Dr. Laurencin has served on the Nominating and Corporate Governance Committee since early 2022. After receiving a second nomination notice from Sarissa in January 2022, the company repeatedly offered to work with Sarissa to identify another mutually agreeable director candidate. In February 2023, the company received a third notice of intention to nominate three director candidates. </p>

The Nominating and Corporate Governance Committee carefully considered their candidacy in light of the Board&#8217;s current composition and alignment with the company&#8217;s business strategy and what the Board believes to be in the best interests of shareholders. Based on these interviews, the Nominating and Corporate Governance Committee&#8217;s evaluation and recommendation, and the assessment of the full Board, the Board did not endorse them for election at the Annual Meeting. Independent directors have reiterated the Board&#8217;s continued openness to finding a resolution that would avoid a contested election and remain in communication with Sarissa and open to Sarissa&#8217;s feedback. </p>

We have established a track record of strong governance practices and board refreshment, with the appointment of seven new independent and highly qualified directors since 2019, four of them appointed in collaboration with shareholders. We are pleased to see the implementation of several shareholder-supported initiatives and execution of the company&#8217;s strategy translate into value creation for shareholders, with the company&#8217;s share price outperforming relevant peers and indices over several recent time periods. We remain focused on strong oversight and taking bold strategic steps to create value and build on the company&#8217;s momentum.&#8221;</p>
