MP Materials operates a rare earth supply chain built around Mountain Pass in California and a downstream Magnetics platform in Texas. The company’s stated plan follows a three-stage buildout from mining and concentrate production to separated oxides and then to metal, alloy, and NdFeB permanent magnets.
How MP Materials makes money
MP reports two operating segments: Materials and Magnetics. The Materials segment runs Mountain Pass and generates revenue primarily from NdPr oxide and NdPr metal, with customers mainly in Japan, South Korea, and broader Asia. The Magnetics segment operates the Independence facility in Fort Worth, Texas, producing magnetic precursor products and starting NdFeB magnet manufacturing in December 2025.
Core activities
- Mining and concentrating (Mountain Pass): Open-pit mining and beneficiation produce rare earth concentrate, with onsite infrastructure that supports large-scale operations.
- Separation and product finishing (Mountain Pass): MP began producing separated rare earth products in 2023, with NdPr oxide as the key value driver. The site also produces other separated products such as cerium and lanthanum, plus a mixed heavy rare earth product (SEG+).
- Shift away from China sales: MP ceased all sales of its products to China in July 2025 and began stockpiling concentrate that is not sold or further processed into separated products.
- Metal, alloy, and magnets (Independence in Texas): The Texas plant converts Mountain Pass NdPr oxide into downstream products. MP’s filings state the first sales of magnetic precursor products, including NdPr metal, were made to General Motors and began in Q1 2025.
- Scaling NdPr and magnets: In 2025, MP produced 2,599 metric tons of NdPr oxide and sold 1,994 metric tons, alongside its first NdFeB magnets on commercial equipment at Independence.
A key earnings stabilizer is a Price Protection Agreement that started on Oct 1, 2025. MP describes it as a $110 per kg price floor for NdPr products for ten years, with cash payments tied to benchmark pricing for qualifying sold or stockpiled NdPr output.
Market position and competitive context
MP positions itself as the only rare earth mining and processing site of scale in North America, anchored by Mountain Pass and now paired with a U.S. downstream magnet platform. In its 10-K, MP highlights that rare earth mining, processing, and magnet manufacturing remain dominated by Chinese competitors. The filing also notes continued consolidation into two major rare earth groups in China, with control over quotas for concentrate production and refining, plus a dominant position in NdFeB magnets through vertically integrated infrastructure.
MP’s differentiation for investors comes from three levers:
- Asset scale and integration at Mountain Pass: A single U.S. site that covers mining, milling, separation, and finishing supports higher-value separated products versus concentrate-only models.
- Downstream expansion into magnets: Independence adds metal, alloy, precursor products, and NdFeB magnets, tying MP closer to OEM supply chains and higher value per ton of NdPr.
- Policy and customer pull for U.S. supply chains: MP cites a public-private partnership tied to the price floor and a long-term government offtake framework, plus a long-term agreement to supply Apple with magnets made from materials recycled at Mountain Pass.
For the next scale step, MP selected Northlake, Texas for its planned 10X magnet manufacturing campus, backed by a $1.25 billion-plus company investment, a $200 million incentive package, and a 10-year Pentagon offtake commitment cited by the company.
