This milestone is the result of years of compounding capabilities across the MP platform and marks an inflection point for our business and mission.” Third Quarter 2026 Consolidated Financial Highlights For the three months ended September 30, 2026 vs. 2025 (in thousands, except per share data, unaudited) 2026 2025 $ Change % Change Financial Measures: Revenue $ 147,655 $ 53,553 $ 94,102 176 % Price protection agreement income $ 8,109 $ — $ 8,109 N/M Net loss $ (20,710 ) $ (41,780 ) $ 21,070 50 % Adjusted EBITDA 2 $ 41,138 $ (12,570 ) $ 53,708 N/M Adjusted Net Income (Loss) 2 $ 8,768 $ (17,835 ) $ 26,603 N/M Diluted loss per common share $ (0.12 ) $ (0.24 ) $ 0.12 50 % Adjusted Diluted EPS 2 $ 0.04 $ (0.10 ) $ 0.14 N/M N/M = Not meaningful. 1 Includes sales volumes, revenue, and profits recognized in the Materials Segment on intercompany transactions with the Magnetics Segment. 2 See “Use of Non-GAAP Financial Measures” below for the definitions. See tables below for reconciliations of non-GAAP financial measures to their most directly comparable GAAP financial measures. Third Quarter 2026 Consolidated Review Consolidated revenue increased 176% year over year to $147.7 million, driven by higher sales of NdPr oxide and metal, as well as stronger market pricing. Revenue further benefited from a $31.6 million sale of SEG+ to a U.S. aerospace and defense customer in the quarter. The increase was partially offset by slightly lower revenue from magnetic precursor products due to the start-up of magnetics production at Independence. Adjusted EBITDA increased by $53.7 million year over year to $41.1 million, driven mainly by the changes in revenues discussed above, as well as the price protection agreement income (“PPA Income”) generated in the Materials Segment. These improvements were partially offset by higher cost of sales in the Materials Segment due to the significant growth in NdPr sales volumes, a $6.4 million reserve on certain non-core product inventories, and the sale of SEG+, as well as higher SG&A mainly driven by higher headcount to support our downstream expansion. Adjusted Net Income improved by $26.6 million year over year to $8.8 million, driven primarily by the higher Adjusted EBITDA discussed above. This improvement was partially offset by the amortization related to the price protection agreement upfront asset, with no comparable cost in the prior year period, and lower interest income due to changes in short-term investment balances. Net loss improved by $21.1 million year over year to $(20.7) million, primarily due to the factors driving the improvement in Adjusted Net Income (Loss) discussed above, and lower Advanced projects and development expenses, which in the prior year period included transaction costs associated with the DoW agreements and financing transactions. This improvement was partially offset by higher start-up costs from the ramp-up of start-up activities for initial magnet production, as well as higher stock-based compensation expense and an unfavorable change in the fair value of the derivative instrument associated with the 2030 Notes issued in December 2024. Diluted loss per common share and Adjusted Diluted EPS improved by $0.12 and $0.14 year over year, respectively, to $(0.12) and $0.04, respectively, in line with the change in Net loss and Adjusted Net Income (Loss) discussed above.

Use of Non-GAAP Financial Measures This press release references certain non-GAAP financial measures, including Adjusted EBITDA, Adjusted Net Income (Loss), and Adjusted Diluted EPS, which have not been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). MP Materials defines Adjusted EBITDA as GAAP net income or loss before interest expense, net; income tax expense or benefit; and depreciation, depletion and amortization; further adjusted to eliminate the impact of stock-based compensation expense; initial start-up costs; transaction-related and other costs; accretion of asset retirement and environmental obligations; gain or loss on disposals of long-lived assets; other income or loss; and other items that management does not consider representative of our underlying operations. MP Materials defines Adjusted Net Income (Loss) as GAAP net income or loss excluding the impact of stock-based compensation expense; initial start-up costs; transaction-related and other costs; gain or loss on disposals of long-lived assets; change in fair value of derivative instruments; and other items that management does not consider representative of our underlying operations; adjusted to give effect to the income tax impact of such adjustments. MP Materials defines Adjusted Diluted EPS as GAAP diluted earnings or loss per common share, excluding the per-share impact of each adjusting item described in the previous sentence (the numerator) divided by the adjusted diluted weighted-average shares outstanding (the denominator). MP Materials’ management uses Adjusted EBITDA, Adjusted Net Income (Loss), and Adjusted Diluted EPS to compare MP Materials’ performance to that of prior periods for trend analyses and for budgeting and planning purposes. MP Materials believes Adjusted EBITDA, Adjusted Net Income (Loss), and Adjusted Diluted EPS provide useful information to management and investors regarding certain financial and business trends relating to MP Materials’ financial condition and results of operations. MP Materials’ management believes that the use of Adjusted EBITDA, Adjusted Net Income (Loss), and Adjusted Diluted EPS provides an additional tool for investors to use in evaluating projected operating results and trends. MP Materials’ method of determining these non-GAAP measures may be different from other companies’ methods and, therefore, may not be comparable to those used by other companies and MP Materials does not recommend the sole use of these non-GAAP measures to assess its financial performance. Management does not consider non-GAAP measures in isolation or as an alternative or to be superior to financial measures determined in accordance with GAAP. The principal limitation of non-GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in MP Materials’ financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non-GAAP financial measures. In order to compensate for these limitations, management presents reconciliations of such non-GAAP financial measures to the most directly comparable GAAP financial measures. Segment Information The Company’s reportable segments, which are primarily based on the Company’s internal organizational structure and types of products, are its two operating segments—Materials and Magnetics. The Materials segment operates the Mountain Pass Rare Earth Mine and Processing Facility located near Mountain Pass, San Bernardino County, California, which produces refined rare earth products as well as rare earth concentrate and related products. The Magnetics segment includes (i) the rare earth metal, alloy and magnet manufacturing facility in Fort Worth, Texas (“Independence”), where the Company produces and sells magnetic precursor products and, beginning in December 2025, commenced manufacturing neodymium-iron-boron permanent magnets, and (ii) the 10X Facility. Segment Adjusted EBITDA is management’s primary segment measure of profit or loss required by GAAP in assessing segment performance and deciding how to allocate the Company’s resources. Segment Adjusted EBITDA is calculated as segment revenues and price protection agreement income less significant segment expenses, specifically, cost of sales (excluding depreciation, depletion and amortization and stock-based compensation expense) and selling, general and administrative expenses (excluding stock-based compensation expense), as well as certain other operating expenses (referred to as “other segment items”). Significant segment expenses and other segment items also exclude certain costs that are non-recurring, non-cash or are not related to the segments’ underlying business performance. Key Performance Indicators NdPr Production Volume for a given period is measured in MTs, the Company’s principal unit of sale for its NdPr separated products. This measure refers to the volume of finished and packaged NdPr oxide produced at Mountain Pass for a given period. NdPr Production Volume is a key indicator of the separating and finishing capacity and efficiency of the Company’s midstream operations. NdPr Sales Volume for a given period is measured in MTs and on an NdPr oxide-equivalent basis (as further discussed below). NdPr Sales Volume is a key measure of our ability to convert our production of separated NdPr products into revenue. A unit, or MT, is considered sold once the Materials segment recognizes revenue on its sale, whether sold as NdPr oxide or NdPr metal, as determined in accordance with GAAP. For these NdPr metal sales, the MTs sold and included in NdPr Sales Volume are calculated based on the volume of NdPr oxide used to produce such NdPr metal. In the first quarter of 2026, to better reflect current contractual production yields, we began to utilize an assumed material conversion ratio of 1.25, such that a sale of 100 MTs of NdPr metal would be included in this KPI as 125 MTs of NdPr oxide-equivalent. Prior to this update, we utilized an assumed material conversion ratio of 1.20. The prior period amounts have not been recast. Beginning with the fourth quarter of 2025, NdPr Sales Volume for the Materials segment includes intercompany sales made to the Magnetics segment. REO Production Volume for a given period is measured in MTs, the Company’s principal unit of sale for its concentrate product historically. This measure refers to the REO content contained in the rare earth concentrate we produce and includes volumes fed into downstream circuits for producing separated rare earth products, a portion of which is also included in our KPI, NdPr Production Volume. REO Production Volume is a key indicator of the mining and processing capacity and efficiency of the Company’s upstream operations.
