Can I vote my shares by filling out and returning the Notice? No. The Notice identifies the items to be voted on at the Annual Meeting, but you cannot vote by marking the Notice and returning it. The Notice provides instructions on how to vote: by telephone, through the internet, by requesting and returning a printed proxy card or by submitting a ballot electronically at the Annual Meeting. How many votes do I have? On each matter to be voted upon, you have one vote for each share of common stock you own as of April 7, 2025. If I am a stockholder of record and I do not vote, or if I return a proxy card or otherwise vote without giving specific voting instructions, what happens? If you are a stockholder of record and do not vote by telephone, through the internet, by completing the printed proxy card that may be delivered to you or electronically at the Annual Meeting, your shares will not be voted. If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, (1) “FOR” the election of all three nominees for director, (2) “FOR” the ratification of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2025 and (3) “FOR” the advisory approval of our named executive officer compensation. If any other matter is properly presented at the Annual Meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his best judgment. If I am a beneficial owner of shares held in street name and I do not provide my broker or bank with voting instructions, what happens? If you are a beneficial owner of shares held in street name and you do not instruct your broker, bank or other agent how to vote your shares, your broker, bank or other agent may still be able to vote your shares in its discretion. Brokers, banks and other securities intermediaries may use their discretion to vote
