Exhibit 99.1

Solaris Oilfield Infrastructure Announces First Quarter 2023 Results

First Quarter 2023 Summary Results and Highlights

● Net income of $11.9 million, or $0.23 per diluted Class A share; Adjusted pro forma net income of $11.0 million, or $0.24 per fully diluted share

● Adjusted EBITDA of $25.1 million, reflecting a 9% sequential and 60% year-over-year increase

● Increased deployments of Solaris’ new top fill technology and AutoBlend™ units across multiple basins

● Raised regular quarterly dividend by 5% to $0.11 per share, which was paid on March 24, 2023 and represented Solaris’ 18^th consecutive quarterly dividend

● Repurchased 1.6 million Class A common stock shares (3.5% of total outstanding shares) during the quarter; approximately $36 million remains available under $50 million share repurchase authorization announced in the first quarter

● $131 million cumulatively returned to shareholders through dividends and share buybacks since 2018

HOUSTON, May 1, 2023 — (BUSINESS WIRE) — Solaris Oilfield Infrastructure, Inc. (NYSE:SOI) (“Solaris” or the “Company”), today announced first quarter 2023 results, with revenues of $82.7 million, net income of $11.9 million, adjusted pro forma net income of $11.0 million, or $0.24 per fully diluted share and Adjusted EBITDA of $25.1 million.

“Solaris continued to execute on our strategy in the first quarter. We grew earnings sequentially and increased deployments of our new product offerings, including top fill and AutoBlend™ systems,” Solaris’ Chairman and Chief Executive Officer Bill Zartler commented.

“Our field execution and new technology deployments are lowering our customers’ costs and driving well site efficiency. We expect continued adoption of our new technology deployments to offset potential natural gas driven activity softness in the second quarter, which should result in Adjusted EBITDA and earnings that are flat sequentially.

“We also recently outlined an enhanced shareholder capital return program, where at least 50% of free cash flow will be returned to shareholders. We took the first step in executing on this framework through a 5% increase in our quarterly dividend and the authorization of a $50 million share buyback program. During the first quarter we retired 3.5% of our total outstanding shares and we expect to continue executing on our buyback program in the second quarter.”

First Quarter 2023 Financial Review

Solaris reported net income of $11.9 million, or $0.23 per diluted Class A share, for first quarter 2023, compared to fourth quarter 2022 net income of $8.0 million, or $0.15 per diluted Class A share, and first quarter 2022 net income of $5.7 million, or $0.11 per diluted Class A share. Adjusted pro forma net income for first quarter 2023 was $11.0 million, or $0.24 per fully diluted share, compared to fourth quarter 2022 adjusted pro forma net income of $10.2 million, or $0.22 per fully diluted share, and first quarter 2022 adjusted pro forma net income of $4.8 million, or $0.11 per fully diluted share.

Revenues were $82.7 million for first quarter 2023, which were down 2% sequentially and up 45% year over year. First quarter revenue was positively impacted by pricing improvements over fourth quarter, as well as the addition of top fill systems, and offset by a decline in lower margin ancillary trucking services. Adjusted EBITDA for first quarter 2023 was $25.1 million, which was up 9% from fourth quarter 2022 and up 60% from first quarter 2022. The sequential increase in Adjusted EBITDA was driven by pricing improvement and additional top fill systems as noted above, as well as a 23% increase in fully utilized mobile proppant management systems when compared to Adjusted EBITDA for first quarter 2022.

During the first quarter of 2023, an average of 92 mobile proppant management systems were fully utilized, which was in line with average fourth quarter 2022 levels. During the first quarter, 25% of our systems utilized a Solaris top fill system compared to 16% in the fourth quarter of 2022 and 1% in the first quarter of 2022.

Capital Expenditures, Free Cash Flow and Liquidity

Capital expenditures in the first quarter 2023 were approximately $19 million, which is primarily related to manufacturing of top fill systems. Solaris is maintaining its capital expenditure guidance for full year 2023 of $65 million to $75 million, which includes $15 million for maintenance capital. We continue to expect capital expenditures to be weighted towards the first half of 2023.

Free cash flow (defined as net cash provided by operating activities less investment in property, plant and equipment) during first quarter 2023 was negative $2 million, including a seasonally-higher working capital use of $8 million and capital expenditures of $19 million. Distributable cash flow (defined as Adjusted EBITDA less maintenance capital expenditures) was approximately $22 million for the first quarter 2023, which was up approximately 15% sequentially and nearly 60% year over year, and covered quarterly dividend distributions of approximately $5 million.

As of March 31, 2023, the Company had approximately $2 million of cash on the balance sheet. The Company had $26 million in borrowings outstanding on the credit facility. In April 2023, Solaris amended and expanded its credit facility by $25 million, which results in pro forma liquidity of $51 million as of the end of first quarter 2023.

Shareholder Returns

On March 2, 2023, the Company’s Board of Directors approved an enhanced shareholder return program, which included a $50 million share repurchase authorization and a 5% increase in the Company’s cash dividend to $0.11 per share of Class A common stock, which was paid on March 24, 2023 to holders of record as of March 14, 2023. A distribution of $0.11 per unit was also approved for holders of units in Solaris Oilfield Infrastructure, LLC (“Solaris LLC”).

During the first quarter of 2023, the Company repurchased 1.6 million Class A common stock shares, or 3.5% of the Company’s total outstanding shares, for approximately $14 million at an average price of $8.80 per share, leaving approximately $36 million in the Company’s stock repurchase authorization.

Since initiating the dividend in December 2018, the Company has paid 18 consecutive quarterly dividends and repurchased approximately 9% of total outstanding shares. Cumulatively, the Company has returned approximately $131 million in cash to shareholders through dividends and share repurchases since December 2018.

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 adjusted net income, adjusted diluted earnings per share and Adjusted EBITDA, 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 define EBITDA as net income, plus (i) depreciation and amortization expense, (ii) interest expense and (iii) income tax expense, including franchise taxes. 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.

We believe that our presentation of EBITDA and Adjusted EBITDA provides useful information to investors in assessing our financial condition and results of operations. 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 net income to EBITDA and Adjusted EBITDA for each of the periods indicated.

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.
