Item 9A. Controls and Procedures. Disclosure Controls and Procedures The duly authorized officers of the Sponsor performing functions equivalent to those a principal executive officer and principal financial officer of the Trust would perform if the Trust had any officers, with the participation of the Trustee, have evaluated the effectiveness of the Trust’s disclosure controls and procedures, and have concluded that the disclosure controls and procedures of the Trust were effective as of December 31, 2025, the end of the period covered by this report, to provide reasonable assurance that information required to be disclosed in the reports that the Trust files or submits under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported, within the time periods specified in the applicable rules and forms, and that it is accumulated and communicated to the duly authorized officers of the Sponsor performing functions equivalent to those a principal executive officer and principal financial officer of the Trust would perform if the Trust had any officers, as appropriate to allow timely decisions regarding required disclosure. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Management ’ s Report on Internal Control over Financial Reporting The Sponsor’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Exchange Act Rules 13a-15(f) and 15d-15(f). The Trust’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States of America. Internal control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the Trust’s assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles and that the Trust’s receipts and expenditures are being made only in accordance with appropriate authorizations and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Trust’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become ineffective because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. The Sponsor’s management, including the principal executive officer and principal financial officer of the Sponsor, assessed the effectiveness of the Trust’s internal control over financial reporting as of December 31, 2025. In making its assessment, the Sponsor’s management has utilized the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in its report entitled “Internal Control – Integrated Framework” (2013). Based on their assessment and those criteria, the Sponsor’s management concluded that the Trust maintained effective internal control over financial reporting as of December 31, 2025. The effectiveness of the Trust’s internal control over financial reporting as of December 31, 2025 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included herein. Changes in Internal Control over Financial Reporting There were no changes in the Trust’s internal control over financial reporting that occurred during the quarter ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, the Trust’s internal control over financial reporting.

We also have audited the Trust’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Trust as of December 31, 2025 and 2024, and the results of its operations, changes in its net assets, and its cash flows for the year ended December 31, 2025 and for the period May 21, 2024 (date of seeding) to December 31, 2024 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Trust maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO. Basis for Opinions The Sponsor’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Trust’s financial statements and on the Trust’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Trust in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. PricewaterhouseCoopers LLP, 2001 Market Street, Suite 1800, Philadelphia, PA 19103 T: (267) 330 3000, www.pwc.com/us F-2 Table of Contents Definition and Limitations of Internal Control over Financial Reporting A trust’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A trust’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the trust; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the trust are being made only in accordance with authorizations of the Sponsor’s management and the Sponsor of the trust; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the trust’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Critical Audit Matters The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Existence of and Rights to the Investment in Ether As described in Notes 1 and 2 to the financial statements, the Trust accounts for its investment in ether at fair value in accordance with its classification as an investment company for accounting purposes. As of December 31, 2025, the fair value of the Trust’s investment in ether was $10.3 billion, with a respective cost basis of $12.5 billion. As disclosed by management, digital assets, including ether, are controllable only by the possessor of both the unique public key and private key or keys relating to the Ethereum network address, or “wallet”, at which the digital asset is held. Private keys must be safeguarded and kept private in order to prevent a third party from accessing the digital asset held in such wallet. The loss, theft, compromise or destruction of a private key required to access a digital asset may be irreversible. If a private key is lost, stolen, destroyed or otherwise compromised and no backup of the private key is accessible, the owner would be unable to access the digital asset corresponding to that private key and the private key will not be capable of being restored by the digital asset network resulting in the total loss of the value of the digital asset linked to the private key. The principal considerations for our determination that performing procedures relating to the existence of, and the Trust’s rights to, the investment in ether is a critical audit matter are (i) a high degree of auditor effort in performing procedures and evaluating audit evidence related to the existence of, and the Trust’s rights to, the investment in ether and (ii) the audit effort involved the use of professionals with specialized skill and knowledge. F-3 Table of Contents Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the financial statements. These procedures included the involvement of professionals with specialized skill and knowledge to assist in evaluating evidence of the effectiveness of the third-party custodian’s controls related to (i) reconciliation of the investment in ether from the third-party custodian’s records to the public blockchain and (ii) safeguarding of the investment in ether held by the third-party custodian, including the generation of the private cryptographic keys and the storing of these keys. These procedures also included, among others (i) confirming the Trust’s investment in ether with the third-party custodian as of December 31, 2025 and comparing the information in the confirmation response to the Trust’s records; (ii) testing purchases and sales executed by the Trust related to the investment in ether for a sample of transactions by obtaining and inspecting source documents, such as trade tickets, third-party custodian statements, and bank statements, as well as whether the transactions were appropriately authorized by the Trust by obtaining and inspecting approval records; and (iii) the involvement of professionals with specialized skill and knowledge to assist in (a) comparing the investment in ether from the third-party custodian’s confirmation response to the public blockchain and (b) evaluating whether the Trust had access to the private cryptographic keys held by the third-party custodian by tracing certain withdrawal transactions executed by the Trust to the public blockchain. /s/ PricewaterhouseCoopers LLP Philadelphia, Pennsylvania February 27, 2026 We have served as the Trust’s auditor since 2024.

F- 9 Table of Contents iShares ® Ethereum Trust ETF Notes to Financial Statements December 31, 2025 1 - Organization The iShares Ethereum Trust ETF (the “Trust”) was organized on November 9, 2023 as a Delaware statutory trust. The trustee is BlackRock Fund Advisors (the “Trustee”), which is responsible for the day-to-day administration of the Trust. The Trust’s sponsor is iShares Delaware Trust Sponsor LLC, a Delaware limited liability company (the “Sponsor”). The Bank of New York Mellon serves as the “Trust Administrator.” The Trust is governed by the provisions of the Third Amended and Restated Trust Agreement (the “Trust Agreement”) executed by the Sponsor, the Trustee and Wilmington Trust, National Association, a national association (“Delaware Trustee”), as of July 8, 2025. The Trust issues units of beneficial interest (“Shares”) representing fractional undivided beneficial interests in its net assets. On May 21, 2024, BlackRock Financial Management, Inc. (the “Seed Capital Investor”) purchased 400,000 Shares for $ 10,000,000 at a per-Share price of $ 25.00 (the “Seed Creation Baskets”). The Seed Capital Investor did not receive from the Trust, the Sponsor or any of their affiliates any fee or other compensation in connection with the purchase of Seed Creation Baskets. On June 24, 2024, the Trust purchased approximately 3,031 ether with the proceeds of the Seed Creation Baskets using Coinbase Inc. (the “Prime Execution Agent”). The costs incurred in connection with the purchase of ether with the proceeds of the Seed Creation Baskets were borne by the Trust. The Sponsor’s Fee started accruing daily at an annualized rate equal to 0.25 % of the net asset value of the Trust on June 24, 2024. 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 July 22, 2024 ( Effective Date) and the Shares were listed on The Nasdaq Stock Market LLC (“NASDAQ”) on July 23, 2024. On July 29, 2025, the SEC issued 19b - 4 orders permitting in-kind creations and redemptions by authorized participants for the Trust. On July 31, 2025, the post-effective amendment to the Trust’s registration statement on Form S- 1 was declared effective. As a result of these regulatory actions, the Trust is authorized to create and redeem shares with authorized participants on an in-kind basis. The Trust seeks to reflect generally the performance of the price of ether. The Trust seeks to reflect such performance before payment of the Trust’s expenses and liabilities. The Shares are intended to constitute a simple means of making an investment similar to an investment in ether. The Trust qualifies as an investment company solely for accounting purposes and not for any other purpose and follows the accounting and reporting guidance under the Financial Accounting Standards Board Accounting Standards Codification Topic 946, Financial Services - Investment Companies, but is not registered, and is not required to be registered, as an investment company under the Investment Company Act of 1940, as amended. 2 - Significant Accounting Policies A. Basis of Accounting The following significant accounting policies are consistently followed by the Trust in the preparation of its financial statements in conformity with generally accepted accounting principles in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. B. Ether Coinbase Custody Trust Company, LLC (the “Ether Custodian”) is responsible for safekeeping the ether owned by the Trust. Anchorage Digital Bank N.A. is the “Additional Ether Custodian” for the Trust. At the current time, the Sponsor has no plans to move any of the Trust’s ether to the Additional Ether Custodian. The Ether Custodian and the Additional Ether Custodian are appointed by the Trustee. The net asset value of the Trust equals the total assets of the Trust, which consists solely of ether and cash, less total liabilities of the Trust, each determined by the Trustee pursuant to policies established from time to time by the Trustee or its affiliates or otherwise described herein. The Trust’s periodic financial statements are prepared in accordance with the Financial Accounting Standards Board Accounting Standards Codification Topic 820, “Fair Value Measurement” (“ASC Topic 820” ) and utilize an exchange-traded price from the Trust’s principal market for ether as of 11:59 p.m. Eastern Time (“ET”) on the Trust’s financial statement measurement date. The Sponsor determines in its sole discretion the valuation sources and policies used to prepare the Trust’s financial statements in accordance with U.S. GAAP. The Trust engages a third -party vendor to obtain a price from a principal market for ether, which is determined and designated by such third -party vendor daily based on its consideration of several exchange characteristics, including oversight, and the volume and frequency of trades. The Sponsor has the exclusive authority to determine the Trust’s net asset value, which it has delegated to the Trustee under the Trust Agreement. The Trustee has delegated to the Trust Administrator the responsibility to calculate the net asset value of the Trust and the net asset value per Share (“NAV”), based on a pricing source selected by the Trustee. In determining the Trust’s net asset value, the Trust Administrator values the ether held by the Trust based on an index (the “Index”), unless the Sponsor in its sole discretion determines that the Index is unreliable. The methodology used to calculate the Index price to value ether in determining the net asset value of the Trust may not be deemed consistent with U.S. GAAP. The CME CF Ether–Dollar Reference Rate – New York Variant for the ether – U.S. Dollar trading pair (the “CF Benchmarks Index”) shall constitute the Index, unless the CF Benchmarks Index is not available or the Sponsor in its sole discretion determines the CF Benchmarks Index is unreliable as the Index and therefore determines not to use the CF Benchmarks Index as the Index. If the CF Benchmarks Index is not available or the Sponsor determines, in its sole discretion, that the CF Benchmarks Index is unreliable (together a “Fair Value Event”), the Trust’s holdings may be fair valued on a temporary basis in accordance with the fair value policies approved by the Trustee. F- 10 Table of Contents Additionally, the Trust Administrator monitors for unusual prices and escalates to the Trustee if detected. If the CF Benchmarks Index is not used, the Trust will notify Shareholders in a prospectus supplement, in its periodic Exchange Act reports and/or on the Trust’s website. The Trust Administrator calculates the net asset value of the Trust and the NAV once on each day other than a Saturday or a Sunday or a day on which NASDAQ is closed for regular trading (a “Business Day”). The NAV for a normal trading day will be released after 4:00 p.m. ET. Trading during the core trading session on NASDAQ typically closes at 4:00 p.m. ET. However, NAVs are not officially released until after the completion of a comprehensive review of the NAV and prices utilized to determine the NAV of the Trust by the Trust Administrator. Upon the completion of the end of day reviews by the Trust Administrator the NAV is released to the public typically by 5:30 p.m. ET and generally no later than 8:00 p.m. ET. The period between 4:00 p.m. ET and the NAV release after 5:30 p.m. ET (or later) provides an opportunity for the Trust Administrator and the Trustee to detect, flag, investigate, and correct unusual pricing should it occur and implement a Fair Value Event, if necessary. Any such correction could adversely affect the value of the Shares. The Trust’s periodic financial statements may not utilize the net asset value of the Trust to the extent the methodology used to calculate the Index is deemed not to be consistent with U.S. GAAP. Gain or loss on sales of ether is calculated on a trade date basis using the average cost method. The following tables summarize activity in ether for the year ended December 31, 2025 and the period from May 21, 2024 ( Date of Seeding) to December 31, 2024: Year Ended December 31, 2025 Quantity Cost Fair Value Realized Gain (Loss) Beginning balance 1,071,415 $ 3,543,902,275 $ 3,571,669,777 $ — Ether purchased (a) 4,132,755 14,798,250,413 14,798,250,413 — Ether sold for the redemption of shares (b) ( 1,732,296 ) ( 5,788,168,476 ) ( 5,753,722,872 ) ( 34,445,604 ) Ether sold to pay expenses ( 4,645 ) ( 15,936,452 ) ( 16,071,905 ) 135,453 Net realized loss — — ( 34,310,151 ) — Net change in unrealized appreciation/depreciation — — ( 2,262,771,767 ) — Ending balance 3,467,229 $ 12,538,047,760 $ 10,303,043,495 $ ( 34,310,151 ) (a) Includes Ether purchased in-kind for Shares issued of $ 602,266,086 .

Calculation of Net Asset Value On each Business Day, as soon as practicable after 4:00 p.m.ET, the net asset value of the Trust is obtained by subtracting all accrued fees, expenses and other liabilities of the Trust from the total assets held by the Trust. The Trust Administrator computes the NAV by dividing the net asset value of the Trust by the number of Shares outstanding on the date the computation is made. D. Cash and Cash Equivalents Cash includes non-interest bearing, non-restricted cash maintained with one banking institution that does not exceed U.S. federally insured limits. E. Offering of the Shares Shares are issued and redeemed continuously in aggregations of 40,000 Shares (a “Basket”) or integral multiples thereof, based on the quantity of ether attributable to each Share (net of accrued but unpaid Sponsor’s Fee and any accrued but unpaid expenses or liabilities). Individual investors cannot purchase or redeem Shares in direct transactions with the Trust. Only registered broker-dealers that are eligible to settle securities transactions through the book-entry facilities of the Depository Trust Company and that have entered into a contractual arrangement with the Sponsor governing, among other matters, the creation and redemption of Shares (such broker-dealers, the “Authorized Participants”), can place orders to receive Baskets in exchange for cash or ether. Baskets may be redeemed by the Trust in exchange for an amount of ether corresponding to their redemption value or for the cash proceeds from selling the amount of ether corresponding to their redemption value. F- 11 Table of Contents In connection with cash creations and redemptions, the Trust engages in ether transactions for converting cash into ether (in association with purchase orders) and ether into cash (in association with redemption orders) by choosing, in its sole discretion, to trade directly with third parties (each, an “Ether Trading Counterparty”), who are not registered broker-dealers pursuant to written agreements between such Ether Trading Counterparties and the Trust, or choosing to trade through the Prime Execution Agent acting in an agency capacity with third parties through its Coinbase Prime service pursuant to the Prime Execution Agent Agreement. Share activities for the year ended December 31, 2025 and the period from May 21, 2024 ( Date of Seeding) to December 31, 2024 were as follows: December 31, 2025 2024 (a) Shares Amount Shares Amount Shares issued 546,320,000 $ 14,798,904,285 147,680,000 $ 3,695,353,729 Shares redeemed ( 229,080,000 ) ( 5,753,916,924 ) ( 6,200,000 ) ( 158,510,365 ) Net increase 317,240,000 $ 9,044,987,361 141,480,000 $ 3,536,843,364 (a) Period from May 21, 2024 ( Date of Seeding) to December 31, 2024. F. Federal Income Taxes The Trust is treated as a grantor trust for federal income tax purposes and, therefore, no provision for federal income taxes is required. Any interest, expenses, gains and losses are passed through to the holders of Shares of the Trust. The Sponsor has analyzed applicable tax laws and regulations and their application to the Trust as of December 31, 2025 and does not believe that there are any uncertain tax positions that require recognition of a tax liability. G. Segment Reporting The Chief Financial Officer of the Sponsor acts as the Trust’s Chief Operating Decision Maker (“CODM”) and is responsible for assessing performance and allocating resources with respect to the Trust. The CODM has concluded that the Trust operates as a single operating segment since the Trust has a single investment strategy as disclosed in its prospectus, against which the CODM assesses performance. The financial information provided to and reviewed by the CODM is presented within the Trust’s financial statements. 3 - Trust Expenses The Sponsor’s Fee is accrued daily at an annualized rate equal to 0.25 % of the net asset value of the Trust and is payable at least quarterly in arrears in U.S. dollars or in-kind or any combination thereof. For the year ended December 31, 2025, the Sponsor’s Fee was $ 20,159,102 . The Sponsor may, at its sole discretion and from time to time, waive all or a portion of the Sponsor’s Fee for stated periods of time. The Sponsor is under no obligation to waive any portion of its fees and any such waiver shall create no obligation to waive any such fees during any period not covered by the waiver. For a twelve -month period, starting July 23, 2024, the Sponsor waived a portion of the Sponsor’s Fee so that the Sponsor’s Fee after the fee waiver would be equal to 0.12 % of the net asset value of the Trust for the first $ 2.5 billion of the Trust’s assets. In the future, if the Sponsor decides to waive all or a portion of the Sponsor’s Fee, Shareholders will be notified in a prospectus supplement, in its periodic Exchange Act reports and/or on the Trust’s website. For the year ended December 31, 2025, the amount waived was $ 1,748,012 . The Sponsor has agreed to assume the marketing and the following administrative expenses of the Trust: the fees of the Trustee, the Delaware Trustee, the Trust Administrator, the Ether Custodian, the Additional Ether Custodian, and The Bank of New York Mellon (the “Cash Custodian”), NASDAQ listing fees, SEC registration fees, printing and mailing costs, tax reporting fees, audit fees, license fees and expenses and up to $ 500,000 per annum in ordinary legal fees and expenses. The Sponsor may determine in its sole discretion to assume legal fees and expenses of the Trust in excess of the $ 500,000 per annum required under the Trust Agreement. To the extent that the Sponsor does not voluntarily assume such fees and expenses, they will be the responsibility of the Trust. 4 - Related Parties The Sponsor and the Trustee are considered to be related parties to the Trust. The Trustee’s fee is paid by the Sponsor and is not a separate expense of the Trust. F- 12 Table of Contents 5 - Indemnification The Trust Agreement provides that the Sponsor shall indemnify the Trustee, its directors, employees, delegees and agents against, and hold each of them harmless from, any loss, liability, claim, cost, expense or judgment of any kind whatsoever (including the reasonable fees and expenses of counsel) that is incurred by any of them and that arises out of or is related to ( 1 ) any offer or sale by the Trust of Baskets, ( 2 ) acts performed or omitted pursuant to the provisions of the Trust Agreement (A) by the Trustee, its directors, employees, delegees and agents or (B) by the Sponsor or ( 3 ) any filings with or submissions to the SEC in connection with or with respect to the Shares, except that the Sponsor shall not have any obligations to pay any indemnification amounts incurred as a result of and attributable to ( x ) the willful misconduct, gross negligence or bad faith of, or material breach of the terms of the Trust Agreement by, the Trustee, (y) information furnished in writing by the Trustee to the Sponsor expressly for use in the registration statement, or any amendment thereto, filed with the SEC relating to the Shares that is not materially altered by the Sponsor or (z) any misrepresentations or omissions made by an authorized participant (other than the Sponsor) in connection with such authorized participant’s offer and sale of Shares. The Trust Agreement provides that the Trustee shall indemnify the Sponsor, its directors, employees, delegees and agents against, and hold each of them harmless from, any loss, liability, claim, cost, expense or judgment of any kind whatsoever (including the reasonable fees and expenses of counsel) ( 1 ) caused by the willful misconduct, gross negligence or bad faith of the Trustee or ( 2 ) arising out of any information furnished in writing to the Sponsor by the Trustee expressly for use in the registration statement, or any amendment thereto or periodic report, filed with the SEC relating to the Shares that is not materially altered by the Sponsor. The Trust Agreement provides that the Sponsor and its shareholders, directors, officers, employees, affiliates (as such term is defined under the Securities Act of 1933, as amended) and subsidiaries and agents shall be indemnified from the Trust and held harmless against any loss, liability, claim, cost, expense or judgment of any kind whatsoever (including the reasonable fees and expenses of counsel) arising out of or in connection with the performance of their obligations under the Trust Agreement or any actions taken in accordance with the provisions of the Trust Agreement and incurred without their ( 1 ) willful misconduct, gross negligence or bad faith or ( 2 ) reckless disregard of their obligations and duties under the Trust Agreement. The Trust has agreed that the Cash Custodian will only be responsible for any loss or damage suffered by the Trust as a direct result of the Cash Custodian’s negligence, fraud or willful default in the performance of its duties. The Trust’s maximum exposure under these arrangements is unknown because it involves future potential claims against the Trust, which cannot be predicted with any certainty. 6 - Commitments and Contingent Liabilities In the normal course of business, the Trust may enter into contracts with service providers that contain general indemnification clauses. The Trust’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Trust, that have not yet occurred. 7 - Concentration Risk Substantially all of the Trust’s assets are holdings of ether, which creates a concentration risk associated with fluctuations in the price of ether. Accordingly, a decline in the price of ether will have an adverse effect on the value of the Shares of the Trust. Factors that may have the effect of causing a decline in the price of ether include negative perception of digital assets; a lack of stability and standardized regulation in the digital asset markets; the closure or temporary shutdown of digital asset platforms due to fraud, business failure, security breaches or government mandated regulation; and a loss of investor confidence. F- 13 Table of Contents 8 - Financial Highlights The following financial highlights relate to investment performance and operations for a Share outstanding for the year ended December 31, 2025 and the period from May 21, 2024 ( Date of Seeding) to December 31, 2024.

(g) Percentage is annualized. 9 - Investment Valuation U.S. GAAP defines fair value as the price the Trust would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The Trust’s policy is to value its investment at fair value. Various inputs are used in determining the fair value of assets and liabilities. Inputs may be based on independent market data (“observable inputs”) or they may be internally developed (“unobservable inputs”). These inputs are categorized into a disclosure hierarchy consisting of three broad levels for financial reporting purposes. The level of a value determined for an asset or liability within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement in its entirety. The three levels of the fair value hierarchy are as follows: Level 1  − Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2 −  Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means; and Level 3 −  Unobservable inputs that are unobservable for the asset or liability, including the Trust’s assumptions used in determining the fair value of investments. At December 31, 2025 and December 31, 2024 the value of the ether held by the Trust is categorized as Level 1.
