Paris, France – March 31, 2026 – Bull, a leader in advanced computing and AI, announces the completion today of the French State’s acquisition of 100% of the capital of Bull from Atos Group. Agreed with Atos Group in July 2025 for an enterprise value of up to 404 million euros, this transaction marks a major step forward for French and European technological sovereignty, particularly in the fields of high‑performance computing, artificial intelligence and quantum technologies.
A historic brand in the sector, Bull is a leading actor in the design and manufacture of supercomputers and high‑performance servers, as well as enterprise servers, software solutions, AI use cases and innovations in quantum computing. With a long‑standing R&D footprint, Bull also operates the only supercomputer manufacturing plant in Europe, located in Angers. The supercomputers produced there meet the most demanding needs of national defence, industry and fundamental research, and are also essential for training and deploying artificial intelligence models. They are recognised for their performance and energy efficiency—two decisive criteria for training large AI models.
This acquisition forms part of an ambitious strategy for high‑performance computing in Europe, and particularly in France. It comes as the successful delivery of the exascale supercomputer JUPITER in Jülich, Germany, under the European EuroHPC programme, positions France and Europe at the cutting edge of research and innovation. It also accompanies the launch of the construction of Alice Recoque, the next French supercomputer, which will strengthen national capabilities in simulation, artificial intelligence and massive data processing, in support of technological sovereignty.
Bull brings together more than 3,000 professionals and experts, half of whom are based in France, and generated revenues of c. 720 million euros in 2025.
The French State’s acquisition of Bull provides the company with a long‑term public shareholder, ensuring stability, strategic continuity and the preservation of critical expertise in support of a French and European excellence‑driven industrial sector.
Roland Lescure, Minister for the Economy, Finance and Industrial, Energy and Digital Sovereignty of France, stated:
“With the completion of this acquisition, the French State as shareholder reaches a decisive milestone for France’s technological sovereignty. The delivery of JUPITER and the launch of Alice Recoque illustrate our ability to innovate and position ourselves as a major actor in high‑performance computing and AI in France, in Europe and worldwide. The renewal of Bull, which we will actively support, will mark the beginning of a new era for the strategic sector of high‑performance computing and artificial intelligence. Together, we will build a competitive French and European offering that creates jobs, added value and excellence.”
Sébastien Martin, Minister Delegate for Industry of France, stated:
“The takeover of Bull’s activities by the State ensures that critical capabilities and expertise — particularly for the defence industries — remain in France, and safeguards our industrial sovereignty. I have full confidence in Bull and its employees to continue on their path of growth and technological leadership, in supercomputing and artificial intelligence, from electronic components to software layers.”
Anne Le Hénanff, Minister Delegate for Artificial Intelligence and Digital Affairs, stated:
“The State’s entry into Bull’s share capital marks a decisive step for our digital sovereignty. At a time when artificial intelligence and quantum technologies are profoundly reshaping technological balances, France is equipping itself with a leading industrial player in high‑performance computing. By supporting the emergence of Bull, we are choosing strategic independence. It is a strong signal: that of a country that invests, that protects its expertise, and that is determined to remain sovereign in the technologies that will shape the world of tomorrow.”
Emmanuel Le Roux, Chief Executive Officer of Bull, stated:
“The revival of Bull as an independent company supported by the French State marks a decisive step in our history. With a long‑term strategic shareholder, we are strengthening our position as a trusted industrial partner across the entire value chain of high‑performance computing, quantum computing and artificial intelligence. Thanks to our integrated pipeline—from design to manufacturing—as well as sustained investment in R&D and the deployment of AI use cases with our 300 data scientists, we have a unique ability to innovate with rigour and speed. This new structure gives us the agility required to respond to the challenges of a market undergoing profound transformation driven by the rapid evolution of AI, and thus to provide our customers with sovereign, high‑performance and sustainable technologies.”
