MP MATERIALS 2#3Use of Non-GAAP Financial Measures This presentation references certain non-GAAP financial measures, including Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Diluted EPS, Total Value Realized, Production Costs, Free Cash Flow, Normalized Stage I Free Cash Flow, and Adjusted Operating Cash Flow, which have not been prepared in accordance with generally accepted accounting principles in the United States ("GAAP"). We define Adjusted EBITDA as our GAAP net income before interest expense, net; income tax expense or benefit; and depreciation, depletion and amortization; further adjusted to eliminate the impact of stock- based compensation expense; transaction-related, start-up and other non-recurring costs; accretion of asset retirement and environmental obligations; gain or loss on sale or disposal of long-lived assets; tariff rebates; and other income or loss, net. We define Adjusted EBITDA Margin as our Adjusted EBITDA divided by our total revenue adjusted for the impact of tariff rebates related to prior period sales. Adjusted Net Income is defined as our GAAP net income excluding the impact of depletion; stock-based compensation expense; transaction-related, start-up and other non-recurring costs; gain or loss on sale or disposal of long-lived assets; tariff rebates; and other income or loss, net; adjusted to give effect to the income tax impact of such adjustments. Adjusted Diluted EPS is defined as GAAP diluted earnings per share ("EPS") excluding the per share impact, using GAAP diluted weighted-average shares outstanding as the denominator, of depletion; stock-based compensation expense; transaction-related, start-up and other non- recurring costs; gain or loss on sale or disposal of long-lived assets; tariff rebates; and other income or loss, net; adjusted to give effect to the income tax impact of such adjustments. Total Value Realized, which we use to calculate realized price per REO MT, is defined as our product sales adjusted for the revenue impact of tariff rebates related to prior period sales. Realized price per REO MT is calculated as the quotient of: (i) our Total Value Realized for a given period and (ii) our REO sales volume for the same period. Production Costs, which we use to calculate production cost per REO MT, is defined as our cost of sales (excluding depreciation, depletion and amortization), less stock-based compensation expense included in cost of sales, shipping and freight costs, and costs attributable to certain other sales, for a given period. Production cost per REO MT is calculated as the quotient of: (i) our Production Costs for a given period and (ii) our REO sales volume for the same period. We define Free Cash Flow as net cash provided by operating activities less additions of property, plant and equipment, net of proceeds received from government awards used for construction. Normalized Stage I Free Cash Flow is defined as Free Cash Flow plus (i) the non-cash portion of revenue from sales to Shenghe (i.e., Offtake Paydown), (ii) growth capital expenditures, and (iii) expenditures for transaction-related, start-up and other non-recurring costs. We define Adjusted Operating Cash Flow as net cash provided by operating activities plus the non-cash portion of revenue from sales to Shenghe. You can find the reconciliation of these measures to the most directly comparable GAAP measures in the Appendix. MP Materials' management uses Adjusted EBITDA, Adjusted EBITDA Margin, 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 EBITDA Margin, 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 believes that the use of Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, and Adjusted Diluted EPS provide an additional tool for investors to use in evaluating projected operating results and trends. MP Materials believes realized price per REO MT, which utilizes the non-GAAP financial measure, Total Value Realized, is an important measure of the market price of the Company's product. 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 production efficiency. We believe Free Cash Flow, Normalized Stage I Free Cash Flow, and Adjusted Operating Cash Flow, are useful for comparing our ability to generate cash with that of our peers. 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. 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.
