What Happened to MP Materials Corp.?

MP Materials Corp. (NYSE: MP) emerged as a publicly traded entity in 2020 through a SPAC merger, leveraging its ownership of the Mountain Pass mine in California, the only active rare earth mining and processing operation of its scale in the Western Hemisphere. Initially, the company primarily focused on extracting and processing rare earth concentrate, with a significant portion of its output historically sent to China for further separation. The stock experienced considerable interest due to its strategic position in the rare earth supply chain, a sector deemed critical for national security and advanced technologies.

A pivotal turning point for MP Materials and its stock performance occurred in July 2025, when the company announced a transformational public-private partnership with the U.S. Department of Defense (DoD). This comprehensive agreement aimed to accelerate U.S. rare earth magnet independence. The DoD committed to a $400 million investment in MP Materials' preferred convertible stock, provided a $150 million loan to expand heavy rare earth separation capabilities at Mountain Pass, and established a 10-year price floor of $110 per kilogram for MP's Neodymium-Praseodymium (NdPr) products. Furthermore, the DoD secured a 100% offtake commitment for 7,000 metric tons per year of expanded magnet manufacturing capacity from MP Materials' planned '10X' facility, effectively taking an approximate 15% stake in the company. This partnership significantly de-risked MP Materials' ambitious vertical integration strategy and provided a strong foundation for its downstream expansion.

Following this announcement, MP Materials' stock saw a substantial rally, reaching an all-time high closing price of $98.65 on October 14, 2025. The company's strategy shifted towards becoming a fully integrated 'mine-to-magnet' producer, with plans to invest over $1.25 billion in its 10X large-scale rare earth magnet manufacturing campus in Northlake, Texas, targeting an annual capacity of 10,000 metric tons of NdFeB magnets, with commissioning expected in 2028. MP Materials also secured long-term supply agreements with major companies like Apple for recycled rare-earth magnets and General Motors for finished magnets, with commercial sales to GM anticipated in the second half of 2026.

In its Q4 2025 earnings report, released on February 26, 2026, MP Materials reported revenue of $52.7 million, a 13.6% year-over-year decline, missing analyst estimates. However, diluted earnings per share (EPS) of $0.05 surpassed expectations. The decline in revenue was partially attributed to the cessation of rare earth concentrate sales to China starting in July 2025, a strategic move aligned with its vertical integration efforts. Adjusted EBITDA, however, saw a significant improvement to $39.2 million, largely driven by the Price Protection Agreement with the DoD. The company also reported doubling its NdPr oxide output to 2,599 metric tons in fiscal year 2025 and a 75% increase in NdPr oxide sales volumes.

As of March 2026, MP Materials continues to advance its expansion projects, including the commissioning of heavy rare earth separation capabilities at Mountain Pass by mid-2026. However, the stock experienced a notable dip of 8.7% on March 19, 2026, following investor concerns about fresh U.S. government financing for a domestic competitor, USA Rare Earth, and the substantial capital expenditure requirements for MP Materials' own projects. Despite this, analysts generally maintain a 'Buy' consensus rating, with a median price target of $76.0, forecasting significant earnings and revenue growth in the coming years, driven by the structural demand for rare earth magnets and the company's strategic position in securing a domestic supply chain. The company ended Q4 2025 with over $1.8 billion in cash, supporting its projected capital expenditures of $500-$600 million for 2026.
