Atos has won a three-year contract from LCH SA to migrate the clearing house's core financial information systems to the cloud using a SecNumCloud-qualified environment.

LCH SA, part of LSEG, operates from Paris as a global clearing house. The project will move critical systems to cloud infrastructure while maintaining continuity of operations during the transition.

The agreement places Atos in a sensitive part of financial market infrastructure, where system availability and regulatory oversight are central to any technology change. Clearing houses sit at the core of trading and post-trade processing, making the migration of their information systems a closely watched step for the sector.

Migration plan

The programme will run over three years and is intended to proceed without disruption to existing services, reflecting the role of clearing operations in broader market stability.

SecNumCloud is a French qualification for cloud services designed to meet strict security and sovereignty requirements. Its use in this project underlines the pressure on market infrastructure operators to modernise technology estates while staying within regulatory frameworks.

The deal also highlights continued demand in financial services for cloud arrangements that can support heavily regulated workloads. Firms across the sector have been weighing the operational and compliance implications of moving systems that have traditionally remained on dedicated infrastructure.

Market context

For Atos, the contract adds to its work in cloud transformation for regulated environments. The project will draw on its experience in financial information systems and cloud migration.

For LCH SA, the programme forms part of a broader effort to update internal systems. The clearing house linked the move to customer expectations, regulatory requirements and operational resilience.

Executive views

Franck Chartier, Head of France, Atos, said, "This project perfectly illustrates Atos' ability to support financial institutions in their digital transformation while guaranteeing the security and compliance of their information systems."

"Our expertise, our industry knowledge, and our commitment are key to the success of LCH SA's migration to the cloud. We are proud to contribute to the modernisation and migration of such a strategic infrastructure for the European financial market," added Chartier.

Poilvet-Clédière said, "This project with Atos supports the modernisation of our information systems and helps ensure we continue to meet the expectations of our customers and regulators, while strengthening our operational resilience as we move to the cloud."

Atos employs about 59,000 people and reports annual revenue of about €7.2 billion on a pro forma basis following the disposal of its Advanced Computing activities. The group operates in 61 countries under the Atos and Eviden brands.

LCH SA's selection gives Atos a reference project in one of the most tightly controlled areas of European finance, where cloud adoption has often moved more slowly than in other industries because of the need to protect critical operations and satisfy supervisors. The migration is intended to preserve full continuity of operations as those systems move to the new environment.
