Berg Aaron 4

What Happened

• Aaron Berg, President and CEO of Amarin Corporation plc (AMRN), converted vested derivative awards into 4,179 ADSs (two conversions of 2,246 and 1,933 ADSs) on Jan 31, 2026 and had 2,298 ADSs withheld to cover tax withholding (1,235 and 1,063 ADSs) for a total withholding value of $35,435 ($19,044 + $16,391). These conversions show $0 exercise price (derivative conversion of RSUs).
• On Feb 1, 2026 Berg was granted 26,793 RSUs and an option to purchase 120,566 ADSs under the company’s 2020 Stock Incentive Plan; both awards vest over multi-year schedules (see details below).

• Transaction codes: M = exercise/conversion of derivative (RSU conversion), F = withholding to satisfy tax liability, A = grant/award.
• Shares acquired via conversion: 4,179 ADSs. Shares withheld for taxes (disposed): 2,298 ADSs; cash value withheld reported = $35,435.

• Filing timeliness: Form filed Feb 3, 2026 reporting Jan 31 transactions; no late filing indicated in the Form 4.

Context

• These were largely non‑market transactions tied to RSU vesting and routine tax withholding (not an open‑market sale). Conversions at $0.00 reflect vested RSUs/awards being settled into ADSs rather than a cash purchase.
• The new awards (RSUs and option) are standard long‑term compensation with multi-year vesting; they do not by themselves signal immediate buying or selling by the insider.
