JANUS HENDERSON ADMINISTRATION UK LIMITED
JANUS HENDERSON ADMINISTRATION UK LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 00290577, and its current status with Companies House is active. The company was incorporated on 26 July 1934 and lists its registered address as London, United Kingdom. 1 shareholder is on record for JANUS HENDERSON ADMINISTRATION UK 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.

Group Structure
JANUS HENDERSON ADMINISTRATION UK LIMITED sits 2 levels below its ultimate parent, JANUS HENDERSON GROUP PLC, registered in United Kingdom. 1 subsidiary is recorded beneath it, across 1 jurisdiction. Immediately above JANUS HENDERSON ADMINISTRATION UK LIMITED is JANUS HENDERSON UK (HOLDINGS) LIMITED, holding 100% as filed in JANUS HENDERSON ADMINISTRATION UK LIMITED's own shareholder record with Companies House. JANUS HENDERSON GROUP 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 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.
