Grayscale Ethereum Classic Trust (ETC) (ETCG) reports a change in how it values its Ethereum Classic (ETC) holdings and calculates NAV and NAV per share. Effective September 1, 2026, the trust will use the CoinDesk Ethereum Classic Benchmark Extended Rate as its reference index and Index Price.
The filing describes in detail the index’s methodology, including selection criteria for Constituent Trading Platforms, volume-weighted pricing, FX conversion to USD, outlier exclusion, inactivity adjustments, and manipulation-resistance features. It also outlines a cascading backup process for determining the Index Price if the primary index, a secondary Coin Metrics rate, or principal market data become unavailable or are deemed inaccurate, after which the sponsor may use its own good faith estimate.

Masci is also joining the sponsor’s Board of Managers and becomes the Principal Financial and Accounting Officer of the trust. They succeed Edward McGee, who is stepping down after about seven years as Chief Financial Officer for personal reasons, with the company stating there is no disagreement regarding operations, policies, or practices.
Grayscale Ethereum Classic Trust (ETCG) is informing investors how to treat its presence on X (formerly Twitter), especially the use of ticker symbols with a “$” cashtag. When Grayscale-related accounts post cashtags, X automatically links them to pages that aggregate market data, news, and commentary from various third parties.
The trust explains that Grayscale does not control, endorse, or take responsibility for any information on those X-generated pages or other third-party sites reached through them. That content is not authorized or verified by Grayscale and may conflict with its official disclosures. Investors are directed to rely on Grayscale’s Securities and Exchange Commission filings for authoritative and up-to-date information about the trust and its products.
