Commenced shipments and ramping production of NdPr oxide

Announces “Upstream 60K” strategy targeting ~50% expansion of REO output at Mountain Pass

Stage I REO sales and production volumes of 9,177 and 10,766 metric tons, respectively

Revenue of $52.5M and net loss of $4.3M

Adjusted EBITDA of $15.6M

Diluted loss per share of $0.02 and Adjusted Diluted EPS of $0.04

MP Materials Corp. (NYSE: MP) (“MP Materials” or the “Company”), today announced financial results for the three months ended September 30, 2023.

“In the third quarter, we produced separated NdPr on U.S. soil, repatriating a critical national security capability. This is a tremendous milestone for the company and American supply chain independence writ large,” said James Litinsky, Founder, Chairman and CEO of MP Materials. “Our financial results reflect solid operational performance against a weak pricing backdrop. In addition, we are excited to announce “Upstream 60K” where we will target a 50% increase in REO production within four years with modest incremental investment. In addition, we have begun trial production of NdPr metal and continue to make steady progress in our magnetics business, both technically and commercially.”

(1)		The vast majority of the Company’s revenue pertains to sales of its rare earth concentrate product.
(2)		See “Use of Non-GAAP Financial Measures” below for the definitions of Adjusted EBITDA, Adjusted Net Income, Adjusted Diluted EPS and Production Costs, which is used in the calculation of Production Cost per REO MT. See tables below for reconciliations of non-GAAP financial measures to their most directly comparable GAAP financial measures.
(3)		During the third quarter of 2023, upon production of separated products, management identified two new metrics as KPIs of the Company’s business. See “Key Performance Indicators” below for definitions and further information.

Revenue decreased 58% year-over-year, driven by a 51% decrease in the realized price of rare earth oxide (“REO”) in concentrate as well as a 14% decrease in sales volumes. The change in realized price reflects a significantly softer pricing environment for rare earth products as compared to the prior year period. The decrease in REO sales volume was due to the start-up of separated rare earth (Stage II) production, as a sizeable portion of the REO produced, which could otherwise have been sold as rare earth concentrate, was used to charge the Stage II circuits, establish separations work-in-process inventory, or produce packaged and finished separated rare earth products. REO production volumes were relatively unchanged year-over-year.

Adjusted EBITDA decreased 83% year-over-year, driven by lower per-unit profitability, and higher personnel and other general and administrative costs, as well as advanced projects and development costs. The per-unit profitability decrease was driven primarily by the decline in realized prices discussed above, as well as higher production costs, partially offset by lower shipping costs. Production cost of $2,020 per MT of REO increased 22% year-over-year, mainly due to higher payroll costs, primarily as a result of increased headcount as we expand our workforce and ready our facilities to support Stage II production, and to a lesser extent, higher material and supply costs.

Adjusted Net Income decreased by 90% year-over-year to $7.0 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. These declines were partially offset by increased interest and investment income earned on an increase in short-term investments as well as lower income tax expense primarily associated with the lower pre-tax income.

Net income decreased $67.5 million year-over-year to a net loss of $4.3 million, primarily due to the factors driving the lower Adjusted Net Income discussed above, as well as costs incurred to support growth initiatives, start-up costs, and costs associated with the removal of legacy facilities at Mountain Pass. These impacts were partially offset by lower stock-based compensation expense compared to the prior year period, mainly due to the timing of grants and the accelerated method of recognizing expense for virtually all of our stock awards.

Diluted earnings per share (“EPS”) decreased $0.35 year-over-year to a diluted loss per share of $0.02, in line with the change in net income discussed above. Adjusted Diluted EPS decreased $0.32 to $0.04 in line with the decrease in Adjusted Net Income discussed above.

(1)		Principally included in “Selling, general and administrative” within our unaudited Condensed Consolidated Statements of Operations.
(2)		Relates to certain costs included in “Advanced projects, start-up, development and other” within our unaudited Condensed Consolidated Statements of Operations that do not qualify for capitalization incurred in connection with the initial commissioning and starting up of our separations capability at Mountain Pass and our metal alloy and magnet-making capabilities at Fort Worth prior to the achievement of commercial production. These costs include payroll of employees directly involved in such commissioning activities, training costs, costs of testing and commissioning the new circuits and processes, and other related costs. Given the nature and scale of the related costs and activities, management does not view these as normal, recurring operating expenses, but rather as non-recurring investments to develop such capabilities. Therefore, we believe it is useful and necessary for investors to understand our core operating performance in current and future periods by excluding the impact of these start-up costs.

Use of Non-GAAP Financial Measures

This press release references certain non-GAAP financial measures, including Adjusted EBITDA, Adjusted Net Income, Adjusted Diluted EPS, and Production Costs, 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; start-up costs; transaction-related and other non-recurring costs; accretion of asset retirement and environmental obligations; gain or loss on disposals of long-lived assets; and other income or loss. MP Materials defines Adjusted Net Income as GAAP net income or loss excluding the impact of stock-based compensation expense; start-up costs; transaction-related and other non-recurring costs; gain or loss on disposals of long-lived assets; 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; and the release of valuation allowance. MP Materials defines Adjusted Diluted EPS as GAAP diluted earnings or loss per share (“EPS”) excluding the per share impact, using adjusted diluted weighted-average shares outstanding, of stock-based compensation expense; start-up costs; transaction-related and other non-recurring costs; gain or loss on disposals of long-lived assets; 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; and the release of valuation allowance. Production Costs, which we use to calculate our KPI, Production Cost per REO MT (see “Key Performance Indicators” below), is defined as GAAP cost of sales (excluding depreciation, depletion and amortization), less stock-based compensation expense included in cost of sales, shipping and freight costs, and costs not attributable to concentrate sales, for a given period.

MP Materials’ management uses Adjusted EBITDA, Adjusted Net Income, 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, 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, and Adjusted Diluted EPS provide an additional tool for investors to use in evaluating projected operating results and trends. Furthermore, MP Materials believes Production Cost per REO MT sold, which utilizes the non-GAAP financial measure, Production Costs, is a key indicator of the Company’s concentrate production efficiency. 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 NdPr product, the latter of which is also included in our KPI, NdPr Production Volume. REO Production Volume is a key indicator of the Company’s mining and concentrate processing capacity and efficiency.

REO Sales Volume for a given period is calculated in MTs. A unit, or MT, is considered sold for 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.

Realized Price per REO MT for a given period is calculated as the quotient of: (i) the Company’s rare earth concentrate sales, which is 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.

Production Cost per REO MT is calculated as the quotient of: (i) the Company’s Production Costs (see “Use of Non-GAAP Financial Measures” above) for a given period and (ii) the Company’s REO Sales Volume for the same period. Production Cost per REO MT a key indicator of the Company’s concentrate production efficiency.

As MP Materials continues to evolve as a business and transitions from a producer of rare earth concentrate to a producer of separated rare earth products upon completing the commissioning of the Company’s Stage II project, the metrics that management anticipates using to evaluate the business may change or be revised. For example, in completing the transition to separated rare earth products, management may determine that Production Cost per REO MT, which is a metric focused solely on Stage I concentrate operations, and consequently, Production Costs, are no longer meaningful in evaluating and understanding the Company’s business or operating results.

NdPr Production Volume 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 separating and finishing capacity and efficiency.

Our NdPr Sales Volume for a given period is calculated in MTs and on an NdPr oxide-equivalent basis (see example 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. For example, assuming a material conversion ratio of 1.25, a sale of 100 MTs of NdPr metal would be included in this KPI as 125 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 expect to have a mix of contracts with customers where we will 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.
