PARIS (Azat TV) – Atos Group, a global entity specializing in AI-powered digital transformation, announced today the completion of its sale of Bull, its Advanced Computing activities, to the French State. The transaction, valued at up to €404 million including contingent earn-outs totaling €104 million, signifies a strategic divestiture for Atos.
Bull Advanced Computing Sale Finalized
The sale follows an initial share purchase agreement signed on July 31, 2025. The enterprise value saw a minor adjustment from an initial projection of up to €410 million to €404 million due to a revision in contingent earn-outs from €110 million to €104 million. This adjustment was partly influenced by a change in the transaction perimeter, which now excludes zData, a company focused on Big Data consulting and solutions.
Scope of Advanced Computing Activities
The divested Bull Advanced Computing segment encompasses Atos’s High-Performance Computing (HPC) & Quantum capabilities, alongside its Business Computing & Artificial Intelligence divisions. In fiscal year 2025, this segment generated approximately €0.7 billion in revenue. Previously, these activities were integrated under Eviden, Atos Group’s brand for products and systems.
Atos Refocuses on Core Markets
Following this divestiture, Eviden will now concentrate on cybersecurity products, mission-critical systems, and Vision AI. Its revenue, on a pro forma basis after the disposal of Advanced Computing, stood at around €0.3 billion in fiscal year 2025. This strategic move by Atos Group aims to streamline its portfolio and sharpen its focus on core markets, including cybersecurity, mission-critical systems, and digital services, where the company anticipates strong long-term growth potential.
French State’s Commitment to Sovereign Capabilities
The transaction is structured to ensure continuity for Bull’s clients and employees. The French State’s acquisition of sole ownership of Bull underscores its commitment to maintaining and advancing sovereign capabilities in the critical fields of supercomputing and artificial intelligence. This move is seen as a reinforcement of national strategic interests in advanced technological sectors.
The sale of Bull’s Advanced Computing arm represents a pivotal moment for Atos as it pivots towards its high-growth strategic pillars, while simultaneously bolstering France’s sovereign technological infrastructure.
