Sopra Steria has appointed Laura Chaubard to lead its Defence, Security and Space vertical, effective September 1, 2026, as the Group accelerates its sovereignty agenda amid rising European defence spending. Chaubard, a graduate of École Polytechnique and a General Engineer of Armament, will join the Group Executive Committee. The appointment reinforces Sopra Steria's ambition to be a leading European partner in critical systems at a time when technological sovereignty is becoming a major strategic issue.

The Defence, Security and Space vertical accounted for 13% of the Group's revenue in 2025. It brings together Sopra Steria's most strategic activities in service of the armed forces, governments, and major critical infrastructure. The vertical designs and integrates critical systems, including command, intelligence, cybersecurity, sovereign data processing, ground segments, and space applications.

Strategic Context and Acquisitions

Europe is increasing its spending on defence, security, and access to space at a rate not seen in thirty years, asserting its ambition for strategic autonomy. The choice of players that will design and maintain critical systems—and their degree of independence from non-European players—is becoming a central question for European strategy.

Sopra Steria's vertical draws on proven strengths and strategic acquisitions. CS Group, a wholly owned subsidiary, is a recognised integrator of critical defence and security systems. In May 2026, the Group completed the acquisition of Starion and Nexova, which strengthen its sovereign, secure capabilities in space and cybersecurity.

Key Vertical Metrics

Rajesh Krishnamurthy, CEO of Sopra Steria, said: "Ambitions are judged by the resources you put behind them." The Group aims to make defence, security, and space one of the engines of its growth in the years ahead.

The disclosure was made in accordance with Article L.233-8 II of the French Commercial Code and Article 223-16 of the General Regulations of the Autorité des Marchés Financiers.

Share and Voting Rights Details

The data provided by Sopra Steria Group distinguishes between the theoretical number of voting rights and the number that can actually be exercised. This distinction often arises due to shares being held as treasury stock or other restrictions that limit voting capabilities.

The theoretical number of voting rights is calculated based on all shares carrying voting rights, including those that may be suspended from voting. The exercisable voting rights represent the total number of votes that can actually be cast at shareholder meetings.

Sopra Steria Group is listed on Euronext Paris under the ticker SOP. The company operates as a major technology player in Europe, providing consulting, digital services, and software solutions.
