GARTMORE INVESTMENT MANAGEMENT LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 00953703, and its current status with Companies House is active. The company was incorporated on 7 May 1969 and lists its registered address as London, United Kingdom. 3 shareholders are on record for GARTMORE INVESTMENT MANAGEMENT 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 8 October 2026.

Shareholders

3

Three shareholders are currently on record for GARTMORE INVESTMENT MANAGEMENT LIMITED, held on the Confirmation Statement (CS01), filed under the Companies Act 2006.

The largest of these is HENDERSON GLOBAL INVESTORS ASSET MANAGEMENT LIMITED, holding 90.9% — a majority holding — followed by HENDERSON GLOBAL INVESTORS ASSET MANAGEMENT LIMITED at 90.9%; the remaining 1 shareholder shown holds smaller stakes.

Because every 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.
