VALLOUREC CONFIRMS ITS PLATINUM MEDAL FROM ECOVADIS FOR SUSTAINABILITY PERFORMANCE

Meudon (France), May 11, 2026 - Vallourec, a world leader in premium seamless tubular solutions, announced today that it has once again confirmed a Platinum medal from EcoVadis, a global leader in business sustainability assessments.

Vallourec scored 86 out of 100, securing its position in the top 1% of companies globally assessed by EcoVadis. This result reflects the maturity and the steady progress of the Group, up from a score of 78 in 2023, representing an 8-point improvement over three years.

The EcoVadis assessment takes into account the robustness of our commitments, policies and concrete actions across four key pillars: Environment, Labor & Human Rights, Ethics and Sustainable Procurement. More than 130,000 companies globally have been rated by EcoVadis.

EcoVadis' business sustainability ratings are based on international sustainability standards such as the Ten Principles of the UN Global Compact, the International Labour Organization (ILO) conventions, the Global Reporting Initiative (GRI) standards and the ISO 26000 standard. The ratings provide an evidence-based analysis on performance and an actionable roadmap for continuous improvement.

Philippe Guillemot, Chairman of the Board of Directors and Chief Executive Officer of Vallourec, commented:"Confirming our Platinum medal from EcoVadis and remaining in the top 1% of companies globally assessed validates Vallourec's sustainability performance. This recognition reflects the depth of a long term commitment across all our teams and entities. It also reinforces our responsibility: to continue progressing toward our objectives with the same rigour, and to remain a reference player for our stakeholders."
