Bull has doubled output at its Angers factory. The French company, now fully owned by the state, reopened the expanded site on Thursday to meet surging demand for machines that power artificial intelligence training and scientific simulation. Executives described the move as a direct response to orders that have piled up faster than the plant could once handle.
The expansion cost €80 million. Production capacity jumped from six racks a month to 12. And it could reach 24 racks next year if the current pace of inquiries continues. This single facility stands as the only factory in Europe dedicated to assembling these complex systems. Its growth marks a tangible step in a years-long European push for computing independence.
Chief Executive Emmanuel Le Roux told Reuters that Bull received more orders this year than ever before. The company has secured 15 of the 18 tenders issued by EuroHPC, the European Union body that co-funds supercomputers with member states. Competitors included Hewlett Packard Enterprise. Yet Bull prevailed in the majority.
Two major projects now run in parallel thanks to the added space. France’s Alice Recoque supercomputer requires 94 racks. Finland’s LUMI-AI system, valued at €388 million, represents Bull’s largest contract to date. Executives said the old capacity would have forced them to build one machine at a time. The new line allows both to advance together. Alice Recoque will support nuclear simulation, AI model training and massive data processing for the French Alternative Energies and Atomic Energy Commission. LUMI-AI, set to go live in the second half of 2027 at Finland’s CSC center, forms the sixth AI Factory under the EuroHPC program.
Europe has committed €7 billion between 2021 and 2027 to build out its supercomputer network. The goal remains straightforward. Close the gap with the United States and China in raw computing power. Demand already outstrips supply. Evangelos Floros, EuroHPC’s infrastructure head, said in an earlier Reuters interview that the organization must reject some applications because capacity falls short. The network now includes 19 AI Factories built around roughly a dozen supercomputers, with further expansion planned.
Bull’s story stretches back decades. In the 1980s, after the United States halted shipments of supercomputers to France’s nuclear agency, officials turned to the domestic supplier. Those machines helped simulate nuclear tests. The strategic rationale never disappeared. France completed its purchase of Bull from debt-laden Atos on March 31, valuing the business at up to €404 million. The deal carved out the high-performance computing, quantum and artificial intelligence activities, giving the state full control of a company that generated about €720 million in revenue last year and employs more than 3,000 people.
Le Roux has set an ambitious target. He wants Bull to claim global leadership in supercomputers, a spot currently contested by HPE and Lenovo. The company already dominates in Europe, India and Brazil. To get there it must increase the share of European components. Officials noted that sovereignty content has climbed from roughly 40 percent in the Jupiter system to 70 percent in Alice Recoque. Jupiter, Europe’s first exascale machine, runs at Germany’s Jülich center. Future systems aim for more than 80 percent European value added. That includes Bull’s own BXI interconnect, which replaces Nvidia’s technology in some deals and accounts for about 20 percent of a machine’s value.
Earlier this year Le Roux expressed confidence in Bull’s long-term position. In a HPCwire interview he highlighted growing customer reassurance now that the company sits on solid footing. Buyers commit for many years when they purchase these systems. They need confidence the supplier will remain viable. Bull also manufactures Nvidia NVL72 systems for the European market under license, responding to demand from companies that prefer local production for sovereignty reasons. The firm continues to bring more manufacturing in-house for its general-purpose, cloud and AI lines.
Commercial contracts complement the public tenders. Airbus signed a multiyear deal worth nearly €100 million to expand its simulation capabilities. Bull delivered new infrastructure in Toulouse and Hamburg, tripling the aerospace group’s capacity for aerodynamic design, acoustics and structural analysis. Such wins demonstrate that industrial users beyond government labs also crave more compute. And they want it from a European source.
Yet challenges remain. Global competition stays fierce. Nvidia still dominates accelerator supply in many deployments, though Bull integrates AMD chips in LUMI-AI alongside IBM storage and Nokia networking. Energy efficiency has become a decisive criterion as models grow larger and power consumption soars. Bull executives stress that their designs excel on both performance and consumption metrics.
The Angers expansion does more than add racks. It signals seriousness about scaling. Plans call for four exascale-class machines per year once fully ramped. That pace aligns with the order book and the European roadmap. Bull has also announced plans to hire 500 additional staff, mainly in research and development and data science, to accelerate work on new systems and practical AI use cases for clients.
So the factory reopening carries weight. It turns policy declarations about technological sovereignty into concrete assembly lines. European researchers and companies gain access to machines built on home soil with an increasing proportion of local technology. Rejection rates at EuroHPC may ease as capacity grows. But the gap with American and Chinese hyperscalers will not vanish overnight. Bull’s success will depend on continued wins, further component localization and the ability to deliver machines that match or beat foreign alternatives on price, performance and efficiency.
Le Roux and his team now operate with a stable, long-term shareholder. The French state understands the historical stakes. It also sees the future ones. Artificial intelligence models require ever-larger clusters. Scientific discovery in climate, materials and biology runs on the same infrastructure. Defense applications add another layer of strategic necessity.
Bull has positioned itself at the center of that convergence. The doubled output at Angers buys time and capacity. Whether it proves enough will show in the tenders yet to come and the systems delivered over the next several years. For now, the machines roll off the line faster than before. Europe’s AI ambitions just gained a measurable boost.
