RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together with the risks and uncertainties described elsewhere in this prospectus, including our historical combined financial statements and the related notes contained elsewhere in this prospectus, before you decide to purchase shares of our common stock. If any of the following risks or uncertainties actually occurs, our business, financial condition, results of operations, cash flow and prospects could be materially and adversely affected. As a result, the price of our common stock could decline and you could lose all or part of your investment in our common stock.

Risks Related to Our Business

A decline in the production of CCRs by our coal-fired utility industry customers due to environmental regulations or otherwise could negatively impact our profitability and hinder our growth.

Many of our services are dependent upon the production of CCRs by our coal-fired utility customers. The coal-fired utility industry is facing a number of new and pending initiatives by regulatory authorities seeking to address air and water pollution, greenhouse gas emissions and management and disposal of CCRs. In recent years, federal and state environmental regulation has imposed more stringent requirements regarding emission of air pollutants and other toxic chemicals, reduction of greenhouse gas emissions and water quality impacts from coal operations. Adoption of more stringent regulations governing coal combustion, water discharges or air emissions may decrease the amount of CCRs produced by our customers and, as a result, the demand for our services. Faced with the prospect of more stringent regulations, litigation by environmental groups and the relatively low cost of natural gas, an increasing number of utilities are reducing their portfolio of coal-fired power plants. This reduction could increase if the Clean Power Plan, which urges states to substitute electricity generation from higher-emitting coal plants to low-emitting coal and natural gas plants and zero-emitting renewable sources, is upheld in court and retained by the EPA. See “Business—Regulation.”

Increasing requirements generally will increase the cost of doing business and may make coal burning less attractive for utilities. In recent years, multiple companies have announced plans to close coal-fired power plant units or plants, or dropped plans to open new plants, citing the cost of compliance with pending or new environmental regulations and the relatively low cost of natural gas. A reduction in the use of coal as fuel would cause a decline in the production and availability of CCRs, which would adversely affect our Fossil Services and Byproduct Sales offerings and result in reduced revenues. The outcome of these developments cannot be predicted but could have a material adverse effect on our business, results of operation, financial condition and cash flows.

Unsatisfactory service and 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 in a manner that is consistent with our customers’ standards of service as well as applicable laws, rules and permits, which legal requirements are subject to change. Existing and potential customers consider the safety and service record of their third-party service providers to be of high importance in their decision to engage such providers. The power generation industry generally emphasizes safety and service over the lowest cost service provider due to economic and reputational risk associated with operations at their facilities. If one or more accidents were to occur while we are providing services to our customers, or if we were unable to maintain the level of safety and service our customers require, the affected customer may seek to terminate or cancel our services and may be less likely to continue to use our services, which could cause us to lose substantial revenues. Furthermore, our ability to attract new customers may be impaired if they view our safety record or service as unacceptable. In addition, it is possible that we will experience multiple 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 a labor shortage or hire inexperienced personnel to support our staffing needs.

16

A substantial portion of our Maintenance and Technical Services segment consists of the provision of Nuclear Services offerings to nuclear power plants. To the extent there is a decrease in these plants, either due to reduced investment, increased regulation or otherwise, demand for our Nuclear Services offerings could decrease.

U.S. nuclear capacity and electricity generation are expected to decline due to continuing low natural gas prices and the rapid expansion of low-cost renewable energy and new technologies in the U.S., displacing more traditional sources of power, including nuclear power. Public support for nuclear power has also softened because of concerns about safety and environmental issues and new construction costs.

Very few new nuclear reactors are under construction in the U.S., and several nuclear reactors are undergoing decommissioning. In addition, changes in state and federal government subsidies and increased regulation could also negatively impact the nuclear power industry. For instance, the U.S. Nuclear Regulatory Commission has broad authority under federal law to impose safety-related and other licensing requirements for the operation of nuclear generation facilities, and events at nuclear facilities or other events impacting the industry generally could lead to additional requirements and regulations on all nuclear generation facilities and could negatively impact new construction of or continued generation from nuclear power facilities. A lower number of nuclear power facilities in operation and decrease in related maintenance and construction budgets would have a material adverse effect on our business, results of operation, financial condition and cash flows.

Loss of a large customer may adversely affect our revenue and operating results.

During 2017 and 2016, Duke Energy Corporation (“Duke Energy”) accounted for 49% and 68% of our revenues, respectively, through our provision of services at over 10 of their power plants. In 2017, Exelon Corporation (“Exelon”) accounted for 32% of our revenues, through our provision of services at 14 of their sites, representing 23 nuclear reactors. It is likely that we will continue to derive a significant portion of our revenue from a relatively small number of customers in the future. If a major customer fails to pay us, revenue would be impacted and our operating results and financial condition could be materially harmed. Additionally, if we were to lose any material customer, such loss would have a material adverse effect on our business.

We and our customers operate in industries subject to significant environmental regulation, and compliance with changes in, or liabilities under, such regulations could add significantly to the costs of conducting business.

Our operations and the operations of our customers are subject to federal, state and local environmental laws and regulations that, among other matters, impose limitations on the discharge of pollutants into the air and water and establish standards for the treatment, storage and disposal of solid, hazardous and radioactive waste materials, remediation of releases of hazardous substances and reclamation of land. In order to conduct our operations, we and our customers have obtained various federal, state and local environmental permits and must comply with these permits and processes and procedures that have been approved by regulatory authorities. These environmental requirements and any failure to comply could give rise to sanctions, including the cessation of all or part of our operations, or substantial fines and penalties, environmental or reclamation liabilities, which liabilities may be strict, joint and several and damages, including natural resource damages in connection with our sites, customer sites or sites to which we sent wastes, including CCRs and third-party claims. Moreover, changes in environmental laws and regulations occur frequently, and any changes that result in more stringent or costly environmental requirements could require us or our customers to make significant expenditures to attain and maintain compliance. New regulations, any failure to comply with existing regulations or environmental liabilities arising thereunder could have a material adverse effect on our business, results of operation, financial condition and cash flows.

17

Success by environmental groups in convincing the EPA to restrict beneficial uses of CCRs, or to regulate CCRs as hazardous waste, may have an adverse effect on our business.

In April 2015, the EPA published a final rule, Disposal of Coal Combustion Residuals from Utilities, to regulate the disposal of CCRs, including fly ash and bottom ash generated at coal-fired power plants, as non-hazardous waste under Subtitle D of the Resource Conservation and Recovery Act (“RCRA”), as amended, and to distinguish beneficial use of CCRs from disposal, which became effective in October 2015 (the “CCR Rule”). The CCR Rule establishes national minimum criteria for CCR landfills and impoundments consisting of location restrictions, design and operating criteria, groundwater monitoring and corrective action, closure requirements, post-closure care, recordkeeping and reporting and other requirements, and requires closure of facilities unable to comply with these criteria within five to seven years. The CCR Rule has increased the complexity and cost of managing and disposing of CCRs and the remediation of existing ash ponds and landfills. In addition, Congress passed the Water Infrastructure Improvements for the Nation Act (the “WIIN Act”) in December 2016, which, among other things, authorizes state permit programs to manage CCRs in lieu of the CCR Rule. The WIIN Act also gives the EPA the authority to regulate coal ash in states that choose not to implement state permitting programs and in states whose permitting programs are determined to be inadequate by the EPA. On March 1, 2018, the EPA issued a proposed rule that would take further steps under the WIIN Act by granting states with approved CCR permit programs (or the EPA where it is the permitting authority) the ability to set certain alternative performance standards. The proposed rule would also allow CCR to be used during certain closure situations and address certain matters remanded to the EPA by the D.C. Circuit Court of Appeals in June 2016, including clarifying corrective action triggers and requirements, adding boron to the list of constituents triggering corrective action, determining the proper height of woody and grassy vegetation for slope protection, and modifying alternative closure procedures. The proposed rule is designed to allow states or the EPA to incorporate flexibilities into their coal ash permit programs and could be followed by a second proposed rule with a similar purpose by September 2018 and a final rule by June 2019.

Some environmental groups continue to urge the EPA to restrict certain beneficial uses of CCRs, such as in concrete, road base and soil stabilization, alleging contaminants may leach into the environment. The CCR Rule created a definition of “beneficial use” that includes uses in concrete and road base, but changes in the definition could reduce the demand for fly ash and other CCRs which would have an adverse effect on our revenues. Moreover, if the EPA were to regulate CCRs as hazardous waste, we, together with CCR generators, could be subject to environmental cleanup, personal injury and other possible claims and liabilities, which could result in significant additional costs. Any such changes in or new regulations or indemnity obligations could have a material adverse effect on our business, results of operation, financial condition and cash flows.

We may be subject in the normal course of business to judicial, administrative or other third-party proceedings that could interrupt or limit our operations, result in adverse judgments, settlements or fines and create negative publicity.

Individuals, citizens groups, trade associations, community groups or environmental activists may bring actions against us in connection with our operations that could interrupt or limit the scope of our business. Many of these matters could raise difficult and complicated factual and legal issues and are subject to uncertainties and complexities. The timing of the final resolutions to lawsuits, regulatory inquiries and governmental and other legal proceedings is uncertain. Additionally, the possible outcomes of or resolutions to these matters could include adverse judgments or settlements, either of which could require substantial payments or other financial obligations. Any adverse outcome in such proceedings could harm our operations and financial results and create negative publicity, which could damage our reputation and competitive position.

In particular, we are a party to a lawsuit filed by a certain environmental advocacy group challenging North Carolina’s authority to issue certain permits related to our Brickhaven mine site. The North Carolina Superior Court’s decision (which upheld the allowance to reclaim the original site but held that the portions of the permits that allow us to “cut and prepare” an additional portion of the site exceeded the relevant agency’s statutory

18

authority) was reversed and remanded back to the North Carolina Office of Administrative Hearing (“OAH”). If the OAH determines North Carolina exceeded its permitting authority with respect to either the original allowance or the “cut or prepare” portions of the permits or both, such decision, if ultimately upheld, could have an adverse effect on our operations and financial results.

One of our subsidiaries, Allied Power Management, LLC, is the subject of litigation. An adverse outcome in this litigation could have a negative impact on our business, financial condition, results of operations and cash flows.

We may, at any given time, be a defendant in various legal proceedings and litigation arising in the ordinary course of business. In July 2017, APTIM Corp. sued Allied Power Management, LLC and certain of its employees and affiliated entities in the U.S. District Court for the Northern District of Illinois, alleging, among other things, misappropriation of alleged trade secrets and civil conspiracy. APTIM also alleged tortious interference with their contractual and business relations because Exelon, our customer whose business makes up 100% of our Nuclear Services revenues, ended their business relationship with APTIM and started a new business relationship with Allied Power Management, LLC. No schedule for the current phase of the case, and no trial date, has been set. APTIM has not identified its alleged damages. We believe that APTIM’s claims are meritless, and we intend to defend ourselves vigorously. For further information regarding this lawsuit, see “Business—Legal Proceedings.” We cannot predict the outcome of the lawsuit or the amount of time and expense that will be required to resolve the lawsuit. If such litigation were to be determined adversely to our interests, or if we were forced to settle such matter for a significant amount, such resolution or settlement could have a negative effect on our business, results of operations and financial condition.

Increases in labor costs or our ability to find and employ technically skilled labor could impact our financial results.

Our continued success will depend on our ability to attract and retain qualified personnel. Additionally, a significant percentage of our Nuclear Services employees are hired on a seasonal basis as a result of the seasonal (typically every 12 to 24 months) outage maintenance services we provide. We compete with other businesses in our markets for qualified employees. From time to time, the labor supply is tight in some of our markets. A shortage of qualified employees would require us to enhance our wage and benefits packages to compete more effectively for employees, to hire more expensive temporary employees or to contract for services with more expensive third-party vendors. Labor is one of our highest costs and relatively small increases in labor costs per employee could materially affect our cost structure. If we fail to attract and retain qualified employees, control our labor costs or recover any increased labor costs through increased prices we charge for our services or otherwise offset such increases with cost savings in other areas, our operating margins could suffer.

Our employees perform services that involve certain risks, including risks of accident and a failure to maintain a safe work site could result in significant losses.

Safety is a primary focus of our business and is critical to our reputation. Our services can place our employees and others near large equipment, dangerous processes or highly regulated materials, and in challenging environments. Operations in our Environmental Solutions and Maintenance and Technical Services segments involve risks, such as truck accidents, equipment defects, malfunctions and failures and natural disasters, which could potentially result in releases of CCR materials, injury or death of employees and others or a need to shut down or reduce operation of our customers’ facilities while remedial actions are undertaken. We are responsible for safety on the sites where we work and these risks expose us to potential liability for pollution and other environmental damages, personal injury, loss of life, business interruption and property damage or destruction. Unsafe work conditions also have the potential of increasing employee turnover, increasing costs and raising our operating costs. If we fail to implement appropriate safety procedures and/or if our procedures fail, our employees or others may suffer injuries.

19

Although we maintain functional groups whose primary purpose is to implement effective health, safety and environmental procedures throughout our company, the failure to comply with such procedures, client contracts or applicable regulations could subject us to losses and liability and the potential loss of customers. If we were to incur substantial liabilities in excess of any applicable insurance, our business, results of operations and financial condition could be adversely affected.

Work stoppages, union negotiations and other labor problems could adversely affect us.

At March 31, 2018, approximately 1,973 of our employees were covered by collective bargaining agreements, 98% of which are employed in the Nuclear Services operations of our Maintenance and Technical Services segment. A lengthy strike or other work stoppage at any of the facilities where we provide Nuclear Services could have a material adverse effect on us. Additional groups of employees may seek union representation in the future. From time to time, we are subject to unfair labor practice charges, complaints and other legal administrative and arbitration proceedings initiated against us by unions, the National Labor Relations Board or our employees, which could negatively impact our operating results. Negotiating collective bargaining agreements could divert management attention, which could also adversely affect operating results. If we are unable to negotiate acceptable collective bargaining agreements, we may be subject to labor disruptions, such as union-initiated work stoppages, including strikes. Depending on the type and duration of any labor disruptions, our operating expenses could increase significantly, which could adversely affect our financial condition, results of operations and cash flows.

We may be adversely affected by uncertainty in the global financial markets and the deterioration of the financial condition of our customers. If any of our customers suffers financial difficulties affecting their credit risk, our operating results could be negatively impacted.

Our future results may be impacted by the uncertainty caused by an economic downturn, 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 nonpayment or inability to perform obligations owed to us, such as the failure of customers to honor their commitments. Additionally, downturns in U.S. construction could lower the demand for our Byproduct Sales offerings.

Furthermore, we provide service to a number of power generators. To the extent these entities suffer significant financial difficulties, they could be unable to pay amounts owed to us or renew contracts with us at previous or increased rates. The inability of our customers to pay us in a timely manner or pay increased rates, particularly larger accounts, could negatively affect our operating results. 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 or expected revenue to us.

Our historical financial statements may not be indicative of future performance, and our business may be difficult to evaluate because we have a limited operating history.

Due to our limited operating history, comparisons of our current and future operating results with prior periods are difficult. As a result, our limited historical financial performance as the owner of the acquired assets may make it difficult for stockholders to evaluate our business and results of operations to date and to assess our future prospects and viability.

We are, and upon completion of transactions described under “Corporate Reorganization” will be, a recently combined company with a short combined operating history, which makes it difficult for potential investors to evaluate our prospective business or operations or the merits of an investment in our securities. In addition,

20

Charah, LLC and Allied Power Management, LLC, which will become our operating subsidiaries in connection with the transactions described under “Corporate Reorganization,” have not historically operated on a consolidated or combined basis or under the same management team. These factors may make it more difficult for investors to evaluate our business and prospects and to forecast our future operating results. For example, the historical combined financial data may not give you an accurate indication of what our actual results would have been if our corporate reorganization or the formation of our management team had been completed at the beginning of the periods presented or of what our future results of operations are likely to be. Our future results will depend on our ability to efficiently manage our combined operations and execute our business strategy.

Our financial results may fluctuate from quarter to quarter, which may make it difficult to predict our future performance.

Our financial results may fluctuate as a result of the seasonal outage maintenance services we provide as part of our Nuclear Services offerings, along with a number of factors, many of which are outside of our control. Additionally, our other service offerings are subject to quarterly fluctuations from time to time. For these reasons, comparing our financial results on a period-to-period basis may not be meaningful, and our past results should not be relied on as an indication of our future performance. Our future quarterly and annual expenses as a percentage of our revenues may be significantly different from those we have recorded in the past or which we expect for the future. Our financial results in some quarters may fall below expectations. Changes in cost estimates relating to our services, which under percentage-of-completion accounting principles could lead to significant fluctuations in revenue or to changes in the timing of our recognition of revenue from such services, could cause our stock price to fall.

Seasonal and adverse weather conditions adversely affect demand for services and operations.

Weather can have a significant impact on demand as consumption of energy is seasonal, and any variation from normal weather patterns, including due to cooler or warmer summers and winters, can have a significant impact on demand. Adverse weather conditions, such as hurricanes, tropical storms and severe cold weather, may interrupt or curtail our operations or our customers’ operations, and result in a loss of revenue and damage to our equipment and facilities, which may or may not be insured.

We operate in a highly competitive industry and may not be able to compete effectively with larger and better capitalized companies.

While no specific company provides the range of services that we offer, the industries in which we operate are highly competitive and require substantial labor and capital resources. Some of the markets in which we compete or plan to compete are served by one or more large, national companies, as well as by regional and local companies of varying sizes and resources, some of which may have accumulated substantial goodwill in their markets. Some of our competitors may also be better capitalized than we are, have greater name recognition than we do or be able to provide or be willing to bid their services at a lower price than we may be willing to offer. Our inability to compete effectively could hinder our growth or adversely impact our operating results.

We may be unable to make attractive acquisitions or successfully integrate acquired businesses, and any inability to do so may disrupt our business and hinder our ability to grow.

We may from time to time consider opportunities to acquire or make investments in other services and businesses that could enhance our technical capabilities, complement our current services or expand the breadth of our markets. The success of any completed acquisition will depend on our ability to effectively integrate the acquired business into our existing operations. The process of integrating acquired businesses may involve unforeseen difficulties or liabilities and may require a disproportionate amount of our managerial and financial resources. In addition, possible future acquisitions may be larger and for purchase prices significantly higher than those paid for earlier acquisitions. No assurance can be given that we will be able to identify suitable acquisition

21

opportunities, negotiate acceptable terms, obtain financing for acquisitions on acceptable terms or successfully acquire identified targets. Our failure to achieve consolidation savings, to integrate the acquired businesses and assets into our existing operations successfully or to minimize any unforeseen operational difficulties or liabilities could have a material adverse effect on our financial condition and results of operations.

We are vulnerable to significant fluctuations in our liquidity or capital requirements that may vary substantially over time.

Our operations could require us to utilize large sums of working capital, sometimes on short notice and sometimes without assurance of recovery of the expenditures. Environmental liabilities including those arising from various customer contracts and acquisition agreements that require us to indemnify for certain environmental liabilities, litigation risks, unexpected costs or losses resulting from acquisitions, contract initiation or completion delays, political conditions, client payment problems and professional liability or indemnity claims are circumstances or events that could result in significant cash outflows.

We may have difficulty managing growth of our business following the addition of our Nuclear Services offerings, which we provide through Allied Power Management, LLC, to our operations, which could adversely affect our financial condition and results of operations.

The growth of our business could place a significant strain on our financial, technical, operational and management resources. In particular, Allied Power Management, LLC did not operate on a combined basis under our Predecessor until 2017. As we expand the scope of our activities and our geographic coverage through organic growth, there will be additional demands on our financial, technical, operational and management resources. The failure to continue to upgrade our technical, administrative, operating and financial control systems or the occurrences of unexpected expansion difficulties, including the failure to recruit and retain experienced managers and other professionals, could have a material adverse effect on our business, financial condition, results of operations and our ability to successfully or timely execute our business plan.

Restrictive covenants in our debt agreements may restrict our ability to pursue our business strategies. If we fail to comply with the restrictions and covenants in our debt agreements, there could be an event of default under the terms of such agreements, which could result in an acceleration of payment.

Our debt agreements limit our ability to, among other things:

These covenants may also impair our ability to engage in favorable business activities and our ability to finance future operations or capital needs in furtherance of our business strategies. Moreover, the form or level of

22

our indebtedness may prevent us from raising additional capital on attractive terms or obtaining additional financing if needed. A breach of any of these covenants would result in a default under the applicable agreement after any applicable grace periods. A default could result in acceleration of the indebtedness which would have a material adverse effect on us. If an acceleration occurs, it would likely accelerate all of our indebtedness through cross-default provisions and we would likely be unable to make all of the required payments to refinance such indebtedness. Even if new financing were available at that time, it may not be on terms that are acceptable to us.

Our borrowing levels and debt service obligations could adversely affect our financial condition and impair our ability to fulfill our obligations under our Credit Facility and Term Loan.

At March 31, 2018, we had total outstanding indebtedness of approximately $266.1 million, $245.3 million of which relates to our Term Loan. At March 31, 2018, we had no outstanding borrowings and $12.5 million in letters of credit issued for our account under our Credit Facility. Our indebtedness could have important consequences, including the following:

To the extent that new debt is incurred in addition to our current debt levels, the leverage risks described above would increase.

The limitation or the modification of the Price-Anderson Act’s indemnification authority and similar federal programs for nuclear and other potentially hazardous activities could adversely affect our business.

The Price-Anderson Act (“PAA”) provides indemnification to the nuclear industry against liability arising from nuclear incidents at non-military facilities in the U.S. while still ensuring compensation for the general public. The Energy Policy Act of 2005 extended the period of coverage to include all nuclear power reactors issued construction permits through December 31, 2025. Because we provide services to the nuclear energy industry in the ongoing maintenance and modification of its nuclear energy plants, we are entitled to the indemnification protections under the PAA. Although the PAA’s indemnification provisions are broad, it does not apply to all liabilities that we might incur while performing services as a contractor.

If the contractor protection currently provided by the PAA is significantly modified, is not approved for, or does not extend to all of our services, our business could be adversely affected by either our clients’ refusal to retain us for potentially covered services or our inability to obtain commercially adequate insurance and indemnification, or we may be subject to potentially material liabilities in connection with the performance of our services.

Increases in interest rates could adversely impact the price of our shares, our ability to issue equity or incur debt for acquisitions or other purposes.

Interest rates on future borrowings, credit facilities and debt offerings could be higher than current levels, causing our financing costs to increase accordingly. A rising interest rate environment could have an adverse impact on the price of our shares, our ability to issue equity or incur debt for acquisitions or other purposes.

23

We may lose contracts through competitive bidding or early termination.

Many of our contracts are for a specified term and are or will be subject to competitive bidding in the future. Although we intend to bid on additional contracts, we may not always be the successful bidder. In addition, some or all of our customers may terminate their contracts with us prior to their scheduled expiration dates. If we are not able to replace lost revenues resulting from unsuccessful competitive bidding, early termination or the renegotiation of existing contracts with other revenues within a reasonable time period, our results of operations and financial condition could be adversely affected.

We could be precluded from entering into or maintaining permits or certain contracts if we are unable to obtain sufficient third-party financial assurance or adequate insurance coverage.

Our operations in our Environmental Solutions and Maintenance and Technical Services segments sometimes require us to obtain performance or surety bonds, letters of credit or other means of financial assurance to secure our contractual performance. We currently obtain performance and surety bonds from multiple financial institutions; however, if we are unable to obtain financial assurance in the future in sufficient amounts from appropriately rated sureties or at acceptable rates, we could be precluded from entering into additional municipal contracts or from obtaining or retaining landfill management or other contracts or operating permits. Any future difficulty in obtaining insurance could also impair our ability to secure future contracts conditioned upon having adequate insurance coverage.

If we are unable to fully protect the confidentiality of our trade secrets, or if competitors are able to replicate our technology or services, 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 key processes and technology. 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 cannot assure you we will be able to prevent our competitors from employing comparable technologies or processes.

In addition, third parties from time to time may initiate litigation against us by asserting that the conduct of our business infringes, misappropriates or otherwise violates intellectual property rights. If we are sued for infringement and lose, we could be required to pay substantial damages and/or be enjoined from using or selling the infringing products or technology. Any legal proceeding concerning intellectual property could be protracted and costly regardless of the merits of any claim, is inherently unpredictable and could have a material adverse effect on our financial condition, regardless of its outcome.

Additionally, we currently license certain third-party intellectual property in connection with our business, and the loss of any such license could adversely impact our financial condition and results of operations.

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

We depend on digital technologies to process and record financial and operating data and rely on sophisticated information technology systems and infrastructure to support our business, including process control technology. At the same time, cyber incidents, including deliberate attacks, 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 for protecting against cyber security risks may not be sufficient.

24

As the sophistication of cyber incidents continues to evolve, we will likely 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. Additionally, any of these systems may be susceptible to outages due to fire, floods, power loss, telecommunications failures, usage errors by employees, computer viruses, cyber-attacks or other security breaches or similar events. The failure of any of our information technology systems may cause disruptions in our operations, which could adversely affect our revenues and profitability.

Risks Related to This Offering and Our Common Stock

The requirements of being a public company, including compliance with the reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the requirements of Sarbanes-Oxley, may strain our resources, increase our costs and distract management, and we may be unable to comply with these requirements in a timely or cost-effective manner.

As a public company, we will need to comply with laws, regulations and requirements that are new to us, including certain corporate governance provisions of Sarbanes-Oxley, related regulations of the SEC and the requirements of the NYSE, with which we are not required to comply as a private company. Complying with these statutes, regulations and requirements will occupy a significant amount of time of our board of directors and management and will significantly increase our costs and expenses. We will need to:

Furthermore, while we generally must comply with Section 404 of Sarbanes-Oxley for our fiscal year ending December 31, 2019, we are not required to have our independent registered public accounting firm attest to the effectiveness of our internal controls until our first annual report subsequent to our ceasing to be an “emerging growth company” within the meaning of Section 2(a)(19) of the Securities Act. Accordingly, we may not be required to have our independent registered public accounting firm attest to the effectiveness of our internal controls until as late as our annual report for the fiscal year ending December 31, 2023. Once it is required to do so, our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which our controls are documented, designed, operated or reviewed. Compliance with these requirements may strain our resources, increase our costs and distract management, and we may be unable to comply with these requirements in a timely or cost-effective manner.

In addition, we expect that being a public company subject to these rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified individuals to serve on our board of directors or as executive officers. We are currently evaluating these rules, and we cannot predict or estimate the amount of additional costs we may incur or the timing of such costs.

The initial public offering price of our common stock may not be indicative of the market price of our common stock after this offering. In addition, an active, liquid and orderly trading market for our common stock may not develop or be maintained, and our stock price may be volatile.

Prior to this offering, our common stock was not traded on any market. An active, liquid and orderly trading market for our common stock may not develop or be maintained after this offering. Active, liquid and orderly

25

trading markets usually result in less price volatility and more efficiency in carrying out investors’ purchase and sale orders. The market price of our common stock could vary significantly as a result of a number of factors, some of which are beyond our control. In the event of a drop in the market price of our common stock, you could lose a substantial part or all of your investment in our common stock. The initial public offering price will be negotiated between us, the selling stockholders and representatives of the underwriters, based on numerous factors that we discuss in “Underwriting,” and may not be indicative of the market price of our common stock after this offering. Consequently, you may not be able to sell shares of our common stock at prices equal to or greater than the price paid by you in this offering.

The following factors could affect our stock price:

Certain of our Existing Owners will collectively hold a substantial majority of our common stock.

Holders of our common stock will vote together as a single class on all matters presented to our stockholders for their vote or approval, except as otherwise required by applicable law or our certificate of incorporation. Upon completion of this offering (assuming no exercise of the underwriters’ option to purchase additional shares), the Existing Owners will own approximately     % of our common stock.

Although the Existing Owners are entitled to act separately in their own respective interests with respect to their stock in us, the Existing Owners will together have the ability to elect all of the members of our board of directors, and thereby to control our management and affairs. In addition, they will be able to determine the outcome of all matters requiring stockholder approval, including mergers and other material transactions, and will be able to cause or prevent a change in the composition of our board of directors or a change in control of our company that could deprive our stockholders of an opportunity to receive a premium for their common stock as part of a sale of our company. The existence of significant stockholders may also have the effect of deterring hostile takeovers, delaying or preventing changes in control or changes in management, or limiting the ability of our other stockholders to approve transactions that they may deem to be in the best interests of our company.

26

So long as the Existing Owners continue to control a significant amount of our common stock, each will continue to be able to strongly influence all matters requiring stockholder approval, regardless of whether or not other stockholders believe that a potential transaction is in their own best interests. In any of these matters, the interests of the Existing Owners may differ or conflict with the interests of our other stockholders. In addition, BCP and its affiliates may, from time to time, acquire interests in businesses that directly or indirectly compete with our business, as well as businesses that are significant existing or potential customers. BCP and its affiliates may acquire or seek to acquire assets that we seek to acquire and, as a result, those acquisition opportunities may not be available to us or may be more expensive for us to pursue. Moreover, this concentration of stock ownership may also adversely affect the trading price of our common stock to the extent investors perceive a disadvantage in owning stock of a company with a controlling stockholder.

We have identified material weaknesses and a significant deficiency in our internal control over financial reporting and may identify additional material weaknesses in the future or otherwise fail to maintain an effective system of internal controls, which may result in material misstatements of our financial statements or cause us to fail to meet our periodic reporting obligations.

As a public company, we will be required to maintain internal control over financial reporting and to report any material weaknesses in those internal controls, subject to any exemptions that we avail ourselves to under the JOBS Act. For example, we will be required to perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting, as required by Section 404 of Sarbanes-Oxley. We are in the process of designing, implementing, and testing internal control over financial reporting required to comply with this obligation.

We and our independent registered public accounting firm have identified material weaknesses in internal control over financial reporting as of December 31, 2017. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses related to the misapplication of GAAP in accounting for our deferred stock plan in effect in 2016 and ineffective controls over the financial statement close and reporting processes.

We also identified a significant deficiency related to our debt reconciliation process. A significant deficiency is a deficiency, or a combination of deficiencies, in internal control over financial reporting that is less severe than a material weakness, yet important enough to merit attention by those responsible for oversight of the company’s financial reporting.

We are taking steps to remedy these material weaknesses and significant deficiency by establishing more robust processes supporting internal controls over financial reporting, including accounting policies and procedures and our engagement of consultants to assist management in determining and evaluating new accounting positions. We can give no assurance that these actions will remediate this deficiency in internal control or that additional material weaknesses or significant deficiencies in our internal control over financial reporting will not be identified in the future. Our failure to implement and maintain effective internal control over financial reporting could result in errors in our financial statements that could result in a restatement of our financial statements and 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 could have a negative effect on the trading price of our common stock.

BCP and its respective affiliates are not limited in their ability to compete with us, and the corporate opportunity provisions in our amended and restated certificate of incorporation could enable BCP to benefit from corporate opportunities that might otherwise be available to us.

Our governing documents will provide that BCP and its respective affiliates (including portfolio investments of BCP and its affiliates) are not restricted from owning assets or engaging in businesses that

27

compete directly or indirectly with us. In particular, subject to the limitations of applicable law, our amended and restated certificate of incorporation will, among other things:

BCP or its respective affiliates 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. Furthermore, such businesses may choose to compete with us for these opportunities, possibly causing these opportunities to not be available to us or causing them to be more expensive for us to pursue. In addition, BCP and its respective affiliates may dispose of properties or other assets in the future, without any obligation to offer us the opportunity to purchase any of those assets. As a result, our renouncing our interest and expectancy in any business opportunity that may be from time to time presented to BCP and its respective affiliates could adversely impact our business or prospects if attractive business opportunities are procured by such parties for their own benefit rather than for ours.

We have engaged in transactions with our affiliates and expect to do so in the future. The terms of such transactions and the resolution of any conflicts that may arise may not always be in our or our stockholders’ best interests.

We have engaged in transactions and expect to continue to engage in transactions with affiliated companies, as described under the caption “Certain Relationships and Related Party Transactions.” The terms of such transactions and the resolution of any conflicts that may arise may not always be in our or our stockholders’ best interests.

Our amended and restated certificate of incorporation and amended and restated bylaws, as well as Delaware law, will contain provisions that could discourage acquisition bids or merger proposals, which may adversely affect the market price of our common stock.

Our amended and restated certificate of incorporation will authorize our board of directors to issue preferred stock without stockholder approval. If our board of directors elects to issue preferred stock, it could be more difficult for a third party to acquire us. In addition, some provisions of our amended and restated certificate of incorporation and amended and restated bylaws could make it more difficult for a third party to acquire control of us, even if the change of control would be beneficial to our stockholders, including:

28

Our amended and restated certificate of incorporation will designate 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 will provide 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 owed by any of our directors, officers, employees, agents or stockholders to us or our stockholders, (iii) any action asserting a claim against us or any director, officer, employee or agents of ours arising pursuant to any provision of the Delaware General Corporation Law (the “DGCL”), our amended and restated certificate of incorporation or our bylaws, or (iv) any action asserting a claim that is governed by the internal affairs doctrine. 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.

Investors in this offering will experience immediate and substantial dilution of $            per share.

Based on an assumed initial public offering price of $             per share (the midpoint of the price range set forth on the cover of this prospectus), purchasers of our common stock in this offering will experience an immediate and substantial dilution of $             per share in the as adjusted net tangible book value per share of common stock from the initial public offering price, and our as adjusted net tangible book value as of March 31,

29

2018 after giving effect to this offering would be $             per share. This dilution is due in large part to earlier investors having paid substantially less than the initial public offering price when they purchased their shares. See “Dilution.”

We do not intend to pay cash dividends on our common stock, and our Credit Facility and Term Loan place certain restrictions on our ability to do so. Consequently, your only opportunity to achieve a return on your investment is if the price of our common stock appreciates.

We do not plan to declare cash dividends on shares of our common stock in the foreseeable future. Additionally, our Credit Facility and Term Loan place certain restrictions on our ability to pay cash dividends. Consequently, your only opportunity to achieve a return on your investment in us will be if you sell your common stock at a price greater than you paid for it. There is no guarantee that the price of our common stock that will prevail in the market will ever exceed the price that you pay in this offering.

Future sales of our common stock in the public market could reduce our stock price, and any additional capital raised by us through the sale of equity or convertible securities may dilute your ownership in us.

We may issue additional shares of common stock or convertible securities in subsequent public offerings. After the completion of this offering, we will have                 outstanding shares of common stock. This number includes                 shares of common stock that we and the selling stockholders are selling in this offering, but does not include the                 shares of common stock that we and the selling stockholders may sell in this offering if the underwriters’ option to purchase additional shares is fully exercised, which may be resold immediately in the public market. Following the completion of this offering, BCP and its respective affiliates will own                 shares of common stock (assuming an initial public offering price of $         per share of common stock, the midpoint of the price range set forth on the cover page of this prospectus) representing approximately     % (or     % if the underwriters’ option to purchase additional shares is exercised in full) of our total outstanding common stock. All such shares are restricted from immediate resale under the federal securities laws and are subject to the lock-up agreements between such parties and the underwriters described in “Underwriting,” but may be sold into the market in the future. We expect that certain of the Existing Owners will be party to a registration rights agreement with us that will require us to effect the registration of their shares in certain circumstances no earlier than the expiration of the lock-up period contained in the underwriting agreement entered into in connection with this offering. See “Shares Eligible for Future Sale” and “Certain Relationships and Related Party Transactions—Registration Rights Agreement.”

In connection with this offering, we intend to file a registration statement with the SEC on Form S-8 providing for the registration of                  shares of our common stock issued or reserved for issuance under our equity incentive plan. Subject to the satisfaction of vesting conditions and the expiration of lock-up agreements, shares registered under the registration statement on Form S-8 will be available for resale immediately in the public market without restriction.

We cannot predict the size of future issuances of our common stock or securities convertible into common stock or the effect, if any, that future issuances and sales of shares of our common stock will have on the market price of our common stock. Sales of substantial amounts of our 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 common stock.

The underwriters of this offering may waive or release parties to the lock-up agreements entered into in connection with this offering, which could adversely affect the price of our common stock.

We, all of our directors and executive officers, and the selling stockholders have entered or will enter into lock-up agreements with respect to their common stock, pursuant to which they will be subject to certain resale restrictions with respect to the sale or other disposition of our common stock for a period of 180 days following

30

the effectiveness date of the registration statement of which this prospectus forms a part. Morgan Stanley & Co. LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated, at any time and without notice, may release all or any portion of the common stock subject to the foregoing lock-up agreements. If the restrictions under the lock-up agreements are waived, then common stock will be available for sale into the public markets, which could cause the market price of our common stock to decline and impair our ability to raise capital.

We may issue preferred stock, the terms of which could adversely affect the voting power or value of our common stock.

Our amended and restated certificate of incorporation will authorize 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 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 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 common stock.

Taking advantage of the reduced disclosure requirements applicable to “emerging growth companies” may make our common stock less attractive to investors.

We qualify as an “emerging growth company” as defined in the JOBS Act. An emerging growth company may take advantage of certain reduced reporting and other requirements that are otherwise applicable generally to public companies. Pursuant to these reduced disclosure requirements, emerging growth companies are not required to, among other things, comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, provide certain disclosures regarding executive compensation, hold stockholder advisory votes on executive compensation or obtain stockholder approval of any golden parachute payments not previously approved. In addition, emerging growth companies have longer phase-in periods for the adoption of new or revised financial accounting. We would cease to be an emerging growth company if we have more than $1.07 billion in annual revenue, have more than $700 million in market value of our common stock held by non-affiliates, or issue more than $1.0 billion of non-convertible debt over a three-year period.

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. 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.

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. We cannot predict if investors will find our common stock less attractive because we will rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our 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.

31

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

The trading market for our 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 our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. Moreover, if one or more of the analysts who cover our company adversely changes his or her recommendation with respect to our common stock or if our operating results do not meet their expectations, our stock price could decline.
