• Adjusted EBITDA* of $21 million

• Generated $19 million of cash flow from operations and $18 million in free cash flow*

• Returned a total of $5 million to shareholders in second quarter 2024 through dividends, resulting in $178 million cumulatively returned to shareholders since 2018

• Announced third quarter 2024 dividend of $0.12 per share on July 29, 2024, to be paid on September 6, 2024, which, once paid, will represent Solaris’ 24^th consecutive dividend

• Announced entry into definitive agreement on July 9, 2024 to acquire Mobile Energy Rentals LLC (“MER”), a premier provider of distributed power solutions, for an initial purchase price of approximately $200 million, consisting of $60 million of cash and the issuance of approximately 16.5 million shares of the Company’s Class B common stock at a price per share of $8.50; proposed transaction remains subject to shareholder approval, receipt of regulatory approvals, and other customary closing conditions and is expected to close in the third quarter of 2024

HOUSTON, Texas, August 8, 2024 — (BUSINESS WIRE) — Solaris Oilfield Infrastructure, Inc. (NYSE:SOI) (“Solaris” or the “Company”), today announced second quarter 2024 financial and operational results.

“Solaris delivered another quarter of strong free cash flow as we continue to generate cash from our core sand handling equipment business and the organic additional fleet investments we made over the last few years,” Chairman and Chief Executive Officer Bill Zartler commented.

“The MER acquisition will provide Solaris an exciting opportunity to diversify into the growing distributed power market, which will provide an additional business line that we expect to deliver continued strong shareholder returns from a new earnings base with access to new end markets, including oil and gas production, midstream and downstream, as well as various commercial and industrial applications. We remain on track to close this transaction in the third quarter 2024.”

Shareholder Returns

A previously announced cash dividend of $0.12 per share of Class A common stock was paid on June 17, 2024 to holders of record as of June 7, 2024, and a distribution of $0.12 per unit was paid to holders of units in Solaris Oilfield Infrastructure, LLC (“Solaris LLC,” and such holders “Solaris LLC Unitholders”), subject to the same payment and record date, totaling approximately $5 million.

On July 25, 2024, Solaris’ Board of Directors approved a third quarter 2024 cash dividend of $0.12 per share of Class A common stock, to be paid on September 6, 2024 to holders of record as of August 23, 2024, and a distribution of $0.12 per unit to Solaris LLC Unitholders, which is subject to the same payment and record dates, or approximately $5 million in aggregate.

Solaris did not repurchase shares during the second quarter of 2024. Approximately $15 million remains in the current share repurchase authorization.

Pro forma for the announced third quarter 2024 dividend, Solaris has returned approximately $183 million to shareholders through dividends and share repurchases.

Cash Flow, Capital Expenditures and Liquidity

Net cash from operating activities was $19 million in the second quarter of 2024 and free cash flow* after asset disposals was positive $18 million in the second quarter of 2024, including a working capital use of $4 million.

Capital expenditures in the second quarter of 2024 were approximately $1 million.

As of June 30, 2024, Solaris had $5 million of cash on the balance sheet. Solaris ended the second quarter of 2024 with $16 million in borrowings outstanding and $53 million of liquidity. Net debt* (defined as total debt outstanding less cash) at the end of the second quarter of 2024 was $11 million.

Second Quarter 2024 Financial Review

Net income was $10 million and $0.20 per diluted Class A share, for second quarter 2024, compared to first quarter 2024 net income of $7 million and $0.14 per diluted Class A share, and second quarter 2023 net income of $12 million and $0.24 per diluted Class A share. Adjusted pro forma net income* for second quarter 2024 was $6 million, or $0.13 per fully diluted share, compared to first quarter 2024 adjusted pro forma net income of $7 million, or $0.16 per fully diluted share, and second quarter 2023 adjusted pro forma net income of $11 million, or $0.25 per fully diluted share.

Revenue was $74 million for second quarter 2024, which was up 9% from first quarter 2024 and down 4% from second quarter 2023. Adjusted EBITDA* for second quarter 2024 was $21 million, which was down 8% from first quarter 2024 and down 22% from second quarter 2023. The sequential increase in revenue was driven by an increase in lower-margin ancillary last mile logistics services activity. On an Adjusted EBITDA basis, this was more than offset by a sequential decline in fully utilized systems, resulting in a sequential decrease in Adjusted EBITDA. The decreases in revenue and Adjusted EBITDA from the second quarter 2023 were primarily due to a decrease in fully utilized systems.

During the second quarter of 2024, Solaris earned revenue on 92 fully utilized systems, which includes sand systems and top fill systems. Total fully utilized systems were down 10% from first quarter 2024 and down 15% from second quarter 2023. Solaris followed an average of 56 industry frac crews on a fully utilized basis in the second quarter of 2024, compared to 64 industry frac crews in the first quarter of 2024.

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, Net debt, Free cash flow, 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.

RECONCILIATION AND CALCULATION OF NON-GAAP FINANCIAL AND OPERATIONAL MEASURES

(In thousands)

(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 alternative 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.

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 LLC not held by Solaris Oilfield 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.
