“We had a very challenging quarter, operationally and financially, with higher-than-expected upstream downtime and a continued weak pricing environment. Despite this, we more than doubled NdPr production sequentially. We also signed a substantial new NdPr supply agreement with a global automaker,” said James Litinsky, Founder, Chairman and CEO of MP Materials. “Going forward, we expect to ramp NdPr output by 50% in the third quarter, positioning us for continued reductions in our refined products cost structure through year-end.”

Litinsky continued, “While it is early, we are cautiously optimistic that the third quarter will be one of our best REO production quarters ever. Moreover, our growth projects are progressing well with Upstream 60K advancing and NdPr metal production in Fort Worth on track to begin later this year.”

Revenue decreased 51% year-over-year to $31.3 million, driven by a 43% decrease in rare earth oxide (“REO”) in concentrate sales volumes and a 33% decrease in the realized price of REO, partially offset by sales of separated NdPr, which began in the fourth quarter of 2023. The decrease in REO sales volume was mainly due to lower REO production volumes and the start-up of separated rare earth (“Stage II”) production, as a significant portion of the REO produced, which could otherwise have been sold as rare earth concentrate, was used for work-in-process or to produce packaged and finished separated rare earth products. The change in realized price reflects a continued softer pricing environment for rare earth products as compared to the prior year period. REO production volumes decreased 16% year-over-year primarily due to higher unplanned downtime due to equipment damage to one of our thickeners which impacted production for approximately three weeks.

Adjusted EBITDA declined $54.0 million to $(27.1) million, driven mainly by the lower revenue as discussed above, as well as higher cost of sales and general and administrative expense. The increase in cost of sales was mostly driven by production costs related to the start of Stage II production, including an inventory reserve of $11.8 million recorded in the quarter. The reserve was largely attributable to elevated carrying costs of the initial production of separated products given the early stage of ramping the Stage II facilities to normalized production levels. In addition, cost of sales was impacted by repair and maintenance costs associated with the thickener equipment damage. Selling, general, and administrative expenses were also impacted by higher legal costs as well as the initial costs related to the implementation of a new ERP system in the quarter, some of which were non-cash.

Adjusted Net Income (Loss) decreased $45.1 million to $(28.0) million, mainly due to the lower Adjusted EBITDA as well as higher depreciation expense resulting from an increase in capital assets placed into service over the last year. Also impacting the comparison was higher interest expense, mainly due to the newly issued 2030 convertible notes, as well as slightly lower interest income. These changes were partially offset by an income tax benefit due to a pre-tax loss in the current quarter compared to income tax expense due to the company generating pre-tax income in the prior-year quarter.

Net income (loss) decreased $41.5 million year-over-year to $(34.1) million, primarily due to the factors driving the lower Adjusted Net Income (Loss) discussed above, partially offset by lower demolition, start-up and transaction costs in the current quarter.

Diluted earnings per share (“EPS”) decreased $0.25 year-over-year to a diluted loss per share of $(0.21), in line with the change in net income (loss) discussed above. Adjusted Diluted EPS decreased $0.26 to $(0.17) in line with the decrease in Adjusted Net Income (Loss) discussed above. Diluted EPS and Adjusted Diluted EPS were also impacted by a lower average share count in the current quarter. Diluted share count was primarily lower due to the repurchase of 13.0 million shares in March of 2024. Adjusted Diluted share count was impacted by both the share repurchase as well as approximately 15.6 million shares associated with 2026 convertible notes included in the 2023 average share count due to their dilutive effect in that period.

(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. 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 Fort Worth 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.

(2)	For the six months ended June 30, 2024, since the 2026 Notes were dilutive for purposes of computing GAAP diluted earnings (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 earnings (loss) per share.
(3)	For the six months ended June 30, 2024, since the 2026 Notes were dilutive for purposes of computing GAAP diluted earnings (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. For the three months ended June 30, 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; and other income or loss. 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, 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 3.00% unsecured senior convertible notes due March 2030.

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.

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 Company’s mining and processing capacity and efficiency.

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 Company’s separations and finishing capacity and efficiency.

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 we recognize revenue on its sale, whether sold as NdPr oxide or NdPr metal, as determined in accordance with GAAP. For NdPr metal sales, the MTs sold and included in NdPr Sales Volume are calculated on the basis of the volume of NdPr oxide used to produce such NdPr metal. 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. 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.

NdPr Realized Price per kilogram (“KG”) for a given period is calculated as the quotient of: (i) our 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.
