All forward-looking statements, expressed or implied, are expressly qualified in their entirety by this cautionary statement.

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. 2 Disclaimer

Some data is also based on our good faith estimates, which are derived from our review of internal sources as well as the third-party sources described above.

Non-GAAP Financial Measures Adjusted EBITDA, Adjusted EBITDA Margin, Net Debt, and Net Leverage are non-GAAP supplemental financial measures 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. 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 has important limitations as an analytical tool because it exclude some but not all items that affect net income, the most directly comparable GAAP financial measure. Our computation of Adjusted EBITDA and Adjusted EBITDA Margin may differ from computations of similarly titled measures of other companies. Non-GAAP Measure Definitions: We define Adjusted EBITDA as net income before depreciation, depletion and accretion, interest expense, income tax expense, stock and unit-based compensation, loss on extinguishment of debt, unrealized commodity derivative gain (loss), and non-recurring transaction costs. Management believes Adjusted EBITDA is useful because it allows management to more effectively evaluate the Company’s operating performance and compare the results of its operations from period to period and against our peers without regard to financing method or capital structure. We exclude the items listed above from net income in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. We define Adjusted EBITDA Margin as Adjusted EBITDA divided by total sales. We define Net Debt as total debt, net of discount and deferred financing costs, plus right-of-use lease liabilities, less cash and cash equivalents. We define Net Leverage as Net Leverage divided by Adjusted EBITDA. Because Atlas provides these Non-GAAP measures on a forward-looking basis, it cannot reliably or reasonably predict certain of the necessary components of the most directly comparable forward-looking GAAP financial measures. Accordingly, Atlas is unable to present a quantitative reconciliation of such forward-looking, non-GAAP financial measures to the respective most directly comparable forward-looking GAAP financial measures. 3 Disclaimer (cont’d)
