Gecina – Leasing activity | Press release – October 12, 2026

Two major long-term leases for Gecina’s portfolio in La Défense

Gecina has signed two new major long-term leases in Paris La Défense for Building B and Adamas, both adjacent to T1/Shape, with firm terms of over 11 years (for a total of 29,000 sq.m). These transactions ensure full occupancy for both buildings and confirm this submarket’s solid fundamentals for the best assets.

• Gecina has signed an 11.5-year firm lease with an international leader in nuclear energy for 100% of Building B (21,000 sq.m), adjacent to the T1 Tower (now Shape), effective mid-2028. The tenant chose this asset for its large, bright and modular floorplates, which are easy to fit out and adapt to new ways of working, as well as its strong energy performance, already aligned with the 2040 target from the Tertiary Decree.
• Alongside this, Gecina has signed an 11-year firm lease with the current occupier of Building B, a security technology company, which will relocate to the adjacent Adamas building (8,000 sq.m). This transaction brings Adamas to full occupancy and illustrates Gecina's ability to proactively leverage the scale and diversity of its portfolio, offering tailored solutions as its tenants’ needs evolve.
• Together, these two new large transactions confirm the attractiveness of Paris La Défense, where take-up rose 25% over the first nine months of 2026 versus the same period of 2025. A dynamic mixed-use submarket, it benefits from an unmatched public transport hub (the largest outside Central Paris, serving all forms of mobility, with one third of the Paris Region's population set to live within 30 minutes of Paris La Défense by 2031) and confirms the ability of the best assets to attract and retain tenants in this submarket.

Marie Caniac, Deputy CEO in charge of the Office Division: “We are pleased to welcome two leaders in their respective markets to our Paris La Défense assets through these two new leases. This reflects our active asset management in action: converting our precise understanding of our tenants' needs into tailor-made solutions that secure long-term full occupancy across the portfolio in operation in this area”.
