Atos Completes Sale of Bull Advanced Computing Business to French State to Strengthen Strategic Focus

(IN BRIEF) Atos Group has finalized the sale of its Bull advanced computing division to the French State for up to €404 million, including earn-outs. The business, which includes high-performance computing, quantum, and AI activities, generated around €0.7 billion in revenue in 2025. The divestment is part of Atos’ strategy to refocus on core areas such as cybersecurity, mission-critical systems, and digital services, now consolidated under its Eviden brand. The deal also reflects France’s commitment to strengthening its sovereign capabilities in supercomputing and AI, with the State becoming the sole owner of Bull while ensuring continuity for clients and employees.

(PRESS RELEASE) PARIS, 1-Apr-2026 — /EuropaWire/ — Atos Group has completed the sale of its Bull advanced computing business to the French State in a transaction valued at up to €404 million, including contingent earn-outs of €104 million. The move represents a key milestone in the company’s broader strategy to streamline operations and focus on core growth areas.

The divestment follows a share purchase agreement initially signed in July 2025. Since then, the scope of the transaction has been adjusted to exclude zData, a specialist in Big Data consulting and solutions. This revision led to a slight reduction in the potential earn-out component and overall enterprise value compared to earlier estimates.

The transferred business includes Atos’ Advanced Computing activities, which cover high-performance computing (HPC), quantum technologies, as well as business computing and artificial intelligence solutions. These operations generated approximately €0.7 billion in revenue during the 2025 financial year and were previously part of the company’s Eviden division.

Following the sale, Eviden’s scope has been reshaped to concentrate on cybersecurity products, mission-critical systems, and Vision AI solutions. On a pro forma basis, this revised portfolio generated around €0.3 billion in revenue in 2025.

The transaction forms part of Atos’ ongoing transformation plan, aimed at sharpening its strategic focus and reinforcing its presence in areas with stronger long-term growth prospects. By divesting its advanced computing operations, the company intends to allocate resources more effectively toward cybersecurity, digital services, and critical infrastructure technologies.

From a national perspective, the acquisition highlights France’s commitment to maintaining and advancing sovereign capabilities in high-performance computing and artificial intelligence. With the completion of the deal, the French State becomes the sole shareholder of Bull, ensuring continued investment and development in these strategic sectors.

Atos emphasized that the transaction has been structured to ensure continuity for customers and employees, maintaining service quality and operational stability throughout the transition.
