The 2026 Annual Meeting of the Registrant’s stockholders was held on January 30, 2026. Each of the 25,874,368 shares of common stock entitled to vote at the meeting was entitled to one vote on each matter voted on at the meeting. The affirmative vote of a majority of the shares represented in person or by proxy at the meeting was required to elect each director and to approve each of the other proposals considered at the meeting. The vote totals below are rounded down to the nearest whole share, and Broker Non-Votes are not considered to be entitled to vote on the matter in question and are therefore not counted in determining the number of votes required for approval.

At the meeting, there were 24,259,347 shares represented and entitled to vote on one or more matters at the meeting, or approximately 93.8% of the outstanding shares. The voting on each of the proposals was as follows:

Proposal 1 – Election of Directors (for terms expiring at the 2029 Annual Meeting):

Because each nominee received a majority of the shares represented at the meeting and entitled to vote on the nominee, all of the nominees were duly elected.

Proposal 2 – Advisory vote on the resolution to approve the compensation of the Registrant’s executive officers (“Say on Pay”):

Because the proposal received a majority of the shares represented at the meeting and entitled to vote on the matter, it was duly approved.

Proposal 3 – Amendment to the Company’s Employee Stock Purchase plan as described in the Proxy Statement for the Meeting and attached hereto as Exhibit 10.1:

Because the proposal received a majority of the shares represented at the meeting and entitled to vote on the matter, it was duly approved.

Proposal 4 – Ratification of the Registrant’s appointment of Grant Thornton LLP as the Registrant’s independent registered public accounting firm for the 2026 fiscal year:

Because the proposal received a majority of the shares represented at the meeting and entitled to vote on the matter, it was duly approved.
