As of April 1, 2026, these three assets—previously held by Covivio (in partnership with Crédit Agricole Assurances for the Hélios 1 site)—are now owned 51% by Covivio and 49% by real estate funds managed by Blue Owl Capital.

Located at the heart of the world-class Paris-Saclay innovation hub, these sites represent Thales' largest global footprint, designed to accommodate nearly 6,000 employees across more than 126,000 sqm.

The transaction values the entire complex at 503 million euros. For Covivio, the deal represents the equivalent of 138 million euros in group-share sales and contributes to the rebalancing of its portfolio toward the hospitality sector.
