Capgemini has acquired 100% of the share capital of SEIMAF, an industrial engineering and technical consulting group operating in the energy, environmental and industrial sectors that specializes in nuclear. This acquisition arrives as Europe focuses on nuclear energy extension and expansion, especially in France and the United Kingdom.

SEIMAF will reinforce Capgemini’s in-demand specialist engineering and technical capabilities to support the industry. It will also bolster the Group’s status as a partner to clients in the nuclear domain, as well as other industrial sectors.

Founded in 1994 and headquartered in Paris, SEIMAF’s team of over 100 design engineers and technicians located in France, the UK and Romania, supports its clients in the nuclear, energy, and industrial sectors, with their productivity improvement processes, mainly in the fields of general installation and mechanical design. They provide solutions in process, studies, and operations management. Their expertise covers industries that produce, transform, distribute, and supply energy in all its forms. 

“As we have a number of industrial clients in common, this acquisition is a natural fit for Capgemini and reinforces the Group’s status as a trusted strategic partner to global industrial organizations,” comments Angélique Lallouet, executive director of Capgemini Engineering in France. “SEIMAF’s specialist expertise will strengthen our engineering and design teams enabling clients to leverage and thrive in the energy transition, as we enter an area of industrial growth powered by efficient and sustainable energy.”

“Capgemini is at the heart of the global energy transition, with a long heritage and well-established track record of supporting industrial organizations in their business and technology transformation journeys, especially leading nuclear players in France,” says Gilles Glad, CEO of SEIMAF. “The breadth and depth of the Group’s global capabilities will allow our teams to bring their deep expertise to some of the most cutting-edge industrial projects.”
