The Directors

Amarin Corporation plc

Block C

Grand Canal Docklands

Dublin 2, Ireland

January 10, 2023

Dear Sirs

Request to convene a general meeting of Amarin Corporation plc (“Company”) and special notice of a resolution to remove a director of the Company, if applicable

Pursuant to section 303 Companies Act 2006 (the “Companies Act”), the undersigned, being an authorized representative of the holders of not less than 5% of the paid-up share capital of the Company, as set forth on Appendix A attached hereto, which at the date of this requisition carries the right to vote at general meetings of the Company, requires you to call a general meeting of the Company not later than 21 days after you receive this requisition.

The business to be dealt with at the general meeting is to consider the proposals that (i) Patrice Bonfiglio, Paul Cohen, Mark DiPaolo, Keith L. Horn, Odysseas Kostas, Louis Sterling III, and Diane E. Sullivan each be appointed as a director of the Company, (ii) Per Wold-Olsen be removed from office as a director of the Company, and (iii) in the event any director is appointed after the Company’s receipt of this requisition, each such director be removed from office as a director of the Company.

At the general meeting it is intended to consider and, if thought fit, pass the following resolutions, which are being proposed as ordinary resolutions, and we give special notice pursuant to sections 168(2) and 312(1) of the Companies Act in relation to the resolutions to remove a director under section 168 of the Companies:

Ordinary resolution:

1.	“THAT Per Wold-Olsen be removed from office as a director of the Company with immediate effect.”
2.	“THAT in the event any director is appointed after the Company’s receipt of the general meeting requisition notice dated January 10, 2023, and prior to the general meeting, each such director be removed from office as a director of the Company with immediate effect.”
3.	“THAT each of Patrice Bonfiglio, Paul Cohen, Mark DiPaolo, Keith L. Horn, Odysseas Kostas, Louis Sterling III, and Diane E. Sullivan, having consented to act, be appointed as an additional director of the Company with immediate effect.”

The holders intend to solicit the holders of shares representing at least 67% of the voting power of shares entitled to vote on the election of directors in support of the foregoing director nominees.

Attached hereto as Appendix B are signed notices by each Director Nominee of their willingness to be elected as a director of the Company.

Signed by:

/s/ Mark DiPaolo

SARISSA CAPITAL SUBMITS NOTICE TO CALL A SPECIAL MEETING OF AMARIN SHAREHOLDERS TO

ADD DIRECTORS AND REMOVE CHAIRMAN PER WOLD-OLSEN

Sarissa believes current board lacks any remaining credibility for representing shareholders

Sarissa is astonished that Amarin board refuses to add shareholder representatives

Greenwich, CT, January 10, 2023 – Sarissa Capital Management LP (“Sarissa”) today made the following statement on Amarin Corporation plc (NASDAQ: AMRN):

At the last shareholder meeting, the shareholders, the owners of the company, loudly expressed their lack of faith in the board and management. Sarissa sought to place shareholder representatives on the board and engaged with the company in what turned out to be months of simply lip service by the board, led by its Chairman Per Wold-Olsen. Despite Sarissa having a track record of creating significant shareholder value in healthcare companies, including those with cardiovascular drugs such as The Medicines Company, Amarin’s board rejected adding any shareholder representatives to the board in favor of their own candidates, including today’s addition of a board candidate without any input from Sarissa, Amarin’s largest shareholder.

Amarin’s acknowledgement of its need for board refreshment is a positive step in recognizing the company’s many mishaps and the board’s own entrenchment. However, after months of back and forth, it is clear to us that this board refreshment process was a charade led by Chairman Per Wold-Olsen.

Sarissa is astounded by Amarin’s blatant disregard for shareholders. The board’s actions epitomize poor governance. We believe that they do not understand a board’s mission and duties to shareholders, the owners of the company. We can only conclude that Amarin’s board does not seek real change and instead wants to remain entrenched at the expense of shareholders.

Sarissa has submitted notice to Amarin under UK law to call a special meeting of shareholders to add 7 directors to the board and to remove Chairman Per Wold-Olsen from the board. In the event that the Amarin board attempts the contemptible act of continuing to entrench themselves by filling any of the vacancies on the board, takes any other actions in violation of their fiduciary duties or interferes with Sarissa’s exercise of its shareholder rights, Sarissa will initiate immediate legal action to hold all directors (including those added to the board) personally accountable to the fullest extent of the law. Such an act by the board would be the ultimate betrayal to shareholders. Sarissa will also seek to remove those directors appointed by the board in order to create the vacancies necessary to add Sarissa’s nominees to the board. We are asking all shareholders to remain engaged and voice their opinions by voting at the special meeting.
