The divested business, which comprised the high-performance computing, quantum, business computing, and artificial intelligence divisions, generated approximately 700 million euros in revenue in 2025. Until now, it served as a pillar of the Eviden branch, dedicated to the group's products and systems. Following this transaction, Eviden is refocusing on activities deemed more strategic, namely cybersecurity, critical systems, and AI-augmented video analytics. On a pro forma basis, its revenue stands at approximately 300 million euros for the 2025 fiscal year.

With this acquisition, the French State becomes the sole shareholder of Bull, asserting its commitment to securing key expertise in sensitive technological fields, particularly intensive computing and artificial intelligence. This takeover is part of an industrial sovereignty strategy, set against a backdrop of increased competition surrounding critical digital infrastructure.

For Atos, the disposal illustrates the continuation of a strategic refocusing initiated several months ago, aimed at simplifying its portfolio and concentrating resources on higher value-added activities. While the transaction helps clarify the group's positioning and streamline its scope, it also results in the exit of a significant technological asset. Investors are likely to assess the impact in light of the group's financial trajectory and its ability to accelerate growth in its new development areas.
