On September 11, 2024, closed the acquisition of Mobile Energy Rentals LLC ("MER," and such acquisition, the "MER Acquisition"), a premier provider of distributed power solutions; established new Solaris Power Solutions segment
Closed $325 million senior secured term loan to effectuate the MER Acquisition and to support continued growth capital investment into the Solaris Power Solutions fleet
Executed additional power service agreements with customers, totaling approximately 450 megawatts ("MW") of generation capacity, or greater than 80% of expected 2025 ending capacity (including all deliveries on order); contract tenor ranges from two to four years, providing the Company significant earnings visibility
Returned a total of $5 million to shareholders in third quarter 2024 through dividends, resulting in $183 million cumulatively returned to shareholders since 2018
Approved fourth quarter 2024 dividend of $0.12 per share on October 30, 2024, to be paid on December 16, 2024, to holders of record as of December 6, 2024 which, once paid, will represent Solaris' 25^th consecutive dividend

"During the quarter, Solaris both announced and closed on a transformative acquisition, while continuing to deliver strong service quality for our customers across both business segments," Chairman and Chief Executive Officer Bill Zartler commented.

"The commercial opportunity set for our Power Solutions segment is accelerating rapidly, further highlighting the demand for ‘behind-the-meter' power generation applications across a variety of end markets. We are pleased to announce that since closing the acquisition we have signed several power service contracts at tenors ranging from two to four years, bringing our customer agreements to over 80% of our expected ending 2025 capacity. This is a testament to both the strong team we have in place, as well as the broad-based growth in electrification and artificial intelligence computing applications.

"Our Solaris Logistics Solutions segment continues to focus on technology advancements that drive efficiency gains and add value for our customers, which is evident in our leading market position within the Logistics Solutions segment and the continued adoption of our new technologies. We remain committed to the provision of exceptional service quality by leveraging our company culture and innovative technologies across both of our business segments. Together, the combined business provides a balanced and attractive financial profile that is also uniquely positioned to grow and drive total shareholder value."

Third Quarter 2024 Financial Review

Net loss of $2 million and ($0.04) per diluted Class A share, for third quarter 2024, compared to second quarter 2024 net income of $10 million and $0.20 per diluted Class A share, and third quarter 2023 net income of $8 million and $0.16 per diluted Class A share. Adjusted pro forma net income⁽¹⁾ for third quarter 2024 was $4 million, or $0.08 per fully diluted share, compared to second quarter 2024 adjusted pro forma net income of $6 million, or $0.13 per fully diluted share, and third quarter 2023 adjusted pro forma net income of $9 million, or $0.19 per fully diluted share.

Revenue was $75 million for the third quarter 2024, which was up 2% from second quarter 2024 and up 8% from third quarter 2023. Adjusted EBITDA⁽¹⁾ for third quarter 2024 was $22 million, which was up 7% from second quarter 2024 and down 5% from third quarter 2023. The increase was primarily due to the impact of the MER Acquisition, which contributed 20 days of results to the third quarter following the transaction close on September 11, 2024.

In conjunction with the MER Acquisition, the Company established a new Solaris Power Solutions segment to manage and report on the newly acquired business. The legacy business will be managed and reported on as Solaris Logistics Solutions.

Solaris Logistics Solutions

Revenue of $70 million, down 5% sequentially from second quarter ended June 30, 2024
Segment Adjusted EBITDA⁽¹⁾⁽²⁾ of $24 million, down 6% sequentially from second quarter ended June 30, 2024
91 fully utilized systems, down 1% sequentially from second quarter ended June 30, 2024

The sequential decrease in revenue was driven by a decrease in last mile trucking contribution and a slight decrease in fully utilized systems. Adjusted EBITDA contribution was down in line with revenue.

Solaris Power Solutions

Revenue of approximately $5 million in its first 20 days
Segment Adjusted EBITDA⁽¹⁾⁽²⁾ of $3 million in its first 20 days

Financial results for Solaris Power Solutions during the 20 days ended September 30, 2024 primarily reflect contribution from the data center industry. The Company has since signed agreements for expansion and extension with its largest customer, as well as new agreements with several new customers. The new agreements have contract tenors ranging from two to four years and total approximately 450 MW out of the approximately 535 MW the Company expects to own after all equipment on order is received by the end of third quarter 2025.

Shareholder Returns

A previously announced cash dividend of $0.12 per share of Class A common stock was paid on September 6, 2024 to holders of record as of August 23, 2024, and a distribution of $0.12 per unit was paid to holders of units in Solaris Energy Infrastructure, LLC ("Solaris LLC," and such holders "Solaris LLC Unitholders"), subject to the same payment and record date, totaling approximately $5 million.

On October 30, 2024, Solaris' Board of Directors approved a fourth quarter 2024 cash dividend of $0.12 per share of Class A common stock, to be paid on December 16, 2024 to holders of record as of December 6, 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 $7 million in aggregate.

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

Pro forma for the announced fourth quarter 2024 dividend, Solaris has returned approximately $190 million to shareholders through dividends and share repurchases.

Cash Flow, Capital Expenditures, and Liquidity

Net cash from operating activities was $11 million in the third quarter of 2024 and free cash flow⁽¹⁾ after asset disposals was negative $47 million in the third quarter of 2024, including a working capital use of $7 million.

Capital expenditures in the third quarter of 2024 were approximately $58 million, which primarily consisted of progress payments for power equipment on order.

In connection with the MER Acquisition, Solaris entered into a senior secured term loan agreement for $325 million and, on October 2, 2024, established a new $75 million revolving credit facility, subject to a borrowing base calculation. The Company expects to fund the remaining planned capital expenditures to grow the Solaris Power Solutions segment using proceeds from these financing transactions, along with operating cash flow.

As of September 30, 2024, Solaris had $325 million in outstanding borrowings and $117 million in total cash, of which $98 million was restricted for growth capital expenditures.

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.

SOLARIS ENERGY INFRASTRUCTURE, INC SEGMENT REPORTING (In thousands) (Unaudited) Prior to the MER Acquisition, we operated in a single segment which reflected how our business was managed and the nature of our services. Following the acquisition, we re-evaluated our reportable segments and now report two distinct business segments. These segments offer different services and align with how our chief operating decision maker assesses operating performance and allocates resources. Our reporting segments are: 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 including field technician support, software solutions, and may also include last mile and mobilization services. Solaris Power Solutions – provides configurable sets of natural gas-powered mobile turbines and ancillary equipment. This segment primarily leases equipment to data center and energy customers and is focused on continuing to grow its services with these customers as well as across multiple commercial and industrial end-markets. We evaluate the performance of our business segments based on Adjusted EBITDA. We define Adjusted EBITDA as our net income before depreciation and amortization expense, interest expense, net, income tax expense, stock-based compensation, loss on debt extinguishment, 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.

SOLARIS ENERGY INFRASTRUCTURE, INC 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.

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 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.
