SIGMA PHARMACEUTICALS PLC
SIGMA PHARMACEUTICALS PLC is a Public Limited Company registered in United Kingdom under 01561802, and its current status with Companies House is active. The company was incorporated on 15 May 1981 and lists its registered address as London, United Kingdom. 1 shareholder is on record for SIGMA PHARMACEUTICALS PLC, 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 2 October 2026.

Shareholders
1
One shareholder is currently on record for SIGMA PHARMACEUTICALS PLC, held on the Confirmation Statement (CS01), filed under the Companies Act 2006.

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
5
The Director of SIGMA PHARMACEUTICALS PLC currently on record is Rajiv Shah; five officers are currently on record for SIGMA PHARMACEUTICALS PLC, filed with Companies House.
The register reports 17 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at SIGMA PHARMACEUTICALS PLC 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
SIGMA PHARMACEUTICALS PLC sits 2 levels below its ultimate parent, ORION (IOM) PLC, registered in United Kingdom. 3 subsidiaries are recorded beneath it, across 1 jurisdiction. Immediately above SIGMA PHARMACEUTICALS PLC is ORION HOLDINGS (UK) LIMITED, holding 100% as filed in SIGMA PHARMACEUTICALS PLC's own shareholder record with Companies House. ORION (IOM) PLC 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 3 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.
