On September 21, 2026, MARA's subsidiary Volt Texas LLC amended its July 2, 2026 agreement to acquire MAT 1177 LLC, which holds land rights and a site for a planned data center project in Texas. The amendment requires a $100.0 million security deposit to the Electric Utility Company, which Buyer may withdraw at its discretion subject to a sale process, and restructures milestone payments while keeping the aggregate purchase price at $600 million if all milestones are achieved. The filing also replaces the provision allowing the membership interests to be returned to the seller with a process to market the project for sale to a third party, with the seller holding a right of first offer.

MARA Holdings said directors Barbara Humpton and Georges Antoun resigned from the board effective July 31, 2026, citing personal reasons and no disagreements with the company. On August 1, 2026, the board appointed Craig Hart and Nancy Novak to fill the two vacancies, with Hart also joining the Risk and Audit Committee. The board will still have seven directors, six of whom are independent, so the change is administrative and does not signal a shift in financial results.
