NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1—DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

Description of Business: MP Materials Corp., including its subsidiaries (the “Company” or “MP Materials”), is the largest producer of rare earth materials in the Western Hemisphere. Headquartered in Las Vegas, Nevada, the Company owns and operates the Mountain Pass Rare Earth Mine and Processing Facility (“Mountain Pass”) located near Mountain Pass, San Bernardino County, California, the only rare earth mining and processing site of scale in North America. The Company is also developing a rare earth metal, alloy and magnet manufacturing facility in Fort Worth, Texas (the “Independence Facility”), where the Company produces and sells magnetic precursor products and anticipates manufacturing neodymium-iron-boron (“NdFeB”) permanent magnets by the end of 2025. The Company’s operations are organized intotwo reportable segments: Materials and Magnetics. See Note 20, “Segment Reporting,” for additional information.

The Company produces refined rare earth oxides and related products as well as rare earth concentrate products. The rare earth concentrate is principally sold pursuant to the Offtake Agreement to Shenghe (as such terms are defined in Note 19, “Related-Party Transactions”), a related party of the Company, that, in turn, typically sells that product to refiners in China. The Company also produces and generates revenue from the sale of separated rare earth products, including neodymium-praseodymium (“NdPr”) oxide. Additionally, the Company has a long-term agreement with General Motors Company (NYSE: GM) (“GM”) to supply U.S.-sourced and manufactured rare earth materials and finished magnets used in electric motors.

The cash flows and profitability of the Company’s operations are significantly affected by the market price of rare earth products, which are generally also impacted by taxes and tariffs. The prices of rare earth products are affected by numerous factors beyond the Company’s control. The products of the Company are sold globally, with a primary focus in the Asian market due to the refining, metallization, and magnet manufacturing capabilities of the region. See the“Concentration of Risk” section in Note 2, “Significant Accounting Policies,” for additional information. Rare earth products are critical inputs in hundreds of existing and emerging clean-tech applications including electric vehicles and wind turbines as well as robotics, drones, and defense applications.
