As previously disclosed in a Current Report on Form 8-K filed by the Company with the Securities and Exchange Commission on June 4, 2026, Kavita Mahtani resigned as a Class I Director effective as of June 11, 2026, the date of the Company's 2026 Annual Meeting of Stockholders. As a result, the size of the Board of Directors (the "Board") of the Company was reduced from ten directors to nine directors, resulting in four Class III Directors, three Class II Directors and two Class I Directors. In order to rebalance the class sizes to be as nearly equal in number as possible as required by the Company's Amended and Restated Certificate of Incorporation, as amended, the Board determined that one of its directors should be reclassified from Class III (with a term expiring at the Company's 2029 annual meeting of stockholders) to Class I (with a term expiring at the Company's 2027 annual meeting of stockholders).

Accordingly, effective June 11, 2026, Colin Angle, a member of the Board, resigned from his position as a Class III Director solely for purposes of reclassification, subject to and conditioned upon his immediate reappointment as a Class I Director. The Board accepted Mr. Angle's resignation and immediately reappointed him as a Class I Director, to serve in such capacity until the Company's 2027 annual meeting of stockholders or until his successor is duly elected and qualified, or his earlier death, resignation, or removal. Following Mr. Angle's resignation and reappointment described above, the Board consists of three Class I Directors, three Class II Directors and three Class III Directors.

The resignation and reappointment of Mr. Angle was effected solely for the purpose of reclassifying the members of the Board into three classes of equal size, and for all other purposes, Mr. Angle's service on the Board is deemed to have continued uninterrupted. There were no changes to Mr. Angle's committee assignments or compensation as a non-employee director as a result of the resignation as a Class III Director and appointment as a Class I Director.
