What Gestal does

Gestal is a French industrial services group founded in 1946 and headquartered in Saint-André-des-Eaux, near Saint-Nazaire, with approximately 800 employees and €120M+ in turnover distributed across 15 sites in France and internationally (Romania, Canada, Germany). The company operates as a multi-vertical industrial platform serving prime contractors in naval and defense (Naval Group, Chantiers de l'Atlantique), aerospace (Airbus, Bombardier), energy — both renewable and nuclear (GE Renewable Energy, EDF, RTE, Engie, SPIE, Man Energy Solutions), construction (Vinci, Bouygues Construction), pharmaceutical and chemical (Pierre Fabre, Boehringer Ingelheim), and general manufacturing (Michelin, Siemens). Its service offering spans the full industrial lifecycle: design, manufacturing, installation, commissioning, and maintenance, with capabilities in electromechanics, mechanics, piping, boiler-making, welding, electrical systems, and specialized metalwork.

Revenue is generated primarily through long-term maintenance contracts (15,000 to 100,000 hours per year) complemented by project-based new construction (Travaux Neufs), production services (metalwork, welding, assembly), and professional training delivered via the in-house CFN training center. Go-to-market is exclusively direct B2B enterprise sales, with no digital marketplace or reseller channel. Pricing is project- and contract-specific, with structures ranging from fixed-price contracts with bonus clauses to unit-rate contracts spanning short durations to several decades. The company holds sector-critical certifications — EDF UTO CAS 1 for nuclear, GMP/BPF for pharmaceutical, MASE for safety, and CODETI for pressure equipment — that function as hard barriers to entry in regulated work.

Following its 2018 acquisition by FCDE, Gestal has executed an aggressive buy-and-build strategy, integrating Roma2s (Romania, 2019), RCTI and TIS (2022), SETCA (2023), and SMS (2025), while launching AGWIND for renewable energy (2022) and opening a Canadian branch (2023). In 2024, BNP Paribas Développement, Bpifrance, and Sodero joined FCDE as shareholders, reinforcing the capital base for continued external growth under CEO Olivier Aldrin.
