Alkermes plc

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

On February 15, 2024, our board of directors authorized a share repurchase program to repurchase ordinary shares of the Company in an aggregate amount of up to $400.0 million (exclusive of any fees, commissions or other expenses related to such repurchases) from time to time (the “2024 Repurchase Program”). The timing and amount of any share repurchases under the 2024 Repurchase Program will be based on a variety of factors, including but not limited to ongoing assessments of our needs, alternative investment opportunities, the market price of our ordinary shares and general market conditions. The 2024 Repurchase Program has no set expiration date and may be suspended or discontinued at any time. The 2024 Repurchase Program terminates, and supersedes in its entirety, our prior share repurchase program authorized by our board of directors in September 2011. We did not purchase any shares under this program during the three months ended March 31, 2024.

During the three months ended March 31, 2024, we acquired 960,486 of our ordinary shares, at an average price of $29.52 per share, to satisfy withholding tax obligations related to the vesting of employee equity awards.
