## Exhibit 99.1

**Exhibit 99.1**

**Solaris Oilfield Infrastructure Announces Fourth Quarter and Full Year 2022 Results** 

**Summary Results and Highlights**

● Net income of $8.0 million, or $0.15 per diluted Class A share, for the quarter ended December 31, 2022; Adjusted pro forma net income of $10.2 million, or $0.22 per fully diluted share for the quarter ended December 31, 2022

● Adjusted EBITDA of $23.0 million for the quarter ended December 31, 2022

● Paid a regular quarterly dividend of $0.105 per share on December 16, 2022, Solaris' 17 <sup>th</sup> consecutive quarterly dividend; $112 million cumulatively returned to shareholders through dividends and share buybacks since 2018

● Increased deployments of Solaris' new top fill technology across multiple basins

● Revising previous 2023 capital expenditure guidance to range between $65 million and $75 million, reflecting an approximately 10% to 20% reduction year over year

HOUSTON, February 22, 2023 — (BUSINESS WIRE) — Solaris Oilfield Infrastructure, Inc. (NYSE:SOI) ("Solaris" or the "Company"), a leading provider of supply chain management and logistics solutions designed to drive efficiencies and reduce costs for the oil and natural gas industry, today reported financial results for the fourth quarter and full year 2022.

**Operational Update and Outlook**

During the fourth quarter of 2022, an average of 92 mobile proppant management systems were fully utilized, which was down 2% from average third quarter 2022 levels. Extreme weather events in December 2022 caused job startup delays which negatively impacted the fully utilized system count in the fourth quarter. Absent weather-related delays, the fully utilized system count would have been flat sequentially.

"I am very proud of the Solaris team's accomplishments in 2022, a year where we saw tremendous growth across our business. Our average fully utilized system count grew over 50% versus 2021, we rapidly rolled out our new top fill offering, expanded into new basins and onboarded over 200 new team members," Solaris' Chairman and Chief Executive Officer Bill Zartler commented. "We are experiencing continued growth in our business in 2023, including additional manufacturing and deployments of our new technology offerings to existing and new customers. These new technology deployments will drive both well site efficiency for our customers and earnings and cash flow growth for Solaris. As the pace of spending on new technology slows during 2023, we anticipate generating excess cash and will continue to prioritize shareholder returns. We look forward to engaging with our shareholders about potential uses of our future free cash flow."

**Fourth Quarter 2022 Financial Review**

Solaris reported net income of $8.0 million, or $0.15 per diluted Class A share, for fourth quarter 2022, compared to third quarter 2022 net income of $11.5 million, or $0.22 per diluted Class A share. Adjusted pro forma net income for fourth quarter 2022 was $10.2 million, or $0.22 per fully diluted share, compared to third quarter 2022 adjusted pro forma net income of $11.1 million, or $0.24 per fully diluted share. A description of adjusted pro forma net income and a reconciliation to net income attributable to Solaris, its most directly comparable generally accepted accounting principles ("GAAP") measure, and the computation of adjusted pro forma earnings per fully diluted share are provided below.

Revenues were $84.1 million for fourth quarter 2022, which were down 9% from third quarter 2022, driven by a seasonal decline in activity that was exacerbated by extreme cold weather-related job startup delays in December. The decrease in systems was partially offset by an increase in systems deployed with new technologies.

Adjusted EBITDA for fourth quarter 2022 was $23.0 million, which was down 4% from third quarter 2022. The decrease in Adjusted EBITDA was driven by a seasonal decline in activity that was exacerbated by extreme cold weather-related job startup delays in December. The decrease in systems was partially offset by an increase in systems deployed with new top fill solutions. Absent job startup delays and higher costs associated with the severe winter weather in December, the Company expects Adjusted EBITDA would have been approximately in line with third quarter levels. A description of Adjusted EBITDA and a reconciliation to net income, its most directly comparable GAAP measure, is provided below.

**Capital Expenditures, Free Cash Flow and Liquidity**

Capital expenditures in the fourth quarter 2022 were $21.9 million, which was above prior guidance of $15 million to $20 million due to advance orders for parts related to new top fills to be manufactured in 2023. The Company is revising its capital expenditure guidance for full year 2023 to a range of $65 million to $75 million, which accounts for improving operational efficiencies and flexibility to respond to

------

changing market dynamics while maintaining prior expectations for Solaris' top fill system growth. This compares to prior guidance of approximately $75 million. The Company's guidance for 2023 capital expenditures includes $15 million for maintenance capital which is unchanged from prior guidance.

Free cash flow (defined as net cash provided by operating activities less investment in property, plant and equipment) during fourth quarter 2022 was $2.2 million and reflects lower capital expenditures sequentially and a working capital source of $1.0 million as activity modestly slowed at year-end. Distributable cash flow (defined as Adjusted EBITDA less maintenance capital expenditures) was approximately $19 million for the fourth quarter 2022 and covered quarterly dividend distributions of approximately $4.9 million.

As of December 31, 2022, the Company had approximately $8.8 million of cash on the balance sheet. The Company had $8.0 million in borrowings outstanding on the credit facility, and total liquidity, including availability under the credit facility, was $50.8 million as of the end of the fourth quarter 2022.

**Shareholder Returns**

On November 17, 2022, the Company's Board of Directors declared a cash dividend of $0.105 per share of Class A common stock, which was paid on December 16, 2022 to holders of record as of December 6, 2022. A distribution of $0.105 per unit was also approved for holders of units in Solaris Oilfield Infrastructure, LLC ("Solaris LLC"). Since initiating the dividend in December 2018, the Company has paid 17 consecutive quarterly dividends. Cumulatively, the Company has returned approximately $112 million in cash to shareholders through dividends and share repurchases since December 2018.

**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.
