GREENCASTLE ACQUISITION LIMITED
GREENCASTLE ACQUISITION LIMITED is a Private limited company (Ltd.) registered in Ireland under IE673639, and its current status with Companies Registration Office (CRO) is active. The company was incorporated on 9 July 2020 and lists its registered address as Dublin Docklands, Ireland. 1 shareholder is on record for GREENCASTLE ACQUISITION 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 26 October 2026.

Shareholders
1
One shareholder is currently on record for GREENCASTLE ACQUISITION 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 LINTON CAPITAL LLP, 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
2
Two officers are currently on record for GREENCASTLE ACQUISITION LIMITED, filed with Companies Registration Office (CRO). JOHN MICHAEL O'CONNOR (appointed 2021-03-30) and IQ EQ CORPORATE SECRETARIES (IRELAND) LIMITED (appointed 2021-03-30) both serve as Company Secretary.
Management authority at GREENCASTLE ACQUISITION 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
GREENCASTLE ACQUISITION LIMITED has no recorded parent company — it sits at the top of its own group structure, with 1 subsidiary recorded beneath it across 1 jurisdiction. 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 jurisdiction, 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 1 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
