MP Materials Corp. describes a rapidly expanding, vertically integrated rare earth business centered on its Mountain Pass mine and Independence magnet facility. The company now operates two segments: Materials, which produces NdPr and other rare earth oxides, and Magnetics, which has begun manufacturing NdFeB permanent magnets.
A transformational public‑private partnership with the U.S. Department of War underpins major growth projects, including expanding the Independence Facility, building a second 10X magnet plant, and adding heavy rare earth refining. The DoW guarantees at least $140 million of EBITDA at the 10X Facility and provides NdPr price floor protection at $110 per kg.
Long‑term supply agreements with General Motors and Apple position MP as a key U.S. supplier of magnets and recycled rare earth feedstock. The company highlights cost advantages, sustainability initiatives, and tight labor retention, but also details extensive regulatory, commodity price, execution, and covenant risks tied to its government partnership and debt.
MP Materials Corp. reported fourth-quarter and full-year 2025 results highlighting rapid growth in rare earth production and new downstream businesses.

For 2025, revenue rose 10% to $224.4 million, while net loss widened to $85.9 million and Adjusted EBITDA improved to $11.4 million from a $50.2 million loss. The company produced a record 2,599 metric tons of NdPr oxide, up 101%, and 50,692 metric tons of rare earth oxides in concentrate, up 12%. A new Magnetics segment delivered $66.9 million of magnetic precursor products revenue and positive segment Adjusted EBITDA. MP secured a $200 million incentive package for a new 10X magnetics facility in Texas, entered a “transformational” public‑private partnership with the Department of War, and signed long-term magnet and recycling agreements, including with Apple, while ending the year with $1.83 billion in cash, cash equivalents and short‑term investments.
