CGG SERVICES SAS
CGG Services SAS is a French société par actions simplifiée (SAS) registered in France under SIREN 403 256 944 (SIRET 403 256 944 00063), with its registered office at 27 Avenue Carnot, 91300 Massy. The company was incorporated on 26 December 1995 and entered in the Registre du Commerce et des Sociétés on 4 January 1996. Its current registry status is active. This corrects the legal form recorded elsewhere as “Public Limited Company”: French commercial-registry filings identify CGG Services SAS as a simplified joint-stock company (SAS), not a publicly listed entity in its own right.
The company is classified under NAF/APE code 71.12B, engineering and technical studies. Its registered corporate purpose covers the identification, evaluation, understanding and resolution of issues relating to natural resources, the environment and Earth infrastructure, consistent with its role as an operating entity in geoscience and Earth-data services. CGG Services SAS holds fixed share capital of €100,000,000 and was reported in registry filings as employing between 250 and 499 people in 2023, placing it in the mid-sized enterprise (ETI) category under French classification.
For the financial year ended 31 December 2024, filed company-level accounts reported CGG Services SAS turnover of €125,609,000 and a net loss of €41,825,000. On 3 December 2025, CGG Services SAS completed a simplified merger absorbing Geomar (SIREN 413 926 320), a related entity registered at the same Massy address, with retroactive effect from 30 September 2025.

Shareholders
5
French commercial-registry filings show CGG Services SAS as a simplified joint-stock company with a single shareholder (société par actions simplifiée à associé unique). Registry records identify Compagnie Générale de Géophysique — trading since May 2024 as Viridien SA (Euronext Paris: VIRI, SIREN 969 202 241) — as the company’s sole registered shareholder, holding the entire issued share capital. This single-shareholder structure was confirmed in the entity’s most recent registry extract, retrieved 21 August 2026.
Ultimate beneficial ownership
No natural-person ultimate beneficial owner is identified for CGG Services SAS in the registry extracts reviewed. Because its sole shareholder, Viridien SA, is itself listed on Euronext Paris with a dispersed institutional and retail shareholder base, no single individual or entity can be verified as holding a calculable effective ownership percentage through the chain. France’s central beneficial-ownership register (registre des bénéficiaires effectifs) is not publicly searchable in full, and no such filing for this entity was located through the sources reviewed.
Data availability
Direct shareholder information is classified as Full: the identity of the sole shareholder is disclosed in the French commercial registry. Beneficial-ownership information beyond the immediate corporate shareholder is classified as Not public, reflecting restrictions on access to France’s beneficial-ownership register rather than an absence of beneficial owners.

Group Structure
CGG Services SAS operates as a wholly owned operating subsidiary within the Viridien group. French commercial-registry filings confirm its immediate and sole parent as Compagnie Générale de Géophysique, trading since May 2024 as Viridien SA (Euronext Paris: VIRI; SIREN 969 202 241), a geoscience, digital and Earth-data group headquartered at the same address, 27 Avenue Carnot, 91300 Massy. Viridien SA was named CGG SA until shareholders approved the rebrand at the Annual General Meeting on 15 May 2024. No entity beyond Viridien SA was identified as an ultimate parent, since Viridien SA is itself publicly listed with a dispersed shareholder base rather than being controlled by a further verified parent.
