SIENNA MIDCO 2 LIMITED
SIENNA MIDCO 2 LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 15310672, and its current status with Companies House is active. The company was incorporated on 27 November 2023 and lists its registered address as Cardiff, United Kingdom. 1 shareholder is on record for SIENNA MIDCO 2 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 6 October 2026.

The register reports 10 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at SIENNA MIDCO 2 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
SIENNA MIDCO 2 LIMITED sits 2 levels below its ultimate parent, SIENNA TOPCO LIMITED, registered in United Kingdom. 2 subsidiaries are recorded beneath it, across 1 jurisdiction. Immediately above SIENNA MIDCO 2 LIMITED is SIENNA MIDCO 1 LIMITED, holding 100% as filed in SIENNA MIDCO 2 LIMITED's own shareholder record with Companies House. SIENNA TOPCO LIMITED 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 2 subsidiaries span 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. Two of the 2 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
