Ketchum Steven B 4

What Happened

• Steven B. Ketchum, Executive Vice President and Chief Scientific Officer of Amarin Corporation plc (AMRN), had restricted stock units (RSUs) vest on July 1, 2026. The filing shows 3,688 shares acquired via award/conversion (codes A and M) and 1,887 shares withheld to cover tax liability (code F) at $15.94 per share, totaling $30,079 withheld. This was a vesting/award event rather than an open-market purchase or intentional sale.

Key Details

• Transaction date: July 1, 2026; Form 4 filed July 15, 2026 (filed 14 days after the transaction; Form 4s are normally due within 2 business days).
• Shares acquired: 3,688 (award/conversion; codes A and M).
• Shares withheld for taxes: 1,887 at $15.94 each; cash value withheld = $30,079 (code F).
• Post-transaction holdings: Not specified in the filing.
• Footnotes of note:
  • ADS ratio change (F1): effective April 11, 2025 one ADS = 20 ordinary shares; reported amounts reflect that ratio adjustment.
  • Original grant (F2): 7,376 RSUs granted Jan 10, 2025; scheduled to vest 50% Jan 2, 2026 and remaining 50% on July 1, 2026.
  • Withholding (F4): the 1,887-share disposition represents issuer withholding to satisfy tax liability (not an open-market sale).
  • Each RSU represents a contingent right to receive 20 ordinary shares or cash in lieu (F5).
• Transaction codes: M = exercise/conversion of derivative; A = award/grant; F = tax withholding.

Context

• This was a routine RSU vesting with a cashless-type settlement for taxes (shares withheld by the issuer), not a market sale. Such withholding is standard and does not necessarily signal insider sentiment for buying or selling shares. The delayed filing (filed Jul 15 for a Jul 1 transaction) appears late relative to typical Form 4 timing and may be worth noting for timing compliance.
