Europe’s AI buildout is getting a bigger factory floor. French state-owned supercomputer maker Bull has doubled production at its Angers plant as demand for regional computing capacity rises.
French state-owned supercomputer maker Bull has doubled output at its Angers plant to 12 racks a month from six, with capacity potentially rising to 24 racks a month in 2027 if demand continues to grow.
The expansion matters beyond France. Bull is a major supplier to Europe’s supercomputing network, and its larger production footprint strengthens the region’s ability to assemble more high-performance computing systems locally as governments push to reduce dependence on foreign infrastructure.
Bull’s Angers plant doubles output
Reuters reported that Bull spent €80 million (about $90 million) expanding its Angers site. CEO Emmanuel Le Roux said Bull has received more orders this year than ever before and won 15 of 18 EuroHPC tenders.
The extra capacity is already supporting major European systems. Bull is assembling France’s 94-rack Alice Recoque supercomputer and Finland’s €388 million (about $437 million) LUMI-AI, projects executives said would not have been possible before the expansion.
Bull also built JUPITER in Germany, Europe’s first exascale supercomputer.
Angers is becoming a broader AI infrastructure hub
Bull said the new building is part of a wider redevelopment due for completion in 2028. The 20,000-square-metre site includes 10,700 square metres for production, and Bull expects 30% higher productivity alongside the doubled capacity.
The company is also launching an Open Factory program to help European AI, advanced-computing, and quantum companies move from R&D into large-scale production.
Bull noted that the program could support future AI GigaFactories and neocloud providers, with its Foxconn partnership already serving as an early example. The two companies plan to design and manufacture Nvidia Vera Rubin NVL72-based AI servers in Europe.
What eWeek found: Europe can build more, but memory remains a gap
Europe is gaining more control over AI and HPC infrastructure as local assembly and component sourcing expand. Memory, however, remains a major supply-chain dependency.
Le Roux told Reuters that Bull can now source about 70% of the components in its machines from Europe, up from roughly 20% to 30% five years ago. Boards, interconnects and cooling systems can increasingly be sourced within the region, while European processor projects include SiPearl, Vsora and Openchip.
Memory remains the weak point. “The problem is memory. We don’t see anything coming,” Le Roux said. Samsung, SK Hynix and Micron produce more than 90% of memory worldwide, according to Reuters.
That leaves Europe dependent on non-European suppliers for a component that becomes even more important as AI systems require larger amounts of high-bandwidth and conventional memory.
Area | What the sources show | EMEA implication |
| Assembly capacity | Bull increased output from 6 to 12 racks a month and could reach 24 in 2027 | Europe can build more large-scale systems inside the region |
| European components | Bull says about 70% of components in its systems can now be sourced in Europe | Dependence has fallen across boards, cooling and interconnects |
| Processors | European suppliers are making progress; processors account for 10% to 20% of a supercomputer’s value | Local processor options are improving, but CPUs are only one part of the supply chain |
| Memory | More than 90% of global memory comes from Samsung, SK Hynix and Micron | A major hardware dependency remains outside Europe |
For European enterprises, cloud providers and research organisations, Bull’s expansion could make more locally assembled AI and HPC capacity available across the region.
It also shows the limit of Europe’s sovereignty push: building more systems at home does not remove every external dependency, and memory remains one of the hardest gaps to close.
