1 SETTLEMENT AGREEMENT DOCKET NOS. W-20446A-25-0022; SW- 20445A-25-0023 The purpose of this Settlement Agreement (“Agreement”) is to resolve all issues related to the general rate case applications filed in Docket Nos. W-20446A-25-0022 and SW-20445A-25-0023. This Agreement is entered into by the following entities: Global Water-Santa Cruz Water Company, Inc. (“GW-Santa Cruz”) Global Water-Palo Verde Utilities Company, Inc. (“GW-Palo Verde”) Residential Utility Consumer Office (“RUCO”) and Arizona Corporation Commission Utilities Division (“Staff”) These entities shall be referred to collectively as “Signatories;” a single entity shall be referred to individually as a “Signatory.” I. RECITALS I.1 On March 5, 2025, GW-Santa Cruz filed a general rate case application in Docket No. W-20446A-25-0022 (“GW-Santa Cruz Docket”). On that same date, GW-Palo Verde filed a general rate application in Docket No. SW-20445A-25-0023 (“GW-Palo Verde Docket”). Staff found both applications sufficient on April 4, 2025. On April 7, 2025, GW-Santa Cruz and GW-Palo Verde (collectively, “the Companies”) each filed a Motion to Consolidate in their respective dockets. That same date, RUCO filed a Motion to Intervene in both dockets. On April 22, 2025, Administrative Law Judge Christopher A. Nichols (“ALJ Nichols”) granted the Motions to Consolidate the GW-Santa Cruz Docket with the GW-Palo Verde Docket and granted RUCO’s Motion to Intervene. Hearing was scheduled to begin December 15, 2025. I.2 Staff and RUCO filed their Direct Testimony on or about October 1, 2025, and rate design testimony on October 14, 2025. On October 16, 2025, the Companies filed a Notice of Settlement Meeting in preparation of conducting settlement discussions on October 23, 2025. Although the settlement discussions took place on October 23, 2025, no settlement was reached at that time. On November 6, 2025, the Companies filed Rebuttal Testimony. On December 1, 2025, Staff and RUCO filed Surrebuttal

2 Testimony. On December 11, 2025, the Companies filed Rejoinder Testimony. I.3 On December 12, 2025, Staff and the Companies filed a Joint Motion for Amendment of the Procedural Schedule and Continuance of Hearing (“Motion to Continue”). On December 15, 2025, prior to public comment, ALJ Nichols granted the Motion to Continue. On January 14, 2026, ALJ Nichols issued a Procedural Order rescheduling the hearing to commence on August 3, 2026, the filing of supplemental surrebuttal testimony by Staff and RUCO on April 15, 2026, and the filing of supplemental rejoinder testimony by the Companies on May 15, 2026. I.4 On March 25, 2026, the Companies filed a Notice of Settlement Meeting. Settlement discussions took place on April 1, 2026. The settlement discussions were open, transparent, and inclusive of all Parties to this Docket who desired to participate. The Signatories filed a Notice of Settlement and Request to Modify Procedural Schedule regarding this matter on April 14, 2026. I.5 The terms of this Agreement are just, reasonable, fair, and in the public interest in that they, among other things, establish just and reasonable rates in compliance with the Arizona Constitution for the Companies customers; promote the convenience, comfort and safety, and the preservation of health, of the employees and patrons of the Companies; resolve the issues arising from Docket Nos. W-20446A-25-0022 and SW-20445A-25-0023; and avoid unnecessary litigation expense and delay. I.6 The Signatories agree to the bifurcation of the two Dockets whereby the signatories agree to the Terms and Conditions below for GW-Santa Cruz. In addition, the Signatories agree to the withdrawal of the Rate Application of GW-Palo Verde, with the agreement that GW-Palo Verde will refile its rate application in 2027 using a 2026 Test Year. (“2027 GW-Palo Verde Rate Case”) I.7 In consideration of the bifurcation and withdrawal of the GW-Palo Verde Docket, GW-Palo Verde agrees to seek an amendment to Decision No. 79424 (July 18, 2024), which set a temporary bill credit related to premature revenue collection of $1.73 per month for the average residential wastewater 3/4-inch customer to $2.85 per month. The increase to the temporary bill credit will coincide with new rates going into effect in the GW-Santa Cruz Docket. Final resolution of the bill credit and

3 premature revenue collection will be addressed in the 2027 GW-Palo Verde Rate Case. I.8 The Signatories agree to ask the Commission, with respect to the terms each agreed upon herein: (1) to find that the terms and conditions of this Agreement are just and reasonable and in the public interest, along with any and all other necessary findings, and (2) to approve the Agreement such that it and the rates contained herein may become effective on or about November 1, 2026. I.9 These recitals and the Exhibits to this Agreement are part of this Agreement and incorporated herein by reference as if fully set forth. I.10 The Signatories are aware there is or may be other Commission litigation relating to the Companies, separate and apart from the current GW-Santa Cruz Docket and GW-Palo Verde Docket (25-0022/25-0023). Nothing in this Agreement is meant to take any position regarding that litigation. This Agreement shall not be construed as resolving or attempting to resolve any contested issue other than those presented herein. TERMS AND CONDITIONS II. REVENUE REQUIREMENT II.1 Signatories agree that GW-Santa Cruz’s revenue requirement is $24,480,144, which is an increase of $2,254,822 over test-year revenues. Schedules setting forth the calculation of the revenue requirement, including agreed upon adjustments, are attached as Exhibit 1, Settlement Schedule A-1 to the Agreement. II.2 The proposed revenue requirement has been determined through a series of adjustments to GW-Santa Cruz’s initial proposed revenue requirement. These adjustments are reflected in the Settlement schedules. II.3 The revenue requirement reflects the following elements (Exhibit 1, Settlement Schedule D-1): II.3.1 A capital structure of 55% common equity and 45% debt. II.3.2 A Return on Equity of 9.6%. II.3.3 A 4.92% cost of long-term debt. II.3.4 A weighted average cost of capital of 7.49%.

4 II.3.5 No Fair Value Increment is included in this Agreement. II.4 The provisions set forth herein regarding the quantification of a capital structure, return on equity, cost of long-term debt, cost of capital, and the revenue requirement are made for purposes of settlement only and should not be construed as admissions against interest or waivers of litigation positions related to other or future cases. III. TEST YEAR EXPENSE III.1 Signatories agree that GW-Santa Cruz’s settlement adjusted test year expenses were $19,118,869. Test year expense is shown on Exhibit 1, Settlement Schedule C-1. The Signatories determined the proposed expenses in this rate case by agreeing to the adjustments identified in Exhibit 1 in order to resolve issues in dispute. IV. RATE BASE IV.1 The Signatories agree that GW-Santa Cruz’ rate base is $63,613,187 as set forth in Exhibit 1, Settlement Schedule B-1. The Signatories determined the proposed FVRB in this rate case by agreeing to certain adjustments reflected in Exhibit 1, in order to resolve issues in dispute. Included in the changes to rate base identified in the schedules, is the following: IV.1.1 Plant Held For Future Use (Terrazo WDC) – Signatories agree that GW-Santa Cruz may seek recovery of, and on, the PHFFU in the amount of $3,383,385 in the next rate case. V. AFUDC V.1 The Signatories agree, on a going forward basis, GW-Santa Cruz shall not compound interest when calculating AFUDC. Exhibit 2 is an illustrative example of the methodology GW-Santa Cruz will use to calculate AFUDC on a going-forward basis. VI. DEPRECIATION RATES VI.1 The depreciation rates for GW-Santa Cruz are set forth in Exhibit 3. VII. RATE DESIGN AND BILL IMPACTS VII.1 The rate tariff based on the revenue requirement is set forth in Exhibit 4 to the Agreement.

5 VII.2 The current bill for the median customer with a 3/4-inch meter using approximately 5,500 gallons of water is $35.73, with this settlement resulting in an increase of $2.68, for a proposed bill of $38.41, or an overall increase of 7.50%. Representative bill impacts for the other meter sizes resulting from the new rates are set forth in Exhibit 1, Settlement Schedule H-4, pages 1-22. VIII. SUSTAINABLE WATER SURCHARGE MECHANISM VIII.1 GW-Santa Cruz’ proposed Sustainable Water Surcharge (“SWS”) mechanism shall incorporate RUCO’s proposed modifications adopted consistent with the Plan of Administration (“SWS POA”) and provided as Attachment Piro Rebuttal-2. The proposed SWS POA is set forth in Exhibit 6. IX. TARIFF APPROVALS AND ADDITIONAL ADJUSTOR MECHANISMS IX.1 Terms and Conditions Tariff GW-Santa Cruz will continue to utilize the existing Terms and Conditions Tariff approved in Decision No. 79383. IX.2 Curtailment Tariff GW-Santa Cruz will continue to utilize the existing Curtailment Tariff approved in Decision No. 79383. IX.3 Customer Assistance Tariff GW-Santa Cruz will continue to utilize the existing Customer Assistance Tariff approved in Decision No. 79383 but break out GW-Santa Cruz separately as a stand-alone charge for utility tracking and funding purposes.

IX.5 Hydrant Meter Deposit Charge Tariff GW-Santa Cruz will continue to utilize the existing Hydrant Meter Deposit Charge Tariff approved in Decision No. 79383.

6 IX.6 Meter Downsizing Tariff GW-Santa Cruz will continue to utilize the existing Meter Downsizing Tariff approved in Decision No. 79383. IX.7 Tax Expense Adjustor Mechanism GW-Santa Cruz will continue to utilize the existing Tax Expense Adjustor Mechanism (“TEAM”) approved in Decision No. 78644. IX.8 Best Management Practices Tariff GW-Santa Cruz will continue to utilize the existing Best Management Practices Tariffs approved in Decision No. 78644. IX.9 Off-site Hook-up Fee Tariff GW-Santa Cruz will continue to utilize the existing Off-site Hook-fee tariff approved by operation of law in Docket No. W-20446A-19-0178. IX.10 Point of Use Treatment Device Tariff GW-Santa Cruz will continue to utilize the existing Point of Use Treatment Device tariff approved by operation of law in Docket Nos. W-02450A-23-0237. et al. X. RATE CASE EXPENSE SURCHARGE X.1 The Signatories agree to a rate case expense surcharge for GW-Santa Cruz, to recover an amount not to exceed $250,000, recoverable through a monthly surcharge assessed over three years with a maximum monthly rate case expense surcharge of $0.35 per customer. The surcharge shall terminate automatically if the expenses are recovered in full before the three-year period expires. X.2 The Signatories agree that GW-Palo Verde shall defer and record all actual rate case expenses incurred in the GW-Palo Verde Docket (SW- 20445A- 25-0023) as a deferred debit in NARUC Account No. 186.1, Deferred Rate Case Expense. GW-Palo Verde agrees that it shall not seek a return on the deferred debit. Such amounts may be presented for recovery as expenses in its next general rate case filing, anticipated in 2027, and, all parties agree that no expenses are pre-approved, and if approved in the next general rate case, amortized over a period determined by the Commission.

7 XI. COMPLIANCE MATTERS XI.1 The Signatories agree that the compliance item in Decision No. 67830/771211 (May 5, 2004) (filing annual reports on the compliance status of Santa Cruz Water Company, LLC, with Arizona Department of Environmental Quality, Arizona Department of Water Resources, and Arizona Corporation Commission) be removed. XI.2 The Signatories agree that the compliance item in Decision No. 74364 (February 26, 2014) (CEO Affidavit that GW-entities are compliant with the terms of the Settlement Agreement in that case) be removed. XII. FILING REQUIREMENTS XII.1 The Signatories agree to the withdrawal of the Rate Application of GW-Palo Verde, with the agreement that GW-Palo Verde will refile a 2027 GW-Palo Verde Rate Case. If requested by GW-Palo Verde, the Signatories agree to make a good faith effort to request a condensed schedule (faster than the typical Class A time clock) for the 2027 Rate Case. XII.2 GW-Palo Verde’s motion to withdraw the Rate Application shall include a request that the Settlement Agreement is binding upon GW-Palo Verde before the withdrawal is granted, but it may be done in the same Commission order. XII.3 In consideration for the Settlement Agreement, GW-Palo Verde agrees that it will not seek formula rates in the 2027 GW-Palo Verde Rate Case. XII.4 GW-Santa Cruz agrees not to file another Rate Application until after January 1, 2028. XII.5 For the 2027 GW-Palo Verde Rate Case, GW-Palo Verde agrees that it will meet with Staff, no later than 60 days prior to the filing, to identify data requests to be completed by its filing or shortly thereafter. XII.6 The Signatories agree that GW-Santa Cruz shall, in its next rate case, conduct a cost of service analysis consistent with R14-2-103(B) which provides analysis of the total revenue requirement allocated across customer classes (residential, commercial and industrial). 1 Decision No. 77121 (March 13, 2019) modified the quarterly requirement set in Decision No. 67830 to an annual requirement.

8 XIII. COMMISSION EVALUATION OF PROPOSED SETTLEMENT XIII.1 The application in the GW-Santa Cruz docket, all currently filed testimony, tariffs and exhibits, and this Agreement and its exhibits shall be admitted into the Commission’s record as evidence. XIII.2 The Signatories recognize that Staff does not have the power to bind the Commission. For purposes of proposing a settlement agreement, Staff acts in the same manner as any party to a Commission proceeding. XIII.3 This Agreement shall serve as a procedural device by which the Signatories will submit their proposed settlement of GW-Santa Cruz’s pending rate case, Docket No. W-20446A-25-0022, and the foregoing agreements relating to GW-Palo Verde’s currently pending rate case, Docket No. SW-20445A-25-0023, to the Commission. XIII.4 The Signatories recognize that the Commission will independently consider and evaluate the terms of this Agreement. If the Commission issues an order adopting all material terms of this Agreement, such action shall constitute Commission approval of the Agreement. Thereafter, the Signatories shall abide by the terms as approved by the Commission. For purposes of this Settlement Agreement, whether a term is material shall be left to the discretion of each Signatory. XIII.5 If the Commission fails to issue an order adopting all material terms of this Agreement, any or all of the Signatories may withdraw from this Agreement and seek a hearing, and such Signatory or Signatories may pursue without prejudice their respective remedies at law. For purposes of this Agreement, whether a term is material shall be left to the discretion of the Signatory choosing to withdraw from the Agreement. If a Signatory withdraws from the Agreement pursuant to this paragraph and files an application for rehearing, the other Signatories, except for Staff, shall support the application for rehearing by filing a document with the Commission that supports approval of the Agreement in its entirety. Staff shall not be obligated to file any document or take any position regarding the withdrawing Signatory’s application for rehearing. XIV. MISCELLANEOUS PROVISIONS XIV.1 The Signatories agree that all filed documents and Exhibits in the GW-Santa Cruz docket will be admitted into evidence without cross examination by any Signatory.

9 XIV.2 To achieve consensus for settlement, the Signatories are accepting positions that, in any other circumstances, they may be unwilling to accept. They are doing so because this Agreement and its terms, as to the terms to which each Signatory agrees, when taken as a whole are consistent with their long-term interests and with the broad public interest. The acceptance by any Signatory of a specific element of this Agreement shall not be considered as precedent for acceptance of that element in any other context. XIV.3 No Signatory is bound by any position asserted in negotiations, except as expressly stated in this Agreement. No Signatory shall offer evidence of conduct or statements made in the course of negotiating this Agreement before this Commission, any other regulatory agency, or any court. XIV.4 Neither this Agreement nor any of the positions taken in this Agreement by any of the Signatories may be referred to, cited, and/or relied upon as precedent in any proceeding before the Commission, any other regulatory agency, or any court for any purpose except to secure approval of this Agreement and enforce its terms. XIV.5 To the extent any provision of this Agreement is inconsistent with any existing Commission order, rule, or regulation, this Agreement shall control. XIV.6 Each of the terms of this Agreement is in consideration of all other terms of this Agreement. Accordingly, the terms are not severable. XIV.7 The Signatories shall make reasonable and good faith efforts necessary to obtain a Commission order approving this Agreement. The Signatories shall support and defend this Agreement before the Commission. Subject to Paragraphs XIII.4 and XIV.6 above, if the Commission adopts an order approving all material terms of the Agreement, the Signatories will support and defend the Commission’s order before any court or regulatory agency in which it may be at issue. XIV.8 This Agreement may be executed in any number of counterparts and by each Signatory on separate counterparts, each of which when so executed and delivered shall be deemed an original and all of which taken together shall constitute one and the same instrument. This Agreement may also be executed electronically or by facsimile.

EXHIBIT 5 Sustainable Water Surcharge Plan of Administration (Redline Version)

Global Water – Santa Cruz Water Company, Inc. Effective Date: Decision No: Docket No: W-20446A-25-0022 1 Sustainable Water Surcharge Plan of Administration APPLICABLE TO:  Global Water – Santa Cruz Water Company, Inc. (“GW-Santa Cruz” or the “Company”)  Global Water – Belmont Water Company, Inc. (“GW-Belmont”)  Global Water – Turner Ranches Irrigation, Inc. (“GW-Turner”)  Global Water – Saguaro District Company, Inc. (“GW-Saguaro”)  Global Water – Farmers Water Company, Inc. (“GW-Farmers”) 1) INTRODUCTION. This document is the Plan of Administration (“POA”) for the Sustainable Water Surcharge (“SWS”) for GW-Santa Cruz. The SWS allows the Company to pass through to its customers the costs related to the purchase and exchange of sustainable water supplies as well as the recovery of capital and ongoing operations and maintenance of acquiring new water supplies and resources in- between rate cases.1 2) GENERAL DESCRIPTION OF SWS. A) The purpose of the SWS is to recover the costs of purchasing sustainable water supplies, utilizing those sustainable water supplies via exchange, wheeling, or storage and recovery. Recoverable costs include contracting, delivery, legal, and administrative costs paid to 1 This Plan of Administration shall not apply to any new water supply relating to the Barlett Dam. Any determination about whether expenses relating to the Bartlett Dam project shall be determined in a separate docket consistent with the AWC Decision No. 81022 at pages 97, 128-129.

Global Water – Santa Cruz Water Company, Inc. Effective Date: Decision No: Docket No: W-20446A-25-0022 2 Central Arizona Project (“CAP”) and others as necessary to allow the Company to deliver the renewable water supplies to the Company’s customers via exchange, wheeling, or storage and recovery and thereby reduce the Company’s pumping of groundwater in its service areas creating a more resilient and sustainable water future for its customers. For the purposes of this POA, “wheeling” or to “wheel” means to transport water using third party infrastructure, such as a canal or pipeline. Recoverable costs will also include costs associated with maintaining a Member Service Agreement (“MSA”) with the Central Arizona Water Conservation District (“CAWCD”), including annual membership dues and replenishment fees and the reduction of these fees when sustainable water is put to use. The SWS will include costs for groundwater withdrawal fees paid to the Arizona Department of Water Resources (“ADWR”) since these costs may be reduced as the Company increases its use of sustainable water supplies and reduces its use of groundwater. Additionally, the SWS mechanism will recover the capital investments and on-going operations and maintenance costs of acquiring new water supplies or resources for longer-term projects when the opportunities arise.2 Given the need for additional water supplies and the unpredictable and capital intensive nature of the water supply market, this mechanism will also allow the Company the ability to fund critical water supply investments when opportunities arise. Once a water supply is acquired, the appropriate cost components can be characterized as Category 2 Please see “Category 3” costs for a detailed explanation of the capital and on-going O&M costs.

Global Water – Santa Cruz Water Company, Inc. Effective Date: Decision No: Docket No: W-20446A-25-0022 3 3 Costs outlined below. In addition to the regular filings outlined below, the Category 3 Cost Component will be integrated into a supply-specific surcharge to be set semi-annually. This will be in addition to the current Category 1 and Category 2 SWS cost components which are calculated biannually. The qualifying cost components will be aggregated as a SWS rate and will continue to be billed to the appropriate customers on a per thousand gallons basis for the Category 1 and 2 costs. The Category 3 costs will be by means of a monthly fixed rate and a commodity rate billed on a per thousand gallons basis. The recovery will be split evenly between the fixed and commodity rate components and are described in detail below. B) The SWS is applicable to all water sales by the Company, including residential, commercial, construction, and potable sales. C) The Company will make semi-annual SWS filings (the first being due January 31, 2023, then by January 31 and July 31 of each year thereafter) to adjust the SWS rate. Included with the January 31 and July 31 filing, the Company will include the Category 3 costs surcharge calculation. The Company’s SWS rate will be billed per thousand gallons sold for all water customers. The SWS will appear on customers’ bills as a separate line item labeled "Sustainable Water Surcharge". The rate for the costs will be adjusted semi-annually, March 1 and September 1 of each year to true up the previous six months (“True-Up Period”) of activity and recover actual costs incurred in the most recent six months (“Recent Cost Recovery Period”). The chart below delineates examples of filings and timeframes. Within 30 days of each semiannual recovery filing, the Commission’s Utilities Division shall docket

Effective Date: Decision No: Docket No: W-20446A-25-0022 4 a Staff Memorandum and Proposed Order for approval, modification, or rejection of the surcharge adjustment. The surcharge adjustment shall not take effect until approved by the Commission. 3) COMPONENTS OF SWS. The SWS is implemented via a semi-annual reconciliation3 which includes: 1) True-Up Period Under/Over Recovery, 2) Recent Cost Recovery Period Recovery, and 3) Determination of the Surcharge Rate, Per 1,000 Gallons of Usage. A) True-Up Period Under/Over Recovery4 This component accounts for the under- or over- recovery of the Company’s prior period’s sustainable water costs through the surcharge. The computation is: a) The Company’s actual sustainable water costs for the previous six month True- Up Period ending either June 30, or December 31. b) Less actual annual SWS revenues collected by the Company through the end of the previous six-month True-Up Period year ending either June 30, or December 31. c) Equals the Over / Under Collection Balance. 3 Category 3 costs will be reconciled semi-annually. Filing Due Date Rate Effective Date Recent Cost Recovery Period True-Up Period 1/31/2023 3/1/2023 July 2022 – December 2022 January 2022–June 2022 7/31/2023 9/1/2023 January 2023 – June 2023 July 2022–December 2022
