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 Quarterly 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 Operating, LLC (“GSO”), the co-sponsor of the Trust from January 1, 2025 to May 3, 2025, and Grayscale Investments Sponsors, LLC (“GSIS”), the co-sponsor of the Trust from January 1, 2025 to May 3, 2025 and the sole remaining sponsor thereafter (each of GSO and GSIS, the “Sponsor”, as the context may require, and GSO and GSIS, together, the “Co-Sponsors”), 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” of our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the Securities and Exchange Commission (the “SEC”) on March 7, 2025 (our “Annual Report”) and in “Part II, Item 1A. Risk Factors” herein. 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.

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

A glossary of industry and other defined terms is included in this Quarterly Report, beginning on page 28.

GRAYSCALE Ethereum Classic TRUST (ETC)

NOTES TO THE UNAUDITED FINANCIAL STATEMENTS

1. Organization

Grayscale Ethereum Classic Trust (ETC) (the “Trust”) is a Delaware Statutory Trust that was formed on April 18, 2017 and commenced operations on April 24, 2017. In general, the Trust holds Ether Classic (“ETC”) and, from time to time, issues common units of fractional undivided beneficial interest (“Shares”) (in minimum baskets of 100 Shares, referred to as “Baskets”) in exchange for ETC. The redemption of Shares is not currently contemplated and the Trust does not currently operate a redemption program. Subject to receipt of regulatory approval and approval by the Sponsor in its sole discretion, the Trust may in the future operate a redemption program. The Trust currently has no intention of seeking regulatory approval to operate an ongoing redemption program. The Trust’s investment objective is for the value of the Shares (based on ETC per Share) to reflect the value of the ETC held by the Trust, less the Trust’s expenses and other liabilities.

Grayscale Investments, LLC (“GSI”) was the sponsor of the Trust before January 1, 2025, Grayscale Operating, LLC (“GSO”) was the co-sponsor of the Trust from January 1, 2025 to May 3, 2025, and Grayscale Investments Sponsors, LLC (“GSIS”, or the “Sponsor”) was the co-sponsor of the Trust from January 1, 2025 to May 3, 2025 and is the sole remaining sponsor thereafter. GSI was, and each of GSO and GSIS are, a consolidated subsidiary of Digital Currency Group, Inc. (“DCG”). The Sponsor is responsible for the day-to-day administration of the Trust pursuant to the provisions of the Trust Agreement. The Sponsor is responsible for preparing and providing annual and quarterly reports on behalf of the Trust to investors and is also responsible for selecting and monitoring the Trust’s service providers. As partial consideration for the Sponsor’s services, the Trust pays the Sponsor a Sponsor’s Fee as discussed in Note 6. The Sponsor also acts as the sponsor and manager of other single-asset and diversified investment products, each of which is an affiliate of the Trust. Information related to the affiliated investment products can be found on the Sponsor’s website at www.grayscale.com/resources/regulatory-filings. Any information contained on or linked from such website is not part of nor incorporated by reference into these unaudited financial statements. Several of the affiliated investment products are also SEC reporting companies with their shares registered pursuant to Section 12(g) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In addition, the following affiliated investment products are SEC reporting companies with their shares registered pursuant to Section 12(b) of the Exchange Act: Grayscale Bitcoin Trust ETF, Grayscale Ethereum Trust ETF, Grayscale Ethereum Mini Trust ETF, Grayscale Bitcoin Mini Trust ETF, Grayscale CoinDesk Crypto 5 ETF and, as of October 29, 2025, Grayscale Solana Trust ETF.

Authorized Participants of the Trust are the only entities who may place orders to create or, if permitted, redeem Baskets. Grayscale Securities, LLC (“Grayscale Securities” or, in such capacity, an “Authorized Participant”), a registered broker-dealer and affiliate of the Sponsor, is the only Authorized Participant, and is party to a participant agreement with the Sponsor and the Trust. Additional Authorized Participants may be added at any time, subject to the discretion of the Sponsor. Liquidity Providers who are unaffiliated with the Trust may be engaged from time to time and at any time.

The custodian of the Trust is Coinbase Custody Trust Company, LLC (the “Custodian”), a third-party service provider. The Custodian is responsible for safeguarding the ETC, Incidental Rights, and IR Virtual Currency held by the Trust, and holding the private key(s) that provide access to the Trust’s digital wallets and vaults.

The transfer agent for the Trust (the “Transfer Agent”) is Continental Stock Transfer & Trust Company. The responsibilities of the Transfer Agent are to maintain creations, redemptions, transfers, and distributions of the Trust’s Shares which are primarily held in book-entry form.

On May 2, 2018, the Trust received notice that its Shares were qualified for public trading on the OTCQX Best Market® (“OTCQX”) of OTC Markets Group Inc. The Trust’s trading symbol on OTCQX is “ETCG” and the CUSIP number for its Shares is 38963Q107.

The Trust may also receive Incidental Rights and/or IR Virtual Currency as a result of the Trust’s investment in ETC, in accordance with the terms of the Trust Agreement. Incidental Rights are rights to claim, or otherwise establish dominion and control over, any virtual currency or other asset or right, which rights are incident to the Trust’s ownership of ETC and arise without any action of the Trust, or of the Sponsor or Trustee on behalf of the Trust; IR Virtual Currency is any virtual currency tokens, or other asset or right, received by the Trust through the exercise (subject to the applicable provisions of the Trust Agreement) of any Incidental Right.

2. Summary of Significant Accounting Policies

In the opinion of management of the Sponsor of the Trust, all adjustments (which include normal recurring adjustments) necessary to present fairly the financial position as of September 30, 2025 and December 31, 2024 and results of operations for the three and nine months ended September 30, 2025 and 2024 have been made. The results of operations for the periods presented are not necessarily indicative of the results of operations expected for the full year. These unaudited financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2024 included in our Annual Report.

The following is a summary of significant accounting policies followed by the Trust:

The financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). The Trust qualifies as an investment company for accounting purposes pursuant to the accounting and reporting guidance under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, Financial Services—Investment Companies. The Trust uses fair value as its method of accounting for ETC 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 of 1940. 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.

The Trust conducts its transactions in ETC, including receiving ETC for the creation of Shares and delivering ETC for the redemption of Shares and for the payment of the Sponsor’s Fee. At this time, the Trust is not accepting redemption requests from shareholders. Since its inception, the Trust has not held cash or cash equivalents. The Sponsor will determine the Trust’s net asset value (“NAV”) on each business day as of 4:00 p.m., New York time, or as soon thereafter as practicable.

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 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 ETC 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 ETC 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 ETC 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 Quarterly 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 ETC 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 ETC received by the Trust in connection with a creation order is recorded by the Trust at the fair value of ETC 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 Transactions and Revenue Recognition

The Trust considers investment transactions to be the receipt of ETC for Share creations and the delivery of ETC for Share redemptions or for payment of expenses in ETC. At this time, the Trust is not accepting redemption requests from shareholders. 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 ETC.

Fair Value Measurement

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the ‘exit price’) in an orderly transaction between market participants at the measurement date.

U.S. GAAP utilizes a fair value hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are those that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Trust. Unobservable inputs reflect the Trust’s assumptions about the inputs market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.

The fair value hierarchy is categorized into three levels based on the inputs as follows:

•

Level 1 – Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Trust has the ability to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, these valuations do not entail a significant degree of judgment.

•

Level 2 – Valuations based on quoted prices in markets that are not active or for which significant inputs are observable, either directly or indirectly.

•

Level 3 – Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

The availability of valuation techniques and observable inputs can vary by investment. To the extent that valuations are based on sources that are less observable or unobservable in the market, the determination of fair value requires more judgment. Fair value estimates do not necessarily represent the amounts that may be ultimately realized by the Trust.

Segment Reporting

The Chief Executive Officer and Chief Financial Officer of the Sponsor act as the Trust’s chief operating decision maker (“CODM”). The Trust represents a single operating segment, as the CODM monitors the operating results of the Trust as a whole and the Trust’s passive investment objective is pre-determined in accordance with the terms of the Trust Agreement. The financial information in the form of the Trust’s total returns, expense ratios and changes in net assets (i.e., changes in net assets resulting from operations and capital share transactions), which are used by the CODM to assess the segment’s performance, are consistent with that presented within the Trust’s financial statements. Segment assets are reflected on the accompanying Statements of Assets and Liabilities as Total assets and the only significant segment expense, the Sponsor’s fee, related party, is included in the accompanying Statements of Operations.

3. Fair Value of ETC

ETC is held by the Custodian on behalf of the Trust and is carried at fair value. As of September 30, 2025 and December 31, 2024, the Trust held 11,054,961.67837105 and 11,263,626.25503150 ETC, respectively.

The Trust determined the fair value per ETC to be $18.38 and $25.13 on September 30, 2025 and December 31, 2024, respectively, using the price provided at 4:00 p.m., New York time, by the Digital Asset Trading Platform Market considered to be the Trust’s principal market (Coinbase).

The following represents the changes in quantity of ETC and the respective fair value:


(Amounts in thousands, except ETC amounts)	Quantity			Fair Value

Net realized gain on investment in ETC		-			2,554
Balance at September 30, 2025	11,054,961.67837105			$	203,190

4. Creations and Redemptions of Shares

At September 30, 2025 and December 31, 2024, there were an unlimited number of Shares authorized by the Trust. The Trust creates (and, should the Trust commence a redemption program, redeems) Shares from time to time, but only in one or more Baskets. The creation and redemption of Baskets on behalf of investors are made by the Authorized Participant in exchange for the delivery of ETC to the Trust or the distribution of ETC by the Trust. The amount of ETC required for each Creation Basket or redemption Basket is determined by dividing (x) the amount of ETC owned by the Trust at 4:00 p.m., New York time, on such trade date of a creation or redemption order, after deducting the amount of ETC representing the U.S. dollar value of accrued but unpaid fees and expenses of the Trust, by (y) the number of Shares outstanding at such time and multiplying the quotient obtained by 100. Each Share represented approximately 0.7900 and 0.8049 of one ETC at September 30, 2025 and December 31, 2024, respectively. The decrease in the amount of ETC represented by each Share is primarily a result of the periodic withdrawal of ETC to pay the Sponsor’s Fee.

The cost basis of investments in ETC recorded by the Trust is the fair value of ETC, as determined by the Trust, at 4:00 p.m., New York time, on the date of transfer to the Trust by the Authorized Participant, or Liquidity Provider, based on the Creation Baskets. The cost basis recorded by the Trust may differ from proceeds collected by the Authorized Participant from the sale of each Share to investors. The Authorized Participant or Liquidity Provider may realize significant profits buying, selling, creating, and, if permitted, redeeming Shares as a result of changes in the value of Shares or ETC.

At this time, the Trust is not operating a redemption program and is not accepting redemption requests. Subject to receipt of regulatory approval and approval by the Sponsor in its sole discretion, the Trust may in the future operate a redemption program. The Trust currently has no intention of seeking regulatory approval to operate an ongoing redemption program.

5. Income Taxes

The Sponsor takes 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.

If the Trust were 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, including forks, airdrops and similar occurrences 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. In addition, tax information reports provided to beneficial owners of Shares would be made in a different form. 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.

In accordance with U.S. GAAP, the Trust has defined the threshold for recognizing the benefits of tax positions in the financial statements as “more-likely-than-not” to be sustained by the applicable taxing authority and requires measurement of a tax position meeting the “more-likely-than-not” threshold, based on the largest benefit that is more than 50% likely to be realized. Tax positions deemed to meet the “more-likely-than-not” threshold are recorded as a tax benefit in the current period. As of, and during the periods ended September 30, 2025 and December 31, 2024, the Trust did not have a liability for any unrecognized tax amounts. However, the Sponsor’s conclusions concerning its determination of “more-likely-than-not” tax positions may be subject to review and adjustment at a later date based on factors including, but not limited to, further implementation guidance, and ongoing analyses of and changes to tax laws, regulations and interpretations thereof.

The Sponsor of the Trust has evaluated whether or not there are uncertain tax positions that require financial statement recognition and has determined that no reserves for uncertain tax positions related to federal, state and local income taxes existed as of September 30, 2025 or December 31, 2024.

6. Related Parties

The Trust considered the following entities, their directors, and certain employees to be related parties of the Trust as of September 30, 2025: DCG, GSO, GSIS, and Grayscale Securities. As of both September 30, 2025 and December 31, 2024, 14,977 Shares of the Trust were held by related parties of the Trust.

In accordance with the Trust Agreement governing the Trust, the Trust pays a fee to the Sponsor, calculated as 2.5% of the aggregate value of the Trust’s assets, less its liabilities (which include any accrued but unpaid expenses up to, but excluding, the date of calculation), as calculated and published by the Sponsor or its delegates in the manner set forth in the Trust Agreement (the “Sponsor’s Fee”). The Sponsor’s Fee accrues daily in U.S. dollars and is payable in ETC, monthly in arrears. The amount of ETC payable in respect of each daily U.S. dollar accrual will be determined by reference to the same U.S. dollar value of ETC used to determine such accrual. For purposes of these financial statements, the U.S. dollar value of ETC is determined by reference to the Digital Asset Trading Platform Market that the Trust considers its principal market as of 4:00 p.m., New York time, on each valuation date. The Trust held no Incidental Rights or IR Virtual Currency as of September 30, 2025 and December 31, 2024. No Incidental Rights or IR Virtual Currencies have been distributed in payment of the Sponsor’s Fee during the three and nine months ended September 30, 2025 and 2024.

As partial consideration for receipt of the Sponsor’s Fee, 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 marketing fees; administrator fees, if any; custodian fees; transfer agent fees; trustee fees; the 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; ordinary course legal fees and expenses; audit fees; regulatory fees, including, if applicable, any fees relating to the registration of the Shares under the Securities Act or the Exchange Act; printing and mailing costs; the costs of maintaining the Trust’s website and applicable license fees (together, the “Sponsor-paid Expenses”), 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 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 (including in connection with any Incidental Rights and any IR Virtual Currency), 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”). In such circumstances, the Sponsor or its delegate (i) will instruct the Custodian to withdraw from the Digital Asset Account ETC, Incidental Rights and/or IR Virtual Currency in such quantity as may be necessary to permit payment of such Additional Trust Expenses and (ii) may either (x) cause the Trust (or its delegate) to convert such ETC, Incidental Rights and/or IR Virtual Currency 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 ETC, Incidental Rights and/or IR Virtual Currency in kind to the Sponsor, in each case in such quantity as may be necessary to permit payment of such Additional Trust Expenses.

For the three months ended September 30, 2025 and 2024, the Trust incurred Sponsor’s Fees of $1,439,247 and $1,434,671, respectively. For the nine months ended September 30, 2025 and 2024, the Trust incurred Sponsor’s Fees of $4,129,653 and $5,399,148, respectively. As of September 30, 2025 and December 31, 2024, there were no accrued and unpaid Sponsor’s Fees. In addition, the Sponsor may pay Additional Trust Expenses on behalf of the Trust, which are reimbursable by the Trust to the Sponsor. For the three and nine months ended September 30, 2025 and 2024, the Sponsor did not pay any Additional Trust Expenses on behalf of the Trust.

by DCG of up to an aggregate total of $200 million worth of Shares of the Trust and shares of any of the following five investment products the Sponsor also acts as the sponsor and manager of, including Grayscale Bitcoin Trust ETF (NYSE Arca: GBTC), Grayscale Bitcoin Cash Trust (BCH) (OTCQX: BCHG), Grayscale CoinDesk Crypto 5 ETF (NYSE Arca: GDLC), Grayscale Ethereum Trust ETF (NYSE Arca: ETHE), and Grayscale Stellar Lumens Trust (XLM) (OTCQX: GXLM). This increased DCG’s prior authorization to purchase up to $50 million worth of Shares by up to a maximum of $200 million. The Share purchase authorization does not obligate DCG to acquire any specific number of Shares in any period, and may be expanded, extended, modified, or discontinued at any time. From June 21, 2021 through December 31, 2021, DCG purchased $45.3 million worth of Shares of the Trust. From January 1, 2022 through September 30, 2025, DCG had not purchased any Shares of the Trust under this authorization.

7. Risks and Uncertainties

The Trust is subject to various risks including market risk, liquidity risk, and other risks related to its concentration in a single asset, ETC. Investing in ETC is currently highly speculative and volatile.

The Principal Market NAV of the Trust, calculated by reference to the principal market price in accordance with U.S. GAAP, relates primarily to the value of the ETC held by the Trust, and fluctuations in the price of ETC could materially and adversely affect an investment in the Shares of the Trust. The price of ETC has a limited history. During such history, ETC prices have been volatile and subject to influence by many factors, including the levels of liquidity. If Digital Asset Markets continue to experience significant price fluctuations, the Trust may experience losses. Several factors may affect the price of ETC, including, but not limited to, global ETC supply and demand, theft of ETC from global trading platforms or vaults, competition from other forms of digital currency or payment services, global or regional political, economic or financial conditions, and other unforeseen events and situations.

The ETC held by the Trust are commingled, and the Trust’s shareholders have no specific rights to any specific ETC. In the event of the insolvency of the Trust, its assets may be inadequate to satisfy a claim by its shareholders.

There is currently no clearing house for ETC, nor is there a central or major depository for the custody of ETC. There is a risk that some or all of the Trust’s ETC could be lost or stolen. There can be no assurance that the Custodian will maintain adequate insurance or that such coverage will cover losses with respect to the Trust’s ETC. Further, transactions in ETC are irrevocable. Stolen or incorrectly transferred ETC may be irretrievable. As a result, any incorrectly executed ETC transactions could adversely affect an investment in the Shares.

The Securities and Exchange Commission (the “SEC”), at least under the prior administration, has stated that certain digital assets may be considered “securities” under the federal securities laws. 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. A number of SEC and SEC staff actions with respect to a variety of digital assets demonstrate this difficulty. For example, public though non-binding, statements by senior officials at the SEC have indicated that the SEC did not consider Bitcoin or Ether to be securities, and does not currently consider Bitcoin to be a security. In addition, the SEC appears to have implicitly taken the view that Ether is not a security (i) by not objecting to Ether futures trading on Commodity Futures Trading Commission-regulated markets under rules designed for futures on non-security commodity underliers and (ii) by approving the listing and trading of exchange-traded products (“ETPs”) that invest in Ether (i.e., approving the redemption of shares of such ETPs) under the rules for commodity-based trust shares, without requiring these ETPs to be registered as investment companies. Likewise, in various courts filings and arguments the SEC has distinguished Ether from assets that it claimed were securities, and in judicial opinions, courts have accepted or even assumed that Ether is not a security. Moreover, in a recent settlement with another market participant relating to allegations that it acted as an unregistered broker-dealer for facilitating trading in certain digital assets, the SEC highlighted that the firm would cease trading in all digital assets other than Bitcoin, Bitcoin Cash and Ether—activity that, if the SEC believed Ether was presently a security—would continue to constitute unregistered brokerage activity. The SEC staff has also provided informal assurances via no-action letter to a handful of promoters that their digital assets are not securities. Moreover, the SEC’s Division of Corporation Finance has published statements that it does not consider, under certain circumstances, “meme coins” or some stablecoins to be securities. However, such statements may be withdrawn at any time without notice and comment by the Division of Corporation Finance at the SEC or the SEC itself. In addition, the SEC has brought enforcement actions against the issuers and promoters of several other digital assets on the basis that the digital assets in question are securities and has not formally or explicitly confirmed that it does not deem Ether to be a security. These developments demonstrate the difficulty in applying the federal securities laws to digital assets generally. 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 assets-based investment vehicles, and clarity regarding digital asset custody, lending, and staking. However, the efforts of the crypto task force have only just begun, and how or whether the SEC regulates digital asset activity in the future remains to be seen.

If ETC is determined to be a “security” under federal or state securities laws by the SEC or any other agency, or in a proceeding in a court of law or otherwise, it may have material adverse consequences for ETC. For example, it may become more difficult for ETC to be traded, cleared and custodied as compared to other digital assets that are not considered to be securities, which could, in turn, negatively affect the liquidity and general acceptance of ETC and cause users to migrate to other digital assets. As such, any determination that ETC is a security under federal or state securities laws may adversely affect the value of ETC and, as a result, an investment in the Shares.

In addition, if ETC is in fact a security, the Trust could be considered an unregistered “investment company” under the Investment Company Act of 1940, 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 securities and there is no guarantee that the Sponsor will be able to register the Trust under the Investment Company Act of 1940 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.

To the extent a private key, held by the Custodian, required to access an ETC address is lost, destroyed or otherwise compromised and no backup of the private keys are accessible, the Trust may be unable to access the ETC controlled by the private key and the private key will not be capable of being restored by the Ethereum Classic Network. The processes by which ETC transactions are settled are dependent on the ETC peer-to-peer network, and as such, the Trust is subject to operational risk. A risk also exists with respect to previously unknown technical vulnerabilities, which may adversely affect the value of ETC.

The Trust relies on third-party service providers to perform certain functions essential to its operations. Any disruptions to the Trust’s service providers’ 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.

The Sponsor and the Trust may be subject to various litigation, regulatory investigations, and other legal proceedings that arise in the ordinary course of its business.

An individual shareholder’s return, ratios, and per Share performance may vary from those presented above based on the timing of Share transactions. The amount shown for a Share outstanding throughout the period may not correlate with the Statement of Operations for the period due to the number of Shares issued in Creations occurring at an operational value derived from an operating metric as defined in the Trust Agreement.

Total return is calculated assuming an initial investment made at the Principal Market NAV at the beginning of the period and assuming redemption on the last day of the period.

9. Indemnifications

In the normal course of business, the Trust enters into certain contracts that provide a variety of indemnities, including contracts with the Sponsor and affiliates of the Sponsor, DCG and its officers, directors, employees, subsidiaries and affiliates, and the Custodian as well as others relating to services provided to the Trust. The Trust’s maximum exposure under these and its other indemnities is unknown. However, no liabilities have arisen under these indemnities in the past and, while there can be no assurances in this regard, there is no expectation that any will occur in the future. Therefore, the Sponsor does not consider it necessary to record a liability in this regard.

10. Subsequent Events

On October 22, 2025, GSO Intermediate Holdings Corporation (“GSOIH”), a Delaware corporation which was the sole managing member of GSO, a Delaware limited liability company which is the sole member of the Sponsor, consummated an internal corporate reorganization (the “Management Reorganization”). Pursuant to the Management Reorganization, 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.

Also in connection with the Management Reorganization, on October 22, 2025, DCG Grayscale Holdco, LLC (“DCG Holdco”), the sole stockholder of Grayscale Investments, elected a board of directors (the “Board”) at Grayscale Investments. Prior to the Management Reorganization, GSOIH’s board of directors was responsible for managing and directing the affairs of the Sponsor. 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. Mr. Silbert is the Chairperson of the Board of Grayscale Investments.

DCG Holdco, Grayscale Investments, GSOIH, GSO and the Sponsor are all consolidated subsidiaries of Digital Currency Group, Inc.

The Sponsor does not expect the Management Reorganization to have any material impact on the operations of the Trust.

As of the close of business on October 31, 2025, the fair value of ETC determined in accordance with the Trust’s accounting policy was $15.99 per ETC.

There are no known events that have occurred that require disclosure other than that which has already been disclosed in these notes to the financial statements.

Item 2. 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 unaudited financial statements and related notes included elsewhere in this Quarterly 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 set forth under “Part II, Item 1A. Risk Factors” in this Quarterly Report, or in “Part I, Item 1A. Risk Factors” and “Forward-Looking Statements” or other sections of our Annual Report.

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. The Trust holds ETC and, from time to time on a periodic basis, issues Creation Baskets in exchange for deposits of ETC. As a passive investment vehicle, the Trust’s investment objective is for the value of the Shares (based on ETC per Share) to reflect the value of the ETC 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 ETC, the Shares are designed to provide investors with a cost-effective and convenient way to gain investment exposure to ETC. To date, the Trust has not met its investment objective and the Shares quoted on OTCQX have not reflected the value of the ETC held by the Trust, less the Trust’s expenses and other liabilities, but instead have traded at both premiums and discounts to such value, which at times have been substantial. 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.

On January 1, 2025, GSI consummated an internal corporate reorganization (the “Reorganization”), pursuant to which GSI, the Sponsor of the Trust prior to the Reorganization, merged with and into GSO, a Delaware limited liability company and a consolidated subsidiary of DCG, with GSO continuing as the surviving company (the “Merger”). As a result of the Merger, GSO succeeded by operation of law to all the rights, powers, privileges and franchises and became subject to all of the obligations, liabilities, restrictions and disabilities of GSI, including with respect to the Sponsor Contracts (as defined below), all as provided under the Delaware Limited Liability Company Act. The Reorganization has not had any material impact on the operations of the Trust.

In connection with the Reorganization, on January 1, 2025, and promptly following the effectiveness of the Merger, GSO assigned certain contracts pertaining to its role as Sponsor (as such term is defined in the Trust Agreement) of the Trust (such contracts, the “Sponsor Contracts”) to GSIS, a Delaware limited liability company and a wholly owned direct subsidiary of GSO, whereby GSIS assumed all of the rights and obligations of GSO under the Sponsor Contracts. Other than the assumption of the Sponsor Contracts by GSIS, the Reorganization does not alter the rights or obligations under any of the Sponsor Contracts.

In connection with the Reorganization, on January 1, 2025, and promptly following the effectiveness of the Merger, GSO and GSIS executed a Certificate of Admission, pursuant to which GSIS was admitted as an additional Sponsor of the Trust under the Trust Agreement, by and among GSO (as successor in interest to GSI), the Trustee, and the shareholders from time to time thereunder, as amended from time to time. GSIS shall be subject to the rights and obligations of a Sponsor under the Trust Agreement.

On January 3, 2025, GSO voluntarily withdrew as a Sponsor of the Trust pursuant to the terms of the Trust Agreement, and, effective May 3, 2025, GSIS became the sole remaining Sponsor of the Trust.

Critical Accounting Policies and Estimates

Investment Transactions and Revenue Recognition

The Trust considers investment transactions to be the receipt of ETC by the Trust in connection with Share creations and the delivery of ETC by the Trust in connection with Share redemptions or for payment of expenses in ETC. At this time, the Trust is not accepting redemption requests from shareholders. 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 ETC.

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 ETC 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 ETC 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.

In determining which of the eligible Digital Asset Markets is the Trust’s principal market, the Trust reviews these criteria in the following order:

•

Second, the Trust sorts these Digital Asset Markets from high to low by market-based volume and level of activity of ETC traded on each Digital Asset Market in the trailing twelve months.

•

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 ETC 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 (unaudited)

Financial Highlights for the Three and Nine Months Ended September 30, 2025 and 2024

(All amounts in the following table and the subsequent paragraphs, except Share, per Share, ETC and price of ETC amounts, are in thousands)


	Three Months Ended September 30,					Nine Months Ended September 30,
	2025		2024			2025			2024
Net realized and unrealized gain (loss) on investment in ETC	$	18,066	$	(44,340	)	$	(75,735	)	$	(25,607	)

Net assets(1)	$	203,190	$	222,952		$	203,190		$	222,952

(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 ETC 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 gain on investment in ETC for the three months ended September 30, 2025 was $18,066, which includes a realized gain of $912 on the transfer of ETC to pay the Sponsor’s Fee and net change in unrealized appreciation on investment in ETC of $17,154. Net realized and unrealized gain on investment in ETC for the period was driven by ETC price appreciation from $16.77 per ETC as of June 30, 2025, to $18.38 per ETC as of September 30, 2025. Net increase in net assets resulting from operations was $16,626 for the three months ended September 30, 2025, which consisted of the net realized and unrealized gain on investment in ETC, less the Sponsor’s Fee of $1,440. Net assets increased to $203,190 at September 30, 2025, a 9% increase for the three-month period. The increase in net assets resulted from the aforementioned ETC price appreciation, partially offset by the withdrawal of approximately 69,883 ETC to pay the foregoing Sponsor’s Fee.

Net realized and unrealized loss on investment in ETC for the three months ended September 30, 2024 was ($44,340), which includes a realized gain of $896 on the transfer of ETC to pay the Sponsor’s Fee and net change in unrealized appreciation on investment in ETC of ($45,236). Net realized and unrealized loss on investment in ETC for the period was driven by ETC price depreciation from $23.56 per ETC as of June 30, 2024, to $19.67 per ETC as of September 30, 2024. Net decrease in net assets resulting from operations was ($45,775) for the three months ended September 30, 2024, which consisted of the net realized and unrealized loss on investment in ETC, plus the Sponsor’s Fee of $1,435. Net assets decreased to $222,952 at September 30, 2024, a 17% decrease for the three-month period. The decrease in net assets resulted from the aforementioned ETC price depreciation and the withdrawal of approximately 71,455 ETC to pay the foregoing Sponsor’s Fee.

Net realized and unrealized loss on investment in ETC for the nine months ended September 30, 2025 was ($75,735), which includes a realized gain of $2,554 on the transfer of ETC to pay the Sponsor’s Fee and net change in unrealized appreciation on investment in ETC of ($78,289). Net realized and unrealized loss on investment in ETC for the period was driven by ETC price depreciation from $25.13 per ETC as of December 31, 2024, to $18.38 per ETC as of September 30, 2025. Net decrease in net assets resulting from operations was ($79,865) for the nine months ended September 30, 2025, which consisted of the net realized and unrealized loss on investment in ETC, plus the Sponsor’s Fee of $4,130. Net assets decreased to $203,190 at September 30, 2025, a 28% decrease for the nine-month period. The decrease in net assets resulted from the aforementioned ETC price depreciation and the withdrawal of approximately 208,664 ETC to pay the foregoing Sponsor’s Fee.

Net realized and unrealized loss on investment in ETC for the nine months ended September 30, 2024 was ($25,607), which includes a realized gain of $3,782 on the transfer of ETC to pay the Sponsor’s Fee and net change in unrealized appreciation on investment in ETC of ($29,389). Net realized and unrealized loss on investment in ETC for the period was driven by ETC price depreciation from $21.99 per ETC as of December 31, 2023, to $19.67 per ETC as of September 30, 2024. Net decrease in net assets resulting from operations was ($31,006) for the nine months ended September 30, 2024, which consisted of the net realized and unrealized loss on investment in ETC, plus the Sponsor’s Fee of $5,399. Net assets decreased to $222,952 at September 30, 2024, a 12% decrease for the nine-month period. The decrease in net assets resulted from the aforementioned ETC price depreciation and the withdrawal of approximately 214,142 ETC to pay the foregoing Sponsor’s Fee.

Cash Resources and Liquidity

The Trust has not had a cash balance at any time since inception. When selling ETC, Incidental Rights and/or IR Virtual Currency in the Digital Asset Market to pay Additional Trust Expenses on behalf of the Trust, the Sponsor endeavors to sell the exact amount of ETC, Incidental Rights and/or IR Virtual Currency needed to pay expenses in order to minimize the Trust’s holdings of assets other than ETC. 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.

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 during the periods covered by this Quarterly Report was 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.

Prior to February 23, 2024, Principal Market NAV was referred to as NAV and Principal Market NAV per Share was referred to as NAV per Share.

(3)

The Trust’s NAV per Share is derived from the Index Price, as represented by the Index as of 4:00 p.m., New York time, on the valuation date.

Prior to February 23, 2024, NAV was referred to as Digital Asset Holdings and NAV per Share was referred to as Digital Asset Holdings per Share. See “Item 1.

Subject to receipt of regulatory approval from the SEC and approval by the Sponsor in its sole discretion, the Trust may in the future operate a redemption program. The Trust currently has no intention of seeking regulatory approval to operate an ongoing redemption program.
