Fishman Peter L. 4

What Happened

Peter L. Fishman, SVP & Chief Financial Officer of Amarin Corporation plc (AMRN), had previously granted RSUs vest on January 31, 2026 and the vesting resulted in the conversion/exercise of derivative awards into 563 and 1,833 shares (total 2,396). To cover tax liabilities on those vested awards, the company withheld 310 and 1,008 shares (total 1,318) for cashless tax withholding, resulting in cash/consideration reported of $4,780 and $15,543 respectively (total $20,323). On February 1, 2026 Fishman was also granted 6,167 new RSUs and an option to purchase 27,750 ADSs (American Depositary Shares) under the company plan; these new awards vest over multi‑year schedules.

Context

• The withholding of 1,318 shares was a standard cashless tax withholding related to RSU vesting (transaction code F) and should not be interpreted as an opportunistic sale of shares on the open market.
• The conversions listed as “M” reflect exercise/conversion of derivative awards (RSUs/options becoming deliverable ADSs), and the new grants (RSUs and option grant) are standard compensation awards with multi‑year vesting schedules.
