DIONE HOLDCO LIMITED
DIONE HOLDCO LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 13620220, and its current status with Companies House is active. The company was incorporated on 14 September 2021 and lists its registered address as London, United Kingdom. 1 shareholder is on record for DIONE HOLDCO 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 16 October 2026.

The register reports 8 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
DIONE HOLDCO LIMITED sits 1 level below its ultimate parent, DIONE TOPCO LTD, registered in United Kingdom. 1 subsidiary is recorded beneath it, across 1 jurisdiction. Immediately above DIONE HOLDCO LIMITED is DIONE TOPCO LTD, holding 100% as filed in DIONE HOLDCO LIMITED's own shareholder record with Companies House. 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. 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.
