Bonfiglio Patrice Eadon 4

What Happened

• Patrice Eadon Bonfiglio, a director of Amarin Corporation plc (AMRN), had 838 RSUs vest and was issued/converted 838 ADS-equivalent shares on April 18, 2026. The shares were issued at $0.00 (vesting conversion).
• To satisfy tax withholding, the issuer withheld 403 of those shares at $14.98 each, yielding $6,037. The withholding is reported as a disposition but is a tax withholding, not an open-market sale.

Key Details

• Transaction date: April 18, 2026; Form 4 filed April 22, 2026 (accession 0001193125-26-170731).

• Footnotes: F2 confirms the 2,514 RSU grant (April 18, 2024) vests in three equal installments (one installment = 838 RSUs vested Apr 18, 2026). F4 clarifies the 403-share action is issuer withholding for taxes, not a market sale. F5 and F1 explain ADS/ordinary-share conversion details (each RSU entitles the holder to 20 ordinary shares or cash; the report reflects an ADS ratio change effective Apr 11, 2025).

Context

• This was a vesting/conversion of RSUs (derivative-to-stock event). The director did not conduct an open-market sale — shares were withheld by the company to cover taxes (common administrative step). Such tax-withholdings are routine and do not necessarily signal intent to buy or sell additional shares.
