Rhea-AI Filing Summary

CoinDesk Indices, Inc. (the “Index Provider”) announced a change to the Digital Asset Trading Platforms used to derive the Index Price (collectively, “Constituent Trading Platforms”) for Grayscale Zcash Trust (ZEC) (the “Trust”). Effective December 21, 2025, the Index Provider removed Bitfinex from the CoinDesk Zcash Price Index (ZCX) (the “Index”) due to the trading platform failing to meet the Index Provider’s minimum liquidity requirement, and did not add any Constituent Trading Platforms as part of its scheduled quarterly review. As of the date of this current report, the Constituent Trading Platforms included in the Index are Coinbase, Kraken and Gemini.

The Index Provider may change the trading venues that are used to calculate the Index Price, or otherwise change the way in which an Index Price is calculated, at any time.
