What believers are saying

  • H1 2026 nuclear revenue grew 8.0% organically and reached 81% of total revenue.
  • French revenue rose 4.2% organically to €201.1 million, driven by nuclear new-builds.
  • UK civil nuclear engineering, defence, and government frameworks expand its addressable pipeline.

What critics are saying

  • Heavy nuclear concentration exposes Assystem to French or UK project delays and cancellations.
  • International volumes fell in India and the Middle East from project endings and slower phasing.
  • Currency weakness in sterling, rupee, and riyal continues to pressure reported growth.

What makes ASSYSTEM unique

  • Founded in 1966, Assystem specializes in nuclear engineering and project lifecycle services.
  • Its France business supports EDF across commissioning, new-builds, fuel cycle, and operations.
  • The 2025 Mactech Energy Group acquisition deepens its nuclear delivery capabilities.
