Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of
Evoqua Water Technologies Corp.
Opinion on Internal Control over Financial Reporting
We have audited Evoqua Water Technologies Corp.’s internal control over financial reporting as of September 30, 2019, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Evoqua Water Technologies Corp. (the Company) maintained, in all material respects, effective internal control over financial reporting as of September 30, 2019, based on the COSO criteria.
As indicated in the accompanying Management’sthis Annual Report on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of ATG UV, which is included in the 2019 consolidated financial statements of the Company and constituted $4.1 million and $1.1 million of total and net assets, respectively, as of September 30, 2019 and $4.9 million and $1.0 million of revenues and net income, respectively, for the year then ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of ATG UV.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of September 30, 2019 and 2018, the related consolidated statements of operations, comprehensive income (loss), changes in equity and changes in cash flows for each of the three years in the period ended September 30, 2019, and the related notes and the financial statement schedule listed in the Index at Item 15(a)1 to the consolidated financial statements and our report dated November 25, 2019 expressed an unqualified opinion thereon.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.  
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of


the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Evoqua Water Technologies Corp. (referred to herein as the “Company”“the Company,” “Evoqua,” “we,” “us,” or “EWT”“our”) was incorporated on October 7, 2013. On January 15, 2014, Evoqua acquired the Water Technologies Corp., acquired through its wholly owned entities, EWT Holdings II Corp. and EWT Holdings III Corp. (a/k/a Evoqua Water Technologies), all of the outstanding shares of Siemens Water Technologies, a group of legal entity businessesbusiness unit formerly owned by Siemens AG (“Siemens”). The stock purchase closed on January 15, 2014 and was effective January 16, 2014 (the “Acquisition”). The stock purchase price, net of cash received, was approximately $730,577. On November 6, 2017, the Companywe completed itsour initial public offering (“IPO”), pursuant to which an aggregate of 27,777 shares ofand our common stock were sold,began trading on the New York Stock Exchange (the “NYSE”) on November 2, 2017 under the ticker symbol “AQUA.”

We are a leading provider of mission-critical water and wastewater treatment solutions, offering a broad portfolio of products, services, and expertise to support customers across various end markets. We are headquartered in Pittsburgh, Pennsylvania, with locations across ten countries. We have a comprehensive portfolio of differentiated, proprietary technologies offered under market‑leading and well‑established brands. Our core technologies are primarily focused on removing impurities from water, rather than neutralizing them through the addition of chemicals. We have worked to protect water, the environment, and our employees for over 100 years. As a result, we have earned a reputation for quality, safety and reliability and are sought out by our customers to solve the full range of their water treatment needs.

We provide solutions across the entire water cycle. The water cycle begins with influent water, which 8,333 were soldis sourced from rivers, lakes, and other sources. We treat influent water for use in a wide variety of industrial, commercial, and municipal applications, including use as process water in manufacturing, power generation and other industrial applications, use as ingredient water in the production of food, beverage, and other goods, use in laboratory testing, use by commercial aquatic facilities, and to produce safe drinking water. After the Companywater is used it is considered effluent water, and 19,444 were soldwe treat it to remove impurities so that it can be discharged safely back into the environment or reused for industrial, commercial, or municipal applications.

Customers
Our customers span a diverse range of end markets, including general manufacturing, healthcare, pharmaceuticals, biotech, power, microelectronics, chemical processing, food and beverage, municipal drinking water and wastewater, aquatics, refining and marine end markets. We sell directly to end users in these end markets and also to intermediaries, such as OEMs, system integrators, regional distributors, and engineering firms.Our business is not dependent on any single customer or end market. During the year ended September 30, 2021, no single customer accounted for more than 1.3% of our revenue, and our top ten customers accounted for approximately 7.4% of our revenue.

We provide products, services, and solutions to federal, state and local government customers both directly and indirectly as a supplier to general contractors. Many of our government contracts contain a termination for convenience clause, regardless of whether we are the prime contractor or a subcontractor. Upon a termination for convenience, we are generally able to recover the purchase price for delivered items and reimbursement of allowable work in process costs.
Suppliers
We maintain a cost-effective and diversified procurement program focused on supply chain continuity and customer fulfillment, utilizing strong relationships with strategic suppliers across key commodities. The top materials in our supply chain include chemicals, membranes, resin, metal fabrications, carbon, and electrical components. Procurement strategy within the project environment is focused on ensuring our ability to meet individual customer needs, with particular focus on more complex installation projects. We seek to in-source products that align with our existing manufacturing core competencies and that enable us to provide our customers with the highest level of value. Our diversified supply base spans across multiple suppliers and geographies, which we believe enables us to be cost-effective and responsive while also embracing our sustainability objectives.
Seasonality
Our business may exhibit seasonality resulting from our customers’ increasing demand for our products and services during the IPOspring and summer months as compared to the fall and winter months. For example, we experience increased demand for our odor control product lines and services in the warmer months which, together with other factors, typically results in improved performance in the second half of our fiscal year. Inclement weather and extreme weather events, such as hurricanes, winter storms, droughts, and floods, can also have varying impacts on our business. Certain events may cause customer shutdowns that prevent or defer our performance of services or sale of equipment, while other events may drive increased demand for our products and services, particularly emergency response services. As a result, our results from operations may vary from period to period.
Sales and Marketing
Our ISS segment markets its offerings through a direct sales and service team, which is organized geographically and by end market and is complemented by an inside sales force, field sales engineers and a growing e-commerce platform. Our key end markets served by our ISS segment are general manufacturing, healthcare, pharmaceuticals, biotech, power, microelectronics, chemical processing, food and beverage, and refining. As of September 30, 2021, our ISS segment included approximately 350 employees in sales and marketing roles and a services network of approximately $137,605. The Company used950 employees in field service and application engineering roles.

Our APT segment markets its offerings primarily through indirect channels to serve the global market or through our ISS segment’s sales organization as part of broader solutions. APT maintains relationships with OEMs, system integrators, sales representatives, regional distributors, engineering firms, and various other end users through our direct technical sales force to drive adoption of our offerings. APT maintains a portion of these proceedscomprehensive municipal representative network in the U.S., providing us with an opportunity to repay $104,936 of indebtedness (including accrued and unpaid interest) under EWT III’s senior secured first lien term loan facilityinfluence specifications and the remainderbasis of design for general corporate purposes. new treatment facilities. As of September 30, 2021, we had active relationships with more than 240 distributors and sales representatives.
Growth Opportunities
We believe the global water market is well positioned to grow, supported by a variety of anticipated secular trends that will drive demand for clean water across a multitude of industrial, commercial, and municipal applications. These secular trends include water and climate risk, health and safety, connectivity and overall economic growth. Less predictable water availability and increased water scarcity are among the anticipated effects of climate change. Accessing water from current sources is becoming increasingly challenging, so the development of non-traditional sources of water and recycle and reuse technologies will be required.
The Company did not receive any proceedssupply of clean water could be further impacted by factors including aging water infrastructure within North America and increased levels of water stress from seasonal rainfall, inadequate water storage options or treatment technologies. As global consumption patterns evolve and water shortages persist, we expect demand for solutions and services will continue to increase. Additionally, a decrease in the salesupply of sharesclean water, as well as a heightened focus on environmental sustainability across various end markets, may increase the demand for closed-loop solutions that allow recycling and reuse of effluent water for certain applications. In order to position the company to meet this demand, key elements of our growth strategy include:

Provide a higher value-add service-based business model to our customers.Many of our customers require water that meets a particular specification to facilitate the operation of their own businesses. Our goal is to provide reliable water treatment solutions by combining our products and technologies with our extensive service and distribution capabilities, enabling our customers to outsource their water treatment needs to us and focus on their core businesses. Our outsourced water offerings are high value add solutions utilizing our owned assets to generate service revenue. An example is our Water One® service platform, which uses digitally connected remote monitoring technology to provide customers with predictive and proactive service, usage-based pricing, and simplified billing.

Drive margin expansion and cash flow improvements through continued focus on strategic pricing, operational excellence, execution and cost savings initiatives.During the selling shareholders. On November 7, 2017,year ended September 30, 2021, we deployed a more robust strategic pricing program to focus on efficient and effective price increase implementation with the selling shareholders sold anobjective of ensuring more immediate recovery of increased supply chain costs and capturing appropriate value for our innovations. Dedicated resources and systems have been put in place to institutionalize these practices. In parallel, we are pursuing several discrete initiatives that, if successful, we expect could result in additional 4,167 sharescost savings over the next two years. These initiatives include our continuing supply chain improvement program to consolidate and manage global spending, our improved logistics and transportation management program, capturing benefits of common stockour Water One® service platform and further optimizing our engineering cost structure, our global shared services organization and our sales, inventory and operations planning, including footprint rationalization. Furthermore, as a result of significant investments we have made in our footprint and facilities, we believe we have the exercisecapacity to support our planned growth without commensurate increases in full byfixed costs.

Continue to expand our capabilities for the underwriterstreatment of increasingly complex emerging contaminants. Emerging contaminants such as PFAS, PFOA, selenium, micro-plastics and many others, may present global health risks if not properly removed from drinking water, process water and wastewater. We believe we have one of the leading portfolios of water treatment products and solutions to remove emerging contaminants from water including granular activated carbon, ion exchange resin, reverse osmosis, and advanced oxidation processes. In addition, we have an optionextensive service branch network, located predominantly in the United States, as well as a large fleet of mobile assets to purchase additional shares. respond quickly to customers’ water treatment needs.

Continue to evaluate and pursue accretive acquisitions to add new technologies, attractive geographic regions and end markets.As a complement to our organic growth initiatives, we view acquisitions as a key element of our overall growth strategy. We target acquisitions that we believe will enable us to accelerate our growth in our current addressable market, new geographies, and new end market verticals. Our existing customer relationships, channels to market and ability to rapidly commercialize technologies provide a strong platform to drive growth in the businesses we acquire. To capitalize on these opportunities, we have built an experienced team dedicated to mergers and acquisitions that has helped us expand our vertical markets and geographic reach and enhance our portfolio of technologies.

During the year ended September 30, 2021, we completed the following acquisitions:

On March 19, 2018,December 17, 2020, we acquired the Company completed a secondary public offering, pursuant to which 17,500 sharesindustrial water business of common stock were sold by certain selling shareholders.Ultrapure & Industrial Services, LLC (“Ultrapure”) for $8.7 million cash paid at closing. On March 21, 2018, the selling shareholders soldApril 1, 2021, we paid an additional 2,625 shares of common stock$0.3 million as a result of net working capital adjustments. Ultrapure, based out of Texas, provides customers across multiple end markets with a variety of water treatment products and services, including service deionization, reverse osmosis, UV, and ozonation. Ultrapure will strengthen our service capabilities in the exerciseHouston and Dallas markets and is a part of our ISS segment.

On April 1, 2021, we acquired the assets of Water Consulting Specialists, Inc (“WCSI”) for $12.0 million cash paid at closing. WCSI is a leader in fullthe design, manufacturing, and service of industrial high-purity water treatment systems. The acquisition strengthens our portfolio of high-purity water treatment systems and provides the opportunity to further expand its digitally enabled solutions and services in key industrial markets. WCSI is a part of our ISS segment.

Research, Development and Engineering
We utilize a disciplined, stage-gate process consisting of development, field test, commercialization, supply chain and sourcing decisions to identify and develop new technologies for commercialization.We also partner with leading universities, research centers and other outside agencies to explore potential developments.

As of September 30, 2021, our global research, development, and engineering footprint included seven facilities located in the U.S., the United Kingdom, the Netherlands, Germany and India, staffed with managers, scientists, researchers, engineers, and technicians. In October 2021, we opened a new Sustainability and Innovation Hub in Pittsburgh, Pennsylvania.This 18,000 square-foot facility houses a hands-on demonstration and training area, a pilot testing environment, and a laboratory to grow our analytical and feasibility study capacity.We expect this facility to advance our research and development capabilities and enable further development of sustainable water treatment technologies.Our total expected investment in this facility is approximately $5.6 million, of which $3.5 million has been recognized as of September 30, 2021.

Intellectual Property
Our intellectual property and proprietary rights are important to our business, but we do not believe our business as a whole to be materially dependent on any single patent, trade secret or trademark. As of September 30, 2021, we have approximately 1,600 granted or pending patents (after giving effect to patents transferred as a result of acquisitions and dispositions to date). We undertake to strategically and proactively develop our intellectual property portfolio by pursuing patent protection, obtaining copyrights and registering our trademarks in the U.S. and in foreign countries. We currently rely primarily on patent, trademark, copyright and trade secret laws, and control access to our intellectual property through license agreements, confidentiality procedures, nondisclosure agreements with third parties, employment agreements and other contractual rights, to protect our intellectual property rights.
10


Competition
Our industry is highly fragmented and includes a number of regional and niche offering focused competitors. Competition is largely based on product performance and reliability, pricing of products and services, ability to provide service and support, application expertise and process knowledge, brand reputation, energy and water efficiency, product compliance with regulatory and environmental requirements, product lifecycle cost, scalability, timeliness of delivery, the proximity of service centers to customers and the effectiveness of distribution channels. Within each of our segments and the various businesses that comprise them, we compete with a variety of companies, but we do not consider any single company to be a key competitor to our business as a whole.
Backlog
Backlog represents the expected future revenue for unfulfilled and remaining performance obligations for capital projects where neither Evoqua nor the customer can terminate the contract without penalty. As of September 30, 2021, our backlog was approximately $275.6 million.

Human Capital Resources
We believe our talent within the organization is key to our long-term success. Our human capital management philosophy and objectives focus on creating a high-performance culture in which employees are highly enabled, empowered, and accountable to deliver results. As of September 30, 2021, we had approximately 4,000 employees. Of these employees, approximately 59% were full-time salaried staff and the remaining employees consisted of a mix of full-time and part-time hourly workers. Approximately 75% of our employees work in our U.S. operations and approximately 25% work in foreign operations. None of our facilities in the U.S. or Canada are covered by collective bargaining agreements. As is common in Germany and the Netherlands, our employee populations there are represented by works councils.

The health, safety and well-being of our employees is our top priority.Fostering a safe working environment is critical to our ability to attract and retain talent and to earn and keep the trust of our customers.In order to do so, our Environmental, Health and Safety team conducts monthly safety reviews at the executive level, reviews each recordable accident with our CEO and leadership team, conducts quarterly reviews with our Board of Directors, routinely reviews key performance indicators, and conducts regular facility audits.Every employee is empowered to stop work when they have a concern or see the potential for injury.Throughout the COVID-19 pandemic, we have remained focused on protecting the health, safety and well-being of our employees and managing the business to preserve our workforce.We have implemented safety plans and protocols following guidance from the Centers for Disease Control, World Health Organization, and other federal, state, local and international regulations, and we continue to evolve our corporate and site-specific crisis management teams to actively manage and ensure compliance with these plans and protocols.

We are currently operating in an extremely challenging talent market. Market hiring surges, increased attrition and shifting work expectations have significantly impacted the attraction and retention of talent, creating a hyper-competitive global marketplace. We understand that our long-term success will require a differentiated, targeted approach to talent attraction and retention. In response to these challenges, we took a number of actions in 2021 in an effort to enhance our ability to attract and retain diverse talent.

We learned through employee surveys, stay interviews, and exit survey data that career development and recognition were two key factors that might influence our employees to consider leaving the organization. In response, we developed six enterprise-wide career paths designed to help employees in certain roles establish career development plans.We also put in place processes to advance our internal talent placements, ensuring cross-segment and cross-functional internal talent moves are occurring across the organization, to help employees achieve the objectives of their development plans. We plan to launch a global recognition program in 2022 to ensure the accomplishments of our employees are better acknowledged.

11


We recently launched workstreams in two key focus areas: total compensation, with a deeper focus on sign-on and referral bonuses, and branding and advertising within the talent market, with a heightened focus on Inclusion and Diversity and Sustainability.

We launched our flexible work approach that balances the benefits of working remotely with the experience of working on-site.

Our Inclusion & Diversity (ID) strategy is also critical to our long-term success, and we continuously strive to improve the diversity of our workforce through inclusive practices and actions. Through our ID action plan, we launched a Business Resource Group called the Evoqua Inclusion Network (EIN) in September 2021, which is tasked with identifying action opportunities that promote inclusion and minimize unconscious bias. Specific actions taken to date include the dissemination to all global employees of an unconscious bias learning program, enhancement of our benefits offerings with our flexible work approach, updating our internal and external branding materials focusing on ID, and implementing recruiting strategies to better attract diversity, such as blind resumes and diverse interview panels.

We are working to improve gender diversity at all levels of the business through our ID strategy and action plan. As of September 30, 2021, women make up approximately 20% of our global employee population and approximately 15% of our leadership roles, defined as director level and above. In 2021, we saw an increase of approximately 23% in gender diversity in leadership roles within the organization, and we have seen an increase of approximately 95% in gender diversity in leadership roles from September 30, 2018 to September 30, 2021.

We embrace inclusion and diversity not only in our employment practices but also in our director selection. Since October 2018, our Corporate Governance Guidelines have provided that diverse candidates, including women and minorities, must be included in each pool of candidates from which we select new directors, otherwise known as the “Rooney Rule.” Forty percent of our current Board members self-identify as diverse, in terms of race, ethnicity or gender, including three of the four directors that have joined our Board since our initial public offering.

Government Regulation and Environmental Matters
We are subject to extensive and varied laws and regulations in the jurisdictions in which we operate, including those relating to anti‑corruption and trade, anti-money laundering, import and export compliance, antitrust, data security and privacy, employment, workplace safety, product safety, public health and safety, environmental compliance, intellectual property, transportation, zoning, and fire codes. Our policies mandate compliance with all applicable laws and regulations, and we operate our business in accordance with standards and procedures designed to comply with these laws and regulations.

The geographic breadth of our facilities and the nature of our operations subject our operations and products to extensive environmental, health and safety laws, regulations, and permits, domestically and internationally, at national, state, and local levels throughout the world. Such laws, regulations and permits relate to, among other things, air emissions, potable and non-potable water and wastewater treatment, wastewater discharge, the generation, handling, storage, use, transport, treatment and disposal of non-hazardous and hazardous materials and wastes, product safety and workplace health and safety. These laws and regulations impose a variety of requirements and restrictions on our operations and the products we distribute, and they could increase our cost of producing certain products or make certain products obsolete or less attractive in the marketplace. The failure by us to comply with these laws and regulations could result in fines, penalties, enforcement actions, third party claims, damage to property or natural resources, personal injury claims, requirements to investigate or cleanup property or to pay for the costs of investigation or cleanup or regulatory or judicial orders

requiring corrective measures, including the installation of pollution control equipment, remedial actions or the pulling of products from the market, and could negatively impact our reputation with customers.

Many of the customers that we serve are subject to the same or similar environmental, health and safety laws and regulations. Compliance with these laws by our customers could result in increased or decreased demand for our products and services.

Specific laws and regulations that may affect our operations or demand for our products and services include, among others, the following.

The federal Clean Water Act (the “CWA”) and comparable state, local and foreign laws that regulate the discharge of pollutants into streams and other waters.These laws may limit the quantity of pollutants in water discharges and require persons to apply for and obtain permits and conduct sampling and monitoring, and in some cases, treat the water.Changes in limits on the quantity of pollutants and the types of pollutants under the CWA and comparable state, local or foreign laws could affect demand for our products or services or create liability for us as the result of contamination in water we treat.

The federal Safe Drinking Water Act (the “SDWA”) and comparable state, local and foreign laws that set standards for drinking water quality and protect sources of public drinking water. The U.S. Environmental Protection Agency (the “EPA”) has issued standards for microorganisms, disinfectants, disinfection byproducts, inorganic chemicals, organic chemicals, and radionuclides.Changes in the SDWA or comparable state, local or foreign standards, including the addition of newly-regulated contaminants, could affect demand for our products and services and/or result in the obsolescence of our products or lead to an interruption or suspension of our operations. Additionally, increased public awareness of the presence and human health impacts of manmade chemicals and naturally occurring contaminants in drinking water may increase demand for our municipal service offerings. Correspondingly, if stringent laws or regulations are delayed or are not enacted, or repealed or amended to be less stringent, or enacted with prolonged phase‑in periods, or not enforced, then demand for our products and services may also be reduced.

The Resource Conservation and Recovery Act (“RCRA”) and comparable state, local and foreign laws that regulate substances designated as hazardous waste.Our operations involve the generation, handling, storage, use, transport, treatment and disposal of non-hazardous and hazardous materials and wastes.Changes in materials covered or treatment, storage, and disposal requirements under RCRA and comparable state, local or foreign standards could result in increased operating costs or require additional investment in our covered facilities.

The Comprehensive, Environmental Response, Compensation, and Liability Act (“CERCLA”) and comparable state, local and foreign laws.The Company has been subject to claims under CERCLA, which can impose joint and several liability on “potentially responsible parties” for costs of investigation and remediation and for natural resource damages, without regard to fault or the legality of the original conduct, on certain classes of persons with respect to the release into the environment of specified substances, including, under CERCLA, those designated as “hazardous substances.”

The Toxic Substances Control Act (the “TSCA”), the Federal Insecticide, Fungicide and Rodenticide Act (the “FIFRA”), and comparable state, local and foreign laws that regulate the manufacture and/or distribution of certain chemical substances and/or disinfection equipment.These laws may require ongoing submissions to the EPA or state environmental agencies, including, but not limited to, information on the chemistry and toxicology of the chemical substance or products, registrations, notification, and other requirements before such products can be manufactured, distributed, or sold. Changes in these laws could affect demand for our products and services, increase our cost of operations, result in the obsolescence of our products or lead to an interruption or suspension of our operations.

Item 1A. Risk Factors
The following risks and uncertainties could materially adversely affect our business, financial condition, results of operations or prospects. Although the risks are organized by headings and each risk is described separately, many of the risks are interrelated. While we believe we have identified and discussed below the key risk factors affecting our business, there may be additional risks and uncertainties that are not presently known or that are not currently believed to be significant that may adversely affect our business, financial condition, results of operations or prospects in the future. Any one or more of such factors could directly or indirectly cause our actual results of operations and financial condition to vary materially from past or anticipated future results of operations and financial condition.
Business and Operational Risks
The COVID-19 pandemic has adversely affected, and may continue to adversely affect, our business, financial condition, results of operations and prospects.
The COVID-19 pandemic, the resulting global economic slowdown, and the reopening of global economies that has followed have created a number of macroeconomic challenges that have impacted our business, including volatility and uncertainty in business planning, disruptions in global supply chains, material, freight and labor inflation, shortages of and delays in obtaining certain materials and component parts, and labor shortages.To date, the pandemic has negatively impacted sales volume across our business, due primarily to customer site access restrictions, temporary customer site closures, and temporary delays in annual maintenance activities by customers in certain end markets. Further, certain of our customers have restricted access to their sites such that only our vaccinated employees may enter such sites, which may delay our timely provision of services to them.

The COVID-19 pandemic has also heightened risks associated with our operations. Our service technicians enter high-risk areas such as hospitals and testing laboratories, putting them at greater risk of exposure to the virus. An outbreak among our service technician population or an outbreak among employees at any of our manufacturing facilities, which may require us to suspend or reduce operations at that facility, could have a material adverse effect on our business, financial condition, results of operations and prospects. Additionally, a large number of our employees continue to work remotely, resulting in increased cyber-security risk.
Further, the Occupational Safety and Health Administration, acting at the direction of the President of the United States, published a Temporary Emergency Standard requiring certain companies to vaccinate their employees or test those who are not vaccinated at least once per week. This could impact employee retention or increase our costs of operation. If we
14


are unable to respond to and manage the impact of these events, our business and results of operations may be adversely affected. Additionally, if we are unable to comply with these requirements, we could face enforcement actions or financial penalties.

The duration and severity of the pandemic remain uncertain and cannot be predicted. If COVID-19 and its variants continue to spread, or if the duration of the disruptions caused by the underwriterspandemic is further prolonged, our business, financial condition, results of operations or prospects could be materially adversely affected. Even after the COVID-19 outbreak has subsided, we may continue to experience impacts to our business and our financial results in subsequent periods due to the pandemic’s impact on the global economy and on certain markets that we serve. COVID-19 and future public health crises and pandemics may also affect our operating and financial results in a manner that is not presently known to us or not presently considered to be a significant risk to our operations. The impact of the COVID-19 pandemic may also have the effect of heightening many of the other risks and uncertainties described in this “Risk Factors” section.

Our financial results depend on successful project execution and may be adversely affected by cost overruns, failure to meet customer schedules or other execution issues.
A significant portion of our revenue is derived from large projects that are technically complex and may occur over multiple years. These projects are subject to a number of significant risks, including project delays, cost overruns, changes in scope, unanticipated site conditions, design and engineering issues, incorrect cost assumptions, increases in the cost of materials and labor, health and safety hazards, third party performance issues, weather issues and changes in laws or permitting requirements. If we are unable to manage these risks, we may incur higher costs, liquidated damages, and other liabilities to our customers, which may decrease our profitability and harm our reputation. Many of these projects require us to contract with engineering, procurement, and construction firms (“EPCs”). If an optionEPC that we have commissioned to purchase additional shares. The Company didbuild a new project defaults or fails to fulfill its contractual obligations, we could face significant delays, cost overruns and liabilities.Our continued growth will depend in part on executing a higher volume of large projects, which will require us to expand and retain our project management and execution personnel and resources.

Our business could be adversely affected by material, freight, and labor inflation and other manufacturing and operating cost increases and commodity availability constraints.
Certain commodities and materials used in our operations, including, but not receive any proceedslimited to, steel, caustic, carbon, calcium nitrate, and iridium, are subject to significant price fluctuations. Volatility in the market price and availability of these materials has a direct impact on the cost of operating our business. Our operating costs are also impacted by fluctuations in the cost of energy and related utilities, freight, and labor. We have experienced material, freight, and labor cost increases, and we have taken actions to mitigate the impact of these cost increases through price increases, cost savings projects, and sourcing decisions, as well as through strategic productivity improvements. If we are unable to offset these cost increases, it will adversely impact our gross profit, gross margin and operating profit. In addition, many of our contracts are long‑term in nature, and our failure to accurately project operating costs or negotiate or enforce price escalation provisions in our long‑term contracts could have a material adverse effect on our business, financial condition, results of operations or prospects.

Reliance on third party shipping companies may impact our ability to execute projects on time and within budget.

We rely upon various means of transportation through third parties, including shipments by air, sea, rail, and truck, to deliver products to our facilities from the salevendors and from our facilities to our customers, as well as for direct shipments from vendors to customers. Factors beyond our control, many of shareswhich have been caused or exacerbated by the selling shareholders.COVID-19 pandemic, including labor shortages and capacity constraints in the transportation industry, container shortages, port congestion, disruptions to the national and international transportation infrastructure, fuel shortages, and transportation cost increases (such as increases in fuel costs or port fees), have impacted and could further impact our ability to execute projects or ship products to our customers on time and within budget, which could harm our reputation and have a material adverse effect on our business, financial condition, results of operations and prospects. Generally, we have been ableto pass on the majority of shipping and related charges to our customers, but there can be no assurance that we will be able to do so into the future. Failure to do so may adversely impact our gross profit and gross margin.

15


We may incur liabilities to customers as a result of warranty claims or failure to meet performance guarantees, which could reduce our profitability.
Our customers typically require product warranties as to the proper operation and conformance to specifications of the products we manufacture or install, and performance guarantees as to any effluent water produced by our equipment and services. Failure of our products to operate properly or to meet specifications of our customers or our failure to meet our performance guarantees may increase costs by requiring additional engineering resources and services, replacement of parts and equipment and frequent replacement of consumables or monetary reimbursement to a customer or could otherwise result in liability to our customers. We have in the past received warranty claims, and we expect to continue to receive them in the future. There are significant uncertainties and judgments involved in estimating warranty and performance guarantee obligations, including changing product designs, differences in customer installation processes and failure to identify or disclaim certain variables in a customer’s influent. To the extent that we incur substantial warranty or performance guarantee claims in any period, our reputation, earnings, and ability to obtain future business could be materially adversely affected.
Our inability to meet our own and our customers’ safety standards could have a material adverse effect on our sales and profitability.
Maintaining a strong and reliable reputation for safety is critical to our business. Many of our customers actively monitor and review our company‑wide safety record. Risks arising from unsafe products or unsafe performance by our employees include, among other things, personal injury or death caused by our products or occurring in our facilities, the destruction of customer or third‑party property during the execution of a service arrangement or due to the malfunction of our products, delays in or suspension of service or the failure to timely deliver our products. Workplace accidents or near-accidents, product-related accidents, or the failure to follow our own or our customers’ safety policies could damage our reputation or our customers’ perception of our safety record, which could have a material adverse impact on demand for our products and services, result in additional costs to our business or the loss of customers, result in litigation against us or increase government or regulatory oversight over us.

Failure to effectively treat emerging contaminants could result in material liabilities.
A number of emerging contaminants might be found in water that we treat, including PFAS, PFOA, selenium, micro-plastics, hazardous chemicals, or pathogens that may cause a number of illnesses, including cholera, typhoid fever, cancer, giardiasis, cryptosporidiosis, amoebiasis and free-living amoebic infections. Such contaminants or pathogens may be found in the environment, and, as a result, there is a risk that they could be present in water treated using our systems or products. In applications where treated water enters the human body, illness and death may result if contaminants or pathogens are not eliminated during the treatment process. In particular, contamination could result from failing to properly treat reusable products before they are distributed to our customers, or from actions taken by our customers or other third parties using our products, which could result in material liability. The Businesspotential impact of a contamination of water treated using our products, services or solutions is difficult to predict and could lead to an increased risk of exposure to product liability claims, increased scrutiny by federal and state regulatory agencies and negative publicity. Further, an outbreak of disease in any one of the municipal markets we serve could result in a widespread loss of customers across other such markets.
EWT providesOur future growth is dependent upon our ability to continue to develop or acquire new products, services and solutions that allow us to compete successfully in our markets.

We offer our products, services, and solutions in highly competitive markets. Our future growth depends upon our ability to (i) identify emerging trends in our target end markets, (ii) develop and maintain a wide range of competitive and appropriately priced products, services and solutions, (iii) enhance and differentiate our products from those of our competitors, (iv) develop and drive commercial acceptance of new products quickly and cost‑effectively, (v) ensure that our products, services and solutions remain cost‑competitive, even when faced with rising commodity costs, (vi) attract, develop and retain individuals with the requisite technical expertise and understanding of customers’ needs to develop and sell new technologies and products, and (vii) execute projects in a cost-effective manner according to the schedules required by our customers.
16



Our growth strategy includes growth through acquisitions, and we may not be able to identify suitable acquisition targets or otherwise successfully implement our growth strategy.
Acquisitions have historically been a significant part of our growth strategy, and we expect to continue to grow through acquisitions in the future. We may not be able to identify suitable candidates, negotiate appropriate or favorable acquisition terms, obtain financing that may be needed to consummate such transactions or complete proposed acquisitions. There is significant competition for acquisition and expansion opportunities in our businesses.
Acquisitions require significant time and attention from management and other key personnel, which may result in attention being diverted from the operation of our existing business.Other risks associated with our acquisition strategy include ineffective integration of an acquisition, as further described below, inaccurately estimating a target’s financial condition or risk profile, failure to achieve planned synergies, litigation relating to an acquisition, failure to receive required regulatory approvals or such approvals being delayed or restrictively conditional, potentially insufficient internal controls over financial activities or financial reporting at an acquired entity that could impact our existing business on a combined basis, and an adverse impact on our existing business resulting from an acquired business that historically had a higher risk tolerance or whose personnel fail to comply with our existing policies.

We may have difficulty operating or integrating any acquired businesses, assets, or product brandslines profitably, or in successfully implementing our growth strategy.
The anticipated benefits from any potential acquisitions may not be achieved unless the operations of the acquired business assets or product lines are successfully integrated in an efficient, effective, and advancedtimely manner. The integration of our acquisitions will require substantial attention from management and operating personnel to ensure that the acquisition does not disrupt any existing operations or affect our customers’ opinions and perceptions of our services, products, or customer support. Risks associated with integration of an acquisition include failure of an acquired business to perform to our expectations, our failure to integrate it appropriately and on a timely basis, our failure to realize anticipated synergies and cost savings, our failure to preserve the customer relationships and retain key employees of an acquired business and difficulties, inefficiencies or cost overruns in integrating and assimilating the organizational cultures, operations, technologies, data, services and products of the acquired business with ours.
The process of integrating acquired businesses, assets and product lines could cause the interruption of, or delays in, the operation of our existing business, which could have a material adverse effect on our business, financial condition, results of operations or prospects. Acquisitions also place a burden on our information, financial and operating systems and our employees and management. If we are unable to manage our growth effectively, we may spend time and resources on such acquisitions that do not ultimately increase our profitability or that cause loss of, or harm to, relationships with employees and customers.
We may not achieve some or all of the expected benefits of our restructuring actions, which may materially adversely affect us.
We have taken a number of restructuring actions in recent years in an effort to better serve the needs of our customers worldwide, achieve cost savings and operational efficiencies, and position ourselves for improved long-term growth and profitability. Achieving the expected cost savings and efficiencies will be subject to significant economic, competitive, and other uncertainties, some of which are beyond our control, and we may not be able to obtain the cost savings and benefits that we currently anticipate in connection with these restructuring actions. Our assumptions may not be accurate, and we may not be able to operate in accordance with our plans, which may cause us to incur additional restructuring charges. These types of initiatives could yield unintended consequences such as distraction of our management and employees, business disruption and unforeseen costs, attrition beyond any planned reduction in workforce, inability to attract or retain key personnel and reduced employee productivity, which could materially adversely affect our business, financial condition, and results of operations. The successful implementation and execution of our restructuring actions are critical to achieving our expected cost savings as well as effectively competing in the marketplace and positioning us for future growth. If our restructuring actions are not executed successfully, it could have a material adverse effect on our business, financial condition, results of operations, and prospects.

Delays in enactment or repeals of environmental laws and regulations may make our products, services, and solutions unnecessary or less economically beneficial to our customers, adversely affecting demand for our products, services, and solutions.
Certain of our products, services and solutions assist various industries and municipalities in meeting stringent environmental and safety requirements enacted for the purpose of making water cleaner and safer. Our future growth is dependent in part on the impact and timing of potential new water laws and regulations, as well as potential changes to existing laws and regulations. If stricter laws or regulations are delayed or are not enacted, or repealed or amended to be less strict, or enacted with prolonged phase‑in periods, or not enforced, demand for our products and services may be reduced. We are currently unable to predict whether changes to statutes and rules will affect demand for our products and services. To the extent that such changes have a negative impact on us, including as a result of related uncertainty, these changes may materially and adversely impact our business, financial condition, results of operations or prospects.
If we become subject to claims relating to handling, storage, release, or disposal of hazardous materials, we could incur significant costs and experience delays in our business due to our efforts to comply.
Our business activities, including our manufacturing processes and waste recycling and treatment processes, currently involve the use, treatment, storage, transfer, handling and/or disposal of hazardous materials, chemicals, and wastes. These activities create a risk of significant environmental liabilities and reputational damage. Under applicable environmental laws and regulations, including RCRA and CERCLA, we could be strictly, jointly, and severally liable for releases of regulated substances by us at our current or former properties or the properties of others or by other businesses that previously owned or used our current or former properties. We could also be liable or incur reputational damage if we merely generate hazardous materials or wastes, or arrange for their transportation, disposal, or treatment, or we transport such materials, and they are subsequently released or cause harm. Our business activities also create a risk of contamination or injury to our employees, customers or third parties, from the use, treatment, storage, transfer, handling and/or disposal of these materials, and these activities could result in accidental contamination or injury to the general public, as end‑users of our industrial and municipal customers’ products and services.
In the event that our business activities result in environmental liabilities, such as those described above, we could incur significant costs or reputational damage in connection with the investigation and remediation of environmental contamination, and we could be liable for any resulting damages including natural resource damages. Such liabilities could exceed our available liquidity or any applicable insurance coverage we may have. Additionally, we are subject to, on an ongoing basis, federal, state, and local laws and regulations governing the use, storage, handling and disposal of these materials and specified waste products. The cost of compliance with these laws and regulations may become significant and could have a material adverse effect on our business, financial condition, results of operations or prospects.
Failure to retain our existing senior management, skilled technical, engineering, sales and other key personnel or the inability to attract and retain new qualified personnel could materially and adversely impact our ability to operate or grow our business.
Our success depends to a significant extent on our ability to attract and retain talent, specifically in senior management and skilled technical, engineering, sales, project management and other key roles. Macroeconomic conditions, specifically labor shortages, increased competition for employees and wage inflation, could have a material impact on our ability to attract and retain talent, our turnover rate, and the cost of operating our business. If we are unable to attract and retain sufficient talent, minimize employee turnover, or manage wage inflation, it could have a material adverse effect on our business, financial condition, results of operations or prospects.

Wastewater operations may result in contamination or pose other significant risks that could cause us to incur significant costs.
Wastewater treatment involves various unique risks. If our treatment systems fail or do not operate properly, or if there is a spill, untreated or partially treated wastewater could discharge onto property or into nearby streams and rivers, causing various damages and injuries, including environmental damage. These risks are most acute during periods of substantial
18


rainfall or flooding, which are the main causes of sewer overflow and system failure. Liabilities resulting from such damages and injuries could materially adversely affect our business, financial condition, results of operations or prospects.
Weather conditions, climate change, and legislation or regulations addressing climate change may adversely impact our business, financial condition, results of operations and prospects.
The physical impacts of climate change are highly uncertain and vary depending on geographical location, but could include changing temperatures, droughts, water shortages, wildfires, changes in weather and rainfall patterns, changes in sea levels, and changing storm patterns and intensities. These impacts present several potential challenges to water and wastewater service providers, such as potential degradation of water quality and changes in demand for water services, particularly during periods of increased precipitation, flooding, or water shortages. Inclement weather and extreme weather events may have varying impacts on our business.Certain events may disrupt the operations of our customers, creating customer shutdowns that prevent or defer our performance of services or sale of equipment, while other events may drive increased demand for our products and services, particularly emergency response services, which may create volatility in our financial results. Additionally, these events may disrupt our own operations and the operations of our suppliers, including the operation of manufacturing plants, the transportation of raw materials from our suppliers, and the transportation of products to our customers, any of which may increase our costs, reduce our productivity and adversely affect our business, financial condition, results of operations and prospects.

Additionally, concern over climate change may result in new or increased legal and regulatory requirements to reduce or mitigate the effects of climate change, including limitations on greenhouse gas emissions, which could increase our costs or require additional investments in our facilities and equipment. New legislation and regulatory requirements may also impact our customers and suppliers, which could affect demand for our products or our ability to source key materials. In addition, our customers and suppliers may impose their own requirements with respect to climate change and greenhouse gas emissions. Any failure to comply with those requirements may also affect demand for our products or our ability to source key materials. Any failure to achieve our own goals with respect to reducing our impact on the environment, or any perception of a failure to act responsibly with respect to the environment or to effectively respond to regulatory requirements concerning climate change, can lead to adverse publicity, resulting in an adverse effect on our business or damage to our reputation.

Our business may be materially adversely affected by risks associated with international sales and operations.
Our international sales and operations are subject, in varying degrees, to risks inherent to doing business outside the U.S. These risks include tariffs and other trade restrictions, import and export requirements, foreign taxation policies, limitations on our ability to repatriate funds, unanticipated regulatory changes, geopolitical risks, political instability, currency fluctuations, varying levels of protection of intellectual property, difficulty enforcing agreements, disruptions in global supply chains, labor disruptions, and potential violations of anti-corruption laws.

In addition to the general risks that we face outside the U.S., our operations in emerging markets could involve additional uncertainties for us, including risks that an outbreak or escalation of any insurrection or armed conflict may occur; governments may seek to nationalize our assets; or governments may impose or increase investment barriers or other restrictions affecting our business.
We currently have operations and source and manufacture certain of our materials and products for global distribution from third‑party suppliers and manufacturers in the People’s Republic of China. Operating in China exposes us to political, legal, and economic risks. Our ability to operate in China may be adversely affected by changes in U.S. and Chinese relations, laws and regulations, such as those related to, among other things, taxation, import and export tariffs, environmental regulations, energy use, land use rights, intellectual property, currency controls, network security, employee benefits and other matters, and we may not obtain or retain the requisite legal permits to continue to operate in China, or we may become subject to costs or operational limitations imposed in connection with obtaining and complying with such permits. We may also experience difficulty in managing relations with our employees, distributors, suppliers, or customers, with whom disagreements or conflicts of interest could materially adversely affect our operations or our ability to source and manufacture certain of our materials and products in China.
19


If we do not adequately protect our intellectual property, or if third parties infringe our intellectual property rights or claim that we are infringing their intellectual property rights, we may suffer competitive injury, expend significant resources enforcing our rights or defending against such claims, or be prevented from selling products or services.
We own numerous patents, trademarks, service marks, copyrights, trade secrets and other intellectual property and hold licenses to intellectual property owned by others, which in aggregate are important to our business. The intellectual property rights that we have and may obtain, however, may not provide our products and services with a significant competitive advantage because our rights may not be sufficiently broad or may be challenged or invalidated. Our failure to obtain or maintain intellectual property rights that convey competitive advantage, adequately protect our intellectual property, or detect or prevent circumvention or unauthorized use of such property and the cost of enforcing our intellectual property rights could materially adversely impact our business, financial condition, results of operations or prospects. Any dispute or litigation regarding intellectual property could be costly and time consuming due to the complexity and the uncertainty of intellectual property litigation. Our intellectual property portfolio may not be useful in asserting a counterclaim, or negotiating a license, in response to a claim of infringement or misappropriation. We may incur significant costs and diversion of management attention and resources as a result of such claims of infringement or misappropriation, and we or our suppliers or subcontractors could lose rights to critical technology, be unable to license critical technology, provide or sell critical products or services, or be required to pay substantial damages or license fees with respect to the infringed rights or be required to redesign, rework, reprogram, or replace our or our customers’ products, subcomponents, software, or systems, or recast our valuable brands at substantial cost, any of which could materially adversely impact our competitive position, financial condition and results of operations even if we successfully defend against such claims of infringement or misappropriation.
Our industry is highly fragmented and localized.
We operate in markets that are characterized by customer demand that is often broad in scope but localized in delivery. We compete with companies that may be better positioned to capitalize on highly localized relationships and knowledge that are difficult for us to replicate. Our potential customers may prefer local suppliers, in some cases because of existing relationships and in other cases because of local legal restrictions or incentives that favor local businesses. Smaller regional suppliers may also have lower cost structures. As a result, efforts to expand or support our service network may not improve our ability to penetrate new local markets or expand our footprint in existing markets.
Our contracts with federal, state, and local governments involve unique risks and may be terminated or adversely modified prior to completion, which could adversely affect our business.
We derive, and expect to continue to derive in the future, a portion of our revenue from government customers, including municipalities. Sales to governments and related entities present unique risks, including potential disruption due to appropriation and spending patterns, delays in the adoption of new technologies due to political, fiscal or bureaucratic processes, delays in approving budgets, long purchase and payment cycles, competitive bidding requirements, qualification requirements, extensive specification development and price negotiations, milestone requirements and the potential unenforceability of limitations on liability or other contractual provisions. Government contracts may contain provisions not typically found in commercial contracts, including provisions permitting the government to terminate for convenience, reduce scope and potential future revenue, modify certain terms and conditions of existing contracts, suspend performance, impose fines or penalties, subject us to criminal prosecution or debarment, subject awarded contracts to protests or challenges by competitors, or claim rights in technologies developed by us.Exercise of any of these rights could cause us to recognize lower revenue or margin than anticipated under our government contracts.Additionally, because our water treatment systemsprojects and technologies,solutions for municipal customers often include fixed‑price contracts with milestone billings and liquidated damages for our delay, our performance under such contracts involves risks such as not receiving payments, not receiving payments in a timely manner or incurring significant damages if certain milestones are not met or not met on schedule. As a result, we could experience a material adverse effect on our business, financial condition, results of operations or prospects.

We rely, in part, on third‑party sales representatives to assist in selling our products, services and solutions, and the failure of these representatives to perform as expected could reduce our future sales.

20


Sales of our products, services, and solutions to some of our customers are accomplished, in part, through the efforts of third‑party sales representatives. We are unable to predict the extent to which these third‑party sales representatives will be successful in marketing and selling our products. Moreover, many of these third‑party sales representatives also market and sell competing products and may more aggressively pursue sales of our competitors’ products. Our third‑party sales representatives may terminate their relationships with us at any time on short or no notice. Our future performance may also depend, in part, on our ability to attract, incentivize and retain additional third‑party sales representatives that will be able to market and support our products effectively, especially in markets in which we have not previously sold our products. If we cannot retain our current third‑party sales representatives or recruit additional or replacement third‑party sales representatives or if these sales representatives are not effective, it could have a material adverse effect on our business, financial condition, results of operations or prospects.

Product defects and unanticipated or improper use of our products could adversely affect our business, reputation, and financial statements.

Manufacturing or design defects in our products or unanticipated or improper use of our products by our customers could create product safety, regulatory or other risks, including personal injury, death, or property damage. These events could lead to recalls or safety alerts relating to our products, result in the removal of a product from the market or result in product liability claims being brought against us. Recalls, removals, and product liability claims can result in significant costs, as well as mobilenegative publicity and damage to our reputation that could reduce demand for our products and have a material adverse effect on our business, financial condition, results of operations or prospects.

Further, it is generally our responsibility to service the equipment we provide our customers throughout the duration of our contract with such customers, and our customers may be required to maintain insurance covering loss, damage or injury caused by our equipment. However, we are not able to monitor our customers’ use or maintenance of their water systems or their compliance with our contracts or usage instructions. Customers’ failure to properly use, maintain or safeguard their equipment or customers’ noncompliance with insurance requirements may reflect poorly on us as the provider of such equipment and, as a result, damage our reputation.

Our operations are subject to various hazards that may cause personal injury or property damage and increase our operating costs, and which may exceed the coverage of our insurance or for which we are not insured.
There are inherent risks to our operations. We are exposed to risks posed by severe weather and other natural disasters, such as hurricanes and earthquakes. In addition to natural risks, hazards (such as fire, explosion, collapse, or machinery failure) are inherent risks in our operations which may occur as a result of inadequate internal processes, technological flaws, human error, or certain events beyond our control. We also utilize approximately 840 vehicles in connection with our offsite services and distribution operations and, from time to time, these drivers are involved in accidents which may cause injuries, spills, or uncontrolled discharges and in which goods carried by these drivers may be lost or damaged. The hazards described above can cause significant personal injury or loss of life, severe damage to or destruction of property, plants, and equipment, including customer or third‑party property, contamination of, or damage to, the environment and suspension of operations. The occurrence of any of these events may subject us to investigations, require us to perform remediation, or result in us being named as a defendant in lawsuits asserting claims for substantial damages, environmental cleanup costs, personal injury, natural resource damages and fines or penalties. As a result, we may from time to time become exposed to significant liabilities for which we may not have adequate insurance coverage. We may also become exposed to certain claims that are excluded from our insurance coverage, such as claims of fraud or for punitive damages. Although we have liability insurance, we cannot be certain that this insurance coverage will continue to be available to us at a reasonable cost or will be adequate to cover any product liability claims. In addition, such events may affect the availability of personnel, proper functioning of our information technology infrastructure and availability of third parties on whom we rely, any of which consequences could have a material adverse effect on our business, financial condition, results of operations or prospects.
21


Financial and Credit-Related Risks
Our financial results may fluctuate from period to period and can be difficult to predict.
Our financial results may be impacted by large projects, which often have lower margins and greater risk from both a timing and execution standpoint than standard product sales. The timing of these project awards is often unpredictable and outside of our control. If we fail to accurately estimate our operating costs to complete these projects or if we fail to execute these projects efficiently and timely, our margins on these projects could be further eroded. The timing of these project awards is often unpredictable and can change based upon customer requirements due to a number of factors affecting the project that are outside of our control, such as funding, readiness of the project and regulatory approvals. If any of these large projects get delayed or canceled, our results during the periods in which these projects were scheduled to occur could be adversely affected and the delay or failure could have a material adverse effect on our business, financial condition, results of operations or prospects. In addition, our contracts for large capital water treatment projects, systems and solutions for municipal and industrial applications are generally fixed‑price contracts with milestone billings. Additionally, competitive‑bid processes impose significant uncertainty with respect to our prospects for success, and our failure to properly predict our win rate could reduce our margins. Accordingly, our financial results for any given period may fluctuate and can be difficult to predict.
Our substantial indebtedness could adversely affect our financial condition and limit our ability to raise additional capital to fund our operations.
We have a significant amount of indebtedness. As of September 30, 2021, we had total indebtedness of $754.9 million, including $473.8 million of borrowings under our term loan facility, $37.3 million borrowings under our revolving credit facility, $150.1 million of borrowings related to our Securitization facility which includes $0.1 million of accrued interest, $93.4 million in borrowings related to equipment financings, and $0.4 million of notes payable related to certain equipment related contracts. We also had $10.1 million of letters of credit issued under our $350.0 million revolving credit facility. We cannot provide any assurance that our business will generate sufficient cash flow from operations in amounts sufficient to enable us to fund our debt service obligations and other liquidity needs.Our inability to generate sufficient cash flow to satisfy our debt obligations could materially adversely affect our business, financial condition, results of operations, or prospects.

Our high level of indebtedness could, among other things, limit our ability to obtain additional financing in the future, reduce the amount of cash available for working capital, capital expenditures and other business needs, increase our vulnerability to adverse changes in the economy, expose us to greater interest rate risk, restrict us from making strategic acquisitions, force us to make non-strategic divestitures, place us at a disadvantage compared to less leveraged competitors, and increase our costs of borrowing. Any one of these impacts could have a material effect on our business, financial condition, results of operations, prospects, and our ability to satisfy our obligations in respect of our outstanding debt.

Our variable rate indebtedness subjects us to interest rate risk, which could cause our debt service obligations to increase significantly.
Borrowings under our senior secured credit facilities are at variable rates of interest and expose us to interest rate risk. Interest rates are still near historically low levels and are projected to rise in the future. If interest rates rise, our debt service obligations on the variable rate indebtedness will increase even though the amount borrowed may remain the same, and our net income and cash flows will correspondingly decrease. Assuming no prepayments of the term loan facility (which had $473.8 million outstanding as of September 30, 2021) and that our revolving credit facility was fully drawn, each 0.125% change in interest rates would result in an approximate change of $1.0 million in annual interest expense on the indebtedness under our senior secured credit facilities. We entered into an interest rate swap during the third quarter of fiscal 2020 to mitigate risks associated with variable rate debt. The interest rate swap became effective June 30, 2020, has a term of five years to hedge the variability of interest payments on the first $500.0 million of the Company’s senior secured debt and provides for a fixed rate of 0.61%.

The covenants in our senior secured credit facilities impose restrictions that may limit our operating and financial flexibility.
Our senior secured credit facilities contain a number of significant restrictions and covenants that limit our ability, among other things, to incur additional indebtedness, pay dividends on or repurchase our outstanding capital stock, prepay certain indebtedness, create certain liens, divest certain assets, make certain investments, and enter into new lines of business.

In addition, our senior secured credit facilities contain a financial covenant requiring us to comply with a 5.55 to 1.00 first lien net leverage ratio test. This financial covenant is solely for the benefit of the lenders under our revolving credit facility and is tested as of the last day of a quarter on which the aggregate amount of revolving loans and letters of credit outstanding under the revolving credit facility (net of cash collateralized letters of credit and undrawn outstanding letters of credit in an amount of up to 50% of the revolving credit facility) exceeds 12.5% of the total commitments thereunder.
These covenants could materially adversely affect our ability to finance our future operations or capital needs. Furthermore, they may restrict our ability to expand and pursue our business strategies and otherwise conduct our business. Our ability to comply with these covenants may be affected by circumstances and events beyond our control, such as prevailing economic conditions and changes in regulations, and we cannot provide any assurance that we will be able to comply with such covenants. These restrictions also limit our ability to obtain future financings to withstand a future downturn in our business or the economy in general. In addition, complying with these covenants may also cause us to take actions that may make it more difficult for us to successfully execute our business strategy and compete against companies that are not subject to such restrictions.
A breach of any covenant in our senior secured credit facilities or the agreements and indentures governing any other indebtedness that we may have outstanding from time to time would result in a default under that agreement or indenture after any applicable grace periods. A default, if not waived, could result in acceleration of the debt outstanding under the agreement and in a default with respect to, and an acceleration of, the debt outstanding under other debt agreements. If that occurs, we may not be able to make all of the required payments or borrow sufficient funds to refinance such debt. Even if new financing were available at that time, it may not be on terms that are acceptable to us or terms as favorable as our current agreements. If our debt is in default for any reason, our business, results of operations and financial condition could be materially and adversely affected.
Seasonality of sales and weather conditions may adversely affect, or cause volatility in, our financial results.
We experience seasonal demand in a number of our end markets, as demand for infrastructure and municipal products and projects generally follows warm weather trends. Seasonal effects may vary from year to year and are impacted by weather patterns, particularly by temperatures, heavy flooding, and droughts. Our operating results and financial condition could be materially and adversely affected by severe weather, natural disasters, or other environmental factors. Repercussions of these catastrophic events may include shutting down operations, a need to obtain additional equipment or supplies on an emergency basis, evacuation of or injury to personnel, damage to equipment or property, loss of productivity and harm to our reputation, any of which may result in a decrease in our revenue or decreased profitability.
We may incur impairment charges for our goodwill and other indefinite‑lived intangible assets which would negatively impact our operating results.
We have a significant amount of goodwill and purchased intangible assets on our balance sheet. As of September 30, 2021, the net carrying value of our goodwill and other indefinite‑lived intangible assets totaled approximately $441.6 million. The carrying value of goodwill represents the fair value of an acquired business in excess of identifiable assets and liabilities as of the acquisition date. The carrying value of indefinite‑lived intangible assets represents the federal hazardous waste treatment management permits obtained for locations operated by the Company. We do not amortize goodwill and indefinite‑lived intangible assets that we expect to contribute indefinitely to our cash flows, but instead we evaluate these assets for impairment at least annually, or more frequently if changes in circumstances indicate that a potential impairment could exist. Significant negative industry or economic trends, disruptions to our business, inability to effectively integrate acquired businesses, unexpected significant changes, or planned changes in use of the assets,
23


divestitures and market capitalization declines may impair our goodwill and other indefinite‑lived intangible assets. Any charges relating to such impairments could materially adversely affect our financial condition and results of operations.
Our ability to use our net operating loss carryforwards may be limited.

As of September 30, 2021, we had approximately $297.1 million of U.S. federal and state net operating loss carryforwards (“NOLs”). Our federal NOLs begin to expire in 2035, while certain state NOLs began to expire in 2019. Utilization of these NOLs depends on many factors, including our future income, which cannot be assured. We maintain a full valuation allowance against these NOLs.

We may be unable to bid on or enter into significant long‑term agreements if we are not able to obtain letters of credit, bank guarantees or surety bonds, and our liquidity may be adversely affected by bonding requirements.
A portion of our business, including our water supplytreatment projects and solutions, requires us to provide letters of credit, bank guarantees or surety bonds in support of our commitments and as part of the terms and conditions on water treatment projects. In addition, we are required to provide letters of credit or surety bonds to the department of environmental protection or equivalent in some states in order to maintain our licenses to handle hazardous waste at certain of our regeneration facilities. We have in the past been, and may in the future be, required to provide bid bonds or performance bonds to secure our performance on certain projects or, in some cases, as a pre‑requisite to submit a bid on a potential project. Our inability to obtain adequate bonding or letters of credit to meet bid requirements or enter into significant long‑term agreements could have a material adverse effect on our business, financial condition, results of operations or prospects.
Information Technology and Cybersecurity Risks
We are increasingly dependent on the continuous and reliable operation of our information technology systems, and a disruption of these systems could materially and adversely affect our business.
We rely on our information technology systems in connection with various aspects of the operation of our business, including customer relationship management, customer service, contract options through its segment branch network. Headquarteredpurchasing, inventory management, project management, human resource management, billing, and accounting. We also rely on digitally connected systems for monitoring and operation of certain of our water treatment installations. Many of our products, services and solutions depend on the integrity of our information technology systems, including our remote monitoring and data analytics features and our automated control solutions. These systems are inherently susceptible a number of threats, including, but not limited to, viruses, ransomware, malware, malicious codes, hacking, phishing, denial of service actions, human error, network failures, electronic loss of data, and other electronic security breaches. Although we have experienced attempts by external parties to access our networks and systems, these attempts have not resulted in Pittsburgh, Pennsylvania, EWTany material breaches, disruptions, or loss of information to date. A successful cyber-attack may result in the loss or compromise of customer, financial or operational data, theft of intellectual property, disruption of billing, collections or normal field service activities, disruption of data analytics and electronic monitoring and control of operational systems, loss of revenue, ransomware payments, remediation costs related to lost, stolen, or compromised data, repairs to infrastructure, physical systems or data processing systems, increased cybersecurity protection costs, or violation of U.S. and international privacy laws, which may result in litigation. Any of these occurrences could harm our reputation or have a material adverse effect on our business, financial condition, results of operation and prospects.

We have adopted measures to mitigate potential risks associated with information technology disruptions and cybersecurity threats; however, there is no assurance that these measures will prevent cyber-attacks or security breaches. We also have a multi‑national corporationconcentration of operations on certain sites, such as production and shared services centers, where business interruptions could cause material damage and costs. Although we continue to assess these risks, implement controls and perform business continuity and disaster recovery planning, we cannot be sure that interruptions with material adverse effects will not occur.
Our Water One® services are provided using remote monitoring technology that is connected to the “Internet of Things” (IoT), which is inherently susceptible to cyber-attacks and outages. A successful attack may result in inappropriate access to our or our customers’ information or systems or cause our products to function improperly. We have experienced outages due to disruptions in service by cellular providers. Although these outages have not had a
24


material impact on our business to date, if outages occur with greater frequency or for extended durations, it could adversely affect our ability to monitor our assets, which could harm our reputation or result in a loss of revenue, failure to fulfill contractual obligations and additional costs to repair damages.
If we experience a significant data security breach or fail to detect and appropriately respond to a significant data security breach, our business and reputation could suffer.
The nature of our business involves the receipt and storage of information about our customers, suppliers, employees, operations and financial performance. Further, we rely on various information technology systems to capture, process, store, and report data in connection with the products, services, and solutions that we provide to our customers, such as our Water One® services. We have procedures in place to detect and respond to data security incidents. However, because the techniques used to obtain unauthorized access, disable, or degrade service, or sabotage systems change frequently and may be difficult to detect for long periods of time, we may be unable to anticipate these techniques or implement adequate preventive measures. In addition, hardware, software, or applications we develop or procure from third parties may contain defects in design or manufacture or other problems that could unexpectedly compromise information security. We outsource administration of certain functions to vendors that could be targets of cyber attacks. Any theft, loss and/or fraudulent use of customer, employee, or proprietary data as a result of a cyber attack targeting us or one of our third-party service providers could subject us to significant litigation, liability, and costs, as well as adversely impact our reputation with customers and regulators, among others. Unauthorized parties may also attempt to gain access to our systems or facilities and to our proprietary business information. If our efforts to protect the security of information about our customers, suppliers and employees are unsuccessful, a significant data security breach may result in costly government enforcement actions, private litigation and negative publicity resulting in reputation or brand damage with customers, and our business, financial condition, results of operations or prospects could suffer. While we maintain insurance coverage that is designed to address certain aspects of cyber risks, such insurance coverage may be insufficient to cover all losses or all types of claims that may arise in the event we experience a cybersecurity incident, data breach or disruption, unauthorized access, or failure of systems.
We are subject to laws, rules, and regulations in the United States (such as the California Consumer Protection Act (“U.S.”CCPA”)), and other countries relating to the collection, use and security of employee and other data. Our ability to execute transactions and to possess and use personal information and data in conducting our business subjects us to legislative and regulatory burdens that may require us to notify regulators and customers, employees, and other individuals of a data security breach, including in the European Union under the EU General Data Protection Regulation, or the GDPR. Evolving compliance and operational requirements under the GDPR, the CCPA, and the privacy laws of other jurisdictions in which we operate impose significant costs that are likely to increase over time.
Legal and Regulatory Risks
The cost of complying with complex governmental regulations applicable to our business, sanctions resulting from non‑compliance or reduced demand resulting from certain changes in regulations could increase our operating costs and reduce our profit.
Our operations are subject to various licensing, permitting, approval and reporting requirements imposed by federal, state, local and foreign laws. Our operations are subject to inspection and regulation by various governmental agencies, including the U.S. EPA, the Occupational Safety and Health Administration and equivalent state and local agencies, as well as their counterparts in various states and foreign countries. A major risk inherent in our operations is the need to obtain and renew permits from federal, state, and local authorities. Delays in obtaining permits, the failure to obtain a permit or a renewal permit for a project, challenges to our permits by local communities, citizen groups, landowners or others opposed to their issuance or the issuance of a permit with unreasonable conditions or costs could limit our ability to effectively provide our services. We are also required to secure and maintain licenses required by several states which can take a significant amount of time and result in our inability or delays in our ability to bid on and execute certain projects. If we fail to secure or maintain any such licenses or if states place burdensome restrictions or limitations on our ability to obtain or maintain such licenses, we may not be able to operate in such states and our business, financial condition, results of operations or prospects may be materially adversely affected as a result.
25


Our business may be further impacted by changes in federal, state, and local requirements that set forth air and wastewater discharge parameters, constrain water availability and set quality and treatment standards. Our failure or inability to comply with the stringent standards set forth by regulating entities or to provide cost‑effective and compliant design and construction solutions could result in fines or other penalties, and could have a material adverse effect on our business, financial condition, results of operations or prospects.
Foreign, federal, state, and local environmental, health and safety laws and regulations impose substantial compliance requirements on our operations. Our operating costs could be significantly increased in order to comply with new or stricter regulatory standards imposed by foreign, federal, and state environmental agencies.
Our operations, products and services are governed by various foreign, federal, state and local environmental protection and health and safety laws and regulations, including, without limitation, the federal Safe Drinking Water Act, the Clean Water Act, the Clean Air Act, the Resource Conservation and Recovery Act, the Occupational Safety and Health Act, the Toxic Substances Control Act and the Federal Insecticide, Fungicide, and Rodenticide Act in the U.S., the Registration, Evaluation and Authorization of Chemicals, or REACH, directive in Europe, and similar foreign, federal, state and local laws and regulations and permits issued under these laws by the foreign, federal, state and local environmental and health and safety regulatory agencies. These laws and regulations establish, among other things, criteria and standards for drinking water and for discharges into the waters of the U.S. and its states, for the proper management of hazardous and non‑hazardous solid waste and for protection of public and worker health and safety. Pursuant to these laws, we are required to obtain various environmental permits from environmental regulatory agencies for our operations. We cannot provide any assurance that our operations, products, or services will be at all times in total compliance with these laws, regulations and permits or that we will be able to obtain or renew all required permits. If we violate or fail to comply with these laws, regulations or permits, we could be fined or otherwise sanctioned by regulators and be subject to lawsuits, civil or criminal, seeking enforcement and/or injunctive relief. We may also be subject to civil claims by citizens groups seeking to enforce environmental laws. In the event of an accident or if we otherwise fail to comply with applicable regulations, we could lose our permits or approvals and/or be held liable for damages and monetary penalties.
Environmental laws and regulations are complex and change frequently. These laws, and the enforcement thereof, have tended to become more stringent over time. It is possible that new standards could be imposed, either stricter or more lenient, that could result in the obsolescence of our products or lead to an interruption or suspension of our operations and have a material adverse effect on the productivity and profitability of a particular manufacturing facility, service, or product or on us as a whole.
Failure to comply with applicable anti‑corruption and trade laws, regulations, and policies, including the U.S. Foreign Corrupt Practices Act, could result in fines and criminal penalties, causing a material adverse effect on our business, financial condition, results of operations or prospects.
Due to our global operations, we are subject to regulation under a wide variety of U.S. federal and state and non‑U.S. laws, regulations and policies related to anti‑corruption and trade, including those related to export and import compliance, anti‑trust and money laundering. The U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act of 2010 and similar anti‑bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to government officials or other persons for the purpose of obtaining or retaining business. We operate in parts of the world that are recognized as high-risk regions for corruption. Our operations in these regions include sales to government and non-government customers and may include the use of third-party intermediaries. In certain circumstances, strict compliance with anti-bribery and trade laws, regulations and policies may conflict with local customs and practices in these regions.
The International Traffic in Arms Regulations generally require export licenses from the U.S. Department of State for goods, technical data and services sent outside the U.S. that have military or strategic applications. The Export Administration Regulations regulate the export of certain “dual use” goods, software, and technologies, and in some cases require export licenses from the U.S. Department of Commerce. Office of Foreign Asset Control regulations implement various sanctions programs that include prohibitions of restrictions on dealings with certain sanctioned countries, governments, entities, and individuals. Our policies mandate compliance with these trade laws, regulations, and policies, and we have established procedures designed to assist us and our personnel in compliance with applicable
26


U.S. and international laws and regulations. However, we cannot provide any assurance that our internal control policies and procedures will always protect us from improper conduct of our employees or business partners.
In the event that we believe or have reason to believe that our employees or agents have or may have violated applicable laws, including anti‑corruption and trade laws, regulations, and policies, we may be required to investigate or engage outside counsel to investigate the relevant facts and circumstances, which can be expensive and require significant time and attention from senior management. Any such violation could result in substantial fines, sanctions, civil and/or criminal penalties, imprisonment, disgorgement of profits, debarment from government contracts and curtailment of operations in certain jurisdictions, and might materially adversely affect our business, financial condition, results of operations or prospects. In addition, actual or alleged violations could damage our reputation and diminish our ability to do business. Furthermore, detecting, investigating, and resolving actual or alleged violations is expensive and can consume significant time and attention of our senior management.

Item 1B. Unresolved Staff Comments
None.
Item 2. Properties
As of September 30, 2021, we operated 156 locations located in the United States, Canada, the United Kingdom, (“UK”), the Netherlands, Germany, Australia, China, Singapore, India, and Korea, including 11 manufacturing facilities, 7 research and India.development facilities, and 91 service branches. We own 20 of these properties and lease the remaining 136 properties. The manufacturing and research and development facilities support both our ISS and APT segments globally.  The service branches primarily support our ISS segment.  Our North American presence includes 11 resin regeneration plants, 3 carbon reactivation plants, and 1 wastewater ion exchange facility.
Item 3. Legal Proceedings
From time to time, we are subject to various claims, charges and litigation matters that arise in the ordinary course of business. We believe these actions are a normal incident of the nature and kind of business in which we are engaged. While it is not feasible to predict the outcome of these matters with certainty, we do not believe that any asserted or unasserted legal claims or proceedings, individually or in the aggregate, will have a material adverse effect on our business, financial condition, results of operations or prospects.

In November 2018, a purported shareholder of the Company filed a class action lawsuit, captioned McWilliams v. Evoqua Water Technologies Corp., Case No. 1:18-CV-10320, in the United States District Court for the Southern District of New York alleging that the Company and senior management violated federal securities laws by issuing false, misleading, and/or omissive disclosures in the period leading up to the Company’s October 30, 2018 announcement of, among other things, (a) preliminary results for the full-year fiscal 2018 that were below previous expectations and (b) a transition from a three-segment structure to a two-segment operating model. In January 2019, the court appointed lead plaintiffs and lead counsel and re-captioned the action as In re Evoqua Water Technologies Corp. Securities Litigation (the “Securities Litigation”). In March 2019, lead plaintiffs filed an amended complaint, which asserted claims pursuant to the Exchange Act and the Securities Act against the Company, members of the Company’s board of directors, senior management, a former executive, AEA Investors LP (“AEA”), and the underwriters of the Company’s IPO and secondary public offering. The amended complaint alleged that the defendants violated federal securities laws by issuing false, misleading, and/or omissive disclosures concerning the Company’s integration of acquired companies, the Company’s reduction-in-force, and the Company’s financial results of operations. The lawsuit sought compensatory damages in an unspecified amount and an award of costs and expenses to the plaintiff and class counsel. In March 2020, the Court granted the defendants’ motion to dismiss a portion of the claims, dismissing all claims predicated on supposedly intentional misstatements or omissions, which were brought under the Exchange Act. The claims that remained were those brought under the Securities Act. The Company filed an answer denying the material allegations of the complaint, the parties engaged in discovery, and lead plaintiffs filed a motion for class certification in December 2020.

27


On June 1, 2021, following mediation, the parties filed a stipulation agreeing to settle the Securities Litigation, subject to Court approval, for $16.65 million, all of which was paid by insurance. On November 1, 2021, the Court granted final approval of the settlement and entered a judgment dismissing the Securities Litigation.

In April 2019, another purported shareholder of the Company filed a derivative lawsuit in the United States District Court for the Western District of Pennsylvania, captioned Dallas Torgersen v. Ronald C. Keating, Case No. 2:19-CV-410. The complaint names as defendants the Company’s Chief Executive Officer and Chief Financial Officer, as well as members of the Company’s board of directors, and it names the Company as a nominal defendant. The complaint alleges, among other things, that the individual defendants violated federal securities laws by issuing false, misleading, and/or omissive disclosures in the period leading up to the Company’s October 30, 2018 disclosures, and that they breached their fiduciary duties to the Company. The lawsuit seeks compensatory damages in an unspecified amount, an award of costs and expenses, restitution from the individual defendants, and an order directing the Company and the individual defendants to take unspecified actions to reform and improve the Company’s corporate governance and internal procedures.

In July 2020, a different purported shareholder of the Company filed a second shareholder derivative lawsuit ostensibly on behalf of the Company in the same court, captioned Robert Hyams v. Ronald C. Keating, Case No. 2:20-CV-1112. The complaint is similar to the one in Torgersen but also names as defendants AEA and a number of its affiliated entities. In September 2020, the court consolidated the Torgersen and Hyams cases under the caption In re Evoqua Water Technologies Corp. Derivative Litigation (the “Derivative Litigation”). The Derivative Litigation was stayed in June 2019 pending resolution of the Securities Litigation.

In February 2020, yet another purported shareholder of the Company sent a letter to the board of directors demanding that it investigate and bring claims against various directors and officers for the same matters that were already the subject of the Securities Litigation and the Derivative Litigation. Although no lawsuit was filed by this purported shareholder, the shareholder agreed to stay matters on terms similar to what was agreed in the Derivative Litigation.

On July 28, 2021, following mediation, the parties signed an agreement, subject to Court approval, to settle the Derivative Litigation and the stockholder demand for non-cash consideration, including certain enhancements to corporate governance practices and internal procedures. On November 2, 2021, the Court granted final approval of the settlement and entered a judgment dismissing the Derivative Litigation.

In October 2020, the Company learned that the SEC and the United States Attorney’s Office for the District of Massachusetts are investigating whether financial misstatements were made in the Company’s public filings and earnings announcements prior to October 2018, similar to what is alleged in the Securities Litigation. The Company is organizationally structuredcooperating with those investigations. Although the Company is unable to predict the outcome or reasonably estimate any potential loss, we currently believe that this matter will not have a material adverse effect on our business, financial condition, results of operations or prospects.

Item 5.    Market for Registrant’s Common Equity, Related Stockholder Matters, and Issuer Purchases of Equity Securities
Market Information
The Company’s common stock is traded on the New York Stock Exchange under the symbol “AQUA.”
As of October 31, 2021, there were 40 holders of record of the Company’s common stock, which does not reflect individual holders of shares held beneficially or shares held in “street” name. Accordingly, the number of beneficial owners of our common stock exceeds this number.
Dividend Policy
No dividends were paid to shareholders during the fiscal years ended September 30, 2021, 2020 or 2019. The Company currently intends to retain all of its future earnings, if any, to finance operations, development and growth of its business and repay indebtedness. Most of the Company’s indebtedness contains restrictions on the Company’s activities, including paying dividends on its capital stock. See Note 12, “Debt” in Part II, Item 8 of this Annual Report on Form 10-K. Any future determination relating to our dividend policy will be made at the discretion of the Company’s board of directors and will depend on a number of factors, including future earnings, capital requirements, financial and market conditions, future prospects, contractual restrictions and covenants and other factors that the board of directors may deem relevant.

Stock Performance Graph
The following graph shows a comparison of cumulative total return to holders of shares of Evoqua’s common stock against the cumulative total return of the S&P Mid Cap 400 Index and the S&P Mid Cap 400 / Utility Index, which the Company selected as comparator indices for fiscal 2021, as well the S&P Small Cap 600 Index and the S&P Small Cap 600 / Utilities Index, which the Company used as comparator indices for fiscal 2020, from market close on November 2, 2017 (the first day of trading of our common stock) through September 30, 2021. The Company changed its comparator indices for fiscal 2021 to select indices that include companies whose equity securities are of comparable market capitalization, given the increase in the Company’s market capitalization as compared to fiscal 2020. The comparison of the cumulative total returns for each investment assumes that $100 was invested in Evoqua common stock and the respective indices on November 2, 2017 through September 30, 2021, including reinvestment of any dividends (although no dividends have been declared on our common stock to date). Historical share price performance should not be relied upon as an indication of future share price performance, and we do not make or endorse any predications as to future shareholder returns.
This performance graph and related information shall not be deemed “soliciting material” or be deemed “filed” for purposes of Section 18 of the Exchange Act or otherwise subject to the liabilities under that section, and shall not be deemed to be incorporated by reference into any future filing under the Securities Act or Exchange Act, except to the extent that we specifically incorporate it by reference into such filing.

Item 7. Management’s Discussion and Analysis ofFinancial Condition and Results of Operations
The following discussion and analysis of our financial condition and results of our operations should be read in conjunction with Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from such forward-looking statements. Factors that could cause or contribute to those differences include, but are not limited to, those identified below and those discussed in the section titled “Cautionary Note Regarding Forward-Looking Statements” and in Part I, Item 1A, “Risk Factors” in this Annual Report. Unless otherwise indicated or the context otherwise requires, all references to the “Company,” “Evoqua,” “Evoqua Water Technologies Corp.,” “we,” “us,” “our,” and similar terms refer to Evoqua Water Technologies Corp., together with its consolidated subsidiaries. Unless otherwise specified, all dollar amounts in this section are referred to in millions. Our fiscal year ends on September 30 of each year and references in this section to a year refer to our fiscal year. As such, references to: 2021 relates to the fiscal year ended September 30, 2021, 2020 relates to the fiscal year ended September 30, 2020, and 2019 relates to the fiscal year ended September 30, 2019.
Overview and Background
We are a leading provider of mission-critical water and wastewater treatment solutions, offering a broad portfolio of products, services, and expertise to support customers across various end markets. We are headquartered in Pittsburgh, Pennsylvania, with locations across 10 countries. We have a comprehensive portfolio of differentiated, proprietary technologies offered under market‑leading and well‑established brands. Our core technologies are primarily focused on removing impurities from water, rather than neutralizing them through the addition of chemicals.
Our solutions are designed to provide our customers with the quantity and quality of water necessary to meet their unique specifications. We enable our customers to achieve lower costs through greater uptime, throughput and efficiency in their operations while supporting their regulatory compliance and environmental sustainability requirements. We deliver and maintain these mission critical solutions through our extensive North American service network, assuring our customers continuous uptime with 91 service branches as of September 30, 2021. We have certified Evoqua Service Technicians within approximately a two-hour drive from more than 90% of our industrial North American customers’ sites. In addition, we sell our products and technologies internationally through direct and indirect sales channels. We have worked to protect water, the environment, and our employees for more than 100 years. As a result, we have earned a reputation for quality, safety, and reliability around the world. Our employees are united by a common purpose: Transforming water. Enriching life.®
Our vision “to be the world’s first choice for water solutions” and our values of “integrity, customers, sustainable, and performance” foster a culture that is focused on establishing a workforce that is enabled, empowered and accountable, creating a highly dynamic work environment.
We serve our customers through the following two reportable operating segments for the purpose of making operational decisions and assessing financial performance: (i) segments:
Integrated Solutions and Services segment, which provides application-specific solutions and full lifecycle services for critical water and wastewater applications across numerous end markets, including outsourced water service contracts, capital systems and related recurring aftermarket services, parts and consumables, and emergency services to enable recycle and reuse, improve operational reliability and performance, and promote environmental compliance; and

Applied Product Technologies segment, which provides highly differentiated and scalable water and wastewater products and technologies as stand-alone offerings or components in integrated solutions to a diverse set of system integrators and end-users globally.
32


Our segments draw from the same reservoir of leading technologies, shared manufacturing infrastructure, common business processes, and corporate philosophies. The key factors used to identify these reportable operating segments are the organization and alignment of our internal operations, the nature of the products and services and customer type.

Recent Developments, Key Factors, and Trends Affecting Our Business and Financial Statements
The following recent developments have affected our business and operating results during the year ended September 30, 2021:
Impact of the COVID-19 pandemic. Our business has been considered essential under federal and local standards, and we have maintained business continuity at our critical service branches and manufacturing facilities to date. We have taken measures throughout the duration of the pandemic to protect our employees, including implementation of remote working practices where possible and enhanced safety procedures for employees on site at our facilities and our customers’ facilities. These measures have resulted in additional incremental costs and reductions in service productivity over the course of the pandemic, although neither had a material adverse effect on our results of operations for fiscal 2021.
To date, the pandemic has negatively impacted sales volume across our business, due primarily to customer site access restrictions, temporary customer site closures, and temporary delays in annual maintenance activities by customers in certain end markets, although we started to see sales volume rebound in certain end markets during the second half of fiscal 2021, as further discussed below in the discussion of our results of operations. The implementation of vaccine mandates in fiscal 2022 may further increase costs and delay our performance of services for our customers or our internal business operations due to customer site access restrictions and labor shortages. Additionally, in the second half of fiscal 2021 we experienced increases in certain discretionary costs that were the subject of cost reduction actions earlier in the pandemic, particularly employee travel expenses. We have continued to focus on collecting outstanding customer account balances, and, through September 30, 2021, we have not experienced any deterioration in collections from our customers. We continue to evaluate the impact of the pandemic on our business and the potential effects of recent spikes in COVID-19 cases in certain regions, as well as challenges created by the macroeconomic conditions associated with the reopening of global economies, including inflation and availability constraints, which are discussed in more detail below.
For more information regarding factors and events that may impact our business, results of operations and financial condition from the effects of the COVID-19 pandemic, see Part I, Item 1A. “Risk Factors-The COVID-19 pandemic has adversely affected, and may continue to adversely affect, our business, financial condition, results of operations and prospects.”
Inflation and material availability. Material, freight, and labor inflation resulted in increased costs in fiscal 2021, and we expect this trend will continue in fiscal 2022. Although we have offset a portion of these increased costs through price increases and operational efficiencies to date, there can be no assurance that we will be able to continue to do so. If we are unable to manage commodity fluctuations through pricing actions, cost savings projects and sourcing decisions as well as through consistent productivity improvements, it may adversely impact our gross profit and gross margin in future periods. Additionally, supply chain disruptions and labor shortages have restricted and could further restrict availability of certain commodities and materials, which may result in delays in our execution of projects in fiscal 2022 and negatively impact revenues. We have taken and continue to take strategic actions focused on mitigating the impact of these challenges. Although these factors did not have a material adverse effect on our results of operations for fiscal 2021, if sustained, they could have a material adverse effect on our results of operations going forward.
Acquisitions and divestitures. On April 1, 2021, we acquired the assets of Water Consulting Specialists, Inc. (“WCSI”) for $12.0 million cash paid at closing. In addition, we recorded a liability of $0.8 million at closing associated with an earn-out related to the WCSI acquisition, which was subsequently revalued to $0.2 million and is included in Accrued
33


expenses and other liabilities on the Consolidated Balance Sheets. During the year ended September 30, 2021, we received cash of $21 thousand from the seller as a result of net working capital adjustments. WCSI is a leader in the design, manufacturing, and service of industrial high-purity water treatment systems. The acquisition strengthens the Company’s portfolio of high-purity water treatment systems and provides the opportunity to further expand its digitally enabled solutions and services in key industrial markets. WCSI is a part of the Integrated Solutions and Services segment. During the year ended September 30, 2021, the Company incurred approximately $0.1 million in acquisition costs, which are included in General and administrative expense on the Consolidated Statements of Operations.
On March 1, 2021, we completed the divestiture of the Lange containment system, geomembrane, and geosynthetic liner product line (the “Lange Product Line”) for $0.9 million in cash at closing. The Lange Product Line was a part of the Integrated Solutions and Services segment. During the year ended September 30, 2021, the Company recognized a loss of $0.2 million on the divestiture.
On December 17, 2020, we acquired the industrial water business of Ultrapure & Industrial Services, LLC (“Ultrapure”) for $8.7 million cash paid at closing. On April 1, 2021, we paid an additional $0.3 million as a result of net working capital adjustments. Ultrapure, based out of Texas, provides customers across multiple end markets with a variety of water treatment products and services, including service deionization, reverse osmosis, UV, and ozonation. Ultrapure will strengthen the Company’s service capabilities in the Houston and Dallas markets and is a part of the Integrated Solutions and Services segment. During the year ended September 30, 2021, the Company incurred approximately $0.2 million in acquisition costs, which are included in General and administrative expense on the Consolidated Statements of Operations.
On September 3, 2020, the Company acquired the assets of privately held Aquapure Technologies of Cincinnati (“Aquapure”), a Hamilton, Ohio based water service and equipment company. Aquapure serves the commercial and light industrial markets and provides customers with a variety of water treatment products and services, including deionization, reverse osmosis, softeners, and filtration systems. Aquapure is part of the Integrated Solutions and Services segment.
On December 31, 2019, we completed the sale of the Memcor ® product line to DuPont de Nemours, Inc. (Memcor ® is a trademark of Rohm & Haas Electronic Materials Singapore Pte. Ltd.). The Company recognized a $57.7 million net pre-tax benefit on the sale of the Memcor product line, net of $8.3 million of discretionary compensation payments to employees in connection with the transaction and $2.1 million in transaction costs incurred in the year ended September 30, 2020.

On October 1, 2019, we acquired a 60% investment position in San Diego-based Frontier Water Systems, LLC (“Frontier”), which included an agreement to acquire the remaining 40% interest in Frontier on or prior to March 30, 2024. This agreement gave holders of the remaining 40% interest in Frontier (the “Minority Owners”) the right to sell to Evoqua up to approximately 10% of the outstanding equity in Frontier at a predetermined price, which right was exercisable by the Minority Owners between January 1, 2021 and February 28, 2021 (the “Option”). The Minority Owners exercised the Option, and on April 8, 2021, the Company completed the purchase of an additional 8% of the outstanding equity in Frontier for approximately $1.5 million. As a result, the Company’s ownership position in Frontier increased to 68%. During the year ended September 30, 2021, the Company recorded an increase in the fair value of the Purchase Right liability for $2.1 million, which was recorded to Interest expense on the Consolidated Statements of Operations. As of September 30, 2021, $8.3 million is included in Other non‑current liabilities related to the Purchase Right on the Consolidated Balance Sheets.
Debt refinancing.On April 1, 2021, we completed the refinancing of the term loan (the “2014 Term Loan”) outstanding under our First Lien Credit Agreement dated January 15, 2014 (as modified, amended or supplemented from time to time, the “2014 Credit Agreement”), among EWT Holdings III Corp. (“EWT III”), EWT Holdings II Corp. (“EWT II”), the lenders party thereto and Credit Suisse AG as administrative agent and collateral agent. On April 1, 2021, EWT III entered into a Credit Agreement (the “2021 Credit Agreement”) among EWT III, as borrower, EWT II, as parent guarantor, the lenders from time to time party thereto, JPMorgan Chase Bank, N.A., as administrative agent and collateral agent, and ING Capital, LLC, as sustainability coordinator, which provides for (i) a senior secured term loan facility relating to a term loan (the “2021 Term Loan”) in the amount of $475.0 million maturing on April 1, 2028, and
34


(ii) a multi-currency senior secured revolving credit facility in an aggregate principal amount not to exceed the U.S. dollar equivalent of $350.0 million (the “2021 Revolving Credit Facility”) maturing on April 1, 2026.
On April 1, 2021, Evoqua Finance LLC (“Evoqua Finance”) entered into an accounts receivable securitization program (the “Receivables Securitization Program”) consisting of, among other agreements, (i) a Receivables Financing Agreement (the “Receivables Financing Agreement”) among Evoqua Finance, as the borrower, the lenders from time to time party thereto (the “Receivables Financing Lenders”), PNC Bank, National Association (“PNC Bank”), as administrative agent, Evoqua Water Technologies LLC (“EWT LLC”), an indirect wholly-owned subsidiary of the Company, as initial servicer, and PNC Capital Markets LLC (“PNC Markets”), as structuring agent, pursuant to which the lenders have made available to Evoqua Finance a receivables finance facility (the “Securitization Facility”) in an amount up to $150.0 million maturing on April 1, 2024, and (ii) Applied Product Technologies.a Sale and Contribution Agreement (the “Sale Agreement”) among Evoqua Finance, as purchaser, EWT LLC, as initial servicer and as an originator, and Neptune Benson, Inc., an indirectly wholly-owned subsidiary of the Company, as an originator (together with EWT LLC, the “Originators”).

On April 1, 2021, we borrowed $475.0 million under the 2021 Term Loan, $105.0 million under the 2021 Revolving Credit Facility and $142.2 million under the Securitization Facility. The net proceeds of these facilities, together with cash on hand, were used to repay all outstanding indebtedness under our 2014 Credit Agreement, in an aggregate principal amount of approximately $814.5 million. The reduction in the outstanding principal amount of our term loan of approximately $340.0 million was funded by draws on the 2021 Revolving Credit Facility, the Securitization Facility and $100.0 million of cash on hand. In addition to extending the maturities of our term loan and previous revolving credit facility, the refinancing reduced our weighted average cash borrowing cost and improved liquidity. See “Liquidity and Capital Resources” below for additional information. On September 30, 2021, the Company had $473.8 million outstanding under the 2021 Term Loan, $37.3 million outstanding on the 2021 Revolving Credit Facility, and $150.1 million outstanding under the Securitization Facility, which includes $0.1 million of accrued interest.
How We Assess the Performance of Our Business
In assessing the performance of our business, we consider a variety of performance and financial measures. The key indicators of the financial condition and operating performance of our consolidated business are revenue, gross profit, gross margin, and net income (loss). Management utilizes these financial measures prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) when reviewing the Company’s performance and making financial, operational, and strategic decisions, and believes they are useful metrics for investors that help with performance comparability period over period. In addition, we consider certain non-GAAP financial measures such as adjusted EBITDA and organic revenue, as described more fully below. We evaluate our business segments’ operating results based on revenue, income from operations (“operating profit”) and adjusted EBITDA on a segment basis. We believe these financial measures are helpful in understanding and evaluating the segments’ core operating results and facilitates comparison of our performance on a consistent basis period over period.
Revenue and Organic Revenue
Our revenue is a function of sales volumes and selling prices. We report revenue by segment and by source which includes revenue from product sales (capital projects and aftermarket) and revenue from service. Revenue is used by management to evaluate the performance of our business. Organic revenue, which is a non-GAAP financial measure, is defined as revenue excluding the impact of foreign currency translation and inorganic revenue. Inorganic revenue represents the impact from acquisitions and divestitures during the first 12 months following the closing of the acquisition or divestiture. Divestitures include sales of insignificant portions of our business that did not meet the criteria for classification as a discontinued operation. We exclude the effect of foreign currency translation from organic sales because foreign currency translation is not under management’s control, is subject to volatility and can obscure underlying business trends. We exclude the effect of acquisitions and divestitures because they can obscure underlying business trends and make comparisons of long-term performance difficult between the Company and its peers due to the varying nature, size, and number of transactions from period to period. Management believes that reporting organic revenue provides useful information to investors by helping identify underlying growth trends in our core business and facilitating easier comparisons of our revenue performance with prior and future periods and to our peers. See “Non-GAAP Reconciliations” in this Item 7 for a reconciliation of organic revenue to revenue.

35


Adjusted EBITDA
Adjusted EBITDA, which is a non-GAAP financial measure, is one of the primary metrics used by management to evaluate the strength and financial performance of our core business. Adjusted EBITDA is defined as net income (loss) before interest expense, income tax benefit (expense) and depreciation and amortization, adjusted for the impact of certain other items, including restructuring and related business transformation costs, share-based compensation, transaction costs, and other gains, losses, and expenses that we believe do not directly reflect our underlying business operations. We present adjusted EBITDA because we believe it is frequently used by analysts, investors, and other interested parties to evaluate and compare operating performance and value companies within our industry. Further, we believe it is helpful in highlighting trends in our operating results and provides greater clarity and comparability period over period to management and our investors regarding the operational impact of long-term strategic decisions regarding capital structure, the tax jurisdictions in which we operate, and capital investments. In addition, adjusted EBITDA highlights true business performance by removing the impact of certain items that management believes do not directly reflect our underlying operations and provides investors with greater visibility into the ongoing drivers of our business performance.
Management uses adjusted EBITDA to supplement GAAP measures of performance as follows:
to assist investors and analysts in comparing our operating performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance;
in our management incentive compensation, which is based in part on components of adjusted EBITDA;
in certain calculations under our senior secured credit facilities, which use components of adjusted EBITDA;
to evaluate the effectiveness of our business strategies;
to make budgeting decisions; and
to compare our performance against that of other peer companies using similar measures.
In addition to the above, our chief operating decision maker uses adjusted EBITDA of each reportable operating segment to evaluate the operating performance of such segments. Adjusted EBITDA on a segment basis is defined as earnings before depreciation and amortization, adjusted for the impact of certain other items that have been reflected at the segment level. Adjusted EBITDA of the reportable operating segments do not include certain charges that are presented within corporate activities. These charges include certain restructuring and other business transformation charges that have been incurred to align and reposition the Company to the current reporting structure, acquisition related costs (including transaction costs and integration costs) and share-based compensation charges.
Adjusted EBITDA should not be considered a substitute for, or superior to, financial measures prepared in accordance with GAAP. The financial results prepared in accordance with GAAP and the reconciliations from these results should be carefully evaluated. See “Non-GAAP Reconciliations” in this Item 7 for a reconciliation of adjusted EBITDA to net income. You are encouraged to evaluate each adjustment and the reasons we consider it appropriate for supplemental analysis. In addition, in evaluating adjusted EBITDA, you should be aware that in the future, we may incur expenses similar to the adjustments in the presentation of adjusted EBITDA. Our presentation of adjusted EBITDA should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items. In addition, other companies in our industry or across different industries may calculate adjusted EBITDA differently.

Years Ended September 30, 2021 and September 30, 2020
Consolidated Results
Revenue-Revenue increased $34.9 million, or 2.4%, to $1,464.4 million in the year ended September 30, 2021, from $1,429.5 million in the prior year. Revenue from product sales increased $21.1 million, or 2.5%, to $861.0 million in the year ended September 30, 2021, from $839.9 million in the prior year. Revenue from services increased $13.8 million, or 2.3%, to $603.4 million in the year ended September 30, 2021, from $589.6 million in the prior year.

The increase in organic revenue was driven by higher sales volume, primarily in product sales in the Asia Pacific region across multiple product lines and the EMEA region primarily in the electrochlorination product line, as demand improved following prior year economic closures, and to a year refer to itslesser extent, capital revenue in the chemical processing industry in the second half of the fiscal year. All intercompany transactions have been eliminated. Unless otherwise specified, all dollar amountsIn addition, organic revenue was favorably impacted by higher sales volume in this sectionservice and favorable price realization. These increases were partially offset by lower sales volume in capital revenue related to the timing of completion of prior year projects in the microelectronics end market and lower product sales volume in the Americas region, due to customer site access challenges and delays, primarily in the first half of fiscal 2021, as a result of the COVID-19 pandemic. Favorable foreign currency translation more than offset the reduction in revenue due to the prior year divestiture of the Memcor product line.
Revenue in future periods could be negatively impacted by commodity and material availability constraints caused by global supply chain disruptions, skilled labor shortages, and the timing of projects.
Cost of Sales and Gross Margin-Total gross margin decreased to 31.2% in the year ended September 30, 2021, from 31.5% in the prior year. The following table provides the change in cost of product sales and cost of services, respectively, along with related gross margins:

Cost of services(399.4)33.8 %(391.4)33.6 %
$(1,007.0)31.2 %$(979.7)31.5 %
Gross margin from product sales decreased by 60 bps to 29.4% in the year ended September 30, 2021, from 30.0% in the prior year. The decrease in gross margin was primarily driven by product mix, which was influenced by delays and economic closures related to the COVID-19 pandemic, coupled with higher material, freight, and employment costs driven by inflation, as well as capital project variances. This was partially offset by positive price realization.
Gross margin from services increased by 20 bps to 33.8% in the year ended September 30, 2021, from 33.6% in the prior year. This increase is mainly driven by favorable price/cost as well as continued focus on labor productivity.
We expect continued pressure on gross margin in future periods due to material, freight and labor inflation. Although we expect to continue to partially offset those increasing costs with positive price realization, there can be no assurance that we will be able to do so.

Operating Expenses-Operating expenses increased $21.0 million, or 6.1%, to $363.0 million in year ended September 30, 2021 from $342.0 million in the prior year. Operating expenses are referredcomprised of the following:

Total operating expenses$(363.0)(24.8)%$(342.0)(23.9)%6.1 %
The increase period over period in operating expenses was primarily due to increased employee related expenses, a decrease in thousands. Certainforeign currency translation gains of $7.7 million from the prior period amounts have been reclassifiedwhich is mostly related to conformintercompany loans, increased amortization expense due to acquisitions in the current period, presentation.and an increase in external legal fees. These increases were partially offset by efforts taken by the Company to reduce spending across various areas in response to uncertainties related to the COVID-19 pandemic, such as reduced travel, particularly in the first half of fiscal 2021. Fluctuations in foreign currency translation and labor inflation could impact operating expenses in future periods.
Other Operating Income, Net-Other operating income, net, decreased $55.6 million, to $5.0 million in the year ended September 30, 2021, from $60.6 million in the prior year. The decrease is primarily due to the prior year net pre-tax benefit on the sale of the Memcor product line of $57.7 million, which is net of $8.3 million of discretionary compensation payments to employees in connection with the transaction and $2.1 million in transaction costs incurred. In the year ended September 30, 2021, other operating income, net, includes COVID-19 pandemic subsidies received from the Canadian government, which are not expected to reoccur in future periods.
2. SummaryInterest Expense-Interest expense decreased $9.1 million, or 19.5%, to $37.5 million in the year ended September 30, 2021, from $46.6 million in the prior year. The decrease in interest expense was primarily driven by a $100.0 million debt prepayment in conjunction with the April 2021 refinancing of Significantour senior credit facility, as well as a reduction in the interest rate spread and LIBOR year over year. In addition, there was a $100.0 million debt prepayment that occurred in January 2020. This decrease was partially offset by an additional $3.1 million of fees incurred as a result of the April
39


2021 refinancing, which also resulted in the write off of $1.3 million of deferred financing fees, and a fair value increase of $2.1 million in the Purchase Right liability to acquire the remaining share of Frontier.
Income Tax Expense-Income tax expense was $10.1 million for the year ended September 30, 2021, compared to expense of $7.4 million in the prior year. The increase in tax expense was primarily attributable to an increase in foreign tax expense due to improved profitability in certain countries and the impact of a one-time state tax adjustment for prior periods. The increase in expense was partially offset by a one-time tax benefit for the reversal of the valuation allowance with respect to the Company’s German operating company.

Net Income-Net income decreased by $62.7 million, or 54.8%, to net income of $51.7 million for the year ended September 30, 2021, from $114.4 million in the prior year, as a result of the variances noted above.
Adjusted EBITDA-Adjusted EBITDA is a non-GAAP financial measure. Adjusted EBITDA increased $11.3 million, or 4.7%, to $250.9 million for the year ended September 30, 2021, from $239.6 million for the prior year, primarily driven by sales volume and related gross profit. See “Non-GAAP Reconciliations” in this Item 7 for a reconciliation of adjusted EBITDA to net income.

The increase in organic revenue was driven by higher sales volume, primarily due to growth in service and aftermarket revenue across a variety of end markets as well as favorable price realization. This was partially offset by a net decline in capital revenue, related to the timing of completion of projects in the microelectronics end market. Capital revenue saw volume growth in the second half of the fiscal year, primarily in the chemical processing industry.
Operating profit in the Integrated Solutions and Services segment increased $1.6 million, or 1.1%, to $147.3 million in the year ended September 30, 2021, from $145.7 million in the year ended September 30, 2020.

Operating profit was favorably impacted by sales volume and mix, favorable price/cost, reductions in travel and other discretionary spending as well as COVID-19 pandemic subsidies received from the Canadian government in the current year. These items were partially offset by lower productivity due to customer shutdowns and enhanced safety protocols as a result of the COVID-19 pandemic in the first half of fiscal 2021, some challenges filling open positions and increased operating costs based on changes in allocation methodologies for corporate expenses in the current year.
Adjusted EBITDA is a non-GAAP financial measure. Adjusted EBITDA in the Integrated Solutions and Services segment increased $5.6 million, or 2.6%, to $219.3 million in the year ended September 30, 2021, compared to $213.7 million in the year ended September 30, 2020. The increase was driven by the same factors that impacted operating profit, other than the change in depreciation and amortization. Segment adjusted EBITDA also excludes restructuring and other non-recurring activity. See “Non-GAAP Reconciliations” in this Item 7 for a reconciliation of segment adjusted EBITDA to segment operating profit.
Applied Product Technologies
Revenue in the Applied Product Technologies segment increased $19.2 million, or 4.0%, to $504.5 million in the year ended September 30, 2021, from $485.3 million in the year ended September 30, 2020. The following tables provide the change in revenue by offering and the change in revenue by driver during the years ended September 30, 2021 and 2020 for the Applied Product Technologies segment:

The increase in organic revenue was driven by sales volume growth from product sales in the Asia Pacific region across multiple product lines and the EMEA region primarily in our electrochlorination product line, as demand improved following economic closures that occurred in the prior year due to the COVID-19 pandemic, and to a lesser extent, favorable pricing. This growth was partially offset by declines across multiple product lines in the Americas region as a result of continued customer site access challenges and delays. In addition, the divestiture of the Memcor product line reduced revenue by $14.4 million as compared to the prior year period while foreign currency was favorable by $15.3 million.

Operating profit in the Applied Product Technologies segment decreased $51.4 million, or 38.3%, to $82.9 million in the year ended September 30, 2021, from $134.3 million in the year ended September 30, 2020.
aqua-20210930_g6.jpg
The decline in operating profit was primarily related to the net pre-tax benefit on the sale of the Memcor product line of $57.7 million recognized in the prior year, which was net of $8.3 million of discretionary compensation payments to employees in connection with the transaction and $2.1 million in transaction costs incurred. Operating profit was also impacted by the reduction in sales volume as a result of the sale of the Memcor product line. These declines were partially offset by favorable revenue and operational variances including organic sales volume, product mix and favorable price/cost, as well as the benefits of plant consolidation benefits and higher productivity. However, capital project variances and supply chain challenges unfavorably impacted operating profit.
Adjusted EBITDA is a non-GAAP financial measure. Adjusted EBITDA in the Applied Product Technologies segment increased $6.5 million, or 6.6%, to $105.7 million in the year ended September 30, 2021, compared to $99.2 million in the year ended September 30, 2020. The increase was driven by the same factors that impacted operating profit, other than the change in depreciation and amortization. Segment adjusted EBITDA also excludes other non-recurring activity, including the $57.7 million gain recognized in the prior year related to the divestiture of the Memcor product line. See “Non-GAAP Reconciliations” in this Item 7 for a reconciliation of segment adjusted EBITDA to segment operating profit.
Corporate
Operating loss in Corporate increased $19.3 million, or 17.3%, to $130.9 million in the year ended September 30, 2021, from $111.6 million in the year ended September 30, 2020. The increase period over period was primarily due to increased expenses associated with share-based compensation and legal matters in the current year as well as a decrease in foreign currency translation gains from the prior period, most of which was related to intercompany loans. Reductions in discretionary spending compared to the prior year partially offset these increases.

Liquidity and Capital Resources
Liquidity describes the ability of a company to borrow or generate sufficient cash flows to meet the cash requirements of its business operations, including working capital needs, debt service, acquisitions, other commitments, and contractual obligations. Our principal sources of liquidity are cash generated by our operating activities, borrowings under the 2021 Revolving Credit Facility and financing arrangements related to capital expenditures for equipment used to provide services to our customers. Historically, we have financed our operations primarily from these sources. Our primary cash needs are for day-to-day operations, to pay interest and principal on our indebtedness, to fund working capital requirements and to make capital expenditures.
Our ability to fund our capital needs depends on our ongoing ability to generate cash from operations and access to bank financing and the capital markets. Although the COVID-19 pandemic has not materially impacted our liquidity to date, we plan to continue to evaluate aspects of our spending, including capital expenditures, discretionary spending, and strategic investments in fiscal 2022. We have considered the impacts of the COVID-19 pandemic on our liquidity and capital resources to date, and we do not currently expect it to impact our ability to meet future liquidity needs or affect our ability to continue to comply with our applicable debt covenants. We believe we are currently well-positioned to manage our business and have the ability and sufficient capacity to meet our cash requirements by using available cash, internally generated funds, and borrowing under the 2021 Revolving Credit Facility.
As part of our ongoing efforts to improve our cash flow and related liquidity, we work with suppliers to optimize our terms and conditions, including occasionally extending payment terms. We also facilitate a voluntary supply chain finance program (the “program”) to provide certain of our suppliers with the opportunity to sell receivables due from us to participating financial institutions at the sole discretion of both the suppliers and the financial institutions. A third party administers the program; our responsibility is limited to making payment on the terms originally negotiated with our supplier, regardless of whether the supplier sells its receivable to a financial institution. We do not enter into agreements with any of the participating financial institutions in connection with the program. The range of payment terms we negotiate with our suppliers is consistent, irrespective of whether a supplier participates in the program. The amounts settled through the program and paid to participating financial institutions were $42.0 million and $39.7 million in the year ended September 30, 2021 and 2020, respectively. A downgrade in our credit rating or changes in the financial markets could limit the financial institutions’ willingness to commit to participating in the program.
We expect to continue to finance our liquidity requirements through internally generated funds, borrowings under our revolving credit facility and equipment financing arrangements. We believe that our projected cash flows generated from operations, together with borrowings under the 2021 Revolving Credit Facility and other financing arrangements are sufficient to fund our principal debt payments, interest expense, our working capital needs, and our expected capital expenditures for the next twelve months. Our capital expenditures for the year ended September 30, 2021 and 2020 were
48


$75.3 million and $88.5 million, respectively. However, our budgeted capital expenditures can vary from period to period based on the nature of capital intensive project awards. Our focus on customer outsourced water projects will continue to be a driver of capital expenditures. From time to time, we may enter into financing arrangements related to capital expenditures for equipment used to provide services to our customers. During the year ended September 30, 2021 and 2020, we entered into equipment financing arrangements totaling $37.5 million and $23.3 million, respectively. In addition, we may draw on the 2021 Revolving Credit Facility from time to time to fund or partially fund an acquisition.
As of September 30, 2021, we had total indebtedness of $754.9 million, including $473.8 million of term loan borrowings under the 2021 Credit Agreement, $37.3 million outstanding under the 2021 Revolving Credit Facility, $150.1 million outstanding under the Securitization Facility which includes $0.1 million of accrued interest, $93.4 million in borrowings related to equipment financing and $0.4 million of notes payable related to certain equipment related contracts. We also had $10.1 million of letters of credit issued under our 2021 Revolving Credit Facility as of September 30, 2021.
As of September 30, 2021 and September 30, 2020, we were in compliance with the covenants contained in the 2021 Credit Agreement, including the 2021 Revolving Credit Facility.
2021 Credit Agreement
On April 1, 2021, EWT III entered into the 2021 Credit Agreement among EWT III, as borrower, EWT II, as parent guarantor, the lenders from time to time party thereto, JPMorgan Chase Bank, N.A., as administrative agent and collateral agent, and ING Capital, LLC, as sustainability coordinator. The 2021 Credit Agreement provides for a multi-currency senior secured revolving credit facility in an aggregate principal amount not to exceed the U.S. dollar equivalent of $350.0 million and a discounted senior secured term loan facility relating to a term loan in the amount of $475.0 million (together, the “Senior Facilities”). The 2021 Credit Agreement also provides for a letter of credit sub-facility not to exceed $60.0 million. On April 1, 2021, EWT III borrowed the full amount of $475.0 million under the 2021 Term Loan and $105.0 under the 2021 Revolving Credit Facility. On September 30, 2021, the Company had $473.8 million outstanding under the 2021 Term Loan and $37.3 million outstanding on the 2021 Revolving Credit Facility.
The Senior Facilities are guaranteed by EWT II and certain existing and future direct or indirect wholly-owned domestic subsidiaries of EWT III (together with EWT III, collectively, the “Loan Parties”), and collateralized by a first lien on substantially all of the assets of the Loan Parties, with certain exceptions, including: (i) any equity interest in, and any assets sold to or held by, Evoqua Finance in connection with the Receivables Securitization Program, (ii) any equity interest in, and any assets sold to or held by, any other special purpose entity that is an indirect subsidiary of the Company in connection with any other securitization facility permitted under the 2021 Credit Agreement, and (iii) any real property with a fair market value of $5.0 million or less, when considered individually, or $30.0 million or less when taken together with all other real property owned by the Loan Parties.
With respect to the 2021 Revolving Credit Facility, EWT III is required to pay a commitment fee based on the daily unused portion of the 2021 Revolving Credit Facility, as well as certain other fees to the agents and the arrangers under the Senior Facilities. Subject to the terms of the 2021 Credit Agreement, to the extent not previously paid, any amount owed under the 2021 Revolving Credit Facility will become due and payable in full on April 1, 2026.

With respect to the 2021 Term Loan, EWT III pays quarterly installments of principal of approximately $1.2 million. Subject to the terms of the 2021 Credit Agreement, to the extent not previously paid, any amount owed under the 2021 Term Loan become due and payable in full on April 1, 2028.

Amounts outstanding under the Senior Facilities, at EWT III’s option, bear interest at either (i) a Base Rate determined in accordance with the terms of the 2021 Credit Agreement, (ii) with respect to any amounts denominated in U.S. dollars or Sterling, a LIBO rate, or replacement thereof, as determined in accordance with the terms of the 2021 Credit Agreement, or (iii) with respect to amounts denominated in Euros, the EURIBOR rate, or replacement thereof, as determined in accordance with the terms of the 2021 Credit Agreement. In the case of the 2021 Revolving Credit Facility, an applicable margin based on the consolidated total leverage of EWT III and its restricted subsidiaries, as calculated in accordance
49


with the terms of the 2021 Credit Agreement, is added to the interest rate elected by EWT III; provided that the interest rate may be adjusted if EWT III meets certain metrics for a sustainability price adjustment prior to December 31, 2021. In the case of the 2021 Term Loan, a fixed applicable margin, calculated in accordance with the terms of the 2021 Credit Agreement, is added to the interest rate elected by EWT III.
The net proceeds of the Senior Facilities, together with the net proceeds of the Receivables Securitization Program and cash on hand, were used to repay all outstanding indebtedness, in an aggregate principal amount of approximately $814.5 million, under the 2014 Credit Agreement. The proceeds of the 2021 Revolving Credit Facility may also be used to finance or refinance the working capital and capital expenditures needs of EWT III and certain of its subsidiaries and for general corporate purposes.
The 2021 Credit Agreement is subject to acceleration upon various events of default and contains customary representations, warranties, affirmative covenants, and negative covenants, each substantially similar to those included in the Credit Agreement, including, among other things, a springing maximum first lien leverage ratio of 5.55 to 1.00.
As a result of the refinancing, the Company wrote off approximately $1.3 million of deferred financing fees related to the 2014 Term Loan. In addition, the Company incurred approximately $5.0 million of fees as a result of the refinancing, of which $1.9 million were recorded as deferred financing fees on the Consolidated Balance Sheets and $3.1 million were expensed.
Receivables Securitization Program
On April 1, 2021, Evoqua Finance entered into the Receivables Securitization Program consisting of, among other agreements, (i) the Receivables Financing Agreement among Evoqua Finance, as the borrower, the Receivables Financing Lenders, PNC Bank, as administrative agent, EWT LLC, as initial servicer, and PNC Markets, as structuring agent, pursuant to which the lenders have made available to Evoqua Finance the Securitization Facility in an amount up to $150.0 million and (ii) the Sale Agreement among Evoqua Finance, as purchaser, EWT LLC, as initial servicer and as an originator, and Neptune Benson, Inc., an indirectly wholly-owned subsidiary of the Company, as an originator. Under the Receivables Securitization Program, the Originators, pursuant to the Sale Agreement, are required to sell substantially all of their trade receivables and certain related rights to payment and obligations of the Originators with respect to such receivables (the “Receivables”) to Evoqua Finance, which, in turn, will obtain loans secured by the Receivables from the Receivables Financing Lenders pursuant to the Receivables Financing Agreement. On April 1, 2021, Evoqua Finance borrowed $142.2 million under the Securitization Facility. During the second half of 2021, Evoqua Finance borrowed additional amounts under the Securitization Facility and had $150.1 million outstanding at September 30, 2021, which includes $0.1 million of accrued interest.
Pursuant to the Receivables Securitization Program, the aggregate principal amount of the loans made by the Receivables Financing Lenders will not exceed $150.0 million outstanding, subject to the borrowing base restrictions, unless so increased under the Receivables Financing Agreement. The Receivables Financing Lenders under the Receivables Securitization Program receive interest at LIBOR or LMIR as selected by Evoqua Finance. The Receivables Financing Agreement contains customary LIBOR benchmark replacement language. Additionally, PNC Bank and PNC Markets will receive certain fees as agents, and EWT LLC will receive a fee as servicer of the Receivables.

The Receivables Securitization Program contains certain customary representations, warranties, affirmative covenants, and negative covenants, subject to certain cure periods in some cases, including the eligibility of the Receivables being sold by the Originators and securing the loans made by the Receivables Financing Lenders, as well as customary reserve requirements, events of default, termination events, and servicer defaults. The Receivables Securitization Program matures on April 1, 2024. As of September 30, 2021, we were in compliance with the covenants contained in the Receivables Securitization Program.

Evoqua Water Technologies Corp. is a holding company and does not conduct any business operations of its own. As a result, our ability to pay cash dividends on our common stock, if any, is dependent upon cash dividends and distributions and other transfers from our operating subsidiaries. Under the terms of the 2021 Credit Agreement, our operating subsidiaries are currently limited in their ability to pay cash dividends to us, and we expect these limitations to continue in the future under the terms of any future credit agreement or any future debt or preferred equity securities of ours or of our subsidiaries.
Our indebtedness could adversely affect our ability to raise additional capital, limit our ability to react to changes in the economy or our industry, expose us to interest rate risk and prevent us from meeting our obligations. See Part I, Item 1A, “Risk Factors-Our substantial indebtedness could adversely affect our financial condition and limit our ability to raise additional capital to fund our operations.”

Operating Activities
Cash flows from operating activities can fluctuate significantly from period‑to‑period as working capital needs and the timing of payments for restructuring activities and other items impact reported cash flows.
Net cash provided by operating activities increased to $178.7 million in the year ended September 30, 2021 from $177.0 million in the year ended September 30, 2020.
aqua-20210930_g7.jpg
Operating cash flows in the year ended September 30, 2021 reflect a decrease in net income of $62.7 million from the year ended September 30, 2020, primarily driven by the sale of the Memcor product line.
The add back of non‑cash charges increased operating cash flows by $130.5 million for the year ended September 30, 2021 as compared to an increase to operating cash flows of $45.3 million for the year ended September 30, 2020, resulting in an increase of $85.2 million. This increase was primarily related to the gain on sale of the Memcor product line, which was reflected as a reduction of operating cash flows in the prior year, a decrease in the amount of foreign currency translation gains compared to the prior year, as well as increased share-based compensation and depreciation and amortization compared to the prior period. Non-cash changes also include amortization of deferred financing fees, deferred income taxes and loss on sale of property, plant, and equipment.
The aggregate of receivables, inventories, contract assets, accounts payable and contract billings used $17.5 million in operating cash flows in the year ended September 30, 2021 compared to the providing of $23.1 million in the prior year. The amount of cash flow generated from or used by the above mentioned accounts depends upon how effectively we manage our cash conversion cycle, which is a representation of the number of days that elapse from the date of purchase of raw materials and components to the collection of cash from customers. Our cash conversion cycle can be significantly impacted by the timing of collections and payments in a period.
The aggregate of the remaining assets and liabilities used $18.8 million in operating cash flows in the year ended September 30, 2021 compared to the providing of $39.9 million in operating cash flows in the prior year, resulting in a decrease to cash flows of $58.7 million. This decrease was primarily due to an increase in customer long term receivables and timing of payments associated with large outsourced water contracts.
Income taxes used $2.1 million for the year end September 30, 2021, as compared to the providing of $0.6 million during the prior year.
52


Investing Activities
Net cash used in investing activities decreased $109.2 million to $97.2 million in the year ended September 30, 2021 from net cash provided by investing activities of $12.0 million in the year ended September 30, 2020. This decrease was largely driven by proceeds from the sale of the Memcor product line during the year ended September 30, 2020, in addition to higher cash outflow associated with the Ultrapure and WCSI acquisitions in the current year period as compared to the Frontier acquisition that occurred in the prior period. This decrease was partially offset by lower cash outflow associated with purchase of capital assets and intangibles compared to the prior period. Other activity related to proceeds from the sale of property, plant and equipment remained relatively consistent with the prior period.
Financing Activities
Net cash used in financing activities increased $22.2 million to $130.3 million in the year ended September 30, 2021 from net cash provided by financing activities of $108.1 million in the year ended September 30, 2020. The increase in cash used in financing activities for the year ended September 30, 2021 was primarily due to the debt refinancing activities that occurred in the current year. This increase was partially offset by an increase in cash received from the exercise of stock options in the current period and a decrease in taxes paid related to net share settlements of share-based compensation awards and distribution of dividends to non-controlling interest declined compared to the prior period.
Seasonality

The Company’s fiscal year ends on September 30.


Use of and Estimates
The Consolidated Financial Statements have been preparedpreparation of financial statements in conformityaccordance with GAAP and requirerequires management to make estimates and assumptions. These assumptions about future events that affect amounts reported in our Consolidated Financial Statements and related notes, as well as the reported amounts of assets and liabilities andrelated disclosure of contingent assets and liabilities at the date of the auditedfinancial statements. Management evaluates its accounting policies, estimates and judgments on an on‑going basis. Management bases its estimates and judgments on historical experience, current trends and various other factors that are believed to be relevant at the time Consolidated Financial Statements and the reported amounts of revenue and expenses during the reporting period. Estimates and assumptions are used for, but not limited to: (i) revenue recognition; (ii) allowance for doubtful accounts; (iii) inventory valuation, asset valuations, impairment, and recoverability assessments; (iv) depreciable lives of assets; (v) useful lives of intangible assets; (vi) income tax reserves and valuation allowances; and (vii) product warranty and litigation reserves.

The Company considers a receivable delinquent if it is unpaid after the termour significant accounting policies can be found in Note 2, “Summary of the related invoice has expired. Write‑offs are recorded at the time all collection efforts have been exhausted.
Inventories
Inventories are stated at the lowerSignificant Accounting Policies in Part II, Item 8 of cost or market, where cost is generally determined on the basis of an average or first‑in, first‑out (“FIFO”) method. Production costs comprise direct material and labor and applicable manufacturing overheads, including depreciation charges. The Company regularly reviews inventory quantities on hand and writes off excess or obsolete inventory based on estimated forecasts of product demand and production requirements. Manufacturing operations recognize cost of product sales using standard costing rates with overhead absorption which generally approximates actual cost.
Property, Plant, and Equipment
Property, plant, and equipment is valued at cost less accumulated depreciation. Depreciation expense is recognized using the straight‑line method. Useful lives are reviewed annually and, if expectations differ from previous estimates, adjusted accordingly. Estimated useful lives for major classes of depreciable assets are as follows:
Asset ClassEstimated Useful Life
Machinery and equipment3 to 20 years
Buildings and improvements10 to 40 years
Leasehold improvements are depreciated over the shorter of their estimated useful life or the term of the lease. Costs related to maintenance and repairs that do not extend the assets’ useful life are expensed as incurred.
Acquisitionsthis Annual Report.
Acquisitions are recordedand Purchase Price Allocation
We record acquisitions using the purchase method of accounting. The purchase price of acquisitions is allocated toaccounting in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations, which requires that the tangible and intangible assets acquired and liabilities assumed, based onincluding contingent consideration, be recorded at their estimatedrespective fair valuevalues at the acquisition date. The excess of the acquisitionpurchase price over thosethe estimated fair values of the net tangible and intangible assets acquired is recorded as goodwill. Changes to the acquisition date preliminary fair values prior to the expirationThe application of the purchase method of accounting requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed, in order to properly allocate purchase price consideration. These assumptions and estimates include a market participant’s use of the asset and the appropriate discount rates for a market participant. Our estimates are based on historical experience, information obtained from members of management of the acquired companies and with the assistance of independent third-party appraisal firms. Significant assumptions and estimates include quoted market prices, carrying values, and expected future cash flows, which includes consideration of future growth rates and margins, attrition rates, future changes in technology and brand awareness, loyalty, and the appropriate weighted-average cost of capital and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unanticipated events and circumstances may occur which could affect the accuracy or validity of estimates used in purchase accounting. The purchase price allocation recorded in a business combination may change during the measurement period, which is a period not to exceed 12 monthsone year from the date of acquisition, are recorded as an adjustment toadditional information about conditions existing at the associated goodwill. Contingentacquisition date becomes available.
We record contingent consideration resulting from acquisitions is recordedarrangements at its estimated fair value on a recurring basis as earn-outs related to acquisitions. The fair value of earn-outs related to acquisitions is based on significant unobservable inputs including the acquisition date. These obligations are revalued duringachievement of certain performance metrics. Significant changes in these inputs would result in corresponding increases or decreases in the fair value of the earn-out each subsequent reporting period and changesuntil the related contingency has been resolved. Changes in the fair value of the contingent consideration obligations can result from adjustments in the probability of achieving future development steps, sales targets and profitability and are recorded in General and administrative expenses in the Consolidated Statements of Operations. Acquisition-related expenses and restructuring costs, if any, are recognized separately from the business combination and are expensed as incurred.


Goodwill and Other Intangible AssetsImpairment Review
Goodwill represents purchase consideration paid in a business combination that exceeds the value assigned to the net assets of acquired businesses. Other intangible assets consist of customer‑related intangibles, proprietary technology, software, trademarks and other intangible assets. The Company amortizes intangible assets with definite useful lives on a straight‑line basis over their respective estimated economic lives which range from 1 to 26 years.
The Company reviewsWe review goodwill to determine potential impairment annually during the fourth quarter of itsour fiscal year, or more frequently if events and circumstances indicate that the asset might be impaired. Impairment testing for goodwill is performed at a reporting unit level. A reporting unit is defined as an operating segment or one level below the operating segment. We have determined that we have three reporting units.
The fair values of reporting units are determined using a combination of two methods, one utilizing market revenue and earnings multiples derived from stocks of companies that are engaged in the same or similar lines of business and that are actively traded on a free and open market applied to the corresponding measure of our reporting unit’s financial performance (the market approach - guideline public company (“GPC”) method), and the Company has determined that it has three reporting units. The quantitative impairment testing utilizes bothother derived from discounted cash flow models with estimated cash flows based on internal forecasts of revenue and expenses over a market (guideline public company) andspecified period plus a terminal value (the income (discountedapproach discounted cash flows) method for determining fair value.flows (“DCF”) method). In estimating the fair value of the reporting unit utilizing a discounted cash flow (“DCF”)DCF valuation technique, the Company incorporates itswe incorporate our judgment and estimates of future cash flows, future revenue and gross profit growth rates, terminal value amount, capital expenditures and applicable weighted‑average cost of capital used to discount these estimated cash flows. The estimates and projections used in the estimate of fair value are consistent with the Company’sour current budget and long‑range plans, including anticipated change in market conditions, industry trend,trends, growth rates and planned capital expenditures, among other considerations.
We believe these two approaches are appropriate valuation techniques and we generally weight the two resulting values equally as an estimate of a reporting unit's fair value for the purposes of our impairment testing. However, we may weigh one value more heavily than the other when conditions merit doing so. If market conditions change compared to those used in our market approach, or if actual future results of operations fall below the projections used in the DCF method,
54


our goodwill could become impaired in the future. As a result of our goodwill impairment assessment, we have concluded that none of our goodwill was impaired as of September 30, 2021, and we do not believe the risk of impairment is significant at this time.
Impairment of Long‑Lived Assets
Long‑lived assets, such as property, plant, and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. RecoverabilityConditions that may indicate impairment include, but are not limited to, a significant adverse change in customer demand or business climate that could affect the value of an asset based on indicators of reduced profits or losses generated by the asset or asset group, is measureda product recall, or an adverse action by comparisona regulator, such as a successful challenge of its carryingpatent rights.
When necessary, we record charges for impairments of long-lived assets for the amount to undiscounted future net cash flows the asset or asset group is expected to generate. If the carrying amount of an asset or asset group is not recoverable, the Company recognizes an impairment loss based on the excess of the carrying amount of the asset or asset group over its respective fair valueby which is generally determined as the present value of estimated future cash flows or as the appraised value.
Assets Held for Sale
Assets and liabilities (the “disposal group”) are classified as held for sale when all of the following criteria are met: (i) the Company commits to a plan to sell the disposal group; (ii) it is unlikely the disposal plan will be significantly modified or discontinued; (iii) the disposal group is available for immediate sale in its present condition; (iv) actions required to complete the sale of the disposal group have been initiated; (v) the sale of the asset is probable and the completed sale is expected to occur within one year; and (vi) the disposal group is actively being marketed for sale at a price that is reasonable given its current market value. Upon classification as held for sale, such assets are no longer depreciated or depleted, and a measurement for impairment is performed to determine if there is any excess of carrying value over fair value less costs to sell. Subsequent changes to estimated fair value less the cost to sell will impact the measurement of assets held for sale if the fair value is determined to be less than the carrying value of the assets.
Debt Issuance Costs and Debt Discounts
Debt issuance costs are capitalized and amortized overasset or asset group. Fair value of long-lived assets is determined using an appraised value (obtained with the contractual termassistance of independent third-party appraisal firms) or using an income approach, specifically the discounted cash flow method. Starting with a forecast of the underlying debt using the straight line method which approximates the effective interest method. Debt discounts and lender arrangement fees deducted from the proceeds have been included asexpected future net cash flows associated with an asset or group of assets, we then apply an asset-specific discount rate to arrive at a componentnet present value amount. There were no material impairments of the carrying value of debt and are being amortized to interest expense using the effective interest method.
Beginninglong-lived assets recorded in the first quartercurrent year.
We amortize long-lived assets with finite lives over their estimated useful lives on a straight‑line basis. This amortization methodology best matches the pattern of 2019, the Company entered into an interest rate cap to mitigate risks associated with the Company’s variable rate debt. See Note 12, “Derivative Financial Instruments” for further details. The Company paid $2,235 as a premium for the interest rate cap, whicheconomic benefit that is being amortized to interest expense over its three-year term. The Company recorded $621 of premium amortization to interest expense during the year ended September 30, 2019.expected from definite‑lived assets.
Amortization of debt issuance costs and debt discounts/premiums included in interest expense were $1,991, $2,498 and $4,607 for the years ended September 30, 2019, 2018 and 2017, respectively.
In July 2018, the Company wrote off $2,581 of deferred financing fees and incurred and expensed an additional $1,346 of fees related to the sixth amendment of its First Lien Term Facility in which an additional $150,000 was borrowed.


In November 2017, the Company wrote off $1,844 of deferred financing fees related to a $100,000 prepayment of debt, then subsequently wrote off another $1,150 of fees in December of 2017 due to the refinancing of its First Lien Term Loan. The Company incurred another $2,131 of fees as a result of the December refinancing.
In August 2017, the Company wrote off $1,829 of deferred financing fees related to the extinguishment of debt and incurred another $1,188 of fees related to an amendment of its First Lien Term Facility.
In October 2016, the Company wrote off $2,075 of deferred financing fees related to the extinguishment of debt and incurred another $481 of fees related to a tack-on financing the Company completed in October 2016.
Revenue Recognition
The Company adopted Topic 606, Revenue from Contracts with Customers on October 1, 2018, and recognizes sales of products and services based on the five-step analysis of transactions as provided in Topic 606 which requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for such goods or services.
For sales of aftermarket parts or products with a low level of customization and engineering time, the Company recognizes revenues at the time risks and rewards of ownership pass, which is generally when products are shipped or delivered to the customer as the Company has no obligation for installation. Sales of short‑term service arrangements are recognized as the services are performed, and sales of long‑term service arrangements are typically recognized on a straight‑line basis over the life of the agreement.
For certain arrangements where there is significant customization to the product, the Company recognizes revenue either over time or at a point in time. These products include large capital water treatment projects, systems and solutions for municipal and industrial applications. The nature of the contracts is generally fixed price with milestone billings. The Company recognizes revenue over time if the product has no alternative use and the Company has an enforceable right to payment for the performance completed to date, including a normal profit margin, in the event of termination for convenience. If these two criteria are not met, revenues from these contracts will not be recognized until construction is complete. Contract revenues and cost estimates are reviewed and revised at least quarterly at a minimum and the cumulative effect of such adjustments are recognized in current operations. The amount of such adjustments have not been material. See Note 4, “Revenue” for further details.
Product Warranties
Accruals for estimated expenses related to warranties are made at the time products are sold and are recorded as a component of Cost of product sales in the Consolidated Statements of Operations. The estimated warranty obligation is based on product warranty terms offered to customers, ongoing product failure rates, material usage and service delivery costs expected to be incurred in correcting a product failure, as well as specific obligations for known failures and other currently available evidence. The Company assesses the adequacy of the recorded warranty liabilities on a regular basis and adjusts amounts as necessary.
Shipping and Handling Cost
Shipping and handling costs are included as a component of Cost of product sales.


Derivative Financial Instruments
The Company’s risk-management strategy uses derivative financial instruments to manage interest rate risk and foreign currency exchange rate risk. The Company’s objective in using interest rate derivatives is to add stability to interest expense and manage its exposure to interest rate movements. To accomplish this objective, in November 2018, the Company entered into an interest rate cap which has been designated as a cash flow hedge. The Company uses foreign currency derivative contracts in order to manage the effect of exchange fluctuations on forecasted sales and purchases that are denominated in foreign currencies. To mitigate the impact of foreign exchange rate risk, the Company entered into a series of forward contracts designated as cash flow hedges. The Company does not enter into derivatives for trading or speculative purposes. The Company accounts for derivatives and hedging activities in accordance with ASC Topic No. 815, “Derivatives and Hedging” (Topic No. 815). The Company recognizes all derivatives on the balance sheet at fair value. Changes in the fair values of derivatives that are not designated as hedges are recognized in earnings. If the derivative is designated and qualifies as a hedge, depending on the nature of the hedge, changes in the fair value of the derivatives are either offset against the change in the hedged assets or liabilities through earnings or recognized in Accumulated other comprehensive income (loss), net of tax (“AOCI”) until the hedged item is recognized in earnings.
Income Taxes
The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are provided against deferred tax assets when it is deemed more likely than not that some portion or all of the deferred tax asset will not be realized within a reasonable time period. The Company assesses tax positions using a two‑step process. A tax position is recognized if it meets a more‑likely‑than‑not threshold, and is measured at the largest amount of benefit that is greater than 50.0% percent of being realized. Uncertain tax positions are reviewed each balance sheet date.
Foreign Currency Translation and Transactions
The functional currency for the international subsidiaries is the local currency. Assets and liabilities are translated into U.S. dollars using current rates of exchange, with the resulting translation adjustments recorded in Accumulated other comprehensive loss, net of tax within shareholders’ equity. Revenues and expenses are translated at the weighted‑average exchange rate for the period, with the resulting translation adjustments recorded in the Consolidated Statements of Operations.
Foreign currency translation losses (gains), mainly related to intercompany loans, which aggregated $12,599, $7,018 and $(7,111) for the years ended September 30, 2019, 2018 and 2017, respectively, are primarily included in General and administrative expenses in the Consolidated Statements of Operations.
Research and Development Costs
Research and development costs are expensed as incurred. The Company recorded $15,300, $15,877 and $19,990 of costs for the years ended September 30, 2019, 2018 and 2017, respectively.
Equity‑based Compensation
The Company measures the cost of awards of equity instruments to employees based on the grant‑date fair value of the award. The grant‑date fair value of a non-qualified stock option is determined using the Black‑Scholes model. The fair value of restricted stock unit awards is determined using the closing price of our common stock on date of grant. Compensation costs resulting from equity-based payment transactions are recognized primarily within General and administrative expenses, at fair value over the requisite vesting period on a straight-line basis.
Earnings (Loss) Per Share
Basic earnings (loss) per common share is computed based on the weighted average number of shares of common stock outstanding during the period. Diluted earnings per common share is computed based on the weighted average number


of shares of common stock, plus the effect of diluted common shares outstanding during the period using the treasury stock method. Diluted potential common shares include outstanding stock options.
Retirement Benefits
The Company applies ASC Topic 715, Compensation—Retirement Benefits, which requires the recognition in pension obligations and accumulated other comprehensive income of actuarial gains or losses, prior service costs or credits and transition assets or obligations that have previously been deferred. The determination of retirement benefit pension obligations and associated costs requires the use of actuarial computations to estimate participant plan benefits to which the employees will be entitled. The significant assumptions primarily relate to discount rates, expected long‑term rates of return on plan assets, rate of future compensation increases, mortality, years of service, and other factors. The Company develops each assumption using relevant experience in conjunction with market‑related data for each individual country in which such plans exist. All actuarial assumptions are reviewed annually with third‑party consultants and adjusted as necessary. For the recognition of net periodic postretirement cost, the calculation of the expected return on plan assets is generally derived by applying the expected long‑term rate of return on the market‑related value of plan assets. The fair value of plan assets is determined based on actual market prices or estimated fair value at the measurement date.
Treated Water Outsourcing
Treated Water Outsourcing (“TWO”) is a joint venture between the Company and Nalco Water, an Ecolab company, in which the Company holds a 50% partnership interest. The Company is obligated to absorb all risk of loss up to 100% of the joint venture partner’s equity. As such, the Company fully consolidates TWO as a variable interest entity (“VIE”) under ASC 810, Consolidation. The Company has not provided additional financial support to this entity which it is not contractually required to provide, and the Company does not have the ability to use the assets of TWO to settle obligations of the Company’s other subsidiaries.

The following provides a summary of TWO’s balance sheet as of September 30, 2019 and 2018, and summarized financial information for the years ended September 30, 2019, 2018 and 2017.

Recent Accounting Pronouncements
Accounting Pronouncements Not Yet Adopted
In November 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-19, Codification Improvements to Topic 326, Financial Instruments—Credit Losses which clarifies that receivables from operating leases are accounted for using the lease guidance and not as financial instruments. ASU 2018-19 will be effective for the Company for the quarter ending December 31, 2020, with early adoptions permitted. The Company is currently assessing the impact of adoption on the Company’s Consolidated Financial Statements.


In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808) Clarifying the Interaction between Topic 808 and Topic 606, which clarifies that certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606 when the collaborative arrangement participant is a customer in the context of a unit of account. In addition, unit-of-account guidance in Topic 808 was aligned with the guidance in Topic 606 (that is, a distinct good or service) when an entity is assessing whether the collaborative arrangement or a part of the arrangement is within the scope of Topic 606. ASU 2018-18 should be applied retrospectively to the date of initial adoption of Topic 606 and is effective for the Company for the quarter ending December 31, 2020, with early adoption permitted. The Company is currently assessing the impact of adoption on the Company’s Consolidated Financial Statements.
In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Subtopic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements on fair value measurements. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. ASU 2018-13 will be effective for the Company for the quarter ending December 31, 2020, with early adoption permitted. The Company is currently assessing the impact of adoption on the Company’s disclosures.
In June 2018, the FASB issued ASU 2018‑07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The Company adopted this standard on October 1, 2019 but noted that this adoption did not have an impact on its Consolidated Financial Statements.
In August 2017, the FASB issued ASU 2017‑12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which expands and refines hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements and also made certain targeted improvements to simplify the application of hedge accounting guidance and ease the administrative burden of hedge documentation requirements and assessing hedge effectiveness. The Company adopted this standard on October 1, 2019 but noted that this adoption did not have a material impact on its Consolidated Financial Statements.
In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires entities to use a new forward-looking “expected loss” model that reflects expected credit losses, including credit losses related to trade receivables, and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates which generally will result in the earlier recognition of allowances for losses. ASU 2016-13 will be effective for the Company for the quarter ending December 31, 2020, with early adoption permitted. The Company does not expect the impact of adoption on the Consolidated Financial Statements to be material.
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). ASU 2016-02 requires recognition of operating leases as lease assets and liabilities on the balance sheet, and disclosure of key information about leasing arrangements. Amendments to the standard were issued by the FASB in January, July and December 2018, and March 2019 including certain practical expedients, an amendment that provides an additional and optional transition method to adopt the standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption and certain narrow-scope improvements for lessors. The Company adopted this standard on October 1, 2019 using the modified retrospective approach. In order to comply with Topic 842, the Company completed an assessment of the existing lease portfolio including performing data and policy gap reviews, implemented a new lease accounting system, and updated its processes and accounting policies. The Company expects the impact of adoption on the Consolidated Financial Statements and related disclosures to result in an increase to the Consolidated Balance Sheet in the range of $38 million to $42 million. The Company continues to evaluate certain aspects of lessor accounting, however, it is not expected that this will have a material impact on the Consolidated Financial Statements.


Accounting Pronouncements Recently Adopted
The Company adopted ASU 2017‑09, Scope of Modification Accounting, which amended Accounting Standards Code Topic 718 as of October 1, 2018. The FASB issued ASU 2017‑09 to reduce the cost and complexity when applying Topic 718 and standardize the practice of applying Topic 718 to financial reporting. The ASU was not developed to fundamentally change the definition of a modification, but instead to provide guidance for what changes would qualify as a modification. This adoption did not have a material impact on the Company’s Consolidated Financial Statements.    
The Company adopted ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, as of October 1, 2018. This ASU requires the disaggregation of the service cost component from other components of net periodic benefit cost, clarifies how to present the service cost component and other components of net benefit costs in the Statements of Consolidated Operations and allows only the service cost component of net benefit costs to be eligible for capitalization. The adoption of this guidance did not have an impact on the Consolidated Financial Statements and had a minimal impact to the related disclosures.
The Company adopted ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, as of October 1, 2018. The purpose of this update is to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. The ASU requires the tax effects of all intra-entity sales of assets other than inventory to be recognized in the period in which the transaction occurs. The changes were required to be applied by means of a cumulative-effect adjustment recorded to retained earnings as of the beginning of the year of adoption. This adoption did not have an impact on the Company’s Consolidated Financial Statements.
The Company adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), as of October 1, 2018. ASU 2014-09 clarifies the principles for recognizing revenue when an entity either enters into a contract with customers to transfer goods or services or enters into a contract for the transfer of non-financial assets. The Company utilized the modified retrospective approach and the cumulative effect of adoption resulted in a net decrease to opening retained earnings of $1,582 which was recognized at October 1, 2018. Based on the new guidance, the Company determined that for some of these contracts in which revenue was previously recognized over a period of time, revenue instead needs to be recognized at a point in time. This change is mainly due to the nature of certain products, which in some cases have an alternative use, and the Company’s right to payment in the event of termination for convenience. This adoption did not have a material impact on the Company’s Consolidated Financial Statements. See Note 4, “Revenue” for further details.
3. Acquisitions and Divestitures
Acquisitions support the Company’s strategy of delivering a broad solutions portfolio with robust technology across multiple geographies and end markets. The Company continues to evaluate potential strategic acquisitions of businesses, assets and product lines and believes that capex-like, tuck-in acquisitions present a key opportunity within its overall growth strategy.
On May 25, 2019, the Company acquired all of the issued and outstanding equity securities of ATG UV Technology Limited (“ATG UV”), a leading manufacturer of ultraviolet (“UV”) light disinfection systems used in a wide range of municipal, aquatics and industrial applications, for £5,500 ($6,931) paid in cash at closing. During the year ended September 30, 2019, the Company incurred approximately $193 in acquisition costs, which are included in General and administrative expenses. ATG UV, based in Wigan, UK, is the exclusive technology supplier to Evoqua’s ETS-UVTM product line in North America and the acquisition expands Evoqua’s reach, allowing the Company to serve customers globally. ATG UV is part of the Applied Product Technologies segment.
The accounting for the acquisition has not yet been completed because the Company has not finalized the valuations of the acquired assets, assumed liabilities and identifiable intangible assets, including goodwill. The preliminary opening balance sheet for ATG UV as of September 30, 2019 is summarized as follows:


Current assets$6,296
Property, plant and equipment362
Goodwill1,738
Intangible assets2,277
Total assets acquired10,673
Total liabilities assumed(3,742)
Net assets acquired$6,931
On October 1, 2019, the Company, entered into a Purchase and Sale Agreement with DuPont de Nemours, Inc., pursuant to which the Company will divest their Memcor® low pressure membrane product line (including the product line’s global workforce, its manufacturing site in Windsor, Australia, associated operations and intellectual property) (“Memcor”) to DuPont. In connection with this transaction, DuPont will purchase 100% of the corporate capital of the Australian Subsidiaries and all of the assets related to the Memcor® low pressure membrane product line.
The Company expects to recognize a gain on this transaction upon closing. The agreement to sell Memcor met all of the criteria to classify its assets and liabilities as held for sale in the fourth quarter of 2019, which are included within the Company’s APT segment’s total assets. The sale of Memcor does not represent a strategic shift that will have a major effect on the Company’s operations and financial results and is, therefore, not classified as discontinued operations in accordance with ASU 2014-08. As part of the required evaluation under the held for sale guidance, the Company determined that the approximate fair value less costs to sell the operations exceeded the carrying value of the net assets and no impairment charge was recorded.


The following represents the carrying amounts of assets and liabilities, by major class, classified as held for sale on the Consolidated Balance Sheets at September 30, 2019:
ASSETS 
Cash and cash equivalents$7,291
Receivables, net9,603

The above amounts are excluded from the respective balance sheet footnotes at September 30, 2019. The Company incurred aggregate deal costs related to this divestiture of $2,795 during the year ended September 30, 2019, which are primarily included in General and administrative expenses.
2018 Acquisitions
On August 31, 2018, the Company acquired substantially all of the assets of Le Groupe IsH20Top Inc. (“Isotope”), a Quebec-based provider of high-purity water treatment equipment and systems, equipment maintenance services and service deionization for CAD 3,651 ($2,804); CAD 3,171 ($2,435) cash at closing in addition to earn-out payments one year after the closing. Included in consideration is CAD 226 ($175), which represents the fair value of earn-out payments at the date of acquisition if certain revenue targets are achieved, with the maximum earn-out payment of CAD 480 ($369). Isotope serves the ultrapure pharmaceutical, laboratory, medical, university, industrial and microelectronics markets in the Quebec region and provides its customer base with a variety of solutions including reverse osmosis, deionized water systems and steam purification. The Company incurred approximately $188 of acquisition costs, which are included in General and administrative expenses. Isotope is part of the Integrated Solutions and Services segment and strengthens the Company’s Canadian service capabilities.
On July 26, 2018, the Company acquired all of the issued and outstanding equity securities of ProAct Services Corporation (“ProAct”) and its subsidiaries for $133,772 paid in cash at closing which was funded through incremental borrowings under the Company’s Term Loan. ProAct is a leading provider of on-site treatment services of contaminated water in all 50 states. ProAct will operate within the Company’s Integrated Solutions and Services segment and will continue to be based in Ludington, Michigan with a nationwide service footprint and facilities in California, Florida, Michigan,


Minnesota, New Jersey, Virginia and Texas. ProAct provides an array of expanded offerings across the Company’s existing environmental solutions and enhances its existing service capabilities in mobile/temporary process water and wastewaster treatment, hydrostatic water treatment and coal ash pond remediation. The Company incurred approximately $1,067 of acquisition costs, which are included in General and administrative expenses. The operating results of ProAct have been included in the Company’s Consolidated Statements of Operations since the acquisition date, and resulted in $8,042 and $590 of revenue and net income, respectively, for the year ended September 30, 2018.
The following table presents the unaudited pro forma results for the years ended September 30, 2018 and 2017. The unaudited pro forma financial information combines the results of operations of EWT and ProAct as though the Company had been combined as of the beginning of years ended September 30, 2018 and 2017, and the pro forma information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place at such time. Pro forma results for other acquisitions completed in the year ended September 30, 2018 were determined to not be material.

4. Revenue
Adoption of ASU 2014-09 “Revenue from Contracts with Customers (Topic 606)”
As discussed in Note 2, “Summary of Significant Accounting Policies” the Company adopted ASU 2014-09 on October 1, 2018, using the modified retrospective approach to those contracts that were not completed or substantially complete as of October 1, 2018. Results for the reporting period beginning after October 1, 2018 are presented under Topic 606, while prior period amounts have not been adjusted and continue to be reported in accordance with the Company’s historical accounting under Topic 605. The Company has applied the standard to all open contracts at the date of initial application. The Company recorded a net decrease to opening retained earnings of $1,582 as of October 1, 2018 as a result of the cumulative impact of adopting Topic 606 representing the unfavorable impact to prior results had the over-time revenue recognition for some customer agreements, as discussed below, been applied. In addition, a $6,106 reduction of contract assets, along with an increase of $6,194 to work-in-process inventory and an increase of $1,773 to contract liabilities was recorded as a result of the adoption using the modified retrospective method.
The impact to the Consolidated Statements of Operations as a result of applying Topic 606 was higher Revenue from product sales and services and higher Cost of product sales and services of $2,066 and $1,508, respectively, for the year ended September 30, 2019, as compared to what those amounts would have been under the previous revenue recognition guidance. In addition, the impact on the Consolidated Balance Sheets at September 30, 2019 was lower Inventories, net of $135 as compared to what this amount would have been under the previous guidance. Also, $644 of contract assets were recognized on the consolidated balance sheet at September 30, 2019 related to this over-time revenue recognition. As a result of adopting Topic 606, the Company reevaluated how they view the types of revenue between product sales and services, and their related cost of sales. As a result, the Company reclassified amounts between the two categories on the Consolidated Statements of Operations.


Revenue Recognition
The Company recognizes sales of products and services based on the five-step analysis of transactions as provided in Topic 606. For all contracts with customers, the Company first identifies the contract which usually is established when the customer’s purchase order is accepted or acknowledged. Next the Company identifies the performance obligations in the contract. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. The Company then determines the transaction price in the arrangement and allocates the transaction price to each performance obligation identified in the contract. The Company’s allocation of the transaction price to the performance obligations are based on the relative standalone selling prices for the goods and services contained in a particular performance obligation. The transaction price is adjusted for the Company’s estimate of variable consideration which may include discounts if the Company would fail to meet certain performance requirements, volume discounts or early payment discounts. To estimate variable consideration, the Company utilizes historical experience and known terms. Variable consideration in contracts for the year ended September 30, 2019 was insignificant.
For sales of aftermarket parts or products with a low level of customization and engineering time, the Company recognizes revenuesrevenue at the time risks and rewards of ownership pass, which is generally when products are shipped or delivered to the customer as the Company has no obligation for installation. The Company considers shipping and handling services to be fulfillment activities and as such they do not represent separate performance obligations for revenue recognition. Sales of short‑term service arrangements are recognized as the services are performed.performed, and sales of long‑term service arrangements are typically recognized on a straight‑line basis over the life of the agreement.
For certain arrangements where there is significant customization to the product and for long-term construction-type sales contracts, revenue may be recognized over time.time as performance is completed. In these instances, revenue is recognized using a measure of progress that applies an input method based on costs incurred in relation to total estimated costs. Approximately $326,035, of revenues from construction-type contracts was recognized over time during the year ended September 30, 2019.costs at completion (the percentage-of-completion method). These arrangements include large capital water treatment projects, systems, and solutions for municipal and industrial applications. The nature of the contracts is generally fixed price with milestone billings. In order for revenue to be recognized over a period of time, the product must have no alternative use and the Company must have an enforceable right to payment for the performance completed to date, including a normal profit margin, in the event of termination for convenience. If these two criteria are not met, revenuesrevenue from these contracts will not be recognized until construction is complete. RevenuesContract costs include all direct materials, labor, subcontractors costs and indirect costs related to contract performance. We believe this is the most accurate measure of contract performance because it directly measures the value of the goods and services transferred to the customer.
The percentage-of-completion method of revenue recognition requires us to prepare estimates of cost to complete for contracts in progress. Due to the nature of the work performed on many of our performance obligations, the estimates of total revenue and cost at completion is complex, subject to many variables and may require significant judgment. In making such estimates, judgments are required to evaluate contingencies such as weather, potential variances in schedule and the cost of materials, labor cost and productivity, the impact of change orders, liability claims, contract disputes and achievement of contractual performance standards. As a significant change in one or more of these estimates could affect the profitability of our contracts, we routinely review and update our significant contract estimates through a disciplined project review process in which management reviews the progress and execution of our performance obligations and estimates at completion. Contract revenue and cost estimates are reviewed and revised monthly and the cumulative effect of such adjustments are recognized in current operations. Such changes in contract estimates can result in the
55


recognition of revenue in a current period for performance obligations which were satisfied or partially satisfied in a prior period. Changes in contract estimates may also result in the reversal of previously recognized revenue if the current estimate differs from construction-typethe previous estimate. The amount of such adjustments has not been material.
For contracts formerlywith multiple performance obligations, we allocate the transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. In cases where we do not provide the distinct good or service on a standalone basis, the primary method used to estimate standalone selling price is the expected cost plus a margin approach, under which we forecast our expected costs of satisfying a performance obligation and then add an appropriate margin for that distinct good or service. Our contracts are sometimes modified for changes in contract specifications and requirements. Judgment is required to determine if such modifications result in goods or services that are distinct from the existing contract. For customized products and long-term construction type contracts, most contract modifications are for goods and services that are not distinct due to the significant integration provided in the context of the contract and are accounted for as if they were part of the original contract on a cumulative catch-up basis. We account for contract modifications prospectively when it results in the promise to deliver additional goods and services that are distinct and the increase in price of the contract is for the same amount as the stand-alone selling price of the additional goods or services included in the modification.

Our contracts sometimes contain variable consideration in the form of incentive fees, performance bonuses, award fees, liquidated damages, or penalties. Other contract provisions also give rise to variable consideration such as claims and unpriced change orders that may either increase or decrease the transaction price. We estimate the amount of variable consideration at the most likely amount we expect to be entitled. Variable consideration is included in the transaction price when it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include such amounts in the transaction price are based largely on our assessment of legal enforceability, anticipated performance, and any other information (historical, current, or forecasted) that is reasonably available to us. Variable consideration associated with claims and unapproved change orders is included in the transaction price only to the extent of costs incurred.
Product Warranties
Accruals for estimated expenses related to warranties are made at the time products are sold and are recorded as a component of cost of product sales in the Consolidated Statements of Operations in our Consolidated Financial Statements included elsewhere in this Annual Report. The estimated warranty obligation is based on product warranty terms offered to customers, ongoing product failure rates, material usage and service delivery costs expected to be incurred in correcting a product failure, as well as specific obligations for known failures and other currently available evidence. We assess the adequacy of the recorded warranty liabilities on a regular basis and adjust amounts as necessary.
Deferred Taxes, Valuation Allowances, and Tax Contingencies
Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been recognized in our Consolidated Financial Statements or tax returns. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. We record a valuation allowance to reduce certain deferred tax assets to amounts that are more-likely-than-not to be realized within a reasonable period of time. The factors used to assess the likelihood of realization include our forecast of future taxable income exclusive of reversing temporary differences and carryforwards, future reversals of existing taxable temporary differences and available tax planning strategies that could be implemented to realize the net deferred tax assets.

We consider both positive and negative evidence when evaluating the need for a valuation allowance on our deferred tax assets in accordance with ASC 740, Income Taxes. Available evidence includes historical financial information supplemented by currently available information about future years. Generally, historical financial information is more objectively verifiable than projections of future income and is therefore given more weight in our assessment. We consider cumulative losses in the most recent twelve quarters to be significant negative evidence that is difficult to
56


overcome in considering whether a valuation allowance is required. Conversely, we consider a cumulative income position over the most recent twelve quarters, to be significant positive evidence that a valuation allowance may not be required.

Income tax positions must meet a more-likely-than-not recognition threshold to be recognized. Income tax positions that previously failed to meet the more-likely-than-not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met. Uncertain tax positions are reviewed each balance sheet date. We recognize potential interest and penalties related to unrecognized tax benefits in income tax expense.
Recent Accounting Pronouncements
See Note 2, “Summary of Significant Accounting Policies in Item 8, included in this Annual Report for a complete discussion of recently adopted accounting pronouncements and recently issued accounting pronouncements not yet adopted.
Item 7A. Quantitative and Qualitative Disclosures About Market Risk
Interest Rate Risk
We have market risk exposure arising from changes in interest rates on our senior secured credit facilities, which bear interest at rates that are benchmarked against LIBOR. Based on our overall interest rate exposure to variable rate debt outstanding as of September 30, 2021, a 1% increase or decrease in interest rates would decrease or increase income (loss) before income taxes by approximately $6.8 million. By comparison, a 1% increase or decrease in interest rates would have decreased or increased income (loss) before income taxes by approximately $8.2 million as of September 30, 2020 based on our overall interest rate exposure to variable rate debt outstanding as of that date.
In June 2021, the Company entered into an interest rate swap with an effective date of August 1, 2022 to mitigate risk associated with a variable rate equipment financing. The interest rate swap provides for a fixed rate of 5.25%, has a notional amount of $31 million and a term of seven years.
In May 2020, the Company entered into an interest rate swap to mitigate risks associated with variable rate debt. The interest rate swap has a five year term to hedge the variability of interest payments on the first $500 million of the Company’s senior secured debt and fixes the LIBOR rate on this portion of the senior secured debt at 0.61%.    

Impact of Inflation and Tariffs
Our results of operations and financial condition are presented based on historical cost. Our financial results can be expected to be directly impacted by substantial increases in costs due to commodity cost increases, general inflation, and tariffs, which could lead to a reduction in our revenue as well as decreased margins, as increased costs may not be able to be passed on to customers. We cannot provide any assurance that our results of operations and financial condition will not be materially impacted by inflation in the future. The Company engages in activities to adjust pricing practices with customers to attempt to mitigate the inflationary cost impact incurred. Additionally, while we have experienced supply chain disruptions, to date we have managed restrictions in material availability, delays in shipments or disruptions associated with finding and qualifying alternate suppliers in order to maintain our ability to fulfill customer requirements.
57


Foreign Currency Risk
We have global operations and therefore enter into transactions denominated in various foreign currencies. While we believe we are not susceptible to any material cash impact on our results of operations caused by fluctuations in exchange rates because our operations are primarily conducted in the United States (“U.S.”), if we expand our foreign operations in the future, substantial increases or decreases in the value of the U.S. dollar relative to these other currencies could have a significant impact on our results of operations.
To mitigate cross-currency transaction risk, we analyze significant exposures where we have receipts or payments in a currency other than the functional currency of our operations, and from time to time we may strategically enter into short-term foreign currency forward contracts to lock in some or all of the cash flows associated with these transactions. We also are subject to currency translation risk associated with converting our foreign operations’ financial statements into U.S. dollars. We use short-term foreign currency forward contracts and swaps to mitigate the impact of foreign exchange fluctuations on consolidated earnings. We use foreign currency derivative contracts in order to manage the effect of exchange fluctuations on forecasted sales, purchases, acquisitions, inventory, capital expenditures and certain intercompany transactions that are denominated in foreign currencies. We do not use derivative financial instruments for trading or speculative purposes.
Additionally, we are subject to foreign exchange translation risk due to changes in the value of foreign currencies in relation to our reporting currency, the U.S. Dollar. At this time the Company’s translation risk is primarily concentrated in the exchange rate between the U.S. Dollar and the Euro due to intercompany loans denominated in Euro used to facilitate the capital requirements of our non-U.S. subsidiaries. As the U.S. Dollar strengthens against the Euro, income will generally be negatively impacted, and as the U.S. Dollar weakens, income will generally be positively impacted. At this time these are non-cash impacts. We manage our worldwide cash requirements in accordance with availability in multiple jurisdictions and effectiveness with which those funds can be accessed. As a result, we may access cash from among international subsidiaries and the U.S. when it is cost effective to do so. We continually review our domestic and foreign cash profile, expected future cash generation and investment opportunities and reassess whether there is a need to repatriate funds held internationally to support our U.S. operations. Accordingly, we do not expect translation risk to have a material economic impact on our financial positions or results of operations. Based on our overall foreign currency translation risk exposure related to intercompany loans denominated in Euro as of September 30, 2021 and 2020, a 1% increase or decrease in the Euro to U.S. Dollar exchange rate would decrease or increase income (loss) before income taxes by approximately $1,068 were$1.0 million in both periods.

As explained in Notes 2 and 5 to the consolidated financial statements, when there is significant customization to the products associated with large water treatment projects for municipal and industrial applications, the Company recognizes revenue as performance is completed, using a measure of progress based on costs incurred in relation to estimated costs at completion. Because these estimates are subject to change during the performance of the contract, significant changes in estimates could have a material effect on the Company’s results of operations.
Auditing the total cost estimates for projects where there is significant customization requires complex auditor judgment because of the significant management judgment necessary to develop the estimated total materials and labor costs at completion due to the size, uniqueness of and identified risks for each contract.


How We
Addressed the
Matter in Our
Audit
We obtained an understanding, evaluated the design and tested the operating effectiveness of relevant internal controls over the Company’s process relating to the determination of cost estimates for projects involving significant customer customization. For example, we evaluated the design and tested the operating effectiveness of controls over management’s review of the assumptions and data utilized to estimate costs to complete and the accumulation of actual costs incurred.
To test the total cost estimation for projects, our audit procedures included, among others, obtaining an understanding of the contract, assessing management’s initial total cost estimate, including the materials and labor inputs for a sample of projects, as well as testing the detail of updates made to cost estimates. We analyzed cost estimates, including management’s evaluation of contract clauses and inputs used in cost calculations and assessed the measurement of project completion by performing a physical or virtual site inspection for a sample of in-progress contracts to assess estimates of project progress. Further, we tested cost accumulation for a sample of projects through performing physical and virtual site inspections to assess estimates of project progress, which included performing inquiries of project managers and controllers, as well as through agreement to contract summary data and testing of a sample of costs incurred by comparing amounts recorded to source documents and contracts. We also performed a retrospective review of management’s cost estimates for a sample of completed contracts by comparing initial estimates with the actual historical data to assess management’s ability to estimate.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of
Evoqua Water Technologies Corp.
Opinion on Internal Control over Financial Reporting
We have audited Evoqua Water Technologies Corp.’s internal control over financial reporting as of September 30, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Evoqua Water Technologies Corp. (the Company) maintained, in all material respects, effective internal control over financial reporting as of September 30, 2021, based on the COSO criteria.

As indicated in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of WCSI, which is included in the 2021 consolidated financial statements of the Company and constituted 0.7% of total assets as of September 30, 2021 and 0.3% of net sales for the year then ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of WCSI.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of September 30, 2021 and 2020, the related consolidated statements of operations, comprehensive income (loss), changes in equity and changes in cash flows for each of the three years in the period ended September 30, 2021, and the related notes and the financial statement schedule listed in the Index at Item 15(a)1 to the consolidated financial statements and our report dated November 17, 2021 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

62


Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

1. Description of the Company and Basis of Presentation
Background
Evoqua Water Technologies Corp. (referred to herein as the “Company” or “EWT”) is a holding company and does not conduct any business operations of its own. The Company was incorporated on October 7, 2013. On January 15, 2014, the Company acquired, through its wholly owned subsidiaries, EWT Holdings II Corp. (“EWT II”) and EWT Holdings III Corp. (“EWT III”), the Water Technologies business unit formerly owned by Siemens AG (“Siemens”). On November 6, 2017, the Company completed its initial public offering (“IPO”).
On December 4, 2020, the Company completed a secondary public offering, pursuant to which 12,000 shares of common stock were sold by certain selling shareholders. On February 11, 2021, the Company completed an additional secondary public offering, pursuant to which 16,383 shares of common stock were sold by certain selling shareholders. Upon completion of these offerings, AEA Investors LP disposed of all of their shares of the Company’s common stock. The Company did not receive any proceeds from the sale of shares by the selling shareholders in either of these secondary public offerings.
The Business
EWT provides a wide range of product brands and advanced water and wastewater treatment systems and technologies, as well as mobile and emergency water supply solutions and service contract options through its branch network. Headquartered in Pittsburgh, Pennsylvania, EWT is a multinational corporation with operations in the United States (“U.S.”), Canada, the United Kingdom (“UK”), the Netherlands, Germany, Australia, the People’s Republic of China, Singapore, the Republic of Korea, and India.
The Company is organizationally structured into 2 reportable operating segments for the purpose of making operational decisions and assessing financial performance: (i) Integrated Solutions and Services and (ii) Applied Product Technologies.
Basis of Presentation
The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) from the accounting records of the Company and reflect the consolidated financial position and results of operations for the fiscal years ended September 30, 2021, 2020 and 2019. Unless otherwise specified, references in this section to a year refer to its fiscal year. All intercompany transactions have been eliminated. Unless otherwise specified, all dollar and share amounts in this section are referred to in thousands. Certain prior period amounts have been reclassified to conform to the current period presentation. The Company’s fiscal year ends on September 30 of each year and references in this section to a year refer to the Company’s fiscal year. As such, references to: 2021 relates to the fiscal year ended September 30, 2021, 2020 relates to the fiscal year ended September 30, 2020 and 2019 relates to the fiscal year ended September 30, 2019. Instead, revenues

Correction of Immaterial Errors
During the quarter ended March 31, 2021, the Company identified errors related to the reporting of tax remittances associated with certain equity awards, resulting in a classification error of $18,669 between additional paid in capital and accumulated other comprehensive loss. Management recorded the correction to additional paid in capital and accumulated other comprehensive balances during the quarter ended March 31, 2021. Management considered both the quantitative and qualitative factors within the provisions of SEC Staff Accounting Bulletin No. 99, Materiality, and Staff Accounting Bulletin No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements. Based on evaluation of the errors, management has concluded that the prior period
70


errors were immaterial to the previously issued financial statements. As a result of that classification error, management also identified a second, related immaterial classification error for the understatement of net cash provided by operating cash flows of $18,669 and an overstatement of net cash provided by financing activities of $18,669 for the period from October 1, 2019 to September 30, 2020. The Company has elected to voluntarily correct the identified immaterial classification error in the prior period Consolidated Statements of Changes to Cash Flows to enhance comparability. In doing so, balances in the Consolidated Statements of Changes to Cash Flows included in this Form 10-K have been adjusted to reflect the voluntary immaterial classification error correction of $18,669 between financing and operating in the prior period. Future filings that include prior periods will be corrected, as needed, when filed.
The correction of the above classification errors did not have any effect on the Consolidated Statements of Operations in any of the periods previously presented.
2. Summary of Significant Accounting Policies
Fiscal Year
The Company’s fiscal year ends on September 30.
Use of Estimates
The Consolidated Financial Statements have been prepared in conformity with GAAP and require management to make estimates and assumptions. These assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the audited Consolidated Financial Statements and the reported amounts of revenue and expenses during the reporting period. Estimates and assumptions are used for, but not limited to: (i) revenue recognition; (ii) allowance for credit losses; (iii) inventory valuation, asset valuations, impairment, and recoverability assessments; (iv) depreciable lives of assets; (v) useful lives of intangible assets; (vi) income tax reserves and valuation allowances; and (vii) product warranty and litigation reserves. Estimates are revised as additional information becomes available. Actual results could differ from these estimates.
Cash and Cash Equivalents
Cash and cash equivalents are liquid investments with an original maturity of three or fewer months when purchased.
Accounts Receivable
Receivables are primarily comprised of uncollected amounts owed to the Company from transactions with customers and are reported on the Consolidated Balance Sheets at the outstanding principal amount adjusted for any allowance for credit losses and any charge offs. The Company provides an allowance for credit losses to reduce trade receivables to their estimated net realizable value equal to the amount that is expected to be collected. This allowance is estimated based on historical collection experience, the aging of receivables, specific current and expected future macroeconomic and market conditions, and assessments of the current creditworthiness and economic status of customers. The Company considers a receivable delinquent if it is unpaid after the term of the related invoice has expired. Write‑offs are recorded at the time all collection efforts have been exhausted. The Company reviews its allowance for credit losses on a quarterly basis.
Inventories
Inventories are stated at the lower of cost or net realizable value, where cost is generally determined on the basis of an average or first‑in, first‑out (“FIFO”) method. Production costs comprise direct material and labor and applicable manufacturing overheads, including depreciation charges. The Company regularly reviews inventory quantities on hand and writes off excess or obsolete inventory based on estimated forecasts of product demand and production requirements. Manufacturing operations recognize cost of product sales using standard costing rates with overhead absorption which generally approximates actual cost.
71


Property, Plant, and Equipment
Property, plant, and equipment is valued at cost less accumulated depreciation. Depreciation expense is recognized using the straight‑line method. Useful lives are reviewed annually and, if expectations differ from previous estimates, adjusted accordingly. Estimated useful lives for major classes of depreciable assets are as follows:
Asset ClassEstimated Useful Life
Machinery and equipment3 to 20 years
Buildings and improvements10 to 40 years
Leasehold improvements are depreciated over the shorter of their estimated useful life or the term of the lease. Costs related to maintenance and repairs that do not extend the assets’ useful life are expensed as incurred.
Acquisitions
Acquisitions are recorded using the purchase method of accounting. The purchase price of acquisitions is allocated to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair value at the acquisition date. The excess of the acquisition price over those estimated fair values is recorded as goodwill. Changes to the acquisition date preliminary fair values prior to the expiration of the measurement period, a period not to exceed 12 months from date of acquisition, are recorded as an adjustment to the associated goodwill. Contingent consideration resulting from acquisitions is recorded at its estimated fair value on the acquisition date. These obligations are revalued during each subsequent reporting period and changes in the fair value of the contingent consideration obligations can result from adjustments in the probability of achieving future development steps, sales targets and profitability and are recorded in General and administrative expenses in the Consolidated Statements of Operations. Acquisition-related expenses and restructuring costs, if any, are recognized separately from the business combination and are expensed as incurred.
Goodwill and Intangible Assets
Goodwill represents purchase consideration paid in a business combination that exceeds the value assigned to the net assets of acquired businesses. Intangible assets consist of customer‑related intangibles, proprietary technology, software, trademarks, and other intangible assets. The Company amortizes intangible assets with definite useful lives on a straight‑line basis over their respective estimated economic lives which range from 1 to 26 years.
The Company reviews goodwill and indefinite-lived intangible assets to determine potential impairment annually during the fourth quarter of its fiscal year, or more frequently if events and circumstances indicate that the asset might be impaired. Impairment testing for goodwill is performed at a reporting unit level and the Company has determined that it has three reporting units. The quantitative impairment testing for goodwill utilizes both a market (guideline public company) and income (discounted cash flows) method for determining fair value. In estimating the fair value of the reporting unit utilizing a discounted cash flow (“DCF”) valuation technique, the Company incorporates its judgment and estimates of future cash flows, future revenue and gross profit growth rates, terminal value amount, capital expenditures and applicable weighted‑average cost of capital used to discount these estimated cash flows. The estimates and projections used in the estimate of fair value are consistent with the Company’s current budget and long‑range plans, including anticipated change in market conditions, industry trend, growth rates and planned capital expenditures, among other considerations.
The impairment test for indefinite-lived intangibles consists of a comparison of the asset’s fair value with its carrying value. The fair value is calculated using the income approach DCF method. Impairment is determined to exist when the fair value is less than the carrying value of the assets being tested.
Impairment of Long‑Lived Assets
Long‑lived assets, such as property, plant, and equipment, purchased intangibles and lease right-of-use assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability of the asset or asset group is measured by comparison of its carrying amount to undiscounted future net cash flows the asset or asset group is expected to generate.
72


If the carrying amount of an asset or asset group is not recoverable, the Company recognizes an impairment loss based on the excess of the carrying amount of the asset or asset group over its respective fair value which is generally determined as the present value of estimated future cash flows or as the appraised value.
Debt Issuance Costs and Debt Discounts
Debt issuance costs are capitalized and amortized over the contractual term of the underlying debt using the effective interest method. Debt discounts and lender arrangement fees deducted from the proceeds have been included as a component of the carrying value of debt and are being amortized to interest expense using the effective interest method.
Revenue Recognition
The Company recognizes sales of products and services based on the five-step analysis of transactions as provided in Topic 606, Revenue from Contracts with Customers.
For sales of aftermarket parts or products with a low level of customization and engineering time, the Company recognizes revenue at the time risks and rewards of ownership pass, which is generally when products are shipped or delivered to the customer as the Company has no obligation for installation. The Company considers shipping and handling services to be fulfillment activities and as such they do not represent separate performance obligations for revenue recognition. Sales of short‑term service arrangements are recognized as the services are performed, and sales of long‑term service arrangements are typically recognized on a straight‑line basis over the life of the agreement.
For certain arrangements where there is significant customization to the product and for long-term construction-type sales contracts, willrevenue may be recognized when constructionover time. These arrangements include large capital water treatment projects, systems, and solutions for municipal and industrial applications. The nature of the contracts is complete.generally fixed price with milestone billings. Contract revenuesrevenue and cost estimates are reviewed and revised quarterly at a minimum and the cumulative effect of such adjustments are recognized in current operations. The amount of such adjustments havehas not been material. Contract assets relate to costs incurred to perform in advance of scheduled billings. Contract liabilities relate to payments received in advance of performance under the contracts. Change in contract assets and liabilities are due to the Company’s performance under the contract.
The Company has made accounting policy elections to exclude all taxes by governmental authorities from the measurement of the transaction price and that long-term construction-type sales contracts, or those contracts for products with significant customization for whichthat the total contract price is less than $100 will be recorded at the point in time when the construction is complete or the product is delivered. Approximately $19,815 of revenues from construction-type contracts was recognized on a completed contract method during the year ended September 30, 2019. This represents projects that are either below the $100 threshold, or the product has no alternative use, but the Company does not have an enforceable right to payment.
The Company has also elected the following practical expedients:
Financing Component

As the Company’s standard payment terms are less than one year, the Company has elected the practical expedient not to assess whether a contract has a significant financing component.



Performance Obligations

The Company elects to apply the practical expedient to exclude from this disclosure revenue related to performance obligations if the product has an alternative use and the Company does not have an enforceable right to payment for the performance completed to date, including a normal profit margin, in the event of termination for convenience. The Company maintains a backlog of confirmed orders of approximately $179,341 at September 30, 2019. This backlog represents the aggregate amount of the transaction price allocated to performance obligations that were unsatisfied or partially unsatisfied as of the end of the reporting period. The Company estimates that the majority of these performance obligations will be satisfied within the next twelve months.

complete.
The recording of assets recognized from the costs to obtain and fulfill customer contracts primarily relate to the deferral of sales commissions. The Company’s costs incurred to obtain or fulfill a contract with a customer are classified as non-current assets and amortized to expense over the period of benefit of the related revenue. These costs are recorded within Cost of product sales and services. The amount of contract costs was insignificant at September 30, 2019.2021.
The Company offers standard warranties that generally do not represent a separate performance obligation. In certain instances, a warranty is obtained separately from the original equipment sale or the warranty provides incremental services and as such is treated as a separate performance obligation.
Variable consideration in contracts for the years ended September 30, 2021 and 2020 was insignificant.
Product Warranties
Accruals for estimated expenses related to warranties are made at the time products are sold and are recorded as a component of Cost of product sales in the Consolidated Statements of Operations. The estimated warranty obligation is based on product warranty terms offered to customers, ongoing product failure rates, material usage and service delivery costs expected to be incurred in correcting a product failure, as well as specific obligations for known failures and other currently available evidence. The Company assesses the adequacy of the recorded warranty liabilities on a regular basis and adjusts amounts as necessary.
73


The Company accrues warranty obligations associated with certain products as revenue is recognized. Provisions for the warranty obligations are based upon historical experience of costs incurred for such obligations, adjusted for site‑specific risk factors, and, as necessary, for current conditions and factors. There are significant uncertainties and judgments involved in estimating warranty obligations, including changing product designs, differences in customer installation processes and future claims experience which may vary from historical claims experience.
Leases
The Company accounts for leases in accordance with ASC Topic No. 842, Leases.
Lessee Accounting
The Company leases office space, buildings, vehicles, forklifts, computers, copiers and other assets under non-cancelable operating and finance leases. The Company determines whether an arrangement is or contains a lease at the inception of the arrangement based on the terms and conditions in the contract. A contract contains a lease if there is an identified asset and the Company has the right to control the asset. If the arrangement contains a lease, the Company recognizes a right-of-use (“ROU”) asset and an operating lease liability as of the lease commencement date. Any lease arrangements with a term of 12 months or less are not recorded on the Consolidated Balance Sheets, and lease costs for these arrangements are recognized on a straight-line basis over the lease term. Many of the Company’s lease arrangements provide for an option to exercise one or more renewal terms or to terminate the lease arrangement. The Company includes these options when the Company is reasonably certain to exercise them in the leased term used to establish the ROU asset and lease liabilities. The discount rate utilized in calculating the lease liability is the rate implicit in the lease, if known, otherwise, the incremental borrowing rate (“IBR”) for the expected lease term is used.
Operating lease assets and finance lease assets are included in Operating lease right-of-use assets, net and Property, plant, and equipment, net, respectively, on the Consolidated Balance Sheets. The corresponding operating lease liabilities are included in Accrued expenses and other liabilities and Obligation under operating leases on the Consolidated Balance Sheets. The corresponding finance lease liabilities are included in Accrued expenses and other liabilities and Other non‑current liabilities on the Consolidated Balance Sheets.
Lessor Accounting
The Company generates revenue through the lease of its water treatment equipment and systems to customers. In certain instances, the Company enters into a contract with a customer but must construct the underlying asset prior to its lease. At the time of contract inception, the Company determines if an arrangement is or contains a lease. These contracts generally contain both lease and non-lease components, including installation, maintenance, and monitoring services of the Company-owned equipment, in addition to sale of certain constructed assets. In situations where arrangements contain multiple elements, contract consideration is allocated based on relative standalone selling price. Lease components associated with underlying assets that have an alternative use are classified as operating leases with revenue recognized over time throughout the lease term. Lease components associated with underlying assets that have no alternative are classified as sales-type leases, with point in time revenue recognition at the on-set of the lease, or classified as financing transactions, with over time revenue recognition at the on-set of the construction of the underlying assets. In order for a component to be separate, the customer would be able to benefit from the right of use of the component separately or with other resources readily available to the customer and the right of the use is not highly dependent or highly interrelated with the other rights to use the other underlying assets or components.
Shipping and Handling Cost
Shipping and handling costs are included as a component of Cost of product sales.
Derivative Financial Instruments
The Company’s risk-management strategy uses derivative financial instruments to manage interest rate risk, foreign currency exchange rate risk, equity price risk and commodity price risk. The Company does not enter into derivatives for trading or speculative purposes.
74


The Company accounts for derivatives and hedging activities in accordance with ASC Topic No. 815, Derivatives and Hedging (“Topic No. 815”). As required by Topic No. 815, the Company records all derivatives on the Consolidated Balance Sheets at fair value and adjusts to market on a quarterly basis. Changes in the fair value of derivatives are recorded in earnings or Accumulated other comprehensive income (loss), net of tax (“AOCI”), based on whether the instrument is designated and effective as a hedge transaction. Gains and losses on derivative instruments recorded to AOCI are reclassified to earnings in the period the hedged item affects earnings.
The Company’s interest rate swaps are valued based on readily-observable market inputs, such as quotations on interest rates and LIBOR yield curves at the reporting date. The Company’s foreign currency forward contracts are valued based on quoted forward foreign exchange prices and spot rates at the reporting date. The Company’s total return swaps are valued using closing stock prices at the reporting date.
Income Taxes
The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are provided against deferred tax assets when it is considered more likely than not that some portion or all of the deferred tax asset will not be realized within a reasonable time period. The Company assesses tax positions using a two‑step process. A tax position is recognized if it meets a more‑likely‑than‑not threshold and is measured at the largest amount of benefit that has a greater than 50% percent likelihood of being realized. Uncertain tax positions are reviewed each balance sheet date.
Foreign Currency Translation and Transactions
The functional currency for the international subsidiaries is the local currency. Assets and liabilities are translated into U.S. dollars using current rates of exchange, with the resulting translation adjustments recorded in Accumulated other comprehensive loss, net of tax within shareholders’ equity. Revenue and expenses are translated at the weighted‑average exchange rate for the period, with the resulting translation adjustments recorded in the Consolidated Statements of Operations.
Foreign currency translation (gains) losses, mainly related to intercompany loans, which aggregated ($927), $(8,216) and $12,599 for the years ended September 30, 2021, 2020 and 2019, respectively, are primarily included in General and administrative expenses in the Consolidated Statements of Operations.
Research and Development Costs
Research and development costs are expensed as incurred.
Equity‑based Compensation
The Company measures the cost of awards of equity instruments to employees based on the grant‑date fair value of the award. The grant‑date fair value of a non-qualified stock option is determined using the Black‑Scholes model. The grant-date fair value of restricted stock unit awards is determined using the closing price of the Company’s common stock on date of grant. As there is a market condition associated with the award, the grant-date fair value of the performance share units was determined using a Monte Carlo Simulation. Compensation costs resulting from equity-based payment transactions are recognized primarily within General and administrative expenses, at fair value over the requisite vesting period on a straight-line basis.
Earnings (Loss) Per Share
Basic earnings (loss) per common share is computed based on the weighted average number of shares of common stock outstanding during the period. Diluted earnings per common share is computed based on the weighted average number of shares of common stock, plus the effect of diluted common shares outstanding during the period using the treasury stock method. Diluted potential common shares include outstanding stock options.
75


Retirement Benefits
The Company applies ASC Topic 715, Compensation—Retirement Benefits, which requires the recognition in pension obligations and accumulated other comprehensive income of actuarial gains or losses, prior service costs or credits and transition assets or obligations that have previously been deferred. The determination of retirement benefit pension obligations and associated costs requires the use of actuarial computations to estimate participant plan benefits to which the employees will be entitled. The significant assumptions primarily relate to discount rates, expected long‑term rates of return on plan assets, rate of future compensation increases, mortality, years of service, and other factors. The Company develops each assumption using relevant experience in conjunction with market‑related data for each individual country in which such plans exist. All actuarial assumptions are reviewed annually with third‑party consultants and adjusted as necessary. For the recognition of net periodic postretirement cost, the calculation of the expected return on plan assets is generally derived by applying the expected long‑term rate of return on the market‑related value of plan assets. The fair value of plan assets is determined based on actual market prices or estimated fair value at the measurement date.
Recent Accounting Pronouncements
Accounting Pronouncements Not Yet Adopted
In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, and also issued subsequent amendments to the initial guidance (collectively, “Topic 848”). Topic 848 became effective immediately and expires on December 21, 2022. Topic 848 allows eligible contracts that are modified to be accounted for as a continuation of those contracts, permits companies to preserve their hedging accounting during the transition period and enables companies to make a one-time election to transfer or sell held-to-maturity debt securities that are affected by rate reform. Topic 848 provides optional expedients and exceptions for contracts, hedging relationships and other transactions that reference the London Inter-Bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform if certain criteria are met. The Company is currently assessing the impact of adoption on the Company’s Consolidated Financial Statements and related disclosures.
Accounting Pronouncements Recently Adopted
The Company adopted ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments on October 1, 2020 (“ASU 2016-13”). ASU 2016-13 requires entities to use a new forward-looking “expected loss” model that reflects expected credit losses, including credit losses related to trade receivables, and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates, which generally will result in the earlier recognition of allowances for losses. The Company adopted ASU 2016-13 using a modified retrospective approach and determined that there was no cumulative-effect adjustment to its beginning Retained deficit on the Consolidated Balance Sheets. The adoption of this standard did not have a material impact on the Company’s Consolidated Financial Statements. See Note 7, “Accounts Receivable” for further details and related disclosures.

3. Variable Interest Entities
Treated Water Outsourcing (“TWO”) is a joint venture between the Company and Nalco Water, an Ecolab company, in which the Company holds a 50% partnership interest. The Company is obligated to absorb all risk of loss up to 100% of the joint venture partner’s equity. As such, the Company fully consolidates TWO as a variable interest entity (“VIE”) under ASC Topic No. 810, Consolidation. The Company has not provided, and is not contractually required to provide, additional financial support to this entity, and the Company does not have the ability to use the assets of TWO to settle obligations of the Company’s other subsidiaries.
The following provides a summary of TWO’s balance sheet as of September 30, 2021 and September 30, 2020 and summarized financial information for the fiscal years ended September 30, 2021, 2020 and 2019.

On October 1, 2019, the Company acquired a 60% investment position in San Diego-based Frontier Water Systems, LLC (“Frontier”). The Frontier acquisition is a VIE because it has insufficient equity to finance its activities due to key assets being assigned to the Company upon acquisition.  The Company is the primary beneficiary of Frontier because the Company has the power to direct the activities that most significantly affect Frontier’s economic performance.
In addition, the Company entered into an agreement to acquire the remaining 40% interest in Frontier on or prior to March 30, 2024. This agreement (a) gave holders of the remaining 40% interest in Frontier (the “Minority Owners”) the right to sell to Evoqua up to approximately 10% of the outstanding equity in Frontier at a predetermined price, which right was exercisable by the Minority Owners between January 1, 2021 and February 28, 2021 (the “Option”), and (b) obligates the Company to purchase and the Minority Owners to sell all of the Minority Owners’ remaining interest in Frontier at the fair market value at the time of sale on or prior to March 30, 2024 (the “Purchase Right”). The Purchase Right may be exercised early by the Minority Owners. The agreement to purchase the remaining interest was determined to be financing due to the mandatory Purchase Right, as per ASC Topic 480, Distinguishing Liabilities From Equity, and as such, the Company recognized a liability for the remaining 40% interest. The Minority Owners exercised the Option, and on April 8, 2021, the Company completed the purchase of an additional 8% of the outstanding equity in Frontier for approximately $1,490. As a result, the Company’s ownership position in Frontier increased to 68%.
Additionally, the Company fully consolidates Frontier as a VIE under ASC Topic No. 810, Consolidation.

5.6. Fair Value Measurements
As of September 30, 20192021 and 2018,2020, the fair values of cash and cash equivalents, accounts receivable and accounts payable approximateapproximated carrying values due to the short maturity of these items.
The Company measures the fair value of pension plan assets and liabilities, deferred compensation and plan assets and liabilities on a recurring basis pursuant to ASC Topic 820. ASC Topic 820 establishes a three‑tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include:
Level 1: Quoted prices for identical instruments in active markets.
Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model‑derived valuations whose inputs are observable or whose significant value driver is observable.
Level 3: Unobservable inputs in which little or no market data is available, therefore requiring an entity to develop its own assumptions.
The following table presents the Company’s financial assets and liabilities at fair value. The fair values related to the pension assets are determined using net asset value (“NAV”) as a practical expedient, or by information categorized in the fair value hierarchy level based on the inputs used to determine fair value. The reported carrying amounts of deferred compensation assets and liabilities and debt approximate their fair values. The Company uses interest rates and other relevant information generated by market transactions involving similar instruments to measure the fair value of these assets and liabilities, therefore, all are classified as Level 2 within the valuation hierarchy. For the years ended September 30, 2019 and 2018, there were no transfers between Level 1 and 2 of the fair value hierarchy.

The pension plan assets and liabilities and deferred compensation assets and liabilities are included in other non-current assets and other non-current liabilities on the Consolidated Balance Sheets at September 30, 20192021 and 2018.2020. The unrealized gain on mutual funds was $445 at September 30, 2021.
The Company records contingent consideration arrangements at fair value on a recurring basis and the associated balances presented as of September 30, 20192021 and 20182020 are earn-outs related to acquisitions. See Note 3,4, “Acquisitions and Divestitures” for further discussion regarding the earn-outs recorded for specific acquisitions. The fair value of earn-outs related to acquisitions is based on significant unobservable inputs including the achievement of certain performance metrics.


Significant changes in these inputs would result in corresponding increases or decreases in the fair value of the earn-out each period until the related contingency has been resolved. Changes in the fair value of the contingent consideration obligations can result from adjustments in the probability of achieving future development steps, sales targets and profitability and are recorded in General and administrative expenses in the Consolidated Statements of Operations.
A rollforward of the activity in the Company’s fair value of earn-outs related to acquisitions is as follows:

Pursuant to the acquisition of Frontier, the Company recorded a liability for the Option and Purchase Right to purchase the remaining 40% interest. The fair value of the options is based upon significant unobservable inputs including future earnings and other market factors. Significant changes in these inputs would result in corresponding increases or decreases in the fair value of the options each period until the purchase of the remaining 40% interest has occurred. Changes in the fair value can result from earnings achieved over the passage of time and will be recorded in Interest expense in the Consolidated Statements of Operations. The Minority Owners exercised the Option, and on April 8, 2021 the Company completed the purchase of an additional 8% of the outstanding equity in Frontier for approximately $1,490. During the year ended September 30, 2021, the Company recorded an increase in the fair value of the Purchase Right liability for $2,056, which was recorded to Interest expense on the Consolidated Statements of Operations. As of September 30, 2021, $8,305 is included in Other non‑current liabilities related to the Purchase Right on the Consolidated Balance Sheets. As of September 30, 2020, $7,739 is included in Other non‑current liabilities related to the Purchase Right on the Consolidated Balance Sheets.

Interest Rate Risk Management
The Company is subject to market risk exposure arising from changes in interest rates on the senior secured credit facilities as well as variable rate equipment financings, which bear interest at rates that are indexed against LIBOR. The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to mitigate its exposure to rising interest rates.
To accomplish these objectives, on June 30, 2021, the Company entered into an interest rate cap,swap with an effective date of August 1, 2022 to mitigate risk associated with a variable rate equipment financing. The interest rate swap provides for a fixed rate of 5.25%, has a notional amount of $31,000 and a term of seven years. The interest rate swap has been designated as a cash flow hedge,hedge.
On May 22, 2020, the Company entered into an interest rate swap to mitigate risks associated with variable rate debt effective November 28, 2018.debt. The LIBOR interest rate cap coversswap became effective on June 30, 2020, has a notional amountterm of $600,000five years to hedge the variability of interest payments on the first $500,000 of the Company’s senior secured debt is effective for a periodand fixes LIBOR on this portion of three years andthe senior secured debt at 0.61%. The interest rate swap has a strike rate of 3.5%. Interest rate capsbeen designated as a cash flow hedges involve the receipt of stipulated amounts from a counterparty if interest rates rise above the strike rate defined in the contract. The premium paid for the interest rate cap was $2,235 and is being amortized to interest expense over its three-year term using the caplet method. The unamortized premium was $1,614 at September 30, 2019, of which $745 is included in Prepaid and other current assets and the remaining $869 is included in Other non‑current assets. The Company recorded $621 of premium amortization to interest expense during the year ended September 30, 2019, respectively.hedge.
Foreign Currency Risk Management
The Company’s functional currency is the U.S. dollar. By operating internationally, the Company is subject to foreign currency risk from transactions denominated in currencies other than the U.S. dollar (“foreign currencies”). To mitigate cross-currency transaction risk, the Company analyzes significant exposures where it has receipts or payments in a currency other than the functional currency of its operations, and from time to time may strategically enter into short-term foreign currency forward contracts to lock in some or all of the cash flows associated with these transactions. The Company is also subject to currency translation risk associated with converting the foreign operations’ financial results into U.S. dollars. The Company uses foreign currency derivative contracts in order to manage the effect of exchange fluctuations on forecasted sales and purchases that are denominated in foreign currencies. To mitigate the impact of foreign exchange rate risk, the Company entered into a series of forward contracts designated as cash flow hedges. As of September 30, 2019,2021, the notional amount of the forward contracts heldwas $7,076.

Equity Price Risk Management
The Company is exposed to sell foreign currenciesvariability in compensation charges related to certain deferred compensation obligations to employees. Equity price movements affect the compensation expense as certain investments made by the Company’s employees in the deferred compensation plan are revalued. Although not designated as accounting hedges, the Company utilizes derivatives such as total return swaps to economically hedge this exposure and offset the related compensation expense. As of September 30, 2021, the notional amount of the total return swaps was $12,917.$4,540.
Credit Risk Management
The counterparties to the Company’s derivative contracts are highly rated financial institutions. The Company regularly reviews the creditworthiness of its financial counterparties and does not expect to incur a significant failure of any counterparties to perform under any agreements. The Company is not subject to any obligations to post collateral under derivative instrument contracts. The Company records all derivative instruments on a gross basis in the Consolidated Balance Sheets. Accordingly, there are no offsetting amounts that net assets against liabilities.


Derivatives Designated as Cash Flow Hedges
The Company accounts for derivatives and hedging activities in accordance with ASC Topic No. 815, “Derivatives and Hedging” (Topic No. 815). As required by Topic No. 815, the Company records all derivatives on the balance sheet at fair value and adjusts to market on a quarterly basis. The Company’s interest rate cap is valued based on readily observable market inputs, such as quotations on interest rates and LIBOR yield curves at the reporting date. The Company’s foreign currency forward contracts are valued based on quoted forward foreign exchange prices and spot rates at the reporting date. For a derivative that is designated as a cash flow hedge, changes in the fair value of the derivative are recognized in AOCI to the extent the derivative is effective at offsetting the changes in the cash flows being hedged until the hedged item affects earnings. To the extent there is any hedge ineffectiveness, changes in fair value relating to the ineffective portion are immediately recognized in earnings in the Consolidated Statements of Operations. The Company recorded no hedge ineffectiveness during the year ended September 30, 2019. The Company does not use derivative financial instruments for trading or speculative purposes.

TheCertain of the Company’s employees in Germany also participate in a defined benefit plan. Assets equaling the plan’s accumulated benefit obligation were transferred to a German defined benefit plan sponsored by the Company upon the acquisition of EWT from Siemens.

Deferred Compensation
On April 1, 2014, the Company adopted a non-qualified deferred compensation plan for certain highly compensated employees. The Plan matches, on a dollar-for-dollar basis, up to the first 6% of a participants’participant’s pay. The Company’s obligation under the plan represents an unsecured promise to pay benefits in the future. In the event of bankruptcy or insolvency of the Company, assets of the plan would be available to satisfy the claims of general creditors. To increase the security of the participants’ deferred compensation plan benefits, the Company has established and funded a grantor trust (known as a rabbi trust). The rabbi trust is specifically designed so that assets are available to pay plan benefits to participants in the event the Company is unwilling or unable to pay the plan benefits for any reason other than bankruptcy or insolvency. As a result, the Company is prevented from withdrawing or accessing assets for corporate needs. Plan participants choose to receive a return on their account balances equal to the return on the various investment options. The rabbi trust assets are primarily invested in mutual funds and insurance contracts of which the rabbi trust is the owner and beneficiary.

Health Benefit Plan
The Company maintains a qualified employee health benefit plan in the U.S. and is self‑funded by the Company with respect to claims up to a certain amount. The plan requires contributions from eligible employees and their dependents.

Accounting standards require that deferred tax assets be reduced by a valuation allowance if, based on all available evidence, it is considered more likely than not that some portion or all of the recorded deferred tax assets will not be realized in future periods. This assessment requires significant judgement,judgment, and in making this evaluation, the Company considers all available positive and negative evidence, including the potential to carryback net operating losses and credits, the future reversal of certain taxable temporary differences, actual and forecasted results, and tax planning strategies that are both prudent and feasible. A significant piece of objective negative evidence evaluated wasis the cumulative income or loss incurred over recent years including the three‑year period ended September 30, 2019. Such objective2021. The U.S. group was in a three-year cumulative loss at September 30, 2019 but was no longer in a three-year cumulative loss position at September 30, 2020, primarily due to the sale of the Memcor business. The Company believes the favorable evidence limitsof no longer being in a three-year cumulative loss is outweighed by the abilitylosses of the U.S. group and the significant global economic uncertainty due to consider other subjective evidence, such as the Company’s projections for future growth.COVID-19 health crisis. Our German operations have demonstrated strong profitability in the most recent three years, are cumulatively profitable, and have fully utilized their net operating loss carryforwards.
After considering all available evidence, both positive and negative, management determined that a valuation allowance was necessary in certain jurisdictions. As of September 30, 2019,2021, the company maintainsCompany reversed the German valuation allowance and continues to maintain a full valuation allowance against its net deferred tax assets (excluding certain deferred tax liabilities including those related to indefinite lived intangibles) in the U.S., Germany, and the UK. A partial valuation allowance iscontinues to be maintained in the Netherlands related to deferred tax assetsa net operating loss generated prior to the Magneto acquisition that are not expected to be realized.as well as certain foreign tax credits.

Subject to the assets held for sale, theThe Company does not anticipate that it will dispose any of its foreign subsidiaries in the foreseeable future and as such has not recorded a U.S. deferred tax asset where the tax basis exceeds the financial reporting basis of these investments. Additionally, the Company has not provided a U.S. deferred tax liability on the excess of financial reporting over tax basis of its investments.
As of September 30, 2019, 20182021, 2020 and 2017,2019, undistributed earnings of non-U.S. affiliates were approximately $49,480, $36,879$77,709, $53,766, and $5,218,$49,480, respectively, which are considered to be indefinitely reinvested. Upon distribution of these earnings the Company may be subject to U.S. income taxes and foreign withholding taxes. The amount of taxes that may be payable on remittance of these earnings is dependent on the tax laws and profile of the Company at that time and the availability of foreign tax credits in the year in which such earnings are remitted. Therefore, it is not practicable to estimate the amount of taxes that may be payable when these earnings are remitted in the future.
The Company utilizes the more-likely-than-not standard in recognizing a tax benefit in its financial statements. For the yearyears ended September 30, 2021, 2020, and 2019, the Company had unrecognized tax benefits. The Company did not have unrecognized tax benefits for the years ended September 30, 2018 or 2017.of $1,123, $1,050, and $1,075 respectively.

Effects of the Tax Cuts and Jobs Act
The Tax Cuts and Jobs Act (the Tax Act) introduced new provisions that were effective January 1, 2018 and changed how certain provisions are calculated beginning with the year ended September 30, 2018. These provisions included additional limitations on certain meals and entertainment expenses, and the inclusion of commissions and performance-based compensation in determining the excessive compensation limitation applicable to certain employees, a limitation on the current deductibility of net interest expense in excess of 30% of adjusted taxable income, a limitation on the use of net operating losses generated after fiscal 2018 to 80% of taxable income, an incremental tax (base erosion anti-abuse tax or BEAT) on excessive amounts paid to foreign related parties. These new provisions did not have a material impact to the Company’s tax expense. The Tax Act also created a provision known as GILTI that imposes a tax on certain earnings of foreign subsidiaries. The Company has elected to account for GILTI tax in the period in which it is incurred, and therefore has not provided any deferred tax impacts of GILTI in its Consolidated Financial Statements for the year ended September 30, 2018.
Amounts recorded where accounting is complete principally related to the reduction in the U.S. corporate income tax rate to 21%, which resulted in the Company reporting an income tax benefit of $3,641 to remeasure deferred taxes liabilities associated with indefinite lived intangible assets that will reverse at the new 21% rate. Absent this deferred tax liability, the Company is in a net deferred tax asset position that is fully offset by a valuation allowance. Though the tax effected net deferred tax asset changed, the movement was offset by movement in the valuation allowance with a net tax effect of $0.
17.18. Share-Based Compensation
The Company designs equity compensation plans to attract and retain employees while also aligning employees’ interests with the interests of the Company’s shareholders. In addition, members of the Company’s Board of Directors (the “Board”) participate in equity compensation plans in connection with their service on the Company’s Board.
The Company established the Evoqua Water Technologies Corp. Stock Option Plan (the “Stock Option Plan”) shortly after the acquisition date of January 16, 2014. The plan allows certain management employees and the Board to purchase shares in Evoqua Water Technologies Corp. Under the Stock Option Plan, the number of shares available for award was 11,083. As of September 30, 2019,2021, there were approximately 1,7042,089 shares available for future grants, however,


the Company does not currently intend to make additional grants under the Stock Option Plan.
In connection with the IPO, the Board adopted and the Company’s shareholders approved the Evoqua Water Technologies Corp. 2017 Equity Incentive Plan (the(or the “Equity Incentive Plan”), under which equity awards may be made in the respect of 5,100 shares of common stock of the Company. Under the Equity Incentive Plan, awards may be granted in the form of options, restricted stock, restricted stock units, (“RSU”), stock appreciation rights, dividend equivalent rights, share awards and performance-based awards (including performance share units and performance-based restricted stock). Upon adoption of the Equity Incentive Plan, 5,100 shares of common stock of the Company were reserved for issuance thereunder. On February 18, 2020, the Company’s shareholders approved the amendment and restatement of the Equity Incentive Plan in order to increase the number of shares of common stock reserved for issuance thereunder by 5,000 shares and incorporate other changes.
On May 18, 2021 (the “Grant Date”), the Compensation Committee of the Board approved and the Company granted special one-time awards of 234 restricted stock units (“Special RSUs”) and 469 performance share units (“Special PSUs”), at a target award level, under the Equity Incentive Plan to certain executive officers of the Company. Subject to the applicable executive officer’s continued employment with the Company and the terms and conditions of the Equity
103


Incentive Plan and the related award agreement, the Special RSUs will vest ratably over a three-year period on each annual anniversary of the Grant Date, and the Special PSUs will be earned incrementally in three tranches of 25%, 25%, and 50% after one-, two-, and three-year performance periods, respectively, and will cumulatively be paid, if earned, after the end of the three-year performance period ending on May 18, 2024, based on the Company’s total stockholder return (“TSR”) compared to peer water companies, including certain U.S.-listed companies included in the S&P Global Water Index (the “Peer Companies”). Each tranche of the Special PSUs reflects the right to receive between 50% and 100% of the shares underlying such tranche based on the Company’s TSR as compared to the Peer Companies (“Relative TSR”) for the applicable performance period. Subject to certain exceptions provided in the award agreements in the event of death, disability, or change in control, for each tranche, Special PSUs will be earned as follows: 100% if Relative TSR for the period is at the 80th percentile or above; 50% if Relative TSR for the period is at the 60th percentile; and 0% if Relative TSR is below the 60th percentile. Linear interpolation will be used to determine the percentage of each tranche earned when Relative TSR is between the 60th percentile and the 80th percentile for the applicable performance period. The payout for each tranche of the Special PSUs is capped at 100% even if Relative TSR exceeds the 80th percentile for the applicable period. If the Company’s TSR is negative for any performance period, the number of Special PSUs that may vest for the corresponding tranche will be capped at 50% of the amount that otherwise would have been earned for the period.
As of September 30, 2019,2021, there were approximately 2,0084,340 shares available for grants under the Equity Incentive Plan.
In addition to the establishment of the Equity Incentive Plan, in connection with the IPO, the Company entered into RSU agreements with each of the executive officers and certain other key members of management. Pursuant to the RSU agreements, recipients received, in the aggregate 1,197 stock-settled RSUs, the aggregate value of which equals $25,000. The RSUs will vest and settle in full upon the second anniversary of the IPO (the “Vesting Date”), subject to the grantee’s continued employment with the Company or any of its subsidiaries through the Vesting Date; provided, however, that in the event that a Change in Control (as defined in the RSU agreements) occurs prior to the Vesting Date, the RSUs will vest and settle in full upon the date of such Change in Control, subject to the grantee’s continued employment with the Company or any of its subsidiaries through the Change in Control date. In the event that the grantee’s employment is terminated for any reason prior to the Vesting Date, the grantee will forfeit each of his or her RSUs for no consideration as of the date of such termination of employment; provided, that, if the grantee’s employment is terminated without Cause (as defined in the RSU agreement) prior to the Vesting Date, the RSUs will vest and settle in full upon the Vesting Date as though the grantee had remained employed through such date.
Option awards are granted at various times during the year, generally vest ratably at 25% per year, and are exercisable at the time of vesting. The options granted have a ten-year contractual term.

As a result, in addition to Company data, the Company has used historic data from public disclosures of comparable companies which the Company believes to be representative of its own expected employee behaviors.
The Company estimates the fair value of each stock option award on the grant date using the Black-Scholes valuation model incorporating the assumptions noted in the following table. Option valuation models require the input of highly subjective assumptions, and changes in assumptions used can materially affect the fair value estimate.
Option valuation assumptions for options granted are as follows:

The risk‑free interest rate is based on the U.S. treasury security rate in effect as of the date of grant. AsBeginning in fiscal year 2021, the Company hasutilized historical realized volatility for expected volatility which is based on historical stock prices during a period of time. Prior to fiscal year 2021, the Company had little history with respect to volatility of share prices, and as such, the expected volatility iswas not based on realized volatility. The Company, as permitted under ASC 718, hashad identified guideline public companies who are participants in the Company’s markets. The Company obtained share price trading data from the guideline companies and based their estimate of expected volatility on the implied volatility of the guideline companies in addition to the Company’s own implied volatility. As the guideline companies arewere comparable in most significant respects, the Company believesbelieved they represent an appropriate basis for estimating expected volatility.
The Company estimated the fair value of PSUs on the grant date using a Monte Carlo Simulation incorporating the assumptions noted in the following table.

The Company does perform ongoing credit evaluations of its customers and maintains an allowance for potential credit losses on trade receivables. As of and for the years ended September 30, 2019, 20182021, 2020 and 2017,2019, no customer accounted for more than 10% of net sales or net accounts receivable.

23.24. Business Segments
The Company’s reportable operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated on a regular basis by the chief operating decision maker, or decision making group, in deciding how to allocate resources to an individual segment and in assessing performance. The key factors used to identify these reportable operating segments are the organization and alignment of the Company’s internal operations, the nature of the products and services, and customer type.
During the first quarter of 2019, theThe Company implemented changes to its organizational and management structure that resulted in changes to our reportable operating segments for financial reporting purposes. Through the fiscal year ended September 30, 2018, the Company had three reportable operating segments: Industrial, Municipal and Products. Changes in the management reporting structure during the first quarter of 2019 required an assessment to be conducted in accordance with ASC Topic 280, Segment Reporting, to determine the Company’s reportable operating segments.
As a result of this assessment, the Company now has two2 reportable operating segments, Integrated Solutions and Services and Applied Product Technologies. Prior period information has been revised to reflect this new segment structure. The business segments are described as follows:
Integrated Solutions and Services is a group entirely focused on engaging directly with end users through direct sales with a market vertical focus. Integrated Solutions and Services provides tailored services and solutions in collaboration with the customers backed by life‑cycle services including on‑demand water, outsourced water, recycle / reuse, and emergency response service alternatives to improve operational reliability, performance, and environmental compliance. Key offerings within this segment also include equipment systems for industrial needs (influent water, boiler feed water, ultrahigh purity, process water, wastewater treatment and recycle / reuse), full-scale outsourcing of operations and maintenance, and municipal services, including odor and corrosion control services.
Applied Product Technologies is focused on developing product platforms to be sold primarily through third party channels. This segment primarily engages in indirect sales through independent sales representatives, distributors, and aftermarket channels. Applied Product Technologies provides a range of highly differentiated and scalable products and technologies specified by global water treatment designers, OEMs, engineering firms, and integrators. Key offerings within this segment include filtration and separation, disinfection, wastewater solutions, anode and electrochlorination technology, and aquatics technologies and solutions for the global recreational and commercial pool market.


The Company evaluates its business segments’ operating results based on revenue, earnings before interest, taxes, depreciation and amortization, and certain other charges that are specific to the activities of the respective segments. Corporate activities include general corporate expenses, elimination of intersegment transactions, interest income and expense and certain other charges. Certain other charges include restructuring and other business transformation charges that have

Since the Company was in a net loss position for the year ended September 30, 2019, there was no difference between the number of shares used to calculate basic and diluted loss per share. Because of their anti-dilutive effect, 3,3561,784 and 2,512 common share equivalents, comprised of employee stock options, have been excluded from the diluted EPS calculation for the yearyears ended September 30, 2019.

Item 9A.    Controls and Procedures
Evaluation of Disclosure Controls and Procedures
In accordance with Exchange Act Rules 13a-15(e) and 15d-15(e), our management, under the supervision of our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Annual Report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2021.

The Company completed its acquisition of WCSI on April 1, 2021 and has not yet included WCSI in its assessment of the effectiveness of its internal control over financial reporting. The Company is currently integrating WCSI into its operations, compliance programs and internal control processes. Accordingly, pursuant to the SEC’s general guidance that an assessment of a recently acquired business may be omitted from the scope of an assessment in the year of acquisition, the scope of our assessment of the effectiveness of our disclosure controls and procedures does not include WCSI. WCSI constituted approximately 0.7% of the Company’s total assets as of September 30, 2021, and approximately 0.3% of the Company’s net sales for the fiscal year ended September 30, 2021.

Management’s Annual Report on Internal Control Over Financial Reporting
Management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, the company’s principal executive and principal financial officers and effected by the company’s board of directors, management, and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:
Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company;
Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and
Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
The Company completed its acquisition of WCSI on April 1, 2021 and has not yet included WCSI in its assessment of the effectiveness of its internal control over financial reporting. The Company is currently integrating WCSI into its operations, compliance programs and internal control processes. Accordingly, pursuant to the SEC’s general guidance that an assessment of a recently acquired business may be omitted from the scope of an assessment in the year of acquisition, the scope of our assessment of the effectiveness of our disclosure controls and procedures does not include WCSI. WCSI constituted approximately 0.7% of the Company’s total assets as of September 30, 2021, and approximately 0.3% of the Company’s net sales for the fiscal year ended September 30, 2021.
