CALLSIGN LTD.
CALLSIGN LTD. is a Private limited company (Ltd.) registered in United Kingdom under 07277719, and its current status with Companies House is active. The company was incorporated on 8 June 2010 and lists its registered address as London, United Kingdom. 1 shareholder is on record for CALLSIGN LTD., 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 23 October 2026.

Shareholders
1
One shareholder is currently on record for CALLSIGN LTD., held on the Confirmation Statement (CS01), filed under the Companies Act 2006.
The largest of these is CALLSIGN INC.., holding 100% — a majority holding.
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
Two of the 5 officer records shown for CALLSIGN LTD. are current appointments, filed with Companies House. Garth Ritchie (appointed 2022-03-31) and Zia Hayat (appointed 2023-08-31) both serve as Director. The remaining 3 records shown (Ian Welch, Corinne Thompson and 1 other) are former appointments that have since been resigned.
The register reports 8 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at CALLSIGN LTD. 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
CALLSIGN LTD. sits 1 level below its ultimate parent, Callsign, Inc., registered in United States. 1 subsidiary is recorded beneath it, across 2 jurisdictions. The full chain up to Callsign, Inc. is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by CALLSIGN LTD.'s own shareholder record. 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, United Arab Emirates jurisdictions, 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.
