About MP Materials Corp. / DE

MP Materials Corp. (NYSE: MP) is a U.S.-based industrial materials company focused on rare earths and the permanent-magnet supply chain. Headquartered in Las Vegas, Nevada, the company operates primarily in the United States and is building an integrated domestic platform that spans mining, processing, separation, metallization, and magnet manufacturing. Its core asset is the Mountain Pass complex in California, one of the most important rare earth deposits outside China and the foundation of MP Materials’ long-term industrial strategy. The company was founded in 2017, following the restart and modernization of Mountain Pass, with the goal of rebuilding a secure U.S. rare earth supply chain for defense, electric vehicles, electronics, and energy applications. MP Materials is organized around two operating segments. The Materials segment covers mining, processing, and the production of rare earth concentrate and refined rare earth products at Mountain Pass. The Magnetics segment centers on the Independence facility in Fort Worth, Texas, where the company produces rare earth metals, alloys, and precursor materials for magnets, with commercial-scale NdFeB permanent magnet production being rolled out progressively. This vertical integration is a key competitive advantage, because it reduces dependence on overseas suppliers and supports the re-shoring of strategic materials in the United States. From a competitive standpoint, MP Materials is one of the few integrated rare earth producers in North America. It benefits from strategic relevance, domestic industrial policy support, and exposure to structurally attractive end markets, but it also faces meaningful risks, including commodity price volatility, execution risk as it expands downstream capacity, and the capital intensity of scaling a full magnet supply chain. Its main products and services include rare earth concentrate, separated oxides, metals, alloys, and eventually permanent magnets for high-tech industrial applications. Recent milestones have strengthened the investment case. In 2025, MP Materials announced a $500 million partnership with Apple to supply recycled rare earth magnets manufactured in the United States, and it also unveiled a transformational public-private partnership with the U.S. Department of Defense to accelerate American magnet independence. In February 2026, the company selected Northlake, Texas, as the site for “10X,” a future large-scale rare earth magnet manufacturing campus. These developments reinforce MP Materials’ status as a strategically important U.S. materials company listed on the NYSE/NASDAQ market in the United States.
