MP Materials is a leading American rare earth materials company headquartered in Las Vegas, Nevada, and the owner and operator of the Mountain Pass mine in California—the only active rare earth mine and processing facility in the United States. Founded in 2017, MP Materials was established to revive the Mountain Pass site, which had previously been idle and on the brink of closure. The company’s mission is to restore the full rare earth supply chain in the U.S., ensuring domestic access to critical materials essential for advanced technologies. MP Materials specializes in producing Neodymium-Praseodymium (NdPr), a rare earth element vital for high-strength permanent magnets used in electric vehicles, robotics, wind turbines, drones, and defense applications. The company is unique in its fully integrated approach, controlling every stage of the supply chain from mining and processing to advanced metallization and magnet manufacturing. This vertical integration positions MP Materials as a key player in the global rare earth industry and a champion of American manufacturing renewal. A major achievement for MP Materials has been the successful reboot of the Mountain Pass mine, transforming it into a modern, efficient, and environmentally responsible operation. The company is listed on the New York Stock Exchange under the ticker “MP” and has attracted significant investment, including a notable deal with the U.S. Department of Defense in July 2025, which made the DoD its largest shareholder. MP Materials is recognized for its commitment to innovation, sustainability, and national security. Its work is crucial for reducing U.S. reliance on foreign rare earth sources and supporting the growth of clean energy and advanced technology sectors. With a strong focus on entrepreneurship, integrity, and safety, MP Materials continues to lead the reinvigoration of American industry and the global rare earth supply chain.
