France Acquires Bull Computing Assets

The French State has finalized its strategic acquisition of Bull, a pivotal advanced computing division formerly part of the Atos Group. This significant transaction, valued at up to EUR 404 million (approximately USD 438 million), including performance-based earn-outs, concluded on March 31, 2026. The move underscores France's commitment to bolstering its national capabilities in critical technological domains.

The newly acquired entity, Bull, is a powerhouse in High-Performance Computing (HPC) and Quantum technologies, alongside its robust Business Computing and Artificial Intelligence operations. In fiscal year 2025, Bull reported revenues of roughly EUR 700 million (around USD 810 million) and commands a workforce of approximately 2,500 professionals spread across Europe, Latin America, and India. This acquisition positions the French State as the sole proprietor of Bull, a move designed to safeguard and advance sovereign technological expertise.

Central to Bull's technological prowess are its BullSequana HPC systems, which power some of the world's most advanced supercomputers. Notably, the company operates Europe's only supercomputer manufacturing facility, situated in Angers, France. The French government's decision to intervene stemmed from concerns that these vital national assets might transition to foreign ownership during Atos Group's broader restructuring efforts. The share purchase agreement was initially inked on July 31, 2025, following a confirmed offer.

This strategic acquisition is particularly relevant given the escalating global demand for advanced computing power, driven by advancements in AI, scientific research, and complex data analysis. The HPC market, projected to grow significantly in the coming years, is crucial for national competitiveness and innovation. By bringing Bull under state control, France aims to ensure continued domestic development and access to cutting-edge supercomputing technology, essential for both public sector initiatives and private sector innovation.

Following this divestiture, Eviden, Atos Group's products and systems brand, will concentrate on its core offerings in cybersecurity products, mission-critical systems, and Vision AI. Pro forma revenues for Eviden in fiscal 2025 were approximately EUR 300 million. This strategic realignment allows Eviden to sharpen its focus while Bull embarks on a new chapter under French state stewardship.

The acquisition of Bull by the French State represents a significant step in reinforcing national technological sovereignty. It ensures that critical infrastructure and intellectual property in supercomputing and AI remain within French control, fostering domestic innovation and securing a competitive edge in a rapidly evolving global technology market. The investment highlights a growing trend among nations to protect and develop strategic technological capabilities.
