Part I

Item 1. Business
Company Overview
Evoqua Water Technologies Corp. (referred to herein as “the Company,” “Evoqua,” “we,” “us,” or “our”) was incorporated on October 7, 2013. On January 15, 2014, Evoqua acquired the Water Technologies business unit formerly owned by Siemens AG (“Siemens”). On November 6, 2017, we completed our initial public offering (“IPO”), and our common stock 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 is 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 water is used it is considered effluent water, and we 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 spring 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 950 employees in field service and application engineering roles.
8


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 comprehensive municipal representative network in the U.S., providing us with an opportunity to influence specifications and the basis of design for 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 supply 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 supply of clean 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 year ended September 30, 2021, we deployed a more robust strategic pricing program to focus on efficient and effective price increase implementation with the objective 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 cost 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 our 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 capacity to support our planned growth without commensurate increases in fixed costs.

Continue to expand our capabilities for the treatment 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 extensive service branch network, located predominantly in the United States, as well as a large fleet of mobile assets to 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 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 our service capabilities in the Houston 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 the 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
12


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 pandemic 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 EPC that we have commissioned to build 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 limited 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 vendors and from our facilities to our customers, as well as for direct shipments from vendors to customers. Factors beyond our control, many of which have been caused or exacerbated by the 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 able to 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 potential 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.
Our 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 lines 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 timely 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.

17


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 projects and 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 negative 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 treatment 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, purchasing, 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 any 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 concentration 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 (“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, the Netherlands, Germany, Australia, China, Singapore, India, and Korea, including 11 manufacturing facilities, 7 research and 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 cooperating 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.
Unregistered Sales of Equity Securities and Use of Proceeds

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 of Financial 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 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.
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 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.
For the years ended September 30, 2021 and 2020, our segments accounted for the following percentage of our revenue:
20212020
Integrated Solutions and Services segment65.5 %66.1 %
Applied Product Technologies segment34.5 %33.9 %
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.

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) 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.

$1,464.4 100.0 %$1,429.5 100.0 %$34.9 2.4 %
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 lesser extent, capital revenue in the chemical processing industry in the second half of the fiscal year. In addition, organic revenue was favorably impacted by higher sales volume in service 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 comprised of the following:
Year Ended September 30,

(In millions)% of Revenue% of Revenue% Variance
General and administrative expense$(206.5)(14.1)%$(192.6)(13.5)%7.2 %

Research and development expense(13.4)(0.9)%(13.2)(0.9)%1.5 %
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 foreign currency translation gains of $7.7 million from the prior period which is mostly related to intercompany loans, increased amortization expense due to acquisitions in the current period, 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.
Interest 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 our 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 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.
