Item 5.07 Submission of Matters to a Vote of Security Holders

On May 6, 2026, the Company held its Annual Meeting of Stockholders (the “Annual Meeting”). At the Annual Meeting, the Company’s stockholders voted on the three proposals set forth below. A more detailed description of each proposal is set forth in the Company’s Proxy Statement filed with the Securities and Exchange Commission on March 24, 2026.

Proposal 1:To elect eight directors, each to hold office until the Company's 2027 annual meeting of stockholders or until their successors are duly qualified and elected.
Proposal 2:To approve, on an advisory basis, the compensation of the Company’s named executive officers.

At the close of business on March 11, 2026, the record date for the Annual Meeting, there were 41,194,018 shares of the Company’s common stock outstanding and entitled to vote at the Annual Meeting (“Common Stock”). As the holders of 38,752,780 shares of Common Stock, having a majority of the votes that could be cast by the holders of all outstanding shares of Common Stock, were represented in person or by proxy at the Annual Meeting, a quorum was present.
