MICROSOFT IRELAND RESEARCH UNLIMITED COMPANY
MICROSOFT IRELAND RESEARCH UNLIMITED COMPANY is a Private limited company (Ltd.) registered in Ireland under IE342235, and its current status with Companies Registration Office (CRO) is active. The company was incorporated on 25 April 2001 and lists its registered address as Ireland. 2 shareholders are on record for MICROSOFT IRELAND RESEARCH UNLIMITED 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.

Shareholders
2
Two shareholders are currently on record for MICROSOFT IRELAND RESEARCH UNLIMITED COMPANY, 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 MICROSOFT ROUND ISLAND ONE UNLIMITED COMPANY, holding 100% — a majority holding — followed by MICROSOFT ROUND ISLAND ONE UNLIMITED COMPANY at 0%.
Because every 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.

The register reports 25 officers in total, including past appointments, though only the 5 most relevant records are shown here.

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
MICROSOFT IRELAND RESEARCH UNLIMITED COMPANY sits 4 levels below its ultimate parent, Microsoft Corporation, registered in United States. 25 subsidiaries are recorded beneath it, across 17 jurisdictions. Immediately above MICROSOFT IRELAND RESEARCH UNLIMITED COMPANY is MICROSOFT ROUND ISLAND ONE UNLIMITED COMPANY, holding 100% as filed in MICROSOFT IRELAND RESEARCH UNLIMITED COMPANY's own shareholder record with Companies Registration Office (CRO). Microsoft Corporation sits further up the chain, a link derived by walking shareholder filings across jurisdictions rather than stated in a single document. 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 25 subsidiaries span Ireland, Sweden, Denmark, Germany, United Kingdom, New Zealand, and 11 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. Seven of the 25 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
