Amarin (AMRN) CFO Peter Fishman Receives RSUs; Withholds 1,206 Shares

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).
Shares owned after transaction: Not specified in the provided filing.
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.
