Explanation of Responses:

1. Each restricted stock unit ("RSU") represents a contingent right to receive one Ordinary Share or cash in lieu thereof at the Issuer's discretion.

2. On August 2, 2021, the Reporting Person was granted 143,300 RSUs under the Amarin Corporation plc 2020 Stock Incentive Plan. These RSUs vest in three equal installments on each of July 31, 2022, July 31, 2023 and July 31, 2024.

3. Not applicable.

4. The Ordinary Shares may be represented by American Depositary Shares, each of which currently represents one Ordinary Share.

Remarks:

The equity grant referenced above was supported by recommendations of the Company's independent compensation consultant and approved by the Remuneration Committee of the Company's Board of Directors. In the case of a Change of Control (as defined in the Issuer's stock incentive plan), the grants described in this Form 4 vest in full. As of the date of this Form 4, the Reporting Person owns or holds the right to acquire an aggregate of 1,411,417 Ordinary Shares of the Issuer in the form of Ordinary Shares, stock options and RSUs outstanding under the Issuer's stock incentive plans, including but not limited to certain performance-based RSUs that are earned only if certain pre-defined operational milestones are achieved and, in certain cases, then vest only if the recipient remains with the company for an extended period of time.
