The final voting results of voting on each of the proposals submitted to stockholders at the Annual Meeting are as follows:

Proposal 1 - Elect 10 directors to serve until the 2026 annual meeting of stockholders and until their successors are elected and qualified.

Consistent with the recommendation of the Board of Directors of the Company set forth in the Company’s proxy statement for the 2026 Annual Meeting (the “2026 Proxy Statement”), and the majority vote of the Company’s stockholders at the 2026 Annual Meeting, the Company will include an annual advisory vote on the compensation of its NEOs in its proxy materials until the next required stockholder vote on the frequency of future advisory votes on executive compensation, which vote is expected to be held in six years at the Company’s 2032 Annual Meeting of Stockholders. Accordingly, the next shareholder advisory (non-binding) vote on executive compensation of NEOs will be held at the Company’s 2027 Annual Meeting of Stockholders.

Proposal 5 - Ratify the appointment of Forvis Mazars, LLP, as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026.
