PROPOSAL 1: ELECTION OF DIRECTORS Our board of directors is divided into three classes equal in number, serving staggered three-year terms. As a result, the terms of only approximately one-third of our board members expire at each annual meeting. The current term of our Class III directors will expire at this year’s annual meeting. The term of our Class I directors will expire at the 2026 annual meeting and the term of our Class II directors will expire at the 2027 annual meeting.

Following a review and nomination from our Corporate Governance and Nominating Committee, our board has proposed that the following Class III directors be elected as Class III directors at our 2025 annual meeting of stockholders for a term that will expire at our 2028 annual meeting and until their respective successors are duly elected and qualified.

Accordingly, broker non-votes will not have any effect on the outcome of voting, but abstentions will have the effect of a vote “AGAINST” the applicable nominee. There is no cumulative voting with respect to the election of directors. The board of directors recommends that you vote “FOR” each of
