Atos has acquired a 50 percent stake in MSL Group, in order to bolster its specialist IT capabilities for large events.
Under the deal, for which a value has not been disclosed, Atos will gain the option of an outright acquisition of MSL at a later stage.
MSL provides real-time data systems to large sports events, and has a 15 million annual turnover.
The acquisition grows Atos' sports events capabilities. Atos is already the lead IT provider to the Olympics and Paralympics, including London 2012.
Atos and MSL have worked together on IT at sports events since the 1992 Barcelona Olympics, and they also work regularly on tennis events. By combining, the companies will provide IT and data services for timing and scoring, information diffusion for the media, TV graphics, games management, and system integration.
"Today's announcement marks a major milestone in our strategy to be the global IT leader for major events," said Patrick Adiba, head of major events at Atos. "We have a strong heritage in this specialised IT, having delivered 50 successful global events worldwide since 1989."
Staff at Atos major events and MSL Group are based in Spain.
