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 for the year ended December 31, 2024 (“Form 10-K”). This discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. The actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, including, but not limited to, those set forth under “Part II. Item 1A. Risk Factors” and elsewhere in this Form 10-Q and “Part I. Item 1A. Risk Factors” and elsewhere in our Form 10-K. See also “Cautionary Note Regarding Forward-Looking Statements.”
Business Overview
MP Materials Corp., including its subsidiaries (“we,” “our,” and “us”), is the largest producer of rare earth materials in the Western Hemisphere. We own and operate the Mountain Pass Rare Earth Mine and Processing Facility (“Mountain Pass”) located near Mountain Pass, San Bernardino County, California, the only rare earth mining and processing site of scale in North America. We are also developing a rare earth metal, alloy and magnet manufacturing facility in Fort Worth, Texas (“Independence” or the “Independence Facility”).
Our reportable segments, which are primarily based on our internal organizational structure and types of products, are our two operating segments—Materials and Magnetics. Where applicable, prior period amounts have been recast to conform to this segment reporting structure, which was modified during the fourth quarter of 2024.
The Materials segment represents our upstream and midstream operations, which primarily consist of Mountain Pass, a fully integrated mining and refining facility producing refined rare earth oxides and related products. The Materials segment generates revenue primarily from sales of neodymium-praseodymium (“NdPr”) oxide and metal, primarily sold to customers in Japan, South Korea, and broader Asia. The Materials segment historically generated the majority of its revenue from sales of rare earth concentrate primarily to a single customer in China. In April 2025, in response to China’s retaliatory tariffs and export controls, we made the strategic decision to cease shipments of rare earth concentrate to China. In July 2025, to align with the terms of the DoD Transaction Agreements (as defined below) and in further support of our domestic supply chain objectives, we agreed to cease all future sales of products to China. See the “Recent Developments” and “Liquidity and Capital Resources” sections for further details.
The Magnetics segment represents our downstream magnet manufacturing and related operations, which currently consist of the Independence Facility, a fully integrated metal, alloy, and magnet manufacturing plant, where we produce and sell magnetic precursor products and anticipate manufacturing neodymium-iron-boron (“NdFeB”) permanent magnets by the end of 2025. The Magnetics segment began generating revenue from sales of magnetic precursor products to a single customer in the U.S., in the first quarter of 2025.
Certain rare earth elements (“REE”) serve as critical inputs for the rare earth magnets inside the electric motors and generators powering carbon-reducing technologies such as hybrid and electric vehicles (referred to collectively as “xEVs”) and wind turbines, as well as drones, defense systems, robotics and many other high-growth, advanced technologies. Our integrated operations combine low production costs with high environmental standards, thereby restoring American leadership to a critical industry with a strong commitment to sustainability.
Recent Developments
Public Offering of Common Stock
On July 18, 2025, we completed an underwritten public offering, with J.P. Morgan Securities LLC and Goldman Sachs & Co. LLC. as representatives of several underwriters (collectively, the “Underwriters”), relating to the issuance of 11,818,181 shares of our common stock, par value $0.0001 per share, at a price to the public of $55.00 per share (the “Offering”). The Underwriters purchased the shares of our common stock at a price of $53.35 per share. We also granted the underwriters a 30-day option, which was exercised in full, to purchase up to an additional 1,772,727 shares of our common stock, solely to cover over-allotments, at the public offering price less the underwriting discount. Our net proceeds from the Offering are expected to be approximately $724 million, after deducting our underwriting discounts and commissions and other estimated offering expenses. We currently intend to use the net proceeds from the Offering to fund the acceleration and expansion of our
operations, including the 10X Facility (as such term is defined below), for strategic growth opportunities and for general corporate purposes.
Agreement with Apple Inc.
On July 14, 2025, we entered into a definitive, long-term supply agreement with Apple Inc. (NASDAQ: AAPL) (“Apple”) for the development, manufacture, and supply of magnets from our Independence Facility, as well as the development and installation of scaled recycling capabilities at Mountain Pass to produce the contained rare earths from post-industrial and post-consumer recycled rare earth feedstocks. In connection with the agreement, and subject to achieving specified milestones, Apple agreed to make prepayments in the aggregate amount of $200 million for the purchase of magnets from us.
Public-Private Partnership with U.S. Department of Defense
On July 9, 2025, we entered into definitive agreements (collectively, the “DoD Transaction Agreements”) establishing a transformational public-private partnership with the United States Department of Defense (the “DoD”) to accelerate the build-out of an end-to-end U.S. rare earth magnet supply chain and reduce foreign dependency (the “DoD Transactions”).
Development, Supply and Pricing Commitments
As part of the DoD Transactions, we agreed to use reasonable best efforts to build our planned 10X Magnet Manufacturing Facility (the “10X Facility”) to produce sintered NdFeB permanent magnet blocks and/or other finished magnets. Additionally, we agreed to use reasonable best efforts to (i) expand heavy rare earth elements (“HREE”) refining capacity at Mountain Pass, which, after the DoD extends the Samarium Project Loan (as defined below) to us in accordance with the DoD Transaction Agreements, will include separation of samarium oxide, (ii) recommission the chlor-alkali facilities at Mountain Pass and (iii) expand capacity at the Independence Facility to a projected 3,000 metric tons (“MTs”) of magnets annually. We have also agreed to use up to $600 million of our existing cash to fund these projects.
Under the NdPr price floor protection agreement (the “PPA”), the DoD will pay us a quarterly payment per kilogram (“KG”) of NdPr produced by us equal to the shortfall between $110 per KG and the Benchmark Quarterly Average Volume Weighted Price (as defined in the PPA). If, after the 10X Facility reaches full production capacity, the Benchmark Quarterly Average Volume Weighted Price for the prior quarter exceeds $110 per KG, the DoD will be entitled to receive 30% of the NdPr sales price which exceeds $110 per KG. The term of the PPA will commence on the first day of the fourth quarter of 2025 and will continue for ten years and will apply to all of our products that contain NdPr (i.e., concentrate, oxide and metal).
The PPA provides that we will prioritize the supply of NdPr first to magnet manufacturing, with excess volumes remaining available for sale to commercial customers, subject to a prohibition on sales to certain Restricted Buyers (as defined in the PPA) and certain other obligations.
Pursuant to the terms of the offtake agreement (the “DoD Offtake Agreement”), the DoD agreed to purchase the entire quantity of magnets produced at the 10X Facility; provided however, that up to 100% of magnet production may be syndicated to commercial and other customers under certain conditions. The DoD Offtake Agreement has a term of ten years following the Commercial Operation Date (as defined in the DoD Offtake Agreement) of the 10X Facility. In accordance with the DoD Offtake Agreement, the 10X Facility will generate at least $140 million of EBITDA (as defined in the DoD Offtake Agreement) on an annual basis after reaching full production capacity, adjusted annually in each calendar year following 2025 for inflation at a rate equal to 2% (the “Threshold EBITDA Amount”). The DoD will also acquire magnets from us at a price equal to the production costs incurred in connection with the production of magnets at the 10X Facility.
The DoD will make quarterly payments to us in an amount equal to 25% of the applicable Threshold EBITDA Amount. Once the 10X Facility begins producing magnets at target levels, in the event that any portion of the magnet production from the 10X Facility in an applicable year is syndicated to third-party purchasers, the DoD will be entitled to receive (i) the first $30 million of EBITDA attributed to the 10X Facility magnet production that exceeds the Threshold EBITDA Amount (the “Initial Excess Amount”) and (ii) 50% of the EBITDA attributable to the 10X Facility magnet production that exceeds the Initial Excess Amount on an annual basis in that year. Before the Commercial Operation Date, the DoD will also make payments in respect of certain incremental costs incurred by us including in connection with the engineering, development and start up of the 10X Facility and for designing magnets to the DoD’s specifications, with such payments being capped at $30 million in any calendar year. The DoD Offtake Agreement also prohibits magnet sales to certain Restricted Buyers and imposes certain other obligations.
We also agreed to terminate our existing share repurchase program and to cease making sales under the Shenghe Offtake Agreement (as defined in Note 19, “Related-Party Transactions,” in the notes to the unaudited Condensed Consolidated Financial Statements), which expires in January 2026, and will not be renewed.
Financings
As part of the financing for the projects described above, we sold to the DoD $400 million of newly created Series A Cumulative Perpetual Convertible Preferred Stock, par value $0.0001 per share (the “Series A Preferred Stock”). The Series A Preferred Stock is convertible by the initial holder thereof at any time and from time to time after 45 days of issuance into approximately 13.3 million shares of our common stock, subject to customary adjustments for stock splits, combinations, non-cash dividends and certain corporate transactions.
Shares of the Series A Preferred Stock accrue cumulative dividends at a rate of 7.0% per year (the “Dividend Rate”), compounding quarterly and payable solely in-kind through an increase to the stated value of each share of Series A Preferred Stock (each such Dividend, a “PIK Dividend”). While the terms of the Series A Preferred Stock do not restrict the payment of cash dividends by the Company, within the first 15 business days of each new fiscal year, we will pay to the holder of each share of Series A Preferred Stock, on an as-converted basis, cash per share of common stock representing the amount, if any, by which the annual yield of the aggregate cash dividends paid by us on each share of common stock in the prior fiscal year exceeded the Dividend Rate.
At any time after the five year anniversary of issuance, if the closing price per share of common stock exceeds 150% of the then-current conversion price for at least 20 trading days in any period of 30 consecutive trading days, we will have the option to require all or any portion of the then-outstanding shares of Series A Preferred Stock be converted into common stock at the then-current conversion price, subject to certain liquidity and other conditions.
We also issued a warrant (the “Warrant”) to the DoD, exercisable at any time and from time to time after 45 days of issuance for a period of 10 years for up to 11,201,659 shares of our common stock, at an initial exercise price of $30.03 per share, such price subject to certain anti-dilution adjustments. In the aggregate, the common stock into which the Series A Preferred Stock is initially convertible and for which the Warrant is initially exercisable collectively represent 15% of the issued and outstanding shares of our common stock as of July 9, 2025 without giving effect to the issuance of such shares.
In addition to the issuance of securities, JPMorgan Chase Funding Inc. and Goldman Sachs Bank USA agreed to provide committed secured financing, subject to customary terms and conditions, in an amount equal to, in the aggregate, at least $1 billion, $650 million of which will, pursuant to the terms of the committed secured financing, be specifically allocated to the construction of the 10X Facility; provided, that such $1 billion may be reduced on a dollar-for-dollar basis for certain equity and/or debt raises (including the proceeds from the Offering discussed above) and certain unrestricted cash that is not segregated or otherwise earmarked for use as contemplated by the DoD Transaction Agreements.
We also received a loan from the DoD in the aggregate principal amount of $150 million (the “Samarium Project Loan”), pursuant to an unsecured promissory note (the “Promissory Note”) maturing 12 years after issuance. Interest will accrue on the Samarium Project Loan at a rate equal to the 10-year U.S. Treasury constant maturity rate plus 1.00% and will be payable in cash quarterly in arrears.
One Big Beautiful Bill Act
On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted into law. Among other provisions, the OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act and the phase-out of the Section 45X Advanced Manufacturing Production Credit (the “45X Credit”) by 2034. We are currently evaluating the impact of the OBBBA on our business, results of operations and financial position, and the results of such evaluations will be reflected in our unaudited Condensed Consolidated Financial Statements in the third quarter of 2025, the period in which the OBBBA was enacted.
VREX Holdco Equity Method Investment Exit
During the second quarter 2025, after all required regulatory approvals were received, we sold our 49% interest in VREX Holdco Pte. Ltd. (“VREX Holdco”) back to VREX Holdco in exchange for a cash payment equal to our initial investment amount of $9.7 million. See Note 6, “Equity Method Investment,” in the notes to the unaudited Condensed Consolidated Financial Statements for additional information.
Cessation of Shipments to China and Stockpiling of Rare Earth Concentrate
In response to China’s retaliatory tariffs and export controls introduced in April 2025, we announced the strategic decision to cease shipments of rare earth concentrate to China. Historically, through our Materials segment, we sold the vast majority of our rare earth concentrate to a single, principal customer in China under the terms of the Shenghe Offtake Agreement. In July 2025, to align with the terms of the DoD Transaction Agreements and in further support of our domestic supply chain objectives, we ceased all further sales of our products to China and determined we would not exercise our right to extend the term of the Shenghe Offtake Agreement when it expires in January 2026.
We continue to produce concentrate, and to the extent not sold or further processed and sold as separated product, we will stockpile that concentrate for future use. In addition, we are prioritizing accelerating our downstream operations, as well as focusing on generating sales of separated products to customers.
The cessation of shipments had, at least in the short-term, a material negative impact on our business, operating results, financial performance and financial condition, cash flows and liquidity.
Factors Affecting Our Performance
We believe we are uniquely positioned to capitalize on the trends of electrification and supply chain security, particularly as domestic xEV production and domestic industrial supply chain initiatives grow. Our continued success depends to a significant extent on our ability to take advantage of the following opportunities and meet the challenges associated with them.
Demand for REE
The key demand drivers for REE are a diverse array of growing end markets, including electric mobility; physical AI; industrial, consumer and professional service robotics; renewable power generation; energy-efficient motors, pumps, and compressors; consumer and medical applications; critical defense systems; and catalysts and phosphors. Accordingly, the demand for our products may be impacted by demand for these downstream products, particularly the continued growth in xEVs. Despite the current macroeconomic conditions, we continue to believe that we benefit from the growth of the rare earth market, particularly the market for NdPr and permanent magnets, and from several demand tailwinds for REE. These include the trend toward electrification; implementation of physical AI; geographic supply chain diversification, particularly in relation to China; the U.S. government initiatives to restore domestic supply of critical minerals; and the increasing requirement for environmentally-conscious production methods.
Furthermore, as mentioned in the “Recent Developments” section above, in April 2025, China imposed export controls, which included export restrictions on seven heavy REE and certain magnet materials containing heavy REE. The new restrictions require companies to secure special export licenses to export the specified REE and magnet materials containing heavy REE. This development has led to several market trends, which may or may not be permanent, including disruptions in supply chains, shortages of rare earth elements, potential price volatility, and an increased demand for alternative supply chains outside of China, all of which, if sustained, may have a material impact on the demand for our products.
Changes in technology could reduce the use of REE, including NdPr, in the components in which they are now used, or lead to a decline in reliance on such components altogether. Additionally, export controls and supply chain disruptions may also incentivize companies and governments to build alternative supply chains and create economic pressure to identify or create alternate technologies that ultimately could depress long-term demand for rare earth minerals and products, and at the same time may incentivize development of competing mining properties. Actual, or perceived, decreases in demand for REE, whether through changes in technology or slower growth in the end markets that utilize REE, could result in a decline in the market price of REE, including NdPr, and/or result in pricing volatility. We also operate in a competitive industry. Many of our key competitors are based in China, where competitors may not be subject to the same rigorous environmental standards or may receive disproportionate government subsidies, and production costs are typically lower than in the U.S.
Maximizing Upstream (“Stage I”) and Midstream (“Stage II”) Production Efficiency
Following the implementation of our Stage I optimization plan, we have achieved at least 40,000 MTs of annual REO Production Volume since 2021. These results were achieved by optimizing the reagent scheme, reducing process temperatures, improving tailings facility management, and committing to operational excellence, which allowed us to achieve record production levels in 2024 and the first half of 2025. Our Stage I optimization plan has enabled us to achieve what we believe to be world-class production cost levels for rare earth concentrate.
In November 2023, we announced our “Upstream 60K” strategy whereby we intend to grow our annual REO Production Volume to approximately 60,000 MTs by expanding upstream capacity via investments in further beneficiation, including the ability to process alternative feedstocks and upgrade lower-grade feedstocks. We aim to achieve this initiative within the next three years with modest incremental capital investment.
Stage II advanced our operations from the production of rare earth concentrate to the separation of individual REE. The Stage II optimization project incorporated upgrades and enhancements to the prior facility process flow to produce separated REE at a lower cost while minimizing our impact on the environment. More specifically, we have reintroduced an oxidizing roasting circuit, reoriented portions of the plant process flow, increased product finishing capacity, improved wastewater management, and made other improvements to materials handling and storage. The reintroduction of the oxidizing roasting circuit allows subsequent stages of the production process to occur at lower temperatures, and with lower volumes of materials and reagents, which supports lower operating and maintenance costs and higher uptime than would otherwise be achievable.
The success of our business reflects our ability to continue to manage our costs and drive scale. Our upstream production achievements have provided economies of scale to lower production costs per MT of REO produced in concentrate. Furthermore, we designed our midstream process flow to capitalize on the inherent advantages of the bastnaesite ore at Mountain Pass, which is well-suited to low-cost refining by selectively eliminating the need to carry cerium, a lower-value element, through the separations process. Additionally, our location and integration offer cost and transportation advantages that create meaningful efficiencies in production, security of incoming supplies and shipping of our final products.
During the second half of 2023, we began producing separated rare earth products. We continue to expect that it may take many quarters to achieve our designed throughput of separated products. As we increase production of separated products over time, we expect to reduce our per-unit production costs of NdPr oxide, which represents a majority of the value contained in our concentrate. Until such time, we may experience unstable operations and elevated costs of our initial production of separated products.
As part of our partnership with the DoD, we have committed to further expand our refining capacity to include the separation of samarium oxide and to expand and recommission the chlor-alkali facilities at Mountain Pass. Additionally, as part of our agreement with Apple, we will continue to develop and install scaled recycling capabilities at Mountain Pass.
We currently generate our revenue primarily from our Materials segment, which operates a single site in a single location, and any stoppage in activity, including for reasons outside of our control, could adversely impact our production, results of operations and cash flows.
Development of Our Downstream Manufacturing Capabilities (“Stage III”)
We are completing the installation of equipment at Independence and continue to develop engineering and manufacturing technology to process NdPr metal into magnets, while incorporating magnet recycling capabilities. These initiatives support our long-term plans to become a leading global source for rare earth magnets. We believe this vertical integration is a core competitive advantage in the production of a critical industrial output. We expect our downstream manufacturing efforts to continue to benefit from geopolitical developments, including initiatives to repatriate critical materials supply chains, such as through our agreements with the DoD and Apple described in the “Recent Developments” section above.
In December 2024, we commissioned our electrowinning capability to produce NdPr metal from NdPr oxide at Independence. Further, we introduced capabilities to produce neodymium-praseodymium-iron-boron alloy flake, a key precursor product that is utilized as the material feedstock for magnet manufacturing. In addition, we recently began trial production of automotive-grade, sintered NdFeB magnets at our new product introduction (“NPI”) facility within Independence. We began generating revenue from sales of magnetic precursor products in the first quarter of 2025. We expect to continue generating revenue from these sales ahead of commissioning of our magnet manufacturing capabilities at the Independence Facility, which are targeted to enter service at the end of 2025. As part of our partnership with the DoD, we committed to continue the expansion in capacity of the Independence Facility to a projected 3,000 MTs of magnets annually
and to commence construction of the 10X Facility. Following commissioning of these capabilities and qualification of our finished magnets, we expect to generate revenue primarily from the sale of finished magnets.
While we have grown increasingly confident about our future outlook with the progress made to-date, there are inherent risks in finalizing construction and developing the process technology for magnet manufacturing. For instance, unforeseen delays in construction or the installation of specific equipment may occur, or our products may fail to satisfy customer expectations, which could adversely affect both the amount and timing of our revenue from permanent magnets and precursor products.
Our Mineral Reserves
Our ore body has proven over more than 60 years of operations to be one of the world’s largest and highest-grade rare earth resources. As of December 31, 2024, SRK Consulting (U.S.), Inc., an independent consulting firm that we retained to assess our reserves, estimated total proven and probable reserves of 2.04 million short tons of REO contained in 29.69 million short tons of ore at Mountain Pass, with an average ore grade of 5.97%. These estimates use an estimated economical cut-off grade of 2.50% total rare earth oxide. Based on these estimated reserves and our expected annual production rate of REO upon production ramp-up of our midstream operations, our expected mine life was approximately 29 years as of December 31, 2024. Over time, we expect to be able to continue to grow our expected mine life through additional exploratory drilling and improved processing capabilities, which may result in changes to various assumptions underlying our mineral reserve estimate.
Mining activities in the U.S. are heavily regulated, particularly in California. Regulatory changes may make it more challenging for us to access our reserves. In addition, new mineral deposits may be discovered elsewhere, which could make our operations less competitive.
Key Performance Indicators
In evaluating the performance of our Materials segment, we use the key performance indicators (“KPIs”) outlined below. Our calculations of these KPIs may differ from similar measures published by other companies in our industry or in other industries. See the “Materials Segment” section below for further discussion of year-over-year changes in KPIs. Since the Magnetics segment only recently commenced production, we have not established any KPIs for its operations.
REO Production Volume
We measure our REO-equivalent production volume for a given period in MTs, our principal unit of sale for our concentrate product. This measure refers to the REO content contained in the rare earth concentrate we produce and, beginning in the second quarter of 2023, includes volumes fed into downstream circuits for commissioning and starting up our separations facilities and for producing separated rare earth products, a portion of which is also included in our KPI, NdPr Production Volume. REO Production Volume is a key indicator of the mining and processing capacity and efficiency of our upstream operations.
The rare earth concentrate is a processed, concentrated form of our mined rare earth-bearing ores. While our unit of production and sale is a MT of contained REO, the actual weight of our rare earth concentrate is significantly greater, as the concentrate also contains non-REO minerals, loss-on-ignition, and residual moisture from the production process. We target REO content of greater than 60% per dry MT of concentrate (referred to as “REO grade”). The elemental distribution of REO in our concentrate is relatively consistent over time and production lot. We consider this the natural distribution, as it reflects the distribution of elements contained, on average, in our ore.
REO Sales Volume
Our REO Sales Volume for a given period is calculated in MTs. A unit, or MT, is considered sold once we recognize revenue on its sale as determined in accordance with generally accepted accounting principles in the United States (“GAAP”). Our REO Sales Volume is a key measure of our ability to convert our concentrate production into revenue. Our REO Sales Volume includes both traditional concentrate as well as roasted concentrate. Given our cessation of shipments of concentrate as discussed in the “Recent Developments” section above, we do not expect historical REO Sales Volume to be representative of future volumes.
Realized Price per REO MT
We calculate the Realized Price per REO MT for a given period as the quotient of: (i) our rare earth concentrate sales, which are determined in accordance with GAAP, for a given period and (ii) our REO Sales Volume for the same period. Realized Price per REO MT is an important measure of the market price of our concentrate product.
NdPr Production Volume
We measure our NdPr Production Volume for a given period in MTs, our principal unit of sale for our NdPr separated products. NdPr Production Volume refers to the volume of finished and packaged NdPr oxide produced at Mountain Pass for a given period. NdPr Production Volume is a key indicator of the separating and finishing capacity and efficiency of our midstream operations.
NdPr Sales Volume
Our NdPr Sales Volume for a given period is calculated in MTs and on an NdPr oxide-equivalent basis (as further discussed below). A unit, or MT, is considered sold once the Materials segment recognizes revenue on its sale, whether sold as NdPr oxide or NdPr metal, as determined in accordance with GAAP. For these NdPr metal sales, the MTs sold and included in NdPr Sales Volume are calculated based on the volume of NdPr oxide used to produce such NdPr metal. We utilize an assumed material conversion ratio of 1.20, such that a sale of 100 MTs of NdPr metal would be included in this KPI as 120 MTs of NdPr oxide-equivalent. NdPr Sales Volume is a key measure of our ability to convert our production of separated NdPr products into revenue. In the future, NdPr Sales Volume for the Materials segment is expected to include sales made to the Magnetics segment.
For the Materials segment, we have a mix of contracts with customers where we sell NdPr as (i) oxide, (ii) metal, where the amount of oxide required to produce such metal is variable, and (iii) metal, where we have a guarantee of the amount produced and sold based on the amount of oxide consumed. Among other factors, differences between quarterly NdPr Production Volume and NdPr Sales Volume may be caused by the time required for the conversion of NdPr oxide to NdPr metal, including time in-transit, as well as differences in actual versus assumed yields of oxide to metal in the calculation of NdPr Sales Volume.
NdPr Realized Price per KG
We calculate the NdPr Realized Price per KG for a given period as the quotient of: (i) our Materials segment NdPr oxide and metal sales, which are determined in accordance with GAAP, for a given period and (ii) our NdPr Sales Volume for the same period. NdPr Realized Price per KG is an important measure of the market price of our NdPr products. In the future, NdPr Realized Price per KG for the Materials segment is expected to include sales made to the Magnetics segment.

Revenue
Rare earth concentrate revenue consists of sales of traditional and roasted rare earth concentrate. For the majority of our sales of rare earth concentrate, the sales price is based on a preliminary market price (net of taxes, tariffs, and certain other agreed charges) per MT, with an adjustment for the ultimate market price of the product realized upon final sale, including the impact of changes in the exchange rate between the Chinese Yuan and the U.S. dollar.
NdPr oxide and metal revenue consists of sales of NdPr oxide and metal produced at Mountain Pass under individual sales agreements, as well as sales under our distribution agreement with Sumitomo Corporation of Americas. As we ramp up production of separated rare earth products, we expect our NdPr oxide and metal revenue to become a larger portion of our total revenue. Accordingly, to the extent we sell a greater volume of NdPr oxide and NdPr metal, rare earth concentrate revenue will decline in future periods.
Magnetic precursor products consists of sales of magnetic precursor products, including NdPr metal, produced at the Independence Facility and sold in the U.S. Sales of these products commenced in the first quarter of 2025 pursuant to a long-term supply agreement with GM.

Total revenue increased for the three and six months ended June 30, 2025, as compared to the respective prior year periods, as a result of ramping production of separated products throughout 2024, resulting in higher NdPr oxide and metal revenue in the current year. Additionally, during the three and six months ended June 30, 2025, we began recognizing revenue from the sales of magnetic precursor products, with no comparable revenue in the respective prior year periods. These increases were partially offset by the decreases in rare earth concentrate revenues, impacted by the strategic decision to cease shipments of rare earth concentrate to China as well as by the ramp-up in midstream operations, where a significantly higher portion of REO produced was refined and sold as NdPr oxide and metal during the current year period. As a result of the items discussed in the “Recent Developments” section above, we expect our rare earth concentrate revenues to be materially lower in future periods as we prioritize further processing the concentrate into separated rare earth products or stockpiling for future use. See the “Segment Results” section below for further discussion of year-over-year changes in revenue.
Cost of sales (excluding depreciation, depletion and amortization)
Cost of sales (excluding depreciation, depletion and amortization) (“COS”) consists of mining, processing, separations, and metal making-related labor costs (including wages and salaries, benefits, bonuses, and stock-based compensation); mining, processing, separations, and metal making-related supplies and reagents; parts and labor for the maintenance of our mining fleet and processing and separating facilities; other facilities-related costs (such as property taxes and utilities); packaging materials; and shipping and freight costs.

| (in thousands, except percentages) | 2025 | 2024 | $ | % | 2025 | 2024 | $ | % | |||||||||||||||||||||||||||||||||||||||
| Cost of sales (excluding depreciation, depletion and amortization) | $ | 50,431 | $ | 41,463 | $ | 8,968 | 22 | % | $ | 99,262 | $ | 77,057 | $ | 22,205 | 29 | % |
The increases in COS for the three and six months ended June 30, 2025, were driven by higher sales of NdPr oxide and metal in the current year periods, as discussed above, offset partially by a decline in per-unit production costs associated with separated rare earth products as we continue to optimize production. Notwithstanding, per-unit production costs of separated products are necessarily higher than those of rare earth concentrate due to the additional processing required. Such costs pertain primarily to chemical reagents, employee labor, maintenance expenses, and consumables.
The year-over-year increases are further impacted by the production costs associated with the magnetic precursor products sold in the current year, specifically NdPr metal at the Independence Facility, with no comparable costs in the prior year. Lastly, COS for the three and six months ended June 30, 2025, benefited from (i) a lower reserve on certain of our work in process and finished goods inventories, which decreased by $8.3 million and $11.1 million, respectively, when compared to the respective prior year periods; (ii) $1.9 million and $4.7 million, respectively, of higher 45X Credit impacts in the respective current year periods; and (iii) $1.9 million in lower repairs and maintenance expenses, attributable to thickener equipment damage costs incurred in the second quarter of 2024.
As we produce and sell more separated products at Mountain Pass, we expect that COS may continue to increase throughout 2025 even as certain per-unit production efficiencies and economies of scale are expected to be achieved, primarily due to the higher production costs associated with separated rare earth products versus rare earth concentrate, as discussed above. Accordingly, in future periods, any further increase in sales of NdPr oxide and metal will likely result in higher year-over-year COS. Additionally, should we further ramp the production of magnetic precursor products at Independence, COS would also increase.
Selling, general and administrative
Selling, general and administrative (“SG&A”) expenses consist primarily of personnel costs (including salaries, benefits, bonuses, and stock-based compensation) of our administrative functions such as executives, accounting and finance, legal, and information technology; professional services (including legal, regulatory, audit and others); certain engineering expenses; insurance, license and permit costs; corporate office lease cost; office supplies; and certain environmental, health and safety expenses.

The increases in SG&A expenses for the three and six months ended June 30, 2025, as compared to the respective prior year periods, were driven primarily by higher legal costs. Additionally, higher personnel costs (excluding stock-based compensation expense, which decreased modestly) contributed $2.4 million and $3.4 million, respectively, of the increase in the current respective year periods, due to higher executive and administrative personnel costs, as well as increased employee headcount to support our downstream expansion.
Depreciation, depletion and amortization
Depreciation, depletion and amortization (“DD&A”) primarily consists of depreciation of property, plant and equipment and depletion of mineral rights.

The year-over-year increases in DD&A for the three and six months ended June 30, 2025, primarily reflect increases in depreciation of $4.0 million and $7.3 million, respectively. Depreciation increased as a result of the timing of placing certain machinery and equipment assets into service, which occurred progressively throughout 2024, with the majority placed into service during the fourth quarter of 2024 as we began production of magnetic precursor products at Independence.
Start-up costs
Start-up costs relate to costs associated with restarting an existing facility or commissioning a new facility, circuit or process of our production, manufacturing, or separations facilities prior to the achievement of commercial production, that do not qualify for capitalization. Such costs, which are expensed as incurred, include certain salaries and wages, outside services, parts, training, and utilities, among other items, used or consumed directly in these start-up activities.

The year-over-year decreases in start-up costs for three and six months ended June 30, 2025, were attributable primarily to our midstream operations, where start-up activities have been completed as production of separated products commenced in late 2023. Start-up costs attributable to our downstream initiatives decreased year over year, in line with the commencement of our production of magnetic precursor products at Independence in late 2024.
Advanced projects and development
Advanced projects and development consists principally of costs incurred in connection with research and development of new processes or to significantly enhance our existing processes; and certain government contracts, as well as costs incurred to support growth initiatives or pursue other opportunities.
| For the three months ended June 30, | Change | For the six months ended June 30, | Change | ||||||||||||||||||||||||||||||||||||||||||||

The year-over-year increase in advanced projects and development for the three months ended June 30, 2025, was primarily due to higher transaction costs, largely associated with the transactions described in the “Recent Developments” section above. The year-over-year decrease for the six months ended June 30, 2025, was driven by (i) lower research and development costs, attributable to the start of production of magnetic precursor products at the Independence Facility during the first quarter of 2025, and (ii) $1.4 million in lower costs incurred for legal, consulting, and advisory services to support growth initiatives, such as potential acquisitions, mergers, or other investments.
Other operating costs and expenses (income), net
Other operating costs and expenses (income), net consists primarily of accretion of asset retirement and environmental obligations and gains or losses on disposals of long-lived assets, including demolition costs.

| N/M = Not meaningful. |
The year-over-year changes were attributed primarily to the net impact of gains recognized on sales of certain long-lived assets during the three and six months ended June 30, 2025.
Interest expense, net
Interest expense, net principally consists of the expense associated with the 0.25% and 3.00% per annum interest rates and amortization of the debt issuance costs on our 2026 Notes and 2030 Notes (as defined below), respectively, offset by capitalized interest.

Interest expense, net for the three months ended June 30, 2025, decreased year over year primarily due to higher capitalized interest in the current year period. Interest expense, net for the six months ended June 30, 2025, increased year over year due to the issuance of the 2030 Notes, partially offset by repurchases of the 2026 Notes in 2024 and by higher capitalized interest in the current year period.

Gain on early extinguishment of debt during the six months ended June 30, 2024, was the result of the repurchase of a portion of our 2026 Notes at prices lower than the associated carrying amounts. See the “Liquidity and Capital Resources” section below for additional information.
Other income, net
Other income, net consists of interest and investment income, changes in fair value of derivative instruments, and non-operating gains or losses.

Other income, net for the three and six months ended June 30, 2025, decreased year over year primarily as a result of lower interest and investment income earned on our short-term investments, whose balance decreased over the applicable periods. Interest and investment income is principally generated from accretion of the discount on such investments. Additionally, Other income, net was impacted by the changes in the fair value of the derivative instrument related to the redemption feature included in the portion of the 2030 Notes issued in December 2024, which was a $2.5 million loss and a $4.5 million gain for the three and six months ended June 30, 2025, respectively. Finally, both the three and six months ended June 30, 2025, benefited from a gain of $1.3 million related to the disposition of the VREX Holdco equity method investment.
Income tax benefit
Income tax expense or benefit consists of an estimate of U.S. federal and state income taxes in the jurisdictions in which we conduct business, adjusted for federal, state and local allowable income tax benefits, the effect of permanent differences and any valuation allowance against deferred tax assets.

The effective tax rate for the three and six months ended June 30, 2025, differed from the statutory tax rate of 21% primarily due to the 45X Credit, percentage depletion, and state income tax benefit, offset by a deduction limitation on officers’ compensation and a valuation allowance on California Competes Tax Credits (“CCTC”). The effective tax rate for the three and six months ended June 30, 2024, differed from the statutory tax rate of 21% primarily due to state income tax expense and a deduction limitation on officers’ compensation, offset by the 45X Credit and CCTC. For additional information on the 45X Credit, see Note 15, “Government Grants,” in the notes to the unaudited Condensed Consolidated Financial Statements.

The year-over-year decreases in rare earth concentrate revenue for the three and six months ended June 30, 2025, were primarily driven by the decreases in REO Sales Volume impacted by the strategic decision to cease shipments of rare earth concentrate to China as well as the ramp-up in midstream operations, where a significantly higher portion of REO produced was refined and sold as NdPr oxide and metal during the current year period. This was partially offset by a higher Realized Price per REO MT. As noted above in the “Factors Affecting our Performance” section, market prices for rare earth products may be volatile due to actual or perceived changes in supply or demand.
Until we commenced our midstream operations, our REO Sales Volume generally tracked our REO Production Volume over time with slight period-to-period differences caused by the timing of shipments. However, as we continue to ramp up production of separated rare earth materials, we expect that significant volumes of REO produced from upstream operations will continue to be consumed for separation and not sold as concentrate. In addition, a significant portion of the contained cerium in the REO produced will be intentionally rejected and may not result in finished product. Accordingly, we continue to expect that REO Sales Volume will be significantly lower than REO Production Volume and we expect our rare earth concentrate revenues to be materially lower in future periods as we prioritize further processing the concentrate into separated rare earth products or stockpiling for future use.
The increases in NdPr oxide and metal revenue for the three and six months ended June 30, 2025, as compared to the respective prior year periods, was primarily driven by higher NdPr Production Volume as a result of ramping production of separated products throughout 2024. NdPr oxide and metal revenue for the three months ended June 30, 2025, also benefited from higher NdPr Realized Price per KG as compared to the prior year period. We currently expect to begin intersegment sales of NdPr oxide to the Magnetics segment starting in the second half of 2025.
The improvement in Materials Segment Adjusted EBITDA for the three and six months ended June 30, 2025, when compared to the respective prior year periods, were primarily due to the net increases in revenue, as discussed above, with the six months ended June 30, 2025, comparable period being partially offset by higher cost of sales (excluding depreciation, depletion and amortization and stock-based compensation expense) (“Segment COS”).
While the year-over-year Segment COS remained relatively flat for the comparable three months ended June 30, 2025, the increase in Segment COS for the six months ended June 30, 2025, was driven primarily by higher production costs associated with separated rare earth products sold in the current year period, which are currently elevated as we continue to ramp and optimize production of separated products toward normalized capacity. Segment COS for the three and six months ended June 30, 2025, benefited from (i) lower reserves on certain of our work in process and finished goods inventories, which decreased by $8.3 million and $11.1 million, respectively, when compared to the respective prior year periods; (ii) $1.9 million and $4.7 million, respectively, of higher 45X Credit impacts in the respective current year periods; and (iii) $1.9 million in lower repairs and maintenance expenses, attributable to thickener equipment damage in the second quarter of 2024.
Magnetics Segment
The Magnetics segment operates the Independence Facility, where we produce and sell magnetic precursor products and anticipate the manufacturing of NdFeB permanent magnets by the end of 2025. Pursuant to the long-term supply agreement with GM, we received prepayments of $50.0 million in April 2025 and $100.0 million during the year ended December 31, 2024, for magnetic precursor products.

We began generating revenue from sales of magnetic precursor products during the first quarter 2025, with no comparable sales during the prior year periods (see Note 14, “Revenue Recognition,” in the notes to the unaudited Condensed Consolidated Financial Statements for additional information), which also drove the year-over-year increase in Magnetics Segment Adjusted EBITDA. We continue to expect that the historical trend of Magnetics Segment Adjusted EBITDA will be significantly impacted by the production ramp of magnetic precursor products.
Corporate Expenses and Other
Corporate expenses and other is primarily comprised of the operating results of other business activities that excludes our Materials and Magnetics segments and includes costs incurred at the corporate level that are not allocated to the operating
segments, specifically relating to executive compensation, investor relations, other corporate costs, and unallocated shared service functions such as legal, information technology, human resources, finance and accounting and supply chain. Corporate expenses and other excludes stock-based compensation expense.

The increases in corporate expenses and other for the three and six months ended June 30, 2025, as compared to the respective prior year periods, was primarily due to higher personnel costs (other than stock-based compensation expense) related to executives and administrative personnel.
Quarterly Performance Trend
While our business is not highly seasonal in nature, we sometimes experience a timing lag between production and sales, which may result in volatility in our results of operations between periods. The timing lag may be the result of, or influenced by, factors such as the timing and duration of shipments or the time required to convert materials. In addition, quarterly production of concentrate and separated products is impacted by the timing of scheduled outages of our production facilities for maintenance, which typically occur in the second and fourth quarters. Finally, since we began production of separated rare earth materials in the second half of 2023, certain volumes of REO produced are further processed or rejected rather than sold as concentrate.

Liquidity and Capital Resources
Liquidity refers to our ability to generate sufficient cash flows to meet the cash requirements of our business operations, including working capital and capital expenditure needs, contractual obligations, debt service and other commitments. Since becoming a public company, our principal sources of liquidity have been the issuance of the 2026 Notes in March 2021, and net cash from operating activities. In addition, we issued the 2030 Notes in March 2024, resulting in net proceeds of $731.4 million prior to the use of a portion of these funds to repurchase the 2026 Notes, repurchase shares of our common stock, and purchase Capped Call Options, as discussed below. As of June 30, 2025, we had $753.7 million of cash, cash equivalents and short-term investments and $930.5 million of principal amount of long-term debt, including $67.7 million classified as current.
Historically, our results of operations and cash flows have depended in large part upon the market prices of rare earth products. Rare earth concentrate is not quoted on any major commodities market or exchange and demand is currently constrained to a relatively limited number of refiners, a significant majority of which are based in China. Uncertainty exists as to the market price of rare earth products primarily due to concerns over the global economic conditions and actual or perceived concerns over increases in the supply of and/or decreases in demand for rare earth products. For example, the significant decrease in the market price of rare earth products in 2024 negatively impacted our cash flows from operations and liquidity.
In response to China’s retaliatory tariffs and export controls introduced in April 2025, we announced the decision to cease shipments of rare earth concentrate to China and in July 2025, to align with the terms of the DoD Transaction Agreements and in further support of our domestic supply chain objectives, we ceased all further sales of our products to China and determined
we would not exercise our right to extend the term of the Shenghe Offtake Agreement when it expires in January 2026. We continue to prioritize further processing concentrate into separated rare earth products or stockpiling for future use.
Accordingly, the cessation of shipments to China had, at least in the short-term, a material negative impact on our results of operations and cash flows. However, we expect this negative impact to be significantly reduced once the NdPr price protection component of the DoD Transactions begins in the fourth quarter of 2025 and provides us with pricing stability. We continue to believe that our cash flows from operations and cash on hand are adequate to meet our liquidity requirements for the foreseeable future. Specifically, as part of the DoD Transactions, we received significant cash investments and future commitments from the DoD, and in July 2025, we also received a prepayment commitment from Apple, while raising approximately $724 million in net proceeds in the Offering. See the “Recent Developments” section for additional information.
While the DoD Transactions, together with our supply agreements with Apple and GM, provide a measure of certainty with respect to both near- and longer-term demand for our products and related revenues, significant factors remain which could negatively impact our liquidity, particularly in the longer-term, many of which remain largely uncertain and dependent on future developments that cannot be accurately predicted at this time, such as: our ability to accelerate our downstream operations and expansion, achieve our business milestones, and perform the obligations under our customer supply agreements; further actions that the U.S. government may take in encouraging domestic production of critical minerals and reducing reliance on foreign imports; and further changes in trade policies in the United States, China or other countries, including the implementation of new tariffs, increases in or reductions of existing tariffs, or the taking of other actions.
Our current working capital needs relate mainly to our mining, beneficiation, and separation operations. Our working capital needs have increased materially as we have ramped up the production and sales of separated rare earth products; our working capital needs have also increased as a result of the DoD Transactions and our agreement with Apple, and we expect those needs may continue to see further increases in 2025 as we continue to scale production of separated rare earth products and advance our downstream magnetics initiatives, including the production and sales of magnetic precursor products, as well as commissioning of our magnet manufacturing capabilities.
The completion of our mission to become a fully integrated domestic magnetics producer is expected to be capital intensive. Our principal capital expenditure requirements relate mainly to further investment in Mountain Pass, including the development of the HREE Facility, Upstream 60K, and other growth and investment projects, completing the buildout of Independence, as well as periodic repairs and maintenance of mining and rare earth processing equipment. Prior to the consideration of capital expenditures related to our July 2025 announcements, we expect to spend between $150 million and $175 million of capital costs in 2025 (net of any proceeds from government awards received). Our future capital requirements will also depend on several other factors, including market conditions, de-bottlenecking initiatives, decisions regarding downstream production capability, and potential acquisitions.
Our estimated costs or estimated time to complete and commission these projects may increase, potentially significantly, due to factors outside of our control. While we believe that we have sufficient cash resources to fund these initiatives and operating working capital in the near term, we cannot assure this. If our available resources prove inadequate to fund our plans or commitments, we may be forced to revise our strategy and business plans or could be required, or elect, to seek additional funding through public or private equity or debt financings; however, such funding may not be available on terms acceptable to us, if at all. Any delays in our ongoing capital projects or substantial cost increases, including construction costs and related materials costs related to their execution, could significantly impact our ability to maximize our revenue opportunities and adversely impact our business and cash flows.
Debt and Other Long-Term Obligations
2026 Notes: In March 2021, we issued $690.0 million in aggregate principal amount of 0.25% unsecured convertible senior notes (the “2026 Notes”) at a price of par. Interest on the 2026 Notes is payable on April 1st and October 1st of each year, beginning on October 1, 2021.
Contemporaneous with the pricing of the 2030 Notes, we entered into privately negotiated transactions with certain holders of the 2026 Notes to repurchase $400.0 million in aggregate principal amount of the 2026 Notes, using $358.0 million of the net proceeds from the offering of the 2030 Notes. The price we paid to repurchase the 2026 Notes, 89.5% of par value, was the same for each lender and approximated the trading price of the 2026 Notes at the time of the repurchases. Subsequent to the issuance of the 2030 Notes, we repurchased an additional $80.0 million in aggregate principal amount of the 2026 Notes in open market transactions for $70.6 million. As a result of these repurchases, we recorded a $46.3 million gain on early extinguishment of debt in the first quarter of 2024.
The remaining 2026 Notes outstanding mature, unless earlier converted, redeemed or repurchased, on April 1, 2026, and become convertible at the option of the holder beginning on January 1, 2026, through the business day immediately preceding the maturity date. The initial conversion price of the remaining 2026 Notes is approximately $44.28 per share, or 22.5861 shares per $1,000 principal amount of notes, subject to adjustment upon the occurrence of certain events.
In March 2024, we provided a written notice to the trustee and the holders of the 2026 Notes that we have irrevocably elected to fix the settlement method for all conversions that may occur subsequent to the election date, to a combination of cash and shares of our common stock with the specified dollar amount per $1,000 principal amount of the 2026 Notes of $1,000. As a result, for any conversions of 2026 Notes occurring after the election date, a converting holder will receive (i) up to $1,000 in cash per $1,000 principal amount of the 2026 Notes and (ii) shares of our common stock for any conversion consideration in excess of $1,000 per $1,000 principal amount of the 2026 Notes converted. Prior to the election being made, we could have elected to settle the 2026 Notes in cash, shares of our common stock or a combination thereof.
2030 Notes: In March 2024, we issued $747.5 million in aggregate principal amount of 3.00% unsecured convertible senior notes that mature, unless earlier converted, redeemed or repurchased, on March 1, 2030 (the “2030 Notes” and, together with the 2026 Notes, the “Convertible Notes”), at a price of par. Interest on the 2030 Notes is payable on March 1st and September 1st of each year, beginning on September 1, 2024.
The 2030 Notes are convertible into cash, shares of our common stock or a combination of cash and shares of our common stock, at our election, at an initial conversion price of approximately $21.74 per share, or 45.9939 shares per $1,000 principal amount of 2030 Notes, subject to adjustment upon the occurrence of certain events.
The Company has the option to redeem for cash the 2030 Notes, in whole or in part, beginning on March 5, 2027, if certain conditions are met as set forth in the indenture governing the 2030 Notes. The redemption price is equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest.
Capped Call Options: In March 2024, in connection with the offering of the 2030 Notes, we entered into privately negotiated capped call transactions (the “Capped Call Options”) with certain financial institutions (“Counterparties”). The Capped Call Options cover, subject to anti-dilution adjustments substantially similar to those in the 2030 Notes, 34.4 million shares of our common stock, the same number of shares that initially underlie the 2030 Notes issued in March 2024. The Capped Call Options have an expiration date of March 1, 2030, subject to earlier exercise.
The Capped Call Options are expected generally to reduce the potential dilution to our common stock upon conversion of the 2030 Notes and/or offset cash payments we are required to make in excess of the principal amount of the converted 2030 Notes, as the case may be, in the event that the market price per share of our common stock, as measured under the terms of the Capped Call Options, is greater than the strike price of the Capped Call Options, which initially corresponds to the initial conversion price of the 2030 Notes, or approximately $21.74 per share of common stock, with such reduction and/or offset subject to an initial cap of $31.06 per share of our common stock.
The Capped Call Options are separate transactions, entered into by the Company with each of the Counterparties, and are not part of the terms of the 2030 Notes. Holders of the 2030 Notes will not have any rights with respect to the Capped Call Options. We paid $65.3 million for the Capped Call Options in March 2024.
Equipment Notes: We have financing agreements for the purchase of certain equipment, including trucks and loaders. As of June 30, 2025, we had $26.2 million in principal (and accrued interest) outstanding under the equipment notes.
In December 2024, we entered into a secured uncommitted non-revolving credit facility (the “Uncommitted Credit Facility”) with Caterpillar Financial Services Corporation, providing an aggregate borrowing capacity of $25.0 million, which we may use only to finance agreed-upon equipment. During the six months ended June 30, 2025, we executed promissory notes under the Uncommitted Credit Facility to finance new equipment for use at Mountain Pass. As of June 30, 2025, we had no available borrowing capacity under the Uncommitted Credit Facility. The interest rates for the various borrowings approximated market rates at the time of borrowing and are fixed for the duration of the respective advances.
See Note 10, “Debt Obligations,” in the notes to the unaudited Condensed Consolidated Financial Statements for further information on our debt obligations.
Leases: We have lease arrangements for certain equipment and facilities, including office space, vehicles and equipment used in our operations. As of June 30, 2025, we had future expected lease payment obligations totaling $9.3 million, with $2.2 million due within the next 12 months. See Note 11, “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.
Share Repurchase Programs
In March 2024, our Board of Directors approved a share repurchase program (the “Program”) effective for one year under which the Company became authorized to repurchase up to an aggregate amount of $300.0 million of our outstanding common stock. In August 2024, our Board of Directors approved a $300.0 million increase to the Program, bringing the total authorized amount to $600.0 million. The Program was also extended and was effective until August 30, 2026. The authorization did not require the purchase of any minimum number of shares. On July 11, 2025, pursuant to the terms of the DoD Transaction Agreements, we terminated the Program. See the “Recent Developments” section for additional information.
Cash Flows
The following table summarizes our cash flows:
| For the six months ended June 30, | Change | ||||||||||||||||||||||||||||||||||||||||
| (in thousands, except percentages) | 2025 | 2024 | $ | % | |||||||||||||||||||||||||||||||||||||
| Net cash provided by (used in): | |||||||||||||||||||||||||||||||||||||||||

| Financing activities | $ | (7,734) | $ | 31,366 | $ | (39,100) | N/M |
N/M = Not meaningful.
Net Cash Used in Operating Activities: Net cash used in operating activities increased by $56.6 million for the six months ended June 30, 2025, as compared to the prior year period, driven primarily by the recognition of deferred revenue from sales of magnetic precursor products that began in the current year period and the increase in inventories to support the ramp of production of separated products and magnetic precursor products.
Net Cash Provided by Investing Activities: Net cash provided by investing activities increased by $43.0 million for the six months ended June 30, 2025, as compared to the prior year period, primarily driven by lower additions to property, plant and equipment for the six months ended June 30, 2025, which decreased by $51.0 million when compared to the prior year period, and related primarily to a decrease in construction spend on certain projects, such as the separations facility for heavy rare earth elements, as well as $12.2 million in proceeds from government awards used for construction that we received during the six months ended June 30, 2025. Additionally, we also received $9.7 million in the current year period in exchange for the sale of our 49% interest in VREX Holdco. This was partially offset by lower net proceeds from maturities of short-term investments in the current year period for a net decrease in cash provided of $21.7 million.
Net Cash Provided by (Used in) Financing Activities: Net cash used in financing activities was $7.7 million for the six months ended June 30, 2025, as compared to net cash provided by financing activities of $31.4 million in the prior year period. The change in cash flows from financing activities was driven by the net cash flow impact of $36.7 million from the issuance of the 2030 Notes, the payments of debt issuance costs associated with the 2030 Notes, the payments made to retire a significant portion of the 2026 Notes, the purchase of the Capped Call Options, and the payments made to repurchase our common stock, all of which occurred during the six months ended June 30, 2024.
Non-GAAP Financial Measures
We present Adjusted EBITDA, Adjusted Net Loss, Adjusted Diluted EPS, and Free Cash Flow, which are non-GAAP financial measures that we use to supplement our results presented in accordance with GAAP. These measures may be similar to measures reported by other companies in our industry and are regularly used by securities analysts and investors to measure companies’ financial performance. Adjusted EBITDA, Adjusted Net Loss, Adjusted Diluted EPS, and Free Cash Flow are not intended to be substitutes for any GAAP financial measures and, as calculated, may not be comparable to other similarly titled measures of performance or liquidity of other companies within our industry or in other industries.
Adjusted EBITDA
We define Adjusted EBITDA as our GAAP net income or loss before interest expense, net; income tax expense or benefit; and depreciation, depletion and amortization; further adjusted to eliminate the impact of stock-based compensation expense; initial start-up costs; transaction-related and other costs; accretion of asset retirement and environmental obligations; gain or loss on disposals of long-lived assets; gain or loss on early extinguishment of debt; other income or loss; and other items that we do not consider representative of our underlying operations. We present Adjusted EBITDA because it is used by management to evaluate our underlying operating and financial performance and trends. Adjusted EBITDA excludes certain expenses that are required in accordance with GAAP because they are non-recurring, non-cash or are not related to our underlying business performance. This non-GAAP financial measure is intended to supplement our GAAP results and should not be used as a substitute for financial measures presented in accordance with GAAP.
The following table presents a reconciliation of our Adjusted EBITDA, which is a non-GAAP financial measure, to our net income or loss, which is determined in accordance with GAAP:

(2)Included in “Start-up costs” within our unaudited Condensed Consolidated Statements of Operations and excludes any applicable stock-based compensation, which is included in the “Stock-based compensation expense” line above. Primarily relates to certain costs incurred in connection with the commissioning and starting up of our initial magnet-making capabilities at Independence prior to the achievement of commercial production. These costs include labor of incremental employees hired in advance to work directly on such commissioning activities, training costs, costs of testing and commissioning the new circuits and processes, and other related costs. Given the nature and scale of the related costs and activities, management does not view these as normal, recurring operating expenses, but rather as non-recurring investments to initially develop our magnet-making capabilities. Therefore, we believe it is useful and necessary for investors to understand our core operating performance in current and future periods by excluding the impact of these start-up costs. To the extent additional start-up costs are incurred in the future to expand our separations and magnet-making capabilities after initial achievement of commercial production (e.g., significantly expanding production capacity at an existing facility or building a new separations or magnet manufacturing facility), such costs would not be considered an adjustment for this non-GAAP financial measure.

For the three and six months ended June 30, 2025, amount is principally included in “Selling, general and administrative” within our unaudited Condensed Consolidated Statements of Operations. For the three and six months ended June 30, 2024, amount is principally included in “Advanced projects and development” within our unaudited Condensed Consolidated Statements of Operations.
(4)Included in “Other operating costs and expenses (income), net” within our unaudited Condensed Consolidated Statements of Operations.
Adjusted Net Loss and Adjusted Diluted EPS
We calculate Adjusted Net Loss as our GAAP net income or loss excluding the impact of stock-based compensation expense; initial start-up costs; transaction-related and other costs; gain or loss on disposals of long-lived assets; gain or loss on early extinguishment of debt; and other items that we do not consider representative of our underlying operations; adjusted to give effect to the income tax impact of such adjustments. We calculate Adjusted Diluted EPS as our GAAP diluted earnings or loss per share excluding the per share impact, using adjusted diluted weighted-average shares outstanding as the denominator, of stock-based compensation expense; initial start-up costs; transaction-related and other costs; gain or loss on disposals of long-lived assets; gain or loss on early extinguishment of debt; and other items that we do not consider representative of our
underlying operations; adjusted to give effect to the income tax impact of such adjustments. In addition, when appropriate, we include an adjustment to reverse the impact of applying the if-converted method to our 2026 Notes if necessary to reconcile between GAAP diluted earnings or loss per share and Adjusted Diluted EPS.
Adjusted Net Loss and Adjusted Diluted EPS exclude certain expenses that are required in accordance with GAAP because they are non-recurring, non-cash, or not related to our underlying business performance. To calculate the income tax impact of such adjustments on a year-to-date basis, we utilize an effective tax rate equal to our income tax expense or benefit excluding material discrete costs and benefits, with any impacts of changes in effective tax rate being recognized in the current period. We present Adjusted Net Loss and Adjusted Diluted EPS because it is used by management to evaluate our underlying operating and financial performance and trends. These non-GAAP financial measures are intended to supplement our GAAP results and should not be used as a substitute for financial measures presented in accordance with GAAP.
The following table presents a reconciliation of our Adjusted Net Loss, which is a non-GAAP financial measure, to our net income or loss, which is determined in accordance with GAAP:

(1)Tax impact of adjustments is calculated using an adjusted effective tax rate, which excludes the impact of discrete tax costs and benefits, to each adjustment. The adjusted effective tax rates were 25.4%, 23.7%, 24.7% and 30.1% for the three and six months ended June 30, 2025 and 2024, respectively.
(2)For the six months ended June 30, 2024, since the 2026 Notes were dilutive for purposes of computing GAAP diluted loss per share but antidilutive for purposes of computing Adjusted Diluted EPS, within this reconciliation, we have included this adjustment to reverse the impact of applying the if-converted method to the 2026 Notes in the computation of GAAP diluted loss per share.
(3)For the six months ended June 30, 2024, since the 2026 Notes were dilutive for purposes of computing GAAP diluted loss per share but antidilutive for purposes of computing Adjusted Diluted EPS, the adjusted diluted weighted-average shares outstanding excludes the potentially dilutive securities associated with the 2026 Notes.
Free Cash Flow
We calculate Free Cash Flow as net cash provided by or used in operating activities less additions to property, plant and equipment, net of proceeds from government awards used for construction. We believe Free Cash Flow is useful for comparing our ability to generate cash with that of our peers. The presentation of Free Cash Flow is not meant to be considered in isolation or as an alternative to cash flows from operating activities and does not necessarily indicate whether cash flows will be sufficient to fund cash needs.
The following table presents a reconciliation of our Free Cash Flow, which is a non-GAAP financial measure, to our net cash used in operating activities, which is determined in accordance with GAAP:
