(the Index Provider) changed the trading venues used to calculate the CoinDesk Dogecoin Benchmark Rate (the Index) effective January 20, 2026. CoinDesk added Binance (DOGE‑USDC), Gate (DOGE‑USDC) and HashKey (DOGE‑USD) and removed Bitfinex (DOGE‑USD) as constituent trading platforms.

Why It Matters

• The CoinDesk Dogecoin Benchmark Rate (the Index) is used to calculate the Trust’s Index Price. Changes to which exchanges feed that benchmark can alter how the index price is derived, and therefore how GDOG’s NAV and market price track Dogecoin market activity.
• This 8-K is informational — it reports the index venue changes made by the Index Provider; it does not announce changes to the Trust’s structure or management. Investors should note that the Index Provider may continue to adjust constituent venues in future reviews.
