MP Materials Corp.
MP Materials Corp., together with its subsidiaries, produces rare earth materials in the Western Hemisphere. It operates in two segments, Materials and Magnetics. The Materials segment owns and operates the Mountain Pass Rare Earth Mine and Processing facility located near Mountain Pass, San Bernardino County, California. The Magnetics segment produces magnetic precursor products, including NdPr metal; and manufactures NdFeB permanent magnets. MP Materials Corp. was founded in 2017 and is headquartered in Las Vegas, Nevada.
What does it do?
MP Materials owns and operates the only large-scale rare earth mine in the Western Hemisphere, located at Mountain Pass in California's Mojave Desert. Rare earths are a group of metals with names like neodymium and praseodymium that most people have never heard of — but they're inside almost every electric vehicle motor, wind turbine, and smartphone speaker on the planet. Think of MP as the company trying to rebuild America's rare earth supply chain from scratch, since China currently dominates about 90% of global production. More recently, MP has started turning those raw materials into finished magnets, the actual components that go inside EV motors.
The U.S. government has identified rare earths as a critical national security material, and there's strong political will across both parties to reduce dependence on China for them. MP is essentially the only game in town for domestic rare earth production, which puts it at the center of the broader push to onshore critical supply chains for defense, EVs, and clean energy. With U.S.-China trade tensions remaining elevated, the strategic importance of what MP does has rarely been higher.
How does it make money?
MP makes money in two ways. First, its Materials segment mines and processes rare earth ore at Mountain Pass, selling a refined concentrate — mostly a compound called NdPr oxide — to customers, primarily in Asia. In its latest full year, this generated roughly $200 million in revenue, though weak rare earth prices pushed the business to an overall net loss of about $100 million. Second, its newer Magnetics segment is building out manufacturing to make finished neodymium-iron-boron (NdFeB) permanent magnets, the kind that go directly into EV motors, with General Motors as a key early customer under a long-term supply agreement.
Why do investors care?
The core growth story is vertical integration — MP wants to control the entire chain from digging ore out of the ground to delivering finished magnets to automakers, which would give it much stronger pricing power and fatter profit margins than just selling raw materials. The company also benefits from U.S. government support through grants and the Defense Production Act, which helps fund its magnet manufacturing buildout. For the thesis to work, rare earth prices need to recover from their current cyclical lows, the GM magnet supply deal needs to scale up, and MP needs to execute on converting its factory into a profitable operation. If all three happen, the company's revenue and profit picture could look dramatically different in three to five years.
