The organization executed a term sheet agreement to purchase roughly 12.5% of Carester SAS, with investment partner InfraVia acquiring an identical stake. Transaction completion is projected within 30 days, subject to due diligence completion and finalization of binding documentation.
The total investment value is estimated at approximately €40 million. This transaction grants USAR oxide offtake privileges, licensing rights to Carester’s technical expertise and proprietary intellectual property, while integrating operations with Carester’s Lacq, France production facility — presently under development and scheduled to commence operations by late 2026.
Under the agreement, USAR commits to providing Carester with heavy rare earth feedstock extracted directly from its Round Top mineral deposit in West Texas.
The Lacq facility is being developed as one of Europe’s most comprehensive rare earth production hubs. The site will combine processing operations, metal and alloy manufacturing, and magnet production capabilities. USAR’s LCM Europe division has outlined plans for a 3,750 metric ton annual capacity metal and alloy production plant at this location.
Strategic Importance of the Partnership
China maintains control over approximately 85% of worldwide rare earth processing infrastructure. This market concentration has evolved into a strategic vulnerability in international trade relations, with Chinese authorities utilizing it as negotiating leverage against Western industrial interests.
Rare earth elements — critical components in applications spanning electric vehicles to military aircraft — present significant sourcing and processing challenges outside Chinese territory. USAR represents one of multiple Western enterprises working to disrupt this paradigm.
The Carester transaction enhances USAR’s strategic positioning as a midstream processor within European markets. William Blair, which confirmed its Outperform assessment on Thursday, noted the investment positions USAR to become a significant contributor to global processing capacity outside China and may facilitate additional European governmental backing.
Wall Street analysts collectively maintain a Strong Buy consensus rating on the stock, with price projections spanning $25 to $45. Roth/MKM recently adjusted its target downward to $25 from $35, while Canaccord revised to $29 from $33, with both firms attributing the changes to valuation recalibrations rather than operational concerns.
Latest Corporate Developments
USAR has maintained an active development schedule. Earlier in 2026, the company launched its commercial-scale magnet manufacturing line in Stillwater, Oklahoma, with initial customer shipments of sintered neodymium-iron-boron magnets anticipated during Q2 2026.
The enterprise also established a reciprocal sales and distribution partnership with Arnold Magnetic Technologies, and during January revealed a nonbinding letter of intent with the Commerce Department for approximately $1.6 billion in potential financing support.
Notwithstanding Thursday’s decline, USAR stock has surged 128% throughout the preceding 12-month period. Shares traded near $16.69 during early Thursday sessions, down roughly 2.8%, generally tracking weakness observed throughout broader market indices.
The latest individual analyst rating published on the stock carries a Hold recommendation with a $14.50 price objective, though the aggregate analyst consensus remains decidedly more optimistic.
