Offer Letter for Employment, dated August 1, 2024, between American Water Works Company, Inc. and David M. Bowler

This Confidentiality Policy and Agreement (“Confidentiality Agreement”) set forth your understanding and agreement with the provisions below which discuss the Company’s confidential and propriety information and trade secrets. You acknowledge and agree that you are signing this Confidentiality Agreement for good and adequate consideration including your employment by or continuing employment by American Water or one of its subsidiaries (collectively, the “Company”); the access that the Company is providing you to certain confidential and proprietary information and trade secrets described below; and the Company’s willingness to provide you with valuable opportunities, consideration and/or benefits. You further acknowledge that this Confidentially Agreement is in addition to existing American Water policies addressing the handling of sensitive information, cyber and information security.

The Company’s Confidentiality Policy

The protection of confidential business information and trade secrets is vital to the interests and the success of the Company. In the course of employment with the Company, employees may create, discover or receive proprietary and/or confidential information including, without limitation: all information about markets, key personnel, operational methods, proprietary intellectual property, real property, plans for future developments, projects in the pipeline, bid information, manuals, books, training materials, forms and procedures, policies, customer or prospective customer lists, customer-related data, marketing plans and strategies, financial information, technical information, technical processes and methods, algorithms, documents relating to any of the foregoing, and other written and oral materials (whether electronic or on hard copy) which are related to the business of the Company (collectively, “Confidential Information”). Confidential Information includes all forms and types of financial, business, scientific, technical, economic, or engineering information, including patterns, plans, compilations, program devices, formulas, designs, prototypes, methods, techniques, processes, procedures, programs, or codes, whether tangible or intangible, and whether or how stored, compiled, or memorialized physically, electronically, graphically, photographically, or in writing if -- (A) the Company has taken reasonable measures to keep such information secret; and (B) the information derives independent economic value, actual or potential, from not being generally known to, and not being readily ascertainable through proper means by, another person who can obtain economic value from the disclosure or use of the information. Confidential Information may also be “material, non-public information” as defined by federal securities laws and Company policy, both of which prohibit insider trading. Confidential Information may be contained in Company documents, computer programs, databases, investor documents, trading strategies and analytic models. Confidential Information is related to a product or service used, or intended for use, in interstate or foreign commerce.

Confidential Information must be protected as confidential and not copied, disclosed or used, directly or indirectly, at any time, other than for the Company’s benefit (to the extent permitted by law), unless and until such knowledge or information is in the public domain through no wrongful act by the employee(s). Employees must not, directly or indirectly, divulge or disclose to anyone (other than the Company or any of its affiliates or any person employed or designated by such entities who need to know), publish or make use of any Confidential Information without the Company’s express prior written consent; provided, however, that nothing shall prohibit or restrict an employee from participating, cooperating, or testifying in any action, investigation, or proceeding with, or providing information to, any governmental agency or legislative body, or any self-regulatory organization (collectively, the “Regulators”). Employees may engage in such activities with the Regulators without notifying or obtaining prior authorization from the Company.

Nothing in this document is intended to interfere with or discourage a good faith disclosure to any governmental entity related to a suspected violation of the law. The employee cannot and will not be held criminally or civilly liable under any federal or state trade secret law for disclosing otherwise protected trade secrets or confidential or proprietary information as long as the disclosure is made in (i) confidence to a federal, state, or local government official, directly or indirectly, or to an attorney and solely for the purpose of reporting or investigating a suspected violation of law; or (ii) a complaint or other document filed in a lawsuit or other proceeding, as long as such filing is made under seal. The Company will not retaliate against any employee in any way for a disclosure made in accordance with the law. In the event that the employee makes a disclosure, and the employee files a lawsuit against the Company alleging that the Company retaliated against the employee because of his or her disclosure, the employee may disclose the relevant trade secret or Confidential Information to his or her attorney and may use the trade secret or Confidential Information in the court proceeding only if (i) the employee ensures that any court filing that includes the trade secret or

Confidential Information at issue is made under seal; and (ii) the employee does not otherwise disclose the trade secret or Confidential Information except as required by court order.

Following the cessation of employment, employees shall deliver to the Company all documents or other materials in their possession, including all copies thereof, which contain or are derived from Confidential Information, and they shall not misappropriate, utilize, disclose or infringe upon the Confidential Information of the Company or any of its affiliates (including the recreation or reconstruction of Confidential Information from memory). At the Company’s request, employees must delete or destroy any and all files and/or backup files on any personal computer, telephone or storage device used for Company purposes, and, at the Company’s request, deliver and/or provide access to the Company to any such devices, cloud systems, disk, thumb and/or flash drives for the Company’s review and permit the Company to delete all Confidential or other Company proprietary material contained on such devices. Employees shall not analyze, reverse engineer, or otherwise seek to determine the composition or structure of any sample or device provided by the Company or the method by which such sample or device was created, except as specifically authorized by the Company in writing. All samples and devices, whether in whole or in pieces, shall be returned to the Company at its request.

A breach of this Agreement would cause irreparable harm and significant injury to the Company, the quantification of which is difficult to ascertain. Because such harm and injury could not be compensable by damages alone, the employee agrees that the Company shall have the right to enforce this Agreement by injunction (without the necessity of a bond or other security and without proving actual damages), specific performance, or other equitable relief without prejudice to any other rights and remedies available to the Company in the event of a breach of this Agreement. The employee acknowledges that: (i) an immediate and irreparable injury would occur without a seizure order; (ii) seizure of the Confidential Information would not interrupt the legitimate business operations of the employee; and (iii) an injunction would not prevent the employee from entering into an employment relationship. You further agree that the Company shall be entitled to its reasonable fees and costs if a court of competent jurisdiction issues a preliminary or permanent injunction against you or a court of competent jurisdiction finds that you breached the terms of the Agreement.

The Defend Trade Secrets Act of 2016 (“DTSA”) governs the trade secret aspects of this Agreement. Otherwise, the validity, interpretation, and enforceability of this Agreement shall be governed by the laws of the State of New Jersey and the United States of America without regard to the conflict of laws principles thereof. Employees with questions regarding this Confidentiality Agreement or the Company’s Confidentiality Policy including questions regarding whether any particular information constitutes “Confidential Information,” the public disclosure of which is prohibited hereunder, should contact their supervisor or the Chief Compliance Officer. Employees who improperly use or disclose trade secrets or Confidential Information may be subject to disciplinary action, up to and including termination of employment, as well as legal action, even if the employee does not actually benefit from the disclosed information.

You acknowledge that you (a) have carefully read and considered the provisions of this Confidentiality Agreement and the Company’s Confidentiality Policy (b) have had a reasonable opportunity to consult with an independent legal counsel of your choosing, and (c) accept this Confidentiality Agreement on the terms set forth herein, intending to be legally bound. You understand that it is your responsibility to read and comply with its contents and any revisions made to it.

You agree to waive and never to assert any such “moral” rights in AWIP Inventions during or after the cessation of your employment with by the Company.
