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 the special considerations discussed below, general economic, market and business conditions, changes in laws or regulations, including those concerning taxes, made by governmental authorities or regulatory bodies, and other world economic and political developments. Although the Sponsor does not make forward-looking statements unless it believes it has a reasonable basis for doing so, the Sponsor cannot guarantee their accuracy. Except as required by applicable disclosure laws, neither the Trust nor the Sponsor is under a duty to update any of the forward-looking statements to conform such statements to actual results or to a change in the Sponsor’s expectations or predictions.

Introduction

The iShares Ethereum Trust ETF (the “Trust”) is a Delaware statutory trust. The Trust does not have any officers, directors, or employees and is administered by the Third Amended and Restated Trust Agreement dated as of July 8, 2025, among iShares Delaware Trust Sponsor LLC (the “Sponsor”), BlackRock Fund Advisors (the “Trustee”) and Wilmington Trust, National Association, a national association (the “Delaware Trustee”). The Trust issues shares (“Shares”) representing fractional undivided beneficial interests in its net assets. The assets of the Trust consist primarily of ether held by a custodian on behalf of the Trust.

The Trust is a passive investment vehicle and 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 Trust does not engage in any activities designed to obtain a profit from, or ameliorate losses caused by, changes in the price of ether.

The Trust issues and redeems Shares only 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). Only registered broker-dealers that have previously entered into an agreement with the Sponsor governing the terms and conditions of such transactions (such broker-dealer, 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.

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 Coinbase Inc. (the “Prime Execution Agent”) acting in an agency capacity with third parties through its Coinbase Prime service pursuant to the Prime Execution Agent Agreement.

Shares of the Trust trade on the Nasdaq Stock Market LLC (“NASDAQ”) under the ticker symbol ETHA.

Valuation of Ether; The CF Benchmarks Index

On each day other than a Saturday or a Sunday, or a day on which NASDAQ is closed for regular trading (a “Business Day”), as soon as practicable after 4:00 p.m. Eastern Time (“ET”), the Trust evaluates the ether held by the Trust as reflected by the CME CF Ether–Dollar Reference Rate – New York Variant for the ether – U.S. Dollar trading pair (the “CF Benchmarks Index”) and determines the net asset value of the Trust and the net asset value per Share (“NAV”).

The CF Benchmarks Index is calculated as of 4:00 p.m. ET. The CF Benchmarks Index is designed based on the IOSCO Principles for Financial Benchmarks and is a Registered Benchmark under the UK Benchmark Regulations (“BMR”). The administrator of the CF Benchmarks Index is CF Benchmarks Ltd., a UK incorporated company, authorized and regulated by the Financial Conduct Authority of the UK as a Benchmark Administrator under the UK BMR.

Liquidity

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. In exchange for a fee, the Sponsor has agreed to assume most of the expenses incurred by the Trust. As a result, the only ordinary expense of the Trust during the period covered by this report was the Sponsor’s fee. The Trust’s only source of liquidity is its sales of ether.

Critical Accounting Policies

The financial statements and accompanying notes are prepared in accordance with U.S. GAAP in the United States. The preparation of these financial statements relies on estimates and assumptions that impact the Trust’s financial position and results of operations. These estimates and assumptions affect the Trust’s application of accounting policies. A description of the valuation of ether, a critical accounting policy that the Trust believes is important to understanding its results of operations and financial position, is provided in the section entitled “Valuation of Ether; The CF Benchmark Index,” above. In addition, please refer to Note 2 to the financial statements included in this report for further discussion of the Trust’s accounting policies.

Results of Operations

The Quarter Ended March 31, 2026

The Trust’s net asset value decreased from $10,300,756,520 at December 31, 2025 to $6,378,405,156 at March 31, 2026, a 38.08% decrease. The decrease in the Trust’s net asset value resulted primarily from a decrease in the price of ether, which fell 29.27% from $2,971.55 at December 31, 2025 to $2,101.84 at March 31, 2026. The decrease in the Trust’s net asset value was also affected by a decrease in the number of outstanding Shares, which fell from 458,720,000 Shares at December 31, 2025 to 401,880,000 Shares at March 31, 2026, a consequence of 74,680,000 Shares (1,867 Baskets) being created and 131,520,000 Shares (3,288 Baskets) being redeemed during the quarter. 

The 29.34% decrease in the NAV for purposes of the Trust’s periodic financial statements (“Financial Statement NAV”) from $22.46 at December 31, 2025 to $15.87 at March 31, 2026 is directly related to the 29.27% decrease in the price of ether. The Financial Statement NAV decreased slightly more than the price of ether on a percentage basis due to the Sponsor’s fee, which was $4,969,537 for the quarter, or 0.06% of the Trust’s average weighted assets of $8,064,642,007 during the quarter.

The NAV of $25.50 on January 14, 2026 was the highest during the quarter, compared with a low during the quarter of $14.01 on February 23, 2026.

The net decrease in net assets resulting from operations for the quarter ended March 31, 2026 was $2,996,490,501, resulting from a net realized loss of $3,289,963 from ether sold to pay expenses, a net realized loss of $737,719,591 from ether sold for the redemption of Shares, a net realized loss of $191,019,080 from ether paid for the in-kind redemptions of Shares, an unrealized loss on investment in ether of $2,059,492,330 and a net investment loss of $4,969,537. Other than the Sponsor’s fee of $4,969,537, the Trust had no expenses during the quarter.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Not applicable.

Item 4. 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 March 31, 2026, 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.

There were no changes in the Trust’s internal control over financial reporting that occurred during the quarter ended March 31, 2026 that have materially affected, or are reasonably likely to materially affect, the Trust’s internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings.

None.

Item 1A. Risk Factors

Except as set forth below, there have been no material changes to the Risk Factors last reported under Part I, Item 1A of the registrant’s Annual Report on Form 10-K for the year ended December 31, 2025, filed with the Securities and Exchange Commission on February 27, 2026.

A determination that ether or any other digital asset is a “security” may adversely affect the value of ether and the value of the Shares, and result in potentially extraordinary, nonrecurring expenses to, or termination of, the Trust.

Depending on its characteristics, a digital asset may be considered a “security” under the federal securities laws. The test for determining whether a particular digital asset is a “security” is complex and difficult to apply, and the outcome is difficult to predict. Public, though non-binding, statements made in the past by senior officials at the SEC and endorsed by its previous Chairman in a letter to a member of Congress appeared to indicate that the SEC did not consider ether to be a security at that time. The SEC staff has reportedly provided informal assurances in the past to a handful of promoters that their digital assets are not securities. On the other hand, the SEC has brought enforcement actions against the issuers and promoters of several other digital assets on the basis that the digital assets in question are securities. The CFTC has for years considered ether to be a commodity subject to its regulatory jurisdiction, and ether futures have been listed for years on CFTC‑regulated exchanges while cleared ether swaps have been listed for trading on CFTC‑regulated swap execution facilities not registered with the SEC without being deemed “mixed swaps” subject to joint CFTC and SEC jurisdiction to the Sponsor’s knowledge.

Whether a digital asset is a security under the federal securities laws depends on whether it is included in the lists of instruments making up the definition of “security” in the Securities Act, the Exchange Act and the Investment Company Act. Digital assets as such do not appear in any of these lists, although each list includes the terms “investment contract” and “note,” and the SEC has typically analyzed whether a particular digital asset is a security by reference to whether it meets the tests developed by the federal courts interpreting these terms, known as the Howey and Reves tests, respectively. For many digital assets, whether or not the Howey or Reves tests are met is difficult to resolve definitively, and substantial legal arguments can often be made both in favor of and against a particular digital asset qualifying as a security under one or both of the Howey and Reves tests. Adding to the complexity, the SEC staff has indicated that the security status of a particular digital asset can change over time as the relevant facts evolve.

On March 17, 2026, the SEC issued an interpretive release (the “Interpretive Release”) regarding the application of the federal securities laws to certain types of digital assets and certain transactions involving digital assets. In the Interpretive Release, the SEC stated that, based on its current understanding of the digital asset markets, ether is a “digital commodity” and not itself a security. Although the Interpretive Release represents the official position of the SEC, it is not itself a statute or binding rule, does not supersede or replace the Howey test, is based on the SEC’s current understanding of the digital asset markets, and may be refined, revised or expanded. In addition, a court, regulator, or future administration could take a different view, and future legislation, rulemaking, enforcement positions, judicial decisions or other developments could result in ether, the Trust, the Shares or transactions involving ether being treated differently than contemplated by the Interpretive Release. Any such developments could adversely affect the Trust and the value of the Shares.

As part of determining whether ether is a security for purposes of the federal securities laws, the Sponsor takes into account a number of factors, including the various definitions of “security” under the federal securities laws and federal court decisions interpreting elements of these definitions, such as the U.S. Supreme Court’s decisions in the Howey and Reves cases, as well as reports, orders, press releases, public statements and speeches by the SEC and its staff providing guidance on when a digital asset may be a security for purposes of the federal securities laws, and other materials relevant to the status of ether as a security (or not). Finally, the Sponsor discusses the security status of ether with its securities lawyers. Through this process the Sponsor believes that it is applying the proper legal standards in making a good faith determination that it believes ether is not presently a security under federal law notwithstanding the uncertainties inherent in the Howey and Reves tests. In light of these uncertainties and the fact-based nature of the analysis, the Sponsor acknowledges that ether may currently be a security, based on the facts as they exist today, or may in the future be found by the SEC or a federal court to be a security under the federal securities laws notwithstanding the Sponsor’s prior conclusion; and the Sponsor’s prior conclusion, even if reasonable under the circumstances and made in good faith, would not preclude legal or regulatory action based on the presence of a security.

The Sponsor may dissolve the Trust if the Sponsor determines ether is a security under the federal securities laws, whether that determination is initially made by the Sponsor itself, or because the SEC or a federal court subsequently makes that determination. Because the legal tests for determining whether a digital asset is or is not a security often leave room for interpretation, for so long as the Sponsor believes there to be good faith grounds to conclude that the Trust’s ether is not a security, the Sponsor does not intend to dissolve the Trust on the basis that ether could at some future point be determined to be a security.

Any enforcement action by the SEC or a state securities regulator asserting that ether is a security, or a court decision to that effect would be expected to have an immediate material adverse impact on the trading value of ether, as well as the Shares. This is because the business models behind most digital assets are incompatible with regulations applying to transactions in securities. The New York Attorney General alleged in a lawsuit filed in March 2023 that ether was a security under New York and federal securities law and that a crypto asset platform that deals in ether, unlawfully failed to register as a securities dealer under New York state law. However, the New York Attorney General alleged in the alternative in the same case that ether was a commodity under both New York state and federal law.

If a digital asset is determined or asserted to be a security, it is likely to become difficult or impossible for the digital asset to be traded, cleared or custodied in the United States through the same channels used by non-security digital assets, which in addition to materially and adversely affecting the trading value of the digital asset is likely to significantly impact its liquidity and market participants’ ability to convert the digital asset into U.S. dollars. For example, in 2020 the SEC filed a complaint against the issuer of XRP, Ripple Labs, Inc., and two of its executives, alleging that they raised more than $1.3 billion through XRP sales that should have been registered under the federal securities laws, but were not. In the years prior to the SEC’s action, XRP’s market capitalization at times reached over $140 billion. However, in the weeks following the SEC’s complaint, XRP’s market capitalization fell to less than $10 billion, which was less than half of its market capitalization in the days prior to the complaint. Although the SEC and Ripple reached a settlement in August 2025 to resolve the enforcement action and to dismiss their respective court appeals, which has largely been viewed as positive in the digital assets market, there remains continued uncertainty as to the regulatory framework that will be applied by the SEC and courts to digital assets. Such uncertainty may remain until legislation providing a regulatory framework is adopted. There is currently legislation being considered that addresses this regulatory uncertainty, but it is unclear if the proposed legislation will be passed.

In addition, if ether is determined to be a security, the Trust could be considered an unregistered “investment company” under SEC rules, which could necessitate the Trust’s liquidation. In this case, the Trust and the Sponsor may be deemed to have participated in an illegal offering of securities and there is no guarantee that the Sponsor will be able to register the Trust under the Investment Company Act at such time or take such other actions as may be necessary to ensure the Trust’s activities comply with applicable law, which could force the Sponsor to liquidate the Trust.

Moreover, whether or not the Sponsor or the Trust were subject to additional regulatory requirements as a result of any SEC or federal court determination that its assets include securities, the Sponsor may nevertheless decide to terminate the Trust, in order, if possible, to liquidate the Trust’s assets while a liquid market still exists. For example, in response to the SEC’s action against the issuer of XRP, certain significant market participants announced they would no longer support XRP and announced measures, including the delisting of XRP from major digital asset trading platforms. The sponsor of the Grayscale XRP Trust subsequently dissolved this trust and liquidated its assets. If the SEC or a federal court were to determine that ether is a security, it is likely that the value of the Shares would decline significantly, and that the Trust itself may be terminated and, if practical, its assets liquidated.

Regulatory changes or interpretations could obligate the Trust, the Trustee or the Sponsor to register and comply with new regulations, resulting in potentially extraordinary, nonrecurring expenses to the Trust.

Current and future federal or state legislation, CFTC and SEC rulemaking and other regulatory developments may impact the manner in which ether is treated. In particular, although the Interpretive Release classified ether as a “digital commodity” and not a security under the U.S. federal securities laws, ether may nonetheless in the future be classified by the CFTC as a “commodity interest” under the CEA, or a court or a future SEC administration could conclude that ether is a “security” under U.S. federal securities laws notwithstanding the Interpretive Release. The Sponsor, the Trustee and the Trust cannot be certain as to how future regulatory developments will impact the treatment of ether under the law. In the face of such developments, the required registrations and compliance steps may result in extraordinary, nonrecurring expenses to the Trust. If the Trustee decides to terminate the Trust in response to the changed regulatory circumstances, the Trust may be dissolved or liquidated at a time that is disadvantageous to Shareholders.

To the extent that ether is deemed to fall within the definition of a “commodity interest” under the CEA, the Trust, the Trustee and the Sponsor may be subject to additional regulation under the CEA and CFTC regulations. The Sponsor or the Trustee may be required to register as a commodity pool operator or commodity trading adviser with the CFTC and become a member of the National Futures Association (“NFA”) and may be subject to additional regulatory requirements with respect to the Trust, including disclosure and reporting requirements. These additional requirements may result in extraordinary, recurring and/or nonrecurring expenses of the Trust, thereby materially and adversely impacting the Shares. If the Sponsor or the Trustee determines not to comply with such additional regulatory and registration requirements, the Trustee will terminate the Trust. Any such termination could result in the liquidation of the Trust’s ether at a time that is disadvantageous to Shareholders.

To the extent that ether is deemed to fall within the definition of a security under U.S. federal securities laws, the Trust, the Trustee and the Sponsor may be subject to additional requirements under the Investment Company Act and the Sponsor or the Trustee may be required to register as an investment adviser under the Investment Advisers Act. Such additional registration may result in extraordinary, recurring and/or non-recurring expenses of the Trust, thereby materially and adversely impacting the Shares. If the Sponsor or the Trustee determines not to comply with such additional regulatory and registration requirements, the Trustee will terminate the Trust. Any such termination could result in the liquidation of the Trust’s ether at a time that is disadvantageous to Shareholders.
