Sopra Steria completes the acquisition of an aeronautical engineering business from Daher
The deal strengthens the aerospace division of the Annecy-based digital services group. It comes four days after the publication of a third-quarter update accompanied by an upgrade to its growth target for the financial year.
More than 360 employees and €42 million in revenue consolidated as of 31 October
Sopra Steria has completed the acquisition of the “Manufacturing Engineering” business of Daher Industrial Services, a subsidiary of the Daher group, according to a press release published on 2 November 2026. The transaction has been completed: it is neither a negotiation nor an agreement subject to conditions, but an effective transfer of the business within the group.
The scope acquired falls within industrial production engineering applied to aeronautics. Sopra Steria states that it wishes to thereby strengthen its aerospace expertise and significantly increase its capabilities on production processes that it describes as critical.
The business employs more than 360 people and generated revenue of over €42 million in 2025. It has been consolidated into Sopra Steria's accounts since 31 October 2026.
The group places this acquisition within a strategy aimed at offering expertise covering the entire aerospace value chain. It also presents the transaction as a means of strengthening its position as a technological and industrial partner to major players in the sector.
To justify this move, Sopra Steria highlights the acceleration of manufacturing rates in aeronautics and increasingly demanding industrial performance requirements. The acquisition thus brings the group's offering closer to the manufacturing processes themselves, a field distinct from consulting and systems integration, which make up a significant part of its business.
A business integrated into a group with €5.6 billion in revenue
The scale of the transaction becomes clear when compared with the size of the acquirer. Sopra Steria generated revenue of €5.6 billion in 2025 and employs 51,000 people in nearly 30 countries.
The group operates in particular with financial services, defence, space, aeronautics and the public sector. It claims a role in supporting critical infrastructure and the sovereign functions of states, drawing on its activities in consulting, systems integration, business solutions, artificial intelligence and cybersecurity.
The acquisition therefore adds to a portfolio of activities already focused on sensitive sectors, with aeronautics among the areas cited by the group itself. It complements this presence with engineering expertise centred on production rather than on information systems alone.
From an accounting standpoint, the consolidation date adopted falls after the close of the third quarter. The contribution of the acquired business is therefore not included in the quarterly figures published by the group on 29 October 2026, and it will only enter the accounts from the end of October.
A transaction following a third quarter with 7.9% growth
On 29 October 2026, Sopra Steria had published revenue of €1,420.1 million for the third quarter, up 7.9%. Organic growth had reached 4.3%, compared with 3.0% in the first half, and the group had raised its growth target for 2026 for the second time this year.
By construction, an acquisition is not included in the calculation of organic growth, which neutralises scope effects. This acquisition will therefore weigh on published revenue without changing the organic reading of the business.
The aerospace segment had already been reinforced in October: on 22 October 2026, CS Group, Sopra Steria's space subsidiary, presented the integration of a predictive maintenance tool developed by the Italian company Aiko into its Gosmic satellite control suite.
