VALLOUREC WINS FIVE CONTRACTS
FOR OCTG PRODUCTS IN INDONESIA

Meudon (France), on 25 March 2026 - Vallourec, a world leader in premium seamless tubular solutions, announces that it has signed two contracts in February 2026 for 14,000 tons of OCTG products, which are part of a series of five contracts signed recently with different operators in Indonesia. These orders represent a total volume of approximately 36,000 tons of premium pipes and connections to support the Oil & Gas operations of around 140 wells in the region.

Primarily located in deep offshore environments, these complex projects illustrate the technical challenges of the Indonesia's energy sector, that requires solutions capable of withstanding high pressures and extreme conditions. To meet these specific requirements, Vallourec will supply a range of its advanced connections, including VAM 21, a leading market standard that delivers safe and reliable performance.

The pipes will be entirely heat treated and threaded at PTCT, Vallourec's subsidiary in Indonesia, providing operators with premium solutions that maximizes local production and brings value to the country.

Jérôme Favre, Senior Vice-President OCTG Services and Accessories Business Line commented: "These successes with different customers highlight the long-standing relationship of trust we have built with key oil & gas players in Indonesia. They confirm the market's recognition of the quality of our products-and in particular the reliability of our VAM 21 connections-in meeting complex technical specifications for offshore and deep offshore environments."
