Sarissa Continues to Mislead Shareholders by Distorting Facts and Promoting Misinformation

DUBLIN, Ireland and BRIDGEWATER., N.J., Feb. 09, 2023 (GLOBE NEWSWIRE) -- Amarin Corporation plc (NASDAQ: AMRN) (“Amarin” or the “Company”) today announced that it has mailed a letter to shareholders in connection with the General Meeting of Shareholders urging shareholders to vote “AGAINST” all proposals on the WHITE proxy card.

Time is short and the facts are clear. Act today to ensure that the Amarin Board and management team are best positioned to continue executing our transformation plan and deliver near- and long-term value for you.

1. We are a NEW Amarin: NEW Board, NEW Management Team and NEW Strategy.

The Amarin of today is a profoundly different company than 18 months ago. We recognized change was needed, and today, this new team is executing a turnaround strategy to drive value with the oversight of a purpose-built Board.

Amarin is making early progress. Now is the time for us to build on our momentum to turn the Company around and create value for our shareholders. It is not the time to remove our new, highly qualified Chairman, Per Wold-Olsen, nor is it the time to nearly double the size of the Board with underqualified candidates as part of Sarissa’s self-serving attempt to get on the Board.

2. Sarissa has a track record of value destruction.

Sarissa claims it has created value in the healthcare space, but the facts show the opposite:

The median total shareholder return (“TSR”) at companies during the tenure of Sarissa-nominated directors is NEGATIVE 24%.1

The companies that Sarissa excluded from its presentation have a median TSR of a staggering NEGATIVE 59%.1

In four instances, companies with Sarissa-nominated directors LOST OVER 75% of their value.1

3. Amarin has the right Board and team to maximize shareholder value. We don’t need Sarissa to do it.

When it comes to M&A, you should know that the Amarin Board is committed to evaluating any real opportunity that would maximize value for Amarin shareholders, including a sale of the Company. We specifically added M&A expertise to our Board – Adam Berger, who has extensive experience as a healthcare investment banker, including involvement in over 90 sales – as well as directors and a leadership team with extensive backgrounds at and relationships with large global pharma companies. Simply put, we don’t need Sarissa to maximize value.

Sarissa’s latest presentation recycles its own slides, fails to address serious misstatements Amarin has pointed out and has released even more misinformation to mislead shareholders, including:

Failing to address Sarissa’s abysmal record of destroying shareholder value.

Continuing to compare Amarin to The Medicines Company, an irrelevant example when it comes to M&A and implementing a subscription model.

Perpetuating misinformation regarding the Amarin Board’s comments on its refreshment process – alleged remarks that were never made.

Implying that four of Sarissa's seven candidates were involved in key financial and operational decisions at The Medicines Company. The ONLY Sarissa representative to serve on the Board of The Medicines Company was Alex Denner, and he is not included on Sarissa’s slate at Amarin.

Deliberately and knowingly misrepresenting established U.K. law regarding voting deadlines and voting deadlines set by Amarin’s ADS depositary. Amarin does not set these deadlines – U.K law and the depositary do.
