OUR COMMITMENT TO ENVIRONMENTAL, SOCIAL RESPONSIBILITY AND GOVERNANCE PRINCIPLES

We consider environmental, social responsibility and governance, or ESG, principles fundamental to our corporate strategy and values. Integration of these principles into our daily operations emphasizes our belief that “how” a company operates is just as important as “what” a company does. We have developed a cross-functional approach that supports and drives our ESG strategy, principles and reporting, which includes the direct involvement and participation of our executive leadership team and oversight from our Board.

Reliably delivering safe, clean and affordable water and wastewater service to customers has been fundamental to our business for decades. We seek to make a positive, sustainable impact in many communities by serving them with our diverse and skilled employees with a goal to meet or exceed service expectations.

Our ESG-focused vision and values drive our company strategy, which is centered on five central themes:



		· Our number one focus is the safety of our employees and customers. · Safety is a core value.

		· We strive to maintain an inclusive and equitable environment where our employees positively impact and reflect the communities we serve. · By investing in the development of our employees, we seek to create a workplace where they can reach their fullest potential while feeling safe, respected and included.

		· We believe that through growth, we can invest in creating more jobs, enhanced training and benefits, and improved infrastructure, in the communities we serve. · Our growing and geographically diverse customer base allows us to invest more in our systems while maintaining customer affordability.

		We are committed to providing a superior customer experience based on the belief that every community should be stronger because we are there.

		Our operational excellence strategy helps us to find better and more efficient ways to do business and provide safe, clean, reliable, and affordable services for our customers.

We have received a number of recognitions for demonstrating ESG leadership. For example, we have been recognized on the 2023 Bloomberg Gender-Equality Index for the fifth consecutive year, we were ranked 18th on Barron’s 100 Most Sustainable U.S. Companies 2023 List, and we have earned the U.S. Environmental Protection Agency’s WaterSense^® Excellence Award. For our efforts in hiring and supporting U.S. military veterans, we were honored as a 2023 VETS Indexes 3-Star Employer and have earned the 2024 Military Friendly^® Gold Employer designation.

Highlights of our sustained ESG efforts in 2023 include:

Issuance of our seventh biennial Sustainability Report as well as our ESG Data Summary

Issuance of our third annual inclusion, diversity and equity, or ID&E, report

Independent assurance as to scope 1 and 2 greenhouse gas emissions, and disclosure of estimated material scope 3 emissions

Continued alignment of metrics in our cash-based annual performance plan, or APP, with our ESG principles

AMERICAN WATER | 2024 PROXY STATEMENT

The internet and telephone voting for shareholders of record will close at 11:59 p.m., Eastern Time, on Tuesday, May 14, 2024.

Your signed proxy card, or the proxy you grant via the Internet or by telephone, will be voted in accordance with your instructions. If you return a signed proxy card or grant a proxy via the Internet or by telephone, but do not indicate how you wish your shares to be voted, your shares will be voted:

“FOR” the election of each of the Board’s nine director nominees

“FOR” the approval, on an advisory basis, of the compensation of our named executive officers

“FOR” the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for 2024

In the absence of instructions to the contrary, proxies will be voted in accordance with the judgment and discretion of the person exercising the proxy on any

other matter properly presented at the meeting and any adjournment or postponement thereof.

If you wish to vote your shares virtually at the meeting, you may vote online during the meeting at www.virtualshareholdermeeting.com/AWK2024, entering your 16-digit control number, and following the on-screen instructions.

If you received more than one proxy card or Notice of Availability, your shares are likely held in more than one account, registered in different names or registered with different addresses. You must separately vote the shares shown on each proxy card or Notice of Availability that you receive in order for all of your shares to be voted at the meeting. For more information regarding the Notice of Availability, please see “Communications, Shareholder Proposals and Company Information—Delivering Proxy Materials Through Electronic Means” on page 69 of this proxy statement.

HOW TO VOTE SHARES HELD IN STREET NAME

If you hold shares through a brokerage firm, trustee, bank, or other financial intermediary or nominee, which is known as holding shares in “street name,” you will receive a voting instruction form from that broker, trustee, bank or other financial intermediary or nominee, each of which we refer to as an “intermediary.” The form will explain how to direct the voting of your shares through the intermediary, which may include the ability to provide voting instructions via the Internet or by telephone.

If your shares are held in street name and you want to vote on Proposals 1 or 2, you MUST indicate how you wish your shares to be voted. The broker will vote shares held by you in street name in accordance with your voting instructions, as indicated on your signed voting instruction form or by the instructions you provide via the Internet or by telephone. Absent such instructions, NYSE rules prohibit a broker from exercising discretion to cast a vote with respect to your shares. In that case, a proxy submitted by the broker with respect to your shares would indicate that the broker is unable to cast a vote with respect to the matter, which is commonly referred to as a “broker non-vote.”

Under NYSE rules, Proposal 3 is considered a “routine matter,” and thus a broker would be permitted in its

discretion to cast a vote on that proposal as to your shares in the event that you do not provide the broker with voting instructions. Accordingly, if your shares are held in street name, it is important that you provide voting instructions to the intermediary so that your vote will be counted.

If you received more than one voting instruction form or Notice of Availability, your shares are likely registered in different names or with different addresses or are in more than one account. You must separately follow the foregoing voting procedures for each voting instruction form or Notice of Availability that you receive in order for all of your shares to be voted at the meeting.

If you hold shares in street name and wish to vote your shares virtually at the meeting, you may vote online during the meeting by visiting www.virtualshareholdermeeting.com/AWK2024, entering your 16-digit control number, and following the on-screen instructions. The availability of online voting may depend on your intermediary’s specific voting procedures. Please contact your intermediary for information.

AMERICAN WATER | 2024 PROXY STATEMENT

BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

THE BOARD OF DIRECTORS

As of the date of this proxy statement, the Board is comprised of nine members, consisting of eight independent directors and M. Susan Hardwick, our President and Chief Executive Officer.

The Board held 10 meetings during 2023. During the period in 2023 for which each incumbent director served as such, each such director attended at least 75 percent of the combined number of Board meetings and meetings of the Board committees on which such director served. The average attendance during 2023 for all Board members was 96.1 percent.

The Board has adopted an attendance policy, set forth in our Corporate Governance Guidelines, under which attendance, whether in person or by remote

communication, is expected at all Board and committee meetings, except for absences previously excused by the Board Chair or the Chair of the Nominating Committee, due to extraordinary circumstances. All members of the Board are expected to attend the annual meeting of shareholders, except for absences due to unavoidable or extenuating circumstances. All of the directors then on the Board virtually attended the 2023 annual meeting of shareholders.

At most regularly scheduled meetings, the Board meets in executive session, without members of management present. Our independent, non-executive Board Chair presides over these sessions.

BOARD REVIEW OF RELATED PERSON TRANSACTIONS

The Board has approved a Related Person Transaction Policy, which serves to identify, review and approve transactions involving related persons. This policy supplements our Code of Ethics by prohibiting transactions with related persons unless specifically exempt or prior written approval is granted as discussed below. Related person transactions are non-exempt transactions, relationships or arrangements in excess of $120,000 in which American Water or any subsidiary was or is to be a participant and a related person had or will have a direct or indirect material interest. For purposes of this policy, a “related person” is:

an executive officer or director of the Company;

a beneficial owner of more than five percent of our common stock; or

an immediate family member (as defined by the policy) of any of the foregoing.

Approval of a related person transaction may only be granted in writing in advance by the disinterested members of either the Board or the Audit, Finance and

Risk Committee. Before any related person transaction is approved, the following factors, among others, are to be considered:

the purpose, and the potential benefits to American Water, of the transaction;

the related person’s interest in the transaction;

the dollar value of the transaction or the related person’s interest in the transaction without regard to the amount of any profit or loss;

whether the transaction is to be undertaken in the ordinary course of business of American Water; and

whether the transaction is on terms more favorable to American Water than a transaction with an unrelated third party.

Approval of a related person transaction under the policy will be granted only if it is determined that, under all of the circumstances, the transaction is in the best interests of American Water and only so long as those interests outweigh any negative effects that may arise from permitting the transaction to occur.

BOARD LEADERSHIP STRUCTURE

Since February 2, 2022, Ms. Hardwick has served as our President and Chief Executive Officer and a member of our Board. Mr. Kurz has served as our Board Chair since May 11, 2018.

In accordance with our Corporate Governance Guidelines, the Board Chair is an independent

director. We believe that the oversight function of a board of directors is enhanced when an independent director, serving as board chair, is in a position to set the agenda for, and preside over, meetings of the board of directors. We also believe that our leadership structure enhances the active participation of our independent directors.

AMERICAN WATER | 2024 PROXY STATEMENT

LOGO

The Board Chair is responsible for:

setting the agenda for meetings of the Board, and presiding over Board meetings at which the Board Chair is present;

coordinating the work of the Board committees;

overseeing the distribution of materials by our Secretary to the members of the Board;

serving as the independent director primarily responsible for Board consultations and communications between the Board and shareholders; and

performing such other duties as the Board may, from time to time, require to assist it in the fulfillment of its duties.

If the Board Chair ceases to be an independent director, the Board shall select another Board Chair from among the members of the Board who are determined by the Board at that time to be independent directors. The Board Chair is selected, and may be removed from that position at any time, by a majority of the members of the Board.

BOARD ROLE IN RISK OVERSIGHT

One of the responsibilities of the Board is the oversight of our risk management activities, which is discharged by the Board as well as through the Audit, Finance and Risk Committee, the ED&CC and the SETO Committee. In discharging this responsibility, the Board and these committees, with the assistance of management, monitor and evaluate our major enterprise risks and oversee and monitor the design and implementation of guidelines and programs to manage these risks.

Our management has overall responsibility for conducting risk assessments and risk management strategy and programs. Our Enterprise Risk

Management Committee, consisting of various Company executives, as well as certain functional and business unit employees and leaders, oversees enterprise risk management activities. The Enterprise Risk Management Committee meets at least four times a year. The Enterprise Risk Management Committee’s areas of focus include competitive, economic, operational (including physical security and cybersecurity), financial (including accounting, internal audit, credit, liquidity and tax), legal, compliance, regulatory, health, safety and environmental, political and reputational risks.

Audit, Finance and Risk Committee Role

The Audit, Finance and Risk Committee is responsible for assisting the Board in overseeing the Company’s accounting and disclosure controls, the design and performance of the internal audit, ethics and compliance functions, and the enterprise risk management process, including risk assessments and risk management strategy. The Audit, Finance and Risk Committee also has direct authority over the Company’s independent registered public accounting firm.

In performing these responsibilities, the Audit, Finance and Risk Committee reviews, at least annually, with management our major financial and operational risk

exposures, including any risk concentrations and risk interrelationships, the magnitude and the likelihood of occurrence of risk, and management’s activities to monitor and control these exposures. This committee also reviews our major financial risks, including credit, liquidity, market and funding risks. The Audit, Finance and Risk Committee coordinates oversight of operational risk management, including with respect to cybersecurity risks, with the SETO Committee. The Audit, Finance and Risk Committee also oversees our insurance risk management policies and programs and makes recommendations to the Board regarding the structure and renewal of our directors’ and officers’ liability insurance program.

Management conducts and presents to the ED&CC for its review an annual risk assessment of our executive compensation, with a particular focus on performance-based compensation. For 2023, this risk assessment was directly supported by our internal enterprise risk management function and our Enterprise Risk Management Committee, and included an in-depth review of the risks associated with our compensation and variable pay programs, employing a risk identification methodology that is used throughout the business. In May 2023, an update of this risk assessment for 2022 was reviewed with the ED&CC. This assessment sought to identify whether features of our compensation policies or practices are reasonably likely to have a material adverse effect on the company.

The risk assessment conducted by management found that our existing short-term and long-term compensation is coupled with compensation design elements and other controls that discourage decision-making focused solely on compensatory consequences. These design elements and controls include, among other things:

use of both financial and non-financial metrics that avoids over-emphasis on a single metric;

oversight and approval of compensation decisions by the ED&CC and its retention of an independent compensation consultant;

centralized data reporting platforms which permit information to be collected, reviewed and verified in compliance with internal policies;

transparency as to the design, management and execution of our executive compensation program, including disclosures in our proxy statement and other required SEC filings;

significant internal review of financial and operational performance metrics and performance reviews during the year regarding the operation of our business, as well as an audit of our financial statements by our independent registered public accounting firm; and

a compensation recovery policy that at the time required repayment of incentive compensation in the event of a material restatement of our financial statements under specific circumstances.

On the basis of management’s review of our executive compensation programs, management concluded, and advised the ED&CC, that no significant risks have been identified and that it does not believe it is reasonably likely that the compensation policies, practices or programs could have a material adverse effect on American Water. It is currently anticipated that the risk assessment for 2023 will be completed and reviewed with the ED&CC in May 2024.

SETO Committee Role

The SETO Committee reviews and monitors operational risk exposure and risk mitigation strategies with the Audit, Finance and Risk Committee and the Board. In performing these responsibilities, the SETO Committee reviews management’s processes for assessing business continuity risks and developing related contingency planning. The SETO Committee also reviews physical and cybersecurity

preparedness and threat assessments, is updated on emerging issues and our related responses and initiatives, and coordinates with the Audit, Finance and Risk Committee and the Board on matters related to cybersecurity risk. The SETO Committee reviewed and recommended the inclusion of the description of our cybersecurity program in our 2023 Form 10-K.

BOARD ROLE IN SUCCESSION PLANNING

The Corporate Governance Guidelines provide that a primary responsibility of the Board is planning for the succession of our CEO and other executive officers. The goal of our succession planning process is to identify executive talent at the Company and provide for continuity of effective leadership that can fulfill the long-term requirements of our business. The Corporate

Governance Guidelines contemplate a collaborative effort between the Board (and certain of its committees) and the CEO; however, the Board retains full responsibility for the selection of the CEO.

Specifically, the Corporate Governance Guidelines provide that the CEO annually submits to the Board for

AMERICAN WATER | 2024 PROXY STATEMENT

LOGO

its review a succession plan for the CEO and other executive officers. The succession plan includes a determination of key competencies and desired experiences for the particular role, an identification and assessment of internal candidates, development plans for internal candidates and, as appropriate, identification of external candidates. The criteria used to assess potential CEO candidates are formulated by the Board based on the Company’s business strategies, and include the candidates’ experience, as well as strategic and leadership qualities. The Board’s deliberation on CEO succession shall include an emergency succession plan which addresses temporary delegation of authority if an unforeseen event such as death or disability occurs that prevents the CEO from continuing to fulfill the role. The Board may review executive development and succession planning more frequently as it deems appropriate.

Consistent with its responsibilities as described in this section, the Board has delegated the day-to-day responsibility for the process of providing a slate of CEO succession candidates for consideration by the Board to the Nominating Committee, with input from the Board Chair and the current CEO. The Board also has delegated authority to the ED&CC to collaborate with the CEO to ensure that processes are in place for succession planning and development with respect to other executive officers.

As a practical matter, consideration of executive succession planning (especially for the CEO role) occurs throughout the year at Board meetings and involves regular interaction between and among the Board, the President and Chief Executive Officer, the Executive Vice President, Chief Human Resources Officer, and other members of management, as appropriate.

LIMITATIONS ON ADDITIONAL BOARD SERVICE

The Board’s Corporate Governance Guidelines limit the service of Board members as directors of other public companies. Commonly referred to as “overboarding” provisions, the primary purpose of these limitations is to ensure that each director can devote sufficient time to perform their duties as a member of the Board.

Under these provisions, a director may not serve on the board of directors of more than four public companies, including American Water, and a director who is an executive officer of a public company, including American Water, may not serve on the board of directors of more than two public companies, including American Water. A director may not serve on the audit committee of more than two public

companies, excluding American Water, without the prior approval of the Nominating Committee.

Also, for any potential board service not prohibited by these limitations, directors are required to advise and obtain the approval of the Nominating Committee chair in advance of accepting an invitation to serve on a for-profit board. Prior to approving such service, the Nominating Committee chair will review the proposed relationship for potential conflicts of interest and time demands, considering such facts as the chair deems relevant, including industry or operations of the other company and whether service on a greater number of boards would impair the director’s ability to serve effectively on the Board.

BOARD REFRESHMENT AND DIRECTOR TENURE

The following graphic depicts the tenure of our Board nominees as of the date of this proxy statement:

LOGO

LOGO

AMERICAN WATER | 2024 PROXY STATEMENT

As represented by the director tenure graphic above and evidenced by our actual Board refreshment over the past few years, we seek to maintain a continual balance of directors with historical and institutional knowledge and experience coupled with new directors who have more recently joined the Board. While we believe the current and proposed size and composition of the Board are appropriate, the Board continually devotes substantive attention and focus on Board succession planning and activities to meet the Board’s future needs.

Our Corporate Governance Guidelines do not impose term limits on the service of our directors. The Nominating Committee reviews annually each director’s continuation on the Board, which allows each director the opportunity to confirm their desire to continue as a director and provides the Board an opportunity to replace directors who no longer wish to remain on the Board. Also, the Nominating Committee

periodically assesses the quality and efficacy of our Board tenure and refreshment policies, including based on feedback received from our shareholder outreach program (described in more detail below).

Our Corporate Governance Guidelines generally restrict a non-employee director who has reached their 75th birthday prior to the date of our annual meeting of shareholders from being nominated for re-election to the Board. However, the Board may, in special circumstances and where deemed in the best interests of the Company, grant an exception to this policy on an annual basis. The Board must determine to make a special exception prior to each ensuing term of a director for which the special exception will be applicable. There are no director nominees standing for election at the annual meeting who are 75 years of age or older.

SHAREHOLDER OUTREACH

During 2023, our Investor Relations team, together with key executives and management, engaged with over 250 investors. In addition, our Corporate Secretary and Investor Relations teams jointly led a shareholder outreach program focused on corporate governance, executive compensation, ESG and sustainability, ID&E, shareholder disclosure and related topics. Through this outreach program, now in its tenth consecutive year and held both during and after proxy season, shareholders who beneficially owned, in the aggregate, approximately 52 percent of our common stock, as well as leading proxy advisory firms, were contacted. The purpose of this outreach program is to better identify and understand the relevant topics that were most important to our shareholders. Through these sessions, we:

discussed topics of interest to our shareholders;

solicited shareholder viewpoints;

conveyed our views on those topics; and

gained a better understanding of areas of mutual consensus.

We received overall positive feedback regarding, among other things: our corporate governance framework, our Board composition, our proxy statement disclosures, our compensation practices, our commitment to ESG, including racial equity and justice, and our political contribution and lobbying governance and disclosure. Also, shareholders expressed appreciation for our willingness to seek their views, and more importantly, the desire to establish an ongoing dialogue with them. Shareholders also encouraged us to continue to make voluntary disclosures, including summaries of our key initiatives that will help them better understand our policies, procedures and how we run the business. The input and insight gleaned from our shareholder outreach program is shared with management and our Board.

We intend to continue to engage regularly with shareholders and proxy advisory firms to solicit their input, and we give careful consideration to the feedback we receive. We also use this outreach to consider meaningful avenues to respond to appropriate suggestions for further enhancement to our corporate governance standards and practices.

GOVERNANCE POLICIES AND PROCEDURES

Our Code of Ethics applies to our directors, officers and employees and is designed to promote, among other things:

honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest in personal and professional relationships, and deter wrongdoing or even perceptions of wrongdoing;

full, fair, accurate, timely and understandable disclosures in periodic reports we are required to file;

accountability for adhering to the Code of Ethics; and

compliance with applicable governmental laws, rules and regulations.

Our Code of Ethics provides for the prompt internal reporting of violations to an array of appropriate persons and confidential treatment of the reporting person, to the extent possible, during a compliance investigation. We intend to satisfy the disclosure requirements regarding any amendment to, or waiver from, a provision of the Code of Ethics that applies to our principal executive officer, principal financial officer, or principal accounting officer or controller (or persons performing similar functions) by making disclosures concerning such matters available on the Investor Relations page of our website.

We have also adopted an Anti-Corruption & Anti-Bribery Policy that reinforces our commitment to working ethically and maintaining the highest level of integrity when conducting business on behalf of the Company. This policy promotes truthful and transparent conduct in our interactions with our business partners, governmental agencies and government officials. We have a long-standing commitment to compliance with all applicable anti-corruption laws, and bribes, kickbacks, and other similar payments to or from third-parties are prohibited.

Our Corporate Governance Guidelines set out principles by which the Board will operate and execute its responsibilities in accordance with our Restated Certificate of Incorporation, our Amended and Restated Bylaws, the listing standards of the NYSE, and applicable laws.

Current copies of our Code of Ethics, Anti-Corruption & Anti-Bribery Policy and Corporate Governance Guidelines are available on our Investor Relations website at ir.amwater.com and can also be obtained by sending us a written request. See “Communications, Shareholder Proposals and Company Information—Contacting Us or Our Transfer Agent” on page 70 of this proxy statement.

PROXY ACCESS

Our Amended and Restated Bylaws include a proxy access provision pursuant to which any eligible shareholder, or eligible group of up to 20 shareholders, owning three percent or more of our common stock continuously for a three-year period and through the date of the next annual meeting of shareholders may, subject to certain limitations and

conditions, nominate and include in our proxy materials for that annual meeting of shareholders, a number of director nominees not to exceed the greater of (a) two directors or (b) 20 percent of the directors then serving on the Board (rounded down to the nearest whole number).

POLITICAL CONTRIBUTION POLICY

As a company whose regulated operations can be significantly impacted by public policies, we participate responsibly in the political process and make reasonable political contributions consistent with all applicable laws and reporting requirements. We also hold memberships in a variety of industry, trade and business associations, which enable us to understand the views of others and obtain feedback on our positions.

As part of our commitment to good governance principles and transparency, we maintain a Political Contribution Policy that requires that our political contributions, which we define as direct contributions or expenditures (in cash or in kind) to a political party, a candidate for an elected office or a candidate’s political campaign, or a political action committee, or PAC, (subject to the exclusions referenced below) be made only:

by the American Water Works Company, Inc. Employee Federal PAC, referred to as the Federal PAC; or

LOGO

AMERICAN WATER | 2024 PROXY STATEMENT

to, or through, a PAC sponsored by or associated with one of our subsidiaries or lines of business, referred to as a Subsidiary PAC.

Political contributions, as defined under this policy, do not include amounts spent in connection with a core business function, such as a water or wastewater system acquisition, defense of a condemnation action filed against us, or other activities that impact or affect the operation of our business, unless made to support a political party, a candidate for an elected office or a political campaign. Also, a payment to a trade association or tax-exempt organization (other than a PAC, a Section 527 organization, or a similar entity) is not a political contribution under this policy, even if any portion of the payment is used for political purposes.

All political contributions by the Company must be approved in advance by our CEO. Political contributions by the Company’s subsidiaries must first be approved by the subsidiary’s or line of business’s president, or similar officer. This pre-approval requirement does not apply to contributions by the Federal PAC or a Subsidiary PAC, which are governed by the PAC’s own charter, policies and procedures. Our Political Contribution Policy does not regulate or apply to our employees’ own political contributions.

Since 2019, we have disclosed annually on our website, within 180 days after the end of the preceding fiscal year, the following information regarding our political contributions:

the payor, recipient, date and amount of each direct political contribution (as defined under the

Political Contribution Policy) made, and the title of the person approving it;

the payor, recipient, date and amount of each political contribution made by the Federal PAC and each Subsidiary PAC; and

the payor, recipient and amount of each payment made to a trade association or tax-exempt organization (including Section 501(c)(4) organizations) during the last fiscal year, which, individually or in the aggregate, exceeded $50,000, if the association or organization provided a written statement that some or all of our payments were used for non-deductible political, electioneering or lobbying purposes, as well as the amount reported by the association or organization as attributable to these non-deductible activities.

Our governance and disclosure efforts regarding political contributions continue to be recognized by the Center for Political Accountability’s CPA-Zicklin Index, which for 2023 placed us in the second quartile among all of the S&P 500 companies.

The Nominating Committee reviews and evaluates the efficacy of our Political Contribution Policy at least annually and reviews and recommends to the Board for approval in advance the public disclosures required by the policy. The policy and our political contribution disclosures are available through our Investor Relations website at ir.amwater.com.

LOBBYING EXPENDITURES

We value our relationships with government officials and our interactions with them comply with applicable federal, state and local laws, regulations and rules. These rules are often complex and vary from state to state. However, we believe it is an important and necessary part of our mission to provide safe, clean, reliable and affordable water and wastewater services to our customers to engage in the public policy arena. For these reasons, we do, from time to time, engage in lobbying activities, which we define generally as communications with government officials, legislators, regulators, executive branch officials or members of their staff.

We publicly disclose on our website, within 180 days after the end of each fiscal year, the amount of aggregate lobbying expenditures (as defined under applicable state or federal law and to the extent required to be reported to applicable election commissions). This reported amount includes all expenditures made during periods of time required to be reported for the last fiscal or calendar year by the Company or any subsidiary, and it may include expenditures for periods of time other than such year, as well as other exclusions and/or limitations provided for under state or federal election law. Members of senior management report annually to the Board on our lobbying activities to provide oversight for these activities.

PROPOSAL 1

ELECTION OF DIRECTORS

EXPLANATION OF THE PROPOSAL

In accordance with our Restated Certificate of Incorporation and Amended and Restated Bylaws, the number of directors is fixed from time to time by the Board. On February 14, 2024, the size of the Board was reduced from 10 to nine after the resignation of Admiral James G. Stavridis from the Board effective February 12, 2024, and nine persons have been named as director nominees for election at the 2024 annual meeting.

On the recommendation of the Nominating Committee, the Board has nominated for election to the Board the following persons:

Jeffrey N. Edwards

Martha Clark Goss

M. Susan Hardwick

Kimberly J. Harris

Laurie P. Havanec

Julia L. Johnson

Patricia L. Kampling

Karl F. Kurz

Michael L. Marberry

Each of these nominees is currently a member of the Board. If elected, each nominee would hold office until the date of the 2025 annual meeting of shareholders, or until their successor is elected and qualified, or until their earlier death, resignation or removal. Proxies may not be voted with respect to more than these nine nominees.

Each director nominee identified in this proxy statement has confirmed that the director is willing and able to serve as a director, if elected. Should any of the nominees, prior to the meeting, become unable to serve as a director for any reason, the Board may either reduce the number of directors to be elected or select another nominee recommended by the Nominating Committee. If another nominee is selected, all proxies will be voted for the substitute nominee.

In accordance with our Amended and Restated Bylaws and our Corporate Governance Guidelines, prior to the meeting, each incumbent director nominee will submit a contingent resignation in writing to the Board Chair or the Secretary of American Water. The resignation becomes effective only if the director fails to receive a sufficient number of votes for re-election at the meeting, assuming a quorum is present and the Board accepts the resignation. In an uncontested election of directors, if any incumbent director nominated for re-election does not receive the affirmative vote of at least the majority of the votes cast at any meeting for the election of directors at which a quorum is present, the Nominating Committee will make a recommendation to the Board on whether to accept or reject such tendered resignation, or whether other action should be taken. The Board will act on the tendered resignation, taking into account the Nominating Committee’s recommendation, and publicly disclose, by a press release, a filing with the SEC, or other broadly disseminated means of communication, its decision regarding the tendered resignation and the rationale behind the decision of the Board within 90 days from the date of the certification of the election results.

With respect to a tendered resignation, each of the Nominating Committee, in making its recommendation, and the Board, in making its decision, may consider any factors or other information that it considers appropriate and relevant. The director who tenders their resignation will not participate in the recommendation of the Nominating Committee or the decision of the Board with respect to their resignation. If a director’s resignation is not accepted by the Board, such director will continue to serve until the 2025 annual meeting of shareholders and until their successor is duly elected, or their earlier death, resignation or removal. If a director’s resignation is accepted by the Board, then the Board, in its sole discretion, may fill any resulting vacancy or may decrease the size of the Board.

AMERICAN WATER | 2024 PROXY STATEMENT

DIRECTOR CRITERIA, QUALIFICATIONS, EXPERIENCE AND DIVERSITY

We believe that the backgrounds and qualifications of our directors, considered as a group, should provide a composite mix of experience, knowledge and abilities that will enable the Board to fulfill its responsibilities. Therefore, the Nominating Committee considers diversity in identifying nominees for directors. In this regard, the Nominating Committee views diversity in a broad sense, including, without limitation, on the basis of skills, experience, age, race, gender and ethnicity. The Board believes in balancing the value that longevity of director service can bring with the value of new ideas and insights that can come through new members. In addition, our Corporate Governance Guidelines provide that directors must be persons of good character and thus must possess all of the following personal characteristics:

Integrity: Directors must demonstrate high ethical standards and integrity in their personal and professional dealings.

Accountability: Directors must be willing to be accountable for their decisions as directors.

Judgment: Directors must possess the ability to provide wise and thoughtful counsel on a broad range of issues.

Responsibility: Directors must interact with each other in a manner which encourages responsible, open, challenging and informed discussion.

High Performance Standards: Directors must have a history of achievement which reflects high standards for themselves and others.

Commitment and Enthusiasm: Directors must be committed to, and enthusiastic about, their performance for American Water as directors, both in absolute terms and relative to their peers.

Courage: Directors must possess the courage to express views openly, even in the face of opposition.

The Board strives to have members with knowledge, experience and skills in the following core competencies:

accounting and finance

business judgment

management

crisis response

industry knowledge

utility regulation

leadership, including in other public companies

environmental management

ID&E and human capital management

strategy/vision

technology

In this regard, in evaluating a candidate’s experience and skills, the Nominating Committee will consider qualities such as an understanding of the water industry, utilities, marketing, finance, customer service, utility and environmental regulation, cybersecurity and public policy issues. The Nominating Committee does not assign specific weights to particular criteria and no particular criterion is necessarily applicable to all prospective nominees. In addition, the Board is committed to having directors who add tangible value to American Water with a diversity of ideas, approaches and experiences and the interpersonal capacity to foster effective communication within the Board and with management.

Annually, the Nominating Committee reviews the profile, engagement and performance of each director to determine whether the director should be renominated for Board service. The Nominating Committee also considers whether, in light of our strategy or trends in our market environment, new skill sets or experiences would benefit us and our shareholders.

The process followed by the Nominating Committee to identify and evaluate candidates includes requests to members of the Board and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates, and interviews of selected candidates by members of the Nominating Committee and other members of the Board. The Nominating Committee may engage a third party to assist in the search for director candidates or to assist in gathering information regarding a director candidate’s background and experience. If the Nominating Committee engages a third party, that committee would approve the fee that American Water pays for these services.

When evaluating the recommendations of the Nominating Committee, the Board should take into account all factors it considers appropriate, which may include:

whether the candidate has exhibited behavior that indicates commitment to the highest ethical standards;

DIRECTOR INDEPENDENCE

The NYSE’s listing standards require that:

a majority of our directors and all of the members of the Nominating Committee satisfy the NYSE’s independence standards applicable to all directors;

all of the members of the Audit, Finance and Risk Committee satisfy the NYSE’s independence standards applicable to audit committee members; and

all of the members of the ED&CC satisfy the NYSE’s independence standards applicable to compensation committee members.

Applying these standards, the Board has determined that eight of the nine directors serving on the Board, consisting of Mses. Goss, Harris, Havanec, Johnson and Kampling, and Messrs. Edwards, Kurz and Marberry, qualify as independent. Due to her employment position with the Company, the Board determined that Ms. Hardwick does not qualify as independent.

The Board also has determined that each of Mses. Goss and Kampling, and Messrs. Edwards and Marberry, satisfies the NYSE’s independence standards for audit committee members, and that

each of Mses. Goss, Harris, Havanec, Johnson and Kampling, satisfies the NYSE’s independence standards for compensation committee members.

For a director to be considered independent under the NYSE listing standards, a director cannot have any of the disqualifying relationships enumerated by those standards. Furthermore, the NYSE listing standards state that a director is not independent unless the board of directors affirmatively determines that the director has no material relationship with the listed company (either directly or as a partner, shareholder or officer of an organization that has a relationship with the company). In making this determination, the Board considers all relevant facts and circumstances when assessing the materiality of any relationship of a director with the Company, not only from the standpoint of the director but also from that of persons or organizations with which the director has an affiliation. Material relationships can include, for example, commercial, industrial, banking, consulting, legal, accounting, charitable and familial relationships.

AMERICAN WATER | 2024 PROXY STATEMENT

To assist the Board in considering whether a director has a material relationship with us, the Board has adopted categorical standards of material director relationships. Under these standards, which are based

in part on the disqualifying relationships enumerated by the NYSE’s listing standards, a director will not be deemed independent if any of the following relationships exist:


Type of Relationship (1)				Description of Relationship (1)(2)
Employee or executive officer of American Water				The director is, or has been within the last three years, an employee of American Water, or an immediate family member of the director is, or has been within the last three years, an executive officer of American Water. However, employment as an interim chief executive officer or other officer will not disqualify a director from being considered independent following that employment.
Relationships with internal or external auditor				Any of the following relationships exist: · the director is a current partner or employee of American Water’s internal or external auditor · the director has an immediate family member who is a current partner of the internal or external auditor · the director has an immediate family member who: § is a current employee of the external auditor and § personally works on the Company’s audit · the director or an immediate family member of the director was, within the last three years: § a partner or employee of the internal or external auditor and § personally worked on the Company’s audit within that time
Compensation Committee interlocks				The director or an immediate family member of the director is, or has been within the last three years, employed as an executive officer of another company where any of the Company’s present executive officers at the same time serves or served on that company’s compensation committee.
Receipt of direct compensation from American Water				The director or an immediate family member of the director received, during any 12-month period within the last three years, more than $120,000 in direct compensation from American Water, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service). Compensation received by a director for former service as an interim chief executive officer or other executive officer need not be considered in determining independence under this standard. Compensation received by an immediate family member for service as an employee of American Water (other than as an executive officer) need not be considered in determining independence under this standard.
Receipt of indirect compensation from American Water				The director is a current employee or holder of more than 10 percent of the equity of another company, or an immediate family member of the director is a current executive officer or holder of more than 10 percent of the equity of another company, that has made payments to, or received payments from, American Water or any subsidiary in any of the other company’s last three fiscal years, that exceeds the greater of $1 million or two percent of such other company’s consolidated gross revenues.
Charitable contributions by American Water				The director is a current executive officer of a charitable organization to which American Water or any subsidiary has made charitable contributions in any of the charitable organization’s last three fiscal years that exceed the greater of $1 million or two percent of that charitable organization’s consolidated gross revenues.

(1)	A person’s immediate family includes a person’s spouse, parents, children, siblings, mothers- and fathers-in-law, sons- and daughters-in-law, and brothers- and sisters-in-law and anyone (other than domestic employees) who shares such person’s home.

AMERICAN WATER | 2024 PROXY STATEMENT

(2)

The term “executive officer” is defined to mean the following officers of American Water: President; Chief Financial Officer; Chief Accounting Officer; any Vice President in charge of a principal business unit, division or function; and any other officer who performs similar policy-making functions for American Water. The term also includes any other person who performs similar policy-making functions for American Water. An officer of a subsidiary of American Water would be deemed to be an “executive officer” for purposes of this standard if the officer performs such policy-making functions for American Water.

DIRECTOR EVALUATIONS AND ASSESSMENTS

Each year, directors complete a series of evaluations to assess the performance of the Board and each of the standing committees. The evaluations elicit responses in key areas of Board operation and function and subjective comments from each director. Each committee member evaluates how well the committees on which the member serves are functioning and provides suggestions for improvement.

Since 2017, the Board utilized a peer review process by which each director was asked to provide feedback on a number of characteristics of each of the other directors, including background, leadership, preparation, focus on shareholder interests, participation and independence.

In addition, annually, members of our executive leadership team, comprised of senior executives of the Company who regularly interact with the Board and

the committees, are solicited to provide their input and perspective on the operation of the Board and how the Board might improve its effectiveness.

Finally, our Board Chair also interviews each director individually to obtain their assessment of director performance, Board dynamics and the effectiveness of the Board and its committees, and to discuss the results of the peer review process and their responses to these questions.

A summary of the responses to the questionnaires and the responses received from senior management’s feedback is reviewed by the Board Chair. The summary and related responses with respect to the Board and each committee is ultimately discussed in executive session in meetings of the Board and each respective committee.

DIRECTOR COMPENSATION

As described in the table below, during 2023, our non-employee directors received annual cash retainers, paid in quarterly installments, for their service on the Board. Additionally, each non-employee director received an annual grant of approximately $155,000 in equity compensation ($250,000 for the Board Chair). Our President and Chief Executive Officer did not receive any additional compensation for serving as a director.

Our non-employee director cash compensation as of the date of this proxy statement is as follows:

We do not pay our directors a separate fee for attendance at Board or committee meetings.

For calendar year 2023, Semler Brossy Consulting Group LLC, or Semler Brossy, the ED&CC’s then independent compensation consultant, reviewed American Water’s non-employee director pay program

for market competitiveness. The review determined that the cash and equity compensation paid to our non-employee directors was positioned at the median of our 2023 peer group (as defined below in “Compensation Discussion and Analysis—Compensation Determinations and Pay Competitiveness in 2023” beginning on page 33 of

AMERICAN WATER | 2024 PROXY STATEMENT

LOGO

this proxy statement), and that our Board Chair’s total compensation was also positioned at the median for non-executive chairpersons among the companies in our 2023 peer group with a non-executive chairperson.

As a result of the review, and based on, among other things, data and analyses provided by Semler Brossy, the ED&CC recommended, and the independent members of the Board approved, modest increases in the base elements of our director compensation, which brought each element to approximately the 75th percentile of the compensation peer group, including:

an increase in the director annual base cash compensation from $115,000 to $120,000; and

an increase in the director annual base equity compensation from $150,000 to $155,000.

Each of these compensation decisions were effective as of May 10, 2023. No changes were made to the premiums paid to our non-executive Board Chair or the committee chairs.

Equity compensation for our non-employee directors is paid in the form of stock units under our 2017 Omnibus Plan. The actual number of stock units

granted is based on the closing price of our common stock on the date of grant, which is typically the date the director is elected to the Board. The stock units vest on the date of grant and the shares underlying the stock units are distributed to the directors approximately 15 months after the date of grant, subject to earlier distribution in the event of a change of control or the termination of the director’s service on the Board.

To the extent that a dividend is paid on our common stock prior to the time that shares of common stock may be distributed, the value of the dividend that would have been paid if the stock units had been outstanding shares of common stock is credited to an account for the director. Such dividend equivalents are payable to the director in a lump sum, in cash and without interest, and are paid when shares of common stock underlying the stock units are distributed to the director.

Non-employee directors are reimbursed for expenses incurred in attending Board and committee meetings or other Company-related functions, and expenses incurred for attending up to one director continuing education program each year.

DIRECTOR COMPENSATION TABLE

The following table presents information regarding compensation earned or paid in 2023 as to each person who served as a non-employee member of the Board during that year. George MacKenzie, who did not wish to stand for re-election in 2023, served on the Board until May 10, 2023. Admiral Stavridis served as a member of the Board until his resignation effective February 12, 2024. Admiral Stavridis resigned from the Board to focus on all of his professional and personal obligations. There were no disagreements with the Company on any matter relating to its operations, policies or practices. The

Company and the Board wish to thank Admiral Stavridis for his many years of service as a director.

The table does not include amounts paid for reimbursement of travel expenses related to attending Board and committee meetings or other Company related functions, or any reimbursement of director educational expenses, and does not include compensation earned or paid as to the CEO. See “Executive Compensation” beginning on page 45 of this proxy statement for information relating to the CEO’s compensation.

COMPENSATION DISCUSSION AND ANALYSIS

In this CD&A, we address our compensation philosophy and programs, the key decisions of the ED&CC with respect to these programs and the reasons for those decisions, principally with respect to our NEOs for 2023, who are:

M. Susan Hardwick, our President and Chief Executive Officer;

John C. Griffith, our Executive Vice President and Chief Financial Officer;

Cheryl Norton, our Executive Vice President and Chief Operating Officer;

James H. Gallegos, our Executive Vice President and General Counsel; and

Melanie M. Kennedy, our Executive Vice President and Chief Human Resources Officer.

EXECUTIVE SUMMARY

Compensation Program Overview

Our executive compensation is highly correlated to performance and long-term value creation with a considerable portion of pay earned solely based on performance. Our executive compensation philosophy, which is focused on paying our NEOs for positive performance, is demonstrated by the structure of the principal elements of our executive compensation:

annual base salary;

our APP, which is our annual cash-based performance plan; and

our Long-Term Performance Plan, or LTPP, which is our long-term equity compensation program.

We also offer our executives various employee retirement and health and welfare benefit plans, as well as customary post-termination benefits under our Executive Severance Policy and Change of Control Severance Policy. Finally, we offer limited and customary perquisites, primarily consisting of executive physicals, Company-paid life insurance benefits, and, as applicable, relocation benefits.

Our allocation of compensation among these elements is designed to align our levels of compensation with market pay, which we define as being within a competitive range of the median of our peer group and benchmarking data for a NEO’s position. For 2023, our compensation program for the NEOs consisted of the following key elements:

AMERICAN WATER | 2024 PROXY STATEMENT

LOGO

Summary of Executive Compensation Practices

Below we summarize key components of our compensation programs, which we consider best practices that align the interests of our executive team with those of our shareholders:




We do:				We do not:

· Tie a considerable portion of executive pay to company performance · Weight equity compensation heavily towards performance stock units · Utilize an independent compensation consultant · Require executives to abide by stock ownership guidelines and stock retention requirements · Subject all NEO incentive-based compensation to clawback provisions · Complete an annual compensation program risk assessment, overseen by the ED&CC · Utilize double-trigger vesting of equity awards upon a change in control · Provide reasonable and customary severance arrangements to NEOs				· Provide excise tax gross-ups in our change in control arrangements · Provide employment agreements to our executives, other than customary employment offer letters · Allow hedging, pledging or short selling of our common stock by employees or directors · Allow buying of our common stock on margin by employees or directors · Provide excessive perquisites for executives · Distribute dividend equivalents on equity awards before they vest · Allow executives to sell or transfer stock if not in compliance with stock ownership guidelines, subject to exceptions · Provide for a supplemental executive retirement plan open to new participants

Our Performance in 2023

Some of our performance highlights for 2023 include the following:


Diluted Earnings Per Share, or EPS, Growth				Our 2023 full-year results were $4.90 per share compared to $4.51 per share for 2022, an increase of 8.6 percent compared to 2022. Our 2023 results reflect continued growth in the regulated businesses from infrastructure investment and acquisitions, as well as from organic growth.

Total Debt to Total Capitalization Ratio				As of December 31, 2023, the Company’s ratio of consolidated debt to consolidated capitalization was 0.56 to 1.00, an improvement from December 31, 2022, when the ratio was 0.62 to 1.00.

Regulated Businesses Customer Growth				Approximately 18,100 new customers added in 2023 through regulated acquisitions and approximately 18,800 new regulated customers added in 2023 through organic growth.

Annual Dividend Growth				9.3 percent overall five-year compounded annual growth rate of annual dividends anchored off 2018 dividends paid, and 15 years in a row of annual dividend increases

AMERICAN WATER | 2024 PROXY STATEMENT

ED&CC did not believe that any corresponding action or change in our compensation program was needed for 2023.

At our 2024 annual meeting, we will again hold our say-on-pay advisory vote. In making executive compensation decisions, the ED&CC will continue to

consider the results of this advisory vote, as well as feedback obtained from shareholders throughout the course of the year. Information regarding our shareholder outreach during 2023 can be found in “Board of Directors and Corporate Governance—Shareholder Outreach” on page 13 of this proxy statement.

COMPENSATION DETERMINATIONS AND PAY COMPETITIVENESS IN 2023

For 2023, the ED&CC reviewed and approved all compensation paid to our NEOs, and made recommendations to the independent members of the Board with respect to compensation paid to the CEO, which the independent members of the Board approved. The CEO did not participate in the ED&CC’s recommendations regarding the CEO’s compensation and was excused from those portions of the ED&CC and Board meetings during which the CEO’s compensation was deliberated upon and approved.

The ED&CC considered the CEO’s assessments of the performance of the other NEOs, as well as the CEO’s compensation recommendations regarding each such NEO’s base salary and their APP and LTPP target award opportunities. The ED&CC, with the CEO’s participation, discussed the performance of each NEO other than the CEO, and, after discussion and deliberation held in executive session, approved compensation determinations for such NEOs.

The ED&CC engaged Semler Brossy as its independent compensation consultant through May 31, 2023. Beginning June 1, 2023, the ED&CC engaged Aon Human Capital Solutions, or Aon, as the independent compensation consultant after the completion of a request for proposal process. The Aon team was selected primarily because of its experience within the utility industry. The ED&CC assessed the independence of Semler Brossy and Aon and concluded that both were independent as determined under SEC and NYSE rules.

Through its review of relevant benchmarking data and executive compensation trends presented by its independent compensation consultants, the ED&CC is able to assess competitive market compensation practices. Two of the primary ways the ED&CC evaluates and benchmarks our executive compensation arrangements and practices is to review them against market data in a Willis Towers Watson study comprised of 60 percent weighting on publicly traded utilities and 40 percent weighting on general industry companies, as well as to similar data on companies in our compensation peer group, as described below. The

market survey of utility and energy industry companies includes only public utilities, which more closely resemble our business and operations. The ED&CC believes there is a strong likelihood that an executive officer’s skills will be transferable among these companies, and thus we would expect to compete with these companies and others for executive officer talent. The ED&CC referred to all of this benchmarking data as part of its review of general compensation practices and trends of the utility industry and our compensation peer group.

In October 2022, the composition of our compensation peer group was reviewed by the independent compensation consultant and was reassessed by the ED&CC as part of its annual review to consider structural and methodology changes, as well as corporate transactions or other events that may affect the comparability of one or more of the constituent companies. In reviewing the appropriateness of our peer group companies, the ED&CC considers factors that most reflect our primary business of owning water and wastewater utilities subject to economic regulation by state utility commissions or similar entities, including, in decreasing order of relevance, consolidated total assets, market capitalization and consolidated revenues of companies that primarily operate (greater than 75 percent of revenue) as a regulated utility. After consideration of these factors, only companies that primarily operate as a regulated utility were selected as peer companies. In connection with this review, the ED&CC approved the removal of UGI Corporation from, and the addition of Public Service Enterprise Group, Inc. to, our 2023 compensation peer group. Throughout 2023, compensation benchmarking decisions and grants of PSU awards based upon relative TSR were made using the 2023 peer group of the companies listed in the table below.

In December 2023, based on a review of our peer group’s pay practices and in consultation with Aon, the ED&CC approved changes to the 2024 APP. To align with our peer group, the ED&CC approved removing the provision that no payouts would be earned under the APP if the EPS performance measure was less than

AMERICAN WATER | 2024 PROXY STATEMENT

LOGO

90 percent of target and also approved increasing the maximum payout to 200 percent for the non-financial APP measures. The ED&CC also approved including a return on equity, or ROE, performance measure to the 2024 LTPP. This additional LTPP financial measure aligns with our business strategy and is a key performance indicator in the utility industry. The 2024

LTPP awards are weighted 30 percent to time-based RSUs and 70 percent to PSUs, with the PSU component consisting of three performance measures including compounded EPS growth weighted at 35 percent, relative TSR weighted at 20 percent, and ROE weighted at 15 percent of the total LTPP award.

2023 COMPENSATION

Compensation Philosophy and Objectives

Our executive compensation program is designed to reward our NEOs for delivering results and building long-term sustainable value for our shareholders and customers. Our program’s structure aligns the interests of our shareholders, customers, and NEOs by correlating pay to our short- and long-term performance.

We focused on the following objectives in making compensation decisions with respect to our NEOs in 2023:

incentivize our NEOs to achieve superior financial and non-financial performance relating to safety, customers, people, environmental leadership, operational excellence and growth, all of which lead to long-term financial strength and value creation without incentivizing excessive risk-taking;

focus pay on an appropriate mix of short- and long-term performance, with a proportionately greater emphasis on long-term compensation;

build long-term, sustainable value for shareholders by emphasizing long-term performance- and equity-based compensation, and de-emphasizing short-term, cash-based compensation;

align our core strategies of safety, customers, people, operational excellence and growth with our short-term APP performance measures;

provide compensation to our NEOs that reflects their responsibilities and contributions, and that is aligned to market pay — meaning within a competitive range of the median of compensation reflected in our benchmarking data — to attract, motivate and retain high-caliber executives; and

align NEO and shareholder interests by requiring consistent, meaningful equity ownership.

Base Salaries

For 2023, the ED&CC approved base salary increases as reflected in the table below. The ED&CC reviews base salary in the context of responsibilities, experience, relevant benchmarking data, and

individual performance of each NEO. The following table sets forth the base salaries of each NEO as of the end of the 2022 and 2023 calendar years, as well as the percentage change from the prior year.

AMERICAN WATER | 2024 PROXY STATEMENT

2023 Annual Performance Plan

The APP is designed to provide a portion of a NEO’s at-risk compensation to be paid upon the achievement of our annual business objectives. The APP provides an opportunity for NEOs to earn cash payouts tied to the satisfaction of annual corporate performance goals.

The 2023 target award opportunity for each NEO was equal to a percentage of each NEO’s base salary, based on the individual’s position with American Water. An APP award target is set by the ED&CC,

together with the NEO’s other elements of compensation, in an effort to align the NEO’s annual total direct compensation generally with market pay for their position. For 2023, Ms. Hardwick’s APP target was increased from 110 percent to 120 percent of her base salary to maintain her total direct compensation within the competitive range of the benchmarking data. Information used to calculate the 2023 APP award payouts for each NEO is included in the table below.


Named Executive Officer	Percentage of Base Salary			2023 APP Target (1)		2023 APP Payout Percentage			2023 APP Award
M. Susan Hardwick		120	%	$	1,269,271		132.25	%	$	1,678,611

The APP performance measures selected for 2023 align with our core business strategies of growth, customers, safety, operational excellence (in this case, environmental leadership) and people. The following table provides details on each performance measure.



Strategy	Performance Measure	How We Calculate the Measure	Why We Use this Measure

Growth	Adjusted Earnings Per Share (Adjusted EPS)	Adjusted EPS is a non-GAAP measure which is calculated as diluted EPS calculated in accordance with GAAP as reported in the Company’s audited consolidated financial statements, adjusted to eliminate the impact of the items shown in Part A of Appendix A.	Adjusted EPS is a key measure of our financial and operational success, and achieving our earnings and strategic goals creates long-term shareholder value, provides greater total return to our shareholders, and benefits customers by contributing to strong credit metrics to provide for cost-effective financing of necessary capital and operational investments.

Customers	Customer Satisfaction	A quarterly survey is conducted by a third-party firm of random regulated water and wastewater customers, and the results are aggregated and weighted for each individual state.	We are committed to delivering the best customer experience, setting our goal to achieve top-quartile customer satisfaction. Our service quality and ability to satisfy our customers are closely tied to the trust our customers extend to us each day.

Safety	OSHA Recordable Injury Rate (ORIR)	ORIR is a measure of injuries and illnesses requiring treatment beyond first aid for every 200,000 hours worked.	ORIR allows us to continue our momentum toward becoming an industry leader with respect to the safety and well-being of our workforce.

	Days Away, Restricted and Transfer (DART) severity rate	DART injury rate measures the number of OSHA defined recordable injuries that resulted in days away from work, work restrictions, or job duty/position transfers in the calendar year per 100 employees.	DART reflects serious incidents that result in the employee being placed in restricted duty or time away from work. This aligns with both our safety and people strategies as we believe that our employees should return home in the same or better condition than when they arrived to work.

As part of our sustainability initiatives, we are committed to protecting the environment and maintaining our history of materially complying with, and in many cases, surpassing, minimum standards required by applicable laws and regulations.

	Drinking Water Quality NOV	This metric is determined by counting the overall number of drinking water NOVs for maximum contaminant level exceedances received by the Company in accordance with internally established procedures, which may exclude NOVs related to newly acquired systems and associated with third-party violations, among others.	We are committed to excellent water quality and maintaining our history of materially complying with, and in many cases, surpassing, minimum standards required by applicable laws and regulations.

People	Women Representation	This people metric is determined by dividing the number of employees who self-identify as female by the total employee headcount.	We are committed to closing the gender gap and maintaining a culture of inclusion. We recognize the benefits of increasing the percentage of women in our workforce to better reflect the customers and communities in which we serve.

	Ethnic and Racial Diversity Representation	This people metric is determined by dividing the number of employees who self-identify as a member of a diverse racial or ethnic group by the total employee headcount.	We are committed to hiring diverse talent and believe that diversity creates stronger teams, better ideas, innovative ways of working, long-term sustainability and, ultimately, an organization that reflects the customers and communities in which we serve.

For 2023, the maximum payout for each of the performance measures was set at 150 percent of target, except for the Adjusted EPS performance measure, which was set at 200 percent of target to reflect the rigor of this goal and to recognize the difficulty in achieving earnings growth significantly above our plan. No payouts would have been earned under the 2023 APP if EPS was less than 90 percent of target.

The ED&CC determines the APP payout percentage, using the actual performance of each measure, as soon as reasonably practicable after the end of the year. The APP payout percentage is then computed by adding the weighted results achieved for each performance measure.

The ED&CC has adopted guidelines to permit management to make adjustments to EPS for purposes of computing APP performance goals based on Adjusted EPS, to the extent greater than $0.02 per share. Please see Part A of Appendix A for details on Adjusted EPS. The ED&CC retains authority to approve other adjustments not covered by this authorization.

The following table presents information regarding each of the performance measures used to determine the APP payout percentage, including the threshold, target and maximum performance levels for each measure, as well as the weighting assigned to each measure. If the threshold performance level for a performance measure is not met, there is no payout for that measure.

(1)	Adjusted EPS is a non-GAAP measure. See Part A of Appendix A for a reconciliation.

(2)	This goal would not have been earned in the event of a preventable employee fatality during the year.

Based upon our performance with regard to the financial and non-financial performance measures, the ED&CC certified an APP payout of 132.25 percent.

Cash awards under the APP are generally paid to participants by March 15 of the year following the performance year.

2023 Long-Term Performance Plan

The LTPP is designed to incentivize eligible participants to achieve our long-term business objectives by providing an opportunity to earn equity awards tied to our long-term goals and continued employment with the Company. LTPP awards are generally granted by the ED&CC in February of each year and allocated 30 percent to time-based RSUs and 70 percent to PSUs. PSU awards for 2023 were allocated equally between shares that may be earned based on TSR relative to the companies in the 2023 peer group and shares that may be earned based on the rate of our compounded EPS growth. Stock options were not granted as part of the LTPP.

Generally, our RSU awards vest ratably over an approximate three-year period while a participant remains employed with us. PSU awards generally are earned ratably over a three-year performance period while employed, and the vesting of each PSU award is

determined by the ED&CC following the end of the three-year performance period based on the satisfaction of pre-determined performance goals. To the extent an RSU award is unvested or a PSU award has not been earned, it is generally forfeited once a participant ceases to be employed with us or if the performance goals are not achieved; however, LTPP awards to certain NEOs may continue to vest after an early or normal retirement. See “—Ongoing and Post-Employment Arrangements and Benefit Plans—Terms of Outstanding Equity Grants” beginning on page 43 of this proxy statement for additional details.

The ED&CC has adopted guidelines to permit management to make adjustments for purposes of LTPP performance goals based on EPS, to the extent greater than $0.02 per share. The ED&CC retains authority to approve other adjustments not covered by this authorization.

We based the aggregate target value of LTPP awards on a percentage of each NEO’s salary. The following table presents a summary of the grant date fair value of LTPP target awards granted in 2023 for each NEO. Information regarding the number of shares underlying these awards is found in “Executive Compensation—2023 Grants of Plan-Based Awards” on page 48 of this proxy statement. To keep total targeted

compensation in line with the competitive range of the benchmarking data, Ms. Hardwick’s LTPP award target for 2023, as a percentage of her base salary, was increased from 400 percent to 435 percent, and Ms. Norton’s LTPP award target for 2023, as a percentage of her annual base salary, was increased from 175 percent to 200 percent.

The following table presents information regarding the performance measures related to the PSUs granted in 2023. Relative TSR is based on American Water’s total shareholder return compared to the total shareholder return performance of the companies in the 2023 peer group, during the three-year performance period from January 1, 2023, through December 31, 2025, assuming reinvestment of dividends during the performance period. The TSR

metric enables us to encourage performance that increases shareholder value and also increases it to an extent that compares favorably relative to the companies in our 2023 peer group. Compounded EPS growth is based on the rate of EPS growth, compounded annually over the three-year period from January 1, 2023, through December 31, 2025, over our 2022 EPS.

LOGO

For 2023 LTPP awards, the threshold, target and maximum performance goals related to the compounded EPS growth rate metric for the three-year period from January 1, 2023, through December 31, 2025, compared to our 2022 adjusted EPS, were based on the relevant period of our long-term, five-year financial plan that was reviewed and approved by the Board in the fall of 2022. These goals were set by the

ED&CC in December 2022, after review by its independent compensation consultant. These goals reflected the period of that financial plan whereby proceeds from the sales of HOS in December 2021 and New York American Water in January 2022 were to be redeployed over time into the regulated businesses as we transitioned to a substantially regulated business.

AMERICAN WATER | 2024 PROXY STATEMENT

Performance Vesting of PSUs Granted in 2021

In 2021, we granted two equally weighted types of PSUs to our NEOs: one with a three-year performance measure based on total shareholder return relative to companies in our 2021 peer group, and the other with a three-year performance measure based on the annual rate of our compounded adjusted EPS growth. The payouts of the two types of PSUs are summarized in the table below:


Performance Measure	Threshold Performance (Weighting)	Target Performance (Weighting)	Maximum Performance (Weighting)	Actual Performance	Percentage of Target Award Earned
Relative Total Shareholder Return	25th percentile (25%)	50th percentile (100%)	90th percentile (200%)	12th percentile	0.00%
Compounded Adjusted EPS Growth Rate	6.0% (0%)	8.0% (100%)	10.0% (200%)	9.91% (1)	197.75%

(1)	See Part B of Appendix A for a calculation of actual performance for this 2021 PSU award.

Actual performance is based on the rate of EPS growth, compounded annually over the three-year period from January 1, 2021 through December 31, 2023, over our 2020 adjusted EPS. To reflect the sale of HOS in December 2021, in January 2022, the ED&CC approved the amendment and adjustment of the outstanding 2021 PSU awards based on our

compounded EPS growth. See “Executive Compensation—2023 Summary Compensation Table—Modification of 2021 PSU Awards During 2022” beginning on page 47 for a discussion of these amendments and adjustments. The ED&CC certified the achievement of the requisite PSU performance measures in February 2024.

Limited Perquisites and Other Benefits

We provide limited perquisites to our NEOs, consisting principally of reimbursement for executive physicals, Company-paid life insurance benefits, and, where applicable, relocation assistance. We believe that providing executives with limited perquisites supports our emphasis on performance-based pay, while

providing NEOs with a benefit package that is competitive and supports executive retention. The incremental costs of certain of these perquisites are described in footnote (5) to the Summary Compensation table on page 46 of this proxy statement.

EXECUTIVE STOCK OWNERSHIP GUIDELINES AND STOCK RETENTION REQUIREMENTS

The Board has adopted executive stock ownership guidelines and complementary stock retention requirements that further emphasize the importance of linking the financial interests of our executives with those of our shareholders. The stock ownership guidelines are expressed as a multiple of annual base

salary. Executives (directly or through immediate family members or controlled entities) are expected to hold a specified amount of common stock (including certain equivalents) based on the executive’s position, as follows:


Officer Level				Multiple of Annual Base Salary
Chief Executive Officer				6 times
Chief Operating Officer				3 times
Executive Vice Presidents				3 times
Senior Vice Presidents				3 times
Vice Presidents and Line of Business Presidents				1 time

For purposes of the executive stock ownership guidelines, shares of common stock, shares underlying vested and unvested RSUs and shares underlying vested PSUs count toward satisfying the

ownership guidelines. Shares underlying vested or unvested stock options and unvested PSUs do not count.

Under our executive stock ownership guidelines, to sell or transfer shares of common stock, and subject

AMERICAN WATER | 2024 PROXY STATEMENT

LOGO

to certain exceptions, each executive must be in compliance with the stock ownership guidelines at the time of the sale or transfer. Sales or transfers will be permitted to the extent they do not cause the executive’s total ownership to fall below the required threshold.

Each executive who becomes subject to the stock ownership guidelines has five years to comply with them. The stock ownership guidelines provide that in the event of a promotion that increases an executive’s

multiple of base salary, a new five-year compliance period will begin to run for that executive as of the effective date of the promotion.

Mses. Kennedy and Norton are in compliance as of the record date and all of our other NEOs covered by the stock ownership guidelines are within their five-year compliance period. The compliance period for each of Ms. Hardwick and Messrs. Griffith and Gallegos ends in 2027.

POLICIES PROHIBITING HEDGING, PLEDGING, MARGINING AND SHORT SELLING, AND WITH RESPECT TO RULE 10B5-1 TRADING PLANS

Our insider trading policy prohibits all directors, officers (including our NEOs) and employees (among others), including their immediate family members and controlled entities, from engaging in any hedging transaction. No covered person may:

enter into any hedging transaction, as described in the insider trading policy;

buy or sell any security that derives its value from the price of any of our securities; or

enter into any other transaction of a similar nature that has the effect of reducing or eliminating the investment risk associated with any of our securities owned by such covered person.

The above restrictions are intended to prohibit transactions in financial instruments involving our securities, including prepaid variable forward contracts, equity swaps, collars and exchange funds, as well as transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of our equity and debt securities.

Our insider trading policy also prohibits covered persons from pledging our securities to a lender as collateral for a loan, from using them in a margin account as collateral for any obligation incurred in connection with a purchase of securities, or for entering into any other similar transaction that has the effect of using our securities as collateral or security for a loan or any other obligation. In addition, the policy prohibits covered persons from selling our securities short, which is the practice of selling securities that are not owned by the seller. This prohibition includes “short sales against the box,” where the seller actually owns the securities being sold but fails to deliver them to the purchaser within a specified time period after the sale. The insider trading policy requires directors and NEOs to obtain review and approval from senior executive management and the Company’s SEC Counsel prior to implementing or terminating any Rule 10b5-1 trading plan.

A copy of our insider trading policy is included on our Investor Relations website at ir.amwater.com.

ONGOING AND POST-EMPLOYMENT ARRANGEMENTS AND BENEFIT PLANS

We have several agreements, plans and arrangements that enable our NEOs to accrue retirement benefits as they continue to work for us, provide severance benefits upon certain types of termination of employment, or provide other forms of deferred compensation. Not all of these plans apply to each

NEO, as indicated in the discussion below. None of our executives participating in any of these plans is entitled to receive excise tax gross-up payments thereunder. The Company believes these programs are important recruitment and retention tools.

AMERICAN WATER | 2024 PROXY STATEMENT

American Water Savings Plan

The Savings Plan for Employees of American Water Works Company, Inc. and its Designated Subsidiaries, or the Savings Plan, is a tax-qualified 401(k) defined contribution plan available to employees of American Water, including our NEOs, and certain subsidiaries.

Under the Savings Plan, employees may contribute, subject to limitations imposed by the Internal Revenue Code of 1986, as amended, or the Code, up to 50 percent of their base salary and up to 100 percent of their APP award, up to limits determined under the Code.

For a NEO participant hired before January 1, 2006 (for 2023, this applies to Ms. Norton), the matching contribution formula is 50 percent of a participant’s base salary contributions to the Savings Plan for the plan year, up to a maximum of 5 percent. For NEO participants hired or rehired on or after January 1, 2006 (for 2023, this applies for all NEOs except Ms. Norton), the matching contribution formula is (a) 100 percent of a participant’s base salary and APP

contributions to the Savings Plan for the plan year up to the first 3 percent, and (b) 50 percent of a participant’s base salary and APP contributions to the Savings Plan for the plan year up to the next 2 percent. The Savings Plan does not match a participant’s catch-up contributions. In addition, for NEO participants hired or rehired after January 1, 2006 (for 2023, this applies for all NEOs except Ms. Norton), we provide an employer defined contribution equal to 5.25 percent of the participant’s base salary, subject to limitations imposed under the Code. We provide more generous contributions to participants rehired or hired on or after January 1, 2006, because they are ineligible to participate in the defined benefit pension plans described below.

Amounts credited to an employee’s account may be invested among a number of investment funds, and the value of a participant’s account will increase or decrease to reflect the performance of selected investments.

Pension Plan and Executive Retirement Plan

The Pension Plan for Employees of American Water Works Company, Inc. and its Designated Subsidiaries, or the AWWPP, is a tax-qualified defined benefit pension plan that is generally available to eligible employees who commenced employment with us prior to January 1, 2006. The AWWPP provides an annual retirement benefit based on an employee’s earnings and years of service. For executives hired prior to July 1, 2001, a grandfathered benefit is provided. Ms. Norton is the only NEO who participates in the AWWPP.

The American Water Works Company, Inc. Executive Retirement Plan, or the ERP, is a nonqualified defined benefit pension plan that provides pension benefits under the same formula as the AWWPP, but without the pay and benefit limitations that are applicable to the AWWPP under the Code. The ERP also provides a

minimum benefit in accordance with the provisions of former executive retirement plans. Ms. Norton is the only NEO who participates in the ERP.

We closed the AWWPP (subject to certain exceptions) and the ERP to new employees on December 31, 2005, and replaced those plans with defined contribution plans. This action was taken for a number of reasons, including to allow us to incur fixed costs for retirement benefits on an ongoing basis. In contrast, we are subject to variable costs in connection with our defined benefit plans based on the performance of the plans’ investment portfolios. For further information on these plans, see “Executive Compensation—Pension Benefits at December 31, 2023” and “Executive Compensation—Description of Pension and Other Retirement Plans” beginning on page 51 of this proxy statement.

Nonqualified Deferred Compensation Plan

The Nonqualified Savings and Deferred Compensation Plan for Employees of American Water Works Company, Inc. and its Designated Subsidiaries, or the Employee Deferred Compensation Plan, enables participants to defer up to 20 percent of their base

salary and up to 100 percent of their APP award and provides benefits in excess of the maximum benefits that may be provided under the Savings Plan as a result of limits imposed by the Code. We refer to compensation in excess of those limits as “excess

AMERICAN WATER | 2024 PROXY STATEMENT

LOGO

compensation.” Each of our NEOs is eligible to participate in the Employee Deferred Compensation Plan.

We provide matching contributions on excess compensation using the same matching formulas as described above under the Savings Plan. In addition, for participants rehired or hired on or after January 1, 2006 (for 2023, all NEOs except Ms. Norton), we provide an employer defined contribution that is equal to 5.25 percent of the participant’s APP award plus the participant’s base salary in excess of the compensation limit imposed by the Code.

Each participant may allocate amounts credited to their account among several notional investments, and the value of the account will be increased or decreased to reflect returns under the selected notional investments. The participant may elect to receive payment of deferred amounts in a lump sum or in annual installments, on or beginning at separation from service or a specified distribution date. See “Executive Compensation—2023 Nonqualified Deferred Compensation” beginning on page 52 of this proxy statement for additional information.

Executive Severance Policy

Under our Executive Severance Policy, we provide severance benefits to our NEOs. Our policy is designed to provide a clear statement of the rights of our executives if they are involuntarily terminated without cause (as defined under the policy), except in cases following a change of control, as discussed below. Among other things, the Executive Severance Policy provides for 18 months and 12 months of salary continuation for our CEO and other NEOs, respectively, and a pro rata APP award for the year in which the termination date occurs to the extent a

payment is earned under the terms of the APP. In addition, the policy provides for Company-paid welfare benefits for a specified number of weeks based on years of service, up to 12 months of outplacement services, and credit for the severance period for purposes of vesting under any applicable nonqualified deferred compensation or defined benefit retirement plans. See “Executive Compensation—Potential Payments on Termination or Change of Control” beginning on page 53 of this proxy statement for further information.

Change of Control Severance Policy

The Change of Control Severance Policy provides benefits to each of our NEOs, if within 24 months after the consummation of a “change of control,” the NEO’s employment is involuntarily terminated without “cause” or if the NEO resigns from employment for “good reason” (each as defined in this policy). The occurrence or potential occurrence of a change of control transaction often creates uncertainty regarding the continued employment of a company’s executive officers. In order to continue to encourage our NEOs to remain employed with us in connection with such a transaction, or to attract new executives in the midst of such a transaction, we provide our NEOs with specified severance benefits if the NEO’s employment terminates for the reasons described above in connection with a change of control.

In the event of a covered termination, the CEO and the other NEOs would be eligible to receive three times and two times, respectively, the sum of (1) such NEO’s annual base salary on the termination date of employment and (2) the greater of the last annual award paid to the NEO under the APP, or the average of the last three such annual APP awards. Each NEO would also receive paid COBRA coverage for health,

dental and vision benefits for the maximum statutory period, would continue to be eligible to participate for six months in our Employee Assistance Plan and would receive up to 12 months of outplacement services. The Change of Control Severance Policy also provides that, in the event of a covered termination, each NEO would be entitled to receive unpaid base salary due for periods prior to the termination date, all accrued and unused vacation through the termination date, and reimbursement of all properly documented reasonable and necessary expenses incurred in connection with employment prior to the termination date. In addition, the policy provides that benefits payable to a NEO under the Employee Deferred Compensation Plan shall be fully vested, and the timing of payment of such benefits shall remain subject to the terms of such plan.

The benefits and payments provided under this policy are designed to replace and enhance existing benefits payable under the Executive Severance Policy following a change of control.

See “Executive Compensation—Potential Payments on Termination or Change of Control” beginning on page 53 of this proxy statement for further information.

AMERICAN WATER | 2024 PROXY STATEMENT

Terms of Outstanding Equity Grants

Acknowledging that executives serving in our CEO, CFO and COO positions consistently make decisions that are both in our short- and long-term interests, the ED&CC has approved the granting of long-term equity awards under the 2017 Omnibus Plan to persons serving in these roles to provide for continued vesting after retirement under certain circumstances as discussed in more detail below.

Except as contemplated in these limited circumstances, we do not provide for continued vesting of long-term equity awards granted under the 2017 Omnibus Plan in the event of retirement. For an executive serving in the CEO, CFO or COO role with at least three years of consecutive service in one or more of these positions, an equity award will continue to vest over the normal vesting schedule following a

separation of service based upon either normal retirement or early retirement, as follows:

in the event of a normal retirement, defined as having attained age 60 and five years of service at American Water, 100 percent of the award will continue to vest; and

in the event of an early retirement, defined as having attained age 55 and five years of service at American Water, 75 percent of the award will continue to vest.

In connection with the foregoing, PSUs will continue to vest and shall be paid at the end of the three-year performance period based on actual performance.

Any stock option granted to an executive serving in the CEO, CFO and COO roles will remain exercisable for a period of two years after the retirement date; however, no stock options have been granted to any of our executives in these roles.

CHANGE OF CONTROL PROVISIONS IN EQUITY PLANS

Most of our compensation plans and policies do not contain change of control provisions affecting the compensation of our NEOs. Upon a change of control in which American Water is not the surviving entity, the 2017 Omnibus Plan requires all unexercised options and other grants of awards thereunder to be assumed by or converted to similar awards of the acquiring company. The vesting of such assumed or converted awards will be accelerated only if the participant’s employment is terminated other than (i) for cause or

(ii) due to death or disability, within 12 months after the change of control. To the extent any such awards are not assumed or converted, option awards will become fully exercisable, all restrictions upon awards will lapse and all stock units will fully vest, upon the change of control. See “Executive Compensation—Potential Payments on Termination or Change of Control—Equity Awards” beginning on page 55 of this proxy statement for further information.

RECOVERY OF INCENTIVE COMPENSATION

In September 2023, the ED&CC reviewed and recommended to the Board, and the Board approved and adopted, effective December 1, 2023, an Incentive-Based Compensation Recovery Policy applicable to all Section 16 officers. The new policy complies with, and will be interpreted and administered in a manner consistent with, all applicable laws, the rules and regulations of the NYSE and Rule 10D-1 of the Exchange Act.

Under the policy, in the event the Company is required to prepare a restatement, the Company will, as promptly as reasonably possible, recover any incentive-based compensation erroneously received by a covered executive during the recovery period. The amount of compensation erroneously received by a covered executive will be equal to the excess of the incentive-

based compensation received by such executive based on the erroneous data in the financial statements over such compensation based on the restated results, without respect to any tax liabilities incurred or paid by such executive. We may also seek to recover incentive-based payments if a covered executive commits acts of fraud, embezzlement, theft or other ethical misconduct (as determined by the Board in its sole discretion), and a restatement by the Company is not required. In addition to recovery, the Board may take any and all other actions it deems necessary, appropriate and in the Company’s best interest, including termination of the covered executive’s employment and initiating legal action against the covered executive. Moreover, the terms of the APP and the 2017 Omnibus Plan specifically require that grants under those plans be subject to this policy.

Employment Offer Letters

Historically, when a new NEO joins us, we enter into an employment offer letter with the NEO (which is filed with the SEC) providing for the initial terms of the NEO’s compensation. The 2023 Summary Compensation Table above reflects compensation that is ultimately earned and paid to our NEOs pursuant to these offer letters.

Under the terms of Ms. Hardwick’s and Mr. Griffith’s 2022 employment offer letter, each of them received

annual base salary, an APP award opportunity and an LTPP award opportunity, the latter of which is to vest ratably over three years and has the continued vesting provisions applicable to an executive serving in the CEO or CFO role. In addition, Mr. Gallegos’s 2022 employment offer letter provided him with stated annual base salary, APP and LTPP award opportunities, and, as a sign-on benefit, a grant of $1 million in RSUs that vests ratably over three years.

Modification of 2021 PSU Awards During 2022

In January 2022, to reflect the sale of HOS in December 2021, the ED&CC approved the amendment and adjustment of the outstanding 2021 PSU awards based on our compounded EPS growth. First, the starting EPS was decreased by $0.40, which is equivalent to the contribution of the HOS business to the Company’s EPS in the 2020 fiscal years. Second, the ending EPS for these awards was

adjusted to exclude the impact of income recognized under a secured seller note and revenue share agreements entered into in connection with the HOS sale. These adjustments are reflected in the calculation of the three-year compounded EPS growth rate used to determine achievement of the EPS performance goal for the 2021 PSU awards.

In 2023, for discounting annuity payments, we used a discount rate of 5.18 percent and mortality table of Pri-2012 projected forward using generational Scale MP-2021, and for calculating lump sums, we used an interest rate of 5.18 percent and the IRS Prescribed Table for Lump Sums for 2024.

In 2022, for discounting annuity payments, we used a discount rate of 5.58 percent and mortality table of Pri-2012 projected forward using generational Scale MP-2021, and for calculating lump sums, we used an interest rate of 5.58 percent and the IRS Prescribed Table for 2023.

AMERICAN WATER | 2024 PROXY STATEMENT

For further information on American Water’s defined benefit pension plans, see “—Description of Pension and Other Retirement Plans” below and “—Potential Payments on Termination or Change of Control—AWWPP and ERP.”

DESCRIPTION OF PENSION AND OTHER RETIREMENT PLANS

AWWPP

The AWWPP is a qualified pension plan that is generally available to eligible employees who commenced employment with us prior to January 1, 2006. The AWWPP generally provides participants hired prior to July 1, 2001, including Ms. Norton, a grandfathered benefit. For years of service prior to July 1, 2001, the grandfathered benefit is calculated to be:

1.85 percent of the final average pay up to the Social Security average wage base multiplied by years of service (up to a maximum of 25 years of service through July 1, 2001), plus

2.1 percent of final average pay in excess of the Social Security average wage base multiplied by years of service (up to a maximum of 25 years of service through July 1, 2001), plus

0.7 percent of final average pay multiplied by years of service in excess of 25 years of service through July 1, 2001.

For years of service after July 1, 2001, for participants hired prior to July 1, 2001, the grandfathered benefit is calculated to be:

1.6 percent of final average pay up to the Social Security average wage base multiplied by years of service after July 1, 2001 (up to a maximum of 25 years of service prior to July 1, 2001), plus

2.1 percent of final average pay in excess of the Social Security average wage base multiplied by

years of service after July 1, 2001, (up to a maximum of 25 years of service prior to July 1, 2001), plus

1.6 percent of final average pay multiplied by years of service after July 1, 2001, in excess of 25 years of service prior to July 1, 2001.

Final average pay is defined for purposes of the plan as the average sum of base pay plus APP payout for the highest 60 consecutive months out of the final 120 months of employment. Normal retirement is defined as age 65, and early retirement eligibility is satisfied when an employee’s age is at least 55 and the employee has attained a service requirement that varies based on whether the employee is in a grandfathered group and, if so, the location of such group. Benefits vest in the AWWPP upon completion of five years of service.

Ms. Norton is vested in her pension benefits. The normal form of payment is a single life annuity for single participants and a 50 percent joint and survivor annuity for married participants. The 50 percent joint and survivor annuity benefit amount is determined to be actuarially equivalent to the single life annuity amount.

The plan provisions include a reduction in benefits for early retirement for participants other than those who retire at age 62 or older with specified service levels, such as 20 years of service for someone who is age 62.

ERP

The ERP is a nonqualified defined benefit pension plan that is available to eligible employees who commenced employment with us prior to January 1, 2006. The ERP provides benefits under a restoration formula that mirrors the benefit formulas under the AWWPP, but without the pay and benefit payment limitations that are applicable to the AWWPP under the Code and including deferred compensation in calculating final average pay. The ERP also provides a minimum benefit in accordance with provisions of former executive retirement plans. Ms. Norton participates in this

nonqualified pension plan and is entitled to the greater of the benefits determined pursuant to the restoration formula under the ERP and the benefits determined pursuant to her prior nonqualified plan formulas (if applicable). Ms. Norton is vested in this nonqualified pension benefit. Upon retirement, nonqualified plan benefits are payable as a lump sum unless the participant has elected an alternate form of payment pursuant to regulations under Section 409A of the Code. Ms. Norton will receive her benefits as a lump

LOGO

sum. Upon voluntary termination of employment prior to eligibility for early or normal retirement, nonqualified benefits are payable as deferred (to age 65) annuities or lump sum equivalents of such deferred annuities. All

nonqualified plan lump sums are calculated as the present value of deferred or immediate single life annuities.

DESCRIPTION OF THE EMPLOYEE DEFERRED COMPENSATION PLAN

For our NEOs, the Employee Deferred Compensation Plan permits the deferral of up to 20 percent of a participant’s base salary and up to 100 percent of a participant’s bonus each year on a tax-advantaged basis. It also provides for annual matching contributions determined by the following formula for our NEOs hired or rehired on or after January 1, 2006, namely Mses. Hardwick and Kennedy and Messrs. Griffith and Gallegos:

the sum of:

100 percent of a participant’s voluntary deferrals for the year, up to a maximum of

three percent of the sum of the participant’s base salary and bonus; and

50 percent of a participant’s voluntary deferrals for the year, up to a maximum of the next two percent of the sum of the participant’s base salary and bonus, less

the maximum amount of matching contributions that the participant is eligible to receive under the Savings Plan for the year.

LOGO

AMERICAN WATER | 2024 PROXY STATEMENT

In addition, we make annual contributions for our NEOs hired or rehired on or after January 1, 2006, equal to the sum of:

5.25 percent of the NEO’s base salary in excess of the dollar limitation in effect under Section 401(a)(17) of the Code with respect to the year; and

5.25 percent of the NEO’s bonus.

For our NEOs hired before January 1, 2006, namely, Ms. Norton, the matching contribution formula is:

50 percent of a participant’s base salary deferrals for the year, up to a maximum of five percent of the participant’s base salary, less

the maximum amount of matching contributions that the participant is eligible to receive under the Savings Plan for the year.

NEOs hired before January 1, 2006, are not eligible to receive the 5.25 percent annual contributions described above. A participant’s deferred compensation accounts are credited with returns in

accordance with the deemed investment options, consistent with those offered under the Savings Plan, as elected by the participant from time to time at the participant’s discretion. For 2023, these deemed investment options experienced annual rates of returns of between 1.01 percent and 31.24 percent.

Participants are immediately vested in all contributions to the Employee Deferred Compensation Plan, except for our 5.25 percent annual contributions, which vest, unless otherwise determined by the ED&CC, at the earliest of:

completion of five years of service;

attainment of age 65;

death; or

a change of control.

Participants may elect to receive a distribution of their account balances upon a separation from service or a specified distribution date. Distributions are paid in the form of a lump sum or in annual installments over a period of between two and 10 years.

POTENTIAL PAYMENTS ON TERMINATION OR CHANGE OF CONTROL

This section describes the plans and arrangements that provide for payments to the NEOs in connection with certain events involving termination of employment, a change of control of American Water or a material change in employment responsibilities.

Executive Severance Policy

Our Executive Severance Policy provides severance benefits to executives whose employment is involuntarily terminated by American Water for reasons other than cause, and other than in connection with a change of control of American Water.

The determination of whether an executive’s employment is terminated for cause will be made by the ED&CC or the Board, as applicable. Under the policy, our CEO will receive 18 months, and other NEOs will receive 12 months, of base salary continuation and a pro rata APP award for the year in which the termination of employment occurs to the extent a payment is earned under the terms of the APP.

Eligible executives are entitled to continued Company-paid health, dental and vision coverage based on their years of service, in the amount of: eight weeks of

coverage for less than five years of service; 12 weeks of coverage for at least five years but less than 10 years of service; and 16 weeks of coverage for 10 or more years of service. They are also entitled to life insurance coverage and continued participation in the employee assistance plan for the number of months of their severance benefits, as well as 12 months of outplacement services. Executives also receive credit for their severance period for purposes of vesting under any applicable nonqualified deferred compensation or defined benefit retirement plans. In order to receive severance benefits under the Executive Severance Policy, an executive must sign a release and waiver of any claims against American Water and agree to certain restrictive covenants. Severance benefits payable under the Executive Severance Policy will be offset and reduced by any other severance benefits payable under any employment agreement or otherwise.

AMERICAN WATER | 2024 PROXY STATEMENT

Change of Control Severance Policy

Our Change of Control Severance Policy provides severance benefits to a NEO whose employment is terminated without “cause” or if the NEO resigns from employment for “good reason,” each within 24 months after the consummation of a change of control. Whether a NEO’s employment is terminated for cause will be determined by the ED&CC or the Board, as applicable. Severance benefits will be payable to a NEO under this policy only if the NEO is not otherwise covered by an agreement that provides for severance benefits in the event of a covered termination of employment. A

summary of the benefits provided under the Change of Control Severance Policy is described in “Compensation Discussion and Analysis—Ongoing and Post-Employment Arrangements and Benefit Plans—Change of Control Severance Policy.” In order to receive severance benefits under the Change of Control Severance Policy, a NEO must sign a severance agreement and general release, waiving any claims against American Water and agreeing to appropriate restrictive covenants dealing with confidentiality, non-solicitation and non-competition.

Annual Performance Plan

Generally, to receive an APP payment, an APP participant must continue to be employed with the Company on the date the award is paid, and a termination of a participant’s employment for any reason will result in a forfeiture of the participant’s award. However, in the

event that a participant (including an NEO) retires from their employment prior to the receipt of an APP payment but after attaining age 55 and 10 years of service, the participant will receive their APP award in full.

Employee Deferred Compensation Plan

A summary of the terms of the Employee Deferred Compensation Plan is provided above under “—Description of the Employee Deferred Compensation Plan.” This section describes the payments that would be made under that plan upon various types of termination. NEOs are immediately vested in all their contributions to the Employee Deferred Compensation Plan, and generally become vested in our 5.25 percent annual contributions at the earliest of completion of five years of service, attainment of age 65, a change of

control or death. A participant who is terminated for other than cause will receive the participant’s vested portion of their account balance. Upon a termination for cause, all employer contributions to this plan would be forfeited by the participant, but the participant would still be entitled to their elective deferrals and related income. Payments of vested amounts will be made at the time and in the form elected by the participant, except that a lump-sum distribution of vested amounts will be paid upon death.

AWWPP and ERP

Our retirement plans are described above under “—Description of Pension and Other Retirement Plans.” This section describes the payments that would be made under the retirement plans upon various types of termination of employment.

Voluntary and involuntary terminations of employment— Ms. Norton would have been entitled to benefits from the AWWPP and the ERP upon voluntary or involuntary termination of employment at December 31, 2023. Ms. Norton’s annual AWWPP benefit, payable as a 50 percent joint and survivor annuity beginning at age 59, is $159,241 as of December 31, 2023. Ms. Norton would also have received an ERP lump sum benefit of $5,126,104 as of December 31, 2023.

Retirement—At December 31, 2023, Ms. Norton was eligible for early retirement benefits under both the AWWPP and the ERP.

Disability—Benefits payable upon a termination of employment as a result of a disability are determined under the AWWPP and the ERP in the same manner as benefits payable upon early retirement, except that disability benefits are payable immediately and without reduction for early commencement. AWWPP benefits are payable as annuities; ERP disability benefits are payable as lump sums unless the participant has elected an alternate form of payment. Ms. Norton has completed the required 10 years of service to qualify for disability benefits of her respective plans.

LOGO

AMERICAN WATER | 2024 PROXY STATEMENT

Death—In the event of death on December 31, 2023, Ms. Norton’s surviving spouse or named beneficiary would have received benefits under the AWWPP and/or the ERP (as applicable) calculated as if they had immediately elected a 100 percent joint and survivor annuity. The benefit under the AWWPP would have been equivalent to that payable as an immediate annuity based on Ms. Norton’s current age early retirement factor, in the form of a 100 percent joint

and survivor annuity based on her and her survivor’s current age. The benefit under the ERP for Ms. Norton would have been paid as the immediate lump-sum equivalent of an annuity determined in the same manner as under the AWWPP.

For purposes of reporting these benefits in the termination table below, we reflected that Ms. Norton is married and we used her spouse’s actual age.

Equity Awards

In the event of a change of control in which American Water is not the surviving entity, the 2017 Omnibus Plan requires that all unexercised options and other grants of awards thereunder be assumed by or converted to similar options or awards of the acquirer company. To the extent any such options or awards are not assumed or converted, then all such options become fully exercisable, all restrictions upon awards will lapse and all stock units will fully vest, upon the change of control.

If a grant is assumed in connection with a change of control, and if, within the 12-month period following the occurrence of such change of control, the participant ceases to be employed by, or providing service to, the surviving corporation (or a parent or subsidiary of the surviving corporation) on account of:

a termination of such participant’s employment by the surviving corporation (or a parent or subsidiary of the surviving corporation) for any reason other than due to cause (as defined in the 2017 Omnibus Plan), death or disability (as defined in the 2017 Omnibus Plan), or

a termination of employment or service by the participant for good reason (as defined in the 2017 Omnibus Plan),

then as of the date of such termination of employment or service:

all awards will be accelerated;

all restrictions and conditions upon awards will lapse; and

all stock units will be fully vested.

Notwithstanding the foregoing, in the event of a change of control, the ED&CC may take any of the following actions with respect to any outstanding grants:

accelerate all outstanding options;

lapse all restrictions and conditions on outstanding stock awards;

vest all outstanding stock units;

require participants to surrender their outstanding options in exchange for payment;

terminate any unexercised options after giving participants an opportunity to exercise their options; and

determine that participants receive a payment in settlement of outstanding stock awards, stock units, dividend equivalents or other stock-based awards.

The ED&CC has granted long-term equity awards under the 2017 Omnibus Plan to persons serving in the CEO, CFO and COO roles to provide for continued vesting of these equity awards after retirement under certain circumstances. For further information, see “Compensation Discussion and Analysis—Ongoing and Post-Employment Arrangements and Benefit Plans—Terms of Outstanding Equity Grants” on page 43 of this proxy statement.

Quantification of Potential Payments on Termination or Change of Control

The following tables quantify the potential payments and benefits to which the NEOs would have been entitled to receive if one of several different termination of employment or change of control events occurred on December 31, 2023.

The amounts shown in the tables do not include certain payments and benefits to the extent they are

provided on a non-discriminatory basis to non-union employees generally upon a termination of employment, including accrued salary and vacation pay, Savings Plan benefits, continued health and welfare coverage following an involuntary termination of employment and coverage under COBRA (other than the payment by the Company of a NEO’s COBRA

premiums). All employees are also entitled to life insurance benefits of up to 1.5 times base salary, up to a maximum amount of $200,000, if death occurs while actively employed, which benefit is also not included in the tables below. The amounts shown in each table for “APP” are based on target performance. The amounts shown in each table below for “Deferred Compensation Benefits” reflect the value of employee and employer contributions in each NEO’s employee deferred compensation plan account as of December 31, 2023, and any acceleration of benefits provided under the terms of the Employee Deferred Compensation Plan, the Executive Severance Policy or the Change of Control Severance Policy.

With regard to the portion of RSUs subject to a continuation or acceleration of vesting at December 31, 2023, the assumed values of such

awards are shown in the table in the applicable columns. With regard to the portion of PSUs subject to performance-based vesting following the continuation or acceleration of time-based vesting, we have assumed that such shares will be issued in respect of the PSUs based on target performance, and that dividend equivalents will continue to accrue through the duration of the applicable performance period. For RSUs and PSUs, the values shown in the tables are based on the number of RSUs or PSUs multiplied by $131.99, the closing price of our common stock as reported on the NYSE on December 29, 2023, the last trading day of the year. In addition, the value of accumulated dividends (and, for awards that remain subject to performance conditions through the end of the performance period, expected dividends for the remainder of the performance period) is included.

The table below sets forth each of the amounts required by SEC rule to be deducted from and added to the amount of total compensation as reflected in the Summary Compensation Table, to calculate executive compensation actually paid. In computing these amounts with respect to PSUs, (i) total fair value (FV) as of

year-end

is based on the updated expected payout of the PSU using data through

year-end

The identity of the companies, and the analysis utilized by the ED&CC to review and approve changes, in the peer group for 2023, 2022, 2021 and 2020 are incorporated by reference from the descriptions contained in “—Compensation Discussion and Analysis—Compensation Determinations and Pay Competitiveness” in this proxy statement and in the corresponding sections of our 2022 and 2021 proxy statements. The peer groups for 2021 and 2020 were comprised of the same companies as for 2022, except that MDU Resources Group, Inc. had been included for 2021 and 2020 and was replaced by Essential Utilities, Inc. in 2022.

This metric is the Company-Selected Measure, which in our assessment represents the most important financial performance measure we use to link compensation “actually paid” (as defined by SEC rule) in 2023 to our NEOs. Adjusted EPS for 2023, 2022 and 2021 is a non-GAAP measure. See Part A of Appendix A for a reconciliation.

(4)	Ms. Hardwick has been serving as our CEO effective as of February 2, 2022.

(5)

The persons included as NEOs in this calculation for each year are: (i) for 2023 and 2022, Mses. Kennedy and Norton, and Messrs. Gallegos and Griffith; (ii) for 2021, Mses. Kennedy, Hardwick and Norton, and Adam Noble and Michael A. Sgro; and (iii) for 2020, Ms. Hardwick, and Brian Chin, Bruce A. Hauk, Mr. Sgro and Loyd A. Warnock.

The cumulative TSR reported above for the Company’s peer group for (i) 2023 ($94.14) would have been $92.18 if the companies in the 2022 peer group had been used instead and (ii) 2022 ($106.97) would have been $106.63 if the companies in the 2021 peer group had been used instead. There were no peer group changes that impacted compensation for 2021 or 2020.

(7)	During 2021, Walter J. Lynch was CEO and served as our principal executive officer until his retirement on February 2, 2022.
(8)	Mr. Lynch was CEO as of December 31, 2020, after succeeding Susan N. Story as our principal executive officer upon her retirement effective April 1, 2020.

The following is a tabular list of the most important financial and

*	2021, 2022 and 2023 results reflect Adjusted EPS. See Appendix A for a reconciliation of Adjusted EPS.

Executive compensation “actually paid” (as defined by SEC rule) in the table and graphs above reflects the occurrence of CEO transitions in 2020 and 2022, each of which resulted in the promotion of an existing member of the Company’s executive leadership team. The net income relationship graph above for 2021 also includes the impact of the gain on sale of HOS of $491 million

after-tax,

reflecting the Company’s 2021 contribution to the AWCF and the revaluation of state net operating losses.

CEO PAY RATIO

Pursuant to SEC rules, we are required to disclose in this proxy statement the ratio of the annual total compensation of our CEO to the median of the annual total compensation of all of our employees (excluding the CEO). Our identification of our median employee and our CEO to median employee pay ratio were calculated in a manner we believe to be consistent with Item 402(u) of Regulation

S-K.

In this regard:

We identified the median employee in 2023 by examining the 2023

W-2

earnings for all individuals, excluding Ms. Hardwick, who were employed by us on December 31, 2023. We believe the use of

W-2

earnings represents an objective, easily understood and consistently applied measure of compensation paid across our entire employee base.

We included 6,507 employees located in the United States as of December 31, 2023, which includes full-time, part-time, seasonal and temporary employees. We did not have any employees located outside of the United States as of December 31, 2023.

We did not include leased employees or independent contractors.

We did not make any assumptions, adjustments (such as

cost-of-living

adjustments) or estimates with respect to

W-2

income other than annualizing the compensation of permanent employees that were employed as of December 31, 2023 but were employed for less than the full year.

After identifying the median employee, we calculated that employee’s annual total compensation using the same methodology we use for our NEOs in the 2023 Summary Compensation Table. The annual total compensation for fiscal year 2023 for Ms. Hardwick, determined as described above, and for the median employee was $7,720,825 and $96,531, respectively. The resulting ratio of Ms. Hardwick’s pay to the pay of our median employee for fiscal year 2023 is 80 to 1.

As contemplated by Item 402(u) of Regulation

S-K

and related interpretations, we relied on methods and assumptions that we determined to be reasonable and appropriate for this calculation. Other public companies may use different methods and assumptions. It may therefore be difficult, for this and other reasons, to compare our reported ratio to those reported by other companies.

PROPOSAL 3

RATIFICATION OF APPOINTMENT OF INDEPENDENT

REGISTERED PUBLIC ACCOUNTING FIRM

GENERAL

The Audit, Finance and Risk Committee is directly responsible for the appointment, compensation, retention, evaluation and oversight of the Company’s independent registered public accounting firm. As part of this responsibility, the Audit, Finance and Risk Committee annually evaluates the independent registered public accounting firm’s qualifications, performance and independence and assesses whether to continue to retain the firm or select a different firm.

The Audit, Finance and Risk Committee has appointed the firm of PricewaterhouseCoopers LLP to serve as the independent registered public accounting firm for American Water during the fiscal year ending December 31, 2024. PricewaterhouseCoopers LLP has served as our auditor since 1948. The Audit, Finance and Risk Committee and the Board have recommended that the shareholders ratify this appointment.

The Audit, Finance and Risk Committee and its Chair are also involved in and approve the selection of the lead audit partner, who is limited to no more than five consecutive years in that role before the position must be rotated in accordance with SEC rules. A new audit partner began his five-year rotation in the first quarter of 2023.

The Audit, Finance and Risk Committee and the Board believe that the continued retention of PricewaterhouseCoopers LLP as the Company’s independent auditor is in the best interests of the Company and its shareholders. Although shareholder ratification is not required by our organizational documents, or applicable law, the Board believes that it is a sound corporate governance practice to seek shareholder ratification of the appointment of PricewaterhouseCoopers LLP.

If our shareholders fail to ratify this appointment, the Audit, Finance and Risk Committee may reconsider its selection; however, it is under no obligation to engage a different auditing firm. Even if the selection is ratified, the Audit, Finance and Risk Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if the Audit, Finance and Risk Committee believes that such a change would be in the best interests of the Company and our shareholders.

A representative of PricewaterhouseCoopers LLP is expected to attend the annual meeting virtually and may respond to appropriate questions from shareholders at the meeting or make a statement, if requested.

FEES PAID TO INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The following table presents fees paid to PricewaterhouseCoopers LLP for professional services rendered with respect to 2023 and 2022. All of the services described in the footnotes to the table below were approved in advance by the Audit, Finance and Risk Committee, in accordance with its policy on the pre-approval of services to be provided by our independent registered public accounting firm.

COMMUNICATIONS, SHAREHOLDER PROPOSALS AND COMPANY INFORMATION

SHAREHOLDER COMMUNICATIONS TO THE BOARD

Shareholders and other interested parties may communicate directly with the Board or individual members of the Board, including those wishing to express concerns relating to accounting, internal controls, audit matters, fraud or unethical behavior, by submitting written correspondence to the Company or via email: contacttheboard@amwater.com. The Company’s Secretary reviews and provides summaries and/or copies of the communications to the Board and relevant committees. All communications are treated confidentially. Such communications related to purely contractual, utility or customer relations matters are typically forwarded to appropriate members of management, rather than to the Board.

Our “whistleblower” policy prohibits American Water and any of its employees from retaliating or taking any adverse action against anyone for raising a concern in good faith. If an interested party nonetheless prefers to raise their concern to the Board in a confidential or anonymous manner, the concern may be directed to our confidential ethics hotline at (877) 207-4888 or via the Internet at www.amwater.ethicspoint.com. Such matters raised on the hotline are investigated by the Compliance and Ethics Department.

SHAREHOLDER PROPOSALS, PROXY ACCESS DEADLINES AND DIRECTOR NOMINATIONS

Shareholder Proposals

Except as provided below under “—Proxy Access Deadlines,” any shareholder who, in accordance with SEC Rule 14a-8, wishes to present a proposal for inclusion in the proxy materials to be distributed in connection with the 2025 annual meeting of shareholders must submit the proposal so that it is received by our Secretary at our principal executive offices on or before November 26, 2024, and must comply in all other respects with applicable SEC rules. If the date of the 2025 annual meeting is changed by more than 30 days from the date of the 2024 annual meeting, then the deadline for receipt of the proposal would be a reasonable time before we begin to print and send our proxy materials. Shareholder proposals must be delivered to our Secretary as described under “—Contacting Us or Our Transfer Agent” on page 70 of this proxy statement.

Any shareholder who wishes to propose any business to be considered by the shareholders at the 2025 annual meeting (other than a proposal for inclusion in the proxy statement pursuant to SEC Rule 14a-8), or to nominate a person for election to the Board at that meeting (including via universal proxy or a solicitation

relying on Rule 14a-19 under the Exchange Act), must provide timely and proper notice to American Water in writing, including the specified information described in our Amended and Restated Bylaws concerning the proposed business or nominee and information required by Rule 14a-19.

The requirements for such notice are set forth in our Amended and Restated Bylaws, a copy of which can be obtained from the Company upon request. The notice must be received at American Water’s principal executive offices no earlier than January 15, 2025, and no later than February 14, 2025. However, if the date of the 2025 annual meeting is more than 30 days before or 60 days after May 15, 2025, other than as a result of any adjournment or postponement thereof, notice must be received not later than 90 days prior to the date of the 2025 annual meeting, or, if later, by the 10th day following the Company’s first public announcement of the date of the 2025 annual meeting. The shareholder must otherwise comply with all applicable procedural and substantive requirements set forth in our Amended and Restated Bylaws.

Proxy Access Deadlines

Our Amended and Restated Bylaws permit an eligible shareholder or group of shareholders to include up to a specified number of director nominees in our proxy

materials for an annual meeting of shareholders. See “Board of Directors and Corporate Governance—Proxy Access” on page 14 of this proxy statement.

AMERICAN WATER | 2024 PROXY STATEMENT

As a condition to the use of the proxy access bylaw, the eligible shareholder or eligible group of shareholders and each director nominee must satisfy all of the procedural and substantive requirements specified in the Amended and Restated Bylaws,

DELIVERING PROXY MATERIALS THROUGH ELECTRONIC MEANS

Important Notice Regarding the Availability of Proxy Materials for the Shareholder Meeting

to Be Held on May 15, 2024

The Notice of 2024 Annual Meeting of Shareholders, 2024 Proxy Statement and

2023 Annual Report are available at www.proxyvote.com.

Under the “Notice and Access” rules approved by the SEC, we are permitted to deliver this proxy statement and our 2023 Annual Report by providing access to the documents on the Internet instead of mailing printed copies. In prior years, subject to an individual shareholder’s election to the contrary, we generally provided printed “full set” proxy materials to certain shareholders, while other shareholders instead received a “Notice of Availability” card. This year, subject to a shareholder’s contrary election, each shareholder will receive a Notice of Availability card in lieu of “full set” materials. Although the Notice of Availability identifies the items to be voted on at the meeting and how to vote, a shareholder cannot vote shares merely by marking the Notice of Availability and returning it. However, if a shareholder has previously requested a paper copy of our proxy materials (and the request has not been revoked) or if delivery of printed proxy materials is required by law, the shareholder will

receive a printed copy of the proxy materials instead of the Notice of Availability.

Beginning on the date of mailing of the Notice of Availability, shareholders will be able to access all of the proxy materials on a website referred to in the Notice of Availability. If you received a Notice of Availability and would like to receive free of charge a paper or electronic copy of our proxy materials, you may elect to do so by following the instructions in the Notice of Availability for requesting such materials.

To the extent we are not required by law to mail our proxy materials to you in paper form, you can eliminate all such future paper mailings, including mailing of the Notice of Availability, by electing to receive an e-mail that will provide Internet links to these documents and the online proxy voting website. Opting to receive all future proxy materials

HOUSEHOLDING OF PROXY MATERIALS

To reduce the expense of delivering duplicate sets of proxy materials to multiple shareholders sharing the same address, we have adopted a procedure approved by the SEC called “householding.” This procedure saves printing costs and postage fees, and conserves natural resources.

Under the householding procedure, certain shareholders of record who have the same address and last name will receive only one copy of the Notice of Availability and/or set of proxy materials, unless one or more of the shareholders at that address has previously elected to receive separate copies.

Under the SEC’s householding rules, intermediaries also may deliver a single copy of the proxy materials or Notice of Availability to two or more shareholders that share the same address. If you and other residents at your mailing address own shares of common stock in street name through a broker or bank, you may have received a notice that your household will be sent only one copy of the proxy materials or the Notice of Availability. If you did not provide your broker or bank with notice that you object to this householding, you may have been deemed to have consented to the householding of information. However, upon written or oral request, we will promptly deliver a separate copy of the annual report and/or proxy statement to any shareholder at a shared

address to which a single copy of each document was delivered.

To change your householding status with respect to your shares of common stock:

if you are the registered holder of your shares, please contact Equiniti Trust Company, LLC, our transfer agent, as noted below in “—Contacting Us or Our Transfer Agent” or

if you hold your shares in street name, please contact Broadridge Financial Solutions:

by telephone, toll-free, at (866) 540-7095 or

in writing, at 51 Mercedes Way, Edgewood, New York 11717, Attention: Householding Department.

If you are a shareholder currently sharing an address with another of our shareholders and wish to have your future proxy materials householded, or your materials are currently householded and you would prefer to receive separate materials in the future, please make a request to change your householding status, as indicated above. We encourage shareholders to have all the shares they hold of record registered in the same name and under the same address.
