Forward-Looking Statements This presentation contains “forward-looking statements” of Atlas Energy Solutions Inc. (“Atlas,” the “Company,” “AESI,” “we,” “us” or “our”) within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Statements that are predictive or prospective in nature, that depend upon or refer to future events or conditions or that include the words “may,” “assume,” “forecast,” “position,” “strategy,” “potential,” “continue,” “could,” “will,” “plan,” “project,” “budget,” “predict,” “pursue,” “target,” “seek,” “objective,” “believe,” “expect,” “anticipate,” “intend,” “estimate,” and other expressions that are predictions of or indicate future events and trends and that do not relate to historical matters identify forward-looking statements. Our forward-looking statements include statements about our business strategy, industry, future operations and profitability, expected capital expenditures and the impact of such expenditures on our performance, financial position, production, revenues and losses, our capital programs, management changes, current and potential future long-term contracts and our future business and financial performance. Although forward-looking statements reflect our good faith beliefs at the time they are made, we caution you that these forward-looking statements are subject to a number of risks and uncertainties, most of which are difficult to predict and many of which are beyond our control. These risks include, but are not limited to, commodity price volatility stemming from the continued impacts of COVID-19, including any new strains or variants, the ongoing war in Ukraine, adverse developments affecting the financial services industry, our ability to complete growth projects, including the Dune Express, on time and on budget, actions of OPEC+ to set and maintain oil production levels, the level of production of crude oil, natural gas and other hydrocarbons and the resultant market prices of crude oil, inflation, environmental risks, operating risks, regulatory changes, lack of demand, market share growth, the uncertainty inherent in projecting future rates of reserves, production, cash flow, access to capital, the timing of development expenditures and other factors discussed under the heading “Risk Factors” in our Registration Statement on Form S-1 filed with the U.S. Securities and Exchange Commission (“SEC”) on January 31, 2023 (as later amended) in connection with our initial public offering (our “IPO”) or any of our other filings with the SEC. You are cautioned not to place undue reliance on any forward-looking statements, which speak only as of the date of this presentation. Should one or more of these risks or uncertainties occur, or should underlying assumptions prove incorrect, our actual results and plans could differ materially from those expressed in any forward-looking statements. All forward-looking statements, expressed or implied, are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that we or persons acting on our behalf may issue. Except as otherwise required by applicable law, we disclaim any duty and do not intend to update any forward-looking statements to reflect events or circumstances after the date of this presentation. Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Free Cash Flow, Adjusted Free Cash Flow Margin Adjusted Free Cash Flow Conversion and Maintenance Capital Expenditures are non-GAAP supplemental financial measures are used by our management and by external users of our financial statements such as investors, research analysts and others, in the case of Adjusted EBITDA, to assess our operating performance on a consistent basis across periods by removing the effects of development activities, provide views on capital resources available to organically fund growth projects and, in the case of Adjusted Free Cash Flow, to assess the financial performance of our assets and their ability to sustain dividends over the long term without regard to financing methods, capital structure, levels of reinvestment or historical cost basis. These measures do not represent and should not be considered alternatives to, or more meaningful than, net income, income from operations, net cash provided by operating activities or any other measure of financial performance presented in accordance with GAAP as measures of our financial performance. Adjusted EBITDA and Adjusted Free Cash Flow have important limitations as analytical tools because they exclude some but not all items that affect net income, the most directly comparable GAAP financial measure. Our computation of Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Free Cash Flow, Adjusted Free Cash Flow Margin, Adjusted Free Cash Flow Conversion and Maintenance Capital Expenditures may differ from computations of similarly titled measures of other companies. We define Adjusted EBITDA as net income (loss) before depreciation, depletion and accretion, interest expense, income tax expense, stock and unit-based compensation, gain (loss) on extinguishment of debt and unrealized commodity derivative gain (loss).We define Adjusted EBITDA Margin as Adjusted EBITDA divided by total sales. We define Adjusted Free Cash Flow as Adjusted EBITDA less Maintenance Capital Expenditures. We define Maintenance Capital Expenditures as capital expenditures less growth capital expenditures. We define Adjusted Free Cash Flow Margin as Adjusted Free Cash Flow divided by total sales. We define Adjusted Free Cash Flow Conversion as Adjusted Free Cash Flow divided by Adjusted EBITDA. Reserves This Presentation includes frac sand reserve and resource estimates based on engineering, economic and geological data assembled and analyzed by our mining engineers, which are reviewed periodically by outside firms. However, frac sand reserve estimates are by nature imprecise and depend to some extent on statistical inferences drawn from available drilling data, which may prove unreliable. There are numerous uncertainties inherent in estimating quantities and qualities of frac sand reserves and non-reserve frac sand deposits and costs to mine recoverable reserves, many of which are beyond our control and any of which could cause actual results to differ materially from our expectations. These uncertainties include: geological and mining conditions that may not be fully identified by available data or that may differ from experience; assumptions regarding the effectiveness of our mining, quality control and training programs; assumptions concerning future prices of frac sand, operating costs, mining technology improvements, development costs and reclamation costs; and assumptions concerning future effects of regulation, including the issuance of required permits and taxes by governmental agencies. Trademarks and Trade Names The Company owns or has rights to various trademarks, service marks and trade names that it uses in connection with the operation of its business. This presentation also contains trademarks, service marks and trade names of third parties, which are the property of their respective owners.
