**a quorum is present at the Annual Meeting. If a quorum is not present, the meeting may be adjourned until a quorum is obtained. There were 44,124,394 shares of common stock outstanding and entitled to vote on April 15, 2025, our record date. Therefore, a quorum will be present if 44,124,395 shares of our common stock are present in person or represented by executed proxies timely received by us at the Annual Meeting. Shares present virtually during the Annual Meeting will be considered shares of common stock represented in person at the meeting.

How is the vote counted?

Under our bylaws, to be elected, each of the directors nominated in Proposal No. 1 must receive a plurality of the shares present in person, by remote communication, if applicable, or represented by proxy duly authorized at the meeting and entitled to vote generally on the election of directors, meaning that the director nominees receiving the highest number of affirmative votes will be elected as directors. You may vote for all the director nominees, withhold authority to vote your shares for all the director nominees or withhold authority to vote your shares with respect to any one or more of the director nominees. Withholding authority to vote your shares with respect to one or more director nominees will have no effect on the election of directors. Broker non-votes are not considered votes cast and will have no effect on the election of directors.

Under our bylaws, any proposal other than an election of directors is decided by the affirmative vote of a majority of shares properly cast for and against such matter, except where a larger vote is required by law or by our Fifth Amended and Restated Certificate of Incorporation (the “certificate of incorporation”), or our bylaws. Abstentions and broker “non-votes” will be treated as shares present for the purpose of determining the presence of a quorum for the transaction of business at the Annual Meeting, but will not be counted as votes cast and will have no effect on the outcome of the vote for such proposal. A broker “non-vote” occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item, and has not received instructions from the beneficial owner.
