Bull

Bull is the division of the French IT group Atos that encompasses its strategic activities, notably including supercomputers used for nuclear deterrence and quantum computing. It has a history of being a French champion in computing, even requiring nationalization in the past. Bull is newsworthy because the French state has finalized its acquisition of this division from Atos for a valuation of up to €404 million. This acquisition, initiated with a firm offer in June 2025, makes the state the sole shareholder of Bull. The move is motivated by a desire to maintain French technological sovereignty, particularly in sensitive areas like supercomputing and nuclear deterrence. The acquisition aims to protect Bull's expertise, which was considered at risk due to the financial instability of Atos. This event is significant as it represents a renewed commitment by the French government to control and safeguard key technological assets.
