You should read the following discussion of our historical performance, financial condition and prospects in conjunction with our unaudited condensed consolidated financial statements as of and for the three and nine months ended September 30, 2021. The information provided below supplements, but does not form part of, our historical financial statements. This discussion includes forward-looking statements that are based on the views and beliefs of our management, as well as assumptions and estimates made by our management. The financial data discussed below reflect the historical results of operations and financial position of Solaris LLC, Aris' predecessor for accounting purposes prior to the initial public offering. Actual results could differ materially from such forward-looking statements because of various risk factors, including those that may not be in the control of management.

Initial Public Offering

On October 21, 2021, Aris announced the pricing of its initial public offering of 17,650,000 shares of its Class A common stock at a price to the public of $13.00 per share. In addition, Aris granted the underwriters a 30-day option to purchase up to an additional 2,647,500 shares of its Class A common stock at the public offering price, less underwriting discounts and commissions. On October 22, 2021, the underwriters fully exercised such option to purchase an additional 2,647,500 shares of Class A common stock. The Class A common stock began trading on the New York Stock Exchange under the ticker symbol "ARIS" on October 22, 2021, and the offering, including the underwriters' option, closed on October 26, 2021.

The closing of the initial public offering, including the underwriters' option, resulted in net proceeds of approximately $246.1 million, after deducting underwriting discounts and commissions and estimated expenses payable by Aris. Aris contributed all the net proceeds of the initial public offering to Solaris LLC in exchange for a single class of units in Solaris LLC and shares of the Company's Class B common stock. Solaris LLC distributed approximately $213.3 million of the net proceeds to the existing owners of Solaris LLC and retained the remaining $32.8 million of the net proceeds for general corporate purposes, which may include capital expenditures, working capital and potential acquisitions and strategic transactions.

General Trends and Outlook

Market Dynamics

During the three and nine months ended September 30, 2021, the average West Texas Intermediate ("WTI") spot price was $70.58 and $65.05, respectively, representing a significant rebound from $39.16 for the year ended December 31, 2020. With the increase in WTI spot prices, the production curtailment activities experienced in 2020 have stopped and investment in new production activities has resumed. We believe that the activity levels of our customers will continue to increase above 2020 levels.

We believe there are several industry trends that continue to provide meaningful support for future growth. Our key customers are allocating new capital to the Permian Basin including acreage where the water sourcing and production is dedicated to Aris. Additionally, operators continue to increase horizontal lateral lengths which corresponds to increased water sourcing and produced water handling volumes.

Many industry trends such as multi-well pad development and the trend towards reuse applications of produced water, particularly in the areas of the Permian Basin where we operate, are improving efficiencies and returns and provide us with significant opportunities for both our Produced Water Handling and Water Solutions businesses.

COVID-19 Pandemic

COVID-19 contributed to a significant downturn in oil and gas commodity prices in 2020 and continues to cause significant volatility in 2021. Although we cannot predict future commodity prices, we are not currently experiencing significant disruptions with our workforce or supply chain activities. Moreover, we continue to maintain our focus on safe and reliable performance of our systems, while ensuring the safety of our employees and other stakeholders. However, we are unable to predict the future impact of COVID-19, and it is possible that such impact could be negative.

How We Generate Revenue

We manage our business through a single operating segment comprising two primary revenue streams, Produced Water Handling and Water Solutions. Our Produced Water Handling revenues are driven by the volumes of produced water we gather from our customers, and our Water Solutions revenues are driven by the quantities of recycled produced water and groundwater delivered to our customers to support their well completion operations.

Under our contracts with our customers, which are generally subject to annual CPI-based adjustments, we receive a fixed fee per barrel of produced water received from our customers, which water is either handled or recycled, and a fixed fee per barrel of recycled water or groundwater sold to our customers.

Costs of Conducting Our Business

Operating Expenses

We incur operating costs primarily as a function of the number of barrels of water received, handled and treated. The major categories of operating costs are landowner royalties, power expenses for handling and treatment facilities, direct labor, chemicals for water treatment, water filtration expenses and repair and maintenance of facilities. We seek to minimize, to the extent appropriate for safe and reliable operations, expenses directly tied to operating and maintaining our assets.



                                       31

Table of Contents

General and Administrative Expenses

General and administrative expenses are costs incurred for overhead, including payroll and benefits for our corporate staff, costs of maintaining our offices, costs of managing our permitting operations, information technology expenses, audit and other fees for professional services.

How We Evaluate Our Results of Operations

We use a variety of financial and operational metrics to evaluate our performance. These metrics help us identify factors and trends that impact our operating results, cash flows and financial condition. The key metrics we use to evaluate our business are provided below.

Produced Water Handling Volumes

We continually seek to bring additional produced water volumes onto our system to maintain or increase throughput on our systems. These volumes are a primary revenue driver and serve as a water source for our Water Solutions business. Changes in produced water handling throughput are driven primarily by the level of production and pace of completions activity on our contracted acreage. We define Produced Water Handling Volumes as all produced water barrels received from customers and any barrels that are deficient under minimum volume commitment agreements.

Water Solutions Barrels Sold and Transferred

Our recycled water and groundwater sales are primarily driven by our customers' completion activities. We continually seek to gain market share and expand our customer base for recycled water and groundwater sales in the Permian Basin. Our access to abundant produced water volumes and the scale of our systems allows us to distribute recycled water for our customers' completion activities in an efficient, cost effective, and environmentally conscious manner. We define Water Solutions Barrels Sold and Transferred as the total of all recycled water and groundwater barrels sold plus groundwater barrels transferred on behalf of third parties.

Revenue

We analyze our revenue and assess our performance by comparing actual revenue to our internal projections and across periods. We examine revenue per barrel of water handled or sold to evaluate pricing trends and customer mix impacts. We also assess incremental changes in revenue compared to incremental changes in direct operating costs and selling, general and administrative expenses to identify potential areas for improvement and to determine whether our performance is meeting our expectations.

We generate revenue by providing fee-based services related to produced water handling and water solutions.

The services related to produced water are fee-based arrangements which are based on the volume of water that flows through our systems and facilities. Revenues from produced water handling consist primarily of per barrel fees charged to our customers for the use of our transportation and water handling services. For our produced water handling contracts, revenue is recognized over time utilizing the output method based on the volume of produced water accepted from the customer.

The sale of recycled produced water and groundwater are priced based on negotiated rates with our customers. For contracts that involve recycled produced water and groundwater, revenue is recognized at a point in time when control of the product is transferred to the customer.

Adjusted EBITDA

We use Adjusted EBITDA as a performance measure to assess the ability of our assets to generate sufficient cash to pay interest costs, support indebtedness and return capital to equity holders. Adjusted EBITDA is a Non-GAAP financial measure. We define Adjusted EBITDA as net income (loss) plus: interest expense? income taxes? depreciation, amortization and accretion expense? abandoned well costs, asset impairment and abandoned project charges? losses on the sale of assets? loss on debt modification? and non-recurring or unusual expenses or charges (including temporary power costs discussed below), less any gains on sale of assets. (See Non-GAAP Measures discussed below for more information regarding this financial measure, including a reconciliation to its most directly comparable GAAP measure.)

Adjusted Operating Margin and Adjusted Operating Margin per Barrel

Our Adjusted Operating Margin and Adjusted Operating Margin per Barrel are dependent upon the volume of produced water we gather and handle, the volume of recycled water and groundwater we sell and transfer, the fees we charge for such services, and the recurring operating expenses we incur to perform such services. We define Adjusted Operating Margin as Gross Margin plus depreciation, amortization and accretion and temporary power costs. We define Adjusted Operating Margin per Barrel as Adjusted Operating Margin divided by total volumes handled, sold or transferred. Adjusted Operating Margin and Adjusted Operating Margin per Barrel are non-GAAP financial measures. (See Non-GAAP Measures discussed below for more information regarding this financial measure, including a reconciliation to its most directly comparable GAAP measures for each measure.)

We seek to maximize our Adjusted Operating Margin in part by minimizing, to the extent appropriate, expenses directly tied to operating our assets. Landowner royalties, utilities, direct labor costs, chemical costs, repair and maintenance costs, and contract services comprise the most significant portion of our expenses. Our operating expenses are largely variable and as such, generally fluctuate in correlation with throughput volumes.

Our Adjusted Operating Margin is incrementally benefited from increased Water Solutions recycling sales. When produced water is recycled, we recognize cost savings from reduced landowner royalties, reduced pumping costs, lower chemical treatment and filtration costs, and reduced power consumption.

Temporary Power Costs

In the past, we constructed assets in advance of permanent grid power infrastructure availability in order to secure long- term produced water handling contracts. As a result, we rented temporary power generation equipment that would not have been necessary if grid power connections had been available. We estimate temporary power costs by taking temporary power and rental expenses incurred during the period and subtracting estimated expenses that would have been incurred during such period had permanent grid power been available. Power infrastructure and permanent power availability rapidly expanded in the Permian Basin in 2020 and the first half of 2021, and accordingly, we were able to make significant progress in reducing these expenses over that period. By the end of June 2021, all our significant facilities were being supported by permanent power.

We remove temporary power costs when calculating Adjusted Operating Margin to accurately assess long-term profitability and cash flow on a basis consistent with our long-term projections and current operating cost profile.

Factors Affecting the Comparability of Our Results of Operations

Concho Acquisitions

On June 11, 2020, we acquired certain produced water handling and transportation assets in Lea County, New Mexico from a wholly owned subsidiary of Concho, which was acquired by ConocoPhillips in January 2021 (the "Lea County Acquisition"). See Note 4 - Acquisitions.

We processed 119,000 and 19,000 barrels per day of produced water volumes associated with the Lea County Acquisition for the nine months ended September 30, 2021 and 2020, respectively.

Produced Water Handling Revenues

Total produced water handling revenues increased for third quarter 2021 compared to third quarter 2020 by $11.1 million, or 30%. For the nine months ended September 30, 2021, total produced water handling revenues increased $27.9 million, or 26%, compared to the nine months ended September 30, 2020. These increases are primarily due to:

an overall increase of 134 kbwpd and 126 kbwpd for the comparative three- and

nine-month periods, respectively, due to an increase of activity associated

? with our new and previously contracted long-term acreage dedication agreements,

including the ramp up of activities on the Lea County acreage dedication

acquired by us in June of 2020, and

? an increase in the weighted average produced water handling price per barrel

due to contractual price adjustments.

Water Solutions Revenue

Water solutions revenues increased for third quarter 2021 compared to third quarter 2020, by $5.9 million, or 101%. For the nine months ended September 30, 2021, water solutions revenues increased $7.8 million, or 37%, compared to the nine months ended September 30, 2020. These increases in water solutions revenue are primarily due to:

an overall increase of 152 kbwpd and 102 kbwpd for the comparative three- and

nine-month periods, respectively, principally due to higher recycling volumes.

? The increase in water solutions volumes is due to the increase in completion

activities across the Permian basin in response to recovering commodity prices,

partially offset by,

a decrease in the weighted average price for water sold. The decrease in price

is attributable to the increase of the amount of recycled water, versus ground

? water, sold. Although recycled water sales improve our overall profitability,

we contract recycled water volumes at lower prices relative to ground water


   volumes.


Direct Operating Costs

For the third quarter in 2021, direct operating costs were $23.5 million compared to $22.2 million for the third quarter of 2020, an increase of $1.3 million, or 6%. The increase is primarily due to increased Water Solutions volumes.

On a per barrel basis, direct operating costs per barrel were $0.27 per barrel compared to $0.36 per barrel for the third quarter of 2021 and 2020, respectively. Direct operating costs per barrel improved primarily due to reduced temporary power generation expenses and increased recycled volumes sold, which have a lower operating cost per barrel.

All our significant facilities were on permanent power during the third quarter of 2021, and therefore we did not adjust for any temporary power expenses. For third quarter 2020, the estimated incremental impact of temporary power expenses was $3.5 million, or approximately $0.06 per barrel.

For the nine months ended September 30, 2021, direct operating costs were $66.7 million compared to $71.6 million for the nine months ended September 30, 2020, a decrease of $4.9 million, or 7%. The decrease in direct operating costs is primarily due to reduced temporary power generation expenses. As a result, for the nine months ended September 30, 2021, direct operating costs was $0.27 per barrel for the nine months ended September 30, 2021 compared to $0.39 per barrel for the nine months ended September 30, 2020.

Estimated incremental impacts of temporary power expenses were $4.3 million and $12.7 million for the nine months ended September 30, 2021 and 2020, respectively. See "How We Evaluate Our Results of Operations-Temporary Power Costs" for additional information.

Depreciation, Amortization and Accretion Expenses

For the three months ended September 30, 2021, depreciation, amortization and accretion expense was $15.4 million compared to $11.8 million for the three months ended September 30, 2020, an increase of $3.6 million, or 31%. For the nine months ended September 30, 2021, depreciation, amortization and accretion expenses were $45.6 million compared to $31.5 million for the nine months ended September 30, 2020, an increase of $14.1 million, or 45%. These increases are primarily due to the amortization of customer contracts related to the Lea County Acquisition, incremental assets from the Lea County Acquisition, and continued asset construction.

Abandoned Well Costs

In late third quarter 2021, management completed its evaluation of the performance of a saltwater disposal asset, located in Eddy County, New Mexico and concluded that the well should be shut-in and taken out of service. We drilled this well in the second quarter of 2017 and encountered technical difficulties requiring significant incremental capital expenditure. The asset was put into service in May of 2018. During July 2021, we re-entered the well bore to address anomalies. After technical testing, management concluded that it was probable that abandoning the asset was the most prudent course of action. Accordingly, we have recognized a charge of $27.4 million, included in abandoned well costs for the remaining net book value of the well. The abandonment did not impact our revenues.

General and Administrative Expenses

For the three months ended September 30, 2021, general and administrative expenses were $5.2 million compared to $4.8 million for the three months ended September 30, 2020, an increase of $0.4 million, or 8%.

For the nine months ended September 30, 2021, general and administrative expenses were $15.2 million compared to $13.4 million for the nine months ended September 30, 2020, an increase of $1.8 million, or 13%. These increases are mainly due to increased compensation and benefits expenses, travel, and insurance costs corresponding with a larger asset footprint.

Other Operating Expenses

Other operating expenses were $0.9 million for the three months ended September 30, 2021, compared to $0.6 million for third quarter 2020. The increase is mainly due to increased expirations of legacy permits and rights-of-way that were ultimately not constructed. On a quarterly basis, we review the status of projects to ensure our commitment and ability to complete the project as planned. If we identify a project where completion is no longer probable, we recognize a charge to earnings for the total costs incurred for that project.

For the nine months ended September 30, 2021, other operating expenses were $2.6 million, compared to $4.9 million for third quarter 2020. The decrease of $2.3 million is primarily due to the non-recurrence of advisory and legal expenses associated with the Lea County Acquisition and non-recurrence of advisory and legal expenses associated with an uncompleted transaction that was terminated in first quarter 2020. This was partially offset by an increase in the expiration of legacy permits and rights-of-way as discussed above.

Interest Expense

Interest expense is as follows:




                                               Three Months Ended       Nine Months Ended

Net interest expense increased $5.8 million in third quarter 2021 compared to third quarter 2020. The increase is primarily due to an increase in the total debt outstanding and an increase in the interest rate related to our debt instruments. For third quarter 2021, our outstanding debt balance was $400 million, all of which is attributable to our sustainability linked notes, compared to the third quarter 2020 balance of $286.7 million related to our credit facility. The interest rate on our sustainability-linked notes is 7.625%, whereas the third quarter 2020 rate on the credit facility was 3.67%. Net interest expense also increased $0.4 million due to higher amortization of financing costs.

Net interest expense increased $12.5 million for the nine months ended September 30, 2021, compared to the nine months ended September 30, 2020. The increase is primarily due to increases in the outstanding debt balance, interest rates and amortization of financing costs as discussed above. The increase is also due to less capitalized interest a result of the reduction in our capital projects and related capital expenditures.

Non-GAAP Financial Measures

Adjusted EBITDA, Adjusted Operating Margin and Adjusted Operating Margin Per Barrel are supplemental non- GAAP measures that we use to evaluate current, past and expected future performance. Although these non-GAAP financial measures are important factors in assessing our operating results and cash flows, they should not be considered in isolation or as a substitute for net income or gross margin or any other measures prepared under GAAP.

Reconciliation of GAAP "Net income" to Non-GAAP "Adjusted EBITDA"

We define Adjusted EBITDA as net income (loss) plus: interest expense; income taxes; depreciation, amortization and accretion expense; abandoned well costs, asset impairment and abandoned project charges; losses on the sale of assets; loss on debt modification; and non-recurring or unusual expenses or charges (including temporary power costs), less any gains on sale of assets.

Reconciliation of GAAP "Gross Margin" to Non-GAAP "Adjusted Operating Margin" and "Adjusted Operating Margin per Barrel"

We define Adjusted Operating Margin as Gross Margin plus depreciation, amortization and accretion and temporary power costs. We define Adjusted Operating Margin per Barrel as Adjusted Operating Margin divided by total volumes.

We believe this presentation is used by investors and professional research analysts for the valuation, comparison, rating, and investment recommendations of companies within our industry. Additionally, we use this information for comparative purposes within our industry. Adjusted EBITDA, Adjusted Operating Margin and Adjusted Operating Margin per Barrel are not measures of financial performance under GAAP and should not be considered as measures of liquidity or as alternatives to net income (loss) or gross margin.

Liquidity and Capital Resources

Overview

Our primary needs for cash are permitting, development and construction of water handling and recycling assets to meet customers' needs, payment of contractual obligations including debt, and working capital obligations. Funding for these cash needs may be provided by any combination of internally generated cash flow, borrowings under the Credit Facility, or accessing the capital markets.

In April 2021, we repaid $297.0 million of total outstanding borrowings under our Credit Facility and redeemed all outstanding redeemable preferred units for $74.4 million with the proceeds from the issuance of $400.0 million of our Senior Sustainability-Linked Notes. We also amended and restated our Credit Facility to provide $200.0 million of committed funds that were undrawn as of September 30, 2021.

As of September 30, 2021, we had working capital, defined as current assets less current liabilities, of $37.5 million and $200.0 million of availability under the Credit Facility.

Cash Flow from Operating Activities

For the nine months ended September 30, 2021, we had Cash Flow Provided by Operating Activities of $57.2 million compared to $50.6 million for the nine months ended September 30, 2020. The increase is primarily driven by increase in revenue as well as changes in working capital driven by timing of collections of accounts receivable and payments of trade accounts payable and interest payable.

Cash Flow Used in Investing Activities

For the nine months ended September 30, 2021, we had Cash Flow Used in Investing Activities of $62.7 million compared to $121.8 million for the nine months ended September 30, 2020. We incurred lower capital expenditures in 2021 compared to 2020 due to lower capital expenditure requirements to meet produced water handling capacity needs.

Cash Flow Provided by Financing Activities

For the nine months ended September 30, 2021, we had Cash Flow Provided by Financing Activities of $17.0 million compared to $72.5 million for the nine months ended September 30, 2020. Cash Flow Provided by Financing Activities for the nine months ended September 30, 2021 of $17.0 million was primarily due to the issuance of our $400.0 million aggregate principal amount of our 7.625% Senior Sustainability-Linked Notes on April 1, 2021 that was used to pay down the Credit Facility of $297.0 million and redeem the Redeemable Preferred Units of $74.4 million. We required less external financing for the nine months ended September 30, 2021 versus the nine months ended September 30, 2020 due to lower capital buildout requirements.

Capital Requirements

Our business is capital intensive, requiring the maintenance of existing pipelines, pumps and handling and recycling facilities and the acquisition or construction and development of new assets and facilities.

Our current level of capital expenditures is expected to remain within our internally generated cash flow as we maintain significant flexibility around the timing of capital expenditures. However, we are subject to certain capital requirements to support our customers' development plans associated with acreage dedication agreements.

Accordingly, we work proactively with our customers to anticipate their future needs for water handling and recycling assets to support their activities. For 2021, we expect our capital expenditures to range from $78-$83 million.

We intend to fund capital requirements through our primary sources of liquidity, which include cash on hand and cash flows from operations and, if needed, our borrowing capacity under the Credit Facility.

Debt Agreements

Credit Facility

On April 1, 2021, we entered into our amended and restated credit agreement (the "Restated Credit Agreement") to, among other things, (i) decrease the commitments under the Credit Facility to $200.0 million, (ii) extend the maturity date to April 1, 2025, (iii) reprice the loans made under the Credit Facility and unused commitment fees to be determined based on a leverage ratio ranging from 3.00:1.00 to 4.50:1.00, (iv) provide for a $75.0 million incremental revolving facility, which shall be on the same terms as under the Credit Facility, (v) annualize EBITDA for 2021 for the purpose of covenant calculations, (vi) amend the leverage ratio covenant to comprise of a maximum total funded debt to EBITDA ratio, net of $40.0 million of unrestricted cash and cash equivalents if the facility is drawn, and net of all unrestricted cash and cash equivalents if the facility is undrawn, (vii) increase the leverage ratio covenant test level for the first two fiscal quarters of 2021



                                       40

to 5.00 to 1.00, for the third quarter of 2021 to 4.75 to 1.00, and thereafter to 4.50 to 1.00 and (viii) add a secured leverage covenant of 2.50 to 1.00. In April 2021, we repaid all borrowings under the prior Credit Facility upon entering into the Restated Credit Agreement. As of September 30, 2021, we were in compliance with all of our covenants under our Credit Facility.

Senior Sustainability-Linked Notes

We have $400.0 million aggregate principal amount of 7.625% Senior Sustainability-Linked Notes outstanding, which are due April 1, 2026. The Notes were issued by Solaris LLC on April 1, 2021 and are unsecured and effectively subordinated to the Credit Facility to the extent of the value of the collateral securing the Credit Facility. The Notes are guaranteed on a senior unsecured basis by all of Solaris LLC's wholly owned subsidiaries. Interest on the Notes is payable on April 1 and October 1 of each year. We may redeem all or part of the Notes at any time on or after April 1, 2023 at redemption prices ranging from 103.8125% on or after April 1, 2023 to 100% on or after April 1, 2025. In addition, on or before April 1, 2023, we may redeem up to 40% of the aggregate principal amount of the Notes with the net cash proceeds of certain equity offerings, if certain conditions are met, at a redemption price of 107.625% of the principal amount of the notes, plus accrued interest. At any time prior to April 1, 2023, we may also redeem the Notes, in whole or in part, at a price equal to 100% of the principal amount of the notes plus a "make-whole" premium.

Certain of these redemption prices are subject to increase if we fail to satisfy the Sustainability Performance Target (as defined in the indenture governing the notes and referred herein as "SPT") and provide notice of such satisfaction to the trustee. If we undergo a change of control, we may be required to repurchase all or a portion of the notes at a price equal to 101% of the principal amount of the notes, plus accrued interest.

We used the proceeds from the issuance of the Notes to repay all borrowings outstanding under our Credit Facility, to redeem our preferred units in full and for general corporate purposes.

The indenture that governs the Notes contains covenants that, among other things, limit our ability and the ability of our restricted subsidiaries to:

? incur or guarantee additional indebtedness or issue certain preferred stock?

? pay dividends on capital stock or redeem, repurchase or retire our capital

stock or subordinated indebtedness?




 ? transfer or sell assets?


 ? make investments?


 ? create certain liens?

? enter into agreements that restrict dividends or other payments from our

restricted subsidiaries to us?

? consolidate, merge or transfer all or substantially all of our assets?

? engage in transactions with affiliates? and

? create unrestricted subsidiaries.

Our key performance indicator under our Sustainability-Linked Bond Framework is to increase recycled produced water sold and reduce groundwater withdrawals sold expressed as a percentage of barrels of recycled produced water sold per year divided by total barrels of water sold per year (the "Recycling KPI").



                                       41

Table of Contents

The Recycling KPI encompasses 100% of our sourcing operations in the Permian Basin. Our Recycling KPI is designed to reduce groundwater withdrawal for water intensive industrial operations in the water stressed Permian Basin by increasing our sales of recycled produced water. Our SPT is to increase our annual Recycling KPI to 60% by 2022 from a 2020 baseline of 42.1%, with an observation date of December 31, 2022.

To the extent the SPT has not been achieved and verified for the year ended December 31, 2022, the coupon on the Notes will increase to 7.875% beginning with the interest period ending on October 1, 2023 until maturity and there will also be an increase in applicable optional redemption prices.

We were in compliance with all covenants under the indenture governing the Notes as of September 30, 2021.

Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in conformity with GAAP requires the selection and application of appropriate accounting principles to the relevant facts and circumstances of our operations and the use of estimates made by management. We have identified the following accounting policies that are most important to the portrayal of our consolidated financial position and results of operations. The application of these accounting policies, which requires subjective or complex judgments regarding estimates and projected outcomes of future events, and changes in these accounting policies, could have a material effect on our financial statements.

Revenue Recognition

We generate revenue by providing services related to Produced Water Handling and Water Solutions. The services related to produced water are fee-based arrangements and are based on the volume of water that flows through our systems and facilities while the sale of recycled produced water and groundwater are priced based on negotiated rates with the customer.

We have customer contracts that contain minimum transportation and/or disposal volume delivery requirements and we are entitled to deficiency payments if such minimum contractual volumes are not delivered by the customer. These deficiency amounts are based on fixed, daily minimum volumes (measured over monthly, quarterly and annual periods depending on the contract) at a fixed rate per barrel. We are typically entitled to shortfall payments if such minimum contractual obligations are not maintained by our customers. We invoice the customer on either a monthly, quarterly or annual basis, as provided in the contract.

We account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers, which was adopted effective January 1, 2019, using the modified retrospective approach. No cumulative adjustment to accumulated earnings was required as a result of this adoption.

In determining the appropriate amount of revenue to be recognized as we fulfill our obligations under the contracts, the following steps must be performed at contract inception: (i) identification of the promised goods or services in the contract? (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract? (iii) measurement of the transaction price, including the constraint on variable consideration? (iv) allocation of the transaction price to the performance obligations? and (v) recognition of revenue when (or as) we satisfy each performance obligation.

Revenues from Produced Water Handling consist primarily of per barrel fees charged to customer for the use of our system and disposal services. For all of our produced water transfer and disposal contracts, revenue will be recognized over time utilizing the output method based on the volume of wastewater accepted from the customer. We typically charge our customers a disposal and transportation fee on a per barrel basis



                                       42

Table of Contents

under our contracts. In some contracts, we are entitled to shortfall payments if minimum contractual obligations are not satisfied by our customers. Minimum contractual obligations have not been maintained, and thus we have recognized revenues related to shortfalls on such take or pay contractual obligations to date. Some contracts also have a mechanism that allows for shortfalls to be made up over a limited period of time.

For contracts that involve recycled produced water and groundwater, revenue is recognized at a point in time, based on when control of the product is transferred to the purchaser or customer, as the case may be.

Acquisitions

To determine if a transaction should be accounted for as a business combination or an acquisition of assets, we first calculate the relative fair values of the assets acquired. If substantially all of the relative fair value is concentrated in a single asset or group of similar assets, or if not but the transaction does not include a significant process (does not meet the definition of a business), we record the transaction as an acquisition of assets. For acquisitions of assets, the purchase price is allocated based on the relative fair values. For an acquisition of assets, goodwill is not recorded. All other transactions are recorded as business combinations.

Fair values of assets acquired and liabilities assumed are based upon available information and may involve engaging an independent third party to perform an appraisal. Estimating fair values can be complex and subject to significant business judgment. We must also identify and include in the allocation all acquired tangible and intangible assets that meet certain criteria, including assets that were not previously recorded by the acquired entity. The estimates most commonly involve property, plant and equipment and intangible assets, including those with indefinite lives. The estimates also include the fair value of contracts. For a business combination, the excess of the purchase price over the net fair value of acquired assets and assumed liabilities is recorded as goodwill, which is not amortized but instead is evaluated for impairment at least annually. Pursuant to GAAP, an entity is allowed a reasonable period of time (not to exceed one year) to obtain the information necessary to identify and measure the fair value of the assets acquired and liabilities assumed in a business combination.

Impairment of Long-Lived Assets

We evaluate the carrying value of our long-lived assets (property, plant and equipment and amortizable intangible assets) for potential impairment when events and circumstances warrant such a review. A long-lived asset group is considered impaired when the anticipated undiscounted future cash flows from the use and eventual disposition of the asset group is less than its carrying value. We compare the carrying value of the long-lived asset to the estimated undiscounted future cash flows expected to be generated from that asset. Estimates of future net cash flows include estimating future volumes and margins, future operating costs and other estimates and assumptions consistent with our business plans. If we determine that an asset's unamortized cost may not be recoverable due to impairment, we may be required to reduce the carrying value and the subsequent useful life of the asset. Any such write-down of the value and unfavorable change in the useful life of a long-lived asset would increase costs and expenses at that time. Fair value calculations for long-lived assets and intangible assets contain uncertainties because it requires the Company to apply judgment and estimates concerning future cash flows, strategic plans, useful lives and market performance. The Company also applies judgment in the selection of a discount rate that reflects the risk inherent in the current business model.

Impairment of Goodwill

Goodwill is subject to at least an annual assessment for impairment. We perform our annual assessment of impairment during the fourth quarter of our fiscal year, and more frequently if circumstances warrant. Before employing detailed impairment testing methodologies, we may first evaluate the likelihood of impairment by considering qualitative factors relevant to the business, such as macroeconomic, industry, market or any other factors that have a significant bearing on fair value. If we first utilize a qualitative approach and



                                       43

Table of Contents

determine that it is more likely than not that goodwill is impaired, detailed testing methodologies are then applied. Otherwise, we conclude that no impairment has occurred. We may also choose to bypass a qualitative approach and opt instead to employ detailed testing methodologies, regardless of a possible more likely than not outcome. If we determine through the qualitative approach that detailed testing methodologies are required, or if the qualitative approach is bypassed, we compare the fair value of a reporting unit with its carrying amount under Step 1 of the impairment test. The determination of a reporting unit's fair value is predicated on our assumptions regarding the future economic prospects of the reporting unit. Such assumptions include (i) discrete financial forecasts for the assets contained within the reporting unit, which rely on our estimates of gross margins, (ii) long-term growth rates for cash flows beyond the discrete forecast period, (iii) appropriate discount rates and (iv) estimates of the cash flow multiples to apply in estimating the market value of our reporting units. If the carrying amount exceeds the fair value of a reporting unit, the Company performs Step 2 and compares the fair value of reporting unit goodwill with the carrying amount of that goodwill and recognizes an impairment charge for the amount by which the carrying amount exceeds the implied fair value? however, the loss recognized may not exceed the total amount of goodwill allocated to that reporting unit.

If future results are not consistent with our estimates, we could be exposed to future impairment losses that could be material to our results of operations. We monitor the markets for our products and services, in addition to the overall market, to determine if a triggering event occurs that would indicate that the fair value of a reporting unit is less than its carrying value.

Emerging Growth Company Status

We are an "emerging growth company," as defined in the JOBS Act, and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not "emerging growth companies." We may take advantage of these exemptions until we are no longer an "emerging growth company." Section 107 of the JOBS Act provides that an "emerging growth company" can take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards. We have elected to use the extended transition period for complying with new or revised accounting standards and as a result of this election, our financial statements may not be comparable to companies that comply with public company effective dates. We may take advantage of these exemptions up until the last day of the fiscal year following the fifth anniversary of our initial public offering or such earlier time that we are no longer an emerging growth company. We would cease to be an emerging growth company if we have more than $1.07 billion in annual revenue, we have more than $700.0 million in market value of our stock held by non-affiliates (and we have been a public company for at least 12 months and have filed one annual report on Form 10-K) or we issue more than $1.0 billion of non-convertible debt securities over a three-year period.
