Amarin (NASDAQ: AMRN) cuts board seats and revises director equity pay

Rhea-AI Filing Summary

Amarin Corporation plc is reshaping its governance structure and updating how it pays non-employee directors. As part of an effort to follow what it views as best corporate governance practices, the board decided to reduce its size. On March 25, 2026, directors Paul Cohen and Oliver O’Connor chose not to stand for re-election at the 2026 annual meeting and will resign immediately before that meeting begins; their decisions are stated to be unrelated to any disagreement over operations, policies, or practices. The board will cut its size from nine to seven directors at that time.

The board also approved a revised non-employee director compensation policy. Each non-employee director is eligible for initial and annual equity awards of restricted stock units and options that vest in full on the earlier of one year after the grant date or the next annual meeting. These equity awards depend on shareholders approving both an issuance proposal and a pre-emption proposal at the 2026 annual meeting; if either fails, directors will not receive these equity awards and the board will consider alternative compensation such as cash.

Director Resignations

As part of its ongoing consideration of best corporate governance practices, the Board of Directors (the “Board”) of Amarin Corporation plc (the “Company”) has concluded that it would be in the best interests of the Company and its shareholders to reduce the size of the Board at this time. To that end, on March 25, 2026, Dr. Paul Cohen and Mr. Oliver O’Connor (the “Non-Continuing Directors”) each notified the Company that they had made the decision not to stand for re-election at the 2026 Annual Meeting of Shareholders. As a result, the Non-Continuing Directors will resign from the Board effective as of the time immediately before the commencement of the 2026 Annual Meeting of Shareholders (the “Effective Time”). Each of the Non-Continuing Directors’ decisions not to stand for re-election is not the result of any disagreement with the Company on any matter relating to the Company’s operations, policies or practices.

Also on March 25, 2026, the Board determined to reduce the size of the Board from nine to seven directors effective as of the Effective Time.

Director Compensation Policy

On March 25, 2026, the Board approved the following changes to the Company’s non-employee director compensation policy (as so updated, the “Director Compensation Policy”): each non-employee director of the Company is eligible to receive an annual equity award of Restricted Stock Units and Options (each as defined in the Company’s 2020 Stock Incentive Plan, as amended) which shall vest in full upon the earlier of the one-year anniversary of the grant date (which will be the date of the Company’s annual general meeting of shareholders) or the annual general meeting of shareholders in such anniversary year.

Pursuant to the Director Compensation Policy, each non-employee director on the Board receives an initial equity award upon appointment to the Board and an annual equity award upon initial appointment to the Board and for so long as such director remains on the Board; however, if shareholders do not approve both the issuance proposal and the pre-emption proposal to be voted on by shareholders of the Company at the 2026 Annual Meeting of Shareholders, the non-employee directors will not be able to receive their initial equity awards or annual equity awards and the Board will have to consider alternative forms of compensation, such as cash compensation.

The foregoing description does not purport to be complete and is qualified in its entirety by reference to the Director Compensation Policy. A copy of the Director Compensation Policy is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
