Forward-Looking Statements

The information in this presentation includes “forward-looking statements.” All statements, other than statements of historical fact included in this presentation, regarding our strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. When used in this presentation, the words “could,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on Solaris’ current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events. When considering forward-looking statements, you should keep in mind the risk factors and other cautionary statements described under the heading “Risk Factors” included in Solaris’ final prospectus dated May 11, 2017, filed in connection with its initial public offering pursuant to Rule 424(b) under the Securities Act of 1933, as amended, with the Securities and Exchange Commission on May 15, 2017. We caution you that these forward-looking statements are subject to all of the risks and uncertainties, most of which are difficult to predict and many of which are beyond our control, incident to the transportation, storage and delivery of proppant. These risks include, but are not limited to, the level of domestic capital spending by the oil and natural gas industry, natural or man-made disasters and other external events that may disrupt our manufacturing operations, volatility of oil and natural gas prices, changes in general economic and geopolitical conditions, large or multiple customer defaults including defaults resulting from actual or potential insolvencies, technological advancements in well service technologies, competitive conditions in our industry and our ability to fully protect our intellectual property rights. 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.

You are cautioned not to place undue reliance on any forward-looking statements, which speak only as of the date of this presentation. Except as otherwise required by applicable law, we disclaim any duty to update and do not intend to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this presentation.

This presentation includes financial measures that are not presented in accordance with generally accepted accounting principles ("GAAP"), including EBITDA and Adjusted EBITDA. While management believes such measures are useful for investors, they do not have any standardized meaning and are therefore unlikely to be comparable to similar measures presented by other companies. The presentation of non-GAAP financial measures should not be used as a replacement for, and should not be considered in isolation from, financial measures that are in accordance with GAAP. Please see the Appendix for reconciliations of those measures to comparable GAAP measures.
