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 produces a rare earth concentrate that is principally sold pursuant to the Offtake Agreement to Shenghe (as such terms are defined in Note 14, “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 in the Company’s concentrate and sell the separated products to their customers.

Upon completing commissioning of the Stage II optimization project (“Stage II”), the Company anticipates producing and selling separated rare earth products, including neodymium-praseodymium (“NdPr”) oxide, to customers globally. In February 2023, the Company entered into a distributorship agreement (“Distribution Agreement”) with Sumitomo Corporation of Americas (“Sumitomo”), under which Sumitomo would 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, 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. 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, 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.

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

T able of Contents

(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 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 June 30, 2023, Shenghe was the Company’s principal customer and accounted for more than 90% of product sales. 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, 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 that has previously resulted in tariffs and trade barriers that may negatively affect the Company’s business and results of operations. See Note 14, “Related-Party Transactions,” for additional information.

The impact of the COVID-19 pandemic and its effects continue to evolve. Since 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 not experienced 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 the Company expects a significant increase in inbound logistics of raw materials to be consumed in Stage II operations.

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 is impossible to predict the effect and ultimate impact of the COVID-19 pandemic on the Company’s business, results of operations, production and sales volumes, or growth projects.

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 present value of 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 reduced for payments. The ROU asset also includes other adjustments, such as for the effects of lease prepayments, initial lease costs, or 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. See also Note 7, “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 11, “Stock-based

T able of Contents

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 11, “Stock-based Compensation.”

Recently Issued Accounting Pronouncements: During the three and six months ended June 30, 2023, there were no accounting pronouncements adopted by the Company that had a material impact on the Company’s unaudited Condensed Consolidated Financial Statements. Additionally, as of June 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.

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, 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 June 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.

The Company recognized $0.5 million of gross realized gains and $0.1 million of gross realized losses during the six months ended June 30, 2023. There were no realized gains or losses recognized for the three months ended June 30, 2023 and for the three and six months ended June 30, 2022. Additionally, the Company recognized $13.8 million and $27.1 million of interest and investment income on its available-for-sale securities and other money market funds for the three and six months ended June 30, 2023, respectively, as compared to $1.7 million for the three and six months ended June 30, 2022. These amounts are included in “Other income, net” within the Company’s unaudited Condensed Consolidated Statements of Operations.

Convertible Notes

In March 2021, the Company 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 may, at the Company’s election, be settled in cash, shares of common stock of the Company, or a combination thereof. The Company has the option to redeem the Convertible Notes, in whole or in part, beginning on April 5, 2024.

The Convertible Notes are convertible into shares of the Company’s 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 the Convertible Notes. As of June 30, 2023, based on the conversion price, the maximum number of shares that could be issued to satisfy the conversion feature of the Convertible Notes was 19,714,266.

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, 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.

As of June 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 six months ended June 30, 2023 and 2022.

The balance as of both June 30, 2023, and December 31, 2022, included current portions of $0.2 million. 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 June 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 June 30, 2023, the Company estimated the cash outflows related to these environmental activities will be incurred annually over the next 25 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 six months ended June 30, 2023 and 2022.

The total estimated aggregate undiscounted cost of $26.9 million and $27.2 million as of June 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 June 30, 2023, and December 31, 2022, included current portions of $0.5 million.

T able of Contents

Financial Assurances

The Company is required to provide the applicable government agencies with financial assurances relating to the closure and reclamation obligations. As of June 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 9—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 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 as a percentage of income before income taxes) including discrete items was 42.7% and 23.0% for the three and six months ended June 30, 2023, respectively, as compared to 24.2% and 24.4% for the three and six months ended June 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.

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. The Company does not expect the minimum tax or excise tax to have a material impact on the unaudited Condensed Consolidated Financial Statements. The Company expects 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 of certain critical minerals, including NdPr oxide.

NOTE 10—COMMITMENTS AND CONTINGENCIES

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

NOTE 11—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, 2023, the Company has not issued any stock options or SARs and there were 6,244,076 shares available for future grants under the 2020 Incentive Plan.

Market-Based PSUs: In February 2023, pursuant to the 2020 Incentive Plan, the Company’s Compensation Committee of the Board of Directors adopted a performance share plan (the “2023 Performance Share Plan”). Pursuant to the 2023 Performance Share Plan, for the six months ended June 30, 2023, the Company granted 62,709 of market-based performance stock units (“PSUs”) at target, all of which cliff vest after a requisite performance and service period of three years. The PSUs have the potential to be earned at between 0% and 200% of the number of awards granted depending on the level of growth of the Company’s total shareholder return (“TSR”) as compared to the TSR of the S&P 400 Index and the S&P 400 Materials Group over the performance period. The fair value of the market-based PSUs was determined using a Monte Carlo simulation technique.

NOTE 12—FAIR VALUE MEASUREMENTS

Accounting Standards Codification (“ASC”) Topic 820, “Fair Value Measurements and Disclosures” (“ASC 820”), 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, 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

T able of Contents

inputs are observable in active markets were used to calculate the fair values of liabilities classified within Level 2 of the fair value hierarchy.

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. 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 produce a rare earth concentrate that is principally sold pursuant to the Offtake Agreement to Shenghe (as such terms are defined in Note 14, “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 commissioning of the Stage II optimization project (“Stage II”), we anticipate producing and selling separated rare earth products, including neodymium-praseodymium (“NdPr”) oxide. In addition, we are constructing our initial 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. Furthermore, 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. 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 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.

Tolling Agreement with VREX

In March 2023, we entered into a tolling agreement with Vietnam Rare Earth Company Limited (“VREX”), a majority-owned subsidiary of Shenghe, which owns and operates a metal processing plant and related facilities in Vietnam (the “Tolling Agreement”). Pursuant to the Tolling Agreement, we will deliver NdPr oxide to VREX which VREX will then process into NdPr metal for delivery to our customers globally. As several of our potential customers that manufacture magnets outside of China prefer to purchase NdPr metal in addition to NdPr oxide, this Tolling Agreement will enable us to distribute NdPr products more widely to customers in Japan and other global markets. During the term of the Tolling Agreement, we will pay VREX a processing fee per unit of rare earth metal produced. We will maintain title to the products and directly enter into sales agreements for the produced NdPr metal. The initial term of the Tolling Agreement is three years and may be renewed for additional three-year terms.

COVID-19 Pandemic

The impact of the COVID-19 pandemic and its effects continue to evolve. Since the onset of the pandemic, 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 not experienced 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.

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 currently use the following key performance indicators to evaluate the performance of our business. However, as we evolve as a business and transition 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 to evaluate the business may 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. Our calculations of these performance indicators may differ from similar measures published by other companies in our industry or in other industries. The following table presents our key performance indicators:


	For the three months ended June 30,				Change				For the six months ended June 30,				Change
(in whole units or dollars, except percentages)	2023		2022		Amount		%		2023		2022		Amount		%
REO production volume (MTs)	10,863		10,300		563		5	%	21,534		21,128		406		2	%
REO sales volume (MTs)	10,271		10,000		271		3	%	20,486		21,706		(1,220)		(6)	%
Realized price per REO MT	$	6,231	$	13,918	$	(7,687)	(55)	%	$	7,794	$	13,864	$	(6,070)	(44)	%
Production cost per REO MT	$	1,938	$	1,750	$	188	11	%	$	1,958	$	1,666	$	292	18	%

REO Production Volume

We measure our REO-equivalent production volume for a given period in MTs, our principal unit of sale. This measure refers to the REO content contained in the rare earth concentrate we produce. Our REO production volume is a key indicator of our mining and processing capacity and efficiency. Our REO production volume for the three and six months ended June 30, 2023, included certain concentrate that was stored in bulk silos as mechanically dried and/or roasted concentrate or was fed into downstream circuits as Stage II commissioning activities advanced.

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 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 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 is a key measure of our ability to convert our production into revenue. Our REO sales volume for the three and six months ended June 30, 2023, included both traditional concentrate as well as certain roasted concentrate.

T able of Contents

Realized Price per REO MT

We calculate the realized price per REO MT for a given period as the quotient of: (i) our product sales, which is 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. Historically, we used Total Value Realized, which was a non-GAAP financial measure defined as our product sales adjusted for the revenue impact of tariff rebates related to prior period sales, as the numerator in the calculation of 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 per REO MT.

Production Cost per REO MT

We calculate the 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 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 attributable to certain other sales.

Production 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 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 per REO MT.

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 drivers for REE 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. We 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.

Maximizing Production Efficiency

Since the implementation of our Stage I optimization plan and the achievement of commercial production on July 1, 2019, our quarterly REO production has exceeded 8,500 MTs, and we have produced at least 10,000 MTs of REO production 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, which has allowed us to sustain approximately 95% uptime. Our Stage I optimization 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.

T able of Contents

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 the fourth quarter of 2022 beginning with the concentrate drying and roasting circuits, and continued through the second quarter of 2023, expanding to most of the remaining circuits. Upon reaching run-rate production of REE in Stage II, we expect to be a global low-cost, high-volume producer 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.

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 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 in product sales for the three months ended June 30, 2023, as compared to the prior year period, was driven by lower realized price per REO MT, which decreased by 55%, slightly offset by higher REO sales volume, which increased by 3%. Realized price per REO MT for the three months ended June 30, 2023, reflects a significantly softer pricing environment for rare earth products, as compared to the prior year period. As noted above in the “Factors Affecting our Performance” section, market prices for rare earth products may be volatile due to actual or perceived changes in supply or demand. The higher REO sales volume for the three months ended June 30, 2023, as compared to the prior year period, was due to higher REO production volume, which increased 5% year over year primarily as a result of higher uptime, despite further processing a portion of the volume of REO produced from Stage I operations into the Stage II circuits as commissioning activities advance.

The decrease in product sales for the six months ended June 30, 2023, as compared to the prior year period, was driven by lower realized price per REO MT, which decreased by 44%, and lower REO sales volume, which decreased by 6%. Realized price per REO MT for the six months ended June 30, 2023, reflects the significantly softer pricing environment for rare earth products, as compared to the prior year period when recent pricing peaked. The lower sales volume per REO MT for the six months ended June 30, 2023, as compared to the prior year period, was largely due to the timing of shipments as well as further processing a portion of the volume of REO produced from Stage I operations into the Stage II circuits as commissioning activities advance.

Historically, given our take-or-pay offtake arrangement with Shenghe, our REO sales volume has generally tracked our REO production volumes over time despite period-to-period differences caused by the timing of shipments. However, as we continue to accelerate commissioning activities for Stage II and production of separated rare earth materials, we expect that significant volumes of REO produced from Stage I operations will be retained for separation and not sold as concentrate. Accordingly, we expect that REO sales volume will be significantly lower than REO production volume in the second half of 2023. See also the “Quarterly Performance Trend” section below.

The decrease in other sales for the three and six months ended June 30, 2023, as compared to the prior year periods, was driven by $4.4 million and $8.5 million, respectively, 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 and six months ended June 30, 2023, increased year over year, primarily due to increases in production cost per REO MT. Production cost per REO MT increased from $1,750 for the three months ended June 30, 2022, to $1,938 for the three months ended June 30, 2023, and from $1,666 for the six months ended June 30, 2022, to $1,958 for the six months ended June 30, 2023. The increases were principally driven by higher payroll costs, including the increase in employee headcount to support the expansion of operations, and to a lesser extent, materials and supplies costs, which increased slightly. Shipping and freight costs, which are included in cost of sales but excluded from production cost per REO MT, decreased by $1.5 million and $2.5 million for the three and six months ended June 30, 2023, respectively, as compared to the prior year periods, primarily due to year-over-year declines in trucking rates and diesel fuel prices as well as lower transportation cost per MT of roasted concentrate. Production 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.

Selling, general and administrative expenses for the three months ended June 30, 2023, increased by $0.7 million, or 4%, and decreased by $0.2 million, or less than 1%, for the six months ended June 30, 2023, as compared to the respective prior year periods. Stock-based compensation expense included in selling, general and administrative expenses for the three and six months ended June 30, 2023, decreased by $2.2 million and $5.4 million, 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. These decreases were offset by year-over-year increases in personnel costs (other than stock-based compensation expense), which increased $2.4 million and $4.0 million, respectively, and other general and administrative costs required to further build out our corporate infrastructure in support of our downstream expansion.

Advanced projects, start-up, development and other consists principally of 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 six months ended June 30, 2023, increased year over year primarily due to an increase of $3.3 million and $6.4 million, respectively, in start-up costs, which primarily 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 not yet in commercial

T able of Contents

production. The remaining increase primarily relates 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 six months ended June 30, 2023, primarily reflects an increase in depreciation of $6.9 million and $10.1 million, respectively, resulting from the continued placement of 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 six months ended June 30, 2023, decreased year over year primarily as a result of a 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 of long-lived assets, net consists of gains or losses on the sale or disposal of property, plant and equipment, as well as demolition costs. The year-over-year increase in loss on sale or disposal of long-lived assets, net, for the three and six months ended June 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 capitalized interest. Interest expense, net for the six months ended June 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 six months ended June 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 tax expense as a percentage of income before income taxes) was 42.7% and 23.0% for the three and six months ended June 30, 2023, respectively, as compared to 24.2% and 24.4% for the three and six months ended June 30, 2022, respectively. The effective tax rate for the three and six months ended June 30, 2023, 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 Section 45X Advanced Manufacturing Production Credit and the California Competes Tax Credit (“CCTC”). The effective tax rate for the three and six months ended June 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 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 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 quarters. 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.

The following table presents our key performance indicators for the quarterly periods indicated:


	FY2023				FY2022								FY2021
(in whole units or dollars)	Q2		Q1		Q4		Q3		Q2		Q1		Q4		Q3		Q2
REO production volume (MTs)	10,863		10,671		10,485		10,886		10,300		10,828		10,261		11,998		10,305
REO sales volume (MTs)	10,271		10,215		10,816		10,676		10,000		11,706		9,674		12,814		9,877
Realized price per REO MT	$	6,231	$	9,365	$	8,515	$	11,636	$	13,918	$	13,818	$	10,101	$	7,693	$	7,343
Production cost per REO MT	$	1,938	$	1,978	$	1,928	$	1,653	$	1,750	$	1,594	$	1,525	$	1,449	$	1,538

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 June 30, 2023, we had $1,128.1 million of cash, cash equivalents and short-term investments and $690.0 million principal amount of long-term debt.

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 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.

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 principal capital expenditure requirements relate mainly to completing the commissioning of our Stage II optimization project, constructing the HREE Facility, and developing the Fort Worth Facility, as well as periodic replacement of mining or 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 approximately $300 million of capital costs in 2023. We expect to incur further costs to complete 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 June 30, 2023, we had $5.9 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 June 30, 2023, we had future expected lease payment obligations totaling $10.0 million, with $0.5 million due within the next 12 months. See Note 7, “Leases,” in the notes to the unaudited Condensed Consolidated Financial Statements for further information.

Asset Retirement and Environmental Obligations: See Note 8, “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.

Cash Flows

The following table summarizes our cash flows:


	For the six months ended June 30,				Change
(in thousands, except percentages)	2023		2022		$		%
Net cash provided by (used in):
Operating activities	$	65,459	$	219,862	$	(154,403)	(70)	%

Financing activities	$	(7,599)	$	(18,784)	$	11,185	(60)	%

n.m. - Not meaningful.

Net Cash Provided by Operating Activities: Net cash provided by operating activities decreased by $154.4 million for the six months ended June 30, 2023, as compared to the prior year period, reflecting a decrease in product sales, an increase in inventories as we prepare for the operation of our Stage II separations facilities, and a $6.5 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 an $11.7 million increase in interest received on our short-term investments and money market funds for the six months ended June 30, 2023, as compared to the prior year period. In addition, $13.6 million of our product sales was excluded from cash provided by operating activities for the six months ended June 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 $728.1 million for the six months ended June 30, 2023, compared to net cash used in investing activities of $716.6 million in the prior year period. The change related primarily to gross sales and maturities of short-term investments of $1,179.2 million and purchases of short-term investments of $320.9 million in the current year period, compared to purchases of short-term investments of $599.2 million in the prior year period. Additions to property, plant and equipment for the six months ended June 30, 2023, increased by $7.7 million when compared to the prior year period, relating primarily to continued construction spend on our Stage II optimization project and the Fort Worth Facility.

T able of Contents

Net Cash Used in Financing Activities: Net cash used in financing activities decreased by $11.2 million for the six months ended June 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 for any GAAP financial measure 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 as determined in accordance with GAAP.

Adjusted EBITDA

We calculate Adjusted EBITDA as our GAAP net income 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 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.

The following table presents a reconciliation of our Adjusted EBITDA, which is a non-GAAP financial measure, to our net income, which is determined 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 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 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. We calculate Adjusted Diluted EPS as our GAAP diluted earnings per share (“EPS”) excluding the per share impact, using adjusted diluted weighted-average shares outstanding, of stock-based compensation expense; start-up costs; transaction-related and other non-recurring costs; gain or loss on sale or disposal 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. 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.

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

(1)Tax impact of adjustments is calculated using an adjusted effective tax rate, which excludes the impact of discrete tax costs and benefits, to each adjustment. The adjusted effective tax rates were 31.3%, 25.1%, 24.0% and 24.7% for the three and six months ended June 30, 2023 and 2022, respectively.

(2)Effective September 30, 2022, we no longer exclude depletion expense when calculating and presenting Adjusted Diluted EPS. For purposes of comparability, we have revised the prior year for this change.

(3)The Convertible Notes were antidilutive for GAAP purposes for the three months ended June 30, 2023. For purposes of calculating Adjusted Diluted EPS, we have added back the assumed conversion of the Convertible Notes since they would not be antidilutive when using Adjusted Net Income as the numerator in the calculation of Adjusted Diluted EPS.

Production Costs

Production Costs, which we use to calculate our key performance indicator, production cost per REO MT, is a non-GAAP financial measure. Production cost per REO MT is a key indicator of our concentrate production efficiency. As mentioned above, in completing the transition to separated rare earth products, we may determine that production cost per REO MT, which is a metric focused solely on Stage I concentrate operations, and consequently, Production Costs, are no longer meaningful in evaluating and understanding our business or operating results.

The following table presents a reconciliation of our Production Costs to our cost of sales (excluding depreciation, depletion and amortization), which is determined in accordance with GAAP, as well as the calculation of production cost per REO MT:


	For the three months ended June 30,				For the six months ended June 30,
(in thousands, unless otherwise stated)	2023		2022		2023		2022
Cost of sales (excluding depreciation, depletion and amortization)	$	22,704	$	22,092	$	46,920	$	45,265
Adjusted for:
Stock-based compensation expense(1)	(795)		(506)		(1,917)		(1,221)
Shipping and freight	(1,995)		(3,508)		(4,283)		(6,752)
Other	(11)		(580)		(614)		(1,136)
Production Costs	19,903		17,498		40,106		36,156
Divided by:
REO sales volume (in MTs)	10,271		10,000		20,486		21,706
Production cost per REO MT (in dollars)	$	1,938	$	1,750	$	1,958	$	1,666

(1)Pertains only to the amount of stock-based compensation expense included in cost of sales.

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 six months ended June 30,
(in thousands)	2023		2022
Net cash provided by operating activities(1)	$	65,459	$	219,862
Additions to property, plant and equipment, net(2)	(130,236)		(117,454)
Free Cash Flow	$	(64,777)	$	102,408

(1)Under the terms of the A&R Offtake Agreement and pursuant to the accounting treatment thereof, $13.6 million of our product sales for the six months ended June 30, 2022, were excluded from cash provided by operating activities since that portion of the sales price was retained by Shenghe to reduce the debt obligation.

(2)Amounts for the six months ended June 30, 2023 and 2022, are net of zero and $5.1 million, respectively, in proceeds from government awards used for construction, specifically our Stage II optimization project.
