MP Materials (NYSE: MP) had a strong 2025, with shares up 224% before a market sell-off. The stock has gained 10.5% this year, but must navigate challenges for continued success. The company operates the Mountain Pass mine in California and a facility in Texas, crucial for rare-earth magnets used in tech and defense.

In July 2025, the Department of Defense invested $400 million in MP, becoming the largest shareholder and forming a partnership. The DoD will purchase 100% of magnets from MP’s U.S. factory for 10 years, guaranteeing a price floor of $110 per kilogram for its product. This news boosted MP stock over 100% in July.

MP faces risks despite the DoD agreement, such as execution challenges for its next facility. The stock trades at a premium valuation, at 43 times sales, posing a potential hurdle for investors. The company’s profitability hinges on continued government support, subject to congressional approval.

Consider MP as a long-term investment, but be prepared for volatility. If you’re uneasy with the stock’s valuation or potential risks, it might be best to wait. The Motley Fool Stock Advisor team didn’t list MP among their top 10 stocks, emphasizing the importance of thorough research before investing in the company.
