Global Energy Transition and Nuclear Renaissance: Assystem's core business in nuclear engineering directly benefits from the increasing global focus on decarbonization and the expansion of nuclear energy for electricity production, driving demand for its specialized services.

Government Spending and Geopolitical Stability: A significant portion of Assystem's projects involves large-scale governmental or defense-related infrastructure. Geopolitical stability (or instability, influencing defense spending) and the budgetary decisions of governments directly impact the pipeline and funding of these critical projects.

Inflation and Interest Rate Environment: Rising inflation can increase operational and project costs for Assystem, potentially affecting profit margins on long-term contracts. Higher interest rates can also make financing for clients' large infrastructure projects more expensive, potentially delaying or reducing new investments.
