VALLOUREC ANNOUNCES MULTI MILLION DOLLAR INVESTMENT
IN A NEW PREMIUM THREADING LINE IN YOUNGSTOWN, OHIO

Youngstown, Ohio – November 10, 2025 – Vallourec, a world leader in premium tubular solutions, announced today a $48 million investment to expand its operations in Youngstown, Ohio. This strategic initiative is part of a broader commitment to U.S. manufacturing, with over $1.5 billion invested in the United States over the past 15 years.

The investment will support the creation of a new Premium Threading Line within Vallourec’s existing steel making, rolling and finishing operations. This addition will offer a competitive, fully integrated domestic manufacturing route and strengthen Vallourec’s position in the Oil Country Tubular Goods (OCTG) market in the US. This new line will increase capacity to thread VAM® high-torque connections, which are increasingly used in onshore wells with long laterals. This development marks a major milestone in Vallourec’s ongoing commitment to U.S. manufacturing excellence and energy innovation.

Construction began in July 2025 and is expected to be completed by early 2027, with no disruption to current operations. Once operational, this new line will create 40 full-time-equivalent positions, expand the local supply chain, and support the regional energy industry, further reinforcing Ohio’s industrial ecosystem.
