About Non-GAAP Measures

In addition to financial results determined in accordance with generally accepted accounting principles in the United States (“GAAP”), this news release presents non-GAAP financial measures. Management believes that EBITDA, Adjusted EBITDA, Adjusted pro forma net income and Adjusted pro forma earnings per fully diluted share provide useful information to investors regarding the Company’s financial condition and results of operations because they reflect the core operating results of our businesses and help facilitate comparisons of operating performance across periods. Although management believes the aforementioned non-GAAP financial measures are good tools for internal use and the investment community in evaluating Solaris’ overall financial performance, the foregoing non-GAAP financial measures should be considered in addition to, not as a substitute for or superior to, other measures of financial performance prepared in accordance with GAAP. A reconciliation of these non-GAAP measures to the most directly comparable GAAP measures is included in the accompanying financial tables.

SEGMENT REPORTING

(In thousands)

(Unaudited)

We report two distinct business segments, which offer different services and align with how our chief operating decision makers assesses operating performance and allocates resources.

Our reporting segments are:

• Solaris Power Solutions – delivers power generation and distribution solutions. The segment’s offerings support data center, energy, and other commercial and industrial sector customers by providing flexible, on-demand power infrastructure.

• Solaris Logistics Solutions – designs and manufactures specialized equipment that enables the efficient management of raw materials used in the completion of oil and natural gas wells. Solaris’ equipment-based logistics services include field technician support, software solutions, and may also include last mile and mobilization services.

We evaluate the performance of our business segments based on Adjusted EBITDA. We define Adjusted EBITDA as our net income plus depreciation and amortization expense, interest expense, income tax expense, stock-based compensation expense, and certain non-cash items and any extraordinary, unusual or non-recurring gains, losses or expenses.

Summarized financial information by business segment is shown below. The financial information by business segment for prior periods has been restated to reflect the changes in reportable segments.

RECONCILIATION AND CALCULATION OF NON-GAAP FINANCIAL AND OPERATIONAL MEASURES

(In thousands, except per share data)

(Unaudited)

EBITDA AND ADJUSTED EBITDA

We view EBITDA and Adjusted EBITDA as important indicators of performance. We use them to assess our results of operations because it allows us, our investors and our lenders to compare our operating performance on a consistent basis across periods by removing the effects of varying levels of interest expense due to our capital structure, depreciation and amortization due to our asset base and other items that impact the comparability of financial results from period to period. We present EBITDA and Adjusted EBITDA because we believe they provide useful information regarding trends and other factors affecting our business in addition to measures calculated under generally accepted accounting principles in the United States (“GAAP”).

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 EBITDA plus (i) stock-based compensation expense and (ii) certain non-cash items and extraordinary, unusual or non-recurring gains, losses or expenses.

EBITDA and Adjusted EBITDA should not be considered in isolation or as substitutes for an analysis of our results of operation and financial condition as reported in accordance with GAAP. Net income is the GAAP measure most directly comparable to EBITDA and Adjusted EBITDA. EBITDA and Adjusted EBITDA should not be considered alternatives to net income presented in accordance with GAAP. Because EBITDA and Adjusted EBITDA may be defined differently by other companies in our industry, our definitions of EBITDA and Adjusted EBITDA may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

The following table presents a reconciliation of the GAAP financial measure of net income to the non-GAAP financial measure of Adjusted EBITDA.

CASH AND DEBT ATTRIBUTABLE TO SOLARIS

ADJUSTED PRO FORMA NET INCOME AND ADJUSTED PRO FORMA EARNINGS PER FULLY DILUTED SHARE

Adjusted pro forma net income represents net income attributable to Solaris assuming the full exchange of all outstanding membership interests in Solaris Energy Infrastructure, LLC (“Solaris LLC”) not held by Solaris Energy Infrastructure, Inc. for shares of Class A common stock, adjusted for certain non-recurring items that the Company doesn't believe directly reflect its core operations and may not be indicative of ongoing business operations. Adjusted pro forma earnings per fully diluted share is calculated by dividing adjusted pro forma net income by the weighted-average shares of Class A common stock outstanding, assuming the full exchange of all outstanding units of Solaris LLC (“Solaris LLC Units”), after giving effect to the dilutive effect of outstanding equity-based awards.

When used in conjunction with GAAP financial measures, adjusted pro forma net income and adjusted pro forma earnings per fully diluted share are supplemental measures of operating performance that the Company believes are useful measures to evaluate performance period over period and relative to its competitors. By assuming the full exchange of all outstanding Solaris LLC Units, the Company believes these measures facilitate comparisons with other companies that have different organizational and tax structures, as well as comparisons period over period because it eliminates the effect of any changes in net income attributable to Solaris as a result of increases in its ownership of Solaris LLC, which are unrelated to the Company's operating performance, and excludes items that are non-recurring or may not be indicative of ongoing operating performance.

Adjusted pro forma net income and adjusted pro forma earnings per fully diluted share are not necessarily comparable to similarly titled measures used by other companies due to different methods of calculation. Presentation of adjusted pro forma net income and adjusted pro forma earnings per fully diluted share should not be considered alternatives to net income and earnings per share, as determined under GAAP. While these measures are useful in evaluating the Company's performance, it does not account for the earnings attributable to the non-controlling interest holders and therefore does not provide a complete understanding of the net income attributable to Solaris. Adjusted pro forma net income and adjusted pro forma earnings per fully diluted share should be evaluated in conjunction with GAAP financial results. A reconciliation of adjusted pro forma net income to net income attributable to Solaris, the most directly comparable GAAP measure, and the computation of adjusted pro forma earnings per fully diluted share are set forth below.
