LCM and Solvay Partner to Supply Samarium to Europe

Less Common Metals (LCM), a newly acquired subsidiary of USA Rare Earth, has signed a strategic agreement with chemicals company Solvay to supply samarium materials to Permag for the European market and Permag’s global customers.
Under the deal, LCM will apply its metallization expertise to oxides concentrated and separated by Solvay, producing samarium feedstock used in high-performance magnets and magnetic assemblies.
Samarium-based materials are critical for high-temperature, precision magnets deployed in defense, automotive, aviation, clean-energy and industrial applications; the collaboration aims to meet projected demand over the next three to five years and improve supply-chain resilience in Europe.
USA Rare Earth completed its acquisition of LCM on November 18, 2025, and expects LCM to also supply alloy feedstock for the company’s Stillwater, Oklahoma neo-magnet plant, which remains on track for commissioning in the first quarter of 2026.
Company executives say the partnership strengthens a magnet-to-mine supply chain linking allied industrial bases and advances efforts to establish a more secure domestic and transatlantic rare-earth ecosystem.
