- Bull Expands Supercomputer Manufacturing with €80M Angers Redevelopment · HPCwireAngers is the one European plant assembling Eviden's BullSequana systems, including the Alice Recoque and LUMI-AI builds already tracked here, so this €80M capacity doubling (due 2028) is a concrete signal on whether those deliveries stay on schedule. It also surfaces a new Foxconn partnership to build NVIDIA Vera Rubin NVL72 AI servers in Europe, relevant to the EU domestic-substitution question raised elsewhere in this dataset.
- Bull awarded €31m contract with AEMET to deliver infrastructure for weather forecasting supercomputer · Data Center DynamicsA four-year, €31m contract for AEMET's Madrid-hosted forecasting supercomputer, awarded to Bull only months after the French state completed its buyout of Bull from Atos — a data point on Bull's post-acquisition order book alongside its Mimer and LUMI-AI wins earlier this year.
- French state completes its acquisition of Bull from Atos · Atos GroupThe state becomes sole owner of Bull's HPC, quantum and AI divisions for up to 404 million euros, nine months after the July 2025 purchase agreement, formalizing Bull as a sovereign supplier rather than a subsidiary of a financially troubled parent. Bull's BullSequana platform underpins JUPITER, so this is a change of ownership sitting directly upstream of an existing exascale system in this dataset, not just a balance sheet event.
