About ASSYSTEM

Assystem is a French engineering and project-management group focused on highly regulated industries, with nuclear energy at the core of its identity and strategy. Founded more than 60 years ago, the company has developed a long-standing reputation for supporting complex industrial and infrastructure projects across their full life cycle, from concept and design through construction, operations support, life-extension and decommissioning. Historically rooted in the nuclear sector, Assystem now ranks among the world’s leading nuclear engineering firms and was ranked 2nd worldwide in the ENR 2025 “Nuclear Plants” category. The group presents itself as an active contributor to the global energy transition, leveraging engineering expertise, digital solutions and program management to improve the safety, efficiency and sustainability of critical assets. Assystem’s business model is built around three main pillars: engineering services, digital services and project management. In practice, this means supporting clients with technical studies, safety engineering, owner’s engineering, construction assistance, maintenance optimization, reactor life extension, fuel-cycle-related services, waste management and dismantling. Beyond nuclear, the group also works on selected energy and infrastructure projects, which broadens its technical base while keeping its strategic focus on complex, regulated environments. Assystem states that it operates in 13 countries and employs around 8,000 “Switchers,” reflecting a sizeable international footprint and a highly skilled workforce. This global reach enables the company to serve major industrial and public-sector customers across Europe, the Middle East, Asia and North America. A key differentiator is Assystem’s strong safety culture, which is central to nuclear risk management and the company’s credibility with operators and public authorities. The group is also benefiting from renewed interest in nuclear power in multiple geographies, as governments look for low-carbon, dispatchable and sovereign energy solutions. From an investment perspective, Assystem stands out as a niche engineering services company with high technical barriers to entry, deep sector expertise and significant exposure to long-duration nuclear and energy-transition programmes.
