liability company formed on May 29, 2013 and a consolidated subsidiary of DCG. See “—Overview of the Trust and the Shares” for more information regarding the Reorganization on January 1, 2025. The Sponsor’s principal place of business is 290 Harbor Drive, 4th Floor, Stamford, Connecticut 06902, and its telephone number

is (212) 668-1427. Under the Delaware Limited Liability Company Act and the governing documents of the Sponsor, DCG, the indirect parent company of the Sponsor, is not responsible for the debts, obligations and liabilities of the Sponsor solely by reason of being the indirect parent company of the Sponsor.

The Sponsor is neither an investment adviser registered with the SEC nor a commodity pool operator registered with the CFTC, and will not be acting in either such capacity with respect to the Trust, and the Sponsor’s provision of services to the Trust will not be governed by the Investment Advisers Act or the CEA.

The Sponsor arranged for the creation of the Trust and, following their uplisting on February 18, 2026, listing of the Shares on NYSE Arca (the Shares were previously quoted on OTCQB). As partial consideration for its receipt of the Sponsor’s Fee from the Trust, the Sponsor is obligated to pay the Sponsor-paid Expenses. The Sponsor also paid the costs of the Trust’s organization and the costs of the initial sale of the Shares.

The Sponsor is generally responsible for the day-to-day administration of the Trust under the provisions of the Trust Agreement. This includes (i) preparing and providing periodic reports and financial statements on behalf of the Trust for investors, (ii) processing orders to create Baskets and coordinating the processing of such orders with the Custodian and the Transfer Agent, (iii) calculating and publishing the NAV and the NAV per Share of the Trust each business day as of 4:00 p.m., New York time, or as soon thereafter as practicable, (iv) selecting and monitoring the Trust’s service providers and from time to time engaging additional, successor or replacement service providers, (v) instructing the Custodian to transfer the Trust’s SUI, as needed to pay the Sponsor’s Fee and any Additional Trust Expenses, (vi) upon dissolution of the Trust, distributing the Trust’s remaining SUI or the cash proceeds of the sale thereof to the owners of record of the Shares and (vii) establishing the principal market for U.S. GAAP valuation. In addition, if there is a fork in the Sui Network after which there is a dispute as to which network resulting from the fork is the Sui Network, the Sponsor has the authority to select the network that it believes in good faith is the Sui Network, unless such selection or authority would otherwise conflict with the Trust Agreement.

The Sponsor does not store, hold, or maintain custody or control of the Trust’s SUI but instead has entered into the Prime Broker Agreement with the Custodian to facilitate the security of the Trust’s SUI.

The Sponsor may transfer all or substantially all of its assets to an entity that carries on the business of the Sponsor if at the time of the transfer the successor assumes all of the obligations of the Sponsor under the Trust Agreement. In such an event, the Sponsor will be relieved of all further liability under the Trust Agreement.

The Sponsor’s Fee is paid by the Trust to the Sponsor as compensation for services performed under the Trust Agreement and as partial consideration for the Sponsor’s agreement to pay the Sponsor-paid Expenses. See “—Expenses; Sales of SUI.”

The Sponsor may, in its sole discretion, select a different index provider, select a different index price provided by the Index Provider, calculate the Index Price by using the cascading set of rules set forth under “—Overview of the Sui Industry and Market—SUI Value—The Index and the Index Price—Determination of the Index Price When Index Price is Unavailable” above, or change the cascading set of rules set forth above at any time.

Marketing Agent Agreement

The Sponsor, on behalf of the Trust, is party to a marketing agent agreement dated October 22, 2025 (the “Marketing Agent Agreement”) with Foreside Fund Services, LLC (the “Marketing Agent” or “Foreside”). Under the Marketing Agent Agreement, the Marketing Agent will provide the following services to the Sponsor: (i) assist the Sponsor in facilitating Participant Agreements between and among Authorized Participants, the Sponsor, on behalf of the Trust, and the Transfer Agent; (ii) provide prospectuses to Authorized Participants; (iii) work with the Transfer Agent to review and approve orders placed by the Authorized Participants and transmitted to the Transfer Agent; (iv) review and file applicable marketing materials with FINRA and (v) maintain, reproduce and store applicable books and records related to the services provided under the Marketing Agent Agreement. The Sponsor will pay the Marketing Agent an annual fee, as well as certain out-of-pocket fees and expenses of the Marketing Agent incurred in connection with its assistance in the marketing of the Trust and its Shares.

As of February 18, 2026, the Sponsor amended, solely with respect to the Trust, the Distribution and Marketing Agreement, dated as of August 1, 2024, among the Sponsor, the Trust and Grayscale Securities, LLC (“Grayscale Securities”), an affiliate of the Sponsor and an affiliate and related party of the Trust, to remove the Trust as an entity covered by the Distribution and Marketing Agreement. In its capacity as distributor and marketer, Grayscale Securities assisted the Sponsor in developing an ongoing marketing plan for the Trust, preparing marketing materials regarding the Shares, including the content on the Trust’s website, and executing the marketing plan for the Trust.

Index License Agreement

The Sponsor has entered into the Index License Agreement with CoinDesk Indices, Inc., the Index Provider, governing the Sponsor’s use of the Index for calculation of the Index Price. The Index Provider may adjust the calculation methodology for the Index without notice to, or consent of, the Trust or its shareholders. Under the Index License Agreement, the Sponsor pays a monthly fee and a fee based on the NAV of the Trust to the Index Provider in consideration of its license to the Sponsor of Index-related intellectual property. The initial term of the Index License Agreement was February 1, 2022 through the later of February 29, 2024 and the latest date set forth on any order form executed under the Index License Agreement. On June 20, 2023, the Sponsor and the Index Provider, entered into an amendment to the Index License Agreement to extend the initial term of the Index License Agreement from February 29, 2024, to February 28, 2025. On February 5, 2025, the Sponsor and the Index Provider, entered into an amendment to the Index License Agreement to extend the term of the Index License Agreement from February 28, 2025, to February 29, 2028. Thereafter, the Index License Agreement will automatically renew on an annual basis, unless a notice of non-renewal is provided. The Index License Agreement is terminable by either party upon written notice in the event of a material breach that remains uncured for thirty days after initial written notice of such breach. Further, either party may terminate the Index License Agreement immediately upon notice under certain circumstances, including with respect to the other party’s (i) insolvency, bankruptcy or analogous event or (ii) violation of money transmission, taxation or trading regulations that materially adversely affect either party’s ability to perform under the Index License Agreement.

The Trust issues Shares to, and redeems Shares from, Authorized Participants on an ongoing basis, but only in one or more Baskets (with a “Basket” being a block of 10,000 Shares). See “—Description of Creation and Redemption of Shares.”

As of the date of this filing, NYSE Arca has received regulatory approval permitting the Trust to conduct creations and redemptions of Shares via in-kind transactions with Authorized Participants or AP Designees in exchange for SUI. The Trust is also able to accept Cash Orders (as defined herein). Accordingly, the Trust is permitted to conduct creations and redemptions of Shares

pursuant to In-Kind Orders and Cash Orders (each as described herein). See “Item 1A. Risk Factors—Risk Factors Related to the Trust and the Shares—The limited ability to facilitate in-kind creations and redemptions of Shares could have adverse consequences for the Trust” for more information.

As of the date of this Annual Report, the Sponsor, on behalf of the Trust, and the Transfer Agent entered into Participant Agreements with Jane Street Capital, LLC and Virtu Americas LLC, pursuant to which such entities have agreed to act as Authorized Participants. The Sponsor may engage additional Authorized Participants who are unaffiliated with the Trust in the future.

No Authorized Participant has any obligation or responsibility to the Sponsor or the Trust to effect any sale or resale of Shares.

Liquidity Providers

Liquidity Providers facilitate the purchase and sale of SUI in connection with Cash Orders for creations or redemptions of Baskets. The Liquidity Providers with which Grayscale Investments Sponsors, LLC, (in such capacity, the “Liquidity Engager”), will engage in SUI transactions are third parties that are not affiliated with the Sponsor or the Trust and are not acting as agents of the Trust, the Sponsor, or any Authorized Participant. Except for the contractual relationships between each Liquidity Provider and Grayscale Investments Sponsors, LLC in its capacity as the Liquidity Engager, there is no contractual relationship between each Liquidity Provider and the Trust, the Sponsor, or any Authorized Participant.

As of the date of this Annual Report, the Liquidity Engager has engaged JSCT, LLC, Virtu Financial Singapore Pte. Ltd., Flow Traders B.V., Flowdesk, Cumberland DRW LLC, and Galaxy Digital Trading Cayman LLC as Liquidity Providers. The Liquidity Engager may engage additional Liquidity Providers who are unaffiliated with the Trust in the future.

Jane Street Capital, LLC, one of the Authorized Participants, is an affiliate of JSCT, LLC, one of the Liquidity Providers. Virtu Americas LLC, one of the Authorized Participants, is an affiliate of Virtu Financial Singapore Pte., Ltd, one of the Liquidity Providers.

The Custodian and Prime Broker

Coinbase Custody Trust Company, LLC is a fiduciary under § 100 of the New York Banking Law and a qualified custodian for purposes of Rule 206(4)-2(d)(6) under the Investment Advisers Act. The Custodian is authorized to serve as the Trust’s custodian under the Trust Agreement and pursuant to the terms and provisions of the Prime Broker Agreement. The Custodian has its principal office at 200 Park Avenue South, Suite 1208, New York, NY 10003. A copy of the Prime Broker Agreement is available for inspection at the Sponsor’s principal office identified herein.

Under the Prime Broker Agreement, the Custodian controls and secures the Trust’s “Vault Balance,” a segregated custody account to store private keys, which allow for the transfer of ownership or control of the Trust’s SUI, on the Trust’s behalf. The Custodian’s services (i) allow SUI to be deposited from a public blockchain address to the Trust’s Vault Balance and (ii) allow the Trust or Sponsor to withdraw SUI from the Trust’s Vault Balance to a public blockchain address the Trust or Sponsor controls (the “Custodial and Prime Broker Services”). Pursuant to the addendum to the Coinbase Custody Custodial Services Agreement attached as Exhibit A to the Coinbase Prime Broker Agreement, the Sponsor has caused, and from time to time may cause, the Trust to enter into Staking Arrangements with the Custodian and one or more Staking Providers, which may be affiliates of the Custodian or other trusted institutional validators, to stake the Trust’s SUI via Provider-Facilitated Staking. The Sponsor anticipates that the Trust’s SUI is and will be staked exclusively by means of Provider-Facilitated Staking.

The Vault Balance uses offline storage, or “cold” storage, mechanisms to secure the Trust’s private keys. The term cold storage refers to a safeguarding method by which the private keys corresponding to digital assets are disconnected.

The Custodian will withdraw from the Trust’s Vault Balance the amount of SUI necessary to pay the Trust’s expenses.

Fees paid to the Custodian are a Sponsor-paid Expense.

Under the Prime Broker Agreement, each of the Custodian and the Trust has agreed to indemnify and hold harmless the other party from any third-party claim or third-party demand (including reasonable and documented attorneys’ fees and any fines, fees or penalties imposed by any regulatory authority) arising out of or related to the Custodian’s or the Trust’s, as the case may be, breach of the Prime Broker Agreement, inaccuracy in any of the Custodian’s or the Trust’s, as the case may be, representations or warranties in the Prime Broker Agreement, or the Trust’s violation, or the Custodian’s knowing violation, of any law, rule or regulation, or the rights of any third party, except where such claim directly results from the negligence, fraud or willful misconduct of the other such party. In addition, the Trust has agreed to indemnify the Custodian with respect to any Incidental Rights or IR Virtual Currency abandoned by the Trust and any tax liability relating thereto or arising therefrom.

The Custodian and its affiliates may from time to time purchase or sell SUI for their own accounts and as agent for their customers or Shares for their own accounts. The foregoing notwithstanding, SUI in the Vault Balance are not treated as general assets of the Custodian and cannot be commingled with any other digital assets held by the Custodian. The Custodian serves as a fiduciary and custodian on the Trust’s behalf, and the SUI in the Vault Balance are considered fiduciary assets that remain the Trust’s property at all times.

Once each calendar year, the Sponsor or the Trust may request that the Custodian deliver a certificate signed by a duly authorized officer to certify that all representations and warranties made by the Custodian in the Prime Broker Agreement are true and correct on and as of the date of such certificate, and have been true and correct throughout the preceding year. In addition, the Custodian has agreed to allow the Trust and the Sponsor to take any necessary steps to verify that satisfactory internal control system and procedures are in place, and to visit and inspect the systems on which the Custodian’s coins are held.

If the Custodian resigns in its capacity as custodian, the Sponsor may appoint an additional or replacement custodian and enter into a custodian agreement on behalf of the Trust with such custodian. Furthermore, the Sponsor and the Trust may use SUI custody services or similar services provided by entities other than Coinbase Custody Trust Company, LLC at any time without prior notice to Coinbase Custody Trust Company, LLC.

Custody of the Trust’s SUI

Digital assets and digital asset transactions are recorded and validated on blockchains, the public transaction ledgers of a digital asset network. Each digital asset blockchain serves as a record of ownership for all of the units of such digital asset, even in the case of certain privacy-preserving digital assets, where the transactions themselves are not publicly viewable. All digital assets recorded on a blockchain are associated with a public blockchain address, also referred to as a digital wallet. Digital assets held at a particular public blockchain address may be accessed and transferred using a corresponding private key.

Key Generation

Public addresses and their corresponding private keys are generated by the Custodian in secret key generation ceremonies at secure locations inside faraday cages, which are enclosures used to block electromagnetic fields and thus mitigate against attacks. The Custodian uses quantum random number generators to generate the public and private key pairs.

Once generated, private keys are encrypted, separated into “shards”, and then further encrypted. After the key generation ceremony, all materials used to generate private keys, including computers, are destroyed. All key generation ceremonies are performed offline. No party other than the Custodian has access to the private key shards of the Trust, including the Trust itself.

Key Storage

Private key shards are distributed geographically by the Prime Broker and the Custodian (together, the “Custodial Entities”) in secure vaults around the world, including in the United States. The locations of the secure vaults may change regularly and are kept confidential by the Custodian and the Prime Broker for security purposes.

The Vault Balance primarily uses “cold” storage mechanisms to secure a substantial portion of the Trust’s private keys. A substantial portion of the Trust’s SUI holdings are held in cold storage at all times, with a portion of the Settlement Balance held temporarily in hot storage from time to time, for purposes of facilitating the receipt and distribution of SUI in connection with the creation and redemption of Baskets. Any SUI credited to the Trust’s Settlement Balance is stored in omnibus accounts, either on the Prime Broker’s systems or at Coinbase Connected Venues, using a combination of cold and hot storage mechanisms to secure the private keys representing the assets credited to the Trust’s Settlement Balance.

Cold storage is a safeguarding method with multiple layers of protections and protocols, by which the private keys corresponding to the Trust’s SUI are generated and stored in an offline manner. A digital wallet may receive deposits of digital assets but may not send digital assets without use of the digital assets’ corresponding private keys. In order to send digital assets from a digital wallet in which the private keys are kept in cold storage, either the private keys must be retrieved from cold storage and entered into an online, or “hot”, digital asset software program to sign the transaction, or the unsigned transaction must be transferred to the cold server in which the private keys are held for signature by the private keys and then transferred back to the online digital asset software program. At that point, the user of the digital wallet can transfer its digital assets. While private keys held in hot storage are more accessible and therefore enable more efficient transfers, such assets are more vulnerable to theft, loss or damage.

Security Procedures

The Custodian and the Prime Broker hold the Trust’s private keys in custody in accordance with the terms and provisions of the Prime Broker Agreement. Transfers to and from the Vault Balance and, where held in cold storage, the Trust’s Settlement Balance, require certain security procedures, including but not limited to, multiple encrypted private key shards, usernames, passwords and 2-step verification. Multiple private key shards held by the applicable Custodial Entity or Entities must be combined to reconstitute the private key to sign any transaction in order to transfer the Trust’s assets. Private key shards are distributed geographically by the Custodial Entities in secure vaults around the world, including in the United States.

As a result, if any one secure vault is ever compromised, this event will have no impact on the ability of the Trust to access its assets, other than a possible delay in operations, while one or more of the other secure vaults is used instead. These security procedures are intended to remove single points of failure in the protection of the Trust’s assets.

Transfers of SUI to the Vault Balance from the Settlement Balance will be available to the Trust once processed on the Blockchain, subject to the availability of the Prime Broker’s online platform. When SUI is credited to the Settlement Balance, certain movements to allocate the balance among (i) omnibus cold storage wallets and omnibus hot storage wallets on the Prime Broker’s platform; or (ii) omnibus accounts at Coinbase Connected Venues may not be viewable by the Trust via the Prime Broker’s online portal. In addition, on a monthly basis the Custodial Entities will provide the Sponsor with an account statement identifying the amount of cash and SUI in the Trust’s Accounts at the end of the period and listing all account activity during that period.

The process of accessing and withdrawing SUI from the Trust to redeem a Basket by an Authorized Participant follows the same general procedure as transferring SUI to the Trust to create a Basket by an Authorized Participant, only in reverse. See “—Description of Creation and Redemption of Shares.”

The Marketing Agent

Prior to February 18, 2026, Grayscale Securities was the distributor and marketer of the Shares. Since February 18, 2026, Foreside Fund Services, LLC (“Foreside”) is the marketing agent of the Shares, and Grayscale Securities ceased acting as the distributor and marketer of the Shares of the Trust. Foreside is a registered broker-dealer with the SEC and is a member of FINRA.

In its capacity as marketing agent, Foreside provides the following services to the Sponsor: (i) assist the Sponsor in facilitating Participant Agreements between and among Authorized Participants, the Sponsor, on behalf of the Trust, and the Transfer Agent; (ii) provide prospectuses to Authorized Participants; (iii) work with the Transfer Agent to review and approve orders placed by the Authorized Participants and transmitted to the Transfer Agent; (iv) review and file applicable marketing materials with FINRA and (v) maintain, reproduce and store applicable books and records related to the services provided under the Marketing Agent Agreement.

The Sponsor has entered into a Marketing Agent Agreement with Foreside. The Sponsor may engage additional or successor marketing agents in the future.

Description of the Shares

The Trust is authorized under the Trust Agreement to create and issue an unlimited number of Shares. Shares will be issued only in Baskets (a Basket equals a block of 10,000 Shares) in connection with creations. The Shares represent units of fractional undivided beneficial interest in and ownership of the Trust and have no par value. The Shares are listed on NYSE Arca under the ticker symbol “GSUI.”

Description of Limited Rights

The Shares do not represent a traditional investment and should not be viewed as similar to “shares” of a corporation operating a business enterprise with management and a board of directors. A shareholder will not have the statutory rights normally associated with the ownership of shares of a corporation. Each Share is transferable, is fully paid and non-assessable and entitles the holder to vote on the limited matters upon which shareholders may vote under the Trust Agreement. For example, shareholders do not have the right to elect or remove directors and will not receive dividends. The Shares do not entitle their holders to any conversion or pre-emptive rights or, except as discussed below, any redemption rights or rights to distributions.

Voting and Approvals

The shareholders take no part in the management or control of the Trust. Under the Trust Agreement, shareholders have limited voting rights. For example, in the event that the Sponsor withdraws, a majority of the shareholders may elect and appoint a successor sponsor to carry out the affairs of the Trust. The Sponsor is also permitted to make certain restatements, amendments or supplements to the Trust Agreement that would materially adversely affect the interests of the shareholders as determined by the Sponsor in its sole discretion with a 20-day notice to shareholders. Additionally, the Sponsor is permitted to make certain restatements, amendments or supplements to the Trust Agreement that could adversely affect the status of the Trust as a grantor trust for U.S. federal income tax purposes, but only if certain conditions set forth in the amendments relating to the qualification of the Trust as a grantor trust for U.S. federal income tax purposes are satisfied. Furthermore, subject to certain limitations, the Sponsor may make any other amendments to the Trust Agreement which do not materially adversely affect the interests of the shareholders in its sole discretion without shareholder consent.

Distributions

Pursuant to the terms of the Trust Agreement, the Trust may make distributions on the Shares in-cash or in-kind. In addition, if the Trust is terminated and liquidated, the Sponsor will distribute to the shareholders any amounts of the cash proceeds of the liquidation remaining after the satisfaction of all outstanding liabilities of the Trust and the establishment of reserves for applicable taxes, other governmental charges and contingent or future liabilities as the Sponsor will determine. See “—Description of the Trust Agreement—Termination of the Trust.” Shareholders of record on the record date fixed by the Transfer Agent for a distribution will be entitled to receive their pro rata portions of any distribution.

Creation of Shares

The Trust creates Shares at such times and for such periods as determined by the Sponsor, but only in one or more whole Baskets. A Basket equals 10,000 Shares. See “—Description of Creation and Redemption of Shares.” The creation of a Basket requires the delivery to the Trust of the amount of SUI (or cash to acquire the amount of SUI) represented by one Share immediately prior to such creation multiplied by 10,000. The Trust may from time to time halt creations, including for extended periods of time, for a variety of reasons, including in connection with forks, airdrops and other similar occurrences.

Redemption of Shares

On September 17, 2025, the SEC approved the Generic Listing Standards. On February 17, 2026, NYSE Arca certified its approval for listing and trading of the Shares of the Trust under the Generic Listing Standards and registration of the Shares under the Exchange Act. Shares of the Trust began trading on NYSE Arca under the symbol “GSUI” on February 18, 2026. In connection with the listing of the Shares, the Sponsor authorized the commencement of the Trust’s redemption program in reliance on Regulation M exemptive relief available to similarly situated commodity-based exchange-traded products.

Shares are redeemable only in accordance with the provisions of the Trust Agreement and the relevant Participant Agreement. Through its redemption program, the Trust redeems Shares from Authorized Participants on an ongoing basis. Although the Trust redeems Baskets by distributing SUI or proceeds from the disposition of SUI, an Authorized Participant may submit either In-Kind Orders or Cash Orders. In a Cash Order, the Authorized Participant will accept cash from the Cash Account (as defined herein) in connection with the redemption of Baskets. In an In-Kind Order, the Authorized Participant or its AP Designee will receive SUI directly from the Trust in connection with the redemption of Baskets.

Cash Orders are facilitated by the Transfer Agent and Grayscale Investments Sponsors, LLC, which acts on behalf of the Trust in its capacity as Liquidity Engager and will engage one or more Liquidity Providers that is not an agent of, or otherwise acting on behalf of, any Authorized Participant receiving SUI in connection with such orders. See “Description of Creation and Redemption of Shares.”

The Sponsor may suspend the Trust’s redemption program in its sole discretion, or the redemption program may otherwise become unavailable, which could cause the Shares to trade at a discount to the NAV per Share. See “Item 1A. Risk Factors—Risk Factors Related to the Trust and the Shares—The limited ability to facilitate in-kind creations and redemptions of Shares could have adverse consequences for the Trust.”

Book-Entry Form

Shares are held primarily in book-entry form by the Transfer Agent. The Sponsor or its delegate will direct the Transfer Agent to credit or debit, as applicable, the number of Baskets to the applicable Authorized Participant. The Transfer Agent will issue or cancel Baskets, as applicable. Transfers will be made in accordance with standard securities industry practice. The Sponsor may cause the Trust to issue Shares in certificated form in limited circumstances in its sole discretion.

Share Splits

In its discretion, the Sponsor may direct the Transfer Agent to declare a split or reverse split in the number of Shares outstanding and to make a corresponding change in the number of Shares constituting a Basket. For example, if the Sponsor believes that the per Share price in the secondary market for Shares has risen or fallen outside a desirable trading price range, it may declare such a split or reverse split.

Description of Creation and Redemption of Shares

General

The Trust issues Shares to and redeems Shares from Authorized Participants on an ongoing basis, but only in one or more Baskets (with a “Basket” being a block of 10,000 Shares). The Trust will not issue fractions of a Basket. The Sponsor believes that the creation and redemption order size of 10,000 Shares will enable Authorized Participants to manage inventory and facilitate an effective arbitrage mechanism for the Trust. However, the Sponsor may in the future adjust the creation and redemption order size in order to improve the effectiveness of the activities of Authorized Participants in the secondary market for the Shares if the Sponsor determines it to be necessary or advisable. As such, the Sponsor does not expect that the size of the Baskets will have an impact on the arbitrage mechanism.

The creation and redemption of Baskets will be made only upon the delivery to the Trust, or the distribution or other disposition by the Trust, of the amount of whole and fractional SUI represented by each Basket being created or redeemed, which is determined by dividing (x) the amount of SUI owned by the Trust at 4:00 p.m., New York time, on the trade date of a creation or redemption order, after deducting the amount of SUI representing the U.S. dollar value of accrued but unpaid fees and expenses of the Trust (converted using the Index Price at such time, and carried to the eighth decimal place), by (y) the number of Shares outstanding at such time (with the quotient so obtained calculated to one one-hundred-millionth of one SUI (i.e., carried to the eighth decimal place)), and multiplying

such quotient by 10,000 (the “Basket Amount”). The U.S. dollar value of a Basket is calculated by multiplying the Basket Amount by the Index Price as of the trade date (the “Basket NAV”). The Basket NAV multiplied by the number of Baskets being created or redeemed is referred to as the “Total Basket NAV.” All questions as to the calculation of the Basket Amount will be conclusively determined by the Sponsor and will be final and binding on all persons interested in the Trust. One or more major market data vendors may provide an intra-day indicative value (“IIV”) per Share updated every 15 seconds, as calculated by NYSE Arca or a third-party financial data provider during NYSE Arca’s Core Trading Session (9:30 a.m. to 4:00 p.m., New York time). Such IIV will be calculated using the same methodology as the NAV per Share of the Trust, specifically by using the prior day’s closing NAV per Share as a base and updating that value during the NYSE Arca Core Trading Session to reflect changes in the value of the Trust’s NAV during the trading day. The IIV on a per Share basis disseminated during the Core Trading Session should not be viewed as a real-time update of the NAV, which is calculated once a day. The amount of SUI represented by a Share will gradually decrease over time as the Trust’s SUI are used to pay the Trust’s expenses.

Authorized Participants are the only persons that may place orders to create and redeem Baskets. Each Authorized Participant must (i) be a registered broker-dealer and (ii) enter into a Participant Agreement with the Sponsor and the Transfer Agent and (iii) in the case of any creation or redemption pursuant to In-Kind Orders, own a SUI wallet address that is known to the Custodian as belonging to the Authorized Participant (and maintain an account with the Custodian (or if the Authorized Participant does not itself trade in SUI, a designee of such Authorized Participant (each, an “AP Designee”) must own a SUI wallet address that is known to the Custodian as belonging to such AP Designee and maintain an account with the Custodian.

An Authorized Participant may act for its own account or as agent for broker-dealers, custodians and other securities market participants that wish to create or redeem Baskets. Shareholders who are not Authorized Participants will only be able to create or redeem their Shares through an Authorized Participant.

The creation of Baskets requires the delivery to the Trust of the Total Basket Amount (or cash to acquire the Total Basket Amount) and the redemption of Baskets requires the distribution or other disposition by the Trust of the Total Basket Amount. Although the Trust creates Baskets only upon the receipt of SUI, and redeems Baskets only by distributing SUI or proceeds from the disposition of SUI, at this time an Authorized Participant can only submit Cash Orders, pursuant to which the Authorized Participant will deposit cash into, or accept cash from, a segregated account maintained by the Transfer Agent in the name of the Trust for purposes of receiving and distributing cash in connection with the creation and redemption of Baskets (such account, the “Cash Account”).

Cash Orders will be facilitated by the Transfer Agent and Grayscale Investments Sponsors, LLC. On an order-by-order basis, Grayscale Investments Sponsors, LLC, acting in its capacity as Liquidity Engager will engage one or more Liquidity Providers to obtain or receive SUI in exchange for cash in connection with such order, as described in more detail below. Each Liquidity Provider must enter into a Liquidity Provider Agreement with the Liquidity Engager and the Sponsor (on behalf of the Trust), which will obligate it to obtain or receive SUI in connection with creations and redemptions pursuant to Cash Orders.

Unless the Sponsor requires that a Cash Order be effected at actual execution prices (an “Actual Execution Cash Order”), each Authorized Participant that submits a Cash Order to create or redeem Baskets will pay a fee (the “Variable Fee”) based on the Total Basket NAV (a “Variable Fee Cash Order”), and any price differential between (x) the Total Basket NAV on the trade date and (y) the price realized in acquiring or disposing of the corresponding Total Basket Amount, as the case may be, will be borne solely by the Liquidity Provider until such SUI have been received or liquidated by the Trust. The Variable Fee is intended to cover all of a Liquidity Provider’s expenses in connection with the creation or redemption order, including any exchange fees that the Liquidity Provider incurs in connection with buying or selling SUI. The amount may be changed by the Sponsor in its sole discretion at any time, and Liquidity Providers will communicate to the Sponsor in advance the Variable Fee they would be willing to accept in connection with a Variable Fee Cash Order, based on market conditions and other factors existing at the time of such Variable Fee Cash Order.

Alternatively, the Sponsor may require that a Cash Order be effected as an Actual Execution Cash Order, in its sole discretion based on market conditions and other factors existing at the time of such Cash Order, and under such circumstances, any price differential between (x) the Total Basket NAV on the trade date and (y) the price realized in acquiring or disposing of the corresponding Total Basket Amount, as the case may be, will be borne solely by such Authorized Participant until such SUI have been received or liquidated by the Trust. See “—Creation Procedures—Actual Execution Cash Orders” and “—Redemption Procedures—Actual Execution Cash Orders.”

In the case of creations pursuant to Cash Orders, to transfer the Total Basket Amount to the Trust’s Vault Balance, the Liquidity Provider will transfer SUI to one of the public key addresses associated with the Vault Balance and as provided by the Sponsor. In the case of redemptions pursuant to Cash Orders, the same procedure is conducted, but in reverse, using the public key addresses associated with the wallet of the Liquidity Provider, and as provided by such party. All such transactions will be conducted on the Blockchain and parties acknowledge and agree that such transfers may be irreversible if done incorrectly. See “Item 1A. Risk Factors—Risk Factors Related to the Trust and the Shares—Ether transactions are irrevocable and stolen or incorrectly transferred SUI may be irretrievable. As a result, any incorrectly executed SUI transactions could adversely affect the value of the Shares.”

The Trust may also create and redeem Baskets via In-Kind Orders, pursuant to which an Authorized Participant or its AP Designee will deposit SUI directly with the Trust or receive SUI directly from the Trust.

Authorized Participants do not pay a transaction fee to the Trust in connection with the creation or redemption of Baskets, but there may be transaction fees associated with the validation of the transfer of SUI by the Sui Network, which will be paid by the Custodian in the case of redemptions and an Authorized Participant, its AP Designee or the Liquidity Provider in the case of creations. Service providers may charge Authorized Participants or AP Designees administrative fees for order placement and other services related to the creation or redemption of Baskets. As discussed above, Authorized Participants will also pay the Variable Fee in connection with Variable Fee Cash Orders. As discussed in further detail below under “—Creation Procedures—Actual Execution Cash Orders” and “—Redemption Procedures—Actual Execution Cash Orders”, under certain circumstances Authorized Participants may also be required to deposit additional cash in the Cash Account, or be entitled to receive excess cash from the Cash Account, in connection with creations and redemptions pursuant to Actual Execution Cash Orders. Authorized Participants will receive no fees, commissions or other form of compensation or inducement of any kind from either the Sponsor or the Trust and no such person has any obligation or responsibility to the Sponsor or the Trust to effect any sale or resale of Shares.

The Participant Agreements and the related procedures attached thereto may be amended by the Sponsor and the relevant Authorized Participant. Under the Participant Agreements, the Sponsor has agreed to indemnify each Authorized Participant against certain liabilities, including liabilities under the Securities Act.

The following description of the procedures for the creation and redemption of Baskets is only a summary and shareholders should refer to the relevant provisions of the Trust Agreement and the form of Participant Agreement for more detail.

Creation Procedures

On any business day, an Authorized Participant may place an order with the Transfer Agent to create one or more Baskets. Orders for creations may be either In-Kind Orders or Cash Orders. In-Kind Orders for creation must be placed with the Transfer Agent no later than 3:59:59 p.m., New York time, and Cash Orders for creation must be placed with the Transfer Agent no later than 1:59:59 p.m., New York time (the “Order Cutoff Time”).

The Sponsor may in its sole discretion limit the number of Shares created pursuant to Cash Orders on any specified day without notice to the Authorized Participants and may direct the Marketing Agent to reject any Cash Orders in excess of such capped amount. In exercising its discretion to limit the number of Shares created pursuant to Cash Orders, the Sponsor expects to take into consideration a number of factors, including (i) the availability of Liquidity Providers to facilitate Cash Orders and (ii) the cost of processing Cash Orders relative to the cost of processing In-Kind Orders. If the Sponsor decides to limit Cash Orders and there are not otherwise a sufficient amount of In-Kind Orders to allow the arbitrage mechanism to function, or if the Trust is otherwise unable to satisfy creation orders made in cash, the Trust’s ability to create new Shares could be negatively impacted, which could impact the Shares’ liquidity and/or cause the Shares to trade at premiums to the NAV per Share, and otherwise have a negative impact on the value of the Shares. See “Item 1A. Risk Factors—Risk Factors Related to the Trust and the Shares—The limited ability to facilitate in-kind creations and redemptions of Shares could have adverse consequences for the Trust.”

In-Kind Orders

Creations pursuant to In-Kind Orders will take place as follows, where “T” is the trade date and each day in the sequence must be a business day.

      
Trade Date (T)

     Settlement Date 
(T+1, or T+2, as established at the time of order placement)

     •The Authorized Participant places a creation order with the Transfer Agent.
•The Marketing Agent accepts (or rejects) the creation order, which is communicated to the Authorized Participant by the Transfer Agent.

     •The Authorized Participant or AP Designee transfers the Total Basket Amount to the Trust’s Vault Balance.
•The Trust issues the aggregate number of Shares corresponding to the Baskets ordered by the Authorized Participant and the Transfer Agent delivers such Shares by crediting the number of Baskets created to the Authorized Participant’s DTC account.

Cash Orders

Creations pursuant to Cash Orders will take place as follows, where “T” is the trade date and each day in the sequence must be a business day. Before a creation pursuant to a Cash Order is placed, the Sponsor determines if such creation pursuant to a Cash Order

will be a Variable Fee Cash Order or an Actual Execution Cash Order, which determination is communicated to the Authorized Participant. The Trust began accepting cash orders following the uplisting of the Shares to NYSE Arca on February 18, 2026.

     Trade Date (T)

     Settlement Date 
(T+1, or T+2, as established at the time of order placement)

     •The Authorized Participant places a creation order with the Transfer Agent.
•The Marketing Agent accepts (or rejects) the creation order, which is communicated to the Authorized Participant by the Transfer Agent. 
•The Sponsor notifies the Liquidity Provider of the creation order. 
•The Sponsor determines the Total Basket NAV and any Variable Fee and Additional Creation Cash as soon as practicable after 4:00 p.m., New York time.

      

     •The Authorized Participant delivers to the Cash Account: 
(x) in the case of a Variable Fee Cash Order, the Total Basket NAV, plus any Variable Fee; or  
(y) in the case of an Actual Execution Cash Order, the Total Basket NAV, plus any Additional Creation Cash, less any Excess Creation Cash, if applicable (such amount, as applicable, the “Required Creation Cash”).  
•The Liquidity Provider transfers the Total Basket Amount to the Trust’s Vault Balance. 
•Once the Trust is in simultaneous possession of (x) the Total Basket Amount and (y) the Required Creation Cash, the Trust issues the aggregate number of Shares corresponding to the Baskets ordered by the Authorized Participant, which the Transfer Agent holds for the benefit of the Authorized Participant. 
•Cash equal to the Required Creation Cash is delivered to the Liquidity Provider from the Cash Account.
•The Transfer Agent delivers Shares to the Authorized Participant by crediting the number of Baskets created to the Authorized Participant’s DTC account.

    

Variable Fee Cash Orders

Unless the Sponsor determines otherwise in its sole discretion based on market conditions and other factors existing at the time of such Cash Order, all creations pursuant to Cash Orders are expected to be executed as Variable Fee Cash Orders, and any price differential between (x) the Total Basket NAV on the trade date and (y) the price realized in acquiring the corresponding Total Basket Amount will be borne solely by the Liquidity Provider until such SUI have been received by the Trust.

The Sponsor anticipates that the Trust’s cost to acquire the Total Basket Amount in connection with a Variable Fee Cash Order will equal the sum of the corresponding Total Basket NAV and Variable Fee to be delivered by the Authorized Participant to the Trust. In the event that, by 12:00 p.m., New York time on the settlement date of a creation pursuant to a Variable Fee Cash Order, either (x) the Trust’s Vault Balance has not been credited with SUI in an amount equal to the Total Basket Amount or (y) the Cash Account has not been credited with the Total Basket NAV, plus any Variable Fee, such Cash Order will be deemed a failed trade, with any consideration that has been delivered by the Authorized Participant or the Liquidity Provider in respect of such Cash Order being returned by the Trust.

The Transfer Agent shall under no circumstances cause the Trust to issue Shares in respect of a Variable Fee Cash Order until such time as each of (x) the Total Basket Amount and (y) the Total Basket NAV, plus any Variable Fee, has been delivered to the Trust, and the Trust is in simultaneous possession of both.

Actual Execution Cash Orders

With respect to a creation pursuant to an Actual Execution Cash Order, as between the Trust and an Authorized Participant, the Authorized Participant is responsible for the dollar cost of the difference between the SUI price utilized in calculating Total Basket NAV on the trade date and the price at which the Trust acquires the SUI on the settlement date. If the price realized in acquiring the

corresponding Total Basket Amount is higher than the Total Basket NAV, the Authorized Participant will bear the dollar cost of such difference by delivering cash in the amount of such difference (the “Additional Creation Cash”) to the Cash Account. If the price realized in acquiring the corresponding Total Basket Amount is lower than the Total Basket NAV, the Authorized Participant will benefit from such difference, with the Trust promptly returning cash in the amount of such excess (the “Excess Creation Cash”) to the Authorized Participant.

In the event that, by 12:00 p.m., New York time on the settlement date of a creation pursuant to an Actual Execution Cash Order, either (x) the Trust’s Vault Balance has not been credited with SUI in an amount equal to the Total Basket Amount or (y) the Cash Account has not been credited with the Total Basket NAV (net of any Additional Creation Cash or Excess Creation Cash, if applicable), such Cash Order will be deemed a failed trade, with any consideration that has been delivered by the Authorized Participant or the Liquidity Provider in respect of such Cash Order being returned by the Trust.

The Transfer Agent shall under no circumstances cause the Trust to issue Shares in respect of a Cash Order until such time as each of (x) the Total Basket Amount and (y) the Total Basket NAV (net of any Additional Creation Cash or Excess Creation Cash, if applicable) has been delivered to the Trust, and the Trust is in simultaneous possession of both.

Redemption Procedures

The procedures by which an Authorized Participant can redeem one or more Baskets mirror the procedures for the creation of Baskets. On any business day, an Authorized Participant may place a redemption order specifying the number of Baskets to be redeemed. Redemption orders may be placed as either In-Kind Orders or Cash Orders, as described below. Orders for redemptions may be either In-Kind Orders or Cash Orders. In-Kind Orders for redemption must be placed with the Transfer Agent no later than 3:59:59 p.m., New York time, and Cash Orders for redemption must be placed with the Transfer Agent no later than 1:59:59 p.m., New York time. The Trust began accepting redemption orders following the uplisting of the Shares to NYSE Arca on February 18, 2026.

The redemption of Shares pursuant to Cash Orders will only take place if approved by the Sponsor in writing, in its sole discretion and on a case-by-case basis. In exercising its discretion to approve the redemption of Shares pursuant to Cash Orders, the Sponsor expects to take into consideration a number of factors, including (i) the availability of Liquidity Providers to facilitate Cash Orders and (ii) the cost of processing Cash Orders relative to the cost of processing In-Kind Orders. If the Sponsor decides to limit Cash Orders and there are not otherwise In-Kind Orders sufficient to allow the arbitrage mechanism to function, or if the Trust is unable to satisfy redemption orders made in cash, the Trust’s ability to redeem new Shares could be negatively impacted, which could impact the Shares’ liquidity and/or cause the Shares to trade at discounts, and could have a negative impact on the value of the Shares. See “Item 1A. Risk Factors—Risk Factors Related to the Trust and the Shares—The limited ability to facilitate in-kind creations and redemptions of Shares could have adverse consequences for the Trust” for more information.

The Authorized Participants may only redeem Baskets and cannot redeem any Shares in an amount less than a Basket.

In-Kind Orders

Redemptions pursuant to In-Kind Orders will take place as follows, where “T” is the trade date and each day in the sequence must be a business day.

      
Trade Date (T)

     Settlement Date 
(T+1, or T+2 as established at the time of order placement)

     •The Authorized Participant places a redemption order with the Transfer Agent.
•The Marketing Agent accepts (or rejects) the redemption order, which is communicated to the Authorized Participant by the Transfer Agent.

     •The Authorized Participant delivers Baskets to be redeemed from its DTC account to the Transfer Agent.
•The Custodian transfers the Total Basket Amount to the Authorized Participant or AP Designee, and the Transfer Agent cancels the Shares.

Cash Orders

Redemptions pursuant to Cash Orders will take place as follows, where “T” is the trade date and each day in the sequence must be a business day. Before a redemption pursuant to a Cash Order is placed, the Sponsor determines if such redemption order will be a Variable Fee Cash Order or an Actual Execution Cash Order, which determination is communicated to the Authorized Participant. The Trust began accepting cash orders following the uplisting of the Shares to NYSE Arca on February 18, 2026.

     Trade Date (T)

     Settlement Date 
(T+1, or T+2 as established at the time of order placement)

     •The Authorized Participant places a redemption order with the Transfer Agent.
•The Marketing Agent accepts (or rejects) the redemption order, which is communicated to the Authorized Participant by the Transfer Agent.
•The Sponsor notifies the Liquidity Provider of the redemption order.
•The Sponsor determines the Total Basket NAV and, in the case of a Variable Fee Cash Order, any Variable Fee, as soon as practicable after 4:00 p.m., New York time.

      

     •The Authorized Participant delivers Baskets to be redeemed from its DTC account to the Transfer Agent.
•The Liquidity Provider delivers to the Cash Account:
(x) in the case of a Variable Fee Cash Order, the Total Basket NAV less any Variable Fee; or 
(y) in the case of an Actual Execution Cash Order, the actual proceeds to the Trust from the liquidation of the Total Basket Amount (such amount, as applicable, the “Required Redemption Cash”). 
•Once the Trust is in simultaneous possession of (x) the Total Basket Amount and (y) the Required Redemption Cash, the Transfer Agent cancels the Shares comprising the number of Baskets redeemed by the Authorized Participant.
•The Custodian sends the Liquidity Provider the Total Basket Amount, and cash equal to the Required Redemption Cash is delivered to the Authorized Participant from the Cash Account.

    

Variable Fee Cash Orders

Unless the Sponsor determines otherwise in its sole discretion based on market conditions and other factors existing at the time of such Cash Order, all redemptions pursuant to Cash Orders are expected to be executed as Variable Fee Cash Orders, and any price differential between (x) the Total Basket NAV on the trade date and (y) the price realized in disposing of the corresponding Total Basket Amount will be borne solely by the Liquidity Provider.

The Sponsor anticipates that the Trust’s proceeds from liquidating the Total Basket Amount in connection with a Variable Fee Cash Order will equal the corresponding Total Basket NAV less the Variable Fee to be delivered by the Liquidity Provider to the Trust. In the event that, by 12:00 p.m. (New York time) on the settlement date of a redemption pursuant to a Variable Fee Cash Order, either (x) the Transfer Agent’s account at DTC has not been credited with the total number of Shares corresponding to the total number of Baskets to be redeemed or (y) the Cash Account has not been credited with the Total Basket NAV, less any Variable Fee, such Cash Order will be deemed a failed trade, with any consideration that has been delivered by the Authorized Participant or the Liquidity Provider in respect of such Cash Order being returned by the Trust.

The Transfer Agent shall under no circumstances deliver the Required Redemption Cash to the Authorized Participant in respect of a Variable Fee Cash Order until such time as (x) the Baskets to be redeemed have been delivered to the Transfer Agent and (y) the Total Basket NAV, less any Variable Fee, has been delivered to the Cash Account, and the Trust and/or the Transfer Agent is in simultaneous possession of both.

Actual Execution Cash Orders

With respect to a redemption pursuant to an Actual Execution Cash Order, as between the Trust and an Authorized Participant, the Authorized Participant is responsible for the dollar cost of the difference between the SUI price utilized in calculating Total Basket NAV on the trade date and the price at which the Trust disposes of the SUI on the settlement date. If the price realized in disposing the corresponding Total Basket Amount on the settlement date is lower than the Total Basket NAV on the trade date, the Authorized Participant will bear the dollar cost of such difference (the “Redemption Cash Shortfall”), with the amount of cash to be delivered to the Authorized Participant being reduced by the amount of such Redemption Cash Shortfall. If the price realized in disposing the corresponding Total Basket Amount on the settlement date is higher than the Total Basket NAV on the trade date, the Trust will deliver cash in the amount of such excess (the “Additional Redemption Cash”) to the Authorized Participant.

In the event that, by 12:00 p.m. (New York time) on the settlement date of a redemption pursuant to an Actual Execution Cash Order, either (x) the Transfer Agent’s account at DTC has not been credited with the total number of Shares corresponding to the total number of Baskets to be redeemed or (y) the Cash Account has not been credited with the Total Basket NAV (plus any Additional Redemption Cash or net of any Redemption Cash Shortfall), such Cash Order will be deemed a failed trade, with any consideration that has been delivered by the Authorized Participant or the Liquidity Provider in respect of such Cash Order being returned by the Trust.

The Transfer Agent shall under no circumstances deliver the Required Redemption Cash to the Authorized Participant in respect of a Cash Order until such time as (x) the Total Basket Amount has been delivered to the Transfer Agent and (y) the Total Basket NAV (plus any Additional Redemption Cash or net of any Redemption Cash Shortfall, if applicable) has been delivered to the Trust, and the Trust and/or the Transfer Agent is in simultaneous possession of both.

Suspension or Rejection of Orders and Total Basket Amount

The creation or redemption of Shares may be suspended generally, or refused with respect to particular requested creations or redemptions, during any period when the transfer books of the Transfer Agent are closed or if circumstances outside the control of the Sponsor or its delegates make it for all practical purposes not feasible to process creation orders or redemption orders or for any other reason at any time or from time to time. The Marketing Agent may reject an order or, after accepting an order, may cancel such order, if: (i) such order is not presented in proper form as described in the Participant Agreement, (ii) in the case of In-Kind Orders, the transfer of the Total Basket Amount comes from an account other than a SUI wallet address that is known to the Custodian as belonging to the Authorized Participant or its AP Designee or (iii) the fulfillment of the order, in the opinion of counsel, might be unlawful, among other reasons. None of the Sponsor or its delegates will be liable for the suspension, rejection or acceptance of any creation order or redemption order.

The Sponsor will notify investors of any suspension of creations or redemptions of Shares by filing a current report on Form 8-K. Suspension of the creation or redemption of Shares could negatively impact the Shares’ liquidity and/or cause the Shares to trade at premiums and discounts, and otherwise have a negative impact on the value of the Shares.

Tax Responsibility

Authorized Participants are responsible for any transfer tax, sales or use tax, stamp tax, recording tax, value-added tax or similar tax or governmental charge applicable to the creation and redemption of Baskets, regardless of whether such tax or charge is imposed directly on the Authorized Participants, and agree to indemnify the Sponsor and the Trust if the Sponsor or the Trust is required by law to pay any such tax, together with any applicable penalties, additions to tax or interest thereon.

Valuation of SUI and Determination of NAV

The Sponsor will evaluate the SUI held by the Trust and determine the NAV of the Trust in accordance with the relevant provisions of the Trust Documents. The following is a description of the material terms of the Trust Documents as they relate to valuation of the Trust’s SUI and the NAV calculations, which is calculated using non-GAAP methodology and is not used in the Trust’s financial statements.

On each business day at 4:00 p.m., New York time, or as soon thereafter as practicable (the “Evaluation Time”), the Sponsor will evaluate the SUI held by the Trust and calculate and publish the NAV of the Trust. To calculate the NAV, the Sponsor will:

Determine the Index Price as of such business day.

Multiply the Index Price by the Trust’s aggregate amount of SUI owned by the Trust as of 4:00 p.m., New York time, on the immediately preceding day, less the aggregate amount of SUI payable as the accrued and unpaid Sponsor’s Fee and Sponsor’s Staking Fee as of 4:00 p.m., New York time, on the immediately preceding day.

Add the U.S. dollar value of SUI, calculated using the Index Price, receivable under pending creation orders, if any, determined by multiplying the number of the Creation Baskets represented by such creation orders by the Basket Amount and then multiplying such product by the Index Price.

Subtract the U.S. dollar amount of accrued and unpaid Additional Trust Expenses, if any.

Subtract the U.S. dollar value of the SUI, calculated using the Index Price, which are either (i) to be distributed under pending redemption orders, if any, determined by multiplying the number of Baskets to be redeemed represented by such redemption orders by the Basket Amount and then multiplying such product by the Index Price, or (ii) to be distributed to shareholders pursuant to a binding obligation of the Trust following the declaration of an in-kind dividend (including through interests in any liquidating trust or other vehicle formed to hold such SUI) (the amount derived from steps 1 through 5 above, the “NAV Fee Basis Amount”).

Subtract the U.S. dollar amount of the Sponsor’s Fee that accrues for such business day, as calculated based on the NAV Fee Basis Amount for such business day.

In the event that the Sponsor determines that the primary methodology used to determine the Index Price is not an appropriate basis for valuation of the Trust’s SUI, the Sponsor will utilize the cascading set of rules as described in “—Overview of the Sui Industry and Market—SUI Value—The Index and the Index Price.”

The Sponsor will publish the Index Price, the Trust’s NAV and the NAV per Share on the Trust’s website as soon as practicable after its determination. If the NAV and NAV per Share have been calculated using a price per SUI other than the Index Price for such Evaluation Time, the publication on the Trust’s website will note the valuation methodology used and the price per SUI resulting from such calculation.

In the event of a hard fork of the Sui Network, the Sponsor will, if permitted by the terms of the Trust Agreement, use its discretion to determine, in good faith, which peer-to-peer network, among a group of incompatible forks of the Sui Network, is generally accepted as the network for SUI and should therefore be considered the appropriate network for the Trust’s purposes. The Sponsor will base its determination on a variety of then relevant factors, including (but not limited to) the following: (i) the Sponsor’s beliefs regarding expectations of the core developers of SUI, users, services, businesses, validators and other constituencies and (ii) the actual continued acceptance of, validating power on, and community engagement with the Sui Network.

The shareholders may rely on any evaluation furnished by the Sponsor. The determinations that the Sponsor makes will be made in good faith upon the basis of, and the Sponsor will not be liable for any errors contained in, information reasonably available to it. The Sponsor will not be liable to the Authorized Participants, the shareholders or any other person for errors in judgment. However, the preceding liability exclusion will not protect the Sponsor against any liability resulting from gross negligence, willful misconduct or bad faith in the performance of its duties.

Expenses; Sales of SUI

The Trust’s only ordinary recurring expense is expected to be the Sponsor’s Fee. From inception to February 17, 2026, the Sponsor’s Fee was 2.5%. Effective February 18, 2026, the Sponsor’s Fee was lowered to 0.35%. The Sponsor’s Fee accrues daily in U.S. dollars at an annual rate of 0.35% of the NAV Fee Basis Amount of the Trust as of 4:00 p.m., New York time, on each day; provided that for a day that is not a business day, the calculation will be based on the NAV Fee Basis Amount from the most recent business day, reduced by the accrued and unpaid Sponsor’s Fee for such most recent business day and for each day after such most recent business day and prior to the relevant calculation date. This dollar amount for each daily accrual will then be converted into SUI by reference to the same Index Price used to determine such accrual. The Sponsor’s Fee is payable in SUI to the Sponsor daily in arrears.

The Sponsor, from time to time, may temporarily waive all or a portion of the Sponsor’s Fee in its sole discretion for stated periods of time. Effective February 18, 2026, the Sponsor has determined to waive the entire Sponsor’s Fee until the earlier of (x) May 18, 2026

or (y) the first date on which the NAV of the Trust exceeds $1.0 billion (such period, the “Fee Waiver
Period”). If the Trust’s NAV exceeded $1.0 billion prior to May 18, 2026, the Sponsor’s Fee charged on assets over $1.0 billion would become 0.35%. All investors will incur the same Sponsor’s Fee, which is the weighted average for those fee rates. Following the expiration of the Fee Waiver Period on May 18, 2026, the effective Sponsor’s Fee will be 0.35%. From February 18, 2026 to the date of this Annual Report, the Trust’s assets did not exceed $1.0 billion and no Sponsor’s Fee had been incurred.

Expenses to Be Paid by the Sponsor

The Trust pays the Sponsor’s Fee to the Sponsor. As partial consideration for its receipt of the Sponsor’s Fee from the Trust, the Sponsor is obligated under the Trust Agreement to assume and pay all fees and other expenses incurred by the Trust in the ordinary course of its affairs, excluding taxes, but including: (i) the Marketing Fee; (ii) the Administrator Fee, if any; (iii) the Custodian Fee and fees for any other security vendor engaged by the Trust; (iv) the Transfer Agent Fee; (v) the Trustee fee; (vi) fees and expenses related to the listing, quotation or trading of the Shares on any Secondary Market (including customary legal, marketing and audit fees and expenses) in an amount up to $600,000 in any given fiscal year; (vii) ordinary course legal fees and expenses; (viii) audit fees; (ix) regulatory fees, including, if applicable, any fees relating to registration of the Shares under the Securities Act or the Exchange Act; (x) printing and mailing costs; (xi) the costs of maintaining the Trust’s website; and (xii) applicable license fees (each a “Sponsor-paid Expense”), provided that any expense that qualifies as an Additional Trust Expense will be deemed to be an Additional Trust Expense and not a Sponsor-paid Expense. The Sponsor, from time to time, may temporarily waive all or a portion of the Sponsor’s Fee of the Trust in its discretion for stated periods of time. Presently, the Sponsor does not intend to waive any of the Sponsor’s Fee for the Trust and, except as set forth above, there are no circumstances under which the Sponsor has determined it will definitely waive the fee. The Sponsor is under no obligation to waive any portion of its fees, and any such waiver shall create no obligation to waive any such fees during any period not covered by the waiver.

The Sponsor’s Fee will generally be paid in SUI.

After the Trust’s payment of the Sponsor’s Fee to the Sponsor, the Sponsor may elect to convert the SUI received as payment of the Sponsor’s Fee into U.S. dollars. The rate at which the Sponsor converts such SUI to U.S. dollars may differ from the rate at which the relevant Sponsor’s Fee was determined. The Trust will not be responsible for any fees and expenses incurred by the Sponsor to convert SUI received in payment of the Sponsor’s Fee into U.S. dollars.

Extraordinary and Other Expenses

In certain extraordinary circumstances, the Trust may incur certain extraordinary, non-recurring expenses that are not Sponsor-paid Expenses, including, but not limited to: taxes and governmental charges; expenses and costs of any extraordinary services performed by the Sponsor (or any other service provider) on behalf of the Trust to protect the Trust or the interests of shareholders; any indemnification of the Custodian or other agents, service providers or counterparties of the Trust; the fees and expenses related to the listing, quotation or trading of the Shares on any Secondary Market (including legal, marketing and audit fees and expenses) to the extent exceeding $600,000 in any given fiscal year; and extraordinary legal fees and expenses, including any legal fees and expenses incurred in connection with litigation, regulatory enforcement or investigation matters (collectively, “Additional Trust Expenses”). If Additional Trust Expenses are incurred, the Trust will be required to pay these Additional Trust Expenses by selling or delivering SUI. Generally, the Sponsor will cover such expenses on behalf of the Trust and the Trust will reimburse the Sponsor by delivering to the Sponsor SUI in an amount equal to such expenses. When the Trust and the Sponsor, acting on behalf of the Trust, sell or deliver, as applicable, SUI, they generally do not transact directly with counterparties other than the Authorized Participants, a Liquidity Provider or other similarly eligible financial institutions that are subject to federal and state licensing requirements and maintain practices and policies designed to comply with AML and KYC regulations.

The Sponsor or any of its affiliates may be reimbursed only for the actual cost to the Sponsor or such affiliate of any expenses that it advances on behalf of the Trust for payment of which the Trust is responsible. In addition, the Trust Agreement prohibits the Trust from paying to the Sponsor or such affiliate for indirect expenses incurred in performing services for the Trust in its capacity as the Sponsor (or an affiliate of the Sponsor) of the Trust, such as salaries and fringe benefits of officers and directors, rent or depreciation, utilities and other administrative items generally falling within the category of the Sponsor’s “overhead.”

Disposition of SUI

To cause the Trust to pay the Sponsor’s Fee, the Sponsor will instruct the Custodian to (i) withdraw from the Vault Balance the amount of SUI, determined as described above in “—Expenses; Sales of SUI,” equal to the accrued but unpaid Sponsor’s Fee and (ii) transfer such SUI to an account maintained by the Custodian for the Sponsor at such times as the Sponsor determines in its absolute discretion. In addition, if the Trust incurs any Additional Trust Expenses, the Sponsor or its delegates (i) will instruct the Custodian to withdraw from the Vault Balance SUI in such quantity as may be necessary to permit payment of such Additional Trust Expenses and (ii) may either (x) cause the Trust to convert such SUI into U.S. dollars or other fiat currencies at the Actual Exchange Rate or (y) when the Sponsor incurs such expenses on behalf of the Trust, cause the Trust (or its delegate) to deliver such SUI in-kind to the Sponsor, in each case in such quantity as may be necessary to permit payment of such Additional Trust Expenses. The Sponsor’s Fee and Additional

Trust Expenses payable by the Trust will generally be paid in SUI. Shareholders do not have the option of choosing to pay their proportionate shares of Additional Trust Expenses in lieu of having their shares of Additional Trust Expenses paid by the Trust’s delivery or disposition of SUI. Assuming that the Trust is a grantor trust for U.S. federal income tax purposes, the transfer or sale of SUI to pay the Trust’s expenses will be a taxable event for shareholders. See “Material U.S. Federal Income Tax Consequences—Tax Consequences to U.S. Holders.”

Because the amount of SUI held by the Trust will decrease as a consequence of the payment of the Sponsor’s Fee in SUI or the sale of SUI to pay Additional Trust Expenses (and the Trust will incur additional fees associated with converting SUI into U.S. dollars), the amount of SUI represented by a Share will decline at such time and the Trust’s NAV may also decrease. Accordingly, the shareholders will bear the cost of the Sponsor’s Fee and any Additional Trust Expenses. New SUI deposited into the Vault Balance in exchange for additional new Baskets issued by the Trust will not reverse this trend.

The Sponsor will also cause the sale of the Trust’s SUI if the Sponsor determines that sale is required by applicable law or regulation or in connection with the termination and liquidation of the Trust. The Sponsor will not be liable or responsible in any way for depreciation or loss incurred by reason of any sale of SUI.

The quantity of SUI to be delivered to the Sponsor or other relevant payee in payment of the Sponsor’s Fee or any Additional Trust Expenses, or sold to permit payment of Additional Trust Expenses, will vary from time to time depending on the level of the Trust’s expenses and the value of SUI held by the Trust. See “—Expenses; Sales of SUI.” Assuming that the Trust is a grantor trust for U.S. federal income tax purposes, each delivery or sale of SUI by the Trust for the payment of expenses will be a taxable event to shareholders. See “—Material U.S. Federal Income Tax Consequences—Tax Consequences to U.S. Holders.”

Discretion of the Index Provider

The Index Provider has sole discretion over the determination of the Index Price and may change the methodologies for determining the Index Price from time to time.

Description of the Trust Agreement

The following is a description of the material terms of the Trust Agreement. The Trust Agreement establishes the roles, rights and duties of the Sponsor and the Trustee.

The Sponsor

Liability of the Sponsor and Indemnification

Neither the Sponsor nor the Trust insure the Trust’s SUI. The Sponsor and its affiliates (each a “Covered Person”) will not be liable to the Trust or any shareholder for any loss suffered by the Trust which arises out of any action or inaction of such Covered Person if such Covered Person determined in good faith that such course of conduct was in the best interests of the Trust. However, the preceding liability exclusion will not protect any Covered Person against any liability resulting from its own willful misconduct, bad faith or gross negligence in the performance of its duties.

Each Covered Person will be indemnified by the Trust against any loss, judgment, liability, expense incurred or amount paid in settlement of any claim sustained by it in connection with the Covered Person’s activities for the Trust, provided that (i) the Covered Person was acting on behalf of, or performing services for, the Trust and had determined, in good faith, that such course of conduct was in the best interests of the Trust and such liability or loss was not the result of fraud, gross negligence, bad faith, willful misconduct or a material breach of the Trust Agreement on the part of such Covered Person and (ii) any such indemnification will be recoverable only from the property of the Trust. Any amounts payable to an indemnified party will be payable in advance under certain circumstances.

Fiduciary and Regulatory Duties of the Sponsor

The Sponsor is not effectively subject to the duties and restrictions imposed on “fiduciaries” under both statutory and common law. Rather, the general fiduciary duties that would apply to the Sponsor are defined and limited in scope by the Trust Agreement.

Under Delaware law, a shareholder may bring a derivative action if the shareholder is a shareholder at the time the action is brought and either (i) was a shareholder at the time of the transaction at issue or (ii) acquired the status of shareholder by operation of law or the Trust’s governing instrument from a person who was a shareholder at the time of the transaction at issue. Additionally, Section 3816(e) of the Delaware Statutory Trust Act specifically provides that “a beneficial owner’s right to bring a derivative action may be subject to such additional standards and restrictions, if any, as are set forth in the governing instrument of the statutory trust, including, without limitation, the requirement that beneficial owners owning a specified beneficial interest in the statutory trust join in the bringing of the derivative action.” In addition to the requirements of applicable law, Section 7.4 of the Trust Agreement provides that no shareholder will have the right, power or authority to bring or maintain a derivative action, suit or other proceeding on behalf of the Trust unless two or more shareholders who (i) are not “Affiliates” (as defined in the Trust Agreement and below) of one another and (ii) collectively hold at least 10.0% of the outstanding Shares join in the bringing or maintaining of such action, suit or other proceeding.

The Trust selected the 10.0% ownership threshold because the Trust believed that this was a threshold that investors would be comfortable with based on market precedent.

This provision applies to any derivative action brought in the name of the Trust other than claims brought under the federal securities laws or the rules and regulations thereunder, to which Section 7.4 does not apply. Due to this additional requirement, a shareholder attempting to bring a derivative action in the name of the Trust will be required to locate other shareholders with which it is not affiliated and that have sufficient Shares to meet the 10.0% threshold based on the number of Shares outstanding on the date the claim is brought and thereafter throughout the duration of the action, suit or proceeding.

“Affiliate” is defined in the Trust Agreement to mean any natural person, partnership, limited liability company, statutory trust, corporation, association or other legal entity (each, a “Person”) directly or indirectly owning, controlling or holding with power to vote 10% or more of the outstanding voting securities of such Person, (ii) any Person 10% or more of whose outstanding voting securities are directly or indirectly owned, controlled or held with power to vote by such Person, (iii) any Person, directly or indirectly, controlling, controlled by or under common control of such Person, (iv) any employee, officer, director, member, manager or partner of such Person, or (v) if such Person is an employee, officer, director, member, manager or partner, any Person for which such Person acts in any such capacity.

Any shareholders seeking to bring a derivative action may determine whether the 10.0% ownership threshold required to bring a derivative action has been met by dividing the number of Shares owned by such shareholders by the total number of Shares outstanding. The Trust offers Shares on a periodic basis at such times and for such periods as the Sponsor determines in its sole discretion. As a result, in order to maintain the 10.0% ownership threshold required to maintain a derivative action, shareholders may need to increase their holdings or locate additional shareholders during the pendency of a claim. The Trust posts the number of Shares outstanding as of the end of each month on its website and as of the end of each quarter in its annual and quarterly filings with the SEC. The Trust additionally reports sales of unregistered securities on Form 8-K pursuant to Item 3.02 thereof. Shareholders may monitor the number of Shares outstanding at any time for purposes of calculating their ownership threshold by reviewing the Trust’s website and SEC filings and by requesting the number of Shares outstanding on any date from the Sponsor at any time pursuant to Sections 7.2 and 8.1 of the Trust Agreement. Shareholders have the opportunity at any time to increase their holdings or locate other shareholders to maintain the 10.0% threshold throughout the duration of a derivative claim. Shareholders may do so by requesting from the Sponsor the list of the names and last known address of all shareholders pursuant to Sections 7.2 and 8.1 of the Trust Agreement and Section 3819(a) of the DSTA. Because the Trust is a grantor trust, it may only issue one class of securities, the Shares.

The Sponsor is not aware of any reason to believe that Section 7.4 of the Trust Agreement is not enforceable under state or federal law. The Court of Chancery of Delaware has stated that “[t]he DSTA is enabling in nature and, as such, permits a trust through its declarations of trust to delineate additional standards and requirements with which a stockholder-plaintiff must comply to proceed derivatively in the name of the trust.” Hartsel v. Vanguard Group, Inc., Del. Ch. June 15, 2011. However, there is limited case law addressing the enforceability of provisions like Section 7.4 under state and federal law and it is possible that this provision would not be enforced by a court in another jurisdiction or under other circumstances.

Beneficial owners may have the right, subject to certain legal requirements, to bring class actions in federal court to enforce their rights under the federal securities laws and the rules and regulations promulgated thereunder by the SEC. Beneficial owners who have suffered losses in connection with the purchase or sale of their beneficial interests may be able to recover such losses from the Sponsor where the losses result from a violation by the Sponsor of the anti-fraud provisions of the federal securities laws.

Actions Taken to Protect the Trust

The Sponsor may prosecute, defend, settle or compromise actions or claims at law or in equity that it considers necessary or proper to protect the Trust or the interests of the shareholders. The expenses incurred by the Sponsor in connection therewith (including the fees and disbursements of legal counsel) will be expenses of the Trust and are deemed to be Additional Trust Expenses. The Sponsor will be entitled to be reimbursed for the Additional Trust Expenses it pays on behalf of the Trust.

Successor Sponsors

If the Sponsor is adjudged bankrupt or insolvent, the Trust may dissolve and a Liquidating Trustee may be appointed to terminate and liquidate the Trust and distribute its remaining assets. The Trustee will have no obligation to appoint a successor sponsor or to assume the duties of the Sponsor, and will have no liability to any person because the Trust is or is not terminated. However, if a certificate of dissolution or revocation of the Sponsor’s charter is filed (and ninety (90) days have passed after the date of notice to the Sponsor of revocation without a reinstatement of the Sponsor’s charter) or the withdrawal, removal, adjudication or admission of bankruptcy or insolvency of the Sponsor has occurred, shareholders holding at least a majority (over 50%) of the Shares may agree in writing to continue the affairs of the Trust and to select, effective as of the date of such event, one or more successor sponsors within ninety (90) days of any such event.

The Trustee

The Trustee is a fiduciary under the Trust Agreement and must satisfy the requirements of Section 3807 of the Delaware Statutory Trust Act. However, the fiduciary duties, responsibilities and liabilities of the Trustee are limited by, and are only those specifically set forth in, the Trust Agreement.

Limitation on Trustee’s Liability

Under the Trust Agreement, the Sponsor has exclusive control of the management of all aspects of the activities of the Trust and the Trustee has only nominal duties and liabilities to the Trust. The Trustee is appointed to serve as the trustee for the sole purpose of satisfying Section 3807(a) of the DSTA which requires that the Trust have at least one trustee with a principal place of business in the State of Delaware. The duties of the Trustee are limited to (i) accepting legal process served on the Trust in the State of Delaware and (ii) the execution of any certificates required to be filed with the Delaware Secretary of State which the Trustee is required to execute under the DSTA.

To the extent the Trustee has duties (including fiduciary duties) and liabilities to the Trust or the shareholders under the DSTA, such duties and liabilities will be replaced by the duties and liabilities of the Trustee expressly set forth in the Trust Agreement. The Trustee will have no obligation to supervise, nor will it be liable for, the acts or omissions of the Sponsor, Transfer Agent, Custodian or any other person. Neither the Trustee, either in its capacity as trustee or in its individual capacity, nor any director, officer or controlling person of the Trustee is, or has any liability as, the issuer, director, officer or controlling person of the issuer of Shares. The Trustee’s liability is limited solely to the express obligations of the Trustee as set forth in the Trust Agreement.

Under the Trust Agreement, the Sponsor has the exclusive management, authority and control of all aspects of the activities of the Trust. The Trustee has no duty or liability to supervise or monitor the performance of the Sponsor, nor does the Trustee have any liability for the acts or omissions of the Sponsor. The existence of a trustee should not be taken as an indication of any additional level of management or supervision over the Trust. The Trust Agreement provides that the management authority with respect to the Trust is vested directly in the Sponsor and that the Trustee is not responsible or liable for the genuineness, enforceability, collectability, value, sufficiency, location or existence of any of the SUI or other assets of the Trust.

Possible Repayment of Distributions Received by Shareholders; Indemnification by Shareholders

The Shares are limited liability investments. Investors may not lose more than the amount that they invest plus any profits recognized on their investment. Although it is unlikely, the Sponsor may, from time to time, make distributions to the shareholders. However, shareholders could be required, as a matter of bankruptcy law, to return to the estate of the Trust any distribution they received at a time when the Trust was in fact insolvent or in violation of its Trust Agreement. In addition, the Trust Agreement provides that shareholders will indemnify the Trust for any harm suffered by it as a result of shareholders’ actions unrelated to the activities of the Trust.

The foregoing repayment of distributions and indemnity provisions (other than the provision for shareholders indemnifying the Trust for taxes imposed upon it by a state, local or foreign taxing authority, which is included only as a formality due to the fact that many states do not have statutory trust statutes therefore the tax status of the Trust in such states might, theoretically, be challenged) are commonplace in statutory trusts and limited partnerships.

Indemnification of the Trustee

The Trustee and any of the officers, directors, employees and agents of the Trustee will be indemnified by the Trust as primary obligor and the Sponsor as secondary obligor and held harmless against any loss, damage, liability, claim, action, suit, cost, expense, disbursement (including the reasonable fees and expenses of counsel), tax or penalty of any kind and nature whatsoever, arising out of, imposed upon or asserted at any time against such indemnified person in connection with the performance of its obligations under the Trust Agreement, the creation, operation or termination of the Trust or the transactions contemplated therein; provided, however, that neither the Trust nor the Sponsor will be required to indemnify any such indemnified person for any such expenses which are a result of the willful misconduct, bad faith or gross negligence of such indemnified person. If the Trust has insufficient assets or improperly refuses to pay such an indemnified person within 60 days of a request for payment owed under the Trust Agreement, the Sponsor will, as secondary obligor, compensate or reimburse the Trustee or indemnify, defend and hold harmless such an indemnified person as if it were the primary obligor under the Trust Agreement. Any amount payable to such an indemnified person under the Trust Agreement may be payable in advance under certain circumstances and will be secured by a lien on the Trust property. The obligations of the Sponsor and the Trust to indemnify such indemnified persons under the Trust Agreement will survive the termination of the Trust Agreement.

Holding of Trust Property

The Trust will hold and record the ownership of the Trust’s assets in a manner such that it will be owned for the benefit of the shareholders for the purposes of, and subject to and limited by the terms and conditions set forth in, the Trust Agreement. The Trust will

not create, incur or assume any indebtedness or borrow money from or loan money to any person. The Trustee may not commingle its assets with those of any other person.

The Trustee may employ agents, attorneys, accountants, auditors and nominees and will not be answerable for the conduct or misconduct of any such custodians, agents, attorneys or nominees if such custodians, agents, attorneys and nominees have been selected with reasonable care.

Resignation, Discharge or Removal of Trustee; Successor Trustees

The Trustee may resign as Trustee by written notice of its election so to do, delivered to the Sponsor with at least 180 days’ notice. The Sponsor may remove the Trustee in its discretion. If the Trustee resigns or is removed, the Sponsor, acting on behalf of the shareholders, will appoint a successor trustee. The successor Trustee will become fully vested with all of the rights, powers, duties and obligations of the outgoing Trustee.

If the Trustee resigns and no successor trustee is appointed within 180 days after the Trustee notifies the Sponsor of its resignation, the Trustee will terminate and liquidate the Trust and distribute its remaining assets.

Amendments to the Trust Agreement

In general, the Sponsor may amend the Trust Agreement without the consent of any shareholder. In particular, the Sponsor may, without the approval of the shareholders, amend the Trust Agreement if the Trust is advised at any time by the Trust’s accountants or legal counsel that the amendments are necessary to permit the Trust to take the position that it is a grantor trust for U.S. federal income tax purposes. The Sponsor is also permitted to make certain restatements, amendments or supplements to the Trust Agreement that would materially adversely affect the interests of the shareholders as determined by the Sponsor in its sole discretion with a 20-day notice to shareholders. Additionally, the Sponsor is permitted to make certain restatements, amendments or supplements to the Trust Agreement that could adversely affect the status of the Trust as a grantor trust for U.S. federal income tax purposes, but only if certain conditions set forth in the amendments relating to the qualification of the Trust as a grantor trust for U.S. federal income tax purposes are satisfied. Furthermore, subject to certain limitations, the Sponsor may make any other amendments to the Trust Agreement which do not materially adversely affect the interests of the shareholders in its sole discretion without shareholder consent.

Termination of the Trust

Upon dissolution of the Trust and surrender of Shares by the shareholders, shareholders will receive a distribution in U.S. dollars or in SUI at the sole discretion of the Sponsor, after the Sponsor has sold the Trust’s SUI, if applicable, and has paid or made provision for the Trust’s claims and obligations.

If the Trust is forced to liquidate, the Trust will be liquidated under the Sponsor’s direction. The Sponsor, on behalf of the Trust, will engage directly with Digital Asset Markets to liquidate the Trust’s SUI as promptly as possible while obtaining the best fair value possible. The proceeds therefrom will be applied and distributed in the following order of priority: (a) to the expenses of liquidation and termination and to creditors, including shareholders who are creditors, to the extent otherwise permitted by law, in satisfaction of liabilities of the Trust other than liabilities for distributions to shareholders and (b) to the holders of Shares pro rata in accordance with the respective percentages of Shares that they hold. It is expected that the Sponsor would be subject to the same regulatory requirements as the Trust, and therefore, the markets available to the Sponsor will be the same markets available to the Trust.

Governing Law

The Trust Agreement and the rights of the Sponsor, Trustee and shareholders under the Trust Agreement are governed by the laws of the State of Delaware.

Description of the Prime Broker Agreement

The Prime Broker Agreement establishes the rights and responsibilities of the Custodian, the Prime Broker, the Sponsor and the Trust with respect to the Trust’s SUI which is held in accounts maintained and operated by the Custodian, as a fiduciary with respect to the Trust’s assets, and the Prime Broker (together with the Custodian, the “Custodial Entities”) on behalf of the Trust. For a general description of the Custodian’s obligations, see “—Service Providers of the Trust—The Custodian and Prime Broker.”

Account; Location of SUI

All of the Trust’s SUI, other than that which is credited to a settlement balance maintained with the Prime Broker (the “Settlement Balance”), is held in custody accounts maintained on the books of the Custodian, as to which the Custodian controls the private keys which allow for the transfer of ownership or control of the Trust’s SUI on the Trust’s behalf (the “Vault Balance”). The Prime Broker

Agreement provides that the Trust’s Vault Balance will be held by the Custodian in segregated wallets or accounts. The Custodian will keep all of the private keys associated with the Trust’s SUI held in the Vault Balance in an offline manner. The term “cold storage” refers to a safeguarding method where the storage of private keys may involve keeping such keys’ materials on a non-networked computer or electronic device or storing the private keys on a storage device. Cold storage is a safeguarding method with multiple layers of protections and protocols, by which the private keys corresponding to the Trust’s SUI are generated and stored in an offline manner. The term “hot storage” refers to the safeguarding method by which the private keys are held online, where they are more accessible, leading to more efficient transfers, though they are potentially more vulnerable to theft, loss or damage.

Additionally, at the Sponsor’s discretion, a portion of the Trust’s SUI holdings may be credited to the Settlement Balance, which will be reflected in a ledger maintained on the books of the Prime Broker. The Prime Broker Agreement provides that any SUI credited to the Trust’s Settlement Balance will be held (i) in omnibus cold storage wallets; (ii) in omnibus hot storage wallets; or (iii) in omnibus accounts with one of the third-party venues to which Coinbase has established connections (each, a “Coinbase Connected Venue”). The Settlement Balance shall be separate from the Vault Balance and any other account(s) the Trust or the Sponsor maintain with the Custodian. From time to time, the Prime Broker may temporarily keep a portion of the private keys associated with the SUI credited to the Trust’s Settlement Balance in hot storage for purposes of facilitating the receipt and distribution of SUI in connection with the creation and redemption of Baskets.

Private key shards associated with the Trust’s SUI are distributed geographically by the Custodial Entities in secure vaults around the world, including in the United States. The locations of the secure vaults may change and are kept confidential by the Custodian for security purposes.

The Prime Broker Agreement states that the Custodian serves as a fiduciary and custodian on the Trust’s behalf with respect to the Trust’s SUI held in the Vault Balance and the SUI in the Vault Balance are considered fiduciary assets that remain the Trust’s property at all times and are not treated as general assets of the Custodian. Under the Prime Broker Agreement, the Custodian represents and warrants that it has no right, interest, or title in the SUI in the Trust’s Vault Balance, and agrees that it will not, directly or indirectly, lend, pledge, hypothecate or rehypothecate such digital assets. The Custodian does not reflect such digital assets as assets on the balance sheet of the Custodian, but does reflect the obligation to safeguard such digital assets with a corresponding asset measured at fair value for such obligation. With respect to the Trust’s SUI credited to the Settlement Balance, the Prime Broker maintains an internal ledger that specifies the SUI credited to the Trust’s Settlement Balance. The Prime Broker Agreement states that the Prime Broker treats such SUI as custodial assets held for the benefit of the Trust, and shall not be considered the property of the Prime Broker. Additionally, under the Prime Broker Agreement, the Prime Broker represents and warrants that it will not, directly or indirectly, sell, transfer, loan, rehypothecate or otherwise alienate the Trust’s SUI credited to the Settlement Balance.

The Prime Broker Agreement also contains an agreement by the parties to treat the digital assets credited to the Trust’s Vault Balance and Settlement Balance as “financial assets” under Article 8 of the New York Uniform Commercial Code (“Article 8”) and to treat the Vault Balance and Settlement Balance as “securities accounts” with respect to which the Trust is the “entitlement holder” within the meaning of Article 8. The Custodial Entities’ ultimate parent, Coinbase Global, Inc. (“Coinbase Global”), has stated in its public securities filings that in light of the inclusion in its custody agreements of provisions relating to Article 8 it believes that a court would not treat custodied digital assets as part of its general estate, although due to the novelty of digital assets courts have not yet considered this type of treatment for custodied digital assets. See “Item 1A. Risk Factors—Risk Factors Related to the Trust and the Shares—The Trust relies on third-party service providers to perform certain functions essential to the affairs of the Trust and the replacement of such service providers could pose challenges to the safekeeping of the Trust’s SUI and to the operations of the Trust.”

Safekeeping of SUI

The Custodian will use commercially reasonable efforts to keep in safe custody on behalf of the Trust all SUI received by the Custodian. All SUI credited to the Vault Balance will (i) be held in the Vault Balance at all times, and the Vault Balance will be controlled by the Custodian; (ii) be labeled or otherwise appropriately identified as being held for the Trust; (iii) be held on a non-fungible basis; (iv) not be commingled with other digital assets held by the Custodian, whether held for the Custodian’s own account or the account of other clients other than the Trust; and (v) not without the prior written consent of the Trust be deposited or held with any third-party depositary, custodian, clearance system or wallet. Additionally, the Custodian will use commercially reasonable efforts to keep the private key or keys for the Vault Balance secure, and will not disclose such keys to the Trust, the Sponsor or to any other individual or entity except to the extent that any keys are disclosed consistent with a standard of commercially reasonable efforts and as part of a multiple signature solution that would not result in the Trust or the Sponsor “storing, holding, or maintaining custody or control of” the SUI “on behalf of others” within the meaning of the New York BitLicense Rule (23 NYCRR Part 200) as in effect as of June 24, 2015 such that it would require the Trust or the Sponsor to become licensed under such law.

SUI credited to the Trust’s Settlement Balance may be held in omnibus wallets maintained by the Prime Broker and/or at Coinbase Connected Venues. While the SUI credited to the Trust’s Settlement Balance could be commingled with other assets, the SUI in the Trust’s Settlement Balance will represent entitlement to a pro-rata share of the SUI held in such omnibus wallets and/or at Coinbase Connected Venues. In all circumstances the Prime Broker will keep an internal ledger that specifies the assets credited to the Settlement Balance such that the Trust, its auditors and regulators can identify the Trust’s pro-rata share of the SUI held in omnibus wallets and/or

at Coinbase Connected Venues. Neither the Trust nor the Sponsor have a contractual relationship with the Coinbase Connected Venues utilized by the Custodial Entities.

Insurance

Pursuant to the terms of the Prime Broker Agreement, the Custodian is required to maintain insurance in such types and amounts as are commercially reasonable for the custodial services it provides. The Custodian has advised the Sponsor that it has insurance coverage pursuant to policies held by Coinbase Global, which procures fidelity (or crime) insurance coverage at commercially reasonable amounts for the custodial services provided. This insurance coverage is limited to losses of the digital assets the Custodian custodies on behalf of its clients, including the Trust’s SUI, resulting from theft, including internal theft by employees of Coinbase and its subsidiaries and theft or fraud by a director of Coinbase if the director is acting in the capacity of an employee of Coinbase or its subsidiaries. Although the Prime Broker is not required to maintain insurance under the terms of the Prime Broker Agreement, the Custodial Entities have also advised the Sponsor that they maintain insurance coverage pursuant to such policies held by Coinbase Global.

Moreover, while the Custodian maintains certain capital reserve requirements depending on the assets under custody and to the extent required by applicable law, and such capital reserves may provide additional means to cover client asset losses, the Sponsor does not know the amount of such capital reserves, and neither the Trust nor the Sponsor have access to such information. The Trust cannot be assured that the Custodian will maintain capital reserves sufficient to cover losses with respect to the Trust’s digital assets. Furthermore, Coinbase has represented in securities filings that the total value of crypto assets in its possession and control is significantly greater than the total value of insurance coverage that would compensate Coinbase in the event of theft or other loss of funds.

Deposits, Withdrawals and Storage

The Custodian and the Prime Broker provide for: (i) holding of the Trust’s SUI in the Vault Balance and the Settlement Balance; (ii) transfer of the Trust’s SUI between the relevant Vault Balance and the Settlement Balance; (iii) the deposit of SUI from a public blockchain address into the respective account or accounts in which the Vault Balance or the Settlement Balance are maintained; and (iv) the withdrawal of SUI from the Vault Balance to a public blockchain address the Trust controls (each such transaction is a “Custody Transaction”) (collectively, the “Custodial and Prime Broker Services”).

The Custodian reserves the right to refuse to process or to cancel any pending Custody Transaction as required by law or in response to a subpoena, court order, or other binding government order or to enforce transaction, threshold, and condition limits, in each case as communicated to the Trust as soon as reasonably practicable where the Custodian is permitted to do so, or if the Custodian reasonably believes that the Custody Transaction may violate or facilitate the violation of an applicable law, regulation or applicable rule of a governmental authority or self-regulatory organization. The Custodial Entities may suspend, restrict, or terminate the Trust’s and the Sponsor’s access to the Custodial and Prime Broker Services, and/or suspend, restrict, or close the accounts associated with the Trust’s Vault Balance and Settlement Balance (the “Accounts”) if the Trust or Sponsor has taken certain actions, including any prohibited use or prohibited business as set forth in the Prime Broker Agreement, or if either or both of the Custodial Entities are required to do so by a subpoena, court order, or other binding government order.

From the time the Custodian has verified the authorization of a complete set of instructions to withdraw SUI from the Vault Balance, the Custodian will have a limited amount of time to process and complete such withdrawal. The Custodian will ensure that initiated deposits are processed in a timely manner but the Custodian makes no representations or warranties regarding the amount of time needed to complete processing which is dependent upon many factors outside of the Custodian’s control.

Transactions relating to SUI held in the Settlement Balance occur on the Blockchain.

The Custodial Entities make no other representations or warranties with respect to the availability and/or accessibility of SUI or the availability and/or accessibility of the Vault Balance, the Settlement Balance or the Custodial and Prime Broker Services.

Security of the Accounts

The Custodial Entities securely store all digital asset private keys held by the Custodian on secure servers or offline, in cold storage. Under the Prime Broker Agreement, the Custodian must use commercially reasonable efforts to keep the private key or keys to the Vault Balance secure, and may not disclose such private keys to the Sponsor, Trust or any other individual or entity.

The Custodial Entities have implemented and will maintain reasonable information security programs that include policies and procedures that are reasonably designed to safeguard the Custodial Entities’ electronic systems and the Trust’s and the Sponsor’s confidential information from, among other things, unauthorized access or misuse. In the event of a Data Security Event (as defined in the Prime Broker Agreement), the Custodial Entities will promptly (subject to any legal or regulatory requirements) notify the Trust and the Sponsor.

Record Keeping; Inspection and Auditing

The Custodian will keep timely and accurate records as to the deposit, disbursement, investment and reinvestment of the SUI in the Vault Balance, and such records must be retained by the Custodian for no less than seven years. The Prime Broker Agreement also provides that each Custodial Entity will permit, to the extent it may legally do so, the Trust’s third-party representatives, upon thirty days’ notice, to inspect, take extracts from and audit the records that it maintains, take such steps as necessary to verify that satisfactory internal control systems and procedures are in place, as the Trust may reasonably request. The Prime Broker is obligated to notify the Trust of any audit report prepared by its internal or independent auditors if such report reveals any material deficiencies or makes any material objections.

The Trust and the Sponsor obtain and perform a comprehensive review of the Services Organization Controls (“SOC”) 1 report and SOC 2 each year. For additional information, see “—Description of Trust Documents—Description of the Prime Broker Agreement—Annual Certificate and Report.” In addition to the review of SOC 1 and SOC 2 reports, the Trust, the Sponsor and/or their respective auditors may inspect or audit the Custodian’s records in a variety of manners if considered necessary. Such processes, may include validating the existing balances as reflected on the Custodian’s user interface to nodes of the underlying blockchain and confirming that such digital assets are associated with its public keys to validate the existence and exclusive ownership of the digital assets. To validate software functionality of the private keys, the Trust may transfer a portion of its digital assets from one public key to another public key of the Trust.

The Trust, the Sponsor and their independent auditors may evaluate the Custodian’s protection of private keys and other customer information, including review of supporting documentation related to the processes surrounding key lifecycle management, the key generation process (hardware, software, and algorithms associated with generation) the infrastructure used to generate and store private keys, how private keys are stored (for example, cold wallets), the segregation of duties in the authorization of digital asset transactions, and the number of users required to process a transaction and the monitoring of addresses for any unauthorized activity. For additional information, see “—Custody of the Trust’s SUI.”

Once each calendar year, the Trust and the Sponsor are entitled to request that the Custodial Entities provide a copy of the SOC 1 report and SOC 2 report once per calendar year. Such reports are required to be dated within one year prior to such request. The Custodial Entities reserve the right to combine the SOC 1 and SOC 2 reports into a comprehensive report. In the event that the Custodial Entities do not deliver a SOC 1 Report or SOC 2 Report, as applicable, the Sponsor and the Trust will be entitled to terminate the Prime Broker Agreement. In addition to the review of SOC 1 and SOC 2 reports, the Trust may also request letters of representation on a quarterly basis between SOC reports regarding any known changes or conclusions to the SOC 1 and SOC 2 report.

Standard of Care; Limitations of Liability

The Custodian will use commercially reasonable efforts to keep in safe custody on behalf of the Trust all SUI received by the Custodian. The Custodial Entities are liable to the Sponsor and the Trust for the loss of any SUI to the extent such loss resulted from the negligence, fraud or willful misconduct of the Custodial Entities. To the extent any loss is caused by a Custodial Entity’s negligence, fraud or willful misconduct, the Custodial Entities are required to return to the Trust a quantity of SUI equal to the quantity of any such lost SUI.

The Custodial Entities’ or Trust’s total liability under the Prime Broker Agreement will not exceed the greater of: (i) the value of the SUI or cash involved in the event, including but not limited to transaction(s) or deliveries(s), giving rise to such liability at the time of the event giving rise to such liability; (ii) the aggregate amount of fees paid by the Trust to the Custodial Entities in respect of the Custodial and Prime Broker Services in the 12-month period prior to the event giving rise to such liability; or (iii) five million U.S. dollars. The Custodian’s total liability under the Prime Broker Agreement will not exceed the greater of: (i) the aggregate amount of fees paid by the Trust to the Custodian in respect of the custodial services in the 12-month period prior to the event giving rise to such liability; or (ii) the value of the SUI on deposit in the Vault Balance at the time of the events giving rise to the liability occurred, the value of which will be determined in accordance with the Prime Broker Agreement. In addition, the Custodian’s maximum liability in respect of each cold storage address that holds SUI shall be limited to $100 million (the “Cold Storage Threshold”). The Sponsor monitors the value of SUI deposited in cold storage addresses for whether the Cold Storage Threshold has been met by determining the U.S. dollar value of SUI deposited in each cold storage address on business days. Although the Cold Storage Threshold has to date not been met for a given cold storage address, to the extent it is met the Trust would not have a claim against the Custodian with respect to the digital assets held in such address to the extent the value exceeds the Cold Storage Threshold.

The Custodial Entities and the Trust are not liable to each other for any special, incidental, indirect, punitive, or consequential damages, whether or not the other party had been advised of such losses or knew or should have known of the possibility of such damages. In addition, the Custodial Entities are not liable to the Trust for circumstances resulting from certain force majeure events.

Indemnity

The Trust and the Custodial Entities have agreed to indemnify one another from and against certain claims or losses, subject to customary exceptions and limitations.

Fees and Expenses

The Sponsor will pay an annualized fee to the Coinbase Entities, covering the Trust’s use of the Custodial and Prime Broker Services, that is accrued on a monthly basis as a percentage of the Trust’s monthly assets under custody. The Sponsor will also pay a monthly fee to the Prime Broker, covering withdrawals and deposits to or from the Settlement Balance in connection with the creation and redemption of Shares.

Term; Termination and Suspension

The Prime Broker Agreement will remain in effect until either party terminates the Prime Broker Agreement; provided, however, that the Coinbase Entities shall not restrict, suspend, or modify any Prime Broker Services following termination of the Prime Broker Agreement by a Custodial Entity without Cause (as defined in the Prime Broker Agreement) or by the Trust until the end of the applicable notice period and neither party’s termination of the Prime Broker Agreement will be effective until the Trust and/or the Custodial Entities, as the case may be, have fully satisfied their obligations thereunder.

The Trust may terminate the Prime Broker Agreement in whole or in part upon thirty days’ prior written notice to the applicable Custodial Entity; and (ii) for Custodian Cause (as defined in the Prime Broker Agreement) at any time by written notice to the Prime Broker, effective immediately, or on such later date as may be specified in such notice. The Trust will also be entitled to terminate the Prime Broker Agreement in the event that the Custodial Entities do not deliver a SOC 1 Report or SOC 2 Report, as applicable. See “—Record Keeping; Inspection and Auditing.”

The Custodial Entities may terminate the Prime Broker Agreement (i) upon one hundred eighty days’ prior written notice to the Trust; and (ii) for Cause at any time by written notice to the Trust, effective immediately, or on such later date as may be specified in the notice.

In the event that either the Trust or the Custodial Entities terminate the Prime Broker Agreement without Cause, the Custodial Entities shall use reasonable efforts to assist the Trust with transferring any digital assets, fiat currency or funds associated with the Trust’s Accounts to another custodial services provider within ninety days of receipt of the applicable termination notice.

Governing Law

The Prime Broker Agreement is governed by New York law.

MATERIAL U.S. Federal Income Tax Consequences

The following discussion addresses the material U.S. federal income tax consequences of the ownership of Shares. This discussion does not describe all of the tax consequences that may be relevant to a beneficial owner of Shares in light of the beneficial owner’s particular circumstances, including tax consequences applicable to beneficial owners subject to special rules, such as:

•

financial institutions;

•

dealers in securities or commodities;

•

traders in securities or commodities that have elected to apply a mark-to-market method of tax accounting in respect thereof;

•

persons holding Shares as part of a hedge, “straddle,” integrated transaction or similar transaction;

•

Authorized Participants (as defined below);

•

U.S. Holders (as defined below) whose functional currency is not the U.S. dollar;

•

entities or arrangements classified as partnerships for U.S. federal income tax purposes;

•

real estate investment trusts;

•

regulated investment companies; and

•

tax-exempt entities, including individual retirement accounts.

This discussion applies only to Shares that are held as capital assets and does not address alternative minimum tax consequences or consequences of the Medicare contribution tax on net investment income.

If an entity or arrangement that is classified as a partnership for U.S. federal income tax purposes holds Shares, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partnerships holding Shares and partners in those partnerships are urged to consult their tax advisers about the particular U.S. federal income tax consequences of owning Shares.

This discussion is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations (“Treasury Regulations”) as of the date hereof, changes to any of which subsequent to the date hereof may affect the tax consequences described herein. For the avoidance of doubt, this summary does not discuss any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction. Shareholders are urged to consult their tax advisers about the application of the U.S. federal income tax laws to their particular situations, as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

Tax Treatment of the Trust

The Sponsor intends to take the position that the Trust is properly treated as a grantor trust for U.S. federal income tax purposes. Assuming that the Trust is a grantor trust, the Trust will not be subject to U.S. federal income tax. Rather, if the Trust is a grantor trust, each beneficial owner of Shares will be treated as directly owning its pro rata share of the Trust’s assets and a pro rata portion of the Trust’s income, gains, losses and deductions will “flow through” to each beneficial owner of Shares.

The Staking Condition has been satisfied as to the particular form of Staking described herein, and the Sponsor intends to continue to take the position that the Trust is properly treated as a grantor trust for U.S. federal income tax purposes and that any Staking activity undertaken by the Trust in compliance with the opinion, ruling or other guidance relied upon to satisfy the Staking Condition will not prevent the Trust from continuing to qualify as a grantor trust for such purposes. The Internal Revenue Service (“IRS”) recently issued a revenue procedure providing a staking safe harbor for certain grantor trust vehicles whose beneficial interests are listed and traded on a national securities exchange (the “2025 Revenue Procedure”). However, certain aspects of the 2025 Revenue Procedure are unclear, and therefore the Trust may not currently satisfy all conditions of the safe harbor. Accordingly, due to the uncertainty regarding the ability of a grantor trust to engage in Staking activities, there can be no assurance that the IRS or any court would agree with the Sponsor’s position (or with any opinion of counsel delivered to the Sponsor in support thereof). Therefore, the Trust might cease to qualify as a grantor trust for U.S. federal income tax purposes.

Furthermore, the Sponsor has committed to cause the Trust to irrevocably abandon any Incidental Rights and IR Virtual Currency to which the Trust may become entitled in the future. In furtherance of that commitment, the Sponsor has, on behalf of the Trust, notified the Prime Broker, the Custodian, and Coinbase Credit via the Pre-Creation/Redemption Abandonment Notices (as defined herein) that the Trust is irrevocably abandoning, effective immediately prior to each Creation Time or Redemption Time, all Incidental Rights or IR Virtual Currency to which it would otherwise be entitled as of such time and with respect to which it has not taken any Affirmative

Action at or prior to such time. There can be no complete assurance that these abandonments will be treated as effective for U.S. federal income tax purposes. If the Trust were treated as owning any asset other than SUI as of any date on which it creates or redeems Shares, it might cease to qualify as a grantor trust for U.S. federal income tax purposes.

In addition, at this time the Trust is permitted to create or redeem Shares pursuant to In-Kind Orders and Cash Orders. In general, investment vehicles intended to be treated as grantor trusts for U.S. federal income tax purposes historically have created additional trust interests only in kind, and there is no authority directly addressing whether a grantor trust may create or redeem trust interests under procedures similar to those that govern Cash Orders. Accordingly, there can be no complete assurance that the creation or redemption of Shares under the procedures governing Cash Orders will not cause the Trust to fail to qualify as a grantor trust for U.S. federal income tax purposes.

Moreover, because of the evolving nature of digital assets, it is not possible to predict potential future developments that may arise with respect to digital assets, including forks, airdrops and other similar occurrences. Assuming that the Trust is currently a grantor trust for U.S. federal income tax purposes, certain future developments could render it impossible, or impracticable, for the Trust to continue to be treated as a grantor trust for such purposes.

If the Trust is not properly classified as a grantor trust, the Trust might be classified as a partnership for U.S. federal income tax purposes. However, due to the uncertain treatment of digital assets for U.S. federal income tax purposes, there can be no assurance in this regard. If the Trust were classified as a partnership for U.S. federal income tax purposes, the tax consequences of owning Shares generally would not be materially different from the tax consequences described herein, although there might be certain differences, including with respect to timing of the recognition of taxable income or loss. In addition, tax information reports provided to beneficial owners of Shares would be made in a different form. Moreover, it is possible, in that case, that a portion of the Trust’s income would be considered to be “effectively connected” with the conduct of a trade or business in the United States and, accordingly, a non-U.S. person owning Shares could be subject to U.S. federal income tax on a net income basis with respect to that “effectively connected” income and be required to file a U.S. tax return. If none of the Trust’s Staking income were considered to be “effectively connected” income, a non-U.S. person owning Shares might be subject to withholding on its pro rata portion of U.S.-source “fixed or determinable annual or periodical” (“FDAP”) income as described below. Tax-exempt shareholders may also recognize “unrelated business taxable income” (“UBTI”) from the Trust’s Staking activities if the Trust is not treated as a corporation for U.S. federal income tax purposes.

If the Trust were not classified as either a grantor trust or a partnership for U.S. federal income tax purposes, it would be classified as a corporation for such purposes. In that event, the Trust would be subject to entity-level U.S. federal income tax (currently at the rate of 21%) on its net taxable income and certain distributions made by the Trust to shareholders would be treated as taxable dividends to the extent of the Trust’s current and accumulated earnings and profits. Any such dividend distributed to a beneficial owner of Shares that is a non-U.S. person for U.S. federal income tax purposes would be subject to U.S. federal withholding tax at a rate of 30% (or such lower rate as provided in an applicable tax treaty).

The remainder of this discussion is based on the assumption that the Trust will be treated as a grantor trust for U.S. federal income tax purposes.

Uncertainty Regarding the U.S. Federal Income Tax Treatment of Digital Assets

Each beneficial owner of Shares will be treated for U.S. federal income tax purposes as the owner of an undivided interest in the SUI (and any Incidental Rights and/or IR Virtual Currency) held in the Trust. Due to the new and evolving nature of digital assets and the absence of comprehensive guidance with respect to digital assets, many significant aspects of the U.S. federal income tax treatment of digital assets are uncertain.

In 2014, the IRS released a notice (the “Notice”) discussing certain aspects of the treatment of “convertible virtual currency” (that is, digital assets that have an equivalent value in fiat currency or that act as substitutes for fiat currency) for U.S. federal income tax purposes. In the Notice, the IRS stated that, for U.S. federal income tax purposes, such digital assets (i) are “property,” (ii) are not “currency” for purposes of the provisions of the Code relating to foreign currency gain or loss and (iii) may be held as a capital asset. In 2019, the IRS released a revenue ruling and a set of “Frequently Asked Questions” that has been updated from time to time since (the “Ruling & FAQs”). The Ruling & FAQs provide some additional guidance, including guidance to the effect that, under certain circumstances, hard forks of digital assets are taxable events giving rise to ordinary income and guidance with respect to the determination of the tax basis of digital assets. Moreover, in 2023, the IRS released a revenue ruling that provided guidance on digital asset staking, including guidance to the effect that staking rewards will, under certain circumstances, be treated as giving rise to taxable income (the “2023 Staking Guidance”). Further, the IRS recently issued the 2025 Revenue Procedure, which provides a staking safe harbor for certain grantor trust vehicles. However, the Notice, the Ruling & FAQs, the 2023 Staking Guidance and the 2025 Revenue Procedure do not address other significant aspects of the U.S. federal income tax treatment of digital assets. For example, for a non-U.S. Holder, there currently is no guidance directly addressing whether or in what circumstances engaging in certain activities to generate yield on digital assets, including Staking, could give rise to income that is effectively connected with a trade or business in the United

States. Similarly, for a U.S. tax-exempt shareholder, there currently is no guidance directly addressing whether or in what circumstances such activities could give rise to UBTI. Moreover, although the Ruling & FAQs address the treatment of hard forks, there continues to be uncertainty with respect to the timing and amount of the income inclusions. While the Ruling & FAQs do not address most situations in which airdrops occur, it is clear from the reasoning of the Ruling & FAQs that the IRS generally would treat an airdrop as a taxable event giving rise to ordinary income.

There can be no assurance that the IRS will not alter its position with respect to digital assets in the future or that a court would uphold the treatment set forth in the Notice the Ruling & FAQs, the 2023 Staking Guidance and the 2025 Revenue Procedure. It is also unclear what additional guidance on the treatment of digital assets for U.S. federal income tax purposes may be issued in the future. Any such alteration of the current IRS positions or additional guidance could result in adverse tax consequences for shareholders and could have an adverse effect on the prices of digital assets, including the price of SUI in the Digital Asset Market, and therefore could have an adverse effect on the value of Shares. Future developments that may arise with respect to digital assets may increase the uncertainty with respect to the treatment of digital assets for U.S. federal income tax purposes. For example, the Notice addresses only digital assets that are “convertible virtual currency,” and it is conceivable that, as a result of a fork, airdrop or similar occurrence, the Trust could hold certain types of digital assets that are not within the scope of the Notice, in the event the Sponsor seeks to change the Trust’s policy with respect to Incidental Rights or IR Virtual Currency, subject to NYSE Arca obtaining regulatory approval from the SEC.

The remainder of this discussion assumes that SUI, and any Incidental Rights and/or IR Virtual Currency that the Trust may hold, is properly treated for U.S. federal income tax purposes as property that may be held as a capital asset and that is not currency for purposes of the provisions of the Code relating to foreign currency gain and loss.

Shareholders are urged to consult their tax advisers regarding the tax consequences of an investment in the Trust and in digital assets in general, including, in the case of shareholders that are generally exempt from U.S. federal income taxation, whether such shareholders may recognize UBTI as a consequence of Staking or the occurrence of a fork, airdrop or similar event.

Tax Consequences to U.S. Holders

As used herein, the term “U.S. Holder” means a beneficial owner of a Share for U.S. federal income tax purposes that is:

•

an individual who is a citizen or resident of the United States for U.S. federal income tax purposes;

•

a corporation, or other entity treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States or of any political subdivision thereof; or

•

an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

Except as specifically noted, the discussion below assumes that each U.S. Holder will acquire all of its Shares on the same date for the same price per Share and solely for cash or solely for SUI that were originally acquired by the U.S. Holder for cash on the same date.

As discussed in the section entitled “Description of Creation and Redemption of Shares,” a U.S. Holder may be able to acquire Shares of the Trust by contributing SUI in-kind to the Trust (either directly or through an Authorized Participant acting as agent of the U.S. Holder). Assuming that the Trust is properly treated as a grantor trust for U.S. federal income tax purposes, such a contribution should not be a taxable event to the U.S. Holder.

For U.S. federal income tax purposes, each U.S. Holder will be treated as owning an undivided interest in the SUI held in the Trust and will be treated as directly realizing its pro rata share of the Trust’s income, gains, losses and deductions (including any Staking income). When a U.S. Holder purchases Shares solely for cash, (i) the U.S. Holder’s initial tax basis in its pro rata share of the SUI held in the Trust will be equal to the amount paid for the Shares and (ii) the U.S. Holder’s holding period for its pro rata share of such SUI will begin on the date of such purchase. When a U.S. Holder acquires Shares in exchange for SUI, (i) the U.S. Holder’s initial tax basis in its pro rata share of the SUI held in the Trust will be equal to the U.S. Holder’s tax basis in the SUI that the U.S. Holder transferred to the Trust and (ii) the U.S. Holder’s holding period for its pro rata share of such SUI generally will include the period during which the U.S. Holder held the SUI that the U.S. Holder transferred to the Trust. The Ruling & FAQs confirm that if a taxpayer acquires tokens of a digital asset at different times and for different prices, the taxpayer has a separate tax basis in each lot of such tokens. Under the Ruling & FAQs, if a U.S. Holder that owns more than one lot of SUI contributes a portion of its SUI to the Trust in exchange for Shares, the U.S. Holder could designate the lot(s) from which such contribution will be made, provided that the U.S. Holder is able to identify specifically which SUI it is contributing and to substantiate its tax basis in that SUI. In general, if a U.S. Holder acquires Shares (i) solely for cash at different prices, (ii) partly for cash and partly in exchange for a contribution of SUI or (iii) in exchange for a contribution of SUI with different tax bases, the U.S. Holder’s share of the Trust’s SUI will consist of separate lots with separate tax bases. In addition, in this situation, the U.S. Holder’s holding period for the separate lots may be different. In addition, any SUI received as Staking Consideration received by the Trust will constitute a separate lot with a separate tax basis and holding period.

Gains or losses from the sale of SUI to fund cash redemptions are expected to be treated as incurred only by the shareholder that is being redeemed. However, when the Trust transfers SUI to the Sponsor as payment of the Sponsor’s Fee or the Sponsor’s Staking Fee, or sells SUI to fund payment of any cash distributions or of any Additional Trust Expenses, each U.S. Holder will be treated as having sold its pro rata share of that SUI for their fair market value at that time (which, in the case of SUI sold by the Trust, generally will be equal to the cash proceeds received by the Trust in respect thereof). As a result, each U.S. Holder will recognize gain or loss in an amount equal to the difference between (i) the fair market value of the U.S. Holder’s pro rata share of the SUI transferred and (ii) the U.S. Holder’s tax basis for its pro rata share of the SUI transferred. Any such gain or loss will be short-term capital gain or loss if the U.S. Holder’s holding period for its pro rata share of the SUI is one year or less and long-term capital gain or loss if the U.S. Holder’s holding period for its pro rata share of the SUI is more than one year. A U.S. Holder’s tax basis in its pro rata share of any SUI transferred by the Trust generally will be determined by multiplying the tax basis of the U.S. Holder’s pro rata share of all of the SUI held in the Trust immediately prior to the transfer by a fraction the numerator of which is the amount of SUI transferred and the denominator of which is the total amount of SUI held in the Trust immediately prior to the transfer. Immediately after the transfer, the U.S. Holder’s tax basis in its pro rata share of the SUI remaining in the Trust will be equal to the tax basis of its pro rata share of the SUI held in the Trust immediately prior to the transfer, less the portion of that tax basis allocable to its pro rata share of the SUI transferred. A U.S. Holder’s receipt of distributions of cash proceeds from the sale of SUI (other than in connection with a redemption) should not, itself, be a taxable event to a U.S. Holder.

As noted above, the IRS has taken the position in the Ruling & FAQs that, under certain circumstances, a hard fork of a digital asset constitutes a taxable event giving rise to ordinary income, and it is clear from the reasoning of the Ruling & FAQs that the IRS generally would treat an airdrop as a taxable event giving rise to ordinary income. As described above, the Sponsor has committed to causing the Trust to abandon all Incidental Rights and IR Virtual Currency to which the Trust otherwise might become entitled. If, however, the Trust were to receive and retain IR Virtual Currency in the future, a U.S. Holder would have a basis in that IR Virtual Currency equal to the amount of income the U.S. Holder recognizes as a result of such fork or airdrop and the U.S. Holder’s holding period for such IR Virtual Currency would begin as of the time it recognizes such income. Similarly, although the IRS has not issued similar guidance with respect to staking, if the Trust receives any Staking Consideration in connection with Staking, it is likely that a U.S. Holder will have a basis in any SUI received as part of such Staking Consideration equal to the amount of income that the U.S. Holder recognizes and the U.S. Holder’s holding period for such Staking Consideration will begin as of the time it recognizes such income.

U.S. Holders’ pro rata shares of the expenses incurred by the Trust will be treated as “miscellaneous itemized deductions” for U.S. federal income tax purposes. As a result, a non-corporate U.S. Holder’s share of these expenses will not be deductible for U.S. federal income tax purposes.

On a sale or other disposition of Shares, a U.S. Holder will be treated as having sold the SUI underlying such Shares. Accordingly, the U.S. Holder generally will recognize gain or loss in an amount equal to the difference between (i) the amount realized on the sale of the Shares and (ii) the portion of the U.S. Holder’s tax basis in its pro rata share of the SUI held in the Trust that is attributable to the Shares that were sold or otherwise subject to a disposition. Such tax basis generally will be determined by multiplying the tax basis of the U.S. Holder’s pro rata share of all of the SUI held in the Trust immediately prior to such sale or other disposition by a fraction the numerator of which is the number of Shares disposed of and the denominator of which is the total number of Shares held by such U.S. Holder immediately prior to such sale or other disposition (such fraction, expressed as a percentage, the “Share Percentage”). If the U.S. Holder’s share of the Trust’s SUI consists of separate lots with separate tax bases and/or holding periods, the U.S. Holder will be treated as having sold the Share Percentage of each such lot. Gain or loss recognized by a U.S. Holder on a sale or other disposition of Shares will generally be short-term capital gain or loss if the U.S. Holder’s holding period for the SUI underlying such Shares is one year or less and long-term capital gain or loss if the U.S. Holder’s holding period for the SUI underlying such Shares is more than one year. The deductibility of capital losses is subject to significant limitations.

If the Trust redeems all or a portion of a U.S. Holder’s Shares in exchange for the underlying SUI represented by the redeemed Shares, such redemption generally will not be a taxable event to the U.S. Holder. The U.S. Holder’s tax basis in the SUI received in the redemption generally will be the same as the U.S. Holder’s tax basis for the portion of its pro rata share of the SUI held in the Trust immediately prior to the redemption that was attributable to the Shares redeemed, determined as described above, and the U.S. Holder’s tax basis in its remaining pro rata portion, if any, of the SUI held in the Trust after the redemption will be equal to the tax basis of its pro rata share of the total amount of the SUI held in the Trust immediately prior to the redemption, less the U.S. Holder’s tax basis in the SUI received in the redemption. The U.S. Holder’s holding period with respect to the SUI received will generally include the period during which the U.S. Holder held the Shares so redeemed. A subsequent sale of the SUI received in such redemption will generally be a taxable event.

After any sale or other disposition of fewer than all of a U.S. Holder’s Shares, the U.S. Holder’s tax basis in its pro rata share of the SUI held in the Trust immediately after the disposition will equal the tax basis in its pro rata share of the total amount of the SUI held in the Trust immediately prior to the disposition, less the portion of that tax basis that is taken into account in determining the

amount of gain or loss recognized by the U.S. Holder on the disposition (or, in the case of a redemption pursuant to an In-Kind Order, the portion of tax basis that is treated as the basis of the SUI received by the U.S. Holder in the redemption).

Any brokerage or other transaction fee incurred by a U.S. Holder in purchasing Shares generally will be added to the U.S. Holder’s tax basis in the underlying assets of the Trust. Similarly, any brokerage fee or other transaction fee incurred by a U.S. Holder in selling Shares generally will reduce the amount realized by the U.S. Holder with respect to the sale.

If the Trust receives Staking Consideration, that Staking Consideration would be reportable to shareholders as taxable income under current IRS guidance.

In the absence of guidance to the contrary, it is possible that any income recognized by a U.S. tax-exempt shareholder as a consequence of Staking, or the occurrence of a hard fork, airdrop or similar event, would constitute UBTI. A tax-exempt shareholder should consult its tax adviser regarding whether such shareholder may recognize some UBTI as a consequence of an investment in Shares.

Tax Consequences to Non-U.S. Holders

As used herein, the term “non-U.S. Holder” means a beneficial owner of a Share for U.S. federal income tax purposes that is not a U.S. Holder. The term “non-U.S. Holder” does not include (i) a nonresident alien individual who is present in the United States for 183 days or more in a taxable year, (ii) a former U.S. citizen or U.S. resident or an entity that has expatriated from the United States; (iii) a person whose income in respect of Shares is effectively connected with the conduct of a trade or business in the United States; or (iv) an entity that is treated as a partnership for U.S. federal income tax purposes. Shareholders described in the preceding sentence should consult their tax advisers regarding the U.S. federal income tax consequences of owning Shares.

A non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax with respect to its share of any gain recognized on the Trust’s transfer of SUI in payment of the Sponsor’s Fee, the Sponsor’s Staking Fee or any Additional Trust Expense or on the Trust’s sale or other disposition of SUI. In addition, assuming that the Trust holds no asset other than SUI, a non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax with respect to any gain it recognizes on a sale or other disposition of Shares. A non-U.S. Holder also will generally not be subject to U.S. federal income or withholding tax with respect to any distribution received from the Trust, whether in cash or in-kind.

Provided that it does not constitute income that is treated as “effectively connected” with the conduct of a trade or business in the United States, U.S.-source FDAP income received, or treated as received, by a non-U.S. Holder will generally be subject to U.S. withholding tax at the rate of 30% (subject to possible reduction or elimination pursuant to an applicable tax treaty and to statutory exemptions such as the portfolio interest exemption). Although the Sponsor has committed to causing the Trust to abandon all Incidental Rights and IR Virtual Currency to which the Trust may become entitled in the future, and although there is no guidance on point, if the Trust were to receive and retain IR Virtual Currency arising from a future fork, airdrop or similar occurrence, it is likely that any ordinary income recognized by a non-U.S. Holder as a result would constitute FDAP income. It is also possible that the receipt of any Staking Consideration by the Trust would constitute FDAP income. It is unclear, however, whether any such FDAP income would be properly treated as U.S.-source or foreign-source FDAP income. Based on the current manner in which the Trust’s Staking activities are undertaken and certain assurances from the Trust’s Staking Providers regarding their connections to the United States, the Trust believes that its income from staking rewards should not be treated as U.S.-source FDAP income. However, that conclusion is not free from doubt under current law due to the lack of direct governing authority, and no assurance can be given that a withholding agent (including a broker through which Shares are held) will not take a contrary position. In addition, changes in law or changes to the Trust’s Staking Arrangements could cause all or a portion of the Trust’s staking rewards to be treated as U.S.-source FDAP income in the future.

A non-U.S. Holder that is a resident of a country that maintains an income tax treaty with the United States may be eligible to claim the benefits of that treaty to reduce or eliminate, or to obtain a partial or full refund of, the 30% U.S. withholding tax on its share of any U.S.-source FDAP income, but only if the non-U.S. Holder’s home country treats the Trust as “fiscally transparent,” as defined in applicable Treasury Regulations.

In order to prevent the possible imposition of U.S. “backup” withholding and (if applicable) to qualify for a reduced rate of withholding tax at source under a treaty, a non-U.S. Holder must comply with certain certification requirements (generally, by delivering a properly executed IRS Form W-8BEN or W-8BEN-E to the relevant withholding agent).

U.S. Information Reporting and Backup Withholding

The Trust or the appropriate broker will file certain information returns with the IRS and provide shareholders with information regarding their annual income (if any) and expenses with respect to the Trust in accordance with applicable Treasury Regulations.

A U.S. Holder will generally be subject to information reporting requirements and backup withholding unless (i) the U.S. Holder is a corporation or other exempt recipient or (ii) in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding. In order to avoid the information reporting and backup withholding requirements, a non-U.S. Holder may have to comply with certification procedures to establish that it is not a U.S. person. The amount of any backup withholding will be allowed as a credit against the shareholder’s U.S. federal income tax liability and may entitle the holder to a refund, provided that the required information is furnished to the IRS.

FATCA

As discussed above, it is unclear whether any ordinary income recognized by a non-U.S. Holder as a result of a fork, airdrop or similar occurrence or Staking Consideration would constitute U.S.-source FDAP income. Provisions of the Code commonly referred to as “FATCA” require withholding of 30% on payments of U.S.-source FDAP income and, subject to the discussion of proposed Treasury Regulations below, of gross proceeds of dispositions of certain types of property that produce U.S.-source FDAP income to, “foreign financial institutions” (which is broadly defined for this purpose and in general includes investment vehicles) and certain other non-U.S. entities unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied, or an exemption applies. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. In addition, regulations proposed by the U.S. Department of the Treasury (the preamble to which indicates that taxpayers may rely on the regulations pending their finalization) would eliminate the requirement under FATCA of withholding on gross proceeds. If FATCA withholding is imposed, a beneficial owner that is not a foreign financial institution generally may obtain a refund of any amounts withheld by filing a U.S. federal income tax return (which may entail significant administrative burden). Shareholders should consult their tax advisers regarding the effects of FATCA on an investment in the Trust.

Item 1A. Risk Factors

The following risks, some of which have occurred and any of which may occur in the future, can have a material adverse effect on our business or financial performance, which in turn can affect the price of the Shares. These are not the only risks we face. There may be other risks we are not currently aware of or that we currently deem not to be material but may become material in the future.

The risk factors below should be read in conjunction with the other information included in this Annual Report on Form 10-K, including the Trust’s financial statements and related notes thereto, and our other filings with the SEC.

Risk Factors Related to Digital Assets

The trading prices of many digital assets, including SUI, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including declines in the trading prices of SUI, could have a material adverse effect on the value of the Shares and the Shares could lose all or substantially all of their value.

The trading prices of many digital assets, including SUI, have experienced extreme volatility throughout their existence and may continue to do so. For instance, following significant increases throughout the majority of 2020, digital asset prices, including SUI, experienced significant volatility throughout 2021 and 2022. This volatility became extreme in November 2022 when FTX Trading Ltd. (“FTX”) halted customer withdrawals. Additionally, on October 10, 2025, it was reported that a sharp decline in digital asset market prices triggered the liquidation of approximately $20 billion in leveraged positions across the digital asset industry. Any similar halting of withdrawals or liquidations across leveraged positions in the digital asset industry in the future could further impact trading prices. See “—Recent developments in the digital asset economy have led to extreme volatility and disruption in digital asset markets, a loss of confidence in participants of the digital asset ecosystem, significant negative publicity surrounding digital assets broadly and market-wide declines in liquidity.” Digital asset prices, including SUI, have continued to fluctuate widely through the date of this Annual Report.

Extreme volatility in the future, including declines in the trading prices of SUI, could have a material adverse effect on the value of the Shares and the Shares could lose all or substantially all of their value. Furthermore, negative perception, a lack of stability and standardized regulation in the digital asset economy may reduce confidence in the digital asset economy and may result in greater volatility in the price of SUI and other digital assets, including a depreciation in value. The Trust is not actively managed and will not take any actions to take advantage, or mitigate the impacts, of volatility in the price of SUI. For additional information that quantifies the volatility of SUI prices and the value of the Shares, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Historical NAV and SUI Prices.”

Furthermore, changes in U.S. political leadership and economic policies may create uncertainty that materially affects the price of SUI and the Trust’s Shares. For example, on March 6, 2025, President Trump signed an Executive Order to establish a Strategic Bitcoin Reserve and a United States Digital Asset Stockpile. Pursuant to this Executive Order, the Strategic Bitcoin Reserve will be capitalized with Bitcoin owned by the U.S. Department of the Treasury that was forfeited as part of criminal or civil asset forfeiture proceedings, and the Secretaries of Treasury and Commerce are authorized to develop budget-neutral strategies for acquiring additional Bitcoin, provided that those strategies impose no incremental costs on American taxpayers. Conversely, the Digital Asset Stockpile will consist of all digital assets other than Bitcoin owned by the U.S. Department of the Treasury that were forfeited in criminal or civil asset forfeiture proceedings, but the U.S. government will not acquire additional assets for the U.S. Digital Asset Stockpile beyond those obtained through such proceedings. The anticipation of a U.S. government-funded strategic cryptocurrency reserve had motivated large-scale purchases of certain digital assets in the expectation of the U.S. government acquiring such digital assets to fund such reserve, and the market price of such digital assets decreased significantly as a result of the ultimate content of the Executive Order. Any similar action or omission by the U.S. federal administration or other government authorities with respect to SUI or other digital assets may negatively and significantly impact the price of SUI and the Trust’s Shares.

Digital assets such as SUI were only introduced within the past two decades, and the medium-to-long term value of the Shares is subject to a number of factors relating to the capabilities and development of blockchain technologies, such as the recency of their development, their dependence on the internet and other technologies, their dependence on the role played by users, developers and validators and the potential for malicious activity. For example, the realization of one or more of the following risks could materially adversely affect the value of the Shares:

•

Digital asset networks and related protocols are in the early stages of development. Given the recency of the development of digital asset networks and related protocols, digital assets and the underlying digital asset networks and related protocols may not function as intended and parties may be unwilling to use digital assets, which would dampen the growth, if any, of digital asset networks and related protocols.

•

The loss of access to a private key required to access a digital asset may be irreversible. If a private key is lost and no backup of the private key is accessible, or if the private key is otherwise compromised, the owner would be unable to access the digital asset corresponding to that private key.

•

Digital asset networks and related protocols are dependent upon the internet. A disruption of the internet or a digital asset network or related protocol, such as the Sui Network, would affect the ability to transfer digital assets, including SUI, and, consequently, their value.

•

The acceptance of software patches or upgrades to a digital asset network by a significant, but not overwhelming, percentage of the users and validators in a digital asset network, such as the Sui Network, could result in a “fork” in such network’s blockchain, resulting in the operation of multiple separate blockchain networks.

•

Digital asset validating operations can consume significant amounts of electricity, which may have a negative environmental impact and give rise to public opinion against allowing, or government regulations restricting, the use of electricity for validating operations. Additionally, validators may be forced to cease operations during an electricity shortage or power outage.

•

Many digital asset networks face significant scaling challenges and are being upgraded with various features to increase the speed and throughput of digital asset transactions. These attempts to increase the volume of transactions may not be effective.

•

The open-source structure of many digital asset network protocols, such as the protocol for the Sui Network, means that developers and other contributors are often not compensated for their contributions in maintaining and developing such protocols. As a result, the developers and other contributors of a particular digital asset may lack a financial incentive to maintain or develop the network or may lack the resources to adequately address emerging issues. Alternatively, some developers may be funded by companies whose interests are at odds with other participants in a particular digital asset network. A failure to properly monitor and upgrade the protocol of the Sui Network could damage that network.

•

Moreover, in the past, flaws in the source code for digital asset networks and related protocols have been exposed and exploited, including flaws that disabled some functionality for users, exposed users’ personal information and/or resulted in the theft of users’ digital assets. The cryptography underlying the Sui Network could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry and quantum computing, could result in such cryptography becoming ineffective. Quantum computing technology is an emerging phenomenon which, because it is still developing, makes it difficult to predict its ultimate effect on the future value of SUI and other digital assets. However, if quantum computing technology is able to advance and significantly increase its capacity relative to the capacity of today’s leading quantum computers, it could potentially undermine the viability of many of the cryptographic algorithms used across the world’s information technology infrastructure, including the cryptographic algorithms used for digital assets like SUI. If quantum computing is able to advance in that way, there is a risk that quantum computing could materially reduce the security assumptions underlying the Sui Network and result in the cryptography underlying the Sui Network becoming ineffective. If such is realized, it could compromise the security of the Sui Network or allow a malicious actor to compromise the wallets holding SUI owned by the Trust or others on the Sui Network, which would result in losses to shareholders. For example, if sufficiently powerful quantum computers are developed, they could use known quantum algorithms to derive private keys from publicly available public keys, potentially allowing malicious actors to forge transaction signatures and misappropriate SUI. There is no guarantee that new quantum-proof architectures will be built and appropriate transitions will be implemented across the network at scale in a timely manner; any such changes could require the achievement of broad consensus within the Sui Network community and may result in a fork (or multiple forks), and there can be no assurance that such consensus would be achieved or the changes implemented successfully. In such a scenario, the Sui Network may not be able to transition to quantum-resistant cryptography in a timely or effective manner. In any of these circumstances, a malicious actor may be able to take the Trust’s SUI, which would adversely affect the value of the Shares. Moreover, functionality of the Sui Network may be negatively affected by such an exploit such that it is no longer attractive to users, thereby dampening demand for SUI. Even if another digital asset other than SUI were affected by similar circumstances, any reduction in confidence in the source code or cryptography underlying digital asset networks and related protocols generally could negatively affect the demand for digital assets and therefore adversely affect the value of the Shares.

Moreover, because digital assets, including SUI, have existed for a short period of time and are continuing to be developed, there may be additional risks to digital asset networks and related protocols that are impossible to predict as of the date of this Annual Report.

Digital assets represent a relatively new and rapidly evolving industry, and the value of the Shares depends on the acceptance of SUI.

The first digital asset, Bitcoin, was launched in 2009. SUI was launched in 2023 and its development is ongoing. In general, digital asset networks, including the Sui Network and related protocols represent a new and rapidly evolving industry that is subject to a variety of factors that are difficult to evaluate. For example, the realization of one or more of the following risks could materially adversely affect the value of the Shares:

•

Digital assets have only recently become selectively accepted as a means of payment by retail and commercial outlets, but there is no meaningful degree of use of SUI as a means of payment by retail or commercial outlets. Banks and other established financial institutions, whether voluntarily or in response to regulatory feedback, may refuse to process funds for SUI transactions; process wire transfers to or from Digital Asset Trading Platforms, SUI-related companies or service providers; or maintain accounts for persons or entities transacting in SUI. As a result, the prices of SUI are largely determined by speculators and validators, thus contributing to price volatility that makes retailers less likely to accept SUI in the future. While the use of other digital assets, such as Bitcoin, to purchase goods and services from commercial or service businesses is developing, SUI has not yet been accepted in the same manner because it has a slightly different purpose than Bitcoin.

•

Banks may not provide banking services, or may cut off banking services, to businesses that provide digital asset-related services or that accept digital assets as payment, which could dampen liquidity in the market and damage the public perception of digital assets generally or any one digital asset in particular, such as SUI, and their or its utility as a payment system, which could decrease the price of digital assets generally or individually.

•

The prices of digital assets may be determined on a relatively small number of Digital Asset Trading Platforms by a relatively small number of market participants, many of whom are speculators or those intimately involved with the issuance of such digital assets, such as validators or developers, which could contribute to price volatility that makes retailers less likely to accept digital assets in the future.

•

Certain privacy-preserving features have been or are expected to be introduced to a number of digital asset networks. If any such features are introduced to the Sui Network, any trading platforms or businesses that facilitate transactions in SUI may be at an increased risk of criminal or civil lawsuits, or of having banking services cut off if there is a concern that these features interfere with the performance of anti-money laundering duties and economic sanctions checks.

•

Users, developers and validators may switch to or adopt certain digital asset networks or protocols at the expense of their engagement with other digital asset networks and protocols, which may negatively impact those networks and protocols, including the Sui Network.

The Sui protocol was only recently conceived, and the Sui Network or its underlying technologies may not function as intended, which could have an adverse impact on the value of SUI and an investment in the Shares.

Components of the Sui protocol were first conceived in 2017 by Evan Cheng, Adeniyi Abiodun, Sam Blackshear, George Danezis, and Kostas Chalkias, continuing research performed while employed by Meta on the Diem (previously called Libra) project. To achieve consensus among validators, the network historically used a dual-layer design consisting of “Narwhal,” a data-availability layer, and “Bullshark,” a consensus protocol. However, in July 2024, the Sui Network introduced the “Mysticeti” consensus mechanism to replace Bullshark, improving transaction latency and throughput while continuing to use Narwhal for data dissemination. This configuration enables the Sui Network to verify and execute many transactions in parallel, rather than sequentially like in prominent blockchains like Bitcoin and Ethereum. The Sui protocol, Narwhal and Mysticeti are new technologies that are not widely used and may not function as intended. For example, they may require more specialized equipment to participate in the network and fail to attract a significant number of users. In addition, there may be flaws in the cryptography underlying Narwhal and Mysticeti, including flaws that affect functionality of the Sui Network or make the network vulnerable to attack. The development of the Sui Network is ongoing and any further disruption could have a material adverse effect on the value of SUI and an investment in the Shares.

For example, on November 21, 2024, the Sui Network experienced a significant disruption, later attributed to a type of denial of service attack, and was offline for over 2 hours. The development of the Sui Network is ongoing and any further disruption could have a material adverse effect on the value of SUI and an investment in the Shares.

Smart contracts are a new technology and ongoing development may magnify initial problems, cause volatility on the networks that use smart contracts and reduce interest in them, which could have an adverse impact on the value of SUI.

Smart contracts are programs that run on a blockchain that execute automatically when certain conditions are met. Since smart contracts typically cannot be stopped or reversed, vulnerabilities in their programming can have damaging effects. For example, in June 2016, a vulnerability in the smart contracts underlying The DAO, a distributed autonomous organization for venture capital funding, allowed an attack by a hacker to syphon approximately $60 million worth of Ether from The DAO’s accounts into a segregated account.

In the aftermath of the theft, certain developers and core contributors pursued a “hard fork” of the Ethereum network in order to erase any record of the theft. Despite these efforts, the price of Ether dropped approximately 35% in the aftermath of the attack and subsequent hard fork. In addition, in July 2017, a vulnerability in a smart contract for a multi-signature wallet software developed by Parity led to a $30 million theft of Ether, and in November 2017, a new vulnerability in Parity’s wallet software led to roughly $160 million worth of Ether being indefinitely frozen in an account. In another example, in February 2022, a vulnerability in a smart contract for Wormhole, a bridge between the Ethereum and Solana networks led to a $320 million theft of Ether. While persons associated with Solana Labs and/or the Solana Foundation are understood to have played a key role in bringing the network back online, the broader community also played a key role, as Solana validators coordinated to upgrade and restart the network. Other smart contracts, such as bridges between blockchain networks and DeFi protocols have also been manipulated, exploited or used in ways that were not intended or envisioned by their creators such that attackers syphoned over $3.8 billion worth of digital assets from smart contracts in 2022. Initial problems and continued problems with the development, design and deployment of smart contracts may have an adverse effect on the value of SUI, which could have a negative impact on the value of the Shares.

Changes in the governance of a digital asset network or protocol may not receive sufficient support from users and validators, which may negatively affect that digital asset network’s or protocol’s ability to grow and respond to challenges.

The governance of some digital asset networks and protocols, such as the Sui Network, is generally by voluntary consensus and open competition. For such networks and protocols, there may be a lack of consensus or clarity on that network’s or protocol’s governance, which may stymie such network’s or protocol’s utility, adaptability and ability to grow and face challenges.

The foregoing notwithstanding, the underlying software for some digital asset networks and protocols, such as the Sui Network, is informally or formally managed or developed by a group of core developers that propose amendments to the relevant network’s or protocol’s source code. Core developers’ roles may evolve over time, generally based on self-determined participation. If a significant majority of users and validators were to adopt amendments to a decentralized network based on the proposals of such core developers, such network would be subject to new source code that may adversely affect the value of the relevant digital asset.

As a result of the foregoing, it may be difficult to find solutions or marshal sufficient effort to overcome any future problems, especially long-term problems, on digital asset networks.

Digital asset networks face significant scaling challenges and efforts to increase the volume and speed of transactions may not be successful.

Many digital asset networks face significant scaling challenges due to the fact that public, permissionless blockchains generally face a tradeoff between security and scalability. One means through which digital asset networks that utilize public, permissionless blockchains achieve security is decentralization, meaning that no intermediary is responsible for securing and maintaining these systems. For example, a greater degree of decentralization of a public, permissionless blockchain generally means a given digital asset network is less susceptible to manipulation or capture. In practice, this typically means that every single node on a given digital asset network is responsible for securing the system by processing every transaction and maintaining a copy of the entire state of the network. As a result, a digital asset network that utilizes a public, permissionless blockchain may be limited in the number of transactions it can process by the computing capabilities of each single fully participating node. Many developers are actively researching and testing scalability solutions for public blockchains that do not necessarily result in lower levels of security or decentralization, such as off-chain payment channels and Layer 2 networks. Off-chain payment channels would allow parties to transact without requiring the full processing power of a blockchain. Layer 2 networks can increase the scalability of a blockchain, by allowing users to transact on a second blockchain deployed on top of a “Layer 1” network.

The Sui Network can reportedly handle hundreds of thousands of transactions per second, though as of December 31, 2025, the network reportedly processed approximately 500 transactions per second at its peak. In an effort to increase the volume of transactions that can be processed on a given digital asset network, many digital assets are being upgraded with various features to increase the speed and throughput of digital asset transactions.

As corresponding increases in throughput lag behind growth in the use of digital asset networks, average fees and settlement times may increase considerably. Since inception, SUI transaction fees are typically below 10 SUI per transaction though have been recorded higher than 600 SUI per transaction during periods of high congestion. Increased fees and decreased settlement speeds could preclude certain uses for SUI (e.g., micropayments), and could reduce demand for, and the price of, SUI, which could adversely impact the value of the Shares.

There is no guarantee that any of the mechanisms in place or being explored for increasing the scale of settlement or throughput of Sui Network transactions will be effective, or how long these mechanisms will take to become effective, which could adversely impact the value of the Shares.

Digital asset networks are developed by a diverse set of contributors and the perception that certain high-profile contributors will no longer contribute to the network could have an adverse effect on the market price of the related digital asset.

Digital asset networks and related protocols are often developed by a diverse set of contributors, but are also often developed by identifiable and high-profile contributors. The perception that certain high-profile contributors may no longer contribute to the applicable digital asset network or protocol may have an adverse effect on the market price of any related digital assets. For example, in June 2017, an unfounded rumor circulated that Ethereum protocol developer Vitalik Buterin had died. Following the rumor, the price of Ether decreased approximately 20% before recovering after Buterin himself dispelled the rumor. Some have speculated that the rumor led to the decrease in the price of Ether. In the event a high-profile contributor to the Sui Network is perceived as no longer contributing to the Sui Network due to death, retirement, withdrawal, incapacity, or otherwise, whether or not such perception is valid, it could negatively affect the price of SUI, which could adversely impact the value of the Shares.

Digital assets may have concentrated ownership and large sales or distributions by holders of such digital assets, or any ability to participate in or otherwise influence a digital asset’s underlying network, could have an adverse effect on the market price of such digital asset.

As of December 31, 2025, the largest 100 SUI wallets held approximately 16% of the SUI in circulation. Moreover, it is possible that other persons or entities control multiple wallets that collectively hold a significant amount of SUI, even if they individually only hold a small amount, and it is possible that some of these wallets are controlled by the same person or entity. In particular, in connection with the launch of the Sui Network, a significant portion of the total initial SUI supply was allocated to early contributors, Mysten treasury, and the community reserve, subject to various release schedules and terms of use. As a result of this concentration of ownership, large sales or distributions by such holders could have an adverse effect on the market price of SUI. Likewise, the Sui Network’s development has been historically and is currently overseen by the Sui Foundation, Mysten, and other core developers. As such, the Sui Foundation, Mysten, and core developers are able to influence the network.

Moreover, it is possible that a group of SUI holders that together control more than a substantial amount of outstanding SUI are in fact part of the initial or current core developer group, or are otherwise influential members of the Sui community. To the extent that the initial or current core developer groups also control higher than a threshold of outstanding SUI necessary for an attack, as some believe, the risk of this particular group of users causing the Sui Network to adopt updates to the core protocol that this particular group wants to be implemented will be even greater, and should this materialize, it may adversely affect the value of the Shares.

Validators may suffer losses due to Staking, or Staking may prove unattractive to validators, which could adversely affect the Sui Network.

Staking on the Sui Network requires SUI to be locked by the underlying blockchain network in “objects,” or data units on the Sui Network that hold assets and are managed by the protocol rather than the user. If the Sui Network source code or protocol were to fail to behave as expected, suffer cybersecurity attacks or hacks, experience security issues, or encounter other problems, such transferred (i.e., staked) SUI may be irretrievably lost. In addition, the Sui Network’s underlying protocol dictates requirements for participation in validation activity, and may impose penalties, if the relevant activities are not performed correctly. In addition, the Sui Network dictate requirements for participation in validation activity, and may impose penalties, if the relevant activities are not performed correctly. The Sui Network’s penalties (i.e., “slashing”) may be imposed if a validator commits malicious acts related to the validation of blocks with invalid transactions. Although the Sui Network does not implement slashing of staked principal, the protocol may impose penalties—such as loss of rewards or removal from the validator set—if a validator commits malicious acts or fails to perform required validation activities.

SUI is inaccessible while it is staked and as part of the “activating” and “de-activating” or “cooling down” processes of staking. “Activation” is the funding of a validator to be included in the active set, thereby allowing the validator to participate in the Sui Network’s proof-of-stake consensus protocol. “De-activating” is the request to exit from the active set and no longer participate in the Sui Network’s proof-of-stake consensus protocol. As part of these “activating” and “de-activating” processes of staking on the Sui Network, any staked SUI will be inaccessible for a period of time, denominated in “epochs.” On the Sui Network, epochs are targeted to last approximately 24 hours, though actual epoch durations may vary slightly due to validator coordination and other timing effects inherent in the network’s consensus protocol. De-activation typically completes when the current epoch ends, which may be up to one full epoch after the request is submitted. Once the de-activation period ends, the stake becomes fully inactive and can be withdrawn. As a result, the elapsed time between a de-activation request and withdrawal availability may differ depending on (i) when the request is submitted and (ii) the slight variation in epoch duration.

The Sui Network requires the payment of gas fees in SUI, and such fees can become significant as the amount and complexity of the transaction grows, depending on the degree of network congestion and the price of SUI. Any cybersecurity attacks, security issues, hacks, penalties, slashing events, or other problems could damage validators’ willingness to participate in validation, discourage existing and future validators from serving as such, and adversely impact the Sui Network’s adoption or the price of SUI. Any disruption of validation on the Sui Network could interfere with network operations and cause the Sui Network to be less attractive to users and application developers than competing blockchain networks, which could cause the price of SUI to decrease.

The Sponsor anticipates that it will engage in staking with respect to all of the Trust’s SUI at all times, except (i) as necessary to pay the Sponsor's Fee and the Sponsor's Staking Fee, (ii) as necessary to pay any additional Trust expenses, (iii) as necessary to satisfy existing and reasonably foreseen potential redemption requests (assuming the Trust is then permitted to operate an ongoing redemption program) as determined by the Sponsor, (iv) as necessary to reduce the SUI obtained by the Trust as Native Staking Consideration to cash for distribution at regular intervals, (v) as necessary to reduce the SUI obtained by the Trust as Native Staking Consideration to cash in connection with the Trust's liquidation, (vi) as necessary to take protective actions in respect of vulnerabilities in the source code or cryptography underlying the Sui Network and/or its proof-of-stake protocol, its staking smart contracts or its validator client software, (vii) if the Custodian discontinues its arrangements with the Trust and such discontinuance affects the Trust's SUI, for so long as is reasonably necessary to re-establish those arrangements or to establish similar arrangements with other parties, (viii) if the Custodian discontinues its arrangements with the Staking Provider and such discontinuance affects the Trust's SUI, for so long as is reasonably necessary to re-establish those arrangements or to establish similar arrangements with other parties, (ix) in the event of a change in applicable law or regulation, (x) as necessary to maintain a Liquidity Sleeve (as defined herein), (xi) as necessary pursuant to a “contingent liquidity arrangement” within the meaning of Section 6.02(12) of IRS Revenue Procedure 2025-31 or (xii) in accordance with any other exception that is expressly contemplated by an opinion, ruling or tax guidance that satisfies the Staking Condition. All SUI received by the Trust in connection with the creation of new Shares, or as Native Staking Consideration, would also be staked upon receipt by the Trust, unless one or more of the exceptions described in clauses (i)-(xii) above applies. Under the Trust Agreement, the Trust's Staking Arrangements also must satisfy certain other requirements derived from IRS Revenue Procedure 2025-31. Moreover, any staked SUI which must be un-staked in order to fulfill a distribution in connection with a redemption (to the extent such distribution cannot be fulfilled utilizing the portion of the Trust's SUI that has not been staked, or through another mechanism to manage liquidity in connection with Redemption Orders contemplated by an opinion of a Tax Advisor, a Tax Ruling or Tax Guidance that satisfies the Staking Condition) will be un-staked only after the redemption request is approved by the Trust, the Sponsor executes an un-stake or withdrawal transaction through the Custodian, and such transaction is processed by the Sui Network.

As of the date of this filing, the Sponsor generally seeks to stake as much of the Trust’s SUI as is practicable (i.e., up to 100%) at all times, with the remainder of the Trust’s SUI remaining unstaked in order to address the various exceptions and other considerations described herein. The percentage of the Trust’s SUI that is staked each day will be reported the following day at 4:00 p.m., New York time, on etfs.grayscale.com/gsui.

If the digital asset reward or transaction fees for recording transactions on the Sui Network are not sufficiently high to incentivize validators, or if certain jurisdictions continue to limit or otherwise regulate validating activities, validators may cease expanding validating power or demand high transaction fees, which could negatively impact the value of SUI and the value of the Shares.

If the digital asset awards or transaction fees for recording transactions on the Sui Network are not sufficiently high to incentivize validators, or if certain jurisdictions continue to limit or otherwise regulate validating activities, validators may cease expending validating power to validate blocks and confirmations of transactions on the Blockchain could be slowed. For example, the realization of one or more of the following risks could materially adversely affect the value of the Shares:

•

Over the past several years, digital asset validating operations have evolved from individual users validating with computer processors, graphics processing units and first-generation application specific integrated circuit machines to “professionalized” validating operations using proprietary hardware or sophisticated machines. If the profit margins of digital asset validating operations are not sufficiently high, digital asset validators are more likely to immediately sell digital assets earned by validating, resulting in an increase in liquid supply of that digital asset, which would generally tend to reduce that digital asset’s market price.

•

A reduction in digital assets staked by validators on the Sui Network could increase the likelihood of a malicious actor or botnet obtaining control. See “—If a malicious actor or botnet obtains control of more than 50% of the validating power on the Sui Network, or otherwise obtains control over the Sui Network through its influence over core developers or otherwise, such actor or botnet could manipulate the Blockchain to adversely affect the value of the Shares or the ability of the Trust to operate.”

•

Validators have historically accepted relatively low transaction confirmation fees on most digital asset networks. If validators demand higher transaction fees for recording transactions in the Blockchain, the cost of using SUI may increase and the marketplace may be reluctant to accept SUI as a means of payment. Alternatively, validators could collude in an anti-competitive manner to reject low transaction fees on the Sui Network and force users to pay higher fees, thus reducing the attractiveness of the Sui Network. Higher transaction confirmation fees resulting through collusion or otherwise may adversely affect the attractiveness of the Sui Network, the value of SUI and the value of the Shares.

•

To the extent that any validators cease to record transactions that do not include the payment of a transaction fee in validated blocks or do not record a transaction because the transaction fee is too low, such transactions will not be recorded on the SUI Blockchain until a block is validated by a validator who is willing to accept a lower fee. Any widespread delays in the recording of transactions could result in a loss of confidence in the digital asset network.

•

During the course of ordering transactions and validating blocks, validators may be able to prioritize certain transactions in return for increased transaction fees, an incentive system known as “Maximal Extractable Value” or MEV. For example, in blockchain networks that facilitate DeFi protocols in particular, such as the Sui Network, users may attempt to gain an advantage over other users by increasing offered transaction fees. Certain software solutions, such as Flashbots, have been developed which facilitate validators in capturing MEV produced by these increased fees. The MEV incentive system may lead to an increase in transaction fees on the Sui Network, which may diminish its use. Users or other stakeholders on the Sui Network could also view the existence of MEV as unfair manipulation of decentralized digital asset networks, and refrain from using DeFi protocols or the Sui Network generally. In addition, it’s possible regulators or legislators could enact rules which restrict the use of MEV, which could diminish the popularity of the Sui Network among users and validators. Any of these or other outcomes related to MEV may adversely affect the value of SUI and the value of the Shares.

Proof-of-stake blockchains are a relatively recent innovation, and have not been subject to as widespread use or adoption over as long of a period of time as traditional proof-of-work blockchains.

Certain digital assets, such as bitcoin, use a “proof-of-work” consensus algorithm. The genesis block on the Bitcoin blockchain was mined in 2009, and Bitcoin’s blockchain has been in operation since then. Many newer blockchains enabling smart contract functionality, including the current Ethereum Network following the completion of the Merge in 2022, use a newer consensus algorithm known as “proof-of-stake.” While their proponents believe that they may have certain advantages, the “proof-of-stake” consensus mechanisms and governance systems underlying many newer blockchain protocols, including the Sui Network, and their associated digital assets – including the SUI held by the Trust – have not been tested at scale over as long of a period of time or subject to as widespread use or adoption as, for example, Bitcoin’s proof-of-work consensus mechanism has. This could lead to these blockchains, and their associated digital assets, having undetected vulnerabilities, structural design flaws, suboptimal incentive structures for network participants (e.g., validators), technical disruptions, or a wide variety of other problems, any of which could cause these blockchains not to function as intended, lead to outright failure to function entirely causing a total outage or disruption of network activity, or to suffer other operational problems or reputational damage, leading to a loss of users or adoption or a loss in value of the associated digital assets, including the Trust’s assets. Over the long term, there can be no assurance that the proof-of-stake blockchain on which the Trust’s assets rely will achieve widespread scale or adoption or perform successfully; any failure to do so could negatively impact the value of the Trust’s assets.

If a malicious actor or botnet obtains control of a sufficient amount of the validating power on the Sui Network, or otherwise obtains control over the Sui Network through its influence over core developers or otherwise, such actor or botnet could manipulate the Blockchain to adversely affect the value of the Shares or the ability of the Trust to operate.

All networked systems are vulnerable to various types of attacks. As with any computer network, the Sui Network could be attacked. For example, the Sui Network is currently vulnerable to several types of attacks, including:

•

“33% attack” where, if a validator or group of validators were to gain control of more than 33% of the total staked SUI on the Sui Network, a malicious actor could temporarily impede or delay block confirmation or even cause a temporary fork in the blockchain.

•

“50% attack” where, if a validator or group of validators acting in concert were to gain control of more than 50% of the total staked SUI on the Sui Network, a malicious actor would be able to gain full control of the Sui Network and the ability to manipulate the blockchain on a forward-looking basis, including censoring transactions following the achievement of threshold, double-spending and fraudulent block propagation, while the attacker maintains the threshold. In theory, the minority non-attackers might reach social consensus to reject blocks proposed by the malicious majority attacker, reducing the attacker’s ability to engage in malicious activity, but there can be no assurance this would happen or that non-attackers would be able to coordinate effectively.

•

“>66% attack” where, if a validator or group of validators acting in concert were to gain control of more than 66% of the total staked SUI on the Sui Network, a malicious actor could permanently and irreversibly manipulate the blockchain, including censorship, double-spending and fraudulent block propagation, both on a forward-and backward-looking basis. The attacker could unilaterally finalize their preferred chain without the votes of any other stakers, and could also reverse past finalized blocks. The Sui Network’s proof-of-stake consensus mechanism requires a 2/3 supermajority of validators who have staked SUI to vote in favor in order to finalize transactions and add blocks to the Sui Blockchain.

Although there are no known reports of malicious control of the Sui Network, if groups of coordinating or connected SUI holders that together have more than 50% of outstanding SUI were to stake that SUI and run validators, they could exert authority over the validation of SUI transactions. This risk is heightened if a substantial amount of the validating power on the network falls within the jurisdiction of a single governmental authority. If network participants, including the core developers and the administrators of validating pools, do not act to ensure greater decentralization of Sui Network validators, the feasibility of a malicious actor obtaining control of the validating power on the Sui Network will increase, which may adversely affect the value of SUI and the value of the Shares.

A malicious actor may also obtain control over the Sui Network through its influence over core developers by gaining direct control over a core developer or an otherwise influential programmer. The less that the Sui ecosystem grows, the greater the possibility that a malicious actor may be able to maliciously influence the Sui Network in this manner. Moreover, it is possible that a group of SUI holders that together control more than a substantial amount of outstanding SUI are in fact part of the initial or current core developer group, or are otherwise influential members of the Sui community. To the extent that the initial or current core developer groups also control higher than a threshold of outstanding SUI necessary for an attack, as some believe, the risk of this particular group of users causing the Sui Network to adopt updates to the core protocol that this particular group wants to be implemented will be even greater, and should this materialize, it may adversely affect the value of the Shares.

If validators exit the Sui Network, it could increase the likelihood of a malicious actor obtaining control.

Validators exiting the network could make the Sui Network more vulnerable to a malicious actor obtaining control of a large percentage of staked SUI, which might enable them to manipulate the Blockchain by censoring or manipulating specific transactions, as discussed previously. If the Blockchain suffers such an attack, the price of SUI could be negatively affected, and a loss of confidence in the Sui Network could result. Any reduction in confidence in the transaction confirmation process or staking power of the Sui Network may adversely affect an investment in the Trust.

A temporary or permanent “fork” or a “clone” could adversely affect the value of the Shares.

The Sui Network operates using open-source protocols, meaning that any user can download the software, modify it and then propose that the users and validators of SUI adopt the modification. When a modification is introduced and a substantial majority of users and validators consent to the modification, the change is implemented and the network remains uninterrupted. However, if less than a substantial majority of users and validators consent to the proposed modification, and the modification is not compatible with the software prior to its modification, the consequence would be what is known as a “hard fork” of the Sui Network, with one group running the pre-modified software and the other running the modified software. The effect of such a fork would be the existence of two versions of Sui running in parallel, yet lacking interchangeability. For example, in September 2022, the Ethereum network transitioned to a proof-of-stake model, in an upgrade referred to as the “Merge.” Following the Merge, a hard fork of the Ethereum network occurred, as certain Ethereum miners and network participants planned to maintain the proof-of-work consensus mechanism that was removed as part of the Merge. This version of the network was rebranded as “Ethereum Proof-of-Work.”

Forks may also occur as a digital asset network community’s response to a significant security breach. For example, in July 2016, Ethereum “forked” into Ethereum and a new digital asset, Ethereum Classic, as a result of the Ethereum network community’s response to a significant security breach. In June 2016, an anonymous hacker exploited a smart contract running on the Ethereum network to syphon approximately $60 million of Ether held by The DAO, a distributed autonomous organization, into a segregated account. In response to the exploit, most participants in the Ethereum community elected to adopt a “fork” that effectively reversed the exploit. However, a minority of users continued to develop the original blockchain, referred to as “Ethereum Classic” with the digital asset on that blockchain now referred to as ETC. ETC now trades on several Digital Asset Trading Platforms. A fork may also occur as a result of an unintentional or unanticipated software flaw in the various versions of otherwise compatible software that users run. Such a fork could lead to users and validators abandoning the digital asset with the flawed software. It is possible, however, that a substantial number of users and validators could adopt an incompatible version of the digital asset while resisting community-led efforts to merge the two chains. This could result in a permanent fork, as in the case of Ethereum and Ethereum Classic.

Furthermore, a hard fork can lead to new security concerns. For example, when the Ethereum and Ethereum Classic networks split in July 2016, replay attacks, in which transactions from one network were rebroadcast to nefarious effect on the other network, plagued Ethereum trading platforms through at least October 2016. An Ethereum trading platform announced in July 2016 that it had lost 40,000 Ethereum Classic, worth about $100,000 at that time, as a result of replay attacks. Similar replay attack concerns occurred in connection with the Bitcoin Cash and Bitcoin Satoshi’s Vision networks split in November 2018. Another possible result of a hard fork is an inherent decrease in the level of security due to significant amounts of validating power remaining on one network or migrating instead to the new forked network. After a hard fork, it may become easier for an individual validator or validating pool’s validating power to exceed 50% of the validating power of a digital asset network that retained or attracted less validating power, thereby making digital asset networks that rely on proof-of-stake more susceptible to attack.

Digital asset networks and related protocols may also be cloned. Unlike a fork of a digital asset network, which modifies an existing blockchain, and results in two competing digital asset networks, each with the same genesis block, a “clone” is a copy of a protocol’s codebase, but results in an entirely new blockchain and new genesis block. Tokens are created solely from the new “clone” network and, in contrast to forks, holders of tokens of the existing network that was cloned do not receive any tokens of the new network. A “clone” results in a competing network that has characteristics substantially similar to the network it was based on, subject to any changes as determined by the developer(s) that initiated the clone.

A hard fork may adversely affect the price of SUI at the time of announcement or adoption. For example, the announcement of a hard fork could lead to increased demand for the pre-fork digital asset, in anticipation that ownership of the pre-fork digital asset would entitle holders to a new digital asset following the fork. The increased demand for the pre-fork digital asset may cause the price of the

digital asset to rise. After the hard fork, it is possible the aggregate price of the two versions of the digital asset running in parallel would be less than the price of the digital asset immediately prior to the fork. Furthermore, while the Trust would be entitled to both versions of the digital asset running in parallel, the Sponsor will, as permitted by the terms of the Trust Agreement, determine which version of the digital asset is generally accepted as the Sui Network and should therefore be considered the appropriate network for the Trust’s purposes, and there is no guarantee that the Sponsor will choose the digital asset that is ultimately the most valuable fork. Either of these events could therefore adversely impact the value of the Shares. For example, following the DAO hack in July 2016, holders of Ethereum voted on-chain to reverse the hack, effectively causing a hard fork. For the days following the vote, the price of Ethereum rose from $11.65 on July 15, 2016 to $14.66 on July 21, 2016, the day after the first Ethereum Classic block was mined. A clone may also adversely affect the price of SUI at the time of announcement or adoption. For example, on November 6, 2016, Rhett Creighton, a Zcash developer, cloned the Zcash network to launch Zclassic, a substantially identical version of the Zcash network that eliminated the Founders’ Reward. For the days following the date the first Zclassic block was mined, the price of ZEC fell from $504.57 on November 5, 2016 to $236.01 on November 7, 2016 in the midst of a broader sell off of ZEC beginning immediately after the Zcash network launch on October 28, 2016. A clone may also adversely affect the price of SUI at the time of announcement or adoption.

A future fork in or clone of the Sui Network could adversely affect the value of the Shares or the ability of the Trust to operate.

In the event of a hard fork of the Sui Network, the Sponsor will, if permitted by the terms of the Trust Agreement, use its discretion to determine which network should be considered the appropriate network for the Trust’s purposes, and in doing so may adversely affect the value of the Shares.

In the event of a hard fork of the Sui Network, the Sponsor will, as permitted by the terms of the Trust Agreement, use its discretion to determine, in good faith, which digital asset network, among a group of incompatible forks of the Sui Network, is generally accepted as the Sui Network and should therefore be considered the appropriate digital asset network for the Trust’s purposes. The Sponsor will base its determination on a variety of then relevant factors, including, but not limited to, the Sponsor’s beliefs regarding expectations of the core developers of SUI, users, services, businesses, validators and other constituencies, as well as the actual continued acceptance of, validating power on, and community engagement with, the Sui Network. There is no guarantee that the Sponsor will choose the digital asset network or digital asset that is ultimately the most valuable fork, and the Sponsor’s decision may adversely affect the value of the Shares as a result. The Sponsor may also disagree with shareholders, security vendors and the Index Provider on what is generally accepted as SUI and should therefore be considered “SUI” for the Trust’s purposes, which may also adversely affect the value of the Shares as a result.

In the event of a hard fork of the Sui Network, the Custodian’s operations may be interrupted or subject to additional security risks that could disrupt the Trust’s ability to process creations and redemptions of Shares or otherwise threaten the security of the Trust’s SUI holdings.

In the event of a hard fork of the Sui Network, the Custodian may temporarily halt the ability of customers (including the Trust) to deposit, withdraw or transfer SUI on the Custodian’s platform. Such a delay may be intended to permit the Custodian to assess the resulting versions of the Sui Network, to determine how best to securely “split” the SUI from the forked asset, and to prevent malicious users from conducting “replay attacks” (i.e., broadcasting transactions on both versions of the forked networks to put Custodian assets at risk). As a result, the Trust is likely to suspend creations and redemptions during a period in which the Custodian’s operations are halted.

In addition, any losses experienced by the Custodian due to a hard fork, including due to replay attacks or technological errors in assessing the fork, could have a materially adverse impact on an investment in the Shares.

Any name change and any associated rebranding initiative by the core developers of SUI may not be favorably received by the digital asset community, which could negatively impact the value of SUI and the value of the Shares.

From time to time, digital assets may undergo name changes and associated rebranding initiatives. For example, Bitcoin Cash may sometimes be referred to as Bitcoin ABC in an effort to differentiate itself from any Bitcoin Cash hard forks, such as Bitcoin Satoshi’s Vision, and in the third quarter of 2018, the team behind ZEN rebranded and changed the name of ZenCash to “Horizen.” We cannot predict the impact of any name change and any associated rebranding initiative on the Sui Network or SUI. After a name change and an associated rebranding initiative, a digital asset may not be able to achieve or maintain brand name recognition or status that is comparable to the recognition and status previously enjoyed by such digital asset. The failure of any name change and any associated rebranding initiative by a digital asset may result in such digital asset not realizing some or all of the anticipated benefits contemplated by the name change and associated rebranding initiative, and could negatively impact the value of SUI and the value of the Shares.

If the Sui Network is used to facilitate illicit activities, businesses that facilitate transactions in SUI could be at increased risk of criminal or civil lawsuits, or of having services cut off, which could negatively affect the price of SUI and the value of the Shares.

Digital asset networks have in the past been, and may continue to be, used to facilitate illicit activities. If the Sui Network is used to facilitate illicit activities, businesses that facilitate transactions in SUI could be at increased risk of potential criminal or civil lawsuits, or of having banking or other services cut off, if there is a concern that certain smart contracts on the Sui Network could interfere with the performance of anti-money laundering activities and economic sanctions checks. There is also a risk that Digital Asset Trading Platforms may remove SUI from their platforms as a result of these concerns. Other service providers of such businesses may also cut off services if there is a concern that the Sui Network is being used to facilitate crime. Any of the aforementioned occurrences could increase regulatory scrutiny of the Sui Network and/or adversely affect the price of SUI, the attractiveness of the Sui Network and an investment in the Shares of the Trust.

When the Trust and the Sponsor, acting on behalf of the Trust, sell or deliver, as applicable, SUI or, subject to NYSE Arca obtaining regulatory approval from the SEC, Incidental Rights and/or IR Virtual Currency, they generally do not transact directly with counterparties other than the Authorized Participant, a Liquidity Provider or other similarly eligible financial institutions that are subject to federal and state licensing requirements and maintain practices and policies designed to comply with AML and KYC regulations. When an Authorized Participant or a Liquidity Provider sources SUI in connection with the creation of the Shares or facilitates transactions in SUI at the direction of the Trust or the Sponsor, it directly faces its counterparty and, in all instances, the Authorized Participant or the Liquidity Provider, as applicable, follow policies and procedures designed to ensure that it knows the identity of its counterparty. The Authorized Participant is a registered broker-dealer and therefore subject to AML and countering the financing of terrorism obligations under the Bank Secrecy Act as administered by FinCEN and further overseen by the SEC and FINRA.

In accordance with its regulatory obligations, the Authorized Participant, or the Liquidity Provider, conducts customer due diligence and enhanced due diligence on its counterparties, which enables it to determine each counterparty’s AML and other risks and assign an appropriate risk rating.

As part of its counterparty onboarding process, each of the Authorized Participant and the Liquidity Provider uses third-party services to screen prospective counterparties against various watch lists, including the Specially Designated Nationals List of the Treasury Department Office of Foreign Assets Control (“OFAC”) and countries and territories identified as non-cooperative by the Financial Action Task Force. If the Sponsor, the Trust, the Authorized Participant or the Liquidity Provider were nevertheless to transact with such a sanctioned entity, the Sponsor, the Trust, the Authorized Participant and the Liquidity Provider would be at increased risk of potential criminal or civil lawsuits.

Risk Factors Related to the Digital Asset Markets

In the past and through the date of this Annual Report, digital asset prices have experienced significant fluctuations, leading to volatility and disruption in the digital asset markets and financial difficulties for several prominent industry participants, including Digital Asset Trading Platforms, hedge funds and lending platforms. For example, in the first half of 2022, digital asset lenders Celsius Network LLC and Voyager Digital Ltd. and digital asset hedge fund Three Arrows Capital each entered into insolvency proceedings. This resulted in a loss of confidence in participants in the digital asset ecosystem, negative publicity surrounding digital assets more broadly and market-wide declines in digital asset trading prices and liquidity.

Thereafter, in November 2022, FTX, the third largest Digital Asset Trading Platform by volume at the time, halted customer withdrawals amid rumors of the company’s liquidity issues and likely insolvency. Shortly thereafter, FTX’s CEO resigned and FTX and several affiliates of FTX filed for bankruptcy. The U.S. Department of Justice subsequently brought criminal charges, including charges of fraud, violations of federal securities laws, money laundering, and campaign finance offenses, against FTX’s former CEO and others. In November 2023, FTX’s former CEO was convicted of fraud and money laundering. Similar charges related to violations of anti-money laundering laws were brought in November 2023 against Binance and its former CEO.

In addition, several other entities in the digital asset industry filed for bankruptcy following FTX’s bankruptcy filing, such as BlockFi Inc. and Genesis Global Capital, LLC (“Genesis Capital”), a subsidiary of Genesis Global Holdco, LLC (“Genesis Holdco”). The SEC also brought charges against Genesis Capital and Gemini Trust Company, LLC (“Gemini”) in January 2023 for their alleged unregistered offer and sale of securities to retail investors. In October 2023, the New York Attorney General (“NYAG”) brought charges against Gemini, Genesis Capital, Genesis Asia Pacific PTE. LTD. (“Genesis Asia Pacific”), Genesis Holdco (together with Genesis Capital and Genesis Asia Pacific, the “Genesis Entities”), Genesis Capital’s former CEO, DCG, and DCG’s CEO alleging violations of the New York Penal Law, the New York General Business Law and the New York Executive Law. In February 2024, the NYAG amended its complaint to expand the charges against Gemini, the Genesis Entities, Genesis Capital’s former CEO, DCG, and DCG’s CEO to include harm to additional investors. Also in February 2024, the Genesis Entities entered into a settlement agreement with the

NYAG to resolve the NYAG’s allegations against the Genesis Entities, which settlement was subsequently approved by the Bankruptcy Court of the Southern District of New York.

On January 17, 2025, DCG agreed to entry of a cease-and-desist order and payment of a $38 million civil money penalty arising out of the SEC’s allegations that (i) DCG negligently engaged in conduct that misled investors about the impact of the default on Genesis Capital’s financial condition and (ii) DCG’s failure to exercise reasonable care in connection with certain statements concerning Genesis Capital’s financial condition created a materially false impression to the public regarding Genesis Capital’s financial health.

Furthermore, Genesis Holdco, together with certain of its subsidiaries, filed a voluntary petition for reorganization under Chapter 11 of the U.S. Bankruptcy Code in January 2023. While Genesis Holdco is not a service provider to the Trust, it is a wholly owned subsidiary of DCG, and is an affiliate of the Trust and the Sponsor.

These events have led to significant negative publicity around digital asset market participants including DCG, Genesis and DCG’s other affiliated entities. This publicity could negatively impact the reputation of the Sponsor and have an adverse effect on the trading price and/or the value of the Shares. Moreover, sales of a significant number of Shares of the Trust as a result of these events could have a negative impact on the trading price of the Shares.

These events have also led to a substantial increase in regulatory and enforcement scrutiny of the industry as a whole and of Digital Asset Trading Platforms in particular, including from the Department of Justice, the SEC, the CFTC, the White House and Congress. For example, in June 2023, the SEC brought charges against Binance (the “Binance Complaint”) and Coinbase (the “Coinbase Complaint”), alleging that they solicited U.S. investors to buy, sell, and trade “crypto asset securities” through their unregistered trading platforms and operated unregistered securities exchanges, brokerages and clearing agencies. Binance subsequently announced that it would be suspending USD deposits and withdrawals on Binance.US and that it plans to delist its USD trading pairs. In addition, in November 2023, the SEC brought similar charges against Kraken (the “Kraken Complaint”), alleging that it operated as an unregistered securities exchange, brokerage and clearing agency. The Binance Complaint, the Coinbase Complaint and the Kraken Complaint have led, and may in the future lead, to further volatility in digital asset prices. Between February 2025 and May 2025, the SEC entered into court-approved joint stipulations to dismiss each of the Binance Complaint, Coinbase Complaint and the Kraken Complaint. The SEC has terminated its investigation or enforcement action into many other digital asset market participants, as well.

In January 2025, the SEC launched a crypto task force dedicated to developing a comprehensive and clear regulatory framework for digital assets led by Commissioner Hester Peirce. Subsequently, Commissioner Peirce announced a list of specific priorities to further that initiative, which included pursuing final rules related to a digital asset’s security status, a revised path to registered offerings and listings for digital asset-based investment vehicles, and clarity regarding digital asset custody, lending and staking. Digital asset markets have also been negatively impacted by the failure of entities perceived to be integral to the digital asset ecosystem. For example, in March 2023, state banking regulators placed Silicon Valley Bank and Signature Bank into Federal Deposit Insurance Corporation (“FDIC”) receiverships. Also, in March 2023, Silvergate Bank announced plans to wind down and liquidate its operations. Because these banks were perceived to be the banks most open to providing services for the digital asset ecosystem in the United States, their failures may impact the willingness of banks (based on regulatory pressure or otherwise) to provide banking services to digital asset market participants. In addition, because these banks were perceived to be the banks most open to providing services for the digital asset ecosystem, their failure has caused a number of companies that provide digital asset-related services to be unable to find banks that are willing to provide them with such banking services. The inability to access banking services could negatively impact digital asset market participants and therefore the value of digital assets, including SUI, and thus the Shares. In addition, although these events did not have an impact directly on the Trust or the Sponsor when these bank failures occurred, it is possible that a future closing of a bank with which the Trust or the Sponsor has a financial relationship could subject the Trust or the Sponsor to adverse conditions and pose challenges in finding an alternative suitable bank to provide the Trust or the Sponsor with bank accounts and banking services.

Events such as these that impact the wider digital asset ecosystem are continuing to develop and change at a rapid pace and it is not possible to predict at this time all of the risks that they may pose to the Sponsor, the Trust, their affiliates and/or the Trust’s third-party service providers, or on the digital asset industry as a whole.

Continued disruption and instability in the digital asset markets as these events develop, including declines in the trading prices and liquidity of SUI, or the failure of service providers to the Trust, could have a material adverse effect on the value of the Shares and the Shares could lose all or substantially all of their value.

The value of the Shares relates directly to the value of SUI, the value of which may be highly volatile and subject to fluctuations due to a number of factors.

The value of the Shares relates directly to the value of the SUI held by the Trust and fluctuations in the price of SUI could adversely affect the value of the Shares. The market price of SUI may be highly volatile, and subject to a number of factors, including:

•

an increase in the global SUI supply that is publicly available for trading;

•

manipulative trading activity on Digital Asset Trading Platforms, which, in many cases, are largely unregulated;

•

the adoption of SUI as a medium of exchange, store-of-value or other consumptive asset and the maintenance and development of the open-source software protocol of the Sui Network;

•

forks in the Sui Network;

•

investors’ expectations with respect to interest rates, the rates of inflation of fiat currencies or SUI, and Digital Asset Trading Platform rates;

•

consumer preferences and perceptions of SUI specifically and digital assets generally;

•

fiat currency withdrawal and deposit policies on Digital Asset Trading Platforms;

•

the liquidity of Digital Asset Markets and any increase or decrease in trading volume on Digital Asset Markets;

•

investment and trading activities of large investors that invest directly or indirectly in SUI, including trading activity related to so-called digital asset treasury companies or similar vehicles that are intended to provide investors with indirect exposure to SUI;

•

a “short squeeze” resulting from speculation on the price of SUI, if aggregate short exposure exceeds the number of Shares available for purchase;

•

an active derivatives market for SUI or for digital assets generally;

•

a determination that SUI is a security or changes in SUI’s status under the federal securities laws;

•

monetary policies of governments, trade restrictions, currency devaluations and revaluations and regulatory measures or enforcement actions, if any, that restrict the use of SUI as a form of payment or the purchase of SUI on the Digital Asset Markets;

•

global or regional political, economic or financial conditions, events and situations, such as the novel coronavirus outbreak;

•

fees associated with processing a SUI transaction and the speed at which SUI transactions are settled on the Sui Network;

•

interruptions in service from or closures or failures of major Digital Asset Trading Platforms;

•

decreased confidence in Digital Asset Trading Platforms due to the largely unregulated nature and lack of transparency surrounding the operations of Digital Asset Trading Platforms;

•

increased competition from other forms of digital assets or payment services; and

•

the Trust’s own acquisitions or dispositions of SUI, since there is no limit on the amount of SUI that the Trust may acquire.

In addition, there is no assurance that SUI will maintain its value in the long or intermediate term. In the event that the price of SUI declines, the Sponsor expects the value of the Shares to decline proportionately.

The value of SUI as represented by the Index Price or by the Trust’s principal market may also be subject to momentum pricing due to speculation regarding future appreciation in value, leading to greater volatility that could adversely affect the value of the Shares. Momentum pricing typically is associated with growth stocks and other assets whose valuation, as determined by the investing public, accounts for future appreciation in value, if any. The Sponsor believes that momentum pricing of SUI has resulted, and may continue to result, in speculation regarding future appreciation in the value of SUI, inflating and making the Index Price more volatile. As a result, SUI may be more likely to fluctuate in value due to changing investor confidence, which could impact future appreciation or depreciation in the Index Price and could adversely affect the value of the Shares.

Due to the largely unregulated nature and lack of transparency surrounding the operations of Digital Asset Trading Platforms, they may experience fraud, market manipulation, business failures, security failures or operational problems, which may adversely affect the value of SUI and, consequently, the value of the Shares.

Digital Asset Trading Platforms are relatively new and, in many ways, are not subject to, or may not comply with, regulation in relevant jurisdictions in a manner similar to other regulated trading platforms, such as national securities exchanges or designated contract markets. While many prominent Digital Asset Trading Platforms provide the public with significant information regarding their on-chain activities, ownership structure, management teams, corporate practices, cybersecurity practices and regulatory compliance, many other Digital Asset Trading Platforms do not provide this information. Furthermore, while Digital Asset Trading Platforms are and may continue to be subject to federal and state licensing requirements in the United States, Digital Asset Trading Platforms do not currently appear to be subject to regulation in a similar manner as other regulated trading platforms, such as national securities exchanges or designated contract markets. As a result, the marketplace may lose confidence in Digital Asset Trading Platforms, including prominent trading platforms that handle a significant volume of SUI trading.

Many Digital Asset Trading Platforms, both in the United States and abroad, are unlicensed, not subject to, or not in compliance with, regulation in relevant jurisdictions, or operate without extensive supervision by governmental authorities. In particular, those located outside the United States may be subject to significantly less stringent regulatory and compliance requirements in their local jurisdictions and may take the position that they are not subject to laws and regulations that would apply to a national securities exchange or designated contract market in the United States, or may, as a practical matter, be beyond the ambit of U.S. regulators. As a result, trading activity on or reported by these Digital Asset Trading Platforms is generally significantly less regulated than trading activity on or reported by regulated U.S. securities and commodities markets, and may reflect behavior that would be prohibited in regulated U.S. trading venues. For example, in 2022 one report claimed that trading volumes on Digital Asset Trading Platforms were inflated by over 70% due to false or non-economic trades, with specific focus on unlicensed trading platforms located outside of the United States. Such reports may indicate that the Digital Asset Trading Platform Market is significantly smaller than expected and that the U.S. makes up a significantly larger percentage of the Digital Asset Trading Platform Market than is commonly understood, or that a much larger portion of digital asset market activity takes place on decentralized finance platforms than is commonly understood. Nonetheless, any actual or perceived false trading in the Digital Asset Trading Platform Market, and any other fraudulent or manipulative acts and practices, could adversely affect the value of SUI and/or negatively affect the market perception of SUI, which could in turn adversely impact the value of the Shares.

The SEC has also identified possible sources of fraud and manipulation in the Digital Asset Markets generally, including, among others (1) “wash-trading”; (2) persons with a dominant position in a digital asset manipulating pricing in such digital asset; (3) hacking of the underlying digital asset network and trading platforms; (4) malicious control of the underlying digital asset network; (5) trading based on material, non-public information (for example, plans of market participants to significantly increase or decrease their holdings in a digital asset, new sources of demand for a digital asset) or based on the dissemination of false and misleading information; (6) manipulative activity involving purported “stablecoins,” including Tether; and (7) fraud and manipulation at Digital Asset Markets. The use or presence of such acts and practices in the Digital Asset Markets could, for example, falsely inflate the volume of SUI present in the Digital Asset Markets or cause distortions in the price of SUI, among other things that could adversely affect the Trust or cause losses to shareholders. Moreover, tools to detect and deter fraudulent or manipulative trading activities, such as market manipulation, front-running of trades, and wash-trading, may not be available to or employed by Digital Asset Markets, or may not exist at all. Many Digital Asset Markets also lack certain safeguards put in place by exchanges for more traditional assets to enhance the stability of trading on the exchanges and prevent “flash crashes,” such as limit-down circuit breakers. As a result, the prices of SUI on Digital Asset Markets may be subject to larger and/or more frequent sudden declines than assets traded on more traditional exchanges.

In addition, over the past several years, some Digital Asset Trading Platforms have been closed, been subject to criminal and civil litigation and have entered into bankruptcy proceedings due to fraud and manipulative activity, business failure and/or security breaches. In many of these instances, the customers of such Digital Asset Trading Platforms were not compensated or made whole for the partial or complete losses of their account balances in such Digital Asset Trading Platforms. In some instances, customers are made whole only in dollar terms as of the Digital Asset Trading Platform’s date of failure, rather than on a digital asset basis, meaning customers may still lose out on any price increase in digital assets.

While smaller Digital Asset Trading Platforms are less likely to have the infrastructure and capitalization that make larger Digital Asset Trading Platforms more stable, larger Digital Asset Trading Platforms are more likely to be appealing targets for hackers and malware. For example, in February 2025, hackers reportedly compromised a transaction from Bybit’s multisignature cold wallets, enabling the hackers to steal over $1.5 billion of Ether from Bybit. Shortcomings or ultimate failures of larger Digital Asset Trading Platforms are more likely to have contagion effects on the digital asset ecosystem, including on the price of SUI, and therefore may also be more likely to be targets of regulatory enforcement action. For example, in November 2022, FTX, another of the world’s largest Digital Asset Trading Platforms, filed for bankruptcy protection and subsequently halted customer withdrawals as well as trading on its FTX.US platform. Fraud, security failures and operational problems all played a role in FTX’s issues and downfall. Moreover, Digital Asset Trading Platforms have been a subject of enhanced regulatory and enforcement scrutiny, and Digital Asset Markets have experienced continued instability, following the failure of FTX. In particular, in June 2023, the SEC brought the Binance Complaint and Coinbase Complaint, alleging that Binance and Coinbase operated unregistered securities exchanges, brokerages and clearing agencies. In addition, in November 2023, the SEC brought the Kraken Complaint, alleging that Kraken operated as an unregistered securities exchange, brokerage and clearing agency. Between February 2025 and May 2025, the SEC entered into court-approved joint stipulations to dismiss each of the Binance Complaint, Coinbase Complaint and the Kraken Complaint. The SEC has terminated its investigation or enforcement action into many other digital asset market participants as well.

Negative perception, a lack of stability and standardized regulation in the Digital Asset Markets and/or the closure or temporary shutdown of Digital Asset Trading Platforms due to fraud, business failure, security breaches or government mandated regulation, and associated losses by customers, may reduce confidence in the Sui Network and result in greater volatility in the prices of SUI. Furthermore, the closure or temporary shutdown of a Digital Asset Trading Platform used in calculating the Index Price may result in a loss of confidence in the Trust’s ability to determine its NAV on a daily basis. These potential consequences of such a Digital Asset Trading Platform’s failure could adversely affect the value of the Shares.

Digital Asset Trading Platforms may be exposed to front-running.

Digital Asset Trading Platforms may be susceptible to “front-running,” which refers to the process when someone uses technology or market advantage to get prior knowledge of upcoming transactions. Front-running is a frequent activity on centralized as well as decentralized trading platforms. By using bots functioning on a millisecond-scale timeframe, bad actors are able to take advantage of the forthcoming price movement and make economic gains at the cost of those who had introduced these transactions. The objective of a front runner is to buy tokens at a low price and later sell them at a higher price while simultaneously exiting the position. To the extent that front-running occurs, it may result in investor frustrations and concerns as to the price integrity of Digital Asset Trading Platforms and digital assets more generally.

Digital Asset Trading Platforms may be exposed to wash-trading.

Digital Asset Trading Platforms may be susceptible to wash-trading. Wash-trading occurs when offsetting trades are entered into for other than bona fide reasons, such as the desire to inflate reported trading volumes. Wash-trading may be motivated by non-economic reasons, such as a desire for increased visibility on popular websites that monitor markets for digital assets so as to improve a trading platform’s attractiveness to investors who look for maximum liquidity, or it may be motivated by the ability to attract listing fees from token issuers who seek the most liquid and high-volume trading platforms on which to list their tokens. Results of wash-trading may include unexpected obstacles to trade and erroneous investment decisions based on false information.

Even in the United States, there have been allegations of wash-trading even on regulated venues. Any actual or perceived false trading on Digital Asset Trading Platforms, and any other fraudulent or manipulative acts and practices, could adversely affect the value of SUI and/or negatively affect the market perception of SUI.

To the extent that wash-trading either occurs or appears to occur in Digital Asset Trading Platforms, investors may develop negative perceptions about SUI and the digital assets industry more broadly, which could adversely impact the price of SUI and, therefore, the price of the Shares. Wash-trading also may place more legitimate Digital Asset Trading Platforms at a relative competitive disadvantage.

The Index has a limited history and a failure of the Index Price could adversely affect the value of the Shares.

The Index has a limited history and the Index Price is a composite reference rate calculated using trading price data from various Digital Asset Trading Platforms chosen by the Index Provider. The Digital Asset Trading Platforms chosen by the Index Provider have also changed over time. The Index Provider may remove or add Digital Asset Trading Platforms to the Index in the future at its discretion. For more information on the inclusion criteria for Digital Asset Trading Platforms in the Index, see “Item 1. Business—Overview of the Sui Industry and Market—SUI Value—The Index and the Index Price.”

Although the Index is designed to accurately capture the market price of SUI, third parties may be able to purchase and sell SUI on public or private markets not included among the Constituent Trading Platforms of the Index, and such transactions may take place at prices materially higher or lower than the Index Price. Moreover, there may be variances in the prices of SUI on the various Digital Asset Trading Platforms, including as a result of differences in fee structures or administrative procedures on different Digital Asset Trading Platforms. For example, based on data provided by the Index Provider, on any given day during the year ended December 31, 2025, the maximum differential between the 4:00 p.m., New York time spot price of any single Digital Asset Trading Platform included in the Index and the Index Price was 2.49% and the average of the maximum differentials of the 4:00 p.m., New York time, spot price of each Digital Asset Trading Platform included in the Index and the Index Price was 0.98%. During this same period, the average differential between the 4:00 p.m., New York time, spot prices of all the Digital Asset Trading Platforms included in the Index and the Index Price was 0.01%. All Digital Asset Trading Platforms that were included in the Index throughout the period were considered in this analysis. To the extent such prices differ materially from the Index Price, investors may lose confidence in the Shares’ ability to track the market price of SUI, which could adversely affect the value of the Shares.

The Index Price used to calculate the value of the Trust’s SUI may be volatile, and purchasing and selling activity in the Digital Asset Markets associated with Basket creations and redemptions may affect the Index Price and Share trading prices, adversely affecting the value of the Shares.

The price of SUI on public Digital Asset Trading Platforms has a very limited history, and during this history, SUI prices on the Digital Asset Markets more generally, and on Digital Asset Trading Platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the Index is designed to limit exposure to the interruption of individual Digital Asset Trading Platforms, the Index Price, and the price of SUI generally, remains subject to volatility experienced by Digital Asset Trading Platforms, and such volatility could adversely affect the value of the Shares. For example, since the commencement of the Trust’s operations, the Index Price ranged from $0.53 to $5.23, with the straight average being $2.79 through December 31, 2025. In addition, during the year ended December 31, 2025, the Index Price ranged from $1.33 to $5.23. The Sponsor has not observed a material difference between the Index Price and average prices from the Constituent Trading Platforms individually or as a group. The price of SUI more generally has experienced volatility similar to the Index Price during these periods. For additional information on

movement of the Index Price and the price of SUI, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Historical NAV and SUI Prices.”

Furthermore, because the number of Digital Asset Trading Platforms is limited, the Index will necessarily be comprised of a limited number of Digital Asset Trading Platforms. If a Digital Asset Trading Platform were subjected to regulatory, volatility or other pricing issues, the Index Provider would have limited ability to remove such Digital Asset Trading Platform from the Index, which could skew the price of SUI as represented by the Index. Trading on a limited number of Digital Asset Trading Platforms may result in less favorable prices and decreased liquidity of SUI and, therefore, could have an adverse effect on the value of the Shares.

Purchasing activity associated with acquiring SUI required for the creation of Baskets may increase the market price of SUI on the Digital Asset Markets, which will result in higher prices for the Shares. Alternatively, selling activity associated with sales of SUI withdrawn from the Trust in connection with the redemption of Baskets may decrease the market price of SUI on the Digital Asset Markets, which will result in lower prices for the Shares. Increases or decreases in the market price of SUI may also occur as a result of the purchasing or selling activity of other market participants. Other market participants may attempt to benefit from an increase or decrease in the market price of SUI that may result from increased purchasing or selling activity of SUI connected with the creation or redemption of Baskets. Consequently, the market price of SUI may decline immediately after Baskets are created. Decreases in the market price of SUI may also occur as a result of sales in Secondary Markets by other market participants. If the Index Price declines, the value of the Shares will generally also decline.

Competition from the emergence or growth of other digital assets could have a negative impact on the price of SUI and adversely affect the value of the Shares.

As of December 31, 2025, SUI was the twenty-third largest digital asset by market capitalization, as tracked by CoinMarketCap.com. As of December 31, 2025, the alternative digital assets tracked by CoinMarketCap.com had a total market capitalization of approximately $2,678.0 billion (including the approximately $5.2 billion market cap of SUI), as calculated using market prices and total available supply of each digital asset, excluding stablecoins and tokens pegged to other assets. In addition, SUI faces competition from a wide range of digital assets, including Bitcoin and Ether. Many consortiums and financial institutions are also researching and investing resources into private or permissioned blockchain platforms rather than open platforms like the Sui Network. In addition, SUI is supported by fewer trading platforms than more established digital assets, such as Bitcoin and Ether, which could impact its liquidity. In addition, the Sui Network is in direct competition with other smart contract platforms, such as the Ethereum, Polkadot, Avalanche and Cardano networks. Competition from the emergence or growth of alternative digital assets or other smart contract platforms could have a negative impact on the demand for, and price of, SUI, and thereby adversely affect the value of the Shares. Moreover, the growth of tokenized assets and other on-chain financial products that offer yield, stability, or regulatory clarity may also divert capital and user engagement away from the Sui Network, which could negatively impact SUI’s market demand and the value of the Shares.

Investors may also invest in SUI through means other than the Shares, including through direct investments in SUI and other financial vehicles, including securities backed by or linked to SUI and digital asset financial vehicles similar to the Trust.

The Trust and the Sponsor face competition with respect to the creation of competing exchange-traded spot SUI products, among other digital asset vehicles. Whether the Trust is successful in maintaining its scale and achieving its intended competitive position may be impacted by a range of factors, including its fee structure relative to those competing products. The Trust’s competitors may also charge a substantially lower fee than the Sponsor’s Fee in an effort to achieve initial market acceptance and scale, which could cause investors to favor such competing products over the Trust.

If the Trust fails to continue to maintain or grow sufficient scale due to competition, the Sponsor may have difficulty raising sufficient revenue to cover the costs associated with maintaining the Trust and such shortfalls could impact the Sponsor’s ability to properly invest in robust ongoing operations and controls of the Trust to minimize the risk of operating events, errors, or other forms of losses to the shareholders. Furthermore, the Trust may fail to continue to attract adequate liquidity in the secondary market due to such competition, resulting in a small number of Authorized Participants willing to make a market in the Shares, which in turn could result in the Shares trading at a significant premium or discount for extended periods. Likewise, market and financial conditions, among other conditions outside the Trust’s control, may cause investors to find it more attractive to gain exposure to SUI through other vehicles, rather than the Trust.

In addition, to the extent digital asset financial vehicles other than the Trust tracking the price of SUI come to represent a significant proportion of the demand for SUI, large purchases or redemptions of the securities of these digital asset financial vehicles, or private funds holding SUI, could negatively affect the Index Price, the NAV, the NAV per Share, the value of the Shares, the Principal Market NAV and the Principal Market NAV per Share. Accordingly, there can be no assurance that the Trust will be able to maintain its scale and achieve its intended competitive positioning relative to competitors, which could adversely affect the performance of the Trust and the value of the Shares.

Congestion or delay on the Sui Network may delay purchases or sales of SUI by the Trust.

Increased transaction volume could result in delays in the recording of transactions due to network congestion. Moreover, unforeseen system failures, disruptions in operations, or poor connectivity may also result in delays in the recording of transactions on the Sui Network. The Sui Network has experienced multiple such disruptions since launch. For example, in November 2024, the Sui Network experienced a temporary outage after a software issue caused certain validators to crash, halting transaction processing until the issue was resolved. In addition, in January 2026, the Sui Network experienced a consensus-related disruption that stalled transaction processing and affected validator operations and dApp connectivity.

Any such delays could affect an Authorized Participant’s ability to buy or sell SUI at an advantageous price resulting in decreased confidence in the Sui Network. Over the longer term, delays in confirming transactions could reduce the attractiveness to merchants and other commercial parties as a means of payment. As a result, the Sui Network and the value of the Trust would be adversely affected.

The SEC has approved generic listing standards for commodity-based trust shares and may approve other applications under Rule 19b-4 of the Exchange Act to list competing digital assets as exchange-traded products, which could reduce demand for, and the price of, SUI and adversely impact the value of the Shares.

To date, the SEC has approved applications under Rule 19b-4 of the Exchange Act to list spot digital asset exchange-traded products which hold Bitcoin and Ether, as well as generic listing standards for commodity-based trust shares holding digital assets. To the extent competing digital assets exchange-traded products, other than those which hold SUI, come to represent a significant proportion of the demand for digital assets generally, demand for, and the price of, SUI could be reduced. Such reduced demand could in turn negatively affect the Index Price, the NAV, the NAV per Share, the value of the Shares, the Principal Market NAV and the Principal Market NAV per Share. Accordingly, there can be no assurance that the Trust will be able to maintain its scale and achieve its intended competitive positioning relative to competitors, which could adversely affect the performance of the Trust and the value of the Shares.

Competition from central bank digital currencies (“CBDCs”) and emerging payments initiatives involving financial institutions could adversely affect the price of SUI and other digital assets.

Central banks in various countries have introduced digital forms of legal tender (“CBDCs”). China’s CBDC project, known as Digital Currency Electronic Payment, has reportedly been tested in a live pilot program conducted in multiple cities in China. Central banks representing at least 130 countries have published retail or wholesale CBDC work ranging from research to pilot projects. Whether or not they incorporate blockchain or similar technology, CBDCs, as legal tender in the issuing jurisdiction, could have an advantage in competing with, or replace, SUI and other cryptocurrencies as a medium of exchange or store of value. Central banks and other governmental entities have also announced cooperative initiatives and consortia with private sector entities, with the goal of leveraging blockchain and other technology to reduce friction in cross-border and interbank payments and settlement, and commercial banks and other financial institutions have also recently announced a number of initiatives of their own to incorporate new technologies, including blockchain and similar technologies, into their payments and settlement activities, which could compete with, or reduce the demand for, SUI. As a result of any of the foregoing factors, the price of SUI could decrease, which could adversely affect an investment in the Trust.

Prices of SUI may be affected due to stablecoins (including Tether and USDC), the activities of stablecoin issuers and their regulatory treatment.

While the Trust does not invest in stablecoins, it may nonetheless be exposed to these and other risks that stablecoins pose for the market for SUI and other digital assets. Stablecoins are digital assets designed to have a stable value over time as compared to typically volatile digital assets, and are typically marketed as being pegged to the value of a referenced asset, normally a fiat currency, such as the U.S. dollar. Although the prices of stablecoins are intended to be stable compared to their referenced asset, in many cases their prices fluctuate, sometimes significantly. This volatility has in the past impacted the prices of certain digital assets, and has at times caused certain stablecoins to lose their “peg” to the underlying fiat currency. Stablecoins are a relatively new phenomenon, and it is impossible to know all of the risks that they could pose to participants in the digital asset markets. In addition, some have argued that some stablecoins, particularly Tether, are improperly issued without sufficient backing in a way that could cause artificial rather than genuine demand for digital assets, raising their prices. Regulators have also charged stablecoin issuers with violations of law or otherwise required certain stablecoin issuers to cease certain operations. For example, on February 17, 2021, the New York Attorney General entered into an agreement with Tether’s operators, requiring them to cease any further trading activity with New York persons and pay $18.5 million in penalties for false and misleading statements made regarding the assets backing Tether. On October 15, 2021, the CFTC announced a settlement with Tether’s operators in which they agreed to pay $42.5 million in fines to settle charges that, among others, Tether’s claims that it maintained sufficient U.S. dollar reserves to back every Tether stablecoin in circulation with the “equivalent amount of corresponding fiat currency” held by Tether were untrue.

USDC is a reserve-backed stablecoin issued by Circle Internet Financial that is commonly used as a method of payment in digital asset markets, including the SUI market. The issuer of USDC uses the Circle Reserve Fund to hold cash, U.S. Treasury bills, notes and other obligations issued or guaranteed as to principal and interest by the U.S. Department of the Treasury, and repurchase agreements secured by such obligations or cash, which serve as reserves backing USDC stablecoins. While USDC is designed to maintain a stable

value at 1 U.S. dollar at all times, on March 10, 2023, the value of USDC fell below $1.00 (and remained below for multiple days) after Circle Internet Financial disclosed that $3.3 billion of the USDC reserves were held at Silicon Valley Bank, which had entered FDIC receivership earlier that day. Popular stablecoins are reliant on the U.S. banking system and U.S. treasuries, and the failure of either to function normally could impede the function of stablecoins or lead to outsized redemption requests, and therefore could adversely affect the value of the Shares.

Given the role that stablecoins play in global digital asset markets, their fundamental liquidity can have a dramatic impact on the broader digital asset market, including the market for SUI. Because a large portion of the digital asset market still depends on stablecoins such as Tether and USDC, there is a risk that a disorderly de-pegging or a run on Tether or USDC could lead to dramatic market volatility in, and/or materially and adversely affect the prices of, digital assets more broadly.

Volatility in stablecoins, operational issues with stablecoins (for example, technical issues that prevent settlement), concerns about the sufficiency of any reserves that support stablecoins, or regulatory concerns about stablecoin issuers or intermediaries that support stablecoins, could impact individuals’ willingness to trade on trading venues that rely on stablecoins and could impact the price of SUI, and in turn, an investment in the Shares.

Risk Factors Related to the Trust and the Shares

The Trust relies on the Custodial Entities, the Authorized Participants and other third-party service providers to perform certain functions essential to managing the affairs of the Trust. In addition, Liquidity Providers are relied upon to facilitate the purchase and sale of SUI in connection with creations and redemptions of Shares in cash (“Cash Orders”), and the Transfer Agent and Grayscale Investments Sponsors, LLC (in such capacity, the “Liquidity Engager”), are relied upon to facilitate such Cash Orders. Any disruptions to a service provider’s business operations, resulting from business failures, financial instability, security failures, government mandated regulation or operational problems, could have an adverse impact on the Trust’s ability to access critical services and be disruptive to the operations of the Trust and require the Sponsor or the Liquidity Engager, as the case may be, to replace such service provider. Moreover, the Sponsor could decide to replace a service provider to the Trust, or the Liquidity Engager may decide to replace a Liquidity Provider, for other reasons.

If the Sponsor decides, or is required, to replace Coinbase Custody Trust Company, LLC as the custodian of the Trust’s SUI or Coinbase, Inc. as the prime broker controlling and securing the Trust’s Settlement Balance, transfer of the respective maintenance responsibilities of the Vault Balance or the Settlement Balance to another party or parties will likely be complex and could subject the Trust’s SUI to the risk of loss during the transfer, which could have a negative impact on the performance of the Shares or result in loss of the Trust’s assets.

Moreover, the legal rights of customers with respect to digital assets held on their behalf by a third-party custodian, such as the Custodial Entities, in insolvency proceedings are currently uncertain. The Prime Broker Agreement contains an agreement by the parties to treat the digital assets credited to the Trust’s Vault Balance and Settlement Balance as financial assets under Article 8 in addition to stating that the Custodian will serve as fiduciary and custodian on the Trust’s behalf with respect to the Trust’s SUI held in the Vault Balance, and that any SUI credited to the Settlement Balance will be treated as custodial assets.

The Custodial Entities’ parent, Coinbase Global, has also stated in its public securities filings that in light of the inclusion of provisions relating to Article 8 in its custody and prime broker client agreements, it believes that a court would not treat custodied digital assets as part of its general estate in the event the Custodial Entities were to experience insolvency. However, due to the novelty of digital asset custodial arrangements courts have not yet considered this type of treatment for custodied digital assets and it is not possible to predict with certainty how they would rule in such a scenario. Moreover, the Custodian and the Prime Broker are potentially subject to different insolvency regimes and there is no assurance that the digital assets credited to the Trust’s Settlement Balance would be treated similarly to those credited to the Trust’s Vault Balance in an insolvency, notwithstanding the rights and obligations conferred under the Prime Broker Agreement or Coinbase Global’s views regarding the treatment of such assets under Article 8. In the event that the Custodian or the Prime Broker and/or Coinbase Global became subject to insolvency proceedings and a court were to rule that the custodied digital assets were part of the Custodian’s, the Prime Broker’s and/or Coinbase Global’s general estate and not the property of the Trust, then the Trust would be treated as a general unsecured creditor in such insolvency proceedings and the Trust would be subject to the loss of all or a significant portion of its assets.

In addition, the Custodian is a fiduciary under § 100 of the New York Banking Law and a qualified custodian for purposes of Rule 206(4)-2(d)(6) under the Investment Advisers Act and is licensed to custody the Trust’s SUI in trust on the Trust’s behalf. However, the SEC previously released proposed amendments in February 2023 to Rule 206(4)-2 that, if enacted as proposed, would amend the definition of a “qualified custodian” under Rule 206(4)-2(d)(6). Executive officers of the Custodian’s parent company have made public statements indicating that the Custodian would remain a qualified custodian under the proposed SEC rule, if enacted as proposed. In June 2025, however, the SEC formally withdrew that proposed rulemaking and stated that it does not intend to issue final rules based

on the proposal. However, there can be no assurance that the Custodian would continue to qualify as a “qualified custodian” under a final rule that may be proposed or adopted by the SEC in the future.

To the extent that the Sponsor is not able to find a suitable party willing to serve as custodian, the Sponsor may be required to terminate the Trust and liquidate the Trust’s SUI. In addition, to the extent that the Sponsor finds a suitable party and must enter into a modified or separate custody agreement that is less favorable for the Trust or Sponsor and/or transfer the Trust’s assets in a relatively short time period, the safekeeping of the Trust’s SUI may be adversely affected, which may in turn adversely affect the value of the Shares. Likewise, if the Sponsor is required to replace any other service provider, they may not be able to find a party willing to serve in such capacity in a timely manner or at all. If the Sponsor decides, or is required, to replace an Authorized Participant and/or if the Liquidity Engager decides, or is required, to replace a Liquidity Provider, this could negatively impact the Trust’s ability to create new Shares, which would impact the Shares’ liquidity and could have a negative impact on the value of the Shares.

In the event that one or more Authorized Participants having substantial interests in Shares or otherwise responsible for a significant portion of the Shares’ daily trading volume on NYSE Arca terminates its Participant Agreement, the liquidity of the Shares would likely decrease, which could adversely affect the value of the Shares. In addition, if the Liquidity Engager is unable to engage one or more Liquidity Providers to obtain or receive SUI in connection with Cash Orders, the Trust may have difficulty maintaining the participation of certain Authorized Participants or engaging additional Authorized Participants. Under such circumstances, the liquidity of the Shares would likely decrease, which could adversely affect the value of the Shares.

The Shares may trade at a price that is at, above or below the Trust’s NAV per Share as a result of the non-concurrent trading hours between NYSE Arca and the Digital Asset Trading Platform Market.

The Trust’s NAV per Share will fluctuate with changes in the market value of SUI, and the Sponsor expects the trading price of the Shares to fluctuate in accordance with changes in the Trust’s NAV per Share, as well as market supply and demand. However, the Shares may trade on NYSE Arca at a price that is at, above or below the Trust’s NAV per Share for a variety of reasons. For example, NYSE Arca is open for trading in the Shares for a limited period each day, but the Digital Asset Trading Platform Market is a 24-hour marketplace. During periods when NYSE Arca is closed but Digital Asset Trading Platforms are open, significant changes in the price of SUI on the Digital Asset Trading Platform Market could result in a difference in performance between the value of SUI as measured by the Index and the most recent NAV per Share or closing trading price. For example, if the price of SUI on the Digital Asset Trading Platform Market, and the value of SUI as measured by the Index, move significantly in a negative direction after the close of NYSE Arca, the trading price of the Shares may “gap” down to the full extent of such negative price shift when NYSE Arca reopens. If the price of SUI on the Digital Asset Trading Platform Market drops significantly during hours NYSE Arca is closed, shareholders may not be able to sell their Shares until after the “gap” down has been fully realized, resulting in an inability to mitigate losses in a negative market. Even during periods when NYSE Arca is open, large Digital Asset Trading Platforms (or a substantial number of smaller Digital Asset Trading Platforms) may be lightly traded or closed for any number of reasons, which could increase trading spreads and widen any premium or discount on the Shares.

Any suspension or other unavailability of the Trust’s redemption program may cause the Shares to trade at a discount to the NAV per Share.

Prior to their uplisting to NYSE Arca, the Shares traded on OTCQB at both premiums and discounts to the NAV per Share, which at times were substantial. The Sponsor believes that the trading price of the Shares has diverged from the NAV per Share in the past due, in part, to the holding period under Rule 144 for Shares purchased in the private placement and the lack of an ongoing redemption program, as a result of which Authorized Participants had been unable to take advantage of arbitrage opportunities when the market value of the Shares deviated from the NAV per Share. Although the Sponsor has observed that the commencement of the Trust’s redemption program, in conjunction with the listing of the Shares on NYSE Arca, has had the effect of reducing the discount at which the Shares had been trading on the OTCQB immediately prior to the commencement of the redemption program, there can be no assurance that the Trust’s redemption program will not be suspended or become unavailable again in the future. In addition, if the Sponsor decides to limit Cash Orders at a time when the Shares are trading at a premium or a discount to the NAV per Share, and In-Kind Orders are not broadly available or are not being utilized by a sufficient number of Authorized Participants, the arbitrage mechanism may fail to effectively function, which could impact the Shares’ liquidity and/or cause the Shares to trade at premiums and discounts to the NAV per Share, and otherwise have a negative impact on the value of the Shares.

Shareholders may suffer a loss on their investment if the Shares trade above or below the Trust’s NAV per Share.

Historically, the Shares have traded at both a premium and discount to the NAV per Share, which at times have been substantial. If the Shares trade on NYSE Arca in the future at a premium, investors who purchase Shares on NYSE Arca will pay more for their Shares than investors who purchase Shares directly from Authorized Participants. In contrast, if the Shares trade on NYSE Arca in the future at a discount, investors who purchase Shares directly from Authorized Participants will pay more for their Shares than investors

who purchase Shares on NYSE Arca. The premium at which the Shares have traded has fluctuated over time. From November 24, 2025 to December 31, 2025, the maximum premium of the closing price of the Shares quoted on OTCQB over the value of the Trust’s NAV per Share was 38%, the average premium was 29%, the maximum discount of the closing price of the Shares quoted on OTCQB below the value of the Trust’s NAV per Share was 30%, and the average discount was 11%. The closing price of the Shares, as quoted on OTCQB at 4:00 p.m., New York time, on each business day between November 24, 2025 and December 31, 2025, has been quoted at a discount on 20 days. As of December 31, 2025, the Trust’s Shares were quoted on OTCQB at a discount of 3% to the Trust’s NAV per Share. As of March 19, 2026, the Trust's Shares were quoted on NYSE Arca at a premium of 0.0007% to the Trust's NAV per Share. As a result, shareholders who purchase Shares on NYSE Arca at a premium may suffer a loss on their investment if they sell their Shares at a time when the premium has decreased from the premium at which they purchased the Shares even if the NAV per Share remains the same. Likewise, shareholders that purchase Shares directly from the Trust may suffer a loss on their investment if they sell their Shares at a time when the Shares are trading at a discount on NYSE Arca. Furthermore, shareholders may suffer a loss on their investment even if the NAV per Share increases because the decrease in any premium or increase in any discount may offset any increase in the NAV per Share.

The amount of the Trust’s assets represented by each Share will decline over time as the Trust pays the Sponsor’s Fee and Additional Trust Expenses, and as a result, the value of the Shares may decrease over time.

The Sponsor’s Fee accrues daily in U.S. dollars at an annual rate based on the NAV Fee Basis Amount, which is based on the NAV of the Trust, and is paid to the Sponsor in SUI. See “Item 1. Business—Valuation of SUI and Determination of NAV—Disposition of SUI.” As a result, the amount of Trust’s assets represented by each Share declines as the Trust pays the Sponsor’s Fee (or sells SUI in order to raise cash to pay any Additional Trust Expenses), which may cause the Shares to decrease in value over time or dampen any increase in value.

The value of the Shares may be influenced by a variety of factors unrelated to the value of SUI.

The value of the Shares may be influenced by a variety of factors unrelated to the price of SUI and the Digital Asset Trading Platforms included in the Index that may have an adverse effect on the value of the Shares. These factors include the following factors:

•

Unanticipated problems or issues with respect to the mechanics of the Trust’s operations and the trading of the Shares may arise, in particular due to the fact that the mechanisms and procedures governing the creation and offering of the Shares and storage of SUI have been developed specifically for this product;

•

The Trust could experience difficulties in operating and maintaining its technical infrastructure, including in connection with expansions or updates to such infrastructure, which are likely to be complex and could lead to unanticipated delays, unforeseen expenses and security vulnerabilities;

•

The Trust could experience unforeseen issues relating to the performance and effectiveness of the security procedures used to protect the Vault Balance, or the security procedures may not protect against all errors, software flaws or other vulnerabilities in the Trust’s technical infrastructure, which could result in theft, loss or damage of its assets; or

•

Although the Sui Network does not have any privacy enhancing features at this time, if any such features are introduced to the Sui Network in the future, service providers may decide to terminate their relationships with the Trust due to concerns that the introduction of privacy enhancing features to the Sui Network may increase the potential for SUI to be used to facilitate crime, exposing such service providers to potential reputational harm.

Any of these factors could affect the value of the Shares, either directly or indirectly through their effect on the Trust’s assets.

Shareholders do not have the protections associated with ownership of shares in an investment company registered under the Investment Company Act or the protections afforded by the CEA.

The Investment Company Act is designed to protect investors by preventing insiders from managing investment companies to their benefit and to the detriment of public investors, such as: the issuance of securities having inequitable or discriminatory provisions; the management of investment companies by irresponsible persons; the use of unsound or misleading methods of computing earnings and asset value; changes in the character of investment companies without the consent of investors; and investment companies from engaging in excessive leveraging. To accomplish these ends, the Investment Company Act requires the safekeeping and proper valuation of fund assets, restricts greatly transactions with affiliates, limits leveraging, and imposes governance requirements as a check on fund management.

The Trust is not a registered investment company under the Investment Company Act, and the Sponsor believes that the Trust is not required to register under such act. Consequently, shareholders do not have the regulatory protections provided to investors in investment companies.

The Trust will not hold or trade in commodity interests regulated by the CEA, as administered by the CFTC. Furthermore, the Sponsor believes that the Trust is not a commodity pool for purposes of the CEA, and that neither the Sponsor nor the Trustee is subject

to regulation by the CFTC as a commodity pool operator or a commodity trading adviser in connection with the operation of the Trust. Consequently, shareholders will not have the regulatory protections provided to investors in CEA-regulated instruments or commodity pools.

There is no guarantee that an active trading market for the Shares will continue to develop.

The Shares are trading on NYSE Arca, and an active trading market for the Shares has developed. However, there can be no assurance that such trading market will be maintained or continue to develop on NYSE Arca. In addition, NYSE Arca can halt the trading of the Shares for a variety of reasons. To the extent that NYSE Arca halts trading in the Shares, whether on a temporary or permanent basis, investors may not be able to buy or sell Shares, which could adversely affect the value of the Shares. If an active trading market for the Shares does not continue to exist, the market prices and liquidity of the Shares may be adversely affected.

As the Sponsor and its management have limited history of operating investment vehicles like the Trust, their experience may be inadequate or unsuitable to manage the Trust.

The past performances of the Sponsor’s management in other investment vehicles, including their experiences in the digital asset and venture capital industries, are no indication of their ability to manage an investment vehicle such as the Trust. If the experience of the Sponsor and its management is inadequate or unsuitable to manage an investment vehicle such as the Trust, the operations of the Trust may be adversely affected.

Furthermore, the Sponsor is currently engaged in the management of other investment vehicles which could divert their attention and resources. If the Sponsor were to experience difficulties in the management of such other investment vehicles that damaged the Sponsor or its reputation, it could have an adverse impact on the Sponsor’s ability to continue to serve as Sponsor for the Trust.

Security threats to the Trust’s Vault Balance or Settlement Balance could result in the halting of Trust operations, including the creation and redemption of Baskets, and a loss of Trust assets or damage to the reputation of the Trust, each of which could result in a reduction in the value of the Shares.

Security breaches, computer malware and computer hacking attacks have been a prevalent concern in relation to digital assets. The Sponsor believes that the Trust’s SUI held in the Vault Balance, as well as the Trust’s SUI held temporarily in the Settlement Balance, will be an appealing target to hackers or malware distributors seeking to destroy, damage or steal the Trust’s SUI and will only become more appealing as the Trust’s assets grow. To the extent that the Trust, the Sponsor or the Custodial Entities are unable to identify and mitigate or stop new security threats or otherwise adapt to technological changes in the digital asset industry, the Trust’s SUI may be subject to theft, loss, destruction or other attack.

The Sponsor believes that the security procedures in place for the Trust, including, but not limited to, offline storage, or “cold storage”, for a substantial portion of the Trust’s SUI, multiple encrypted private key “shards”, usernames, passwords and 2-step verification, are reasonably designed to safeguard the Trust’s SUI. Nevertheless, the security procedures cannot guarantee the prevention of any loss due to a security breach, software defect or act of God that may be borne by the Trust. Additionally, because a portion of the Trust’s SUI from time to time will be held in hot storage, such SUI will be more vulnerable to a potential hack or other cyberattack that could lead to a loss of Trust assets.

The security procedures and operational infrastructure may be breached due to the actions of outside parties, error or malfeasance of an employee of the Sponsor, a Custodial Entity, or otherwise, and, as a result, an unauthorized party may obtain access to an Account, the relevant private keys (and therefore SUI) or other data of the Trust. Additionally, outside parties may attempt to fraudulently induce employees of the Sponsor or a Custodial Entity to disclose sensitive information in order to gain access to the Trust’s infrastructure. As the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently, or may be designed to remain dormant until a predetermined event and often are not recognized until launched against a target, the Sponsor and the Custodial Entities may be unable to anticipate these techniques or implement adequate preventative measures. Moreover, the Custodial Entities will not be liable for any claims or losses arising out of or relating to the acts and/or omissions of any unauthorized third parties, except to the extent such losses are caused by a Custodial Entity’s negligence, fraud or willful misconduct.

An actual or perceived breach of the accounts associated with the Trust’s Vault Balance and Settlement Balance (the “Accounts”) could harm the Trust’s operations, result in loss of the Trust’s assets, damage the Trust’s reputation and negatively affect the market perception of the effectiveness of the Trust, all of which could in turn reduce demand for the Shares, resulting in a reduction in the value of the Shares. The Trust may also cease operations, the occurrence of which could similarly result in a reduction in the value of the Shares.

SUI transactions are irrevocable and stolen or incorrectly transferred SUI may be irretrievable. As a result, any incorrectly executed SUI transactions could adversely affect the value of the Shares.

SUI transactions are typically not reversible without the consent and active participation of the recipient of the transaction. Once a transaction has been verified and recorded in a block that is added to the Blockchain, an incorrect transfer or theft of SUI generally

will not be reversible and the Trust may not be capable of seeking compensation for any such transfer or theft. Although the Trust’s transfers of SUI will regularly be made to or from the Vault Balance, it is possible that, through computer or human error, or through theft or criminal action, the Trust’s SUI could be transferred from the Trust’s Vault Balance in incorrect amounts or to unauthorized third parties, or to uncontrolled accounts.

Such events have occurred in connection with digital assets in the past. To the extent that the Trust is unable to seek a corrective transaction with such third party or is incapable of identifying the third party which has received the Trust’s SUI through error or theft, the Trust will be unable to revert or otherwise recover incorrectly transferred SUI. The Trust will also be unable to convert or recover its SUI transferred to uncontrolled accounts. To the extent that the Trust is unable to seek redress for such error or theft, such loss could adversely affect the value of the Shares.

The lack of full insurance and shareholders’ limited rights of legal recourse against the Trust, Trustee, Sponsor, Transfer Agent and Custodial Entities expose the Trust and its shareholders to the risk of loss of the Trust’s SUI for which no person or entity is liable.

The Trust is not a banking institution or otherwise a member of the FDIC or Securities Investor Protection Corporation (“SIPC”) and, therefore, deposits held with or assets held by the Trust are not subject to the protections enjoyed by depositors with FDIC or SIPC member institutions. In addition, neither the Trust nor the Sponsor insure the Trust’s SUI.

While the Custodian is required under the Prime Broker Agreement to maintain insurance coverage that is commercially reasonable for the custodial services it provides, and the Custodial Entities have advised the Sponsor that they maintain insurance coverage at commercially reasonable amounts for the digital assets custodied on behalf of clients, including the Trust’s SUI, resulting from theft, shareholders cannot be assured that the Custodian or the Prime Broker will maintain adequate insurance or that such coverage will cover losses with respect to the Trust’s SUI. Moreover, while the Custodian maintains certain capital reserve requirements depending on the assets under custody and to the extent required by applicable law, and such capital reserves may provide additional means to cover client asset losses, the Sponsor does not know the amount of such capital reserves, and neither the Trust nor the Sponsor have access to such information. The Trust cannot be assured that the Custodial Entities will maintain capital reserves sufficient to cover losses with respect to the Trust’s digital assets. Furthermore, Coinbase has represented in securities filings that the total value of crypto assets in its possession and control is significantly greater than the total value of insurance coverage that would compensate Coinbase in the event of theft or other loss of funds.

Furthermore, the Custodial Entities’ aggregate maximum liability with respect to breach of their obligations under the Prime Broker Agreement will not exceed the greater of: (i) the value of the SUI or cash involved in the event, including but not limited to transaction(s) or deliveries(s), giving rise to such liability at the time of the event giving rise to such liability; (ii) the aggregate amount of fees paid by the Trust to the Custodial Entities in respect of the Custodial and Prime Broker Services in the 12-month period prior to the event giving rise to such liability; or (iii) five million U.S. dollars. The Custodian’s total liability under the Prime Broker Agreement will not exceed the greater of: (i) the aggregate amount of fees paid by the Trust to the Custodian in respect of the custodial services in the 12-month period prior to the event giving rise to such liability; or (ii) the value of the SUI on deposit in the Vault Balance at the time of the events giving rise to the liability occurred, the value of which will be determined in accordance with the Prime Broker Agreement.

In addition, the Custodian’s maximum liability in respect of each cold storage address that holds SUI is limited to the “Cold Storage Threshold” of $100 million. The Sponsor monitors the value of SUI deposited in cold storage addresses for whether the Cold Storage Threshold has been met by determining the U.S. dollar value of SUI deposited in each cold storage address on business days. Although the Cold Storage Threshold has never been met for a given cold storage address, to the extent it is met the Trust would not have a claim against the Custodian with respect to the digital assets held in such address to the extent the value exceeds the Cold Storage Threshold. The Custodial Entities and the Trust are not liable to each other for any special, incidental, indirect, punitive, or consequential damages, whether or not the other party had been advised of such losses or knew or should have known of the possibility of such damages.

The shareholders’ recourse against the Sponsor and the Trust’s other service providers for the services they provide to the Trust, including those relating to the provision of instructions relating to the movement of SUI, is limited. Consequently, a loss may be suffered with respect to the Trust’s SUI that is not covered by insurance and for which no person is liable in damages. As a result, the recourse of the Trust or the shareholders, under New York law, is limited.

The Trust may be required, or the Sponsor may deem it appropriate, to terminate and liquidate at a time that is disadvantageous to shareholders.

Pursuant to the terms of the Trust Agreement, the Trust is required to dissolve under certain circumstances. In addition, the Sponsor may, in its sole discretion, dissolve the Trust for a number of reasons, including if the Sponsor determines, in its sole discretion, that it is desirable or advisable for any reason to discontinue the affairs of the Trust. For example, the Sponsor expects that it may be advisable to discontinue the affairs of the Trust if a federal court upholds an allegation that SUI is a security under the federal securities laws, among other reasons. See “Item 1. Business—Description of the Trust Agreement—Termination of the Trust.”

If the Trust is required to terminate and liquidate, or the Sponsor determines in accordance with the terms of the Trust Agreement that it is appropriate to terminate and liquidate the Trust, such termination and liquidation could occur at a time that is disadvantageous to shareholders, such as when the Actual Exchange Rate of SUI is lower than the Index Price was at the time when shareholders purchased their Shares. In such a case, when the Trust’s SUI is sold as part of its liquidation, the resulting proceeds distributed to shareholders will be less than if the Actual Exchange Rate were higher at the time of sale. See “Item 1. Business—Description of the Trust Agreement—Termination of the Trust” for more information about the termination of the Trust, including when the termination of the Trust may be triggered by events outside the direct control of the Sponsor, the Trustee or the shareholders.

The Trust Agreement includes provisions that limit shareholders’ voting rights and restrict shareholders’ right to bring a derivative action.

Under the Trust Agreement, shareholders have limited voting rights and the Trust will not have regular shareholder meetings. Shareholders take no part in the management or control of the Trust. Accordingly, shareholders do not have the right to authorize actions, appoint service providers or take other actions as may be taken by shareholders of other trusts or companies where shares carry such rights. The shareholders’ limited voting rights give almost all control under the Trust Agreement to the Sponsor and the Trustee. The Sponsor may take actions in the operation of the Trust that may be adverse to the interests of shareholders and may adversely affect the value of the Shares.

Moreover, pursuant to the terms of the Trust Agreement, shareholders’ statutory right under Delaware law to bring a derivative action (i.e., to initiate a lawsuit in the name of the Trust in order to assert a claim belonging to the Trust against a fiduciary of the Trust or against a third party when the Trust’s management has refused to do so) is restricted. Under Delaware law, a shareholder may bring a derivative action if the shareholder is a shareholder at the time the action is brought and either (i) was a shareholder at the time of the transaction at issue or (ii) acquired the status of shareholder by operation of law or the Trust’s governing instrument from a person who was a shareholder at the time of the transaction at issue. Additionally, Section 3816(e) of the Delaware Statutory Trust Act specifically provides that a “beneficial owner’s right to bring a derivative action may be subject to such additional standards and restrictions, if any, as are set forth in the governing instrument of the statutory trust, including, without limitation, the requirement that beneficial owners owning a specified beneficial interest in the statutory trust join in the bringing of the derivative action.” In addition to the requirements of applicable law and in accordance with Section 3816(e), the Trust Agreement provides that no shareholder will have the right, power or authority to bring or maintain a derivative action, suit or other proceeding on behalf of the Trust unless two or more shareholders who (i) are not “Affiliates” (as defined in the Trust Agreement and below) of one another and (ii) collectively hold at least 10.0% of the outstanding Shares join in the bringing or maintaining of such action, suit or other proceeding. This provision applies to any derivative actions brought in the name of the Trust other than claims under the federal securities laws and the rules and regulations thereunder.

Due to this additional requirement, a shareholder attempting to bring or maintain a derivative action in the name of the Trust will be required to locate other shareholders with which it is not affiliated and that have sufficient Shares to meet the 10.0% threshold based on the number of Shares outstanding on the date the claim is brought and thereafter throughout the duration of the action, suit or proceeding. This may be difficult and may result in increased costs to a shareholder attempting to seek redress in the name of the Trust in court. Moreover, if shareholders bringing a derivative action, suit or proceeding pursuant to this provision of the Trust Agreement do not hold 10.0% of the outstanding Shares on the date such an action, suit or proceeding is brought, or such shareholders are unable to maintain Share ownership meeting the 10.0% threshold throughout the duration of the action, suit or proceeding, such shareholders’ derivative action may be subject to dismissal. As a result, the Trust Agreement limits the likelihood that a shareholder will be able to successfully assert a derivative action in the name of the Trust, even if such shareholder believes that he or she has a valid derivative action, suit or other proceeding to bring on behalf of the Trust. See “Item 1. Business—Description of the Trust Agreement—The Sponsor—Fiduciary and Regulatory Duties of the Sponsor” for more detail.

The Sponsor is solely responsible for determining the value of the NAV and NAV per Share and any errors, discontinuance or changes in such valuation calculations may have an adverse effect on the value of the Shares.

The Sponsor will determine the Trust’s NAV and NAV per Share on a daily basis as soon as practicable after 4:00 p.m., New York time, on each business day. The Sponsor’s determination is made utilizing data from the operations of the Trust and the Index Price, calculated at 4:00 p.m., New York time, on such day. If the Sponsor determines in good faith that the Index does not reflect an accurate SUI price, then the Sponsor will employ an alternative method to determine the Index Price under the cascading set of rules set forth in “Item 1. Business—Overview of the Sui Industry and Market—SUI Value—The Index and the Index Price—Determination of the Index Price When Index Price is Unavailable.” In the context of applying such rules, the Sponsor may determine in good faith that the alternative method applied does not reflect an accurate SUI price and apply the next alternative method under the cascading set of rules. If the Sponsor determines after employing all of the alternative methods that the Index Price does not reflect an accurate SUI price, the Sponsor will use its best judgment to determine a good faith estimate of the Index Price.

There are no predefined criteria to make a good faith assessment in these scenarios and such decisions will be made by the Sponsor in its sole discretion. The Sponsor may calculate the Index Price in a manner that ultimately inaccurately reflects the price of SUI. To the extent that the NAV, NAV per Share or the Index Price are incorrectly calculated, the Sponsor may not be liable for any error and such misreporting of valuation data could adversely affect the value of the Shares and investors could suffer a substantial loss on their

investment in the Trust. Moreover, the terms of the Trust Agreement do not prohibit the Sponsor from changing the Index Price used to calculate the NAV and NAV per Share of the Trust. Any such change in the Index Price could affect the value of the Shares and investors could suffer a substantial loss on their investment in the Trust.

Extraordinary expenses resulting from unanticipated events may become payable by the Trust, adversely affecting the value of the Shares.

In consideration for the Sponsor’s Fee, the Sponsor has contractually assumed all ordinary-course operational and periodic expenses of the Trust. See “Item 1. Business—Expenses; Sales of SUI.” Extraordinary expenses incurred by the Trust, such as taxes and governmental charges; expenses and costs of any extraordinary services performed by the Sponsor (or any other service provider) on behalf of the Trust to protect the Trust or the interests of shareholders; or extraordinary legal fees and expenses are not assumed by the Sponsor and are borne by the Trust. The Sponsor will cause the Trust to either (i) sell SUI held by the Trust or (ii) deliver SUI in-kind to the Sponsor to pay Trust expenses not assumed by the Sponsor on an as-needed basis. Accordingly, the Trust may be required to sell or otherwise dispose of SUI at a time when the trading prices for those assets are depressed.

The sale or other disposition of assets of the Trust in order to pay extraordinary expenses could have a negative impact on the value of the Shares for several reasons. These include the following factors:

•

The Trust is not actively managed and no attempt will be made to protect against or to take advantage of fluctuations in the prices of SUI. Consequently, if the Trust incurs expenses in U.S. dollars, the Trust’s SUI may be sold at a time when the values of the disposed assets are low, resulting in a negative impact on the value of the Shares.

•

Because the Trust does not generate any income, every time that the Trust pays expenses, it will deliver SUI to the Sponsor or sell SUI. Any sales of the Trust’s assets in connection with the payment of expenses will decrease the amount of the Trust’s assets represented by each Share each time its assets are sold or transferred to the Sponsor.

•

Assuming that the Trust is a grantor trust for U.S. federal income tax purposes, each delivery or sale of SUI by the Trust to pay the Sponsor’s Fee and/or Additional Trust Expenses will be a taxable event to beneficial owners of Shares. Thus, the Trust’s payment of expenses could result in beneficial owners of Shares incurring tax liability without an associated distribution from the Trust. Any such tax liability could adversely affect an investment in the Shares. See “Item 1. Business—Material U.S. Federal Income Tax Consequences.”

The Trust’s delivery or sale of SUI to pay expenses or other operations of the Trust could result in shareholders’ incurring tax liability without an associated distribution from the Trust.

Assuming that the Trust is treated as a grantor trust for U.S. federal income tax purposes, each delivery of SUI by the Trust to pay the Sponsor’s Fee or other expenses and each sale of SUI by the Trust to pay Additional Trust Expenses will be a taxable event to beneficial owners of Shares. Thus, the Trust’s payment of expenses could result in beneficial owners of Shares incurring tax liability without an associated distribution from the Trust. Any such tax liability could adversely affect an investment in the Shares. See “Item 1. Business—Material U.S. Federal Income Tax Consequences.”

The value of the Shares will be adversely affected if the Trust is required to indemnify the Sponsor, the Trustee, the Transfer Agent or the Custodian under the Trust Documents.

Under the Trust Documents, each of the Sponsor, the Trustee, the Transfer Agent and the Custodian has a right to be indemnified by the Trust for certain liabilities or expenses that it incurs without gross negligence, bad faith or willful misconduct on its part. Therefore, the Sponsor, Trustee, Transfer Agent or the Custodian may require that the assets of the Trust be sold in order to cover losses or liability suffered by it. Any sale of that kind would reduce the NAV of the Trust and the value of the Shares.

Intellectual property rights claims may adversely affect the Trust and the value of the Shares.

The Sponsor is not aware of any intellectual property rights claims that may prevent the Trust from operating and holding SUI. However, third parties may assert intellectual property rights claims relating to the operation of the Trust and the mechanics instituted for the investment in, holding of and transfer of SUI. Regardless of the merit of an intellectual property or other legal action, any legal expenses to defend or payments to settle such claims would be extraordinary expenses that would be borne by the Trust through the sale or transfer of its SUI. Additionally, a meritorious intellectual property rights claim could prevent the Trust from operating and force the Sponsor to terminate the Trust and liquidate its SUI. As a result, an intellectual property rights claim against the Trust could adversely affect the value of the Shares.

Pandemics, epidemics and other natural and man-made disasters could negatively impact the value of the Trust’s holdings and/or significantly disrupt its affairs.

Pandemics, epidemics and other natural and man-made disasters could negatively impact demand for digital assets, including SUI, and disrupt the operations of many businesses, including the businesses of the Trust’s service providers. For example, the COVID-19

pandemic had serious adverse effects on the economies and financial markets of many countries, resulting in increased volatility and uncertainty in economies and financial markets of many countries and in the Digital Asset Markets. Moreover, governmental authorities and regulators throughout the world have in the past responded to major economic disruptions, including as a result of the COVID-19 pandemic, with a variety of fiscal and monetary policy changes, such as quantitative easing, new monetary programs and lower interest rates. An unexpected or quick reversal of any such policies, or the ineffectiveness of such policies, could increase volatility in economies and financial market generally, and could specifically increase volatility in the Digital Asset Markets, which could adversely affect the value of SUI and the value of the Shares.

In addition, pandemics, epidemics and other natural and man-made disasters could disrupt the operations of many businesses. For example, in response to the COVID-19 pandemic, many governments imposed travel restrictions and prolonged, closed international borders and enhanced health screenings at ports of entry and elsewhere, which disrupted businesses around the world. While the Sponsor and the Trust were not materially impacted by these events, any disruptions to the Sponsor’s, the Trust’s or the Trust’s service providers’ business operations resulting from business restrictions, quarantines or restrictions on the ability of personnel to perform their jobs as a result of any future pandemic, epidemic or other disaster could have an adverse impact on the Trust’s ability to access critical services and could be disruptive to the affairs of the Trust.

The limited ability to facilitate in-kind creations and redemptions of Shares could have adverse consequences for the Trust.

Authorized Participants must be registered broker-dealers. Registered broker-dealers are subject to various requirements of the federal securities laws and rules, including financial responsibility rules such as the customer protection rule, the net capital rule and record keeping requirements. Although the SEC recently approved orders to permit in-kind creations and redemptions by authorized participants for certain spot digital asset ETP shares there has yet to be definitive regulatory guidance on the specific details of how registered broker-dealers, can comply with SEC rules with respect to transacting in or holding spot SUI. In particular, registered broker-dealers participating in the in-kind creation or redemption of Shares for SUI will need to ensure that they can demonstrate compliance with applicable financial responsibility rules. While compliance with such requirements would be the broker-dealer’s responsibility, a national securities exchange is required to enforce compliance by its member broker-dealers with applicable federal securities law and rules. Only certain Authorized Participants, at present, have the ability to also, through their affiliates, support in-kind creation and redemption activity pursuant to the terms of their participant agreements with the Trust. As of the date of the filing of this Annual Report, Jane Street Capital, LLC and Virtu Americas LLC have executed an agreement providing them with the ability to conduct creations and redemptions in-kind for SUI in addition to conducting creations and redemptions for cash. The Sponsor may engage additional Authorized Participants who are unaffiliated with the Trust in the future, and such Authorized Participants may be able to conduct creations and redemptions in-kind, in cash, or both.

Even with the approval of in-kind creations and redemptions, the Trust’s limited ability to facilitate in-kind creations and redemptions could result in the exchange-traded product arbitrage mechanism failing to function as efficiently as it otherwise would, leading to the potential for the Shares to trade at premiums or discounts to the NAV per Share, and such premiums or discounts could be substantial. Furthermore, if Cash Orders are unavailable, either due to the Sponsor’s decision to reject or suspend such orders or otherwise, Authorized Participants may be limited in their ability to redeem or create Shares, in which case the arbitrage mechanism may not function as efficiently. This could result in impaired liquidity for the Shares, wider bid/ask spreads in secondary trading of the Shares and greater costs to investors and other market participants. In addition, the Trust’s limited ability to facilitate in-kind creations and redemptions, and resulting reliance on cash creations and redemptions, could cause the Sponsor to halt or suspend the creation of redemption of Shares during times of market volatility or turmoil, among other consequences.

Further, there can be no assurance that additional broker-dealers would be willing to serve as Authorized Participants with respect to the in-kind creation and redemption of Shares. Any of these factors could adversely affect the performance of the Trust and the value of the Shares.

Shareholders will not receive the benefits of any forks or airdrops.

The Sui Network operates using open-source protocols, meaning that any user can download the software, modify it and then propose that the users and validators of SUI adopt the modification. When a modification is introduced and a substantial majority of users and validators consent to the modification, the change is implemented and the network remains uninterrupted. However, if less than a substantial majority of users and validators consent to the proposed modification, and the modification is not compatible with the software prior to its modification, the consequence would be what is known as a “hard fork” of the Sui Network, with one group running the pre-modified software and the other running the modified software. The effect of such a fork would be the existence of two versions of Sui running in parallel, yet lacking interchangeability. In addition to forks, a digital asset may become subject to a similar occurrence known as an “airdrop.” In an airdrop, the promoters of a new digital asset announce to holders of another digital asset that such holders will be entitled to claim a certain amount of the new digital asset, generally for free, based on the fact that they hold such other digital

asset. We refer to the right to receive any benefits arising from a fork, airdrop or similar event as an “Incidental Right” and any such virtual currency acquired through an Incidental Right as “IR Virtual Currency.”

With respect to any fork, airdrop or similar event, the Sponsor will cause the Trust to irrevocably abandon the Incidental Rights and any IR Virtual Currency associated with such event. As such, shareholders will not receive the benefits of any forks, and the Trust is not able to participate in any airdrop.

In the event the Sponsor seeks to change the Trust’s policy with respect to Incidental Rights or IR Virtual Currency, an application would need to be filed with the SEC by NYSE Arca seeking approval to amend its listing rules to permit the Trust to distribute the Incidental Rights or IR Virtual Currency in-kind to an agent of the shareholders for resale by such agent. However, there can be no assurance as to whether or when the Sponsor would make such a decision, or when NYSE Arca will seek or obtain this approval, if at all.

Even if such regulatory approval is sought and obtained, shareholders may not receive the benefits of any forks, the Trust may not choose, or be able, to participate in an airdrop, and the timing of receiving any benefits from a fork, airdrop or similar event is uncertain. Any inability to recognize the economic benefit of a hard fork or airdrop could adversely affect the value of the Shares.

Coinbase Global serves as the SUI custodian and prime execution agent for several competing exchange-traded SUI products, which could adversely affect the Trust’s operations and ultimately the value of the Shares.

The Prime Broker and Custodian are both affiliates of Coinbase Global. As of the date hereof, Coinbase Global is the largest publicly traded digital asset company in the world by market capitalization and is also the largest digital asset custodian in the world by assets under custody. By virtue of its leading market position and capabilities, and the relatively limited number of institutionally-capable providers of digital asset brokerage and custody services, Coinbase Global serves as the SUI custodian and prime execution agent for several competing exchange-traded SUI products. Therefore, Coinbase Global plays a critical role in supporting the U.S. spot SUI exchange-traded product ecosystem, and its size and market share create the risk that Coinbase Global may fail to properly resource its operations to adequately support all such products that use its services, which could harm the Trust, the shareholders and the value of the Shares. If Coinbase Global were to favor the interests of certain products over others, it could result in inadequate attention or comparatively unfavorable commercial terms to less favored products, which could adversely affect the Trust’s operations and ultimately the value of the Shares.

Certain of the Authorized Participants engaged by the Trust may serve in a similar capacity for competing exchange-traded SUI products, which could adversely affect the arbitrage mechanism, the Trust’s operations, the performance of the Trust and ultimately the value of the Shares.

Certain of the Authorized Participants engaged by the Trust may serve in a similar capacity for competing exchange-traded SUI products. As a result, the Authorized Participants may be unable to adequately support all of the exchange-traded SUI products that use their respective services. This risk may also be exacerbated as a consequence of the price and volatility of SUI, as well as the amount of SUI that is required to create or redeem Shares of the Trust. Moreover, the Authorized Participants may choose to facilitate creations and redemptions for competing products rather than for the Trust, including as a result of, among other things, how effectively the arbitrage mechanism of the Trust functions, the liquidity for the Shares, the bid/ask spreads in secondary trading of the Shares and the costs associated with creating and redeeming Shares of the Trust, in each case relative to competing products. In addition, given the relatively limited number of market participants that could serve as Authorized Participants of the Trust, the Trust may not be able to engage other providers to serve as Authorized Participants. If any or all of the Authorized Participants were to cease to act in their capacity as Authorized Participants of the Trust, or if any of the Authorized Participants were to favor creating and redeeming shares of competing products over those of the Trust, the Trust may receive inadequate attention or be subject to comparatively unfavorable commercial terms, which could adversely affect the arbitrage mechanism, the Trust’s operations, the performance of the Trust and ultimately the value of the Shares. See also “—Risk Factors Related to the Trust and the Shares—Competition from the emergence or growth of other digital assets could have a negative impact on the price of SUI and adversely affect the value of the Shares.”

Shareholders that are not Authorized Participants may only purchase or sell their Shares in secondary trading markets, and the conditions associated with trading in secondary markets may adversely affect investors’ investment in the Shares.

Only Authorized Participants may purchase or redeem Baskets. All other investors that desire to purchase or sell Shares must do so through NYSE Arca or in other markets, if any, in which the Shares may be traded. Shares may trade at a premium or discount to the NAV per Share.

The Sponsor may implement restatements, amendments or supplements to the Trust Agreement that may not necessarily align with shareholder interests

There can be no assurance that the Sponsor will implement restatements, amendments or supplements that align with the interests of shareholders. To the extent shareholders do not agree with future amendments to the Trust Agreement, shareholders will not have

any ability to consent or object to such amendments, and the shareholders’ sole recourse will be to divest or, through an Authorized Participant, redeem their Shares prior to the effective date of such amendments.

The Sponsor may implement restatements, amendments or supplements to the Trust Agreement that may increase risk to the Trust’s intended tax treatment

It is possible that, in the future, the Sponsor will implement restatements, amendments or supplements to the Trust Agreement that could adversely affect the intended tax treatment of the Trust as a grantor trust for U.S. federal income tax purposes, including on the receipt of an opinion of counsel to the effect that doing so should not cause the Trust to fail to qualify as a grantor trust for those purposes. There can be no assurance that the IRS or any court will agree with any such position, or that the Trust will not cease to qualify as a grantor trust as a result of any such restatement, amendment or supplement.

A single shareholder controls over a majority of the Shares representing ownership in the Trust, which could limit the ability of other shareholders to exercise voting influence or otherwise adversely impact the value of the Shares.

On February 17, 2026, the Trust and the Sui Foundation entered into a subscription agreement (the “Sui Foundation Subscription Agreement”), pursuant to which the Sui Foundation acquired Shares of the Trust in a private offering for an aggregate purchase price of approximately 20,000,000 SUI tokens, which constitutes a majority of the Shares representing ownership in the Trust. See “Business—Overview of the Sui Industry and Market—Sui Foundation Investment.”

As a result of such investment, a single shareholder has control over the limited voting rights granted to the shareholders and has the ability to control the outcome of virtually all matters presented to our shareholders for their approval. Such shareholder’s interests may conflict with the interests of the Trust’s other shareholders. As long as a single shareholder continues to own a significant or majority percentage of our Shares, this concentrated ownership or influence could impede the development of an active trading market in our Shares or adversely affect an investment in the Shares. Additionally, sales of substantial amounts of Shares by such shareholder, or the perception that these sales may occur, could cause the price of the Shares to experience significant volatility and/or decline, including at a resulting discount to the Trust’s NAV per Share, which would adversely impact the value of the Shares.

Risk Factors Related to the Regulation of Digital Assets, the Trust and the Shares

The test for determining whether a particular digital asset is a “security” is complex and difficult to apply, and the outcome is difficult to predict. Whether a digital asset is a security, or offers and sales of a digital asset are securities transactions under the federal securities laws depends on whether it is included in the lists of instruments making up the definition of “security” in such laws. Digital assets as such do not appear in any of these lists, although each list includes the terms “investment contract” and “note,” and the SEC has typically analyzed whether a particular digital asset, is a security or the offer and sale of a digital asset is a securities transaction by reference to whether it meets the tests developed by the federal courts interpreting these terms, known as the Howey and Reves tests, respectively. For many digital assets, whether or not the Howey or Reves tests are met is difficult to resolve definitively, and substantial legal arguments can often be made both in favor of and against a particular digital asset qualifying as a security or a particular offer and sale of a digital asset qualifying as a securities transaction under one or both of the Howey and Reves tests. Adding to the complexity, the SEC staff has indicated that the security status of a particular digital asset can change over time as the relevant facts evolve.

The SEC, at least under the prior administration, has stated that certain digital assets may be considered “securities” or offered and sold in securities transactions under the U.S. federal securities laws. For example, the SEC under former SEC Chair Gensler’s leadership brought enforcement actions against the issuers and promoters of several other digital assets on the basis that the digital assets in question are securities or offered and sold in securities transactions, as well as against Digital Asset Trading Platforms for allegedly operating unregistered securities exchanges on the basis that certain of the digital assets traded on their platforms involved securities transactions.

On March 17, 2026, the SEC issued a Commission-level interpretation clarifying how the federal securities laws apply to certain crypto assets and transactions involving crypto assets. The SEC interpretation provides a taxonomy for digital commodities, digital collectibles, digital tools, stablecoins and digital securities; addresses how a non-security crypto asset may become subject to, and how it may cease to be subject to, an investment contract; and clarifies the application of federal securities laws to airdrops, protocol mining, protocol staking and the wrapping of a non-security crypto asset. The interpretation lists 18 crypto assets that, as of the date of the release, qualify as digital commodities, including BTC, ETH, SOL and XRP. The interpretation notes 16 of these crypto assets currently underlie futures contracts that have been made available to trade on a designated contract market operating under the regulatory oversight of the CFTC, but that it is not necessary that a crypto asset underlie such a futures contract to be a digital commodity. The CFTC joined the interpretation to provide guidance that the CFTC and its staff will administer the CEA consistent with the SEC’s interpretation. Under the SEC’s interpretation, even if a crypto asset is deemed to be a non-security crypto asset (such as a “digital commodity”), the interpretation takes the view that the non-security crypto asset may still be subject to an investment contract, even in the secondary market—and thus secondary market transactions, even in such non-security crypto assets, might be subject to the federal securities laws. Additional guidance and rulemaking from the SEC may be forthcoming, as previewed in recent statements by the current SEC Chairman Paul Atkins.

As part of determining whether SUI is a security or a transaction in SUI by the Sponsor is a securities transaction, for purposes of the federal securities laws, the Sponsor takes into account a number of factors, including the various definitions of “security” under the federal securities laws and federal court decisions interpreting elements of these definitions, such as the U.S. Supreme Court’s decisions in the Howey and Reves cases and their progeny, as well as Commission-level guidance, reports, orders, press releases, public statements and speeches by the SEC, its commissioners and its staff providing guidance on when a digital asset may be a security or when an offer and sale of a digital asset may be a securities transaction for purposes of the federal securities laws.

The Sponsor also discusses the security status of SUI and the Sponsor’s transactions in SUI with external counsel, and has received a memorandum regarding the status of SUI and the Sponsor’s transactions in SUI under the federal securities laws from external counsel. As is the case with SUI, analyses from counsel typically review the often-complex facts surrounding a particular digital asset’s underlying technology, creation, use case and usage development, distribution and secondary-market trading characteristics as well as contributions of and marketing or promotional efforts by the individuals or organizations who appear to be involved in these activities, among other relevant facts, usually drawing on publicly available information. This information, usually found on the internet, often includes both information that originated with or is attributed to such individuals or organizations, as well as information from third-party sources and databases that may or may not have a connection to such individuals or organizations, and the availability and nature of such information can change over time. The Sponsor and counsel often have no independent means of verifying the accuracy or completeness of such information, and therefore of necessity usually must assume that such information is materially accurate and complete for purposes of the Howey and Reves analyses. After having gathered this information, counsel typically analyzes it in light of the Howey and Reves tests, in order to inform a judgment as to whether or not a federal court would conclude that the digital asset, or transactions in the digital asset, in question is or is not a security, or are or are not securities transactions, respectively, for purposes of the federal securities laws. Often, certain factors appear to support a conclusion that the digital asset in question, or transactions in the digital asset, is a security, or are or are not securities transactions, respectively, while other factors appear to support the opposite conclusion, and in such a case counsel endeavors to weigh the importance and relevance of the competing factors. This analytical process is further complicated by the fact that, at present, federal judicial case law applying the relevant tests to digital assets is limited and in some situations inconsistent, with no federal appellate court having considered the question on the merits, as well as the fact that because each digital asset presents its own unique set of relevant facts, it is not always possible to directly analogize the analysis of one digital asset to another. Because of this factual complexity and the current lack of a well-developed body of federal case law applying the relevant tests to a variety of different fact patterns, the Sponsor has not in the past received, and currently does not expect that it would be able to receive, “opinions” of counsel stating that a particular digital asset, or transactions in the digital asset, is or is not a security, or are or are not securities transactions, respectively, for federal securities law purposes. The Sponsor understands that as a matter of practice, counsel is generally able to render a legal “opinion” only when the relevant facts are substantially ascertainable and the applicable law is both well-developed and settled. As a result, given the relative novelty of digital assets, the challenges inherent in fact-gathering for particular digital assets, and the fact that federal courts have only recently been tasked with adjudicating the applicability of federal securities law to digital assets, the Sponsor understands that at present counsel is generally not in a position to render a legal “opinion” on the securities law status of SUI or any other particular digital asset.

Through this process the Sponsor believes that it is applying the proper legal standards in determining that SUI is not a security and the Sponsor’s transactions in SUI are not securities transactions in light of the uncertainties inherent in the Howey and Reves tests. However, such policies and procedures are risk-based judgments made by the Sponsor and not a legal standard or determination binding on any regulatory body or court. In light of these uncertainties and the fact-based nature of the analysis, the Sponsor acknowledges that the SEC or a court may take a contrary position; and the Sponsor’s conclusion, even if reasonable under the circumstances, would not preclude legal or regulatory action based on the presence of a security.

If the Sponsor determines that SUI, or transactions in SUI, are a security or securities transactions, respectively, under the federal securities laws, whether that determination is initially made by the Sponsor itself, or because a federal court upholds an allegation that SUI is a security, the Sponsor does not intend to permit the Trust to continue holding SUI in a way that would violate the federal

securities laws (and therefore would either dissolve the Trust or potentially seek to operate the Trust in a manner that complies with the federal securities laws, including the Investment Company Act). Because the legal tests for determining whether a digital asset or transactions in the digital asset, are or are not a security or securities transactions, respectively, often leave room for interpretation, for so long as the Sponsor believes there to be good faith grounds to conclude that the Trust’s SUI is not a security, the Sponsor does not intend to dissolve the Trust on the basis that SUI could at some future point be finally determined to be a security.

Any enforcement action by the SEC or a state securities regulator asserting that SUI, or transactions in SUI, are a security, or securities transactions, respectively, or a court decision to that effect, would be expected to have an immediate material adverse impact on the trading value of SUI, as well as the Shares. This is because the market structure behind most digital assets are incompatible with regulations applying to transactions in securities. If a digital asset or transactions in that digital asset are determined to be a security or securities transactions, respectively, it is likely to become difficult or impossible for the digital asset to be traded, cleared or custodied in the United States through the same channels used by non-security digital assets, which in addition to materially and adversely affecting the trading value of the digital asset is likely to significantly impact its liquidity and market participants’ ability to convert the digital asset into U.S. dollars. Any assertion that a digital asset or transactions in that digital asset are a security or securities transactions, respectively, by the SEC or another regulatory authority may have similar effects.

For example, in 2020 the SEC filed a complaint against the issuer of XRP, Ripple Labs, Inc., and two of its executives, alleging that they raised more than $1.3 billion through XRP sales that should have been registered under the federal securities laws, but were not. In the years prior to the SEC’s action, XRP’s market capitalization at times reached over $140 billion. However, in the weeks following the SEC’s complaint, XRP’s market capitalization fell to less than $10 billion, which was less than half of its market capitalization in the days prior to the complaint. Subsequently, in July 2023, the District Court for the Southern District of New York held that while XRP is not a security, certain sales of XRP to certain buyers (but not other types of sales to other buyers) amounted to “investment contracts” under the Howey test. The District Court entered a final judgment in the case on August 7, 2024 and the parties each dismissed their appeals to the Second Circuit on August 7, 2025.

Likewise, in the days following the announcement of SEC enforcement actions against certain digital asset issuers and trading platforms, the prices of various digital assets have declined significantly and may continue to decline as such cases advance through the federal court system. Furthermore, the decisions in cases involving digital assets have resulted in seemingly inconsistent views of different district court judges, including one that explicitly disagreed with the analysis underlying the decision regarding XRP, which underscore the continuing uncertainty around which digital assets, or transactions in digital assets, are securities and what the correct analysis is to determine each digital asset’s status. For example, the conflicting district court opinions and analyses demonstrate that factors such as how long a digital asset has been in existence, how widely held it is, how large its market capitalization is, the manner in which it is offered, sold or promoted, and whether it has actual use in commercial transactions, ultimately may have limited or no bearing on whether the SEC, a state securities regulator or any particular court will find it to be a security.

In addition, if SUI is determined to be a security by a federal court or transactions in SUI are determined to be securities transactions by a federal court, the Trust could be considered an unregistered “investment company” under the Investment Company Act, which could necessitate the Trust’s liquidation. In this case, the Trust and the Sponsor may be deemed to have participated in an illegal offering of investment company securities and there is no guarantee that the Sponsor will be able to register the Trust under the Investment Company Act at such time or take such other actions as may be necessary to ensure the Trust’s activities comply with applicable law, which could force the Sponsor to liquidate the Trust.

Moreover, whether or not the Sponsor or the Trust were subject to additional regulatory requirements as a result of any determination that the Trust’s assets include securities or the Trust’s transactions in digital assets constitute securities transactions, the Sponsor may nevertheless decide to terminate the Trust, in order, if possible, to liquidate the Trust’s assets while a liquid market still exists. For example, in response to the SEC’s action against the issuer of the digital asset XRP, certain significant market participants announced they would no longer support XRP and announced measures, including the delisting of XRP from major Digital Asset Trading Platforms, resulting in the Sponsor’s conclusion that it was likely to be increasingly difficult for U.S. investors, including Grayscale XRP Trust ETF, an affiliate of the Trust, to convert XRP into U.S. dollars. The Sponsor subsequently dissolved Grayscale XRP Trust (XRP) and liquidated its assets. The Sponsor has since established a new investment vehicle that holds XRP, Grayscale XRP Trust ETF. If the SEC or a federal court were to determine that SUI is a security or transactions in SUI are securities transactions, it is likely that the value of the Shares of the Trust would decline significantly. Furthermore, if a federal court upholds an allegation that SUI is a security or transactions in SUI are securities transactions, the Trust itself may be terminated and, if practical, its assets liquidated.

Regulatory changes or actions by the U.S. Congress or any U.S. federal or state agencies may affect the value of the Shares or restrict the use of SUI, validating activity or the operation of the Sui Network or the Digital Asset Markets in a manner that adversely affects the value of the Shares.

As digital assets have grown in both popularity and market size, the U.S. Congress and a number of U.S. federal and state agencies (including FinCEN, OFAC, SEC, CFTC, FINRA, the Consumer Financial Protection Bureau (“CFPB”), the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the IRS, the Office of the Comptroller of the Currency, the

Federal Deposit Insurance Corporation, the Federal Reserve and state financial institution and securities regulators) have been examining the operations of digital asset networks, digital asset users and the Digital Asset Markets, with particular focus on the extent to which digital assets can be used to launder the proceeds of illegal activities, evade sanctions, or fund criminal or terrorist enterprises and the safety and soundness of trading platforms and other service providers that hold or custody digital assets for users. Many of these state and federal agencies have issued consumer advisories regarding the risks posed by digital assets to investors. Ongoing and future regulatory actions with respect to digital assets generally or SUI in particular may alter, perhaps to a materially adverse extent, the nature of an investment in the Shares or the ability of the Trust to continue to operate.

On January 23, 2025, President Trump issued an executive order titled “Strengthening American Leadership in Digital Financial Technology” aimed at supporting “the responsible growth and use of digital assets, blockchain technology, and related technologies across all sectors of the economy.” The Executive Order also established an interagency working group that is tasked with “proposing a Federal regulatory framework governing the issuance and operation of digital assets” in the United States. Pursuant to this Executive Order, the working group released a report in July 2025 outlining the administration's recommendations to Congress and various agencies reflecting the administration’s “pro-innovation mindset toward digital assets and blockchain technologies.” In particular, the report recommends that Congress enact legislation regarding self custody of digital assets, clarifying the applicability of Bank Secrecy Act obligations with respect to digital asset service providers, granting the CFTC authority to regulate spot markets in non-security digital assets, prohibiting the adoption of a CBDC, and clarifying tax laws as relevant to digital assets. In addition, the report recommends that agencies reevaluate existing guidance on digital asset activities, use existing authorities to enable the trading of digital assets at the federal level, embrace DeFi, launch or relaunch crypto innovation efforts, and promote U.S. private sector leadership in the responsible development of cross-border payments and financial markets technologies, among others.

There have also been several bills introduced in Congress that propose to establish additional regulation and oversight of the digital asset markets. For example, the CLARITY Act was passed by the House of Representatives in July 2025, which would, if enacted, regulate digital asset markets and digital asset trading platforms in the United States. In addition, also in July 2025, the Guiding and Establishing National Innovation for U.S. Stablecoins Act of 2025 (the “GENIUS Act”) became the first federal law specifically regulating the issuance, custody and other stablecoin-related matters in the United States. It is difficult to predict whether, or when, the CLARITY Act or another bill that would regulate digital asset markets and digital asset trading platforms may become law or what any such bill may entail. It is difficult to predict whether, or when, any of these developments will lead to Congress granting additional authorities to the SEC or other regulators, what the nature of such additional authorities might be, how additional legislation and/or regulatory oversight might impact the ability of Digital Asset Markets to function or how any new regulations or changes to existing regulations might impact the value of digital assets generally and SUI held by the Trust specifically. The consequences of increased federal regulation of digital assets and digital asset activities could have a material adverse effect on the Trust and the Shares.

Law enforcement agencies have often relied on the transparency of blockchains to facilitate investigations. However, certain privacy-enhancing features have been, or are expected to be, introduced to a number of digital asset networks, including the Sui Network. These features, including those adopted by the Sui Network or which may be introduced on the Sui Network in the future, may provide law enforcement agencies with less visibility into transaction-level data. Europol, the European Union’s law enforcement agency, released a report in October 2017 noting the increased use of privacy-enhancing digital assets like Zcash and Monero in criminal activity on the internet. In August 2022, OFAC banned all U.S. citizens from using Tornado Cash, a digital asset protocol designed to obfuscate blockchain transactions, by adding certain Ethereum wallet addresses associated with the protocol to its Specially Designated Nationals and Blocked Persons List. A large portion of Ethereum validators globally, as well as notable industry participants such as Centre, the issuer of the USDC stablecoin, have reportedly complied with the sanctions and blacklisted the sanctioned addresses from interacting with their networks. In October 2023, FinCEN issued a notice of proposed rulemaking that identified convertible virtual currency (CVC) mixing as a class of transactions of primary money laundering concern and proposed requiring covered financial institutions to implement certain recordkeeping and reporting requirements on transactions that covered financial institutions know, suspect, or have reason to suspect involve CVC mixing within or involving jurisdictions outside the United States. In April 2024, the DOJ arrested and charged the developers of the Samourai Wallet mixing service with conspiracy to commit money laundering and conspiracy to operate an unlicensed money transmitting business. In May 2024, a co-founder of Tornado Cash was sentenced to more than five years imprisonment in the Netherlands for developing Tornado Cash on the basis that he had helped launder more than $2 billion worth of digital assets through Tornado Cash. In August 2025, a co-founder of Tornado Cash was convicted of conspiracy to operate an unlicensed money transmitting business, but a mistrial was declared with respect to charges of conspiracy to commit money laundering and conspiracy to violate U.S. sanctions. Future additional regulatory action with respect to privacy-enhancing digital assets is possible.

SUI’s initial manner of sale closely resembles that of certain digital assets found to be securities, and a determination that SUI is a “security” may adversely affect the value of SUI and an investment in the Shares, and result in potentially extraordinary, nonrecurring expenses to, or termination of, the Trust.

Through enforcement actions and other statements, the SEC and its staff under prior leadership have taken the position that a digital asset’s initial manner of sale may be a key factor in determining whether that digital asset was a security, at least at the time of the digital asset’s delivery as part of that sale. This has meant that many blockchain startups that have offered digital assets to the public in the form of initial coin offerings, also known as ICOs, have been found to have engaged in illegal unregistered distributions

of securities. One variant of an ICO involves a digital asset being sold through a Simple Agreement for Future Tokens, or a SAFT. Under a SAFT, a purchaser agrees to contribute funds to enable the development of a digital asset network in exchange for an agreement by the developer to deliver digital assets in the future, once the network becomes operational. The legal theory behind the SAFT is that, while the SAFT itself may be an “investment contract” and thus a “security” under the federal securities laws (and is therefore typically offered in reliance on an exemption from registration), the tokens themselves should not be securities at the time of their delivery because at that time the network will be operational and the tokens will have real consumptive uses, rather than representing an investment to fund the initial development work.

The SEC has cast doubt on the legal argument underpinning the SAFT structure, and has litigated in federal court at least two significant enforcement actions involving digital assets sold under SAFTs, arguing in each case that the digital assets sold under the SAFTs, and not just the SAFTs themselves, were securities. In March 2020, the SEC obtained a preliminary injunction barring Telegram Group, Inc. from conducting an unregistered distribution of digital assets known as Grams, on the grounds that Grams were securities under the federal securities laws, notwithstanding the fact that they had been sold under a SAFT. Telegram Group ultimately agreed to return $1.2 billion to investors and to pay a $18.5 million civil penalty. Similarly, in September 2020 the SEC won a motion for summary judgment against Kik Interactive, Inc., persuading the court that Kik Interactive’s sale of digital assets, called Kin, through a SAFT structure should be integrated with Kik Interactive’s separate public sale of Kin (which the court held to be illegal), as the sales were conducted using the same marketing efforts, involved the same asset, and were conducted very close in time to one another. Kik Interactive ultimately agreed to pay a $5 million civil penalty. The SEC in December 2020 filed a complaint against the issuer of XRP, Ripple Labs, Inc., and two of its executives, alleging that Ripple Labs and its executives raised over $1.3 billion through XRP sales that should have been registered under the federal securities laws, but were not. Multiple digital assets the SEC alleged to be securities in the Coinbase, Binance and Kraken Complaints were first sold to the public in similar circumstances or ICOs. Subsequently, in July 2023, the District Court for the Southern District of New York held that while XRP is not a security, certain sales of XRP to certain buyers amounted to “investment contracts” under the Howey test. For a discussion of the evolution of the SEC’s complaint against Ripple Labs, see “Risk Factors—Risk Factors Related to the Regulation of Digital Assets, the Trust and the Shares—A determination that SUI or any other digital asset is a “security” may adversely affect the value of SUI and the value of the Shares, and result in potentially extraordinary, nonrecurring expenses to, or termination of, the Trust.”

As discussed in “A determination that SUI or any other digital asset is a “security” may adversely affect the value of SUI and the value of the Shares, and result in potentially extraordinary, nonrecurring expenses to, or termination of, the Trust,” the SEC issued a Commission level interpretation of the federal securities laws that states that a non-security crypto asset may become subject to an investment contract and remain subject to the investment contract in secondary markets transactions.

If SUI is determined to be a “security” or transactions in SUI are determined to be securities transactions under federal or state securities laws by the SEC or a state regulatory agency, or in a proceeding in a court of law or otherwise, it will have material adverse consequences for SUI and an investment in the Shares. See “A determination that SUI or any other digital asset is a “security” may adversely affect the value of SUI and the value of the Shares, and result in potentially extraordinary, nonrecurring expenses to, or termination of, the Trust” for a discussion of these consequences. As such, any determination that SUI or transactions in that digital asset are a security under federal or state securities laws may adversely affect the value of SUI and, as a result, an investment in the Shares.

Competing industries may have more influence with policymakers than the digital asset industry, which could lead to the adoption of laws and regulations that are harmful to the digital asset industry.

The digital asset industry is relatively new, although its influence over public policy is increasing, and it may not have the same access to policymakers and lobbying organizations in many jurisdictions compared to industries with which digital assets may be seen to compete, such as banking, payments and consumer finance. Competitors from other, more established industries may have greater access to and influence with governmental officials and regulators and may be successful in persuading these policymakers that digital assets require heightened levels of regulation compared to the regulation of traditional financial services. As a result, new laws and regulations may be proposed and adopted in the United States and elsewhere, or existing laws and regulations may be interpreted in new ways, that disfavor or impose compliance burdens on the digital asset industry or digital asset platforms, which could adversely impact the value of SUI and therefore the value of the Shares.

Various foreign jurisdictions have, and may continue to adopt laws, regulations or directives that affect the digital asset network, the Digital Asset Markets, and their users, particularly Digital Asset Trading Platforms and service providers that fall within such jurisdictions’ regulatory scope. For example, if foreign jurisdictions in addition to China were to ban or otherwise restrict validating activity, including by regulating or limiting manufacturers’ ability to produce or sell semiconductors or hard drives in connection with

validating, it would have a material adverse effect on digital asset networks (including the Sui Network), the Digital Asset Market, and as a result, impact the value of the Shares.

A number of foreign jurisdictions have recently taken regulatory action aimed at digital asset activities. China has made transacting in cryptocurrencies illegal for Chinese citizens in mainland China, and additional restrictions may follow. Both China and South Korea have banned initial coin offerings entirely and regulators in other jurisdictions, including Canada, Singapore and Hong Kong, have opined that initial coin offerings may constitute securities offerings subject to local securities regulations. The United Kingdom’s Financial Conduct Authority published final rules in October 2020 banning the sale of derivatives and exchange-traded notes that reference certain types of digital assets, contending that they are “ill-suited” to retail investors citing extreme volatility, valuation challenges and association with financial crime. A new law, the Financial Services and Markets Act 2023 (“FSMA”), received royal assent in June 2023. The FSMA brings digital asset activities within the scope of existing laws governing financial institutions, markets and assets. In addition, the Parliament of the European Union approved the text of the Markets in Crypto-Assets Regulation (“MiCA”) in April 2023, establishing a regulatory framework for digital asset services across the European Union. Certain parts of MiCA became effective as of June 2024 and the remainder became effective as of December 2024. MiCA is intended to serve as a comprehensive regulation of digital asset markets and imposes various obligations on digital asset issuers and service providers. The main aims of MiCA are industry regulation, consumer protection, prevention of market abuse and upholding the integrity of digital asset markets. See “Item 1. Business—Overview of the Sui Industry and Market—Government Oversight.”

Foreign laws, regulations or directives may conflict with those of the United States and may negatively impact the acceptance of one or more digital assets by users, merchants and service providers outside the United States and may therefore impede the growth or sustainability of the digital asset economy in the European Union, China, Japan, Russia and the United States and globally, or otherwise negatively affect the value of SUI. Moreover, other events, such as the interruption in telecommunications or internet services, cyber-related terrorist acts, civil disturbances, war or other catastrophes, could also negatively affect the digital asset economy in one or more jurisdictions. For example, Russia’s invasion of Ukraine on February 24, 2022 led to volatility in digital asset prices, with an initial steep decline followed by a sharp rebound in prices. The effect of any future regulatory change or other events on the Trust or SUI is impossible to predict, and such change could be substantial and adverse to the Trust and the value of the Shares.

If regulators subject an Authorized Participant, the Trust or the Sponsor to regulation as a money service business or money transmitter, this could result in extraordinary expenses to the Authorized Participant, the Trust or the Sponsor and also result in decreased liquidity for the Shares.

To the extent that the activities of any Authorized Participant, the Trust or the Sponsor cause it to be deemed a “money services business” under the regulations promulgated by FinCEN, such Authorized Participant, the Trust or the Sponsor may be required to comply with FinCEN regulations, including those that would mandate the Authorized Participant, the Trust or the Sponsor to implement anti-money laundering programs, make certain reports to FinCEN and maintain certain records. Similarly, the activities of an Authorized Participant, the Trust or the Sponsor may require it to be licensed as a money transmitter or as a digital asset business, such as under the NYDFS’ BitLicense regulations or California’s Digital Financial Assets Law, once effective.

Such additional regulatory obligations may cause the Authorized Participant, the Trust or the Sponsor to incur extraordinary expenses. If the Authorized Participant, the Trust or the Sponsor decided to seek the required licenses, there is no guarantee that they will timely receive them. An Authorized Participant may instead decide to terminate its role as Authorized Participant of the Trust, or the Sponsor may decide to discontinue and wind up the Trust. An Authorized Participant’s decision to cease acting as such may decrease the liquidity of the Shares, which could adversely affect the value of the Shares, and termination of the Trust in response to the changed regulatory circumstances may be at a time that is disadvantageous to the shareholders.

Additionally, to the extent an Authorized Participant, the Trust or the Sponsor is found to have operated without appropriate state or federal licenses, or registration, it may be subject to investigation, administrative or court proceedings, and civil or criminal monetary fines and penalties, all of which would harm the reputation of the Trust or the Sponsor, decrease the liquidity, and have a material adverse effect on the price of the Shares.

Statutory or regulatory changes or interpretations could obligate the Trust or the Sponsor to register and comply with new regulations, resulting in potentially extraordinary, nonrecurring expenses to the Trust.

Current and future legislation, CFTC and SEC rulemaking and other regulatory developments may impact the manner in which SUI is treated. In particular, SUI may be classified by the CFTC as a “commodity interest” under the CEA or may be classified by the SEC as a “security” under U.S. federal securities laws. It is possible that a new Administration and Congress in the United States creates a new classification for digital assets. For example, the current draft of the CLARITY Act would add “digital commodities” to the list of assets that are commodity interests under the CEA. The Sponsor and the Trust cannot be certain as to how future regulatory developments will impact the treatment of SUI under the law. In the face of such developments, the required registrations and compliance steps may result in extraordinary, nonrecurring expenses to the Trust. If the Sponsor decides to terminate the Trust in response to the changed regulatory circumstances, the Trust may be dissolved or liquidated at a time that is disadvantageous to shareholders.

To the extent that SUI is deemed to fall within the definition of a “commodity interest” under the CEA, due to the passage of the CLARITY Act or otherwise, the Trust and the Sponsor may be subject to additional regulation under the CEA and CFTC regulations. The Sponsor may be required to register as a commodity pool operator or commodity trading adviser with the CFTC and become a member of the National Futures Association and may be subject to additional regulatory requirements with respect to the Trust, including disclosure and reporting requirements. These additional requirements may result in extraordinary, recurring and/or nonrecurring expenses of the Trust, thereby materially and adversely impacting the Shares. If the Sponsor determines not to comply with such additional regulatory and registration requirements, the Sponsor will terminate the Trust. Any such termination could result in the liquidation of the Trust’s SUI at a time that is disadvantageous to shareholders.

To the extent that SUI is determined to be a security under U.S. federal securities laws, the Trust and the Sponsor may be subject to additional requirements under the Investment Company Act and the Sponsor may be required to register as an investment adviser under the Investment Advisers Act. Such additional registration may result in extraordinary, recurring and/or non-recurring expenses of the Trust, thereby materially and adversely impacting the Shares. If the Sponsor determines not to comply with such additional regulatory and registration requirements, the Sponsor will terminate the Trust. Any such termination could result in the liquidation of the Trust’s SUI at a time that is disadvantageous to shareholders.

The treatment of the Trust for U.S. federal income tax purposes is uncertain.

In particular, the Staking Condition has been satisfied as to the particular form of Staking described herein, and the Sponsor intends to continue to take the position that the Trust is properly treated as a grantor trust for U.S. federal income tax purposes and that any Staking activity undertaken by the Trust in compliance with the opinion, ruling or other guidance relied upon to satisfy the Staking Condition will not prevent the Trust from continuing to qualify as a grantor trust for such purposes. The IRS recently issued a revenue procedure providing a staking safe harbor for certain grantor trust vehicles whose beneficial interests are listed and traded on a national securities exchange (the “2025 Revenue Procedure”), but certain aspects of the 2025 Revenue Procedure are unclear, and therefore the Trust may not currently satisfy all conditions of the safe harbor. Accordingly, due to the uncertainty regarding the ability of a grantor trust to engage in Staking activities, there can be no assurance that the Internal Revenue Service (“IRS”) or any court would agree with this position (or with any opinion of counsel delivered to the Sponsor in support thereof). Therefore, the Trust might cease to qualify as a grantor trust for U.S. federal income tax purposes.

The Trust has taken certain positions with respect to the tax consequences of Incidental Rights and its receipt of IR Virtual Currency. If the IRS were to disagree with, and successfully challenge, any of these positions the Trust might not qualify as a grantor trust. In addition, the Pre-Creation/Redemption Abandonment Notices (as defined herein) provide that the Trust will irrevocably abandon, effective immediately prior to each Creation Time or Redemption Time, all Incidental Rights or IR Virtual Currency to which it would otherwise be entitled as of such time and with respect to which it has not taken any Affirmative Action at or prior to such time. The Sponsor has committed to cause the Trust to irrevocably abandon any Incidental Rights and IR Virtual Currency to which the Trust may become entitled in the future. There can be no complete assurance that these abandonments will be treated as effective for U.S. federal income tax purposes. If the Trust were treated as owning any asset other than SUI as of any date on which it creates or redeems Shares, it might cease to qualify as a grantor trust for U.S. federal income tax purposes.

In addition, at this time the Trust is permitted to create or redeem Shares pursuant to In-Kind Orders and Cash Orders. In general, investment vehicles intended to be treated as grantor trusts for U.S. federal income tax purposes historically have created additional trust interests only in-kind, and there is no authority directly addressing whether a grantor trust may create or redeem trust interests under procedures similar to those that govern Cash Orders. Accordingly, there can be no complete assurance that the creation or redemption of Shares under the procedures governing Cash Orders will not cause the Trust to fail to qualify as a grantor trust for U.S. federal income tax purposes.

income would be considered to be “effectively connected” with the conduct of a trade or business in the United States and, accordingly, a non-U.S. person owning Shares could be subject to U.S. federal income tax on a net income basis with respect to that “effectively connected” income and be required to file a U.S. tax return. If none of the Trust’s Staking income were considered to be “effectively connected” income, a non-U.S. person owning Shares might be subject to withholding on its pro rata portion of income from the Trust’s Staking activities as described below in “—Shareholders may be subject to withholding tax on Staking Consideration received as staking rewards and income derived from forks, airdrops and similar occurrences.” Tax-exempt shareholders may also recognize “unrelated business taxable income” (“UBTI”) from the Trust’s Staking activities if the Trust is not treated as a corporation for U.S. federal income tax purposes.

The treatment of digital assets for U.S. federal income tax purposes is uncertain.

As discussed in the section entitled “Material U.S. Federal Income Tax Consequences—Uncertainty Regarding the U.S. Federal Income Tax Treatment of Digital Assets,” assuming that the Trust is properly treated as a grantor trust for U.S. federal income tax purposes, each beneficial owner of Shares will be treated for U.S. federal income tax purposes as the owner of an undivided interest in the SUI (and, if applicable, any Incidental Rights, IR Virtual Currency and/or any Staking Consideration) held in the Trust. Due to the new and evolving nature of digital assets and the absence of comprehensive guidance with respect to digital assets, many significant aspects of the U.S. federal income tax treatment of digital assets are uncertain.

In 2014, the IRS released a notice (the “Notice”) discussing certain aspects of “convertible virtual currency” (that is, digital assets that have an equivalent value in fiat currency or that act as substitutes for fiat currency) for U.S. federal income tax purposes and, in particular, stating that such digital assets (i) are “property” (ii) are not “currency” for purposes of the rules relating to foreign currency gain or loss and (iii) may be held as a capital asset. In 2019, the IRS released a revenue ruling and a set of “Frequently Asked Questions” that has been updated from time to time since (the “Ruling & FAQs”). The Ruling & FAQs provide some additional guidance, including guidance to the effect that, under certain circumstances, hard forks of digital assets are taxable events giving rise to ordinary income and guidance with respect to the determination of the tax basis of digital assets. Moreover, in 2023, the IRS released a revenue ruling that provided guidance on digital asset staking, including guidance to the effect that staking rewards will, under certain circumstances, be treated as giving rise to taxable income (the “2023 Staking Guidance”). Further, the IRS recently issued the 2025 Revenue Procedure, which provides a staking safe harbor for certain grantor trust vehicles. However, the Notice, the Ruling & FAQs, the 2023 Staking Guidance and the 2025 Revenue Procedure do not address other significant aspects of the U.S. federal income tax treatment of digital assets. For example, for a non-U.S. Holder (as defined below), there currently is no guidance directly addressing whether or in what circumstances engaging in certain activities to generate yield on digital assets, including Staking, could give rise to income that is effectively connected with a trade or business in the United States. Similarly, for a U.S. tax-exempt shareholder, there currently is no guidance directly addressing whether or in what circumstances such activities could give rise to UBTI. Moreover, although the Ruling & FAQs address the treatment of hard forks, there continues to be uncertainty with respect to the timing and amount of the income inclusions. While the Ruling & FAQs do not address most situations in which airdrops occur, it is clear from the reasoning of the Ruling & FAQs that the IRS generally would treat an airdrop as a taxable event giving rise to ordinary income.

There can be no assurance that the IRS will not alter its position with respect to digital assets in the future or that a court would uphold the treatment set forth in the Notice, the Ruling & FAQs, the 2023 Staking Guidance and the 2025 Revenue Procedure. It is also unclear what additional guidance on the treatment of digital assets for U.S. federal income tax purposes may be issued in the future. Any such alteration of the current IRS positions or additional guidance could result in adverse tax consequences for shareholders and could have an adverse effect on the value of SUI. Future developments that may arise with respect to digital assets may increase the uncertainty with respect to the treatment of digital assets for U.S. federal income tax purposes. For example, the Notice addresses only digital assets that are “convertible virtual currency,” and it is conceivable that, as a result of a fork, airdrop or similar occurrence, the Trust could hold certain types of digital assets that are not within the scope of the Notice, in the event the Sponsor seeks to change the Trust’s policy with respect to Incidental Rights or IR Virtual Currency, subject to NYSE Arca obtaining regulatory approval from the SEC.

Shareholders are urged to consult their tax advisers regarding the tax consequences of owning and disposing of Shares and digital assets in general.

Future developments regarding the treatment of digital assets for U.S. federal income tax purposes could adversely affect the value of the Shares.

As discussed above, many significant aspects of the U.S. federal income tax treatment of digital assets, such as SUI, are uncertain, and it is unclear what guidance on the treatment of digital assets for U.S. federal income tax purposes may be issued in the future. It is possible that any such guidance would have an adverse effect on the prices of digital assets, including on the price of SUI in the Digital Asset Markets, and therefore may have an adverse effect on the value of the Shares.

Because of the evolving nature of digital assets, it is not possible to predict potential future developments that may arise with respect to digital assets, including forks, airdrops and similar occurrences. Such developments may increase the uncertainty with respect to the treatment of digital assets for U.S. federal income tax purposes. Moreover, certain future developments could render it impossible, or impracticable, for the Trust to continue to be treated as a grantor trust for U.S. federal income tax purposes.

Future developments in the treatment of digital assets for tax purposes other than U.S. federal income tax purposes could adversely affect the value of the Shares.

The taxing authorities of certain states, including New York, (i) have announced that they will follow the Notice with respect to the treatment of digital assets for state income tax purposes and/or (ii) have issued guidance exempting the purchase and/or sale of digital assets for fiat currency from state sales tax. However, it is unclear what further guidance on the treatment of digital assets for state tax purposes may be issued in the future.

The treatment of digital assets for tax purposes by non-U.S. jurisdictions may differ from the treatment of digital assets for U.S. federal, state or local tax purposes. It is possible, for example, that a non-U.S. jurisdiction would impose sales tax or value-added tax on purchases and sales of digital assets for fiat currency. If a foreign jurisdiction with a significant share of the market of Sui Network users imposes onerous tax burdens on digital asset users, or imposes sales or value-added tax on purchases and sales of digital assets for fiat currency, such actions could result in decreased demand for SUI in such jurisdiction.

Any future guidance on the treatment of digital assets for state, local or non-U.S. tax purposes could increase the expenses of the Trust and could have an adverse effect on the prices of digital assets, including on the price of SUI in the Digital Asset Markets. As a result, any such future guidance could have an adverse effect on the value of the Shares.

The tax treatment of SUI and transactions involving SUI for state and local tax purposes is not settled.

Because SUI is a new technological innovation, the tax treatment of SUI for state and local tax purposes, including, without limitation state and local income and sales and use taxes, is not settled. It is uncertain what guidance, if any, on the treatment of SUI for state and local tax purposes may be issued in the future. A state or local government authority’s treatment of SUI may have negative consequences, including the imposition of a greater tax burden on investors in SUI or the imposition of a greater cost on the acquisition and disposition of SUI generally. Any such treatment may have a negative effect on prices of SUI and may adversely affect the value of the Shares.

A U.S. tax-exempt shareholder may recognize “unrelated business taxable income” as a consequence of an investment in Shares.

Under the guidance provided in the Ruling & FAQs, hard forks, airdrops and similar occurrences with respect to digital assets will under certain circumstances be treated as taxable events giving rise to ordinary income. Moreover, as separately provided by the IRS in the 2023 Staking Guidance, staking rewards will, under certain circumstances, be treated as giving rise to taxable income. In the absence of guidance to the contrary, it is possible that any such income recognized by a U.S. tax-exempt shareholder would constitute UBTI. A tax-exempt shareholder should consult its tax adviser regarding whether such shareholder may recognize UBTI as a consequence of an investment in Shares. See “Material U.S. Federal Income Tax Consequences.”

Shareholders may be subject to withholding tax on Staking Consideration received as staking rewards and income derived from forks, airdrops and similar occurrences.

The Ruling & FAQs do not address whether income recognized by a non-U.S. person as a result of a fork, airdrop or similar occurrence or staking could be subject to the 30% withholding tax imposed on U.S.-source “fixed or determinable annual or periodical” income. Based on the current manner in which the Trust’s Staking activities are undertaken and certain assurances from the Trust’s Staking Providers regarding their connections to the United States, the Trust believes that its income from staking rewards should not be treated as U.S.-source FDAP income. However, that conclusion is not free from doubt under current law due to the lack of direct governing authority, and no assurance can be given that a withholding agent (including a broker through which Shares are held) will not take a contrary position. In addition, changes in law or changes to the Trust’s Staking Arrangements could cause all or a portion of the Trust’s staking rewards to be treated as U.S.-source FDAP income in the future. As a result, Non-U.S. Holders (as defined under “Material U.S. Federal Income Tax Consequences—Tax Consequences to Non-U.S. Holders”) should be aware that, in the absence of guidance, a withholding agent (including a broker through which a Non-U.S. Holder holds Shares) may withhold 30% of any such income recognized by a non-U.S. Holder in respect of its Shares, including by deducting such withheld amounts from proceeds that

such non-U.S. Holder would otherwise be entitled to receive in connection with a distribution of Incidental Rights, IR Virtual Currency or Staking Consideration received as staking rewards. See “Material U.S. Federal Income Tax Consequences.”

In addition, the Trust may enter into Staking Arrangements with Staking Providers organized in, or that have operations in, a non-U.S. jurisdiction. Non-U.S. jurisdictions may seek to impose withholding tax on Staking Consideration received by the Trust as staking rewards, which may negatively affect a shareholder’s investment in the Trust.

Risk Factors Related to Potential Conflicts of Interest

Potential conflicts of interest may arise among the Sponsor or its affiliates and the Trust. The Sponsor and its affiliates have no fiduciary duties to the Trust and its shareholders other than as provided in the Trust Agreement, which may permit them to favor their own interests to the detriment of the Trust and its shareholders.

The Sponsor will manage the affairs of the Trust. Conflicts of interest may arise among the Sponsor and its affiliates, on the one hand, and the Trust and its shareholders, on the other hand. As a result of these conflicts, the Sponsor may favor its own interests and the interests of its affiliates over the Trust and its shareholders. These potential conflicts include, among others, the following:

•

The Sponsor has no fiduciary duties to, and is allowed to take into account the interests of parties other than, the Trust and its shareholders in resolving conflicts of interest, provided the Sponsor does not act in bad faith;

•

The Trust has agreed to indemnify the Sponsor and its affiliates pursuant to the Trust Agreement;

•

The Sponsor is responsible for allocating its own limited resources among different clients and potential future business ventures, to each of which it owes fiduciary duties;

•

The Sponsor and its staff also service affiliates of the Sponsor, including several other digital asset investment vehicles, and their respective clients and cannot devote all of its, or their, respective time or resources to the management of the affairs of the Trust;

•

The Sponsor, its affiliates and their respective officers and employees are not prohibited from engaging in other businesses or activities, including those that might be in direct competition with the Trust;

•

Affiliates of the Sponsor have substantial direct investments in SUI that they are permitted to manage taking into account their own interests without regard to the interests of the Trust or its shareholders, and any increases, decreases or other changes in such investments could affect the Index Price and, in turn, the value of the Shares;

•

There is an absence of arm’s-length negotiation with respect to certain terms of the Trust, and, where applicable, there has been no independent due diligence conducted with respect to the Trust;

•

The Sponsor’s indirect parent company, DCG, holds 1.45% of the Shares representing ownership in the Trust, as of March 19, 2026;

•

Several employees of the Sponsor and the Sponsor’s indirect parent company, DCG, are FINRA-registered representatives who historically maintained their licenses through Genesis and currently maintain their licenses through Grayscale Securities;

•

DCG is (i) the indirect parent company of the Sponsor; (ii) the indirect parent company of Grayscale Securities, the Authorized Participant from August 1, 2024 (the commencement of the Trust’s operations) through February 17, 2026; and (iii) a minority interest holder in Kraken, one of the Digital Asset Trading Platforms included in the Index, representing less than 1.0% of its equity;

•

DCG has investments in a large number of digital assets and companies involved in the digital asset ecosystem, including trading platforms and custodians. DCG’s positions on changes that should be adopted in the Sui Network could be adverse to positions that would benefit the Trust or its shareholders. Additionally, before or after a hard fork on the Sui Network, DCG’s position regarding which fork among a group of incompatible forks of the Sui Network should be considered the “true” Sui Network could be adverse to positions that would most benefit the Trust;

•

DCG has been vocal in the past about its support for digital assets other than SUI. Any investments in, or public positions taken on, digital assets other than SUI by DCG could have an adverse impact on the price of SUI;

•

The Sponsor decides whether to retain separate counsel, accountants or others to perform services for the Trust;

•

While the Index Provider does not currently utilize data from over-the-counter markets or derivatives platforms, it may decide to include pricing from such markets or platforms in the future;

•

The Sponsor may appoint an agent to act on behalf of the shareholders, and such agent may be the Sponsor or an affiliate of the Sponsor; and

•

The Sponsor has historically, and may again select an Index Provider that is an affiliate of the Sponsor and the Trust.

By purchasing the Shares, shareholders agree and consent to the provisions set forth in the Trust Agreement. See “Item 1. Business—Description of the Trust Agreement.”

For a further discussion of the conflicts of interest among the Sponsor, the distributor, the marketer, Authorized Participant, Liquidity Providers, the Trust and others, see “Item 13. Certain Relationships and Related Transactions and Director Independence.”

DCG is a minority interest holder in Kraken, which operates one of the Digital Asset Trading Platforms included in the Index Price.

DCG, the indirect parent company of the Sponsor, holds a minority interest of less than 1.0% in Kraken. The Sponsor values its digital assets by reference to the Index Price. The Index Price is the price in U.S. dollars of a SUI derived from the Digital Asset Trading Platforms that are reflected in the Index developed by CoinDesk Indices, Inc. as of 4:00 p.m., New York time on each business day. Kraken is one of the Digital Asset Trading Platforms included in the Index.

Although DCG does not exercise control over Kraken, it is possible that investors could have concerns that DCG could influence market data provided by this Digital Asset Trading Platform in a way that benefits DCG, for example by artificially inflating the values of SUI in order to increase the Sponsor’s fees. This could make the Trust’s Shares less attractive to investors than the shares of similar vehicles that do not present these concerns, adversely affect investor sentiment about the Trust and negatively affect Share trading prices.

Shareholders cannot be assured of the Sponsor’s continued services, the discontinuance of which may be detrimental to the Trust.

Shareholders cannot be assured that the Sponsor will be willing or able to continue to serve as sponsor to the Trust for any length of time. If the Sponsor discontinues its activities on behalf of the Trust and a substitute sponsor is not appointed, the Trust will terminate and liquidate its SUI.

Appointment of a substitute sponsor will not guarantee the Trust’s continued operation, successful or otherwise. Because a substitute sponsor may have no experience managing a digital asset financial vehicle, a substitute sponsor may not have the experience, knowledge or expertise required to ensure that the Trust will operate successfully or continue to operate at all. Therefore, the appointment of a substitute sponsor may not necessarily be beneficial to the Trust and the Trust may terminate. See “Item 13. Certain Relationships and Related Transactions and Director Independence—The Sponsor.”

Although the Custodian is a fiduciary with respect to the Trust’s assets, if the Custodian resigns or is removed by the Sponsor or otherwise, without replacement, it would trigger early termination of the Trust.

The Custodian is a fiduciary under § 100 of the New York Banking Law and a qualified custodian for purposes of Rule 206(4)-2(d)(6) under the Investment Advisers Act and is licensed to custody the Trust’s SUI in trust on the Trust’s behalf. However, the SEC previously released proposed amendments in February 2023 to Rule 206(4)-2 that, if enacted as proposed, would amend the definition of a “qualified custodian” under Rule 206(4)-2(d)(6). Executive officers of the Custodian’s parent company have made public statements indicating that the Custodian will remain a qualified custodian under the proposed SEC rule, if enacted as proposed. In June 2025, however, the SEC formally withdrew that proposed rulemaking and stated that it does not intend to issue final rules based on the proposal. However, there can be no assurance that the Custodian would continue to qualify as a “qualified custodian” under a final rule that may be proposed or adopted by the SEC in the future.

Furthermore, during the initial term, the Custodian may terminate the Prime Broker Agreement for Cause (as defined in “Description of the Prime Broker Agreement—Termination”) at any time, and after the initial term, the Custodian can terminate the Agreement for any reason upon the notice period provided under the Prime Broker Agreement. If the Custodian resigns or is removed by the Sponsor or otherwise, without replacement, the Trust will dissolve in accordance with the terms of the Trust Agreement.

Shareholders may be adversely affected by the lack of independent advisers representing investors in the Trust.

The Sponsor has consulted with counsel, accountants and other advisers regarding the formation and operation of the Trust. No counsel was appointed to represent investors in connection with the formation of the Trust or the establishment of the terms of the Trust Agreement and the Shares. Moreover, no counsel has been appointed to represent an investor in connection with the offering of the Shares. Accordingly, an investor should consult his, her or its own legal, tax and financial advisers regarding the desirability of the value of the Shares. Lack of such consultation may lead to an undesirable investment decision with respect to investment in the Shares.

The Trust is an “emerging growth company” and the reduced disclosure requirements applicable to emerging growth companies may make the Shares less attractive to investors.

The Trust is an “emerging growth company,” as defined in the JOBS Act, and intends to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies, including, but not limited to, not being required to

comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and exemptions from the requirement of shareholder approval of any golden parachute payments not previously approved. The Trust intends to take advantage of these reporting exemptions until it is no longer an emerging growth company. The Sponsor and the Trust cannot predict if investors will find the Shares less attractive because the Trust will rely on these exemptions. The Trust will remain an emerging growth company for up to five years after its initial public offering, although it will lose that status sooner if the Trust has more than $1.235 billion of revenues in a fiscal year, has more than $700 million in market value of Shares held by non-affiliates as of any June 30 or issues more than $1.0 billion of non-convertible debt over a rolling three-year period. If some investors find the Shares less attractive as a result, there may be a less active trading market for the Shares and the price of the Shares may be more volatile.

Risk Factors Related to Staking

Although the Trust is permitted to engage in Staking, the Trust will not be permitted to engage in any different form of Staking unless (and, then, only to the extent that) the Staking Condition is satisfied in addition to the Trust satisfying any additional requirements that may arise in connection with the satisfaction of the Staking Condition, which could negatively affect the value of the Shares.

Although the Trust is permitted to engage in Staking, the Trust is only permitted to engage in Staking to the extent that the Staking Condition is satisfied with respect thereto. There can be no assurance that the Trust will be permitted to engage in any different form of Staking in the future. The Trust Agreement provides that the Trust may engage in Staking, but only if (and, then, only to the extent that) the Staking Condition has been satisfied.

Subject to the Staking Condition being satisfied and subject to compliance with certain related requirements, in the future the Sponsor may, from time to time, seek to modify the form of Staking in which the Trust engages, but only if (and, then, only to the extent that) the Staking Condition has been satisfied with respect to any such modified form of Staking, and subject to compliance with any additional requirements that may arise in connection with satisfaction of the Staking Condition with respect thereto. However, as long as the Staking Condition and any related requirements have not been satisfied with respect to any modified form of Staking, the Trust will not be permitted to engage in such modified form of Staking, which could place the Shares at a comparative disadvantage relative to an investment in SUI directly or through a vehicle that is not subject to such a prohibition, which could negatively affect the value of the Shares.

Staking introduces a risk of loss of SUI, which could adversely affect the value of the Shares.

Staking introduces a risk of loss of SUI. None of the Trust’s assets, including potentially staked assets, are subject to the protections enjoyed by depositors or customers of institutions with FDIC or Securities Investor Protection Corporation membership.

The Sui Network may impose penalties (i.e., “slashing”) if a validator commits malicious acts related to the validation of blocks with invalid transactions. Although the Sui Network does not implement slashing of staked principal, the protocol may impose penalties—such as loss of rewards or removal from the validator set—if a validator commits malicious acts or fails to perform required validation activities.

There can be no guarantee that slashing penalties and resulting losses will not occur as a result of the activities of a Staking Provider. Furthermore, a Staking Provider’s liability to the Trust is expected to be limited, and a Staking Provider may lack the assets or insurance in order to support the recovery of any losses incurred. While the Staking Arrangements may provide for indemnification up to a specified cap, slashing insurance or other reimbursement programs, there can be no guarantee that the Trust would recover any of its staked assets, or the value thereof, if it is subject to penalties imposed by the Sui Network.

Staked SUI tokens will be inaccessible for a variable period of time, determined by a range of factors, which could result in certain liquidity risk to the Trust.

Under current Sui Network protocols, staked SUI tokens are permitted to be un-staked by the holder of the private keys for the withdrawal address of such SUI tokens. However, as part of the “activating” and “exiting” processes of staking, staked SUI tokens will be inaccessible for a variable period of time determined by a range of factors, including network congestion, resulting in certain liquidity risks that the Sponsor plans to manage. “Activation” is the funding of a validator to be included in the active set, thereby allowing the validator to participate in the Sui Network’s proof-of-stake consensus protocol. “Exit” is the request to exit from the active set and no longer participate in the Sui Network’s proof-of-stake consensus protocol. As part of these “activating” and “exiting” processes of staking on the Sui Network, any staked SUI will be inaccessible for a period of time. The duration of activating and exiting periods are dependent on a range of factors, including network conditions. However, depending on demand, un-staking can take between hours, days or weeks to complete. This can result in certain liquidity risk to the Trust, which the Sponsor will seek to manage through a range of risk management methods.

The Sponsor anticipates that it will engage in staking with respect to all of the Trust’s SUI at all times, except (i) as necessary to pay the Sponsor’s Fee and the Sponsor’s Staking Fee, (ii) as necessary to pay any additional Trust expenses, (iii) as necessary to satisfy existing and reasonably foreseen potential redemption requests (assuming the Trust is then permitted to operate an ongoing redemption program) as determined by the Sponsor, (iv) as necessary to reduce the SUI obtained by the Trust as Staking Consideration to cash for distribution at regular intervals, (v) as necessary to reduce the SUI obtained by the Trust as Native Staking Consideration to cash in connection with the Trust's liquidation, (vi) as necessary to take protective actions in respect of vulnerabilities in the source code or cryptography underlying the Sui Network and/or its proof-of-stake protocol, its staking smart contracts or its validator client software, (vii) if the Custodian discontinues its arrangements with the Trust and such discontinuance affects the Trust's SUI, for so long as is reasonably necessary to re-establish those arrangements or to establish similar arrangements with other parties, (viii) if the Custodian discontinues its arrangements with the Staking Provider and such discontinuance affects the Trust's SUI, for so long as is reasonably necessary to re-establish those arrangements or to establish similar arrangements with other parties, (ix) in the event of a change in applicable law or regulation, (x) as necessary to maintain a Liquidity Sleeve (as defined herein), (xi) as necessary pursuant to a “contingent liquidity arrangement” within the meaning of Section 6.02(12) of IRS Revenue Procedure 2025-31 or (xii) in accordance with any other exception that is expressly contemplated by an opinion, ruling or tax guidance that satisfies the Staking Condition. All SUI received by the Trust in connection with the creation of new Shares, or as Staking Consideration, would also be staked upon receipt by the Trust, unless one or more of the exceptions described in clauses (i)-(xii) above applies. Under the Trust Agreement, the Trust's Staking Arrangements also must satisfy certain other requirements derived from IRS Revenue Procedure 2025-31.

As of the date of this filing, and subject to the satisfaction of the Staking Condition, the Sponsor generally seeks to stake as much of the Trust’s SUI as is practicable (i.e., up to 100%) at all times, with the remainder of the Trust’s SUI remaining unstaked in order to address the various exceptions and other considerations described herein. The percentage of the Trust’s SUI that is staked each day is reported the following day at 4:00 p.m., New York time, on etfs.grayscale.com/gsui.

In the future and subject to the satisfaction of the Staking Condition thereto, the Sponsor, on behalf of the Trust, may be able to enter into short-term financing arrangements or implement other mechanisms to manage SUI liquidity constraints. For example, in the future, the Sponsor may arrange for the Trust to enter into redemption orders involving the delivery of SUI to a Liquidity Provider on a delayed basis (i.e., when the appropriate number of the Trust’s SUI are or become freely transferable), after the Liquidity Provider has delivered cash to the Trust to settle the redemption order. Under a delayed delivery order, the Variable Fee payable by an Authorized Participant would be adjusted, based on the estimated length of time to SUI delivery, to compensate the Liquidity Provider for agreeing to accept settlement on a delayed basis. No further adjustment to the Variable Fee would be made, and the Trust would not be required to further compensate the Liquidity Provider (or be entitled to compensation from the Liquidity Provider) if the actual date of SUI delivery differed from the estimated delivery date. It is also possible that, in connection with future redemption orders, the Sponsor may make arrangements for the Trust to obtain liquid SUI from the Custodian or another institutional liquidity provider in exchange for the Trust’s present or future delivery of a similar number of SUI tokens, although the details of any such future arrangement are not presently known. These and other liquidity risk policies and procedures are intended to be consistent with NYSE Arca's generic listing standards as well as recent IRS guidance. However, there can be no assurance that such arrangements will be available as intended or provide sufficient liquidity to satisfy redemption requests.

Due to the time involved in “exiting” the staking process, there is a risk that the Trust could become unable to timely meet excessive redemption requests in amounts that are greater than the portion of the Trust’s SUI that remains un-staked, leading to temporary delays in settlement and, in extreme scenarios, the temporary unavailability of the Trust’s redemption program. Moreover, any staked SUI which must be un-staked in order to fulfill a redemption (to the extent such redemption cannot be fulfilled utilizing the portion of the Trust’s SUI that has not been staked, or through another mechanism to manage liquidity in connection with Redemption Orders contemplated by an opinion of a Tax Advisor, a Tax Ruling or Tax Guidance that satisfies the Staking Condition) will be un-staked only after the redemption request is approved by the Trust, the Sponsor executes an un-stake or withdrawal transaction through the Custodian, and such transaction is processed by the Sui Network. The Staking Provider will not be able to transfer unstaked SUI or Staking Consideration to another address on the Sui Network.

Although the Sponsor anticipates, if the Staking Condition has been satisfied with respect to such activities, that the Trust may enter into financing arrangements in order to fulfill redemption requests if the Trust’s unstaked SUI is insufficient to do so, there can be no assurance that such arrangements will be available as intended or provide sufficient liquidity to satisfy redemption requests.

The Trust will be dependent on third parties or intermediary technical systems to effectively execute the Trust’s Staking Arrangements.

Staking is carried out by the third-party Staking Providers, the amount of Staking Consideration that the Trust’s staking activity generates is dependent on the performance of the Staking Provider, including the adequacy and reliability of the hardware and software utilized by the Staking Provider. If the Custodian or the Staking Provider experience service outages or otherwise are unable to optimally execute the Staking of the Trust’s SUI, the Trust’s Staking Consideration may be adversely affected. Moreover, the Trust’s Staking Arrangements may rely on smart contracts, wallet infrastructure, validator clients, or other intermediary technical systems that could malfunction, contain vulnerabilities, or be subject to cyberattacks, any of which could result in loss or inaccessibility of SUI.

The regulatory landscape surrounding Staking is uncertain.

The regulatory landscape surrounding Staking is highly uncertain, and may expose the Sponsor, Custodian, third-party Staking Providers and the Trust and its shareholders to unforeseen regulatory risks or potential enforcement actions. For example, there is a risk that the Staking Arrangements could constitute an “investment contract” under the federal securities laws, such that it is a security, and thus needs to be registered or eligible for an exemption from registration. In May 2025, staff at the SEC Division of Corporation Finance issued a statement (the “SEC Staking Statement”) expressing the view that certain staking activities do not involve the offer and sale of securities within the meaning of the federal securities laws, and we believe the Staking Arrangements satisfy the criteria in this guidance. However, the SEC Staking Statement is not a rule, regulation, guidance, or statement of the SEC, and has no legal force or effect. There is accordingly a risk that a court could disagree with the views expressed in the SEC Staking Statement. In that case, or if SUI were deemed a security, there would also be a risk that a Staking Provider could be deemed to be acting as a broker-dealer, on the basis that the Staking Provider is receiving a commission for effecting the staking transactions and receipt of Staking Consideration.

The Sponsor is permitted to cause the Trust to engage in Staking only if certain conditions set forth in the Trust Agreement relating to the qualification of the Trust as a grantor trust for U.S. federal income tax purposes are satisfied. Due to the lack of authority regarding the ability of a grantor trust to engage in activities such as Staking, there can be no assurance whether or when these conditions will be satisfied or the Trust will be permitted to engage in Staking.

Beneficial owners of Shares could incur tax liabilities without receiving corresponding distributions from the Trust.

As of the date of this filing, the Staking Condition has been satisfied as to the particular form of Staking described in this Annual Report. Shareholders may suffer adverse tax consequences as a result. In particular, the IRS has indicated that the receipt of Staking Consideration gives rise to current, ordinary income for U.S. federal income tax purposes. Assuming that the Trust is properly treated as a grantor trust for U.S. federal income tax purposes, beneficial owners of Shares will be required to take their ratable share of any such income into account in determining their own tax liability, regardless of whether the Trust makes any corresponding distributions. Shareholders should therefore expect that other sources of funds may be needed to satisfy any associated tax liability. Moreover, if the Trust were to sell SUI to fund cash distributions in respect of that tax liability, a shareholder generally would be treated as having sold its pro rata share of those SUI for their fair market value at that time (which, in the case of SUI sold by the Trust, generally will be equal to the cash proceeds received by the Trust in respect thereof), and the shareholders generally would recognize gain or loss on such sale as described in the section entitled “Item 1. Business—Material U.S. Federal Income Tax Consequences.”

Item 1B. Unresolved Staff Comments

Not applicable.

Item 1C. Cybersecurity

To prevent, detect and respond to information security threats, the Sponsor maintains a cyber risk management program. The program is supervised by an in-house dedicated Chief Information Security Officer (“CISO”), with over 15 years of experience in financial services risk management, whose team is responsible for leading enterprise-wide cybersecurity strategy, policy, standards, architecture, and processes. The Enterprise Risk Committee (“ERC”), which includes members of management of the Sponsor, receives regular reports from the CISO on, among other things, the Sponsor’s cyber risks and threats, the status of projects to strengthen the Sponsor’s information security systems, assessments of the Sponsor’s security program and the emerging threat landscape.

The ERC provides updates to the Board quarterly, including on changes to security risks and outcomes. The CISO also promptly informs and updates the ERC and the Board of the Sponsor about any information security incidents that may pose a material risk to the Sponsor. The Sponsor contracts an independent third party to conduct a full cyber risk assessment annually, and the results of those assessments are included in reporting to the ERC and the Board. Material outcomes from any penetration testing, vulnerability scanning, and business continuity or disaster recovery testing are additionally included in reporting to the ERC and Board.

The Sponsor’s Security Awareness Program includes training that reinforces the Sponsor’s Information Security policies, standards, and practices, and the expectation that employees will comply with these policies. The Security Awareness Program engages personnel through training on how to identify potential cybersecurity risks and protect the Sponsor’s resources and information. This training is mandatory for all employees upon onboarding at the firm and again annually, and it is supplemented by firmwide training and testing initiatives, including periodic phishing tests.

The Sponsor administers a Third-Party Risk Management Program at the firm to identify, assess and oversee the risk associated with service providers and third parties involved in the supply chain. Third parties are assessed for risk and may additionally be required to adhere to additional security diligence requirements administered with oversight from the CISO according to risk, including cybersecurity diligence questionnaires, evidence validation, SOC report reviews, and/or on-site assessments. Material changes to the program, new, or worsening security risks associated with third parties are reported to the ERC at least quarterly.

Cybersecurity Breaches:

During the year ended December 31, 2025, we did not identify any cybersecurity threats at the Sponsor or the Trust that have materially affected or are reasonably likely to materially affect our business strategy, results of operations, or financial condition. However, even though we take steps to employ reasonable cybersecurity efforts, not every cybersecurity incident can be prevented or detected. Therefore, while we believe there are currently no risks from any potential cybersecurity threat or cybersecurity incident that are reasonably likely to have a material effect on our results of operations or financial condition, the likelihood or severity of such risks are difficult to predict.

Item 2. Properties

None.

Item 3. Legal Proceedings

Grayscale Operating, LLC, the former Co-Sponsor of the Trust until May 3, 2025, was a party to certain legal proceedings during the period covered by this report. Although the Trust is not a party to these proceedings, the Trust may in the future be subject to legal proceedings or disputes.

On May 19, 2025, Genesis Global Capital, LLC (“Genesis Capital”) and Genesis Asia Pacific Pte. Ltd. (“Genesis Asia”) filed a complaint in the United States Bankruptcy Court for the Southern District of New York (“SDNY Bankruptcy Court”) against Digital Currency Group, Inc. (“DCG”) and certain of its affiliates including GSO alleging that Genesis Capital made certain preferential transfers to GSI, the predecessor in interest to GSO prior to the Merger, during the preference period prior to Genesis Capital’s filing of a bankruptcy petition in SDNY Bankruptcy Court while GSI was allegedly an insider to Genesis Capital pursuant to 11 U.S.C. § 101(31). Genesis Capital seeks to avoid the alleged preferential transfers pursuant to 11 U.S.C. § 547(b), as well as recovery of property and disallowance of claims. Genesis Capital is seeking to avoid transfers to GSI, the predecessor in interest to GSO prior to the Merger, of 105 Bitcoin and 37,647.06 Ethereum Classic tokens. GSO believes this lawsuit is without merit and intends to vigorously defend against it.

As of the date of this Annual Report, the Sponsor does not expect the foregoing proceedings to have a material adverse effect on the Trust’s business, financial condition or results of operations.

The Sponsor and/or the Trust may be subject to additional legal proceedings and disputes in the future.

Item 4. Mine Safety Disclosures

Not applicable.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Market Information

From August 1, 2024 (the commencement of the Trust’s operations) to February 17, 2026, Grayscale Securities was the only acting Authorized Participant of the Trust. On or after February 17, 2026, the Sponsor, on behalf of the Trust, and the Transfer Agent entered into Participant Agreements with a number of unaffiliated Authorized Participants in connection with the listing and trading of the Shares of NYSE Arca. As of the date of this Annual Report, Jane Street Capital, LLC and Virtu Americas LLC have agreed to act as Authorized Participants. The Shares commenced trading on NYSE Arca on February 18, 2026 under the ticker symbol “GSUI.”

Holders of Record

As of December 31, 2025, there were approximately 28 DTC participating shareholders of record of the Trust. Because most of the Trust’s Shares are held by brokers and other institutions on behalf of shareholders, we are unable to estimate the total number of shareholders represented by these record holders.

Dividends

The Trust made no distributions to shareholders during the year ended December 31, 2025 and the period from August 1, 2024 (the commencement of the Trust’s operations) to December 31, 2024. The Trust has no obligation to make periodic distributions to shareholders.

Recent Sales of Unregistered Shares

As of December 31, 2025, the Registrant had distributed 212,900 Shares at varying prices determined by reference to the NAV per Share to selected “accredited investors,” within the meaning of Rule 501 of Regulation D under the Securities Act. The Shares were sold in connection with an ongoing offering pursuant to Rule 506(c) of Regulation D under the Securities Act. Grayscale Securities acted as the Authorized Participant with respect to these distributions. In exchange for these sales, the Trust received an aggregate of 3,175,980.67301941 SUI. Because Shares have been, and continue to be, created and issued on a periodic basis, a “distribution,” as such term is used in the Securities Act, may be occurring from time to time. As a result, an Authorized Participant facilitating the creation of Shares and acting as a distributor and marketer during any such period may be deemed an “underwriter” under Section 2(a)(11) of the Securities Act. No underwriting discounts or commissions were paid to an Authorized Participant with respect to such sales.

Item 6. [Reserved]

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read together with, and is qualified in its entirety by reference to, our audited financial statements and related notes included elsewhere in this Annual Report, which have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). The following discussion may contain forward-looking statements based on assumptions we believe to be reasonable. Our actual results could differ materially from those discussed in these forward-looking statements. Factors that could cause or contribute to these differences include, but are not limited to, those discussed below and elsewhere in this Annual Report, particularly in “Item 1A. Risk Factors” and “Forward-Looking Statements.”

Trust Overview

The Trust is a passive entity that is managed and administered by the Sponsor and does not have any officers, directors or employees. As of December 31, 2025, the Trust holds SUI and, from time to time on a periodic basis, issues Creation Baskets in exchange for deposits of SUI. On February 17, 2026, in connection with the effectiveness of the registration statement on Form S-1 (File No. 333-291974), as amended, the Sponsor authorized the commencement of a redemption program. Shares of the Trust began trading on NYSE Arca on February 18, 2026, following the effectiveness of the Trust’s registration statement on Form S-1, as amended. The Trust issues Shares only in one or more blocks of 10,000 Shares (a block of 10,000 Shares is called a “Basket”) to certain Authorized Participants from time to time. Baskets are offered in exchange for SUI. Through its redemption program, the Trust redeems Shares from Authorized Participants on an ongoing basis. As a passive investment vehicle, the Trust’s investment objective is for the value of the Shares (based on SUI per Share) to reflect the value of the SUI held by the Trust, determined by reference to the Index Price, less the Trust’s expenses and other liabilities. While an investment in the Shares is not a direct investment in SUI, the Shares are designed to provide investors with a cost-effective and convenient way to gain investment exposure to SUI. The Trust is not managed like a business corporation or an active investment vehicle. The Trust will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective.

Prior to December 19, 2025, the Trust valued the SUI held by the Trust for operational purposes by reference to the CoinDesk Sui Reference Rate. As of December 19, 2025, the Index is the CoinDesk Sui Benchmark Rate (formerly known as the CoinDesk SUI CCIXber Reference Rate). As of December 19, 2025, the NAV and NAV per Share of the Trust is calculated using the Index Price based on the CoinDesk Sui Benchmark Rate. Prior to December 19, 2025, references to the “Index” in the Trust’s filings with the SEC, including this Annual Report on Form 10-K, refer to the CoinDesk Sui Reference Rate. From and after December 19, 2025, references to the “Index” in the Trust’s filings with the SEC are to the CoinDesk Sui Benchmark Rate.

Historically, and as of December 31, 2025, the Trust has not met its investment objective and, prior to their uplisting to NYSE Arca on February 18, 2026, the Shares quoted on OTCQB did not reflect the value of the SUI held by the Trust, less the Trust’s expenses and other liabilities, but instead had traded at both premiums and discounts to such value, which at times were substantial, although the Sponsor has observed that the Trust has begun to meet its investment objective more closely following the uplisting of the Shares to NYSE Arca.

Listing on NYSE Arca

Shares of the Trust began trading on NYSE Arca on February 18, 2026, under the ticker symbol “GSUI.”

Commencement of Redemption Program

In connection with the uplisting of the Shares, the Sponsor authorized the commencement of the Trust’s redemption program in reliance on Regulation M exemptive relief available to similarly situated commodity-based exchange traded products.

Critical Accounting Policies and Estimates

Investment Transactions and Revenue Recognition

The Trust considers investment transactions to be the receipt of SUI by the Trust in connection with Share creations and the delivery of SUI by the Trust in connection with Share redemptions or for payment of expenses in SUI. As of December 31, 2025, the Trust was not accepting redemption requests. However, the Sponsor of the Trust has since authorized the commencement of the Trust’s redemption program on February 18, 2026 in connection with the uplisting of the Shares to NYSE Arca. The Trust records its investment transactions on a trade date basis and changes in fair value are reflected as net change in unrealized appreciation or depreciation on investments. Realized gains and losses are calculated using the specific identification method. Realized gains and losses are recognized in connection with transactions including settling obligations for the Sponsor’s Fee in SUI.

Principal Market and Fair Value Determination

To determine which market is the Trust’s principal market (or in the absence of a principal market, the most advantageous market) for purposes of calculating the Trust’s net asset value in accordance with U.S. GAAP (“Principal Market NAV”), the Trust follows Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 820-10, Fair Value Measurement, which outlines the application of fair value accounting. ASC 820-10 determines fair value to be the price that would be received for SUI in a current sale, which assumes an orderly transaction between market participants on the measurement date. ASC 820-10 requires the Trust to assume that SUI is sold in its principal market to market participants or, in the absence of a principal market, the most advantageous market. Market participants are defined as buyers and sellers in the principal or most advantageous market that are independent, knowledgeable, and willing and able to transact.

The Trust only receives SUI in connection with a creation order from the Authorized Participant (or a Liquidity Provider) and does not itself transact on any Digital Asset Markets. Therefore, the Trust looks to market-based volume and level of activity for Digital Asset Markets. The Authorized Participant(s), or a Liquidity Provider, may transact in a Brokered Market, a Dealer Market, Principal-to-Principal Markets and Exchange Markets (referred to as “Trading Platform Markets” in this Annual Report), each as defined in the FASB ASC Master Glossary (collectively, “Digital Asset Markets”).

In determining which of the eligible Digital Asset Markets is the Trust’s principal market, the Trust reviews these criteria in the following order:

•

First, the Trust reviews a list of Digital Asset Markets that maintain practices and policies designed to comply with anti-money laundering (“AML”) and know-your-customer (“KYC”) regulations, and non-Digital Asset Trading Platform Markets that the Trust reasonably believes are operating in compliance with applicable law, including federal and state licensing requirements, based upon information and assurances provided to it by each market.

•

Second, the Trust sorts these Digital Asset Markets from high to low by market-based volume and level of activity of SUI traded on each Digital Asset Market in the trailing twelve months.

•

Third, the Trust then reviews pricing fluctuations and the degree of variances in price on Digital Asset Markets to identify any material notable variances that may impact the volume or price information of a particular Digital Asset Market.

•

Fourth, the Trust then selects a Digital Asset Market as its principal market based on the highest market-based volume, level of activity and price stability in comparison to the other Digital Asset Markets on the list. Based on information reasonably available to the Trust, Trading Platform Markets have the greatest volume and level of activity for the asset. The Trust therefore looks to accessible Trading Platform Markets as opposed to the Brokered Market, Dealer Market and Principal-to-Principal Markets to determine its principal market. As a result of the aforementioned analysis, a Trading Platform Market has been selected as the Trust’s principal market.

The Trust determines its principal market (or in the absence of a principal market the most advantageous market) annually and conducts a quarterly analysis to determine (i) if there have been recent changes to each Digital Asset Market’s trading volume and level of activity in the trailing twelve months, (ii) if any Digital Asset Markets have developed that the Trust has access to, or (iii) if recent changes to each Digital Asset Market’s price stability have occurred that would materially impact the selection of the principal market and necessitate a change in the Trust’s determination of its principal market.

The cost basis of the SUI received by the Trust in connection with a creation order is recorded by the Trust at the fair value of SUI at 4:00 p.m., New York time, on the creation date for financial reporting purposes. The cost basis recorded by the Trust may differ from proceeds collected by the Authorized Participant from the sale of the corresponding Shares to investors.

Investment Company Considerations

The Trust is an investment company for U.S. GAAP purposes and follows accounting and reporting guidance in accordance with the FASB ASC Topic 946, Financial Services—Investment Companies. The Trust uses fair value as its method of accounting for SUI in accordance with its classification as an investment company for accounting purposes. The Trust is not a registered investment company under the Investment Company Act. U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates and these differences could be material.

Review of Financial Results

Financial Highlights for the Year Ended December 31, 2025 and the Period from August 1, 2024 (the Commencement of the Trust’s Operations) to December 31, 2024

(All amounts in the following table and the subsequent paragraphs, except Share, SUI and price of SUI amounts, are in thousands)


	Year Ended December 31, 2025			August 1, 2024 (the Commencement of the Trust’s Operations) to December 31, 2024
Net realized and unrealized (loss) gain on investment in SUI	$	(8,548	)	$	4,977
Net (decrease) increase in net assets resulting from operations	$	(8,782	)	$	4,932
Net assets(1)	$	4,301		$	12,635

(1)

Net assets in the above table and subsequent paragraphs are calculated in accordance with U.S. GAAP based on the Digital Asset Market price of SUI on the Digital Asset Trading Platform that the Trust considered its principal market, as of 4:00 p.m., New York time, on the valuation date.

Net realized and unrealized loss on investment in SUI for the year ended December 31, 2025 was ($8,548), which includes a realized gain of $35 on the transfer of SUI to pay the Sponsor’s Fee and net change in unrealized appreciation/depreciation on investment in SUI of ($8,583). Net realized and unrealized loss on investment in SUI for the period was driven by SUI price depreciation from $4.17 per SUI as of December 31, 2024 to $1.40 per SUI as of December 31, 2025. Net decrease in net assets resulting from operations was ($8,782) for the year ended December 31, 2025, which consisted of the net realized and unrealized loss on investment in SUI, plus the Sponsor’s Fee of $234. Net assets decreased to $4,301 at December 31, 2025, a 66% decrease for the year. The decrease in net assets was due to the aforementioned SUI price depreciation and the withdrawal of approximately 77,400 SUI to pay the foregoing Sponsor’s Fee, partially offset by the contribution of approximately 130,001 SUI with a value of $448 to the Trust in connection with Share creations.

Net realized and unrealized gain on investment in SUI for the period from August 1, 2024 (the commencement of the Trust's operations) to December 31, 2024 was $4,977, which includes a realized gain of $22 on the transfer of SUI to pay the Sponsor’s Fee and net change in unrealized appreciation/depreciation on investment in SUI of $4,956. Net realized and unrealized gain on investment in SUI for the period was driven by SUI price appreciation from $0.69 per SUI as of August 1, 2024 to $4.17 per SUI as of December 31, 2024. Net increase in net assets resulting from operations was $4,932 for the period from August 1, 2024 (the commencement of the Trust's operations) to December 31, 2024, which consisted of the net realized and unrealized gain on investment in SUI, less the Sponsor’s Fee of $45. Net assets increased to $12,635 at December 31, 2024. The increase in net assets was due to the contribution of approximately 3,045,980 SUI with a value of $7,703 to the Trust in connection with Share creations and the aforementioned SUI price appreciation, partially offset by the withdrawal of approximately 16,103 SUI to pay the foregoing Sponsor’s Fee.

Cash Resources and Liquidity

The Trust only receives and holds cash in order to facilitate creations and redemptions pursuant to Cash Orders, and has not otherwise had or maintained a cash balance at any time since inception. When selling SUI in the Digital Asset Market to pay Additional Trust Expenses on behalf of the Trust, the Sponsor endeavors to sell the exact amount of SUI needed to pay expenses in order to minimize the Trust’s holdings of assets other than SUI. In addition, upon the consummation or deemed failure of a Cash Order to create or redeem Baskets, the Trust will promptly return any excess cash it continues to hold with respect to such Cash Order to the applicable counterparty. As a consequence, the Sponsor expects that the Trust will not record any cash flow from its operations and that its cash balance will be zero at the end of each reporting period. Furthermore, the Trust is not a party to any off-balance sheet arrangements.

Generally, the Trust does not intend to hold cash, except in connection with Cash Orders for creations or redemptions of Baskets. Cash includes non-interest bearing non-restricted cash with one institution. Cash in a bank deposit account, at times, may exceed U.S. federally insured limits. The Trust has not experienced any losses in such accounts and does not believe it is exposed to any significant credit risk on such bank deposits.

In exchange for the Sponsor’s Fee, the Sponsor has agreed to assume most of the expenses incurred by the Trust. As a result, the only ordinary expense of the Trust expected to be incurred is the Sponsor’s Fee. The Trust is not aware of any trends, demands, conditions or events that are reasonably likely to result in material changes to its liquidity needs.

Historical NAV and SUI Prices

As movements in the price of SUI will directly affect the price of the Shares, investors should understand recent movements in the price of SUI. Investors, however, should also be aware that past movements in the SUI price are not indicators of future movements. Movements may be influenced by various factors, including, but not limited to, government regulation, security breaches experienced by service providers, as well as political and economic uncertainties around the world.

Item 8. Financial Statements and Supplementary Data

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

There have been no disagreements with accountants on any matter of accounting principles or practices or financial statement disclosures during the year ended December 31, 2025.

Item 9A. Controls and Procedures

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

The Trust maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in its Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Principal Executive Officer and Principal Financial and Accounting Officer of the Sponsor, and to the audit committee of the Sponsor, as appropriate, to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of the Principal Executive Officer and the Principal Financial and Accounting Officer of the Sponsor, the Sponsor conducted an evaluation of the Trust’s disclosure controls and procedures, as defined under Exchange Act Rule 13a-15(e). Based on this evaluation, the Principal Executive Officer and the Principal Financial and Accounting Officer of the Sponsor concluded that, as of December 31, 2025, the Trust’s disclosure controls and procedures were effective.

Management’s Report on Internal Control over Financial Reporting

This annual report does not include a report of management’s assessment regarding internal control over financial reporting or an attestation report of the Trust’s registered public accounting firm due to a transition period established by rules of the SEC for newly public companies. In addition, because we are an “emerging growth company” under the JOBS Act, our independent registered public accounting firm will not be required to attest to the effectiveness of our internal control over financial reporting for so long as we are an emerging growth company.

Changes in Internal Control Over Financial Reporting

There was no change in the Trust’s internal controls over financial reporting that occurred during the Trust’s most recently completed fiscal quarter ended December 31, 2025 that has materially affected, or is reasonably likely to materially affect, these internal controls.

PART III

Item 10. Directors, Executive Officers and Corporate Governance

Management of the Sponsor

The Trust does not have any directors, officers or employees. Under the Trust Agreement, all management functions of the Trust have been delegated to and are conducted by the Sponsor, its agents and its affiliates, including without limitation, the Custodian and its agents. As officers of the Sponsor, Peter Mintzberg, the principal executive officer of the Sponsor, and Edward McGee, the principal financial and accounting officer of the Sponsor, may take certain actions and execute certain agreements and certifications for the Trust, in their capacity as the principal officers of the Sponsor.

As of and prior to December 31, 2024, GSI had a board of directors that was responsible for managing and directing the affairs of the Sponsor. From January 1, 2025 to October 22, 2025, GSO Intermediate Holdings Corporation (“GSOIH”), a Delaware corporation formed in connection with the Reorganization, which was the sole managing member of GSO and an indirect subsidiary of DCG, had a board of directors which was responsible for managing and directing the affairs of the Sponsor.

On October 22, 2025, GSOIH consummated an internal corporate reorganization (the “Management Reorganization”), pursuant to which GSOIH transferred a portion of its common membership units of GSO for Class A shares of Grayscale Investments, Inc. (“Grayscale Investments”), a Delaware corporation incorporated in connection with the Management Reorganization, and ceded its managing member rights in GSO to Grayscale Investments. As a result of the Management Reorganization, Grayscale Investments is now the sole managing member of GSO, the sole member of the Sponsor.

From and after October 22, 2025, as a result of the Management Reorganization, DCG Grayscale Holdco, LLC (“DCG Holdco”), the sole stockholder of Grayscale Investments, elected a board of directors (the “Board”) at Grayscale Investments. As a result of the Management Reorganization, the Board of Grayscale Investments is responsible for managing and directing the affairs of the Sponsor and consists of Barry Silbert, Mark Shifke, Simon Koster, Peter Mintzberg and Edward McGee, the same members as the board of directors of GSOIH prior to the Management Reorganization. Mr. Mintzberg and Mr. McGee also retain the authority granted to them as officers of the Sponsor under the limited liability company agreement of the Sponsor.

The Sponsor has an Audit Committee. The Audit Committee has the responsibility for overseeing the financial reporting process of the Trust, including the risks and controls of that process and such other oversight functions as are typically performed by an audit committee of a public company.

The Sponsor has a code of ethics (the “Code of Ethics”) that applies to its executive officers and agents. The Code of Ethics is available by writing the Sponsor at 290 Harbor Drive, 4th Floor, Stamford, Connecticut 06902 or calling the Sponsor at (212) 668-1427. The Sponsor’s Code of Ethics is intended to be a codification of the business and ethical principles that guide the Sponsor, and to deter wrongdoing, to promote honest and ethical conduct, to avoid conflicts of interest, and to foster compliance with applicable governmental laws, rules and regulations, the prompt internal reporting of violations and accountability for adherence to this code.

Prior to January 1, 2025, references to the “Sponsor” in this section refer to GSI, and thereafter refer to GSO or GSIS, as applicable. In connection with the Reorganization, the former Board of GSI was reconstituted at GSOIH and in connection with the Management Reorganization, the former board of GSOIH was reconstituted at Grayscale Investments. Prior to January 1, 2025, any references to the “Board” refer to the board of directors of Grayscale Investments, LLC, the former sponsor of the Trust. From January 1, 2025 to October 22, 2025, any references to the “Board” refer to the board of directors of GSOIH. From and after October 22, 2025, any references to the “Board” refer to the board of directors of Grayscale Investments.

Unless otherwise indicated, the address for each shareholder listed in the table above is c/o Grayscale Investments Sponsors, LLC, 290 Harbor Drive, 4th Floor, Stamford, Connecticut 06902.

Item 13. Certain Relationships and Related Transactions and Director Independence

General

The Sponsor has not established formal procedures to resolve all potential conflicts of interest. Consequently, shareholders may be dependent on the good faith of the respective parties subject to such conflicts to resolve them equitably. Although the Sponsor attempts to monitor these conflicts, it is extremely difficult, if not impossible, for the Sponsor to ensure that these conflicts do not, in fact, result in adverse consequences to the Trust.

The Sponsor presently intends to assert that shareholders have, by subscribing for Shares of the Trust, consented to the following conflicts of interest in the event of any proceeding alleging that such conflicts violated any duty owed by the Sponsor to investors.

Digital Currency Group, Inc.

DCG is (i) the indirect parent company of the Sponsor, (ii) the indirect parent company of Grayscale Securities, the Authorized Participant from August 1, 2024 (the commencement of Trust’s operations) through February 17, 2026, and (iii) a minority interest holder in Kraken, one of the Digital Asset Trading Platforms included in the Index, representing less than 1.0% of its equity.

102

group of incompatible forks of the Sui Network should be considered the “true” Sui Network could be adverse to positions that would most benefit the Trust.

The Sponsor

The Sponsor has a conflict of interest in allocating its own limited resources among, when applicable, different clients and potential future business ventures, to each of which it owes fiduciary duties. Additionally, the professional staff of the Sponsor also services other affiliates of the Trust, including several other digital asset investment vehicles, and their respective clients. Although the Sponsor and its professional staff cannot and will not devote all of its or their respective time or resources to the management of the affairs of the Trust, the Sponsor intends to devote, and to cause its professional staff to devote, sufficient time and resources to manage properly the affairs of the Trust consistent with its or their respective fiduciary duties to the Trust and others.

The Sponsor and Grayscale Securities are affiliates of each other, and the Sponsor may engage other affiliated service providers in the future. Because of the Sponsor’s affiliated status, it may be disincentivized from replacing affiliated service providers. In connection with this conflict of interest, shareholders should understand that affiliated service providers will receive fees for providing services to the Trust. Clients of the affiliated service providers may pay commissions at negotiated rates which are greater or less than the rate paid by the Trust.

The Sponsor and any affiliated service provider may, from time to time, have conflicting demands in respect of their obligations to the Trust and, in the future, to other clients. It is possible that future business ventures of the Sponsor and affiliated service providers may generate larger fees, resulting in increased payments to employees, and therefore, incentivizing the Sponsor and/or the affiliated service providers to allocate its/their limited resources accordingly to the potential detriment of the Trust.

There is an absence of arm’s length negotiation with respect to some of the terms of the Trust, and, where applicable, there has been no independent due diligence conducted with respect to the Trust. The Sponsor will, however, not retain any affiliated service providers for the Trust which the Sponsor has reason to believe would knowingly or deliberately favor any other client over the Trust.

Authorized Participants

From August 1, 2024 through February 17, 2026, Grayscale Securities, an affiliate of the Trust and the Sponsor, was the Authorized Participant. Effective February 18, 2026, the Sponsor, on behalf of the Trust, and the Transfer Agent entered into Participant Agreements with Jane Street Capital, LLC and Virtu Americas LLC, pursuant to which such entities have agreed to act as Authorized Participants. The Sponsor may engage additional Authorized Participants who are unaffiliated with the Trust in the future.

Proprietary Trading/Other Clients

Because the officers of the Sponsor may trade SUI for their own personal trading accounts (subject to certain internal trading policies and procedures) at the same time as they are managing the account of the Trust, the activities of the officers of the Sponsor, subject to their fiduciary duties, may, from time-to-time, result in their taking positions in their personal trading accounts which are opposite of the positions taken for the Trust. Records of the Sponsor’s officers’ personal trading accounts will not be available for inspection by shareholders.

Item 14. Principal Accountant Fees and Services

Fees for services performed by KPMG LLP (“KPMG”) for the year ended December 31, 2025 and the period from August 1, 2024 (the commencement of the Trust’s operations) to December 31, 2024 were:


	Year Ended December 31, 2025		August 1, 2024 (the Commencement of the Trust’s Operations) to December 31, 2024
Audit fees	$	155,000	$	67,600
Total	$	155,000	$	67,600

In the table above, in accordance with the SEC’s definitions and rules, Audit Fees are fees paid to KPMG for professional services for the audit of the Trust’s financial statements included in the annual report on Form 10-K and review of financial statements included in the quarterly reports on Form 10-Q, and for services that are normally provided by the accountants in connection with regulatory filings or engagements.

Pre-Approved Policies and Procedures

The Trust has no board of directors, and as a result, has no audit committee or pre-approval policy with respect to fees paid to its principal accounting firm. Such determinations, including for the fiscal year ended December 31, 2025, are made by the Sponsor’s Board and Audit Committee. Prior to January 1, 2025, “Board” refers to the board of directors of Grayscale Investments, LLC, the former Sponsor of the Trust. From January 1, 2025, to October 22, 2025, “Board” refers to the board of directors of GSOIH. From and after October 22, 2025, “Board” refers to the board of directors of Grayscale Investments.
