Grayscale Ethereum Staking Mini ETF Changes Index Price

Effective April 1, 2026, the Grayscale Ethereum Staking Mini ETF will change the index price used to value its Ether holdings for operational purposes. The Trust will transition from using the CoinDesk Ether Price Index (ETX) to the CoinDesk Ether Benchmark Rate. This change will impact the calculation of the Trust's Net Asset Value (NAV) and NAV per Share. The CoinDesk Ether Benchmark Rate utilizes a methodology that includes data from various digital asset trading platforms, selected based on criteria such as market quality, security, legal and regulatory compliance, KYC/AML practices, data provision, transparency, team expertise, and avoidance of negative events. The selection process aims to mitigate the effects of fraud, manipulation, and anomalous trading activity by employing a volume-weighted algorithm and outlier detection. In instances where the primary index price is unavailable or deemed inaccurate, a cascading set of backup procedures will be employed, including the use of a secondary index (Coin Metrics Real-Time Rate), a tertiary pricing option from the Trust's principal market, or a good faith estimate by the Sponsor. The Sponsor reserves the right to modify the index calculation methodology or provider at its discretion, with notification provided to shareholders.
