Dear American Water Shareholder:

I am pleased to welcome you to American Water's Annual Meeting of Shareholders on Wednesday, May 10, 2023, which will be conducted virtually in order to maintain a safe and secure meeting environment and to provide broad meeting access for our shareholders and employees.

The Board is pleased to recognize the Company's ongoing leadership and successes in a number of key areas. For 2022, the Company delivered strong financial and operating results, driven by continued growth in its regulated businesses from infrastructure investment, acquisitions and organic growth. The Board also continues to be proud of the Company's environmental leadership, as demonstrated by American Water's adoption in 2022 of science-based scope 1 and 2 greenhouse gas (GHG) emissions reduction targets aligned with the Paris Agreement, including a net-zero scope 1 and 2 GHG emissions target by 2050. Supporting these new emissions goals, the Company also publicly disclosed scope 3 emissions profile information for the first time.

During 2022, the Company also achieved successes as it progresses on its inclusion, diversity and equity (ID&E) journey. In addition to the many ID&E recognitions received, American Water issued its second annual ID&E report and launched its real-time diversity and inclusion website, called *DiversityatAW.com*. The Board believes these efforts reflect American Water's commitment to sustain the diversity and vibrancy of the many communities it proudly serves across the United States. Finally, the Board demonstrated its steadfast commitment to good corporate governance through Board refreshment, by electing two new directors in December 2022 with diverse skills, leadership and backgrounds in human resources, safety and operational excellence.

This year's proxy statement also recognizes the Company's proactive engagement and dialogue with its shareholders. Throughout the year, the Company solicits feedback as part of its ongoing investor relations and shareholder outreach programs. The Board highly values this constructive and open dialogue, and in direct response to the input received, the Company has further enhanced its proxy disclosures and governance information. For example, this proxy statement includes a director skills matrix, individual director diversity information, and a refreshed visual experience providing investors with the clear and readable information they want and appreciate.

It is important that your shares be represented and your vote counted at the annual meeting. To do so, we encourage you to vote your shares in advance of the meeting by using one of the methods described in the accompanying materials. On behalf of the Board, I thank you for your support and ownership of American Water.

Sincerely,

![LOGO](g432194g02g12.jpg)

ATTENDING THE VIRTUAL ANNUAL MEETING

The health and safety of our shareholders, directors, officers, employees, other attendees, and the public at large, is American Water's most important concern. To promote shareholder safety and security, and to permit broader shareholder access to the meeting, we are holding the meeting solely via remote communications, also known as a "virtual meeting," rather than at a physical location. You will not be able to attend the meeting in person. However, this virtual meeting format will provide shareholders with an opportunity to participate in the meeting as they would at an in-person meeting.

Shareholders may submit questions in advance of the meeting before 11:59 p.m., Eastern time, on Tuesday, May 9, 2023, by going to *www.proxyvote.com*, entering your 16-digit control number set forth on your proxy card, Notice of Availability or voting instruction form, as applicable, and following the instructions to submit a question. We intend to answer at the meeting properly submitted questions that are germane to the matters to be voted on at the meeting, as time permits. However, we reserve the right to exclude any question that is (i) duplicative of another question or not pertinent to meeting matters,

All shareholders of record as of the record date are entitled to vote at the meeting. As of the close of business on the record date, 194,642,848 shares of our common stock were outstanding.

Under our Amended and Restated Bylaws, the holders of a majority of the outstanding shares of our common stock at the close of business on the record date must be present at the meeting, either virtually or by proxy, to constitute a quorum and to transact business at the meeting.

The internet and telephone voting facilities for shareholders of record will close at 11:59 p.m., Eastern time, on Tuesday, May 9, 2023.

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:

&nbsp;&nbsp;&nbsp;&nbsp;· "**FOR**" the election of each of the Board's ten director nominees

&nbsp;&nbsp;&nbsp;&nbsp;· "**FOR**" the approval, on an advisory basis, of the compensation of our named executive officers

&nbsp;&nbsp;&nbsp;&nbsp;· for the approval, on an advisory basis, of an advisory vote **"EVERY YEAR"** on the compensation of our named executive officers

&nbsp;&nbsp;&nbsp;&nbsp;· "**FOR**" the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for 2023

&nbsp;&nbsp;&nbsp;&nbsp;· "**AGAINST**" a shareholder proposal, if properly presented at the meeting

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/AWK2023*, 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 81 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 any of Proposals 1, 2, 3 or 5, 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 4 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/AWK2023*, 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.

REVOKING OR CHANGING A PROXY

If you own shares in your own name (including shares you may hold through American Water Stock Direct, our dividend reinvestment and direct stock purchase plan), you may revoke any prior proxy, regardless of how your proxy was originally submitted, by:

&nbsp;&nbsp;&nbsp;&nbsp;· sending a written statement to that effect to our Secretary, which must be received by us before the meeting;

&nbsp;&nbsp;&nbsp;&nbsp;· submitting a properly signed proxy card dated a later date;

&nbsp;&nbsp;&nbsp;&nbsp;· submitting a later dated proxy via the Internet or by telephone; or

&nbsp;&nbsp;&nbsp;&nbsp;· attending the meeting virtually and voting your shares at the meeting.

Please see "Communications, Shareholder Proposals and Company Information—Contacting Us or Our Transfer Agent" on page 82 of this proxy statement for more information on providing our Secretary with written notice and "—Attending the Virtual Annual Meeting" beginning on page 1 of this proxy statement regarding the requirements for attending the virtual meeting.

If you hold shares in street name, you should follow the instructions provided on the voting instruction form you received from the intermediary or contact the intermediary for instructions on how to change your vote.

BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

THE BOARD OF DIRECTORS

As of the date of this proxy statement, the Board is comprised of 11 members, consisting of 10 independent directors and M. Susan Hardwick, our President and Chief Executive Officer.

The Board held 15 meetings during 2022. During the period in 2022 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 overall attendance during 2022 for all Board members was 94.9 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 2022 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

In October 2022, the Board approved the adoption of amendments to our 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 include 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:

&nbsp;&nbsp;&nbsp;&nbsp;· an executive officer or director of the Company;

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

&nbsp;&nbsp;&nbsp;&nbsp;· 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:

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

&nbsp;&nbsp;&nbsp;&nbsp;· the related person's interest in the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;· 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;

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

&nbsp;&nbsp;&nbsp;&nbsp;· 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 COMMITTEES

As of the date of this proxy statement, the Board has four separately designated standing committees:

![LOGO](g432194g02w21.jpg)

Each standing committee has a charter that governs its operations and sets forth each such committee's duties and responsibilities. A copy of each such committee's charter is available on our Investor Relations website at *ir.amwater.com* and can also be obtained, free of charge, by sending us a written request. See "Communications, Shareholder Proposals and Company Information—Contacting Us or Our Transfer Agent" on page 82 of this proxy statement.

As needed, each standing committee sets a time to meet in executive session without management personnel present. The ED&CC meets regularly with its independent compensation consultant in executive

sessions. The Audit, Finance and Risk Committee meets regularly in separate executive sessions with, among others:

&nbsp;&nbsp;&nbsp;&nbsp;· our Vice President of Internal Audit;

&nbsp;&nbsp;&nbsp;&nbsp;· our General Counsel together with our Chief Compliance Officer; and

&nbsp;&nbsp;&nbsp;&nbsp;· representatives of our independent registered public accounting firm.

Also, each standing committee has the authority to retain outside advisors, including legal counsel or other experts, as it deems appropriate in its sole discretion and to approve the fees and expenses associated with such advisors.

The membership of each of the standing Board committees as of the date of this proxy statement, including the number of committee meetings held during 2022, are set forth in the table below:

Under the terms of its charter, the ED&CC has delegated authority to certain committees comprised of members of management to perform fiduciary, asset administration, and other administrative activities with respect to certain of the Company's retirement and other benefit plans. Also, as authorized by the terms of the Omnibus Plan, the ED&CC has delegated authority to the CEO to grant awards under the Omnibus Plan to Company employees who are not Section 16 officers, subject to an annual maximum number of shares that may be awarded utilizing this delegated authority.

In addition, the Board has designated an Emergency Executive Committee as a non-standing committee of the Board comprised of the Board Chair, as chair, and the chairs of each of the Board's standing committees as other members, to provide for Board action in the event of an emergency or other time-sensitive matter, as determined by the Board. The Emergency Executive Committee is authorized to act on behalf of the Board as to any matter, except as to matters that cannot be delegated to a committee under Delaware law. During 2022, the Emergency Executive Committee met three times.

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 December 2022, to promote gender neutrality, we redesignated the name of this role from "Chairman of the Board" to "Board Chair."

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.

The Board Chair is responsible for:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;· coordinating the work of the Board committees;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;· 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 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.

------

**Executive Development and Compensation Committee Role** 

The ED&CC assesses potential risks related to our compensation policies and practices. 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. This risk assessment is reviewed with both our internal audit function as well as with the Enterprise Risk Management Committee. In February 2022, an update of this risk assessment, which included our 2021 short-term and long-term performance-based executive compensation, was reviewed with the ED&CC. This assessment sought to identify whether features of our compensation policies and practices could potentially encourage excessive risk-taking and whether our risk management objectives are being met with respect to incentivizing our employees.

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:

&nbsp;&nbsp;&nbsp;&nbsp;· base salaries that are a sufficient component of total compensation to discourage excessive short-term risk taking;

&nbsp;&nbsp;&nbsp;&nbsp;· cash performance-based awards with a maximum payout that is limited to 200 percent of target;

&nbsp;&nbsp;&nbsp;&nbsp;· the use of long-term performance awards that mitigate against the taking of short-term risks;

&nbsp;&nbsp;&nbsp;&nbsp;· the implementation of an annual independent audit of our APP targets and award process conducted by our internal audit function;

&nbsp;&nbsp;&nbsp;&nbsp;· the ability of the ED&CC to review progress against APP goals and to exercise discretion in

determining the amount of cash performance- based compensation awarded; <br>

&nbsp;&nbsp;&nbsp;&nbsp;· Company-wide and individual performance targets which are dispersed among a variety of financial and non-financial metrics, as well as among short-term and long-term goals;

&nbsp;&nbsp;&nbsp;&nbsp;· policies and procedures implemented to provide for meaningful checks and balances regarding significant business decisions that may have a compensatory benefit, including the use of a robust vetting process for new business development opportunities and limiting the delegated authority of executives to approve transactions;

&nbsp;&nbsp;&nbsp;&nbsp;· a compensation recovery policy that would require repayment of incentive compensation in the event of a material restatement of our financial statements under specific circumstances;

&nbsp;&nbsp;&nbsp;&nbsp;· the use of overlapping vesting and performance periods through annual long-term performance award grants;

&nbsp;&nbsp;&nbsp;&nbsp;· our long-term performance plan does not include stock options, thereby discouraging behavior focused on short-term increases in stock prices; and

&nbsp;&nbsp;&nbsp;&nbsp;· stock ownership guidelines and retention requirements that are applicable to executives and employees of the Company at a specified minimum salary grade (generally vice president) level.

On the basis of management's review of our executive compensation programs, management concluded, and advised the ED&CC, that the risks of these compensation programs are mitigated and are not reasonably likely to have a material adverse effect on American Water. Accordingly, no material adjustments were made to the Company's compensation policies and practices as a result of its risk profile. The risk assessment for 2022 will be completed and reviewed with the ED&CC in May 2023.

**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.

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 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 CEO

must also submit to the Board annually an emergency succession plan to prepare for any unforeseen event that may prevent the CEO from continuing to serve. 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 limits 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 is able to devote sufficient time to perform their duties as a member of the Board.

Under these provisions, no non-employee director may serve on the board of directors of more than three other public companies, 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. No director may serve on the audit committee of more

than two public companies 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](g432194g00h05.jpg)

As represented by the director tenure graph 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 2022, 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 ninth consecutive year and held both during and after proxy season, shareholders who beneficially owned, in the aggregate, more than 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:

&nbsp;&nbsp;&nbsp;&nbsp;· discussed topics of interest to our shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;· solicited shareholder viewpoints;

&nbsp;&nbsp;&nbsp;&nbsp;· conveyed our views on those topics; and

&nbsp;&nbsp;&nbsp;&nbsp;· 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:

&nbsp;&nbsp;&nbsp;&nbsp;· 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;

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

&nbsp;&nbsp;&nbsp;&nbsp;· accountability for adhering to the Code of Ethics; and

&nbsp;&nbsp;&nbsp;&nbsp;· 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 82 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:

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

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

##### [**Table of Contents**](#toc)
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:

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;· 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 2022 placed us in the top quartile among all of the S&P 500 companies for the fourth year in a row.

The Nominating Committee reviews this policy at least annually and also 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 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, and it may include expenditures for periods of time other than such year. We also have 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. The size of the Board is currently fixed at 11. Ten persons have been named as director nominees for election at the 2023 annual meeting; George MacKenzie will not be standing for re-election at the annual meeting as he does not wish to be considered as a candidate for re-election. Assuming the election of all of the 10 director nominees named in this proxy statement, the Board intends to reset the size of the Board from 11 to 10.

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

&nbsp;&nbsp;&nbsp;&nbsp;· Jeffrey N. Edwards

&nbsp;&nbsp;&nbsp;&nbsp;· Martha Clark Goss

&nbsp;&nbsp;&nbsp;&nbsp;· M. Susan Hardwick

&nbsp;&nbsp;&nbsp;&nbsp;· Kimberly J. Harris

&nbsp;&nbsp;&nbsp;&nbsp;· Laurie P. Havanec

&nbsp;&nbsp;&nbsp;&nbsp;· Julia L. Johnson

&nbsp;&nbsp;&nbsp;&nbsp;· Patricia L. Kampling

&nbsp;&nbsp;&nbsp;&nbsp;· Karl F. Kurz

&nbsp;&nbsp;&nbsp;&nbsp;· Michael L. Marberry

&nbsp;&nbsp;&nbsp;&nbsp;· James G. Stavridis

Each of these nominees is currently a member of the Board. If elected, each nominee would hold office until the date of the 2024 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 10 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 2024 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.

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:

&nbsp;&nbsp;&nbsp;&nbsp;· **Integrity:** Directors must demonstrate high ethical standards and integrity in their personal and professional dealings.

&nbsp;&nbsp;&nbsp;&nbsp;· **Accountability:** Directors must be willing to be accountable for their decisions as directors.

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;· **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.

&nbsp;&nbsp;&nbsp;&nbsp;· **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:

&nbsp;&nbsp;&nbsp;&nbsp;· accounting and finance

&nbsp;&nbsp;&nbsp;&nbsp;· business judgment

&nbsp;&nbsp;&nbsp;&nbsp;· management

&nbsp;&nbsp;&nbsp;&nbsp;· crisis response

&nbsp;&nbsp;&nbsp;&nbsp;· industry knowledge

&nbsp;&nbsp;&nbsp;&nbsp;· utility regulation

&nbsp;&nbsp;&nbsp;&nbsp;· leadership, including in other public companies

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;· environmental management

&nbsp;&nbsp;&nbsp;&nbsp;· ID&E and human capital management

&nbsp;&nbsp;&nbsp;&nbsp;· strategy/vision

&nbsp;&nbsp;&nbsp;&nbsp;· 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:

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

&nbsp;&nbsp;&nbsp;&nbsp;· whether the candidate will effectively, consistently and appropriately take into account and balance the legitimate interests and concerns of all of our shareholders and our other stakeholders in reaching decisions, rather than advancing the interests of a particular constituency;

&nbsp;&nbsp;&nbsp;&nbsp;· whether the candidate possesses a willingness to challenge management while working constructively as part of a team in an environment of collegiality and trust; and

DIRECTOR INDEPENDENCE

The NYSE's listing standards require that:

&nbsp;&nbsp;&nbsp;&nbsp;· a majority of our directors and all of the members of the Nominating Committee satisfy the NYSE's independence standards applicable to all directors;

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

&nbsp;&nbsp;&nbsp;&nbsp;· 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 10 of the 11 directors serving on the Board, consisting of Mses. Goss, Harris, Havanec, Johnson and Kampling, Admiral Stavridis, and Messrs. Edwards, Kurz, MacKenzie and Marberry, qualify as independent. Due to her employment positions 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, MacKenzie 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.

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:

---

|:---|:---|
| <br> &nbsp;&nbsp;&nbsp;&nbsp;Type of Relationship (1)<br>| <br> Description of Relationship (1)(2)<br>|
| <br> &nbsp;&nbsp;&nbsp;&nbsp;Employee or executive officer of American Water | <br> 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.<br>|
| <br> &nbsp;&nbsp;&nbsp;&nbsp;Relationships with internal or external auditor | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br> <u>Any</u> of the following relationships exist:<br> · the director is a current partner or employee of American Water's internal or external auditor<br> · the director has an immediate family member who is a current partner of the internal or external auditor<br> · the director has an immediate family member who:<br> § is a current employee of the external auditor and<br> § personally works on the Company's audit<br> · the director or an immediate family member of the director was, within the last three years:<br> § a partner or employee of the internal or external auditor and<br> § personally worked on the Company's audit within that time<br>|
| <br> &nbsp;&nbsp;&nbsp;&nbsp;Compensation Committee interlocks | <br> 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.<br>|

DIRECTOR EVALUATIONS AND ASSESSMENTS

Each year, directors complete a targeted questionnaire to assess the performance of the Board and each of the standing committees. The questionnaire elicits quantitative and qualitative ratings in key areas of Board operation and function and seeks subjective comments from each director. Each committee member completes questions to evaluate how well the committees on which the member serves are functioning and to provide 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.

DIRECTOR COMPENSATION

As described in the table below, during 2022, 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 $150,000 in equity compensation ($245,000 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:

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp;Director<br>| <br> Annual<br>Cash Retainer |
|  <br> Board Chair<br>| $ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 195000<br>|
|  <br> Audit, Finance and Risk Committee Chair<br>| $140000<br>|
|  <br> ED&CC, Nominating Committee and SETO Committee Chairs<br>| $135000<br>|
|  <br> Other Non-Employee Directors<br>| $115000<br>|

---

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

For calendar year 2022, Semler Brossy Consulting Group LLC, or Semler Brossy, the ED&CC's 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 2022 peer group (as defined below in "Compensation Discussion and Analysis—Compensation Determinations and Pay Competitiveness in 2022" beginning on page 39 of this proxy statement), and that our Board Chair's total compensation was also positioned at the median for non-executive board chairs among the companies in our 2021 peer group with a non-executive board chair.

As a result of the review, and based on, among other things, data and analyses provided by Semler Brossy, in April 2022, the ED&CC recommended, and the independent members of the Board approved, modest increases in certain elements of our director compensation, which brought each element to approximately the 75th percentile of our 2021 peer group, including:

&nbsp;&nbsp;&nbsp;&nbsp;· an increase in the director annual base cash compensation from $110,000 to $115,000;

&nbsp;&nbsp;&nbsp;&nbsp;· an increase in the director annual base equity compensation from $140,000 to $150,000; and

&nbsp;&nbsp;&nbsp;&nbsp;· an increase in the cash and equity premiums paid to our non-executive Board Chair from $72,500 and $87,500, respectively, to $80,000 and $95,000, respectively.

Each of these compensation decisions were effective as of May 11, 2022.

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, or in accordance with the director's irrevocable election to defer distribution of all of their shares of common stock to a later time.

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 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.

PROPOSAL 2

VOTE TO APPROVE, ON AN ADVISORY BASIS, THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

BACKGROUND OF THE PROPOSAL

Section 14A of the Securities Exchange Act of 1934, as amended, or the Exchange Act, requires that our shareholders receive the opportunity to vote to approve, on an advisory (non-binding) basis, the compensation of our named executive officers, or NEOs, as disclosed in this proxy statement in accordance with the SEC's rules. The disclosures related to compensation of our NEOs consist of the Compensation Discussion and Analysis, or CD&A, the 2022 Summary Compensation Table, and the other required executive compensation tables and related narrative disclosures in this proxy statement. In accordance with the advisory vote of our shareholders at our 2017 annual meeting of shareholders, we are providing to our shareholders the opportunity to vote annually to approve, on an advisory basis, the compensation of our NEOs.

Our executive compensation philosophy and programs are designed to create a positive correlation of pay to performance and reward our NEOs for delivering results without incentivizing excessive risk-taking. We seek to attract, motivate and retain high-caliber executives and to align the interests of those executives with the interests of our shareholders in order to build long-term, sustainable value for our shareholders.

Accordingly, the Board recommends that our shareholders vote "FOR" the following resolution:

**RESOLVED**, that the shareholders of American Water Works Company, Inc. (the "Company") approve, on an advisory basis, the compensation of the Company's named executive officers, as disclosed pursuant to the compensation disclosure rules of the U.S. Securities and Exchange Commission, including the Compensation Discussion and Analysis, the executive compensation tables and the related narrative discussion in the Company's proxy statement for the 2023 annual meeting of shareholders.

While the vote is not binding on us, the ED&CC values the opinions expressed by our shareholders and will carefully consider the outcome of the vote when making future compensation decisions for our NEOs. Unless the Board modifies its policy on the frequency of holding this vote, the advisory vote is currently held every year, and the next vote on the frequency of the advisory vote will occur at the 2023 annual meeting of shareholders.

PROPOSAL 3

ADVISORY VOTE ON THE FREQUENCY OF THE ADVISORY VOTE ON

THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

BACKGROUND OF THE PROPOSAL

In accordance with Section 14A of the Exchange Act, the Board is also asking our shareholders to vote, on an advisory (non-binding) basis, on how frequently we should conduct an advisory shareholder vote to approve the compensation of our NEOs.

After careful consideration of the frequency alternatives, our Board has determined that conducting an advisory vote on executive compensation every year is the most appropriate alternative for the Company. The Company's practice historically has been to hold the advisory vote on executive compensation every year and the Board believes the annual vote has worked well. The annual vote gives shareholders the opportunity to provide us with their direct input on our compensation for NEOs every year and the Board believes that an annual vote best enables us to continue to obtain shareholder views on a reasonably current basis.

Shareholders may cast an advisory vote on the frequency of our advisory shareholder vote by choosing one option among (1) every year, (2) every two years, (3) every three years or (4) abstaining from voting, in response to the resolution set forth below.

**RESOLVED**, that a vote of the holders of the common stock of American Water Works Company, Inc. (the "Company") to approve, on an advisory basis, the compensation of the Company's named executive officers, as disclosed pursuant to the compensation disclosure rules of the U.S. Securities and Exchange Commission, including the Compensation Discussion and Analysis, the compensation tables and the narrative discussion contained in the Company's proxy statement, be held at an annual meeting of the shareholders, beginning with the 2023 annual meeting of shareholders, (1) every year, (2) every two years or (3) every three years.

The Board will carefully consider the outcome of the vote when making future decisions regarding the frequency of advisory votes on executive compensation. However, because this vote is advisory and not binding, the Board may decide that it is in the best interests of the Company and its shareholders to hold an advisory vote more or less frequently than the alternative that has been selected by our shareholders.

------

RECOMMENDATION OF THE BOARD

The Board unanimously recommends the approval, on an advisory basis, of an advisory vote **EVERY YEAR** to approve the compensation of our NEOs.

------

COMPENSATION COMMITTEE REPORT

The ED&CC has reviewed and discussed with our management the Compensation Discussion and Analysis, or CD&A, required by Item 402(b) of Regulation S-K. Based on this review and discussion, the ED&CC recommended to the Board that the CD&A be included in this proxy statement.

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 2022, who are:

&nbsp;&nbsp;&nbsp;&nbsp;· M. Susan Hardwick, our President and Chief Executive Officer effective February 2, 2022, who also served as our Chief Financial Officer until May 16, 2022;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;· Walter J. Lynch, who retired effective February 2, 2022, as President and Chief Executive Officer;

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

EXECUTIVE SUMMARY

**Compensation Philosophy** 

Our executive compensation program is designed to:

&nbsp;&nbsp;&nbsp;&nbsp;· reward our NEOs for delivering results without taking excessive risks;

&nbsp;&nbsp;&nbsp;&nbsp;· correlate actual pay realized by our NEOs to our short- and long-term performance;

&nbsp;&nbsp;&nbsp;&nbsp;· align our APP performance measures with our core strategies of safety, customers, growth, operational excellence and people, all of which incorporate our ESG principles;

&nbsp;&nbsp;&nbsp;&nbsp;· align the interests of our shareholders and NEOs; and

&nbsp;&nbsp;&nbsp;&nbsp;· attract, motivate and retain highly qualified executives by providing compensation that is comparable to other companies we compete with for executive talent.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;· annual base salary;

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

&nbsp;&nbsp;&nbsp;&nbsp;· 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 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 and benchmarking data for a NEO's position.

The following graphs depict 2022 total direct compensation mix for our CEO and, on an average basis, for all of our other NEOs as a group, assuming annual and long-term incentive awards are paid at target levels:

**Return to Shareholders** 

We have returned significant value to our shareholders over the past five years. The following stock performance graph shows how a $100.00 investment in our common stock on December 29, 2017, would have grown to $181.51 on December 30, 2022,

assuming quarterly dividend reinvestment. This return compares favorably to the return that would have been obtained through the same investment in the S&P 500 Index and the PHLX Utility Sector Index, assuming dividend reinvestment, during the same period.

SHAREHOLDER ADVISORY VOTES

At our 2022 annual meeting of shareholders, the shareholders approved, on an advisory basis, the compensation paid to our NEOs in 2021, as disclosed under the compensation disclosure rules of the SEC, including the CD&A, the executive compensation tables and the related narrative discussion in the proxy statement for the 2022 annual meeting of shareholders. Often referred to as the "say-on-pay vote," the shareholder vote in favor of NEO compensation was approximately 90.4 percent of the shares deemed present virtually or by proxy and eligible to vote at the meeting.

We consider this vote to be a favorable endorsement of our executive compensation program, practices and policies. Based upon this support, the ED&CC did not believe that any corresponding action or change in our compensation program was needed for 2022.

At our 2023 annual meeting, we will again hold our say-on-pay advisory vote, as well as an advisory vote on the frequency of the say-on-pay shareholder advisory vote. In making executive compensation

decisions, the ED&CC will continue to consider the results of these advisory votes, as well as feedback obtained from shareholders throughout the course of the year.

COMPENSATION DETERMINATIONS AND PAY COMPETITIVENESS IN 2022

For 2022, 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 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.

During 2022, the ED&CC engaged Semler Brossy as its independent compensation consultant. Semler Brossy attended ED&CC meetings, provided analyses of each NEOs compensation as compared to external survey data and the compensation of corresponding NEOs of our peer group, and discussed executive compensation trends.

Through its review of relevant benchmarking data, 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 compensation peer group is also used to compute the three-year relative TSR for our PSUs with vesting tied to this metric. 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.

The composition of our compensation peer group is reviewed by Semler Brossy and is reassessed annually by the ED&CC 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 October 2022, the ED&CC performed its annual reassessment of our peer group looking at relative total assets, market capitalization and total revenues, among other factors. In connection with this review, and to maintain our current positioning, the ED&CC

approved the removal of UGI Corporation from, and the addition of Public Service Enterprise Group Incorporated to, our peer group for 2023 compensation decisions.

2022 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. We believe our program's performance measures align the interests of our shareholders 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 2022:

&nbsp;&nbsp;&nbsp;&nbsp;· 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;· 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

&nbsp;&nbsp;&nbsp;&nbsp;· align NEO and shareholder interests by requiring consistent, meaningful equity ownership.

------

**Base Salaries** 

For 2022, the following were the key annual base salary determinations for our NEOs:

&nbsp;&nbsp;&nbsp;&nbsp;· Effective February 2, 2022, in connection with her promotion to CEO, Ms. Hardwick's base salary for 2022 was set at $1,000,000.

&nbsp;&nbsp;&nbsp;&nbsp;· Effective May 16, 2022, Mr. Griffith's base salary for 2022 was set at $725,000 when he joined as CFO.

&nbsp;&nbsp;&nbsp;&nbsp;· Effective March 7, 2022, Ms. Norton's base salary for 2022 was increased by 23.7 percent to $618,600, reflecting both merit and market

adjustments for positive performance as COO and to bring her base salary within the competitive ranges of the benchmarking data.

&nbsp;&nbsp;&nbsp;&nbsp;· Effective April 1, 2022, Mr. Gallegos's base salary for 2022 was set at $600,000 when he joined as General Counsel.

&nbsp;&nbsp;&nbsp;&nbsp;· Effective March 7, 2022, Ms. Kennedy's base salary for 2022 was increased by 5.8 percent to $438,000, reflecting both merit and market adjustments for positive performance as CHRO and to maintain her base salary within the competitive ranges of the benchmarking data.

**Bonus** 

In 2022, as part of the aggregate consideration for his transition to the Company and, in part, to replace the equity he forfeited when he resigned from his prior employer, Mr. Griffith received a one-time cash sign-on

bonus of $950,000. Mr. Gallegos also received a one-time cash sign-on bonus of $100,000. These amounts have been shown in the "Bonus" column of the Summary Compensation Table.

**2022 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 2022 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. Information used to calculate the 2022 APP award payouts for each NEO is included in the table below.

| M. Susan Hardwick | 110% | $&nbsp;&nbsp;&nbsp;&nbsp;1100000 | 121.4% | $&nbsp;&nbsp;&nbsp;&nbsp;1335400 |
|  John C. Griffith | 100% | $456852 | 121.4% | $554618 |

(1) Mr. Lynch was not eligible for and did not receive a 2022 APP award opportunity due to his retirement on February 2, 2022.

(2) Other than with respect to Ms. Hardwick, prorated for the NEO's base salary throughout the year.

For 2022, in connection with her promotion to CEO, Ms. Hardwick's APP target was increased from 100 percent to 110 percent of her base salary. Ms. Kennedy's 2022 APP target was increased from 55 percent to 65 percent of her base salary to maintain her total direct compensation within the competitive ranges of the benchmarking data.

The 2022 APP targets for Messrs. Griffith and Gallegos were set by the ED&CC at 100 percent and 75 percent of base salary, respectively, when they joined the Company, to align their total direct compensation within the competitive range of the benchmarking data for their respective positions.

The APP performance measures selected for 2022 represent our primary objective for financial performance and are aligned with our 2022 core business strategies of safety, customers, people, operational excellence (in this case, environmental leadership) and growth. As in 2021, APP performance measures for 2022 included EPS, customer satisfaction, ORIR, DART injury rate, drinking water

program compliance and drinking water quality. For 2022, to support our commitment to inclusion, diversity and equity, two new people-related goals were added to the APP: female workforce representation and racial/ethnic diversity workforce representation. Each of these goals was allocated 2.5 percent of the overall APP weighting.

The maximum payout for each of the performance measures set forth in the table below was set at 150 percent of target, except for the EPS performance curve, 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. As in prior years, no payouts would have been earned under the 2022 APP if EPS was less than 90 percent of target.

Our focus on operational excellence is represented by the environmental leadership goals. For 2022, as in 2021, the environmental leadership goal was divided into two equally weighted parts to reflect our strategic focus on both environmental compliance and drinking water quality.

##### [**Table of Contents**](#toc)
The ED&CC determines the payout for APP awards using a corporate performance multiplier. The final percentage for each measure used to determine the corporate performance multiplier was dependent on actual performance with regard to that measure as determined by the ED&CC as soon as reasonably practicable after the end of the year. The corporate performance multiplier 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 for purposes of computing APP 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.

The following table presents information regarding each of the performance measures used to determine the corporate performance multiplier, including the threshold, target and maximum performance requirements for each measure. The table also indicates the percentage that would be included in the corporate performance multiplier for threshold, target and maximum performance.

If the threshold performance requirement for a performance measure is not met, no additional percentage would be included in the corporate performance factor for that measure.

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. |

(1) Adjusted EPS is a non-GAAP measure. See Part A of Appendix A for a reconciliation. No APP awards would have been earned if 2022 EPS was less than 90 percent of the target amount.

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

(3) This goal was not earned because the threshold performance for both female representation and racial/ethnic workforce diversity representation goals was not met.

##### [**Table of Contents**](#toc)
For 2022, the ED&CC determined that the APP awards should be based solely on the NEO's target award multiplied by the corporate performance multiplier based on the CEO's recommendation that NEOs should assume principal responsibility for, and their awards should be determined by reference to, the performance of the entire organization.

Based upon our performance with regard to the financial and non-financial performance measures described above, the ED&CC certified a corporate

performance multiplier of 121.4 percent. The APP awards for each NEO were computed using this multiplier. Cash awards under the APP are generally paid to participants by March 15 of the year following the performance year. We have included the amount of the APP awards paid to our NEOs with respect to 2022 under the Non-Equity Incentive Plan Compensation column of the 2022 Summary Compensation Table on page 52 of this proxy statement.

------

**2022 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 2022 were allocated equally between shares that may be earned based on TSR relative to the companies in the 2022 peer group and shares that may be earned based on the rate of our compounded EPS growth. Stock options are 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; 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 49 of this proxy statement.

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 2022 to each NEO. Information regarding the number of shares underlying these awards is found in "Executive Compensation—2022 Grants of Plan-Based Awards" on page 55 of this proxy statement.

(1) Mr. Lynch was not eligible for and did not receive a 2022 LTPP award due to his retirement on February 2, 2022.

(2) In 2022, as part of the aggregate consideration to replace the equity he forfeited when he resigned from his prior employer to join the Company as General Counsel, and as a term of his employment offer letter, Mr. Gallegos received a one-time RSU grant under the 2017 Omnibus Plan with an aggregate grant date fair value of $1,000,039 and a three-year vesting period. This award has been excluded from this table but has been included in the "Stock Awards" column of the Summary Compensation Table.

In February 2022, in connection with her promotion to CEO, Ms. Hardwick's LTPP award target for 2022 as a percentage of her annual base salary was increased to 400 percent. Ms. Norton's LTPP award target for 2022 as a percentage of her annual base salary was increased, effective February 15, 2022, from 150 percent to 175 percent to bring her compensation within the competitive range of the benchmarking data for her role. Effective February 15, 2022, Ms. Kennedy's LTPP award target for 2022 as a percentage of her annual base salary was increased from 115 percent to 120 percent, to maintain her

compensation within the competitive ranges of the benchmarking data for her role.

Mr. Griffith's and Mr. Gallegos's initial LTPP award targets were set at 250 percent and 160 percent, respectively, to position their total direct compensation within the competitive range of the benchmarking data for their respective positions.

The following table presents information regarding the performance measures related to the PSUs granted in 2022.

| Performance<br> Measure | Threshold<br>Performance<br>(Weighting) | Target<br>Performance<br>(Weighting) | Maximum<br>Performance<br>(Weighting) | How We Calculate the<br> Performance Measure | Why We Use<br> this Performance Measure |
| Relative Total Shareholder Return | 25th<br>percentile<br>(25%) | 50th<br>percentile<br>(100%) | 90th<br> percentile(200%) | Based on American Water's total shareholder return compared to the total shareholder return performance of the companies in the 2022 peer group, during the three-year performance period from January 1, 2022, through December 31, 2024, assuming reinvestment of dividends during the performance period. | This metric enables us to encourage performance that not only increases shareholder value but also increases it to an extent that compares favorably relative to the companies in the 2022 peer group. |
| Compounded EPS Growth Rate | 4.0%<br> (0%) | 5.0%<br> (100%) | 8.0%<br> (200%) | Based on the rate of EPS growth, compounded annually over the three-year period from January 1, 2022, through December 31, 2024, over our 2021 EPS, as adjusted to eliminate the contribution of HOS. | EPS is a key measure of our financial and operational success, and achieving our earnings and strategic goals creates long-term shareholder value and provides greater total return to our shareholders. |

**Performance Vesting of PSUs Granted in 2020** 

In 2020, 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 2020 peer group, and the other with a three-year performance measure based on the annual rate of compounded adjusted EPS growth. The payouts of the two types of PSUs are summarized in the table below:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| Performance Measure | Threshold<br> Performance<br> (Weighting) | Target<br> Performance<br> (Weighting) | Maximum<br> Performance<br> (Weighting) | Actual<br> Performance | &nbsp;&nbsp;&nbsp;&nbsp;Percentage of&nbsp;&nbsp;&nbsp;&nbsp;<br>Target Award<br> Earned |
| Relative Total Shareholder Return | 25th<br> percentile(25%) | 50th<br>percentile<br>(100%) | 90th<br>percentile<br>(200%) | 100th<br>percentile | 200.0% |
| Compounded Adjusted EPS Growth Rate | 6.0%<br> (0%) | 8.0%<br> (100%) | 10.0%<br> (200%) | 9.67% | 191.8% |

---

Actual performance is based on the rate of EPS growth, compounded annually over the three-year period from January 1, 2020 through December 31, 2022, over our 2019 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 2020 (and 2021) PSU awards based on

our compounded EPS growth. See "Executive Compensation—2022 Summary Compensation Table— Modification of 2020 and 2021 PSU Awards During 2022" beginning on page 54 for a discussion of these amendments and adjustments.

The ED&CC certified the achievement of the requisite PSU performance measures in February 2023.

**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.

Our NEOs are also eligible for certain benefits that are generally available to all other salaried, non-union employees, including participation in our qualified

401(k) savings plan with an employer matching contribution (and, for participants hired or rehired after January 1, 2006, 5.25 percent Defined Contribution Account employer contributions), medical insurance coverage, term life insurance coverage, and short-term and long-term disability insurance coverage.

CEO TRANSITION

Upon the retirement of Mr. Lynch as President and Chief Executive Officer of the Company on February 2, 2022, the Board elected Ms. Hardwick to serve as the Company's President, Chief Executive Officer and Chief Financial Officer. Ms. Hardwick had joined the Company in June 2019 and served as the Company's Chief Financial Officer from July 1, 2019, until the election of Mr. Griffith as our Chief Financial Officer effective May 16, 2022.

In connection with her promotion to President and Chief Executive Officer, we entered into a new employment offer letter with Ms. Hardwick effective February 2, 2022. This offer letter described the terms of her CEO compensation and was consistent in form and content with employment offer letters we have historically provided to our NEOs. In addition to the

terms described above, which provided for base salary, APP and LTPP awards, the employment offer letter included a $100,000 cash stipend for Ms. Hardwick's prior service as Interim Chief Executive Officer. The employment offer letter was approved by the independent members of the Board upon the recommendation of the ED&CC, which reviewed data and analyses provided by Semler Brossy.

In connection with Mr. Lynch's retirement and based on the recommendation of the ED&CC, the independent members of the Board authorized the execution and delivery of a Separation and General Release Agreement with Mr. Lynch. See "Executive Compensation—Potential Payments on Termination or Change of Control" on page 65 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, which are expressed as a multiple of

annual base salary, require executives (directly or through immediate family members or controlled entities) to hold a specified amount of common stock (including certain equivalents) based on the executive's position, as follows:

---

| | |
|:---|:---|
| &nbsp;&nbsp; Officer Level | Multiple of Annual Base Salary |
| &nbsp;&nbsp; Chief Executive Officer | 6 times |
| &nbsp;&nbsp; Chief Operating Officer | 3 times |
| &nbsp;&nbsp; Executive Vice Presidents | 3 times |
| &nbsp;&nbsp; Senior Vice Presidents | 3 times |
| &nbsp;&nbsp; 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 to certain exceptions, each executive must be in compliance with the stock ownership guidelines to

effect such a 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 currently 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.

------

OUR HEDGING POLICY

Our insider trading policy prohibits all directors, officers (including our current NEOs) and employees, including their respective immediate family members and controlled entities, from engaging in any transaction entered into for the purpose of reducing or eliminating the market price risk associated with the ownership of our securities, including any of our equity securities we grant to a covered person as

compensation or that may otherwise be held directly or indirectly by the covered person. These types of transactions are commonly known as "hedging" transactions. For more information on this policy, see "Executive Compensation—Policies Prohibiting Hedging, Pledging, Margining and Short Selling" beginning on page 68 of this proxy statement.

------

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.

------

**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 currently employed 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 100 percent of their APP awards (the amount of such contributions are referred to as "basic contributions"), up to limits determined under the Code.

For a NEO participant hired before January 1, 2006 (for 2022, only Ms. Norton), the matching contribution formula was 50 percent of a participant's basic contributions to the Savings Plan for the plan year, up to a maximum of five percent of the participant's base salary. For NEO participants hired or rehired after January 1, 2006 (for 2022, Mses. Hardwick and Kennedy and Messrs. Griffith and Gallegos), the

matching contribution formula was (a) 100 percent of a participant's basic contributions to the Savings Plan for the plan year up to the first three percent of the participant's base salary plus APP awards, and (b) 50 percent of a participant's basic contributions up to the next two percent of the participant's base salary plus APP awards contributed to the Savings Plan for the plan year. In addition, for NEO participants hired or rehired after January 1, 2006 (for 2022, Mses. Hardwick and Kennedy and Messrs. Griffith and Gallegos), we made additional annual contributions to the NEO's Defined Contribution Account 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 hired 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 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

##### [**Table of Contents**](#toc)
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 current 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 provisions of former executive retirement plans. Ms. Norton is the only current 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, 2022" and "Executive Compensation—Description of Pension and Other Retirement Plans" beginning on page 58 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 base salary and APP awards 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 compensation." Each of our currently employed NEOs is eligible to participate in the Employee Deferred Compensation Plan.

Generally, under the Employee Deferred Compensation Plan, a participant may elect to defer up to 20 percent of salary and up to 100 percent of the award paid under the APP. We provided matching contributions that differ depending on whether the participant was hired by us on or after January 1, 2006. For participants hired after January 1, 2006 (for 2022, Mses. Hardwick and Kennedy and Messrs. Griffith and Gallegos), we provide the matching contribution we would have made for the participant under the Savings Plan with respect to the participant's excess compensation if the excess compensation had been

taken into account. In addition, for these participants, we made a defined contribution that is generally equal to 5.25 percent of the sum of base salary that constitutes excess compensation and the award payable under the APP for the relevant plan year.

For participants hired prior to January 1, 2006 (for 2022, only Ms. Norton), our matching contribution is equal to 50 percent of salary deferrals up to a maximum of five percent of base salary; our contributions are more limited for these participants due to their eligibility to participate in the AWWPP.

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—2022 Nonqualified Deferred Compensation" beginning on page 59 of this proxy statement for additional information.

------

**Executive Severance Policy** 

Under our Executive Severance Policy, we provide severance benefits to our currently employed 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 each of such other currently employed 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. See "Executive Compensation—Potential Payments on Termination or Change of Control" beginning on page 60 of this proxy statement for further information.

##### [**Table of Contents**](#toc)
**Change of Control Severance Policy** 

The Change of Control Severance Policy provides benefits to each of our currently employed 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 currently employed 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 currently employed 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 currently employed 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.

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; however, the Executive Severance Policy remains in effect for NEOs with respect to an involuntary termination of employment without cause other than following a change of control.

See "Executive Compensation—Potential Payments on Termination or Change of Control" beginning on page 60 of this proxy statement for further information.

**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:

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

&nbsp;&nbsp;&nbsp;&nbsp;· in the event of an early retirement, defined as having attained age 55 and five years of service, 75 percent of the award will continue to vest.

All CEO LTPP award grants include these continued vesting provisions. 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.

With respect to LTPP awards granted to Ms. Hardwick in her prior role as Executive Vice President and Chief Financial Officer, we agreed in her CFO employment offer letter that she would be deemed to meet the five years of service requirement if, having achieved the required age, she retires after at least three years of continuous service in the CFO role and uses good faith efforts to identify and develop a successor that is ultimately approved by the CEO and the Board.

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.

##### [**Table of Contents**](#toc)
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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

(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 62 of this proxy statement for further information.

RECOVERY OF INCENTIVE COMPENSATION

In 2010, we instituted a policy governing the recovery of executive incentive compensation. Under the policy, we may recover (in whole or in part) any amounts paid under incentive payments made under our annual and long-term performance plans, including the APP and LTPP, to any executive officer subject to Section 16 of the Exchange Act where: (1) the incentive payment was based upon the achievement of certain financial results that are subsequently the subject of a material restatement of our financial statements; (2) the Board determines that one or more covered executives engaged in knowing or intentional fraudulent or illegal conduct that substantially caused the need for the restatement; and (3) a lower incentive payment would have been made to the covered executive based upon the restated financial results. We may also recover incentive payments described above from a covered executive if that covered executive commits acts of embezzlement, fraud, theft or ethical misconduct. 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.

On October 26, 2022, as required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the SEC issued rules directing stock exchanges to adopt listing standards for the implementation of executive compensation recovery requirements in accordance with the new rules. Once the NYSE has adopted listing standards to implement the new requirements, we will review and amend our existing executive compensation recovery policy accordingly.

TAX AND ACCOUNTING CONSIDERATIONS

**Tax Considerations** 

Under Section 162(m) of the Code, a public company is prohibited from deducting for federal income tax purposes compensation in excess of $1.0 million paid to certain of its executive officers. The ED&CC believes that the income tax impacts of compensation is only one of many other relevant considerations in setting compensation. The ED&CC also believes that the Section 162(m) tax deduction limitation should not be permitted to compromise the Company's ability to design and maintain executive compensation arrangements that, among other things, are intended to attract, retain and motivate talented, high-performing executives, and that are

designed to discourage decision-making focused solely on compensatory consequences and excessive risk-taking.

Section 409A of the Code provides that amounts deferred under nonqualified deferred compensation plans are includible in an employee's income when vested unless certain requirements are met. If these requirements are not met, employees may be subject to additional taxes, interest and penalties. Our nonqualified deferred compensation arrangements are intended to satisfy the requirements of Section 409A.

**Accounting Considerations** 

RSU and PSU awards are accounted for based on their grant date fair value, as determined under ASC 718, which is recognized over the service or vesting period applicable to the grant. Forfeitures are estimated, and

the compensation cost of awards will be reversed if the employee does not remain employed by us throughout the service or vesting period.

(1) Since Mses. Hardwick and Kennedy, and Messrs. Griffith and Gallegos, were hired after January 1, 2006, they are not eligible to participate in the AWWPP or the ERP.

(2) Amounts shown reflect the present value of the accumulated benefit as of December 31, 2022. All amounts for the AWWPP and the ERP were determined using the same interest and mortality assumptions as those used for financial reporting purposes. The following assumptions were used to calculate pension values at the following measurement dates:

· 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 Lump Sums for 2023 for payments expected in 2023 and IRS Prescribed Table for 2024 for payments thereafter.

· In 2021, for discounting annuity payments, we used a discount rate of 2.94 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 2.94 percent and the IRS Prescribed Table for Lump Sums for 2022 for payments expected in 2022 and IRS Prescribed Table for 2023 for payments thereafter.

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 who became eligible for the plan on or after July 1, 2001, but before January 1, 2006, such as Mr. Lynch, with a pension benefit equal to 1.6 percent of final average pay multiplied by years of service.

For participants hired prior to July 1, 2001, including Ms. Norton, the AWWPP provides a grandfathered benefit. For years of service prior to July 1, 2001, the grandfathered benefit is calculated to be:

&nbsp;&nbsp;&nbsp;&nbsp;· 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

&nbsp;&nbsp;&nbsp;&nbsp;· 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

&nbsp;&nbsp;&nbsp;&nbsp;· 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:

&nbsp;&nbsp;&nbsp;&nbsp;· 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

&nbsp;&nbsp;&nbsp;&nbsp;· 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

&nbsp;&nbsp;&nbsp;&nbsp;· 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.

For participants hired on or after July 1, 2001, the grandfathered benefit is calculated to be 1.6 percent of final average pay multiplied by years of service.

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.

Mr. Lynch and Ms. Norton are vested in their 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.

##### [**Table of Contents**](#toc)
**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. Mr. Lynch and Ms. Norton participate in this nonqualified pension plan and are entitled to the greater of the benefits determined pursuant to the restoration formula under the ERP and the benefits determined pursuant to their

prior nonqualified plan formulas (if applicable). Mr. Lynch and Ms. Norton are 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 sum. Mr. Lynch elected to receive his benefits as an annuity. 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 current NEOs hired or rehired on or after January 1, 2006, namely Mses. Hardwick and Kennedy and Messrs. Griffith and Gallegos:

&nbsp;&nbsp;&nbsp;&nbsp;· 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 |

---

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

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

&nbsp;&nbsp;&nbsp;&nbsp;· 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

&nbsp;&nbsp;&nbsp;&nbsp;· 5.25 percent of the NEO's bonus.

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

&nbsp;&nbsp;&nbsp;&nbsp;· 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;· 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 2022, these deemed investment options experienced annual rates of returns of between (37.39) percent and 3.09 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:

&nbsp;&nbsp;&nbsp;&nbsp;· completion of five years of service;

&nbsp;&nbsp;&nbsp;&nbsp;· attainment of age 65;

&nbsp;&nbsp;&nbsp;&nbsp;· death; or

&nbsp;&nbsp;&nbsp;&nbsp;· 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.

##### [**Table of Contents**](#toc)
Eligible executives are entitled to continued 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 the ERP. 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.

------

**Change of Control Severance Policy** 

Our Change of Control Severance Policy was adopted in July 2021 and 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, 2022. Ms. Norton's annual AWWPP benefit, payable as a 50 percent joint and survivor annuity beginning at age 58, is $145,039 as of December 31, 2022. Ms. Norton would also have received an ERP lump sum benefit of $2,564,726 as of December 31, 2022.

##### [**Table of Contents**](#toc)
*Retirement*—At December 31, 2022, Mr. Lynch is receiving early retirement benefits under the ERP and has deferred the receipt of benefits under the AWWPP and 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.

*Death*—If Ms. Norton had died on December 31, 2022, her 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. For Mr. Lynch, the benefits described in the narrative below reflect his actual annuity benefit election for his ERP benefit and other relevant factors.

------

**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:

&nbsp;&nbsp;&nbsp;&nbsp;· 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

&nbsp;&nbsp;&nbsp;&nbsp;· 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:

&nbsp;&nbsp;&nbsp;&nbsp;· all awards will be accelerated;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;· all restrictions and conditions upon awards will lapse; and

&nbsp;&nbsp;&nbsp;&nbsp;· 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:

&nbsp;&nbsp;&nbsp;&nbsp;· accelerate all outstanding options;

&nbsp;&nbsp;&nbsp;&nbsp;· lapse all restrictions and conditions on outstanding stock awards;

&nbsp;&nbsp;&nbsp;&nbsp;· vest all outstanding stock units;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;· 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 49 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 (other than Mr. Lynch) would have been entitled to receive if one of several different termination of employment or change of control events occurred on December 31, 2022. For Mr. Lynch, the narrative below describes the payments and benefits he was entitled to receive in connection with his retirement on February 2, 2022.

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 below for "Defined Compensation Benefits"

reflect the value of employer contributions in each NEO's employee deferred compensation plan account as of December 31, 2022.

With regard to the portion of RSUs subject to a continuation or acceleration of vesting at December 31, 2022, 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 $152.42, the closing price of our common stock as reported on the NYSE on December 30, 2022, 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.

(3) 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 2022 to our NEOs.

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

(5) During 2021, Walter J. Lynch was CEO and served as our principal executive officer until his retirement on February 2, 2022.

(6) The persons included as NEOs in this calculation for each year are: (i) for 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.

(7) The cumulative TSR reported above for the Company's peer group for 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.

(8) Mr. Lynch was CEO as of December 31, 2020, after succeeding Susan N. Stor y as our principal executive officer u pon her retirement effective April 1, 2020.

The following is a tabular list of the most important financial and non-financial measures we use to link compensation "actually paid" (as defined by SEC rule and set forth above) to our NEOs during 2022 to our performance. The Company-Selected Measure is denoted with an asterisk.

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

The ED&CC reviewed a comparison of Ms. Hardwick's total compensation as CEO for fiscal year 2022 as reported in the Summary Compensation Table of this proxy statement (with base salary and related 5.25 percent employer Defined Contribution Account match annualized) to the median annual total compensation of our U.S. employees for the same period. 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:

&nbsp;&nbsp;&nbsp;&nbsp;· We identified the median employee in 2022 by examining the 2022 W-2 earnings for all individuals, excluding Ms. Hardwick, located in the United States who were employed by us on December 31, 2022. 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.

&nbsp;&nbsp;&nbsp;&nbsp;· We included 6,514 employees located in the United States as of December 31, 2022, 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, 2022.

&nbsp;&nbsp;&nbsp;&nbsp;· We did not include leased employees or independent contractors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;· 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, 2022 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 2022 Summary Compensation Table. The annual total compensation for fiscal year 2022 for Ms. Hardwick, determined as described above, and for the median employee was $6,756,423 and $91,262, respectively. The resulting ratio of Ms. Hardwick's pay to the pay of our median employee for fiscal year 2022 is 74 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.

POLICIES PROHIBITING HEDGING, PLEDGING, MARGINING AND SHORT SELLING

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;· 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.

These prohibitions do not apply to the receipt of securities under any of our equity compensation plans or "cashless" exercises of our options in compliance with the 2017 Omnibus Plan or its predecessor plan; however, buying or selling a derivative security with respect to any of these securities is expressly prohibited.

------

Also, our insider trading policy 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.

Moreover, our insider trading policy also 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.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

Mses. Goss, Hagen, Harris, Havanec, Johnson and Kampling served as members of the ED&CC during fiscal year 2022. Ms. Hagen served until the date of the 2022 annual meeting, and Ms. Havanec was appointed to the ED&CC on December 7, 2022. With respect to interlocks and insider participation involving members of the ED&CC during fiscal year 2022:

&nbsp;&nbsp;&nbsp;&nbsp;· None of these individuals was an officer or employee of us or any of our subsidiaries during fiscal year 2022 or any prior fiscal year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;· None of these individuals had any relationship with us or any of our subsidiaries during 2022 pursuant to which disclosure would be required under applicable rules of the SEC pertaining to related person transactions.

&nbsp;&nbsp;&nbsp;&nbsp;· None of our executive officers served on the board of directors or compensation committee of any other entity that has or had one or more executive officers who served as a member of the Board or the ED&CC during fiscal year 2022.

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, 2023. 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.

PROPOSAL 5

SHAREHOLDER PROPOSAL:

RACIAL EQUITY AUDIT

Trillium Asset Management, LLC, as representative of Trillium ESG Global Equity Fund, the shareholder, has requested that we include the proposal below in this proxy statement. The proponent has indicated that the shareholder beneficially owns 32,025 shares of common stock as of the date this proposal was submitted. We will provide the address of the proponent promptly upon the oral or written request of a shareholder. The proponent is responsible for the content of this proposal, for which we and the Board do not accept any responsibility.

Racial Equity Audit

Resolved: Shareholders urge the board of directors to oversee a third-party audit (within a reasonable time and at a reasonable cost) which assesses and produces recommendations for improving the racial impacts of its policies, practices, products, and services, above and beyond legal and regulatory matters. Input from stakeholders, including civil rights organizations, employees, and customers, should be considered in determining the specific matters to be assessed. A report on the audit, prepared at reasonable cost and omitting confidential/proprietary information, should be published on the company's website.

Racial equity audits engage companies in a process that internal actions may not replicate, potentially unlocking value, uncovering blind spots, and examining external impacts.

American Water states it "has a strong commitment to employee inclusion, diversity and equity so that we reflect the customers and communities we serve." Its workforce of 74 percent white, 11 percent Black, 6 percent Latino, 2 percent Asian, and <1 percent Native American and Pacific Islander people fails to reflect the demographics of New Jersey, Pennsylvania, Missouri, Illinois, and California, representing 75 percent of operating revenues and 71 percent of its customers.<sup>1</sup> American Water's diversity reporting is not clear about the level of racial and ethnic diversity that has been achieved at executive committee, named executive officer, and board level. Though the company reports having annual goals to increase diversity, they are not public and shareholders cannot evaluate the efficacy of the initiatives.

American Water is also implicated in an environmental justice controversy in Marina, California, where a third of the residents are low-income and many speak limited English.<sup>2</sup> The company's proposed desalination plant in Marina would not supply any of the treated water to the town, which already contains a landfill, a sewage plant, and a sand mine.<sup>3</sup> In addition, California American Water in Monterey, which includes Marina, was the most expensive water system in the country in 2017 after previously holding ninth place in 2015.<sup>4</sup> We believe the company must consider environmental justice in project planning as it may present ongoing operational and legal risk.

In 2020, former CEO Walter Lynch publicly stated that the company works nationally to pass water privatization legislation and supported H.B. 1416 in Maryland, which community organizations, including the NAACP, opposed.<sup>5</sup> Such legislation may have detrimental impacts to communities of color: Black and Latino communities are likelier

to experience water affordability issues.<sup>6</sup> Maryland's population is 53 percent non-white, with 42.5 percent being Black or Latino, and 27 percent of such communities living below the poverty line.<sup>7</sup> One study examining 500 of the largest community water systems in America attributed privatized water systems as the leading cause of higher water bills and the second dominant factor in affordability issues for low-income communities.<sup>8</sup>

We urge the company to conduct a racial equity audit to examine its total impact and help dismantle systemic racism.

------

AMERICAN WATER OPPOSING STATEMENT

We are committed to business practices that promote inclusion, diversity and equity, or ID&E, and combat systemic racism and its impacts in all aspects of our operations. The issues raised by the proponent in this proposal mirror those in a similar shareholder proposal submitted by the same proponent last year and which failed to receive majority shareholder support. Unfortunately, this year's proposal was submitted despite our proactive and intentional steps taken during 2022 on ID&E, as explained in further detail below, and despite significant and transparent engagement with the proponent and other investors during 2021 and 2022 on these issues. We believe this proposal not only fails to recognize those steps, achievements and engagement, but also includes a number of false and misleading assertions in support.

Through discussions with many of our investors during the past year, during which we candidly discussed and shared our vision for this journey, we believe they appreciated our perspective and the proactive efforts we have taken, especially to enhance our transparency. We are committed to continuing this constructive dialogue with our investors, including the proponent, and to continue to listen and engage meaningfully about the work we are currently doing to understand, focus on, and address issues of racial justice.

For the following reasons, the Board recommends a vote **AGAINST** approval and adoption of this Proposal 5.

**A third-party racial equity audit would be unproductive, duplicative and cost prohibitive** 

We are an owner of highly regulated water and wastewater utilities that operate in 14 jurisdictions with stringent oversight by public utility commissions. These bodies enforce specific laws and regulations that require us, as a regulated monopoly in our service territories, to serve all customers equitably. Public utility commissions examine our policies, processes and actions through open and transparent proceedings in which customers, communities and impacted parties are represented and may actively participate. These proceedings provide oversight that acts as a control against racial injustice and, we believe, serves as an equivalent to a third-party audit process.

Furthermore, no minimum standards have been established for conducting a third-party racial equity

audit and cost estimates we received from independent third party auditors, including those recommended by the proponent, were between $1 million and $4 million. We believe that conducting such an expensive and time-consuming audit without clear and independent standards would be unproductive and an ineffective use of significant financial and management resources. To this point, a racial equity audit would cause us to incur additional costs and duplicate our prior third-party analyses of our pay equity and internal labor market reviews. Moreover, aligned with our efforts to support customer affordability, we do not believe that our customers should bear the cost in rates of duplicative audits and new consultancy engagements.

##### [**Table of Contents**](#toc)
**We believe that many of our shareholders agree that our regulatory oversight and enhanced ID&E activities and transparency make a racial equity audit unnecessary and duplicative** 

The shareholders we engaged with during our 2022 outreach appreciated the additional, voluntary disclosures we made in the first half of 2022 and advised that additional disclosures—coupled with our existing regulatory oversight—would likely contribute to a meaningful understanding of our policies, practices and actions related to racial equity, without the need for another duplicative audit. For example:

&nbsp;&nbsp;&nbsp;&nbsp;· In response to shareholder feedback in connection with and following last year's proposal, including from the proponent, we voluntarily disclosed the following additional information before this year's proposal was received:

§ EEO-1 employment data for 2020 and 2021 and we expect to continue this annual disclosure;

§ Our improvement in diversity at the executive leadership team level;

§ Conclusions and implementation of findings from our third-party pay gap, pay equity, and internal labor market analyses;

§ The inclusion of two new people-related goals in our APP to promote workforce diversity, as discussed in "Compensation Discussion and Analysis—2022 Compensation—2022 Annual Performance Plan" on page 41 of this proxy statement; and

---

| | |
|:---|:---|
| § | Regular updates on our ID&E metrics and progress through *www.DiversityatAW.com*, including data on the gender, racial and ethnic diversity of our workforce, leaders (defined as having at least one direct report), executives (defined as the CEO plus one level of the CEO's direct reports), and the Board. |

---

&nbsp;&nbsp;&nbsp;&nbsp;· During our 2022 engagement season, we received significant positive feedback from many of our key institutional investors on these efforts, as well as on our second annual ID&E report, which we issued in May 2022, and *DiversityatAW.com*, which is used to update quarterly our ID&E metrics and information. Based on this feedback, we believe that many of these investors would agree that a racial equity audit is unnecessary and duplicative.

**We are committed to racial and environmental justice, and listen to and incorporate the views of our community members and other stakeholders** 

The Monterey Peninsula Water Supply Project in the City of Marina, California cited by the proponent both this and last year is one of the most complex, yet open and transparent, projects in our history. Below are some key developments in 2022 with respect to this project:

&nbsp;&nbsp;&nbsp;&nbsp;· In 2022 alone, our California subsidiary held over two dozen meetings and community workshops to gather and understand feedback from community members about the project.

&nbsp;&nbsp;&nbsp;&nbsp;· In October 2022, in response to this community input and to encourage future regional public participation, our California subsidiary announced a phased approach for the construction of the desalination plant, which would limit the number of slant wells initially constructed and reduce the plant's initial water output to 4.8 million gallons per day (mgd) from 6.4 mgd.

&nbsp;&nbsp;&nbsp;&nbsp;· In November 2022, the California Coastal Commission approved the coastal development permits for the phased desalination plant. Further, our California subsidiary agreed to provide a

number of enhanced benefits to the local community, including an expansion of customer affordability programs, ongoing outreach and reporting to the City of Marina, and a $3 million community benefit for the City of Marina residents. While this approval is being challenged, the process is an example of American Water's support for environmental justice efforts in California and beyond. <br>

Contrary to the proponent's assertions, water rates in the Monterey service territory are lower than in neighboring communities. Tellingly, the proponent relies on faulty analysis from Public Water Now, an unabashed detractor of investor-owned water providers, to support its erroneous conclusion. Importantly, we believe that this false "name calling" is neither typical of the constructive, thoughtful engagement we strive to achieve with our long-term investors and the communities in which we serve, nor does it encourage constructive dialogue about important environmental and racial justice issues.

##### [**Table of Contents**](#toc)
**The proponent significantly mischaracterizes relevant diversity data and our position on important environmental and water quality accountability legislation** 

The proponent unfairly cites statewide demographic data to assert that our workforce is not representative of the communities we serve. To the contrary, the demographic data for the **communities we serve** shows that the racial and ethnic diversity of our workforce is closely aligned to the racial and ethnic diversity of the communities we serve across our customer footprint.

By citing in its proposal our support of water quality accountability legislation in Maryland, the proponent fails to explain or understand that:

&nbsp;&nbsp;&nbsp;&nbsp;· Water quality accountability laws serve to **strengthen** community water service infrastructure, a central concern of environmental and racial justice efforts (and an important element of our stated long-term strategy).

&nbsp;&nbsp;&nbsp;&nbsp;· By setting operational standards for all water utilities, including municipal and investor-owned utilities, these laws aim to **improve** the reliability, resiliency and sustainability of water systems, especially those in under-represented and minority

communities, with the goal of ultimately **improving** the protection of public health and the environment for all residents. <br>

&nbsp;&nbsp;&nbsp;&nbsp;· We support legislative efforts, such as those cited by the proponent in Maryland and elsewhere, because they (1) are aligned with the **very capital investments we are making** in pipe and water and wastewater treatment facilities across our footprint and (2) **promote** racial and environmental justice.

&nbsp;&nbsp;&nbsp;&nbsp;· Finally, we couple these prudent investments with diligent cost management, technology enhancements, and support for consolidated tariffs and a variety of low-income and other customer assistance programs, all to **promote and achieve customer affordability**.

Finally, to the extent the proponent believes, as expressed to us during outreach with them, that every company should conduct a racial equity audit, we firmly believe, **for all of the reasons discussed above**, that such a "one-size-fits-all" approach to this issue is neither warranted nor desirable.

Any shareholder who wishes to propose any business to be considered by the shareholders at the 2024 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.

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 11, 2024, and no later than February 10, 2024. However, if the date of the 2024 annual meeting is more than 30 days before or 60 days after May 10, 2024, 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 2024 annual meeting, or, if later, by the 10th day following the Company's first public announcement of the date of the 2024 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.

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, including providing advance notice to us and filing certain information with the SEC. With respect to the 2024 annual meeting, the notice must be provided no earlier than October 30, 2023, and no later than November 29, 2023.

The Nominating Committee will consider qualified director candidate recommendations by shareholders. The recommendation must include the following information:

&nbsp;&nbsp;&nbsp;&nbsp;· the name, age, business address and residence address of the candidate;

&nbsp;&nbsp;&nbsp;&nbsp;· a resume describing the candidate's qualifications;

&nbsp;&nbsp;&nbsp;&nbsp;· other information about the candidate that would be required to be included in a proxy statement under the rules of the SEC;

The Nominating Committee may seek additional information regarding the candidate. The Nominating Committee will consider all potential candidates in the same manner regardless of the source of the recommendation.

In December 2022, in connection with the effectiveness of new SEC rules regarding universal proxy cards, or Universal Proxy Rules, and upon the recommendation of the Nominating Committee, the Board approved the amendment and restatement of the Company's Amended and Restated Bylaws to (i) align the advance notice provisions related to the nomination of director candidates by shareholders with the substantive requirements of the Universal Proxy Rules, and (ii) require that candidates for nomination and nominating persons (as defined in the Amended and Restated Bylaws) provide to the Company certain agreements and undertakings. As a condition to the use of the Universal Proxy Rules, a nominating person and each candidate for nomination must satisfy all of the applicable requirements in the Amended and Restated Bylaws with respect to such director nomination.

DELIVERING PROXY MATERIALS THROUGH ELECTRONIC MEANS

Important Notice Regarding the Availability of Proxy Materials for the Shareholder Meeting to Be Held on May 10, 2023

**The Notice of 2023 Annual Meeting of Shareholders, 2023 Proxy Statement and 2022 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 2022 Annual Report by providing access to the documents on the Internet instead of mailing printed copies. Accordingly, certain shareholders have received a "Notice of Availability" instead of printed copies of the proxy materials. The Notice of Availability instructs a shareholder on how to access and review all of the proxy materials on the Internet. The Notice of Availability also has instructions on how a shareholder may vote their shares. Although the Notice of Availability identifies the items to be voted on at the meeting, you cannot vote your shares merely by marking the Notice of Availability and returning it.

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.

If you previously requested a paper copy of the proxy materials (and you have not revoked that request) or if delivery of printed proxy materials is required by law, you will receive a copy of the proxy materials instead of the Notice of Availability.

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 electronically will save us the cost of producing and mailing documents to you and will help us conserve natural resources. Requests for electronic delivery may be made at *enroll.icsdelivery.com/awk*.

##### [**Table of Contents**](#toc)
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:

&nbsp;&nbsp;&nbsp;&nbsp;· if you are the registered holder of your shares, please contact American Stock Transfer & Trust Company, LLC, our transfer agent, as noted below in "—Contacting Us or Our Transfer Agent" or

&nbsp;&nbsp;&nbsp;&nbsp;· 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.

In some cases, these forward-looking statements can be identified by words with prospective meanings such as "intend," "plan," "estimate," "believe," "anticipate," "expect," "predict," "project," "propose," "assume," "forecast," "likely," "uncertain," "outlook," "future," "pending," "goal," "objective," "potential," "continue," "seek to," "may," "can," "should," "will" and "could" or the negative of such terms or other variations or similar expressions. Forward-looking statements are predictions based on the Company's current expectations and assumptions regarding future events. They are not guarantees or assurances of any outcomes, financial results, levels of activity, performance or achievements, and readers are cautioned not to place undue reliance upon them. These forward-looking statements are qualified by, and should be read together with, the risks and uncertainties and other risk factors set forth in the

2022 Form 10-K and the Company's other filings made under the Securities Act and the Exchange Act, and readers should refer to such risks, uncertainties and risk factors in evaluating such forward-looking statements.

##### [**Table of Contents**](#toc)
C. Other Information Regarding Adjusted O&M Efficiency Ratio.

Our adjusted O&M efficiency ratio is defined as our O&M expenses from our regulated businesses, divided by the operating revenues from our regulated businesses, where both O&M expenses and operating revenues were adjusted to eliminate purchased water expense. Operating revenues were further adjusted to exclude reductions for the amortization of excess accumulated deferred income taxes ("EADIT"). Additionally, from operation and maintenance expenses, we excluded the allocable portion of non-O&M support services costs, mainly depreciation and general taxes, that are reflected in our regulated businesses segment as O&M expenses, but for consolidated financial reporting purposes, are categorized within other line items in the Consolidated Statements of Operations. We excluded the items discussed above from the calculation as we believe such items are not reflective of management's ability to increase the efficiency of our regulated businesses.

We evaluate our operating performance using this ratio and we believe it is useful to investors because it directly measures improvement in the operating performance and efficiency of our regulated businesses. This information is derived from our consolidated financial information but is not presented in our financial statements prepared in accordance with GAAP. The information supplements and should be read in conjunction with our GAAP disclosures, and should be considered in addition to, and not a substitute for, any GAAP measure. Our adjusted regulated O&M efficiency ratio (i) is not an accounting measure that is based on GAAP; (ii) is not based on a standard, objective industry definition or method of calculation; (iii) may not be comparable to other companies' operating measures; and (iv) should not be used in place of the GAAP information provided elsewhere in this proxy statement and the 2022 Form 10-K. Accordingly, this may have significant limitations on its use.
