GW PHARMACEUTICALS LIMITED
GW PHARMACEUTICALS LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 04160917, and its current status with Companies House is active. The company was incorporated on 15 February 2001 and lists its registered address as London, United Kingdom. 1 shareholder is on record for GW PHARMACEUTICALS 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 17 October 2026.

Three of the 5 officer records shown for GW PHARMACEUTICALS LIMITED are current appointments, filed with Companies House. David Spackman (appointed 2023-01-13) and Amanda Flanagan (appointed 2025-02-10) both serve as Director; Alkesh Patel (appointed 2024-04-03) serves as Company Secretary. The remaining 2 records shown (Nelly Armissoglio Ep. Lepelletier and Aislinn Doody) are former appointments that have since been resigned.
The register reports 33 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at GW PHARMACEUTICALS 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
GW PHARMACEUTICALS LIMITED sits 2 levels below its ultimate parent, JAZZ INVESTMENTS EUROPE LIMITED, registered in Malta. 2 subsidiaries are recorded beneath it, across 1 jurisdiction. Immediately above GW PHARMACEUTICALS LIMITED is JAZZ PHARMACEUTICALS UK HOLDINGS LIMITED, holding 100% as filed in GW PHARMACEUTICALS LIMITED's own shareholder record with Companies House. JAZZ INVESTMENTS EUROPE 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. One of the 2 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
