Bull, a company focused on advanced computing, has been acquired by the French State from Atos Group in a transaction valued at up to 404 million euros. The move reflects a shift in ownership within France’s technology sector and relates to areas including high-performance computing, artificial intelligence and quantum technologies.

Bull designs and manufactures supercomputers and high-performance servers, including at its production site in Angers, the only facility of its kind in Europe. These systems are used across national defence, industry and research, including applications involving large-scale AI model development, with a focus on performance and energy efficiency.

The acquisition aligns with wider European activity in high-performance computing, including projects such as the JUPITER exascale supercomputer in Jülich, Germany. In France, it also coincides with the development of the “Alice Recoque” supercomputer, intended to support capabilities in simulation, artificial intelligence and data processing.

Bull employs more than 3,000 people, around half of whom are based in France, and reported revenues of approximately 720 million euros in 2025. The transition to state ownership introduces a long-term public shareholder, with the aim of maintaining continuity and preserving technical expertise within the organisation.

The acquisition also ensures that key operations remain based in France, while supporting activity across high-performance computing, artificial intelligence and quantum technologies, from hardware through to software.

With the French State as shareholder, Bull continues its work in these areas within the broader context of national and European technology development.
