BIOATLANTIS LIMITED
BIOATLANTIS LIMITED is a Private limited company (Ltd.) registered in Ireland under IE377737, and its current status with Companies Registration Office (CRO) is active. The company was incorporated on 5 November 2003 and lists its registered address as Ireland. 1 shareholder is on record for BIOATLANTIS 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 23 October 2026.

Shareholders
1
One shareholder is currently on record for BIOATLANTIS LIMITED, held on the Annual Return (Form B1) under section 342 of the Companies Act 2014, which the register supplies only on payment.
The largest of these is BIOATLANTIS HOLDINGS LIMITED, holding 100% — a majority holding.
Because the shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Officers
5
The Director of BIOATLANTIS LIMITED currently on record is JOHN O'SULLIVAN; five officers are currently on record for BIOATLANTIS LIMITED, filed with Companies Registration Office (CRO).
The register reports 11 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at BIOATLANTIS LIMITED sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
BIOATLANTIS LIMITED sits 1 level below its ultimate parent, BIOATLANTIS HOLDINGS LIMITED, registered in Ireland. 2 subsidiaries are recorded beneath it, across 2 jurisdictions. The full chain up to BIOATLANTIS HOLDINGS LIMITED is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by BIOATLANTIS LIMITED'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 2 subsidiaries span Ireland, China 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.
