Assystem is an autonomous engineering firm headquartered in Paris, established in 1966. The company focuses on the design, construction, oversight, commissioning, and management of intricate industrial projects, with a primary emphasis on the nuclear energy sector. It has been instrumental in the execution of all global EPR construction initiatives, including those located at Flamanville in France, Taishan in China, and Olkiluoto in Finland.
In 2020, Assystem recorded revenues amounting to €471.7 million, a decrease from €871.4 million reported in 2013. The workforce numbered over 7,100 employees as of 2021, down from more than 11,000 in 2013. This reduction aligns with Assystem’s strategic decision to concentrate its activities within the nuclear industry while divesting from other sectors such as the automotive industry.
Additionally, Assystem operates within the aerospace sector. The acquisition of Atena, previously a subsidiary of the German company MTU Aero Engines, took place in 2005. Since 2018, the firm has been involved in engineering projects related to the development of the upcoming Flying Whales airship.
In February 2019, the organization underwent a rebranding and adopted the name Expleo Group.
