• 2026-10-02 Bull Expands Supercomputer Manufacturing with €80M Angers Redevelopment · HPCwire
  Angers 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.
• 2026-09-22 SiPearl Delivers 1st Rhea1 CPU Samples to Bull for JUPITER Supercomputer · HPCwire
  SiPearl shipped the first Rhea1 samples to Bull for integration onto the BullSequana XH3000 platform that forms JUPITER's CPU cluster module, the first delivery of a European-designed processor into a European-built exascale system and SiPearl's first revenue-bearing order. It's a concrete step on the domestic-substitution question this graph already flags for Rhea1: a European host CPU moving from lab benchmarking into an actual EuroHPC machine rather than staying a roadmap item.
• 2026-09-17 Bull Beats Out HPE For Next-Gen Lumi AI Supercomputer · The Next Platform
  EuroHPC and CSC Finland picked Bull over incumbent integrator HPE to build the LUMI-AI upgrade partition, with delivery slated for the second half of 2027. Worth tracking on the graph because it's a rare case of an existing HPE/Slingshot machine losing its re-up bid to a European vendor running its own BXI interconnect, which fits EuroHPC's stated preference for buying European where it can.
• 2026-09-14 Bull awarded €31m contract with AEMET to deliver infrastructure for weather forecasting supercomputer · Data Center Dynamics
  A 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.
• 2026-03-31 French state completes its acquisition of Bull from Atos · Atos Group
  The 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.
