HORIZON THERAPEUTICS IRELAND DESIGNATED ACTIVITY COMPANY
HORIZON THERAPEUTICS IRELAND DESIGNATED ACTIVITY COMPANY is a registered legal entity registered in Ireland under IE376554, and its current status with Companies Registration Office (CRO) is active. The company was incorporated on 3 October 2003 and lists its registered address as Ireland. 1 shareholder is on record for HORIZON THERAPEUTICS IRELAND DESIGNATED ACTIVITY COMPANY, 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 20 October 2026.

Shareholders

Group Structure
HORIZON THERAPEUTICS IRELAND DESIGNATED ACTIVITY COMPANY sits 5 levels below its ultimate parent, Amgen Inc., registered in United States. 1 subsidiary is recorded beneath it, across 2 jurisdictions. The full chain up to Amgen Inc. is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by HORIZON THERAPEUTICS IRELAND DESIGNATED ACTIVITY COMPANY's own shareholder record. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 1 subsidiary spans Ireland, Switzerland 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.
