On January 26, 2023, Willkie Farr & Gallagher LLP sent an email to Ropes & Gray, claiming that Sarissa Capital Management LP disagreed that it was required but accepting the default approach Amarin Corporation plc had indicated would apply absent an alternative, valid proposal from Sarissa Capital. The Company also recommended its shareholders to vote against Sarissa Capital's nominees: Paul Cohen, Mark DiPaolo, Keith L Horn, Odysseas Kostas, Louis Sterling, Diane E Sullivan, and vote for its board nominee Per Wold-Olsen at the 2023 annual meeting of shareholders scheduled to be held on February 28, 2023.
