In connection with the 2026 Annual Meeting, we published our Proxy Statement, a copy of which may be found by clicking here.\n\nThe Proxy Statement contains a series of proposals for our shareholders to consider and on which we ask our shareholders to vote. It also contains our Board’s recommendation as to how to vote on each proposal.\n\nI am writing to encourage you to exercise your rights as a shareholder of Alkermes and vote your Alkermes shares before our 2026 Annual Meeting, which is being held next Wednesday, May 20, 2026. All employees who owned shares of Alkermes on March 13, 2026 (known as the ‘Record Date’ for the Annual Meeting) are entitled to vote.\n\nYour vote is very important to Alkermes, and we encourage you to vote as soon as possible. To be counted, your vote must be received by Tuesday, May 19, 2026 at 11:59 p.m. ET (4:59 a.m. IST).\n\nIf you have any questions about the proposals in the Proxy Statement or how to vote your shares, please feel free to reach out.\n\nThank you for your support."}
