Valneva SE Consolidates French Operations, Closing Nantes Site and Moving Registered Office to Lyon

VALN
November 26, 2025

Valneva SE announced that it will consolidate its French operations by closing its Nantes site and moving its registered office back to Lyon, the city where the company was originally founded. The company will also centralize all research and development activities at its Vienna headquarters, where it currently houses more than 200 R&D employees.

The announcement did not disclose a specific timeline for the Nantes closure or the office relocation, but it confirmed that the company will support affected employees through transition assistance and redeployment opportunities. The move brings Valneva’s French administrative functions into Lyon, a recognized vaccine hub that hosts major players such as Sanofi Pasteur and the Mérieux group, while the Vienna site will continue to drive the company’s global vaccine pipeline.

Strategically, the consolidation is intended to streamline operations and reduce overhead costs. By concentrating administrative functions in Lyon and centralizing R&D in Vienna, Valneva can eliminate duplicate support functions, lower real‑estate expenses, and accelerate decision‑making across its vaccine development programs. The company’s leadership has emphasized that the move aligns with its long‑term plan to focus resources on high‑impact vaccine candidates, including the Lyme disease vaccine partner with Pfizer and the Shigella candidate.

Valneva’s Q3 2025 financial results provide context for the decision. The company reported €127 million in revenue for the first nine months of 2025, up 9% from the prior year, and a product‑sales increase of 6.2%. However, operating losses of €53.9 million and negative adjusted EBITDA of €37.7 million reflected higher R&D spend and the absence of a one‑time gain from a prior voucher sale. Management reiterated its 2025 guidance of €155–170 million in product sales and €165–180 million in total revenue, signaling confidence that the consolidation will help stabilize costs and support the company’s projected profitability from 2027 onward.

The consolidation is expected to have a modest but meaningful impact on Valneva’s cost structure, potentially freeing up capital that can be redirected toward vaccine development and commercialization. While the immediate financial effect is not quantified, the move is part of a broader strategy to improve operational efficiency and position the company for sustained growth in a competitive specialty‑vaccine market.
