RUBIX HOLDINGS LIMITED
RUBIX HOLDINGS LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 00353430, and its current status with Companies House is active. The company was incorporated on 30 May 1939 and lists its registered address as London, United Kingdom. 1 shareholder is on record for RUBIX HOLDINGS 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 House and was last updated on 28 October 2026.

One shareholder is currently on record for RUBIX HOLDINGS LIMITED, held on the Confirmation Statement (CS01), filed under the Companies Act 2006.

Officers
5
Two of the 5 officer records shown for RUBIX HOLDINGS LIMITED are current appointments, filed with Companies House. Paul Finnigan (appointed 2018-05-16) and Katherine Phillips (appointed 2023-10-01) both serve as Director. The remaining 3 records shown (Duncan Magrath, Andrew Silverbeck and 1 other) are former appointments that have since been resigned.
The register reports 25 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at RUBIX HOLDINGS 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
RUBIX HOLDINGS LIMITED sits 10 levels below its ultimate parent, Advent International, L.P., registered in United States. 1 subsidiary is recorded beneath it, across 1 jurisdiction. Immediately above RUBIX HOLDINGS LIMITED is RUBIX GROUP MIDCO 4 LIMITED, holding 100% as filed in RUBIX HOLDINGS LIMITED's own shareholder record with Companies House. Advent International, L.P. 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 1 subsidiary spans United Kingdom 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.
