Vallourec Geothermal Deep Dive

Meudon (France), 15 June 2026 – Vallourec, a world leader in premium steel tubular solutions, will host its Geothermal Deep Dive today at 17:00 CET / 11:00 EDT. A webcast link will be available on Vallourec’s website for those wishing to join virtually.

Key topics to be discussed during today’s presentation include:

• Geothermal energy as a key pillar within Vallourec’s New Energies portfolio. Management will discuss how commercial and market momentum for conventional and next-generation geothermal applications supports Vallourec’s ambition to reach a New Energies contribution to group EBITDA of at least 10-15% by 2030.
  
  
• An overview of geothermal market forces, drivers of geothermal development and cost dynamics. Structurally higher demand for clean, baseload, dispatchable electricity supply, driven by AI data centers, adoption of electric vehicles and the electrification of industry is leading to an inflection point for geothermal energy. Our premium tubular solutions enable next-generation technologies to unlock major scale and cost reductions.
  
  
• Vallourec’s role as a key enabler of conventional and next-generation geothermal development. Vallourec geothermal specialists will outline the complex environments and unique challenges of geothermal wells, with higher temperatures and longer lifetimes compared to oil and gas. Technical specialists will demonstrate how Vallourec’s extensive oil and gas expertise, best-in-class R&D and testing capabilities are leading the way in designing and supplying fit-for-purpose, premium tubular products for geothermal applications.
  
  
• Vallourec’s significant and rapidly growing addressable market opportunity set in geothermal. Management will discuss the key operational and financial metrics differentiating conventional, enhanced and advanced geothermal applications. Vallourec will outline an addressable market in geothermal which could approach 400 thousand tonnes by the end of the decade, equivalent to the market size for premium, seamless tubes of South America or Africa today.

Philippe Guillemot, Chairman of the Board of Directors, and Chief Executive Officer, declared:

“The accelerating momentum in geothermal, especially next-generation technologies, highlights both the relevance of our strategy and the strategic importance of this market within our New Energies portfolio. This strategy, which we initiated in 2022, has been a key success factor in our competitiveness and growth. This was demonstrated on two occasions already this year in the field of next-generation geothermal, with Fervo Energy and XGS Energy placing their trust in Vallourec to enable their ambitious project development plans over the coming years.
Vallourec is enabling scalable, reliable and low-carbon geothermal energy solutions by leveraging its strong track record, premium product offering, leading R&D capabilities and local asset footprint. As demand for clean, baseload electricity, particularly from data centers, continues to accelerate, we are well positioned to support the deployment of next-generation geothermal projects while driving profitable growth and value creation.”
