What believers are saying

  • H1 2026 revenue reached €328.5 million, with 2.5% organic growth.
  • Assystem won Rolls-Royce SMR momentum, plus GBE-N, MoD, and FRAM roles.

What critics are saying

  • International revenue fell 7.1% in Q1 2026, hurt by India, Saudi Arabia, and currencies.
  • Eighty-one percent nuclear concentration exposes Assystem to French and UK program slippage.
  • Wylfa SMR or Aval du Futur delays would damage backlog, hiring, and margins.

What makes ASSYSTEM unique

  • Nuclear made 81% of H1 2026 revenue, anchoring Assystem's specialization.
  • June 24, 2026 CPS2 Tier 1 status embedded Assystem in UK nuclear procurement.
  • Mactech's 2025 acquisition and 2026 Cotentin hiring deepened nuclear delivery capacity.

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.
