What Sofresid Engineering does

Sofresid Engineering, operating under the EKIUM brand, is a French-based international engineering services group and a wholly-owned subsidiary of Groupe SNEF. The firm provides end-to-end engineering services across naval, energy, life sciences, and general industrial sectors, with stated operations in 18 countries and a workforce of approximately 2,700 engineers, experts, and technicians. Its service portfolio spans four core pillars — Consulting & Permitting, Ingénierie & Maîtrise d'œuvre (engineering and project management), Expertises Techniques (specialized technical expertise), and Automation & IT — supplemented by Energy Performance & Decarbonation, Innovation, and CSR engagements. Business is conducted primarily through professional services engagements covering the full project lifecycle from feasibility through maintenance, with managed services revenue from facility infogérance contracts such as the 7-year LMJ facility partnership with CEA.

The customer base is dominated by large European industrial and government enterprises, including Airbus, Naval Group, Navantia, EDF, ENGIE, TotalEnergies, Orano, CEA, Sanofi, Novartis, AstraZeneca, ArcelorMittal, Arkema, Solvay, INEOS, and Lyondellbasell, indicating a project-driven B2B enterprise field sales motion. The firm pursues an active expansion strategy, having acquired Scitech (Life Sciences) in 2024 and Pureworld Engineering (international development) in 2025, while taking an equity stake in Canadian engineering firm Norda Stelo and forming a strategic partnership with Otrera for next-generation nuclear reactor development. It operates within a parent ecosystem (Groupe SNEF) that includes complementary brands such as Watt, Fouré Lagadec, iQanto, Abgi, and Visiativ, and has renewed its EcoVadis Silver Medal for ESG performance.
