MP Materials Corp (NYSE: MP) secured a $400 million investment from the US Department of Defense in July 2025 — the largest single government commitment to a domestic rare earth company in American history — in a deal that repositions the MP Materials DoD relationship as the structural backbone of US rare earth magnet independence. The agreement locks in 7,000 metric tonnes per year of magnet offtake for ten years and requires MP to exit all sales to China.
Company Overview
MP Materials operates Mountain Pass in San Bernardino County, California — the only active rare earth mine and processing facility in the United States. The site was originally developed in 1952, passed through Molycorp’s bankruptcy in 2015, and was acquired and restarted by MP Materials, which has since expanded it into the world’s second-largest producer of rare earth oxides by volume.
The company’s strategy is vertical integration: mine, separate, alloy, and manufacture finished NdFeB permanent magnets in the United States, ending the structural dependence on Chinese processing that has defined Western rare earth supply chains for three decades.

MP Materials DoD — The $400 Million Partnership
The Department of Defense — now designated the Department of War — invested $400 million in MP Materials in July 2025 in exchange for convertible preferred equity and warrants representing approximately 15% of the company on an as-converted basis. The commercial terms are as significant as the capital: DoD committed to purchase 7,000 MT per year of NdFeB rare earth magnets over ten years, covering both defence and commercial end-uses.
As a condition of the agreement, MP Materials ceased all product sales to China, including concentrate shipments previously sent to Shenghe Resources — a Chinese state-adjacent company that had been processing Mountain Pass concentrate in China since MP’s restart. Those shipments stopped in Q3 2025. Shenghe retains a shareholding in MP Materials, which continues to present a governance complexity the company has not fully resolved publicly.
The MP Materials DoD deal is structurally different from conventional defence procurement or grant funding. The equity-plus-offtake structure gives DoD a direct commercial stake in MP’s success while guaranteeing the revenue base needed to justify the capital expenditure programme. For procurement professionals and investors tracking North American critical minerals supply chains, it establishes a template for how the US government may structure future strategic minerals partnerships.
Mountain Pass Operations
Mountain Pass produced 50,692 metric tonnes of rare earth oxides (REO) in FY 2025 — a record, up 12% year-on-year — representing approximately 11.5% of global output. NdPr oxide production reached 2,599 MT, also a record and roughly double the prior year, with 1,994 MT sold — up 75% year-on-year as the Stage 2 separation circuit ramped toward full capacity.
The deposit is predominantly light rare earth in composition: lanthanum and cerium account for the majority of output by mass, with NdPr at approximately 15%. Heavy rare earths — dysprosium (Dy) and terbium (Tb), both critical for high-performance magnets operating at elevated temperatures — are present in the deposit’s SEG+ fraction and have been stockpiled since late 2023. A dedicated heavy rare earth separation facility at Mountain Pass is targeting commissioning in mid-2026, with third-party feedstocks planned to supplement internal production.
Independence and the 10X Magnetics Facility
MP’s downstream manufacturing strategy centres on two Texas facilities. The Independence facility in Fort Worth produced the first NdFeB permanent magnets on commercial equipment in December 2025, with capacity currently at 1,000 MT per year expanding to 3,000 MT. Confirmed customers include General Motors, committed to 1,000 MT per year, and Apple, which made a $32 million progress payment referenced in Q4 2025 results under a materials supply agreement.
The larger commitment is 10X — a new 120-acre magnet manufacturing campus selected for Northlake, Texas. Planned capacity is 7,000 MT per year of NdFeB magnets, directly sized to fulfil the DoD offtake contract. Total investment is approximately $1.25 billion; a $200 million state incentive package has been secured. Groundbreaking is targeted for 2026. Combined with Independence at full capacity, MP’s total magnet manufacturing target is 10,000 MT per year — a scale that would make it the largest rare earth magnet producer outside China.
FY 2026 capital expenditure guidance is $500–600 million, covering the 10X facility, Independence expansion, heavy rare earth separations, and recycling infrastructure. The company held over $1.8 billion in cash at year-end 2025, providing runway for the programme without immediate equity dilution.
MP Materials in the Global Rare Earth Market
China mines over 60% of global rare earths and controls approximately 80% of processing and separation capacity. MP Materials is the only Western company currently operating at scale across both mining and separation, and the only one with a credible near-term path to domestic magnet manufacturing. For a broader view of how data centre and AI demand is reshaping technology metals supply chains, the structural pressure on rare earth supply is directly relevant.
NdPr oxide is distributed to Japan through a supply agreement with Sumitomo Corporation, and NdPr metal conversion is handled in part through a tolling agreement with Vietnam Rare-Earth Company, with South Korean customers also receiving oxide. The geographic spread of offtake reduces concentration risk beyond the US defence relationship, though the DoD contract represents the single largest committed revenue line in the business.
MP’s FY 2025 revenue was $275.5 million, up 35% year-on-year from $203.9 million. Net loss was $85.9 million — the company remains pre-profitability at the net income level, though Q4 2025 produced $39.2 million in adjusted EBITDA, the first profitable quarter on that metric. Analysts tracking the company treat the DoD offtake commencement timeline as the critical variable for the path to sustained profitability. NdPr prices remain below their 2022 peak, compressing per-tonne revenue relative to the investment phase.

Risks and Outlook
The principal risks are execution, price, and governance. The 10X facility and heavy rare earth separation commissioning are large, complex capital projects with no margin for significant delay if the DoD offtake timeline is to be met. NdPr prices at current levels constrain revenue per tonne relative to the cost of building a fully integrated Western supply chain. Shenghe Resources’ continuing shareholding in MP creates a governance complexity that the DoD agreement has not eliminated — it remains a live question for investors and policymakers focused on supply chain security.
The structural case is intact: the US has one operating rare earth mine, one company building the downstream manufacturing to match it, and a government now financially committed to both. How that execution unfolds through 2026 and 2027 — heavy REE commissioning, 10X groundbreaking, first DoD magnet deliveries — will determine whether the MP Materials DoD partnership becomes the model for allied-nation critical minerals strategy or a cautionary note on the difficulty of rebuilding supply chains from scratch.

What is the MP Materials DoD partnership?
The US Department of Defense invested $400 million in MP Materials in July 2025 in exchange for convertible preferred equity representing approximately 15% of the company. DoD simultaneously committed to purchase 7,000 metric tonnes per year of NdFeB rare earth magnets over ten years. The deal required MP Materials to cease all sales to China.
What does MP Materials produce?
MP Materials mines and processes rare earth oxides at Mountain Pass, California — the only active rare earth mine in the United States. Its primary commercial product is NdPr (neodymium-praseodymium) oxide, used in permanent magnets for electric vehicles, wind turbines, and defence applications. The company is expanding into finished NdFeB magnet manufacturing through its Texas facilities.
Where is the Mountain Pass rare earth mine located?

It is the only operating rare earth mine and separation facility in the United States, producing approximately 11.5% of global rare earth oxide output.
Does MP Materials still sell to China?
No. As a condition of the DoD partnership announced in July 2025, MP Materials ceased all product sales to China, including the concentrate shipments previously sent to Chinese state-adjacent company Shenghe Resources for processing in China. Shenghe retains a shareholding in MP Materials.
What is the 10X facility?
10X is a planned 120-acre rare earth magnet manufacturing campus in Northlake, Texas, targeting 7,000 MT per year of NdFeB magnet production — sized directly to fulfil the DoD offtake contract.
