Exclusive: Pentagon Seals $400 Million Strategic Stake in US Rare Earth Leader
WASHINGTON – In a strategic move to shore up America’s critical minerals supply chain, the Pentagon will acquire $400 million worth of convertible preferred shares in Mountain Pass Materials, positioning the Defense Department as the largest shareholder in the nation’s sole integrated rare earth producer.
The transaction, expected to close imminently, will translate to a 15% ownership stake in the California-based company, according to a joint statement released Tuesday.
Government documents indicate provisions for additional common stock purchases in the future, suggesting potential multibillion-dollar follow-on investments to accelerate domestic rare earth capabilities.
Concurrently, Mountain Pass unveiled plans to construct a rare earth permanent magnets plant – a critical component for electric vehicles and defense systems – targeting initial production by 2028. The facility will push the company’s annual magnet output capacity to 10,000 metric tons, though a location remains undetermined.
Securing this vital supply line, the Pentagon finalized a 10-year off-take agreement featuring price floor protections. The deal is further bolstered by $1.15 billion in strategic funding coordinated with Wall Street institutions JPMorgan Chase and Goldman Sachs.
Founded in 2017, Mountain Pass operates North America’s only large-scale rare earth mining and processing hub. Its flagship California mine ranks as the world’s second-largest rare earth deposit, supplemented by processing facilities in Fort Worth, Texas.
