This Quarterly Report on Form 10-Q (the “Quarterly Report”) includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Statements that are predictive in nature, that depend upon or refer to future events or conditions or that include the words “believe,” “expect,” “anticipate,” “intend,” “estimate” and other expressions that are predictions of or indicate future events and trends and that do not relate to historical matters identify forward-looking statements. Our forward-looking statements include statements about our business strategy, our industry, our future profitability, expected capital expenditures and the impact of such expenditures on our performance, management changes, current and potential future long-term contracts and our future business and financial performance. In addition, our forward-looking statements address the various risks and uncertainties associated with the extraordinary market environment and impacts resulting from both the coronavirus 2019 (“COVID-19”) pandemic and the continued volatility in global oil markets, and the expected impact of these events on our businesses, operations, earnings and results.

A forward-looking statement may include a statement of the assumptions or bases underlying the forward-looking statement. We believe that we have chosen these assumptions or bases in good faith and that they are reasonable. You are cautioned not to place undue reliance on any forward-looking statements. You should also understand that it is not possible to predict or identify all such factors and should not consider the following list to be a complete statement of all potential risks and uncertainties. Factors that could cause our actual results to differ materially from the results contemplated by such forward-looking statements include:

●

the level of domestic capital spending and access to capital markets by the oil and natural gas industry and uncertainty regarding the future actions of oil producers, including the members of the Organization of the Petroleum Exporting Countries and ~~the risk that they take actions that will prolong or exacerbate the current over-supply of crude oil;~~Russia;

●

developments and uncertainty in the global economy ~~as well as the public health crisis related to the COVID-19 pandemic,~~ and the resulting impacts to the demand and supply for crude oil and natural gas or volatility of oil and natural gas ~~prices;~~

●

~~operational challenges relating to the COVID-19 pandemic, distribution and administration of the COVID-19 vaccines and efforts to mitigate the impact and spread of the virus;~~

●

~~uncertainty regarding the sustainability and extent of a continued economic recovery in the United States and elsewhere, which in turn will likely affect demand for crude oil~~prices, and therefore the demand for the ~~services~~service we provide and the commercial opportunities available to us;

●

geopolitical risks, including the war in Ukraine, which could affect the stability and continued recovery of oil and gas markets;

●

consolidation amongst current or potential customers that could affect demand for our products and services;

●

inflationary risks and supply chain constraints, including changes in market price and availability of materials;

●

significant changes in the transportation industries or fluctuations in transportation costs or the availability or reliability of transportation that service our business;

●

large or multiple customer defaults, including defaults resulting from actual or potential insolvencies;

●

technological advancements in well completion technologies and our ability to expand our product and service offerings;

●

competitive conditions in our industry;

●

inability to fully protect our intellectual property rights;

●

actions taken by our customers, competitors and third-party operators;

●

changes in the availability and cost of capital;

~~Table of Contents~~

●

our ability to successfully implement our business strategy;

Table of Contents

●

changes in our tax status;

●

the effects of existing and future laws, ~~and~~rulings, governmental regulations and accounting standards and statements (or the interpretation thereof) on us and our customers;

●

cyber-attacks targeting systems and infrastructure used by the oil and natural gas industry;

●

the effects of future litigation;

●

credit markets;

natural or man-made disasters and other external events that may disrupt our manufacturing operations;

●

uncertainty regarding our future operating results;

●

~~the impact of current and future laws, rulings, governmental regulations, accounting standards and statements, and related interpretations;~~ and

●

plans, objectives, expectations and intentions contained in this Quarterly Report that are not historical.

All forward-looking statements speak only as of the date of this Quarterly Report. You should not place undue reliance on our forward-looking statements. Although forward-looking statements reflect our good faith beliefs at the time they are made, forward-looking statements involve known and unknown risks, uncertainties and other factors, including the factors described under Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, ~~2020,~~2021, this Quarterly Report and in our other filings with the United States Securities and Exchange Commission (the “SEC”), which may cause our actual results, performance or achievements to differ materially from anticipated future results, performance or achievements expressed or implied by such forward-looking statements. We undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events, changed circumstances or otherwise, unless required by law.

Notes to the Condensed Consolidated Financial Statements
(Dollars in millions, except share data)

1. Organization and Background of Business

Description of Business

2. Summary of Significant Accounting Policies

Basis of Presentation and Consolidation

Solaris Oilfield Infrastructure, Inc. (either individually or together with its subsidiaries, as the context requires “Solaris Inc.” or the “Company”) is the managing member of Solaris Oilfield Infrastructure, LLC (“Solaris LLC”) and is responsible for all operational, management and administrative decisions relating to Solaris LLC’s business. Solaris Inc. consolidates the financial results of Solaris LLC and its subsidiaries and reports non-controlling interest related to the portion of the units in Solaris LLC (the “Solaris LLC Units”) not owned by Solaris Inc., which will reduce net income attributable to the holders of Solaris Inc.’s Class A common stock.

The accompanying interim unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). These financial statements reflect all normal recurring adjustments that are necessary for fair presentation. Operating results for the three and ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020~~2021 are not necessarily indicative of the results that may be expected for the full year or for any interim period.

The unaudited interim condensed consolidated financial statements do not include all information or notes required by GAAP for annual financial statements and should be read together with Solaris Inc.’s Annual Report on Form 10-K for the year ended December 31, ~~2020~~2021 and notes thereto.

All material intercompany transactions and balances have been eliminated upon consolidation.

~~COVID-19 and~~ Global Economic, Geopolitical and Market Conditions

The ~~strain~~recent volatility in global markets driven by continued inflation, geopolitical factors and the uncertainty of ~~coronavirus ("COVID-19") has caused,~~a potential global economic slowdown have the potential to disrupt the supply and ~~continues to cause, severe disruptions to the U.S. and global economies, including the~~demand for oil and natural gas ~~industry and~~across the ~~demand for our products and services.~~

globe. The degree to which ~~COVID-19~~these and ~~related~~other events outside of our control adversely ~~impacts~~impact our results will depend on future developments, which are highly uncertain, ~~and~~ cannot be predicted ~~including the~~and are outside of our control. The timing, extent, trajectory and duration of ~~the COVID-19 pandemic, the emergence of new strains or variants of COVID-19, the continued development, availability and administration of effective treatments and vaccines~~their impacts upon our business and the industry in which we, our customers and vendors operate could impact ~~of the COVID-19 pandemic on the global economy and~~ any subsequent recovery of normal economic and operating conditions.

Use of Estimates

The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Table of Contents

The most significant estimates relate to ~~taxes,~~ stock-based compensation, useful lives and salvage values of long-lived assets, future cash flows associated with goodwill and long-lived asset impairment, net realizable value of inventory, income taxes, Tax Receivable Agreement liability, collectability of accounts receivable and estimates of allowance for credit losses and determination of the present value of lease payments and right-of-use assets.

Revenue Recognition

The Company recognizes revenue in accordance with ASC Topic 606, Revenues from Contracts with Customers (“ASC Topic 606”). Under ASC Topic 606, revenue recognition is based on the transfer of control, or the customer’sability to benefit from our services and products in an amount that reflects the consideration expected to be received in exchange for those services and products.

The majority of our contracts contain multiple performance obligations, such as work orders containing a combination of equipment, last mile logistics services, and labor services. We allocate the transaction price to each performance obligation identified in the contract based on relative stand-alone selling prices, or estimates of such prices, and recognize the related revenue as control of each individual product or service is transferred to the customer, in satisfaction of the corresponding performance obligations. We measure progress using an input method based on resources consumed or expended relative to the total resources expected to be consumed or expended. We assess our customers’ ability and intention to pay, which is based on a variety of factors including historical payment experience and financial condition and we typically charge our customers on a weekly or monthly basis. Contracts with customers are typically on thirty- to sixty-day payment terms.

Disaggregation of Revenue

The following table summarizes revenues from our contracts disaggregated by revenue generating activity contained therein for the three and six months ended June 30, 2022 and 2021:


	Three Months Ended June 30,				Six Months Ended June 30,
	2022		2021		2022		2021

Wellsite services	$	86.5	$	34.9	$	143.1	$	63.3
Transloading and Other		0.2		0.2		0.5		0.6
Total revenue	$	86.7	$	35.2	$	143.6	$	63.8

Recently Issued Accounting Standards

In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2020-04, Reference Rate Reform, which provides temporary optional guidance to companies impacted by the transition away from the London Interbank Offered Rate (“LIBOR”). The guidance provides certain expedients and exceptions to applying GAAP in order to lessen the potential accounting burden when contracts, hedging relationships, and other transactions that reference LIBOR as a benchmark rate are modified. This guidance is effective upon issuance and expires on December 31, 2022. The Company is currently assessing the impact of the LIBOR transition and this ASU on the Company’s financial statements and any agreements utilizing LIBOR, including the Tax Receivable Agreement, but does not currently expect to have a material impact on our financial statements.

3. Property, Plant and Equipment

Property, plant and equipment are stated at cost. We manufacture or construct most of our systems. During the manufacturing of these assets, they are reflected as systems in process until complete. Modifications to existing systems,

On ~~April 26, 2019,~~February 24, 2022, Solaris LLC ~~entered into an~~executed the first amendment (the “2022 Amendment”) to the Amended and Restated Credit Agreement (the ~~“2019 Credit~~“Credit Agreement”), which was originally entered into on April 26, 2019, by and among Solaris LLC, as borrower, each of the lenders party thereto and Wells Fargo Bank, National Association, as administrative agent. The ~~2019~~2022 Amendment extended the maturity date of the Credit Agreement to April 26, 2025 and modified applicable interest rates and repayment requirements.

The Credit Agreement consists of an initial $50.0 revolving loan commitment (the “Loan”) with a $25.0 uncommitted accordion option to increase the Loan availability to $75.0.

~~The term~~ As of the 2019 Credit Agreement expires on April 26, 2022. The 2019 Credit Agreement requires that we prepay any outstanding borrowings under the Loan in the event our total leverage ratio is greater than 1.00 to 1.00 and our consolidated cash balance exceeds $20.0, taking into account certain adjustments. At SeptemberJune 30, ~~2021,~~2022, we had 0 borrowings under the ~~2019~~ Credit Agreement outstanding and ability to draw $50.0.

~~Although there were 0 borrowings outstanding~~Our obligations under the ~~2019~~Loan are generally secured by a pledge of substantially all the assets of Solaris LLC and its subsidiaries, and such obligations are guaranteed by Solaris LLC’s domestic subsidiaries other than Immaterial Subsidiaries (as defined in the Credit Agreement). We have the option to prepay the loans at any time without penalty.

Borrowings under the Credit Agreement, following the 2022 Amendment, bear interest at either Term Secured Overnight Financing Rate (“SOFR”) or an alternate base rate plus an applicable margin, and interest is payable quarterly for alternate base rate loans or the last business day of the interest period applicable to SOFR loans. The applicable margin ranges from 2.75% to 3.50% for SOFR loans and 1.75% to 2.50% ~~for Eurodollar loans and 0.75% to 1.50%~~ for alternate base rate loans, in each case depending on our total leverage ratio. The ~~2019~~ Credit Agreement requires that we pay a quarterly commitment fee on undrawn amounts of the Loan, ranging from ~~0.25%~~0.375% to ~~0.375%~~0.5% depending upon the total leverage ratio. We

The Credit Agreement requires that we maintain ratios of (i) consolidated EBITDA to interest expense of not less than 2.75 to 1.00, (ii) senior indebtedness to consolidated EBITDA of not more than 2.50 to 1.00 and (iii) the sum of 100% of eligible accounts, inventory and fixed assets to the total revolving exposure of not less than 1.00 to 1.00 when the total leverage ratio is greater than 2.00 to 1.00 and total revolving exposure under the Loan exceeds $3.0. For the purpose of these tests, certain items are subtracted from indebtedness and senior indebtedness. EBITDA, as defined in the Credit Agreement, excludes certain noncash items and any extraordinary, unusual or nonrecurring gains, losses or expenses.

Following the 2022 Amendment, the Credit Agreement also requires that we prepay any outstanding borrowings in the event our total consolidated cash balance exceeds $20.0 on the last business day of every other calendar week, taking into account certain adjustments. Capital expenditures are not restricted unless borrowings under the Loan exceed $5.0 for any 180 consecutive day period, in which case capital expenditures will be permitted up to $100.0 plus any unused availability for capital expenditures from the immediately preceding fiscal year.

As of June 30, 2022, we were in compliance with all covenants ~~in accordance with~~under the ~~2019~~ Credit ~~Agreement as of September 30, 2021.~~Agreement.

Income (Loss) Per Share

Basic income (loss) per share of Class A common stock is computed by dividing net income (loss) attributable to Solaris Inc. by the weighted-average number of shares of Class A common stock outstanding during the same period. Diluted income (loss) per share is computed giving effect to all potentially dilutive shares.

6. Income Taxes

Income Taxes

Solaris Inc. is a corporation and, as a result, is subject to United States federal, state and local income taxes. Solaris LLC is treated as a partnership for United States federal income tax purposes and therefore does not pay United States federal income tax on its taxable income. Instead, the Solaris LLC unitholders, including Solaris Inc., are liable for United States federal income tax on their respective shares of Solaris LLC’s taxable income reported on the unitholders’ United States federal income tax returns. Solaris LLC is liable for income taxes in those states not recognizing its status as a partnership for United States federal income tax purposes.

For the three months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, we recognized a combined United States federal and state (expense)/benefit for income taxes of ($~~0.5)~~1.9) and ~~$0.8,~~$0.2, respectively. For the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, we recognized a combined United States federal and state (expense)/benefit for income taxes of ($~~0.1)~~3.6) and ~~$8.2,~~$0.4, respectively. The effective combined United States federal and state income tax rates were ~~26.2%~~19.0% and ~~13.1%~~10.4% for the three months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, respectively. The effective combined United States federal and state income tax rates were ~~3.4%~~20.2% and ~~14.5%~~10.2% for the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, respectively. For the three

Table of Contents

and ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, our effective tax rate differed from the statutory rate primarily due to Solaris LLC’s treatment as a partnership for United States federal income tax purposes.

~~Table of Contents~~

The Company’s deferred tax position reflects the net tax effects of the temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax reporting. The largest components of the Company’s deferred tax position relate to the Company’s investment in Solaris LLC and net operating loss carryovers. The Company recorded a deferred tax asset and additional paid-in capital for the difference between the book value and the tax basis of the Company’s investment in Solaris LLC. This difference originates from the equity offerings of Class A common stock, exchanges of Solaris LLC Units (together with a corresponding number of shares of Class B common stock) for shares of Class A common stock, and issuances of Class A common stock, and corresponding Solaris LLC Units, in connection with stock-based compensation.

Based on our cumulative earnings history and forecasted future sources of taxable income, we believe that we will be able to realize our deferred tax assets in the future. As the Company reassesses this position in the future, changes in cumulative earnings history, excluding non-recurring charges, or changes to forecasted taxable income may alter this expectation and may result in an increase in the valuation allowance and an increase in the effective tax rate.

Section 382 of the Internal Revenue Code of 1986, contains rules that limit the ability of a company that undergoes an “ownership change” to utilize its net operating loss and tax credit carryovers and certain built-in losses recognized in years after the “ownership change.” An “ownership change” is generally defined as any change in ownership of more than 50% of a corporation’s stock over a rolling three-year period by stockholders that own (directly or indirectly) 5% or more of the stock of a corporation, or arising from a new issuance of stock by a corporation. If an ownership change occurs, Section 382 generally imposes an annual limitation on the use of pre-ownership change net operating loss carryovers to offset taxable income earned after the ownership change. We do not believe the Section 382 annual limitation related to historical ownership changes impacts our ability to utilize our net operating losses; however, if we were to experience a future ownership change our ability to use net operating losses may be impacted.

The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted on March 27, 2020 in the United States to provide emergency assistance to individuals and businesses affected by the COVID-19 pandemic. The CARES Act includes temporary changes to both income and non-income based tax laws. For the three and nine months ended September 30, 2021 and 2020 the impact of the CARES Act was immaterial to the Company’s tax provision. However, under the CARES Act, the Company is deferring the employer portion of payroll tax payments through December 31, 2022. Future regulatory guidance under the CARES Act or additional legislation enacted by Congress in connection with the COVID-19 pandemic could impact our tax provision in future periods.

The Company qualified for federal government assistance through employee retention credit provisions of the Consolidated Appropriations Act of 2021. During the three and nine months ended September 30, 2021, the Company recorded $3.1 of employee retention credits in other income on its consolidated income statements. As of September 30, 2021, $1.2 of the credits have been received and $1.9 is included in prepaid expenses and other current assets on the consolidated balance sheet. The calculation of the credit is based on employees continued employment and represents a portion of the wages paid to them. For income tax purposes, the credit will result in decreased expense related to the wages it offsets in the period received. The Company accounted for the employee retention credit as a government grant in accordance with ASU Topic 958, Not-for-Profit Entities – Revenue Recognition.

Payables Related to the Tax Receivable Agreement

~~In connection with Solaris Inc.’s initial public offering (the “IPO” or~~As of June 30, 2022, our liability under the ~~“Offering”), Solaris Inc. entered into a~~ Tax Receivable Agreement (the “Tax Receivable Agreement”) with the members of Solaris LLC immediately prior to the IPO (each such person and any permitted transferee, a “TRA Holder,” and together, the “TRA Holders”) on May 17, 2017. This agreement generally provides for the payment by Solaris Inc. to each TRA Holder ofwas $72.6, representing 85% of the net cash savings ~~if any,~~ in United States federal, state and local income tax ~~and~~or franchise tax that Solaris Inc. ~~actually realizes (computed using simplifying assumptions to address the impact of state and local taxes) or is deemed to realize~~anticipates realizing in ~~certain circumstances in periods after the IPO as a result of (i)~~future years from certain increases in tax basis ~~that occur as a result of Solaris Inc.’s acquisition (or deemed acquisition for United States federal income~~and certain tax ~~purposes) of all or a portion of such TRA Holder’s Solaris LLC Units in connection with the IPO or pursuant~~benefits attributable to ~~the exercise of the Redemption Right or the Call Right (each as defined in Solaris LLC’s Second Amended and Restated Limited Liability Company Agreement) and (ii)~~ imputed interest ~~deemed to be paid by Solaris Inc.~~ as ~~a result of, and additional tax basis arising from, any payments Solaris Inc. makes under the Tax Receivable Agreement. Solaris Inc. will retain the benefit of the remaining 15% of~~

these cash savings. As of September 30, 2021 and December 31, 2020, Solaris Inc. recorded a payable related to the Tax Receivable Agreement of $73.5 and $68.7, respectively, $0.6 and $0.6 of which has been recorded as a current liability, respectively. The increase in payables related to the Tax Receivable Agreement is a result of Solaris Inc.’s acquisition (or deemed acquisition for United States federal income tax purposes) of Solaris LLC Units in connection with our initial public offering or pursuant to an exercise of the Redemption Right or the Call Right (each as defined in the Solaris LLC Agreement) and additional tax basis arising from ~~TRA Holders during~~any payments Solaris Inc. makes under the ~~nine months ended September 30, 2021.~~Tax Receivable Agreement.

On June 16, 2022, Cause Number CV20-09-372, styled Solaris Oilfield Site Services v. Brown County Appraisal District, was presented to the 35th District Court of Brown County, Texas. The 35^th District Court of Brown County ruled in favor of Brown County Appraisal District regarding the disqualification of our equipment for certain property tax exemptions. While we intend to vigorously appeal this ruling, we have recognized $3.1 in Accrued Liabilities and Cost of sales in the three and six month periods ended June 30, 2022. If this litigation is ultimately resolved against us, in whole or in part, it is possible that the resolution of this matter could be material to our consolidated results of operations or cash flows.

Litigation and Claims

In the normal course of business, the Company is subjected to various claims, legal actions, contract negotiations and disputes. The Company provides for losses, if any, in the year in which they can be reasonably estimated.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

References to “we,” “us,” “our,” “Solaris Inc.” or the “Company” refer to Solaris Oilfield Infrastructure, Inc. (either individually or together with its subsidiaries, as the context ~~requires, “we,” “us,” “our,” “Solaris Inc.” or the “Company”)~~requires). The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the accompanying financial statements and related notes. The following discussion contains “forward-looking statements” that reflect our plans, estimates, beliefs and expected performance. Our actual results may differ materially from those anticipated as discussed in these forward-looking statements as a result of a variety of risks and uncertainties, including those described above in “Cautionary Statement Regarding Forward-Looking Statements” included elsewhere in this Quarterly Report and “Risk Factors” included in this Quarterly Report and ~~the~~in our Annual Report on Form 10-K for the year ended December 31, ~~2020~~2021, as updated by our subsequent filings with the United States Securities and Exchange Commission (the “SEC”), all of which are difficult to predict. In light of these risks, uncertainties and assumptions, the forward-looking events discussed may not occur. We assume no obligation to update any of these forward-looking statements except as otherwise required by law.

Overview

We design and manufacture specialized equipment, which combined with field technician support, last mile logistics services and our software solutions, enables us to provide a service offering that helps oil and natural gas operators and their suppliers to drive efficiencies that reduce operational footprint and ~~reduce~~ costs during the completion phase of well development. The majority of our revenue is currently derived from ~~rental~~providing equipment and services related to our ~~patented~~ mobile proppant and ~~patent-pending water and chemical~~fluid management systems and our last mile logistics management services. We also generate revenue from new technology and offerings that ~~unload, store and deliver~~work in conjunction with our mobile proppant and ~~chemicals used in the hydraulic fracturing of oil~~fluid management systems, including our proprietary top fill equipment and ~~natural gas wells, as well as coordinating the delivery of proppant to the well site.~~AutoBlend™ integrated electric blender. Our ~~systems~~equipment and services are deployed in most of the active oil and natural gas basins in the United States.

~~Our service fleet currently consists of 158 mobile proppant management systems, 14 mobile chemical management systems and 17 mobile water management systems.~~

Recent Trends and Outlook

~~Demand~~Oil and gas supply and demand dynamics remained tight throughout the second quarter of 2022. Recent volatility in global markets driven by continued monetary policies to control inflation, continued geopolitical factors and the uncertainty of a potential global economic slowdown contributed to WTI oil prices ranging from $95 per barrel to over $120 per barrel between April and June 2022. While commodity prices remain at healthy levels to support growth in North American drilling and completion activity, this growth continues to be impacted by capital discipline among many operators, supply chain tightness and inflation.

The Baker Hughes Land rig count has increased 29% since the start of the year to 737 rigs at the end of June 2022, as compared to a 32% increase in our fully utilized systems since the fourth quarter of 2021. Overall, demand for our ~~products and services~~offerings is predominantly influenced by the level of oil and natural gas well drilling and completion ~~activity, which, in turn, is determined by the current and anticipated profitability of developing oil and natural gas reserves.~~

The oil and natural gas industry continues to recover from the impacts of the COVID-19 pandemic, which, beginning with the first quarter of 2020, drove extreme volatility in oil and natural gas commodity prices and activity. During this time period, WTI oil prices fell from $60 per barrel to under $20 per barrel during the second quarter of 2020 and have recovered to over $80 per barrel in October 2021. The Baker Hughes US Land rig count decreased 55% to 417 average rigs in 2020 from 920 average rigs in 2019. Since the start of 2021, the Baker Hughes US Land rig count has increased 50% to 515 rigs compared to a 41% increase in our fully utilized systems since the fourth quarter of 2020. While our fully utilized systems are highly correlated with US land rig count activity over longer periods, timing differences between drilling and completion activity can result in lags of one to two quarters or longer. ~~Further stabilization in oil~~

The sustainability of favorable supply-demand dynamics and ~~gas prices and activity~~a strong commodity environment will depend on multiple factors, including ~~the ultimate pace of economic recovery, the success of COVID-19 vaccine rollouts,~~any supply chain disruptions, potential regulatory changes, uncertainty around a potential economic slowdown and ~~the resulting supply-demand balance in oil and gas.~~

~~Recent~~ ~~consolidation~~potential impacts from geopolitical disruptions. Consolidation amongst some of our E&P and oil service customers combined with financial discipline from publicly traded energy companies has reduced industry-wide capital ~~spending, resulting in activity levels that remain below pre-pandemic levels despite the recovery in commodity prices.~~spending. Additionally, consolidation can drive procurement strategy changes, which has historically resulted in both market share gains and losses for the Company. We expect both consolidation and financial discipline will likely continue to be important themes for the energy industry going forward.

~~The Company expects capital expenditures for the full year 2021 to be approximately $20.0 million.~~

Property Tax Contingency

We are subject to a number of state and local taxes that are not income-based. As many of these taxes are subject to assessment and audit by the taxing authorities, it is possible that an assessment or audit could result in additional taxes due. We accrue for additional taxes when we determine that it is probable that we will have incurred a liability and we can reasonably estimate the amount of the liability. On June 16, 2022, Cause Number CV20-09-372, styled Solaris Oilfield Site Services v. Brown County Appraisal District, was presented to the 35th District Court of Brown County, Texas. The 35th District Court of Brown County ruled in favor of Brown County Appraisal District regarding the disqualification of our equipment for certain property tax exemptions. While we intend to vigorously appeal this ruling, we have recognized $3.1 in Accrued Liabilities and Cost of ~~system rental increased $1.4 million, or 115%, to $2.5 million for~~sales in the three ~~months~~and six month periods ended ~~September~~June 30, ~~2021 compared~~2022. If this litigation is ultimately resolved against us, in whole or in part, it is possible that the resolution of this matter could be material to ~~$1.2 million for the three months ended September 30, 2020, excluding depreciation and amortization expense. Cost~~our consolidated results of ~~system rental increased $1.7 million,~~operations or 42%, to $5.7 million for the nine months ended September 30, 2021 compared to $4.0 million for the nine months ended September 30, 2020, excluding depreciation and amortization expense. Cost of system rental increased primarily due to an increase in mobile proppant systems on a fully utilized basis. Cost of system rental as a percentage of system rental revenue was 16% and 13% for the three months ended September 30, 2021 and 2020, respectively and was 13% and 10% for the nine months ended September 30, 2021 and 2020, respectively.

~~System Services~~

System services revenue increased $22.1 million, or 204%, to $33.0 million for the three months ended September 30, 2021 compared to $10.9 million for the three months ended September 30, 2020. System services revenue increased $33.1 million, or 94%, to $68.3 million for the nine months ended September 30, 2021 compared to $35.2 million for the nine months ended September 30, 2020. System services revenue increased mainly due to an increase in last mile services provided to coordinate proppant delivered into our systems, as well as an increase in mobile proppant systems on a fully utilized basis.

Cost of system services increased $22.5 million, or 171%, to $35.6 million for the three months ended September 30, 2021 compared to $13.1 million for the three months ended September 30, 2020, excluding depreciation and amortization expense. Cost of system services increased $32.9 million, or 76%, to $76.2 million for the nine months ended September 30, 2021 compared to $43.3 million for the nine months ended September 30, 2020, excluding depreciation and amortization expense. Cost of system services increased mainly due to an increase in last mile services provided to coordinate proppant delivered to systems as well as an increase in fully utilized systems. Cost of system services as a percentage of system services revenue was 108% and 121% for the three months ended September 30, 2021 and 2020, respectively and was 111% and 123% for the nine months ended September 30, 2021 and 2020, respectively.cash flows.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased ~~$1.0~~$1.1 million, or ~~24%~~22%, to ~~$4.8~~$6.1 million for the three months ended ~~September~~June 30, ~~2021~~2022 compared to ~~$3.8~~$5.0 million for the three months ended ~~September~~June 30, ~~2020, excluding depreciation and amortization.~~2021. Selling, general and administrative expenses increased ~~$2.1~~$1.7 million, or ~~17%~~18%, to ~~$14.3~~$11.3 million for the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 compared to ~~$12.2~~$9.6 million for the ~~nine~~six months ended ~~September~~June 30, ~~2020, excluding depreciation and amortization expense.~~2021. Selling, general and administrative expenses increased due primarily to increases in headcount and professional fees.

Other Operating (Income) Expense

~~The Company qualified for federal government assistance through employee retention credit provisions~~Other operating (income) expense decreased $1.5 million, or 375% to income of ~~the Consolidated Appropriations Act of 2021. During the three and nine months ended September 30, 2021, the Company recorded $3.1~~$1.1 million of employee retention credits in other income on its consolidated income statements. As of September 30, 2021, $1.2 million of the credits have been received and $1.9 million is included in prepaid expenses and other current assets on the consolidated balance sheet. The calculation of the credit is based on employees continued employment and represents a portion of the wages paid to them. For income tax purposes, the credit will result in decreased expense related to the wages it offsets in the period received.

~~Impairment Losses~~

As a result of risks and uncertainties associated with volatility in global oil markets driven by significant reductions in demand for oil due to COVID-19 and certain actions by oil producers globally and the expected impact on our businesses, operations, earnings and results, we recorded impairment losses and other charges of $37.8 million, $4.2 million, $2.8 million, $2.6 million and $0.4 million in relation to property, plant and equipment, goodwill, ROU assets, inventories and other assets, respectively, in the nine months ended September 30, 2020. We did not record impairment losses in the three or nine months ended September 30, 2021, respectively, nor for the three months ended ~~September~~June 30, ~~2020.~~

~~Table~~2022 compared to the expense of ~~Contents~~$0.4 million for the three months ended June 30, 2021. Other operating (income) expense decreased $2.0 million, or 333% to income of $1.4 million for the six months ended June 30, 2022 compared to the expense of $0.6 million for the six months ended June 30, 2021. Other operating income in the three and six months ended June 30, 2022 primarily relate to change in the TRA liability, credit losses, gain on insurance claims, loss on disposal of assets, and the write off of prepaid purchase orders that were not fulfilled. Other operating expense in the three and six months ended June 30, 2021 primarily relate to credit losses, gain on insurance claims, and loss on disposal of assets.

Provision for Income Taxes

During the three months ended ~~September~~June 30, ~~2021,~~2022, we recognized a combined United States federal and state expense for income taxes of ~~$0.5~~$1.9 million, ~~a decrease~~an increase of ~~$1.3~~$2.1 million as compared to the ~~$0.8~~$0.2 million income tax benefit we recognized during the three months ended ~~September~~June 30, ~~2020.~~2021. During the ~~nine~~six months ended ~~September~~June 30, ~~2021,~~2022, we recognized a combined United States federal and state expense for income taxes of ~~$0.1~~$3.6 million, ~~a decrease~~an increase of ~~$8.3~~$4.0 million as compared to the ~~$8.2~~$0.4 million income tax benefit we recognized during the ~~nine~~six months ended ~~September~~June 30, ~~2020.~~2021. This change was attributable to ~~lower~~ operating ~~losses.~~gains. The effective combined United States federal and state income tax rates were ~~26.2%~~19.0% and ~~13.1%~~10.4% for the three months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, respectively. The effective combined United States federal and state income tax rates were ~~3.4%~~20.2% and ~~14.5%~~10.2% for the ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, respectively. The effective tax rate differed from the statutory rate primarily due to Solaris LLC’s treatment as a partnership for United States federal income tax purposes.

Comparison of Non-GAAP Financial Measures

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 any extraordinary, unusual or non-recurring gains, losses or expenses.

Table of Contents

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 accounting standards generally accepted in the United States (“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 Net income to EBITDA and Adjusted EBITDA for each of the periods indicated.

Liquidity and Capital Resources

Overview

Our primary sources of liquidity to date have been cash flows from operations, borrowings under our credit agreements and proceeds from equity offerings. Our primary uses of capital have been to fund ongoing operations,

Table of Contents

capital expenditures to support organic growth, including our fleet development and related maintenance and fleet upgrades, repurchase shares of Class A common stock in the open market, and pay dividends. Although no assurance

~~Table of Contents~~

can be given, depending upon market conditions and other factors, we may also have the ability to issue additional equity and debt if needed.

As of ~~September~~June 30, ~~2021,~~2022, cash and cash equivalents totaled ~~$42.8~~$15.4 million. We have no borrowings outstanding under our ~~2019~~ Credit Agreement and have $50.0 million of available borrowing capacity. We believe that our cash on hand, operating cash flow and available borrowings under our ~~2019~~ Credit Agreement will be sufficient to fund our operations for at least the next 12 months.
