At the Meeting, the stockholders holding an aggregate of 3,375,072 shares of Common Stock entitled to vote at the Meeting were represented in person or by proxy, representing approximately 60.85% of the outstanding shares of Common Stock, and thereby a quorum was present for the Meeting.

The final results for each of the proposals considered at the Meeting are set forth below, as certified by the inspector of elections for the Meeting. These proposals are described in further detail in the Definitive Proxy Statement on Schedule 14A filed by the Company with the U.S. Securities and Exchange Commission on April 20, 2026 (the "Proxy Statement")

The proposal to approve the compensation of the Company's named executive officers, as disclosed in the Proxy Statement ("Proposal No. 3"), was approved on an advisory basis by a majority of the shares present in person or by proxy and entitled to vote at the Meeting. This vote is not binding on the Company. However, the compensation committee of the Company's board of directors will consider the outcome of Proposal No. 3 when considering future executive compensation arrangements.

<u>For</u> <u>Against</u> <u>Abstentions</u> <br> 3,077,059 85,755 212,258
