Item 8.01. Other Events.

On March 16, 2026, Grayscale Investments Sponsors, LLC (the “Sponsor”), the sponsor of Grayscale Ethereum Staking Mini ETF (the “Trust”), announced a change to the index price used to value the Trust’s Ether for operational purposes. Effective April 1, 2026, the Trust will value the Ether it holds for operational purposes by reference to the CoinDesk Ether Benchmark Rate. Prior to April 1, 2026, the Trust valued its Ether for operational purposes by reference to the CoinDesk Ether Price Index (ETX). Beginning April 1, 2026, the Trust’s net asset value (“NAV”) and NAV per Share will be calculated using the Index Price based on the CoinDesk Ether Benchmark Rate. Prior to that date, the Trust’s NAV and NAV per Share were calculated using the CoinDesk Ether Price Index (ETX). Accordingly, references to the “Index” in the Trust’s filings with the Securities and Exchange Commission (the “SEC”) refer to the CoinDesk Ether Price Index (ETX) for periods prior to April 1, 2026, and to the CoinDesk Ether Benchmark Rate for periods beginning on and after April 1, 2026.

As of March 16, 2026, the Digital Asset Trading Platforms included in the CoinDesk Ether Benchmark Rate were Binance, Bitstamp by Robinhood, Bullish, Bybit, Crypto.com, Gate, Gemini, HashKey, Kraken, LMAX Digital, and OKX. The Sponsor and the Trust reasonably believe each of these Digital Asset Trading Platforms are in material compliance with applicable licensing requirements based on the inclusion criteria and jurisdiction, as detailed below, and maintain practices and policies designed to comply with anti-money laundering (“AML”) and know-your-customer (“KYC”) regulations.

Capitalized terms used but not defined herein have the meanings ascribed to them in the Trust’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

The Index and the Index Price

The Index is a U.S. dollar-denominated composite reference rate for the price of Ether. The Index is designed to (1) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the Ether reference rate, (2) provide a real-time, volume-weighted fair value of Ether and (3) appropriately handle and adjust for non-market related events.

The Index Price is determined by the Index Provider through a process in which trade data is cleansed and compiled in such a manner as to algorithmically reduce the impact of anomalistic or manipulative trading. This is accomplished by adjusting the weight of each data input based on price deviation relative to the observable set, as well as recent and long-term trading volume at each venue relative to the observable set.

Constituent Trading Platform Selection

Digital Asset Trading Platforms are selected for inclusion in the Index based on a methodology developed by the Index Provider in alignment with the International Organization of Securities Commissions (“IOSCO”) Principles for Financial Benchmarks. To qualify as a Constituent Trading Platform, a platform is evaluated across the following core criteria listed below (the “Inclusion Criteria”):

Trading platforms that meet these Inclusion Criteria are also required to be licensed and able to serve customers in one or more of the following jurisdictions:

A Digital Asset Trading Platform is removed from the Constituent Trading Platforms when it no longer satisfies the Inclusion Criteria. The Index Provider may also exclude certain trading platforms that require additional support from such contributing trading platforms at its discretion. The Index Provider does not currently include data from over-the-counter markets or derivatives platforms among the Constituent Trading Platforms. Over-the-counter data is not currently included because of the potential for trades to include a significant premium or discount paid for larger liquidity, which creates an uneven comparison relative to more active markets. There is also a higher potential for over-the-counter transactions to not be arms-length, and thus not be representative of a true market price. Ether derivative markets are also not currently included. While the Index Provider has no plans to include data from over-the-counter markets or derivative platforms at this time, the Index Provider will consider IOSCO principles for financial benchmarks, the management of trading venues of Ether derivatives and the aforementioned Inclusion Criteria when considering whether to include over-the-counter or derivative platform data in the future.

The Index Provider and the Sponsor have entered into the index license agreement, dated as of February 1, 2022 (as amended, the “Index License Agreement”), governing the Sponsor’s use of the Index Price. Pursuant to the terms of the Index License Agreement, the Index Provider may adjust the calculation methodology for the Index Price without notice to, or consent of, the Trust or its shareholders. The Index Provider may decide to change the calculation methodology to maintain the integrity of the Index Price calculation should it identify or become aware of previously unknown variables or issues with the existing methodology that it believes could materially impact its performance and/or reliability. The Index Provider has sole discretion over the determination of the Index Price and may change the methodologies for determining the Index Price from time to time. Shareholders will be notified of any material changes to the calculation methodology or the Index Price in the Trust’s current reports and will be notified of all other changes that the Sponsor considers significant in the Trust’s periodic or current reports. The Sponsor will determine the materiality of any changes to the Index Price on a case-by-case basis, in consultation with external counsel.

The Index Provider may change the trading venues that are used to calculate the Index or otherwise change the way in which the Index is calculated at any time. For example, the Index Provider has scheduled monthly reviews in which it may add or remove Constituent Trading Platforms that satisfy or fail the Inclusion Criteria as well as other requirements detailed in the Index Methodology. The Index Provider does not have any obligation to consider the interests of the Sponsor, the Trust, the shareholders, or anyone else in connection with such changes. While the Index Provider is not required to publicize or explain the changes or to alert the Sponsor to such changes, it has historically notified the Trust of certain changes to the Constituent Trading Platforms, including any additions or removals of the Constituent Trading Platforms, in addition to issuing press releases in connection with the same. The Sponsor will provide updates of such changes in the Trust’s quarterly reports on Form 10-Q. Although the Index methodology is designed to operate without any manual intervention, rare events would justify manual intervention. Intervention of this kind would be in response to non-market-related events, such as the halting of deposits or withdrawals of funds on a Digital Asset Trading Platform, the unannounced closure of operations on a Digital Asset Trading Platform, insolvency or the compromise of user funds. In the event that such an intervention is necessary, the Index Provider would issue a public announcement through its website, API and other established communication channels with its clients.

Determination of the Index Price

The Index, as reflected by the CoinDesk Ether Benchmark Rate, for Ether is calculated through the application of an algorithm to the price of Ether on the Constituent Trading Platforms calculated every 5 seconds over a 24-hour period. The Index’s algorithm is expected to reflect a five-pronged methodology to calculate the Index Price from the Constituent Trading Platforms for Ether:

The Index Provider re-evaluates the weighting algorithm on a periodic basis, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms.

The Sponsor believes the Index Provider’s selection process for Constituent Trading Platforms as well as the methodology of the Index Price’s algorithm provides a more accurate picture of Ether price movements than a simple average of Digital Asset Trading Platform spot prices, and that the weighting of Ether prices on the Constituent Trading Platforms limits the inclusion of data that is influenced by temporary price dislocations that may result from technical problems, limited liquidity or fraudulent activity elsewhere in the Ether spot market. By referencing multiple trading venues and weighting them based on trade activity, the Sponsor believes that the impact of any potential fraud, manipulation or anomalous trading activity occurring on any single venue is reduced.

If the Index Price becomes unavailable, or if the Sponsor determines in good faith that such Index Price does not reflect an accurate price for Ether, then the Sponsor will contact the Index Provider to obtain the Index Price directly from the Index Provider. If after such contact such Index Price remains unavailable or the Sponsor continues to believe in good faith that such Index Price does not reflect an accurate price for Ether, then the Sponsor will employ a cascading set of rules to determine the Index Price, as described below in “—Determination of the Index Price When Index Price is Unavailable.”

The Trust values its Ether for operational purposes by reference to the Index Price. The Index Price is the value of one Ether as represented by the Index, calculated at 4:00 p.m., New York time, on each business day.

Illustrative Example

For the purposes of illustration, outlined below are examples of how the attributes that impact weighting and adjustments in the aforementioned methodology may be utilized to generate the Index Price for a digital asset.

For example, Constituent Trading Platforms used to calculate the Index Price of the digital asset may include trading platforms such as Crypto.com, Kraken, LMAX Digital and Bitstamp by Robinhood.

The Index Price algorithm, as described above, is designed to account for manipulation at the outset by only including data from executed trades on Constituent Trading Platforms that charge trading fees. Then, the below-listed elements may impact the weighting of the Constituent Trading Platforms on the Index Price as follows:

Determination of the Index Price When Index Price is Unavailable

The Sponsor uses the following cascading set of rules to calculate the Index Price. For the avoidance of doubt, the Sponsor will employ the below rules sequentially and in the order as presented below, should one or more specific rule(s) fail:

In the event of a fork, the Index Provider may calculate the Index Price based on a digital asset that the Sponsor does not believe to be the appropriate asset that is held by the Trust. In this event, the Sponsor has full discretion to use a different index provider or calculate the Index Price itself using its best judgment.

The Sponsor may, in its sole discretion, select a different index provider, select a different index price provided by the Index Provider, calculate the Index Price by using the cascading set of rules set forth above, or change the cascading set of rules set forth above at any time. The Sponsor will provide notice of any such changes in the Trust’s periodic or current reports and, if the Sponsor makes such a change other than on an ad hoc or temporary basis, will file a proposed rule change with the SEC.
