FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains “forward-looking statements” with respect to the financial conditions, results of operations, plans, objectives, future performance and business of Grayscale Bitcoin Trust ETF (the “Trust”). Statements preceded by, followed by or that include words such as “may,” “might,” “will,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” or “continue,” the negative of these terms and other similar expressions are intended to identify some of the forward-looking statements. All statements (other than statements of historical fact) included in this 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 February 27, 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 35.

INDUSTRY AND MARKET DATA

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

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. In general, the Trust holds Bitcoin tokens (“Bitcoin”) and, from time to time, issues common units of fractional undivided beneficial interest (“Shares”) in exchange for Bitcoin. Prior to January 11, 2024, the Trust did not operate a redemption program. On January 10, 2024, the Securities and Exchange Commission (the “SEC”) approved an application under Rule 19b-4 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) by NYSE Arca, Inc. (“NYSE Arca”) to list the Shares of the Trust, which began trading on NYSE Arca on January 11, 2024 (the “Uplisting Date”), following the effectiveness of the Trust’s registration statement on Form S-3, as amended (File No. 333-275079). As of the date of this Quarterly Report, the Trust is an SEC reporting company with its Shares registered pursuant to Section 12(b) of the Exchange Act. On January 10, 2024, in connection with the approval of the 19b-4 Application and the effectiveness of the registration statement on Form S-3, as amended, Grayscale Investments, LLC (“GSI”) authorized the commencement of a redemption program. Effective January 11, 2024, the Trust creates and redeems Shares at such times and for such periods as determined by the Sponsor (as defined below), but only in one or more whole “Baskets.” A Basket equals 10,000 Shares. The creation of a Basket requires the delivery to the Trust of the amount of Bitcoin (or cash to acquire such amount of Bitcoin) represented by one Share immediately prior to such creation multiplied by 10,000. The redemption of a Basket requires distribution by the Trust of the amount of Bitcoin represented by one Share immediately prior to such redemption multiplied by 10,000. The Trust may from time to time halt creations and redemptions for a variety of reasons, including in connection with forks, airdrops and other similar occurrences.

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.

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 7. 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 SEC reporting companies with their shares registered pursuant to Section 12(g) of the Exchange Act. In addition, the following affiliated investment products are also SEC reporting companies with their shares registered pursuant to Section 12(b) of the Exchange Act: 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 redeem Baskets. Grayscale Securities, LLC (“Grayscale Securities” or, in such capacity, an “Authorized Participant”), a registered broker-dealer and affiliate of the Sponsor, was the only Authorized Participant from October 3, 2022 through January 10, 2024. On or after January 10, 2024, the Sponsor, on behalf of the Trust, and the Transfer Agent entered into Participant Agreements with a number of unaffiliated Authorized Participants in connection with the approval of NYSE Arca’s application under Rule 19b-4 of the Exchange Act, and the Trust has also since engaged other Authorized Participants. In connection with the entry into the Participant Agreements, as of January 10, 2024, the Sponsor amended, solely, with respect to the Trust, the Participant Agreement, dated as of October 3, 2022, between the Sponsor and Grayscale Securities, to remove the Trust as an entity covered by the Agreement. Effective January 10, 2024, Grayscale Securities no longer serves as Authorized Participant of the Trust. Additional Authorized Participants may be added at any time, subject to the discretion of the Sponsor.

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, and all transactions will be done on an arm’s-length basis. 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.

Effective January 11, 2024, the Trust, the Sponsor and Coinbase, Inc., the prime broker of the Trust (“Coinbase” or the “Prime Broker”), on behalf of itself and as agent for Coinbase Custody Trust Company, LLC (“Coinbase Custody” or the “Custodian”) and Coinbase Credit, Inc. (“Coinbase Credit” and, collectively with Coinbase and Coinbase Custody, the “Coinbase Entities”), entered into the Coinbase Prime Broker Agreement governing the Trust’s and the Sponsor’s use of the Custodial and Prime Broker Services provided by the Custodian and the Prime Broker. 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, on August 8, 2025, the Sponsor and Anchorage Digital Bank N.A. (“Anchorage Digital”), a national trust bank chartered by the Office of the Comptroller of the Currency, entered into a custodial services agreement (the “Anchorage Digital Custodian Agreement”). Pursuant to the Anchorage Digital Custodian Agreement, Anchorage Digital will provide services related to custody and safekeeping of the Trust’s Bitcoin holdings.

Effective January 11, 2024, 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 Participation 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 10, 2024, the SEC approved an application under Rule 19b-4 of the Exchange Act by NYSE Arca to list the Shares of the Trust. 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, 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. On May 2, 2018 and July 29, 2019, the Sponsor delivered to the former custodian and the current Custodian (as defined below), respectively, on behalf of the Trust, a notice stating that the Trust is abandoning irrevocably for no direct or indirect consideration, effective immediately prior to each time at which the Trust creates Shares, all Incidental Rights and IR Virtual Currency to which it would otherwise be entitled as of such time. On January 5, 2024, the Trust delivered a supplemental notice to the Prime Broker, the Custodian and Coinbase Credit, Inc. providing that the Trust also will abandon irrevocably for no direct or indirect consideration, effective immediately prior to each time at which the Trust redeems Shares, 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 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 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. 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, 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.

The cost basis of the Bitcoin received by the Trust in connection with a creation order is recorded by the Trust at the fair value of Bitcoin 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 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 September 30, 2025 and December 31, 2024, the Trust held 176,564.29142426 and 205,398.85921873 Bitcoin, respectively.

The Trust determined the fair value per Bitcoin to be $114,401.99 on September 30, 2025, 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 Trust determined the fair value per Bitcoin to be $93,390.22 on December 31, 2024, 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 Bitcoin and the respective fair value:

4. The Initial Distribution to the Grayscale Bitcoin Mini Trust ETF

On July 19, 2024, the Sponsor of the Trust at the direction of its board of directors, declared a pro rata distribution on the Shares of the Trust, pursuant to which each holder of Shares as of 4:00 PM ET on July 30, 2024 (the “Record Date”) was entitled to receive shares (the “BTC Shares”) of Grayscale Bitcoin Mini Trust ETF (the “BTC Trust”), a Delaware statutory trust sponsored by the Sponsor, in connection with its previously announced initial creation and distribution of BTC Shares (such transactions collectively, the “Initial Distribution”).

On July 31, 2024, the Trust completed its previously announced pro rata distribution of 303,690,100 shares of the BTC Trust to shareholders of the Trust as of the Record Date and contributed to the BTC Trust an amount of Bitcoin equal to approximately 10% of the total Bitcoin held by the Trust as of the Record Date, equal to 26,935.83753443 Bitcoin with a value of $1,756,821,047, as consideration and in exchange for 303,690,100 shares of the BTC Trust at $5.78 per share.

5. 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 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 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 September 30, 2025 and December 31, 2024.

The cost basis of investments in Bitcoin recorded by the Trust is the fair value of Bitcoin, 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 redeeming Shares as a result of changes in the value of Shares or Bitcoin.

Effective October 28, 2014, the Trust suspended its redemption program, in which shareholders were permitted to request the redemption of their Shares through Genesis, the sole Authorized Participant at the time out of concern that the redemption program was in violation of Regulation M under the Exchange Act, resulting in a settlement reached with the SEC. On October 19, 2021, NYSE Arca filed an application with the SEC pursuant to Rule 19b-4 under the Exchange Act to list the Shares of the Trust on NYSE Arca. On June 29, 2022, the SEC denied NYSE Arca’s 19b-4 application and the Sponsor subsequently petitioned the United States Court of Appeals for the District of Columbia for review of the SEC’s June 29, 2022 final order denying approval to list shares of the Trust on NYSE Arca as an exchange-traded product. On August 29, 2023, the D.C. Circuit Court of Appeals granted the Sponsor’s petition and vacated the SEC’s order, finding that the denial of the Sponsor’s proposal was arbitrary and capricious. The SEC determined not to seek panel rehearing or rehearing en banc. On October 23, 2023, the D.C. Circuit Court of Appeals issued a formal mandate. Ultimately, on January 10, 2024, the SEC approved NYSE Arca’s 19b-4 application to list the Shares of the Trust on NYSE Arca as an exchange-traded product and in connection with the approval of the 19b-4 Application, the Sponsor authorized the commencement of a redemption program.

6. Income Taxes

As of January 1, 2016, an amendment to the Trust Agreement was made to ensure that the Trust Agreement was consistent with the treatment of the Trust as a grantor trust. On February 9, 2017, the Court of Chancery of the State of Delaware ordered that the Original Trust Agreement be reformed so that the amendments made are retroactive to the original date of execution of the Trust Agreement. On September 11, 2017, the Trust received a private letter ruling from the IRS in which the IRS concluded, based on the facts at that time, that the Trust qualified as a grantor trust for U.S. federal income tax purposes as of the date of the private letter ruling.

Accordingly, 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.

7. 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 September 30, 2025 and December 31, 2024, 13,900 and 121,509 Shares of the Trust were held by related parties of the Trust, respectively.

On January 9, 2024, the Sponsor and the Trustee entered into Amendment No. 1 to the Sixth A&R Trust Agreement in order to reduce the Sponsor’s Fee to 1.5%, effective as of the Uplisting Date. As a result, effective January 11, 2024, the Sponsor’s Fee was lowered from 2.0% to 1.5%. 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 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, 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 September 30, 2025 and 2024, the Trust incurred Sponsor’s Fees of $77,959,203 and $55,760,112, respectively. For the nine months ended September 30, 2025 and 2024, the Trust incurred Sponsor’s Fees of $216,234,775 and $222,643,998, 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.

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 Trust 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 September 30, 2022, DCG purchased a total of $771.8 million worth of Shares of the Trust under this authorization. From October 1, 2022 through September 30, 2025, DCG had not purchased any Shares of the Trust under this authorization.

As previously described in Note 4, on July 31, 2024, the Trust completed its previously announced pro rata distribution of 303,690,100 shares of the BTC Trust to shareholders of the Trust as of 4:00 PM ET on the Record Date and contributed to the BTC Trust an amount of Bitcoin equal to approximately 10% of the total Bitcoin held by the Trust as of the Record Date, equal to 26,935.83753443 Bitcoin, as consideration and in exchange for the issuance of shares of the BTC Trust.

8. 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, Bitcoin. Investing in Bitcoin 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 Bitcoin held by the Trust, and fluctuations in the price of Bitcoin could materially and adversely affect an investment in the Shares of the Trust. The price of Bitcoin has a limited history. During such history, Bitcoin 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 Bitcoin, including, but not limited to, global Bitcoin supply and demand, theft of Bitcoin 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 Bitcoin held by the Trust are commingled, and the Trust’s shareholders have no specific rights to any specific Bitcoin. 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 Bitcoin, nor is there a central or major depository for the custody of Bitcoin. There is a risk that some or all of the Trust’s Bitcoin 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 Bitcoin. Further, transactions in Bitcoin are irrevocable. Stolen or incorrectly transferred Bitcoin may be irretrievable. As a result, any incorrectly executed Bitcoin transactions could adversely affect an investment in the Shares.

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 Bitcoin 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 Bitcoin. For example, it may become more difficult for Bitcoin 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 Bitcoin and cause users to migrate to other digital assets. As such, any determination that Bitcoin is a security under federal or state securities laws may adversely affect the value of Bitcoin and, as a result, an investment in the Shares.

In addition, if Bitcoin 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 address on the Bitcoin Network holding Bitcoin is lost, destroyed or otherwise compromised and no backup of the private keys are accessible, the Trust may be unable to access the Bitcoin controlled by the private key and the private key will not be capable of being restored by the Bitcoin Network. The processes by which Bitcoin transactions are settled are dependent on the Bitcoin 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 Bitcoin.

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.

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.

10. 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.

11. 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 Bitcoin determined in accordance with the Trust’s accounting policy was $109,777.00 per Bitcoin.

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 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, as amended (File No. 333-275079), 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, as amended. The Trust issues Shares only in one or more blocks of 10,000 Shares (a block of 10,000 Shares is called a “Basket”) to certain Authorized Participants from time to time. Baskets are offered in exchange for 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.

Historically, the Trust has not met its investment objective and, prior to their uplisting to NYSE Arca on January 11, 2024, the Shares quoted on OTCQX did not reflect the value of the Bitcoin 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 were substantial, although the Sponsor has observed that the Trust has begun to meet its investment objective more closely following the uplisting of the Shares to NYSE Arca.

On 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 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.

•

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.

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 gain on investment in Bitcoin for the three months ended September 30, 2025 was $1,233,506, which includes a realized gain of $66,893 on the transfer of Bitcoin to pay the Sponsor’s Fee, a realized gain of $890,918 on the sale of Bitcoin to meet redemptions, and net change in unrealized appreciation on investment in Bitcoin of $275,695. Net realized and unrealized gain on investment in Bitcoin for the period was driven by Bitcoin price appreciation from $107,753.95 per Bitcoin as of June 30, 2025, to $114,401.99 per Bitcoin as of September 30, 2025.

Net assets increased to $20,199,306 at September 30, 2025, a 1% increase for the three-month period. The increase in net assets resulted from the aforementioned Bitcoin price appreciation and the contribution of approximately 1,187 Bitcoin with a value of $135,529 to the Trust in connection with Share creations during the period, partially offset by the withdrawal of approximately 682 Bitcoin to pay the foregoing Sponsor’s Fee, and the redemption of approximately 9,040 Bitcoin, with a value of $1,036,887 from the Trust.

Net realized and unrealized gain on investment in Bitcoin for the three months ended September 30, 2024 was $375,299, which includes a realized gain of $43,615 on the transfer of Bitcoin to pay the Sponsor’s Fee, a realized gain of $1,350,850 on the sale of Bitcoin to meet redemptions, a realized gain of $1,410,878 on the sale of Bitcoin related to the Initial Distribution to Grayscale Bitcoin Mini Trust ETF, and net change in unrealized appreciation on investment in Bitcoin of ($2,430,044).

Net increase in net assets resulting from operations was $319,538 for the three months ended September 30, 2024, which consisted of the net realized and unrealized gain on investment in Bitcoin, less the Sponsor’s Fee of $55,761. Net assets decreased to $14,037,855 at September 30, 2024, an 18% decrease for the three-month period. The decrease in net assets resulted from the withdrawal of approximately 913 Bitcoin to pay the foregoing Sponsor’s Fee, the redemption of approximately 28,572 Bitcoin, with a value of $1,717,011 from the Trust, and the Initial Distribution of approximately 26,936 Bitcoin, with a value of $1,756,821 from the Trust to Grayscale Bitcoin Mini Trust ETF, partially offset by the aforementioned Bitcoin price appreciation and the contribution of approximately 1,877 Bitcoin with a value of $116,077 to the Trust in connection with Share creations during the period.

Net realized and unrealized gain on investment in Bitcoin for the nine months ended September 30, 2025 was $3,892,470, which includes a realized gain of $183,098 on the transfer of Bitcoin to pay the Sponsor’s Fee, a realized gain of $2,664,015 on the sale of Bitcoin to meet redemptions, and net change in unrealized appreciation on investment in Bitcoin of $1,045,357.

Net assets increased to $20,199,306 at September 30, 2025, a 5% increase for the nine-month period. The increase in net assets resulted from the aforementioned Bitcoin price appreciation and the contribution of approximately 4,897 Bitcoin with a value of $493,727 to the Trust in connection with Share creations during the period, partially offset by the withdrawal of approximately 2,123 Bitcoin to pay the foregoing Sponsor’s Fee, and the redemption of approximately 31,609 Bitcoin, with a value of $3,152,900 from the Trust.

Net assets decreased to $14,037,855 at September 30, 2024, a 47% decrease for the nine-month period. The decrease in net assets resulted from the withdrawal of approximately 3,854 Bitcoin to pay the foregoing Sponsor’s Fee, the redemption of approximately 374,462 Bitcoin, with a value of $20,547,134 from the Trust, and the Initial Distribution of approximately 26,936 Bitcoin, with a value of $1,756,821 from the Trust to Grayscale Bitcoin Mini Trust ETF, partially offset by the aforementioned Bitcoin price appreciation and the contribution of approximately 6,917 Bitcoin with a value of $440,584 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.

As of September 30, 2025, the Principal Market NAV per Share was calculated using the fair value of Bitcoin based on the price provided by Crypto.com, 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. As of September 30, 2024, the Principal Market NAV per Share was calculated using the fair value of Bitcoin based on the price provided by Coinbase, 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. Prior to December 26, 2023, Principal Market NAV was referred to as NAV and Principal Market NAV per Share was referred to as NAV per Share.

(4)

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. The Trust’s NAV per Share is calculated using a non-GAAP methodology where the price is derived from multiple Digital Asset Trading Platforms. Prior to December 26, 2023, NAV was referred to as Digital Asset Holdings and NAV per Share was referred to as Digital Asset Holdings per Share. 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 Digital Asset Trading Platforms included in the Index (the “Constituent Trading Platforms”) as of September 30, 2025 were Coinbase, Bitstamp by Robinhood, Kraken, LMAX Digital, Crypto.com, Bitfinex and Bullish. The Digital Asset Trading Platforms included in the Index as of September 30, 2024 were Coinbase, Bitstamp by Robinhood, Kraken, LMAX Digital and Crypto.com. See “Item 1. Business—Valuation of Bitcoin and Determination of NAV” in our Annual Report for a description of the Trust’s NAV per Share.

For accounting purposes prior to January 11, 2024, the Trust reflected creations and the Bitcoin receivable for proceeds with respect to such creations on the date of receipt of a notification of a creation but did not issue Shares until the requisite amount of Bitcoin for proceeds was received. 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, as amended, the Sponsor authorized the commencement of a redemption program. Effective January 11, 2024, the date on which the Shares of the Trust began trading on NYSE Arca, the Trust reflects creations and redemptions and the Bitcoin for proceeds receivable or payable with respect to such creations and redemptions, respectively, on the business day following the receipt of a notification of a creation or redemption order 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.

As of September 30, 2025, the Trust had a net closing balance of 176,564.29142426 Bitcoin with a value of $20,198,879,016 based on the Index Price of $114,399.57 on September 30, 2025 (non-GAAP methodology).

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 (date of the first Creation Basket of the Trust) to September 30, 2025.
