SCHEDULE 13D

This Amendment No. 3 to Schedule 13D (“Amendment No.3”) relates to ordinary shares, par value $0.01 per share (“Common Stock” and, such shares, the “Shares”), issued by Alkermes Public Limited Company, a company incorporated under the laws of Ireland (the “Issuer”), and amends the initial statement on Schedule 13D filed with the Securities and Exchange Commission (the “SEC”) on May 10, 2021 (the “Initial Schedule 13D”), as amended by Amendment No. 1 to Schedule 13D filed on May 27, 2021 (“Amendment No. 1”) and Amendment No. 2 to Schedule 13D filed on September 10, 2021 (“Amendment No. 2” and together with the Initial Schedule 13D and Amendment No. 1, the “Schedule 13D”), on behalf of the Reporting Persons, to furnish the additional information set forth herein. All capitalized terms contained herein but not otherwise defined shall have the meanings ascribed to such terms in the Schedule 13D.
Item 3.  Source or Amount of Funds or Other Consideration. Item 3 of the Schedule 13D is hereby amended to include the following:
The Reporting Persons may be deemed to be the beneficial owner of, in the aggregate, 13,213,000 Shares. The aggregate purchase price of the Shares is approximately $274,351,197. The source of funding for these purchases was the general working capital of the respective purchasers.
Item 4.  Purpose of Transaction. Item 4 of the Schedule 13D is hereby amended to include the following:
Pursuant to the Settlement Agreement described in the Initial Schedule 13D, and following discussions with the Issuer, Sarissa Capital designated Cato T. Laurencin, M.D., Ph.D. to serve as a director on the Board. Dr. Laurencin was appointed to the Board on November 18, 2021. Under the Settlement Agreement, the Issuer is also required to nominate Dr. Laurencin for re-election to the Board at the 2022 annual meeting of shareholders.
The Reporting Persons believe the nomination of Dr. Laurencin is a positive outcome for shareholders. The Reporting Persons expect that he will provide a fresh perspective to the Board and are confident he will work with other Board members to focus on optimal capital allocation and operational excellence for the benefit of all shareholders. The Reporting Persons intend to continue discussions with the Issuer and other interested parties regarding Board composition, governance, operations and other matters.
Item 5.  Interest in Securities of the Issuer. Items 5 (a) and (b) of the Initial Schedule 13D are hereby amended and restated as follows:
(a) The Reporting Persons may be deemed to beneficially own, in the aggregate, 13,213,000 Shares representing approximately 8.17% of the outstanding Shares, based upon the 161,705,367 Shares outstanding as of October 22, 2021, as set forth in the Form 10-Q of the Issuer filed with the U.S. Securities and Exchange Commission on October 27, 2021.

(b) For purposes of this Schedule 13D:

All of the Shares for which Sarissa Capital and Dr. Denner may be deemed to beneficially own are held directly by the Sarissa Funds. Sarissa Capital, as the investment advisor to the Sarissa Funds, may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) the Shares held directly by the Sarissa Funds. By virtue of his position as the Chief Investment Officer of Sarissa Capital and by virtue of his control of the ultimate general partner of Sarissa Capital, Dr. Denner may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) the Shares held directly by the Sarissa Funds.
