USA Rare Earth to Strengthen its European Partnership
USA Rare Earth, Inc. announced that it has entered into definitive agreements to acquire strategic minority stakes in Carester SAS, a French leader in rare earth processing and separation.
InfraVia – acting through its Critical Metals Fund, seeded by the French State as an anchor investor alongside private institutional capital – is acquiring a similar stake in Carester alongside USA Rare Earth. The agreements would finalize the strategic investment and commercial framework the parties announced in April 2026, the information said. “In addition to targeting healthy returns, USA Rare Earth and its subsidiary Less Common Metals Europe will have the ability to purchase a portion of Carester’s oxide output from its Caremag facility. USA Rare Earth will have access to Carester’s engineering capabilities and related intellectual property for separation, processing, and recycling. In turn, Carester will have access to USA Rare Earth feedstock sources, including Serra Verde and the Round Top deposit in Texas.”
