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 provides 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. 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 8 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. Prior to January 11, 2024, the Trust’s Shares had traded on OTC Markets since May 4, 2015. 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. 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 June 30, 2026 and December 31, 2025 and results of operations for the three and six months ended June 30, 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. 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, 9 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. 10 Amount at Fair Value Measurement Using (Amounts in thousands) Fair Value Level 1 Level 2 Level 3 June 30, 2026 Assets Investment in Bitcoin $ 8,136,546 $ 8,136,546 $ - $ - December 31, 2025 Assets Investment in Bitcoin $ 14,497,437 $ 14,497,437 $ - $ - 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. 11 3. Fair Value of Bitcoin Bitcoin is held by the Custodian on behalf of the Trust and is carried at fair value. As of June 30, 2026 and December 31, 2025, the Trust held 138,505.75680424 and 165,591.49612215 Bitcoin, respectively. The Trust determined the fair value per Bitcoin to be $ 58,745.18 and $ 87,549.41 on June 30, 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: (Amounts in thousands, except Bitcoin amounts) Quantity Fair Value Balance at December 31, 2024 205,398.85921873 $ 19,182,244 Bitcoin contributed 3,710.10940106 358,198 Bitcoin redeemed ( 22,569.18287906 ) ( 2,116,013 ) Bitcoin distributed for Sponsor’s Fee, related party ( 1,441.07343529 ) ( 138,276 ) Net change in unrealized appreciation/depreciation on investment in Bitcoin - 769,662 Net realized gain on investment in Bitcoin sold to pay expenses - 116,205 Net realized gain on investment in Bitcoin sold for redemption of Shares - 1,773,097 Balance at June 30, 2025 185,098.71230544 $ 19,945,117 (Amounts in thousands, except Bitcoin amounts) Quantity Fair Value Balance at December 31, 2025 165,591.49612215 $ 14,497,437 Bitcoin contributed 3,514.65852306 263,348 Bitcoin redeemed ( 29,460.89230393 ) ( 2,185,553 ) Bitcoin distributed for Sponsor’s Fee, related party ( 1,139.50553704 ) ( 84,677 ) Net change in unrealized appreciation/depreciation on investment in Bitcoin - ( 6,073,694 ) Net realized gain on investment in Bitcoin sold to pay expenses - 64,069 Net realized gain on investment in Bitcoin sold for redemption of Shares - 1,655,616 Balance at June 30, 2026 138,505.75680424 $ 8,136,546 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 June 30, 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. Three Months Ended June 30, Six Months Ended June 30, 2026 2025 2026 2025 Activity in Number of Shares Issued and Redeemed: Shares issued 820,000 2,210,000 4,510,000 4,690,000 Shares redeemed ( 20,960,000 ) ( 11,890,000 ) ( 37,850,000 ) ( 28,540,000 ) Net Change in Number of Shares Issued and Redeemed ( 20,140,000 ) ( 9,680,000 ) ( 33,340,000 ) ( 23,850,000 ) 12 Three Months Ended June 30, Six Months Ended June 30, (Amounts in thousands) 2026 2025 2026 2025 Activity in Value of Shares Issued and Redeemed: Shares issued $ 39,320 $ 165,628 $ 263,348 $ 358,198 Shares redeemed ( 1,136,936 ) ( 888,832 ) ( 2,185,553 ) ( 2,116,013 ) Net Change in Value of Shares Issued and Redeemed $ ( 1,097,616 ) $ ( 723,204 ) $ ( 1,922,205 ) $ ( 1,757,815 ) Bitcoin receivable represents the value of Bitcoin covered by contractually binding orders for the creation of Shares where the Bitcoin has not yet been transferred to the Trust’s account. Generally, ownership of the Bitcoin is transferred within no more than two business days of the trade date. As of June 30, (Amounts in thousands) 2026 2025 Bitcoin receivable $ - $ - Bitcoin payable represents the value of Bitcoin covered by contractually binding orders for the redemption of Shares where the Bitcoin has not yet been transferred out of the Trust’s account. Generally, ownership of the Bitcoin is transferred within no more than two business days of the trade date. As of June 30, (Amounts in thousands) 2026 2025 Bitcoin payable $ - $ - 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 June 30, 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 June 30, 2026 or December 31, 2025 . 6.

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. 14 8.
