GRAYSCALE BITCOIN TRUST ETF

NOTES TO THE UNAUDITED FINANCIAL STATEMENTS

1. Organization

Grayscale Bitcoin Trust ETF (the “Trust”) is a Delaware Statutory Trust that was formed on September 13, 2013 and commenced operations on September 25, 2013. The Trust’s investment objective is for the value of the Shares (based on Bitcoin per Share) to reflect the value of the Bitcoin held by the Trust, less the Trust’s expenses and other liabilities. The Trust issues Shares only in one or more blocks of 10,000 Shares (a block of 10,000 Shares is called a “Basket”) only to certain authorized participants (“Authorized Participants”) in exchange for Bitcoin.

The Trust’s registration statement on Form S-3 relating to its continuous public offering of Shares was declared effective by the Securities and Exchange Commission (“SEC”) on January 10, 2024 and the Shares were listed and began trading on NYSE Arca, Inc. (“NYSE Arca”) under the symbol “GBTC” on January 11, 2024 (the “Uplisting Date”).

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.

Liquidity Providers facilitate the purchase and sale of Bitcoin in connection with cash orders for creations or redemptions of Baskets. The Liquidity Providers with which GSIS, acting in its capacity as the “Liquidity Engager,” will engage in Bitcoin 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 GSIS 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. The Liquidity Engager may engage additional Liquidity Providers who are unaffiliated with the Trust in the future.

Coinbase, Inc. is the prime broker (the “Prime Broker”) of the Trust, and Coinbase Custody Trust Company, LLC is the custodian (the “Custodian”). 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 Bitcoin 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. The Custodian is responsible for safeguarding the Bitcoin held by the Trust, and holding the private key(s) that provide access to the Trust’s digital wallets and vaults. Additionally, Anchorage Digital Bank N.A. (the “Additional Custodian”) is an available alternative custodian of the Trust. Pursuant to the Anchorage Digital Custodian Agreement, Anchorage Digital will provide services related to custody and safekeeping of the Trust’s Bitcoin holdings.

The transfer agent for the Trust (the “Transfer Agent”) is The Bank of New York Mellon. The responsibilities of the Transfer Agent are to (1) facilitate the issuance and redemption of shares of the Trust; (2) respond to correspondence by Trust shareholders and others relating to its duties; (3) maintain shareholder accounts; and (4) make periodic reports to the Trust. The co-transfer agent for the Trust (the “Co-Transfer Agent”) is Continental Stock Transfer & Trust Company.

The administrator for the Trust (the “Administrator”) is BNY Mellon Asset Servicing, a division of The Bank of New York Mellon. BNY Mellon Asset Servicing provides administration and accounting services to the Trust. The Administrator’s fees are paid on behalf of the Trust by the Sponsor.

The marketing agent for the Trust (the “Marketing Agent”) is Foreside Fund Services, LLC. The Marketing Agent 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.

On March 25, 2015, the Trust received notice that its Shares were qualified for public trading on the OTCQX Best Market® (“OTCQX”) of OTC Markets Group Inc. Until January 10, 2024, the Trust’s trading symbol on OTCQX was “GBTC.” On January 11, 2024, Shares of the Trust began trading on NYSE Arca following the effectiveness of the Trust’s registration statement on Form S-3, as amended (File No. 333-275079). The Trust’s trading symbol on NYSE Arca is “GBTC” and the CUSIP number for its Shares is 389637109.

The Trust may also receive Incidental Rights and/or IR Virtual Currency as a result of the Trust’s investment in Bitcoin, 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 Bitcoin 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. The Sponsor has committed to cause the Trust to abandon irrevocably for no direct or indirect consideration, effective immediately prior to each time at which the Trust creates or redeems Shares, all Incidental Rights and IR Virtual Currency to which it would otherwise be entitled as of such time. In furtherance of that commitment, the Prime Broker Agreement provides that the Trust is abandoning irrevocably, for no direct or indirect consideration, effective immediately prior to each Creation Time and each Redemption Time, all Incidental Rights or IR Virtual Currency to which it would otherwise be entitled as of such time. 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. Because the Sponsor has now 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.

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 March 31, 2026 and December 31, 2025 and results of operations for the three months ended March 31, 2026 and 2025 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, 2025 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. As such, the Trust is exempt from the requirement to present a statement of cash flows pursuant to ASC Topic 230, Statement of Cash Flows. Accordingly, a statement of cash flows has not been presented. The Trust uses fair value as its method of accounting for Bitcoin 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, as amended (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.

The Trust conducts its transactions in Bitcoin, including receiving Bitcoin for the creation of Shares and delivering Bitcoin for the redemption of Shares and for the payment of the Sponsor’s Fee. 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.

Cash and Cash Equivalents

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.

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 Bitcoin 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 Bitcoin 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.

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 Bitcoin 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.

Investment Transactions and Revenue Recognition

The Trust considers investment transactions to be the receipt of Bitcoin for Share creations and the delivery of Bitcoin for Share redemptions or for payment of expenses in Bitcoin. 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 Bitcoin.

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 Bitcoin

Bitcoin is held by the Custodian on behalf of the Trust and is carried at fair value. As of March 31, 2026 and December 31, 2025, the Trust held 154,703.84755988 and 165,591.49612215 Bitcoin, respectively.

The Trust determined the fair value per Bitcoin to be $67,805.29 and $87,549.41 on March 31, 2026 and December 31, 2025, 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 (Crypto.com).

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

4. Creations and Redemptions of Shares

The Trust creates and redeems Shares from time to time, but only in one or more Baskets issued to the Authorized Participant in exchange for the delivery of Bitcoin to the Trust or the distribution of Bitcoin by the Trust. The amount of Bitcoin required for each Creation Basket or Redemption Basket is determined by dividing (x) the amount of Bitcoin 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 Bitcoin 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 10,000. Each Share represented approximately 0.0008 of one Bitcoin at both March 31, 2026 and December 31, 2025.

As of the date of this Quarterly Report, Authorized Participants may only submit orders to create or redeem Shares through transactions that are referred to as “cash orders”, as the agreements with Authorized Participants do not currently provide for in-kind creations and redemptions.

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 March 31, 2026 and December 31, 2025, 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 March 31, 2026 or December 31, 2025.

6. Related Parties

The Trust considered the following entities, their directors, and certain employees to be related parties of the Trust as of March 31, 2026: DCG, GSO, GSIS and Grayscale Securities, LLC. As of March 31, 2026 and December 31, 2025, 5,828 and 9,302 Shares of the Trust were held by related parties of the Trust, respectively.

In accordance with the Trust Agreement governing the Trust, the Trust pays a fee to the Sponsor, calculated as 1.5% 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 Bitcoin, daily in arrears. The amount of Bitcoin payable in respect of each daily U.S. dollar accrual will be determined by reference to the same U.S. dollar value of Bitcoin used to determine such accrual. For purposes of these financial statements, the U.S. dollar value of Bitcoin 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 March 31, 2026 and December 31, 2025. No Incidental Rights or IR Virtual Currencies have been distributed in payment of the Sponsor’s Fee during the three months ended March 31, 2026 and 2025.

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, 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 Vault Balance Bitcoin 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 Bitcoin 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 Bitcoin 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 March 31, 2026 and 2025, the Trust incurred Sponsor’s Fees of $44,984,658 and $68,938,532, respectively. As of March 31, 2026 and December 31, 2025, 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 months ended March 31, 2026 and 2025 the Sponsor did not pay any Additional Trust Expenses on behalf of the Trust.

On March 10, 2021, the Board of the Sponsor approved the purchase by DCG, the indirect parent company of the Sponsor, of up to $250 million worth of Shares of the Trust. Subsequently, DCG authorized such purchase. On April 30, 2021, the Board approved the purchase by DCG of up to $750 million worth of Shares of the Trust. This increased DCG’s prior authorization to purchase up to $250 million worth of Shares by $500 million. On October 20, 2021, the Board of the Sponsor approved the purchase by DCG, the parent company of the Sponsor, of up to $1 billion worth of Shares of the Trust. Subsequently, DCG authorized such purchase. This increased DCG’s prior authorization to purchase up to $750 million worth of Shares by $250 million. On March 2, 2022, the Board approved the purchase 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 Cash Trust (BCH) (OTCQX: BCHG), Grayscale CoinDesk Crypto 5 ETF (NYSE Arca: GDLC), Grayscale Ethereum Staking ETF (NYSE Arca: ETHE), Grayscale Ethereum Classic Trust (ETC) (OTCQX: ETCG), and Grayscale Stellar Lumens Trust (XLM) (OTCQX:GXLM). This increased DCG’s prior authorization to purchase up to $1 billion 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 March 10, 2021 through June 30, 2022, DCG purchased a total of $771.8 million worth of Shares of the Trust under this authorization. From July 1, 2022 through March 31, 2026, DCG had not purchased any Shares of the Trust under this authorization.

7. Concentration Risk

The Trust’s investment portfolio is concentrated in Bitcoin, and its net asset value and results of operations are directly affected by the price of Bitcoin, which has historically been highly volatile. As a result, the Trust may experience significant fluctuations in net asset value, including periods of substantial losses. This concentration also exposes the Trust to risks specific to Bitcoin and its supporting infrastructure, including market liquidity constraints and operational or cybersecurity risks associated with the custody and transfer of Bitcoin.

8. Financial Highlights Per Share Performance

Expenses		-1.50	%		-1.50	%

Ratios of net investment loss and expenses to average net assets have been annualized.

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 and Additional 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

As previously disclosed, on October 22, 2025, GSOIH consummated an internal corporate reorganization (the “Management Reorganization”). As a result of the Management Reorganization as of October 22, 2025, (i) Grayscale Investments, Inc. (“Grayscale Investments”) is the sole managing member of GSO, the sole member of the Sponsor and (ii) the Board of Directors of Grayscale Investments became responsible for managing and directing the affairs of the Sponsor, and consists of Barry Silbert, Mark Shifke, Simon Koster, Peter Mintzberg and Edward McGee.

On May 4, 2026, a Board of Managers of Grayscale Investments Sponsors, LLC was created to manage and direct the affairs of the Sponsor, under authority delegated by the board of Grayscale Investments. While the board of Grayscale Investments retains overall oversight of Grayscale Investments and its subsidiaries as a whole, including the Sponsor, the Board of Managers of the Sponsor consists of Peter Mintzberg, Edward McGee, and Craig Salm. Mr. Mintzberg, Mr. McGee, and Mr. Salm are granted authority to manage the day-to-day affairs of the Sponsor under the amended and restated limited liability company agreement of the Sponsor.

The Sponsor has evaluated all subsequent events through the issuance of the financial statements and has noted no other events requiring adjustment or additional disclosure in the financial statements other than the item noted above.

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 Bitcoin and, from time to time on a periodic basis, issues Creation Baskets in exchange for deposits of Bitcoin. On January 10, 2024, in connection with the approval of application under Rule 19b-4 of the Securities Exchange Act of 1934 and the effectiveness of the registration statement on Form S-3, the Sponsor authorized the commencement of a redemption program. Shares of the Trust began trading on NYSE Arca on January 11, 2024, following the effectiveness of the Trust's registration statement on Form S-3. 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 Bitcoin. 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 Bitcoin per Share) to reflect the value of the Bitcoin 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 Bitcoin, the Shares are designed to provide investors with a cost-effective and convenient way to gain investment exposure to Bitcoin. 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 April 1, 2026, the Trust valued the Bitcoin held by the Trust for operational purposes by reference to the CoinDesk Bitcoin Price Index (XBX). As of April 1, 2026, the Index is the CoinDesk Bitcoin Benchmark Rate which is used to calculate the NAV and NAV per Share. Prior to April 1, 2026, references to the “Index” in the Trust’s filings with the SEC, including this Quarterly Report on Form 10-Q, refer to the CoinDesk Bitcoin Price Index (XBX). From and after April 1, 2026, references to the “Index” in the Trust’s filings with the SEC are to the CoinDesk Bitcoin Benchmark Rate.

Critical Accounting Policies and Estimates

Investment Transactions and Revenue Recognition

The Trust considers investment transactions to be the receipt of Bitcoin by the Trust in connection with Share creations and the delivery of Bitcoin by the Trust in connection with Share redemptions or for payment of expenses in Bitcoin. 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 Bitcoin.

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 Bitcoin 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 Bitcoin 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 Bitcoin 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:

•

Second, the Trust sorts these Digital Asset Markets from high to low by market-based volume and level of activity of Bitcoin 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 Bitcoin 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 Months Ended March 31, 2026 and 2025

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


	Three Months Ended March 31,
	2026			2025
Net realized and unrealized loss on investment in Bitcoin	$	(3,138,125	)	$	(2,130,572	)
Net decrease in net assets resulting from operations	$	(3,183,109	)	$	(2,199,511	)
Net assets(1)	$	10,489,739		$	15,948,122

(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 Bitcoin 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 Bitcoin for the three months ended March 31, 2026 was ($3,138,125), which includes a realized gain of $34,495 on the transfer of Bitcoin to pay the Sponsor’s Fee, a realized gain of $816,008 on the sale of Bitcoin to meet redemptions, and net change in unrealized appreciation/depreciation on investment in Bitcoin of ($3,988,628). Net realized and unrealized loss on investment in Bitcoin for the period was driven by Bitcoin price depreciation from $87,549.41 per Bitcoin as of December 31, 2025, to $67,805.29 per Bitcoin as of March 31, 2026. Net decrease in net assets resulting from operations was ($3,183,109) for the three months ended March 31, 2026, which consisted of the net realized and unrealized loss on investment in Bitcoin, plus the Sponsor’s Fee of $44,984. Net assets decreased to $10,489,739 at March 31, 2026, a 28% decrease for the three-month period. The decrease in net assets resulted from the aforementioned Bitcoin price depreciation, the withdrawal of approximately 586 Bitcoin to pay the foregoing Sponsor’s Fee, and the redemption of approximately 13,180 Bitcoin with a value of $1,048,617 from the Trust, partially offset by the contribution of approximately 2,878 Bitcoin with a value of $224,028 to the Trust in connection with Share creations during the period.

Net realized and unrealized loss on investment in Bitcoin for the three months ended March 31, 2025 was ($2,130,572), which includes a realized gain of $57,881 on the transfer of Bitcoin to pay the Sponsor’s Fee, a realized gain of $1,029,931 on the sale of Bitcoin to meet redemptions, and net change in unrealized appreciation/depreciation on investment in Bitcoin of ($3,218,384). Net realized and unrealized loss on investment in Bitcoin for the period was driven by Bitcoin price depreciation from $93,390.22 per Bitcoin as of December 31, 2024, to $82,443.85 per Bitcoin as of March 31, 2025. Net decrease in net assets resulting from operations was ($2,199,511) for the three months ended March 31, 2025, which consisted of the net realized and unrealized loss on investment in Bitcoin, plus the Sponsor’s Fee of $68,939. Net assets decreased to $15,948,122 at March 31, 2025, a 17% decrease for the three-month period. The decrease in net assets resulted from the aforementioned Bitcoin price depreciation, the withdrawal of approximately 737 Bitcoin to pay the foregoing Sponsor’s Fee, and the redemption of approximately 13,185 Bitcoin with a value of $1,227,181 from the Trust, partially offset by the contribution of approximately 1,965 Bitcoin with a value of $192,570 to the Trust in connection with Share creations during the period.

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 Bitcoin in the Digital Asset Market to pay Additional Trust Expenses on behalf of the Trust, the Sponsor endeavors to sell the exact amount of Bitcoin needed to pay expenses in order to minimize the Trust’s holdings of assets other than Bitcoin. 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 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.

Selected Operating Data


	As of March 31,
	2026		2025
Price of Bitcoin on principal market	$	67,805.29	$	82,443.85

(1)

The Principal Market NAV and Principal Market NAV per Share are calculated using the fair value of Bitcoin based on the price provided by 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, in accordance with U.S. GAAP.

(2)

The Trust’s NAV and NAV per Share are derived from the Index Price as represented by the Index as of 4:00 p.m., New York time, on the valuation date. The Trust’s NAV per Share is calculated using a non-GAAP methodology where the price is derived from multiple Digital Asset Trading Platforms. The Digital Asset Trading Platforms included in the Index (the “Constituent Trading Platforms”) as of both March 31, 2026 and 2025 were Coinbase, Bitstamp by Robinhood, Kraken, LMAX Digital, Crypto.com, and Bullish. The Digital Asset Trading Platforms included in the Index as of April 30, 2026 were Binance, Bitstamp by Robinhood, Bullish, Bybit, Crypto.com, GATE, Gemini, Hashkey, Kraken, LMAX Digital, and OKX. See “Item 1. Business—Overview of the Bitcoin Industry and Market—Bitcoin Value—The Index and the Index Price” in our Annual Report for a description of the Index and the Index Price.

The Trust reflects creations and redemptions and the Bitcoin for proceeds receivable or payable with respect to such creations and redemptions, respectively, on the trade date, which is the business day an accepted creation or redemption order is placed by an Authorized Participant. Creation and redemption orders are settled on T+1 or T+2, as established at the time of order placement, and therefore the Bitcoin for proceeds receivable or payable with respect to such creations and redemptions, respectively, are recorded as a receivable or payable until the Bitcoin are delivered or removed from the Trust for settlement.

Historical NAV and Bitcoin Prices

As movements in the price of Bitcoin will directly affect the price of the Shares, investors should understand recent movements in the price of Bitcoin. Investors, however, should also be aware that past movements in the Bitcoin 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.

The Trust’s performance prior to January 11, 2024 is based on market-determined prices on the OTCQX marketplace and on the Trust’s performance without an ongoing share creation and redemption program. Prior to January 11, 2024, the Trust’s Shares traded at both premiums and discounts to the value of the Trust’s assets, less its expenses and other liabilities, which at times were substantial, in part due to the lack of an ongoing redemption program. Effective as of January 11, 2024, the Trust established an ongoing share creation and redemption program and the Shares of the Trust were listed to NYSE Arca. Hence, the Trust’s performance for periods prior to January 11, 2024 is not directly comparable to, and should not be used to make conclusions in conjunction with, the Trust’s performance for periods subsequent to January 11, 2024.

The following chart illustrates the movement in the Trust’s NAV per Share (as adjusted for the Share Split for periods prior to January 26, 2018) versus the Index Price and the Trust’s Principal Market NAV per Share (as adjusted for the Share Split for periods prior to January 26, 2018) from September 25, 2013 (the commencement of the Trust’s operations) to March 31, 2026. For more information on the determination of the Trust’s NAV, see “Item 1. Business—Overview of the Bitcoin Industry and Market—Bitcoin Value—The Index and the Index Price” in our Annual Report.

The following table illustrates the movements in the Index Price from April 1, 2021 to March 31, 2026. The Sponsor has not observed a material difference between the Index Price and average prices from the Constituent Trading Platforms as of March 31, 2026, individually or as a group.
