Who We Are \e-vōk-wä\

Evoqua is a leading provider of mission-critical water and wastewater treatment solutions, offering a broad portfolio of products, services, and expertise to support customers acrossfor various end markets. The Company is organizationally structured into two reportable operating segments for the purpose of making operational decisions and assessing financial performance: (i) Integrated Solutions and Services and (ii) Applied Product Technologies. We are headquartered in Pittsburgh, Pennsylvania, with locations across tennine countries. We have a comprehensive portfolio of differentiated, proprietary technologies offered under market-leading and well-established brands.

Our business iskey end markets are highly diversified with many end markets:

Understanding the Complete Water Cycle. 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.global:

Building Sustainable Water Systems. Our core treatment solutions include water clarification, separation, filtration, adsorption, disinfection, and solids removal, which remove impurities from water, rather than neutralizing them through the addition of chemicals. We also have an expanding portfolio of digitally connected and enabled solutions designed to help our customers achieve lower costs through greater uptime, throughput, and efficiency in their operations, while supporting their regulatory compliance and environmental sustainability efforts. Coupled with our extensive network of service branches, which means a certified Evoqua Service Technician is within approximately a two-hour drive from 90% of our industrial North American customers’ sites, and our rapid-response fleet of mobile water treatment systems, we believe we are uniquely positioned to implement tailored solutions and provide critical ongoing service and support to our customers.

We became a publicly traded company when our common stock began trading on the New York Stock Exchange (“NYSE”) on November 2, 2017, under the ticker symbol “AQUA.”

Financial Performance HighlightsOur Director Nominees and Continuing Directors

Strong Positioning for GrowthOur Board of Directors provides oversight, strategic direction, and counsel to management regarding the business, affairs, and long-term interests of our Company and our stockholders. An overview of our Class II director nominees and continuing Board members, as of the date of this Proxy Statement, is provided in the table below.

Historically Stable and Recurring Revenues

The chart below shows our revenue and organic revenue⁽¹⁾ performance from fiscal year 2018 through fiscal year 2021. Our pipeline remains robust as demand is strong across almost all of our end markets. Our goal is to achieve annual organic revenue growth of 3% to 5% over the next several years. Prior to the COVID-19 pandemic, we grew organic revenues within this targeted range. Over the past two fiscal years, we have navigated the COVID-19 pandemic and maintained stable revenues while growing organic revenues by 1.6% each year, which we believe showcases the resilience of our recurring revenue model, the diversity and breadth of our customer end markets, and the competitiveness of our highly differentiated products and services.

For additional information about our Board governance practices, see “Corporate Governance — Board Operations” in this Proxy Statement.

Our Approach to Planet and People

Natural Capital.Management of Water Resources. We are proud to have a product portfolio with a 100-year heritage of innovative water innovationsand wastewater treatment solutions that ensurepromote health and safety, enable customer performance, and create sustainable environments.help protect the environment. We are continuously building on this experience to identify water issues on the horizon and develop solutions to help our customers stay ahead and meet their sustainability goals. Highlighted below are some of the ways we are creating opportunities for better water stewardship.

• •  Digital Water.Water. We bring innovation to the water industry through our digitally connected solutions. These solutions leverage our water expertise and industry-leading branch network to deliver a differentiated level of service. Our Water One® services platform is a digital water management solution that combines our water expertise, proactive service, industry-leading branch network, proven technology, and data intelligence to optimize water purification processes. Thisbased on remote monitoring technology that drives efficiencies in operations and service. We are continuing to accelerate our digital business transformation journey. In September 2022, we launched a new offering, Sophis™ Digital Services: A Water One® Services Solution. Sophis™ Digital Services uses digital intelligence and continual learning to generate analyses of process and operational data, which can be used to mitigate risks and optimize system operations, troubleshooting, and design. Digitally Connected Solutions Reduce Operational Risk Our new solution, has enabled many laboratoriesSophis™ Digital Services, mitigates operational risk: •  Predicts and sanitization product manufacturers to anticipate prevents process anomalies before they occur •  Reduces life cycle costs by optimizing system performance and prepare for sudden changes in theirmaintenance •  Helps manage water usage resulting from increased demand for their servicesuse, energy efficiency, and products during the COVID-19 pandemic.waste Recycle/Reuse.Reuse. As human population growth has increased the demand for water, industrial plants are investigating alternative water sources and sustainable water solutions in order to decrease costs, reduce the size of their facilities’ water footprint, and be conscientious members of a community. We provide insight and clarity on where to focus water recycling and reuse efforts and implement the right treatment and reuse solution. With our broad range of proven technologies and extensive application expertise, we can develop tailored solutions across diverse end markets, regardless of water quality requirements, space constraints, and budgetary considerations. Human Capital and Inclusion and Diversity. We believe our talent within the organization is key to our long-term success. To succeed as a water technology company, we need to be able to optimize a myriad of processes and operations of industrial, commercial, recreational, and municipal customers across a wide spectrum of end markets; distribute and sell highly differentiated products and technologies through multiple sales channels around the world; and continually develop or acquire new products, services, and solutions. As a global, complex organization, we rely on talented individuals at every level to deliver on our core value proposition to our customers and other stakeholders. We focus on creating a high performance culture in which our employees are highly enabled, empowered, and accountable to deliver results. We continually work on programs to foster leadership development, enhance the overall employee experience, and leverage technology and process improvements to enable our employees to perform more effectively. Below are some examples of steps we are taking under our inclusion and diversity strategy:   Forming the Evoqua Inclusion Network, a business resource group that is tasked with identifying opportunities to promote greater inclusiveness and minimize unconscious bias. Establishing an unconscious bias learning program for all global employees. Striving to sustain higher levels of participation by women in the Company’s Leadership Development Program (“LDP”), a 24-month long recruitment program in which new university graduates participate in cross-functional rotations intended to develop their capabilities through organization-wide exposure. Over the past three years, women have represented, on average, 52% of our LDP participants. In 2021, women constituted 45% of our LDP participants. Requiring interview panels for senior leadership roles to include diverse personnel. Implementing other recruiting strategies, including branding and advertising within the talent market, to attract diverse candidates.   4 SAFETY AT EVOQUA 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 (“EHS”) 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. Since the beginning of 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. Our Sustainability Program In 2020, we adopted “sustainable” as our fourth core value, to celebrate the sense of stewardship we strive to imprint throughout our business:   Human Capital. In fiscal year 2022, we implemented a number of enhancements to our existing human resources programs, to further our philosophy and vision for a high-performance culture in which employees are enabled, empowered, and accountable to deliver results. Our enhancements focus on safety, professional development, inclusion & diversity (“I&D”), health, wellbeing, and flexibility, recognition, and purpose, based on feedback collected from employees and prospective employees. A summary of some of our enhancements is below.   •  Zero-Incident Safety Culture. We launched new training strategies and technologies to help our leaders and manufacturing and field service employees foster a more effective zero-incident safety culture.      OUR HANDPRINTWe Used Employee Feedback to Enabling our customers to become more sustainable through our solutions and service offerings    OUR FOOTPRINT Evoqua’s responsibility to become more sustainableDevelop Priorities in our internal operations Our Sustainability Program. In addition to helping our customers improve their sustainability performance, we are working to lessen the environmental impact of our internal operations; help our employees, supply chain partners, and communities thrive; and improve the communities in which we work. Our sustainability program is operated by a cross-functional team consisting of a core sustainability team and senior leaders from operations, EHS, supply chain, human resources, and legal. The core sustainability team reports to our Chief Growth and Sustainability Officer, and receives regular input from an internal Sustainability Steering Committee which monitors our various stakeholders’ interests.These Areas: Progress on Our ESG and Sustainability Journey. During 2021, we demonstrated our commitment to making further progress on our sustainability journey by delivering on the following: • In April 2021, we published our 2020 sustainability report, leveraging the reporting standards of the Global Reporting Initiative (GRI) to communicate more effectively with stakeholders on topics such as the Company’s approach to governance, human capital management, and health and safety.   •  We incorporated environmental, social, and governance (“ESG”)-related performance metrics in our fiscal year 2022 annual incentive program (“AIP”). A total of 10% of the aggregate bonus opportunity for our executives and senior managers is linked to meeting water stewardship and safety goals, both key elements of our company culture.Safety   •  Our Board amended the charters of the Compensation Committee and the Nominating and Corporate Governance Committee to formally delegate oversight of environmental and social matters to these committees.Professional Development   •  We expanded our internal sustainability organization, and formally designated Snehal A.

To foster a successful employee experience in this new environment, we held workshops to educate our managers on our flexible work arrangements program to support them in helping our employees work effectively, held on-site events to enhance employees’ sense of connection in a hybrid work environment, and are piloting new ways to offer flexible work schedules for on-site roles at our production facilities. We expanded employee benefits offerings, financial education webinars and coaching, and our approachemployee assistance program, which offers confidential help for a wide array of concerns such as relationships, family issues, general stress, personal loss, financial hardship, and parenting.

See pages 67-69 of this Proxy Statement for more information. Financial Performance Highlights We executed well in fiscal year 2022 and produced another year of strong financial results. We believe our financial results demonstrate how our business strategy and focused execution are creating enterprise value and long-term growth. ObjectiveThe Company achieved broad-based growth and double-digit improvements across revenue, net income, and certain other key financial performance metrics that we use to measure our enterprise growth. We increased net income by 39.8% to $72.3 million and adjusted EBITDA(2) by 18.7% to $297.7 million.   We also continued to prioritize cash generation to maintain our resiliency and capacity to execute on growth opportunities or other beneficial actions, such as repayment of debt. We achieved strong operating cash flow results, improving to $181.4 million in FY’22 versus $178.7 million in FY’21. We remain focused on driving profitable growth and continuing to strengthen our balance sheet through consistent generation of strong cash flow. Anchored by our large concentration of business in North America and our diverse end markets, we seek to generate stable, recurring, and predictable revenues and strong cash generation while pursuing multiple organic revenue growth and margin expansion initiatives, as well as accretive inorganic opportunities. (1)  For more information, see “Appendix B — Revenue Growth by Driver.” (2)For more information, see “Appendix A — Non-GAAP Financial Measures — GAAP Reconciliations.”    Summary of ChangeWe generated 18.6% revenue growth compared to FY’21. Organic revenue(1) contributed $149.4 million, or 10.2%, to revenue growth, as we delivered favorable price realization and higher volume for both products and services across most product lines and all regions. Inorganic revenue(1), primarily from acquisitions, contributed $137.1 million to our FY’22 revenue growth. Foreign currency translation impacted revenue growth by $(13.8) million.(1)   Link Short-Term Incentives to ESG Goals    10% of the AIP opportunity under our fiscal year 2022 AIP will be tied to two new ESG-related performance metrics. These metrics are based on two of the defining elements of the Company’s culture—water stewardship and safety.   Performance metrics:We have completed 20 acquisitions since 2016, which allow us to:   •  Water Stewardship: Based on achieving a target level of water reuse/recycling vs. water withdrawn from source at Evoqua’s ten most water-intensive facilities (5%)Enhance our technology portfolio;   •  Safety: Based on Total Recordable Incident Rate (TRIR), as calculatedIncrease our critical mass in accordance with OSHA requirements (5%) Link Long-Term Incentives to Financial Performance Goals Performance share units replaced the stock options under our fiscal year 2022 LTIP, resulting in an equity mix of 50% performance share units (at target) and 50% restricted stock units.

In the event the roles of Board Chairperson and CEO are combined, we require the appointment of a Lead Independent Director to help provide independent oversight of management. • 80% of our current Board members are independent; only our CEO and one director affiliated with our former private equity sponsor, AEA Investors LP, lack independence. • 100% of the members of the key committees of the Board (Audit, Compensation, and Nominating and Corporate Governance Committees) are independent. • Non-management directors meet in executive session without management present at nearly all Board meetings. • All current Audit Committee members meet the NYSE listing standard of financial literacy and two members are audit committee financial experts under Securities and Exchange Commission (“SEC”) rules.

Keating    President and Chief Executive Officer and Director Benedict J. Stas    Executive Vice President, Chief Financial Officer and Treasurer Rodney O. Aulick    Executive Vice President, Integrated Solutions and Services Segment President Hervé P. Fages    Executive Vice President, Applied Product Technologies Segment President Vincent Grieco    Executive Vice President, General Counsel and Secretary Our Approach to Executive Compensation Investing in our talent is critical to enabling us to deliver value to our customers and stockholders. To attract the leadership needed for our business to be successful, we strive to build a compelling, market-based, and flexible total compensation program that is strongly aligned with the interests of our stockholders and connected to key performance goals. We continued the evolution of our executive compensation program in fiscal year 2022. We introduced PSUs as an equity award vehicle, replacing the stock options that historically comprised 50% of our NEOs’ LTIP awards. The PSUs are linked to the achievement of financial performance goals relating to Average Adjusted EBITDA Margin (%) and Adjusted Cumulative Revenue Growth Dollars ($) over a three-year measurement period. To ensure our NEOs’ pay remains consistent with stockholder experience, the final amount of PSUs that will be earned and paid after the end of the three-year measurement period is subject to adjustment based on our TSR performance relative to the TSR of our performance peer group. We selected the companies listed in the S&P Global Water Index at the beginning of the measurement period as our TSR performance peer group. See “Executive Compensation — Compensation Discussion and Analysis — Long-Term Incentives” and “Appendix D — TSR Peer Group” for more information.       Aligning Pay with Stockholders’ Interests:   •  83% of CEO target compensation is variable.variable and “at risk,” being performance and/or stock-based.   •  41% - 66% of CEO target compensation and NEOan average of 48% of target compensation of our other NEOs is in the form of equity-based long-term incentives to provide strong alignment between executives’ and stockholders’ interests.   •  We strive to set total direct compensation levels in(i.e., sum of base salary, target annual incentives, and LTIP target value) for our regular-cycle program at or nearNEOs within a reasonable range of the median oflevels for comparable positions in our peer group used for benchmarking purposes.   •  RiskTo mitigate financial risks associated with our compensation policies, we maintain the following risk mitigation measures include ourmeasures: market-competitive stock ownership guidelines; a robust clawback policy that allows us to recoup erroneously awarded incentive compensation if a material restatement of the Company’s financial statements occurs or if certain misconduct causes economic or reputational damage to the Company; and cappedcaps on payouts on allfor performance-based awards,awards.

Keating, an incumbent Class II director and Class II director nominee, was not considered independent because of his employment with the Company as our CEO.     Former     Directors: Judd A. Gregg and Brian R. Hoesterey served as Evoqua directors during a portion of fiscal year 2022. Mr. Gregg retired from our Board at the end of his term at our 2022 Annual Meeting of Stockholders, and Mr. Hoesterey resigned from our Board on December 31, 2021. Our Board affirmatively determined that Mr. Gregg was an independent director. Mr. Hoesterey was not considered to be independent because of his affiliation with AEA Investors LP, our former private equity sponsor.       Summary of Applicable Independence Standards   Under our Corporate Governance Guidelines and the NYSE corporate governance standards, a majority of the members of our Board are required to be independent directors. An individual director is considered to be independent if our Board affirmatively determines the director does not have a material relationship with Evoqua or any of its subsidiaries that would interfere with the director’s exercise of independent judgment. A director may not be considered independent if he or she has any relationship with Evoqua that is described in the following objective tests for independence in the NYSE corporate governance standards:   •  A director currently is employed by Evoqua, or was employed by Evoqua within the last three years;   •  A director’s immediate family member currently is an executive officer of Evoqua, or was an executive officer of Evoqua within the last three years;   •  A director or immediate family member received more than $120,000 in direct compensation from Evoqua, except for certain permitted payments (such as director and committee fees, pension, or other forms of deferred compensation), during any 12-month period within the last three years;   •  Certain employment relationships between a director or an immediate family member and Evoqua’s internal or external auditors;   •  A director or immediate family member is an executive officer of a company, or has within the last three years been an executive officer of a company, during the same time that an Evoqua executive officer served on that company’s compensation committee; or   •  A director is an employee or an immediate family member is an executive officer of a company that has made payments to, or received payments from, Evoqua for property or services in excess of the greater of $1 million or 2% of such other company’s consolidated gross revenues in any of the last three fiscal years.   In the event a director has a relationship with the Company that is relevant to his or her independence and is not addressed by the objective tests for independence set forth in the NYSE corporate governance standards, our Board would determine, considering all relevant facts and circumstances, whether such relationship is material to the director’s ability to exercise independent judgment as a member of our Board.   DIVERSITY OF BACKGROUND, SKILLS, AND EXPERIENCE In the process of searching for qualified persons to serve on the Board, the Board strives for the inclusion of diverse knowledge and viewpoints, and takes into account age, gender, race, ethnicity, sexual orientation, gender identity, and other personal characteristics.

As Evoqua has transitioned from a pre-IPO group of water technologies businesses to a public company with a restructured operating model in the present day—and as we look ahead to potential future transitions in Evoqua’s business and the world around us—our Board seeks to maintain appropriate resources of institutional knowledge and leadership continuity, as well as refreshment of perspectives, skills, and experience. Of our non-employee directors, the four directors with the longest tenures have served for approximately eight years; two directors have served for approximately four years, and two directors have served for two years or less. As of January 1, 2022, our average board tenure for non-employee directors is approximately 5.4 years. Following Mr. Gregg’s retirement, and assuming each of the Class I director nominees is elected at the Annual Meeting, the average tenure of the non-employee directors on our Board will be approximately 5.0 years.

OUR GOVERNANCE FRAMEWORK Corporate Governance Guidelines We have adopted the Evoqua Water Technologies Corp. Corporate Governance Guidelines (our “Corporate Governance Guidelines”) to promulgate principles for the governance of our Board, the highest governing body of our Company. The Nominating and Corporate Governance Committee of our Board periodicallyannually reviews our Corporate Governance Guidelines and, as applicable, makes recommendations to our Board regarding appropriate updates to promote the quality and effectiveness of the Board as a governing body and comply with applicable laws, regulations, and NYSE listing requirements.

Code of Ethics and Business Conduct Integrity is a core value at Evoqua. We have adopted an enterprise-wide Code of Ethics and Business Conduct, which applies to our directors, officers (including our principal executive officer, principal financial officer, and principal accounting officer), and employees. OurEvoqua’s Code of Ethics and Business Conduct provides aan enterprise-wide framework for conducting business in an ethical manner and sets forth our expectations on a number of topics, including conflicts of interest, safety, compliance with laws, use of our assets, and business ethics.

The Board does not have a policy on whether the roleroles of the Chairperson and the CEO should be separate or combined.       •  Board Chairperson and CEO are separate roles   •  Board Chairperson is an independent director   We currently separate the roles of the CEO and the Board Chairperson. The Board has been led by a non-employee Board Chairperson since Evoqua commenced operations in 2014. Martin J. Lamb, an independent director, served as our Board Chairperson from 2014 until May 2021. In May 2021, our Board elected Gary A. Cappeline, also an independent director, as the Board Chairperson. 2022 Proxy Statement 27 We believe a leadership structure with a separate CEO and Board Chairperson is appropriate for our Company at this time due to the differences between the two roles.time. The CEO is responsible for setting our strategic direction, providing day-to-day leadership, and managing our business. The Board Chairperson provides guidance to the CEO, chairs Board meetings, sets the agendas for Board meetings, and maintains the flow of information to Board members in advance of, and in between, Board meetings. Currently, separating these leadership roles allows our CEO to focus on developing and implementing business strategies and objectives and monitoring the day-to-day management and performance of our Company. The Board Chairperson, on the other hand, is able to provide independent oversight of our Company, serve as an independent liaison between our management and the members of our Board in providing feedback to our CEO, and focus on governance of our Board, including Board composition and the recruitment of new directors, Board meeting schedules and agenda-setting, and information flow and management reporting to the Board.

The Audit Committee or the General Counsel and the Corporate Controller, as the case may be, may approve only those related party transactions that they determine are on terms, taken as a whole, that are no less favorable to us than could be obtained in an arm’s-length transaction with an unrelated third party and that are not inconsistent with the best interests of the Company. In particular, the RPT Policy requires our Audit Committee or the General Counsel and the Corporate Controller, as the case may be, in considering whether to approve or ratify a related party transaction, to take into account, among other factors: (i) whether the transaction was undertaken in the ordinary course of business, (ii) whether the related party transaction was initiated by the Company or the related party, (iii) the availability of other sources for comparable products or services, whether the transaction with the related party is proposed to be, or was, entered into on terms no less favorable to the Company than terms that could have been reached with an unrelated third party, and the duration of the transaction, and the terms available to unrelated third parties and employees generally, (iv) the purpose of, and the potential benefits to the Company of, the related party transaction, (v) the impact on a director’s independence in the event that the related party is a director, director nominee, immediate family member of a director or director nominee, or an entity in which any such person has an interest or relationship, (vi) the approximate amount involved in the related party transaction, (vii) the related party’s interest in the related party transaction, and (viii) any other information regarding the related party transaction or the related party that would be material to investors in light of the circumstances of the particular transaction or would impair the independence of an independent director or present an improper conflict of interest for any director or executive officer. For the purposes of the RPT Policy, a “related party” is defined as: (i) any person who is or was (at any time since the beginning of the last completed fiscal year, even if such person does not presently serve in that role) an executive officer, director or nominee for director of the Company, or any immediate family member of such person, (ii) any person beneficially owning more than 5% of any class of the Company’s voting securities at the time of the occurrence of the transaction at issue, (iii) any affiliates of the Company, (iv) any entities for which investments in their equity securities would be required to be accounted for by the equity method by the investing entity, (v) any trusts for the benefit of employees, such as pension and profit-sharing trusts that are managed by or under the trusteeship of management, and (vi) all members of the Company’s Executive Leadership Team, Finance Leadership, Plant Controllers, Segment Leadership and any immediate family member of such persons.

The Compensation Committee reviews the compensation of our non-employee directors periodically (generally every other year) and recommends changes to the Board when it deems appropriate. In 2021, the Compensation Committee reviewed our non-employee director compensation program based on market analyses prepared by Meridian, the independent compensation consultant engaged by the Compensation Committee to advise on executive and non-employee director compensation matters. Meridian’s analyses examined the non-employee director compensation practices of the Company’s peer companies included in the same comparator group that the Compensation Committee uses to benchmark executive officer compensation (as set forth in the “Compensation Discussion and Analysis” section (the “CD&A”) in this Proxy Statement). Based on these market analyses and its review with Meridian of current Board and committee leadership duties, the Compensation Committee recommended that the Board (1) simplify the structure of the non-employee director compensation program and (2) increase certain retainer amounts, including for the Board Chairperson and the Nominating and Corporate Governance Committee chairperson, to fall within a reasonable range of the market median levels observed in the comparator group for similar roles. Upon the recommendation of the Compensation Committee, the Board approved the following modifications to the non-employee directors’ compensation program: Increasing the annual cash retainer from $70,000 to $85,000 and the value of the annual equity grant from $100,000 to $125,000; Eliminating the committee member annual retainers; Increasing the Board Chairperson fee from $60,000 to $100,000 annually; and Increasing the Nominating and Corporate Governance Committee chairperson fee from $10,000 to $15,000 annually. These updates became effective on January 1, 2022, as the non-employee directors’ compensation program operates on a calendar year basis. The table below describessets forth the components of the non-employee directors’ compensation program that were in effect during the relevant portions of fiscal year 2021. The forms and amounts2022.

Among other things, Meridian provided a market analysis of director compensation practices based on the same comparator group then used for benchmarking executive officer compensation. In August and November 2021, the Board adopted updates to the non-employee directors’ compensation program, based upon the Compensation Committee’s review of such program with assistance from Meridian.

This proposal, commonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to express their views on our overall compensation policies and procedures relating to the NEOs. As described in detail in the CD&A, the Compensation Committee oversees our compensation program and the compensation awarded to our executive officers, adopts changes to the program, and awards compensation as appropriate to reflect the Company’s circumstances and to promote the main objectives of the program. These objectives include:   attracting and retaining top-level, talented leaders who reflect our culture of high performance, growth, and accountability;   motivating our leaders to create long-term value for our stockholders; and   aligning pay to performance. We are asking you to indicate your support for our NEOs’ compensation as described in this Proxy Statement. We believe the information we have provided in this Proxy Statement demonstrates that our compensation program is designed appropriately and works to ensure that the interests of our executive officers, including our NEOs, are aligned with your interest in long-term value creation. Accordingly, our Board recommends that the Company’s stockholders vote “FOR” the following resolution to approve, on an advisory basis, the compensation of our NEOs: RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including in the CD&A,Compensation Discussion and Analysis, the compensation tables and related narrative disclosure, is hereby approved on an advisory basis. Although this vote is advisory and nonbinding, the Board of Directors and the Compensation Committee intend to consider the results of the vote, as well as other relevant factors, as we continue to evolve our executive compensation program. At theour 2019 annual meeting,Annual Meeting of Stockholders, stockholders voted to hold an advisory “say-on-pay” vote on an annual basis. Accordingly, the Company has determined to submit an advisory vote on our executive compensation program to our stockholders at each annual meeting (with the next one occurring in 2023)2024) until the Company seeks another advisory vote on the frequency of the advisory vote on executive compensation, which is anticipated to occur at theour 2025 annual meeting.Annual Meeting of Stockholders.       THE BOARD UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE APPROVAL, ON AN ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS          46 Letter from the Compensation Committee Dear Fellow Stockholders, The Compensation Committee is committed to ensuring that Evoqua has the right leadership team firmly in place for the long term and that our compensation programs appropriately balance business performance and accountability to build a stronger, sustainable and more valuable company. As Evoqua enters its fifth year as a public company, we continue to focus on innovation and profitable growth. Demonstrated Performance Results. Under the leadership of Ron Keating, our CEO, and his executive leadership team (ELT), Evoqua has executed on its strategic plans, successfully navigated the challenging conditions and risks posed by the COVID-19 pandemic, and is well-positioned for on-going growth. Certain of Evoqua’s performance highlights and accomplishments are: • Relative Total Shareholder Return (TSR) at the 82nd percentile, as compared to our compensation peer group, and the 84th percentile, as compared to the Russell 2000, over the most recent three fiscal year period; • Absolute Stock Price increased by 111.2% over the most recent three fiscal year period and Evoqua’s stock recently closed at $47.24 per share on December 27, 2021; and • Revenue Compound Annual Growth Rate of 5.0% for the most recent five fiscal year period comparing favorably to 3.9% for the compensation peer group. We believe this consistent performance and impressive track record demonstrate the effectiveness of our team and their transformation of Evoqua from a collection of water technologies businesses, to an integrated, established business positioned for future success and stockholder value creation. Securing Our Executive Leadership Team. Evoqua’s success has not gone unnoticed by the marketplace. The executive leadership team is widely viewed as top-notch and the Compensation Committee and independent members of the Board became aware that certain members of the ELT were being solicited in a tight market for executive talent. We determined it was necessary to take action to secure our ELT in order to continue Evoqua’s growth and execute on our strategic plans. As such, we authorized special one-time retention awards for Mr. Keating and the other ELT members that incentivize significant value creation over the long term. We reached out to our top 25 stockholders to discuss the special retention awards, and encourage you to review the more detailed description of these awards and the feedback from our stockholder outreach on pages 55-56 in the CD&A. Fiscal Year 2022 Performance Incentive Awards. To incentivize and motivate toward achievement of Evoqua’s financial and sustainability-related goals, our ELT recommended a change to the design of our annual and long-term incentive programs for fiscal year 2022 to incorporate specific and quantifiable financial and ESG goals. The Compensation Committee discussed these changes with both internal and external stakeholders, and strongly supported: The annual incentive program including ESG goals for water stewardship and safety; and PSUs incorporated into the regular-cycle long-term incentive program with payout tied to the achievement of Organic Revenue Growth Dollars and Average Adjusted EBITDA Margin goals over a cumulative three-year performance period, with a relative TSR modifier affecting ultimate payout. We provide more information regarding our fiscal year 2022 performance incentive programs on pages 67-69 in the CD&A. Evoqua has a firmly embedded pay-for-performance culture, which is explained in detail in the CD&A. We have designed our executive incentive programs to ensure responsible long-term financial, operational, and stock price performance for our stockholders.

Evoqua’s vision is to be the world’s first choice for water solutions. As we strive to be the most trustedWe provide a wide range of product brands and complete source ofadvanced water and wastewater treatment systems and technologies, as well as mobile emergency water supply solutions across industrial, commercial, and municipalservice contract options through our branch network. We target attractive global end markets we believe our ability to refinethat utilize and leverage our knowledge about our customers’treat water as a critical part of their operations andor production processes, will continue to be a differentiator. including the life sciences, light and general industry, power, microelectronics, chemical processing, food and beverage, municipal drinking water and wastewater, aquatics, refining, and marine end markets. Investing in our talent is critical to enabling us to deliver value to our customers and stockholders, and that guides our executive compensation philosophy: to build a compelling, market-based, and flexible total compensation program that is strongly aligned with the interests of our stockholders and connected to key performance goals. 2022 Compensation Program Highlights We believe this philosophy has helped us attract, engage,For fiscal year 2022, we implemented key enhancements to our executive compensation program to strengthen the connection between our executives’ incentive opportunities and motivate the leadership neededcertain important drivers of value creation for our organization and our stakeholders: Introduction of Regular-Cycle Performance Share Units The Compensation Committee introduced PSUs as one of the regular-cycle equity award vehicles for our NEOs. As a result, the 2022 LTIP equity mix consists of 50% time-based restricted stock units (“RSUs”) and 50% PSUs (at target). The PSUs replace the stock options that historically comprised 50% of our NEOs’ LTIP awards. The PSUs are linked to achievement of financial performance goals relating to Average Adjusted EBITDA Margin (%) and Adjusted Cumulative Revenue Growth Dollars ($) over a three-year measurement period, reflecting our Board’s and management’s focus on long-term, profitable growth and value creation. To ensure that our NEOs’ pay will remain consistent with stockholder experience, the final amount of PSUs that may be earned and paid after the end of the three-year measurement period is subject to adjustment by a relative TSR modifier. See “Long-Term Incentives” in this CD&A for more information. Introduction of ESG-Related Performance Goals The Compensation Committee also included nonfinancial performance measures that are important to the Company’s overall business in the Company’s annual incentive plan (“AIP”) for fiscal year 2022. An aggregate of 10% of the incentive opportunity under our fiscal year 2022 AIP is tied to be successful. Intwo ESG-related performance metrics, safety and water stewardship, which are important elements of the past eight years since our inception, Evoqua has continuously worked to build a sustainable business that can deliver increasedCompany’s culture and value proposition to its customers and stockholders.stakeholders.

We are investing across multiple organic revenue growth and margin expansion initiatives, as well as expected accretive inorganic opportunities. FiscalWe executed well in fiscal year 2021 was2022 and produced another year of strong financial performance for Evoqua. We continued an overall positive trajectory in our operating resultsresults. The Company achieved broad-based growth and double-digit improvements across revenue, net income, and certain other key financial performance fueled, in part, by the October 2018 reorganization of our operating model to a more streamlined two-segment structure that aligns more strategically with how our customers purchase products and services. We believe our operating results demonstratemetrics that we have focused on appropriateuse to measure our enterprise growth. We generated 18.6% revenue growth compared to fiscal year 2021. We also increased net income by 39.8% to $72.3 million and beneficial priorities for our organization; that we have established an effective operating platform for managing the macroeconomic challenges that have arisen from the COVID-19 pandemic, such as unpredictable and unprecedented labor shortages and supply chain disruptions; our strong positioning for continued growth as customer demand returns post-pandemic; and, importantly, that our overall business strategy continuesadjusted EBITDA(1) by 18.7% to be resilient and productive.$297.7 million.

Organic revenue(2) contributed $149.4 million, or 10.2%, to revenue growth, as we delivered favorable price realization and higher volume for both products and services across most product lines and all regions. To complement our organic growth initiatives, we continued to execute on our M&A growth strategy, notably through our $195.0 million acquisition of the Mar Cor renal business previously operated by Steris plc, which we expect will accelerate our growth and scale in the Life Sciences end market. Inorganic revenue,(2) primarily attributable to the Mar Cor acquisition, contributed $137.1 million to our 2022 revenue growth. Additionally, foreign currency translation impacted revenue growth by $(13.8) million which resulted from the Company’s divestiture of the Memcor® product line in the first quarter of fiscal year 2020. ** Adjusted EBITDA and Adjusted Free Cash Flow are non-GAAP financial measures.

We believe this affirms our overall compensation strategy and how it supports our long-term business goals and our stockholders’ interests. The Compensation Committee will continue to consider stockholder input, including the say-on-pay advisory vote, as it evaluates the design of executive compensation programs and specific compensation decisions for executive officers in the future. The Compensation Committee reviews say-on-pay voting outcomes following our annual meeting and as it commences the decision-making process for the next fiscal year’s compensation program. Compensation Philosophy The goal of our executive compensation program is to attract and retain talent from our industry that have the greatest ability and potential to execute on the Company’s short-term and long-term business goals, creating profitable growth and durable, long-term stockholder value. Our program is guided by the following principles: Pay for Performance A significant portion of each NEO’s total compensation should be at-risk and performance-based with metrics aligned to the Company’s short-term and long-term financial performance and business strategy, reflecting the Company’s culture of high performance, accountability, and growth. Stockholder Alignment NEOs should be compensated through pay elements that align directly with the long-term interests of our stockholders and cultivate the NEOs’ ownership of, and accountability for, the Company’s vision and strategic direction. Attraction and Retention The executive compensation program should provide overall target compensation that is market-competitive and enables the Company to attract and retain high-caliber talent. Simplified Approach The executive compensation program should foster growth and motivation through a straightforward, flexible, and clear approach to compensation design. 2023 Proxy Statement 45         WHAT WE DO                    Pay for Performance Approximately 63-83%A significant portion of our executives’ compensation is variable compensationat-risk based on Company performance: both cash and equity incentives are performance-based.       Robust Stock Ownership Guidelines We have stock ownership guidelines for executive officers to instill pride in, and a sense of, Company ownership, and to align theexecutives’ interests of management andwith our stockholders.    Annual “Say-on-Pay” Vote We seek an annual non-binding advisory vote from our stockholders to approve the compensation paid to our NEOs as disclosed in our proxy statement.       Independent Compensation Consultant The Compensation Committee retains an independent compensation consultant and reassesses the consultant’s independence annually.    Encourage Long-Term OutlookESG-Related Performance Metrics Long-term awards have three- or four-year vesting periods.Our fiscal year 2022 AIP includes a water stewardship performance metric and a safety performance metric to drive the achievement of ESG-related performance goals and further align executive compensation with stakeholder interests.       BalancedDiversified Short-Term and Long-Term Incentives We establish clear, measurable, and appropriately rigorous performance goals and targets that are tied to key financial and operating performance goals, and cap the maximum payouts under our short-term and long-term incentive plan.plans.    Double Trigger Vesting Acceleration Awards under our current equity incentive plan generally allow vesting upon a change in control only if the award recipient is terminated without cause or for good reason within a specified time period following the change in control.       Clawback Policy We adopted a robust clawback policy that allows the Company to recoup incentive compensation earned by executive officers or other employees in the event of a material restatement of the Company’s financial statements or certain misconduct that has caused economic or reputational damage to the Company.    Minimum Vesting Requirement Awards granted under our current equity incentive plan generally are subject to a one-year minimum vesting requirement, with limited exceptions.       Multi-Dimensional Performance Assessments Performance assessments under our incentive plans are multi-dimensional and encompass the Company’s cash flow statement, earnings statement, and the market performance of our stock.           WHAT WE DON’T DO                    Hedging/Pledging of Company Stock We prohibit our officers and directors from hedging, margining, pledging, short-selling, or publicly trading options in our stock.       Excessive Perquisites We do not provide reimbursement to our NEOs for any perquisites beyond a prescribed limited cap applicable to anthe executive.    Dividends on Unvested Equity Awards We do not pay dividends on unvested equity awards, including options, restricted stock, and performance shares.       Repricing or Exchange of Underwater Options We prohibit option repricing without stockholder approval.    Change in Control Excise Tax Gross-ups We do not pay excise tax gross-ups on change in control payments.       Single Trigger Vesting Acceleration No awards granted under our current equity incentive plan will vest solely because of a change in control of the Company.        2022 Proxy Statement      46    51   HighlightsOverview of Our Fiscal Year 2021 Executivethe Compensation ProgramDetermination Process Each year, the Compensation Committee works according to an established schedule to determine the appropriate mix and level of pay elements for the next fiscal year.   Our Approach and Factors ConsideredAugust 2021   Resulting Determinations   (1)  The full Board reviews the Company’s long-term strategic plan and the annual operating plan and budget for the next fiscal year (2022).

Factors and Considerations The Compensation Committee generally strives to provide each NEO with compensation that is within a reasonable range of the market median levels for comparable positions in the comparator group and published compensation surveys that the Compensation Committee uses for compensation benchmarking purposes. The Compensation Committee considers such market data for base salaries, total cash compensation (i.e., base salary plus target annual incentives), and total direct compensation (i.e., base salary plus target annual incentives and target long-term incentives) of our NEOs. The Compensation Committee also considers other relevant information in the compensation-setting process, such as the current level of the executive’s compensation (individually and relative to other executives); the length of tenure, level of experience, performance, and responsibilities of the individual executive; Company performance in the most recently completed fiscal year; and the recommendations of our CEO. The CEO does not participate in deliberations to determine his compensation. The Compensation Committee makes compensation decisions for our CEO in executive session, without our CEO present. • ISS Segment Adjusted EBITDA performance at 98.6% of targetFor more information—   •  ResultedAbout market data referenced by the Compensation Committee, see “—Peer Group and Benchmarking” in overall payout at 106.0% of target bonus opportunity for Mr. Aulick • APT Segment contributed to increased sales volume across multiple product lines and all regions globally, supported by disciplined price/cost and product portfolio management • APT Segment Adjusted EBITDA performance at 106.5% of targetthis CD&A.   •  ResultedAbout the Compensation Committee, including the roles of its independent compensation consultant and management in overall payout at 126.2%the compensation-setting process, see “Corporate Governance—Standing Board Committees—Role of target bonus opportunity for Mr. Fagesthe Compensation Committee” in this Proxy Statement.        52 Our Approach and Factors Considered Resulting Determinations • Maintain balanced incentives in fiscal year 2021 • Balanced incentives are created by our equity mix of 50% restricted stock units (“RSUs”) and 50% stock options: RSUs support stock price alignment and retention by enabling award recipients to receive Company stock if they are still employed by us on the date the restrictions lapse; and stock options encourage strong alignment with stockholders’ interest in the market value growth of our Company.

To this end, our program is guided by the following principles: Pay for Performance A significant portion of each NEO’s total compensation should be at-risk and performance-based with metrics aligned to the Company’s short-term and long-term financial results and business strategy, reflecting the Company’s high-performance culture, accountability, and high-growth trajectory. Stockholder Alignment NEOs should be compensated through pay elements designed to align directly with the long-term interests of our stockholders, and our executives should share with our stockholders in the performance and value of the Company, cultivating ownership of the Company’s vision and strategic direction. Attraction and Retention The executive compensation program should provide overall target compensation that is market-competitive and enables the Company to attract and retain high-caliber talent. Simplified Approach The executive compensation program should foster growth and motivation through a straightforward, flexible, and clear approach to compensation design. Core Objectives Instill a sense of ownership and pride in Evoqua in order to drive excellence Create market-competitive compensation opportunities to attract and retain executives who reflect our culture of high performance, growth, and accountability Support overall alignment of pay and performance, while considering retention of key talent Promote the values of teamwork and respect Oversight by the Compensation Committee The Compensation Committee is responsible for oversight of the executive compensation arrangements for our executive officers, including our NEOs, and exercises these duties with the overall intent of structuring future compensation in a way that provides fair and reasonable compensation to our executive officers based on their performance and contributions to the Company; keeps their focus on long-term Company growth; instills in them a long-term commitment to the Company; and aligns their interests with the interests of our stockholders. To ensure our executive compensation program remains flexible, the Compensation Committee may exercise its discretion to adjust compensation to meet business needs and preserve a clear connection between compensation and performance. The Compensation Committee has the authority to approve, adopt, administer, interpret, amend, suspend, and terminate compensation plans applicable to our executive officers, and meets throughout the year to assess, revise as appropriate, and ultimately determine, the compensation packages for our executive officers. At the request of the Compensation Committee, these meetings are also attended by the Chief Executive Officer, the Chief Human Resources Officer, and representatives of the Compensation Committee’s independent compensation consultant. Prior Year Say-on-Pay Vote Following our 2021 Annual Meeting of Stockholders, the Compensation Committee reviewed the results of the stockholder advisory vote, or “say-on-pay” vote, that was held at the 2021 Annual Meeting with respect to the 54 compensation of our NEOs for the 2020 fiscal year. Approximately 93% of the shares of common stock present in person or represented by proxy at the 2021 Annual Meeting and entitled to vote were voted in support of the compensation of our NEOs, and we believe this affirms the steps we are taking to align our NEOs’ compensation with our stockholders’ interests. The Compensation Committee will continue to consider stockholder input, including the advisory say-on-pay vote, as it evaluates the design of executive compensation programs and specific compensation decisions for executive officers in the future. Stockholder Engagement We actively engage with our stockholders and stakeholders in a number of forums on a year-round basis. These efforts supplement the ongoing communications between our management and stockholders through various engagement channels, including direct meetings, analyst conferences, and roadshows. We take feedback and insights from our engagement with stockholders and other stakeholders into consideration as we review and evolve our practices and disclosures. As part of these engagement efforts, we proactively reached out to our stockholders to discuss the rationale of our Compensation Committee for the Special Awards that were granted to the NEOs and other executive officers in May 2021, as described on pages 64-67 of this CD&A. In the summer and fall of 2021, Gary Cappeline, Chairperson of our Board and the Compensation Committee, and Dan Brailer, Director of Investor Relations, reached out to our largest stockholders representing approximately 66% of our outstanding shares at that time. Stockholders representing approximately 18% of our outstanding shares agreed to engage with us. These engagement conversations generally focused on our executive compensation program and the Special Awards. We also invited stockholders to ask questions and provide us with feedback on other ESG matters. A summary of our engagement with stockholders on those topics is provided on page 39 of this Proxy Statement. Below is a summary of the feedback we received from our stockholders on executive compensation-related matters: Special Awards • Most stockholders indicated that our rationale for granting the Special Awards was well-explained and understandable, particularly in light of the tight market for executive talent, and appreciated several aspects of the Special Awards that are aligned with stockholders’ long-term interests, such as (a) the use of a relative TSR performance metric with vesting at threshold when Evoqua’s stock is at the 60th percentile relative to the peer group, and (b) capping payout at target when Evoqua’s stock is at the 80th percentile or above, relative to the peer group. Stockholders also appreciated that the full target payout will require outstanding relative TSR performance. • Some stockholders asked questions related to the structure of the award and retention. We provide information about the structure of the Special Awards on pages 64-67 of this CD&A. Executive Compensation Program • Stockholders appreciated that we have taken steps to include financial and TSR performance metrics in our regular-cycle long-term incentive program for fiscal year 2022, as discussed on pages 68-69 of this CD&A. • Some stockholders asked whether we considered incorporating ESG-related metrics into our compensation program. Subsequently, the Compensation Committee considered this feedback in determining the performance metrics for the fiscal year 2022 AIP. See pages 67-68 of this CD&A for more information about the ESG-related performance metrics we are incorporating in our AIP for fiscal year 2022. 2022 Proxy Statement 55 Messrs. Cappeline and Brailer shared the feedback received from these engagements with the Board and the Compensation Committee. The Compensation Committee considered this stockholder input, along with market practices, standards, and policies, in reviewing the Company’s executive compensation program and developing the fiscal year 2022 programs. Role of the Independent Compensation Consultant The Compensation Committee obtains advice from an independent compensation consultant on all matters related to compensation design decisions for our executive officers. For fiscal year 2021, the Compensation Committee continued the engagement of Meridian as its independent compensation consultant. Meridian provides the Compensation Committee with relevant market data, current updates regarding trends in executive compensation, and advice with respect to program design. Meridian also provides specific compensation recommendations for the CEO and feedback on compensation recommendations made by the CEO for executives other than the CEO. Representatives of Meridian attended all meetings of the Compensation Committee in fiscal year 2021. Fiscal Year 2021 Peer GroupBenchmarking Throughout the compensation setting process, the Compensation Committee solicited information from its independent compensation consultant, Meridian, about compensation practices across a group of peer companies used as a general comparator group for benchmarking purposes.purposes for comparable positions.

The Compensation Committee determines its comparator group annually, before commencing work on the executive compensation program for the new fiscal year. With assistance from Meridian, the Compensation Committee assesses the adequacy of the comparator group used for the prior fiscal year, and makes adjustments as appropriate. The Compensation Committeeutilizes general industry and comparator group data that is intended to be representative of the market in which we compete most directly for executive talent, and seeks to set pay at or within a reasonable range of the market median.   The principal selection criteria for the comparator group were developed by Meridian after obtaining management’s views on the Company’s competitors for executive talent and consideration of other relevant factors; thefactors. The Compensation Committee believes there are no public companies that provide the full scope of water and wastewater treatment products, solutions, and services that the Company offers.   In August 2020,2021, the Compensation Committee, in consultation with Meridian, determined that the peer selection criteria and group size used infor fiscal year 20202021 compensation decisions remained appropriate.

In addition, based on its consultations with Meridian, the Compensation Committee determined it would be beneficial and consistent with the peer selection criteria to add Harsco CorporationPentair plc and EnPro Industries, Inc.Crane Holdings, Co. to the comparator group for fiscal year 2021. Milacron Holdings, Corp.2022. Forterra, Inc. was removed from the comparator group due to its pending acquisition by Hillenbrand,Quikrete Holdings, Inc. in November 2019.   In addition to the comparator group, the Compensation Committee uses information regarding compensation practices across a broader survey of manufacturing companies to provide greater context for the comparator group information and to benchmark roles for which peer group data may not be as directly applicable.       Comparator Group—Principal Selection Criteria and Considerations   •  The comparator group consists of publicly traded companies, designatedselected according to the below selection criteria and factors:   •  Reflect the Company’s business competitors and have a similar business strategy;   •  Represent the most appropriate peers that are industry-relevant competitors of the Company for the same executive talent; and   •  Generated revenues for the trailing twelve months ranging from approximately 33% to 300% of the Company’s revenues.   •  The size and composition of the comparator group should allow for more robust sampling across all executive positions; ensure allconsist of peer companies that have industry relevance; and ensureprovide an appropriate range with respect to the size of peers.   •  The comparator group should be constructed so as to position the Company within a reasonable range of the median of the peer companies.          20222023 Proxy Statement           5749   Fiscal Year 2021 Compensation Determination Process Each year, the Compensation Committee works according to an established schedule to determine the appropriate mix and level of pay elements for the next fiscal year. August 2020 (1)   The full Board reviews the Company’s long-term strategic plan and the annual operating plan and budget for the next fiscal year. (2) The Compensation Committee, with assistance from Meridian, members of senior management, and other advisors, then reviews the existing incentive plans and discusses any appropriate design adjustments to be implemented for the next fiscal year. (3) After the end of the current fiscal year, the Compensation Committee reviews the year-end financial results and determines the level of achievement reached under the annual incentive plan and the payout amounts, if any. (4)  The Compensation Committee evaluates CEO performance and, with input from the CEO, the performance of the other NEOs for the most recently completed fiscal year. The Compensation Committee also reviews competitive market pay levels.

(3) Beginning with our fiscal year 2022 compensation program, PSUs replaced stock options as a long-term incentive award vehicle. See “Long-Term Incentives” in this CD&A for further details on this change and the applicable performance criteria for the PSU awards.                 5850        Compensation “At-Risk” Incentive Compensation A significant portion of our NEOs’ target total direct compensation (i.e., fixed salary and annual and long-term incentive awards) consists of incentive compensation that is at risk and influenced by Company performance and/or share price. We believe this strongly aligns the interests of our NEOs with those of our stockholders. The Compensation Committee sets the target annual incentive amount as a percentage of each NEO’s salary, while the target long-term incentive amount is set as an absolute dollar amount. In 2022, 83% of Mr. Keating’s target total direct compensation was at risk. For the remaining NEOs, an average of 68% of their aggregate target total direct compensation was at risk. The compensation components that are “at risk,” or contingent upon Company performance and/or share price, are illustrated in the charts below.   Component Time Horizon Objective Form of Compensation   Long-Term Incentives 4 years •  Variable compensation that is tied to the Company’s long-term growth. •  Purpose is to drive long-term stockholder value creation, promote strong alignment between stockholders and executives, and support the Company’s retention strategy. •  In fiscal year 2022, performance share units will replace stock options. 50% stock options, which vest in equal annual installments over a four-year period with a ten-year term. 50% RSUs, which vest in equal annual installments over a four-year period and are settled in stock. The Compensation Committee does not maintain any formal policy or formula for allocating the mix of pay elements in the executive compensation program, as it believes it is more important to remain flexible to respond to business needs and shifts in the marketplace in which the Company must compete to recruit and retain executive talent. Therefore, the Compensation Committee retains the authority to review our NEOs’ total compensation periodically and to use its discretion to adjust the mix of compensation and the amount of any element of compensationpay elements as it deems appropriate for each NEO.

The Compensation Committee considers, among other factors, market data, the level of the executive’s compensation (individually and relative to other executives), the length of the executive’s tenure, the level of the executive’s performance and, for the base salaries of executives other than our CEO, the recommendations of our CEO. The Compensation Committee also may authorize periodica base salary adjustmentsadjustment outside of its customary annual review in connection with a NEO’s promotion or change in job responsibility or when otherwise necessary for equitable reasons. Base salaries typically are set near the median salary levels for comparable positions in the peer group used for benchmarking purposes. Based on its annual evaluation, in December 2020, and after giving consideration to the continuing COVID-19 pandemic and related macroeconomic uncertainties, the Compensation Committee determined not to increase our NEOs’ base salaries for the calendar year 2021.

Payout amountsCEO and other NEOs. Target Short-Term Incentive Opportunity Each NEO has a target annual incentive opportunity under the AIP, are based on achievement of predetermined Company-wide annual goals and, for the Segment presidents, Messrs. Aulick and Fages, predetermined Segment-based annual goals. Target Bonus Opportunity Target incentive compensation levels under our AIP arewhich is expressed as a percentage of the NEO’s base salary. We typically set the annual incentive target level near the median of bonus targets for comparable positions in the peer group used for benchmarking purposes. For fiscal year 2021, the Compensation Committee approved increased target incentive compensation levels for our Segment presidents, Messrs. Aulick and Fages, and for our General Counsel, Mr. Grieco, to reflect market values for comparable positions across our comparator group. For the other NEOs,2022, the Compensation Committee concluded that theirthe target annual incentive levels established target bonus levels remained appropriate for fiscal year 2021 remained appropriate, and no adjustments were made to theirthe NEOs’ target incentive levelsopportunities.

The Compensation Committee believes the plan design and financial metrics used in previous fiscal years successfully provided executives with a clear line of sight to the specific business performance necessary to drive the profitable growth and strong cash flow generation that underpin our annual operating plan and long-term growth strategy. In the view of the Compensation Committee, such plan design and financial metrics have been effective in incenting our executives to drive operating efficiencies, better cash management strategies, more disciplined price/cost and product portfolio management, and greater revenue resilience and predictability. We believe the success of our NEOs in executing on these and other priorities in the last few years has strengthened the Company’s overall resilience as a business enterprise, as demonstrated by the Company’s solid financial performance and swift recovery of stock price value during the stresses of the COVID-19 pandemic in 2020.

We are also striving to advance nonfinancial performance objectives that we believe are impactful to our stakeholders. For fiscal year 2022, the Compensation Committee introduced performance measures relating to safety and water stewardship, which are important elements of the Company’s culture and value proposition to its stakeholders. In selecting these measures, the Compensation Committee considered information provided by Meridian regarding market practices in linking executive compensation to nonfinancial performance measures and discussed potential operational and ESG-related performance measures with management. For more information about our sustainability program initiatives, see our most recent Sustainability Report, which is published annually in the spring. SAFETY PERFORMANCE The Company strives for a zero-incident workplace every day. Global worker personal safety is fundamental to the Company’s ability to maintain and preserve its workforce, assets, operations, and customers. Excellent safety performance is a global, organizational effort and a product of leadership behaviors that are foundational to overall enterprise success, such as effective governance and communication, consistent and diligent execution in accordance with policies and procedures, and well-constructed data capture and analysis. The Company’s safety program reflects continually evolving practices to advance its safety culture. WATER STEWARDSHIP PERFORMANCE Better water stewardship is a key part of the Company’s core value proposition to its customers and embodied in its purpose: Transforming Water. Enriching Life.® The Company draws on novel and existing technologies to provide its customers with more effective ways to attain their water and wastewater management goals. To address our own impact on water resources, we are measuring our water withdrawal and employing water reuse and recycling technologies, including at our ten most water-intensive facilities, which collectively account for more than 80% of our global water usage. 2023 Proxy Statement 53 The resulting composition of performance metrics approved by the Compensation Committee for the fiscal year 2022 AIP is below.

We believe this emphasis on company-wide goals fosters a culture of teamwork and organizational purpose, while setting clear expectations on operational priorities. In December 2020, at its customary AIP goal-setting meeting, the Compensation Committee decided to carry over the same performance metrics and relative weightings used for the fiscal year 2020 AIP, as set forth in the “Summary of Fiscal Year 2021 AIP Performance Metrics” table below, to the fiscal year 2021 AIP. In making this decision, the Compensation Committee considered various factors, including the following: • Continuing Pandemic Conditions in Fiscal Year 2021— Challenges in the Company’s business environment linked to the COVID-19 pandemic remained persistent and required continuation of an operating plan structured around: (a) heightened public health concerns and special operating measures to assure the health and safety of employees and customers, business resilience, supply chain continuity, and liquidity; (b) negative impacts on sales volumes due primarily to customer site access restrictions, temporary customer site closures, and temporary delays in annual maintenance activities by customers in certain end markets; and (c) labor shortages and continuing overall economic uncertainty. • Demonstrated Line of Sight Based on Fiscal Year 2020 Results— Despite the onset of the COVID-19 pandemic in early 2020, the Company achieved strong financial performance during fiscal year 2020. The Company successfully delivered stable revenues, above-target profitability (Evoqua Global Adjusted EBITDA), and above-target cash flow (Evoqua Global Adjusted Free Cash Flow) for fiscal year 2020, while maintaining the continuity of its operations throughout its nationwide network of manufacturing and service facilities, and continuing to support critical operations and processes of its customers, such as hospitals and testing labs. Importantly, there were no layoffs, furloughs, or salary reductions among the Company’s workforce due to the COVID-19 pandemic. We believe the Company’s fiscal year 2020 financial results showcased the strength of its recurring revenue business model, the diversity and breadth of its customer end markets, and the competitiveness of its unique mix of products and services. The average closing price of a share of Company common stock increased in fiscal year 2020 to $18.31 from $12.88 in fiscal year 2019, demonstrating management’s ability to create long-term value for stockholders. To maintain this positive momentum and incent our NEOs to continue executing on strategies to meet critical annual operating goals and deliver performance and value creation for our stockholders, the Compensation Committee determined it was advisable and in stockholders’ best interests to continue to use the key performance metrics of the fiscal year 2020 AIP, namely Evoqua Global Adjusted EBITDA, Segment Adjusted EBITDA and Evoqua Global Adjusted Free Cash Flow, for purposes of the fiscal year 2021 AIP, as strong indicators of the Company’s profitability and operating efficiency, effective cash management strategies, and overall enterprise resilience. 2022 Proxy Statement 61 Summary of Fiscal Year 2021 AIP Performance Metrics                Relative Weighting           Financial performance metric(1)   Who does it apply to   Keating Stas Grieco   Aulick Fages   Why it is used in our annual operating plan   Company-wide     Evoqua Global Adjusted EBITDA   All NEOs   60%   20%   Indicator of the effectiveness of our enterprise-wide business strategies and the profitability of our overall operations             Segment     Segment Adjusted EBITDA   Segment Presidents (Messrs. Aulick and Fages)   0%   40%   Indicator of the effectiveness of Segment business strategies and the profitability of Segment operations         Company-wide     Evoqua Global Adjusted Free Cash Flow   All NEOs   40%   40%   Indicator of operational efficiency and cash available for growth opportunities, repayment of debt, and other beneficial capital actions             (1) These measures are non-GAAP financial measures.

Fiscal Year 2021 AIP Funding and Achievement Levels The Compensation Committee determined the annual bonus pool for the fiscal year 2021 AIP would be established and funded only if at least 85% of the Evoqua Global Adjusted EBITDA target goal for fiscal year 2021 was achieved. The Compensation Committee determined that setting the threshold performance level at 85% of the target goal was appropriate and in the best interests of the Company and its stockholders. This threshold performance level is consistent with broader market practice and allows AIP participants to realize a fair payout level for substantial achievement of difficult performance goals. The table below sets forth the achievement levels and corresponding payouts (expressed as a percentage of target bonus) established under the fiscal year 2021 AIP with respect to each performance metric. Above-target performance may be scored on these metrics, based on applicable leverage tables, only if 100% of Evoqua Global Adjusted EBITDA is achieved. Linear interpolation is used to determine the payout percentages for results that fall between the achievement levels shown.     Below Threshold     Threshold     Target     Maximum        Performance     Payout     Performance     Payout     Performance     Payout     Performance     Payout   Evoqua Global Adjusted EBITDA     Less than 85%       0 %      85 %      25 %      100 %      100 %      115%       200%  (capped)  Evoqua Global Adjusted Free Cash Flow     Less than 90%       0 %      90 %      50 %      100 %      100 %      —(1)       —(1)   Segment Adjusted EBITDA     Less than 85%       0 %      85 %      25 %      100 %      100 %      115%     200%  (capped)  (1) Upon achieving 100% of the target goal for both Evoqua Global Adjusted EBITDA and Evoqua Global Adjusted Free Cash Flow, the payout attributable to the Evoqua Global Adjusted EBITDA and the Evoqua                 6254      AIP Performance / Payout Levels In accordance with past practice, the Compensation Committee set threshold, target, and maximum performance levels for each of the financial performance metrics under the fiscal year 2022 AIP. With respect to the ESG-related performance metrics, only a target goal was set for each metric. To receive a payout relating to an ESG-related performance metric, the goal must be achieved at the target level of performance. A summary of how our AIP operates with respect to our NEOs’ awards is provided below. Performance at Threshold    The Evoqua Global Adjusted EBITDA financial metric must achieve at least the threshold performance level (85% of target) for any metric to be earned. Performance Between Threshold and Target •  If the Evoqua Global Adjusted EBITDA financial metric is achieved between the threshold performance level and the target performance level, each other metric may be earned up to the target level on its respective performance scale. •  However, the ESG-related metrics may not be earned unless they are achieved at or above the target performance level. Performance Between Target and Maximum If the Evoqua Global Adjusted EBITDA financial metric is achieved at or above the target performance level, the Evoqua Global Adjusted EBITDA financial metric may be earned up to the maximum performance level on its performance scale. At-target performance of the Evoqua Global Adjusted EBITDA financial metric also is a precondition for above-target incentive opportunities for the other metrics, as follows: •  The Segment Adjusted EBITDA financial metric may be earned above target, up to the maximum performance level on its performance scale; and •  The above target incentive opportunity for the Evoqua Global Adjusted Free Cash Flow financial metric and the ESG-relatedmetrics is determined based onmay be unlocked, so long as target performance level has been achieved for such metric. Such metric will then be deemed to be achieved at the same performance level as the Evoqua Global Adjusted EBITDA financial metric is achieved. Maximum Performance Above target incentive opportunities for all metrics are capped at 200% of target, based on the maximum performance and applicationlevel of the leverage table for these metrics.115%. The table below sets forth the achievement levels and corresponding payout levels (expressed as a percentage of target bonus) established under the fiscal year 20212022 AIP with respect to each performance metric.

The main objectives of our long-term incentive program are to: (a) create strong alignment with stockholders’ interests through participation in stock ownership, (b) incent our executives to work towards the achievement of our long-term performance goals, (c) provide the Company a competitive means through which we may better attract able individuals to become executives, and (d) promote retention of executives through multi-year vesting periods. We set award amounts for our NEOs after taking into account market data for comparable positions in the peer group used for benchmarking purposes. The Compensation Committee adopted the current regular-cycle equity mix for our NEOs in 2019. Under our fiscal year 2021 LTIP, 50% of the NEOs’ awards consisted of stock options and the remaining 50% consisted of RSUs. The Compensation Committee believes this equity mix creates appropriate, balanced incentives for our NEOs. Stock options encourage strong alignment with stockholders’ interest in growth since options have value only to the extent that our stock price rises between the grant date and exercise date; and RSUs support retention and stock price alignment by allowing award recipients the opportunity to receive Company stock if they are still employed by us on the date the restrictions lapse. Both the options and the RSUs vest in four equal annual installments over a period of four years, provided the NEO remains employed by the Company on each of the applicable vesting dates. The table below sets forth the number of shares underlying the RSUs and options awarded to each of our NEOs on February 16, 2021.

(2) The grant date fair market value of the stock option grants is based on the Black-Scholes option pricing model. All stock option and RSU awards granted under the Amended and Restated Evoqua Water Technologies Corp. 2017 Equity Incentive Plan (the “2017 Plan”) are subject to a double trigger change in control vesting condition, as more fully described in “Payments Upon Certain Events of Termination or Change in Control.” 2021 Special Awards On May 18, 2021, the Compensation Committee approved the grant of special one-time retention awards, including RSUs (the “Special RSUs”) and PSUs (the “Special PSUs” and, collectively with the Special RSUs, the 64 “Special Awards”) under the 2017 Plan to each of the NEOs and the other executive officers. The purpose of this grant was to incentivize significant value creation and rigorous performance over the long term. Summary of Features of 2021 Special Awards Special PSUs (2/3 value of Special Award) Special RSUs (1/3 value of Special Award) • Earned incrementally over three tranches/performance periods: • Tranche 1 (2021-2022) – 25% • Tranche 2 (2021-2023) – 25% • Tranche 3 (2021-2024) – 50% • Earned PSUs, if any, cliff vest after the 3rd anniversary of the grant date • Performance is based on TSR, relative to U.S. constituents in the S&P Global Water Index • Threshold performance — 60th percentile • Target performance — 80th percentile • No payout for performance below Threshold • Payout is capped at Target, even if performance exceeds the 80th percentile • Payout will be reduced by 50% for any performance period in which the Company’s absolute TSR is negative (regardless of relative positioning) • Vest ratably over a three-year period (2022-2024) based on continued employment with the Company Special Award Determinations. The Company’s executive leadership team is widely viewed as top-notch and the Compensation Committee and the independent members of the Board became aware that certain members of the team were being solicited in a tight market for executive talent. Given the highly competitive nature of the market for executive talent and the impact that the loss of key members of the executive leadership team would have on the Company, the Compensation Committee consulted with Meridian and the independent members of the Board to evaluate various compensation strategies for retention, as applied in the ordinary course and in special, one-time situations, and for further motivating long-term, outstanding performance. During these sessions, the Compensation Committee considered, among other things, external factors, such as the market for executive talent; the contributions of the leadership team to the Company’s development and growth, particularly since becoming a publicly-traded company; strategic plans for the Company’s future growth; the overall value of promoting stability among the leadership team at this stage of the Company’s development; and stockholders’ interest in long-term stock price performance and sustained enterprise growth. The Compensation Committee ultimately determined that, given these circumstances, it was in the best interests of the Company and its stockholders to grant special one-time retention awards to Mr. Keating and the other ELT members, including the NEOs, consisting of the Special PSUs and the Special RSUs, in order to drive outperformance as well as promote retention of the leadership team during a critical period of Evoqua’s development. The Special Awards are tailored to achieve this objective by providing the leadership team (a) an opportunity to receive an enhanced payout in 2024, solely to the extent that the Company maintains TSR performance that is consistently well above its peers during the prescribed one-, two-, and three-year performance periods, as well as (b) strong retention incentives through the vesting structures of the Special PSUs and the Special RSUs. The Compensation Committee believes the overall structure of the award strongly aligns leadership performance with stockholders’ interest in sustained value creation over short-, medium- and long-term performance periods. 2022 Proxy Statement 65 Additional information regarding factors considered by the Compensation Committee is provided below. Certain Considerations Relating to the 2021 Special Awards Determination of Size of Award • Goal was to retain and motivate the leadership team • With Meridian’s assistance, considered broader market data for prior grants of similar awards by other public companies, the internal budget, and share usage and dilution • A significantly larger portion of the pool was allocated to Mr. Keating to reflect his singular role in developing, guiding, and motivating his leadership team and in establishing and executing the Company’s business strategy Selection of Relative TSR as Performance Metric • Goal was to continue to drive short-, medium-, and long-term stockholder returns and directly correlate compensation with resilient value creation for stockholders • Relative TSR strongly correlates with the stockholder experience by rewarding company TSR outperformance relative to a comparator group, and penalizing TSR median or underperformance (i.e., no payout) • The U.S. constituents of the S&P Global Water Index were selected as an appropriate comparator group, as Evoqua’s principal competitors for talent, investor capital, and customers • Strong Company performance on operational and financial results should correspond with above-peer TSR performance • Consistent above-peer performance on TSR is challenging Fit With Our Compensation Program and Strategy • Goal was to develop a one-time, standalone award that would be separate from the Company’s regular-cycle incentive programs, which already focus on driving various aspects of the Company’s financial performance �� • Awards are to be settled in equity, not cash, to ensure realized value stays correlated with stock price and aligns with our stockholders’ interests • Risk mitigation provided through our stock ownership guidelines, robust clawback policy. and capping payout (at target) on the Special PSUs (i.e., no additional payout for performance above target) Promote Exceptional Performance • Special PSUs require relative TSR performance at the 60th percentile for 50% payout (threshold level) and at the 80th percentile for 100% payout (target level) • No payout for performance below threshold • If the Company’s TSR is negative for any performance period, the number of Special PSUs that may vest for the corresponding tranche will be capped at 50% of the amount that otherwise would have been earned for such period Promote Retention • Special PSUs, which constitute 2/3 of the Special Awards, generally cliff vest and are paid, to the extent earned, only after the end of the full three-year performance period • Special RSUs, which constitute 1/3 of the Special Awards, are time-based and generally vest ratably over the same three-year period                 6656      Long-Term Incentives •  Introduced regular-cycle PSU awards in FY 2022, replacing stock options. •  PSUs have a cumulative 3-year performance period. •  PSUs cliff vest at the end of the performance period, subject to the NEO’s continued employment. •  Long-term incentives constitute approximately 66% of our CEO’s target total direct compensation and, on average, 48% of our other NEOs’ target total direct compensation under our regular-cycle compensation program. Regular-Cycle LTI Equity Mix Long-term incentives constitute the majority of our CEO’s and CFO’s target direct compensation and nearly half of the target direct compensation of our other NEOs. We use long-term incentives to: (a) create strong alignment with stockholders’ interests through our executives’ participation in stock ownership, (b) incent our executives to work towards the achievement of our long-term growth goals, (c) provide the Company a competitive means through which we may attract able individuals to become executives, and (d) promote retention of executives through multi-year vesting periods. Beginning in fiscal year 2022, the Compensation Committee introduced PSUs as one of the regular-cycle equity award vehicles for our NEOs. As a result, the 2022 LTIP equity award mix consists of 50% time-based RSUs and 50% PSUs (at target), as described in more detail below. The PSUs replaced the stock options that historically comprised 50% of our NEOs’ LTIP awards. 2022 RSUs. The 2022 RSUs vest ratably in three equal annual installments over a period of three years (i.e., on December 31, 2022, 2023, and 2024), provided the NEO remains employed by the Company on each of the applicable vesting dates. The awards, to the extent vested, will be paid in shares on a one-RSU to one-share basis. We believe that the RSUs provide a strong retention incentive and alignment with stockholders’ interest in stock price performance. 2022 PSUs. The 2022 PSUs will cliff vest, to the extent earned, after completion of the cumulative three-year performance period running from October 1, 2021 through September 30, 2024 (the “3-Year Performance Period”), provided the NEO remains employed by the Company through the end of the 3-Year Performance Period. The number of PSUs that may be earned by our NEOs upon completion of the Performance Period will be determined based on the following performance factors: • 3-Year Financial Performance Metrics. 0% to 200% of the target number of PSUs awarded to the NEO may be earned based on the Company’s achievement of two equally weighted, pre-established financial performance goals, 3-Year Average Adjusted EBITDA Margin (%) and Adjusted 3-Year Cumulative Revenue Growth Dollars ($), over the 3-Year Performance Period. • Relative TSR Modifier. After determining the number of PSUs earned based on financial performance, a relative TSR modifier will be applied, which may increase or decrease the number of PSUs in the final payout by up to 25%. As a result, the potential final payouts of the PSUs may range from 0 to 250% of target. Relative TSR Performance: Equal to or less than 25th percentile Equal to 50th percentile Equal to or greater than 75th percentile                                           Adjustment:* -25% 0 +25% * Straight-line interpolation will be used where relative TSR is between the 25th and 50th percentile and between the 50th and 75th percentile. 2023 Proxy Statement 57 Additionally, the 2022 PSUs will be settled in shares of our common stock, not cash, to ensure the realized value of the award will stay correlated with our stock price and aligned with stockholder outcomes. The awards will be paid in shares on a one-PSU to one-share basis. 2022 PSUs Performance Metrics and Target Setting The table below sets forthdescribes the amountsperformance metrics adopted for the 2022 PSUs. The Compensation Committee selected financial performance metrics that are expected to remain clear, measurable, and relevant to our long-term strategy over a multi-year performance period, are consistent with the growth-oriented mindset of the Special AwardsBoard and management, and reflect their objectives with respect to long-term value creation and stockholder outcomes. To ensure our NEOs’ pay will remain consistent with stockholder experience, the final amount of PSUs that may be earned and paid after the end of the three-year performance period is subject to adjustment by a relative TSR modifier. Weighting Definition Why it is used 3-Year Average Adjusted EBITDA Margin (%)(1)(2) 50% The average of EBITDA, as adjusted to exclude certain other items, including restructuring costs, stock-based compensation, transaction costs, acquisitions and divestitures, and certain other gains or losses, for years 1, 2, and 3, divided by revenue for years 1, 2, and 3. Indicator of the effectiveness of enterprise execution of strategies and plans to deliver sustained operating profitability and disciplined expense management, in the context of the revenue we generate. Adjusted 3-Year Cumulative Revenue Growth Dollars ($)(1)(2) 50% The cumulative increase in revenue over the three-year performance period, adjusted for acquisitions and divestitures. Indicator of the effectiveness of enterprise execution of strategies and plans to deliver sustained top-line growth. Relative TSR Modifier(3) —   This modifier may increase or decrease the aggregate number of PSUs earned with respect to the above two metrics by up to 25%, based on the Company’s TSR for the 3-Year Performance Period relative to the TSR of each of the U.S. constituents of the S&P Global Water Index, as determined at the beginning of the 3-Year Performance Period (the “TSR Peer Group”), see “Appendix D—TSR Peer Group.” Aligns management’s interests with stockholders’ interests in terms of stock performance relative to companies in the water industry, which are Evoqua’s principal competitors for talent, investor capital, and customers. (1) These performance metrics are non-GAAP financial measures. See the “Definition” column for a summary of how this metric is calculated. (2) The Company has determined that the performance achievement levels of these goals are confidential, the disclosure of which would result in competitive harm to the Company. When these performance goals were established, the Compensation Committee believed they were set at challenging yet reasonably achievable performance levels. (3) See “—2022 PSUs” above for information about the operation of the relative TSR modifier. 58 2022 LTIP Award Amounts The 2022 LTIP equity awards were granted to our NEOs.NEOs on December 31, 2021. The target amounts of such 2022 LTIP awards are provided below. After the total target equity incentive award value for each NEO was determined, the Compensation Committee split the target award value between RSUs (50%) and PSUs (50%).

In determining to grant the Special Awards, the Compensation Committee considered, among other things, the tight market for executive talent and external opportunities potentially available to members of our Executive Leadership Team. To help address this specific, one-time circumstance, the Special Awards were structured to drive exceptional Company performance, long-term value creation, and above-peer short-, medium-, and long-term stockholder returns, while strengthening the retention incentive. The Special PSUs make up two-thirds, and the Special RSUs one-third, of the value of each Special Award. Subject to the applicable NEO’s continued employment with the Company and the terms and conditions of the 2017 Plan and the related award agreement, (a) the Special RSUs will vest ratably over a three-year period on each annual anniversary of the grant date, May 18, 2021, and, (b) in order to incent sustained value creation over short-, medium-, and long-term periods, the Special PSUs will be earned incrementally in three tranches of 25%, 25%, and 50% after one-, two- and three-year performance periods, respectively, as delineated in the tables below, and will cumulatively be paid, if earned, after the endcompletion of the three-year performance period ending on May 18, 2024 (the “Total Performance Period”), based on the Company’s TSR as compared to the U.S. constituents of the S&P Global Water Index, asTSR Peer Group listed on “Appendix B—2021 Special AwardsD—TSR Peer Group.” Each tranche of the Special PSUs reflects the right to receive between 50% to 100% of the shares underlying such tranche, if earned, based on the Company’s TSR as compared to such companies (“Relative TSR”) for the applicable performance period. Subject to certain exceptions provided in the award agreements in the event of death, disability or change in control (as more fully described in this Proxy Statement under the heading “Payments Upon Certain Events of Termination or Change in Control”), for each tranche, Special PSUs will be earned based on the followingrelative TSR performance levels:level attained for the applicable performance period, as follows:     Performance Level Relative TSR % of Tranche Earned Target Equal To or Greater Than 80th Percentile 100% Threshold 60th Percentile 50% Below Threshold Below 60th Percentile 0% Special PSUs—Tranches                Special  PSUs—Performance Levels Performance Period    Allocation of   Units         Performance Level    Relative TSR    % of Tranche   Earned Tranche 1 (2021—2022)    25%       Target (Maximum)    Equal To or Greater Than 80th Percentile    100% Tranche 2 (2021—2023)    25%       Threshold    60th Percentile    50% Tranche 3 (2021—2024)    50%       Below Threshold    Below 60th Percentile      0% Linear interpolation will be used to determine the percentage of each tranche earned when the Company’s Relativerelative TSR falls between the 60th percentile and the 80th percentile for the applicable performance period. The payout for each tranche of the Special PSUs iswill be capped at target (or 100%(i.e.,100%) even if the Company’s Relativerelative TSR exceeds the target at the 80th percentile for the applicable performance period. If the Company’s TSR is negative for any performance period, the number of Special PSUs that may vest for the corresponding tranche will be capped at 50% of the amount that otherwise would have been earned for such period. Compensation Program Changes for Fiscal Year 2022 Fiscal Year 2022 AIP Performance Metrics and Goals For fiscal year 2022, the Compensation Committee determined to incorporate two new ESG-related performance metrics described below into the Company’s AIP. These goals are based on two of the defining elements of the Company’s culture, water stewardship and safety, and are intended to focus executives on the achievement of the Company’s broader sustainability goals.        20222023 Proxy Statement           6759   In NovemberTranche 1 Performance Result For the first performance period (May 18, 2021 the Compensation Committee approved the following performance metrics and weightings for– May 18, 2022), the Company’s fiscal year 2022 AIP (with payouts ranging from 0-200%one-year relative TSR was ranked at the 96th percentile compared to the TSR Peer Group.

(2) If 100% of the target goal for Evoqua Global Adjusted EBITDA and this metric is achieved, the payout attributableSpecial PSUs allocated to this metric is determined based on Evoqua Global Adjusted EBITDA performance and the applicable leverage tables. (3) Performance will be measured based on achieving a target level of water reuse/recycling vs. water withdrawn from source at Evoqua’s ten most water-intensive facilities (4) Performance will be measured based on achieving a target Total Recordable Incident Rate (TRIR), as calculated in accordance with OSHA requirements. The fiscal year 2022 AIP will only fund if the Company’sfirst performance equalsperiod, or exceeds 85% of its target Global Adjusted EBITDA goal. Payouts under the fiscal year 2022 AIP will be determined based on (a) the attainment25% of the selected financial performance goals at threshold,total target or above-target levels, and (b) the absolute attainmentnumber of the selected ESG-related performance goals (i.e., all or nothing payout). Similar to the fiscal year 2021 AIP, above-target performance may be scored on these metrics, based on applicable leverage tables, only if 100% of Evoqua Global Adjusted EBITDA is achieved.The Compensation Committee approved performance goals for the fiscal year 2022 AIP that it believes to be challenging, but reasonably achievable. Fiscal Year 2022 LTIP Design In November 2021, the Compensation Committee approved the design of the Company’s fiscal year 2022 LTIP (the “FY 2022 LTIP”). The equity mix for the FY 2022 LTIP will include 50% PSUs (at target) (the “FY 2022 PSUs”) and 50% RSUs. The FY 2022 PSUs are a new component of the Company’s LTIP for fiscal year 2022, replacing the stock options that historically have comprised 50% of the Company’s LTIP program. 68 The RSUs will generally vest in three equal annual installments over a period of three years, provided the NEO remains employed by the Company on each of the applicable vesting dates. To the extent earned, the FY 2022 PSUs will cliff vest at the end of a cumulative three-year performance period based on achievement of goals related to the following performance metrics (with payouts ranging from 0-200% of target depending on performance):Special PSUs.     Performance MetricName    Relative WeightingTranche 1                 Special PSUs                 Earned  (#)*                   Measurement Method(1) Sustained Improvement in Revenue Growth      50%Target/Max Performance: ≥ 80th Percentile       Actual Performance:     96th Percentile   Three-Year Cumulative Organic Revenue Growth Dollars ($)    Outperformed Target   Sustained Improvement in ProfitabilityRon C.

Other Compensation Program Elements Employment Agreement and Equity Award Terms We have entered into employment agreements and equity award agreements with each of our NEOs to be market competitive and promote the stability of our executive team through the payment of severance and vesting or continued vesting of such equity awards in the event of certain employment termination events relating to death, disability, retirement, termination without cause, termination by the NEO for good reason, and a qualifying employment termination associated with a change in control (double trigger) as more fully described in the sections titled “Employment Agreements” and “Payments Upon Certain Events of Termination or Change in Control.” Retirement Plans The Company provides retirement benefits to the NEOs, including discretionary matching and profit-sharing contributions, under the terms of its tax-qualified defined contribution plan (the “401(k) Plan”). The NEOs may participate in the 401(k) Plan on the same terms as our other participating employees. Beginning January 1, 2021, the CompanyThe Company’s matching contribution is made annually following the end of the calendar year and using a formula of 100% of a participant’s elective deferrals up to 4% of the participant’s compensation. A participant must be employed on the last day of the calendar year to receive the Company matching contribution, except in the case of the participant’s death, disability, or termination of employment after attaining age 65. Beginning January 1, 2021, the CompanyThe Company’s profit-sharing contribution is made annually following the end of the calendar year and using a formula of 4% of a participant’s compensation for the calendar year. A participant must have one year of service in order to receive any Company profit-sharing contribution. In addition, a participant must be employed on the last day of the Company’s fiscal year (September 30) to receive the Company profit-sharing contribution, except in the case of the participant’s death, disability, or termination of employment after attaining age 65. Company matching and profit-sharing contributions vest on a three-year graded schedule. Upon three years of continuous service with the Company, employees are fully vested in Company contributions. The Company also maintains a nonqualified deferred compensation plan (the “Deferred Compensation Plan”) in which the NEOs may participate. Under the Deferred Compensation Plan, the NEOs may elect to defer portions of their base salary, 60 short-term incentives, and sales commissions/bonuses, and they may receive certain Company matching contributions. For a further description of the Deferred Compensation Plan and the payments that were made in fiscal year 2021,2022, please see the table titled “Nonqualified Deferred Compensation”Compensation—Fiscal Year 2022” below. 2022 Proxy Statement 69 We believe the retirement benefits provided under the 401(k) Plan and the Deferred Compensation Plan are comparable to those provided by comparable companies. The Company does not maintain any defined benefit plans for any of its executive officers. Perquisites and Other Personal Benefits TheThrough a reimbursement plan, the Company provides the NEOs with perquisites and other personal benefits or an allowance for certain perquisites, that it believes are reasonable and consistent with its overall compensation program to better enable the Company to attract and retain superior employees for key positions. Since July 2018,Under the Company has maintained aCompany’s reimbursement plan, pursuant to which the CEO, and executive and senior vice presidents and vice presidents may incur qualifying expenses related to executive physicals, financial planning, health club and/or social club dues and fees, personal automobile, parking, and charitable donations, which will be reimbursed by the Company up to the applicable reimbursement limit. The reimbursement limits (not including any amounts to cover taxes) are: $30,000 for Mr. Keating; $25,000 for Mr. Stas; and $20,000 for each of Messrs. Aulick, Fages, and Grieco. For Mr. Keating, the reimbursement plan also covers payment of social club dues having an aggregate value of up to an additional $30,000. The Compensation Committee periodically reviews the levels of perquisites and other personal benefits that may be made available to our NEOs through the reimbursement program to confirm that such levels are reasonable and continue to serve their intended retentive purposes. Stock Ownership Guidelines The Compensation Committee believes our officers should own a significant amount of Evoqua common stock to strongly align their interests with our stockholders’ interests. Accordingly, inIn April 2018, the Compensation Committee adopted stock ownership guidelines applicable to all of our officers based on a multiple of base salary. Officers are expected to meet these ownership requirements within five years of election, appointment, or promotion. At November 17, 2021,7, 2022, each of our NEOs was in compliance with our stock ownership guidelines. The current stock ownership requirements applicable to our executive officers are:       CEO    5X annual base salary Executive Officers    3X annual base salary Shares that count towards satisfaction of the stock ownership guidelines for our officers include the following:   Shares owned directly by the officer, or by his or hertheir immediate family members residing in the same household (whether acquired through a Company-sponsored equity-based compensation plan or program of the Company, or otherwise);   Shares held in trust for the benefit of the officer, or his or hertheir immediate family members;   Vested shares held in the officer’s retirement accounts; and   Shares of restricted stock, restricted stock units,RSUs, or deferred stock units that may only be settled in shares, whether vested or unvested. Clawback Policy In February 2019, the Company adopted a clawback policy that applies to all current and former executive officers (including the NEOs), employees at the vice president level and above (together with current and former executive officers, the “Covered Executives”), and other designated employees of the Company and its subsidiaries (the “Participating Employees”). The policy provides that, in the event the Company is required to prepare an accounting restatement of financial statements due to the Company’s material noncompliance with any financial reporting requirement under the federal securities laws, the Company 2023 Proxy Statement 61 will make a reasonable attempt to obtain reimbursement or forfeiture of any excess incentive compensation received by a Covered 70 Executive during the three completed fiscal years immediately preceding the date the Company is required to prepare an accounting restatement. Separately, if it is determined that a Covered Executive has willfully, knowingly, or intentionally engaged in misconduct, an intentional violation of any of the Company’s rules or any applicable legal or regulatory requirements, fraud or other illegal conduct, which either contributed to the circumstances requiring an accounting restatement or otherwise caused economic or reputational damage to the Company, and the Compensation Committee determines it would be appropriate to seek recovery under the policy, the Company will make a reasonable attempt to recover up to 100% of the incentive compensation that was paid to the Covered Executive or Participating Employee during the three completed fiscal years immediately preceding the date the Company is required to prepare an accounting restatement. Securities Trading Policy To ensure alignment ofalign the interests of our stockholders and executive officers, including our NEOs, as well as complianceand comply with applicable securities laws, the Company’s Securities Trading Policy (i) prohibits all directors, officers, and employees from engaging in transactions involving the Company’s stock based on material non-public information or communicating material non-public information to any person who uses that information to purchase or sell Company securities, and (ii) requires directors, executive officers (including the NEOs) and certain other designated employees (as identified in the Securities Trading Policy) to preclear any trading in Company securities, whether or not during an open trade window (except that such policies shall not apply to the exercise of options not involving a market sale to generate cash to pay the exercise price, the vesting of restricted stock or restricted stock unitRSU awards or transactions in accordance with a previously established trading plan that meets SEC requirements). The policySecurities Trading Policy also prohibits the Company’s directors and executive officers from engaging in hedging and pledging activities, as more fully described in this Proxy Statement under the heading “Corporate Governance.”        2022 Proxy Statement      62    71   REPORT OF THE COMPENSATION COMMITTEE OF THE BOARDREPORT The Compensation Committee reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with management, and, based on such review and discussions, the Compensation Committee recommended to the Board that the Compensation Discussion and Analysis be included in this Proxy Statement.

Annual Incentive Plan. The amounts of annual cash incentive compensation earned in fiscal year 20212022 by our NEOs were determined at the end of November 20212022 and paid in December 2021.2022. The amounts paid are included in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table—Fiscal Years 2022, 2021, 2020, and 2019.2020. 2022 Proxy Statement 75 (2) These amounts reflect the threshold, target, and maximum number of PSUs that may be paid out to our NEOs under the 2017 Plan pursuant to the Company’s fiscal year 2022 LTIP. The threshold amount reflects application of a relative TSR modifier of -25%, and the target and maximum amounts each reflect application of a relative TSR modifier of +25%. To the extent earned, the PSUs will vest at the end of a three-year Performance Period (2022 – 2024) based on the achievement of the relevant performance goals over the Performance Period. See the section of the CD&A titled “—Long-Term Incentives” above. (3) The amounts in this column represent the aggregate grant date fair value of the stock awards, as computed in accordance with FASB ASC Topic 718, excluding the effect of estimated forfeitures. Assumptions used in calculating the amounts in this column are set forth in Note 18 to the Consolidated Financial Statements in our Form 10-K. For the RSUs and the Special RSUs, the grant date fair value was computed based on the closing price per share of the Company’s common stock on the date of grant, multiplied by the number of shares awarded. Because the Special PSUs are subject to performance conditions, the grant date fair value shown is based on performance at target levels, which is the probable outcome of such conditions. For the options, the values were calculated using a Black-Scholes option pricing model. (3) Represents regular-cycle long-term incentive awards made under made under the 2017 Plan. These awards vest over a four-year period, with 25% of the awards vesting on each of the first, second, third, and fourth anniversaries of the grant date. See the section of the CD&A titled “—Long-Term Incentives” above. (4) Represents special long-term incentive awards madeThese amounts reflect the number of RSUs granted to our NEOs under the 2017 Plan. Special PSUs will be earned incrementally in three tranches of 25%, 25%, and 50% after one-, two-, and three-year performance periods, respectively, and will cumulatively be paid, if earned, afterPlan pursuant to the end of the three-year performance period ending on May 18, 2024.Company’s fiscal year 2022 LTIP. The target payout level also represents the maximum payout level. Special RSUs will vest ratably over a three-year period with 33-1/3% of the awards vesting on each of the first, second, and third anniversaries of the grant date. See the section of the CD&A titled “—Long-Term Incentives” above. 66 Employment Agreements We have entered into employment agreements with each of our NEOs and believe these agreements have helped create stability for our management team.

The Deferred Compensation Plan uses a tracking account for each participant who elects to defer income. The participant selects investment funds from a broad range of options. Earnings and losses on each account are determined based on the performance of the investment funds selected by the participant. A participant may elect to defer up to 50% of his annual base compensation and up to 90% of his bonus awarded pursuant to the AIP as compensation deferrals. The NEOs are 100% vested with respect to both employee contributions and their employer contributions. Distributions under the Deferred Compensation Plan may be made as a single lump sum, on a fixed date or schedule, or in equal installments over periods of (x) five, 10, or 15 years or (y) two, three, four, or five years, depending on the distribution’s triggering event and the participant’s elections, in compliance with the election and timing rules of Section 409A of the Internal Revenue Code Section 409A.of 1986, as amended (the “Code”). PAYMENTS UPON CERTAIN EVENTS OF TERMINATION OR CHANGE IN CONTROL As discussed below, each of our NEOs may receive various forms of compensation or benefits in the event of termination of his employment under certain circumstances. Accrued Benefits Payable Upon Termination Pursuant to their employment agreements, in the event of termination of employment for any reason, each of our NEOs is generally entitled to the following payments and benefits:   Earned but unpaid salary through the termination date;   Earned but unpaid annual incentive compensation pertaining to a fiscal year completed prior to the termination date;   Unused vacation days paid out at the NEO’s per-business-day base salary rate;   Vested benefits, if any, in accordance with the terms of applicable Company arrangements; and   Any unreimbursed expenses (collectively, the “Accrued Amounts”). However, in the event the NEO’s employment has been terminated by the Company for Cause (as defined below), any annual incentive compensation amounts earned in respect of a prior fiscal year, to the extent not yet paid or due to be paid, shall be forfeited. Severance Benefits Payable Upon Certain Involuntary Terminations Pursuant to their employment agreements, in addition to the Accrued Amounts, certain severance payments and benefits may be payable to each of our NEOs in the event (i) the Company terminates his employment other than for Cause (including, in the case of Messrs. Aulick, Fages, and Grieco, termination by the Company due to a non-renewal of the NEO’s employment agreement), death or Disability (pursuant to the terms of equity award agreements); or (ii) the NEO terminates his employment for Good Reason. Definitions of the terms “Cause,” “Disability” and “Good Reason” are provided below under “—Definitions for Triggering Events.” The severance payments and benefits, other than in connection with a Change in Control (described below), generally consist of:of the following:   Base salary continuation for a period of 24 months in the case of Mr. Keating, and 12 months in the case of the other NEOs, which is to be paid in equal installments on the Company’s regular payroll dates;   A pro rata portion of the annual incentive compensation that would have been payable to the NEO based on the Company’s actual performance in the year of termination (the “Prorated Bonus”), which is to be paid at the same time such compensation is paid to the Company’s other senior executives;   Medical and dental benefits continuation for a maximum of 12 months; and   Reimbursement for outplacement assistance for six months up to a maximum of $15,000.        2023 Proxy Statement        8273   Additionally, each of Messrs. Keating and Stas is eligible to receive enhanced severance payments and benefits in the event his employment is terminated within two years of a “Change in Control,” including: (i) a lump sum payment in an amount equal to the sum of (x) the relevant multiple of his base salary (2.5x times for Mr. Keating; 2x for Mr. Stas), plus (y) the relevant multiple of his target annual incentive compensation opportunity (2.5x for Mr. Keating; 2x for Mr. Stas), plus (z) a pro rata portion of his target annual incentive compensation opportunity in the year of termination; and (ii) the full vesting of any outstanding unvested equity awards issued by the Company to the NEO (in(for additional information regarding the casetreatment of the Special PSUequity awards, subject to the attainment of the applicable performance goals)see “—Equity Treatment” below). Such enhancements of base salary continuation and annual incentive compensation would be paid in lieu of the base salary continuation and annual incentive compensation payments described above. These severance payments and benefits are conditioned upon (i) the NEO’s continued compliance with his obligations pursuant to the restrictive covenants (including confidentiality, non-competition, non-solicitation, and interference with business relationships, among others), contained in his employment agreement, and (ii) the NEO’s execution, delivery, and non-revocation of a valid and enforceable general release of claims in favor of the Company within 45 days after the termination date. Pursuant to the employment agreements, in the event of any breach or threat of breach of the restrictive covenants contained therein, the Company will be entitled to an immediate injunction and restraining order to prevent such breach and/or threatened breach and/or continued breach, without having to prove damages, in addition to any other remedies to which the Company may be entitled at law or in equity, including, without limitation, the obligation of the NEO to return any portion of the severance payments paid by the Company to the NEO. Definitions for Triggering Events. The terms “Cause,” “Disability,” and “Good Reason” used in the NEOs’ employment agreements and equity award agreements generally are defined as set forth below. “Cause,” as used in the employment agreement and award agreements, means the NEO has engaged in any of the following: (i) commission of an act which constitutes common law fraud, embezzlement or a felony, an act of moral turpitude, or of any tortious or unlawful act causing material harm to the business, standing or reputation of the Company or any of its affiliates, (ii) gross negligence on the part of the NEO in the performance of his duties hereunder, (iii) breach of his duty of loyalty or care to the Company, (iv) other misconduct that is materially detrimental to the Company or any of its affiliates, or (v) ongoing and deliberate refusal or failure to perform the NEO’s duties as contemplated by his employment agreement or any other agreement with or for the benefit of the Company to which the NEO is a party or by which the NEO is bound, which in the case of a failure that is capable of being cured, is not cured to the reasonable satisfaction of the Board within 30 days after the NEO receives from the Company written notice of such failure, provided that for the avoidance of doubt a failure to meet performance expectations shall not in of itself constitute Cause. “Disability,” as used in the employment agreements, means the NEO is entitled to and has begun to receive long-term disability benefits under the long-term disability plan of the Company in which the NEO participates, or, if there is no such plan, the NEO’s inability, due to physical or mental ill health, to perform the essential functions of the NEO’s job, with or without a reasonable accommodation, for 180 days out of any 270 day270-day consecutive day period. “Disability,” as used in the award agreements, means a permanent and total disability as defined in Code Section 22(e)(3). A determination of Disability may be made by a physician selected or approved by the Compensation Committee and, in this respect, the NEO shall submit to any reasonable examination(s) required by such physician upon request. Notwithstanding the foregoing, in the event any award is considered to be “deferred compensation” as that term is defined under Section 409A of the Code and the terms of the award are such that the definition of “disability” is required to comply with the requirements of Section 409A of the Code then, in lieu of the foregoing definition, the definition of “Disability” for purposes of such award shall mean, with respect to a NEO, that the NEO is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than 12 months. “Good Reason,” as used in the employment agreements, means one of the following has occurred: (i) a material and adverse change in the NEO’s duties or responsibilities as an employee of the Company, (ii) a breach by the Company of a material term of the NEO’s employment agreement or, (iii) in the case of Messrs. Keating, 2022 Proxy Statement 83 Stas, and Aulick, a relocation of the NEO’s principal place of employment without his consent, which, in the case of each of (i)-(iii), has not been cured by the Company within 30 days of the NEO providing written notice to the Company of his termination of employment for Good 74 Reason. However, in the case of Mr. Keating, “Good Reason” shall not exist pursuant to subpart (i) above if the Company has been acquired in a strategic transaction and Mr. Keating continues to report to the most senior executive of the division, unit, or sector of the post-transaction organization in which the Company’s business is resident, or to an individual who is senior to such senior executive. As used in the award agreements for each of the NEOs and in the employment agreements of Messrs. Keating and Stas, the term “Change in Control” is defined with reference to the 2017 Plan. Under this plan, a Change in Control is deemed to have occurred upon the occurrence of any of the events listed below.   An acquisition (other than directly from the Company) of any voting securities of the Company (the “Voting Securities”) by any person, immediately after which such person first acquires “Beneficial Ownership” (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 50% or more of the combined voting power of the Company’s then-outstanding Voting Securities; provided, however, that the acquisition of Voting Securities in a Non-Control Acquisition (as defined below) shall not constitute a Change in Control. A “Non-Control Acquisition” shall mean an acquisition by (i) an employee benefit plan (or a trust forming a part thereof) maintained by (A) the Company or (B) any corporation or other person, the majority of the voting power, voting equity securities, or equity interest of which is owned, directly or indirectly, by the Company (for purposes of this definition, a “Related Entity”), (ii) the Company or any Related Entity or (iii) any person in connection with a Non-Control Transaction (as hereinafterdefined below);   The individuals who are members of the Board (the “Incumbent Board”), cease for any reason to constitute at least a majority of the members of the Board; provided, however, that if the election, or nomination for election by the Company’s common stockholders, of any new director, was approved by a vote of at least two-thirds of the Incumbent Board, such new director shall be considered as a member of the Incumbent Board; provided further, however, that no individual shall be considered a member of the Incumbent Board if such individual initially assumed office as a result of either an actual or threatened solicitation of proxies or consents by or on behalf of a person other than the Board (a “Proxy Contest”) including by reason of any agreement intended to avoid or settle any Proxy Contest;   The consummation of:   (i) A merger, consolidation, or reorganization (x) with or into the Company or (y) in which securities of the Company are issued (a “Merger”), unless such Merger is a Non-Control Transaction. A “Non-Control Transaction” shall mean a Merger in which:   (A) the stockholders of the Company immediately before such Merger own directly or indirectly immediately following such Merger at least a majority of the combined voting power of the outstanding voting securities of (1) the corporation resulting from such Merger (the “Surviving Corporation”), if fifty percent (50%) or more of the combined voting power of the then outstanding voting securities of the Surviving Corporation is not Beneficially Owned, directly or indirectly, by another person (a “Parent Corporation”), or (2) if there is one or more than one Parent Corporation, the ultimate Parent Corporation;   (B) the individuals who were members of the Board immediately prior to the execution of the agreement providing for such Merger constitute at least a majority of the members of the board of directors of (1) the Surviving Corporation, if there is no Parent Corporation, or (2) if there is one or more than one Parent Corporation, the ultimate Parent Corporation; and   (C) no person other than (1) the Company or another corporation that is a party to the agreement of Merger, (2) any Related Entity, (3) any employee benefit plan (or any trust forming a part thereof) that, immediately prior to the Merger, was maintained by the Company or any Related Entity, or (4) any person who, immediately prior to the Merger, had Beneficial Ownership of Voting Securities representing more than fifty percent (50%) of the combined voting power of the Company’s then-outstanding Voting Securities, has Beneficial Ownership, directly or indirectly, of 50% or more of the combined voting power of the outstanding voting securities of (x) the Surviving Corporation, if there is no Parent Corporation, or (y) if there is one or more than one Parent Corporation, the ultimate Parent Corporation; 84 indirectly, of 50% or more of the combined voting power of the outstanding voting securities of (x) the Surviving Corporation, if there is no Parent Corporation, or (y) if there is one or more than one Parent Corporation, the ultimate Parent Corporation;   (ii) A complete liquidation or dissolution of the Company; or   (iii) The sale or other disposition of all or substantially all of the assets of the Company and its Subsidiaries taken as a whole to any person (other than (x) a transfer to a Related Entity or (y) the distribution to the Company’s stockholders of the stock of a Related Entity or any other assets). 2023 Proxy Statement 75 Notwithstanding the foregoing, a Change in Control shall not be deemed to occur solely because any person (the “Subject Person”) acquired Beneficial Ownership of more than the permitted amount of the then outstanding Voting Securities as a result of the acquisition of Voting Securities by the Company which, by reducing the number of Voting Securities then outstanding, increases the proportional number of shares Beneficially Owned by the Subject Person; provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of Voting Securities by the Company and, after such acquisition by the Company, the Subject Person becomes the Beneficial Owner of any additional Voting Securities and such Beneficial Ownership increases the percentage of the then outstanding Voting Securities Beneficially Owned by the Subject Person, then a Change in Control shall occur. Equity Treatment If a NEO’s employment is terminated, the treatment of his equity awards will generally be based on the terms of the applicable equity plan and the award agreements adopted by the Compensation Committee to evidence the awards granted under such plan, unless otherwise provided in the NEO’s employment agreement (provided, however, that with respect to performance share unit awards,PSUs, the amount or number of such performance share unitsPSUs that become earned by the NEO based on the achievement of the applicable performance metrics will be solely determined pursuant to the terms of the applicable award agreement). A summary of the provisions of the 2017 Plan and the award agreements that govern the treatment of our NEOs’ equity awards is set forth below.   Termination of Employment Without Cause (Other than Death, Disability, Retirement, or Change in Control):    •  Options: Unvested options will be forfeited.   •  RSUs and Special RSUs: Unvested RSUs and Special RSUs will be forfeited.   •  PSUs: Unearned PSUs will be forfeited. •  Special PSUs: Earned Special PSUs will fully vest; unearned Special PSUs will be forfeited.   Termination of Employment due to Death or Disability:    •  Options: • Granted Prior to 2/14/19: Unvested options will be forfeited. • Granted on or After 2/14/19: Unvested options will fully vest.   •  RSUs: Unvested RSUs will fully vest.   •  PSUs: Unearned PSUs will remain eligible to vest as if the NEO had remained employed for the full performance period; a pro rata portion of the earned PSUs will vest.(1) •  Special RSUs: A pro rata portion of the Special RSUs will vest.(1)(2)   •  Special PSUs: A pro rata portion of each tranche of the Special PSUs will vest.(2)(3)   Retirement Eligible Termination of Employment Without Cause(3)Cause(4):    •  Options: Unvested options will continue to vest in accordance with the original vesting schedule; vested options will remain exercisable until the expiration of the option term.   •  RSUs: Unvested RSUs will continue to vest in accordance with the original vesting schedule.   •  PSUs: Unearned PSUs will remain eligible to vest as if the NEO had remained employed for the full performance period; a pro rata portion of the earned PSUs will vest.(1) •  Special RSUs and Special PSUs: Not applicable.   Termination of Employment With Cause:    •  Options, RSUs, PSUs, Special RSUs, and Special PSUs: Both unvested awards and vested, but unsettled, awards will be forfeited.          2022 Proxy Statement      76    85   Termination of Employment Without Cause or Good Reason, as Applicable, Following a Change in Control: Control (assumes the acquirer assumed outstanding equity awards following a Change in Control):    •  Options: • Granted Prior to 2/14/19: Unvested options will be forfeited. • Granted on or After 2/14/19: If termination occurs within the 24-month period, in the case of Messrs. Keating and Stas, or 12-month period, in the case of the other NEOs, following a Change in Control, unvested options will fully vest.   •  RSUs: If termination occurs within the 24-month period, in the case of Messrs. Keating and Stas, or 12-month period, in the case of the other NEOs, following a Change in Control, unvested RSUs will fully vest. •  PSUs: If termination occurs within the 24-month period, in the case of Messrs. Keating and Stas, or 12-month period, in the case of the other NEOs, following a Change in Control prior to the last day of the Performance Period, all PSUs will be deemed earned at a target performance level and will vest.   •  Special RSUs: If termination occurs following a Change in Control and prior to the third anniversary of the grant date, unvested Special RSUs will fully vest.   •  Special PSUs:   •  Modified Change in Control: If a Modified Change in Control occurs prior to the last day of the Total Performance Period, all Special PSUs will be deemed earned at a target performance level and will be subject to time-based vesting based on continued employment until the last day of the Total Performance Period. If termination occurs prior to the last day of the Total Performance Period, all earned Special PSUs will vest.(4)(5)   •  Change in Control: If termination occurs following a Change in Control (under circumstances other than a Modified Change in Control) and prior to the last day of the Total Performance Period, earned Special PSUs will vest and each tranche of Special PSUs for a current or future performance period will remain eligible to be earned subject to the attainment of the applicable performance goal.     (1) Proration will be calculated as follows: (i) the total number of earned PSUs for the Performance Period multiplied by (ii) a fraction with the numerator equal to the number of calendar days that elapsed from the first day of the Performance Period until termination and the denominator equal to 1,096.   (1)(2) Proration will be calculated as follows: (i) the total number of Special RSUs subject to the award multiplied by (ii) a fraction (x) the number of calendar days between the grant date and the date of death or disability, as applicable, divided by (y) 1,096, less (iii) the number of Special RSUs originally subject to the award that have already become vested.   (2)(3) Earned Special PSUs for previously completed performance periods will vest on a pro rata basis based on actual performance for the completed period. Special PSUs for incomplete performance periods will become earned on the termination date (scored with the termination date deemed as the final day of the applicable performance period) and will vest on a pro rata basis. In each case, proration will be calculated as follows: (i) the total number of earned Special PSUs for each performance period multiplied by (ii) a fraction with the numerator equal to the number of calendar days that elapsed from the first day of the Total Performance Period until termination and the denominator equal to 1,096.   (3)(4) Applies only to awards under the 2017 Plan made on or after February 14, 2019. An award holder is considered “retirement eligible” if he or she has given prior written notice of intent to retire at least six months prior to the effective date of retirement, and either (i) has attained age 65 or (ii) has attained age 55 and completed at least 10 consecutive years of service with the Company.   (4)(5) For the Special PSUs, the term “Modified Change in Control” means a “Change in Control” as defined in the 2017 Plan, except that for purposes of defining a “Merger” that would constitute a “Non-Control Transaction” (which would not constitute a Modified Change in Control): (i) subsections (A) and (C) of such definition are omitted; and (ii) subsection (B) of such definition means, continuously through May 18, 2024, following the execution of an agreement providing for such Merger, the individuals who were members of the Board immediately prior to the execution of the agreement providing for such Merger constitute at least a majority of the members of the board of directors of (1) the Surviving Corporation, if there is no Parent Corporation, or (2) if there is one or more than one Parent Corporation, the ultimate Parent Corporation.        2023 Proxy Statement        8677   Estimated Payments and Benefits The following tables describe the estimated value of payments and benefits that would have been due to each NEO in the event his employment was terminated on September 30, 20212022 (in addition to any accrued but unpaid benefits that may be applicable as of such date), under the circumstances delineated in the tables. None of the NEOs was eligible to retire as of September 30, 2021.2022.

RISK ASSESSMENT In conjunction with the development of the fiscal year 20212022 compensation program, the Compensation Committee reviewed the compensation program to determine if the program elements encourage excessive or unnecessary risk-taking that is reasonably likely to have a material adverse effect on the Company. The Compensation Committee believes the Company’s compensation program offers an appropriate mix of fixed compensation and short- and long-term variable compensation which alignthat aligns with the Company’s business strategy. In addition, the Compensation Committee believes that its discretion and authority in making decisions related to executive compensation, as well as the caps on annual and long-term incentive payouts, stock ownership guidelines, and clawback policy, all serve to mitigate excessive risk. Finally, as noted above, the Compensation Committee engaged Meridian as its independent compensation consultant to advise on matters related to fiscal year 20212022 compensation design decisions for the Company’s executive officers. As a result, the Compensation Committee believes that our compensation program does not encourage unreasonable risk-taking that is reasonably likely to have a material adverse effect on the Company. CEO PAY RATIO In accordance with SEC rules, we are providing the ratio of the annual total compensation of our CEO to the annual total compensation of our median employee. Using the methodology described below, we calculated the annual total compensation of our median employee for fiscal year 20212022 to be $92,260.$81,465. As reported in the Summary“Summary Compensation Table — Table—Fiscal Years 2022, 2021, 2020, and 20192020” in this Proxy Statement, the annual total compensation of our CEO for fiscal year 20212022 was $15,660,392.$6,001,562. Based on this information, the ratio of the annual total compensation of our CEO to the annual total compensation of our median employee for fiscal year 20212022 was 170:74:1.        2023 Proxy Statement        9687   The fiscal year 20212022 annual total compensation of our median employee was calculated based on the same requirements thatwhich apply to the determination of total compensation for the Summary“Summary Compensation Table — Table—Fiscal Years 2022, 2021, 2020, and 2019,2020,” and includes: base salary earned and paid from October 1, 20202021 through September 30, 2021;2022; incentive plan payments (both non-equity and equity-based) made for the performance period October 1, 20202021 through September 30, 2021;2022; and other compensation earned or paid in fiscal year 2021.2022. Our median compensated employee is an individual located in the U.S. To identify our median employee, we selected August 1, 20212022 as our determination date. On that date, we had a total of 4,0374,525 employees (3,057(3,477 U.S. employees and 9801,048 non-U.S. employees), constituting all full-time, part-time, seasonal and contingent/temporary workers employed by the Company and its consolidated subsidiaries, except our CEO. The foregoing total does not include workers we lease from unaffiliated third parties and whose compensation was determined by such third parties. Pursuant to the de minimis exemption under SEC rules, we excluded from the aforementioned total employee population our employees in countries which, in the aggregate, constitute less than 5% of our total global employee population, as detailed in the table below.   Jurisdictions Excluded from Employee Population (Total of 198 employees estimated as of August 1, 2021) Australia    28    Mexico    2 Egypt    1    Netherlands    70 France    13    Poland    1 Greece    1    Russian Federation    1 Republic of Ireland    4    Singapore    63 Japan    1    Taiwan    2 Republic of Korea    5    United Arab Emirates    2 Malaysia    4               Jurisdictions Excluded from Employee Population (Total of 143 employees estimated as of August 1, 2022) Australia    26    Republic of Korea    4 Austria    1    Malaysia    1 Bahrain    1    Mexico    3 France    13    Netherlands    81 Greece    1    Poland    1 Ireland    4    Taiwan    1 Japan    1    United Arab Emirates    5 We then compared the annual base salaries,fiscal year 2022 regular earnings (base salary or hourly wages, cash incentive payments, cash commissions, overtime pay, or other similar payments), as a consistently applied compensation measure, of the remaining 3,839 employees (other than our CEO).4,382 employees. In the case of hourly employees annual base salary was determined by multiplyinghired within the hourly compensation rate byfiscal year or terminated prior to the employee’s target annual work schedule.fiscal year-end, their regular earnings were annualized. We did not make any cost-of-living adjustments. Any base salaryamounts paid in a foreign currency was converted to U.S. Dollars at prevailing exchange rates as of August 1, 2021.2022. The CEO pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on the methodologies, estimates, and assumptions described above. SEC rules for identifying the median employee and determining the CEO pay ratio permit companies to employ a wide range of methodologies, estimates and assumptions. As a result, the CEO pay ratios reported by other companies, which may have employed other permitted methodologies or assumptions and which may have a significantly different work force structure from ours, are likely not comparable to our CEO pay ratio.        2022 Proxy Statement      88    97   Proposal 3—Ratification of the Appointment of Ernst & Young LLP as Our Independent Registered Public Accounting Firm for the Fiscal Year Ending September 30, 20222023 Under its charter, the Audit Committee of the Board has direct responsibility for the appointment, compensation, retention, oversight, and termination of the independent registered public accounting firm engaged to audit the Company’s financial statements.

We will bear the entire cost of solicitation of proxies, including preparation, assembly, printing, and mailing of the Notice or a full set of the proxy materials (including the Proxy Statement, the 20212022 Annual Report and proxy card with postage-paid envelope), as applicable, and any additional information furnished to stockholders. We have retained Okapi Partners LLC to assist with the solicitation of proxies for a fee not to exceed $40,000,$20,000, plus reimbursement of reasonable out-of-pocket expenses. Original solicitation of proxies may be supplemented by electronic means, mail, facsimile, telephone, or personal solicitation by our directors, officers, or other employees. No additional compensation will be paid to our directors, officers, or other employees for such services. Copies of solicitation materials will be furnished to brokers, banks, and other nominees holding shares of voting stock beneficially owned by others to forward to such beneficial owners. In accordance with SEC rules, we may reimburse brokers, banks, and other nominees for their reasonable costs of forwarding proxy materials to beneficial owners. Are you “householding” for stockholders sharing the same address? The SEC has adopted rules that permit companies and intermediaries, such as brokers, to satisfy delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement or annual report, as applicable, addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially provides extra convenience for stockholders and cost savings for companies. Evoqua has not instituted householding for stockholders of record. However, certain brokerage firms may have instituted householding for beneficial owners of shares of Evoqua’s common stock held through brokerage firms. If your household has multiple accounts holding shares of Evoqua’s common stock, you may already have received a householding notification from your broker. Please contact your broker directly if you have any questions or require additional copies of this Proxy Statement, the Notice, or the 20212022 Annual Report. The broker will arrange for delivery of a separate copy of these materials promptly upon your request. Evoqua stockholders may decide at any time to revoke a decision to household, and thereby receive multiple copies.

The Company reports its financial results in accordance with GAAP. However, management believes that certain non-GAAP financial measures provide users of the Company’s financial information with additional useful information in evaluating operating performance. The presentation of this additional information is not meant to be considered in isolation or as a substitute for GAAP measures. FISCAL YEAR 2021 AIPEBITDA and Adjusted EBITDA Evoqua Global Adjusted EBITDA Evoqua GlobalEBITDA, which is a non-GAAP financial measure, is defined as earnings before interest, taxes, depreciation and amortization expense. 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. For the periods presented, other gains, losses, and expenses include the following: i.   impact of foreign exchange gains and losses; ii.   net expense reduction related to the remediation of manufacturing defects caused by a third-party vendor for which partial restitution was received; iii.  charges incurred by the Company related to product rationalization in its electrochlorination business; iv. amounts related to the prior year sale of the Memcor® product line; v.  expenses incurred by the Company as a result of the COVID-19 pandemic, including additional charges for personal protective equipment, increased costs for facility sanitization and one-time payments to certain employees; vi. legal fees incurred in excess of amounts covered by the Company’s insurance related to the Securities Litigation and SEC investigation; and vii.  loss on divestiture of the Lange containment system, geomembrane and geosynthetic liner product line (“Lange Product Line”). We also adjust for the impacts of acquisitions and divestitures so that payout levels are not artificially inflated or impaired by factors unrelated to the ongoing operation of the business. For purposes of the fiscal year 2020 AIP, we also included an adjustment to reflect the payment of fiscal year 2020 AIP bonuses to Executive Leadership Team members in cash, rather than in RSUs. 2022 Proxy Statement A-1 ISS Segment Adjusted EBITDA We calculate Segment Adjusted EBITDA in the ISS Segment as ISS Segment operating profit (as determined in accordance with GAAP) plus add-backs for depreciation and amortization, restructuring and related business transformation costs, transaction costs and other gains, losses, and expenses. Other losses, (gains), and expenses, as discussed above, distinct to our ISS Segment include a loss on the divestiture of the Lange Product Line. We also adjust for the impacts of acquisitions and divestitures so that payout levels are not artificially inflated or impaired by factors unrelated to the ongoing operation of the business. For purposes of the fiscal year 2020 AIP, we also included an adjustment to reflect the payment of fiscal year 2020 AIP bonuses to Executive Leadership Team members in cash, rather than in RSUs. APT Segment Adjusted EBITDA We calculate Segment Adjusted EBITDA in the APT Segment as APT Segment operating profit (as determined in accordance with GAAP) plus add-backs for depreciation and amortization, restructuring and related business transformation costs, transaction costs and other gains, losses, and expenses. Other losses, (gains), and expenses, as discussed above, distinct to our APT segment include the following: i.  trailing costs from the sale of the Memcor® product line; ii.  net pre-tax benefit on the sale of the Memcor product line; iii. remediation of manufacturing defects; and iv.   product rationalization in the electrochlorination business We also adjust for the impacts of acquisitions and divestitures so that payout levels are not artificially inflated or impaired by factors unrelated to the ongoing operation of the business. For purposes of the fiscal year 2020 AIP, we also included an adjustment to reflect the payment of fiscal year 2020 AIP bonuses to Executive Leadership Team members in cash, rather than in RSUs. Evoqua Global Adjusted Free Cash Flow We calculate Evoqua Global Adjusted Free Cash Flow as net cash from operating activities (as determined in accordance with GAAP and as reported in our Statement of Cash Flows) less capital expenditures as well as adjustments for other significant items that impact current results which management believes are not related to our ongoing operations and performance. Our definition of free cash flow does not consider certain non-discretionary cash payments, such as debt. FISCAL YEAR 2022 LTIP Cumulative Organic Revenue Growth ($) Cumulative organic revenue growth dollars means the increase in revenue over the performance period, adjusted for acquisitions and divestitures. Average Adjusted EBITDA Margin (%) Average adjusted EBITDA margin means the average of Earnings Before Interest, Taxes, Depreciation, and Amortization (EBITDA), as adjusted to exclude certain other items, including restructuring costs, stock-based compensation, transaction costs, acquisitions and divestitures and certain other gains or losses for years one, two, and three, divided by revenue for years one, two, and three. A-2 GAAP TO NON-GAAP RECONCILIATIONS Adjusted EBITDA 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. Adjusted EBITDA is one of the primary metrics used by management to evaluate the financial performance of our business. 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 relating toregarding 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 organic 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 as a supplement to segment income from operations and segment revenue 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. 2023 Proxy Statement A-1 EBITDA and Adjusted EBITDA should not be considered a substitutesubstitutes 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 included below should be carefully evaluated. 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, adjusted EBITDA may not be comparable to similarly titled measures used by other companies in our industry or across different industries.industries may calculate adjusted EBITDA differently. 2022 Proxy Statement A-3 The following is a reconciliation of our net income to adjusted EBITDA:   ($ in millions)    FY2021      FY2020      FY2022        FY2021   Net income    $ 51.7      $ 114.4          $ 72.3        $ 51.7 Income tax expense      10.1        7.4       Income tax (benefit) expense      (3.0 )         10.1 Interest expense      37.5        46.6            34.7          37.5 Operating profit    $ 99.3      $ 168.4          $ 104.0        $ 99.3 Depreciation and amortization      113.7        107.3            127.6          113.7 EBITDA    $ 213.0      $ 275.7          $ 231.6        $ 213.0 Restructuring and related business transformation costs(a)      11.3 (1)       17.4(5)        6.4          11.3   Share-based compensation      17.7 (2)       10.5(6)   Purchase accounting adjustment costs(b)      4.2          —   Transaction costs      1.6 (3)       1.9(7)   Share-based compensation(c)      23.5          17.7   Other (gains), losses and expenses      7.3 (4)       (65.9)(8)   Transaction costs(d)      8.1          1.6   Other losses (gains) and expenses(e)      23.9          7.3   Adjusted EBITDA    $ 250.9      $ 239.6          $ 297.7        $ 250.9 Revenue    $ 1,464.4      $ 1,429.5       Adjusted EBITDA as a % of Revenue      17.1 %       16.8%        (1)(a) Primarily comprisedRestructuring and related business transformation costs Adjusted EBITDA is calculated prior to considering certain restructuring or business transformation events.

We have included in this Proxy Statement information about the Company’s revenue growth in fiscal years 2018 through 2022. To supplement this information, we provide below details of our historical revenue growth by driver. COMPONENTS OF OUR REVENUE Our revenue is another metrica function of sales volumes and selling prices. We report revenue by segment and by source which includes revenue from product sales (capital and aftermarket) and revenue from service. Revenue is used by management to evaluate the performance of our business. “Organic revenue”Revenue growth is primarily related to organic and inorganic factors. Organic revenue growth, as a component of revenue growth, is defined as period over period revenue growth excluding the impact of foreign currency translation and inorganic revenue. Inorganic revenue represents(i) the impact from acquisitions and divestitures during the first 12 months following the closing of the acquisition or divestiture.divestiture, which we refer to as inorganic impact, and (ii) the impact of foreign currency translation. Divestitures include sales of insignificant portions of our business that did not meet the criteria for classification as a discontinued operation. 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.. We exclude the effect of foreign currency translation from organic salesrevenue growth 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 during the first 12 months following the closing of the acquisition or divestiture 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. A-6 We have not presented a quantitative reconciliation of the forward-looking non-GAAP financial measure organic revenue to its most directly comparable GAAP financial measure, total revenue, because it is impractical to forecast certain items without unreasonable efforts due to the uncertainty and inherent difficulty of predicting the occurrence and financial impact of, and the periods in which, such items, including foreign exchange impact and acquisitions or divestitures, may be recognized. For the same reasons, we are unable to address the probable significance of the unavailable information, which could be material to future results.

For the periods presented, other gains, losses, and expenses include the following:   i.   impact of foreign exchange gains and losses; ii.   charges incurred by the Company related to product rationalization in its electrochlorination business; iii.  amounts related to the sale of the Memcor product line; iv.  expenses incurred by the Company as a result of the COVID-19 pandemic, including additional charges for personal protective equipment, increased costs for facility sanitization and one-time payments to certain employees; v.   legal fees incurred in excess of amounts covered by the Company’s insurance related to securities litigation and SEC investigation matters; and vi.  loss on divestiture of the Lange Product Line. We also adjust for the impacts of acquisitions and divestitures so that payout levels are not artificially inflated or impaired by factors unrelated to the ongoing operation of the business. ISS Segment Adjusted EBITDA We calculate Segment Adjusted EBITDA in the ISS Segment as ISS Segment operating profit (as determined in accordance with GAAP) plus add-backs for depreciation and amortization, restructuring and related business transformation costs, purchase accounting adjustment costs, transaction costs and other gains, losses, and expenses. Other losses, (gains), and expenses, as discussed above, distinct to our ISS Segment include a loss on the divestiture of the Lange Product Line. We also adjust for the impacts of acquisitions and divestitures so that payout levels are not artificially inflated or impaired by factors unrelated to the ongoing operation of the business. 2023 Proxy Statement C-1 APT Segment Adjusted EBITDA We calculate Segment Adjusted EBITDA in the APT Segment as APT Segment operating profit (as determined in accordance with GAAP) plus add-backs for depreciation and amortization, restructuring and related business transformation costs, transaction costs and other gains, losses, and expenses. Other losses, (gains), and expenses, as discussed above, distinct to our APT segment include the following: i.   trailing costs from the sale of the Memcor® product line; and ii.  product rationalization in the electrochlorination business We also adjust for the impacts of acquisitions and divestitures so that payout levels are not artificially inflated or impaired by factors unrelated to the ongoing operation of the business. Evoqua Global Adjusted Free Cash Flow We calculate Evoqua Global Adjusted Free Cash Flow as net cash from operating activities (as determined in accordance with GAAP and as reported in our Statement of Cash Flows) less capital expenditures as well as adjustments for other significant items that impact current results which management believes are not related to our ongoing operations and performance. Our definition of free cash flow does not consider certain non-discretionary cash payments, such as debt.                 A-8C-2      Appendix BD 2021 Special AwardsTSR Peer Group S&P GLOBAL WATER INDEX — U.S. COMPANIES   1.
