Fishman Peter L. 4

What Happened
Peter L. Fishman, SVP and CFO of Amarin Corporation plc (AMRN), had RSUs vest on April 1, 2026. The filing shows two derivative/conversion entries for 125 shares each (RSU conversion/derivative exercise) with an exercise price of $0.00 for one entry, and the issuer withheld 62 shares to cover tax withholding valued at $14.46 per share (total ~$897). This was not an open-market sale — the 62-share disposition reflects issuer withholding for taxes.

Key Details

• Transaction date: April 1, 2026; Form 4 filed April 2, 2026 (timely).
• Acquired: 125 shares via derivative exercise/RSU vesting (reported $0.00 exercise price).
• Withheld (Disposed): 62 shares to cover tax liability at $14.46/share, total ~$897 (withholding, not a sale).
• Shares owned after transaction: not specified in this Form 4.
• Relevant footnotes: RSUs were granted April 1, 2023 and vested in three installments (125 each on 4/1/24, 4/1/25, 4/1/26); each RSU represents a right to receive twenty Ordinary Shares or cash in lieu per issuer terms; reporting reflects a prior ADS/ordinary-share ratio change and withholding is issuer tax withholding (not a market sale).

Context: These entries reflect routine RSU vesting and tax-withholding rather than a discretionary open-market sale or purchase. For RSU vesting, an exercise price of $0.00 is typical (the award converts to shares), and withholding by the issuer to satisfy tax obligations is common and does not necessarily indicate insider buying or selling sentiment.
