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. The Company, which is headquartered in Las Vegas, Nevada, owns and operates the Mountain Pass Rare Earth Mine and Processing Facility (“Mountain Pass”), the only rare earth mining and processing site of scale in North ~~America. MP Materials currently~~America, and is constructing a rare earth metal, alloy and magnet manufacturing facility in Fort Worth, Texas (the “Fort Worth Facility”), where the Company anticipates manufacturing, among other products, neodymium-iron-boron (“NdFeB”) permanent magnets.

Currently, the Company primarily produces a rare earth concentrate that is principally sold pursuant to the Offtake Agreement to Shenghe (as such terms are defined in Note ~~13, “Related-Party~~15, “Related-Party Transactions ,”), a related party of the Company, that, in turn, typically sells that product to refiners in China. These refiners separate the constituent rare earth elements contained inwithin the ~~Company’s~~ concentrate and sell the separated products to their customers.

Upon completing initial commissioning of the remaining circuits of the Company’s Stage II optimization project (“Stage II”), in the third quarter of 2023, the Company ~~anticipates~~began producing ~~and selling~~ separated rare earth products, including neodymium-praseodymium (“NdPr”) ~~oxide,~~oxide. The Company anticipates selling these new products to customers ~~globally. In February~~in the U.S. and around the globe beginning in the fourth quarter of 2023, ~~the Company entered into~~including to Japanese customers pursuant to a distributorship agreement ~~(“Distribution Agreement”)~~ with Sumitomo Corporation of Americas (“Sumitomo”), under which Sumitomo will serve as the exclusive distributor of NdPr oxide produced by the Company to Japanese customers. Further, in connection with the Distribution Agreement, the Company and Sumitomo intend to collaborate on the supply of rare earth metals and other products..

In addition, the Company is constructing its initial rare earth metal, alloy and magnet manufacturing facility in Fort Worth, Texas (the “Fort Worth Facility”), where it anticipates manufacturing, among other products, neodymium-iron-boron (“NdFeB”) permanent magnets. Furthermore,Additionally, in April 2022, the Company entered into a long-term supply agreement with General Motors Company (NYSE: GM) (“GM”) to supply U.S.-sourced and manufactured rare earth materials, alloy and finished magnets for the electric motors in more than a dozen models using GM’s Ultium Platform, with a gradual production ramp that is expected to begin in late ~~2023, starting with alloy.~~2023. These developments are a part of the Company’s Stage III downstream expansion strategy (“Stage III”).

Operating segments are defined as components of an enterprise about which separate financial information is available and evaluated regularly by the chief operating decision maker (“CODM”), or decision-making group, in deciding how to allocate resources and in assessing performance. The Company’s CODM views the Company’s operations and manages the business as one reportable segment.

The cash flows and profitability of the Company’s operations are significantly affected by the market price of rare earth products. 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 capabilities of the region. 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. 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 ~~Annual Report on~~ Form ~~10-K for the year ended December 31, 2022.~~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~~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

T ~~able of Contents~~

(iii) the reported amounts of revenues and expenses during the reporting period. Accordingly, actual results may differ from those estimates.

T able of Contents

Concentration of Risk: Financial instruments that potentially subject the Company to credit risk consist principally of cash, cash equivalents and short-term investments, and trade accounts receivable. 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 ~~March 31,~~September 30, 2023, Shenghe was the Company’s principal customer and accounted for more than 90% of ~~product sales.~~revenue. 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”), as evidenced by the volatility experienced in 2022 and continued into 2023 due to concerns over the global economic conditions and actual or perceived concerns over increases in the supply of rare earth products. Furthermore, while revenue is generated in the ~~United States,~~U.S., Shenghe conducts its primary operations in China and may transport and sell products in the Chinese market. Therefore, the Company’s revenue is affected by Shenghe’s ultimate realized prices in China, including the impact of changes in the exchange rate between the Chinese Yuan and the U.S. dollar. In addition, there is an ongoing economic conflict between China and the ~~United States~~U.S. that has previously resulted in tariffs and trade barriers that may negatively affect the Company’s business and results of operations. See Note ~~13,~~15, “Related-Party Transactions,” for additional information.

~~The impact~~At the onset of the COVID-19 pandemic and ~~its effects continue to evolve. Since~~through 2022, the ~~onset of the pandemic, the~~ Company ~~has~~ experienced, at times, significant shipping delays due to congestion and slowdowns at U.S. and international ports caused by shortages in vessels, containers, and truckers, also disrupting the global supply chain. Despite these factors, the Company ~~has~~did not ~~experienced~~experience a reduction in production or sales due to the COVID-19 pandemic. However, the COVID-19 pandemic ~~has~~ contributed to certain cost and schedule pressures for capital ~~projects and may impact the reliability of transportation, particularly as the Company expects a significant increase in inbound logistics of raw materials to be consumed in Stage II operations.~~

projects. The Company continues to monitor the global situation, including the impacts of new and potential future variants of COVID-19, or other factors that may affect international shipping, logistics, and supply chain, or involve responses to government actions such as strikes or other disruptions. It

Intangible Assets: Indefinite-lived intangible assets are tested annually for impairment, or more frequently if events or changes in circumstances indicate that it is ~~impossible to predict~~more likely than not that the ~~effect and ultimate impact~~assets are impaired. If the carrying amounts of the ~~COVID-19 pandemic~~indefinite-lived intangible assets exceed their fair value, the excess amount is recognized as an impairment. Intangible assets that have a definite life are amortized on a straight-line basis over their estimated useful lives to reflect the expected pattern of economic benefits consumed. The Company reviews the carrying amount of its amortizing intangible assets for possible impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. If the carrying amounts of the amortizing intangible assets exceed their fair value, the excess amount is recognized as an impairment. Once an impairment of an intangible asset has been recorded, it cannot be reversed. No impairment charges were recorded during the three and nine months ended September 30, 2023 and 2022. See also Note 6, “Intangible Assets.”

Leases:The Company determines if an arrangement is, or contains, a lease at contract inception. In some cases, the Company has determined that its lease arrangements include both lease and non-lease components. The Company has elected to use a practical expedient to account for each separate lease component and its associated non-lease components as a single lease component for the majority of its asset classes. The Company recognizes right-of-use (“ROU”) assets and lease liabilities upon commencement for all leases with a lease term greater than 12 months. The Company has elected to use a practical expedient to not recognize leases with a lease term of 12 months or less in the unaudited Condensed Consolidated Balance Sheets for the majority of its asset classes. These short-term leases are expensed on a straight-line basis over the lease term.

ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at commencement date of the lease based on the ~~Company’s business, results~~present value of ~~operations, production~~lease payments over the lease term. When the rate implicit in the lease cannot be readily determined, the Company utilizes its incremental borrowing rate in determining the present value of the future lease payments. Lease liabilities are accreted each period and ~~sales volumes,~~reduced for payments. The ROU asset also includes other adjustments, such as for the effects of lease prepayments, initial lease costs, or ~~growth projects.~~lease incentives received. The lease term may include periods covered by options to extend or terminate the lease when it is either reasonably certain that the Company will exercise a renewal option, or reasonably certain it will not exercise an early termination option. For operating leases, lease expense is recognized on a straight-line basis over the lease term. For finance leases, the ROU asset amortizes on a straight-line basis over the shorter of the lease term or the useful life of the underlying asset (or the useful life of the underlying asset if title transfers at the end of the lease term or there is a purchase option the Company is reasonably certain to exercise) and the lease liability accretes interest based on the interest method using the discount rate determined at lease commencement. For operating and finance leases, variable lease payments not included in the lease liability are expensed as incurred unless such costs are capitalized as part of another asset (e.g., inventory). Additionally, ROU assets are subject to impairment testing whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. If the carrying amounts of ROU

T able of Contents

assets exceed their fair value, the excess amount is recognized as an impairment. No impairment charges were recorded during the three and nine months ended September 30, 2023 and 2022. See also Note 9, “Leases.”

Stock-Based Compensation: The cost of employee services received in exchange for an award of equity instruments is based on the grant-date fair value of the award. The fair value of Stock Awards (as defined in Note ~~10,~~12, “Stock-based Compensation,”) is equal to the fair value of the Company’s stock on the grant date. The fair value of performance awards that include performance and/or market conditions is determined using a Monte Carlo simulation technique. The Monte Carlo simulation requires the use of inputs and assumptions such as the grant-date closing stock price, expected volatility, correlation coefficient to relevant peer groups or indices, risk-free interest rate and dividend yield.

Compensation cost for Stock Awards with graded vesting schedules is recognized on a straight-line basis over the requisite service period for each separately vesting portion of the award as if the award was, in substance, multiple awards, which results in accelerated recognition of compensation cost. Compensation cost for performance awards with cliff vesting schedules is recognized on a straight-line basis over the requisite service period. Compensation cost is not adjusted based on the actual achievement of the market-based performance goals. The Company accounts for forfeitures in the period in which they occur based on actual forfeitures. See also Note ~~10,~~12, “Stock-based Compensation.”

Recently Issued Accounting Pronouncements: During the three and nine months ended ~~March 31,~~September 30, 2023, there were no accounting pronouncements adopted by the Company that had a material impact on the ~~Company's~~Company’s unaudited Condensed Consolidated Financial Statements. Additionally, as of ~~March 31,~~September 30, 2023, there were no accounting pronouncements pending adoption that are expected to have a material impact on the Company's unaudited Condensed Consolidated Financial Statements.

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

The Company does not intend to sell, nor is it more likely than not that the Company will be required to sell, any investments in unrealized loss positions before recovery of their amortized cost basis. The Company did not recognize any credit losses related to its available-for-sale investments during the three and nine months ended ~~March 31, 2023.~~September 30, 2023 and 2022. 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 ~~March 31,~~September 30, 2023, 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.

NOTE 6—INTANGIBLE ASSETS

In August 2023, the Company acquired a license to use patented technology, technical know-how, and other intellectual property pertaining to the development and manufacturing of magnetics products in exchange for 435,729 shares of the Company’s common stock. Pursuant to the terms of the agreement to acquire the license, 152,504 shares were issued immediately and the remaining shares will be issued as follows: 43,573 on each of the first, second, and third anniversaries of the acquisition date and an additional 152,506 shares on the fourth anniversary of the acquisition date.

Upon obtaining the license, the Company recorded a definite-lived intangible asset in the amount of $9.0 million, based on the closing price of the Company’s common stock on the acquisition date. The intangible asset will be amortized on a straight-line basis, with no estimated residual value, over the estimated useful life of 7.5 years, which the Company based on the life of the patents associated with the licensed technology.

T able of Contents

Contemporaneous with the acquisition of the license, the Company entered into a consulting agreement in support of integrating the licensed technology and know-how into its existing processes aimed at the development of magnetics products. Unless earlier terminated, under the consulting agreement, the Company will pay a total of approximately $15 million over the next four years, of which, the first payment will be in cash on the first anniversary of the consulting agreement and the payments pertaining to the second, third, and fourth anniversaries of the consulting agreement may be settled in cash or shares of the Company’s common stock at the Company’s election. The Company will ratably record an expense over the four-year period unless the costs qualify for capitalization.

NOTE 6—7—ASSET RETIREMENT AND ENVIRONMENTAL OBLIGATIONS

Asset Retirement Obligations

The Company estimates asset retirement obligations based on the requirements to reclaim certain land areas associated with mineral extraction activities and certain related facilities at Mountain Pass. Minor reclamation activities related to discrete portions of the Company’s operations are ongoing. As of September 30, 2023, 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 2056 and 2057.

In June 2021, San Bernardino County approved a re-zoning request for certain of the Company’s properties such that certain of the Company’s processing and separations facilities would be zoned for industrial end uses as opposed to the prior “resource conservation” designation. In September 2022, and as a result of the re-zoning of this land, the Company received final approval from San Bernardino County and the Division of Mine Reclamation (California) on a revised reclamation plan. The revision removed from the regulatory oversight under The Surface Mining and Reclamation Act of 1975 the majority of the buildings and equipment used in the processing and separations facilities, including the land underlying such buildings and equipment.

As a result of the final approval of the reclamation plan, in the third quarter of 2022, the Company revised its estimated cash flows pertaining to the settlement of the reclamation and removal activities associated with Mountain Pass, including removing the previous estimates of the cash flows associated with the processing and separations facilities that no longer

T able of Contents

require reclamation. The changes in estimates resulted in an asset retirement obligation decrement of $13.1 million, of which $10.4 million reduced the carrying amounts of the associated property, plant and equipment, and $2.7 million, reflecting the excess of the decrement over the carrying amount of the related property, plant and equipment, was recorded as a reduction to depreciation expense for the three and nine months ended September 30, 2022.

As of September 30, 2023, the credit-adjusted risk-free rate ranged between 6.5% and 12.0% depending on the timing of expected settlement and when the increment was recognized. There were no significant increments or decrements for the three and nine months ended September 30, 2023, and there were no significant increments for the three and nine months ended September 30, 2022.

The balance as of both September 30, 2023, and December 31, 2022, included current portions of $0.2 million, which are included in “Other current liabilities” within the Company’s unaudited Condensed Consolidated Balance Sheets. The total estimated future undiscounted cash flows required to satisfy the Company’s asset retirement obligations were $50.3 million and $50.4 million as of September 30, 2023, and December 31, 2022, respectively.

Environmental Obligations

The Company has certain environmental remediation liabilities related to the monitoring of groundwater contamination. The Company engaged an environmental consultant to develop a remediation plan and remediation cost projections based upon that plan. Utilizing the remediation plan developed by the environmental consultant, the Company developed an estimate of future cash payments for the remediation plan.

As of September 30, 2023, the Company estimated the cash outflows related to these environmental activities will be incurred annually over the next 24 years. The Company’s environmental remediation liabilities are measured at the expected value of future cash outflows discounted to their present value using a discount rate of 2.93%. There were no significant changes in the estimated remaining remediation costs for the three and nine months ended September 30, 2023 and 2022.

The total estimated aggregate undiscounted cost of $26.8 million and $27.2 million as of September 30, 2023, and December 31, 2022, respectively, principally related to water monitoring 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 balance as of both September 30, 2023, and December 31, 2022, included current portions of $0.5 million, which are included in “Other current liabilities” within the Company’s unaudited Condensed Consolidated Balance Sheets.

Financial Assurances

The Company is required to provide the applicable government agencies with financial assurances relating to the closure and reclamation obligations. As of September 30, 2023, and December 31, 2022, the Company had financial assurance requirements of $45.4 million and $43.5 million, respectively, which were satisfied with surety bonds placed with California state and regional agencies.

NOTE 8—10—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 ~~taxes~~tax expense or benefit as a percentage of income or loss before income taxes) including discrete items was ~~17.3%~~4.5% and 24.5% for the three and nine months ended ~~March 31,~~September 30, 2023, respectively, as compared to 24.9% and 24.5% for the three and nine months ended September 30, 2022, 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, and changes to its valuation allowance against deferred tax assets. Certain of these and other factors, including the Company’s history and projections of pretax earnings, are considered in assessing its ability to realize its net deferred tax assets.

			Level 11:			Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

			Level 22:			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.

T ~~able of Contents~~

Level 33:

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, short-term debt 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.

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 Company’s equipment notes are classified within Level 2 of the fair value hierarchy because there are inputs that are directly observable for substantially the full term of the liability. 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 ~~12—~~14—EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per share ~~(“EPS”)~~ is computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the period. Diluted ~~EPS~~earnings (loss) per share is computed by dividing net income (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.

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

NOTE ~~13—~~15—RELATED-PARTY TRANSACTIONS

Offtake Agreement: In March 2022, the Company entered into an offtake agreement (the “Offtake Agreement”) with Shenghe Resources (Singapore) International Trading Pte. Ltd. (“Shenghe”), a majority-owned subsidiary of Leshan Shenghe

T ~~able of Contents~~

Rare Earth Co., Ltd. (“Leshan Shenghe”) whose ultimate parent is Shenghe Resources Holding Co., Ltd., a leading global rare earth company listed on the Shanghai Stock Exchange. The Offtake Agreement became effective upon the termination of the ~~A&R Offtake Agreement (as discussed~~amended and ~~defined below).~~restated offtake agreement with Shenghe. The initial term of the Offtake Agreement is two years, with the option to extend the term at the Company’s discretion for an additional one-year period.

Pursuant to the Offtake Agreement, and subject to certain exclusions, Shenghe is 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 may be required to purchase on a “take or pay” basis certain non-concentrate rare earth products, although the Company may sell all non-concentrate rare earth products in its sole discretion to customers or end users in any jurisdiction. ~~Under the Offtake Agreement, Shenghe will be paid a variable commission on net proceeds to the Company.~~

The sales price of rare earth concentrate sold to Shenghe is based on an agreed-upon price per metric ton, subject to certain quality adjustments depending on the measured characteristics of the product, with an adjustment for the ultimate market price of the product realized by Shenghe upon sales to their customers. The sales price and other terms applicable to a quantity of offtake products are set forth in monthly purchase agreements between the Company and Shenghe. Under the Offtake Agreement, Shenghe is paid a variable commission on net proceeds to the Company.

Tolling Agreement with ~~VREX:~~VREX Holdco: In ~~March~~October 2023, the Company entered into a tolling agreement with VREX Holdco Ltd. Pte.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of financial condition, results of operations, liquidity and capital resources should be read in conjunction with, and is qualified in its entirety by, the unaudited Condensed Consolidated Financial Statements and the notes thereto included in this Quarterly Report on Form 10-Q (“Form 10-Q”), and the Consolidated Financial Statements and notes thereto and Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in the Annual Report on Form 10-K ~~(“Form 10-K”)~~ for the year ended December 31, ~~2022.~~2022 (“Form 10-K”). 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 “Part II. Item 1A. Risk Factors” and elsewhere in this Form 10-Q and “Part I. Item 1A. Risk Factors” and elsewhere in our Form 10-K. See also “Cautionary Note Regarding Forward-Looking Statements.”

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”), the only rare earth mining and processing site of scale in North ~~America. We currently~~America, and are also constructing a rare earth metal, alloy and magnet manufacturing facility in Fort Worth, Texas (the “Fort Worth Facility”), where we anticipate manufacturing, among other products, neodymium-iron-boron (“NdFeB”) permanent magnets.

Currently, we primarily produce a rare earth concentrate that is principally sold pursuant to the Offtake Agreement to Shenghe (as such terms are defined in Note ~~13,~~15, “Related-Party Transactions,” in the notes to the unaudited Condensed Consolidated Financial Statements), that, in turn, typically sells that product to refiners in China. These refiners separate the constituent rare earth elements (“REE”) contained in our concentrate and sell the separated products to their customers.

Upon completing initial commissioning of the remaining circuits of our Stage II optimization project (“Stage II”), in the third quarter of 2023, we ~~anticipate~~began producing ~~and selling~~ separated rare earth products, including neodymium-praseodymium (“NdPr”) oxide. ~~In addition, we are constructing our initial rare earth metal, alloy~~We anticipate selling these new products to customers in the U.S. and ~~magnet manufacturing facility~~around the globe beginning in ~~Fort Worth, Texas (the “Fort Worth Facility”~~the fourth quarter of 2023, including to Japanese customers pursuant to a distributorship agreement with Sumitomo Corporation of Americas (“Sumitomo”)~~, where we anticipate manufacturing, among other products, neodymium-iron-boron (“NdFeB”) permanent magnets. Furthermore,~~.

Additionally, in April 2022, we entered into a long-term supply agreement with General Motors Company (NYSE: GM) (“GM”) to supply U.S.-sourced and manufactured rare earth materials, alloy and finished magnets for the electric motors in more than a dozen models using GM’s Ultium Platform, with a gradual production ramp that is expected to begin in late ~~2023, starting with alloy.~~2023. These developments are a part of our Stage III downstream expansion strategy (“Stage III”).

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

Recent Developments and Other Information

Distribution Agreement with Sumitomo

In February 2023, we entered into a distributorship agreement (“Distribution Agreement”) with Sumitomo, ~~Corporation of Americas (“Sumitomo”),~~ under which Sumitomo ~~will~~would serve as the exclusive distributor of NdPr oxide, produced by us, to Japanese customers. Further, in connection with the Distribution Agreement, we intend to collaborate with Sumitomo on the supply of rare earth metals and other products. Under the terms of the Distribution Agreement, Sumitomo will be paid a variable commission. The initial term of the Distribution Agreement is through the end of 2025 with options to renew annually.

Patent and Intellectual Property License

In August 2023, we acquired a license to use patented technology, technical know-how, and other intellectual property pertaining to the development and manufacturing of magnetics products in exchange for 435,729 shares of our common stock. Contemporaneous with the acquisition of the license, we entered into a consulting agreement in support of integrating the licensed technology and know-how into its existing processes aimed at the development of magnetics products.

COVID-19 Pandemic

~~The impact~~At the onset of the COVID-19 pandemic and ~~its effects continue to evolve. Since the onset of the pandemic,~~through 2022, we ~~have~~ experienced, at times, significant shipping delays due to congestion and slowdowns at U.S. and international ports caused by shortages in vessels, containers, and truckers, also disrupting the global supply chain. Despite these factors, we ~~have~~did not ~~experienced~~experience a reduction in production or sales due to the COVID-19 pandemic. However, the COVID-19 pandemic ~~has~~ contributed to certain cost and schedule pressures for capital ~~projects, and may impact reliability of transportation, particularly as we expect a significant increase in inbound logistics of raw materials to be consumed in our Stage II operations.~~

projects. We continue to monitor the global situation, including the impacts of new and potential future variants of COVID-19, or other factors that may affect international shipping, logistics, and supply chain, or involve responses to government actions such as strikes or other disruptions. ~~It is impossible to predict the effect and ultimate impact of the COVID-19 pandemic on our business, results of operations, production and sales volumes, or growth projects.~~

Key Performance Indicators

We have historically used and/or currently use the following key performance indicators (“KPIs”) to evaluate the performance of our business. However, as weour business continues to evolve ~~as a business~~ and ~~transition~~transitions from a producer of rare earth concentrate to a producer of separated rare earth products, ~~upon completing the commissioning of our Stage II project,~~ the metrics that management ~~anticipates using~~uses to evaluate the business may continue to change or be revised. For example, in completing the transition to separated rare earth products, we may determine that production cost per rare earth oxide (“REO”) equivalent metric ton (“MT”), which is a metric focused solely on Stage I concentrate operations, is no longer meaningful in evaluating and understanding our business or operating results. In addition, during the third quarter of 2023, upon the production of separated products, we identified two new KPIs of our business: NdPr Production Volume and NdPr Sales Volume. Our calculations of these ~~performance indicators~~KPIs may differ from similar measures published by other companies in our industry or in other industries. The following table presents our ~~key performance indicators:~~KPIs:

REO Production Volume

We measure our REO-equivalent production volume for a given period in MTs, our principal unit of ~~sale.~~sale for our concentrate product. This measure refers to the REO content contained in the rare earth concentrate we ~~produce.~~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 NdPr product, the latter of which is also included in our KPI, NdPr Production Volume. Our REO ~~production volume~~Production Volume is a key indicator of our mining and concentrate processing capacity and efficiency. ~~Our REO production volume for the three months ended March 31, 2023, included certain concentrate that is stored in bulk silos as mechanically dried and/or roasted concentrate.~~

T able of Contents

The rare earth concentrate ~~we currently produce~~ is a processed, concentrated form of our mined rare earth-bearing ores. While our unit of production and sale is a MT of embedded 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~~Sales Volume for a given period is calculated in MTs. A unit, or MT, is considered sold ~~for purposes of this key performance indicator~~ 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~~Sales Volume is a key measure of our ability to convert our concentrate production into revenue. Our REO ~~sales volume~~Sales Volume for the three and nine months ended ~~March 31,~~September 30, 2023, included both traditional concentrate as well as roasted concentrate.

Realized Price per REO MT

We calculate the ~~realized price~~Realized Price per REO MT for a given period as the quotient of: (i) our ~~product~~rare earth concentrate sales, which isare determined in accordance with GAAP, for a given period and (ii) our REO ~~sales volume~~Sales Volume for the same period.

T ~~able of Contents~~

REO MT is an important measure of the market price of our concentrate product. Historically, we used Total Value Realized, which was a non-GAAP financial measure defined as our rare earth concentrate sales (previously captioned as product ~~sales~~sales) adjusted for the revenue impact of tariff rebates related to prior period sales, as the numerator in the calculation of ~~realized price~~Realized Price per REO MT. As we no longer expect to receive any additional tariff rebates, we no longer utilize Total Value Realized in the calculation of ~~realized price~~Realized Price per REO MT.

Production Cost per REO MT

We calculate the ~~production cost~~Production Cost per REO MT for a given period as the quotient of: (i) our Production Costs (see below) for a given period and (ii) our REO ~~sales volume~~Sales Volume for the same period. We define Production Costs, which is a non-GAAP financial measure, as our cost of sales (excluding depletion, depreciation and amortization) less stock-based compensation expense included in cost of sales, shipping and freight costs, and costs not attributable to ~~certain other~~concentrate sales.

Production ~~cost~~Cost per REO MT is a key indicator of our concentrate production efficiency. As a significant portion of our cash costs of Stage I production are fixed, our ~~production cost~~Production Cost per REO MT is influenced by mineral recovery, REO grade, plant feed rate and production uptime. See the “Non-GAAP Financial Measures” section below for a reconciliation of our Production Costs, which is a non-GAAP financial measure, to our cost of sales (excluding depletion, depreciation and amortization), which is determined in accordance with GAAP, as well as the calculation of ~~production cost~~Production Cost per REO MT.

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 our separating and finishing capacity and efficiency.

NdPr Sales Volume

Our NdPr Sales Volume for a given period is calculated in MTs and on an NdPr oxide-equivalent basis (see example below). A unit, or MT, is considered sold once we recognize revenue on its sale, whether sold as NdPr oxide or NdPr metal, as determined in accordance with GAAP. For NdPr metal sales, the MTs sold and included in NdPr Sales Volume are calculated on the basis of the volume of NdPr oxide used to produce such NdPr metal. For example, assuming a material conversion ratio of 1.25, a sale of 100 MTs of NdPr metal would be included in this KPI as 125 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.

We expect to have a mix of contracts with customers where we will 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.

Factors Affecting Our Performance

We believe we are uniquely positioned to capitalize on the key trends of electrification and supply chain security, particularly as domestic EV production grows. 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 ~~driver~~drivers for REE ~~is their use in~~are a diverse array of growing end markets, including clean-energy and transportation technologies, consumer and medical applications, critical defense systems, and essential industrial infrastructure. WeDespite the current macroeconomic conditions, we continue to believe we benefit from the ~~continued~~ 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; geographic supply chain diversification, particularly in relation to China; the U.S. government initiatives to restore domestic supply of key minerals; and the increasing acceptance of environmental, social and governance mandates.

However, changes in technology could also drive down 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. Such actual, or perceived, decreases in demand for 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, and many of our key competitors are based in China, where competitors may not be subject to the same rigorous environmental standards and production costs are typically lower than in the ~~United States.~~U.S.

Maximizing Production Efficiency

~~In 2022, REO production remained 3.5x greater than the highest production in a twelve-month period achieved at Mountain Pass by the former operator prior to~~Since the implementation of our Stage ~~I. This was~~I optimization plan and the achievement of commercial production on July 1, 2019, our quarterly REO Production Volume has exceeded 8,500 MTs, and we have achieved at least 10,000 MTs of REO Production Volume every quarter since the second quarter of 2021. These results were achieved by optimizing the reagent scheme, reducing process temperatures, improving tailings facility management, and committing to operational excellence, ~~that~~which has allowed us to sustain approximately 95% uptime. Our Stage I optimization ~~project~~plan enabled us to achieve what we believe to be world-class production cost levels for rare earth concentrate.

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

We currently operate 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. In addition, several of our current and potential competitors are government supported and may have access to substantially more capital, which may allow them to make similar or greater efficiency improvements or undercut market prices for our product.

Development of Our REE Refining, Metal Alloy, and Magnet-Making Capabilities

Stage II advances our operations from the production of rare earth concentrate to the separation of individual REE. The project incorporated upgrades and enhancements to the prior facility process flow to reliably produce separated REE at a low cost and with the intent of 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. ~~Significant commissioning activities commenced in~~During the ~~fourth quarter of 2022 beginning with the concentrate drying and roasting circuits, and continued into the first~~third quarter of 2023, ~~with most~~we began producing separated rare earth products. We expect that it may take up to several quarters to achieve our designed throughput of ~~the remaining circuits. Upon reaching run-rate~~separated products. As we increase production of ~~REE in Stage II,~~separated products over time, we expect to ~~be a global low-cost, high-volume producer~~improve our per-unit costs of NdPr oxide, which represents a majority of the value contained in our concentrate.

Partially supported by a $35.0 million award from the Department of Defense’s Office of Industrial Base Policy, Industrial Base Analysis and Sustainment program, we are currently advancing the facilitating works, engineering and procurement on a processing and separations facility for heavy rare earth elements (“HREE”) (the “HREE Facility”), which will be built at Mountain Pass and will be integrated into the rest of our Stage I and Stage II facilities. The HREE Facility is expected to support the separating of HREE contained in the Mountain Pass ore as well as from third-party feedstocks.

T able of Contents

In addition, we are ~~currently~~ constructing the Fort Worth Facility, and developing engineering and manufacturing technology to process NdPr oxide into metal alloys and magnets, while incorporating magnet recycling capabilities. These initiatives support our long-term plans to become a leading global source for rare earth magnets. We believe integration into magnet production will provide some protection from commodity pricing volatility, while also enhancing our business profile as the producer of a critical industrial output in addition to a producer of resources. We expect our Stage III efforts to continue to benefit from geopolitical developments, including initiatives to repatriate critical materials supply chains.

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, 2022, SRK Consulting (U.S.), Inc., an independent consulting firm that we retained to assess our reserves, estimated total proven and probable reserves of 1.96 million short tons of REO contained in 29.30 million short tons of ore at Mountain Pass, with an average ore grade of 6.32%. These estimates use an estimated economical cut-off of 2.49% total rare earth oxide. Based on these estimated reserves and our expected annual production, ~~rate of REO upon completing the commissioning of Stage II,~~ our expected mine life was approximately 34 years as of December 31, 2022. 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 ~~United States~~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.

Revenue consists primarily of ~~product sales, which pertain to our~~ sales of rare earth concentrate, including roasted concentrate, principally to Shenghe under the amended and restated offtake agreement (“A&R Offtake Agreement”) for sales between January 2022 and February 2022, or the Offtake Agreement for sales beginning in March 2022. The sales price of rare earth concentrate sold to Shenghe under both agreements is based on an agreed-upon price per MT, subject to certain quality adjustments depending on the measured characteristics of the product, 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.

The ~~decrease~~decreases in ~~product~~rare earth concentrate sales for the three and nine months ended ~~March 31,~~September 30, 2023, as compared to the respective prior year ~~period, was~~periods, were driven by lower ~~realized price~~Realized Price per REO MT, which decreased by ~~32%~~51% and 46%, ~~and~~respectively, when compared to the respective prior year periods, as well as lower REO ~~sales volume,~~Sales Volume, which decreased by ~~13%.~~ 14% and 8%, respectively, when compared to the respective prior year periods.

Historically, given our take-or-pay offtake arrangement with Shenghe, our REO ~~sales volume~~Sales Volume has generally tracked our REO ~~production volumes~~Production Volume over time despite period-to-period differences caused by the timing of shipments. However, as we

~~accelerate commissioning activities for Stage II,~~separated rare earth materials, we expect that significant volumes of REO produced from Stage I operations will be retained for separation ~~rather than~~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, as evidenced in the third quarter of 2023, we expect that REO Sales Volume will be significantly lower than REO Production Volume. See also the “Quarterly Performance Trend” section below.

The decrease in other rare earth product sales for the ~~three~~nine months ended ~~March 31,~~September 30, 2023, as compared to the prior year period, was driven by ~~$4.1~~$8.5 million of revenue related to a sales agreement with Shenghe entered into in March 2022 for certain stockpiles of rare earth fluoride.

Cost of sales (excluding depreciation, depletion and amortization) consists of production- and processing-related labor costs (including wages and salaries, benefits, and bonuses), mining and processing supplies (such as reagents), parts and labor for the maintenance of our mining fleet and processing facilities, other facilities-related costs (such as property taxes and utilities), packaging materials, and shipping and freight costs.

Cost of sales for the three months ended ~~March 31,~~September 30, 2023, ~~increased~~remained relatively flat year over year, primarily due to an increase in ~~production cost~~Production Cost per REO MT of $367 or 22%, offset by a decrease in REO Sales Volume and $1.9 million in lower shipping and freight costs, which are included in cost of sales but excluded from ~~$1,594 for the three months ended March 31, 2022, to $1,978 for the three months ended March 31, 2023.~~Production Cost per REO MT. The increase in ~~production cost~~Production Cost per REO MT was ~~principally~~ driven by higher payroll costs, including the ~~continued~~ increase in employee headcount to support the expansion of operations, and to a lesser extent, higher materials and supplies costs. Shipping and freight costs decreased primarily due to year-over-year declines in trucking rates and diesel fuel prices.

Cost of sales for the nine months ended September 30, 2023, increased year over year, primarily due to an increase in Production Cost per REO MT of $316 or 19%, which ~~increased slightly.~~was driven by higher payroll costs, including the increase in employee headcount to support the expansion of operations, and to a lesser extent, higher materials and supplies costs. The increase in cost of sales was partially offset by ~~lower year-over-year REO sales volume, and~~$4.4 million in lower shipping and freight costs ~~which are included in cost of sales but excluded from production cost per REO MT.

year-over-year declines in trucking rates and diesel fuel prices. Production ~~cost~~Cost per REO MT varies period to period based on the timing of scheduled outages of our production facilities for maintenance. See also the “Quarterly Performance Trend” section below.

Selling, general and administrative expenses consist primarily of accounting, finance and administrative personnel costs, including stock-based compensation expense related to these personnel; professional services (including legal, regulatory, audit and others); certain engineering expenses; insurance, license and permit costs; facilities rent and other costs; office supplies; general facilities expenses; and certain environmental, health, and safety expenses.

The increases in selling, general and administrative expenses were primarily due to ~~the prior year period due primarily to the accelerated recognition of stock-based compensation on virtually all of our stock awards. This decrease was offset by year-over-year increases in~~higher personnel costs (other than stock-based compensation expense), which increased ~~$1.7~~by $2.1 million and $4.9 million, respectively, along with other general and administrative costs required to further build out our corporate infrastructure in support of our downstream expansion. The increases in selling, general and administrative expenses were partially offset by $1.7 million and $7.1 million decreases in stock-based compensation expense for the three and nine months ended September 30, 2023, respectively, when compared to the respective prior year periods, due primarily to the timing of grants and the recognition of stock-based compensation on an accelerated basis for virtually all of our stock awards.

Advanced projects, start-up, development and other consists principally of ~~costs incurred in connection with research and development of new processes or to significantly enhance our existing processes;~~ start-up costs associated with restarting an existing facility or commissioning a new facility, circuit or process of our production, manufacturing, or separations facilities prior to achievement of commercial production; costs incurred in connection with research and development of new processes or to significantly enhance our existing processes; as well as costs incurred to support growth initiatives or pursue other opportunities.

Advanced projects, start-up, development and other for the three and nine months ended ~~March 31,~~September 30, 2023, increased year over year by $7.6 million and $19.5 million, respectively, which was primarily ~~due to a $3.2~~driven by $5.9 million ~~increase~~and $12.3 million, respectively, in higher start-up costs, ~~which primarily~~that predominantly relate to certain costs that do not qualify for capitalization, such as salaries and wages, outside services, parts, and training, used or consumed directly in the commissioning and starting up of our Stage II circuits and facilities that ~~are~~were not yet in commercial production. The remaining ~~increase~~increases primarily ~~relates~~relate to costs incurred to support growth initiatives or pursue other opportunities.

Depreciation, depletion and amortization primarily consists of depreciation of property, plant and equipment and depletion of mineral rights. The year-over-year increase in depreciation, depletion and amortization for the three and nine months ended ~~March 31,~~September 30, 2023, primarily reflects an increase in depreciation of ~~$3.1~~$14.6 million and $24.7 million, respectively, resulting from the continued placement of ~~several~~ new circuits and facilities associated with our Stage II optimization project into service, which began at the end of the fourth quarter of 2022.

Accretion of asset retirement and environmental obligations is based on the estimated future cash flows required to reclaim certain land areas associated with mineral extraction activities and certain related facilities at Mountain Pass and to monitor groundwater contamination, respectively. Accretion of asset retirement and environmental obligations for the three and nine months ended ~~March 31,~~September 30, 2023, decreased year over year primarily as a result of a ~~significant~~ decrement to our asset retirement obligation during the third quarter of 2022, which reduced the accretion of our asset retirement obligation in subsequent periods.

Loss on ~~sale or disposal~~disposals of long-lived assets, net consists of gains or losses on the ~~sale or disposal~~disposals of property, plant and equipment, as well as demolition costs. The year-over-year increase in loss on ~~sale or disposal~~disposals of long-lived assets, net, for the three and nine months ended ~~March 31,~~September 30, 2023, principally relates to demolition costs incurred in connection with demolishing and removing certain out-of-use older facilities and infrastructure from the Mountain Pass site to accommodate future expansion in rare earth processing.

Interest expense, net principally consists of expense associated with the 0.25% per annum interest rate and amortization of the debt issuance costs on our Convertible Notes (as defined in the “Liquidity and Capital Resources” section below) and amortization of the discount on a previous debt obligation to Shenghe, offset by ~~interest capitalized.~~capitalized interest. Interest expense, net for the ~~three~~nine months ended ~~March 31,~~September 30, 2023, decreased year over year due to the full repayment of the debt obligation to Shenghe in the first quarter of 2022.

Other income, net consists of interest and investment income and non-operating gains or losses. Other income, net for the three and nine months ended ~~March 31,~~September 30, 2023, increased year over year as a result of interest and investment income earned on our short-term investments, which were purchased starting in the second quarter of 2022. Interest and investment income is principally generated from accretion of the discount on such investments.

Income tax expense 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 (income ~~taxes~~tax expense as a percentage of income ~~or loss~~ before income taxes) was ~~17.3%~~4.5% and 24.5% for the three and nine months ended ~~March 31,~~September 30, 2023, respectively, as compared to 24.9% and 24.5% for the three and nine months ended September 30, 2022, respectively. The effective tax rate for the three and nine months ended ~~March 31,~~September 30, 2023, differed from the statutory tax rate of 21% primarily due to ~~excess~~state income tax ~~benefits associated with stock-based compensation.~~expense and a deduction limitation on officers’ compensation, offset by the Section 45X Advanced Manufacturing Production Credit

and the California Competes Tax Credit (“CCTC”). The effective tax rate for the three and nine months ended ~~March 31,~~September 30, 2022, differed from the statutory tax rate of 21% primarily due to state income tax expense and a deduction limitation on officers’ compensation, partially offset by the ~~California competes tax credit awarded to us in the fourth quarter of 2021.~~CCTC.

On August 16, 2022, the U.S. government enacted the Inflation Reduction Act of 2022 which, among other things, implements a 15% minimum tax on book income of certain large corporations, a 1% excise tax on net stock repurchases, and provides several tax incentives to promote clean energy for tax years beginning after December 31, 2022. We do not expect the minimum tax or excise tax to have a material impact on our unaudited Condensed Consolidated Financial Statements. We expect to benefit from the Section 45X Advanced Manufacturing Production Credit, which provides a credit equal to 10% of the costs incurred with respect to the production and sale of certain critical minerals, including NdPr oxide.

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. In addition, quarterly production is impacted by the timing of scheduled outages of our production facilities for maintenance, which typically occur in the second and fourth ~~quarter.~~ quarters. Finally, starting in the third quarter of 2023, as we ramp up production of separated rare earth materials, we expect that significant volumes of REO produced will be retained for separation and not sold as concentrate.

As noted above, as we evolve as a business and transition from a producer of rare earth concentrate to a producer of separated rare earth products, the metrics that management anticipates using to evaluate the business may change or be revised.

Liquidity and Capital Resources

Liquidity refers to our ability to generate sufficient cash flows to meet the cash requirements of our business operations, including working capital and capital expenditure needs, contractual obligations, debt service and other commitments. In recent years, our principal sources of liquidity have been financing through the consummation of the business combination with Fortress Value Acquisition Corp. in November 2020, the issuance of the Convertible Notes in March 2021, and net cash from operating activities. As of ~~March 31,~~September 30, 2023, we had ~~$1,169.0~~$1,084.7 million of cash, cash equivalents and short-term investments and $690.0 million principal amount of long-term debt.

T ~~able of Contents~~

Our results of operations and cash flows depend in large part upon the market prices of REO and particularly the price of rare earth concentrate. 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. Although we believe that our cash flows from operations and cash on hand are adequate to meet our liquidity requirements for the foreseeable future, uncertainty exists as to the market price of REO, as evidenced by the volatility experienced in 2022, especially in light of the ~~ongoing~~ COVID-19 pandemic, including the emergence of new and potential future variants. Volatility in the market price of REO has continued ~~into~~in 2023 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.

Our current working capital needs relate mainly to our mining and beneficiation operations. However, as we transition to selling separated ~~REO and other~~ rare earth products, and advance our Stage III magnetics initiatives, we anticipate our working capital needs will ~~increase significantly. Our~~continue to increase. With our Stage II optimization project substantially complete, our principal capital expenditure requirements relate mainly to ~~completing the commissioning of our Stage II optimization project, constructing~~developing the HREE Facility, further investing in Mountain Pass, and ~~developing~~constructing the Fort

T able of Contents

Worth Facility, as well as periodic ~~replacement~~repairs and maintenance of mining orand rare earth processing equipment. Our future capital requirements will also depend on several other factors, including future acquisitions and potential additional investments in further downstream production.

The completion of our mission to become a fully integrated domestic magnetics producer is expected to be capital intensive. In accelerating the strategic opportunity for the separation of HREE, enhancements were made to the initial scope of the Stage II project. Including these enhancements and other factors impacting the remaining cost of completion and including certain early design and procurement costs associated with the HREE Facility, and the development and construction costs of the Fort Worth Facility, as well as other growth and infrastructure investments at Mountain Pass, we expect to spend up to approximately ~~$300~~$270 million of capital costs in 2023. We expect to incur further costs ~~to complete~~for the HREE Facility and the Fort Worth Facility in 2024, in addition to investing in other growth and maintenance projects.

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

Convertible Notes: In March 2021, we issued $690.0 million aggregate principal amount of 0.25% unsecured green convertible senior notes that mature, unless earlier converted, redeemed or repurchased, on April 1, 2026 (the “Convertible Notes”), at a price of par. Interest on the Convertible Notes is payable on April 1st and October 1st of each year, beginning on October 1, 2021.

The Convertible Notes are convertible into shares of our common stock at an initial conversion price of $44.28 per share, or 22.5861 shares, per $1,000 principal amount of notes, subject to adjustment upon the occurrence of certain corporate events. However, in no event will the conversion price exceed 28.5714 shares of common stock per $1,000 principal amount of notes.

We aim to allocate an amount equal to the net proceeds from the Convertible Notes offering to existing or future investments in, or the financing or refinancing of, eligible “green projects.” Eligible green projects are intended to reduce our environmental impact and/or enable the production of low-carbon technologies. Pending such allocation of the net proceeds to eligible green projects, we may use the net proceeds from the Convertible Notes offering for general corporate purposes.

Equipment Notes: We have previously entered into several financing agreements for the purchase of equipment, including trucks, tractors, loaders, graders, and various other machinery. As of ~~March 31,~~September 30, 2023, we had ~~$6.5~~$5.3 million in principal (and accrued interest) outstanding under the equipment notes.

Leases: We have lease arrangements for certain equipment and facilities, including office space, vehicles and equipment used in our operations. As of September 30, 2023, we had future expected lease payment obligations totaling $10.5 million, with $0.9 million due within the next 12 months. See Note 9, “Leases,” in the notes to the unaudited Condensed Consolidated Financial Statements for further information.

Asset Retirement and Environmental Obligations: See Note 7, “Asset Retirement and Environmental Obligations,” in the notes to the unaudited Condensed Consolidated Financial Statements for our estimated cash requirements to settle asset retirement and environmental obligations.

Net Cash Provided by Operating Activities: Net cash provided by operating activities decreased by ~~$65.5~~$237.9 million for the ~~three~~nine months ended ~~March 31,~~September 30, 2023, as compared to the prior year period, reflecting ~~the~~a decrease in ~~product sales and~~revenue, an increase in inventories ~~as we prepare for the operation of~~to support our Stage II separations ~~facilities.~~facilities as well as our Stage III initiatives, and a $6.3 million increase in cash paid for income taxes, as compared to the prior year period. The decrease in net cash provided by operating activities was partially offset by a $19.9 million increase in interest received on our short-term investments and money market funds for the nine months ended September 30, 2023, as ~~a result of excluding~~compared to the prior year period. In addition, $13.6 million of our ~~product sales~~revenue was excluded from cash provided by operating activities for the ~~three~~nine months ended ~~March 31,~~September 30, 2022, since that portion of the sales price was retained by Shenghe to reduce the debt obligation, with no similar amount in the current year period.

Net Cash Provided by (Used in) Investing Activities: Net cash provided by investing activities was ~~$462.2~~$337.8 million for the ~~three~~nine months ended ~~March 31,~~September 30, 2023, compared to net cash used in investing activities of ~~$49.8~~$1,041.7 million in the prior year period. The change related primarily to $705.1 million in higher gross sales and maturities of short-term investments, ~~of $857.5~~coupled with $653.1 million ~~and~~in lower purchases of short-term investments ~~of $320.9 million in~~when compared to the ~~current~~prior year period.

Net Cash Used in Financing Activities: Net cash used in financing activities decreased by ~~$11.1~~$10.9 million for the ~~three~~nine months ended ~~March 31,~~September 30, 2023, as compared to the prior year period, reflecting lower tax withholding on stock-based awards and lower principal payments on debt obligations and finance leases, principally due to a $2.9 million payment to Shenghe in the prior year period to fully satisfy the debt obligation.

Non-GAAP Financial Measures

We present Adjusted EBITDA, Adjusted Net Income, Adjusted Diluted EPS, Production Costs, 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 Income, Adjusted Diluted EPS, Production Costs, and Free Cash Flow are not intended to be ~~a substitute~~substitutes for any GAAP financial ~~measure~~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. As noted above, we no longer utilize Total Value Realized since we do not expect to receive any additional tariff rebates, which we previously adjusted from our ~~product sales~~revenue as determined in accordance with GAAP.

Adjusted EBITDA

We calculate 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; start-up costs; transaction-related and other non-recurring costs; accretion of asset retirement and environmental obligations; gain or loss on ~~sale or disposal~~disposals of long-lived assets; and other income or loss. 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.

These costs include payroll of employees directly involved in 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 develop such 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.

Adjusted Net Income and Adjusted Diluted EPS

We calculate Adjusted Net Income as our GAAP net income or loss excluding the impact of stock-based compensation expense; start-up costs; transaction-related and other non-recurring costs; gain or loss on ~~sale or disposal~~disposals of long-lived assets; 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.~~adjustments; and the release of valuation allowance. We calculate Adjusted Diluted EPS as our GAAP diluted earnings or loss per share (“EPS”) excluding the per share impact, using ~~GAAP~~adjusted diluted weighted-average shares outstanding, ~~as the denominator,~~ of stock-based compensation expense; start-up costs; transaction-related and other non-recurring costs; gain or loss on ~~sale or disposal~~disposals of long-lived assets; 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.~~adjustments; and the release of valuation allowance. Adjusted Net Income 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 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 Income 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 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 provided by operating activities, which is determined in accordance with GAAP:


		For the three months ended March 31,					For the nine months ended September 30,
