Grayscale Ethereum Classic Trust (ETC) (trading under the symbol ETCG) is a statutory trust structure that issues shares referred to in SEC filings as "Grayscale Ethereum Classic Trust (ETC) Shares." According to its registration under Section 12(g) of the Securities Exchange Act of 1934, these shares trade under the symbol ETCG, while the exchange field in recent filings is listed as "N/A." The trust has a sponsor, Grayscale Investments Sponsors, LLC, which is responsible for managing and directing the affairs of the trust as described in its SEC reports.

The trust is associated with Ethereum Classic (ETC) through its name and through references in its filings to the "ETC industry and market" and to the "CoinDesk Ether Classic Price Index (ECX)." The index is used to derive an "Index Price" for Ethereum Classic, and the trust’s public disclosures reference this index in the context of its business overview. The trust’s structure and disclosures are documented in its annual reports on Form 10-K and current reports on Form 8-K filed with the Securities and Exchange Commission.

Trust structure and sponsorship

Grayscale Ethereum Classic Trust (ETC) identifies Grayscale Investments Sponsors, LLC as its sponsor. The sponsor is, in turn, part of a broader corporate structure involving Grayscale Operating, LLC and Grayscale Investments, Inc. In an internal corporate reorganization described in a Form 8-K dated October 22, 2025, Grayscale Investments, Inc. became the sole managing member of Grayscale Operating, LLC, which is the sole member of the sponsor. The filings state that this reorganization is not expected to have a material impact on the operations of the trust.

These entities are consolidated subsidiaries of Digital Currency Group, Inc., as disclosed in the same filing. The sponsor’s board-level oversight shifted from GSO Intermediate Holdings Corporation to the board of Grayscale Investments, Inc. as part of that reorganization, with the board of Grayscale Investments assuming responsibility for managing and directing the affairs of the sponsor.

Index and market reference

The trust’s filings refer to the CoinDesk Ether Classic Price Index (ECX) as an index used to calculate an Index Price for Ethereum Classic. A Form 8-K dated September 21, 2025, notes that CoinDesk Indices, Inc., described as the "Index Provider," conducts scheduled quarterly reviews of the "Digital Asset Trading Platforms" that are used as "Constituent Trading Platforms" in the index.

As of that filing, the Constituent Trading Platforms included Coinbase, Kraken, Bitfinex, and Crypto.com. The same filing explains that the Index Provider may add or remove trading venues that satisfy or fail its criteria and may change the way the Index Price is calculated. Further detail on the index methodology and its role in the trust’s business is referenced in the section "Item 1. Business—Overview of the ETC Industry and Market—ETC Value—The Index and the Index Price" in the trust’s Annual Report on Form 10-K for the year ended December 31, 2024.

Corporate governance and oversight

The governance of the sponsor and related entities is described in several Form 8-K filings. In an 8-K dated October 13, 2025, the sponsor reported changes to the board of directors of GSO Intermediate Holdings Corporation, including the departure of one director and the appointment of another. The filing provides background on the new director’s role at Digital Currency Group, Inc. and other affiliated entities, highlighting that these entities are part of the same broader corporate group as the sponsor.

Another 8-K dated October 22, 2025, explains that DCG Grayscale Holdco, LLC, as the sole stockholder of Grayscale Investments, elected a board of directors at Grayscale Investments in connection with the internal reorganization. This board is responsible for managing and directing the affairs of the sponsor following the reorganization. The filings emphasize continuity by noting that the members of the new board at Grayscale Investments were the same individuals who previously served on the board of GSO Intermediate Holdings Corporation.

Communications and third-party content

A Form 8-K dated December 3, 2025, addresses use of cashtags and third-party content on X (formerly Twitter). In that filing, Grayscale Investments Sponsors, LLC and its affiliates (collectively referred to as "Grayscale") explain that they maintain a presence on X but are not affiliated with X or other social media sites. The filing notes that X automatically converts ticker symbols preceded by a "$" into "cashtags" that link to pages containing market data, news, commentary, and other content created or supplied by third parties.

The trust’s sponsor explicitly states that it does not control, endorse, or assume responsibility for information displayed on those X-generated pages or on third-party websites, data sources, or services accessible through them. The filing cautions that such information may be inaccurate, incomplete, untimely, or inconsistent with Grayscale’s public disclosures and advises investors to rely on the trust’s SEC filings for authoritative and up-to-date information.
