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. ~~We own~~The Company, which is headquartered in Las Vegas, Nevada, owns and ~~operate~~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. ~~The Company is headquartered in Las Vegas, Nevada. References herein to the “Company,” “we,” “our,” and “us,” refer to~~ MP Materials ~~Corp. and its subsidiaries.~~

We currently ~~produce~~produces a rare earth concentrate that ~~we sell~~is principally sold pursuant to ~~an offtake agreement~~the Offtake Agreement to Shenghe ~~Resources (Singapore) International Trading Pte. Ltd. (“Shenghe”~~(as such terms are defined in Note 14, “Related-Party Transactions,”), a majority-owned subsidiary of Leshan Shenghe 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. We are currently recommissioning, upgrading and enhancing the processing facility at Mountain Pass to provide for the separationrelated party of the ~~individual~~Company, that, in turn, typically sells that product to refiners in China. These refiners separate the constituent rare earth elements contained in ~~our~~the Company’s concentrate ~~(referred~~and sell the separated products to astheir customers.

Upon completing commissioning of the ~~“Stage~~Stage II optimization ~~project” or “Stage~~project (“Stage II”), ~~that will allow us to sell~~the Company anticipates producing and selling separated rare earth ~~oxides directly~~products, including neodymium-praseodymium (“NdPr”) oxide, to ~~end users. Additionally,~~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 ~~first quarter~~Distribution Agreement, the Company and Sumitomo intend to collaborate on the supply of ~~2022, we began construction on our~~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”) ~~as a part of our Stage III downstream expansion strategy~~, where it anticipates manufacturing, among other products, neodymium-iron-boron (“~~Stage III”~~NdFeB”)~~. For more information on our relationship and agreements with Shenghe, see~~ ~~Note 3, “Relationship and Agreements with Shenghe,”~~ ~~and~~ ~~Note 14, “Related-Party Transactions.”~~

In permanent magnets. Furthermore, in April 2022, the Company entered into a ~~definitive~~ 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. ~~The definitive long-term supply agreement solidifies~~These developments are a part of the ~~terms of a binding agreement announced by the Company in December 2021.~~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 ~~chief operating decision maker~~CODM views the Company’s operations and manages the business as 1one 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, ~~2021.~~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.

T ~~able of Contents~~

Concentration of Risk: Financial instruments that potentially subject the Company to credit risk consist principally of cash, ~~and~~ 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 ~~with~~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, ~~2022,~~2023, Shenghe ~~a related party of~~was the ~~Company and our~~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.~~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 ~~3, “Relationship and Agreements with Shenghe,~~14, “Related-Party Transactions,” for additional information.

~~In December 2019, a novel strain~~The impact of coronavirus (known as “COVID-19”) began to impact the population of China. In March 2020, the outbreak of COVID-19 was declared a global pandemic after growing both in the United States and globally. The responses by governments, societies, and private sector entities to the COVID-19 pandemic ~~which include temporary closures of businesses, social distancing, travel restrictions, “shelter in place,”~~ and other governmental regulations and various economic stimulus programs, have significantly impacted market volatility and general global economic conditions, including significant business and supply chain disruption as well as broad-based changes in supply and demand.

its effects continue to evolve. Since the onset of the ~~COVID-19~~ pandemic, ~~we have~~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. ~~Congestion and slowdowns have affected and may continue to affect the capacity at ports to receive deliveries of products or the loading of shipments onto vessels.~~ Despite these factors, ~~we have~~the Company has not experienced a reduction in production or sales due to the COVID-19 ~~pandemic; however,~~pandemic. However, the COVID-19 pandemic has contributed to certain cost and schedule pressures onfor 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 ~~optimization project.~~ operations.

The Company has worked proactively and diligently to adjust working schedules and hours to optimize logistics and shipping, which has thus far prevented a significant negative impact on our product sales and has mitigated certain impacts on Stage II construction and recommissioning progress. However, there can be no assurance that the ongoing COVID-19 pandemic will not have a negative impact on our production, sales, or growth projects in the future.

~~As the situation~~ continues to ~~evolve,~~monitor the global situation, including ~~as a result~~the impacts of new and potential future variants of COVID-19, ~~the possibility of federal or state mandates on vaccinations,~~ or other factors that may affect international shipping, logistics, and ~~logistics~~supply chain, or involve responses to government actions such as strikes or other ~~disruptions, it~~disruptions. It is impossible to predict the effect and ultimate impact of the COVID-19 pandemic on the Company’s business, ~~and~~ results of ~~operations. The extent~~operations, production and ~~duration of any business disruptions, and related financial impact, cannot be estimated at this time.~~sales volumes, or growth projects.

~~Cash, Cash Equivalents~~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 ~~Short-term Investments:~~ ~~Cash~~non-lease components. The Company has elected to use a practical expedient to account for each separate lease component and ~~cash equivalents consist~~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 ~~cash balances and highly liquid investments, including U.S. treasury and agency securities,~~leases with a ~~maturity~~lease term greater than 12 months. The Company has elected to use a practical expedient to not recognize leases with a lease term of ~~three~~12 months or less ~~at the time of purchase.~~

The Company’s short-term investments consist of U.S. treasury and agency securities that have original maturities greater than three months at the time of purchase. These investments have been classified and accounted for as available-for-sale securities and the Company reevaluates the classification each reporting period. The Company classifies its available-for-sale securities as either current or non-current based on each instrument’s underlying contractual maturity date and the Company’s expectations of sales and redemptions within the next twelve months. See ~~Note 4, “Cash, Cash Equivalents and Investments,”~~ ~~for additional information.~~

~~Available-for-sale securities are recorded at fair value each reporting period. For unrealized losses~~ in securities that the Company intends to hold and will not more likely than not be required to sell before recovery, the Company further evaluates whether declines in fair value below amortized cost are due to credit or non-credit related factors. The Company considers credit related impairments to be changes in value that are driven by a change in the creditor’s ability to meet its payment obligations, and records an allowance and recognizes a corresponding loss when the impairment is incurred.

~~Unrealized non-credit related losses and unrealized gains are reported, net of income taxes, in accumulated other comprehensive income or loss, a component of stockholders’ equity within~~ the unaudited Condensed Consolidated Balance Sheets ~~until realized. Realized gains~~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 ~~losses~~lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and lease liabilities are ~~reported within our unaudited Condensed Consolidated Statements~~recognized at commencement date of ~~Operations upon realization. Accrued~~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 ~~receivable is~~based on the interest method using the discount rate determined at lease commencement. For operating and finance leases, variable lease payments not included in ~~“Accounts receivable (including related party)” within~~ the ~~Company’s unaudited Condensed Consolidated Balance Sheets.~~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: ~~There were no new accounting pronouncements recently issued or effective during~~During the three and six months ended June 30, ~~2022,~~2023, there were no accounting pronouncements adopted by the Company that had ~~or would be~~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~~Company's unaudited Condensed Consolidated Financial Statements.

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

NOTE 3—~~RELATIONSHIP AND AGREEMENTS WITH SHENGHE~~

~~Offtake Agreement~~

In March 2022, the Company entered into an offtake agreement with Shenghe (the “Offtake Agreement”), which became effective upon the termination of the A&R Offtake Agreement (as discussed and defined below). 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 shall 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.

Similar to the A&R Offtake Agreement, 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.

~~Original Commercial Agreements~~

In May 2017, the Company entered into a set of commercial arrangements with Shenghe, which included a technical services agreement (the “TSA”) and an offtake agreement (the “Original Offtake Agreement”). The Original Offtake Agreement required Shenghe to advance the Company an initial $50.0 million (the “Initial Prepayment Amount”) to fund the restart of operations at the mine and the TSA required Shenghe to fund any additional operating and capital expenditures required to bring Mountain Pass to full operability. Shenghe also agreed to provide additional funding of $30.0 million to the Company pursuant to a separate letter agreement dated June 20, 2017 (the “Letter Agreement”) (the “First Additional Advance”), in connection with our acquisition of Mountain Pass. In addition to the repayment of the First Additional Advance, pursuant to the Letter Agreement, the Initial Prepayment Amount increased by $30.0 million. We refer to the aggregate prepayments made by Shenghe pursuant to the Original Offtake Agreement and the Framework Agreement (defined below), as adjusted for Gross Profit Recoupment (defined below) amounts and any other qualifying repayments to Shenghe, inclusive of the $30.0 million increase to the Initial Prepayment Amount, as the “Prepaid Balance.”

Under the Original Offtake Agreement, we sold to Shenghe, and Shenghe purchased on a firm “take or pay” basis, all of the rare earth products produced at Mountain Pass. Shenghe marketed and sold these products to customers, and retained the gross profits earned on subsequent sales. The gross profits were credited against the Prepaid Balance, and provided the means by which we repaid, and Shenghe recovered, such amounts (the “Gross Profit Recoupment”).

~~Framework Agreement and Restructured Commercial Agreements~~

In May 2020, the Company entered into a framework agreement and amendment (the “Framework Agreement”) with Shenghe and Leshan Shenghe that restructured the commercial arrangements and provided for, among other things, a revised funding amount and schedule to settle Shenghe’s prepayment obligations to the Company, as well as an amendment to the Original Offtake Agreement, as discussed below.

Pursuant to the Framework Agreement, the Company entered into an amended and restated offtake agreement with Shenghe on May 19, 2020 (the “A&R Offtake Agreement”), which, upon effectiveness, superseded and replaced the Original Offtake Agreement. Pursuant to the Framework Agreement, Shenghe funded the remaining portion of the Initial Prepayment Amount and agreed to fund an additional $35.5 million advance (the “Second Additional Advance” and together with the Initial Prepayment Amount, inclusive of the $30.0 million increase pursuant to the Letter Agreement, the “Offtake Advances”), which amounts were fully funded in June 2020.

T ~~able of Contents~~

The A&R Offtake Agreement maintained the key take-or-pay, amounts owed on actual and deemed advances from Shenghe, and other terms of the Original Offtake Agreement, with the following changes, among other items: (i) as to the offtake products subject to the A&R Offtake Agreement, provided that if we sold such offtake products to a third party, then, until the Prepaid Balance was reduced to zero, we would pay an agreed percentage of our revenue from such sales to Shenghe, to be credited against the amounts owed on Offtake Advances; (ii) provided that the sales price to be paid by Shenghe for our rare earth products (a portion of which reduces the Prepaid Balance rather than being paid in cash) would be based on market prices (net of taxes, tariffs and certain other agreed charges) less applicable discounts; and (iii) obliged us to pay Shenghe, on an annual basis, an amount equal to our annual net income, less any amounts recouped through the Gross Profit Recoupment mechanism over the course of the year, until the Prepaid Balance was reduced to zero.

The sales price and other terms applicable to a quantity of offtake products were set forth in monthly purchase agreements between the Company and Shenghe. In March 2022, the Company made a $2.9 million payment to Shenghe pursuant to item (iii) discussed above. Upon payment by the Company, the Prepaid Balance was repaid in full, and the A&R Offtake Agreement was terminated.

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 ~~notes.~~the Convertible Notes. As of June 30, ~~2022,~~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.

~~Offtake Advances~~

Under the A&R Offtake Agreement, a portion of the sales prices of products sold to Shenghe was paid in the form of debt reduction, rather than cash. In addition, the Company had to pay the following amounts to Shenghe in cash to reduce the debt obligation until repaid in full: (i) an agreed-upon percentage of sales of products to parties other than Shenghe under the A&R Offtake Agreement; (ii) 100% of net profits from asset sales; and (iii) 100% of net income determined under GAAP, less the tax-effected amount of total non-cash recoupment from sales of products to Shenghe. For the three and six months ended June 30, 2022, zero and $14.2 million, respectively, of the sales prices of products sold to Shenghe was paid in the form of debt2023.

T able of Contents

~~reduction (see~~ ~~Note 15, “Supplemental Cash Flow Information”~~), as compared to $11.7 million and $20.9 million, for the three and six months ended June 30, 2021, respectively. During the three and six months ended June 30, 2022, the Company made payments to Shenghe of zero and $0.2 million, respectively, based on sales to other parties, as compared to $0.1 million for the three and six months ended June 30, 2021. No amounts were required to be paid based on asset sales.

The A&R Offtake Agreement did not have a stated rate (and was non-interest-bearing), and repayment was contingent on a number of factors, including market prices realized by Shenghe, the Company’s sales to other parties, asset sales, and the Company’s annual net income. The imputed interest rate was a function of this discount taken together with our expectations about the timing of the anticipated reductions of the principal balance. The Company had determined that it would recognize adjustments from these estimates following a prospective method where the Company updated its estimate of the effective interest rate in future periods based on revised estimates of the timing of remaining principal reductions at that time. The effective rate applicable from the June 5, 2020, inception to full repayment, was between 4.41% and 24.75%.

~~As discussed in~~ ~~Note 3, “Relationship and Agreements with Shenghe,”~~ ~~the Company made a $2.9 million payment to Shenghe in March 2022. Upon payment by the Company, the Prepaid Balance was repaid in full, and the A&R Offtake Agreement was terminated.~~

~~Paycheck Protection Loan~~

In April 2020, the Company obtained a loan of $3.4 million pursuant to the Paycheck Protection Program under the CARES Act, (the “Paycheck Protection Loan”). In June 2021, the Company received notification from the Small Business Administration that the Paycheck Protection Loan and related accrued interest was forgiven. Consequently, during the three and six months ended June 30, 2021, the Company recorded a gain on forgiveness of the Paycheck Protection Loan in the amount of $3.4 million, which is included in “Other income” within our unaudited Condensed Consolidated Statements of Operations.

~~Tariff-Related Rebates~~

In May 2020, the government of the People’s Republic of China suspended certain tariffs that had been charged to consignees of our product on imports, and provided such relief retroactive to March 2020. In addition, Shenghe began negotiating for tariff rebates from sales prior to March 2020, which affected Shenghe’s realized prices, and thus the Prepaid Balance. These, in turn, affected the Company’s realized prices on prior sales. While additional tariff rebates were possible, the Company did not have insight into Shenghe’s negotiations or their probability of success, and such negotiations were outside of the Company’s control. Thus, the Company fully constrained estimates of any future tariff rebates that may have been realized at that time.

In January 2021, the Company received information from Shenghe regarding its successful negotiation of additional tariff rebates. Consequently, the Company revised its estimates of variable consideration and recognized $2.0 million of revenue for the six months ended June 30, 2021. Additionally, for the six months ended June 30, 2021, the Company recorded a reduction in the principal balance of the debt obligation and the corresponding debt discount of $2.2 million and $0.2 million, respectively.

Equipment Notes

The Company has entered into several financing agreements for the purchase of equipment, including trucks, tractors, loaders, graders, and various other machinery. The Company’s equipment notes, which are secured by the purchased equipment, have terms of between 4 to 5 years and interest rates of between 0.0% and 6.5% per annum.

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

NOTE 7—LEASES

The Company has operating and finance leases for certain office space, warehouses, vehicles and equipment used in its operations. In November 2021, the Company entered into a lease agreement for corporate office space. The lease commenced during the second quarter of 2023, and at lease commencement, the Company recorded an operating lease liability of $7.3 million and an ROU asset of $10.3 million, primarily comprised of the lease liability as well as $2.9 million of payments for lessor-owned tenant improvements.

NOTE 8—ASSET RETIREMENT AND ENVIRONMENTAL OBLIGATIONS

Asset Retirement Obligations

The Company estimates asset retirement obligations based on the requirements to reclaim ~~its mine pit~~certain land areas associated with mineral extraction activities and certain related ~~processing and separations~~ facilities at Mountain Pass. Minor reclamation activities related to discrete portions of the Company’s operations are ongoing. As of June 30, ~~2022,~~2023, the Company estimated a significant portion of the cash outflows for ~~the~~ major reclamation ~~and~~activities including the retirement of Mountain Pass will be incurred beginning in ~~2057.~~

In June 2021, San Bernardino County approved the Company’s re-zoning request for certain of its properties such that certain of the Company’s processing facilities would be zoned for industrial end uses as opposed to the prior “resource conservation” designation, which may obviate the Company’s current requirement to demolish2056 and reclaim the impacted areas. In March 2022, based on the Company’s preliminary evaluation of the impact of the re-zoning, the Company submitted a revised reclamation plan to San Bernardino County for review. After acceptance of the reclamation plan by San Bernardino County and final approval by the State of California, which have not yet occurred as of June 30, 2022, the Company will update the estimated cash flows underlying its asset retirement obligations, as the Company’s existing reclamation obligations will not be legally reduced until such approval is obtained.2057.

As of June 30, ~~2022,~~2023, the credit-adjusted risk-free rate ranged between 6.5% and ~~8.2%~~12.0% depending on the timing of expected settlement and when the ~~layer or~~ increment was recognized. There were no significant increments or decrements for the three and six months ended June 30, ~~2022~~2023 and ~~2021.~~2022.

The balance as of both June 30, ~~2022,~~2023, and December 31, ~~2021,~~2022, included current portions of ~~$0.1~~$0.2 million. The total estimated future undiscounted cash flows required to satisfy the Company’s asset retirement obligations were ~~$167.2~~$50.3 million and ~~$167.3~~$50.4 million as of June 30, ~~2022,~~2023, and December 31, ~~2021,~~2022, respectively.

The Company is required to provide the applicable government agencies with financial assurances relating to the closure and reclamation obligations. As of June 30, 2022, and December 31, 2021, the Company had financial assurance requirements of $42.3 million and $39.0 million, respectively, which were satisfied with surety bonds placed with the California state and regional agencies.

Environmental Obligations

The Company ~~assumed~~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, ~~management~~the Company developed an estimate of future cash payments for the remediation plan.

As of June 30, ~~2022, management~~2023, the Company estimated the cash outflows related to these environmental activities will be incurred annually over the next 2625 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, ~~2022~~2023 and ~~2021.~~2022.

The total estimated aggregate undiscounted cost of ~~$27.4~~$26.9 million and ~~$27.7~~$27.2 million as of June 30, ~~2022,~~2023, and December 31, ~~2021,~~2022, respectively, ~~was~~ principally related to water monitoring ~~and treatment~~ activities required by state and local agencies. Based on ~~management’s best~~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, ~~2022,~~2023, and December 31, ~~2021,~~2022, included current portions of $0.5 million.

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 ~~taxes~~tax expense as a percentage of income ~~or loss~~ 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, as compared to 18.5% and 19.8% for the three and six months ended June 30, 2021,~~ respectively. ~~Our~~The Company’s effective income tax rate can vary from period to period depending on, among other factors, percentage depletion, executive compensation deduction limitations, ~~other permanent book/tax items,~~the Section 45X Advanced Manufacturing Production Credit, and changes to ~~our~~its valuation

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.

NOTE 12—FAIR VALUE MEASUREMENTS

~~ASC~~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.

T ~~able of Contents~~

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.

~~Offtake Advances~~

The Company’s Offtake Advances were classified within Level 3 of the fair value hierarchy as of December 31, 2021, because there were unobservable inputs that followed an imputed interest rate model to calculate the amortization of the embedded debt discount, which was recognized as non-cash interest expense, by estimating the timing of anticipated payments and reductions of the debt principal balance. This model-based valuation technique, for which there were unobservable inputs, was used to estimate the fair value of the liability classified within Level 3 of the fair value hierarchy as of December 31, 2021.

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.

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:

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, ~~2021.~~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. ~~In addition, see~~See also “Cautionary Note Regarding Forward-Looking Statements.”

Business Overview

~~References herein to the “Company,” “we,~~MP Materials Corp., including its subsidiaries (“we,” “our,” and ~~“us,” refer to MP Materials Corp. and its subsidiaries.~~

~~Overview~~

~~MP Materials Corp.~~“us”), is the largest producer of rare earth materials in the Western Hemisphere. ~~The Company owns~~We own and ~~operates~~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 ~~estimate the rare earth concentrate we produced and sold in 2021 represented approximately 15% of the rare earth content consumed in the global market.~~

Rare earth elements (“REE”) are fundamental building blocks of the modern economy, impacting trillions of dollars in global economic activity through the enablement of end products across industries including transportation, clean energy, robotics, national defense and consumer electronics, among others. Neodymium (“Nd”) and praseodymium (“Pr”) are rare earth elements which in combination form neodymium-praseodymium (“NdPr”), which represents a majority of the value contained in our rare earth concentrate. NdPr is most often utilized in NdPr magnets, which are also commonly referred to as “neo,” “NdFeB,” “NIB,” or permanent magnets and are made predominantly from an alloy of NdPr, iron and boron. NdPr magnets are the most widely used type of rare earth magnets and are critical for many advanced technologies that are experiencing strong secular growth, including electric vehicles (“EV”), drones, defense systems, wind turbines, robotics and many others. The rapid growth of these and other advanced motion technologies is expected to drive substantial demand growth for NdPr.

We produce our materials at Mountain Pass, one of the world’s richest rare earth deposits, co-located with integrated state-of-the-art processing and separation facilities. We acquired the Mountain Pass assets in 2017, restarted operations from cold-idle status and embarked on a deliberate, two-stage plan to optimize the facility and position the Company for growth and profitability. We commenced mining, comminution, beneficiation, and tailings management operations, which we designated Stage I of our multi-stage optimization plan, between December 2017 and February 2018.

We currently produce a rare earth concentrate that ~~we sell~~is principally sold pursuant to the Offtake Agreement to Shenghe ~~Resources (Singapore) International Trading Pte. Ltd. (“Shenghe”)~~(as such terms are defined in Note 14, “Related-Party Transactions,” in the notes to the unaudited Condensed Consolidated Financial Statements), ~~an affiliate of Shenghe Resources Holding Co., Ltd., which,~~that, in turn, typically sells that product to refiners in China. These refiners separate the constituent ~~REE~~rare earth elements (“REE”) contained in our concentrate and sell the separated products to their customers.

Upon ~~completion~~completing commissioning of ~~our~~the Stage II optimization project (“Stage II”), we anticipate producing and selling separated rare earth ~~oxides~~products, including neodymium-praseodymium (“~~REO”~~NdPr”)~~, including NdPr oxide, and selling these products directly to end users, at which time~~ oxide. In addition, we ~~may no longer sell our concentrate.~~

~~In February 2022, we commenced construction of~~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 ~~definitive~~ 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. ~~The definitive long-term supply agreement solidifies the terms of a binding agreement announced by the Company in December 2021.~~ 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					For the three months ended June 30,				Change				For the six months ended June 30,				Change

REO Production Volume

We measure our REO-equivalent production volume for a given period in ~~metric tons (“MTs”),~~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 ~~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. ~~As noted above, upon completion of Stage II, we expect to refine our rare earth concentrate to produce separated rare earths, including NdPr oxide.~~

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.~~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.

Realized Price per REO MT

We calculate the realized price per REO MT for a given period as the quotient of: (i) our ~~Total Value Realized (see below)~~product sales, which is determined in accordance with GAAP, for a given period and (ii) our REO sales volume for the same period. ~~We define~~Realized price per REO MT is an important measure of the market price of our concentrate product. Historically, we used Total Value Realized, which iswas a non-GAAP financial measure defined as our product sales adjusted for the revenue impact of tariff rebates related to prior period ~~sales.~~

~~Realized price per REO MT is an important measure of~~sales, as the ~~market price of our product. Accordingly, we calculate realized price per REO MT to reflect a consistent basis between periods by eliminating the revenue impact of tariff-related rebates. See the~~ ~~“Non-GAAP Financial Measures”~~ ~~section below for a reconciliation of our Total Value Realized, which is a non-GAAP financial measure, to our product sales, which is determined~~numerator in ~~accordance with generally accepted accounting principles in the United States (“GAAP”), as well as~~ 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, for a given period.~~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.

~~Key~~ 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:~~including clean-energy and transportation technologies, ~~(e.g., traction motors in EVs~~consumer and ~~generators in wind power turbines); high-technology~~medical applications, ~~(e.g., miniaturization of smart phones and other mobile devices, fiber optics, lasers, robotics, medical devices, etc.);~~ critical defense ~~applications (e.g., guidance and control~~ systems, ~~global positioning systems, radar and sonar, drones, etc.);~~ and essential industrial ~~infrastructure (e.g., advanced catalyst applications in oil refining and pollution-control systems in traditional internal-combustion automobiles, etc.).~~infrastructure. We believe ~~these drivers will fuel~~we benefit from the continued growth of the rare earth market, particularly the market for NdPr and permanent ~~magnets.~~

~~We believe we benefit~~magnets, and from several demand tailwinds for ~~REE, and particularly for NdPr.~~REE. These include the trend toward electrification; geographic supply chain diversification, particularly in relation to ~~China,~~China; the U.S. government ~~strategy~~initiatives to restore domestic supply of key ~~minerals,~~minerals; and the increasing acceptance of environmental, social and governance mandates.

However, changes in technology ~~may~~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

~~In 2021, REO production was approximately 3.5x greater than~~Since the ~~highest ever production in a twelve-month period by the prior operator~~implementation of Mountain Pass using principally the same capital equipment. We achieved these results through an optimized reagent scheme, lower process temperatures, better management of the tailings facility, and a commitment to operational excellence, driving approximately 95% uptime. We also believe that our Stage I optimization ~~initiatives~~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 ~~unit~~MT of REO produced in concentrate. Furthermore, we designed our Stage II ~~is designed to enable us to continue to manage our cost structure for separating REE through an optimized facility~~ process ~~flow. The reintroduction of the oxidizing roasting step will allow us~~flow to capitalize on the inherent advantages of the bastnaesite ore at Mountain Pass, ~~which~~that is ~~uniquely suitable~~well-suited to low-cost refining by selectively eliminating the need to carry cerium, a lower-value ~~cerium~~mineral, through the separations process. ~~The recommissioning of our natural gas-powered combined heat and power (“CHP”) plant, which was completed in December 2021, removed our reliance on the regional electric power grid. Further,~~Additionally, our location offers ~~significant~~ 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 ~~greater~~more capital, which may allow them to make similar or greater efficiency improvements or undercut market prices for our product.

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 ~~completion~~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.

~~Further,~~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 ~~pursuing vertical integration opportunities~~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, ~~and~~while incorporating magnet recycling ~~capability.

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.

In February 2022, we were awarded a $35.0 million contract by the Department of Defense’s Office of Industrial Base Analysis and Sustainment Program to design and build a facility to process heavy rare earth elements (“HREE”). Successful completion of this project will establish the first processing and separation facility of its kind for HREEs in support of commercial and defense applications in the United States. The HREE processing and separations facility will be built at Mountain Pass and tie into our other Stage II facilities.

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 ~~September 30, 2021,~~December 31, 2022, SRK Consulting (U.S.), Inc., an independent consulting firm that we retained to assess our reserves, ~~estimates~~estimated total proven and probable reserves of ~~2.1~~1.96 million short tons of REO contained in ~~30.4~~29.30 million short tons of ore at Mountain Pass, with an average ore grade of ~~6.36%~~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 ~~completion~~completing the commissioning of Stage II, ~~as of September 30, 2021,~~ our expected mine life was approximately ~~35 years. We~~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 ~~programs over time.~~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.

~~Recent Developments~~

~~Offtake Agreement with Shenghe~~

In March 2022, the Company entered into an offtake agreement with Shenghe (the “Offtake Agreement”), which became effective upon the termination of the A&R Offtake Agreement (as discussed and defined in ~~Note 3, “Relationship and Agreements with Shenghe,”~~ in the notes to the unaudited Condensed Consolidated Financial Statements). 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. See the ~~“Liquidity and Capital Resources”~~ ~~section below for additional information on the termination of the A&R Offtake Agreement.~~

The sales price of rare earth concentrate sold to Shenghe 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. 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.

~~Impact of the COVID-19 Pandemic~~

In December 2019, a novel strain of coronavirus (known as “COVID-19”) began to impact the population of China. In March 2020, the outbreak of COVID-19 was declared a global pandemic after growing both in the United States and globally. The responses by governments, societies, and private sector entities to the COVID-19 pandemic, which include temporary closures of businesses, social distancing, travel restrictions, “shelter in place,” and other governmental regulations and various economic stimulus programs, have significantly impacted market volatility and general global economic conditions, including significant business and supply chain disruption as well as broad-based changes in supply and demand.

Since the onset of the COVID-19 pandemic in the first quarter of 2020, 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. Congestion and slowdowns have affected and may continue to affect the capacity at ports to receive deliveries of products or the loading of shipments onto vessels. 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 on the Stage II optimization project. The Company has worked proactively and diligently to adjust working schedules and hours to optimize logistics and shipping, which has thus far prevented a significant negative impact on our product sales and has mitigated certain impacts on Stage II construction and recommissioning progress. However, there can be no assurance that the ongoing COVID-19 pandemic will not have a negative impact on our production, sales, or growth projects in the future.

Furthermore, as the situation continues to evolve, including as a result of new and potential future variants of COVID-19, the possibility of federal or state mandates on vaccinations, or other factors that may affect international shipping and logistics 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 and results of operations. The extent and duration of any business disruptions, and related financial impact, cannot be estimated at this time.

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.

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 ~~increase~~decrease in other sales for the three and six months ended June 30, ~~2022,~~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 (“REF”).~~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.

These increases in costs offset production efficiencies achieved during the three months ended June 30, 2022.~~

~~Cost of sales for the six months ended June 30, 2022, increased year over year~~periods, primarily due to ~~higher REO sales volume. The increase~~year-over-year declines in ~~production cost per REO MT from $1,507 for the six months ended June 30, 2021, to $1,666 for the six months ended June 30, 2022, is due to higher materials, supplies~~trucking rates and ~~payroll costs, including an increase in employee headcount to support the expansion of operations,~~diesel fuel prices as well as higher energy costs incurred following the restart of our CHP plant in January 2022.

These increases in costs offset production efficiencies achieved during the six months ended June 30, 2022.

~~Notwithstanding the increase in employee headcount discussed above and the impact of costs associated with recommissioning the CHP plant, we believe our production~~lower transportation cost per ~~REO~~ MT ~~has stabilized in the short-term, with operating efficiencies helping to offset the impact~~ of inflationary pressure on materials, supplies, energy and labor.

Advanced projects, development and other for the three and six months ended June 30, 2022, increased year over year primarily due to certain start-up costs that do not qualify for capitalization associated with our Stage II optimization project and our Stage III initiatives. In addition, the year-over-year increase for the six months ended June 30, 2022, includes one-time start-up costs associated with restart of our CHP plant.

Interest and investment income for the three and six months ended June 30, 2022,2023, 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 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, as compared to 18.5% and 19.8%~~respectively. The effective tax rate for the three and six months ended June 30, ~~2021. The effective tax rates~~2023, differed from the statutory tax rate of 21% primarily due to state income tax expense and a deduction limitation on ~~officer’s~~officers’ compensation, offset by the Section 45X Advanced Manufacturing Production Credit and the California Competes Tax Credit (“CCTC”).

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. 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:

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, ~~2022,~~2023, we had ~~$1,264.1~~$1,128.1 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 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, as well as our Stage II optimization project and related HREE project and the development of the Fort Worth Facility.~~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 ~~design and~~initial scope of the ~~initial~~ 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 ~~initial costs of a~~ HREE ~~separation facility~~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 ~~incur up to~~spend approximately ~~$500~~$300 million of capital costs in ~~2022.~~2023. We expect to incur further costs ~~in 2023 and 2024~~ to complete the HREE ~~separation facility~~Facility and the Fort Worth ~~Facility.~~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.

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 ~~the Company’s~~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 ~~the Company’s~~our environmental impact and/or enable the production of low-carbon technologies. Pending such allocation of the net proceeds to eligible green projects, we ~~intend to~~may use the net proceeds from the Convertible Notes offering for general corporate purposes.

~~Offtake Advances:~~ In March 2022, the Company made a $2.9 million payment to Shenghe pursuant to an obligation under the A&R Offtake Agreement to pay Shenghe, on an annual basis, an amount equal to our annual net income, less any amounts recouped through the Gross Profit Recoupment mechanism over the course of the year, until the Prepaid Balance was reduced to zero (terms as discussed and defined in ~~Note 3, “Relationship and Agreements with Shenghe,”~~ ~~in the notes to the unaudited Condensed Consolidated Financial Statements).~~

Upon payment by the Company, the Prepaid Balance was repaid in full, and the A&R Offtake Agreement was terminated. Prior to full repayment, the debt to Shenghe was satisfied primarily through product sales, where partial non-cash consideration was received by the Company in the form of debt reduction (generally equal to approximately 15% of the ultimate market value of the REO, excluding tariffs, duties and certain other charges).

As of June 30, ~~2022,~~2023, we had ~~$8.4~~$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.

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, ~~compared to $22.9 million~~with no similar amount in the ~~prior~~current year period.

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 ~~Total Value Realized, Production Costs,~~ 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. ~~Total Value Realized, Production Costs,~~ 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.

~~Total Value Realized~~

As noted above, we no longer utilize Total Value Realized since we do not expect to receive any additional tariff rebates, which we use to calculate our key performance indicator, realized price per REO MT, is a non-GAAP financial measure. As mentioned above, realized price per REO MT is an important measure of the market price of our product. The following table presents a reconciliation of our Total Value Realized, topreviously adjusted from our product sales ~~which is~~as determined in accordance with ~~GAAP, as well as the calculation of realized price per REO MT:~~

~~Production Costs~~

Production Costs, which we use to calculate our key performance indicator, production cost per REO MT, is a non-GAAP financial measure. As mentioned above, production cost per REO MT is a key indicator of our production efficiency. 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:

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 ~~start-up~~ and other non-recurring costs; accretion of asset retirement and environmental obligations; gain or loss on sale or disposal of long-lived assets; ~~write-downs of inventories; tariff rebates;~~ 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:

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.

Adjusted Net Income and Adjusted Diluted EPS

We calculate Adjusted Net Income as our GAAP net income excluding the impact of ~~depletion;~~ stock-based compensation expense; start-up costs; transaction-related ~~start-up~~ and other non-recurring costs; gain or loss on sale or disposal of long-lived assets; ~~write-downs of inventories; tariff rebates;~~ 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 ~~GAAP~~adjusted diluted weighted-average shares outstanding, ~~as the denominator,~~ of ~~depletion;~~ stock-based compensation expense; start-up costs; transaction-related ~~start-up~~ and other non-recurring costs; gain or loss on sale or disposal of long-lived assets; ~~write-downs of inventories; tariff rebates;~~ 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.

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. As a result of the acquisition of Secure Natural Resources LLC, the mineral rights for the rare earth ores contained in our mine were recorded at fair value, resulting in a significant step-up of the carrying amount of the asset which caused depletion to be meaningfully higher than prior periods. While the depletion expense related to the stepped-up mineral rights asset is excluded from Adjusted Net Income and Adjusted Diluted EPS, the revenue related to such mineral rights is reflected in Adjusted Net Income and Adjusted Diluted EPS as this asset contributes to our revenue generation. 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 adjusted effective tax rates were ~~24.0%~~31.3%, ~~24.7%~~25.1%, ~~20.6%~~24.0% and ~~21.1%,~~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 ~~2021, respectively.~~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,

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,					For the six months ended June 30,

Critical Accounting Policies

A complete discussion of our critical accounting policies is included in our Form 10-K for the year ended December 31, ~~2021.~~2022. There have been no significant changes in our critical accounting policies during the three months ended June 30, ~~2022.~~2023.

Recently Adopted and Issued Accounting Pronouncements

Recently adopted and issued accounting pronouncements are described in Note 2, “Significant Accounting Policies,” in the notes to the unaudited Condensed Consolidated Financial Statements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

~~Interest rate risk~~

We had cash, cash equivalents and short-term investments totaling $1,264.1 million as of June 30, 2022, of which $1,234.5 million was invested in money market funds, U.S. Treasury and agency securities. Our cash, cash equivalents and short-term investments are held for working capital and general corporate purposes. We do not enter into investments for trading or speculative purposes.

Our cash equivalents and short-term investments are subject to market risk due to changes in interest rates. Fixed rate securities may have their market value adversely affected due to a rise in interest rates. Due in part to these factors, our future investment income may fall short of our expectations due to changes in interest rates or we may suffer losses in principal if we are forced to sell securities that decline in market value due to changes in interest rates. As our short-term investments are classified as available-for-sale, no gains are recognized due to changes in interest rates. As losses due to changes in interest rates are generally not considered to be credit related, no losses in such investments are recognized due to changes in interest rates unless we intend to sell, it is more likely than not that we will be required to sell, we sell prior to maturity, or we otherwise determine that all or a portion of the decline in fair value is due to credit related factors.

As of June 30, 2022, a hypothetical increase of 100-basis points in interest rates would not have a material impact on the value of our cash equivalents or short-term investments in our unaudited Condensed Consolidated Financial Statements.

~~With the exception of the item above, there~~There have been no material changes in our market risk exposures for the three months ended June 30, ~~2022,~~2023, as compared to those discussed in our Form 10-K for the year ended December 31, ~~2021.~~2022.

ITEM 4. CONTROLS AND PROCEDURES

The Company’s management, under the supervision and with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), as of June 30, ~~2022.~~2023. Based on this evaluation, our principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures were effective as of June 30, ~~2022,~~2023, to ensure that information required to be disclosed by the Company in reports we file or submit under the Exchange Act is (i) recorded, processed, summarized, evaluated and reported, as applicable, within the time periods specified in the United States Securities and Exchange Commission’s rules and forms and (ii) accumulated and communicated to the Company’s management, including the Company’s principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosures.

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