AMRN

Amarin Corporation plc (NASDAQ: AMRN) (“Amarin” or the “Company”) today issued the following statement in response to Sarissa’s latest misstatements regarding the Company’s management compensation:

The Amarin Board of Directors, consistent with standard public company practice and in line with its fiduciary responsibilities, authorized its management compensation plan for 2023. Contrary to Sarissa’s claims, the timing of the plan approval was in February, which is consistent with previous years. In addition, as part of this year’s compensation plan (like all prior years), all Amarin employees globally received annual performance grants. Sarissa’s comment that Karim Mikhail’s equity grants vest “solely based on the passage of time” is also another misrepresentation of the facts. Mr. Mikhail’s compensation package includes performance-based grants, which are only triggered if performance thresholds are achieved.

Sarissa also insinuates that the Board is “refusing” to release the results of the General Meeting – this is another misrepresentation of the facts. The General Meeting has not occurred yet, and Sarissa and its legal advisors both know that companies do not publicize preliminary results prior to any general meeting, consistent with SEC guidelines. The Board assures shareholders that the results of the General Meeting will be posted in a timely manner following the conclusion of the meeting.
