Paul Cohen, a director of Amarin Corporation plc (AMRN), had 838 shares acquired on April 18, 2026 through the exercise/conversion of a derivative (RSUs). Of those, 403 shares were withheld by the issuer to satisfy tax withholding obligations at $14.98 per share, totaling $6,037.

Key Details

• Transaction date: April 18, 2026. Filing date: April 21, 2026.
• Acquired: 838 shares via exercise/conversion of a derivative (reported as code M).
• Tax withholding: 403 shares withheld (code F) at $14.98 per share = $6,037; withholding is issuer-retained shares, not an open-market sale (footnote F4).
• Price shown for the derivative conversion: $0.00 (no cash exercise price for the vested RSUs).
• Footnotes: F1 notes a prior ADS ratio change (1 ADS = 20 ordinary shares) and that reported amounts reflect that change; F2 explains the RSU grant and vesting schedule (granted 4/18/2024, vesting in three installments on 4/18/2025, 4/18/2026, 4/18/2027); F5 clarifies each RSU represents a contingent right to 20 ordinary shares or cash.
• Shares owned after the transaction: not disclosed in the provided excerpt.

Context
This was a routine vesting/conversion of equity awards (RSUs) with shares withheld to cover taxes — not an open‑market sale. For retail investors, such withholding is administrative and does not necessarily indicate directional insider sentiment. The filing shows conversion/exercise of derivative awards rather than a cash purchase.
