AtkinsRéalis' nuclear revenue up 18% to $671M as union calls for fair contract

The Society of Professional Engineers and Associates (SPEA) says AtkinsRéalis' strong second-quarter nuclear results underscore the value of engineers driving that growth. The company's nuclear segment generated $671.2 million in revenue, up 18.3% year-over-year, whilst Nuclear Segment Adjusted EBIT rose 20.8% to $77.0 million. AtkinsRéalis raised its full-year 2026 nuclear revenue outlook to approximately $2.7 billion from $2.5 billion. SPEA's collective agreements with Candu Energy, an AtkinsRéalis subsidiary, expire at year-end. SPEA President Mark Chudak said fair agreements must recognise employees' contributions. The results follow Canada's June nuclear strategy, which targets building up to 10 new large-scale reactors and establishing at least four international markets for Canadian reactor technology by 2040.

AtkinsRéalis secures EDF nuclear framework and names Byron Bright as US president from July 2026

AtkinsRéalis Group has announced Byron Bright will become President, US, on 1 July 2026, succeeding Steve Morriss, who will continue leading the global Minerals & Metals business until year-end. The company has also been appointed by EDF and Sizewell C Limited to a long-term professional services framework for UK nuclear projects. The appointments reinforce AtkinsRéalis' position in nuclear, transport and infrastructure sectors, supporting a multiyear stream of UK nuclear work. However, analysts note earnings may contract from recent levels, with concerns about margin sustainability and reliance on non-cash earnings. Community fair value estimates range between CA$99.37 and CA$117.29, with shares potentially trading 17% above fair value despite recent pullbacks. Total capital raised has reached $295 million across multiple funding rounds.
