Solaris Energy Infrastructure solaris-energy.com Disclaimer Forward-Looking Statements This presentation contains forward-looking statements 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. Examples of forward- looking statements include, but are not limited to, our business strategy, our industry, our future profitability, changes in tariffs, trade barriers, price and exchange controls and other regulatory requirements, and the impact of such policies on us, our customers and the global economic environment, the success of Stateline and associated transactions and its impact on the financial condition and results of operations of our Solaris Power Solutions segment, our acquisition of Omega Foundation Services (Omega”) and our ability to realize the anticipated benefits, cost savings and growth opportunities of that acquisition, our ability to successfully integrate Omega’s operations, personnel and capabilities and to retain its key employees and customer relationships, the expected impact of the Omega acquisition on our financial condition and results of operations, the anticipated growth of our power fleet and sources of financing thereafter, the volatility in global oil markets, expected capital expenditures and the impact of such expenditures on performance, management changes, current and potential future long-term contracts, our future business and financial performance and our results of operations, and the other risks discussed in Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2025 filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 27, 2026, Part II, Item 1A. “Risk Factors” in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2026 filed with the SEC on May 1, 2026 and Part II, Item 1A. “Risk Factors” in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2026 filed with the SEC on August 6, 2026. Forward-looking statements are based on our current expectations and assumptions regarding our business, the economy and other future conditions. Because forward-looking statements relate to the future, by their nature, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. As a result, our actual results may differ materially from those contemplated by the forward-looking statements. Factors that could cause our actual results to differ materially from the results contemplated by such forward-looking statements include, but are not limited to, the factors discussed or referenced in our filings made from time to time with the SEC. Readers are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date hereof. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them. We undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law. About Non-GAAP Measures In addition to financial results determined in accordance with generally accepted accounting principles in the United States (“GAAP”), this presentation presents non-GAAP financial measures. Management believes that Adjusted EBITDA provides useful information to investors regarding our financial condition and results of operations because it helps facilitate analysis of operating performance. In particular, we view Adjusted EBITDA as an important indicator of performance. We define EBITDA as net income, plus (i) depreciation and amortization expense, (ii) interest expense and (iii) income tax expense. We define Adjusted EBITDA as EBI TDA plus (i) stock-based compensation expense and (ii) certain non-cash items and extraordinary, unusual or non-recurring gains, losses or expenses. Adjusted EBITDA attributable to Solaris excludes the 49.9% non-controlling interest share of Stateline JV's Adjusted EBITDA attributable to our partner in the Stateline JV. Although management believes the aforementioned non-GAAP financial measures are good tools for internal use and the investment community in evaluating our overall financial performance, the foregoing non-GAAP financial measures should not be considered as a substitute for or superior to other measures of financial performance prepared in accordance with GAAP. However, no reconciliations of these non-GAAP measure to their most directly comparable GAAP measures are available without unreasonable efforts. This is due to the inherent difficulty of forecasting the timing or amount of various reconciling items that would impact the most directly comparable forward-looking GAAP financial measures, that have not yet occurred, are out of our control and/or cannot be reasonably predicted given we have not completed any reporting processes for the periods presented. Pro Forma Information Certain information in this presentation is shown on a pro forma basis as if our recent acquisitions, including Omega, had been completed at the beginning of the earliest period presented. This pro forma information is presented for illustrative purposes only, is shown on a relative basis without presentation of amounts, is based on Company estimates and assumptions, has not been prepared in accordance with Article 11 of Regulation S-X and has not been audited or reviewed by our independent registered public accounting firm. It is not necessarily indicative of the results of operations that would have been achieved had the acquisitions been completed on the dates assumed, nor is it indicative of our future results of operations or financial condition. 5
