What happened to the NAV per share of GSOL during the quarter?

Principal Market NAV per Share declined from $9.09 to $6.14 in Q1 2026, a total return of -32.45%. This movement closely tracked SOL’s price drop on the principal market from $123.97 to $82.60 over the same period, consistent with the Trust’s passive structure.

What fees does GSOL pay to its sponsor and how were they applied?

The Sponsor’s Fee is 0.35% of net assets annually , accrued daily and paid in SOL. In Q1 2026, Sponsor’s Fees were $57,206 and Sponsor’s Staking Fees were $247,082. These fees are funded by distributing small amounts of SOL, modestly reducing the Trust’s token holdings.

Grayscale Solana Staking ETF (GSOL) Q1 2026 NAV and SOL losses

Q: How did Grayscale Solana Staking ETF (GSOL) perform in Q1 2026?

GSOL’s net assets fell to $105.1 million in Q1 2026 , mainly due to a decline in the SOL price. Realized and unrealized losses on SOL totaled $56.6 million, partially offset by $1.9 million of net investment income from staking rewards and fee waivers.

Q: How many GSOL shares were outstanding and how did creations/redemptions impact the Trust?

GSOL had 17,114,135 shares outstanding at March 31, 2026 . During Q1 2026, 1,870,000 shares were issued and 2,390,000 were redeemed, for a net decrease of 520,000 shares. Redemptions required about 176,488 SOL to be distributed from the Trust’s holdings.

Rhea-AI Filing Summary

Grayscale Solana Staking ETF reports Q1 2026 results reflecting sharp moves in SOL. Net assets fell to $105.1 million at March 31, 2026 from $160.4 million, as the fair value of SOL declined from $123.97 to $82.60 per token.

The Trust recorded a net decrease in net assets from operations of $54.7 million, driven by $56.6 million of realized and unrealized losses on SOL, partly offset by $1.9 million of net investment income. Staking began in late 2025 and generated $2.2 million of staking reward income for the quarter.

Principal Market NAV per Share dropped from $9.09 to $6.14, a total return of -32.45%, while shares outstanding were 17,114,135 as of May 4, 2026. The Sponsor’s management fee, reduced to 0.35% annually, and a separate staking fee are paid in SOL, which slightly reduces SOL holdings over time.

Staking Reward Income financial

"Staking Reward Income | | $ | 2,198 | | | $ | - |"

Staking reward income is the earnings generated when a holder locks up digital tokens to help run or secure a blockchain network and, in return, receives additional tokens as a reward. It matters to investors because it can provide a steady, passive income stream and affect the effective return on an investment, while also exposing holders to risks like price swings, lock-up periods, and protocol problems—similar to earning interest on a savings account but with higher potential upsides and risks.

Principal Market NAV financial

"Principal Market NAV per Share | | $ | 6.14"

grantor trust regulatory

"the Sponsor takes the position that the Trust is properly treated as a grantor trust for U.S. federal income tax purposes"

A grantor trust is a legal arrangement where the person who puts assets into the trust keeps enough control or rights that, for tax and legal purposes, those assets are treated as still belonging to that person. For investors, that matters because income, gains and losses generated by the trust typically flow through to the grantor (or directly to investors) for tax reporting and distributions, affecting after-tax returns and cash flow predictability — think of it like a mailbox that forwards all the mail back to the sender rather than holding it inside.

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.

GRAYSCALE SOLANA STAKING ETF

NOTES TO THE UNAUDITED FINANCIAL STATEMENTS

1. Organization

Grayscale Solana Staking ETF (the “Trust”) is a Delaware Statutory Trust that was formed on November 9, 2021 and commenced operations on November 18, 2021. The Trust’s investment objective is for the value of the Shares (based on SOL per Share) to reflect the value of the SOL held by the Trust and to reflect rewards from Staking a portion of the Trust’s SOL, less the Trust’s expenses and other liabilities. The Trust issues Shares only in one or more blocks of 10,000 Shares (a block of 10,000 Shares is called a “Basket”) only to certain authorized participants (“Authorized Participants”) in exchange for SOL.

The Trust’s registration statement on Form S-1 relating to its continuous public offering of Shares was declared effective by the Securities and Exchange Commission (“SEC”) on October 28, 2025 and the Shares were listed and began trading on NYSE Arca, Inc. (“NYSE Arca”) under the symbol “GSOL” on October 29, 2025 (the “Uplisting Date”).

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

The Trust may receive staking rewards as a result of the Trust’s Staking pursuant to the Staking Arrangements.

Staking on the Solana Network refers to the use of SOL, or the permission for SOL to be used through an agent or otherwise, in the Solana Network’s proof-of-stake validation protocol in exchange for the receipt of staking rewards paid in-kind (“Staking”). The Trust Agreement permits the Trust to engage in Staking, and on October 6, 2025, the Trust commenced Staking pursuant to the Staking Arrangements. The Sponsor has caused, and from time to time may cause, the Trust to enter into written arrangements (the “Staking Arrangements”) with the Custodian and one or more third party staking providers (each, a “Staking Provider”), pursuant to which a portion of the Trust’s SOL is made available for staking through validator operations conducted by such Staking Providers (“Provider-Facilitated Staking”). The Custodian and the applicable Staking Provider are entitled to receive a portion of the gross staking rewards generated thereunder, representing the Custodian’s fee and the Staking Provider’s share of such staking rewards (collectively, the “Validator Fees”), with the remaining staking rewards received by the Trust, as discussed in Note 6.

Liquidity Providers facilitate the purchase and sale of SOL 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 SOL transactions are third parties that are not affiliated with the Sponsor or the Trust and are not acting as agents of the Trust, the Sponsor, or any Authorized Participant. Except for the contractual relationships between each Liquidity Provider and GSIS in its capacity as the Liquidity Engager, there is no contractual relationship between each Liquidity Provider and the Trust, the Sponsor, or any Authorized Participant. The Liquidity Engager may engage additional Liquidity Providers who are unaffiliated with the Trust in the future.

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

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

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

The marketing agent for the Trust (the “Marketing Agent”) is Foreside Fund Services, LLC. The Marketing Agent provides the following services to the Sponsor: (i) assist the Sponsor in facilitating Participant Agreements between and among Authorized Participants, the Sponsor, on behalf of the Trust, and the Transfer Agent; (ii) provide prospectuses to Authorized Participants; (iii) work with the Transfer Agent to review and approve orders placed by the Authorized Participants and transmitted to the Transfer Agent; (iv) review and file applicable marketing materials with FINRA and (v) maintain, reproduce and store applicable books and records.

On April 17, 2023, the Trust received notice that its Shares were qualified for public trading on the OTCQB U.S. Market (“OTCQB”) of OTC Markets Group Inc. On March 7, 2024, the Trust qualified to trade on the OTCQX Best Market®(“OTCQX”) of OTC Markets Group Inc. Until October 28, 2025, the Trust’s trading symbol on OTCQX was “GSOL.” On October 29, 2025, Shares of the Trust began trading on NYSE Arca following the effectiveness of the Trust’s registration statement on Form S-1, as amended (File No. 333-286374). The Trust’s trading symbol on NYSE Arca is “GSOL” and the CUSIP number for its Shares is 38965D104.

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

The Sponsor has committed to cause the Trust to abandon irrevocably for no direct or indirect consideration, effective immediately prior to each time at which the Trust creates or redeems Shares, all Incidental Rights and IR Virtual Currency to which it would otherwise be entitled as of such time. In furtherance of that commitment, the Prime Broker Agreement provides that the Trust is abandoning irrevocably for no direct or indirect consideration, effective immediately prior to each Creation Time and each Redemption Time, all Incidental Rights or IR Virtual Currency to which it would otherwise be entitled as of such time. The Sponsor has committed to cause the Trust not to take any Affirmative Action to acquire any Incidental Rights or IR Virtual Currency, thereby irrevocably abandoning any Incidental Rights and IR Virtual Currency to which the Trust may become entitled in the future. Because the Sponsor has now committed to causing the Trust to irrevocably abandon all Incidental Rights and IR Virtual Currency to which the Trust otherwise would become entitled in the future, and causing the Trust not to take any Affirmative Actions, the Trust will not receive any direct or indirect consideration for the Incidental Rights or IR Virtual Currency and thus the value of the Shares will not reflect the value of the Incidental Rights or IR Virtual Currency. In addition, in the event the Sponsor seeks to change the Trust’s policy with respect to Incidental Rights or IR Virtual Currency, an application would need to be filed with the SEC by NYSE Arca seeking approval to amend its listing rules to permit the Trust to distribute the Incidental Rights or IR Virtual Currency in-kind to an agent of the shareholders for resale by such agent.

2. Summary of Significant Accounting Policies

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

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

The financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). The Trust qualifies as an investment company for accounting purposes pursuant to the accounting and reporting guidance under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, Financial Services—Investment Companies. As such, the Trust is exempt from the requirement to present a statement of cash flows pursuant to ASC Topic 230, Statement of Cash Flows. Accordingly, a statement of cash flows has not been presented. The Trust uses fair value as its method of accounting for SOL 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 SOL, including receiving SOL for the creation of Shares and delivering SOL for the redemption of Shares and for the payment of the Sponsor’s Fee and Sponsor’s Staking 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 SOL 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 SOL 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 SOL 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 SOL 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.

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 SOL for Share creations and the delivery of SOL for Share redemptions, or for payment of expenses in SOL. 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 SOL.

Solana Staking

The Trust earns staking rewards by delegating a portion of its SOL on the Solana Network’s proof-of-stake consensus protocol. The Sponsor has entered into contractual arrangements with the Custodian and one or more third-party staking service providers, which may include affiliates of the Custodian or other institutional validators, to facilitate the staking of the Trust’s SOL. The Trust retains control of its SOL throughout the staking process. The delegation of SOL for staking purposes does not constitute a sale, transfer, or other derecognition event, as control of the SOL is not transferred to the validator or staking provider. Accordingly, the staked SOL is not derecognized under ASC Topic 610-20, Other Income, Gains and Losses from the Derecognition of Nonfinancial Assets, or ASC Topic 350-60, Intangibles, Goodwill and Other, Crypto Assets.

The Trust recognizes staking rewards as revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). Under the staking arrangements, the validator (e.g., the Custodian or other staking provider) is considered the customer, as it receives access to the Trust’s staking capacity (i.e., the delegation of SOL), which represents the Trust’s performance obligation. In exchange, the Trust is entitled to staking rewards generated by the Solana protocol, net of Validator Fees.

Staking rewards represent variable consideration, as the amount of rewards is not known until the applicable validation activities are completed, and the Trust receives rewards in their custodial account. The contract term is the length of each staking epoch. Staking rewards are recognized as revenue when the Trust satisfies its performance obligations (i.e., successfully validates blocks or transactions as determined by the protocol). Staking rewards are received in SOL, which represents non-cash consideration. Non-cash consideration is measured at fair value at the inception of each contract (i.e., the beginning of each staking epoch), in accordance with ASC 606.

Because the Trust is not the principal to the block validation service, it does not control the full output of the reward-generating activity, and instead receives net staking rewards, after Validator Fees are deducted. As such, the Trust presents staking revenue on a net basis, reflecting only the portion of protocol rewards to which it is entitled. Staking revenue is recorded as staking reward income on the Statements of Operations. Any staking (block) rewards that have been earned and collected by validators (held in the validator’s address and under the validator’s control) but not yet transferred to the Trust’s digital asset wallet are recorded as a Staking Reward receivable, at fair value on the Statement of Assets and Liabilities.

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 expenses, the Sponsor’s Fee, related party, and Sponsor’s Staking Fee, related party, are included in the accompanying Statements of Operations.

3. Fair Value of SOL

SOL 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 1,272,221.25983000 and 1,293,746.87210555 SOL, respectively.

The Trust determined the fair value per SOL to be $82.60 and $123.97 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 SOL and the respective fair value:

4. Creations and Redemptions of Shares

The Trust creates and redeems Shares from time to time, but only in one or more Baskets issued to the Authorized Participant in exchange for the delivery of SOL to the Trust or the distribution of SOL by the Trust. The amount of SOL required for each Creation Basket or Redemption Basket is determined by dividing (x) the amount of SOL 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 SOL 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 0.0743 and 0.0734 of one SOL at March 31, 2026 and December 31, 2025, respectively.

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

5. Income Taxes

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

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

In accordance with U.S. GAAP, the Trust has defined the threshold for recognizing the benefits of tax positions in the financial statements as “more-likely-than-not” to be sustained by the applicable taxing authority and requires measurement of a tax position meeting the “more-likely-than-not” threshold, based on the largest benefit that is more than 50% likely to be realized. Tax positions deemed to meet the “more-likely-than-not” threshold are recorded as a tax benefit in the current period. As of, and during the periods ended March 31, 2026 and December 31, 2025, the Trust did not have a liability for any unrecognized tax amounts. However, the Sponsor’s conclusions concerning its determination of “more-likely-than-not” tax positions may be subject to review and adjustment at a later date based on factors including, but not limited to, further implementation guidance, and ongoing analyses of and changes to tax laws, regulations and interpretations thereof.

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

6. Related Parties

The Trust considered the following entities, their directors, and certain employees to be related parties of the Trust as of March 31, 2026: DCG, GSO, GSIS, and Grayscale Securities, LLC. As of March 31, 2026 and December 31, 2025, 33,297 and 164,214 Shares of the Trust were held by related parties of the Trust, respectively.

On October 27, 2025, the Sponsor and the Trustee entered into Amendment No. 1 to the Second Amended and Restated Trust Agreement in order to reduce the Sponsor’s Fee to 0.35%, effective as of the Uplisting Date. As a result, effective October 29, 2025, the Sponsor’s Fee was lowered from 2.5% to 0.35%. In accordance with the Trust Agreement governing the Trust, the Trust pays a fee to the Sponsor, calculated as 0.35% 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 SOL daily in arrears. The amount of SOL payable in respect of each daily U.S. dollar accrual will be determined by reference to the same U.S. dollar value of SOL used to determine such accrual. For purposes of these financial statements, the U.S. dollar value of SOL 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.

Pursuant to the Staking Arrangements, the Custodian and the applicable Staking Provider are entitled to receive a portion of the gross staking rewards generated thereunder, representing the Custodian’s fee and the Staking Provider’s share of such staking rewards (collectively, the “Validator Fees”), with the remaining staking rewards received by the Trust. In addition, the Sponsor is entitled to receive a fee equal to a portion of the staking rewards, payable in SOL, which accrues daily in U.S. dollars and is calculated as a per annum percentage of the staking rewards received by the Trust, as directed by the Sponsor in its sole discretion (the “Sponsor’s Staking Fee”). The Sponsor’s Staking Fee is payable daily in arrears. From November 5, 2025 until February 5, 2026 (the “Fee Waiver Period”), the Sponsor waived a portion of the fees associated with Staking, such that the Sponsor’s Staking Fee, the Custodian’s fee and the Staking Provider’s share of the gross staking rewards comprised an aggregate of 5% of the gross staking rewards generated under the Staking Arrangements, with the Trust receiving and retaining the remainder of such gross Staking Consideration. Following the expiration of the Fee Waiver Period on February 5, 2026, the Sponsor’s Staking Fee, the Custodian’s fee and the Staking Provider’s share of the gross staking rewards comprise an aggregate of 23% of the gross staking rewards generated under the Staking Arrangements. A portion of the gross staking rewards is paid to non-related parties and the Trust receives and retains the remainder of such gross staking rewards.

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 SOL 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 SOL 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 SOL in kind to the Sponsor, in each case in such quantity as may be necessary to permit payment of such Additional Trust Expenses.

The Sponsor, from time to time, may temporarily waive all or a portion of the Sponsor’s Fee of the Trust in its discretion for stated periods of time. Effective November 5, 2025, the Sponsor determined to waive a portion of the Sponsor’s Fee until the earlier of (x) February 5, 2026 and (y) the first date on which the NAV of the Trust exceeds $1.0 billion (such period, the “Fee Waiver Period”). Following the expiration date of the three-month waiver period on February 5, 2026 (the “Sponsor’s Fee Waiver Expiration Date”), the Sponsor’s Fee is 0.35%.

For the period from the Sponsor’s Fee Waiver Expiration Date through March 31, 2026 and the three months ended March 31, 2025, the Trust incurred Sponsor’s Fees of $57,206 and $589,024, 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.

For the three months ended March 31, 2026, the Trust incurred Sponsor’s Staking Fees of $247,082.

7. Concentration Risk

The Trust’s investment portfolio is concentrated in SOL, and its net asset value and results of operations are directly affected by the price of SOL, 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 SOL and its supporting infrastructure, including market liquidity constraints and operational or cybersecurity risks associated with the custody and transfer of SOL.

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

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

9. Indemnifications

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

10. Subsequent Events

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

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

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

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

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

Trust Overview

The Trust is a passive entity that is managed and administered by the Sponsor and does not have any officers, directors or employees. The Trust holds SOL and, from time to time on a periodic basis, issues Creation Baskets in exchange for deposits of SOL. On October 28, 2025, in connection with the approval of application under the Generic Listing Standards and the effectiveness of the registration statement on Form S-1, the Sponsor authorized the commencement of a redemption program. Shares of the Trust began trading on NYSE Arca on October 29, 2025, following the effectiveness of the Trust’s registration statement on Form S-1. 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 SOL. 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 SOL per Share) to reflect the value of the SOL held by the Trust, including SOL earned as Staking Consideration, 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 SOL, the Shares are designed to provide investors with a cost-effective and convenient way to gain investment exposure to SOL. 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.

Staking

On October 6, 2025, the Trust began staking its SOL pursuant to staking arrangements with the Custodian and certain third-party staking providers and earns staking rewards in the form of additional SOL (“Staking Consideration”). The amount of Staking Consideration received by the Trust is influenced by factors including Solana Network conditions, protocol-level reward rates, the amount of SOL held by the Trust and the portion of the Trust’s SOL that is staked, and the Trust does not expect Staking Consideration to be earned at a consistent rate. Staking also introduces operational and liquidity considerations, including that staked SOL may be inaccessible for a period of time required to un-stake and withdraw SOL under Solana Network protocols and the Trust’s dependence on third-party staking providers for the execution of staking activities.

Pursuant to the Trust’s staking arrangements and the Trust Agreement, a portion of gross Staking Consideration is allocated among the Custodian, the applicable staking providers and the Sponsor (the “Sponsor’s Staking Fee”), with the remainder retained by the Trust. Staking Consideration retained by the Trust increases the Trust’s SOL holdings, while distributions or sales of SOL reduce the Trust’s SOL holdings. The Trust may distribute Staking Consideration (in SOL or cash from the sale of SOL) to shareholders at the Sponsor’s discretion and subject to the Trust Agreement.

Critical Accounting Policies and Estimates

Investment Transactions and Revenue Recognition

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

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 SOL 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 SOL is sold in its principal market to market participants or, in the absence of a principal market, the most advantageous market. Market participants are defined as buyers and sellers in the principal or most advantageous market that are

independent, knowledgeable, and willing and able to transact.

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

•

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

•

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.

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 SOL 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, SOL and price of SOL amounts, are in thousands)


	Three Months Ended March 31,
	2026			2025
Net realized and unrealized loss on investment in SOL	$	(56,577	)	$	(36,648	)
Net decrease in net assets resulting from operations	$	(54,684	)	$	(37,237	)
Net assets(1)	$	105,118		$	66,515

(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 SOL 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 SOL for the three months ended March 31, 2026 was ($56,577), which includes a realized loss of ($32) on the transfer of SOL to pay the Sponsor’s Fee, a realized loss of ($5,909) on the sale of SOL to meet redemptions, a realized loss of ($102) on the sale of SOL to pay the Sponsor’s Staking Fee, net change in unrealized appreciation/depreciation on investment the Sponsor’s Staking Fee payable in SOL of ($25), net change in unrealized appreciation/depreciation on Staking Reward Receivable in SOL of ($1) and net change in unrealized appreciation/depreciation on investment in SOL of ($50,510). Net realized and unrealized gain on investment in SOL for the period was driven by SOL price depreciation from $123.97 per SOL as of December 31, 2025, to $82.60 per SOL as of March 31, 2026. Net decrease in net assets resulting from operations was ($54,684) for the three months ended March 31, 2026, which consisted of the net realized and unrealized gain on investment in SOL, less the net investment income of $1,893. Net assets decreased to $105,118 at March 31, 2026, a 34% decrease for the three-month period. The decrease in net assets resulted from the aforementioned SOL price depreciation, the withdrawal of approximately 667 SOL to pay the foregoing Sponsor’s Fee, the withdrawal of approximately 3,261 SOL to pay the foregoing Sponsor’s Staking Fee, the payable of approximately 89 SOL to pay the foregoing Sponsor’s Staking Fee, and the redemption of approximately 176,488 SOL with a value of $17,933 from the Trust, partially offset by the contribution of approximately 137,592 SOL with a value of $17,378 to the Trust in connection with Share creations during the period and the contribution of approximately 21,437 SOL with a value of $2,198 in connection with Staking Rewards.

Net realized and unrealized loss on investment in SOL for the three months ended March 31, 2025 was ($36,648), which includes a realized gain of $167 on the transfer of SOL to pay the Sponsor’s Fee and net change in unrealized appreciation/depreciation on investment in SOL of ($36,815). Net realized and unrealized loss on investment in SOL for the period was driven by SOL price depreciation from $193.69 per SOL as of December 31, 2024, to $125.23 per SOL as of March 31, 2025. Net decrease in net assets resulting from operations was ($37,237) for the three months ended March 31, 2025, which consisted of the net realized and unrealized loss on investment in SOL, plus the Sponsor’s Fee of $589. Net assets decreased to $66,515 at March 31, 2025, a 35% decrease for the three-month period. The decrease in net assets resulted from the aforementioned SOL price depreciation and the withdrawal of approximately 3,279 SOL to pay the foregoing Sponsor’s Fee, partially offset by the contribution of approximately 4,546 SOL with a value of $1,121 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 SOL in the Digital Asset Market to pay Additional Trust Expenses on behalf of the Trust, the Sponsor endeavors to sell the exact amount of SOL needed to pay expenses in order to minimize the Trust’s holdings of assets other than SOL. 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 expenses of the Trust during the periods covered by this Quarterly Report were the Sponsor’s Fee and the Sponsor’s Staking 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 SOL on principal market	$	82.60	$	125.23
Principal Market NAV per Share(1)	$	6.14	$	9.21
Principal Market NAV(1)	$	105,117,970	$	66,514,737
Index Price	$	82.63	$	125.22
NAV per Share(2)	$	6.14	$	9.21
NAV(2)	$	105,156,148	$	66,509,426

(1)

The Principal Market NAV and Principal Market NAV per Share are calculated using the fair value of SOL 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 Binance, Bitstamp by Robinhood, Bullish, Bybit, Crypto.com, Gate, HashKey, Kraken, LMAX Digital, and OKX. The Digital Asset Trading Platforms included in the Index as of March 31, 2025 were Coinbase, LMAX Digital, Kraken, Crypto.com and Bitstamp by Robinhood. See “Item 1. Business—Overview of the Solana Industry and Market—SOL Value—The Index and the Index Price” in our Annual Report for a description of the Index and the Index Price.

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

Historical NAV and SOL Prices

As movements in the price of SOL will directly affect the price of the Shares, investors should understand recent movements in the price of SOL. Investors, however, should also be aware that past movements in the SOL 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 October 29, 2025 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 October 29, 2025, 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 October 29, 2025, 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 October 29, 2025 is not directly comparable to, and should not be used to make conclusions in conjunction with, the Trust’s performance for periods subsequent to October 29, 2025.

The following chart illustrates the movement in the Trust’s NAV per Share (as adjusted for the Reverse Share Splits and Share Split for periods prior to June 23, 2022, March 20, 2023, and December 9, 2024, respectively) versus the Index Price and the Trust’s Principal Market NAV per Share (as adjusted for the Reverse Share Splits and Share Split for periods prior to June 23, 2022, March 20, 2023, and December 9, 2024, respectively) from November 18, 2021 (the commencement of the Trust’s operations) to March 31, 2026. For more information on the determination of the Trust’s NAV, see “Item 1. Business—Overview of the Solana Industry and Market—SOL Value—The Index and the Index Price” in our Annual Report.

The following table illustrates the movements in the Index Price from November 18, 2021 (the commencement of the Trust’s operations) to March 31, 2026.
