AMARIN CORPORATION PLC
AMARIN CORPORATION PLC is a registered legal entity registered in Ireland under IE905980, and its current status with Companies Registration Office (CRO) is active. The company was incorporated on 1 March 1989 and lists its registered address as Ireland. 2 shareholders are on record for AMARIN CORPORATION PLC, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Companies Registration Office (CRO) and was last updated on 18 September 2026.

Data availability
Those 2 subsidiaries span Ireland, United States jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. One of the 2 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
