Fourth Quarter 2024 Consolidated Review

Revenue increased 48% year-over-year to $61.0 million, driven by higher sales in the Materials Segment primarily driven by higher NdPr oxide and metal sales due to the transition to midstream production of separated products.

Adjusted EBITDA declined by $12.0 million year-over-year to $(10.7) million, driven primarily by elevated production costs in the Materials Segment mainly due to the initial ramp of production of separated products.

Adjusted Net Loss increased by $14.9 million year-over-year to $(18.9) million, driven mainly by the lower Adjusted EBITDA discussed above, as well as higher interest expense from the new 2030 convertible notes (“2030 Notes”) issued in the first quarter of 2024, lower interest income, and higher depreciation expense from additional midstream and downstream capital assets placed into service over the last year. These changes were partially offset by a larger tax benefit due to a higher pre-tax loss.

Net loss increased by $6.1 million year-over-year to $(22.3) million, primarily due to the factors driving the change in Adjusted Net Loss discussed above, partially offset by a $6.6 million gain associated with the early extinguishment of a portion of convertible notes due in 2026 (“2026 Notes”) in the current quarter, as well as lower start-up costs and advanced projects and development expenses in the current quarter.

Diluted earnings per share (“EPS”) and Adjusted Diluted EPS decreased by $0.05 and $0.10 year-over-year, respectively, to $(0.14) and $(0.12), respectively, in line with the change in net loss and Adjusted Net Loss discussed above. Diluted EPS and Adjusted Diluted EPS were also impacted by a lower average share count in the current quarter, driven primarily by the repurchase of 15.2 million shares in 2024.

Full Year 2024 Consolidated Review

Revenue decreased 20% to $203.9 million compared to 2023 primarily as a result of lower Realized Price per REO metric ton (“MTs”), as well as lower REO Sales Volume in the Materials Segment as production of separated products ramped.

Adjusted EBITDA declined $152.7 million year-over-year to $(50.2) million, driven primarily by elevated production costs mainly due to the initial ramp of production of separated products, as well as lower realized prices in the Materials Segment in 2024.

Adjusted Net Income (Loss) decreased by $145.5 million year-over-year to $(74.1) million, driven mainly by the change in Adjusted EBITDA discussed above as well as higher depreciation expense from additional midstream and downstream capital assets placed into service in 2023 and 2024, increased interest expense from the new 2030 Notes and lower interest income. These changes were partially offset by a tax benefit due to a pre-tax loss in 2024 compared to tax expense on pre-tax income in 2023.

Net income (loss) decreased by $89.7 million year-over-year to $(65.4) million, driven by the factors impacting the decrease in Adjusted Net Income (Loss) discussed above, partially offset by a $52.9 million pre-tax gain on the early extinguishment of debt, as well as lower start-up costs from the beginning of midstream production, both in 2024.

Diluted EPS and Adjusted Diluted EPS decreased by $0.71 and $0.83, respectively, compared to 2023, to diluted EPS of $(0.57) and Adjusted Diluted EPS $(0.44), in line with the change in net income (loss) and Adjusted Net Income (Loss) discussed above. Diluted EPS was also impacted by the dilutive effect of the 2026 Notes repurchased in March of 2024. Diluted EPS and Adjusted Diluted EPS were also impacted by a lower average share count in 2024, driven primarily by the repurchase of 15.2 million shares in 2024.

Fourth Quarter 2024 Materials Segment Review

Materials Segment revenue increased 48% to $61.0 million year-over-year, driven by a $23.0 million increase in NdPr oxide and metal sales due to the transition to production of midstream products, primarily NdPr oxide, which began in the fourth quarter of 2023. The increase in revenue was aided by a 9% increase in REO Sales Volume driven in part by higher upstream production volumes, partially offset by a 16% decrease in the Realized Price per REO MT due to a continued soft pricing environment for rare earth products.

Materials Segment Adjusted EBITDA declined $10.5 million to $(1.3) million year-over-year, driven mainly by higher Materials Segment cost of sales (“Segment COS”) due to elevated production costs associated with separated rare earth products production ramp toward normalized capacity. Segment COS was also impacted by a $6.4 million write-down of certain separated product inventories, primarily related to Lanthanum production, which was more than offset by an $8.4 million credit from the Section 45X Tax Credit in the quarter, which benefited from a favorable final rule making by the IRS in October.

Full Year 2024 Materials Segment Review

Materials Segment revenue decreased 20% to $203.9 million year-over-year, driven by a 36% decline in Realized Price per REO MT and an 11% decline in REO MTs sold in the year, partially offset by a $57.1 million increase in NdPr oxide and metal sales in 2024. The decline in realized price reflected the softer pricing environment for rare earth products in the year. The decline in REO MTs sold and the increase in NdPr oxide and metal sales was primarily due to the ramp-up in midstream operations, as a significantly higher portion of REO produced was not sold as concentrate but instead refined and sold as NdPr oxide and metal during 2024.

Materials Segment Adjusted EBITDA declined $144.5 million to $(14.1) million year-over-year, driven mainly by higher Materials Segment COS due to higher production costs associated with the increased sales volumes of NdPr oxide in 2024 from the continued ramp in separated product production. Segment COS was also impacted by a $21.5 million write-down of certain of our separated product inventories and higher property taxes, partially offset by a $12.2 million credit from the Section 45X Tax Credit during the year.

Fourth Quarter and Full Year 2024 Magnetics Segment Review

Magnetics Segment Adjusted EBITDA for the quarter and year declined $0.7 million and $5.7 million, respectively, primarily due to higher segment selling, general and administrative expenses, driven by higher personnel costs associated with increased headcount to support the Independence facility, as well as increases in research and development and property taxes.

(1)		Principally included in “Selling, general and administrative” within our unaudited Consolidated Statements of Operations.
(2)		Included in “Start-up costs” within our unaudited Consolidated Statements of Operations and excludes any applicable stock-based compensation, which is included in the “Stock-based compensation expense” line above. Relates to certain costs incurred in connection with the commissioning and starting up of our initial separations capability at Mountain Pass and our initial magnet-making capabilities at the Independence Facility 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 separations and 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.

(1)		Principally included in “Selling, general and administrative” within our unaudited Consolidated Statements of Operations.
(2)		Included in “Start-up costs” within our unaudited Consolidated Statements of Operations and excludes any applicable stock-based compensation, which is included in the “Stock-based compensation expense” line above. Relates to certain costs incurred in connection with the commissioning and starting up of our initial separations capability at Mountain Pass and our initial magnet-making capabilities at the Independence Facility 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 separations and 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.
(3)		Pertains to legal, consulting, and advisory services, and other costs associated with specific transactions, including potential acquisitions, mergers, or other investments. Amounts for the three months and year ended December 31, 2024, are principally included in “Selling, general and administrative” within our unaudited Consolidated Statements of Operations. Amounts for the three months and year ended December 31, 2023, are principally included in “Advanced projects and development” within our unaudited Consolidated Statements of Operations.
(4)		Included in “Other operating costs and expenses” within our unaudited Consolidated Statements of Operations.
(5)		Amounts are the result of the Company adjusting its estimated cash flows and timing for its existing environmental obligation during the fourth quarter of 2024.
(6)		The year ended December 31, 2023, included $5.5 million in demolition costs associated with demolishing and removing certain out-of-use older facilities and infrastructure from the Mountain Pass site to accommodate future expansion in rare earth processing.
(7)		Amount for the three months ended December 31, 2024, pertains to a gain recognized on the debt exchange in December 2024 whereby the Company exchanged a portion of its 2026 Notes for new 2030 Notes. The year ended December 31, 2024, amount also includes a gain recognized on the retirement of 2026 Notes in March 2024 in connection with the issuance of 2030 Notes.
(8)		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 20.1%, 31.3%, 23.7% and 25.9%, for the three months and years ended December 31, 2024 and 2023, respectively.

(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 20.1%, 31.3%, 23.7% and 25.9%, for the three months and years ended December 31, 2024 and 2023, respectively.
(2)		For the year ended December 31, 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 year ended December 31, 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 exclude the potentially dilutive securities associated with the 2026 Notes.
(4)		For the year ended December 31, 2023, the 2026 Notes were antidilutive for GAAP purposes. For purposes of calculating Adjusted Diluted EPS, we have added back the assumed conversion of the 2026 Notes since they would not be antidilutive when using Adjusted Net Income (Loss) as the numerator in the calculation of Adjusted Diluted EPS.

Use of Non-GAAP Financial Measures

This press release references certain non-GAAP financial measures, including Adjusted EBITDA, Adjusted Net Income (Loss), and Adjusted Diluted EPS, which have not been prepared in accordance with GAAP. MP Materials defines Adjusted EBITDA as 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 management does not consider representative of our underlying operations. MP Materials defines Adjusted Net Income (Loss) as 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 management does not consider representative of our underlying operations; adjusted to give effect to the income tax impact of such adjustments. MP Materials defines Adjusted Diluted EPS as 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 management does 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. When applicable, adjusted diluted weighted-average shares outstanding reflect the anti-dilutive impact of our capped call options entered into in connection with the issuance of our 2030 Notes.

MP Materials’ management uses Adjusted EBITDA, Adjusted Net Income (Loss), and Adjusted Diluted EPS to compare MP Materials’ performance to that of prior periods for trend analyses and for budgeting and planning purposes. MP Materials believes Adjusted EBITDA, Adjusted Net Income (Loss), and Adjusted Diluted EPS provide useful information to management and investors regarding certain financial and business trends relating to MP Materials’ financial condition and results of operations. MP Materials’ management believes that the use of Adjusted EBITDA, Adjusted Net Income (Loss), and Adjusted Diluted EPS provides an additional tool for investors to use in evaluating projected operating results and trends. MP Materials’ method of determining these non-GAAP measures may be different from other companies’ methods and, therefore, may not be comparable to those used by other companies and MP Materials does not recommend the sole use of these non-GAAP measures to assess its financial performance. Management does not consider non-GAAP measures in isolation or as an alternative or to be superior to financial measures determined in accordance with GAAP. The principal limitation of non-GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in MP Materials’ financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non-GAAP financial measures. In order to compensate for these limitations, management presents reconciliations of such non-GAAP financial measures to the most directly comparable GAAP financial measures.

Segment Information

During the fourth quarter of 2024, the Company modified its segment structure largely as a result of initial production of magnetic precursor products. Accordingly, beginning with the fourth quarter of 2024, the Company’s reportable segments, which are primarily based on the Company’s internal organizational structure and types of products, are its two operating segments—Materials and Magnetics. In conjunction with this change, prior period amounts have been recast to conform to this new segment reporting structure.

The Materials segment operates the Mountain Pass Rare Earth Mine and Processing Facility located near Mountain Pass, San Bernardino County, California, which produces refined rare earth products as well as rare earth concentrate and related products. The Magnetics segment operates a rare earth metal, alloy and magnet manufacturing facility in Fort Worth, Texas (“Independence”), where the Company began production of magnetic precursor products in December 2024 and anticipates manufacturing NdFeB permanent magnets by the end of 2025.

Segment Adjusted EBITDA is management’s primary segment measure of profit or loss required by GAAP in assessing segment performance and deciding how to allocate the Company’s resources. Segment Adjusted EBITDA is calculated as segment revenues less significant segment expenses, specifically, cost of sales (excluding depreciation, depletion and amortization and stock-based compensation expense) and selling, general and administrative expenses (excluding stock-based compensation expense), as well as certain other operating expenses (referred to as “other segment items”). Significant segment expenses and other segment items also exclude certain costs that are non-recurring, non-cash or are not related to the segments’ underlying business performance.

Key Performance Indicators

REO Production Volume is measured in MTs, the Company’s principal unit of sale for its 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 the Company’s upstream operations.

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 GAAP. REO Sales Volume is a key measure of the Company’s ability to convert its concentrate production into revenue. REO Sales Volume includes both traditional concentrate as well as roasted concentrate.

Realized Price per REO MT for a given period is calculated as the quotient of: (i) the Company’s rare earth concentrate sales, which are determined in accordance with GAAP, for a given period and (ii) the Company’s REO Sales Volume for the same period. Realized Price per REO MT is an important measure of the market price of the Company’s concentrate product.

NdPr Production Volume for a given period is measured in MTs, the Company’s principal unit of sale for its 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 the Company’s midstream operations.

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 on the basis of 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.

NdPr Realized Price per kilogram (“KG”) for a given period is calculated 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.
