**Item 1.02 Termination of a Material Definitive Agreement.**

On July 22, 2025, Cipher Mining Inc. (the "Company") entered into a Termination Agreement (the "Termination Agreement") with Bitfury Top HoldCo B.V. ("Bitfury") and Bitfury Holding B.V. ("Bitfury Holding") (together with "Bitfury," the "Bitfury Investors"), which terminated that certain Observer Agreement (the "Board Observer Agreement") entered into with the Bitfury Investors on April 8, 2022.

The Board Observer Agreement provided that the Bitfury Investors had the right to designate a representative to serve as a non-voting observer (the "Observer") of the Company's Board of Directors (the "Board") and any committees thereof, the right to attend and observe meetings of the Board, including any meetings of the committees thereof, and to participate in discussions of matters brought to the Board or any committee thereof, in each case, subject to certain exceptions specified in the Board Observer Agreement, and certain information rights. The Bitfury Investors' rights under the Board Observer Agreement would have terminated upon the date that the Bitfury Investors no longer beneficially owned at least 10% of the outstanding shares of the Company's common stock.

Since the Board Observer Agreement's execution, the Bitfury Investors had not designated an Observer or exercised their information rights thereunder, and the Bitfury Investors confirmed they had no intent to designate an Observer or exercise such rights.

As a result of the Termination Agreement, the Board Observer Agreement will be of no further force and effect and neither party shall have further obligations thereunder, effective as of July 22, 2025. The Termination Agreement contains mutual release of claims and obligations, covenants not to sue, and customary confidentiality provisions.
