MP Materials Corp. / DE
MP Materials Corp. owns and operates the Mountain Pass rare earth mine and processing complex in California and the Independence metal, alloy and magnet facility in Texas. The company produces separated rare earth products such as NdPr oxide and metal, and is building downstream magnet manufacturing capabilities to supply industrial and automotive customers in the U.S. and Asia.

Business
Share of revenueMining and beneficiation output from Mountain Pass, historically sold as concentrate and now increasingly retained for further processing.
Refined NdPr oxide and NdPr metal produced at Mountain Pass and sold to industrial customers and distributors.
Metal and alloy products from Independence used as inputs for magnet manufacturing and sold under long-term supply agreements.
NdFeB magnet production from the Independence facility, which began in late 2025 and is being scaled for end users.
Smaller product lines including lanthanum carbonate and cerium chloride, plus related processing outputs.
Customers
MP Materials sells upstream and midstream rare earth products to distributors and industrial customers in Asia, while its downstream magnetics business serves U.S. OEMs and strategic partners. Customer demand is tied to electrification, defense, robotics, renewable energy and other applications that require high-performance magnets and rare earth inputs.
Buy NdPr oxide and NdPr metal for use in magnet supply chains and other industrial applications; this is a core revenue base.
Buy magnetic precursor products and future magnets to secure domestic supply for electric drive and other vehicle systems.
Buy or co-develop magnet supply and recycling capabilities to support supply-chain security and localization.
Purchase rare earth products for onward sale into end markets, especially in Asia.
Potential customers for scaled NdFeB magnet output as Independence ramps production.
Strategy
MP Materials is moving from a concentrate exporter to a vertically integrated rare earth and magnet producer. The strategy centers on scaling separated products, building domestic magnet manufacturing, and reducing dependence on China-linked sales channels.
Higher-value NdPr oxide and metal should replace lower-value concentrate sales and improve strategic control of output.
Downstream magnet production captures more value and reduces reliance on external magnet supply chains.
Recycling and heavy rare earth projects can broaden feedstock access and strengthen long-term supply security.
Exiting China sales lowers geopolitical dependence but forces a faster transition to alternative customers and products.
Geography
Operations are concentrated in the United States, with Mountain Pass in California and Independence in Texas. Revenue has historically been exposed to Asia, especially Japan, South Korea and China, but the company ceased all sales to China in July 2025 and is shifting toward U.S. and allied-market customers.
Risks
The business is exposed to volatile rare earth pricing, customer concentration during the transition away from concentrate sales, and execution risk in scaling complex processing and magnet operations. It also faces geopolitical and trade-policy risk, since tariffs and China-related actions have already disrupted sales patterns and can affect demand, supply chains and working capital.
- Customer concentration and transition riskImpact: HighLikelihood: High
The company historically relied on a single China distributor and is still rebuilding its customer base after ceasing China sales.
Exposure: Materials segment
- Geopolitical and trade-policy disruptionImpact: HighLikelihood: High
Tariffs and policy changes between the U.S. and China have already materially affected the business and may continue to do so.
Exposure - Execution risk on downstream buildoutImpact: HighLikelihood: High
The company must scale separation, magnet manufacturing and recycling on aggressive timelines to realize its strategy.
Exposure - Rare earth and magnet material price volatilityImpact: HighLikelihood: Medium
Revenue depends on commodity-linked pricing for concentrate, NdPr oxide and metal, so market swings directly affect results.
Exposure - Capital intensity and funding needsImpact: MediumLikelihood: High
The transition to a fully integrated magnetics producer requires substantial capex and working capital before full payback.
Exposure: 2025-2026 capex and inventory build
Accounting
Judgemental itemsSales of concentrate, separated products and precursor products have different contract terms and pricing adjustments.
Impact: Can shift quarterly revenue timing and comparability
Unsold concentrate is being stockpiled for future use or processing, affecting inventory balances and cost absorption.
Impact: May influence gross margin and working capital
Mountain Pass and Independence expansion costs are substantial and will be capitalized before depreciation begins.
Impact: Affects PP&E, depreciation and free cash flow
Construction-related government proceeds are netted against additions to property, plant and equipment in free cash flow disclosure.
Impact: Can make capex and cash burn appear lower than gross spend
If ramp-up or market conditions weaken, large mining and processing assets could require impairment testing.
Impact: Could create non-cash charges
