#### SARISSA CAPITAL UNCOVERS THAT AMARIN'S REGISTRAR HAD NOT BEEN INSTRUCTED TO ACCEPT BLUE PROXY CARDS EVEN THOUGH LEGALLY REQUIRED TO DO SO

#### Sarissa Assumes That Amarin Knew This Conduct Was Going On and Did Nothing To Stop It

#### Sarissa Acted to Correct the Issue, Ensuring That All Votes Submitted On The Blue Proxy Card Will Be Counted at the Amarin General Meeting

#### Amarin Shareholders That Already Voted on the Blue Proxy Card Do NOT Need to Take Any Action; Your Vote Will be Counted

Greenwich, CT, February 15, 2023 – Sarissa Capital Management LP ("Sarissa") today issued the following statement regarding Amarin Corporation plc (NASDAQ: AMRN):

Sarissa Capital, in voting its shares, uncovered that Amarin's registrar, the firm retained by Amarin to receive and process proxy cards, had not been instructed to accept blue proxy cards even though legally required to do so. Amarin's registrar believed it was only authorized to accept and process the white proxy cards. Sarissa assumes this conduct was condoned by, or worse, coordinated with Amarin. We believe this is another attempt by Amarin to entrench themselves and disenfranchise shareholders. Fortunately for shareholders, Sarissa acted to correct this problem and all votes that have been or will be submitted on the blue proxy card will be accepted.

**IF YOU ALREADY VOTED "FOR" ALL PROPOSALS AND SUBMITTED YOUR BLUE PROXY CARD, THERE IS NOTHING ELSE YOU NEED TO DO TO SUPPORT SARISSA'S NOMINEES. YOU DO NOT NEED TO VOTE AGAIN.**

Amarin is in dire need of change. Sarissa is Amarin's largest shareholder, owning more than 25 million shares. We are long term shareholders and have not sold any shares since acquiring our position. We have a stellar track record of success, including in the cardiovascular space, and we believe our nominees have the experience and qualifications to help unlock Amarin's true potential.

You can vote on the blue proxy card or the white proxy card, but if you want to fully support Sarissa, you must make sure that all "**FOR**" boxes are marked on your proxy card (blue or white) before you submit it.

If you have any questions on how to vote, we recommend that you contact Sarissa's proxy solicitor, D.F. King, by calling (800) 331-7024 or emailing <u>AMRN@dfking.com</u>.

We urge all shareholders to vote "**FOR**" the Sarissa Nominees and "**FOR**" the removal of Chairman Per Wold-Olsen on or prior to the deadline on Tuesday, February 21, 2023.
