TGS ASA is a Public Limited Company registered in Norway under 976695372, with active status. The company was incorporated on 21 August 1996 and lists its registered address as OSLO, Norway. 5 shareholders are on record for TGS ASA, 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.

Shareholders

5

The largest of these is T. ROWE PRICE Intl Fd.S, INC.-T. Rowe Price Intl Discovery Fd., holding 21.8% — the largest recorded stake — followed by American Century ETF Trust-Avantis International Small Cap Value ETF at 18.1%; the remaining 3 shareholders shown hold smaller stakes.

The register reports 14 shareholders in total, though only the top 5 by holding are shown in this view.

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.

The register reports 46 officers in total, including past appointments, though only the 5 most relevant records are shown here.

Group Structure

TGS ASA has no recorded parent company — it sits at the top of its own group structure, with 11 subsidiaries recorded beneath it across 5 jurisdictions. 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 11 subsidiaries span Norway, United Kingdom, Indonesia, Nigeria, Australia 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. Seven of the 11 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
