Bull: a New Brand to Drive the Future of Advanced Computing

Paris, France – January 29, 2026 – Bull, a leading brand in advanced computing and AI, is officially launched today, marking the return of a historically rooted technology name, reimagined for a new era. Reinvented through a new identity and a clear sense of purpose, Bull is a global leader in high-performance computing, artificial intelligence and quantum innovation, with the ambition to shape a more responsible digital world, through sustainability, sovereignty and real-world outcomes.

The rebirth of Bull represents a strategic milestone on its journey towards becoming a private, independent company, following the signing of the share purchase agreement with the French State on 31 July 2025. The complete transaction, which is expected to close in the first half of 2026, will support Bull in accelerating its vision of the digital future – more powerful, more sustainable, more sovereign and more open.

With a team of over 2,500 engineers and experts, Bull is driving innovation at scale. Rooted in Europe and holding leading positions in Latin America and India, it brings together a strong European and industrial heritage, a world-class R&D supported by 1,500 patents, unique manufacturing capabilities and decades of expertise to enable nations and industries to fully control their AI and data, advancing progress for the benefit of the planet.

Building on more than a century of expertise in computing and data science, Bull is the only European player designing, manufacturing, and deploying both hardware and software, while also delivering strategic services to unlock enterprise value, accelerate scientific research and drive society forward.

From chip integration and interconnects design to AI platforms and applications, Bull masters the full technology stack. It delivers proven industrial robustness for critical sectors such as defense and energy, while minimizing total cost of ownership through world‑leading green HPC performance. This integrated approach enables secure, sustainable, and independent AI at scale.

Emmanuel Le Roux, SVP, head of Bull said “With the launch of Bull, we are reconnecting with our technological heritage to build our future. Our mission is clear: deliver powerful, sustainable, and sovereign computing and AI technologies that enable nations and industries to innovate with confidence and purpose.”
