H. A. O’NEIL LIMITED
H. A. O’NEIL LIMITED is a Private limited company (Ltd.) registered in Ireland under IE010341, and its current status with Companies Registration Office (CRO) is active. The company was incorporated on 28 May 1942 and lists its registered address as DUBLIN 2 D04 HN50 IRELAND, Ireland. 1 shareholder is on record for H. A. O’NEIL LIMITED, 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 29 September 2026.

Those 6 subsidiaries span Ireland, Norway, Finland, Netherlands, Spain, United Kingdom, and 1 more 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.
