On December 19, 2025, the Board of Directors (the “Board”) of ETHZilla Corporation (the “Company”, “we” and “us”), with the recommendation of the Nominating and Corporate Governance Committee of the Board, appointed Angela Dalton and Michael Edwards (collectively, the “Appointees”) as members of the Board, effective immediately (the “Appointments”). In connection with the Appointments, the Company entered into offer letters with each of Ms. Dalton and Mr. Edwards, which provide for compensation for services as a non-employee director consistent with the compensation generally provided to our other non-employee directors.

Both Ms. Dalton and Mr. Edwards were appointed as Class I directors of the Company, and will serve as directors until the Company’s 2027 Annual Meeting of Stockholders and until each of their successors has been duly elected and qualified, or until their earlier death, resignation or removal.

At the same time, the Board, pursuant to the power provided to the Board by the Company’s Second Amended and Restated Certificate of Incorporation, as amended, set the number of members of the Board at seven (7) members.

There are no family relationships between Ms. Dalton or Mr. Edwards and any director or executive officer of the Company.

Upon their appointment to the Board, Ms. Dalton was appointed as a Member of the Audit Committee and as Chairperson of the Compensation Committee (replacing Mr. Andrew Suckling, who will remain on the Compensation Committee as a Member), and Mr. Edwards was appointed as a member of the Nominating and Corporate Governance Committee.

Neither Ms. Dalton nor Mr. Edwards is a party to any material plan, contract or arrangement (whether or not written) with the Company, and there are no arrangements or understandings between Ms. Dalton or Mr. Edwards and any other person pursuant to which Ms. Dalton and Mr. Edwards were selected to serve as a director of the Company, nor are Ms. Dalton or Mr. Edwards a participant in any related party transaction required to be reported pursuant to Item 404(a) of Regulation S-K.
