Fishman Peter L. 4

What Happened

• Peter L. Fishman, SVP and CFO of Amarin Corporation plc (AMRN), had 2,447 restricted stock units (RSUs) vest on July 1, 2026. Those RSUs converted to 2,447 ADS-equivalent shares (derivative conversion). To cover tax withholding, 1,206 of those shares were surrendered at $15.94 per share for total withholding of $19,224. The transaction resulted in a net acquisition of 1,241 shares for Fishman.
• This was a vesting/award event (not an open-market sale). The withholding of shares to cover taxes is a routine administrative action, not a market sale.

Key Details

• Reported transactions: A (award/vesting) of 2,447 shares; M (conversion/exercise of derivative) of 2,447 shares; F (tax withholding) disposition of 1,206 shares at $15.94 each for $19,224.
• Net shares added from the vesting: 1,241 shares (2,447 vested − 1,206 withheld).

• Footnotes: The RSUs were part of a Jan 10, 2025 grant of 4,894 RSUs that vest in two tranches (50% on Jan 2, 2026 and 50% on Jul 1, 2026). Each RSU represents a contingent right to receive twenty Ordinary Shares (ADS ratio adjustments were applied; reported amounts reflect the ADS ratio change). The withheld shares represent tax withholding and are not a market sale.

Context

• This was a routine vesting and conversion of RSUs; the withholding of shares to cover taxes is common and should not be interpreted as a deliberate sale by the insider.
• For retail investors, awards/vestings signal compensation realization rather than a direct endorsement or rejection of the company’s outlook. The reported cash value of the withheld shares was about $19.2k.
