. In addition, the development and commercialization of diagnostics is complex and requires significant expertise. By its very nature, a classified board ensures that at any given time there will be experienced directors serving on our Board who are fully immersed in and knowledgeable about our highly technical business, including our relationships with our current and potential strategic partners, as well as the competition, opportunities, risks and challenges that exist in the industry. Each year the Nominating and Corporate Governance Committee reviews the qualifications and performance of the directors prior to nominating them for re-election. We believe the benefit of a classified board to the Company and our stockholders comes not from continuity alone—but rather from the continuity of highly qualified, engaged and knowledgeable directors focused on long-term stockholder interests.

• Unsolicited Takeover Protection. A classified board can reduce vulnerability to potential abusive takeover tactics by encouraging persons seeking control of the Company to negotiate with the Board, thereby strengthening the Board’s ability to negotiate effectively on behalf of all stockholders. Because less than a majority of directors stand for election at each annual meeting under a classified board structure, a hostile bidder could not simply replace a majority of the Board at a single annual meeting with directors aligned with the hostile bidder’s own interests. Rather, in the interests of fairness to stockholders as a whole, having a classified board encourages the hostile bidder to negotiate directly with the Board on a potential transaction.

In summary, we believe the Company has benefited from the independence and continuity of experienced leadership provided by our Board under its classified structure. We will continue to assess our Board’s structure, consider stockholder feedback and make changes when appropriate.

With the assistance of the Nominating and Corporate Governance Committee, our Board regularly reviews its composition, including factors such as professional expertise, industry experience, and diversity of backgrounds. Our Board diversity includes 38% women and 13% underrepresented as of April 9, 2025.

Our Nominating and Corporate Governance Committee is responsible for assessing the appropriate balance of integrity, experience, judgment, commitment (including having sufficient time to devote to the Company and level of participation), skills, diversity and expertise required of the Board. In this regard, the Nominating and Corporate Governance Committee identifies and evaluates individuals qualified, based on self-identified skills and experience disclosed voluntarily by each director, to serve as Board members, including evaluating incumbent directors for re-election, and recommends to the Board nominees for
