Press release

VALLOUREC AND VINCI IMMOBILIER ANNOUNCE THE SIGNING

OF A SALE AGREEMENT FOR THE DÉVILLE-LÈS-ROUEN SITE

Meudon (France), July 22, 2025 – Vallourec, a world leader in premium seamless tubular solutions, announces that it has reached a significant milestone in the selling process for its Déville-lès-Rouen (76) site. On Friday, July 11, 2025, Vallourec and VINCI Immobilier signed an exclusive sale agreement for the transfer of this site.

Since 2023, Vallourec Group has undertaken a major decontamination and rehabilitation process of its Déville-lès-Rouen site, thus honoring its commitments to elected officials and administrations. The Group subsequently launched a call for tenders in September 2024 to oversee the sale of the site. Following a highly competitive application phase, Vallourec entered exclusive negotiations in March 2025 with VINCI Immobilier, whose proposal best met the Group’s expectations and aligned with the regional priorities expressed by local officials.

Since then, VINCI Immobilier has been able to refine its project and present it not only to Vallourec, the seller of the site, but also to local institutional stakeholders concerned with the economic development of the municipality and the Rouen metropolitan area. The project led by VINCI Immobilier aligns well with the history and stakeholders’ desires for the future development of the site.

VINCI Immobilier’s project is part of an economic revitalization initiative, transforming the Déville-lès-Rouen site into an attractive business hub designed to offer diverse employment opportunities and spaces suited to the needs of local businesses. It is set to become a true engine of economic and social development. VINCI Immobilier will provide turnkey buildings for local companies and industrial firms, enabling ultimately the creation of 300 jobs.

Furthermore, in collaboration with the municipality and the Métropole Rouen Normandie, part of the site will be rewilded, and 25% of the area will be developed into green spaces, particularly around the Cailly River, which will be restored to its natural state as part of the project. In addition, the disused railroad line will be offered to the Métropole Rouen Normandie as part of the future Cailly urban walkway.

Following this agreement, Vallourec Group and VINCI Immobilier will continue the necessary regulatory steps for the final transfer of the site, expected in 2026.
