Amarin (AMRN) CFO Peter Fishman Exercises RSUs; Shares Withheld

What Happened
Peter L. Fishman, SVP and CFO of Amarin Corporation plc (AMRN), had 313 RSUs/ADS acquired/vested on August 1, 2026 (reported as an exercise/conversion and award). To cover withholding for taxes, 155 ADS were withheld/disposed at $14.26 each, producing a withholding value of $2,210. The 313 shares were reported with a $0 acquisition price because they were RSU vesting (awarded shares).

Key Details

• Transaction date(s): August 1, 2026 (Form 4 filed Aug 3, 2026 — appears timely within the 2-business-day rule).
• Reported entries: M (exercise/conversion) — 313 shares acquired; A (award/vesting) — 313 shares @ $0.00; F (tax withholding) — 155 shares disposed @ $14.26, totaling $2,210.
• Shares owned after transaction: not specified in the Form 4 filing.
• Footnotes of note:
  • F1: An ADS ratio change (effective Apr 11, 2025) was applied; reported amounts reflect that change.
  • F2/F5: These were RSUs originally granted Aug 8, 2022; each RSU represents a contingent right to receive twenty Ordinary Shares (or cash at the issuer’s discretion).
  • F4: The 155-share disposition is withholding to satisfy tax liability on vesting, not an open-market sale.

Context
This was a routine RSU vesting and related tax withholding, not a voluntary market sale or open-market purchase. For derivative/RSU transactions like this, withholding of shares to cover taxes is common and should not be treated as an insider expressing new market conviction.
