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

Assystem reported consolidated revenue of โ‚ฌ328.5 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 โ‚ฌ201.1 million, led by strong momentum in nuclear new-builds and fuel cycle activities. International operations generated โ‚ฌ127.4 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 โ‚ฌ165.8 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 โ‚ฌ102.6 million, driven by momentum in fuel cycle activities, new-builds and digitalisation. International revenue declined 7.1% to โ‚ฌ63.2 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.
