UK-based Less Common Metals (LCM), which was recently acquired by USA Rare Earth, has signed a supply agreement with Belgian chemical company Solvay and Arnold Magnetic Technologies, a subsidiary of Compass Diversified, to provide rare earth materials for Arnold’s permanent magnet production.
LCM’s metal and alloy-making capabilities will ensure a reliable source of high-quality rare earth materials from outside China for Arnold’s production.
USA Rare Earth completed its acquisition of LCM in November 2025. LCM continues to serve its global customer base while providing alloy feedstock for its new parent’s Stillwater, Oklahoma magnet manufacturing facility, which is scheduled to be commissioned during the first quarter of 2026.
USA Rare Earth intends to establish domestic rare earth and critical minerals supply, extraction and processing capabilities to supply its magnet manufacturing plant and sell surplus materials to third parties.
“This collaboration exemplifies the type of industrial partnerships that are rebuilding strength and resilience across the rare-earth ecosystem outside of China,” said Barbara Humpton, CEO of USA Rare Earth. “LCM’s role demonstrates the strategic importance of secure, reliable sourcing, and how collaboration between trusted partners can guarantee sustainable access to critical rare earth materials for global magnet manufacturers.”
