MP Materials vs. USA Rare Earth: Divergent Paths in Domestic Supply
MP Materials generates revenue from existing magnet production, while USA Rare Earth targets high-value heavy rare earths with operations set for 2028.
MP Materials (MP) generates revenue from its operational Mountain Pass mine and Fort Worth magnet facility, serving established customers like Apple and General Motors. In contrast, USA Rare Earth (USAR) is a pre-revenue entity that secured 100% ownership of the Round Top deposit in Texas, targeting commercial operations in late 2028. The two firms represent distinct approaches to reducing U.S. reliance on Chinese rare-earth supplies, a dependency that exceeds 90% of the global market.
The strategic difference lies in element focus. MP Materials specializes in light rare-earth elements (LREE) such as neodymium and praseodymium, which are abundant but lower in value. USA Rare Earth targets heavy rare-earth elements (HREE) like dysprosium and terbium. These HREEs constitute only 20% of global volume but over 90% of the market value, a segment where China processes nearly 100% of supply. This makes USAR’s potential upside higher, but its execution risk significantly greater.
Operational maturity creates a valuation gap
MP Materials has an active business model, with its Mountain Pass mine supplying elements and its Fort Worth facility producing magnets. Construction has begun on its new "10X" facility in Northlake, Texas, a cornerstone of its Department of Defense partnership. This tangible progress supports a forward price-to-earnings ratio of 65.8 for 2027, declining to 23.0 by 2030.
USA Rare Earth entered magnet production in the second quarter of this year, with first sales expected by year-end. However, its mining component remains in the development phase. Analysts project no earnings for 2027, with a forward P/E of 48.4 in 2028 and 7.1 in 2030. This lower valuation reflects the uncertainty of executing a mine-to-magnet strategy for complex HREEs, a process that is technically demanding and harder to source than LREEs.
Strategic importance drives investment risk
Both companies have received U.S. government backing to secure national security interests in rare-earth magnets. However, the risk profiles differ. MP Materials offers a more immediate path to domestic supply stability through its existing infrastructure. USA Rare Earth offers a higher-risk, higher-return proposition by addressing the most critical and value-dense segment of the rare-earth market. Investors must weigh the certainty of MP’s current revenue against the speculative potential of USAR’s future dominance in HREEs.
