 the Board should be held by the same or different individuals. Our Bylaws allow the Board flexibility to determine from time to time whether the two roles should be combined or separated based upon circumstances existing at such time. The Board believes Mr. Yemin’s service as Board Chairman allows him to support the CEO and to lead the Board in overseeing strategy. In light of these factors, combined with Mr. Yemin’s leadership skills, extensive history with the Company and industry expertise, the Board believes his holding the role of Chairman is in the best interest of the Company and its stockholders at this time. The Nominating and Corporate Governance Committee and the Board will continue to periodically evaluate our leadership structure, including these roles, in the future. Because the Chairman of the Board is not an independent director, the Board considers it to be useful and appropriate to designate an independent director to serve in a lead capacity (the “Lead Independent Director”) to coordinate the activities of the other independent directors and to perform such other duties and responsibilities as the Board may determine from time to time. The Lead Independent Director is appointed annually by a majority of the independent directors on the Board and may be removed from or replaced in that position by a majority of the independent directors at any time. Mr. Finnerty has served as the Board’s Lead Independent Director since May 2023. The Lead Independent Director chairs all meetings of the Board at which the Chairman is not present, including executive sessions of the independent directors, can call additional

meetings of the independent directors as deemed appropriate, and performs such other functions as the Board may direct, including: (i) serving as principal liaison between the independent directors, on one hand, and the Chairman and senior management, on the other hand; (ii) providing input from the Board and make recommendations to the Chairman regarding Board meetings including with respect to meeting frequency, dates, locations, agendas, management participation and other matters; and (iii) consulting with the Chairman regarding information submitted by our management that is necessary or appropriate for the Board’s deliberations. In addition, the Lead Independent Director has the authority to engage in direct communication, as appropriate, with our major stockholders, and engage outside counsel and consultants.
