Grayscale Bitcoin Mini Trust ETF to adopt CoinDesk Bitcoin Benchmark Rate for NAV effective April 1, 2026
--------------------------------------------------------------------------------

- As of April 1, 2026, Trust will value Bitcoin holdings using the CoinDesk Bitcoin Benchmark Rate, replacing the CoinDesk Bitcoin Price Index (XBX).
- The new index aggregates trade data from 11 licensed platforms including Binance, Kraken, Gemini, and Crypto.com.
- If the benchmark is unavailable, the Sponsor uses a cascading fallback: Coin Metrics Secondary Index, then a principal market price, then a good-faith estimate.
- The Sponsor believes the new methodology provides a more accurate picture of Bitcoin price movements and reduces impact of anomalous trading.
