NOTE 11—COMMITMENTS AND CONTINGENCIES

Litigation: The Company may become party to lawsuits, administrative proceedings, and government investigations, including environmental, regulatory, construction, and other matters, in the ordinary course of business. Large, and sometimes unspecified, damages or penalties may be sought in some matters, and certain matters may require years to resolve. The Company is not aware of any pending or threatened litigation that it believes would have a material adverse effect on its unaudited Condensed Consolidated Financial Statements.

On April 17, 2026, a binding arbitration concluded with an award to a general contractor for a construction project totaling $45.3 million, consisting of $36.5 million for the associated claims (of which, $30.5 million was previously estimated and accrued as of December 31, 2025), and $8.8 million in interest. The claims component of $36.5 million pertained directly to the cost of the constructed assets and was recorded as an adjustment to “Property, plant and equipment, net” within the Company’s unaudited Condensed Consolidated Balance Sheets. The interest component of $8.8 million was recognized in “Other operating costs and expenses (income), net” within the Company’s unaudited Condensed Consolidated Statements of Operations. The Company paid the $45.3 million award amount during the three months ended June 30, 2026.

NOTE 12—REDEEMABLE PREFERRED STOCK

In July 2025, the Company issued 400,000 shares of newly designated Series A Cumulative Perpetual Convertible Preferred Stock (the “Series A Preferred Stock”) with a stated value of $1,000 per share (the “Stated Value”) to the DoW for cash consideration of $400.0 million. At the election of the DoW, the Series A Preferred Stock is convertible at any time into 13,320,013 shares of the Company’s common stock at an initial conversion price of $30.03 per share, subject to customary anti-dilution adjustments.

The Company’s Series A Preferred Stock is classified as redeemable preferred stock (i.e., temporary equity) outside of stockholders’ equity within the Company’s unaudited Condensed Consolidated Balance Sheets due to redemption rights for a deemed liquidation event that, in certain circumstances, is not solely within the Company’s control. The purpose of this classification is to convey that such a security may not be permanently part of equity and could result in a demand for cash, securities or other assets of the entity in the future.

In the event of a voluntary or involuntary liquidation (e.g., a deemed liquidation event), holders of the Series A Preferred Stock will be entitled to a distribution before any distribution to the holders of the Company’s common stock. The liquidation preference payable in cash or other assets equals the greater of (i) the sum of the Stated Value, certain paid-in-kind dividends as defined in the stock purchase agreement, and accrued and unpaid dividends (the “Liquidation Floor”) and (ii) the amount the holders of the Series A Preferred Stock would have received had all the Series A Preferred Stock been converted into common stock at the then-current conversion price immediately prior to such liquidation event. As of June 30, 2026, and December 31, 2025, the aggregate minimum liquidation preference (i.e., the Liquidation Floor) was $428.1 million and $413.5 million, respectively. The Company did not adjust the carrying amount of the Series A Preferred Stock to the current redemption value as a deemed liquidation event was not probable as of June 30, 2026. Subsequent adjustments to increase or decrease the carrying amount to the ultimate redemption value will be made only if a deemed liquidation event (i) has occurred or (ii) becomes probable of occurring in the future.

Total revenue$108,490$57,393$199,139$118,203

(1)Represents the elimination of intersegment revenues associated with NdPr oxide sales made by the Materials segment to the Magnetics segment.

NdPr oxide and metal revenue was primarily generated from sales made under the Company’s distribution agreement with Sumitomo Corporation of Americas as well as an offtake agreement with a leading U.S. technology and industrial company entered into during the first quarter of 2026.

Rare earth concentrate revenue was primarily generated from sales under the Shenghe Offtake Agreement (as defined in Note 19, “Related-Party Transactions”).

Magnetic precursor products revenue commenced in the first quarter of 2025 and was generated from sales of NdPr metal produced at the Independence Facility under the long-term supply agreement with GM.

Bill-and-Hold Arrangements: During the three and six months ended June 30, 2026, the Company recognized revenue under bill-and-hold arrangements of $51.3 million and $94.6 million, respectively, as compared to $19.9 million and $25.1 million for the three and six months ended June 30, 2025, respectively, under which control of the product transfers to the customer, but the product remains in the custody of the Company. For sales at the Materials segment, the performance obligation is satisfied at the point in time the finished product is delivered to a third party’s storage warehouse. For sales at the Magnetics segment, the performance obligation is satisfied at the point in time the finished product is packaged, segregated and ready for shipment to the customer.

Contract Balances: Contract liabilities, commonly referred to as deferred revenue, represent the Company’s obligation to transfer goods or services to a customer for which the Company has received consideration in advance of such transfer. Deferred revenue decreases as revenue is recognized from the satisfaction of the related performance obligations.

The following table summarizes the Company’s deferred revenue activity:

For the six months ended June 30,
(in thousands)20262025
Beginning balance(1)$158,190$100,000
Additions to deferred revenue(2)5,81050,000
Revenue recognized during the period(3)(37,592)(25,052)
Ending balance(1)$126,408$124,948
(1) Contract liabilities are included as current and non-current deferred revenue in the Company’s unaudited Condensed Consolidated Balance Sheets based on the Company’s expectation of when the performance obligations will be satisfied.
(2) For the six months ended June 30, 2026, the amount related to reimbursable costs from the DoW under the DoW Offtake Agreement (see Note 9, “Operating Leases,” for details) as well as a significant financing component associated with the Apple long-term supply agreement discussed below. For the six months ended June 30, 2025, the amount related to the final prepayment for magnetic precursor products under the long-term agreement with GM.
(3) All the revenue recognized during the period was included in the beginning deferred revenue balance. For the three months ended June 30, 2026, and 2025, the Company recognized $16.5 million and $19.9 million, respectively, of revenue that was included in the deferred revenue balance at the beginning of the period.

As of June 30, 2026, the Company classified the full amount of the remaining prepayment from GM of $45.5 million as current deferred revenue within its unaudited Condensed Consolidated Balance Sheets based on the Company’s expectation that the related performance obligations will be satisfied within one year after this date. The Company’s estimate of when the performance obligations will be satisfied and revenue will be recognized is dependent upon various operational decisions that could impact the production levels of NdPr metal at the Independence Facility.

In July 2025, the Company entered into a definitive, long-term supply agreement with Apple Inc. (“Apple”) for the development, manufacture, and supply of magnets from the Company’s Independence Facility, as well as the development and installation of scaled recycling capabilities at Mountain Pass to produce the contained rare earths from post-industrial and post-consumer recycled rare earth feedstocks. In connection with the agreement, and subject to achieving specified milestones, Apple agreed to make prepayments in the aggregate amount of $200.0 million for the purchase of magnets from the Company.

As of June 30, 2026, the Company had received cumulative prepayments from Apple of $72.0 million and had not yet recognized any of this amount as revenue under this arrangement. As of June 30, 2026, the Company classified the $72.0 million as non-current deferred revenue within its unaudited Condensed Consolidated Balance Sheets based on the Company’s expected satisfaction of the associated performance obligations beginning no earlier than the latter half of 2027. Due to the extended timing difference between when Apple makes a prepayment for magnets and when the Company expects to transfer control of those magnets to Apple, the Company identified a significant financing component. The significant financing component is accreted to interest expense using the Company’s incremental borrowing rate over the period in which the prepayments are outstanding with an accrual to increase deferred revenue.

NOTE 15—GOVERNMENT GRANTS

Asset-Based Grants: In February 2022, the Company was awarded a $35.0 million contract by the DoW Office of Industrial Base Analysis and Sustainment program to design and build a facility to process HREE at Mountain Pass (the “HREE Facility”) (the “HREE Production Project Agreement”). The funds received pursuant to the HREE Production Project Agreement reduce the carrying amount of the fixed assets associated with the HREE Facility. During the six months ended June 30, 2026 and 2025, the Company recorded HREE Facility grant amounts of $5.0 million and $12.2 million, respectively.

Income-Based Grants: In August 2022, the U.S. government enacted the Inflation Reduction Act of 2022, which, among other things, promotes clean energy adoption by providing several tax incentives for the domestic production and sale of eligible components. Specifically, the 45X Credit provides a credit equal to 10% of eligible “production costs incurred” with respect to the production and sale of critical minerals, including NdPr oxide.

As of June 30, 2026, and December 31, 2025, the government grant receivable and the deferred government grant balances within the Company’s unaudited Condensed Consolidated Balance Sheets pertained to the 45X Credit.

The current and non-current portions of the government grant receivable are included in “Other receivables” and “Other non-current assets,” respectively, within the Company’s unaudited Condensed Consolidated Balance Sheets (see also Note 13, “Supplemental Balance Sheet Information”). The non-current portion of the government grant receivable balance was $23.4 million andzero as of June 30, 2026 and December 31, 2025, respectively. During the six months ended June 30, 2026, the Company received $19.0 million related to the 45X Credit claimed on its 2024 federal tax return. The current portions of deferred government grants, which are included in “Other current liabilities,” were not material.

The benefits (reduction of expenses) recognized in the Company’s unaudited Condensed Consolidated Statements of Operations pertaining to the 45X Credit were recorded as follows:

NOTE 16—STOCKHOLDERS' EQUITY AND STOCK-BASED COMPENSATION

Warrant

On July 10, 2025, the Company issued a warrant (the “Warrant”) to the DoW, exercisable at any time, in whole or in part, in cash or in net share settlement at the DoW’s option, for a period often years prior to its expiration on July 10, 2035, for up to 11,201,659 shares of the Company’s common stock, at an initial exercise price of $30.03 per share. The strike price of $30.03 is subject to customary anti-dilution adjustments. As of June 30, 2026, no shares of common stock had been issued pursuant to the exercise of the Warrant.

Stock-Based Compensation

2020 Incentive Plan: In November 2020, the Company’s stockholders approved the MP Materials Corp. 2020 Stock Incentive Plan (the “2020 Incentive Plan”), which permits the Company to issue stock options (incentive and/or non-qualified); stock appreciation rights (“SARs”); restricted stock, restricted stock units (“RSUs”) and other stock awards (collectively, the “Stock Awards”); and performance awards, which vest contingent upon the attainment of market- and/or performance-based goals. In November 2025, the Board of Directors approved and authorized annual increases to the shares of common stock available for issuance under the 2020 Incentive Plan equal to 2% of the Company’s outstanding common stock as of December 31 st of the immediately preceding year, with the first increase effective January 1, 2026, and continuing annually through the year ending December 31, 2030. As of June 30, 2026, the Company had not issued any stock options or SARs and there were 7,392,043 shares available for future grants under the 2020 Incentive Plan.

Market-Based PSUs: In March 2026, pursuant to the 2020 Incentive Plan, the Compensation Committee of the Company’s Board of Directors adopted a performance share plan (the “2026 Performance Share Plan”). Pursuant to the 2026 Performance Share Plan, during the six months ended June 30, 2026, the Company granted 114,224 market-based performance stock units (“PSUs”) at target. The market-based PSUs have the potential to be earned at between 0% and 200% of the number of awards granted depending on the level of growth of the Company’s total shareholder return (“TSR”) as compared to the TSR of the S&P 500 Index over three separate performance periods of one, two, and three years. The market-based PSUs will cliff vest after a requisite service period of approximately three years, assuming the market-based TSR goals are achieved. The fair value of the market-based PSUs was determined using a Monte Carlo simulation technique.

NOTE 17—FAIR VALUE MEASUREMENTS

ASC Topic 820, “Fair Value Measurement,” establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

Level 1:Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
Level 2:Quoted prices in markets that are not active, quoted prices for similar assets or liabilities in active markets, quoted prices or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability and model-based valuation techniques (e.g., the Black-Scholes model) for which all significant inputs are observable in active markets;
Level 3:Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity).

The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of assets and liabilities and their placement within the fair value hierarchy. The following methods and assumptions are used to estimate the fair value of each class of financial instruments for which it is practicable to estimate. The fair value of the Company’s accounts receivable, accounts payable, and accrued liabilities approximates their respective carrying amounts because of the immediate or short-term maturity of these financial instruments.

Cash, Cash Equivalents and Restricted Cash

The fair value of the Company’s cash, cash equivalents and restricted cash is classified within Level 1 of the fair value hierarchy. The carrying amounts reported in the unaudited Condensed Consolidated Balance Sheets approximate the fair value of cash, cash equivalents and restricted cash due to the short-term nature of these assets.

Short-term Investments

The fair value of the Company’s short-term investments, which are classified as available-for-sale securities, is estimated based on quoted prices in active markets and is classified as a Level 1 measurement.

Derivative Instrument

The Company’s derivative instrument pertains to the redemption feature included in the portion of the 2030 Notes that were issued in December 2024. This instrument’s fair value is measured using a binomial lattice model, which utilizes observable inputs (e.g., the Company’s stock price) and unobservable inputs (e.g., the expected volatility and instrument specific discount rate) that cause the valuation measurements to be classified as Level 3. The significant unobservable inputs used in the determination of the fair value of instruments classified as Level 3 have an inherent measurement uncertainty that, if changed, could result in higher or lower fair value measurements of the derivative instrument as of the reporting date. The following assumptions were used within the model:

Valuation Assumptions:June 30, 2026December 31, 2025
Expected volatility76.2%79.6%
Risk-free interest rate4.2%3.7%
Discount rate8.2%7.7%
Dividend yield—%—%
Term to maturity3.7 years4.2 years
Stock price$56.01$50.52

Convertible Notes

The fair value of the Company’s Convertible Notes is estimated based on quoted prices in active markets and is classified as a Level 1 measurement.

Samarium Project Loan

The fair value of the Company’s Samarium Project Loan is based on inputs that are directly observable for substantially the full term of the liability and is classified as a Level 2 measurement. Model-based valuation techniques for which all significant inputs are observable in active markets were used to calculate the fair value of this liability.

Equipment Notes

The fair value of the Company’s equipment notes is based on inputs that are directly observable for substantially the full term of the liability and is classified as a Level 2 measurement. Model-based valuation techniques for which all significant inputs are observable in active markets were used to calculate the fair values for these liabilities.

The Company’s financial instrument assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The carrying amounts and estimated fair values by input level of the Company’s financial instruments were as follows:

(1)Thegains (losses) are included in “Other income, net” within the Company’s unaudited Condensed Consolidated Statements of Operations.

NOTE 18—LOSS PER SHARE

Net income or loss attributable to common stock is computed using the two-class method when shares are issued that meet the definition of participating securities. The Company’s Series A Preferred Stock is a participating security because these shares contractually entitle their holders to potentially participate in certain dividends, as such payments are defined in the stock purchase agreement, but do not contractually require their holders to participate in the Company’s losses.

The two-class method is an earnings allocation formula that requires undistributed earnings for the period to be allocated between common stock and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed. During the periods when there is a net loss, no amounts of undistributed losses are allocated to the Company’s participating securities.

Basic earnings or loss per common share is computed by dividing net income or loss attributable to common stock by the weighted-average number of common shares outstanding during the period.

Diluted earnings or loss per common share is computed by dividing net income or loss attributable to common stock (the numerator) by the weighted-average number of common shares outstanding during the period (the denominator) using the treasury stock method, the if-converted method, or the two-class method, as applicable. The numerator is adjusted for the effects of changes in income available to common stock that arise from the assumed conversion of dilutive convertible securities. The denominator is adjusted for the effects of dilutive potential common shares outstanding.

For the three and six months ended June 30, 2026, and 2025, the weighted-average common shares outstanding used in the calculation of basic loss per common share were the same as the weighted-average common shares outstanding used in the calculation of diluted loss per common share because the Company was in a loss position for both periods presented.

The following table presents unweighted potentially dilutive shares that were not included in the computation of diluted loss per common share because to do so would have been anti-dilutive:

In connection with the issuance of the 2030 Notes in March 2024, the Company entered into the Capped Call Options, which were not included for purposes of calculating the number of diluted shares outstanding, as their effect would have been anti-dilutive. The Company has not exercised any of the Capped Call Options as of June 30, 2026.

NOTE 19—RELATED-PARTY TRANSACTIONS

Shenghe Offtake Agreement: In 2024, the Company entered into an offtake agreement with Shenghe Resources (Singapore) International Trading Pte. Ltd. (“Shenghe”), a majority-owned subsidiary of Leshan Shenghe Rare Earth Co., Ltd. whose ultimate parent is Shenghe Resources Holding Co., Ltd., a leading global rare earth company listed on the Shanghai Stock Exchange (the “Shenghe Offtake Agreement”), that replaced and extended the then-existing offtake agreement with Shenghe.

Pursuant to the Shenghe Offtake Agreement, and subject to certain exclusions, Shenghe was obligated to purchase on a “take or pay” basis the rare earth concentrate produced by the Company as the exclusive distributor in China, with certain exceptions for the Company’s direct sales globally. In addition, at the discretion of the Company, Shenghe was required to purchase on a “take or pay” basis certain non-concentrate rare earth products, although the Company may have sold all non-concentrate rare earth products in its sole discretion to customers or end users in any jurisdiction.

In July 2025, to align with the terms of the DoW Transaction Agreements and in further support of its domestic supply chain objectives, the Company ceased all sales of its products to customers in China and did not extend the term of the Shenghe Offtake Agreement when it expired in January 2026.

Starting in the fourth quarter of 2025, Shenghe was no longer considered a related party of the Company.

Revenue and Cost of Sales: For the three and six months ended June 30, 2025, during the period when Shenghe was considered a related party, the Company recognized $11.9 million and $42.0 million, respectively, of rare earth concentrate revenue, $0.5 million and $9.3 million, respectively, of NdPr oxide and metal revenue and incurred $8.6 million and $31.4 million, respectively, of associated Cost of sales (excluding depreciation, depletion and amortization).

Purchases of Materials and Supplies: For the three and six months ended June 30, 2025, during the period when Shenghe was considered a related party, the Company purchased from Shenghe in the ordinary course of business zero and $16.1 million of certain raw materials (generally produced by an unrelated third-party manufacturer), respectively.

NOTE 20—SEGMENT REPORTING

The Company’s reportable segments, which are primarily based on the Company’s internal organizational structure and types of products, are itstwo operating segments—Materials and Magnetics (no operating segments have been aggregated).

The Materials segment operates Mountain Pass, which produces rare earth products. The Materials segment currently generates revenue primarily from sales of NdPr oxide and metal, principally sold to customers in the United States, Japan, South Korea, and broader Asia. The Materials segment historically generated revenue from sales of rare earth concentrate into the Chinese market.

The Magnetics segment includes (i) the Independence Facility, where the Company produces and sells magnetic precursor products and, beginning in December 2025, commenced manufacturing NdFeB permanent magnets, and (ii) the 10X Facility. The initial sales from the Independence Facility of magnetic precursor products, including NdPr metal, were made to GM and began in the first quarter of 2025.

The chief operating decision maker (“CODM”) uses Segment Adjusted EBITDA as management’s primary segment measure of profit or loss 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. A reconciliation of total Segment Adjusted EBITDA to consolidated loss before income taxes for the three and six months ended June 30, 2026 and 2025, is included in the tables below.

As the Company’s CODM manages the Company’s assets on a consolidated basis, the CODM is not regularly provided asset information for the reportable segments.

The following tables present the Company’s reportable segment information:
