**CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS**

Certain statements included in this Quarterly Report on Form 10-Q for the three months ended June 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 DoD Transactions (as defined in <u>[Note](#i36e728074715429b91883a0ff85e6f7d_103)</u> <u>22[, "Subsequent Events"](#i36e728074715429b91883a0ff85e6f7d_103)</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 DoD 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 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;• 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"](#i36e728074715429b91883a0ff85e6f7d_106)</u> and <u>[Part II, Item 1A, "Risk Factors"](#i36e728074715429b91883a0ff85e6f7d_169)</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"](#i36e728074715429b91883a0ff85e6f7d_169)</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. 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](#i36e728074715429b91883a0ff85e6f7d_97)20[, "Segment Reporting,"](#i36e728074715429b91883a0ff85e6f7d_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](#i36e728074715429b91883a0ff85e6f7d_94)</u><u>19</u><u>[, "Related-Party Transactions"](#i36e728074715429b91883a0ff85e6f7d_94)</u>), that, in turn, typically sold such product to refiners in China. In April 2025, in response to China's retaliatory tariffs and export controls, the Company made the strategic decision to cease shipments of rare earth concentrate to China. In July 2025, to align with the terms of the DoD Transaction Agreements (as defined in <u>[Note](#i36e728074715429b91883a0ff85e6f7d_103)</u><u>22[, "Subsequent Events"](#i36e728074715429b91883a0ff85e6f7d_103)</u>) and in further support of its domestic supply chain objectives, the Company agreed to cease all future sales of its products to China and determined it would not exercise its right to extend the term of the Shenghe Offtake Agreement when it expires in January 2026.

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 10, 2025, the Company announced a public-private partnership with the United States Department of Defense (the "DoD"), as further described in <u>[Note](#i36e728074715429b91883a0ff85e6f7d_103)</u><u>22[, "Subsequent Events."](#i36e728074715429b91883a0ff85e6f7d_103)</u> Under the terms of the agreements with the DoD, the Company will expand its Independence Facility and construct a second domestic magnet manufacturing facility (the "10X Facility"), accelerate and expand its heavy rare earth elements ("HREE") refining capacity at Mountain Pass, and undertake several other growth initiatives. These commitments are underpinned by the long-term agreements with the DoD, including the purchase in full of all magnets produced at the 10X Facility with a minimum facility EBITDA (as defined in the offtake agreement with the DoD), a floor price commitment for all NdPr products sold or stockpiled, as well as other commitments and features as further described in <u>[Note](#i36e728074715429b91883a0ff85e6f7d_103)</u><u>22[, "Subsequent Events."](#i36e728074715429b91883a0ff85e6f7d_103)</u> As part of the agreements with the DoD and as noted above, the Company will cease sales of all products to China and prioritize a vibrant domestic and ex-China supply chain for rare earth products.

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 floor price commitment under the agreements with the DoD, 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 primary focus in the Asian market due to the refining, metallization, and magnet manufacturing capabilities of the region. See the <u>["Concentration of Risk"](#i3866851d6dde4bd2895cc20661b408b0_8608)</u> section in <u>[Note](#i36e728074715429b91883a0ff85e6f7d_40)</u><u>2</u><u>[, "Significant Accounting Policies,"](#i36e728074715429b91883a0ff85e6f7d_40)</u> for additional information. Rare earth products are critical inputs in hundreds of existing and emerging clean-tech applications including electric vehicles and wind turbines as well as robotics, drones, and defense applications.

***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.

As of June 30, 2025, Shenghe was the principal customer of the Materials segment and accounted for approximately 40% of the Company's consolidated revenue for the six months ended June 30, 2025, the vast majority of which related to sales of concentrate, versus approximately 80% of the Company's consolidated revenue for the six months ended June 30, 2024 (see <u>[Note](#i36e728074715429b91883a0ff85e6f7d_94)</u><u>19</u><u>[, "Related-Party Transactions"](#i36e728074715429b91883a0ff85e6f7d_94)</u> for additional information). In July 2025, to align with the terms of the DoD Transaction Agreements and in further support of its domestic supply chain objectives, the Company ceased all further sales of its products to China and determined it would not exercise its right to extend the term of the Shenghe Offtake Agreement when it expires in January 2026.

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. Following the Company's announcement of ceasing shipments of rare earth concentrate to China, rare earth concentrate revenues declined for the three months ended June 30, 2025, and with the cessation of all further sales to China starting in July 2025, the Company continues to focus on further processing the concentrate into separated rare earth products or stockpiling it for future use. However, the price protection commitment provided by the DoD under the DoD Transaction Agreements is designed to dampen the negative effects of these other market factors on the Materials segment, as are the demand-side commitments under the supply agreements with GM, the DoD and Apple with respect to the Magnetics segment.

***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](#i36e728074715429b91883a0ff85e6f7d_79)</u><u>14</u><u>[, "Revenue Recognition,"](#i36e728074715429b91883a0ff85e6f7d_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](#i36e728074715429b91883a0ff85e6f7d_85)16[, "Stockholders' Equity and Stock-Based Compensation,"](#i36e728074715429b91883a0ff85e6f7d_85)</u> for additional information.

***Convertible Debt and Embedded Derivatives:*** The Company accounts for its convertible debt in accordance with Accounting Standards Codification ("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 accordance with ASC Topic 815, "Derivatives and Hedging," 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. As of June 30, 2025, the fair value of the redemption feature included in the portion of the 2030 Notes (as defined in <u>[Note](#i36e728074715429b91883a0ff85e6f7d_64)</u><u>10</u><u>[, "Debt Obligations"](#i36e728074715429b91883a0ff85e6f7d_64)</u>) that were issued in December 2024 was $4.5 million and is included in "Other non-current assets" within the Company's unaudited Condensed Consolidated Balance Sheets. The fair value of the same feature as of December 31, 2024, was not material. Changes in the fair value each reporting period are included in "Other income, net" within the Company's unaudited Condensed Consolidated Statements of Operations. See <u>[Note](#i36e728074715429b91883a0ff85e6f7d_88)</u><u>17[, "Fair Value Measurements,"](#i36e728074715429b91883a0ff85e6f7d_88)</u> for additional information.

***Recently Adopted Accounting Pronouncements:*** During the three and six months ended June 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](#i36e728074715429b91883a0ff85e6f7d_97)20[, "Segment Reporting,"](#i36e728074715429b91883a0ff85e6f7d_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 disclosures.

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 six months ended June 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 June 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 six months ended June 30, 2025 and 2024.

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

**NOTE 4—INVENTORIES**

The Company's inventories consisted of the following:

---

&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 $22.5 million and $10.2 million as of June 30, 2025, respectively, and $12.3 million and zero as of December 31, 2024, respectively.

As of June 30, 2025, and 2024, the Company recorded lower of cost or net realizable value reserves of $6.7 million and $17.8 million, respectively, on certain work in process and finished goods inventories. These amounts represent increases of $3.5 million and $11.8 million from the reserves recorded as of March 31, 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 $66.2 million and $96.1 million for the six months ended June 30, 2025, and 2024, respectively, including amounts not yet paid (see <u>[Note](#i36e728074715429b91883a0ff85e6f7d_100)</u><u>21</u><u>[, "Supplemental Cash Flow Information"](#i36e728074715429b91883a0ff85e6f7d_100)</u>) and excluding equipment purchased with promissory notes (see <u>[Note](#i36e728074715429b91883a0ff85e6f7d_64)</u><u>10</u><u>[, "Debt Obligations"](#i36e728074715429b91883a0ff85e6f7d_64)</u>). The capitalized expenditures for the six months ended June 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 separations facility for heavy rare earth elements.

There were no property, plant and equipment impairments recognized for the three and six months ended June 30, 2025 and 2024.

**NOTE 6—EQUITY METHOD INVESTMENT**

The Company's equity method investment balance, which is included in "Other non-current assets" within the Company's unaudited Condensed Consolidated Balance Sheets, was zero and $9.1 million, as of June 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.

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 three and six months ended June 30, 2025 and 2024.

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. No impairment charges were recorded during the three and six months ended June 30, 2025 and 2024.

**NOTE 7—INTANGIBLE ASSETS**

The Company's intangible assets were as follows:

---

| **Intangible assets, net** | $6772 | $7370 |

---

Amortization expense related to amortizing intangible assets was $0.3 million and $0.6 million, respectively, for both the three and six months ended June 30, 2025 and 2024. No impairment charges were recorded during the three and six months ended June 30, 2025 and 2024.

**NOTE 8—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 June 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 June 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 six months ended June 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 $7.5 million and $7.2 million as of June 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 $51.5 million and $51.6 million as of June 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 June 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 six months ended June 30, 2025 and 2024.

The total estimated aggregate undiscounted cost of $39.0 million and $39.5 million as of June 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 June 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 June 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.

***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 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 six months ended June 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 June 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 becoming convertible 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.

***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.

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 expected generally 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, 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 will 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** | $7554 | $6715 | $15100 | $9542 |

---

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 0.8 year and 4.7 years, respectively, as of June 30, 2025.

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

***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 six months ended June 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 June 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](#i36e728074715429b91883a0ff85e6f7d_100)</u><u>21</u><u>[, "Supplemental Cash Flow Information."](#i36e728074715429b91883a0ff85e6f7d_100)</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:

**NOTE 11—LEASES**

The Company has operating and finance leases for corporate office space, warehouses, vehicles and equipment used in its operations. The Company's lease agreements do not contain material residual value guarantees or restrictive covenants. As of June 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 six months ended June 30, 2025 and 2024.

**NOTE 12—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 27.7% and 23.4% for the three and six months ended June 30, 2025, respectively, as compared to 29.3% and 28.4% for the three and six months ended June 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 June 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 48C Credit is not eligible for direct pay (i.e., it is nonrefundable); however, it is transferable to an unrelated taxpayer at a negotiated rate. 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.

**NOTE 13—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 scheduled to go to binding arbitration. The Company disputes that it owes any monies (and believes it has a valid claim against the contractor) in connection with this construction project. The Company is unable to estimate a range of loss, if any, at this time. 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 any such outcome becomes probable and reasonably estimable.

**NOTE 14—REVENUE RECOGNITION**

The following table disaggregates the Company's revenue from contracts with customers by segment and by type of good sold, which are transferred to customers at a point in time:

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 six months ended June 30, 2025, the Company recognized $19.9 million and $25.1 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 six months ended June 30, 2024.

***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 June 30, 2025, the Company classified $79.9 million of the $124.9 million total remaining prepayment as current deferred revenue and $45.1 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 will be satisfied within one year after June 30, 2025, and between approximately one and two years after the same date for the non-current deferred revenue. The Company's estimate of when the performance obligations will be satisfied and revenue will be recognized is dependent upon the timing of the production ramp of NdPr metal at the Independence Facility. There were no other deferred revenue balances as of both June 30, 2025 and December 31, 2024.

**NOTE 15—GOVERNMENT GRANTS**

***Asset-Based Grants:*** In February 2022, the Company was awarded a $35.0 million contract by the Department of Defense Office of Industrial Base Analysis and Sustainment program to design and build a facility to process heavy rare earth elements ("HREE") at Mountain Pass (the "HREE Facility") (the "HREE Production Project Agreement"). The funds received pursuant to the HREE Production Project Agreement reduce the carrying amount of the fixed assets associated with the HREE Facility. During the six months ended June 30, 2025, the Company received $12.2 million from the DoD under the HREE Production Project Agreement. No such funds were received from the DoD during the six months ended June 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 June 30, 2025, and December 31, 2024, the government grant receivable balance and deferred government grant within the Company's unaudited Condensed Consolidated Balance Sheets pertained to the 45X Credit. The non-current portion of government grant receivable, which is included in "Other non-current assets," was $11.4 million and zero as of June 30, 2025 and December 31, 2024, respectively. The current portion of deferred government grant, which is included in "Other current liabilities," was $2.3 million and $2.0 million as of June 30, 2025 and December 31, 2024, respectively.

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

**NOTE 16—STOCKHOLDERS' EQUITY AND STOCK-BASED COMPENSATION**

***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 Program was also extended and was effective until August 30, 2026. The authorization did not require the purchase of any minimum number of shares.

As of June 30, 2025, $375.0 million was available for additional share repurchases under the Program. On July 11, 2025, pursuant to the terms of the DoD Transaction Agreements, the Company terminated the Program. See <u>[Note](#i36e728074715429b91883a0ff85e6f7d_103)</u><u>22[, "Subsequent Events"](#i36e728074715429b91883a0ff85e6f7d_103)</u> for additional information regarding the DoD Transaction Agreements.

During the six months ended June 30, 2024, the Company repurchased 13.0 million shares of its common stock at an aggregate cost of $200.8 million. Of the number of shares repurchased during the six months ended June 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 six months ended June 30, 2025 and the three months ended June 30, 2024.

***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 June 30, 2025, the Company has not issued any stock options or SARs and there were 4,688,821 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 six months ended June 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 17—FAIR VALUE MEASUREMENTS**

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

---

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

---

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

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

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.

***Derivative Instrument***

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

---

| | |
|:---|:---|
| **Valuation Assumptions:** | **June 30, 2025** |
| &nbsp;&nbsp;&nbsp;&nbsp;Expected volatility | 60.9% |
| &nbsp;&nbsp;&nbsp;&nbsp;Risk-free interest rate | 3.8% |
| &nbsp;&nbsp;&nbsp;&nbsp;Discount rate | 8.8% |
| &nbsp;&nbsp;&nbsp;&nbsp;Dividend yield | —% |
| &nbsp;&nbsp;&nbsp;&nbsp;Term to maturity | 4.7 years |
| &nbsp;&nbsp;&nbsp;&nbsp;Stock price | $33.27 |

---

***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.

***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 of liabilities classified within Level 2 of the fair value hierarchy.

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 18—EARNINGS (LOSS) PER SHARE**

Basic earnings or loss per share is computed by dividing net income or loss by the weighted-average number of common shares outstanding during the period. Diluted earnings or loss per share is computed by dividing net income or loss by the weighted-average number of common shares outstanding plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method or the if-converted method, as applicable. During the periods when there is a net loss, potentially dilutive common stock equivalents have been excluded from the calculation of diluted loss per share as their effect is anti-dilutive.

&nbsp;&nbsp;&nbsp;&nbsp;(1)The six months ended June 30, 2024, were tax-effected at a rate of 28.4%.

&nbsp;&nbsp;&nbsp;&nbsp;(2)The 2026 Notes were antidilutive for the three and six months ended June 30, 2025 and for the three months ended June 30, 2024. Convertible debt becomes antidilutive whenever the combined impact of interest expense and any gains or losses recognized on actual settlements of convertible debt (net of tax) per common share obtainable upon conversion exceeds basic earnings or loss per share.

&nbsp;&nbsp;&nbsp;&nbsp;(3)Pertains to the 2026 Notes, a portion of which were repurchased during the six months ended June 30, 2024.

In connection with the issuance of the 2030 Notes in March 2024, the Company entered into 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 Capped Call Options are expected to partially offset the potential dilution to the Company's common stock upon any conversion of the 2030 Notes. The Company has not exercised any of the Capped Call Options as of June 30, 2025.

As discussed in <u>[Note](#i36e728074715429b91883a0ff85e6f7d_64)</u><u>10</u><u>[, "Debt Obligations,"](#i36e728074715429b91883a0ff85e6f7d_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 19—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 April 2025, in response to China's retaliatory tariffs and export controls, the Company announced the strategic decision to cease shipments of rare earth concentrate to China, which significantly reduced the sales made to Shenghe under the terms of the Shenghe Offtake Agreement for the three months ended June 30, 2025. Furthermore, in July 2025, to align with the terms of the DoD Transaction Agreements, the Company ceased making any additional sales under the Shenghe Offtake Agreement and determined that it would not exercise its right to extend the term of the Shenghe Offtake Agreement when it expires in January 2026. See <u>[Note](#i36e728074715429b91883a0ff85e6f7d_103)</u><u>22[, "Subsequent Events"](#i36e728074715429b91883a0ff85e6f7d_103)</u> for additional information regarding the DoD Transaction Agreements.

***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 caused VREX to process into NdPr metal for delivery to the Company's customers globally in exchange for a processing fee per unit of rare earth metal produced paid to VREX Holdco. The Company maintained title to the products and directly entered into sales agreements for the produced NdPr metal.

During the second quarter of 2025, after all required regulatory approvals were received, the Company sold its 49% interest in VREX Holdco in exchange for a cash payment of $9.7 million. See <u>[Note](#i36e728074715429b91883a0ff85e6f7d_52)</u><u>6</u><u>[, "Equity Method Investment,"](#i36e728074715429b91883a0ff85e6f7d_52)</u> for additional information.

***Purchases of Materials and Supplies:*** The Company purchases certain reagent products (generally produced by an unrelated third-party manufacturer) used in the flotation process, as well as other materials from Shenghe in the ordinary course of business. Total purchases were zero and $16.1 million for the three and six months ended June 30, 2025, respectively, as compared to $1.2 million and $2.3 million for the three and six months ended June 30, 2024, respectively.

***Accounts Receivable:*** As of June 30, 2025, and December 31, 2024, $8.1 million and $14.9 million, respectively, of the accounts receivable as stated within the Company's unaudited Condensed Consolidated Balance Sheets, were receivable from and pertained to sales made to Shenghe in the ordinary course of business.

***Aircraft Lease and Time Sharing Agreement:*** On November 13, 2024, the Company entered into an aircraft operating lease agreement effective as of January 1, 2025, with an entity affiliated with James H. Litinsky, the Company's Chairman and Chief Executive Officer, providing for the lease of an aircraft (the "Aircraft Lease"). The rent payable by the Company under the Aircraft Lease is $0.5 million per year.

In addition, on November 13, 2024, the Company entered into a time sharing agreement effective as of January 1, 2025, with Mr. Litinsky, pursuant to which he may lease the aircraft from the Company for limited personal use ("Time Sharing Agreement"). For flights taken under the Time Sharing Agreement, Mr. Litinsky will pay for the actual expenses of such flights as listed in the Time Sharing Agreement, but not to exceed the maximum amount permitted under the Federal Aviation Administration rules.

In connection with the Company's use of the aircraft, the Company contracted with a third party and will pay for certain fixed and variable expenses associated with the Company's use of the aircraft.

**NOTE 20—SEGMENT REPORTING**

The Company's reportable segments, which are primarily based on the Company's internal organizational structure and types of products, are 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 (i) sales of rare earth concentrate, which was historically primarily sold for further distribution to a single customer in China, and (ii) sales of NdPr oxide and metal, primarily sold to customers in Japan, South Korea, and broader Asia. Refer to the <u>["Concentration of Risk"](#i3866851d6dde4bd2895cc20661b408b0_8608)</u> section in <u>[Note](#i36e728074715429b91883a0ff85e6f7d_40)</u><u>2</u><u>[, "Significant Accounting Policies,"](#i36e728074715429b91883a0ff85e6f7d_40)</u> and <u>[Note](#i36e728074715429b91883a0ff85e6f7d_94)</u><u>19</u><u>[, "Related-Party Transactions,"](#i36e728074715429b91883a0ff85e6f7d_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 income or loss before income taxes for the three and six months ended June 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.

On July 9, 2025, the Company entered into definitive agreements (collectively, the "DoD Transaction Agreements") establishing a transformational public-private partnership with the DoD to accelerate the development of a fully integrated domestic rare earth magnet supply chain and to reduce reliance on foreign imports (the "DoD Transactions"). The DoD Transactions consist of a comprehensive, long-term package of commitments from the DoD, including equity investments, loan financing, purchase commitments, and pricing support. The key terms of the DoD Transactions are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Convertible Preferred Equity and Warrant:*** The DoD purchased $400 million of a newly-created series of the Company's convertible preferred stock and received a warrant to purchase up to approximately 11.2 million additional shares of the Company's common stock. The initial conversion and exercise price for the preferred shares and warrant is $30.03 per share. The warrant is exercisable for a period of 10 years. Upon full conversion and exercise, the DoD would hold approximately 15% of the Company's outstanding common stock (on an as-converted and as-exercised basis as of July 9, 2025).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***10-Year NdPr Price Floor Commitment:*** The DoD committed to a 10-year price floor of $110 per kilogram for the Company's NdPr products beginning in the fourth quarter of 2025, providing earnings stability and mitigating market price volatility.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***10-Year Magnet Offtake Agreement:*** The DoD agreed to ensure (i) that 100% of the magnets produced at the Company's planned 10X Magnet Manufacturing Facility ("10X Facility") will be purchased by the DoD, or another third party with the DoD's consent, for a period of 10 years following the facility's commissioning and (ii) that the 10X Facility will generate at least $140 million of EBITDA (as defined in the offtake agreement with the DoD) on an annual basis, adjusted 2% annually beginning 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Loan Financing:*** The Company received $150 million in loan proceeds from the DoD, which will support the expansion of heavy rare earth separation capabilities at Mountain Pass.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Debt Commitment for Facility Construction:*** JPMorgan Chase Funding Inc. and Goldman Sachs Bank USA have issued a commitment letter to provide up to $1.0 billion in financing for the construction of the 10X Facility. The commitment was subsequently reduced by the amount of the net proceeds from the Offering.

***One Big Beautiful Bill Act***

On July 4, 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 Company is currently evaluating the impact of the OBBBA on its unaudited Condensed Consolidated Financial Statements, and the results of such evaluations will be reflected in the Company's Form 10-Q for the three and nine months ended September 30, 2025, the periods in which the OBBBA was enacted.

This discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. The actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, including, but not limited to, those set forth under <u>["Part II. Item 1A. Risk Factors"](#i36e728074715429b91883a0ff85e6f7d_169)</u> and elsewhere in this Form 10-Q and "Part I. Item 1A. Risk Factors" and elsewhere in our Form 10-K.

**Business Overview**

MP Materials Corp., including its subsidiaries ("we," "our," and "us"), 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. 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. In April 2025, in response to China's retaliatory tariffs and export controls, we made the strategic decision to cease shipments of rare earth concentrate to China. In July 2025, to align with the terms of the DoD Transaction Agreements (as defined below) and in further support of our domestic supply chain objectives, we agreed to cease all future sales of products to China. See the <u>["Recent Developments"](#i36e728074715429b91883a0ff85e6f7d_112)</u> and <u>["Liquidity and Capital Resources"](#i36e728074715429b91883a0ff85e6f7d_136)</u> sections for further details.

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, where we produce and sell magnetic precursor products and anticipate manufacturing neodymium-iron-boron ("NdFeB") permanent magnets by the end of 2025. 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.

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.

The Underwriters purchased the shares of our common stock at a price of $53.35 per share. We also granted the underwriters a 30-day option, which was exercised in full, to purchase up to an additional 1,772,727 shares of our common stock, solely to cover over-allotments, at the public offering price less the underwriting discount. Our net proceeds from the Offering are expected to be approximately $724 million, after deducting our underwriting discounts and commissions and other estimated offering expenses. We currently intend to use the net proceeds from the Offering to fund the acceleration and expansion of our

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

*Development, Supply and Pricing Commitments*

As part of the DoD Transactions, we agreed to use reasonable best efforts to build our planned 10X Magnet Manufacturing Facility (the "10X Facility") to produce sintered NdFeB permanent magnet blocks and/or other finished magnets. Additionally, we agreed to use reasonable best efforts to (i) expand heavy rare earth elements ("HREE") refining capacity at Mountain Pass, which, after the DoD extends the Samarium Project Loan (as defined below) to us in accordance with the DoD Transaction Agreements, will include separation of samarium oxide, (ii) recommission the chlor-alkali facilities at Mountain Pass and (iii) 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.

Under the NdPr price floor protection agreement (the "PPA"), the DoD will pay us a quarterly payment per kilogram ("KG") of NdPr produced by us equal to the shortfall between $110 per KG and the Benchmark Quarterly Average Volume Weighted Price (as defined in the PPA). If, after the 10X Facility reaches full production capacity, the Benchmark Quarterly Average Volume Weighted Price for the prior quarter exceeds $110 per KG, the DoD will be entitled to receive 30% of the NdPr sales price which exceeds $110 per KG. The term of the PPA will commence on the first day of the fourth quarter of 2025 and will continue for ten years and will apply to all of our products that contain NdPr (i.e., concentrate, oxide and metal).

The PPA provides that we will prioritize the supply of NdPr first to magnet manufacturing, with excess volumes remaining available for sale to commercial customers, subject to a prohibition on sales to certain Restricted Buyers (as defined in the PPA) and certain other obligations.

Pursuant to the terms of the offtake agreement (the "DoD Offtake Agreement"), the DoD agreed to purchase the entire quantity of magnets produced at the 10X Facility; provided however, that up to 100% of magnet production may be syndicated to commercial and other customers under certain conditions. The DoD Offtake Agreement has a term of ten years following the Commercial Operation Date (as defined in the DoD Offtake Agreement) of the 10X Facility. In accordance with the DoD Offtake Agreement, the 10X Facility will generate at least $140 million of EBITDA (as defined in the DoD Offtake Agreement) on an annual basis after reaching full production capacity, adjusted annually in each calendar year following 2025 for inflation at a rate equal to 2% (the "Threshold EBITDA Amount"). The DoD will also acquire magnets from us at a price equal to the production costs incurred in connection with the production of magnets at the 10X Facility.

The DoD will make quarterly payments to us in an amount equal to 25% of the applicable Threshold EBITDA Amount. Once the 10X Facility begins producing magnets at target levels, in the event that any portion of the magnet production from the 10X Facility in an applicable year is syndicated to third-party purchasers, the DoD will be entitled to receive (i) the first $30 million of EBITDA attributed to the 10X Facility magnet production that exceeds the Threshold EBITDA Amount (the "Initial Excess Amount") and (ii) 50% of the EBITDA attributable to the 10X Facility magnet production that exceeds the Initial Excess Amount on an annual basis in that year. Before the Commercial Operation Date, the DoD will also make payments in respect of certain incremental costs incurred by us including in connection with the engineering, development and start up of the 10X Facility and for designing magnets to the DoD's specifications, with such payments being capped at $30 million in any calendar year. The DoD Offtake Agreement also prohibits magnet sales to certain Restricted Buyers and imposes certain other obligations.

We also agreed to terminate our existing share repurchase program and to cease making sales under the Shenghe Offtake Agreement (as defined in <u>[Note](#i36e728074715429b91883a0ff85e6f7d_94)</u><u>19</u><u>[, "Related-Party Transactions,"](#i36e728074715429b91883a0ff85e6f7d_94)</u> in the notes to the unaudited Condensed Consolidated Financial Statements), which expires in January 2026, and will not be renewed.

*Financings*

As part of the financing for the projects described above, we sold to the DoD $400 million of newly created Series A Cumulative Perpetual Convertible Preferred Stock, par value $0.0001 per share (the "Series A Preferred Stock"). The Series A Preferred Stock is convertible by the initial holder thereof at any time and from time to time after 45 days of issuance into approximately 13.3 million shares of our common stock, subject to customary adjustments for stock splits, combinations, non-cash dividends and certain corporate transactions.

Shares of the Series A Preferred Stock accrue cumulative dividends at a rate of 7.0% per year (the "Dividend Rate"), 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"). While the terms of the Series A Preferred Stock do not restrict the payment of cash dividends by the Company, within the first 15 business days of each new fiscal year, we will pay to the holder of each share of Series A Preferred Stock, on an as-converted basis, cash per share of common stock representing the amount, if any, by which the annual yield of the aggregate cash dividends paid by us on each share of common stock in the prior fiscal year exceeded the Dividend Rate.

At any time after the five year anniversary of issuance, if the closing price per share of common stock exceeds 150% of the then-current conversion price for at least 20 trading days in any period of 30 consecutive trading days, we will have the option to require all or any portion of the then-outstanding shares of Series A Preferred Stock be converted into common stock at the then-current conversion price, subject to certain liquidity and other conditions.

We also issued a warrant (the "Warrant") to the DoD, exercisable at any time and from time to time after 45 days of issuance for a period of 10 years for up to 11,201,659 shares of our common stock, at an initial exercise price of $30.03 per share, such price subject to certain 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 represent 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, JPMorgan Chase Funding Inc. and Goldman Sachs Bank USA agreed to provide committed secured financing, subject to customary terms and conditions, in an amount equal to, in the aggregate, at least $1 billion, $650 million of which will, pursuant to the terms of the committed secured financing, be specifically allocated to the construction of the 10X Facility; provided, that such $1 billion may be reduced on a dollar-for-dollar basis for certain equity and/or debt raises (including the proceeds from the Offering discussed above) and certain unrestricted cash that is not segregated or otherwise earmarked for use as contemplated by the DoD Transaction Agreements.

We also received a loan from the DoD in the aggregate principal amount of $150 million (the "Samarium Project Loan"), pursuant to an unsecured promissory note (the "Promissory Note") maturing 12 years after issuance. Interest will accrue on the Samarium Project Loan at a rate equal to the 10-year U.S. Treasury constant maturity rate plus 1.00% and will be payable in cash quarterly in arrears.

***One Big Beautiful Bill Act***

On July 4, 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 Section 45X Advanced Manufacturing Production Credit (the "45X Credit") by 2034. We are currently evaluating the impact of the OBBBA on our business, results of operations and financial position, and the results of such evaluations will be reflected in our unaudited Condensed Consolidated Financial Statements in the third quarter of 2025, the period in which the OBBBA was enacted.

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

During the second quarter 2025, after all required regulatory approvals were received, 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](#i36e728074715429b91883a0ff85e6f7d_52)</u><u>6</u><u>[, "Equity Method Investment,"](#i36e728074715429b91883a0ff85e6f7d_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***

In response to China's retaliatory tariffs and export controls introduced in April 2025, we announced the strategic decision to cease shipments of rare earth concentrate to China. 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. In July 2025, to align with the terms of the DoD Transaction Agreements and in further support of our domestic supply chain objectives, we ceased all further sales of our products to China and determined we would not exercise our right to extend the term of the Shenghe Offtake Agreement when it expires in January 2026.

We continue to produce concentrate, and to the extent not sold or further processed and sold as separated product, we will 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.

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.

Furthermore, as mentioned in the <u>["Recent Developments"](#i36e728074715429b91883a0ff85e6f7d_112)</u> section above, in April 2025, China imposed export controls, which included export restrictions on seven heavy REE and certain magnet materials containing heavy REE. The new restrictions require companies to secure special export licenses to export the specified REE and magnet materials containing heavy REE. This development has led 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 achieved 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 the first half of 2025. Our Stage I optimization plan has enabled us to achieve 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 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 DoD, we have committed to further expand our refining capacity to include the separation of samarium oxide and to expand and recommission the chlor-alkali facilities at Mountain Pass. Additionally, as part of our agreement with Apple, we will continue to develop and install scaled 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 metal into 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 DoD and Apple described in the <u>["Recent Developments"](#i36e728074715429b91883a0ff85e6f7d_112)</u> section above.

In December 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 DoD, we committed to continue the expansion in capacity of the Independence Facility to a projected 3,000 MTs of magnets annually

<u>[T](#i36e728074715429b91883a0ff85e6f7d_7)[able of Contents](#i36e728074715429b91883a0ff85e6f7d_7)</u>

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 finished 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. 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"](#i36e728074715429b91883a0ff85e6f7d_124)</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 is 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 our cessation of shipments of concentrate as discussed in the <u>["Recent Developments"](#i36e728074715429b91883a0ff85e6f7d_112)</u> section above, we do not expect historical REO Sales Volume to be representative of future volumes.

***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 is an important measure of the market price of our concentrate product.

***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 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 the exchange rate between the Chinese Yuan and the U.S. dollar.

***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. As we ramp up production of separated rare earth products, we expect our NdPr oxide and metal revenue to become a larger portion of our total revenue. Accordingly, to the extent we sell a greater volume of NdPr oxide and NdPr metal, rare earth concentrate revenue will decline in future periods.

***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 three and six months ended June 30, 2025, as compared to the respective prior year periods, as a result of ramping production of separated products throughout 2024, resulting in higher NdPr oxide and metal revenue in the current year. Additionally, during the three and six months ended June 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 the decreases in rare earth concentrate revenues, impacted by the strategic decision to cease shipments of rare earth concentrate 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"](#i36e728074715429b91883a0ff85e6f7d_112)</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. See the <u>["Segment Results"](#i187c7e820a5c4fb1a669318a01ce28aa_3310)</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) | $50431 | $41463 | 22% | $99262 | $77057 | 29% |

---

The increases in COS for the three and six months ended June 30, 2025, were driven by higher sales of NdPr oxide and metal in the current year periods, as discussed above, offset partially by a decline in per-unit production costs associated with separated rare earth products as we continue to optimize production. 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.

The year-over-year increases are further impacted by the production costs associated with the magnetic precursor products sold in the current year, specifically NdPr metal at the Independence Facility, with no comparable costs in the prior year. Lastly, COS for the three and six months ended June 30, 2025, benefited from (i) a lower reserve on certain of our work in process and finished goods inventories, which decreased by $8.3 million and $11.1 million, respectively, when compared to the respective prior year periods; (ii) $1.9 million and $4.7 million, respectively, of higher 45X Credit impacts in the respective current year periods; and (iii) $1.9 million in lower repairs and maintenance expenses, attributable to thickener equipment damage costs incurred in the second quarter of 2024.

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 would 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 | $27429 | $21434 | 28% | $51595 | $42701 | 21% |

---

The increases in SG&A expenses for the three and six months ended June 30, 2025, as compared to the respective prior year periods, were driven primarily by higher legal costs. Additionally, higher personnel costs (excluding stock-based compensation expense, which decreased modestly) contributed $2.4 million and $3.4 million, respectively, of the increase in the current respective year periods, due to higher executive and administrative personnel costs, as well as 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.

| Depreciation, depletion and amortization | $20777 | $18210 | 14% | $42161 | $36595 | 15% |

---

The year-over-year increases in DD&A for the three and six months ended June 30, 2025, primarily reflect increases in depreciation of $4.0 million and $7.3 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.

***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 | $761 | $1373 | (45)% | $1737 | $2660 | (35)% |

---

The year-over-year decreases in start-up costs for three and six months ended June 30, 2025, were attributable primarily to our midstream operations, where start-up activities have been completed as production of separated products commenced in late 2023. Start-up costs attributable to our downstream initiatives decreased year over year, in line with the commencement of our production of magnetic precursor products at Independence in late 2024.

***Advanced projects and development***

Advanced projects and development consists principally of costs incurred in connection with research and development of new processes or to significantly enhance our existing processes; and certain government contracts, as well as costs incurred to support growth initiatives or pursue other opportunities.

| Advanced projects and development | $2496 | $1886 | 32% | $2970 | $6092 | (51)% |

---

The year-over-year increase in advanced projects and development for the three months ended June 30, 2025, was primarily due to higher transaction costs, largely associated with the transactions described in the <u>["Recent Developments"](#i36e728074715429b91883a0ff85e6f7d_112)</u> section above. The year-over-year decrease for the six months ended June 30, 2025, was driven by (i) lower research and development costs, attributable to the start of production of magnetic precursor products at the Independence Facility during the first quarter of 2025, and (ii) $1.4 million in lower costs incurred for legal, consulting, and advisory services to support growth initiatives, such as potential acquisitions, mergers, or other investments.

***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 six months ended June 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, offset by capitalized interest.

| Interest expense, net | $5414 | $6745 | (20)% | $13029 | $9602 | 36% |

---

Interest expense, net for the three months ended June 30, 2025, decreased year over year primarily due to higher capitalized interest in the current year period. Interest expense, net for the six months ended June 30, 2025, increased year over year due to the issuance of the 2030 Notes, 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 six months ended June 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"](#i36e728074715429b91883a0ff85e6f7d_136)</u> section below for additional information.

***Other income, net*** 

Other income, net consists of interest and investment income, changes in fair value of derivative instruments, and non-operating gains or losses.

| Other income, net | $6572 | $12084 | (46)% | $21790 | $24741 | (12)% |

---

Other income, net for the three and six months ended June 30, 2025, decreased year over year primarily as a result of lower interest and investment income earned on our short-term investments, whose balance decreased over the applicable periods. 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 $2.5 million loss and a $4.5 million gain for the three and six months ended June 30, 2025, respectively. Finally, both the three and six months ended June 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 six months ended June 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 six months ended June 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 six months ended June 30, 2025, were primarily driven by the decreases in REO Sales Volume impacted by the strategic decision to cease shipments of rare earth concentrate 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. This was partially offset by a higher Realized Price per REO MT. As noted above in the <u>["Factors Affecting our Performance"](#i36e728074715429b91883a0ff85e6f7d_115)</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 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 and not sold as concentrate. 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 continue to expect that REO Sales Volume will be significantly lower than REO Production Volume and 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.

The increases in NdPr oxide and metal revenue for the three and six months ended June 30, 2025, as compared to the respective prior year periods, was primarily driven by higher NdPr Production Volume as a result of ramping production of separated products throughout 2024. NdPr oxide and metal revenue for the three months ended June 30, 2025, also benefited from higher NdPr Realized Price per KG as compared to the prior year period. We currently expect to begin intersegment sales of NdPr oxide to the Magnetics segment starting in the second half of 2025.

The improvement in Materials Segment Adjusted EBITDA for the three and six months ended June 30, 2025, when compared to the respective prior year periods, were primarily due to the net increases in revenue, as discussed above, with the six months ended June 30, 2025, comparable period being partially offset by higher cost of sales (excluding depreciation, depletion and amortization and stock-based compensation expense) ("Segment COS").

While the year-over-year Segment COS remained relatively flat for the comparable three months ended June 30, 2025, the increase in Segment COS for the six months ended June 30, 2025, was driven primarily by higher production costs associated with separated rare earth products sold in the current year period, which are currently elevated as we continue to ramp and optimize production of separated products toward normalized capacity. Segment COS for the three and six months ended June 30, 2025, benefited from (i) lower reserves on certain of our work in process and finished goods inventories, which decreased by $8.3 million and $11.1 million, respectively, when compared to the respective prior year periods; (ii) $1.9 million and $4.7 million, respectively, of higher 45X Credit impacts in the respective current year periods; and (iii) $1.9 million in lower repairs and maintenance expenses, attributable to thickener equipment damage in the second quarter of 2024.

***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. Pursuant to the long-term supply agreement with GM, we received prepayments of $50.0 million in April 2025 and $100.0 million during the year ended December 31, 2024, for magnetic precursor products.

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](#i36e728074715429b91883a0ff85e6f7d_79)</u><u>14</u><u>[, "Revenue Recognition,"](#i36e728074715429b91883a0ff85e6f7d_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 significantly impacted by the production ramp 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 six months ended June 30, 2025, as compared to the respective prior year periods, was primarily due to higher personnel costs (other than stock-based compensation expense) related to executives and administrative personnel.

**Quarterly Performance Trend**

While our business is not highly seasonal in nature, we sometimes experience a timing lag between production and sales, which may result in volatility in our results of operations between periods. The timing lag may be the result of, or influenced by, factors such as the timing and duration of shipments or the time required to convert materials. In addition, quarterly production of concentrate and separated products is impacted by the timing of scheduled outages of our production facilities for maintenance, which typically occur in the second and fourth quarters. Finally, since we began production of separated rare earth materials in the second half of 2023, certain volumes of REO produced are further processed or rejected rather than sold as concentrate.

The following table presents our KPIs, which pertain to the Materials segment, for the quarterly periods indicated:

**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. Since becoming a public company, our principal sources of liquidity have been the issuance of the 2026 Notes in March 2021, and net cash from operating activities. In addition, we issued the 2030 Notes in March 2024, resulting in net proceeds of $731.4 million prior to the use of a portion of these funds to repurchase the 2026 Notes, repurchase shares of our common stock, and purchase Capped Call Options, as discussed below. As of June 30, 2025, we had $753.7 million of cash, cash equivalents and short-term investments and $930.5 million of principal amount of long-term debt, including $67.7 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 concerns over the global economic conditions and actual or perceived concerns over increases in the supply of and/or decreases in demand for rare earth products. For example, the significant decrease in the market price of rare earth products in 2024 negatively impacted our cash flows from operations and liquidity.

In response to China's retaliatory tariffs and export controls introduced in April 2025, we announced the decision to cease shipments of rare earth concentrate to China and in July 2025, to align with the terms of the DoD Transaction Agreements and in further support of our domestic supply chain objectives, we ceased all further sales of our products to China and determined

<u>[T](#i36e728074715429b91883a0ff85e6f7d_7)[able of Contents](#i36e728074715429b91883a0ff85e6f7d_7)</u>

we would not exercise our right to extend the term of the Shenghe Offtake Agreement when it expires in January 2026. We continue to prioritize further processing concentrate into separated rare earth products or stockpiling for future use.

Accordingly, 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 once the NdPr price protection component of the DoD Transactions begins in the fourth quarter of 2025 and provides us with pricing stability. We continue to 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 DoD Transactions, we received significant cash investments and future commitments from the DoD, and in July 2025, we also received a prepayment commitment from Apple, while raising approximately $724 million in net proceeds in the Offering. See the <u>["Recent Developments"](#i36e728074715429b91883a0ff85e6f7d_112)</u> section for additional information.

While the DoD 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; further actions that the U.S. government may take in encouraging domestic production of critical minerals and reducing reliance on foreign imports; and 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; our working capital needs have also increased as a result of the DoD Transactions and our agreement with Apple, and we expect those needs may continue to see further increases in 2025 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, as well as commissioning of our magnet manufacturing capabilities.

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***

***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.

Contemporaneous with the pricing of the 2030 Notes, 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.

***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 of cash and shares of our common stock, 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.

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, 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 expected generally 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, 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 will not have any rights with respect to the Capped Call Options. We paid $65.3 million for the Capped Call Options in March 2024.

***Equipment Notes:*** We have financing agreements for the purchase of certain equipment, including trucks and loaders. As of June 30, 2025, we had $26.2 million in principal (and accrued interest) outstanding under the 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 six months ended June 30, 2025, we executed promissory notes under the Uncommitted Credit Facility to finance new equipment for use at Mountain Pass. As of June 30, 2025, we had no available borrowing capacity under the Uncommitted Credit Facility. The interest rates for the various borrowings approximated market rates at the time of borrowing and are fixed for the duration of the respective advances.

***Leases:*** We have lease arrangements for certain equipment and facilities, including office space, vehicles and equipment used in our operations. As of June 30, 2025, we had future expected lease payment obligations totaling $9.3 million, with $2.2 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 Program was also extended and was effective until August 30, 2026. The authorization did not require the purchase of any minimum number of shares. On July 11, 2025, pursuant to the terms of the DoD Transaction Agreements, we terminated the Program. See the <u>["Recent Developments"](#i36e728074715429b91883a0ff85e6f7d_112)</u> section for additional information.

***Net Cash Used in Operating Activities:*** Net cash used in operating activities increased by $56.6 million for the six months ended June 30, 2025, as compared to the prior year period, driven primarily by the recognition of deferred revenue from sales of magnetic precursor products that began in the current year period and the increase in inventories to support the ramp of production of separated products and magnetic precursor products.

***Net Cash Provided by Investing Activities:*** Net cash provided by investing activities increased by $43.0 million for the six months ended June 30, 2025, as compared to the prior year period, primarily driven by lower additions to property, plant and equipment for the six months ended June 30, 2025, which decreased by $51.0 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 $12.2 million in proceeds from government awards used for construction that we received during the six months ended June 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. This was partially offset by lower net proceeds from maturities of short-term investments in the current year period for a net decrease in cash provided of $21.7 million.

***Net Cash Provided by (Used in) Financing Activities:*** Net cash used in financing activities was $7.7 million for the six months ended June 30, 2025, as compared to net cash provided by financing activities of $31.4 million in the prior year period. The change in cash flows from financing activities was driven by the net cash flow impact of $36.7 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, all of which occurred during the six months ended June 30, 2024.

**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:

&nbsp;&nbsp;&nbsp;&nbsp;(2)Included in "Start-up costs" within our unaudited Condensed Consolidated Statements of Operations and excludes any applicable stock-based compensation, which is included in the "Stock-based compensation expense" line above. Primarily relates to certain costs incurred in connection with the commissioning and starting up of our initial magnet-making capabilities at Independence prior to the achievement of commercial production. These costs include labor of incremental employees hired in advance to work directly on such commissioning activities, training costs, costs of testing and commissioning the new circuits and processes, and other related costs. Given the nature and scale of the related costs and activities, management does not view these as normal, recurring operating expenses, but rather as non-recurring investments to initially develop our 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 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.

The following table presents a reconciliation of our Free Cash Flow, which is a non-GAAP financial measure, to our net cash used in operating activities, which is determined in accordance with GAAP:

**ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

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 concentrate, separated NdPr oxide, 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. We have not entered into derivative contracts to protect the price of our products, and do not expect to do so in the foreseeable future, as there is no liquid market for such contracts and their cost may be prohibitive, if they could be obtained at all.

In July 2025, we entered into a series of agreements with the DoD, as part of which the DoD committed for a 10-year period, commencing on the first day of the fourth quarter of 2025, to provide us with quarterly payments (as needed) to guarantee a floor price for our NdPr products as described under <u>[Part I, Item 2, "Management's Discussion and Analysis of Financial Condition and Results of Operations—Recent Developments"](#i36e728074715429b91883a0ff85e6f7d_112)</u>. Additionally, the DoD agreed to purchase the entire quantity of magnets produced at our 10X Facility, which, upon completion, we expect will utilize as an input a substantial portion of the NdPr we produce. While this DoD commitment provides a meaningful measure of certainty with respect to our near- 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 DoD offtake commitment begins. Additionally, we continue to produce other rare earth products, which is required by our agreement with the DoD 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 monthly U.S. dollar REO prices with Shenghe, 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 DoD, including with respect to price protection 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

<u>[T](#i36e728074715429b91883a0ff85e6f7d_7)[able of Contents](#i36e728074715429b91883a0ff85e6f7d_7)</u>

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.

**ITEM 4. CONTROLS AND PROCEDURES**

The Company's management, under the supervision and with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")), as of June 30, 2025. Based on this evaluation, our principal executive officer and principal financial officer concluded that the Company's disclosure controls and procedures were effective as of June 30, 2025, to ensure that information required to be disclosed by the Company in reports we file or submit under the Exchange Act is (i) recorded, processed, summarized, evaluated and reported, as applicable, within the time periods specified in the U.S. Securities and Exchange Commission's rules and forms and (ii) accumulated and communicated to the Company's management, including the Company's principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosures.

There were no changes that occurred during the fiscal quarter covered by this Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**PART II—OTHER INFORMATION**

**ITEM 1. LEGAL PROCEEDINGS**

From time to time, we may be subject to legal and governmental proceedings and claims in the ordinary course of business. We are not currently a party to any material legal or governmental proceedings, and, to our knowledge, none is threatened.

**ITEM 1A. RISK FACTORS**

The Company's business, reputation, results of operations and financial condition, as well as the price of the Company's common stock, can be affected by a number of factors, whether currently known or unknown, including those described in Part I, Item 1A. "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2024 (the "Form 10-K") and in Part II, Item 1A. "Risk Factors" in our Form 10-Q for the quarterly period ended March 31, 2025. When any one or more of these risks materialize from time to time, the Company's business, reputation, results of operations and financial condition, as well as the price of the Company's common stock, can be materially and adversely affected. There have been no material changes to the risk factors disclosed in our Form 10-K and in our Form 10-Q for the quarterly period ended March 31, 2025, except as noted below.

***While we have executed the DoD Transaction Agreements with the United States Department of Defense and received funding thereunder, there can be no assurances that the authorization of and continued support for the transactions contemplated by the DoD Transaction Agreements will not be modified, challenged or impaired in the future, which would have a material adverse effect on our business, results of operations and financial position.***

In July 2025, we and the DoD executed the DoD Transaction Agreements and satisfied all conditions required thereunder, including the receipt by the Company of the proceeds from the sale of the Series A Preferred Stock. We have received assurances from the DoD that it has, pursuant to Title III of the Defense Production Act ("DPA"), 50 U.S.C. § 4531 et seq., as well as other authorities, all requisite authority to enter into the DoD Transaction Agreements and to consummate its obligations thereunder, including with respect to appropriation of the funds used to purchase the Series A Preferred Stock and to fund the Samarium Project Loan. However, given the unconventional use of DPA Title III authority, the need for the DoD to secure additional funds in the future in order to meet its obligations in these DoD Transaction Agreements, as well as the heightened sensitivity and complexity of contracting with a government entity, particularly in a high profile industry implicating national security, there can be no assurances that the authorization of and continued support for the DoD Transactions will not be modified, challenged or impaired in the future, which could have a material adverse effect on our business, results of operations and financial position and the price of our common stock. We believe there are multiple factors that may contribute to this uncertainty, including, but not limited to, the interpretation of current and future, and enactment of future, federal and

international laws, regulations, administrative actions and rulings, and interpretations and changes to interpretations thereof, whether by a court or within the legislative or executive branches of the federal government; our ability to comply with any conditions or other requirements imposed by such laws, regulations, actions and rulings, and changes thereto; a determination by the legislative, judicial, or executive branches of the federal government that any aspect of DoD Transaction Agreements was unauthorized, void, or voidable; future changes in federal administration and related executive and legislative priorities; the continued availability of Congressional appropriations and DoD funding; geopolitical developments; and the legal and strategic challenges associated with enforcing the obligations of and seeking performance from a government counterparty, especially in conjunction with the unique defenses and remedies available to the federal government. Furthermore, while the DoD is contractually bound under the DoD Transaction Agreements, no other agency, office or branch of the federal government has made any assurances or has any obligations under the DoD Transaction Agreements to actively support, accede to or refrain from challenging, investigating or otherwise impeding the commitments and obligations of the parties to the DoD Transaction Agreements, whether now or in the future. The DoD Transactions may also be challenged by other third parties and are subject to the risk of litigation, both the cost and result of which could materially adversely affect our business, prospects, financial condition and results of operations. The DoD Transaction Agreements contain affirmative covenants requiring us to take certain actions and negative covenants restricting our ability to take certain actions, which the failure to comply with could give rise to an event of default under the applicable DoD Transaction Agreements and if any such event of default is not waived by the DoD, the DoD would have the right to exercise certain remedies or damages including but not limited to termination of one or more of the DoD Transaction Agreements and/or acceleration of maturity of the Samarium Project Loan any of which could materially adversely affect our business, results of operations and financial position. Any of these adverse effects may also result in volatility in or adverse effects on the price of our common stock.

The DoD Transaction Agreements require the Company make substantial investments in and commitments to specific aspects of our business, namely the expansion of our midstream separation capabilities and development of our 10X Facility. Furthermore, under the terms of the DoD Offtake Agreement, we anticipate that the DoD will become our largest customer of magnets and that the obligations of the DoD under the PPA and DoD Offtake Agreement will represent a significant source of our revenue. As such, we will be heavily reliant upon the continued availability of financing provided by the DoD (including its ability to secure sufficient funding from the legislative branch), as well as the DoD's long-term pricing and offtake commitments in planning our operations and formulating our strategic plan. If for any reason contractually agreed to (but currently unavailable) funding is not timely appropriated by the legislative branch or otherwise becomes unavailable, reduced, restricted, or delayed, we may need to seek alternate financing arrangements, and there can be no assurance that we would be able to secure replacement financing on acceptable terms, at favorable pricing, in a timely manner or at all. If we are not successful in generating alternate financing from operations or in equity or debt capital raising transactions, we may need to reduce our costs, which measures could include selling or consolidating certain operations or assets, and delaying, canceling or scaling back our development projects. Further, historically, market prices for rare earth metals and their downstream products have been subject to a high degree of volatility. If the DoD were to fail to meet its obligations with respect to its pricing and offtake commitments, or to be delayed in doing so, our products may not be cost-optimized to compete in the market, and our profitability may be materially adversely impacted if we choose to offer our products at a reduced price. Additionally, because many of our products may be designed to satisfy DoD specifications and requirements, our products may not find customers in the commercial marketplace, and our profitability may be materially adversely impacted if we are unable to identify alternative sales channels. Failure by either or both of the Company and the DoD to perform its obligations under the PPA and DoD Offtake Agreement would have a material adverse impact on our business, prospects, results of operations and financial position, and may result in increased volatility in and an adverse effect on the price of our common stock.

Our operations are subject to extensive regulatory requirements enforced in part by the federal government. If government regulations are interpreted or enforced in a manner adverse to us, we may be subject to enforcement actions, penalties, exclusion, and other material limitations on our operations. Any change in our relationship with the federal government could impair our ability to operate our existing business and pursue our strategic plans. Furthermore, many of the potential opportunities presented by our strategic relationship with the DoD cannot be replaced, including the government's unique position to assist and facilitate our sourcing of heavy rare earth feedstock and securing necessary environmental permits and approvals, and with respect to the designation with the highest priority DX Rating under the Defense Priorities and Allocations System of our contracts relating to the DoD Transactions. In the event of any termination or frustration of the DoD Transaction Agreements, in full or in part, we may have limited recourse and remedies available against the DoD and the federal government.

The Company's agreement to the DoD Transaction Agreements also subjects it to various laws, regulations, and other policies and considerations that may constrain our future business or otherwise have a material adverse impact on future financial results. The Company may be subject to heightened scrutiny of our business activities with both government and non-government customers, government audits, investigations, congressional scrutiny, inquiries about conflicts of interest, civil or

<u>[T](#i36e728074715429b91883a0ff85e6f7d_7)[able of Contents](#i36e728074715429b91883a0ff85e6f7d_7)</u>

criminal enforcement by the Department of Justice (including actions under the False Claims Act), exclusion or limitation on future government-funded opportunities, suspension, debarment, and other administrative remedies.

***The DoD Transaction Agreements contain affirmative and negative covenants that may restrict our ability and the ability of our subsidiaries to take actions management believes are important to our long-term strategy, and therefore could have a material adverse effect on our business, prospects, financial condition, or results of operations.***

The DoD Transaction Agreements contain affirmative covenants requiring us to take certain actions and negative covenants restricting our ability to take certain actions. The affirmative covenants impose obligations on us with respect to, among other things, (i) constructing and developing the 10X Facility, (ii) expanding heavy rare earth elements ("HREE") refining capacity at Mountain Pass, to include, after the DoD extends the Samarium Project Loan to the Company in accordance with the DoD Transaction Agreements, the separation of samarium oxide, (iii) expanding/recommissioning the chlor-alkali facilities at Mountain Pass, and (iv) expanding capacity at the Independence Facility to a projected 3,000 metric tons of magnets annually. The negative covenants in the DoD Transaction Agreements restrict us with respect to, among other things, (i) consummating certain fundamental events other than to person(s) from certain permitted jurisdictions, (ii) selling any equity or material assets of the Project Company (as such term is defined in the DoD Offtake Agreement), (iii) selling assets or products identified by the DoD as a priority to U.S. national security interests, (iv) knowingly issuing more than 14.9% of the common stock to person(s) from foreign jurisdictions other than certain permitted jurisdictions, (v) consummating certain fundamental events subject to the jurisdiction of the Committee on Foreign Investment in the United States ("CFIUS") without obtaining CFIUS clearance prior to consummation or (vi) selling NdPr or magnets to any customer qualifying as a "Restricted Buyer" under the PPA or permitting any customer to resell NdPr or magnets to a Restricted Buyer (other than any NdPr or magnets that are included in another finished product sold by such customer).

Compliance with the affirmative and negative covenants contained in the DoD Transaction Agreements could restrict our ability to take actions that management believes are important to our long-term strategy. If strategic transactions we wish to undertake are prohibited by the DoD Transaction Agreements, our ability to execute our long-term strategy could be materially adversely affected.

***The conversion or exercise of the Series A Preferred Stock and the Warrant into shares of common stock would dilute the ownership of our common stock, and the subsequent sale of a substantial number of such shares of common stock in the public market, or the perception of such sales, could cause our stock price to fall.***

The shares of common stock into which the shares of Series A Preferred Stock are initially convertible and for which the Warrant is initially exercisable collectively represented 15% of the Company's issued and outstanding common stock prior to the DoD Transactions, without giving effect to the issuance of such shares. The Series A Preferred Stock and the Warrant are convertible and exercisable at any time and from time to time after the date that is 45 days after the closing of the DoD Transactions. Further, at any time after the five-year anniversary of the closing of the DoD Transactions, if the closing price of our common stock exceeds 150% of the then-current conversion price for at least twenty trading days in any period of thirty consecutive trading days, we will have the option to require all or any portion of the then-outstanding Series A Preferred Stock be converted into common stock at the then-current conversion price, subject to certain conditions. As such, existing common stockholders, including holders of shares of common stock offered hereby, may experience substantial dilution of their ownership positions.

Furthermore, the sale of a substantial number of shares of our common stock in the public market, or the perception that these sales might occur, including of the shares issuable upon conversion and exercise of the Series A Preferred Stock and the Warrant, could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that sales may have on the prevailing market price of our common stock.

***The financial, tax and accounting treatment of the DoD Transactions contemplated by the DoD Transaction Agreements remains uncertain and subject to change.***

Given both the novelty and complexity of the DoD Transactions, the Company's initial analysis of the financial, tax and accounting implications of its commitments and obligations under the DoD Transaction Agreements has not been completed and may take considerable time and require significant attention from management.

Additionally, no assurance can be provided that this initial assessment will not require adjustment or amendment over time due to changes in tax law or regulations, accounting practices and requirements and unforeseen developments in the course of providing services and receiving cash flows relating to the DoD Transactions, particularly with respect to the DoD Offtake Agreement and PPA, including with respect to the timing and characterization of payments received from the DoD, among

other considerations. The DoD Transaction Agreements are also highly integrated, and certain of the obligations under each DoD Transaction Agreement are contingent upon or impacted by the terms and obligations of the others. If one or more of the DoD Transaction Agreements, or one or more elements of the DoD Transactions, were to be altered, amended or terminated, management would need to assess the financial, tax and accounting implications of such changes, which could be significant, together with any related remedies available to the Company and the present condition of its business and operations. We are unable to predict and may not be able to anticipate either these changes or the impact thereof, which may have a material and adverse impact on our business and financial position, including, but not limited to, material changes to our financial outlook, recharacterizations or restatements of our financials or adjustments to previously provided estimates or guidance.

***Inability to perform the obligations under our customer supply agreements could have a material adverse effect on our financial position and results of operations.***

We have entered into the DoD Transaction Agreements with the DoD, including the DoD Offtake Agreement, and the supply agreement with Apple Inc. ("Apple"), and we previously entered into a binding long-term supply agreement with the General Motors Company ("GM"). Our ability to fulfill our obligations under these long-term agreements to supply the DoD, Apple and GM, as well as any other future customers, with magnets and magnet materials, are subject to a number of risks and contingencies. We are currently building the Independence Facility, the first scaled rare earth magnet manufacturing facility in the U.S. in several decades, and under the DoD Transaction Agreements, we are required to begin planning and constructing a second rare earth magnet manufacturing facility, the 10X Facility. While we are relying, and will rely, on a number of experienced engineers and other third parties in the design, engineering and construction of the Independence Facility and the 10X Facility, we are making and will be required to make a number of judgments and assumptions on process design, equipment selection and design, and plant operations, that may or may not prove to be correct. Design, engineering or construction delays may impair our ability to perform under our long-term agreements with the DoD, Apple and GM, as well as those made with any other future customers. We will also need to promptly assess the need for and to build out additional resources to support multiple novel construction projects in parallel. In addition, we need to procure the necessary equipment and materials to produce magnets and their precursor products, some of which may be difficult to obtain. There can be no assurance that such resources, equipment and materials will be procured on time or not be delayed due to both the finite time and resources of our management and employees to assess and respond to these increased demand, and to circumstances beyond our control.

Further, we need to hire a sufficient number of engineers, operators and other professionals to successfully design and operate the Independence Facility and the 10X Facility. It may be difficult for us to hire employees with the experience, education and skills needed to produce magnet materials, and we may need to hire employees from other countries if we cannot recruit employees in the U.S. We will also face competition for these employees. These challenges may be exacerbated by the need to develop multiple facilities at the same time.

There can be no assurance that we successfully produce magnet materials at the volumes and quality necessary to meet the requirements under our long-term supply agreements with the DoD, Apple and GM. In the event we are not able to mitigate these risks or fail to comply with the terms of the DoD Transaction Agreements, particularly the DoD Offtake Agreement, and our supply agreements with Apple and GM, we may experience material adverse effects on our financial position and results of operations.

## 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 June 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.
