RISK FACTORS

        Investing in our Class A common stock involves a high degree of risk. You should carefully consider the risks described below together with the other information set forth in this prospectus before making an investment decision. Our business, financial condition, cash flows or results of operations could be adversely affected by the occurrence of any of the risks discussed below. Additionally, the trading price of our Class A common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. The risks discussed below are not the only risks we face. We may experience additional risks and uncertainties not currently known to us or as a result of developments occurring in the future. Conditions that we currently deem to be immaterial may also adversely affect our business, financial condition, cash flows and results of operations.

Risks Related to Our Business

Our business depends on capital spending by the oil and gas industry in the United States and Western Canada, and reductions in capital spending could have a material adverse effect on our liquidity, results of operations and financial condition.

        Our business is directly affected by our customers' capital spending to explore for, develop and produce oil and gas in the United States and Canada. The significant decline in oil and gas prices that began in the fourth quarter of 2014 has caused a reduction in the exploration, development and production activities of most of our customers and their spending on our services. These cuts in spending have curtailed drilling programs as well as discretionary spending on well services, which has resulted in a reduction in the demand for our services as compared to activity levels in mid-2014, as well as the rates we can charge and the utilization of our assets. In addition, certain of our customers could become unable to pay their vendors and service providers, including us, as a result of the decline in commodity prices. Reduced discovery rates of new oil and gas reserves in our market areas as a result of decreased capital spending may also have a negative long-term impact on our business, even in an environment of stronger oil and gas prices, to the extent the reduced number of wells for us to service more than offsets increasing completion activity and intensity. Any of these conditions or events could adversely affect our operating results. If a recovery does not materialize and our customers fail to increase their capital spending, it could have a material adverse effect on our liquidity, results of operations and financial condition.

        Industry conditions are influenced by numerous factors over which we have no control, including:

•

the domestic and foreign economic conditions and supply of and demand for oil and gas;



•

the level of prices, and expectations about future prices, of oil and gas;



•

the level of global oil and gas exploration and production;



•

governmental regulations, including the policies of governments regarding the exploration for and production and development of their oil and gas reserves;



•

taxation and royalty charges;



•

political and economic conditions in oil and gas producing countries;



•

actions by the members of Organization of Petroleum Exporting Countries with respect to oil production levels and announcements of potential changes in such levels;



•

global weather conditions and natural disasters;



•

worldwide political, military and economic conditions;



•

the cost of producing and delivering oil and gas;

14

Table of Contents

•

the discovery rates of new oil and gas reserves;



•

activities by non-governmental organizations to limit certain sources of funding for the energy sector or restrict the exploration, development and production of oil and gas;



•

the ability of oil and gas producers to access capital;



•

technical advances affecting energy consumption; and



•

the potential acceleration of development of alternative fuels.

If oil prices or gas prices fail to increase or were to decline, the demand for our services could be adversely affected.

        The demand for our services is primarily determined by current and anticipated oil and gas prices and the related levels of capital spending and drilling activity in the areas in which we have operations. Volatility or weakness in oil prices or gas prices (or the perception that oil prices or gas prices will decrease) affects the spending patterns of our customers and may result in the drilling of fewer new wells or lower production spending on existing wells. This, in turn, could lead to lower demand for our services and may cause lower rates and lower utilization of our assets. If oil prices decline or gas prices continue to remain low or decline further, or if the recent increase in drilling activity reverses, the demand for our services and our results of operations could be materially and adversely affected.

        Prices for oil and gas historically have been extremely volatile and are expected to continue to be volatile. During the past six years, the posted West Texas Intermediate ("WTI") price for oil has ranged from a twelve-year low of $26.19 per Bbl in February 2016 to a high of $113.39 per Bbl in April 2011. The Henry Hub spot market price of gas has ranged from a low of $1.49 per MMBtu in March 2016 to a high of $7.51 per MMBtu in January 2010. During 2016, WTI prices ranged from $26.19 to $54.01 per Bbl and the Henry Hub spot market price of gas ranged from $1.49 to $3.80 per MMBtu. Oil prices began to recover in 2017 and reached a closing price of $63.82 per barrel on January 16, 2018, while the Henry Hub spot market price of gas was $5.46 per MMBtu on the same date. If the prices of oil and gas reverse their recent increases or decline, our operations, financial condition, cash flows and level of expenditures may be materially and adversely affected.

We have developed certain key infrastructure assets in the Bakken area of North Dakota, making us vulnerable to risks associated with conducting business in this region.

        We have secured three governmental permits that enable us to withdraw water from the Missouri River and Lake Sakakawea in North Dakota and have developed and expect to develop in the future significant water infrastructure related to these permits.

        Because of the key nature of these permits and water infrastructure within the Bakken, the success and profitability of our business may be disproportionately exposed to factors impacting this region. These factors include, among others: (i) the prices of, and associated costs to produce, crude oil and gas from wells in the Bakken and other regional supply and demand factors (including the generally higher cost nature of production in the Bakken compared to other major shale plays and the pricing differentials that exist in the Bakken because of transportation constraints); (ii) the amount of exploration, development and production activities of our Bakken customers and their spending on our services; (iii) our ability to keep and maintain our governmental water permits; (iv) the cost of operations and the prices we can charge our customers in this region; and (v) the availability of equipment, supplies, and labor. Although we currently have secured key permits for water in this region, if we were to lose our water rights for any reason, including termination by the government upon the occurrence of a material breach, including nonpayment and default in performance, or unexpected adverse environmental impacts, or our competitors were able to secure equivalent rights, our business could be materially harmed. In addition, our operations in the Bakken field may be

15

Table of Contents

adversely affected by severe weather events such as floods, blizzards, ice storms and tornadoes. For the nine months ended September 30, 2017 and 2016, our Bakken operations represented 11.3% and 8.3%, respectively, of our revenues. For the years ended December 31, 2016 and 2015, our Bakken operations represented 9.6% and 5.5%, respectively, of our revenues. The concentration of our water permits and significant infrastructure assets in North Dakota also increases our exposure to changes in local laws and regulations, including those designed to protect wildlife, and unexpected events that may occur in this region such as seismic events, industrial accidents or labor difficulties. Any of the risks described above could have an adverse effect on our financial condition, results of operations and cash flows.

Restrictions on the ability to procure water or changes in water sourcing requirements could decrease the demand for our water-related services.

        Our business includes water transfer for use in our customers' oil and gas E&P activities. Our access to the water we supply may be limited due to reasons such as prolonged drought or our inability to acquire or maintain water sourcing permits or other rights. In addition, some state and local governmental authorities have begun to monitor or restrict the use of water subject to their jurisdiction for hydraulic fracturing to ensure adequate local water supply. For instance, some states require E&P companies to report certain information regarding the water they use for hydraulic fracturing and to monitor the quality of groundwater surrounding some wells stimulated by hydraulic fracturing. In British Columbia, new regulations relating to the use of water under the Water Sustainability Act came into effect on February 29, 2016. This Act requires authorizations to be obtained to use groundwater for anything other than domestic use. The estimated 20,000 existing non-domestic groundwater users must be brought into the licensing scheme. In addition, anyone who diverts water must make beneficial use of that water, meaning they must use the water as efficiently as practicable, and for the purposes specified by the license or approval. In Alberta, the Alberta Energy Regulator ("AER") monitors water withdrawals, and may suspend water withdrawals during a low flow period or drought to protect the integrity of the water system. Further, in Alberta, the Water Conservation and Allocation Policy for Oilfield Injection may be expanded to include hydraulic fracturing activities under the proposed Water Conservation Policy for Upstream Oil and Gas Operations. If this policy is expanded to include hydraulic fracturing, licensees will come under increased scrutiny surrounding their water use. Groundwater and surface water available for licensing may be limited and in water-short areas of Alberta, projects may be delayed until new technology or alternative water sources become available to protect non-saline water resources. It is unclear if or when this policy may be implemented. Any such decrease in the availability of water, or demand for water services, could adversely affect our business and results of operations.

We have operated at a loss in the past, and there is no assurance of our profitability in the future.

        Historically, we have experienced periods of low demand for our services and have incurred operating losses. In the future, we may not be able to reduce our costs, increase our revenues or reduce our debt service obligations sufficient to achieve or maintain profitability and generate positive operating income. Under such circumstances, we may incur further operating losses and experience negative operating cash flow.

Fuel conservation measures could reduce demand for oil and natural gas which would in turn reduce the demand for our services.

        Fuel conservation measures, alternative fuel requirements and increasing consumer demand for alternatives to oil and natural gas could reduce demand for oil and natural gas. The impact of the changing demand for oil and natural gas may have a material adverse effect on our business, financial condition, prospects, results of operations and cash flows. Additionally, the increased competitiveness of alternative energy sources (such as wind, solar geothermal, tidal, fuel cells and biofuels) could reduce

16

Table of Contents

demand for hydrocarbons and therefore for our services, which would lead to a reduction in our revenues.

Failure to successfully combine our business with the business from Rockwater may adversely affect our future results.

        The consummation of the Rockwater Merger involves potential risks, including, without limitation, the failure to realize expected profitability, growth or accretion; the incurrence of liabilities or other compliance costs related to environmental or regulatory matters, including potential liabilities that may be imposed without regard to fault or the legality of conduct; diversion of management's attention from our existing businesses; and the incurrence of unanticipated liabilities and costs for which indemnification is unavailable or inadequate. If these risks or other unanticipated liabilities were to materialize, any desired benefits of the Rockwater Merger may not be fully realized, if at all, and our future financial performance and results of operations could be negatively impacted.

The growth of our business through acquisitions may expose us to various risks, including those relating to difficulties in identifying suitable, accretive acquisition opportunities and integrating businesses, assets and personnel, as well as difficulties in obtaining financing for targeted acquisitions and the potential for increased leverage or debt service requirements.

        As a component of our business strategy, we intend to pursue selected, accretive acquisitions of complementary assets, businesses and technologies. Acquisitions involve numerous risks, including:

•

unanticipated costs and assumption of liabilities and exposure to unforeseen liabilities of the acquired business, including but not limited to environmental liabilities;



•

difficulties in integrating the operations and assets of the acquired business and the acquired personnel;



•

limitations on our ability to properly assess and maintain an effective internal control environment over an acquired business;



•

potential losses of key employees and customers of the acquired business;



•

risks of entering markets in which we have limited prior experience; and



•

increases in our expenses and working capital requirements.

        In evaluating acquisitions, we generally prepare one or more financial cases based on a number of business, industry, economic, legal, regulatory and other assumptions applicable to the proposed transaction. Although we expect a reasonable basis will exist for those assumptions, the assumptions will generally involve current estimates of future conditions. Realization of many of the assumptions will be beyond our control. Moreover, the uncertainty and risk of inaccuracy associated with any financial projection will increase with the length of the forecasted period. Some acquisitions may not be accretive in the near term, and will be accretive in the long term only if we are able to timely and effectively integrate the underlying assets and such assets perform at or near the levels anticipated in our acquisition projections.

        The process of integrating an acquired business may involve unforeseen costs and delays or other operational, technical and financial difficulties and may require a significant amount time and resources. Our failure to incorporate the acquired business and assets into our existing operations successfully or to minimize any unforeseen operational difficulties could have a material adverse effect on our financial condition and results of operations. Furthermore, there is intense competition for acquisition opportunities in our industry. Competition for acquisitions may increase the cost of, or cause us to refrain from, completing acquisitions.

17

Table of Contents

        In addition, we may not have sufficient capital resources to complete any additional acquisitions. We may incur substantial indebtedness to finance future acquisitions and also may issue equity, debt or convertible securities in connection with such acquisitions. Debt service requirements could represent a significant burden on our results of operations and financial condition and the issuance of additional equity or convertible securities could be dilutive to our existing stockholders. Furthermore, we may not be able to obtain additional financing on satisfactory terms. Even if we have access to the necessary capital, we may be unable to continue to identify suitable acquisition opportunities, negotiate acceptable terms or successfully acquire identified targets.

Our Credit Agreement subjects us to various financial and other restrictive covenants. These restrictions may limit our operational or financial flexibility and could subject us to potential defaults under our Credit Agreement.

        Our Credit Agreement (as defined herein) subjects us to significant financial and other restrictive covenants, including restrictions on our ability to consolidate or merge with other companies, conduct asset sales, incur additional indebtedness, grant liens, issue guarantees, make investments, loans or advances, pay dividends and enter into certain transactions with affiliates.

        Our Credit Agreement contains certain financial covenants, including the maintenance of a fixed charge coverage ratio of at least 1.0 to 1.0 at any time availability under the Credit Agreement is less than the greater of (i) 10% of the lesser of (A) the maximum revolver amount and (B) the then-effective borrowing base and (ii) $15.0 million and continuing through and including the first day after such time that availability under the Credit Agreement has equaled or exceeded the greater of (i) 10% of the lesser of (A) the maximum revolver amount and (B) the then-effective borrowing base and (ii) $15.0 million for 60 consecutive calendar days. Our ability to comply with such financial condition tests can be affected by events beyond our control and we may not be able to do so. Our scheduled maturity date is November 1, 2022. In addition, the Credit Agreement restricts SES Holdings' and Select LLC's ability to make distributions on, or redeem or repurchase, its equity interests, except for certain distributions, including distributions of cash so long as, both at the time of the distribution and after giving effect to the distribution, no default exists under the Credit Agreement and either (a) excess availability at all times during the preceding 30 consecutive days, on a pro forma basis and after giving effect to such distribution, is not less than the greater of (1) 25% of the lesser of (A) the maximum revolver amount and (B) the then-effective borrowing base and (2) $37.5 million or (b) if SES Holdings' fixed charge coverage ratio is at least 1.0 to 1.0 on a pro forma basis, and excess availability at all times during the preceding 30 consecutive days, on a pro forma basis and after giving effect to such distribution, is not less than the greater of (1) 20% of the lesser of (A) the maximum revolver amount and (B) the then-effective borrowing base and (2) $30.0 million. For additional information regarding our Credit Agreement, please read "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Credit Agreement."

        If we are unable to remain in compliance with the covenants of our Credit Agreement, then the lenders may declare all amounts outstanding under the Credit Agreement to be immediately due and payable. Any such acceleration could have a material adverse effect on our financial condition and results of operations.

We may incur additional indebtedness or issue additional equity securities to execute our long-term growth strategy, which may reduce our profitability or result in significant dilution to our stockholders.

        Constructing and maintaining water infrastructure used in the oil and gas industry requires significant capital. We may require additional capital in the future to develop and construct water sourcing, transfer and other related infrastructure to execute our growth strategy. For the nine months ended September 30, 2017 and 2016, we incurred approximately $66.0 million and $28.6 million, respectively, in capital expenditures. For the year ended December 31, 2016 and 2015, we incurred

18

Table of Contents

approximately $36.3 million and $48.7 million, respectively, in capital expenditures. Historically, we have financed these investments through cash flows from operations, our IPO, external borrowings and capital contributions from the Legacy Owners and Contributing Legacy Owners. These sources of capital may not be available to us in the future. If we are unable to fund capital expenditures for any reason, we may not be able to capture available growth opportunities and any such failure could have a material adverse effect on our results of operations and financial condition. If we incur additional indebtedness or issue additional equity securities, our profitability may be reduced and our stockholders may experience significant dilution.

Significant price volatility or interruptions in supply of our raw materials may result in increased costs that we may be unable to pass on to our customers, which could reduce profitability.

        We purchase a substantial portion of our raw materials from third-party suppliers and the cost of these raw materials represents a substantial portion of our operating expenses. The prices of the raw materials that we purchase from third parties are cyclical and volatile. Our supply agreements provide us only limited protection against price volatility as they are entered into either on a short-term basis or are longer-term volume contracts, which provide for market-based pricing re-negotiated several times per year. While we attempt to match cost increases with corresponding product price increases, we are not always able to raise product prices immediately or at all. Timing differences between raw material prices, which may change daily, and contract product prices, which in many cases are negotiated only monthly or less often, have had and may continue to have a negative effect on our cash flow. Any cost increase that we are not able to pass on to our customers could have a material adverse effect on our business, results of operations, financial condition and liquidity.

        There are several raw materials for which there are only a limited number of suppliers or a single supplier. To mitigate potential supply constraints, we enter into supply agreements with particular suppliers, evaluate alternative sources of supply and evaluate alternative technologies to avoid reliance on limited or sole-source suppliers. Where supply relationships are concentrated, particular attention is paid by the parties to ensure strategic intentions are aligned to facilitate long-term planning. If certain of our suppliers are unable to meet their obligations under present supply agreements, we may be forced to pay higher prices to obtain the necessary raw materials from other sources and we may not be able to increase prices for our finished products to recoup the higher raw materials costs. Any interruption in the supply of raw materials could increase our costs or decrease our revenue, which could reduce our cash flow. The inability of a supplier to meet our raw material needs could have a material adverse effect on our financial statements and results of operations.

        The number of sources for and availability of certain raw materials is also specific to the particular geographical region in which a facility is located. Political and economic instability in the countries from which we purchase our raw material supplies could adversely affect their availability. In addition, if raw materials become unavailable within a geographic area from which they are now sourced, then we may not be able to obtain suitable or cost effective substitutes. We may also experience higher operating costs such as energy or transportation costs, which could affect our profitability. We may not always be able to increase our selling prices to offset the impact of any higher productions costs or reduced production levels, which could reduce our earnings and decrease our liquidity.

We may be subject to claims for personal injury and property damage, which could materially adversely affect our financial condition, results of operations and cash available for distribution.

        We operate with most of our customers under master service agreements ("MSAs"). We endeavor to allocate potential liabilities and risks between the parties in the MSAs. Generally, under our MSAs, including those relating to our services, we assume responsibility for, including control and removal of, pollution or contamination which originates above surface and originates from our equipment or services. Our customer generally assumes responsibility for, including control and removal of, all other

19

Table of Contents

pollution or contamination which may occur during operations, including that which may result from seepage or any other uncontrolled flow of drilling fluids. We may have liability in such cases if we are negligent or commit willful acts. Generally, our customers also agree to indemnify us against claims arising from their employees' personal injury or death to the extent that, in the case of our operations, their employees are injured or their properties are damaged by such operations, unless resulting from our gross negligence or willful misconduct. Similarly, we generally agree to indemnify our customers for liabilities arising from personal injury to or death of any of our employees, unless resulting from gross negligence or willful misconduct of the customer. In addition, our customers generally agree to indemnify us for loss or destruction of customer-owned property or equipment and in turn, we agree to indemnify our customers for loss or destruction of property or equipment we own. Losses due to catastrophic events, such as blowouts, are generally the responsibility of the customer. However, despite this general allocation of risk, we might not succeed in enforcing such contractual allocation, might incur an unforeseen liability falling outside the scope of such allocation or may be required to enter into an MSA with terms that vary from the above allocations of risk. As a result, we may incur substantial losses which could materially and adversely affect our financial condition, results of operations and cash available for distribution.

We are subject to environmental and occupational health and safety laws and regulations that may expose us to significant liabilities for penalties, damages or costs of remediation or compliance.

        Our operations and the operations of our customers are subject to federal, provincial, state and local laws and regulations in the United States and Western Canada relating to protection of natural resources and the environment, health and safety aspects of our operations and waste management, including the transportation and disposal of waste and other materials. These laws and regulations may impose numerous obligations on our operations and the operations of our customers, including the acquisition of permits to take fresh water from surface and underground sources, construct pipelines or containment facilities, drill wells or conduct other regulated activities, the incurrence of capital expenditures to mitigate or prevent releases of materials from our facilities or from customer locations where we are providing services, the imposition of substantial liabilities for pollution resulting from our operations, and the application of specific health and safety criteria addressing worker protection. Any failure on our part or the part of our customers to comply with these laws and regulations could result in restrictions on operations, assessment of administrative, civil and criminal penalties, revocation of permits and issuance of corrective action orders requiring the performance of investigatory, remedial or curative activities.

        Our business activities present risks of incurring significant environmental costs and liabilities, including costs and liabilities resulting from our handling of oilfield and other wastes, because of air emissions and wastewater discharges related to our operations, and due to historical oilfield industry operations and waste disposal practices. Our businesses include the operation of oilfield waste disposal injection wells that pose risks of environmental liability, including leakage from the wells to surface or subsurface soils, surface water or groundwater. In addition, private parties, including the owners of properties upon which we perform services and facilities where our wastes are taken for reclamation or disposal, also may have the right to pursue legal actions to enforce compliance as well as to seek damages for non-compliance with environmental laws and regulations or for personal injury or property or natural resource damages. Some environmental laws and regulations may impose strict liability, which means that in some situations we could be exposed to liability as a result of our conduct that was lawful at the time it occurred or the conduct of, or conditions caused by, prior operators or other third parties. Remedial costs and other damages arising as a result of environmental laws and costs associated with changes in environmental laws and regulations could be substantial and could have a material adverse effect on our liquidity, consolidated results of operations and consolidated financial condition.

        Laws and regulations protecting the environment generally have become more stringent in recent years and are expected to continue to do so, which could lead to material increases in costs for future environmental compliance and remediation. Changes in existing laws or regulations, or the adoption of new laws or regulations, could delay or curtail exploratory or developmental drilling for oil and gas and could limit well servicing opportunities. We may not be able to recover some or any of our costs of compliance with these laws and regulations from insurance.

Unsatisfactory safety performance may negatively affect our customer relationships and, to the extent we fail to retain existing customers or attract new customers, adversely impact our revenues.

        Our ability to retain existing customers and attract new business is dependent on many factors, including our ability to demonstrate that we can reliably and safely operate our business and stay current on constantly changing rules, regulations, training and laws. Existing and potential customers consider the safety record of their service providers to be of high importance in their decision to engage third-party servicers. If one or more accidents were to occur at one of our operating sites, the affected customer may seek to terminate or cancel its use of our facilities or services and may be less likely to continue to use our services, which could cause us to lose substantial revenues. Further, our ability to attract new customers may be impaired if they elect not to purchase our third-party services because they view our safety record as unacceptable. In addition, it is possible that we will experience numerous or particularly severe accidents in the future, causing our safety record to deteriorate. This may be more likely as we continue to grow, if we experience high employee turnover or labor shortage, or add inexperienced personnel.

Federal, state, provincial and local legislative and regulatory initiatives in the United States and Western Canada related to hydraulic fracturing could result in operating restrictions or delays in the drilling and completion of oil and gas wells that may reduce demand for our services and could have a material adverse effect on our liquidity, consolidated results of operations and consolidated financial condition.

        Hydraulic fracturing is an important and common practice that is used to stimulate production of hydrocarbons from dense subsurface rock formations. The process involves the injection of water, sand or other proppants and chemical additives under pressure into targeted geological formations to fracture the surrounding rock and stimulate production. In the United States, hydraulic fracturing is currently generally exempt from regulation under the U.S. Safe Drinking Water Act's (the "SDWA") Underground Injection Control ("UIC") program and is typically regulated by state oil and gas commissions or similar agencies.

        However, several federal agencies in the United States have asserted regulatory authority over certain aspects of the process. For example, in 2014, the U.S. Environmental Protection Agency (the "EPA") asserted regulatory authority pursuant to the SDWA's UIC program over hydraulic fracturing activities involving the use of diesel and issued guidance covering such activities. Additionally, in June 2016, the EPA published an effluent limit guideline final rule prohibiting the discharge of wastewater from onshore unconventional oil and gas extraction facilities to publicly owned wastewater treatment plants and, in 2014, issued a prepublication of its Advance Notice of Proposed Rulemaking regarding the Toxic Substances Control Act ("TSCA") reporting of the chemical substances and mixtures used in hydraulic fracturing. Also, the Bureau of Land Management ("BLM") published a final rule in 2015 that established new or more stringent standards relating to hydraulic fracturing on federal and American Indian lands. This rule was struck down by a Wyoming federal judge, but, in June 2016, the decision was appealed by the BLM to the U.S. Circuit Court of Appeals for the Tenth Circuit. However, following the issuance of a presidential executive order to review rules related to the energy industry, in July 2017, the BLM published a proposed rule to rescind the 2015 final rule. In September 2017, the Tenth Circuit issued a ruling to vacate the Wyoming trial court decision and dismiss the lawsuit challenging the 2015 rule in light of the BLM's proposed rulemaking. On December 29, 2017,

21

Table of Contents

the BLM published a final rule rescinding the March 2015 final rule. From time to time, legislation has been introduced, but not enacted, in Congress to provide for federal regulation of hydraulic fracturing and to require disclosure of the chemicals used in the fracturing process. In the event that new federal restrictions on the hydraulic-fracturing process are adopted in areas where we or our customers conduct business, we or our customers may incur additional costs or permitting requirements to comply with such federal requirements that may be significant in nature and, in the case of our customers, could experience added delays or curtailment in the pursuit of exploration, development, or production activities, which would in turn reduce the demand for our services.

        Moreover, some states and local governments have adopted, and other governmental entities are considering adopting, regulations that could impose more stringent permitting, disclosure and well-construction requirements on hydraulic fracturing operations, including states where we or our customers operate. For example, Texas, Oklahoma, California, Ohio, Pennsylvania and North Dakota, among others, have adopted regulations that impose new or more stringent permitting, disclosure, disposal and well construction requirements on hydraulic fracturing operations. States could also elect to prohibit high volume hydraulic fracturing altogether, following the approach taken by the State of New York. In addition, in light of concerns about seismic activity being triggered by the injection of produced waste waters into underground disposal wells, certain regulators are also considering additional requirements related to seismic safety for hydraulic fracturing activities. For example, the Oklahoma Corporation Commission released well completion seismicity guidelines in December 2016 for operators in the SCOOP and STACK that call for hydraulic fracturing operations to be suspended following earthquakes of certain magnitudes in the vicinity. In addition, the Oklahoma Corporation Commission's Oil and Gas Conservation Division issued an order in February 2017 limiting future increases in the volume of oil and natural gas wastewater injected into the ground in an effort to reduce the number of earthquakes in the state, and imposed further reductions in the Edmonds area of the state in August 2017. In addition to state laws, local land use restrictions, such as city ordinances, may restrict drilling in general and/or hydraulic fracturing in particular, as certain local governments in California have done. Other states, such as Texas, Oklahoma and Ohio have taken steps to limit the authority of local governments to regulate oil and gas development.

        In December 2016, the EPA released its final report on the potential impacts of hydraulic fracturing on drinking water resources. The final report concluded that "water cycle" activities associated with hydraulic fracturing may impact drinking water resources "under some circumstances," noting that the following hydraulic fracturing water cycle activities and local- or regional-scale factors are more likely than others to result in more frequent or more severe impacts: water withdrawals for fracturing in times or areas of low water availability; surface spills during the management of fracturing fluids, chemicals or produced water; injection of fracturing fluids into wells with inadequate mechanical integrity; injection of fracturing fluids directly into groundwater resources; discharge of inadequately treated fracturing wastewater to surface waters; and disposal or storage of fracturing wastewater in unlined pits.

        While hydraulic fracturing in Alberta and British Columbia, Canada has been occurring for decades, due to concerns over environmental impacts including water usage, wastewater disposal and contamination, and induced seismicity, the AER in Alberta and the British Columbia Oil and Gas Commission ("BCOGC") in British Columbia continue to conduct ongoing review of rules and regulations of the industry. The AER has moved to require water use measurement and sourcing details for all fractured wells in Alberta, fracture fluid chemical disclosure, limited trade secret protection and prescribed setbacks for shallow fracturing near water wells.

        Increased regulation and attention given to the hydraulic fracturing process could lead to greater opposition to oil and gas production activities using hydraulic fracturing techniques. Additional legislation or regulation could also lead to operational delays or increased operating costs for our customers in the production of oil and gas, including from the developing shale plays, or could make it

22

Table of Contents

more difficult to perform hydraulic fracturing. The adoption of any federal, state or local laws or the implementation of regulations regarding hydraulic fracturing could potentially cause a decrease in the completion of new oil and gas wells and an associated decrease in demand for our services and increased compliance costs and time, which could have a material adverse effect on our liquidity, consolidated results of operations, and consolidated financial condition.

Climate change legislation or regulations in the United States and Western Canada restricting or regulating emissions of greenhouse gases could result in increased operating costs and reduced demand for our field services.

        In the United States, in response to findings that emissions of carbon dioxide, methane and other greenhouse gases ("GHGs") present an endangerment to public health and the environment, the EPA has adopted regulations under existing provisions of the U.S. Clean Air Act ("CAA") that, among other things, establish Prevention of Significant Deterioration ("PSD") construction and Title V operating permit reviews for certain large stationary sources that emit certain principal, or "criteria," pollutants. Facilities required to obtain PSD permits for their GHG emissions also will be required to meet "best available control technology" standards. In addition, the EPA has adopted rules requiring the monitoring and annual reporting of GHG emissions from oil and gas production, processing, transmission and storage facilities in the United States.

        The U.S. Congress has from time to time considered legislation to reduce emissions of GHGs but there has not been significant activity in the form of adopted legislation to reduce GHG emissions at the federal level in recent years. In the absence of such federal climate legislation, a number of state and regional efforts have emerged that are aimed at tracking and/or reducing GHG emissions through the completion of GHG emissions inventories and by means of cap and trade programs that typically require major sources of GHG emissions to acquire and surrender emission allowances in return for emitting those GHGs. The EPA has also developed strategies for the reduction of methane emissions, including emissions from the oil and gas industry. For example, in June 2016, the EPA published New Source Performance Standards ("NSPS"), known as Subpart OOOOa, that require certain new, modified or reconstructed facilities in the oil and natural gas sector to reduce methane gas and volatile organic compound emissions. These Subpart OOOOa standards will expand previously issued NSPS published by the EPA in 2012, and known as Subpart OOOO, by using certain equipment-specific emissions control practices. However, the Quad OOOOa standards have been subject to attempts by the EPA to stay portions of those standards, and the agency proposed rulemaking in June 2017 to stay the requirements for a period of two years and revisit implementation of Subpart OOOOa in its entirety. The EPA has not yet published a final rule, and, as a result of these developments, EPA's 2016 standards are currently in effect, but future implementation of the 2016 standards is uncertain at this time. Because of the long-term trend toward increasing regulation, however, future federal GHG regulations of the oil and natural gas industry remain a possibility. Furthermore, in June 2017, the BLM published a final rule that established, among other things, requirements to reduce methane emissions arising from venting, flaring and leaking from oil and gas production activities on onshore federal and American Indian lands. However, on December 8, 2017, the BLM published a final rule to temporarily suspend or delay certain requirements contained in the November 2016 final rule until January 17, 2019, including those requirements relating to venting, flaring and leakage from oil and gas production activities. That suspension is now being challenged in court, and uncertainty exists with respect to future implementation of the rule. However, given the long-term trend towards increasing regulation, future federal GHG regulations of the oil and gas industry remain a possibility. Furthermore, the EPA passed a new rule, known as the Clean Power Plan, to limit GHGs from power plants. While the U.S. Supreme Court issued a stay in February 2016, preventing implementation during the pendency of legal challenges to the rule in court, should the stay be lifted and legal challenges prove unsuccessful, then it could reduce demand for the oil and gas our customers produce, which could reduce the demand for our services, depending on the methods used to implement the

23

Table of Contents

rule. On October 10, 2017, the EPA issued a proposed rulemaking to repeal the Clean Power Plan. The public comment period on the proposed rulemaking ended on December 15, 2017. Additionally, in December 2015, the United States joined the international community at the 21st Conference of the Parties of the United Nations Framework Convention on Climate Change in Paris, France that proposed an agreement, requiring member countries to review and "represent a progression" in their intended nationally determined contributions, which set GHG emission reduction goals every five years beginning in 2020. This agreement was signed by the United States in April 2016 and entered into force in November 2016. The United States is one of over 120 nations having ratified or otherwise consented to the agreement; however this agreement does not create any binding obligations for nations to limit their GHG emissions, but rather includes pledges to voluntarily limit or reduce future emissions. In June 2017, President Trump announced that the United States intends to withdraw from the Paris Agreement and to seek negotiations either to reenter the Paris Agreement on different terms or a separate agreement. In August 2017, the U.S. Department of State officially informed the United Nations of the intent of the United States to withdraw from the Paris Agreement. The Paris Agreement provides for a four-year exit process beginning when it took effect in November 2016, which would result in an effective exit date of November 2020. The United States' adherence to the exit process and/or the terms on which the United States may re-enter the Paris Agreement or a separately negotiated agreement are unclear at this time.

        In Canada, significant climate change initiatives are ongoing at both the provincial and federal levels. Prime Minister Justin Trudeau announced in late 2016 that provinces have until 2018 to impose a carbon pricing scheme or else a federally mandated price will be imposed. The price would be set at $10 per tonne of carbon dioxide in 2018, rising $10 each year, to $50 per tonne by 2022. The provincial government in Alberta, as of January 1, 2017, has implemented a carbon tax at a rate of $20 per tonne in 2017, rising to $30 per tonne in 2018. While British Columbia adopted a carbon tax in 2008, with the final scheduled increase occurring in 2012 at $30 per tonne, under the federal carbon tax, British Columbia's carbon tax will be required to increase in 2021. In addition, Canada signed the Paris Agreement in April 2016, which could lead to additional regulation of GHG emissions.

        Although it is not possible at this time to predict how new laws or regulations in the United States or Canada or any legal requirements imposed by the Paris Agreement on the United States, should it not withdraw from the agreement, or Canada that may be adopted or issued to address GHG emissions would impact our business, any such future laws, regulations or other legal requirements imposing reporting or permitting obligations on, or limiting emissions of GHGs from, our or our customers' equipment and operations could require us or our customers to incur costs to reduce emissions of GHGs associated with operations as well as delays or restrictions in the ability to permit GHG emissions from new or modified sources. In addition, substantial limitations on GHG emissions could adversely affect demand for the oil and gas our customers produce, which could reduce demand for our services. Moreover, activists concerned about the potential effects of climate change have directed their attention at sources of funding for fossil-fuel energy companies, which has resulted in certain financial institutions, funds and other sources of capital restricting or eliminating their investment in oil and natural gas activities. Ultimately, this could make it more difficult to secure funding for exploration and production activities. Notwithstanding potential risks related to climate change, the International Energy Agency estimates that global energy demand will continue to rise and will not peak until after 2040 and that oil and gas will continue to represent a substantial percentage of global energy use over that time.

        Finally, it should be noted that increasing concentrations of GHGs in the Earth's atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, floods, droughts and other climatic events. If any such effects were to occur, they could have an adverse effect on our and our customers' operations.

Legislation or regulatory initiatives intended to address seismic activity associated with oilfield disposal wells could restrict our ability to dispose of produced water gathered from our customers and, accordingly, could have a material adverse effect on our business.

        We dispose of wastewater gathered from oil and gas producing customers that results from their drilling and production operations pursuant to permits issued to us by government authorities overseeing such disposal activities. While these permits are issued pursuant to existing laws and regulations, these legal requirements are subject to change, which could result in the imposition of more stringent permitting or operating constraints or new monitoring and reporting requirements owing to, among other things, concerns of the public or governmental authorities regarding such disposal activities.

        One such concern relates to recent seismic events in the United States near underground disposal wells used for the disposal by injection of produced water resulting from oil and gas activities. Developing research suggests that the link between seismic activity and wastewater disposal may vary by region, and that only a very small fraction of the tens of thousands of injection wells have been suspected to be, or have been, the likely cause of induced seismicity. In March 2016, the United States Geological Survey identified six states with the most significant hazards from induced seismicity, including Oklahoma, Kansas, Texas, Colorado, New Mexico and Arkansas. The United States Geological Survey also noted the potential for induced seismicity in Ohio and Alabama. In response to concerns regarding induced seismicity, regulators in some states have imposed, or are considering imposing, additional requirements in the permitting of produced water disposal wells or otherwise to assess any relationship between seismicity and the use of such wells. For example, Oklahoma issued new rules for wastewater disposal wells in 2014 that imposed certain permitting and operating restrictions and reporting requirements on disposal wells in proximity to faults and also, from time to time, has developed and implemented plans directing certain wells where seismic incidents have occurred to restrict or suspend disposal well operations. In particular, the Oklahoma Corporation Commission released well completion seismicity guidelines in December 2016 for operators in the SCOOP and STACK that call for hydraulic fracturing operations to be suspended following earthquakes of certain magnitudes in the vicinity. In addition, the Oklahoma Corporation Commission's Oil and Gas Conservation Division issued an order in February 2017 limiting future increases in the volume of oil and natural gas wastewater injected into the ground in an effort to reduce the number of earthquakes in the state and imposed further reductions in the Edmonds area of the state in August 2017. The Texas Railroad Commission adopted similar rules in 2014. In addition, ongoing lawsuits allege that disposal well operations have caused damage to neighboring properties or otherwise violated state and federal rules regulating waste disposal. These developments could result in additional regulation and restrictions on the use of injection wells. Increased regulation and attention given to induced seismicity could lead to greater opposition to oil and gas activities utilizing injection wells for waste disposal. The adoption and implementation of any new laws, regulations or directives that restrict our ability to dispose of wastewater gathered from our customers by limiting, volumes, disposal rates, disposal well locations or otherwise, or requiring us to shut down disposal wells, could have a material adverse effect on our business, financial condition and results of operations.

The Endangered Species Act and Migratory Bird Treaty Act in the United States and similar legislation applicable in Western Canada govern both our and our oil and gas producing customers' operations and additional restrictions may be imposed in the future, which constraints could have an adverse impact on our ability to expand some of our existing operations or limit our customers' ability to develop new oil and gas wells.

        In the United States, the Endangered Species Act (the "ESA") restricts activities that may affect endangered or threatened species or their habitats. Similar protections are offered to migratory birds under the Migratory Bird Treaty Act (the "MBTA"). To the extent species that are listed under the

25

Table of Contents

ESA or similar state laws, or are protected under the MBTA, live in the areas where we or our oil and gas producing customers' operate, both our and our customers' abilities to conduct or expand operations and construct facilities could be limited or be forced to incur material additional costs. Moreover, our customers' drilling activities may be delayed, restricted or precluded in protected habitat areas or during certain seasons, such as breeding and nesting seasons. Some of our operations and the operations of our customers are located in areas that are designated as habitats for protected species.

        In addition, as a result of one or more settlements entered into by the U.S. Fish & Wildlife Service (the "FWS"), the agency is required to make a determination on the listing of numerous other species as endangered or threatened under the ESA by the end of the FWS' 2017 fiscal year. The designation of previously unidentified endangered or threatened species could indirectly cause us to incur additional costs, cause our or our oil and gas producing customers' operations to become subject to operating restrictions or bans, and limit future development activity in affected areas. The FWS and similar state agencies may designate critical or suitable habitat areas that they believe are necessary for the survival of threatened or endangered species. Such a designation could materially restrict use of or access to federal, state and private lands.

        In Canada, the Migratory Birds Convention Act ("MBCA") prohibits the release of substances that can harm migratory birds in waters used by them, and gives the federal government the authority to develop regulations to protect migratory birds, and their habitats, including nests. Oil and gas development projects must comply with provisions of the MBCA, as well as the federal Species at Risk Act. Alberta and British Columbia each have a provincial Wildlife Act, which impose restrictions to prevent wildlife species from disappearing that could impact oil and gas operations and reduce demand for our services.

Our chemical products are subject to stringent chemical control laws that could result in increased costs on our business.

        We are subject to a wide array of laws and regulations governing chemicals, including the regulation of chemical substances and inventories, such as the TSCA in the United States and the Canadian Environmental Protection Act in Canada. These laws and regulations change frequently, and have the potential to limit or ban altogether the types of chemicals we may use in our products, as well as result in increased costs related to testing, storing, and transporting our products prior to providing them to our customers. For example, in June 2016, President Obama signed into law the Frank R. Lautenberg Chemical Safety for the 21st Century Act (the "Lautenberg Act"), which substantially revised TSCA. Among other items, the Lautenberg Act eliminated the cost-benefit approach to analyzing chemical safety concerns with a health-based safety standard and requires all chemicals in commerce, including those "grandfathered" under TSCA, to undergo a safety review. The Lautenberg Act also requires safety findings before a new chemical can enter the market. Although it is not possible at this time to predict how EPA will implement and interpret the new provisions of the Lautenberg Act, or how legislation or new regulations that may be adopted pursuant to these regulatory and legislative efforts would impact our business, any new restrictions on the development of new products, increases in regulation, or disclosure of confidential, competitive information could have an adverse effect on our operations and our cost of doing business.

        Furthermore, governmental, regulatory and societal demands for increasing levels of product safety and environmental protection could result in increased pressure for more stringent regulatory control with respect to the chemical industry. In addition, these concerns could influence public perceptions regarding our products and operations, the viability of certain products, our reputation, the cost to comply with regulations, and the ability to attract and retain employees. Moreover, changes in environmental, health and safety regulations could inhibit or interrupt our operations, or require us to modify our facilities or operations. Accordingly, environmental or regulatory matters may cause us to incur significant unanticipated losses, costs or liabilities, which could reduce our profitability.

Disruptions in production at our chemical manufacturing facilities may have a material adverse impact on our business, results of operations and/or financial condition.

        Chemical manufacturing facilities in our industry are subject to outages and other disruptions. Any serious disruption at any of our facilities could impair our ability to use our facilities and have a material adverse impact on our revenue and increase our costs and expenses. Alternative facilities with sufficient capacity may not be available, may cost substantially more or may take a significant time to increase production or qualify with our customers, any of which could negatively impact our business, results of operations and/or financial condition. Long-term production disruptions may cause our customers to seek alternative supply which could further adversely affect our profitability.

        Unplanned production disruptions may occur for external reasons including natural disasters, weather, disease, strikes, transportation interruption, government regulation, political unrest or terrorism, or internal reasons, such as fire, unplanned maintenance or other manufacturing problems. Any such production disruption could have a material impact on our operations, operating results and financial condition.

        In addition, we rely on a number of vendors, suppliers, and in some cases sole-source suppliers, service providers, toll manufacturers and collaborations with other industry participants to provide us with chemicals, feedstocks and other raw materials, along with energy sources and, in certain cases, facilities that we need to operate our business. If the business of these third parties is disrupted, some of these companies could be forced to reduce their output, shut down their operations or file for bankruptcy protection. If this were to occur, it could adversely affect their ability to provide us with the raw materials, energy sources or facilities that we need, which could materially disrupt our operations, including the production of certain of our chemical products. Moreover, it could be difficult to find replacements for certain of our business partners without incurring significant delays or cost increases. All of these risks could have a material adverse effect on our business, results of operations, financial condition and liquidity.

        While we maintain business recovery plans that are intended to allow us to recover from natural disasters or other events that could disrupt our business, we cannot provide assurances that our plans would fully protect us from the effects of all such disasters or from events that might increase in frequency or intensity due to climate change. In addition, insurance may not adequately compensate us for any losses incurred as a result of natural or other disasters. In areas prone to frequent natural or other disasters, insurance may become increasingly expensive or not available at all.

We face significant competition that may cause us to lose market share and could negatively affect our ability to expand our operations, and we may be unable to compete effectively with larger companies.

        The water solutions business is highly competitive. Some of our competitors have a similarly broad geographic scope, as well as greater financial and other resources than we do, while others focus on specific basins only and may have local competitive cost efficiencies as a result. Additionally, there may be new companies that enter the water solutions business or our existing and potential customers may develop their own water solutions businesses. Our ability to maintain current revenue and cash flows, and our ability to expand our operations, could be adversely affected by the activities of our competitors and our customers. If our competitors substantially increase the resources they devote to the development and marketing of competitive services or substantially decrease the prices at which they offer their services, we may be unable to effectively compete. If our existing and potential customers develop their own water solutions businesses, we may not be able to effectively replace that revenue. All of these competitive pressures could have a material adverse effect on our business, results of operations and financial condition.

        The oil and gas industry is intensely competitive, and we compete with other companies that have greater resources than us. Many of our larger competitors provide a broader base of services on a

27

Table of Contents

regional, national or worldwide basis. These companies may have a greater ability to continue oilfield service activities during periods of low commodity prices, to contract for equipment, to secure trained personnel, to secure contracts and permits and to absorb the burden of present and future federal, state, provincial, local and other laws and regulations (as applicable). Any inability to compete effectively with larger companies could have a material adverse impact on our financial condition and results of operations.

We may be unable to implement price increases or maintain existing prices on our core services.

        We periodically seek to increase the prices on our services to offset rising costs and to generate higher returns for our stockholders. However, we operate in a very competitive industry and as a result, we are not always successful in raising, or maintaining, our existing prices. Additionally, during periods of increased market demand, a significant amount of new service capacity, including new well service rigs, fluid hauling trucks and coiled tubing units, may enter the market, which also puts pressure on the pricing of our services and limits our ability to increase prices.

        Even when we are able to increase our prices, we may not be able to do so at a rate that is sufficient to offset such rising costs. In periods of high demand for oilfield services, a tighter labor market may result in higher labor costs. During such periods, our labor costs could increase at a greater rate than our ability to raise prices for our services. Also, we may not be able to successfully increase prices without adversely affecting our activity levels. The inability to maintain our pricing and to increase our pricing as costs increase could have a material adverse effect on our business, financial position and results of operations.

Our operations involve risks that may increase our operating costs, which could reduce our profitability.

        Although we take precautions to enhance the safety of our operations and minimize the risk of disruptions, our operations are subject to hazards inherent in the manufacturing and marketing of chemical and other products. These hazards include: chemical spills, pipeline leaks and ruptures, storage tank leaks, discharges or releases of toxic or hazardous substances or gases and other hazards incident to the manufacturing, processing, handling, transportation and storage of hazardous chemicals. We are also potentially subject to other hazards, including natural disasters and severe weather; explosions and fires; transportation problems, including interruptions, spills and leaks; mechanical failures; unscheduled downtimes; labor difficulties; remediation complications; and other risks. Many potential hazards can cause bodily injury and loss of life, severe damage to or destruction of property and equipment and environmental damage, and may result in suspension of operations and the imposition of civil or criminal penalties and liabilities. Furthermore, we are subject to present and future claims with respect to workplace exposure, exposure of contractors on our premises as well as other persons located nearby, workers' compensation and other matters.

        We maintain property, business interruption, products liability and casualty insurance policies which we believe are in accordance with customary industry practices, as well as insurance policies covering other types of risks, including pollution legal liability insurance, but we are not fully insured against all potential hazards and risks incident to our business. Each of these insurance policies is subject to customary exclusions, deductibles and coverage limits, in accordance with industry standards and practices. As a result of market conditions, premiums and deductibles for certain insurance policies can increase substantially and, in some instances, certain insurance may become unavailable or available only for reduced amounts of coverage. If we were to incur a significant liability for which we were not fully insured, it could have a material adverse effect on our business, results of operations, financial condition and liquidity.

28

Table of Contents

        In addition, we are subject to various claims and litigation in the ordinary course of business. We are a party to various pending lawsuits and proceedings. For more information, see "Business—Legal Proceedings" below.

Our success depends on key members of our management, the loss of any of whom could disrupt our business operations.

        We depend to a large extent on the services of some of our executive officers. The loss of the services of one or more of our key executives could increase our exposure to the other risks described in this "Risk Factors" section. We do not maintain key man insurance on any of our personnel other than John D. Schmitz, our Executive Chairman.

Our industry has experienced a high rate of employee turnover. Any difficulty we experience replacing or adding personnel could have a material adverse effect on our liquidity, results of operations and financial condition.

        We are dependent upon the available labor pool of skilled employees and may not be able to find enough skilled labor to meet our needs, which could have a negative effect on our growth. We are also subject to the Fair Labor Standards Act, which governs such matters as minimum wage, overtime and other working conditions. Our services require skilled workers who can perform physically demanding work. As a result of our industry volatility, including the recent and pronounced decline in drilling activity, as well as the demanding nature of the work, many workers have left the oilfield services section to pursue employment in different fields. If we are unable to retain or meet growing demand for skilled technical personnel, our operating results and our ability to execute our growth strategies may be adversely affected.

Delays or restrictions in obtaining permits by us for our operations or by our customers for their operations could impair our business.

        In most states, our operations and the operations of our oil and gas producing customers require permits from one or more governmental agencies in order to perform drilling and completion activities, secure water rights, construct impoundments tanks and operate pipelines or trucking services. In the United States, such permits are typically issued by state agencies, but federal and local governmental permits may also be required. Similarly, in Canada, permits are generally issued by provincial agencies. However, federal permits are required for certain activities, such as where a project occurs on lands under federal jurisdiction. Where projects occur on unoccupied Crown lands, treaty lands or in proximity to Reserves, project proponents may face significant delays due to challenges from First Nations people because First Nations have constitutionally guaranteed rights to hunt, trap and fish. Project proponents must conduct adequate consultation with affected First Nations, and projects may encounter lengthy delays if court challenges are made in regards to inadequate consultation. The requirements for such permits vary depending on the location where such drilling and completion, and pipeline and gathering, activities will be conducted. As with all governmental permitting processes, there is a degree of uncertainty as to whether a permit will be granted, the time it will take for a permit to be issued, the conditions that may be imposed in connection with the granting of the permit and whether the permit may be terminated. In addition, some of our customers' drilling and completion activities may take place on federal land or Native American lands, requiring leases and other approvals from the federal government or Native American tribes to conduct such drilling and completion activities. Under certain circumstances, federal agencies may cancel proposed leases for federal lands and refuse to grant or delay required approvals. Therefore, our customers' operations in certain areas of the United States may be interrupted or suspended for varying lengths of time, causing a loss of revenue to us and adversely affecting our results of operations in support of those customers.

In the future we may face increased obligations relating to the closing of our wastewater disposal facilities and may be required to provide an increased level of financial assurance to guarantee that the appropriate closure activities will occur for a wastewater disposal facility.

        Obtaining a permit to own or operate wastewater disposal facilities generally requires us to establish performance bonds, letters of credit or other forms of financial assurance to address remediation and closure obligations. As we acquire additional wastewater disposal facilities or expand our existing wastewater disposal facilities, these obligations will increase. Additionally, in the future, regulatory agencies may require us to increase the amount of our closure bonds at existing wastewater disposal facilities. Moreover, actual costs could exceed our current expectations, as a result of, among other things, federal, state or local government regulatory action, increased costs charged by service providers that assist in closing wastewater disposal facilities and additional environmental remediation requirements. Increased regulatory requirements regarding our existing or future wastewater disposal facilities, including the requirement to pay increased closure and post-closure costs or to establish increased financial assurance for such activities could substantially increase our operating costs and cause our available cash that we have to distribute to our unitholders to decline.

Constraints in the supply of equipment used in providing services to our customers and replacement parts for such could affect our ability to execute our growth strategies.

        Equipment used in providing services to our customers is normally readily available. Market conditions could trigger constraints in the supply chain of certain equipment or replacement parts for such equipment, which could have a material adverse effect on our business. The majority of our risk associated with supply chain constraints occurs in those situations where we have a relationship with a single supplier for a particular resource.

If we are unable to fully protect our intellectual property rights, we may suffer a loss in our competitive advantage or market share.

        We do not have patents or patent applications relating to many of our proprietary chemicals. If we are not able to maintain the confidentiality of our trade secrets, or if our competitors are able to replicate our technology or services, our competitive advantage would be diminished. We also cannot assure you that any patents we may obtain in the future would provide us with any significant commercial benefit or would allow us to prevent our competitors from employing comparable technologies or processes.

Technology advancements in well service technologies, including those involving recycling of saltwater or the replacement of water in fracturing fluid, could have a material adverse effect on our business, financial condition and results of operations.

        The oilfield services industry is characterized by rapid and significant technological advancements and introductions of new products and services using new technologies. The saltwater disposal industry is subject to the introduction of new waste treatment and disposal techniques and services using new technologies including those involving recycling of saltwater, some of which may be subject to patent protection. As competitors and others use or develop new technologies or technologies comparable to ours in the future, we may lose market share or be placed at a competitive disadvantage. For example, some oil and gas producers are focusing on developing and utilizing non-water fracturing techniques, including those utilizing propane, carbon dioxide or nitrogen instead of water. Further, we may face competitive pressure to implement or acquire certain new technologies at a substantial cost. Some of our competitors may have greater financial, technical and personnel resources than we do, which may allow them to gain technological advantages or implement new technologies before we can. Additionally, we may be unable to implement new technologies or products at all, on a timely basis or at an acceptable cost. New technology could also make it easier for our customers to vertically

30

Table of Contents

integrate their operations or reduce the amount of waste produced in oil and gas drilling and production activities, thereby reducing or eliminating the need for third-party disposal. Limits on our ability to effectively use or implement new technologies may have a material adverse effect on our business, financial condition and results of operations.

We may be adversely affected by uncertainty in the global financial markets and a worldwide economic downturn.

        Our future results may be impacted by uncertainty caused by a worldwide economic downturn, continued volatility or deterioration in the debt and equity capital markets, inflation, deflation or other adverse economic conditions that may negatively affect us or parties with whom we do business resulting in a reduction in our customers' spending and their non-payment or inability to perform obligations owed to us, such as the failure of customers to honor their commitments or the failure of major suppliers to complete orders. Additionally, credit market conditions may change slowing our collection efforts as customers may experience increased difficulty in obtaining requisite financing, potentially leading to lost revenue and higher than normal accounts receivable. In the event of the financial distress or bankruptcy of a customer, we could lose all or a portion of such outstanding accounts receivable associated with that customer. Further, if a customer was to enter into bankruptcy, it could also result in the cancellation of all or a portion of our service contracts with such customer at significant expense to us.

        The current global economic environment may adversely impact our ability to issue debt. Any economic uncertainty may cause institutional investors to respond to their borrowers by increasing interest rates, enacting tighter lending standards or refusing to refinance existing debt upon its maturity or on terms similar to the expiring debt. However, due to the above listed factors, we cannot be certain that additional funding will be available if needed and, to the extent required, on acceptable terms.

Our operations are subject to inherent risks, some of which are beyond our control. These risks may be self-insured, or may not be fully covered under our insurance policies.

        Our operations are subject to hazards inherent in the oil and gas industry, such as, but not limited to, accidents, blowouts, explosions, craterings, fires, oil spills and releases of drilling, completion or fracturing fluids or wastewater into the environment. These conditions can cause:

•

disruption in operations;



•

substantial repair or remediate costs;



•

personal injury or loss of human life;



•

significant damage to or destruction of property, plant and equipment;



•

environmental pollution, including groundwater contamination;



•

impairment or suspension of operations; and



•

substantial revenue loss.

        The occurrence of a significant event or adverse claim in excess of the insurance coverage that we maintain or that is not covered by insurance could have a material adverse effect on our liquidity, consolidated results of operations and consolidated financial condition. Any interruption in our services due to pipeline breakdowns or necessary maintenance or repairs could reduce sales revenues and earnings. In addition, claims for loss of oil and gas production and damage to formations can occur in the well services industry. Litigation arising from a catastrophic occurrence at a location where our equipment and services are being used may result in our being named as a defendant in lawsuits asserting large claims.

31

Table of Contents

        We do not have insurance against all foreseeable risks, either because insurance is not available or because of the high premium costs. The occurrence of an event not fully insured against or the failure of an insurer to meet its insurance obligations could result in substantial losses. In addition, we may not be able to maintain adequate insurance in the future at rates we consider reasonable. Insurance may not be available to cover any or all of the risks to which we are subject, or, even if available, it may be inadequate, or insurance premiums or other costs could rise significantly in the future so as to make such insurance prohibitively expensive.

The deterioration of the financial condition of our customers could adversely affect our business.

        During times when the gas or crude oil markets weaken, our customers are more likely to experience financial difficulties, including being unable to access debt or equity financing, which could result in a reduction in our customers' spending for our services. In addition, in the course of our business we hold accounts receivable from our customers. In the event of the financial distress or bankruptcy of a customer, we could lose all or a portion of such outstanding accounts receivable associated with that customer. Further, if a customer was to enter into bankruptcy, it could also result in the cancellation of all or a portion of our service contracts with such customer at significant expense or loss of expected revenues to us.

We may be required to take write-downs of the carrying values of our long-lived assets and finite-lived intangible assets.

        We evaluate our long-lived assets, such as property and equipment, and finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that their carrying value may not be recoverable. Recoverability is measured by a comparison of their carrying amount to the estimated undiscounted cash flows to be generated by those assets. Based on specific market factors and circumstances at the time of prospective impairment reviews and the continuing evaluation of development plans, economics and other factors, we may be required to write down the carrying value of our long-lived and finite-lived intangible assets. In the nine months ended September 30, 2017, we did not record an impairment on our long-lived assets or an impairment on our finite-lived intangible assets.

We may be required to take a write-down of the carrying value of goodwill.

        We conduct our annual goodwill impairment assessment during the fourth quarter of each year, or more frequently if an event or circumstance indicates that they carrying value of reporting unit may exceed the fair value. When possible impairment is indicated, we value the implied goodwill to compare it with the carrying amount of goodwill. If the carrying amount of goodwill exceeds its implied fair value, an impairment charge is recorded. The fair value of goodwill is based on estimates and assumptions applied by us such as revenue growth rates, operating margins, weighted-average costs of capital, market multiples, and future market conditions and as affected by numerous factors, including the general economic environment and levels of exploration and production activity of oil and gas companies, our financial performance and trends, and our strategies and business plans, among others. As a result of this annual impairment assessment, we may be required to write down the carrying value of goodwill. In the nine months ended September 30, 2017, we did not record an impairment on goodwill.

Seasonal weather conditions and natural disasters could severely disrupt normal operations and harm our business.

        Our water solutions operations are located primarily in the southern, mid-western and eastern United States. We also have fluids management operations in Western Canada. Certain of these areas are adversely affected by seasonal weather conditions, primarily in the winter and spring. During

32

Table of Contents

periods of heavy snow, ice or rain, we may be unable to move our equipment between locations, thereby reducing our ability to provide services and generate revenues. In particular, in Canada, wet weather and the spring thaw may make the ground unstable. Consequently, municipalities and provincial transportation departments enforce road bans that restrict the movement of rigs and other heavy equipment, thereby reducing activity levels. The timing and length of the road bans depend on weather conditions leading to the spring thaw and during the thawing period. Additionally, certain oil and gas producing areas are located in areas that are inaccessible other than during the winter months, because the ground surrounding the drilling sites in these areas consists of swampy terrain known as muskeg. Rigs and other necessary equipment cannot cross this terrain to reach the drilling site until the muskeg freezes. Additionally, extended drought conditions in our operating regions could impact our ability to source sufficient water for our customers or increase the cost for such water. As a result, a natural disaster or inclement weather conditions could severely disrupt the normal operation of our business and adversely impact our financial condition and results of operations.

We are subject to cyber security risks. A cyber incident could occur and result in information theft, data corruption, operational disruption and/or financial loss.

        The oil and gas industry has become increasingly dependent on digital technologies to conduct certain processing activities. For example, we depend on digital technologies to perform many of our services and to process and record financial and operating data. At the same time, cyber incidents, including deliberate attacks or unintentional events, have increased. The U.S. government has issued public warnings that indicate that energy assets might be specific targets of cyber security threats. Our technologies, systems and networks, and those of our vendors, suppliers and other business partners, may become the target of cyberattacks or information security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss or destruction of proprietary and other information, or other disruption of business operations. In addition, certain cyber incidents, such as surveillance, may remain undetected for an extended period. Our systems and insurance coverage for protecting against cyber security risks may not be sufficient. As cyber incidents continue to evolve, we may be required to expend additional resources to continue to modify or enhance our protective measures or to investigate and remediate any vulnerability to cyber incidents. Our insurance coverage for cyberattacks may not be sufficient to cover all the losses we may experience as a result of such cyberattacks.

A terrorist attack or armed conflict could harm our business.

        The occurrence or threat of terrorist attacks in the United States, Canada or other countries, anti-terrorist efforts and other armed conflicts involving the United States, Canada or other countries, including continued hostilities in the Middle East, may adversely affect the United States, Canada and global economies and could prevent us from meeting our financial and other obligations. If any of these events occur, the resulting political instability and societal disruption could reduce overall demand for oil and gas, potentially putting downward pressure on demand for our services and causing a reduction in our revenues. Oil and gas related facilities could be direct targets of terrorist attacks, and our operations could be adversely impacted if infrastructure integral to our customers' operations is destroyed or damaged. Costs for insurance and other security may increase as a result of these threats, and some insurance coverage may become more difficult to obtain, if available at all.

We engage in transactions with related parties and such transactions present possible conflicts of interest that could have an adverse effect on us.

        We have entered into a significant number of transactions with related parties. The details of certain of these transactions are set forth in the section "Certain Relationships and Related Party Transactions." Related party transactions create the possibility of conflicts of interest with regard to our

33

Table of Contents

management. Such a conflict could cause an individual in our management to seek to advance his or her economic interests above ours. Further, the appearance of conflicts of interest created by related party transactions could impair the confidence of our investors. Our board of directors regularly reviews these transactions. Notwithstanding this, it is possible that a conflict of interest could have a material adverse effect on our liquidity, results of operations and financial condition.

The adoption of more stringent trucking legislation or regulations may increase our costs and could have a material adverse effect on our liquidity, consolidated results of operations, and consolidated financial condition.

        In connection with the services we provide in the United States and Canada, we operate as a motor carrier and therefore are subject to regulation by the U.S. Department of Transportation (the "U.S. DOT") and analogous U.S. state agencies, and by Transport Canada and analogous provincial agencies. These regulatory authorities exercise broad powers, governing activities such as the authorization to engage in motor carrier operations and regulatory safety. There are additional regulations specifically relating to the trucking industry, including testing and specification of equipment and product handling requirements. The trucking industry is subject to possible legislative and regulatory changes that may affect the economics of the industry by requiring changes in operating practices or by changing the demand for common or contract carrier services or the cost of providing truckload services. Some of these possible changes include increasingly stringent environmental regulations and changes in the regulations that govern the amount of time a driver may drive in any specific period, onboard black box recorder devices or limits on vehicle weight and size.

        In the United States, interstate motor carrier operations are subject to safety requirements developed and implemented by the U.S. DOT. Intrastate motor carrier operations often are subject to state safety regulations that mirror federal regulations. Such matters as weight and dimension of equipment are also subject to federal and state laws and regulations. In Canada, as the Canadian government continues to develop and propose regulations relating to fuel quality, engine efficiency and GHG emissions, we may experience an increase in costs related to truck purchases and maintenance, impairment of equipment productivity, a decrease in the residual value of vehicles, unpredictable fluctuations in fuel prices and an increase in operating expenses. Increased truck traffic may contribute to deteriorating road conditions in some areas where our operations are performed. Our operations, including routing and weight restrictions, could be affected by road construction, road repairs, detours and state and local regulations and ordinances restricting access to certain roads. In addition, proposals to increase taxes, including taxes on motor fuels, are also made from time to time, and any such increase would increase our operating costs. Also, local regulation of permitted routes and times on specific roadways could adversely affect our operations. We cannot predict whether, or in what form, any legislative or regulatory changes or municipal ordinances applicable to our logistics operations will be enacted and to what extent any such legislation or regulations could increase our costs or otherwise adversely affect our business or operations.

        From time to time, various legislative proposals are introduced, including proposals to increase federal, state or local taxes, including taxes on motor fuels, which may increase our costs or adversely affect the recruitment of drivers. Management cannot predict whether, or in what form, any increase in such taxes applicable to us will be enacted. We may be required to increase operating expenses or capital expenditures in order to comply with any new laws, regulations or other restrictions.

Disruptions in the transportation services of trucking companies transporting wastewater and other oilfield products could have a material adverse effect on our results.

        We use trucks to transport some produced water to our wastewater disposal facilities, as well as to transport sand in the Rockies and Bakken areas. In recent years, certain states, such as North Dakota and Texas, and state counties have increased enforcement of weight limits on trucks used to transport

34

Table of Contents

raw materials on their public roads. It is possible that the states, counties and cities in which we operate our business may modify their laws to further reduce truck weight limits or impose curfews or other restrictions on the use of roadways. Such legislation and enforcement efforts could result in delays in, and increased costs to, transport produced water to our wastewater disposal facilities or to transport sand, which may either increase our operating costs or reduce the amount of produced water transported to our facilities or sand hauled for our customers. Such developments could decrease our operating margins or amounts of produced water or sand and thereby have a material adverse effect on our results of operations and financial condition.

A significant increase in fuel prices may adversely affect our transportation costs, which could have a material adverse effect on our results of operations and financial condition.

        Fuel is one of our significant operating expenses, and a significant increase in fuel prices could result in increased transportation costs. The price and supply of fuel is unpredictable and fluctuates based on events such as geopolitical developments, supply and demand for oil and gas, actions by oil and gas producers, war and unrest in oil producing countries and regions, regional production patterns and weather concerns. A significant increase in fuel prices could increase the price of, and therefore reduce demand for, our services, which could affect our results of operations and financial condition.

Our Canadian operations subject us to currency translation risk, which could cause our results of operations and financial condition to fluctuate significantly from period to period.

        A portion of our revenue is derived from our Canadian activities and operations. As a result, we translate the results of our operations and financial condition of our Canadian operations into U.S. dollars. Therefore, our reported results of operations and financial condition are subject to changes in the exchange rate between the two currencies. Fluctuations in foreign currency exchange rates could affect our revenue, expenses and operating margins. As we continue to expand our international operations, we become more exposed to the effects of fluctuations in currency exchange rates. Currently, we do not hedge our exposure to changes in foreign exchange rates.

Risks Related to our Class A Common Stock

We do not expect to pay any dividends to the holders of the Class A common stock in the foreseeable future and the availability and timing of future dividends, if any, is uncertain.

        We currently intend to retain future earnings, if any, to finance the expansion of our business, including the repayment of our debt, and do not expect to declare or pay any dividends on our Class A common stock in the foreseeable future. Our Credit Agreement places certain restrictions on the ability of us and our subsidiaries to pay dividends. Consequently, your only opportunity to achieve a return on your investment in us will be if you sell your Class A common stock at a price greater than you paid for it. There is no guarantee that the price of our Class A common stock that will prevail in the market will ever exceed the price that you pay. We may amend our Credit Agreement or enter into new debt arrangements that also prohibit or restrict our ability to pay dividends on our Class A common stock.

        Subject to such restrictions, our board of directors will determine the amount and timing of stockholder dividends, if any, that we may pay in future periods. In making this determination, our directors will consider all relevant factors, including the amount of cash available for dividends, capital expenditures, covenants, prohibitions or limitations with respect to dividends, applicable law, general operational requirements and other variables. We cannot predict the amount or timing of any future dividends you may receive, and if we do commence the payment of dividends, we may be unable to pay, maintain or increase dividends over time. Therefore, you may not be able to realize any return on your investment in our Class A common stock for an extended period of time, if at all. Please read "Dividend Policy."

If we fail to develop or maintain an effective system of internal controls, we may not be able to accurately report our financial results or prevent fraud. As a result, current and potential stockholders could lose confidence in our financial reporting, which would harm our business and the trading price of our Class A common stock.

        Effective internal controls are necessary for us to provide reliable financial reports, prevent fraud and operate successfully as a public company. We are not currently required to comply with the SEC's rules implementing Section 404 of Sarbanes-Oxley and therefore are not required to make a formal assessment of the effectiveness of our internal controls over financial reporting for that purpose. If we cannot provide reliable financial reports or prevent fraud, our reputation and operating results would be harmed. We cannot be certain that our efforts to develop and maintain our internal controls will be successful, that we will be able to maintain adequate controls over our financial processes and reporting in the future or that we will be able to comply with our obligations under Sections 302 and 404 of Sarbanes-Oxley. Any failure to develop or maintain effective internal controls, or difficulties encountered in implementing or improving our internal controls, could harm our operating results or cause us to fail to meet our reporting obligations. Ineffective internal controls could also cause investors to lose confidence in our reported financial information, which would likely have a negative effect on the trading price of our Class A common stock.

Since we are an "emerging growth company," we are not required to comply with certain disclosure requirements that are applicable to other public companies and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our Class A common stock less attractive to investors.

        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 public companies, including, but not limited to, longer phase-in periods for the adoption of new or revised financial accounting standards, not being required to comply with the auditor attestation requirements of Section 404 of Sarbanes-Oxley, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We intend to take advantage of all of the reduced reporting requirements and exemptions, including the longer phase-in periods for the adoption of new or revised financial accounting standards under Section 107 of the JOBS Act, until we are no longer an emerging growth company. Our election to use the phase-in periods permitted by this election may make it difficult to compare our financial statements to those of non-emerging growth companies and other emerging growth companies that have opted out of the longer phase-in periods under Section 107 of the JOBS Act and who will comply with new or revised financial accounting standards. If we were to subsequently elect instead to comply with these public company effective dates, such election would be irrevocable pursuant to Section 107 of the JOBS Act.

        We cannot predict if investors will find our Class A common stock less attractive because we will rely on these exemptions. If some investors find our Class A common stock less attractive as a result, there may be a less active trading market for our Class A common stock and our Class A common stock price may be more volatile. Under the JOBS Act, "emerging growth companies" can delay adopting new or revised accounting standards until such time as those standards apply to private companies.

Future sales of our equity securities, or the perception that such sales may occur, may depress our share price, and any additional capital raised through the sale of equity or convertible securities may dilute your ownership in us.

        Subject to certain limitations and exceptions, Legacy Owner Holdco and its permitted transferees may exchange their SES Holdings LLC Units (together with a corresponding number of shares of Class B common stock) for shares of Class A common stock (on a one-for-one basis, subject to conversion rate adjustments for stock splits, stock dividends and reclassification and other similar transactions) and then sell those shares of Class A common stock. Additionally, we may in the future issue our previously authorized and unissued securities. We are authorized to issue 350 million shares of Class A common stock, 40 million shares of Class A-2 common stock, 150 million shares of Class B common stock and 50 million shares of preferred stock with such designations, preferences and rights as determined by our board of directors. The potential issuance of such additional shares of equity securities will result in the dilution of the ownership interests of the holders of our Class A common stock and may create downward pressure on the trading price, if any, of our Class A common stock. The registration rights of our Legacy Owners and the sales of substantial amounts of our Class A common stock following the effectiveness of shelf registration statements for the benefit of such holders, or the perception that these sales may occur, could cause the market price of our Class A common stock to decline and impair our ability to raise capital. We also may grant additional registration rights in connection with any future issuance of our capital stock.

        We cannot predict the size of future issuances of our Class A common stock or securities convertible into Class A common stock or the effect, if any, that future issuances and sales of shares of our Class A common stock will have on the market price of our Class A common stock. Sales of substantial amounts of our Class A common stock (including shares issued in connection with an acquisition), or the perception that such sales could occur, may adversely affect prevailing market prices of our Class A common stock.

If securities or industry analysts do not publish research or reports about our business, if they adversely change their recommendations regarding our Class A common stock or if our operating results do not meet their expectations, the share price for our Class A common stock could decline.

        The trading market for our Class A common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause the price or trading volume of our Class A common stock to decline. Moreover, if one or more of the analysts who cover us downgrades our Class A common stock or if our operating results do not meet their expectations, the share price of our Class A common stock could decline.

Provisions in our amended and restated certificate of incorporation and amended and restated bylaws and Delaware law may discourage a takeover attempt even if a takeover might be beneficial to our stockholders.

        Provisions contained in our amended and restated certificate of incorporation and amended and restated bylaws could make it more difficult for a third party to acquire us. Provisions of our amended and restated certificate of incorporation and amended and restated bylaws impose various procedural and other requirements, which could make it more difficult for stockholders to effect certain corporate actions. For example, our amended and restated certificate of incorporation authorizes our board of directors to determine the rights, preferences, privileges and restrictions of unissued series of preferred stock without any vote or action by our stockholders. Thus, our board of directors can authorize and issue shares of preferred stock with voting or conversion rights that could adversely affect the voting or other rights of holders of our capital stock. These rights may have the effect of delaying or deterring a change of control of our company. Additionally, our amended and restated bylaws establish limitations

37

Table of Contents

on the removal of directors and on the ability of our stockholders to call special meetings and include advance notice requirements for nominations for election to our board of directors and for proposing matters that can be acted upon at stockholder meetings. See "Description of Capital Stock—Anti-Takeover Effects of Provisions of Our Amended and Restated Certificate of Incorporation, Our Amended and Restated Bylaws and Delaware Law." These provisions could limit the price that certain investors might be willing to pay in the future for shares of our Class A common stock.

        In addition, certain change of control events have the effect of accelerating the payment due under our Tax Receivable Agreements, which could be substantial and accordingly serve as a disincentive to a potential acquirer of our company. See "Risks Related to Our Organizational Structure—In certain cases, payments under the Tax Receivable Agreements may be accelerated and/or significantly exceed the actual benefits, if any, we realize in respect of the tax attributes subject to the Tax Receivable Agreements."

Legacy Owner Holdco controls a significant percentage of our voting power.

        Legacy Owner Holdco beneficially owns 89.2% of our Class B common stock and the Class B common stock represents approximately 33.9% of our outstanding voting capital stock. See "Summary—Organization—144A Offering Reorganization." In addition, certain of our directors are currently employed by Crestview Advisors, L.L.C. ("Crestview Partners"), our private equity sponsor and, through Crestview GP, the manager of funds that hold the largest equity interest in Legacy Owner Holdco. Other funds controlled by Crestview GP also have an interest in our currently outstanding shares of our Class A common stock, representing an additional 3.6% of our outstanding voting capital. Collectively, these holders control approximately 37.4% of our voting shares. Holders of Class A common stock, Class A-2 common stock and Class B common stock generally will vote together as a single class on all matters presented to our stockholders for their vote or approval. Consequently, Legacy Owner Holdco will be able to strongly influence all matters that require approval by our stockholders, including the election and removal of directors, changes to our organizational documents and approval of acquisition offers and other significant corporate transactions, regardless of whether other stockholders believe that a transaction is in their own best interests. This concentration of ownership will limit your ability to influence corporate matters, and as a result, actions may be taken that you may not view as beneficial.

Our amended and restated certificate of incorporation contains a provision renouncing our interest and expectancy in certain corporate opportunities, which could adversely affect our business or prospects.

        Our amended and restated certificate of incorporation provides that, to the fullest extent permitted by applicable law, we renounce any interest or expectancy in any business opportunity that involves any aspect of the energy business or industry and that may be from time to time presented to any member of (i) Legacy Owner Holdco; Crestview Partners II SES Investment, LLC ("Crestview Holdings A"); any funds, limited partnerships or other investment entities or vehicles managed by Crestview Partners or controlled by Crestview GP; B-29 Investments, LP; Sunray Capital, LP; Proactive Investments, LP and their respective affiliates, other than us (collectively, the "SES Group"); (ii) SCF-VI, L.P., SCF-VII, L.P. and SCF-VII(A), L.P. and their respective affiliates, other than us (collectively, the "SCF Group"); (iii) the other entities (existing and future) that participate in the energy industry and in which the SES Group and SCF Group own substantial equity interests (the "Portfolio Companies") or (iv) any director or officer of the corporation who is also an employee, partner, member, manager, officer or director of any member of the SES Group, the SCF Group or the Portfolio Companies, including our Executive Chairman, John D. Schmitz, our director, David C. Baldwin, and our Executive Vice President, Business Strategy, Cody Ortowski, even if the opportunity is one that we might reasonably have pursued or had the ability or desire to pursue if granted the opportunity to do so. Mr. Schmitz controls both B-29 Investments, LP and Sunray Capital, LP and is a direct and indirect

38

Table of Contents

beneficiary of these provisions in our amended and restated certificate of incorporation. Our amended and restated certificate of incorporation further provides that no such person or party shall be liable to us by reason of the fact that such person pursues any such business opportunity, or fails to offer any such business opportunity to us.

        As a result, any member of the SES Group, SCF Group or the Portfolio Companies or any director or officer of the corporation who is also an employee, partner, member, manager, officer or director of any member of the SES Group, SCF Group or the Portfolio Companies may become aware, from time to time, of certain business opportunities, such as acquisition opportunities, and may direct such opportunities to other businesses in which they have invested, in which case we may not become aware of or otherwise have the ability to pursue such opportunity. Further, such businesses may choose to compete with us for these opportunities. As a result, by renouncing our interest and expectancy in any business opportunity that may be from time to time presented to any member of the SES Group, SCF Group or the Portfolio Companies or any director or officer of the corporation who is also an employee, partner, member, manager, officer or director of any member of the SES Group, SCF Group or the Portfolio Companies, our business or prospects could be adversely affected if attractive business opportunities are procured by such parties for their own benefit rather than for ours. See "Certain Relationships and Related Party Transactions."

A significant reduction by Crestview GP or the SCF Group of either of their respective ownership interests in us could adversely affect us.

        We believe that Crestview GP's and the SCF Group's beneficial ownership interests in us provides each with an economic incentive to assist us to be successful. Neither Crestview GP nor the SCF Group is subject to any obligation to maintain its ownership interest in us and either may elect at any time to sell all or a substantial portion of or otherwise reduce its ownership interest in us. If either Crestview GP or the SCF Group sells all or a substantial portion of its ownership interest in us, it may have less incentive to assist in our success and its affiliate(s) that are expected to serve as members of our board of directors may resign. Such actions could adversely affect our ability to successfully implement our business strategies which could adversely affect our cash flows or results of operations.

We may issue preferred stock whose terms could adversely affect the voting power or value of our Class A common stock.

        Our amended and restated certificate of incorporation authorizes us to issue, without the approval of our stockholders, one or more classes or series of preferred stock having such designations, preferences, limitations and relative rights, including preferences over our Class A common stock respecting dividends and distributions, as our board of directors may determine. The terms of one or more classes or series of preferred stock could adversely impact the voting power or value of our Class A common stock. For example, we might grant holders of preferred stock the right to elect some number of our directors in all events or on the happening of specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we might assign to holders of preferred stock could affect the residual value of the Class A common stock.

Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.

        Our amended and restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty

To the fullest extent permitted by law, any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of, and consented to, the provisions of our amended and restated certificate of incorporation described in the preceding sentence. This choice of forum provision may limit a stockholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and such persons. Alternatively, if a court were to find these provisions of our amended and restated certificate of incorporation inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition or results of operations.

Risks Related to Our Organizational Structure

We are a holding company. Our sole material asset is our equity interest in SES Holdings, and accordingly, we are dependent upon distributions and payments from SES Holdings to pay taxes, make payments under the Tax Receivable Agreements and cover our corporate and other overhead expenses.

        We are a holding company and have no material assets other than our equity interest in SES Holdings. Please see "Summary—Organization." We have no independent means of generating revenue. To the extent SES Holdings has available cash, we intend to cause SES Holdings to make (i) generally pro rata distributions to its unitholders, including us, in an amount at least sufficient to allow us to pay our taxes and to make payments under the Tax Receivable Agreements we entered into with the TRA Holders and any subsequent tax receivable agreements that we may enter into in connection with future acquisitions and (ii) non-pro rata payments to us to reimburse us for our corporate and other overhead expenses. We will be limited, however, in our ability to cause SES Holdings and its subsidiaries to make these and other distributions or payments to us due to certain limitations, including the restrictions under our Credit Agreement and the cash requirements and financial condition of SES Holdings. To the extent that we need funds and SES Holdings or its subsidiaries are restricted from making such distributions or payments under applicable law or regulations or under the terms of their financing arrangements or are otherwise unable to provide such funds, our liquidity and financial condition could be adversely affected.

We will be required to make payments under the Tax Receivable Agreements for certain tax benefits we may claim, and the amounts of such payments could be significant.

        In connection with the Select 144A Offering, we entered into two Tax Receivable Agreements which generally provide for the payment by us to the TRA Holders of 85% of the net cash savings, if any, in U.S. federal, state and local income and franchise tax that we actually realize (computed using simplifying assumptions to address the impact of state and local taxes) or are deemed to realize in certain circumstances as a result of certain tax basis increases, net operating losses available to us as a result of certain reorganization transactions entered into in connection with the Select 144A Offering, and certain tax benefits attributable to imputed interest. We will retain the benefit of the remaining 15% of these cash savings.

Table of Contents

        The term of each Tax Receivable Agreement commenced upon the completion of the Select 144A Offering and will continue until all tax benefits that are subject to such Tax Receivable Agreement have been utilized or expired, unless we exercise our right to terminate the Tax Receivable Agreements (or the Tax Receivable Agreements are terminated due to other circumstances, including our breach of a material obligation thereunder or certain mergers or other changes of control) and we make the termination payment specified in the Tax Receivable Agreements. In addition, payments we make under the Tax Receivable Agreements will be increased by any interest accrued from the due date (without extensions) of the corresponding tax return. In the event that the Tax Receivable Agreements are not terminated and we have sufficient taxable income to utilize all of the tax benefits subject to the Tax Receivable Agreements, the payments due under the Tax Receivable Agreement entered into with Legacy Owner Holdco and Crestview GP are expected to commence in late 2018 and to continue for 20 years after the date of the last exchange of SES Holdings LLC Units, and the payments due under the Tax Receivable Agreement entered into with an affiliate of the Contributing Legacy Owners are expected to commence in late 2019 and to continue for 25 taxable years following the Select 144A Offering.

        The payment obligations under the Tax Receivable Agreements are our obligations and not obligations of SES Holdings, and we expect that the payments we will be required to make under the Tax Receivable Agreements will be substantial. Estimating the amount and timing of payments that may become due under the Tax Receivable Agreements is by its nature imprecise. For purposes of the Tax Receivable Agreements, cash savings in tax generally will be calculated by comparing our actual tax liability (using the actual applicable U.S. federal income tax rate and an assumed combined state and local income and franchise tax rate) to the amount we would have been required to pay had we not been able to utilize any of the tax benefits subject to the Tax Receivable Agreements. The amounts payable, as well as the timing of any payments, under the Tax Receivable Agreements are dependent upon future events and significant assumptions, including the timing of the exchanges of SES Holdings LLC Units, the market price of our Class A common stock at the time of each exchange (since such market price will determine the amount of tax basis increases resulting from the exchange), the extent to which such exchanges are taxable transactions, the amount of the exchanging unitholder's tax basis in its SES Holdings LLC Units at the time of the relevant exchange, the depreciation and amortization periods that apply to the increase in tax basis, the amount of net operating losses available to us as a result of reorganization transactions entered into in connection with the Select 144A Offering, the amount and timing of taxable income we generate in the future, the U.S. federal income tax rate then applicable, and the portion of our payments under the Tax Receivable Agreements that constitute imputed interest or give rise to depreciable or amortizable tax basis.

        Certain of the TRA Holders' rights under the Tax Receivable Agreements are transferable in connection with a permitted transfer of SES Holdings LLC Units or if the TRA Holder no longer holds SES Holdings LLC Units. The payments under the Tax Receivable Agreements will not be conditioned upon the continued ownership interest in either SES Holdings or us of any holder of rights under the Tax Receivable Agreements. Please read "Certain Relationships and Related Party Transactions—Tax Receivable Agreements."

In certain cases, payments under the Tax Receivable Agreements may be accelerated and/or significantly exceed the actual benefits, if any, we realize in respect of the tax attributes subject to the Tax Receivable Agreements.

        If we elect to terminate the Tax Receivable Agreements early or they are terminated early due to our failure to honor a material obligation thereunder or due to certain mergers, asset sales, other forms of business combinations or other changes of control, our obligations under the Tax Receivable Agreements would accelerate and we would be required to make an immediate payment equal to the present value of the anticipated future payments to be made by us under the Tax Receivable

41

Table of Contents

Agreements (determined by applying a discount rate of the lesser of 6.50% per annum, compounded annually, or one-year London Interbank Offered Rate ("LIBOR") plus 100 basis points); and such payment is expected to be substantial. The calculation of anticipated future payments will be based upon certain assumptions and deemed events set forth in the Tax Receivable Agreements, including (i) the assumption that we have sufficient taxable income to fully utilize the tax benefits covered by the Tax Receivable Agreements, (ii) the assumption that any SES Holdings LLC Units (other than those held by us) outstanding on the termination date are exchanged on the termination date and (iii) certain loss or credit carryovers will be utilized in the taxable year that includes the termination date. Any early termination payment may be made significantly in advance of the actual realization, if any, of the future tax benefits to which the termination payment relates.

        As a result of either an early termination or a "change of control" (as defined in the Tax Receivable Agreements, as amended), we could be required to make payments under the Tax Receivable Agreements that exceed our actual cash tax savings under the Tax Receivable Agreements. In these situations, our obligations under the Tax Receivable Agreements could have a substantial negative impact on our liquidity and could have the effect of delaying, deferring or preventing certain mergers, asset sales or other forms of business combinations or changes of control. For example, if the Tax Receivable Agreements were terminated immediately after the Rockwater Merger, the estimated termination payments would have been approximately $174.1 million (calculated using a discount rate equal to the lesser of 6.50% per annum, compounded annually, or one-year LIBOR plus 100 basis points, applied against an undiscounted liability of $234.9 million) in the aggregate. The foregoing number is merely an estimate and the actual payment could differ materially. There can be no assurance that we will be able to finance our obligations under the Tax Receivable Agreements.

        Payments under the Tax Receivable Agreements will be based on the tax reporting positions that we will determine. The TRA Holders will not reimburse us for any payments previously made under the Tax Receivable Agreements if any tax benefits that have given rise to payments under the Tax Receivable Agreements are subsequently disallowed, except that excess payments made to the TRA Holders will be netted against payments that would otherwise be made to the TRA Holders, if any, after our determination of such excess. As a result, in such circumstances, we could make payments that are greater than our actual cash tax savings, if any, and may not be able to recoup those payments, which could adversely affect our liquidity.

        Please read "Certain Relationships and Related Party Transactions—Tax Receivable Agreements."

If SES Holdings were to become a publicly traded partnership taxable as a corporation for U.S. federal income tax purposes, we and SES Holdings might be subject to potentially significant tax inefficiencies, and we would not be able to recover payments previously made by us under the Tax Receivable Agreements even if the corresponding tax benefits were subsequently determined to have been unavailable due to such status.

        We intend to operate such that SES Holdings does not become a publicly traded partnership taxable as a corporation for U.S. federal income tax purposes. A "publicly traded partnership" is a partnership, the interests of which are traded on an established securities market or are readily tradable on a secondary market or the substantial equivalent thereof. Under certain circumstances, exchanges of SES Holdings LLC Units pursuant to an Exchange Right (or our Call Right) or other transfers of SES Holdings LLC Units could cause SES Holdings to be treated as a publicly traded partnership. Applicable U.S. Treasury regulations provide for certain safe harbors from treatment as a publicly traded partnership, and we intend to operate such that exchanges or other transfers of SES Holdings LLC Units qualify for one or more such safe harbors. For example, we intend to limit the number of unitholders of SES Holdings and Legacy Owner Holdco, and the SES Holdings LLC Agreement, provides for limitations on the ability of unitholders of SES Holdings to transfer their SES Holdings LLC Units and will provide us, as managing member of SES Holdings, with the right to impose restrictions (in addition to those already in place) on the ability of unitholders of SES Holdings

42

Table of Contents

to exchange their SES Holdings LLC Units pursuant to an Exchange Right to the extent we believe it is necessary to ensure that SES Holdings will continue to be treated as a partnership for U.S. federal income tax purposes.

        If SES Holdings were to become a publicly traded partnership, significant tax inefficiencies might result for us and for SES Holdings. In addition, we may not be able to realize tax benefits covered under the Tax Receivable Agreements, and we would not be able to recover any payments previously made by us under the Tax Receivable Agreements, even if the corresponding tax benefits (including any claimed increase in the tax basis of SES Holdings' assets) were subsequently determined to have been unavailable.

Legacy Owner Holdco and the Legacy Owners may have interests that conflict with holders of shares of our Class A common stock.

        Legacy Owner Holdco owns approximately 33.9% of the outstanding SES Holdings LLC Units. Because it holds a portion of its ownership interest in our business in the form of direct ownership interests in SES Holdings rather than through us, Legacy Owner Holdco may have conflicting interests with holders of shares of Class A common stock. For example, Legacy Owner Holdco may have different tax positions from us, and decisions we make in the course of running our business, such as with respect to mergers, asset sales, other forms of business combinations or other changes in control, may affect the timing and amount of payments that are received by the TRA Holders under the Tax Receivable Agreements. See "Certain Relationships and Related Party Transactions—Tax Receivable Agreements."

Our ability to use Rockwater's net operating loss carryforwards may be limited.

        As of September 30, 2017, Rockwater had approximately $113.7 million of U.S. federal net operating loss carryforwards ("NOLs"), which will begin to expire in 2029, approximately $79.2 million of state NOLs which will begin to expire in 2018, and approximately $3.4 million of foreign NOLs, which will begin to expire in 2035. Utilization of these NOLs depends on many factors, including our future income, which cannot be assured. In addition, Section 382 of the Internal Revenue Code of 1986, as amended (the "Code"), generally imposes an annual limitation on the amount of NOLs that may be used to offset taxable income when a corporation has undergone an "ownership change" (as determined under Section 382 of the Code). An ownership change generally occurs if one or more stockholders (or groups of stockholders) who are each deemed to own at least 5% of the relevant corporation's stock change their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. In the event that an ownership change has occurred, or were to occur, utilization of the NOLs would be subject to an annual limitation under Section 382 of the Code, determined by multiplying the value of the relevant corporation's stock at the time of the ownership change by the applicable long-term tax-exempt rate as defined in Section 382 of the Code, and potentially increased for certain gains recognized within five years after the ownership change if we have a net built-in gain in our assets at the time of the ownership change. Any unused annual limitation may be carried over to later years until they expire. Rockwater experienced an ownership change in connection with the Rockwater Merger. As a result, some or all of our U.S. federal, state or foreign NOLs could expire before they can be used. In addition, future ownership changes or changes to the U.S. tax laws could limit our ability to utilize our NOLs. To the extent we are not able to offset our future income with our NOLs, this would adversely affect our operating results and cash flows if we attain profitability.

Recently enacted changes to the U.S. federal tax laws could have a negative impact on our business operations, financial condition and earnings.

        Recently enacted legislation commonly referred to as the "Tax Cuts and Jobs Act" (the "TCJA") includes significant changes to the taxation of business entities. Although the TCJA includes a provision for lower corporate income tax rates, those rate reductions could be offset by other changes intended to broaden the tax base, for example, by limiting the ability to deduct interest expense and net operating losses. We continue to examine the impact the TCJA may have on our business and financial results. This prospectus does not discuss the TCJA or the manner in which it might affect purchasers of our common stock. Prospective investors are urged to consult their tax advisors regarding the effect of the TCJA on an investment in the shares of our common stock.

Overview

        We are a leading provider of total water management and chemical solutions to the unconventional oil and gas industry in the United States and Western Canada. Within the major shale plays in the United States, we believe we are a market leader in sourcing, transfer (both by permanent pipeline and temporary hose) and temporary containment of water prior to its use in drilling and completion activities associated with hydraulic fracturing or "fracking," which we collectively refer to as "pre-frac water services," as well as well testing and flowback services immediately following the well completion. In most of our areas of operations, we also provide additional complementary water-related services that support oil and gas well completion and production activities including monitoring, treatment, hauling and water recycling and disposal. We also develop and manufacture a full suite of specialty chemicals used in well completions and production chemicals used to enhance performance over the life of a well. Our services are necessary to establish and maintain production of oil and gas over the productive life of a well. Water and related services are increasingly important as oil and gas E&P companies have increased the complexity and completion intensity of horizontal wells (including the use of longer horizontal wellbore laterals, tighter spacing of frac stages in the laterals and increased water, proppant and chemical use per foot of lateral) in order to improve production and recovery of hydrocarbons. We have historically generated a substantial majority of our revenues through providing total water solutions to our customers, and we believe we are the only company that provides total water solutions together with complementary chemical products and related expertise, which we believe gives us a unique competitive advantage in our industry.

Our Segments

        Prior to the Rockwater Merger, we reviewed our operations through the following three business segments: (i) Water Solutions, (ii) Accommodations and Rentals and (iii) Wellsite Completion and Construction Services. Following the completion of the Rockwater Merger, we offer our services through the following three operating segments: (i) Water Solutions, (ii) Oilfield Chemicals and (iii) Wellsite Services.

•

Water Solutions.  Our Water Solutions segment is operated primarily under our subsidiary, Select LLC, and provides water-related services to customers that include major integrated oil companies and independent oil and natural gas producers. These services include: the sourcing of water; the transfer of the water to the wellsite through permanent pipeline infrastructure and temporary hose; the containment of fluids off- and on-location; measuring and monitoring of water; the filtering and treatment of fluids, well testing and handling of flowback and produced formation water; and the transportation and recycling or disposal of drilling, completion and production fluids.



•

Oilfield Chemicals.  Our Oilfield Chemicals segment is operated primarily under our subsidiary, Rockwater LLC, and develops, manufactures and provides a full suite of chemicals utilized in hydraulic fracturing, stimulation, cementing and well completions, including polymers that create

53

Table of Contents

viscosity, crosslinkers, friction reducers, surfactants, buffers, breakers and other chemical technologies, to leading pressure pumping service companies in the United States. We also provide production chemicals solutions, which are applied to underperforming wells in order to enhance well performance and reduce production costs through the use of production treating chemicals, corrosion and scale monitoring, chemical inventory management, well failure analysis and lab services.

•

Wellsite Services.  Our Wellsite Services segment provides a number of services across the U.S. and Canada and is operated primarily under our subsidiaries Peak, Affirm and Rockwater LLC. Peak provides workforce accommodations and surface rental equipment supporting drilling, completion and production operations to the U.S. onshore oil and gas industry. Affirm provides oil and gas operators with a variety of services, including crane and logistics services, wellsite and pipeline construction and field services. Operating under Rockwater LLC, we also offer sand hauling and logistics services in the Rockies and Bakken regions as well as water transfer, containment, fluids hauling and other rental services in Western Canada.

How We Generate Revenue

        We currently generate a significant majority of our revenue through our Water Solutions segment, specifically through total water management associated with hydraulic fracturing. We generate our revenue through customer agreements with fixed pricing terms but no guaranteed throughput amounts. While we have some long-term pricing arrangements, most of our water and water-related services are priced based on prevailing market conditions, giving due consideration to the specific requirements of the customer.

        We also generate revenue through our Oilfield Chemicals segment, which provides completion, specialty chemicals and production chemicals, and our Wellsite Services segment, which provides workforce accommodations and related rentals; a variety of wellsite completion and construction services, including wellsite construction, pipeline construction, field services and well services; sand hauling and fluids logistics services; and water transfer, fluids hauling, containment and rentals services in Canada. We invoice the majority of our Oilfield Chemicals customers for services provided under such segment based on the quantity of chemicals used or pursuant to short-term contracts as the customer's needs arise. We invoice the majority of our customers for services under our Wellsite Services segments on a per job basis or pursuant to short-term contracts as the customer's needs arise.

Costs of Conducting Our Business

        The principal expenses involved in conducting our business are labor costs, equipment costs (including depreciation, repair and maintenance and leasing costs), raw materials and water sourcing costs and fuel costs. Our fixed costs are relatively low and a large portion of the costs we incur in our business are only incurred when we provide water, water-related services, chemicals and chemical-related services to our customers.

        Labor costs associated with our employees represent the most significant costs of our business. The majority of our recurring labor costs are variable and are incurred only while we are providing water and water-related services. We also incur costs to employ personnel to sell and supervise our services and perform maintenance on our assets which are not directly tied to our level of business activity. We also incur selling, general and administrative costs for compensation of our administrative personnel at our field sites and in our corporate headquarters.

        We incur significant equipment costs in connection with the operation of our business, including depreciation, repair and maintenance and leasing costs. Our depreciation costs are expected to decline over the next few years as a result of recent impairments as well as the decline in our capital

54

Table of Contents

expenditures over the last three years, which will be partially offset by any future capital expenditures on depreciable assets.

        We incur raw material costs in manufacturing our chemical products, as well as water sourcing costs in connection with obtaining strategic and reliable water sources to provide repeatable water volumes to our customers.

        Fuel costs associated with water transportation are a significant operating cost. Fuel prices impact our transportation costs, which affect the pricing and demand of our services, and have an impact on our results of operations.

Public Company Costs

        General and administrative expenses related to being a publicly traded company include: Exchange Act reporting expenses; expenses associated with compliance with Sarbanes-Oxley; expenses associated with maintaining our listing on the NYSE; incremental independent auditor fees; incremental legal fees; investor relations expenses; registrar and transfer agent fees; incremental director and officer liability insurance costs; and director compensation. We expect that general and administrative expenses related to being a publicly traded company will increase in future periods. Costs incurred by us for corporate and other overhead expenses will be reimbursed by SES Holdings pursuant to the SES Holdings LLC Agreement.

How We Evaluate Our Operations

        We use a variety of operational and financial metrics to assess our performance. Among other measures, management considers each of the following:

•

Revenue;



•

Gross Profit;



•

EBITDA; and



•

Adjusted EBITDA.

Revenue

        We analyze our revenue and assess our performance by comparing actual monthly revenue to our internal projections. We also assess incremental changes in revenue compared to incremental changes in direct operating costs, and selling, general and administrative expenses across our operating segments to identify potential areas for improvement, as well as to determine whether segments are meeting management's expectations.

Gross Profit

        To measure our financial performance, we analyze our gross profit, which we define as revenues less direct operating expenses (including depreciation expense). We believe gross profit is a meaningful metric because it provides insight on profitability and true operating performance based on the historical cost basis of our assets. We also compare gross profit to prior periods and across locations to identify underperforming locations.

EBITDA and Adjusted EBITDA

        We view EBITDA and Adjusted EBITDA as important indicators of performance. We define EBITDA as net income, plus taxes, interest expense, and depreciation and amortization. We define Adjusted EBITDA as EBITDA plus/(minus) loss/(income) from discontinued operations, plus any

55

Factors Affecting the Comparability of Our Results of Operations to Our Historical Results of Operations

        Our future results of operations may not be comparable to our historical results of operations for the periods presented, primarily for the reasons described below.

Rockwater Merger

        On November 1, 2017, we completed the Rockwater Merger whereby we acquired the business, assets and operations of Rockwater. For more information, see "Summary—Recent Developments" and "Summary—Organization—Rockwater Merger Reorganization."

        Our historical financial statements included in this prospectus for periods prior to November 1, 2017 do not include the results of operations of Rockwater. The standalone historical financial statements of Rockwater are included elsewhere in this prospectus. The pro forma financial information presented in this prospectus presents our results of operations as if the Rockwater Merger had occurred on January 1, 2016. As a result, the historical financial data and pro forma financial information presented in this prospectus may not give an accurate indication of what our results of operations would have been if the Rockwater Merger had been completed at the beginning of the periods presented.

Acquisition Activity

        As further described under "Summary—Recent Developments," we are continuously evaluating potential investments, particularly in water transfer, infrastructure and other water-related services. To the extent we consummate acquisitions, any incremental revenues or expenses from such transactions would not be included in our historical results of operations. For example, on March 10, 2017, we completed the GRR Acquisition, and the results of operations of the GRR Entities are reflected in our results of operations from the acquisition date forward.

Impact of Industry Conditions on Our Operating Results

        Demand for oilfield services depends substantially on drilling, completion and production activity by E&P companies, which, in turn, depends largely upon the current and anticipated profitability of developing oil and natural gas reserves. Beginning in the second half of 2014, oil prices began a rapid and significant decline that continued through the first half of 2016. This decline led to a significant contraction on demand for oilfield services and significantly and negatively impacted our operating results. Beginning in the third quarter of 2016, oil prices began to recover, as did demand for our services. In the discussion of our operating results below, we reference the fluctuations in industry conditions in connection with certain changes in our results of operations.
