**CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS**

Certain statements included in this Quarterly Report on Form 10-Q for the three months ended September 30, 2025 (this "Form 10-Q"), that are not historical facts are forward-looking statements under Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements may be identified by the use of the words such as "estimate," "plan," "shall," "may," "project," "forecast," "intend," "expect," "anticipate," "believe," "seek," "will," "target," or similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding estimates and forecasts of other financial and performance metrics and projections of market opportunity. These statements are based on various assumptions, whether or not identified in this Form 10-Q or our Annual Report on Form 10-K for the year ended December 31, 2024 (the "Form 10-K"), and on the current expectations of our management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond our control.

These forward-looking statements are subject to a number of risks and uncertainties, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the heightened significance of the development of the Company's midstream and downstream operations, including ramping its separation capabilities, and its ability to vertically integrate its value chain;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• risks related to the authorization of funding of and continued support for the DoW Transactions (as defined in <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u><u>3[, "Public-Private Partnership with U.S. Department of War"](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u>), to challenges thereto and to the Company's ability, as needed, to obtain additional or replacement funding on terms acceptable to it or at all;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• risks related to the restrictions imposed on the Company's management and operations as a result of the DoW Transactions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• risks related to the Company's long-term agreement with Apple Inc. (NASDAQ: AAPL) ("Apple") and the Company's ability to meet the obligations thereunder, including risks related to its ability to develop, construct and scale its facilities, technology and production;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• risks related to fluctuations in the pricing, cost of production, and volume of the magnets to be produced under the agreement with Apple, and the risk that the Company's estimate of the magnitude and timing of revenues from the agreement will not be realized;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• risks related to changes in trade policy in the United States, China or other countries, including the implementation of new tariffs, and the material adverse impact on the Company's business and results of operations as a result of these changes in trade policy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• risks related to the increased importance of markets outside of China and the Company's ability to sell additional rare earth products in these markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• recent and future volatility in the trading price of our common stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fluctuations and uncertainties related to demand for and pricing of rare earth products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• uncertainties regarding the growth of existing and emerging uses for rare earth products and the Company's ability to compete with substitutions for such products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the intense competition within the rare earth mining and processing and magnetics industries;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• uncertainties relating to significant political, trade, and regulatory developments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• unanticipated costs or delays associated with the Independence Facility or other future magnetics facilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• risks associated with the Company's intellectual property rights, including uncertainties related to the Company's ability to obtain any intellectual property rights or licenses of intellectual property rights to produce certain neodymium-iron-boron ("NdFeB") magnets and precursor products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• uncertainties related to the Company's ability to produce and supply NdFeB magnets and precursor products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the ability to convert current commercial discussions with customers for the sale of rare earth oxide and metal products, NdFeB magnets and other products into contracts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• lower production volumes at the Mountain Pass Rare Earth Mine and Processing Facility due to power outages and interruptions, diminished access to water, equipment failure, spare parts shortages, or process performance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• risks related to technology systems and security breaches;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ability to maintain governmental licenses, registrations, permits, and approvals with numerous governmental agencies necessary for the Company to operate its business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• risks relating to extensive and costly environmental regulatory requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• risks associated with the terms of the Company's convertible debt securities and related options or other hedging arrangements; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the other factors described elsewhere in this Form 10-Q, included under the headings <u>["Management's Discussion and Analysis of Financial Condition and Results of Operations"](#i6b490aec1f4c44c2be48633fcd8a3bdf_118)</u> and <u>[Part II, Item 1A, "Risk Factors"](#i6b490aec1f4c44c2be48633fcd8a3bdf_181)</u> or as described in our Form 10-K, or as described in the other documents and reports we file with the Securities and Exchange Commission (the "SEC").

If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements.

These and other factors that could cause actual results to differ from those implied by the forward-looking statements in this Form 10-Q are more fully described within <u>[Part II, Item 1A, "Risk Factors"](#i6b490aec1f4c44c2be48633fcd8a3bdf_181)</u> in this Form 10-Q and <u>[Part I, Item 1A, "Risk Factors"](https://www.sec.gov/Archives/edgar/data/1801368/000180136825000009/mp-20241231.htm#iadaf5f13b1c64f46a9f722e1c17671e4_64)</u> in our Form 10-K. Such risks are not exhaustive. New risk factors emerge from time to time, and it is not possible to predict all such risk factors, nor can we assess the impact of all such risk factors on our business or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statements. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the foregoing cautionary statements. We undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

In addition, statements of belief and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us, as applicable, as of the date of this Form 10-Q, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain, and you are cautioned not to unduly rely upon these statements.

**MP MATERIALS CORP. AND SUBSIDIARIES**

**NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**(UNAUDITED)**

**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. 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. 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 into two reportable segments: Materials and Magnetics. See <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_97)22[, "Segment Reporting,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_97)</u> for additional information.

The Materials segment represents the upstream and midstream operations of the Company, which primarily consist of Mountain Pass, a fully integrated mining and refining facility producing refined rare earth oxides and related products. The Materials segment generates revenue primarily from sales of neodymium-praseodymium ("NdPr") oxide and metal, primarily sold to customers in Japan, South Korea, and broader Asia. The Materials segment historically generated the majority of its revenue from sales of rare earth concentrate primarily under the Shenghe Offtake Agreement to Shenghe, a related party of the Company (as such terms are defined in <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_94)</u><u>21</u><u>[, "Related-Party Transactions"](#i6b490aec1f4c44c2be48633fcd8a3bdf_94)</u>).

The Magnetics segment represents the downstream magnet manufacturing and related operations of the Company, which currently consist of the Independence Facility, a fully integrated metal, alloy, and magnet manufacturing plant. The Magnetics segment began generating revenue from sales of magnetic precursor products to General Motors Company (NYSE: GM) ("GM") in the U.S. in the first quarter of 2025.

On July 9, 2025, the Company entered into definitive agreements with the United States Department of War (the "DoW"), formerly known as the Department of Defense, (collectively, the "DoW Transaction Agreements") establishing a transformational public-private partnership with the DoW to accelerate the build-out of an end-to-end U.S. rare earth magnet supply chain and reduce foreign dependency (the "DoW Transactions"). This partnership is further described in <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u><u>3[, "Public-Private Partnership with U.S. Department of War](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)[,](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)["](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u> which includes certain defined terms related to the DoW Transaction Agreements. In connection with the DoW Transactions, the Company will expand its Independence Facility, construct a second domestic magnet manufacturing facility (the "10X Facility") and extend its heavy rare earth elements ("HREE") refining capability at Mountain Pass. Additionally, as outlined in the DoW Offtake Agreement, the DoW has guaranteed that the 10X Facility will generate at least $140 million of EBITDA (as defined in the DoW Offtake Agreement, and subject to annual escalation) and has the right to purchase all of the magnets produced at the 10X Facility (which may instead be commercially syndicated). Separately, the Company entered into an NdPr price floor protection agreement with the DoW (the "Price Protection Agreement" or "PPA") for the Company's NdPr products produced at Mountain Pass that are sold or produced and stockpiled starting in the fourth quarter of 2025.

The cash flows and profitability of the Company's operations have historically been significantly affected by the market price of rare earth products, which are generally also impacted by taxes and tariffs. While this volatility will be reduced following the effectiveness of the PPA, certain exposure to market prices remains. 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 focus on accelerating the development of a U.S. supply chain, with export products primarily sold in the Asian market due to the metallization and magnet manufacturing capabilities of the region. See the <u>["Concentration of Risk"](#i782fc78344d847d08d72cf25cb17bd5b_8122)</u> section in <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_40)</u><u>2</u><u>[, "Significant Accounting Policies,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_40)</u> for additional information.

***Basis of Presentation:*** The unaudited Condensed Consolidated Financial Statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP") for interim financial information and with the rules and regulations of the U.S. Securities and Exchange Commission and are presented in U.S. dollars. Accordingly, since they are interim statements, they do not include all of the information and notes required by GAAP for complete consolidated financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.

Results of operations and cash flows for the interim periods presented herein are not necessarily indicative of the results that would be achieved during a full year of operations or in future periods. These unaudited Condensed Consolidated Financial

Statements and notes thereto should be read in conjunction with the Consolidated Financial Statements and notes thereto included in the Company's Form 10-K.

**NOTE 2—SIGNIFICANT ACCOUNTING POLICIES**

***Principles of Consolidation:*** The unaudited Condensed Consolidated Financial Statements include the accounts of MP Materials Corp. and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

***Use of Estimates:*** The preparation of the unaudited Condensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect (i) the reported amounts of assets and liabilities, (ii) the disclosure of contingent assets and liabilities at the date of the unaudited Condensed Consolidated Financial Statements, and (iii) the reported amounts of revenues and expenses during the reporting period. Accordingly, actual results may differ from those estimates.

***Concentration of Risk:*** Financial instruments that potentially subject the Company to credit risk consist principally of cash, cash equivalents and short-term investments, and receivables from customers. The Company believes that its credit risk is limited because the Company's current contracts are with companies that have a reliable payment history. The Company does not believe that it is exposed to any significant risks related to its cash accounts, money market funds, or short-term investments.

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 further sales of its products to China. As a result, rare earth concentrate revenues declined for the three and nine months ended September 30, 2025. Historically, Shenghe was the principal customer of the Materials segment, accounting for approximately 30% of the Company's consolidated revenue for the nine months ended September 30, 2025, the vast majority of which related to sales of concentrate, versus approximately 80% of the Company's consolidated revenue for the nine months ended September 30, 2024 (see <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_94)</u><u>21</u><u>[, "Related-Party Transactions"](#i6b490aec1f4c44c2be48633fcd8a3bdf_94)</u> for additional information).

Rare earth concentrate is not quoted on any major commodities market or exchange and demand for rare earth concentrate is currently constrained to a relatively limited number of refiners, a significant majority of which are based in China. Uncertainty exists as to the market price of rare earth oxide ("REO") primarily due to concerns over the global economic conditions and actual or perceived concerns over increases in the supply of or slower growth in the demand for rare earth products.

Because the Company's revenue is primarily derived from the sale of or other arrangements related to rare earth products, shifts in the market price of these products, including the levying of taxes, tariffs, or other fees, may have a significant negative effect on the Company's results of operations and cash flows, particularly in its Materials segment. However, the PPA is designed to mitigate the effects of these market factors on the Materials segment.

***Accounting for the Price Protection Agreement:*** The PPA is a price floor protection agreement that conveys a contingent right for the Company to receive cash from the DoW and also imposes a contingent obligation for the Company to deliver cash to the DoW in the future as described in <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u><u>3[, "Public-Private Partnership with U.S. Department of War."](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u> Given the contractual cashflows, the right to the price floor protection granted by the DoW under the PPA (the "PPA Upfront Asset") was determined to be a financial instrument. The initially recognized amount of the PPA Upfront Asset results from the difference between the fair value of the other instruments exchanged with the DoW and the cash consideration received from the DoW. The PPA Upfront Asset is presented as "Price protection agreement upfront asset" in non-current assets within the Company's unaudited Condensed Consolidated Balance Sheets as of September 30, 2025. The Company did not elect to apply the fair value option to the PPA Upfront Asset. Beginning October 1, 2025, the PPA's commencement date, the PPA Upfront Asset will be amortized over the Company's expected pattern of economic benefit from the PPA. Reassessment of the PPA Upfront Asset's useful life as well as impairment considerations will be consistent with the Company's existing policies for long-lived assets.

***Price Protection Agreement Income or Expense:*** Beginning in the fourth quarter of 2025, and on a quarterly basis thereafter throughout the PPA's 10-year term, the Company will have the right to receive cash from or an obligation to deliver cash to the DoW. The Company will recognize its rights or obligations as "Price protection agreement expense (income)" within the "Operating expenses and income" section of the Company's unaudited Condensed Consolidated Statements of Operations in the period in which the events giving rise to the right or obligation occur. Each quarterly period represents a distinct contractual period for which amounts receivable or payable will be recognized as earned or incurred.

***Debt Discount and Debt Issuance Costs:*** Debt discount represents the difference between the net proceeds received and the debt's fair value at the time of issuance. Debt issuance costs include incremental third-party costs directly related to the debt issuance. For debt instruments other than the Company's revolving credit facility, debt discount and debt issuance costs are recorded as a direct reduction of the carrying amount of the associated debt instrument and are amortized to interest expense using the effective interest method over the contractual term of the underlying indebtedness. Debt issuance costs related to the Company's revolving credit facility are recorded in "Other non-current assets" within the Company's unaudited Condensed Consolidated Balance Sheets and are amortized to interest expense on a straight-line basis over the term of the revolving credit facility arrangement. See <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u><u>3[, "Public-Private Partnership with U.S. Department of War,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u> and <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_64)</u><u>11</u><u>[, "Debt Obligations,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_64)</u> for additional details.

***Series A Preferred Stock:*** 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 certain redemption rights 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. All financial instruments are evaluated for embedded derivative features by analyzing each feature against the nature of the host instrument (e.g., more equity-like or debt-like). Features identified as freestanding instruments or bifurcated embedded derivatives that are material are recognized separately as a derivative asset or liability. The Company evaluated the Series A Preferred Stock and determined that its nature is that of an equity-host with no embedded derivatives requiring bifurcation. The Company initially recognized the Series A Preferred Stock at its relative fair value, net of allocated issuance costs.

At each reporting period, the Company reassesses whether the Series A Preferred Stock is (i) currently redeemable or (ii) probable of becoming redeemable in the future. If the instrument meets either criterion, the Company will adjust the carrying amount to the estimated maximum redemption value (i.e., the redemption price). As of September 30, 2025, the Series A Preferred Stock was not redeemable, nor probable of becoming redeemable in the future. As such, the carrying amount of the Series A Preferred Stock was not adjusted to the maximum redemption value. See <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_649)</u><u>15</u><u>[, "Redeemable Preferred Stock,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_649)</u> for additional details.

***Warrants:*** The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant's specific terms. The assessment considers whether the warrants are freestanding financial instruments, meet the definition of a liability, and whether the warrants meet all of the requirements for equity classification, including whether the warrants are indexed to the Company's own common stock. The Company analyzed the classification of its outstanding Warrant as of the date of issuance and as of September 30, 2025, and determined that such instrument met the criteria for equity classification. See <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_85)18[, "Stockholders' Equity and Stock-Based Compensation,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_85)</u> for additional information.

***Revenue Recognition:*** For certain product sales primarily within the Magnetics segment, the Company receives requests from a customer to temporarily hold purchased products at the Company's facilities. These products are sold under terms included in bill-and-hold arrangements that may result in different timing for revenue recognition versus shipment. The Company recognizes revenue under these arrangements only when there is a substantive reason for the agreement, the ordered goods are identified separately as belonging to the customer, the goods are currently ready for physical transfer to the customer, and the Company does not have the ability to use the product or to direct it to another customer. Assuming these required revenue recognition criteria are met, revenue is recognized upon completion of product manufacture, which is the point in time control of the product transfers to the customer. See <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_79)</u><u>16</u><u>[, "Revenue Recognition,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_79)</u> for additional information.

***Performance-based Performance Stock Units:*** The Company recognizes the performance-based performance stock units' ("performance-based PSUs") grant-date fair value as compensation cost on a straight-line basis over the requisite service period if it is probable that a performance condition will be achieved. No compensation cost will be recognized for a performance condition that is not probable of being achieved. The Company will re-evaluate at the end of each reporting period whether or not a performance condition is probable of being achieved. If, based on this re-evaluation, the Company estimates an increase in overall compensation cost, then the Company will recognize a cumulative catch-up of compensation cost in the period of the re-evaluation. Alternatively, if the Company estimates a decrease in overall compensation cost, the Company will defer reversing compensation cost until achievement of the performance condition is estimated to be improbable. Previously recognized compensation costs related to forfeited awards will be reversed in the period the forfeiture actually occurs. See <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_85)18[, "Stockholders' Equity and Stock-Based Compensation,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_85)</u> for additional information.

***Convertible Debt and Embedded Derivatives:*** The Company accounts for its convertible debt in accordance with ASC Subtopic 470-20, "Debt with Conversion and Other Options" ("ASC 470-20"), whereby the convertible instrument is initially accounted for as a single unit of account, unless it contains a derivative that must be bifurcated from the host contract in

------

<u>[T](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)[able of Contents](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)</u>

accordance with ASC 815 or the substantial premium model in ASC 470-20 applies. When it is determined that an embedded derivative is required to be bifurcated, the Company recognizes the bifurcated embedded derivative, measured at fair value, as a separate derivative asset or liability upon initial recognition and in subsequent periods at fair value with changes in fair value included in profit or loss each reporting period. Changes in the fair value each reporting period are included in "Other income, net" within the Company's unaudited Condensed Consolidated Statements of Operations.

***Recently Adopted Accounting Pronouncements:*** During the three and nine months ended September 30, 2025, there were no accounting pronouncements adopted by the Company that had a material impact on the Company's unaudited Condensed Consolidated Financial Statements. In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-07, "Improvements to Reportable Segment Disclosures" ("ASU 2023-07"), which expands public entities' segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment's profit or loss and assets. The Company adopted ASU 2023-07 on a retrospective basis as of December 31, 2024, for annual periods, and for interim periods beginning in 2025. See <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_97)22[, "Segment Reporting,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_97)</u> for additional information.

***Recently Issued Accounting Pronouncements:*** The Company is currently evaluating the effect of adopting ASU No. 2024-03, "Income Statement—Reporting Comprehensive Income Expense Disaggregation Disclosures," and ASU No. 2024-04, "Induced Conversions of Convertible Debt Instruments," on its financial statements and/or disclosures.

***Reclassifications:*** Certain amounts in prior periods have been reclassified to conform to the current year presentation.

**NOTE 3—PUBLIC-PRIVATE PARTNERSHIP WITH U.S. DEPARTMENT OF WAR**

On July 9, 2025, the Company entered into the DoW Transaction Agreements, whereby the Company agreed to use its reasonable best efforts to (i) construct the 10X Facility, which will produce sintered NdFeB permanent magnets, (ii) extend HREE refining capability at Mountain Pass to include the separation of samarium oxide, (iii) recommission the chlor-alkali facilities at Mountain Pass and (iv) expand capacity at the Independence Facility to a projected 3,000 metric tons ("MTs") of magnets annually. The Company also agreed to use up to $600 million of its existing cash to fund these projects. Additionally, the DoW Transactions consist of a comprehensive, long-term package of commitments from the DoW, including pricing support, a long-term offtake agreement and certain financing arrangements. Key terms include the following:

***Pricing & Supply Commitments***

***Price Protection Agreement:*** The PPA establishes a price floor for the Company's NdPr products (e.g., concentrate, oxide and metal) (collectively, "NdPr Products") and commences on October 1, 2025, continuing for approximately ten years through December 31, 2035. Throughout the PPA's term, the Company will have the right to receive cash from, or the obligation to deliver cash to, the DoW based on (i) its designation of NdPr Products produced and/or sold (the "NdPr Designation") and (ii) the Benchmark Quarterly Average Volume Weighted Price (as defined in the PPA).

At the conclusion of each quarter, the Company may elect, at its option, any of the following NdPr Designations (without duplication):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "Stockpile" represents produced, but not yet sold NdPr Product,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "Affiliate sales" represents internally sold NdPr Product, such as sales from the Materials segment to the Magnetics segment, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "Third party sales" represents externally sold NdPr Product.

On a quarterly basis, the DoW will pay the Company an amount per kilogram ("KG") equivalent of NdPr Products equal to the shortfall between $110 and the Benchmark Quarterly Average Volume Weighted Price. Once the 10X Facility reaches full production capacity (the "Production Milestone Date"), and the Benchmark Quarterly Average Volume Weighted Price exceeds $110, the Company will pay the DoW 30% of the difference between the Benchmark Quarterly Average Volume Weighted Price and $110.

***DoW Offtake Agreement:*** The Company entered into a magnet offtake agreement with the DoW (the "DoW Offtake Agreement"), pursuant to which the Company will sell to the DoW the entire amount of magnets produced at the 10X Facility; provided, however, that at the DoW's request, or at the Company's request and with the DoW's consent, the Company may sell up to 100% of magnet production to other third-party customers. The DoW will acquire the magnets at a price equal to their production costs (as defined in the DoW Offtake Agreement), plus the guaranteed EBITDA discussed below. The DoW Offtake

------

<u>[T](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)[able of Contents](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)</u>

Agreement has a term of ten years commencing on the date at which the 10X Facility begins operations and is capable of producing any quantity of magnets (the "Commercial Operation Date"). Given the DoW's right to substantially all of the economic benefits of the 10X Facility and its ability to direct the use toward magnet production, the DoW Offtake Agreement meets the definition of a lease for the 10X Facility.

In accordance with the DoW Offtake Agreement, the DoW guaranteed that the 10X Facility will generate at least $140 million of EBITDA (as defined in the DoW Offtake Agreement) on an annual basis after the Production Milestone Date, adjusted annually in each calendar year following 2025 for inflation at a rate equal to 2% (the "Threshold EBITDA Amount"). Between the Commercial Operation Date and the Production Milestone Date, the Company is entitled to a proportion of the Threshold EBITDA Amount based on demonstrated capacity levels. The DoW will make quarterly payments to the Company in an amount equal to 25% of the Threshold EBITDA Amount, subject to annual true up.

On an annual basis, commencing on the Production Milestone Date, if the Company sells magnets to third-party customers, the DoW will be entitled to receive (i) the first $30 million of EBITDA attributable to the 10X Facility that exceeds the Threshold EBITDA Amount (the "Initial Excess Amount") and thereafter (ii) 50% of the EBITDA attributable to the 10X Facility that exceeds the Initial Excess Amount.

Under the DoW Offtake Agreement, before the Commercial Operation Date, the Company is entitled to receive reimbursement from the DoW for certain incremental costs incurred by the Company in connection with engineering, development and start-up of the 10X Facility and for designing magnets to the DoW's specifications (to the extent such costs are not capitalizable as 10X Facility construction costs), with such payments being capped at $30 million in any calendar year.

The DoW Transaction Agreements also provide that the DoW will assist the Company in procuring HREE required for magnet production at the 10X Facility over the duration of the DoW Offtake Agreement. Working capital costs associated with stockpiling or forward purchasing of HREE are also reimbursable by the DoW, with no annual cap, through the Commercial Operation Date.

***Financings***

***Series A Preferred Stock:*** The Company issued 400,000 shares of newly designated Series A Cumulative Perpetual Convertible Preferred Stock, par value $0.0001 per share (the "Series A Preferred Stock") 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. See <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_649)</u><u>15</u><u>[, "Redeemable Preferred Stock,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_649)</u> for additional details.

***Warrant:*** The Company issued a warrant (the "Warrant") to the DoW, exercisable at any time for a period of ten years for up to 11,201,659 shares of the Company's common stock, at an initial exercise price of $30.03 per share, subject to customary anti-dilution adjustments. See <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_85)18[, "Stockholders' Equity and Stock-Based Compensation,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_85)</u> for additional details.

In the aggregate, the common stock into which the Series A Preferred Stock is initially convertible and for which the Warrant is initially exercisable collectively represented 15% of the issued and outstanding shares of the Company's common stock as of July 9, 2025, without giving effect to the issuance of such shares.

***Commitment Letter for Facility Construction:*** In connection with the DoW Transaction Agreements, the Company obtained a commitment letter (the "Commitment Letter") from JPMorgan Chase Funding Inc. and Goldman Sachs Bank USA (along with their affiliates, the "Banks"), pursuant to which the Banks agreed to provide committed secured financing in an amount equal to, in the aggregate, at least $1 billion. The Commitment Letter expired undrawn on its own terms on August 26, 2025, as it was reduced on a dollar-for-dollar basis upon the Offering (as defined in <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_85)18[, "Stockholders' Equity and Stock-Based Compensation"](#i6b490aec1f4c44c2be48633fcd8a3bdf_85)</u>) and the Company's execution of the Revolving Credit Facility (as defined in <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_64)</u><u>11</u><u>[, "Debt Obligations"](#i6b490aec1f4c44c2be48633fcd8a3bdf_64)</u>).

***Samarium Project Loan:*** In August 2025, the Company issued a $150 million unsecured promissory note to the DoW with a 12-year term, maturing on August 1, 2037 (the "Samarium Project Loan"). The Samarium Project Loan was issued for the purpose of the Company extending HREE refining capability at Mountain Pass to include separation of samarium oxide. See <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_64)</u><u>11</u><u>[, "Debt Obligations,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_64)</u> for additional details.

***Consideration Exchanged and Allocation***

The Company issued the Series A Preferred Stock, Warrant, and Samarium Project Loan (the "Issued Instruments"), which had an aggregate fair value of $768.6 million, in exchange for cash and non-cash consideration. Total cash consideration was

------

<u>[T](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)[able of Contents](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)</u>

$550.0 million, consisting of $400.0 million from the issuance of the Series A Preferred Stock and $150.0 million from the issuance of the Samarium Project Loan. The difference between the fair value of the Issued Instruments and the cash consideration received was $218.6 million, which represents the value of the price protection rights provided under the PPA. As a result, the Company received total consideration of $768.6 million.

The Company allocated the total consideration received among the Issued Instruments, considering whether the instruments are measured at fair value on a recurring basis. As none of the Issued Instruments will be measured at fair value on a recurring basis, the $768.6 million was allocated on a relative fair value basis to the Issued Instruments. The Company incurred $11.3 million of capitalizable transaction costs, which were allocated to the Issued Instruments and the PPA on a proportional basis. The following table presents the initially recognized amounts for the DoW Transactions:

The Company does not intend to sell, nor is it more likely than not that the Company will be required to sell any investments in unrealized loss positions before recovery of their amortized cost basis. The Company did not recognize any credit losses related to its available-for-sale investments during the three and nine months ended September 30, 2025, and 2024. The unrealized losses on the Company's available-for-sale investments were primarily due to unfavorable changes in interest rates subsequent to initial purchase. None of the available-for-sale investments held as of September 30, 2025, were in a continuous unrealized loss position for greater than 12 months and the unrealized losses and the related risk of expected credit losses were not material. The Company's gross realized gains and losses were not material for the three and nine months ended September 30, 2025 and 2024.

The Company's interest and investment income, which is included in "Other income, net" within the Company's unaudited Condensed Consolidated Statements of Operations, was as follows:

&nbsp;&nbsp;&nbsp;&nbsp;(1)Primarily represents stockpiled ore and stockpiled bastnaesite concentrate that are not expected to be processed within the next 12 months as well as certain raw materials that are not expected to be consumed within the next 12 months. The stockpiled ore and stockpiled concentrate amounts were $23.8 million and $20.0 million as of September 30, 2025, respectively, and $12.3 million and zero as of December 31, 2024, respectively.

As of September 30, 2025, and 2024, the Company recorded lower of cost or net realizable value reserves of $6.4 million and $15.1 million, respectively, on certain work in process and finished goods inventories. These amounts represent decreases of $0.3 million and $2.7 million from the reserves recorded as of June 30, 2025, and 2024, respectively. The reserves were largely attributable to continued elevated carrying costs of the Company's production of separated products given the current stage of ramping the midstream operations facilities to normalized production levels. Changes in the reserve are included in "Cost of sales (excluding depreciation, depletion and amortization) (including related party)" within the Company's unaudited Condensed Consolidated Statements of Operations.

***Additions to Property, Plant and Equipment:*** The Company capitalized expenditures related to property, plant and equipment of $118.0 million and $130.0 million for the nine months ended September 30, 2025, and 2024, respectively, including amounts not yet paid (see <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_112)</u><u>23</u><u>[, "Supplemental Cash Flow Information"](#i6b490aec1f4c44c2be48633fcd8a3bdf_112)</u>) and excluding equipment purchased with promissory notes (see <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_64)</u><u>11</u><u>[, "Debt Obligations"](#i6b490aec1f4c44c2be48633fcd8a3bdf_64)</u>). The capitalized expenditures for the nine months ended September 30, 2025 and 2024, related primarily to machinery, equipment and assets under construction to support the Company's Independence Facility, as well as various projects at Mountain Pass, including the HREE Facility (as defined in <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_82)</u><u>17</u><u>[, "Government Grants"](#i6b490aec1f4c44c2be48633fcd8a3bdf_82)</u>).

**NOTE 7—EQUITY METHOD INVESTMENT**

The Company's equity method investment balance, which was included in "Other non-current assets" within the Company's unaudited Condensed Consolidated Balance Sheets, was zero and $9.1 million, as of September 30, 2025, and December 31, 2024, respectively, and pertained to the Company's 49% equity interest in VREX Holdco Pte. Ltd. ("VREX Holdco"). VREX Holdco wholly owns Vietnam Rare Earth Company Limited ("VREX"), which owns and operates a metal processing plant and related facilities in Vietnam. At the time of the initial investment, the Company determined that VREX Holdco was a variable interest entity, but that the Company was not the primary beneficiary. Consequently, the Company did not consolidate VREX Holdco, and instead, accounted for its investment in VREX Holdco under the equity method of accounting as it had the ability to exercise significant influence, but not control, over VREX Holdco's operating and financial policies.

In May 2025, the Company sold its 49% interest in VREX Holdco back to VREX Holdco in exchange for a cash payment of $9.7 million. Upon the sale, the Company derecognized its VREX Holdco equity method investment carrying amount and recorded a gain of $1.3 million for the difference between the selling price and the investment's carrying amount; the gain was included in "Other income, net" within the Company's unaudited Condensed Consolidated Statements of Operations for the nine months ended September 30, 2025. No impairment charges were recorded during the three and nine months ended September 30, 2025 and 2024.

The Company's share of VREX Holdco's net loss, which was included in "Other income, net" within the Company's unaudited Condensed Consolidated Statements of Operations, was not material for the nine months ended September 30, 2025, and for the three and nine months ended September 30, 2024.

**NOTE 8—INTANGIBLE ASSETS**

The Company's intangible assets are included within "Other non-current assets" in the Company's unaudited Condensed Consolidated Balance Sheets and consisted of the following:

| **Intangible assets, net** | $6473 | $7370 |

---

Amortization expense related to amortizing intangible assets was $0.3 million and $0.9 million, respectively, for both the three and nine months ended September 30, 2025 and 2024. No impairment charges were recorded during the three and nine months ended September 30, 2025 and 2024.

**NOTE 9—ASSET RETIREMENT AND ENVIRONMENTAL OBLIGATIONS**

***Asset Retirement Obligations***

The Company estimates asset retirement obligations based on the requirements to reclaim certain land areas associated with mineral extraction activities and certain related facilities at Mountain Pass. Minor reclamation activities related to discrete portions of the Company's operations are ongoing. As of September 30, 2025, the Company estimated a significant portion of the cash outflows for major reclamation activities, including the retirement of Mountain Pass, will be incurred beginning in 2053.

As of September 30, 2025, the credit-adjusted risk-free rate ranged between 6.5% and 11.5% depending on the timing of expected settlement and when the increment was recognized. There were no significant increments or decrements for the three and nine months ended September 30, 2025 and 2024.

The non-current portions of the Company's asset retirement obligations, which are included in "Other non-current liabilities" within the Company's unaudited Condensed Consolidated Balance Sheets, were $7.6 million and $7.2 million as of

------

<u>[T](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)[able of Contents](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)</u>

September 30, 2025, and December 31, 2024, respectively. The current portions, which are included in "Other current liabilities" within the Company's unaudited Condensed Consolidated Balance Sheets, were not material. The total estimated future undiscounted cash flows required to satisfy the Company's asset retirement obligations were $51.4 million and $51.6 million as of September 30, 2025, and December 31, 2024, respectively.

***Environmental Obligations***

The Company has certain environmental monitoring and remediation obligations related to the groundwater contamination in and around Mountain Pass. The Company engages environmental consultants to develop remediation plans and the related cost projections, which are used to develop an estimate of future cash payments to estimate the Company's environmental obligations. As assessments and remediation progress occur, the Company periodically reviews its estimates and records any necessary adjustments in the period in which new information becomes available.

As of September 30, 2025, the Company estimated the cash outflows related to these environmental activities will be incurred annually over the next 30 years but could be longer. The Company's environmental obligations are measured at the expected value of future cash outflows discounted to their present value using a discount rate of 4.78%. There were no significant changes in the estimated remaining costs for the three and nine months ended September 30, 2025 and 2024.

The total estimated aggregate undiscounted cost of $38.8 million and $39.5 million as of September 30, 2025, and December 31, 2024, respectively, principally related to groundwater monitoring and remediation activities required by state and local agencies. Based on the Company's estimate of the cost and timing and the assumption that payments are considered to be fixed and reliably determinable, the Company has discounted the liability. The non-current portions of the Company's environmental obligations, which are included in "Other non-current liabilities" within the Company's unaudited Condensed Consolidated Balance Sheets, were $18.1 million as of both September 30, 2025, and December 31, 2024. The current portions, which are included in "Other current liabilities" within the Company's unaudited Condensed Consolidated Balance Sheets, were not material.

***Financial Assurances***

The Company is required to provide certain government agencies with financial assurances relating to closure and reclamation obligations. As of September 30, 2025, and December 31, 2024, the Company had financial assurance requirements of $45.4 million and $45.5 million, respectively, which were satisfied with surety bonds placed with applicable California state and regional agencies.

***Revolving Credit Facility***

In August 2025, the Company entered into a credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and various other lenders, providing a $275.0 million revolving credit facility (the "Revolving Credit Facility"), maturing on August 25, 2030, with a $200.0 million letter of credit facility sublimit (the "Credit Agreement"). As of September 30, 2025, the Company had no outstanding borrowings under the Revolving Credit Facility, $160.0 million of unused letter of credit capacity, and $235.0 million of remaining borrowing capacity under the Revolving Credit Facility.

Interest rates under the Revolving Credit Facility are variable based on the Secured Overnight Financing Rate ("SOFR"), or at the Company's option, at a base reference rate equal to the highest of (i) the federal funds rate plus 0.50%, (ii) the rate of interest last quoted by The Wall Street Journal as the "prime rate" in the U.S., (iii) the one-month SOFR rate plus 1.00% or (iv) 1.00% (the "Base Rate"), plus, as applicable, a margin ranging from 1.75% to 2.50% per annum for SOFR-based loans and ranging from 0.75% to 1.50% per annum for Base Rate-based loans, in each case, depending on the Company's total leverage ratio.

The Credit Agreement is subject to financial covenants that are tested at the end of each fiscal quarter. From the inception of the Credit Agreement until the earlier of the fiscal quarter in which Consolidated EBITDA (as calculated and defined in the Credit Agreement) of the Company equals or exceeds $400.0 million for the test period and the fiscal quarter ending June 30, 2027 (the "Covenant Trigger Event"), the Company must maintain unrestricted cash and cash equivalents of at least $500.0 million. Following the Covenant Trigger Event, the Company is required to maintain a total leverage ratio of less than 4.00:1.00, or 4.50:1.00 for the fiscal quarter of and the three consecutive fiscal quarters following any material acquisition, and a cash interest coverage ratio greater than 3.0:1.0.

The Credit Agreement is guaranteed by the Company and its subsidiaries, subject to certain customary exceptions. Failure to comply with any of the covenants associated with the Credit Agreement could result in a default under its agreements. Such a default would permit lenders to accelerate the maturity of the debt and to foreclose upon any collateral securing such debt. The Company was in compliance with the applicable financial covenant contained in the Credit Agreement as of September 30, 2025.

***Convertible Notes due 2026***

In March 2021, the Company issued $690.0 million in aggregate principal amount of 0.25% unsecured convertible senior notes (the "2026 Notes") at a price of par. Interest on the 2026 Notes is payable on April 1<sup>st</sup> and October 1<sup>st</sup> of each year, beginning on October 1, 2021.

In March 2024, contemporaneous with the pricing of the 2030 Notes (as defined below), the Company entered into privately negotiated transactions with certain holders of the 2026 Notes to repurchase $400.0 million in aggregate principal amount of the 2026 Notes, using $358.0 million of the net proceeds from the offering of the 2030 Notes. The price the Company paid to repurchase the 2026 Notes, 89.5% of par value, was the same for each lender and approximated the trading price of the 2026 Notes at the time of the repurchases. Subsequent to the issuance of the 2030 Notes, the Company repurchased an additional $80.0 million in aggregate principal amount of the 2026 Notes in open market transactions for $70.6 million. As a

<u>[T](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)[able of Contents](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)</u>

result of these repurchases in the first quarter of 2024, the Company recorded a $46.3 million gain on early extinguishment of debt included within the Company's unaudited Condensed Consolidated Statements of Operations for the nine months ended September 30, 2024.

The remaining 2026 Notes outstanding mature, unless earlier converted, redeemed or repurchased, on April 1, 2026, and become convertible at the option of the holder beginning on January 1, 2026, through the business day immediately preceding the maturity date. The initial conversion price of the remaining 2026 Notes is approximately $44.28 per share, or 22.5861 shares per $1,000 principal amount of notes, subject to adjustment upon the occurrence of certain events. As of September 30, 2025, the 2026 Notes are included in "Current portion of long-term debt" within the Company's unaudited Condensed Consolidated Balance Sheets due to the 2026 Notes maturing within one year.

In March 2024, the Company provided a written notice to the trustee and the holders of the 2026 Notes that it has irrevocably elected to fix the settlement method for all conversions that may occur subsequent to the election date, to a combination of cash and shares of the Company's common stock with the specified dollar amount, per $1,000 principal amount of the 2026 Notes, of $1,000. As a result, for any conversions of 2026 Notes occurring after the election date, a converting holder will receive (i) up to $1,000 in cash per $1,000 principal amount of the 2026 Notes and (ii) shares of the Company's common stock for any conversion consideration in excess of $1,000 per $1,000 principal amount of the 2026 Notes converted. Prior to the election being made, the Company could have elected to settle the 2026 Notes in cash, shares of the Company's common stock or a combination thereof.

Prior to January 1, 2026, at their election, holders of the 2026 Notes may convert their outstanding notes under the following circumstances: (i) during any calendar quarter commencing with the third quarter of 2021 if the last reported sale price of the Company's common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (ii) during the five business day period after any five consecutive trading day period (the "2026 Notes measurement period") in which the trading price (as defined in the indenture governing the 2026 Notes) per $1,000 principal amount of 2026 Notes for each trading day of the 2026 Notes measurement period was less than 98% of the product of the last reported sale price of the Company's common stock and the conversion rate on each such trading day; (iii) if the Company calls any or all of the 2026 Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or (iv) upon the occurrence of specified corporate events set forth in the indenture governing the 2026 Notes.

During the third quarter of 2025, the closing price of the Company's common stock exceeded the 130% of the applicable conversion price on at least 20 of the last 30 consecutive trading days, causing the 2026 Notes to be convertible by their holders in the fourth quarter of 2025.

***Convertible Notes due 2030***

In March 2024, the Company issued $747.5 million in aggregate principal amount of 3.00% unsecured convertible senior notes that mature, unless earlier converted, redeemed or repurchased, on March 1, 2030 (the "2030 Notes" and, together with the 2026 Notes, the "Convertible Notes"), at a price of par. Interest on the 2030 Notes is payable on March 1<sup>st</sup> and September 1<sup>st</sup> of each year, beginning on September 1, 2024.

The 2030 Notes are convertible into cash, shares of the Company's common stock or a combination thereof, at the Company's election, at an initial conversion price of approximately $21.74 per share, or 45.9939 shares per $1,000 principal amount of 2030 Notes, subject to adjustment upon the occurrence of certain events.

Prior to December 1, 2029, at their election, holders of the 2030 Notes may convert their outstanding notes under the following circumstances: i) during any calendar quarter commencing with the third quarter of 2024 if the last reported sale price of the Company's common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; ii) during the five business day period after any ten consecutive trading day period (the "2030 Notes measurement period") in which the trading price (as defined in the indenture governing the 2030 Notes) per $1,000 principal amount of 2030 Notes for each trading day of the 2030 Notes measurement period was less than 98% of the product of the last reported sale price of the Company's common stock and the conversion rate on each such trading day; iii) if the Company calls any or all of the 2030 Notes for redemption, the notes called for redemption may be converted at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or iv) upon the occurrence of specified corporate events set forth in the indenture governing the 2030 Notes. On or after December 1, 2029, and prior to the close of business on the second scheduled trading day immediately preceding

the maturity date of the 2030 Notes, holders may convert their outstanding notes at any time, regardless of the foregoing circumstances.

During the third quarter of 2025, the closing price of the Company's common stock exceeded the 130% of the applicable conversion price on at least 20 of the last 30 consecutive trading days, causing the 2030 Notes to be convertible by their holders in the fourth quarter of 2025. As noted above, the settlement method of the 2030 Notes is at the Company's election.

The Company has the option to redeem for cash the 2030 Notes, in whole or in part, beginning on March 5, 2027, if certain conditions are met as set forth in the indenture governing the 2030 Notes. The redemption price is equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest.

***Capped Call Options***

In March 2024, in connection with the offering of the 2030 Notes, the Company entered into privately negotiated capped call transactions (the "Capped Call Options") with certain financial institutions ("Counterparties"). The Capped Call Options cover, subject to anti-dilution adjustments substantially similar to those in the 2030 Notes, 34.4 million shares of the Company's common stock, the same number of shares that initially underlie the 2030 Notes issued in March 2024. The Capped Call Options have an expiration date of March 1, 2030, subject to earlier exercise.

The Capped Call Options are intended, subject to the Company's discretion and depending on whether it elects to exercise its rights under such options, to reduce the potential dilution to the Company's common stock upon conversion of the 2030 Notes and/or offset cash payments the Company is required to make in excess of the principal amount of the converted 2030 Notes, as the case may be. This would apply in the event that the market price per share of the Company's common stock, as measured under the terms of the Capped Call Options, is greater than the strike price of the Capped Call Options, which initially corresponds to the initial conversion price of the 2030 Notes, or approximately $21.74 per share of common stock, with such reduction and/or offset subject to an initial cap of $31.06 per share of the Company's common stock.

The Capped Call Options are separate transactions, entered into by the Company with each of the Counterparties, and are not part of the terms of the 2030 Notes. Holders of the 2030 Notes do not have any rights with respect to the Capped Call Options. The Capped Call Options meet the criteria for classification as equity and, as such, are not remeasured each reporting period. During the first quarter of 2024, the Company paid $65.3 million for the Capped Call Options, which was recorded as a reduction to "Additional paid-in capital" within the Company's unaudited Condensed Consolidated Balance Sheets along with the offsetting associated deferred tax impact of $16.1 million.

The Company elected to integrate the Capped Call Options with those 2030 Notes issued in March 2024 for federal income tax purposes pursuant to applicable U.S. Treasury Regulations. Accordingly, the $65.3 million gross cost of the purchased Capped Call Options will be deductible for income tax purposes as original discount interest over the term of the 2030 Notes.

Interest cost related to the Convertible Notes was as follows:

| &nbsp;&nbsp;&nbsp;&nbsp;**Convertible Notes interest cost** | $7563 | $6711 | $22663 | $16253 |

---

The debt issuance costs associated with the 2026 Notes and the 2030 Notes are being amortized to interest expense over the terms of each note at effective interest rates of 0.51% and 3.52%, respectively. The remaining terms of the 2026 Notes and the 2030 Notes were 0.5 years and 4.4 years, respectively, as of September 30, 2025.

As of September 30, 2025, and December 31, 2024, accrued and unpaid interest pertaining to the Convertible Notes was $2.2 million and $8.7 million, respectively, and is included in "Other current liabilities" within the Company's unaudited Condensed Consolidated Balance Sheets.

***Samarium Project Loan***

As discussed in <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u><u>3[, "Public-Private Partnership with U.S. Department of War,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u> in August 2025, the Company issued a $150 million unsecured promissory note to the DoW with a 12-year term, maturing on August 1, 2037. The Samarium Project

<u>[T](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)[able of Contents](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)</u>

Loan bears interest at a rate of 5.38% per annum, calculated as the 10-year U.S. Treasury constant maturity rate plus 1.00%. Interest on the Samarium Project Loan is payable in cash quarterly in arrears on the 15th day of each calendar quarter, beginning on October 15, 2025. The Samarium Project Loan was recorded at its allocated fair value, based on its relative fair value to the other Issued Instruments. This resulted in a debt discount of $64.0 million as the Samarium Project Loan bears interest at a rate lower than the market interest rate applicable to the Company. See <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u><u>3[, "Public-Private Partnership with U.S. Department of War,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u> for additional information regarding the allocation of consideration and issuance costs. The debt discount and issuance costs associated with the Samarium Project Loan are amortized to interest expense over the term of the note at an effective interest rate of 12.3%. The Company may prepay the Samarium Project Loan, in whole or in part, at any time, including all accrued interest, without premium, cost or penalty. The outstanding principal and all accrued and unpaid interest under the Samarium Project Loan become immediately due and payable upon the occurrence of certain conditions, such as payment defaults, as specified in the promissory note to the DoW.

***Commitment Letter***

As discussed in <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u><u>3[, "Public-Private Partnership with U.S. Department of War,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u> in July 2025, the Company obtained the Commitment Letter from the Banks, pursuant to which the Banks agreed to provide committed secured financing, subject to customary terms and conditions, in an amount equal to, in the aggregate, at least $1 billion. The Commitment Letter expired undrawn under its own terms on August 26, 2025, as it was reduced on a dollar-for-dollar basis by the funding raised through the Offering and upon the Company's execution of the Revolving Credit Facility. In connection with the issuance of the Commitment Letter, the Company incurred $7.4 million of nonrefundable commitment and structuring fees which were recorded as an expense in "Advanced projects and development" within the Company's unaudited Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2025.

***Equipment Notes***

In December 2024, the Company entered into a secured uncommitted non-revolving credit facility (the "Uncommitted Credit Facility") with Caterpillar Financial Services Corporation, providing an aggregate borrowing capacity of $25.0 million, which the Company may use only to finance agreed-upon equipment. During the nine months ended September 30, 2025, the Company executed promissory notes under the Uncommitted Credit Facility to finance new equipment, including trucks and wheel loaders, for use at Mountain Pass. As of September 30, 2025, the Company had no available borrowing capacity under the Uncommitted Credit Facility. The Company's equipment notes, which are secured by the purchased equipment, have terms of between 4 years to 6 years and fixed interest rates of between 6.7% and 7.4% per annum. The purchase of equipment through the execution of these notes is disclosed as a non-cash investing and financing activity in <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_112)</u><u>23</u><u>[, "Supplemental Cash Flow Information."](#i6b490aec1f4c44c2be48633fcd8a3bdf_112)</u>

The current and non-current portions of the equipment notes, which are included within the unaudited Condensed Consolidated Balance Sheets in "Other current liabilities" and "Other non-current liabilities," respectively, were as follows:

As of September 30, 2025, other than the Credit Agreement, none of the agreements governing the Company's indebtedness contain financial covenants.

**NOTE 12—OPERATING LEASES**

The Company's operating leases consist primarily of corporate office space, warehouses, and equipment used in its operations; the Company's finance leases are not material. The Company's lease agreements do not contain material residual value guarantees or restrictive covenants. As of September 30, 2025, the Company was not reasonably certain of exercising any material purchase, renewal, or termination options contained within its lease agreements. No right-of-use asset impairment charges were recorded during the three and nine months ended September 30, 2025 and 2024.

**NOTE 13—INCOME TAXES**

The Company calculates the provision for income taxes during interim reporting periods by applying an estimate of the annual effective tax rate to its year-to-date pretax book income or loss. The tax effects of discrete items, including but not limited to, excess tax benefits or deficiencies associated with stock-based compensation, valuation allowance adjustments based on new evidence, and enactment of tax laws, are reported in the interim period in which they occur. The effective tax rate (income tax expense or benefit as a percentage of income or loss before income taxes) including discrete items was 28.5% and 25.7% for the three and nine months ended September 30, 2025, respectively, as compared to 26.8% and 27.5% for the three and nine months ended September 30, 2024, respectively.

The Company's effective income tax rate can vary from period to period depending on, among other factors, percentage depletion, executive compensation deduction limitations, the Section 45X Advanced Manufacturing Production Credit (the "45X Credit"), and changes to its valuation allowance against deferred tax assets. Certain of these and other factors, including the Company's history and future reversals of existing taxable temporary differences, are considered in assessing its ability to realize its net deferred tax assets. As of September 30, 2025, the Company provided a valuation allowance against certain state tax credits that it believes, based on the weight of available evidence, are not more likely than not to be realized.

In March 2024, the Company was awarded a $58.5 million Section 48C Qualifying Advanced Energy Project Tax Credit (the "48C Credit") to advance the construction on the Independence Facility. The 48C Credit is an investment tax credit equal to 30% of qualified investments for certified projects that meet prevailing wage and apprenticeship requirements and are placed in service after the date of the award. The current and noncurrent portions of the 48C Credit recognized are included in "Other current liabilities" and "Deferred investment tax credit," respectively, within the Company's unaudited Condensed Consolidated Balance Sheets.

In July 2025, the One Big Beautiful Bill Act ("OBBBA") was enacted into law. Among other provisions, the OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act and the phase-out of the 45X Credit by 2034. The enactment of the tax reform provisions did not have a material impact on our unaudited Condensed Consolidated Financial Statements.

**NOTE 14—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. Other than the matter described below, 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.

The Company is currently in a dispute with a general contractor for a construction project, which is in binding arbitration. While the Company disputes that it owes any monies (and believes it has a valid claim against the contractor) in connection with this construction project, at present, the Company has accrued an estimate of the potential loss, which is included in "Accrued construction costs" within "Accrued liabilities" in the Company's unaudited Condensed Consolidated Balance Sheets. If an unfavorable outcome were to occur in the binding arbitration, it is possible that the impact could be material to the Company's consolidated financial statements in the period in which the contingency is resolved.

**NOTE 15—REDEEMABLE PREFERRED STOCK**

On July 10, 2025, the Board of Directors for the Company authorized the designation of 400,000 shares of Series A Preferred Stock with a stated value of $1,000 per Series A Preferred Stock (the "Stated Value") from the Company's existing 50,000,000 authorized but unissued shares of preferred stock. The Company issued the authorized Series A Preferred Stock through a private placement to the DoW for cash consideration of $400.0 million.

The Series A Preferred Stock was initially recorded at its allocated fair value, based on its relative fair value to the other Issued Instruments, of $413.6 million, net of allocated issuance costs of $4.8 million (see <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u><u>3[, "Public-Private Partnership with U.S. Department of War,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u> for additional information regarding the allocation of consideration and issuance costs). As of September 30, 2025, the carrying amount of the Company's Series A Preferred Stock, net of issuance costs, was $413.6 million. 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 September 30, 2025. 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.

***Dividends:*** Shares of the Series A Preferred Stock accrue cumulative dividends at a rate of 7.0% per year, compounding quarterly and payable solely in-kind through an increase to the Stated Value of each share of Series A Preferred Stock (each such dividend, a "PIK Dividend"). The Stated Value plus compounded PIK Dividends (the "Accumulated Stated Value") is only payable by the Company in cash or other assets upon the occurrence of certain insolvency events, including a deemed liquidation event (i.e., it represents the liquidation preference of the holders of the Series A Preferred Stock). Further, the PIK Dividend does not influence the conversion price or the number of common shares that would be issued to the holders of the Series A Preferred Stock upon conversion. As the PIK Dividend is a liquidation preference, it will not be accounted for as an adjustment to the Series A Preferred Stock's carrying amount until a deemed liquidation event occurs or becomes probable of occurring.

The holders of the Series A Preferred Stock also participate in any dividends declared and paid to holders of the Company's common stock. Within 15 business days following the end of a calendar year, the Company will pay cash to the holder of each share of Series A Preferred Stock, on an as-converted basis, the amount, if any, by which the aggregate cash dividends paid by the Company on each share of common stock in the prior year exceed 7.0% of the Company's common stock closing share price on the last trading day of the preceding year (the "Special Payment").

***Voting Rights:*** The Series A Preferred Stock is nonvoting on all matters, other than those that would have a material adverse effect on the special rights, powers, preferences or privileges of the Series A Preferred Stock.

***Conversion:*** 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, subject to customary anti-dilution adjustments.

At the election of the Company, any time after the five-year anniversary of issuance, if the closing price per share of the Company's common stock exceeds 150% of the then-current conversion price for at least 20 trading days in any period of 30 consecutive trading days, the Company may elect to convert all or any portion of the then-outstanding shares of Series A Preferred Stock into common stock at the then-current conversion price.

***Redemption:*** Redemption is contingent upon certain insolvency events, including a deemed liquidation event, or upon certain reorganization events (e.g., share exchange, recapitalization, consolidation, or merger). The Series A Preferred Stock is classified as redeemable preferred stock (i.e., temporary 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.

***Liquidation Rights:*** 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 Accumulated Stated Value plus 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 September 30, 2025, and December 31, 2024, the aggregate minimum liquidation preference was $406.4 million and zero, respectively, which is represented by the Liquidation Floor.

Rare earth concentrate revenue was primarily generated from sales to Shenghe under the Shenghe Offtake Agreement. The sales price of rare earth concentrate sold to Shenghe was based on a preliminary market price (net of taxes, tariffs, and certain other agreed charges) per MT and estimated exchange rate between the Chinese yuan and the U.S. dollar, with an adjustment for the ultimate market price of the product realized by Shenghe upon sales to their customers, including the impact of changes in the exchange rate between the Chinese yuan and the U.S. dollar.

NdPr oxide and metal revenue was generated from individual sales agreements as well as sales made under the Company's distribution agreement with Sumitomo Corporation of Americas.

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. During the three and nine months ended September 30, 2025, the Company recognized $21.9 million and $47.0 million, respectively, of revenue under a bill-and-hold arrangement, under which control of the product transfers to the customer, but the product remains in the physical possession of the Company. The performance obligation is satisfied at the point in time the finished product is packaged, segregated and ready for shipment to GM. There were no bill-and-hold transactions during the three and nine months ended September 30, 2024.

Additionally, on July 14, 2025, the Company entered into a definitive, long-term supply agreement with 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 September 30, 2025, the Company had not yet recognized any revenue under this arrangement.

***Contract Balances:*** The Company recognizes revenue based on the criteria set forth in ASC Topic 606, "Revenue from Contracts with Customers." Given the nature of the Company's contracts with customers, contract assets are not material for any period presented. Furthermore, the amount of revenue recognized in the periods presented from performance obligations that were satisfied (or partially satisfied) in previous periods were not material to any period presented.

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 or has the unconditional right to receive consideration in advance of such transfer. Deferred revenue decreases as revenue is recognized from the satisfaction of the related performance obligations.

Pursuant to the long-term agreement with GM, GM prepaid to the Company $50.0 million in April 2025 and $100.0 million during the year ended December 31, 2024, for magnetic precursor products. The $50.0 million received in April 2025 was the final prepayment for magnetic precursor products under the long-term agreement with GM.

As of September 30, 2025, the Company classified $82.2 million of the $103.0 million total remaining prepayment from GM as current deferred revenue and $20.8 million as non-current deferred revenue in its unaudited Condensed Consolidated Balance Sheets based on the Company's expectation of when the performance obligations will be satisfied. The Company currently estimates that the performance obligations associated with the current deferred revenue from GM will be satisfied within one year after September 30, 2025, and between approximately one and two years after the same date for the non-current deferred revenue from GM. 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.

Pursuant to the definitive, long-term supply agreement with Apple, Apple made an initial prepayment to the Company $40.0 million in September 2025.

As of September 30, 2025, the Company classified the $40.0 million from Apple as non-current deferred revenue in its unaudited Condensed Consolidated Balance Sheets based on the Company's expected satisfaction of the associated performance obligation beginning in 2027.

**NOTE 17—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 nine months ended September 30, 2025, the Company received $24.2 million from the DoW under the HREE Production Project Agreement. No such funds were received from the DoW during the nine months ended September 30, 2024.

***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 September 30, 2025, and December 31, 2024, the government grant receivable balance and deferred government grant balance within the Company's unaudited Condensed Consolidated Balance Sheets pertained to the 45X Credit. During the third quarter of 2024, the Company received $19.4 million related to the 45X Credit claimed on its 2023 federal tax return. The current portion of deferred government grant, which is included in "Other current liabilities," was $2.3 million and $2.0 million as of September 30, 2025 and December 31, 2024, respectively.

**NOTE 18—STOCKHOLDERS' EQUITY AND STOCK-BASED COMPENSATION**

***Public Offering of Common Stock***

In July 2025, the Company completed an underwritten public offering of 13,590,908 shares of the Company's common stock, par value $0.0001 per share, at a price to the public of $55.00 per share (the "Offering"). The underwriters purchased the shares of common stock at the price of $53.35, including the full exercise of the underwriters' option to purchase additional shares of the Company's common stock, solely to cover over-allotments. The Company's net proceeds from the Offering were $724.2 million, after deducting underwriting discounts and commissions and other offering expenses payable by the Company.

***Warrant***

As discussed in <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u><u>3[, "Public-Private Partnership with U.S. Department of War,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u> on July 10, 2025, the Company issued 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 of ten 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. The Warrant was classified as an equity instrument included in "Additional paid-in capital" within the Company's unaudited Condensed Consolidated Balance Sheets and was initially recorded at its allocated fair value, based on its relative fair value to the other Issued Instruments, of $261.2 million, net of allocated issuance costs of $3.0 million (see <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u><u>3[, "Public-Private Partnership with U.S. Department of War,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_569)</u> for additional information regarding the allocation of consideration and issuance costs). As of September 30, 2025, no shares of common stock had been issued pursuant to the exercise of the Warrant.

***Treasury Stock***

In March 2024, the Company's Board of Directors approved a share repurchase program (the "Program") effective for one year under which the Company became authorized to repurchase up to an aggregate amount of $300.0 million of the Company's outstanding common stock. In August 2024, the Company's Board of Directors approved a $300.0 million increase to the Program, bringing the total authorized amount to $600.0 million. The authorization did not require the purchase of any minimum number of shares. On July 11, 2025, pursuant to the terms of the DoW Transaction Agreements, the Company terminated the Program, which would have otherwise continued until August 30, 2026.

During the three and nine months ended September 30, 2024, the Company repurchased 2.2 million and 15.2 million shares, respectively, of its common stock at an aggregate cost of $24.3 million and $225.1 million, respectively. Of the number of shares repurchased during the nine months ended September 30, 2024, 12.3 million were repurchased in March 2024 contemporaneous with the 2030 Notes offering using $191.6 million of the net proceeds from such offering. The shares repurchased in connection with the 2030 Notes offering were privately negotiated transactions with or through one of the initial purchasers of the 2030 Notes or its affiliate at a price of $15.53 per share, which was equal to the closing price per share of common stock on the date of such transactions. No shares were repurchased during the three and nine months ended September 30, 2025.

***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 either or a combination of market- or performance-based goals. As of September 30, 2025, the Company has not issued any stock options or SARs and there were 4,592,490 shares available for future grants under the 2020 Incentive Plan.

***Performance-Based PSUs*:** In March 2025, pursuant to the 2020 Incentive Plan, the Compensation Committee of the Company's Board of Directors adopted a performance share plan (the "2025 Performance Share Plan"). Pursuant to the 2025 Performance Share Plan, during the nine months ended September 30, 2025, the Company granted 235,533 of performance-based PSUs at target, all of which cliff vest after a requisite performance period of three years. The performance-based PSUs have a requisite service period of approximately three years and have the potential to be earned in 50% increments between 0% and 200% of the number of granted awards depending on the achievement of the performance conditions. The fair value of these performance-based PSUs was determined using the Company's stock price on the grant date.

The Company's stock-based compensation was recorded as follows:

**NOTE 19—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 the carrying amounts because of the immediate or short-term maturity of these financial instruments.

***Cash, Cash Equivalents and Restricted Cash***

The fair values of the Company's cash, cash equivalents and restricted cash are 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.

***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:

**NOTE 20—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 two-class method determines net income or loss attributable to each class of common stock and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method 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. The Company's Series A Preferred Stock contractually entitles the holders of such shares to potentially participate in dividends by way of the Special Payment (as further described in <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_649)</u><u>15</u><u>[, "Redeemable Preferred Stock"](#i6b490aec1f4c44c2be48633fcd8a3bdf_649)</u>), but does not

contractually require the holders of such shares to participate in the Company's losses. As such, 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 by the weighted-average number of common shares outstanding, both adjusted by the effect of dilutive potential common shares outstanding during the period using the treasury stock method, the if-converted method, or the two-class method, as applicable.

The following table reconciles the weighted-average common shares outstanding used in the calculation of basic earnings or loss per common share to the weighted-average common shares outstanding used in the calculation of diluted earnings or loss per common share:

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 September 30, 2025.

As discussed in <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_64)</u><u>11</u><u>[, "Debt Obligations,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_64)</u> in March 2024, the Company provided a written notice to the trustee and the holders of the 2026 Notes that it has irrevocably elected to fix the settlement method for all conversions that may occur subsequent to the election date, to a combination of cash and shares of the Company's common stock with the specified dollar amount per $1,000 principal amount of the 2026 Notes of $1,000. As a result, subsequent to the election, only the amounts in excess of the principal amount are considered in diluted earnings or loss per share. The amount of the 2026 Notes settled in shares of common stock will have a dilutive impact on diluted earnings or loss per share when the average market price of the Company's common stock for a given period exceeds the conversion price, which was initially approximately $44.28 per share of common stock.

**NOTE 21—RELATED-PARTY TRANSACTIONS**

***Shenghe Offtake Agreement:*** In January 2024, the Company entered into an offtake agreement (the "Shenghe 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 replaced and extended the offtake agreement with Shenghe entered into in March 2022.

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. Under the Shenghe Offtake Agreement, Shenghe was paid a variable commission on net proceeds to the Company.

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 China and will not extend the term of the Shenghe Offtake Agreement when it expires in January 2026.

***Tolling Agreement with VREX Holdco:*** In October 2023, the Company entered into a tolling agreement with VREX Holdco (the "Tolling Agreement"), which has an initial term of three years with options to be renewed for additional three-year terms. Pursuant to the Tolling Agreement, the Company delivered NdPr oxide to VREX Holdco, which VREX Holdco then

**NOTE 22—SEGMENT REPORTING**

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 (no operating segments have been aggregated). Where applicable, 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 Mountain Pass, which produces refined rare earth products as well as rare earth concentrate and related products. The Materials segment generates revenue primarily from sales of NdPr oxide and metal, primarily sold to customers in Japan, South Korea, and broader Asia. The Materials segment historically also generated revenue from sales of rare earth concentrate, which was primarily sold for further distribution to a single customer in China. Refer to the <u>["Concentration of Risk"](#i782fc78344d847d08d72cf25cb17bd5b_8122)</u> section in <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_40)</u><u>2</u><u>[, "Significant Accounting Policies,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_40)</u> and <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_94)</u><u>21</u><u>[, "Related-Party Transactions,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_94)</u> for additional information.

The Magnetics segment operates the Independence Facility, where the Company produces and sells magnetic precursor products and anticipates manufacturing NdFeB permanent magnets by the end of 2025. The first sales of magnetic precursor products, including NdPr metal, were made to GM and were recognized during the first quarter of 2025.

The 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 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 nine months ended September 30, 2025 and 2024, 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.

**Business Overview**

MP Materials Corp., including its subsidiaries ("we," "our," "us" and the "Company"), is the largest producer of rare earth materials in the Western Hemisphere. We own and operate 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. 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. We are also developing a rare earth metal, alloy and magnet manufacturing facility in Fort Worth, Texas ("Independence" or the "Independence Facility").

Our reportable segments, which are primarily based on our internal organizational structure and types of products, are our two operating segments—Materials and Magnetics. Where applicable, 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 represents our upstream and midstream operations, which primarily consist of Mountain Pass, a fully integrated mining and refining facility producing refined rare earth oxides and related products. The Materials segment generates revenue primarily from sales of neodymium-praseodymium ("NdPr") oxide and metal, primarily sold to customers in Japan, South Korea, and broader Asia. The Materials segment historically generated the majority of its revenue from sales of rare earth concentrate primarily to a single customer in China.

The Magnetics segment represents our downstream magnet manufacturing and related operations, which currently consist of the Independence Facility, a fully integrated metal, alloy, and magnet manufacturing plant. The Magnetics segment began generating revenue from sales of magnetic precursor products to a single customer in the U.S., in the first quarter of 2025, and we anticipate manufacturing neodymium-iron-boron ("NdFeB") permanent magnets by the end of 2025.

Certain rare earth elements ("REE") serve as critical inputs for the rare earth magnets inside the electric motors and generators powering carbon-reducing technologies such as hybrid and electric vehicles (referred to collectively as "xEVs") and wind turbines, as well as drones, defense systems, robotics and many other high-growth, advanced technologies. Our integrated operations combine low production costs with high environmental standards, thereby restoring American leadership to a critical industry with a strong commitment to sustainability.

In July 2025, we completed an underwritten public offering of 13,590,908 shares of our common stock, par value $0.0001 per share, at a price to the public of $55.00 per share (the "Offering"). The underwriters purchased the shares of common stock at the price of $53.35, including the full exercise of the underwriters' option to purchase additional shares of our common stock, solely to cover over-allotments. Our net proceeds from the Offering were $724.2 million, after deducting underwriting discounts and commissions and other offering expenses.

***Agreement with Apple Inc.***

In July 2025, we entered into a definitive, long-term supply agreement with Apple Inc. (NASDAQ: AAPL) ("Apple") for the development, manufacture, and supply of magnets from our 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 us, of which we received $40.0 million during the third quarter of 2025.

***Public-Private Partnership with U.S. Department of War***

On July 9, 2025, we entered into definitive agreements with the United States Department of War (the "DoW"), formerly known as the Department of Defense, (collectively, the "DoW Transaction Agreements") establishing a transformational public-private partnership with the DoW to accelerate the build-out of an end-to-end U.S. rare earth magnet supply chain and reduce foreign dependency (the "DoW Transactions").

As part of the DoW Transactions, we agreed to use reasonable best efforts to (i) construct a second domestic magnet manufacturing facility (the "10X Facility"), which will produce sintered NdFeB permanent magnets, (ii) extend heavy rare earth elements ("HREE") refining capability at Mountain Pass to include the separation of samarium oxide, (iii) recommission the chlor-alkali facilities at Mountain Pass and (iv) expand capacity at the Independence Facility to a projected 3,000 metric tons ("MTs") of magnets annually. We have also agreed to use up to $600 million of our existing cash to fund these projects.

Additionally, the DoW Transactions consist of a comprehensive, long-term package of commitments from the DoW, including pricing support, a long-term offtake agreement and certain financing arrangements. Key terms include the following:

*Pricing & Supply Commitments*

*Price Protection Agreement*

The PPA establishes a price floor for our NdPr products (e.g., concentrate, oxide and metal) (collectively, "NdPr Products") and commences on October 1, 2025, continuing for approximately ten years through December 31, 2035. Throughout the PPA's term, we will have the right to receive cash from, or the obligation to deliver cash to, the DoW based on (i) our designation of NdPr Products produced and/or sold (the "NdPr Designation") and (ii) the Benchmark Quarterly Average Volume Weighted Price (as defined in the PPA).

At the conclusion of each quarter, we may elect, at our option, any of the following NdPr Designations (without duplication):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "Stockpile" represents produced, but not yet sold NdPr Product,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "Affiliate sales" represents internally sold NdPr Product, such as sales from the Materials segment to the Magnetics segment, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "Third party sales" represents externally sold NdPr Product.

On a quarterly basis, the DoW will pay us an amount per kilogram ("KG") equivalent of NdPr Products equal to the shortfall between $110 and the Benchmark Quarterly Average Volume Weighted Price. Once the 10X Facility reaches full production capacity (the "Production Milestone Date"), and the Benchmark Quarterly Average Volume Weighted Price exceeds $110, we will pay the DoW 30% of the difference between the Benchmark Quarterly Average Volume Weighted Price and $110.

*DoW Offtake Agreement*

We entered into a magnet offtake agreement with the DoW (the "DoW Offtake Agreement"), pursuant to which we will sell to the DoW the entire amount of magnets produced at the 10X Facility; provided however, that at the DoW's request, or at our request and with the DoW's consent, we may sell up to 100% of magnet production to other third-party customers. The DoW will acquire the magnets at a price equal to their production costs (as defined in the DoW Offtake Agreement), plus the guaranteed EBITDA discussed below. The DoW Offtake Agreement has a term of ten years commencing on the date at which the 10X Facility begins operations and is capable of producing any quantity of magnets (the "Commercial Operation Date"). Given the DoW's right to substantially all of the economic benefits of the 10X Facility and its ability to direct the use toward magnet production, the DoW offtake Agreement meets the definition of a lease for the 10X Facility.

In accordance with the DoW Offtake Agreement, the DoW guaranteed that the 10X Facility will generate at least $140 million of EBITDA (as defined in the DoW Offtake Agreement) on an annual basis after the Production Milestone Date, adjusted annually in each calendar year following 2025 for inflation at a rate equal to 2% (the "Threshold EBITDA Amount"). Between the Commercial Operation Date and the Production Milestone Date, we are entitled to a proportion of the Threshold

------

<u>[T](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)[able of Contents](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)</u>

EBITDA Amount based on demonstrated capacity. The DoW will make quarterly payments to us in an amount equal to 25% of the Threshold EBITDA Amount, subject to annual true up.

On an annual basis, commencing on the Production Milestone Date, if we sell magnets to third-party customers, the DoW will be entitled to receive (i) the first $30 million of EBITDA attributable to the 10X Facility that exceeds the Threshold EBITDA Amount (the "Initial Excess Amount") and thereafter (ii) 50% of the EBITDA attributable to the 10X Facility that exceeds the Initial Excess Amount.

Under the DoW Offtake Agreement, before the Commercial Operation Date, we are entitled to receive reimbursement from the DoW for certain incremental costs incurred by us in connection with engineering, development and start-up of the 10X Facility and for designing magnets to the DoW's specifications (to the extent such costs are not capitalizable as 10X Facility construction costs), with such payments being capped at $30 million in any calendar year.

The DoW Transaction Agreements also provide that the DoW will assist us in procuring HREE required for magnet production at the 10X Facility over the duration of the DoW Offtake Agreement. Working capital costs associated with stockpiling or forward purchasing of HREE are also reimbursable by the DoW, with no annual cap, through the Commercial Operation Date.

*Financings*

As part of the financing for the projects described above, we issued 400,000 shares of newly designated Series A Cumulative Perpetual Convertible Preferred Stock, par value $0.0001 per share (the "Series A Preferred Stock") to the DoW for cash consideration of $400 million. At the election of the DoW, the Series A Preferred Stock is convertible at any time into 13,320,013 shares of our common stock at an initial conversion price of $30.03 per share, subject to customary anti-dilution adjustments. See <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_649)</u><u>15</u><u>[, "Redeemable Preferred Stock,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_649)</u> in the notes to the unaudited Condensed Consolidated Financial Statements for additional details.

We also issued a warrant (the "Warrant") to the DoW, exercisable at any time for a period of ten years for up to 11,201,659 shares of our common stock, at an initial exercise price of $30.03 per share, subject to customary anti-dilution adjustments. In the aggregate, the common stock into which the Series A Preferred Stock is initially convertible and for which the Warrant is initially exercisable collectively represented 15% of the issued and outstanding shares of our common stock as of July 9, 2025, without giving effect to the issuance of such shares.

In addition to the issuance of securities, we also obtained a commitment letter (the "Commitment Letter") from JPMorgan Chase Funding Inc. and Goldman Sachs Bank USA (along with their affiliates, the "Banks"), pursuant to which the Banks agreed to provide committed secured financing in an amount equal to, in the aggregate, at least $1 billion. The Commitment Letter expired undrawn on its own terms on August 26, 2025, as it was reduced on a dollar-for-dollar basis upon the Offering and our execution of the Revolving Credit Facility (as defined in the <u>["Liquidity and Capital Resources"](#i6b490aec1f4c44c2be48633fcd8a3bdf_148)</u> section below).

Finally, in August 2025, we issued a $150 million unsecured promissory note to the DoW with a 12-year term, maturing on August 1, 2037 (the "Samarium Project Loan"). The Samarium Project Loan was issued for the purpose of extending HREE refining capability at Mountain Pass to include the separation of samarium oxide. See the <u>["Liquidity and Capital Resources"](#i6b490aec1f4c44c2be48633fcd8a3bdf_148)</u> section below for additional details.

***VREX Holdco Equity Method Investment Exit***

During the second quarter of 2025, we sold our 49% interest in VREX Holdco Pte. Ltd. ("VREX Holdco") back to VREX Holdco in exchange for a cash payment equal to our initial investment amount of $9.7 million. See <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_52)</u><u>7</u><u>[, "Equity Method Investment,"](#i6b490aec1f4c44c2be48633fcd8a3bdf_52)</u> in the notes to the unaudited Condensed Consolidated Financial Statements for additional information.

***Cessation of Shipments to China and Stockpiling of Rare Earth Concentrate***

Historically, through our Materials segment, we sold the vast majority of our rare earth concentrate to a single, principal customer in China under the terms of the Shenghe Offtake Agreement (as defined in <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_94)</u><u>21</u><u>[, "Related-Party Transactions"](#i6b490aec1f4c44c2be48633fcd8a3bdf_94)</u>). In July 2025, to align with the terms of the DoW Transaction Agreements and in further support of our domestic supply chain objectives, we ceased all sales of our products to China.

We continue to produce concentrate, and to the extent not sold or further processed and sold as separated product, we stockpile that concentrate for future use. In addition, we are prioritizing accelerating our downstream operations, as well as focusing on generating sales of separated products to customers.

------

<u>[T](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)[able of Contents](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)</u>

The cessation of shipments had, at least in the short-term, a material negative impact on our business, operating results, financial performance and financial condition, cash flows and liquidity.

**Factors Affecting Our Performance**

We believe we are uniquely positioned to capitalize on the trends of electrification and supply chain security, particularly as domestic xEV production and domestic industrial supply chain initiatives grow. Our continued success depends to a significant extent on our ability to take advantage of the following opportunities and meet the challenges associated with them.

***Demand for REE***

The key demand drivers for REE are a diverse array of growing end markets, including electric mobility; physical AI; industrial, consumer and professional service robotics; renewable power generation; energy-efficient motors, pumps, and compressors; consumer and medical applications; critical defense systems; and catalysts and phosphors. Accordingly, the demand for our products may be impacted by demand for these downstream products, particularly the continued growth in xEVs. Despite the current macroeconomic conditions, we continue to believe that we benefit from the growth of the rare earth market, particularly the market for NdPr and permanent magnets, and from several demand tailwinds for REE. These include the trend toward electrification; implementation of physical AI; geographic supply chain diversification, particularly in relation to China; the U.S. government initiatives to restore domestic supply of critical minerals; and the increasing requirement for environmentally-conscious production methods.

In April 2025, China imposed export controls, which included export restrictions on seven HREE and certain magnet materials containing HREE. The new restrictions require companies to secure special export licenses to export the specified REE and magnet materials containing HREE. In addition, in October 2025, China expanded these measures by adding several rare earths and related materials to its export control list and by requiring foreign companies to obtain Chinese government approval for the export of products containing even small amounts of Chinese-origin rare earths, as well as technologies related to mining, separation, and magnet manufacturing. These developments have led and continue to lead to several market trends, which may or may not be permanent, including disruptions in supply chains, shortages of rare earth elements, potential price volatility, and an increased demand for alternative supply chains outside of China, all of which, if sustained, may have a material impact on the demand for our products.

Changes in technology could reduce the use of REE, including NdPr, in the components in which they are now used, or lead to a decline in reliance on such components altogether. Additionally, export controls and supply chain disruptions may also incentivize companies and governments to build alternative supply chains and create economic pressure to identify or create alternate technologies that ultimately could depress long-term demand for rare earth minerals and products, and at the same time may incentivize development of competing mining properties. Actual, or perceived, decreases in demand for REE, whether through changes in technology or slower growth in the end markets that utilize REE, could result in a decline in the market price of REE, including NdPr, and/or result in pricing volatility. We also operate in a competitive industry. Many of our key competitors are based in China, where competitors may not be subject to the same rigorous environmental standards or may receive disproportionate government subsidies, and production costs are typically lower than in the U.S.

***Maximizing Upstream ("Stage I") and Midstream ("Stage II") Production Efficiency***

Following the implementation of our Stage I optimization plan, we have reached at least 40,000 MTs of annual REO Production Volume since 2021. These results were achieved by optimizing the reagent scheme, reducing process temperatures, improving tailings facility management, and committing to operational excellence, which allowed us to achieve record production levels in 2024 and 2025. Our Stage I optimization plan has enabled us to attain what we believe to be world-class production cost levels for rare earth concentrate.

In November 2023, we announced our "Upstream 60K" strategy whereby we intend to grow our annual REO Production Volume to approximately 60,000 MTs by expanding upstream capacity via investments in further beneficiation, including the ability to process alternative feedstocks and upgrade lower-grade feedstocks. We aim to achieve this initiative within the next three years with modest incremental capital investment.

Stage II advanced our operations from the production of rare earth concentrate to the separation of individual REE. The Stage II optimization project incorporated upgrades and enhancements to the prior facility process flow to produce separated REE at a lower cost while minimizing our impact on the environment. More specifically, we have reintroduced an oxidizing roasting circuit, reoriented portions of the plant process flow, increased product finishing capacity, improved wastewater management, and made other improvements to materials handling and storage. The reintroduction of the oxidizing roasting

------

<u>[T](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)[able of Contents](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)</u>

circuit allows subsequent stages of the production process to occur at lower temperatures, and with lower volumes of materials and reagents, which supports lower operating and maintenance costs and higher uptime than would otherwise be achievable.

The success of our business reflects our ability to continue to manage our costs and drive scale. Our upstream production achievements have provided economies of scale to lower production costs per MT of REO produced in concentrate. Furthermore, we designed our midstream process flow to capitalize on the inherent advantages of the bastnaesite ore at Mountain Pass, which is well-suited to low-cost refining by selectively eliminating the need to carry cerium, a lower-value element, through the separations process. Additionally, our location and integration offer cost and transportation advantages that create meaningful efficiencies in production, security of incoming supplies and shipping of our final products.

During the second half of 2023, we began producing separated rare earth products. We continue to expect that it may take many quarters to achieve our designed throughput of separated products. As we increase production of separated products over time, we expect to reduce our per-unit production costs of NdPr oxide, which represents a majority of the value contained in our concentrate. Until such time, we may experience unstable operations and elevated costs of our initial production of separated products.

As part of our partnership with the DoW, we have committed to further extend our refining capabilities to include the separation of samarium oxide and to recommission the chlor-alkali facilities at Mountain Pass. Additionally, as part of our agreement with Apple, we will develop and install scaled magnet recycling capabilities at Mountain Pass.

We currently generate our revenue primarily from our Materials segment, which operates a single site in a single location, and any stoppage in activity, including for reasons outside of our control, could adversely impact our production, results of operations and cash flows.

***Development of Our Downstream Manufacturing Capabilities ("Stage III")***

We are completing the installation of equipment at Independence and continue to develop engineering and manufacturing technology to process NdPr oxide into metal, alloy and magnets, while incorporating magnet recycling capabilities. These initiatives support our long-term plans to become a leading global source for rare earth magnets. We believe this vertical integration is a core competitive advantage in the production of a critical industrial output. We expect our downstream manufacturing efforts to continue to benefit from geopolitical developments, including initiatives to repatriate critical materials supply chains, such as through our agreements with the DoW and Apple described in the <u>["Recent Developments"](#i6b490aec1f4c44c2be48633fcd8a3bdf_124)</u> section above.

In 2024, we commissioned our electrowinning capability to produce NdPr metal from NdPr oxide at Independence. Further, we introduced capabilities to produce neodymium-praseodymium-iron-boron alloy flake, a key precursor product that is utilized as the material feedstock for magnet manufacturing. In addition, we recently began trial production of automotive-grade, sintered NdFeB magnets at our new product introduction ("NPI") facility within Independence. We began generating revenue from sales of magnetic precursor products in the first quarter of 2025. We expect to continue generating revenue from these sales ahead of commissioning of our magnet manufacturing capabilities at the Independence Facility, which are targeted to enter service at the end of 2025. As part of our partnership with the DoW, we committed to expand capacity of the Independence Facility to a projected 3,000 MTs of magnets annually and to commence construction of the 10X Facility. Following commissioning of these capabilities and qualification of our finished magnets, we expect to generate revenue primarily from the sale of magnets.

While we have grown increasingly confident about our future outlook with the progress made to-date, there are inherent risks in finalizing construction and developing the process technology for magnet manufacturing. For instance, unforeseen delays in construction or the installation of specific equipment may occur, or our products may fail to satisfy customer expectations, which could adversely affect both the amount and timing of our revenue from permanent magnets and precursor products.

***Our Mineral Reserves***

Our ore body has proven over more than 60 years of operations to be one of the world's largest and highest-grade rare earth resources. As of December 31, 2024, SRK Consulting (U.S.), Inc., an independent consulting firm that we retained to assess our reserves, estimated total proven and probable reserves of 2.04 million short tons of REO contained in 29.69 million short tons of ore at Mountain Pass, with an average ore grade of 5.97%. These estimates use an estimated economical cut-off grade of 2.50% total rare earth oxide. Based on these estimated reserves and our expected annual production rate of REO upon production ramp-up of our midstream operations, our expected mine life was approximately 29 years as of December 31, 2024.

------

<u>[T](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)[able of Contents](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)</u>

Over time, we expect to be able to continue to grow our expected mine life through additional exploratory drilling and improved processing capabilities, which may result in changes to various assumptions underlying our mineral reserve estimate.

Mining activities in the U.S. are heavily regulated, particularly in California. Regulatory changes may make it more challenging for us to access our reserves. In addition, new mineral deposits may be discovered elsewhere, which could make our operations less competitive.

**Key Performance Indicators**

In evaluating the performance of our Materials segment, we use the key performance indicators ("KPIs") outlined below. Our calculations of these KPIs may differ from similar measures published by other companies in our industry or in other industries. See the <u>["Materials Segment"](#i6b490aec1f4c44c2be48633fcd8a3bdf_136)</u> section below for further discussion of year-over-year changes in KPIs. Since the Magnetics segment only recently commenced production, we have not established any KPIs for its operations.

***REO Production Volume***

We measure our REO-equivalent production volume for a given period in MTs, our principal unit of sale for our 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 our upstream operations.

The rare earth concentrate is a processed, concentrated form of our mined rare earth-bearing ores. While our unit of production and sale is a MT of contained REO, the actual weight of our rare earth concentrate is significantly greater, as the concentrate also contains non-REO minerals, loss-on-ignition, and residual moisture from the production process. We target REO content of greater than 60% per dry MT of concentrate (referred to as "REO grade"). The elemental distribution of REO in our concentrate is relatively consistent over time and production lot. We consider this the natural distribution, as it reflects the distribution of elements contained, on average, in our ore.

***REO Sales Volume***

Our REO Sales Volume for a given period is calculated in MTs. A unit, or MT, is considered sold once we recognize revenue on its sale as determined in accordance with generally accepted accounting principles in the United States ("GAAP"). Our REO Sales Volume has historically been a key measure of our ability to convert our concentrate production into revenue. Our REO Sales Volume includes both traditional concentrate as well as roasted concentrate. Given the cessation of shipments of our concentrate as discussed in the <u>["Recent Developments"](#i6b490aec1f4c44c2be48633fcd8a3bdf_124)</u> section above, we do not expect historical REO Sales Volume to be representative of future volumes. Furthermore, we anticipate no longer reporting REO Sales Volume in periods beginning after December 31, 2025.

***Realized Price per REO MT***

We calculate the Realized Price per REO MT for a given period as the quotient of: (i) our rare earth concentrate sales, which are determined in accordance with GAAP, for a given period and (ii) our REO Sales Volume for the same period. Realized Price per REO MT has historically been an important measure of the market price of our concentrate product. Consistent with REO Sales Volume, we anticipate no longer reporting Realized Price per REO MT in periods beginning after December 31, 2025.

***NdPr Production Volume***

We measure our NdPr Production Volume for a given period in MTs, our principal unit of sale for our 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 our midstream operations.

***NdPr Sales Volume***

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

------

<u>[T](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)[able of Contents](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)</u>

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.

For the Materials segment, we have a mix of contracts with customers where we sell NdPr as (i) oxide, (ii) metal, where the amount of oxide required to produce such metal is variable, and (iii) metal, where we have a guarantee of the amount produced and sold based on the amount of oxide consumed. Among other factors, differences between quarterly NdPr Production Volume and NdPr Sales Volume may be caused by the time required for the conversion of NdPr oxide to NdPr metal, including time in-transit, as well as differences in actual versus assumed yields of oxide to metal in the calculation of NdPr Sales Volume.

***NdPr Realized Price per KG***

We calculate the NdPr Realized Price per KG for a given period 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.

***Revenue***

***Rare earth concentrate*** revenue consists of sales of traditional and roasted rare earth concentrate. For the majority of our sales of rare earth concentrate, the sales price is based on a preliminary market price (net of taxes, tariffs, and certain other agreed charges) per MT, with an adjustment for the ultimate market price of the product realized upon final sale, including the impact of changes in exchange rates.

***NdPr oxide and metal*** revenue consists of sales of NdPr oxide and metal produced at Mountain Pass under individual sales agreements, as well as sales under our distribution agreement with Sumitomo Corporation of Americas.

***Magnetic precursor products*** consists of sales of magnetic precursor products, including NdPr metal, produced at the Independence Facility and sold in the U.S. Sales of these products commenced in the first quarter of 2025 pursuant to a long-term supply agreement with GM.

Total revenue increased for the nine months ended September 30, 2025, as compared to the respective prior year period, as a result of ramping production of separated products throughout 2024, resulting in higher NdPr oxide and metal revenue in the current year period. Additionally, during the three and nine months ended September 30, 2025, we began recognizing revenue from the sales of magnetic precursor products, with no comparable revenue in the respective prior year periods. These increases were partially offset by lower rare earth concentrate revenues, resulting in a decrease in total revenue for the three months ended September 30, 2025, driven by the July 2025 cessation of all sales to China as well as by the ramp-up in midstream operations, where a significantly higher portion of REO produced was refined and sold as NdPr oxide and metal during the current year period.

As a result of the items discussed in the <u>["Recent Developments"](#i6b490aec1f4c44c2be48633fcd8a3bdf_124)</u> section above, we expect our rare earth concentrate revenues to be materially lower in future periods as we prioritize further processing the concentrate into separated rare earth products or stockpiling for future use. Similarly, as production of separated rare earth products and magnetic precursor products continues to ramp, we expect revenue from NdPr oxide and metal as well as magnetic precursor products revenue to comprise a growing portion of our total revenue in future periods. See the <u>["Segment Results"](#i08ed632c9d994463a3f5207319fe2ed0_3600)</u> section below for further discussion of year-over-year changes in revenue.

***Cost of sales (excluding depreciation, depletion and amortization)***

Cost of sales (excluding depreciation, depletion and amortization) ("COS") consists of mining, processing, separations, and metal making-related labor costs (including wages and salaries, benefits, bonuses, and stock-based compensation); mining, processing, separations, and metal making-related supplies and reagents; parts and labor for the maintenance of our mining fleet and processing and separating facilities; other facilities-related costs (such as property taxes and utilities); packaging materials; and shipping and freight costs.

| Cost of sales (excluding depreciation, depletion and amortization) | $48477 | $57266 | (15)% | $147739 | $134323 | 10% |

---

The increase in COS for the nine months ended September 30, 2025, was driven by higher sales of NdPr oxide and metal in the current year period, as discussed above, as well as the production costs associated with the magnetic precursor products sold in the current year period, specifically NdPr metal at the Independence Facility, with no comparable costs in the prior year period. These increases were partially offset by a decline in per-unit production costs associated with separated rare earth products as we continue to optimize production, which also drove the decrease in COS for the three months ended September 30, 2025, coupled with overall decreases in total revenue for the three months ended September 30, 2025. Notwithstanding, per-unit production costs of separated products are necessarily higher than those of rare earth concentrate due to the additional processing required. Such costs pertain primarily to chemical reagents, employee labor, maintenance expenses, and consumables.

Lastly, COS for the nine months ended September 30, 2025, benefited from an $8.7 million reduction in reserves in the current year period when compared to prior year period on certain of our work in process and finished goods inventories, as well as a higher Section 45X Advanced Manufacturing Production Credit (the "45X Credit"), which resulted in lower COS of $2.4 million and $7.1 million, for the three and nine months ended September 30, 2025, respectively.

As we produce and sell more separated products at Mountain Pass, we expect that COS may continue to increase throughout 2025 even as certain per-unit production efficiencies and economies of scale are expected to be achieved, primarily due to the higher production costs associated with separated rare earth products versus rare earth concentrate, as discussed

above. Accordingly, in future periods, any further increase in sales of NdPr oxide and metal will likely result in higher year-over-year COS. Additionally, should we further ramp the production of magnetic precursor products at Independence, COS may also increase.

***Selling, general and administrative***

Selling, general and administrative ("SG&A") expenses consist primarily of personnel costs (including salaries, benefits, bonuses, and stock-based compensation) of our administrative functions such as executives, accounting and finance, legal, and information technology; professional services (including legal, regulatory, audit and others); certain engineering expenses; insurance, license and permit costs; corporate office lease cost; office supplies; and certain environmental, health and safety expenses.

| Selling, general and administrative | $28405 | $21525 | 32% | $80000 | $64226 | 25% |

---

The increases in SG&A expenses for the three and nine months ended September 30, 2025, as compared to the respective prior year periods, were driven primarily by higher legal costs, which increased by $2.5 million and $7.8 million for the three and nine months ended September 30, 2025, respectively. Additionally, higher personnel costs (excluding stock-based compensation expense) contributed $1.2 million and $4.6 million, respectively, of the increase in the current respective year periods, due to increased employee headcount to support our downstream expansion.

***Depreciation, depletion and amortization***

Depreciation, depletion and amortization ("DD&A") primarily consists of depreciation of property, plant and equipment and depletion of mineral rights.

| | **For the three months ended September 30,** | **For the three months ended September 30,** | **Change** | **For the nine months ended September 30,** | **For the nine months ended September 30,** | **Change** |
| ***(in thousands, except percentages)*** | **2025** | **2024** | $**%** | **2025** | **2024** | $**%** |
| Depreciation, depletion and amortization | $22497 | $19344 | 16% | $64658 | $55939 | 16% |

---

The year-over-year increases in DD&A for the three and nine months ended September 30, 2025, primarily reflect increases in depreciation of $2.5 million and $9.7 million, respectively. Depreciation increased as a result of the timing of placing certain machinery and equipment assets into service, which occurred progressively throughout 2024, with the majority placed into service during the fourth quarter of 2024 as we began production of magnetic precursor products at Independence.

Beginning in the fourth quarter of 2025, DD&A will include amortization of the right to the price floor protection granted by the DoW under the PPA.

***Start-up costs***

Start-up costs relate to costs associated with restarting an existing facility or commissioning a new facility, circuit or process of our production, manufacturing, or separations facilities prior to the achievement of commercial production, that do not qualify for capitalization. Such costs, which are expensed as incurred, include certain salaries and wages, outside services, parts, training, and utilities, among other items, used or consumed directly in these start-up activities.

| Start-up costs | $1413 | $1627 | (13)% | $3150 | $4287 | (27)% |

---

The year-over-year decreases in start-up costs for three and nine months ended September 30, 2025, were attributable primarily to our downstream initiatives, where start-up activities have declined in line with the commencement of our production of magnetic precursor products at Independence in late 2024.

| Advanced projects and development | $19026 | $2051 | 828% | $21996 | $8143 | 170% |

---

The year-over-year increases in advanced projects and development for the three and nine months ended September 30, 2025, were primarily due to higher transaction costs, largely associated with the transactions described in the <u>["Recent Developments"](#i6b490aec1f4c44c2be48633fcd8a3bdf_124)</u> section above, including $7.4 million of transaction costs incurred to secure financing and $12.4 million of transaction costs incurred in association with the DoW Transactions.

***Other operating costs and expenses (income), net***

Other operating costs and expenses (income), net consists primarily of accretion of asset retirement and environmental obligations and gains or losses on disposals of long-lived assets, including demolition costs.

---

The year-over-year changes were attributed primarily to the net impact of gains recognized on sales of certain long-lived assets during the three and nine months ended September 30, 2025.

***Interest expense, net***

Interest expense, net principally consists of the expense associated with the 0.25% and 3.00% per annum interest rates and amortization of the debt issuance costs on our 2026 Notes and 2030 Notes (as defined below), respectively, as well as interest expense associated with the Samarium Project Loan, offset by capitalized interest.

| Interest expense, net | $8566 | $6646 | 29% | $21595 | $16248 | 33% |

---

Interest expense, net for the three and nine months ended September 30, 2025, increased year over year primarily due to the interest expense associated with the issuance of the Samarium Project Loan in August 2025 and the 2030 Notes in March and December 2024, partially offset by repurchases of the 2026 Notes in 2024 and by higher capitalized interest in the current year period.

---

Gain on early extinguishment of debt during the nine months ended September 30, 2024, was the result of the repurchase of a portion of our 2026 Notes at prices lower than the associated carrying amounts. See the <u>["Liquidity and Capital Resources"](#i6b490aec1f4c44c2be48633fcd8a3bdf_148)</u> section below for additional information.

| Other income, net | $17157 | $11320 | 52% | $38947 | $36061 | 8% |

---

Other income, net for the three and nine months ended September 30, 2025, increased year over year primarily as a result of higher interest and investment income earned on our short-term investments during the three months ended September 30, 2025, whose balance increased in the third quarter of 2025. Interest and investment income is principally generated from accretion of the discount on such investments. Additionally, other income, net was impacted by the changes in the fair value of the derivative instrument related to the redemption feature included in the portion of the 2030 Notes issued in December 2024, which was a $1.1 million loss and a $3.4 million gain for the three and nine months ended September 30, 2025, respectively. Finally, the nine months ended September 30, 2025, benefited from a gain of $1.3 million related to the disposition of the VREX Holdco equity method investment.

***Income tax benefit***

Income tax expense or benefit consists of an estimate of U.S. federal and state income taxes in the jurisdictions in which we conduct business, adjusted for federal, state and local allowable income tax benefits, the effect of permanent differences and any valuation allowance against deferred tax assets.

---

The effective tax rate for the three and nine months ended September 30, 2025, differed from the statutory tax rate of 21% primarily due to the 45X Credit, percentage depletion, and state income tax benefit, offset by a deduction limitation on officers' compensation and a valuation allowance on California Competes Tax Credits ("CCTC"). The effective tax rate for the three and nine months ended September 30, 2024, differed from the statutory tax rate of 21% primarily due to state income tax expense and a deduction limitation on officers' compensation, offset by the 45X Credit and CCTC.

The year-over-year decreases in rare earth concentrate revenue for the three and nine months ended September 30, 2025, were primarily driven by the decreases in REO Sales Volume impacted by the July 2025 cessation of all sales to China as well as the ramp-up in midstream operations, where a significantly higher portion of REO produced was refined and sold as NdPr oxide and metal during the current year period. As noted above in the <u>["Factors Affecting our Performance"](#i6b490aec1f4c44c2be48633fcd8a3bdf_127)</u> section, market prices for rare earth products may be volatile due to actual or perceived changes in supply or demand.

Until we commenced our midstream operations, our REO Sales Volume generally tracked our REO Production Volume over time with slight period-to-period differences caused by the timing of shipments. However, as a result of the items discussed in the <u>["Recent Developments"](#i6b490aec1f4c44c2be48633fcd8a3bdf_124)</u> section above and as we continue to ramp up production of separated rare earth materials, we expect that significant volumes of REO produced from upstream operations will continue to be consumed for separation or stockpiled for future use. In addition, a significant portion of the contained cerium in the REO produced will be intentionally rejected and may not result in finished product. Accordingly, we expect our rare earth concentrate revenues, if any, to be materially lower in future periods.

The increases in NdPr oxide and metal revenue for the three and nine months ended September 30, 2025, as compared to the respective prior year periods, were primarily driven by higher NdPr Production Volume as a result of ramping production of separated products throughout the prior year periods. NdPr oxide and metal revenue for the three and nine months ended September 30, 2025, also benefited from higher NdPr Realized Price per KG as compared to the prior year period. We expect to begin intersegment sales of NdPr oxide to the Magnetics segment in the fourth quarter of 2025.

The decreases in Materials Segment Adjusted EBITDA for the three and nine months ended September 30, 2025, when compared to the respective prior year periods, were driven primarily by the net decreases in revenue, as discussed above, partially offset by corresponding decreases in cost of sales (excluding depreciation, depletion and amortization and stock-based compensation expense) ("Segment COS"), although the decreases in Segment COS were negatively impacted by higher per-unit production costs of separated products rare earth products sold in the current year period, compared to those of rare earth concentrate. Segment COS for the nine months ended September 30, 2025, also benefited from an $8.7 million reduction in reserves on certain of our work in process and finished goods inventories in the current year period, as well as a higher 45X Credit, which resulted in lower Segment COS of $2.4 million and $7.1 million for the three and nine months ended September 30, 2025, respectively.

As discussed in the <u>["Recent Developments"](#i6b490aec1f4c44c2be48633fcd8a3bdf_124)</u> section above, the PPA for our NdPr products commences on October 1, 2025; given current market prices for NdPr products, we expect to have the right to receive cash from the DoW and recognize income under the PPA starting in the fourth quarter of 2025, which we expect will have a significant impact on the operating results of the Materials segment.

***Magnetics Segment***

The Magnetics segment operates the Independence Facility, where we produce and sell magnetic precursor products and anticipate the manufacturing of NdFeB permanent magnets by the end of 2025.

We began generating revenue from sales of magnetic precursor products during the first quarter 2025, with no comparable sales during the prior year periods (see <u>[Note](#i6b490aec1f4c44c2be48633fcd8a3bdf_79)</u><u>16</u><u>[, "Revenue Recognition,](#i6b490aec1f4c44c2be48633fcd8a3bdf_79)</u><u>["](#i6b490aec1f4c44c2be48633fcd8a3bdf_79)</u> in the notes to the unaudited Condensed Consolidated Financial Statements for additional information), which also drove the year-over-year increase in Magnetics Segment Adjusted EBITDA. We continue to expect that the historical trend of Magnetics Segment Adjusted EBITDA will be impacted by the production of magnetic precursor products.

**Corporate Expenses and Other**

Corporate expenses and other is primarily comprised of the operating results of other business activities that excludes our Materials and Magnetics segments and includes costs incurred at the corporate level that are not allocated to the operating segments, specifically relating to executive compensation, investor relations, other corporate costs, and unallocated shared service functions such as legal, information technology, human resources, finance and accounting and supply chain. Corporate expenses and other excludes stock-based compensation expense.

The increases in corporate expenses and other for the three and nine months ended September 30, 2025, as compared to the respective prior year periods, were driven primarily by higher personnel costs (other than stock-based compensation expense) related to executives and administrative personnel, as well as expenses related to corporate air travel and security services.

**Liquidity and Capital Resources**

Liquidity refers to our ability to generate sufficient cash flows to meet the cash requirements of our business operations, including working capital and capital expenditure needs, contractual obligations, debt service and other commitments. In addition to net cash from operating activities, our principal sources of liquidity have been issuances of long-term debt and offerings of shares of our common stock and Series A Preferred Stock. As of September 30, 2025, we had $1,940.4 million of cash, cash equivalents and short-term investments and $1,105.7 million of principal amount of long-term debt and equipment notes, including $71.5 million classified as current.

Historically, our results of operations and cash flows have depended in large part upon the market prices of rare earth products. Rare earth concentrate is not quoted on any major commodities market or exchange and demand is currently constrained to a relatively limited number of refiners, a significant majority of which are based in China. Uncertainty exists as to the market price of rare earth products primarily due to actual or perceived concerns over increases in the supply of and/or decreases in demand for rare earth products as well as global economic conditions. For example, the significant decrease in the market price of rare earth products in 2024 negatively impacted our cash flows from operations and liquidity.

The cessation of shipments to China had, at least in the short-term, a material negative impact on our results of operations and cash flows. However, we expect this negative impact to be significantly reduced beginning in the fourth quarter of 2025 once the Price Protection Agreement is effective and starts to provide us with pricing stability. We believe that our cash flows from operations and cash on hand are adequate to meet our liquidity requirements for the foreseeable future. Specifically, as part of the DoW Transactions, we received significant cash investments and future commitments from the DoW, and in July 2025, we also received a prepayment commitment from Apple, while raising $724.2 million in net proceeds in the Offering. See the <u>["Recent Developments"](#i6b490aec1f4c44c2be48633fcd8a3bdf_124)</u> section for additional information.

While the DoW Transactions, together with our supply agreements with Apple and GM, provide a measure of certainty with respect to both near- and longer-term demand for our products and related revenues, significant factors remain, which could negatively impact our liquidity, particularly in the longer-term, many of which remain largely uncertain and dependent on future developments that cannot be accurately predicted at this time, such as: our ability to accelerate our downstream operations and expansion, achieve our business milestones, and perform the obligations under our customer supply agreements, as well as further changes in trade policies in the United States, China or other countries, including the implementation of new tariffs, increases in or reductions of existing tariffs, or the taking of other actions.

Our current working capital needs relate mainly to our mining, beneficiation, and separation operations. Our working capital needs have increased materially as we have ramped up the production and sales of separated rare earth products. Additionally, they have also increased as a result of the DoW Transactions and our agreement with Apple, and we expect those needs may continue to see further increases in 2025 and 2026 as we continue to scale production of separated rare earth products and advance our downstream magnetics initiatives, including the production and sales of magnetic precursor products and the commissioning of our magnet manufacturing capabilities, as well as a build up of raw materials and parts necessary to support these initiatives.

The completion of our mission to become a fully integrated domestic magnetics producer is expected to be capital intensive. Our principal capital expenditure requirements relate mainly to further investment in Mountain Pass, including the development of the HREE Facility, Upstream 60K, and other growth and investment projects, completing the buildout of Independence, as well as periodic repairs and maintenance of mining and rare earth processing equipment. Prior to the consideration of capital expenditures related to our July 2025 announcements, we expect to spend between $150 million and $175 million of capital costs in 2025 (net of any proceeds from government awards received). Our future capital requirements will also depend on several other factors, including market conditions, de-bottlenecking initiatives, decisions regarding downstream production capability, and potential acquisitions.

Our estimated costs or estimated time to complete and commission these projects may increase, potentially significantly, due to factors outside of our control. While we believe that we have sufficient cash resources to fund these initiatives and operating working capital in the near term, we cannot assure this. If our available resources prove inadequate to fund our plans or commitments, we may be forced to revise our strategy and business plans or could be required, or elect, to seek additional funding through public or private equity or debt financings; however, such funding may not be available on terms acceptable to us, if at all. Any delays in our ongoing capital projects or substantial cost increases, including construction costs and related materials costs related to their execution, could significantly impact our ability to maximize our revenue opportunities and adversely impact our business and cash flows.

***Debt and Other Long-Term Obligations***

***Revolving Credit Facility:*** In August 2025, we entered into a credit agreement with JPMorgan Chase Bank, N.A. as administrative agent, and various other lenders, providing a $275.0 million revolving credit facility (the "Revolving Credit Facility"), maturing on August 25, 2030, with a $200.0 million letter of credit facility sublimit (the "Credit Agreement"). As of September 30, 2025, we had no outstanding borrowings under the Revolving Credit Facility, $160.0 million of unused letter of credit capacity, and $235.0 million of remaining borrowing capacity under the Revolving Credit Facility.

Interest rates under the Revolving Credit Facility are variable based on the Secured Overnight Financing Rate ("SOFR"), or at our option, at a base reference rate equal to the highest of (i) the federal funds rate plus 0.50%, (ii) the rate of interest last quoted by The Wall Street Journal as the "prime rate" in the U.S., (iii) the one-month SOFR rate plus 1.00% o (iv) 1.00% (the "Base Rate"), plus, as applicable, a margin ranging from 1.75% to 2.50% per annum for SOFR-based loans and ranging from 0.75% to 1.50% per annum for Base Rate-based loans, in each case, depending on our total leverage ratio.

The Credit Agreement is subject to financial covenants that are tested at the end of each fiscal quarter. From the inception of the Credit Agreement until the earlier of the fiscal quarter in which our consolidated EBITDA (as calculated and defined in the Credit Agreement) equals or exceeds $400.0 million for the test period and the fiscal quarter ending June 30, 2027 (the "Covenant Trigger Event"), we must maintain unrestricted cash and cash equivalents of at least $500.0 million. Following the Covenant Trigger Event, we are required to maintain a total leverage ratio of less than 4.00:1.00, or 4.50:1.00 for the fiscal quarter of and the three consecutive fiscal quarters following any material acquisition, and a cash interest coverage ratio greater than 3.0:1.0.

The Credit Agreement is guaranteed by us and our subsidiaries, subject to certain customary exceptions. Failure to comply with any of the covenants associated with the Credit Agreement could result in a default under its agreements. Such a default would permit lenders to accelerate the maturity of the debt and to foreclose upon any collateral securing such debt. We are in compliance with the applicable financial covenant contained in the Credit Agreement as of September 30, 2025.

***2026 Notes:*** In March 2021, we issued $690.0 million in aggregate principal amount of 0.25% unsecured convertible senior notes (the "2026 Notes") at a price of par. Interest on the 2026 Notes is payable on April 1<sup>st</sup> and October 1<sup>st</sup> of each year, beginning on October 1, 2021.

In March 2024, contemporaneous with the pricing of the 2030 Notes (as defined below), we entered into privately negotiated transactions with certain holders of the 2026 Notes to repurchase $400.0 million in aggregate principal amount of the 2026 Notes, using $358.0 million of the net proceeds from the offering of the 2030 Notes. The price we paid to repurchase the 2026 Notes, 89.5% of par value, was the same for each lender and approximated the trading price of the 2026 Notes at the time of the repurchases. Subsequent to the issuance of the 2030 Notes, we repurchased an additional $80.0 million in aggregate principal amount of the 2026 Notes in open market transactions for $70.6 million. As a result of these repurchases, we recorded a $46.3 million gain on early extinguishment of debt in the first quarter of 2024.

The remaining 2026 Notes outstanding mature, unless earlier converted, redeemed or repurchased, on April 1, 2026, and become convertible at the option of the holder beginning on January 1, 2026, through the business day immediately preceding the maturity date. The initial conversion price of the remaining 2026 Notes is approximately $44.28 per share, or 22.5861 shares per $1,000 principal amount of notes, subject to adjustment upon the occurrence of certain events.

In March 2024, we provided a written notice to the trustee and the holders of the 2026 Notes that we have irrevocably elected to fix the settlement method for all conversions that may occur subsequent to the election date, to a combination of cash and shares of our common stock with the specified dollar amount per $1,000 principal amount of the 2026 Notes of $1,000. As a result, for any conversions of 2026 Notes occurring after the election date, a converting holder will receive (i) up to $1,000 in cash per $1,000 principal amount of the 2026 Notes and (ii) shares of our common stock for any conversion consideration in excess of $1,000 per $1,000 principal amount of the 2026 Notes converted. Prior to the election being made, we could have elected to settle the 2026 Notes in cash, shares of our common stock or a combination thereof.

Prior to January 1, 2026, at their election, holders of the 2026 Notes may convert their outstanding notes under the following circumstances: (i) during any calendar quarter commencing with the third quarter of 2021 if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (ii) during the five business day period after any five consecutive trading day period (the "2026 Notes measurement period") in which the trading price (as defined in the indenture governing the 2026 Notes) per $1,000 principal amount of 2026 Notes for each trading day of the 2026 Notes measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day;

(iii) if we call any or all of the 2026 Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or (iv) upon the occurrence of specified corporate events set forth in the indenture governing the 2026 Notes.

During the third quarter of 2025, the closing price of our common stock exceeded the 130% of the applicable conversion price on at least 20 of the last 30 consecutive trading days, causing the 2026 Notes to be convertible by their holders in the fourth quarter of 2025.

***2030 Notes:*** In March 2024, we issued $747.5 million in aggregate principal amount of 3.00% unsecured convertible senior notes that mature, unless earlier converted, redeemed or repurchased, on March 1, 2030 (the "2030 Notes" and, together with the 2026 Notes, the "Convertible Notes"), at a price of par. Interest on the 2030 Notes is payable on March 1<sup>st</sup> and September 1<sup>st</sup> of each year, beginning on September 1, 2024.

The 2030 Notes are convertible into cash, shares of our common stock or a combination thereof, at our election, at an initial conversion price of approximately $21.74 per share, or 45.9939 shares per $1,000 principal amount of 2030 Notes, subject to adjustment upon the occurrence of certain events.

Prior to December 1, 2029, at their election, holders of the 2030 Notes may convert their outstanding notes under the following circumstances: i) during any calendar quarter commencing with the third quarter of 2024 if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; ii) during the five business day period after any ten consecutive trading day period (the "2030 Notes measurement period") in which the trading price (as defined in the indenture governing the 2030 Notes) per $1,000 principal amount of 2030 Notes for each trading day of the 2030 Notes measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; iii) if we call any or all of the 2030 Notes for redemption, the notes called for redemption may be converted at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or iv) upon the occurrence of specified corporate events set forth in the indenture governing the 2030 Notes. On or after December 1, 2029, and prior to the close of business on the second scheduled trading day immediately preceding the maturity date of the 2030 Notes, holders may convert their outstanding notes at any time, regardless of the foregoing circumstances.

During the third quarter of 2025, the closing price our common stock exceeded the 130% of the applicable conversion price on at least 20 of the last 30 consecutive trading days, causing the 2030 Notes to be convertible by their holders in the fourth quarter of 2025. As noted above, the settlement method of the 2030 Notes is at our election.

We have the option to redeem for cash the 2030 Notes, in whole or in part, beginning on March 5, 2027, if certain conditions are met as set forth in the indenture governing the 2030 Notes. The redemption price is equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest.

***Capped Call Options:*** In March 2024, in connection with the offering of the 2030 Notes, we entered into privately negotiated capped call transactions (the "Capped Call Options") with certain financial institutions ("Counterparties"). The Capped Call Options cover, subject to anti-dilution adjustments substantially similar to those in the 2030 Notes, 34.4 million shares of our common stock, the same number of shares that initially underlie the 2030 Notes issued in March 2024. The Capped Call Options have an expiration date of March 1, 2030, subject to earlier exercise.

The Capped Call Options are intended, subject to our discretion and depending on whether we elect to exercise our rights under such options, to reduce the potential dilution to our common stock upon conversion of the 2030 Notes and/or offset cash payments we are required to make in excess of the principal amount of the converted 2030 Notes, as the case may be. This would apply in the event that the market price per share of our common stock, as measured under the terms of the Capped Call Options, is greater than the strike price of the Capped Call Options, which initially corresponds to the initial conversion price of the 2030 Notes, or approximately $21.74 per share of common stock, with such reduction and/or offset subject to an initial cap of $31.06 per share of our common stock.

The Capped Call Options are separate transactions, entered into by the Company with each of the Counterparties, and are not part of the terms of the 2030 Notes. Holders of the 2030 Notes do not have any rights with respect to the Capped Call Options. We paid $65.3 million for the Capped Call Options in March 2024.

***Samarium Project Loan:*** In August 2025, we issued a $150 million unsecured promissory note to the DoW with a 12-year term, maturing on August 1, 2037. The Samarium Project Loan bears interest at a rate of 5.38% per annum, calculated as the 10-year U.S. Treasury constant maturity rate plus 1.00%. Interest on the Samarium Project Loan is payable in cash quarterly in

arrears on the 15th day of each calendar quarter, beginning on October 15, 2025. We may prepay the Samarium Project Loan, in whole or in part, at any time, including all accrued interest, without premium, cost or penalty. The outstanding principal and all accrued and unpaid interest under the Samarium Project Loan become immediately due and payable upon the occurrence of certain conditions, such as payment defaults, as specified in the promissory note to the DoW.

***Equipment Notes:*** In December 2024, we entered into a secured uncommitted non-revolving credit facility (the "Uncommitted Credit Facility") with Caterpillar Financial Services Corporation, providing an aggregate borrowing capacity of $25.0 million, which we may use only to finance agreed-upon equipment. During the nine months ended September 30, 2025, we executed promissory notes under the Uncommitted Credit Facility to finance new equipment, including trucks and wheel loaders, for use at Mountain Pass. As of September 30, 2025, we had no available borrowing capacity under the Uncommitted Credit Facility. Our equipment notes, which are secured by the purchased equipment, had $25.2 million in principal (and accrued interest) outstanding as of September 30, 2025.

***Leases:*** We have lease arrangements for certain equipment and facilities, including office space, warehouses, and equipment used in our operations. As of September 30, 2025, we had future expected lease payment obligations totaling $15.1 million, with $4.2 million due within the next 12 months.

***Share Repurchase Programs***

In March 2024, our Board of Directors approved a share repurchase program (the "Program") effective for one year under which the Company became authorized to repurchase up to an aggregate amount of $300.0 million of our outstanding common stock. In August 2024, our Board of Directors approved a $300.0 million increase to the Program, bringing the total authorized amount to $600.0 million. The authorization did not require the purchase of any minimum number of shares. On July 11, 2025, pursuant to the terms of the DoW Transaction Agreements, we terminated the Program, which would have otherwise continued until August 30, 2026.

***Cash Flows***

N/M = Not meaningful.

***Net Cash Used in Operating Activities:*** Net cash used in operating activities increased by $91.8 million for the nine months ended September 30, 2025, as compared to the prior year period, driven primarily by the increase in inventories, including stockpiled concentrate, to support the ramp of production of separated products and magnetic precursor products. Additionally, in the prior year period, we received $19.4 million related to the 45X Credit claimed on our 2023 federal tax return.

***Net Cash Provided by (Used in) Investing Activities:*** Net cash used in investing activities was $279.1 million for the nine months ended September 30, 2025, as compared to the net cash provided by investing activities of $31.7 million in the prior year period. The change in cash flows from investing activities was primarily driven by lower net proceeds from sales and maturities of short-term investments in the current year period, resulting in a net decrease in cash provided of $383.4 million. This was partially offset by lower additions to property, plant and equipment for the nine months ended September 30, 2025,

which decreased by $58.9 million when compared to the prior year period, and related primarily to a decrease in construction spend on certain projects, such as the separations facility for heavy rare earth elements, as well as $24.2 million in proceeds from government awards used for construction that we received during the nine months ended September 30, 2025. Additionally, we also received $9.7 million in the current year period in exchange for the sale of our 49% interest in VREX Holdco.

***Net Cash Provided by Financing Activities:*** Net cash provided by financing activities increased by $1.2 billion for the nine months ended September 30, 2025, as compared to the prior year period, driven primarily by the net cash proceeds of $1.3 billion received from the Offering and the DoW Transactions. The prior year period included the net cash flow impact of $12.4 million from the issuance of the 2030 Notes, the payments of debt issuance costs associated with the 2030 Notes, the payments made to retire a significant portion of the 2026 Notes, the purchase of the Capped Call Options, and the payments made to repurchase our common stock.

**Non-GAAP Financial Measures**

We present Adjusted EBITDA, Adjusted Net Loss, Adjusted Diluted EPS, and Free Cash Flow, which are non-GAAP financial measures that we use to supplement our results presented in accordance with GAAP. These measures may be similar to measures reported by other companies in our industry and are regularly used by securities analysts and investors to measure companies' financial performance. Adjusted EBITDA, Adjusted Net Loss, Adjusted Diluted EPS, and Free Cash Flow are not intended to be substitutes for any GAAP financial measures and, as calculated, may not be comparable to other similarly titled measures of performance or liquidity of other companies within our industry or in other industries.

***Adjusted EBITDA***

We define Adjusted EBITDA as our 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 we do not consider representative of our underlying operations. We present Adjusted EBITDA because it is used by management to evaluate our underlying operating and financial performance and trends. Adjusted EBITDA excludes certain expenses that are required in accordance with GAAP because they are non-recurring, non-cash or are not related to our underlying business performance. This non-GAAP financial measure is intended to supplement our GAAP results and should not be used as a substitute for financial measures presented in accordance with GAAP.

The following table presents a reconciliation of our Adjusted EBITDA, which is a non-GAAP financial measure, to our net income or loss, which is determined in accordance with GAAP:

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.

***Adjusted Net Loss and Adjusted Diluted EPS***

We calculate Adjusted Net Loss as our 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 we do not consider representative of our underlying operations; adjusted to give effect to the income tax impact of such adjustments. We calculate Adjusted Diluted EPS as our 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 we do 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 share and Adjusted Diluted EPS.

Adjusted Net Loss and Adjusted Diluted EPS exclude certain expenses that are required in accordance with GAAP because they are non-recurring, non-cash, or not related to our underlying business performance. To calculate the income tax impact of such adjustments on a year-to-date basis, we utilize an effective tax rate equal to our income tax expense or benefit excluding material discrete costs and benefits, with any impacts of changes in effective tax rate being recognized in the current period. We present Adjusted Net Loss and Adjusted Diluted EPS because it is used by management to evaluate our underlying operating and financial performance and trends. These non-GAAP financial measures are intended to supplement our GAAP results and should not be used as a substitute for financial measures presented in accordance with GAAP.

***Free Cash Flow***

We calculate Free Cash Flow as net cash provided by or used in operating activities less additions to property, plant and equipment, net of proceeds from government awards used for construction. We believe Free Cash Flow is useful for comparing our ability to generate cash with that of our peers. The presentation of Free Cash Flow is not meant to be considered in isolation or as an alternative to cash flows from operating activities and does not necessarily indicate whether cash flows will be sufficient to fund cash needs.

There have been no material changes in our market risk exposures from the information presented in <u>[Part II, Item 7A. "Quantitative and Qualitative Disclosures About Market Risk,"](https://www.sec.gov/Archives/edgar/data/1801368/000180136825000009/mp-20241231.htm#iadaf5f13b1c64f46a9f722e1c17671e4_148)</u> in our Annual Report on Form 10-K for the year ended December 31, 2024, except as disclosed below.

***Commodity Price Risk***

Our results of operations have historically depended in large part upon the market prices of REO and particularly the price of rare earth concentrate and NdPr. Rare earth concentrate is not quoted on any major commodities market or exchange as product attributes vary and demand is currently constrained to a relatively limited number of refiners, a significant majority of which are based in China. NdPr pricing is primarily based off of indices in China.

NdPr represents a significant portion of the economic value of our rare earth concentrate. We expect demand for NdPr to continue to grow, driving demand for our separated NdPr oxide and metal, and in the future, permanent magnets containing NdPr. However, actual demand and pricing may fluctuate for numerous reasons beyond our control, including, among other things, supply of NdPr from other producers, discoveries of new mineral properties, technological changes that lead to diminished reliance on NdPr and/or permanent magnets, and shifts in underlying end-user demand for products or components manufactured with NdPr.

The Company's arrangements with the DoW will significantly mitigate the risks of commodity price fluctuations associated with NdPr on our results of operations. Among the transactions with the DoW, the Company entered the Price Protection Agreement, which provides a price floor of $110 per KG for NdPr products stockpiled, sold to internal affiliates, or sold to third parties. If market prices fall below this threshold, the Company will receive a quarterly payment from the DoW to offset the shortfall. Conversely, once the 10X Facility reaches full production capacity, if the price of NdPr exceeds the threshold, the Company will remit a portion of the upside to the DoW, equal to 30% of the NdPr sales price in excess of $110 per KG. This arrangement allows the Company to produce NdPr at a more stable price, with limited exposure to price declines while retaining upside exposure. This moderates the Company's exposure to the fluctuations in the NdPr commodity market which the Company has experienced in recent years.

Additionally, the DoW agreed to purchase the entire quantity of magnets produced at the 10X Facility, which, upon completion, we expect will utilize as an input a substantial portion of the NdPr we produce. While this DoW commitment provides a meaningful measure of certainty with respect to our medium- and longer-term NdPr-related cash flows, our business remains susceptible to the fluctuations and uncertainties described above, particularly with respect to the volume of demand for our NdPr products prior to the completion of the 10X Facility when the DoW offtake commitment begins. Thereafter, our business will still remain susceptible to demand fluctuations for amounts other than those used in committed arrangements in

<u>[T](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)[able of Contents](#i6b490aec1f4c44c2be48633fcd8a3bdf_7)</u>

our Magnetics segment (including both Independence and the 10X Facility). Additionally, we continue to produce other rare earth products, which is required by the DoW Transaction Agreements to include samarium, which will remain and be subject to market pricing.

The solvent extraction and finishing processes are highly reliant upon commodity reagents. These reagents, as well as certain other raw materials and supplies we use in our operations, are subject to price volatility caused by weather, supply conditions, political and economic variables and other unpredictable factors. We have not historically used options or swap contracts to manage the volatility related to the above exposures. When possible, we seek to limit our exposure by entering into long-term contracts and price increase limitations in contracts. Also, we use natural gas to operate our CHP plant, which powers our processing and separations facilities at Mountain Pass, and to power backup generators at the Independence Facility. We generally purchase or expect to purchase natural gas from suppliers at market or tariff rates. From time to time, we use commodity contracts to hedge energy exposures. Such commodity price fluctuations may cause volatility in our results of operations and cash flows in the future.

***Foreign Currency Risk***

While we currently generate revenue in the United States and in U.S. dollars, the market transactions are denominated mainly in the Chinese Yuan, and we are therefore exposed to currency volatility and devaluation risks. For example, we have historically negotiated quarterly U.S. dollar prices with our customers, which were based in part on the exchange rate between the U.S. dollar and the Chinese Yuan. This exchange rate has been impacted by geopolitical tensions between the U.S. and China, which has and may lead to increased tariffs in the future, preferences for local producers, some of which may be government-supported, changes in taxing regimes or other trade barriers. Foreign currency risk has not historically had a material impact on our results of operations or cash flows.

Our partnership with the DoW, including with respect to the Price Protection Agreement for our NdPr products and purchase commitment of 10X Facility-produced magnets, should help to further mitigate our exposure to this volatility and risk over time, assuring us of substantial cash flows in U.S. dollars. We are in the process of evaluating the continuing need for the negotiation of Yuan-specific protections given this and other recent developments in our business and the market broadly. However, our non-NdPr rare earth products, including samarium, as well as inputs used throughout our processes, remain exposed to market transactions denominated primarily in Chinese Yuan, as may the price of NdPr-based magnets and magnet products produced at our Independence Facility. Additionally, as we expand internationally, we become further exposed to foreign currency risk by entering new markets with additional foreign currencies. The economic impact of currency exchange rate movements is often linked to variability in real growth, inflation, interest rates, governmental actions and other factors. Accordingly, to the extent that foreign currency risk becomes material, we may enter into hedging transactions to manage our exposure to fluctuations in foreign currency exchange rates.

## Exhibit 95.1

**Exhibit 95.1**

**MINE SAFETY DISCLOSURE**

Pursuant to Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act"), issuers that are operators, or that have a subsidiary that is an operator, of a coal or other mine in the United States are required to disclose in their periodic reports filed with the SEC information regarding specified health and safety violations, orders and citations, issued under the Federal Mine Safety and Health Act of 1977 (the "Mine Act") by the Mine Safety and Health Administration (the "MSHA"), as well as related assessments and legal actions, and mining-related fatalities.

The table below provides information for the three months ended September 30, 2025, at the Mountain Pass mine in San Bernardino County, California.

Additional information about the Mine Act and MSHA references used in the table follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Section 104(a) Significant and Substantial ("S&S") Citations:* Citations received from MSHA under §104(a) of the Mine Act for violations of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a mine safety or health hazard.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Section 104(b) Orders:* Orders issued by MSHA under §104(b) of the Mine Act, which represent a failure to abate a citation under §104(a) within the period of time prescribed by MSHA. This results in an order of immediate withdrawal from the area of the mine affected by the condition until MSHA determines that the violation has been abated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Section 104(d) S&S Citations and Orders:* Citations and orders issued by MSHA under §104(d) of the Mine Act for unwarrantable failure to comply with mandatory, significant and substantial health or safety standards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Section 110(b)(2) Violations:* Flagrant violations issued by MSHA under §110(b)(2) of the Mine Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Section 107(a) Orders:* Orders issued by MSHA under §107(a) of the Mine Act for situations in which MSHA determined an "imminent danger" (as defined by MSHA) existed.
