On November 6, 2025, Daniel Wolf resigned from the Company’s Board of Directors (the “Board”) and any committees thereof. Mr. Wolf’s resignation was not the result of any disagreement between him and the Company or its management.

On November 6, 2025, the Company and Mr. Wolf (through an entity wholly owned by him) entered into a consulting agreement (the “Consulting Agreement”), pursuant to which Mr. Wolf will provide consulting services to support the Company’s efforts relating to marketing, strategy, business development and other corporate matters. The Consulting Agreement provides for, among other terms and conditions: (a) a consulting period of 12 months; (b) acceleration of vesting of the 8,675 shares of restricted stock units granted to Mr. Wolf on June 5, 2025 such that all shares pursuant to such grant are fully vested as of November 6, 2025; and (c) cash compensation at the hourly rate set forth in applicable statements of work accepted by him.

The foregoing descriptions of the Consulting Agreement are qualified in their entirety by the full text of such agreement, a copy of which will be filed as an exhibit to the Company’s quarterly report on Form 10-Q for the quarter ended September 30, 2025.
