Nuclear activities drove 2.5% organic growth in the first half, led by France and the United Kingdom, while currency headwinds and weaker activity in some international markets weighed on reported revenue growth.
Assystem reported first-half 2026 consolidated revenue of €328.5 million, up 0.6% from €326.4 million a year earlier, with organic growth of 2.5% partly offset by a 1.9% negative currency effect. Nuclear activities recorded 8.0% organic growth and represented 81% of group revenue, up from 76% in the first half of 2025, supported notably by France and the United Kingdom. Revenue in France rose 4.2% to €201.1 million, entirely on an organic basis, as momentum in nuclear new-build and fuel cycle work was driven by the EPR2 and “Aval du futur” programmes. International revenue fell 4.5% on a reported basis to €127.4 million, but was stable organically, as currency weakness linked to the pound sterling, Indian rupee and Saudi riyal offset stronger activity in the United Kingdom. The group said growth in the United Kingdom remained robust in civil nuclear engineering and defence, helped by the first effects of contracts won in late 2025 and early 2026, with a stronger contribution expected in the second half. By contrast, business volumes continued to decline in the MECA region and in India, reflecting the end of the Akkuyu project in Turkey, a demanding comparison base, fewer siting studies, contract phasing and the impact of the conflict in the Middle East on regional economic conditions. Assystem maintained its full-year 2026 targets for organic consolidated revenue growth of 2% to 4% and an EBIT-A margin of around 7% of revenue, while saying it could not yet measure the potential effect of the conflict in the Middle East on those goals. Shareholders also approved a €1.0 per-share dividend for 2025, for a total payout of about €14.8 million, paid on July 9 after an ex-dividend date of July 7.
