Global Water Resources, Inc.

Under Securities Exchange Commission (“SEC”) rules, we are providing our stockholders with access to our proxy materials, including this proxy statement and our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, on the Internet in lieu of mailing printed copies. We believe that these rules allow us to provide our stockholders with the information they need, while lowering the costs of delivery and reducing the environmental impact of our Annual Meeting.

As a result, our stockholders will receive in the mail a “Notice of Internet Availability of Proxy Materials” (the “Notice”). The Notice is different than the Notice of Annual Meeting of Stockholders that accompanies this proxy statement. We will begin mailing the Notice to stockholders on April 4, 2025, and the proxy materials will be first made available on the Internet on April 4, 2025.

The Notice will contain instructions on how to access and review our proxy materials and vote online. The Notice will also contain instructions on how you can request a printed copy of our proxy materials, including a proxy card if you are a record holder or a voting instruction form if you are a beneficial owner. By following the instructions in the Notice, you may request to receive, at no cost, a printed or electronic copy of our proxy materials for the Annual Meeting and indicate such delivery preference for future proxy solicitations. If you make such request by email and would like this delivery method for future proxy solicitations, you must specifically state in your email that such delivery preference should remain in effect for future proxy solicitations. Your request to receive future materials in paper or via email will remain in effect for future proxy solicitations until you terminate it. The proxy materials are available, free of charge, on our corporate website (www.gwresources.com) under “Investors” as well. By referring to our website, we do not incorporate the website or any portion of the website by reference into this proxy statement.

We also follow a procedure called “householding,” which the SEC has approved. Under this procedure, we may deliver a single copy of the Notice or proxy materials to stockholders who share the same address unless we have received contrary instructions from one or more of the stockholders. This procedure reduces our printing costs, mailing costs, and fees. All stockholders have the ability to access the proxy materials on the website referred to in the Notice. If you would like to receive a separate copy of the Notice or proxy materials, or a separate copy of future notices regarding the availability of proxy materials or future proxy materials (or, if you requested a printed copy of the proxy materials, an additional printed copy of the proxy materials), please submit your request to our mailing address: Global Water Resources, Inc., Attention: Corporate Secretary, 21410 North 19th Avenue, Suite 220, Phoenix, Arizona 85027, email:corporatesecretary@gwresources.com, or telephone number: 480-360-7775, and we will promptly deliver separate copies to you. Similarly, if you share an address with another stockholder and received multiple copies of the Notice or the proxy materials, you may write or call us at the above address and telephone number to make arrangements to receive a single copy of the Notice or the proxy materials at the shared address in the future.

If your shares are registered differently or are held in more than one account at a brokerage firm, bank, broker-dealer, or other similar organization, you may receive more than one Notice or more than one paper copy of the proxy materials. Please follow the instructions printed on each Notice that you receive and vote the shares represented by each Notice to ensure that all of your shares are voted. If you requested to receive a printed copy of the proxy materials, please follow the voting instructions on the proxy cards or voting instruction forms, as applicable, and vote all proxy cards or voting instruction forms, as applicable, to ensure that all of your shares are voted. We encourage you to have all accounts registered in the same name and address whenever possible.
