What believers are saying

  • H1 2026 revenue grew 2.5% organically; nuclear grew 8.0%.
  • France delivered 4.2% organic growth on new-builds, fuel cycle, and digitalisation.
  • UK momentum accelerated after April 2026 SMR, CPS2, and MoD framework wins.

What critics are saying

  • Nuclear concentration leaves Assystem exposed if French EPR2 schedules slip beyond 2027.
  • H1 2026 international revenue fell from currency hits and project endings in India.
  • Rolls-Royce SMR still needs FID, regulatory clearance, and site decisions before revenue scales.

What makes ASSYSTEM unique

  • Assystem derived 81% of H1 2026 revenue from nuclear engineering.
  • April 2026 UK wins placed Assystem on CPS2 and MoD delivery frameworks.

Assystem's H1 revenue rises 2.5% organically to $371.2M on nuclear growth

Assystem reported consolidated revenue of €328.5 million for the first half of 2026, representing organic growth of 2.5% despite a 1.9% negative currency effect. The French engineering group's nuclear activities drove performance with 8.0% organic growth, accounting for 81% of total revenue. Revenue in France rose 4.2% organically to €201.1 million, led by strong momentum in nuclear new-builds and fuel cycle activities. International operations generated €127.4 million, remaining stable organically despite currency headwinds from the pound sterling, Indian rupee, and Saudi riyal. The UK showed robust growth in civil nuclear engineering and defence. However, business volumes declined in the Middle East, Central Asia region and India due to project endings and slower contract phasing. Assystem confirmed its full-year 2026 targets.

Assystem posts $187.4M Q1 revenue with 2.2% organic growth driven by nuclear sector

Assystem, an international engineering group, reported first-quarter 2026 consolidated revenue of €165.8 million, representing 2.2% organic growth driven by strong nuclear sector performance of 8.0%. Nuclear activities accounted for 81% of total revenue, up from 76% in the prior year. French operations grew 4.4% to €102.6 million, driven by momentum in fuel cycle activities, new-builds and digitalisation. International revenue declined 7.1% to €63.2 million, primarily due to a 6.0% negative currency effect from the pound sterling, Indian rupee and Saudi riyal. The UK showed robust growth in civil nuclear engineering and defence. Assystem secured key positions on government frameworks and its client Rolls-Royce SMR signed a contract with Great British Energy for three small modular reactors.
