Item 8.01 Other Events.

As previously reported, on March 5, 2025, two of the regulated subsidiaries of Global Water Resources, Inc. (the “Company”), Global Water – Santa Cruz Water Company, Inc. (“GW-Santa Cruz”) and Global Water – Palo Verde Utilities Company, Inc. (“GW-Palo Verde” and collectively with GW-Santa Cruz, the “GW-Utilities”), each filed a rate case application and related schedules with the Arizona Corporation Commission (the “ACC”) for, among other things, increased rates. If approved by the ACC, the requested rate increases would result in a net annual revenue increase of approximately $6.5 million, an approximate 11% increase in the total median monthly aggregate bill for GW-Santa Cruz and GW-Palo Verde customers, and an adjusted rate base of approximately $164.6 million.

On October 1, 2025, the ACC Utilities Division (“ACC Staff”) and the Residential Utility Consumer Office, representing the interests of residential utility ratepayers (“RUCO”), filed their respective initial written testimonies with the ACC in the rate case. The filed ACC Staff and RUCO testimonies include recommendations that materially differ from the rate case applications filed by the GW-Utilities as described above. The ACC Staff recommended, among other things, a net annual revenue decrease of approximately $7.1 million and an adjusted rate base of approximately $78.7 million while RUCO recommended, among other things, a net annual revenue increase of approximately $3.0 million and an adjusted rate base of approximately $156.6 million. With respect to the ACC Staff written testimony, the ACC Staff indicated that its recommendation reflected certain adjustments for post-test year plant (“PTYP”) projected through August 1, 2025 and further recommended the Company send updated information relating to any PTYP projects completed through December 31, 2025 so that the ACC Staff can update its recommendation on PTYP adjustments in additional rounds of testimony. Following the filing of these initial written testimonies, the Company has had discussions with the ACC Staff regarding their initial recommendations (including most recently on October 14, 2025), where the parties agreed to begin settlement discussions as early as the week of October 20, 2025.

The GW-Utilities’ rebuttal testimony is due November 6, 2025, surrebuttal testimony from ACC Staff and RUCO is due December 1, 2025, and rejoinder testimony from the GW-Utilities is due December 10, 2025. The Company intends to use the rebuttal, surrebuttal, and rejoinder process to reconcile differences between the GW-Utilities’ rate case applications and the ACC Staff's and RUCO’s initial testimony. A hearing with the Administrative Law Judge (“ALJ”) is scheduled to begin December 15, 2025, after which the ALJ will issue a Recommended Opinion and Order (“ROO”) that the ACC will vote on at a later date. Both the ROO and the ACC vote are anticipated in the first half of 2026. Unfavorable ACC Staff and intervenor positions and recommendations, if ultimately adopted by the ACC, could have a material adverse impact on the Company’s financial condition, results of operations, and cash flows.

There can be no assurance that the Company will be successful in reconciling the differences between the GW-Utilities’ rate case applications and the ACC Staff's and RUCO’s initial testimony. Further, the Company cannot speculate as to the ACC’s final determination of the rate case applications in any respect whatsoever.

The rate case applications and initial testimonies are available on the ACC website at edocket.azcc.gov. The applications’ ACC docket numbers are 25-0022 and 25-0023. The information on this website is not incorporated by reference into this Current Report on Form 8-K.
