Ketchum Steven B 4

What happened

• Steven B. Ketchum, EVP and Chief Scientific Officer of Amarin (AMRN), had restricted stock units (RSUs) vest on Jan 31, 2026 that converted into 4,179 ADS. To cover the tax liability, Amarin withheld 2,297 ADS at $15.42 each, representing $35,420 (this withholding is not a market sale). Net new ADS added to his holdings from the vesting were 1,882 ADS.
• On Feb 1, 2026 Ketchum received additional equity awards: 8,013 new RSUs and an option covering 36,060 ADS. These awards are subject to multi-year vesting schedules (see Key Details).

Key details

• Transaction dates: vesting/conversion and tax withholding: Jan 31, 2026; new grants: Feb 1, 2026. Form 4 filed Feb 3, 2026 (reporting period 2026-01-31).
• Tax withholding price: $15.42 per ADS; amounts withheld: 1,235 ADS ($19,044) and 1,062 ADS ($16,376), total $35,420.
• Shares from vesting: 2,246 ADS (from 2023 RSU grant) + 1,933 ADS (from 2024 RSU grant) = 4,179 ADS vested; 2,297 ADS withheld; net +1,882 ADS.
• New awards: 8,013 RSUs (granted 2/1/2026; vest in three equal annual installments on Jan 31 of 2027–2029) and an option for 36,060 ADS (granted 2/1/2026; vests 33% on first anniversary, then quarterly over the next two years).
• Notable footnotes: (F1) amounts reflect a prior ADS/ordinary-share ratio adjustment (1 ADS = 20 ordinary shares); (F4) shares “disposed” were withheld to satisfy tax withholding and were not open-market sales; (F6/F7/F8) RSU and option vesting terms/cash-in-lieu provisions apply.
• Shares owned after the transactions: not specified in the provided excerpt.

Context

• This was a routine RSU vesting event (not an open-market sale). Withholding to satisfy tax obligations is common and does not necessarily indicate a manager selling shares for investment reasons.
• The Feb 1 grants are forward-looking compensation that vest over multiple years; they represent potential future shares only if vesting conditions are met.
