PART II

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

(iv) The description of the Shares contained in the “Description of Securities” filed as Exhibit 4.1 to the Registrant’s Annual Report on Form 10-K for the year ended December 31, 2024, including any amendment or report filed for the purpose of updating such description.

All documents that the Registrant subsequently files pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act of 1934, as amended, prior to the filing of a post-effective amendment which indicates that all securities offered herein have been sold or which deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference herein and to be part hereof from the date of filing such documents.

Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.

Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Not applicable.

Item 6. Indemnification of Directors and Officers.

The Irish Companies Act 2014 permits a company to pay the costs or discharge the liability of a director or a secretary only where favorable judgment is given in any civil or criminal action in respect of such costs or liability, or where an Irish court grants relief because the director or secretary acted honestly and reasonably and ought fairly to be excused. This restriction does not apply to executives who are not directors or a secretary of the Registrant. Any provision by an Irish company which seeks to indemnify a

director or secretary of that Irish company over and above this shall be void under Irish law, whether contained in such company’s articles of association or any contract between the director or secretary and such company.

Pursuant to the Registrant’s articles of association, the Registrant will indemnify its current and former executives, any person who is serving or has served at the request of the Registrant as a director, executive or trustee of another company, joint venture, trust or other enterprise, and its directors and secretaries to the fullest extent permitted by law, against liabilities that are incurred by such executives, trustees, directors and secretaries while executing the duties of their respective offices. However, under the articles of association of the Registrant, unless the adjudicating court determines otherwise, such executives, trustees, directors and secretaries will not be entitled to indemnification by the Registrant if they are adjudged to be liable for fraud or dishonesty in the performance of their duties to the Registrant.

The current and certain former directors, secretaries and executive officers of the Registrant, and certain directors and officers of certain of the Registrant’s subsidiaries, including Alkermes, Inc., are entitled to be indemnified pursuant to indemnification agreements with the Registrant and/or Alkermes, Inc. Under the terms of these indemnification agreements, and subject to any conditions to indemnity set forth therein, (i) the Registrant and/or Alkermes, Inc., as applicable, indemnifies each relevant director, secretary, or officer to the maximum extent permitted by law for expenses and other amounts actually and reasonably incurred by or on behalf of the director, secretary, or officer in relation to claims brought against such director, secretary, or officer that arise from actions taken while acting as a director, secretary, or officer of the Registrant and/or its subsidiaries, except to the extent that such indemnification is prohibited by applicable law or would be duplicative of amounts otherwise actually provided to such director, secretary, or officer in relation to such claims; (ii) the Registrant and/or Alkermes, Inc. will, to the maximum extent permitted by law, advance the expenses of such director, secretary, or officer in connection with his or her defense and (iii) each director, secretary, or officer undertakes, to the fullest extent required by law, to repay all amounts advanced if and to the extent it is ultimately determined by a court of competent jurisdiction in a final judgment that he or she is not entitled to be indemnified by the Registrant and/or Alkermes, Inc., as applicable.

The Registrant has also obtained directors’ and officers’ liability insurance which insures its executives and directors against certain liabilities that such persons may incur in their capacities as officers and/or directors of the Registrant.

Item 7. Exemption from Registration Claimed.

Not applicable.

Item 9. Undertakings.

(a) The undersigned Registrant hereby undertakes:

(1) to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i) and (a)(l)(ii) do not apply if the registration statement is on Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement.

(2) that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
