  1. ELECTION OF DIRECTORS

    ELECTION OF DIRECTORS

  2. General

    General Our Board currently consists of ten directors. Our amended and restated certificate of incorporation (our certificate of incorporation) provides for a classified Board divided into three classes of directors. Class III currently consists of three directors, each of whom has been nominated and is standing for re-election at the Annual Meeting. Classes I and II currently consist of four directors and three directors, respectively. Each class serves a staggered three-year term. At each annual meeting of stockholders, the successors to directors whose terms then expire are elected to serve from the time of election and qualification until the third annual meeting following their election. Vacancies on our Board may be filled only by an affirmative vote of a majority of the directors then in office. A director elected by our Board to fill a vacancy in a class, including vacancies created by an increase in the number of directors, serves for the remainder of the full term of that class and until the director’s successor is duly elected and qualified. Our Board has nominated the three individuals listed in the table below for election as Class III directors at the Annual Meeting. If our stockholders elect the nominees listed below, they will hold office until the 2027 annual meeting of stockholders or until their respective successors have been duly elected and qualified. All nominees are currently serving on our Board and have consented to being named in this proxy statement and to serve if elected. Proxies may not be voted for any nominees other than those named below. If any nominee is unable or does not qualify to serve, you or your proxy may vote for another nominee proposed by our Board. If for any reason any of these nominees proves unable or unwilling to stand for election or ceases to qualify to serve as a director, our Board will nominate an alternate or reduce the size of our Board to eliminate any resulting vacancies. Our Board has no reason to believe that any of the nominees would prove unable to serve if elected. There are no arrangements or understandings between us and any director, or nominee for directorship, pursuant to which such person was selected as a director or nominee. We seek directors with a broad range of qualifications, skills, and experience that would enhance Board effectiveness and strengthen our Board’s ability to carry out its oversight role on behalf of stockholders. Though we do not have a specific policy with respect to Board diversity, we consider diversity as one of many relevant factors when evaluating potential directors. As further described below, we consider diversity broadly when evaluating potential directors and may also consider factors such as a candidate’s relevant academic expertise and business or career experience, including experience in corporate management or as a board member or executive officer of another publicly traded company, to be relevant. In addition, we seek directors who have a high level of personal and professional integrity, strong ethics and values, and the ability to make mature, independent business judgments.

  18. Board of Directors

    Board of Directors Our Board oversees our business and monitors the performance of our management. In accordance with our corporate governance procedures, our Board does not involve itself in our day-to-day operations. Our executive officers and management are responsible for the conduct and oversight of our day-to-day operations. Our directors fulfill their duties and responsibilities by preparing for, attending, and actively participating in meetings of our Board and the respective committees of our Board on which they serve, including by reviewing relevant materials provided in advance of each meeting and making themselves available to management between Board and committee meetings as needed. Our independent directors meet in executive sessions without management or any non-independent directors at least quarterly to consider such matters as they deem appropriate. The Chairman of the Board may call additional executive sessions of the independent directors at any time, and the Chairman of the Board must call an executive session at the request of a majority of the independent directors. The purpose of these executive sessions is to promote open and candid discussion among our independent directors. During the year ended December 31, 2023, our Board held six meetings, our audit committee held four meetings, our compensation and talent committee (compensation committee) held six meetings, and our nominating and corporate governance committee held two meetings. In 2023, each incumbent director attended at least 75% of the total meetings of our Board and the committee(s) on which that particular director served. We encourage our directors to attend each annual meeting of stockholders. Three of our then-current directors attended our 2023 annual meeting of stockholders.
