MP Targets Mid-2026 for heavy rare earth commissioning with Dy/Tb production focus

Generated consolidated revenue of $53.6 million

Magnetics Segment continued to scale, generating $21.9 million in revenue and $9.5 million in Adjusted EBITDA

LAS VEGAS--(BUSINESS WIRE)-- MP Materials Corp. (NYSE: MP) (“MP Materials” or the “Company”), today announced financial and operational results for the three months ended September 30, 2025.

“MP Materials delivered another strong quarter, achieving record NdPr oxide production at Mountain Pass and record NdPr metal output at Independence,” said James Litinsky, Founder, Chairman, and CEO of MP Materials. “This performance underscores the momentum we are building at a pivotal time for our Company and Country. With key portions of our agreements with the Department of War commencing in the current quarter, we now have enhanced cash flow visibility to accelerate scaled magnet production in the United States—beginning with first commercial output from Independence by year-end.”

Heavy Rare Earth Production Update

MP plans to begin commissioning its new heavy rare earth separation facility at Mountain Pass in mid-2026. The facility is designed to process approximately 3,000 MT of feedstock per year and will initially prioritize production of dysprosium (Dy) and terbium (Tb). The Dy/Tb circuit will have a nameplate capacity of 200 MT per year and support MP’s planned production of 10,000 MT of high-performance NdFeB magnets per year.

Since late 2023, MP has been producing and stockpiling heavy rare earth concentrate (SEG+) at Mountain Pass. SEG+ contains medium rare earths samarium (Sm), europium (Eu), and gadolinium (Gd) and heavy rare earths Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y. In addition to processing its own SEG+ feedstock, MP’s heavy rare earth facility will process third-party feedstocks from emerging sources. MP is actively engaging emerging suppliers and plans to integrate several sources over time.

Following initial Dy and Tb production, MP plans to commence production of additional heavy rare earth products, starting with Sm, in line with its agreement with the Department of War.

Third Quarter 2025 Consolidated Review

To align with the terms of the recent agreements with the United States Department of War (the “DoW”), formerly known as the Department of Defense, and in further support of our domestic supply chain objectives, we ceased all sales of our products to China, which resulted in no revenue recognized from rare earth concentrate during the quarter, driving the 15% decline in consolidated revenue year over year to $53.6 million. The decline in revenue was partially offset by $21.9 million of magnetic precursor products sales with no comparable revenue in the prior year period, coupled with an $11.7 million increase in NdPr oxide and metal sales driven by higher NdPr Production Volume as a result of ramping production of separated products over the last twelve months.

Adjusted EBITDA declined by $1.4 million year over year to $(12.6) million, driven mainly by the decline in rare earth concentrate revenue, partially offset by the sales of magnetic precursor products, which drove a $13.1 million year over year improvement in the Magnetics Segment Adjusted EBITDA. Materials Segment Adjusted EBITDA decreased by $12.0 million year over year mainly due to the net decrease in revenue discussed above.

Adjusted Net Loss improved by $1.8 million year over year to $(17.8) million, driven by a higher income tax benefit along with higher interest income due to increased cash and short-term investment balances. The improvement in Adjusted Net Loss was partially offset by higher depreciation expense resulting from an increase in capital assets placed into service over the last year.

Net loss increased by $16.3 million year over year to $(41.8) million, primarily driven by the net decrease in revenue, along with $17.0 million in higher Advanced projects and development expenses, which included transaction costs associated with the DoW agreements and transaction costs incurred to secure financing.

Diluted loss per common share (“EPS”) increased by $0.08 year over year to a diluted loss per common share of $(0.24), in line with the change in Net loss discussed above. Adjusted Diluted EPS increased by $0.02 to $(0.10) in line with the improved Adjusted Net Loss discussed above.

Third Quarter 2025 Materials Segment Review

Materials Segment revenue decreased 50% to $31.6 million year over year, driven by the cessation of all REO sales to third parties in July 2025, which resulted in no revenue recognized from rare earth concentrate during the quarter. The decrease in revenue was partially offset by an $11.7 million increase in NdPr oxide and metal sales due to a 30% increase in NdPr Sales Volumes and a 26% increase in market prices. The increase in NdPr Sales Volumes was driven by the continued transition to production of NdPr oxide. REO Production Volumes decreased 4% year over year to 13,254 metric tons.

Materials Segment Adjusted EBITDA declined by $12.0 million year over year to $(14.5) million, primarily due to the net decrease in revenue discussed above. The Materials Segment cost of sales (“Segment COS”) decreased by $19.6 million, driven by the decrease in sales of rare earth concentrate, partially offset by the transition to sales of separated rare earth products, primarily NdPr oxide, which have higher per-unit production costs. Per-unit production costs of separated products are necessarily higher than those of rare earth concentrate due to the additional processing required. Separated product production costs on a per-unit basis are currently elevated given the temporary underutilization of the refining facilities as we ramp to normalized production levels.

(2)		Included in “Start-up costs” within our unaudited Condensed Consolidated Statements of Operations and excludes any applicable stock-based compensation, which is included in the “Stock-based compensation expense” line above. Primarily relates to certain costs incurred in connection with the commissioning and starting up of our initial magnet-making capabilities at Independence prior to the achievement of commercial production. These costs include labor of incremental employees hired in advance to work directly on such commissioning activities, training costs, costs of testing and commissioning the new circuits and processes, and other related costs. Given the nature and scale of the related costs and activities, management does not view these as normal, recurring operating expenses, but rather as non-recurring investments to initially develop our separations and magnet-making capabilities. Therefore, we believe it is useful and necessary for investors to understand our core operating performance in current and future periods by excluding the impact of these start-up costs. To the extent additional start-up costs are incurred in the future to expand our separations and magnet-making capabilities after initial achievement of commercial production (e.g., significantly expanding production capacity at an existing facility or building a new separations or magnet manufacturing facility), such costs would not be considered an adjustment for this non-GAAP financial measure.

(1)		Principally included in “Selling, general and administrative” within our unaudited Condensed Consolidated Statements of Operations.
(2)		Included in “Start-up costs” within our unaudited Condensed Consolidated Statements of Operations and excludes any applicable stock-based compensation, which is included in the “Stock-based compensation expense” line above. Primarily relates to certain costs incurred in connection with the commissioning and starting up of our initial magnet-making capabilities at Independence prior to the achievement of commercial production. These costs include labor of incremental employees hired in advance to work directly on such commissioning activities, training costs, costs of testing and commissioning the new circuits and processes, and other related costs. Given the nature and scale of the related costs and activities, management does not view these as normal, recurring operating expenses, but rather as non-recurring investments to initially develop our separations and magnet-making capabilities. Therefore, we believe it is useful and necessary for investors to understand our core operating performance in current and future periods by excluding the impact of these start-up costs. To the extent additional start-up costs are incurred in the future to expand our separations and magnet-making capabilities after initial achievement of commercial production (e.g., significantly expanding production capacity at an existing facility or building a new separations or magnet manufacturing facility), such costs would not be considered an adjustment for this non-GAAP financial measure.
(3)		Pertains to legal, consulting, and advisory services, and other costs associated with specific transactions, including litigation matters, potential acquisitions, mergers, or other investments. The three and nine months ended September 30, 2025, include $7.4 million of transaction costs incurred to secure financing, as well as $10.6 million and $12.4 million, respectively, of transaction costs incurred in association with the DoW transactions. For the three and nine months ended September 30, 2025, and for the nine months ended September 30, 2024, amounts are principally included in “Advanced projects and development” within our unaudited Condensed Consolidated Statements of Operations. For the three months ended September 30, 2024, amount is principally included in “Selling, general and administrative” within our unaudited Condensed Consolidated Statements of Operations.
(4)		Included in “Other operating costs and expenses (income), net” within our unaudited Condensed Consolidated Statements of Operations.
(5)		Pertains to the gain recognized on the repurchase of $480.0 million aggregate principal amount of our 2026 Notes in March 2024.
(6)		Included in “Other income, net” within our unaudited Condensed Consolidated Statements of Operations and pertains to the change in fair value of the redemption feature included in the portion of the 2030 Notes that were issued in December 2024.
(7)		Tax impact of adjustments is calculated using an adjusted effective tax rate, which excludes the impact of discrete tax costs and benefits, to each adjustment. The adjusted effective tax rates were 26.7%, 25.7%, 33.1% and 28.5% for the three and nine months ended September 30, 2025 and 2024, respectively.

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; gain or loss on early extinguishment of debt; 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; gain or loss on early extinguishment of debt; 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, using adjusted diluted weighted-average shares outstanding as the denominator, of stock-based compensation expense; initial start-up costs; transaction-related and other costs; gain or loss on disposals of long-lived assets; gain or loss on early extinguishment of debt; 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. In addition, when appropriate, we include an adjustment to reverse the impact of applying the if-converted method to our 2026 Notes if necessary to reconcile between GAAP diluted earnings or loss per common share and Adjusted Diluted EPS.

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. Prior period amounts have been recast to conform to this segment reporting structure, which was modified during the fourth quarter of 2024.

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 operates a rare earth metal, alloy and magnet manufacturing facility in Fort Worth, Texas (“Independence”), where the Company produces and sells magnetic precursor products and anticipates manufacturing NdFeB permanent magnets by the end of 2025.

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 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

REO Production Volume is measured in MTs, the Company’s principal unit of sale for its concentrate product. This measure refers to the REO content contained in the rare earth concentrate we produce and, beginning in the second quarter of 2023, includes volumes fed into downstream circuits for commissioning and starting up our separations facilities and 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.

Production Volume for a given period is measured in MTs, the Company’s principal unit of sale for its NdPr separated products. NdPr Production Volume 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.

Our NdPr Sales Volume for a given period is calculated in MTs and on an NdPr oxide-equivalent basis (as further discussed below). 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. We utilize an assumed material conversion ratio of 1.20, such that a sale of 100 MTs of NdPr metal would be included in this KPI as 120 MTs of NdPr oxide-equivalent. NdPr Sales Volume is a key measure of our ability to convert our production of separated NdPr products into revenue. In the future, NdPr Sales Volume for the Materials segment is expected to include sales made to the Magnetics segment.

NdPr Realized Price per kilogram (“KG”) for a given period is calculated as the quotient of: (i) our Materials segment NdPr oxide and metal sales, which are determined in accordance with GAAP, for a given period and (ii) our NdPr Sales Volume for the same period. NdPr Realized Price per KG is an important measure of the market price of our NdPr products. In the future, NdPr Realized Price per KG for the Materials segment is expected to include sales made to the Magnetics segment.
