In 1995, Dominique Louis oversaw the initial public offering of Assystem which had a staff of 3,000 engineers and technicians and an annual revenue of €250 million at the time. The phasing out of nuclear power in the late 1990s marked the beginning of Assystem’s transformation, whereupon it would diversify into the aeronautics and automotive sectors and develop internationally. In 2017, Dominique Louis decided to refocus the Group’s business on its historic areas of expertise: nuclear power and complex infrastructures. For this purpose, Assystem sold 60% of its outsourced R&D business to the Ardian investment fund and acquired a 5% stake in Framatome to confirm the Group’s role in the French nuclear sector. In 2018, Dominique Louis and his advisor Jean-Louis Ricaud, published a book entitled "2050 : la France sans Carbone” (2050: A Carbon-Free France), which set out their uncompromising review of trends in global CO2 emissions, and the solutions to be deployed to ensure access to competitive, decarbonised energy for all. In 2021, Dominique and Jean-Louis Ricaud published their second book, “Energie nucléaire, le vrai risque” (Nuclear energy, the real risk), in which they demonstrate the role of nuclear power as an all-important solution to the climate challenge. Dominique Louis was made a Chevalier (Knight) of the Légion d’honneur (Legion of honour).
