GRAYSCALE ZCASH TRUST (ZEC)

NOTES TO THE UNAUDITED FINANCIAL STATEMENTS

1. Organization

Grayscale Zcash Trust (ZEC) (the “Trust”) is a Delaware Statutory Trust that was formed on October 23, 2017 and commenced operations on October 24, 2017. In general, the Trust holds Zcash (“ZEC”) and, from time to time, issues common units of fractional undivided beneficial interest (“Shares”) (in minimum baskets of 100 Shares, referred to as “Baskets”) in exchange for ZEC. As of March 31, 2026, the Trust did not operate a redemption program. Subject to receipt of regulatory approval and approval by the Sponsor in its sole discretion, the Trust may in the future operate a redemption program. The Trust’s investment objective is for the value of the Shares (based on ZEC per Share) to reflect the value of the ZEC held by the Trust, less the Trust’s expenses and other liabilities.

Grayscale Investments, LLC (“GSI”) was the sponsor of the Trust before January 1, 2025, Grayscale Operating, LLC (“GSO”) was the co-sponsor of the Trust from January 1, 2025 to May 3, 2025, and Grayscale Investments Sponsors, LLC (“GSIS,” or the “Sponsor”) was the co-sponsor of the Trust from January 1, 2025 to May 3, 2025 and is the sole remaining sponsor thereafter. GSI was, and each of GSO and GSIS are, a consolidated subsidiary of Digital Currency Group, Inc. (“DCG”). The Sponsor is responsible for the day-to-day administration of the Trust pursuant to the provisions of the Trust Agreement. The Sponsor is responsible for preparing and providing annual and quarterly reports on behalf of the Trust to investors and is also responsible for selecting and monitoring the Trust’s service providers. As partial consideration for the Sponsor’s services, the Trust pays the Sponsor a Sponsor’s Fee as discussed in Note 6. The Sponsor also acts as the sponsor and manager of other single-asset and diversified investment products, each of which is an affiliate of the Trust. Information related to the affiliated investment products can be found on the Sponsor’s website at www.grayscale.com/resources/regulatory-filings. Any information contained on or linked from such website is not part of nor incorporated by reference into these unaudited financial statements.

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

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

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

On October 18, 2021, the Trust received notice that its Shares were qualified for public trading on the OTCQX Best Market® (“OTCQX”) of OTC Markets Group Inc. The Trust’s trading symbol on OTCQX is “ZCSH” and the CUSIP number for its Shares is 38964G108.

The Trust may also receive Incidental Rights and/or IR Virtual Currency as a result of the Trust’s investment in ZEC, 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 ZEC and arise without any action of the Trust, or of the Sponsor or Trustee on behalf of the Trust; IR Virtual Currency is any virtual currency tokens, or other asset or right, received by the Trust through the exercise (subject to the applicable provisions of the Trust Agreement) of any Incidental Right.

2. Summary of Significant Accounting Policies

In the opinion of management of the Sponsor of the Trust, all adjustments (which include normal recurring adjustments) necessary to present fairly the financial position as of March 31, 2026 and December 31, 2025 and results of operations for the three months ended March 31, 2026 and 2025 have been made. The results of operations for the periods presented are not necessarily indicative of the results of operations expected for the full year. These unaudited financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2025 included in our Annual Report.

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

The financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). The Trust qualifies as an investment company for accounting purposes pursuant to the accounting and reporting guidance under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, Financial Services—Investment Companies. The Trust uses fair value as its method of accounting for ZEC 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 ZEC, including receiving ZEC for the creation of Shares and delivering ZEC for the redemption of Shares and for the payment of the Sponsor’s Fee. At this time, the Trust is not accepting redemption requests from shareholders. Since its inception, the Trust has not held cash or cash equivalents. The Sponsor will determine the Trust’s net asset value (“NAV”) on each business day as of 4:00 p.m., New York time, or as soon thereafter as practicable.

Principal Market and Fair Value Determination

To determine which market is the Trust’s principal market (or in the absence of a principal market, the most advantageous market) for purposes of calculating the Trust’s net asset value in accordance with U.S. GAAP (“Principal Market NAV”), the Trust follows ASC Topic 820-10, Fair Value Measurement, which outlines the application of fair value accounting. ASC 820-10 determines fair value to be the price that would be received for ZEC 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 ZEC 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 ZEC 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 ZEC 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 ZEC for Share creations and the delivery of ZEC for Share redemptions or for payment of expenses in ZEC. At this time, the Trust is not accepting redemption requests from shareholders. The Trust records its investment transactions on a trade date basis and changes in fair value are reflected as net change in unrealized appreciation or depreciation on investments. Realized gains and losses are calculated using the specific identification method. Realized gains and losses are recognized in connection with transactions including settling obligations for the Sponsor’s Fee in ZEC.

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 ZEC

ZEC is held by the Custodian on behalf of the Trust and is carried at fair value. As of March 31, 2026 and December 31, 2025, the Trust held 391,103.88769118 and 393,522.33134026 ZEC, respectively.

The Trust determined the fair value per ZEC to be $254.27 and $509.35 on March 31, 2026 and December 31, 2025, respectively, using the price provided at 4:00 p.m., New York time, by the Digital Asset Trading Platform Market considered to be the Trust’s principal market (Coinbase).

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

(Amounts in thousands, except ZEC amounts)	Quantity			Fair Value
Balance at December 31, 2024		392,723.58934327		$	22,040
ZEC contributed		4,888.23272520			191
ZEC distributed for Sponsor’s Fee, related party		(2,427.56268494	)		(96	)

Net realized gain on investment in ZEC		-			425
Balance at March 31, 2026		391,103.88769118		$	99,446

4. Creations and Redemptions of Shares

The Trust creates (and, should the Trust commence a redemption program, redeems) Shares from time to time, but only in one or more Baskets issued to the Authorized Participant in exchange for the delivery of ZEC to the Trust or the distribution of ZEC by the Trust. The amount of ZEC required for each Creation Basket or redemption Basket is determined by dividing (x) the amount of ZEC 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 ZEC representing the U.S. dollar value of accrued but unpaid fees and expenses of the Trust, by (y) the number of Shares outstanding at such time and multiplying the quotient obtained by 100. Each Share represented approximately 0.0810 and 0.0815 of one ZEC at March 31, 2026 and December 31, 2025, respectively. The decrease in the amount of ZEC represented by each Share is primarily a result of the periodic withdrawal of ZEC to pay the Sponsor’s Fee.

At this time, the Trust is not operating a redemption program and is not accepting redemption requests. Subject to receipt of regulatory approval and approval by the Sponsor in its sole discretion, the Trust may in the future operate a redemption program.

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

11

ended March 31, 2026 and December 31, 2025, the Trust did not have a liability for any unrecognized tax amounts. However, the Sponsor’s conclusions concerning its determination of “more-likely-than-not” tax positions may be subject to review and adjustment at a later date based on factors including, but not limited to, further implementation guidance, and ongoing analyses of and changes to tax laws, regulations and interpretations thereof.

The Sponsor of the Trust has evaluated whether or not there are uncertain tax positions that require financial statement recognition and has determined that no reserves for uncertain tax positions related to federal, state and local income taxes existed as of March 31, 2026 or December 31, 2025.

6. Related Parties

The Trust considered the following entities, their directors, and certain employees to be related parties of the Trust as of March 31, 2026: DCG, GSO, GSIS, and Grayscale Securities. As of March 31, 2026 and December 31, 2025, 749,481 and 713,306 Shares of the Trust were held by related parties of the Trust, respectively.

In accordance with the Trust Agreement governing the Trust, the Trust pays a fee to the Sponsor, calculated as 2.5% of the aggregate value of the Trust’s assets, less its liabilities (which include any accrued but unpaid expenses up to, but excluding, the date of calculation), as calculated and published by the Sponsor or its delegates in the manner set forth in the Trust Agreement (the “Sponsor’s Fee”). The Sponsor’s Fee accrues daily in U.S. dollars and is payable in ZEC, monthly in arrears. The amount of ZEC payable in respect of each daily U.S. dollar accrual will be determined by reference to the same U.S. dollar value of ZEC used to determine such accrual. For purposes of these financial statements, the U.S. dollar value of ZEC is determined by reference to the Digital Asset Trading Platform Market that the Trust considers its principal market as of 4:00 p.m., New York time, on each valuation date. The Trust held no Incidental Rights or IR Virtual Currency as of March 31, 2026 and December 31, 2025. No Incidental Rights or IR Virtual Currencies have been distributed in payment of the Sponsor’s Fee during the three months ended March 31, 2026 and 2025.

As partial consideration for receipt of the Sponsor’s Fee, the Sponsor is obligated under the Trust Agreement to assume and pay all fees and other expenses incurred by the Trust in the ordinary course of its affairs, excluding taxes, but including marketing fees; administrator fees, if any; custodian fees; transfer agent fees; trustee fees; the fees and expenses related to the listing, quotation or trading of the Shares on any secondary market (including customary legal, marketing and audit fees and expenses) in an amount up to $600,000 in any given fiscal year; ordinary course legal fees and expenses; audit fees; regulatory fees, including, if applicable, any fees relating to the registration of the Shares under the Securities Act or the Exchange Act; printing and mailing costs; the costs of maintaining the Trust’s website and applicable license fees (together, the “Sponsor-paid Expenses”), provided that any expense that qualifies as an Additional Trust Expense will be deemed to be an Additional Trust Expense and not a Sponsor-paid Expense.

The Trust may incur certain extraordinary, non-recurring expenses that are not Sponsor-paid Expenses, including, but not limited to, taxes and governmental charges, expenses and costs of any extraordinary services performed by the Sponsor (or any other service provider) on behalf of the Trust to protect the Trust or the interests of shareholders (including in connection with any Incidental Rights and any IR Virtual Currency), any indemnification of the Custodian or other agents, service providers or counterparties of the Trust, the fees and expenses related to the listing, quotation or trading of the Shares on any secondary market (including legal, marketing and audit fees and expenses) to the extent exceeding $600,000 in any given fiscal year and extraordinary legal fees and expenses, including any legal fees and expenses incurred in connection with litigation, regulatory enforcement or investigation matters (collectively “Additional Trust Expenses”). In such circumstances, the Sponsor or its delegate (i) will instruct the Custodian to withdraw from the Digital Asset Account ZEC, Incidental Rights and/or IR Virtual Currency in such quantity as may be necessary to permit payment of such Additional Trust Expenses and (ii) may either (x) cause the Trust (or its delegate) to convert such ZEC, Incidental Rights and/or IR Virtual Currency into U.S. dollars or other fiat currencies at the Actual Exchange Rate or (y) when the Sponsor incurs such expenses on behalf of the Trust, cause the Trust (or its delegate) to deliver such ZEC, Incidental Rights and/or IR Virtual Currency in kind to the Sponsor, in each case in such quantity as may be necessary to permit payment of such Additional Trust Expenses.

For the three months ended March 31, 2026 and 2025, the Trust incurred Sponsor’s Fees of $719,633 and $96,512, respectively. As of March 31, 2026 and December 31, 2025, there were no accrued and unpaid Sponsor’s Fees. In addition, the Sponsor may pay Additional Trust Expenses on behalf of the Trust, which are reimbursable by the Trust to the Sponsor. For the three months ended March 31, 2026 and 2025, the Sponsor did not pay any Additional Trust Expenses on behalf of the Trust.

On March 2, 2022, the Board of the Sponsor approved the purchase by DCG, the indirect parent company of the Sponsor, of up to $10 million worth of Shares of the Trust. Subsequently, DCG authorized such purchase. 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 2, 2022 through June 30, 2022, DCG purchased a total of $2.0 million worth of Shares of the Trust. From July 1, 2022 through March 31, 2026, DCG had not purchased any Shares of the Trust under this authorization.

7. Concentration Risk

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

8. Financial Highlights Per Share Performance

	Three Months Ended March 31,
	2026			2025
Per Share Data:
Principal Market NAV, beginning of period	$	41.51		$	4.69
Net decrease in net assets from investment operations:
Net investment loss		(0.15	)		(0.02	)
Net realized and unrealized loss		(20.77	)		(1.51	)
Net decrease in net assets resulting from operations		(20.92	)		(1.53	)
Principal Market NAV, end of period	$	20.59		$	3.16
Total return		-50.40	%		-32.62	%
Ratios to average net assets:
Net investment loss		-2.50	%		-2.50	%
Expenses		-2.50	%		-2.50	%

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

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

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

9. Indemnifications

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

10. Subsequent Events

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

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

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

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read together with, and is qualified in its entirety by reference to, our unaudited financial statements and related notes included elsewhere in this Quarterly Report, which have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). The following discussion may contain forward-looking statements based on assumptions we believe to be reasonable. Our actual results could differ materially from those discussed in these forward-looking statements. Factors that could cause or contribute to these differences include, but are not limited to, those set forth under “Part II, Item 1A. Risk Factors” in this Quarterly Report, or in “Part I, Item 1A. Risk Factors” and “Forward-Looking Statements” or other sections of our Annual Report.

Trust Overview

The Trust is a passive entity that is managed and administered by the Sponsor and does not have any officers, directors or employees. The Trust holds ZEC and, from time to time on a periodic basis, issues Creation Baskets in exchange for deposits of ZEC. As a passive investment vehicle, the Trust’s investment objective is for the value of the Shares (based on ZEC per Share) to reflect the value of the ZEC 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 ZEC, the Shares are designed to provide investors with a cost-effective and convenient way to gain investment exposure to ZEC. To date, the Trust has not met its investment objective and the Shares quoted on OTCQX have not reflected the value of the ZEC held by the Trust, less the Trust’s expenses and other liabilities, but instead have traded at both premiums and discounts to such value, which at times have been substantial. The Trust is not managed like a business corporation or an active investment vehicle. The Trust will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective.

Prior to April 1, 2026, the Trust valued the ZEC held by the Trust for operational purposes by reference to the CoinDesk Zcash Price Index (ZCX). As of April 1, 2026, the Index is the CoinDesk Zcash Benchmark Rate which is used to calculate the NAV and NAV per Share. Prior to April 1, 2026, references to the “Index” in the Trust’s filings with the SEC, including this Quarterly Report on Form 10-Q, refer to the CoinDesk Zcash Price Index (ZCX). From and after April 1, 2026, references to the “Index” in the Trust’s filings with the SEC are to the CoinDesk Zcash Benchmark Rate.

Critical Accounting Policies and Estimates

Investment Transactions and Revenue Recognition

The Trust considers investment transactions to be the receipt of ZEC by the Trust in connection with Share creations and the delivery of ZEC by the Trust in connection with Share redemptions or for payment of expenses in ZEC. At this time, the Trust is not accepting redemption requests from shareholders. The Trust records its investment transactions on a trade date basis and changes in fair value are reflected as net change in unrealized appreciation or depreciation on investments. Realized gains and losses are calculated using the specific identification method. Realized gains and losses are recognized in connection with transactions including settling obligations for the Sponsor’s Fee in ZEC.

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 ZEC 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 ZEC 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 ZEC 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

14

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 ZEC 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 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 ZEC in accordance with its classification as an investment company for accounting purposes. The Trust is not a registered investment company under the Investment Company Act. U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates and these differences could be material.

Review of Financial Results (unaudited)

Financial Highlights for the Three Months Ended March 31, 2026 and 2025

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

	Three Months Ended March 31,
	2026			2025
Net realized and unrealized loss on investment in ZEC	$	(100,275	)	$	(7,086	)
Net decrease in net assets resulting from operations	$	(100,995	)	$	(7,182	)
Net assets(1)	$	99,446		$	15,049

(1)Net assets in the above table and subsequent paragraphs are calculated in accordance with U.S. GAAP based on the Digital Asset Market price of ZEC on the Digital Asset Trading Platform that the Trust considered its principal market, as of 4:00 p.m., New York time, on the valuation date.

Net realized and unrealized loss on investment in ZEC for the three months ended March 31, 2026 was ($100,275), which includes a realized gain of $425 on the transfer of ZEC to pay the Sponsor’s Fee and net change in unrealized appreciation/depreciation on investment in ZEC of ($100,700). Net realized and unrealized loss on investment in ZEC for the period was driven by ZEC price depreciation from $509.35 per ZEC as of December 31, 2025, to $254.27 per ZEC as of March 31, 2026. Net decrease in net assets resulting from operations was ($100,995) for the three months ended March 31, 2026, which consisted of the net realized and unrealized loss on investment in ZEC, plus the Sponsor’s Fee of $720. Net assets decreased to $99,446 at March 31, 2026, a 50% decrease for the three-month period. The decrease in net assets resulted from the aforementioned ZEC price depreciation and the withdrawal of approximately 2,418 ZEC to pay the foregoing Sponsor’s Fee.

Net realized and unrealized loss on investment in ZEC for the three months ended March 31, 2025 was ($7,086), which includes a realized loss of ($202) on the transfer of ZEC to pay the Sponsor’s Fee and net change in unrealized appreciation/depreciation on investment in ZEC of ($6,884). Net realized and unrealized loss on investment in ZEC for the period was driven by ZEC price depreciation from $56.12 per ZEC as of December 31, 2024, to $38.08 per ZEC as of March 31, 2025. Net decrease in net assets resulting from operations was ($7,182) for the three months ended March 31, 2025, which consisted of the net realized and unrealized loss on investment in ZEC, plus the Sponsor’s Fee of $96. Net assets decreased to $15,049 at March 31, 2025, a 32% decrease for the three-month period. The decrease in net assets resulted from the aforementioned ZEC price depreciation and the withdrawal of approximately

15

2,428 ZEC to pay the foregoing Sponsor’s Fee, partially offset by the contribution of approximately 4,888 ZEC with a value of $191 to the Trust in connection with Share creations during the period.

Cash Resources and Liquidity

The Trust has not had a cash balance at any time since inception. When selling ZEC, Incidental Rights and/or IR Virtual Currency in the Digital Asset Market to pay Additional Trust Expenses on behalf of the Trust, the Sponsor endeavors to sell the exact amount of ZEC, Incidental Rights and/or IR Virtual Currency needed to pay expenses in order to minimize the Trust’s holdings of assets other than ZEC. As a consequence, the Sponsor expects that the Trust will not record any cash flow from its operations and that its cash balance will be zero at the end of each reporting period. Furthermore, the Trust is not a party to any off-balance sheet arrangements.

In exchange for the Sponsor’s Fee, the Sponsor has agreed to assume most of the expenses incurred by the Trust. As a result, the only ordinary expense of the Trust during the periods covered by this Quarterly Report was the Sponsor’s Fee. The Trust is not aware of any trends, demands, conditions or events that are reasonably likely to result in material changes to its liquidity needs.

Selected Operating Data

	As of March 31,
	2026		2025
Price of ZEC on principal market	$	254.27	$	38.08
Principal Market NAV per Share(1)	$	20.59	$	3.16

Index Price	$	254.35	$	38.08
NAV per Share(2)	$	20.60	$	3.16
NAV(2)	$	99,477,274	$	15,048,617

(1)The Principal Market NAV and Principal Market NAV per Share are calculated using the fair value of ZEC based on the price provided by the Digital Asset Trading Platform that the Trust considered its principal market, as of 4:00 p.m., New York time, on the valuation date, in accordance with U.S. GAAP.

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

For accounting purposes, the Trust reflects creations and the ZEC receivable with respect to such creations on the date of receipt of a notification of a creation but does not issue Shares until the requisite amount of ZEC is received. At this time, the Trust is not accepting redemption requests from shareholders. Subject to receipt of regulatory approval from the SEC and approval by the Sponsor in its sole discretion, the Trust may in the future operate a redemption program.

Historical NAV and ZEC Prices

As movements in the price of ZEC will directly affect the price of the Shares, investors should understand recent movements in the price of ZEC. Investors, however, should also be aware that past movements in the ZEC 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 following chart illustrates the movement in the Trust’s NAV per Share versus the Index Price and the Trust’s Principal Market NAV per Share from October 24, 2017 (the inception of the Trust’s operations) to March 31, 2026. For more information on the determination of the Trust’s NAV, see “Item 1. Business—Overview of the ZEC Industry and Market—ZEC Value—The Index and the Index Price” in our Annual Report.

Organization

1. Organization

Grayscale Zcash Trust (ZEC) (the “Trust”) is a Delaware Statutory Trust that was formed on October 23, 2017 and commenced operations on October 24, 2017. In general, the Trust holds Zcash (“ZEC”) and, from time to time, issues common units of fractional undivided beneficial interest (“Shares”) (in minimum baskets of 100 Shares, referred to as “Baskets”) in exchange for ZEC. As of March 31, 2026, the Trust did not operate a redemption program. Subject to receipt of regulatory approval and approval by the Sponsor in its sole discretion, the Trust may in the future operate a redemption program. The Trust’s investment objective is for the value of the Shares (based on ZEC per Share) to reflect the value of the ZEC held by the Trust, less the Trust’s expenses and other liabilities.

Grayscale Investments, LLC (“GSI”) was the sponsor of the Trust before January 1, 2025, Grayscale Operating, LLC (“GSO”) was the co-sponsor of the Trust from January 1, 2025 to May 3, 2025, and Grayscale Investments Sponsors, LLC (“GSIS,” or the “Sponsor”) was the co-sponsor of the Trust from January 1, 2025 to May 3, 2025 and is the sole remaining sponsor thereafter. GSI was, and each of GSO and GSIS are, a consolidated subsidiary of Digital Currency Group, Inc. (“DCG”). The Sponsor is responsible for the day-to-day administration of the Trust pursuant to the provisions of the Trust Agreement. The Sponsor is responsible for preparing and providing annual and quarterly reports on behalf of the Trust to investors and is also responsible for selecting and monitoring the Trust’s service providers. As partial consideration for the Sponsor’s services, the Trust pays the Sponsor a Sponsor’s Fee as discussed in Note 6. The Sponsor also acts as the sponsor and manager of other single-asset and diversified investment products, each of which is an affiliate of the Trust. Information related to the affiliated investment products can be found on the Sponsor’s website at www.grayscale.com/resources/regulatory-filings. Any information contained on or linked from such website is not part of nor incorporated by reference into these unaudited financial statements.

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

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

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

On October 18, 2021, the Trust received notice that its Shares were qualified for public trading on the OTCQX Best Market® (“OTCQX”) of OTC Markets Group Inc. The Trust’s trading symbol on OTCQX is “ZCSH” and the CUSIP number for its Shares is 38964G108.

The Trust may also receive Incidental Rights and/or IR Virtual Currency as a result of the Trust’s investment in ZEC, 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 ZEC 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.

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

In the opinion of management of the Sponsor of the Trust, all adjustments (which include normal recurring adjustments) necessary to present fairly the financial position as of March 31, 2026 and December 31, 2025 and results of operations for the three months ended March 31, 2026 and 2025 have been made. The results of operations for the periods presented are not necessarily indicative of the results of operations expected for the full year. These unaudited financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2025 included in our Annual Report.

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

The financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). The Trust qualifies as an investment company for accounting purposes pursuant to the accounting and reporting guidance under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, Financial Services—Investment Companies. The Trust uses fair value as its method of accounting for ZEC 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 ZEC, including receiving ZEC for the creation of Shares and delivering ZEC for the redemption of Shares and for the payment of the Sponsor’s Fee. At this time, the Trust is not accepting redemption requests from shareholders. Since its inception, the Trust has not held cash or cash equivalents. The Sponsor will determine the Trust’s net asset value (“NAV”) on each business day as of 4:00 p.m., New York time, or as soon thereafter as practicable.

Principal Market and Fair Value Determination

To determine which market is the Trust’s principal market (or in the absence of a principal market, the most advantageous market) for purposes of calculating the Trust’s net asset value in accordance with U.S. GAAP (“Principal Market NAV”), the Trust follows ASC Topic 820-10, Fair Value Measurement, which outlines the application of fair value accounting. ASC 820-10 determines fair value to be the price that would be received for ZEC 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 ZEC 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 ZEC 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 ZEC 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 ZEC for Share creations and the delivery of ZEC for Share redemptions or for payment of expenses in ZEC. At this time, the Trust is not accepting redemption requests from shareholders. The Trust records its investment transactions on a trade date basis and changes in fair value are reflected as net change in unrealized appreciation or depreciation on investments. Realized gains and losses are calculated using the specific identification method. Realized gains and losses are recognized in connection with transactions including settling obligations for the Sponsor’s Fee in ZEC.

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.

Fair Value of ZEC

3. Fair Value of ZEC

ZEC is held by the Custodian on behalf of the Trust and is carried at fair value. As of March 31, 2026 and December 31, 2025, the Trust held 391,103.88769118 and 393,522.33134026 ZEC, respectively.

The Trust determined the fair value per ZEC to be $254.27 and $509.35 on March 31, 2026 and December 31, 2025, respectively, using the price provided at 4:00 p.m., New York time, by the Digital Asset Trading Platform Market considered to be the Trust’s principal market (Coinbase).

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

Creations and Redemptions of Shares

4. Creations and Redemptions of Shares

The Trust creates (and, should the Trust commence a redemption program, redeems) Shares from time to time, but only in one or more Baskets issued to the Authorized Participant in exchange for the delivery of ZEC to the Trust or the distribution of ZEC by the Trust. The amount of ZEC required for each Creation Basket or redemption Basket is determined by dividing (x) the amount of ZEC 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 ZEC representing the U.S. dollar value of accrued but unpaid fees and expenses of the Trust, by (y) the number of Shares outstanding at such time and multiplying the quotient obtained by 100. Each Share represented approximately 0.0810 and 0.0815 of one ZEC at March 31, 2026 and December 31, 2025, respectively. The decrease in the amount of ZEC represented by each Share is primarily a result of the periodic withdrawal of ZEC to pay the Sponsor’s Fee.

At this time, the Trust is not operating a redemption program and is not accepting redemption requests. Subject to receipt of regulatory approval and approval by the Sponsor in its sole discretion, the Trust may in the future operate a redemption program.

Income Tax Disclosure [Abstract]

Income Taxes

5. Income Taxes

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

If the Trust were not properly classified as a grantor trust, the Trust might be classified as a partnership for U.S. federal income tax purposes. However, due to the uncertain treatment of digital assets, including forks, airdrops and similar occurrences for U.S. federal income tax purposes, there can be no assurance in this regard. If the Trust were classified as a partnership for U.S. federal income tax purposes, the tax consequences of owning Shares generally would not be materially different from the tax consequences described herein, although there might be certain differences, including with respect to timing. In addition, tax information reports provided to beneficial owners of Shares would be made in a different form. If the Trust were not classified as either a grantor trust or a partnership for U.S. federal income tax purposes, it would be classified as a corporation for such purposes. In that event, the Trust would be subject to entity-level U.S. federal income tax (currently at the rate of 21%) on its net taxable income and certain distributions made by the Trust to shareholders would be treated as taxable dividends to the extent of the Trust’s current and accumulated earnings and profits.

In accordance with U.S. GAAP, the Trust has defined the threshold for recognizing the benefits of tax positions in the financial statements as “more-likely-than-not” to be sustained by the applicable taxing authority and requires measurement of a tax position meeting the “more-likely-than-not” threshold, based on the largest benefit that is more than 50% likely to be realized. Tax positions deemed to meet the “more-likely-than-not” threshold are recorded as a tax benefit in the current period. As of, and during the periods

ended March 31, 2026 and December 31, 2025, the Trust did not have a liability for any unrecognized tax amounts. However, the Sponsor’s conclusions concerning its determination of “more-likely-than-not” tax positions may be subject to review and adjustment at a later date based on factors including, but not limited to, further implementation guidance, and ongoing analyses of and changes to tax laws, regulations and interpretations thereof.

The Sponsor of the Trust has evaluated whether or not there are uncertain tax positions that require financial statement recognition and has determined that no reserves for uncertain tax positions related to federal, state and local income taxes existed as of March 31, 2026 or December 31, 2025.

6. Related Parties

The Trust considered the following entities, their directors, and certain employees to be related parties of the Trust as of March 31, 2026: DCG, GSO, GSIS, and Grayscale Securities. As of March 31, 2026 and December 31, 2025, 749,481 and 713,306 Shares of the Trust were held by related parties of the Trust, respectively.

In accordance with the Trust Agreement governing the Trust, the Trust pays a fee to the Sponsor, calculated as 2.5% of the aggregate value of the Trust’s assets, less its liabilities (which include any accrued but unpaid expenses up to, but excluding, the date of calculation), as calculated and published by the Sponsor or its delegates in the manner set forth in the Trust Agreement (the “Sponsor’s Fee”). The Sponsor’s Fee accrues daily in U.S. dollars and is payable in ZEC, monthly in arrears. The amount of ZEC payable in respect of each daily U.S. dollar accrual will be determined by reference to the same U.S. dollar value of ZEC used to determine such accrual. For purposes of these financial statements, the U.S. dollar value of ZEC is determined by reference to the Digital Asset Trading Platform Market that the Trust considers its principal market as of 4:00 p.m., New York time, on each valuation date. The Trust held no Incidental Rights or IR Virtual Currency as of March 31, 2026 and December 31, 2025. No Incidental Rights or IR Virtual Currencies have been distributed in payment of the Sponsor’s Fee during the three months ended March 31, 2026 and 2025.

As partial consideration for receipt of the Sponsor’s Fee, the Sponsor is obligated under the Trust Agreement to assume and pay all fees and other expenses incurred by the Trust in the ordinary course of its affairs, excluding taxes, but including marketing fees; administrator fees, if any; custodian fees; transfer agent fees; trustee fees; the fees and expenses related to the listing, quotation or trading of the Shares on any secondary market (including customary legal, marketing and audit fees and expenses) in an amount up to $600,000 in any given fiscal year; ordinary course legal fees and expenses; audit fees; regulatory fees, including, if applicable, any fees relating to the registration of the Shares under the Securities Act or the Exchange Act; printing and mailing costs; the costs of maintaining the Trust’s website and applicable license fees (together, the “Sponsor-paid Expenses”), provided that any expense that qualifies as an Additional Trust Expense will be deemed to be an Additional Trust Expense and not a Sponsor-paid Expense.

The Trust may incur certain extraordinary, non-recurring expenses that are not Sponsor-paid Expenses, including, but not limited to, taxes and governmental charges, expenses and costs of any extraordinary services performed by the Sponsor (or any other service provider) on behalf of the Trust to protect the Trust or the interests of shareholders (including in connection with any Incidental Rights and any IR Virtual Currency), any indemnification of the Custodian or other agents, service providers or counterparties of the Trust, the fees and expenses related to the listing, quotation or trading of the Shares on any secondary market (including legal, marketing and audit fees and expenses) to the extent exceeding $600,000 in any given fiscal year and extraordinary legal fees and expenses, including any legal fees and expenses incurred in connection with litigation, regulatory enforcement or investigation matters (collectively “Additional Trust Expenses”). In such circumstances, the Sponsor or its delegate (i) will instruct the Custodian to withdraw from the Digital Asset Account ZEC, Incidental Rights and/or IR Virtual Currency in such quantity as may be necessary to permit payment of such Additional Trust Expenses and (ii) may either (x) cause the Trust (or its delegate) to convert such ZEC, Incidental Rights and/or IR Virtual Currency into U.S. dollars or other fiat currencies at the Actual Exchange Rate or (y) when the Sponsor incurs such expenses on behalf of the Trust, cause the Trust (or its delegate) to deliver such ZEC, Incidental Rights and/or IR Virtual Currency in kind to the Sponsor, in each case in such quantity as may be necessary to permit payment of such Additional Trust Expenses.

For the three months ended March 31, 2026 and 2025, the Trust incurred Sponsor’s Fees of $719,633 and $96,512, respectively. As of March 31, 2026 and December 31, 2025, there were no accrued and unpaid Sponsor’s Fees. In addition, the Sponsor may pay Additional Trust Expenses on behalf of the Trust, which are reimbursable by the Trust to the Sponsor. For the three months ended March 31, 2026 and 2025, the Sponsor did not pay any Additional Trust Expenses on behalf of the Trust.

On March 2, 2022, the Board of the Sponsor approved the purchase by DCG, the indirect parent company of the Sponsor, of up to $10 million worth of Shares of the Trust. Subsequently, DCG authorized such purchase. 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 2, 2022 through June 30, 2022, DCG purchased a total of $2.0 million worth of Shares of the Trust. From July 1, 2022 through March 31, 2026, DCG had not purchased any Shares of the Trust under this authorization.

Concentration Risk [Abstract]

Concentration Risk

7. Concentration Risk

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

Principal Market and Fair Value Determination

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 ZEC 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 ZEC 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 ZEC 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 ZEC 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 Trust considers investment transactions to be the receipt of ZEC for Share creations and the delivery of ZEC for Share redemptions or for payment of expenses in ZEC. At this time, the Trust is not accepting redemption requests from shareholders. The Trust records its investment transactions on a trade date basis and changes in fair value are reflected as net change in unrealized appreciation or depreciation on investments. Realized gains and losses are calculated using the specific identification method. Realized gains and losses are recognized in connection with transactions including settling obligations for the Sponsor’s Fee in ZEC.

Fair Value Measurement

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

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.
