Four of us were appointed by, or with the public support of, other shareholders who have sought change at the Company.  We represent a large majority on the Board &#x2013; 70% of all independent directors &#x2013; and we hold significant and influential roles across the Board&#x2019;s Audit and Risk, Compensation, Financial Operating and Nominating and Corporate Governance committees.

To that end, we are actively engaged in all areas of the business, including the evaluation of strategic opportunities, R&amp;D and commercial capital allocation decisions, corporate governance enhancements, cost structure oversight, and operational efficiency improvements. We have worked closely with our fellow directors and management on designing, and overseeing the execution of, the Company&#x2019;s Value Enhancement Plan, which was announced in December 2020, and formulating and overseeing execution of the Company&#x2019;s key strategic priorities. We approach this work with an openness to explore new and innovative avenues to unlock the value of the Company&#x2019;s assets.</font><font style="color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:&quot;Calibri&quot;, sans-serif;min-width:fit-content;">  </font></p>

One important example and outcome of this ongoing process is management&#x2019;s implementation, with strong Board support and encouragement, of a rigorous R&amp;D development framework with clearly defined stage-gates and success criteria to prioritize and allocate capital to those R&amp;D programs that we believe have the highest potential ROI. The professionalism, humility and openness of the entire Board and management team to be active participants in this important work, and to drive meaningful change at Alkermes, has been apparent and effective.</font><font style="color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:&quot;Calibri&quot;, sans-serif;min-width:fit-content;"> </font></p>

As part of this process, we, and many other independent directors of the Board, engaged directly and repeatedly with the Sarissa nominees, including through an interview with each nominee.</font></p>

Not electing Dr. Gaynor would be contrary to the best interests of shareholders, as it would cause us to lose key drug development and operational expertise important to the successful execution of our strategy. Dr. Gaynor is a seasoned R&amp;D public company executive with global industry and biopharmaceutical experience across multiple therapeutic disciplines, whose insights and expertise are invaluable to our Board and directly relevant to the Company&#x2019;s long-term strategic focus. As recently appointed independent directors and fellow shareholders, we are unanimous in our recommendation that shareholders vote &#x201c;FOR&#x201d; Dr. Gaynor.</font></p>
