Regulatory Decision and Related Accounting and Policy Changes

REGULATORY DECISION AND RELATED ACCOUNTING AND POLICY CHANGES

The Company’s regulated utilities and certain other balances are subject to regulation by the ACC and meet the requirements for regulatory accounting found within Accounting Standards Codification (“ASC 980”), Regulated Operations.

In accordance with ASC 980, rates charged to utility customers are intended to recover the costs of the provision of service plus a reasonable return in the same period. Changes to the rates are made through formal rate applications with the ACC, which the Company has done for all of the operating utilities and which are described below.

On July 3, 2023, Global Water-Palo Verde Utilities Company, Inc. (“Palo Verde”) and Global Water-Santa Cruz Water Company, Inc. (“Santa Cruz”) filed an application with the ACC for approval of an accounting order to defer and record as a regulatory asset the depreciation expense recorded for the Company’s Southwest Plant, plus the carrying cost at the authorized rate of return set in Palo Verde’s and Santa Cruz’s most recent rate order, until the plant is considered for recovery in the utilities’ next rate case. The Southwest Plant was substantially constructed prior to 2009 to provide water, wastewater, and recycled water utility service for the area southwest of the City of Maricopa. Due to the unprecedented collapse of the housing market during the Great Recession, the nearly completed plant remained idle for well over a decade. The total cost of the Southwest Plant was approximately $38.4 million. In July 2023, $27.5 million related to the water production plant and a portion of the wastewater processing plant was placed in service, with the remaining parts of the Southwest Plant to be placed in service once sufficient flows, provided by connection growth, are established. There can be no assurance, however, that the ACC will approve the application as submitted and the ACC could take other actions regarding the application.

On June 27, 2023, seven of the Company’s 13 regulated utilities each filed a rate case application with the ACC for increased water rates based on a 2022 test year. In addition to a rate increase, the Company requested, among other things, the consolidation of water rates for certain of its utilities, including Global Water-Mirabell Water Company, Inc. (“Mirabell”), Global Water-Lyn Lee Water Company, Inc. (“Lyn Lee”), Global Water-Francesca Water Company, Inc. (“Francesca”), Global Water-Tortolita Water Company, Inc. (“Tortolita”), Global Water-Rincon Water Company, Inc. (“Rincon”), Global Water-Las Quintas Serenas Water Company, Inc. (“Las Quintas Serenas”), and Global Water-Red Rock Water Company, Inc. (“Red Rock”), each located in Pima County. Of the Company’s utilities, these utilities filing rate applications make up approximately 3% of the Company’s active service connections. There can be no assurance that the ACC will approve the requested rate increase or any increase or the consolidation of water rates described above, and the ACC could take other actions as a result of the rate case. Further, it is possible that the ACC may determine to decrease future rates. There can also be no assurance as to the timing of when an approved rate increase (if any) would go into effect.

On July 27, 2022, the ACC issued Rate Decision No. 78644 relating to the Company’s previous rate case. Pursuant to Rate Decision No. 78644, the ACC approved, among other things, a collective annual revenue requirement increase of approximately $2.2 million (including the acquisition premiums discussed below) based on 2019 test year service connections, and phased-in over approximately two years, as follows:

	Incremental		Cumulative
August 1, 2022	$	1,457,462	$	1,457,462
January 1, 2023	$	675,814	$	2,133,277
January 1, 2024	$	98,585	$	2,231,861

To the extent that the number of active service connections has increased and continues to increase from 2019 levels, the additional revenues may be greater than the amounts set forth above. On the other hand, if active connections decrease or the Company experiences declining usage per customer, the Company may not realize all of the anticipated revenues.

Rate Decision No. 78644 also addressed the primary impacts of the Federal Tax Cuts and Jobs Act (the “TCJA”) on the Company, which includes the reduction of the federal income tax rate from 35 percent to 21 percent beginning on January 1, 2018. The TCJA required the Company to re-measure all existing deferred income tax assets and liabilities to reflect the reduction in the federal tax rate. For the Company’s regulated entities, substantially all of the change in deferred income taxes is recorded as an offset to either a regulatory asset or liability because the impact of changes in the rates are expected to be recovered from or refunded to customers. Rate Decision No. 78644 approved an adjustor mechanism for income taxes (as described below) that permits the Company to flow through potential changes to state and federal income tax rates as well as refund or collect funds related to TCJA.

The ACC also approved:

(i) the consolidation of water and/or wastewater rates to create economies of scale that are beneficial to all customers when rates are consolidated;

(ii) acquisition premiums relating to the Company’s acquisitions of its Red Rock and Turner Ranches utilities, which increase the rate base for such utilities and result in an increase in the annual collective revenue requirement included in the table above;

(iii) the Company’s ability to annually adjust rates to flow through certain changes in tax expense, primarily related to income taxes, without the necessity of a rate case proceeding; and

(iv) a sustainable water surcharge, which will allow semiannual surcharges to be added to customer bills based on verified costs of new water resources.

Finally, Rate Decision No. 78644 required the Company to work with ACC staff and the Residential Utility Consumer Office to prepare a Private Letter Ruling request to the Internal Revenue Service (“IRS”) to clarify whether the failure to eliminate the deferred taxes attributable to assets condemned in a transaction governed by Section 1033 of the Internal Revenue Code (“IRC”) would violate the normalization provisions of Section 168(i)(9) of the IRC. The IRS accepted the request and issued its Private Letter Ruling, dated September 22, 2023. The Private Letter Ruling determined that the deferred taxes attributable to assets condemned in a transaction governed by Section 1033 of the IRC must be eliminated and failure to do so would violate the normalization provisions of Section 168(i)(9) of the IRC. As required by Rate Decision No. 78644, the Private Letter Ruling has been provided to the ACC. Within 90 days after receiving the ruling, ACC Staff is required to prepare, for ACC consideration, a memorandum and proposed order regarding guidance issued within the Private Letter Ruling. The Private Letter Ruling was consistent with the adjustments used to determine the revenue requirements in Rate Decision No. 78644. Accordingly, the Company has requested that no further action be taken by the ACC. However, there can be no assurance provided until the ACC process is complete.

Certain accounting implications related to Rate Decision No. 78644 were recognized and recorded as of June 30, 2022, and are as follows:

•Reclassification of Red Rock Water, Red Rock Wastewater, and Turner Ranches acquisition premiums of approximately $0.8 million in the aggregate from goodwill to regulatory assets to be included in rate base. The premiums are to be amortized over 25 years.

•Reversal of the 2017 TCJA tax reform regulatory liability of approximately $0.8 million, which was recorded as a reduction to income tax expense for approximately $0.7 million, and as a reduction to interest expense for approximately $0.1 million.

•Write-off of approximately $0.3 million in capitalized rate case costs.

Infrastructure Coordination and Financing Agreements

Infrastructure Coordination and Financing Agreements (“ICFAs”) are agreements with developers and homebuilders where the Company provides services to plan, coordinate, and finance the water and wastewater infrastructure that would otherwise be required to be performed or subcontracted by the developer or homebuilder. Rate Decision No. 74364, issued by the ACC in February 2014, established the policy for the treatment of ICFA funds and also prohibited the Company from entering into any new ICFAs. Rate Decision No. 74364 requires a hook-up fee (“HUF”) tariff to be established for all ICFAs that come due and are paid subsequent to December 31, 2013, which is a set amount per equivalent dwelling unit determined by the ACC based on the utility and meter size. In addition, since ICFA funds are generally received in installments, Rate Decision No. 74364 prescribes that 70% of funds received must be recorded as a HUF liability, with the remaining 30% to be recorded as deferred revenue, until the HUF liability is fully funded. The Company is responsible for assuring that the full HUF tariff, which is the set amount determined by the rate decision, is funded in the HUF liability, even if it results in recording less than 30% of the

overall ICFA funds as deferred revenue. Refer to Note 3 – “Revenue Recognition - Unregulated Revenue” for additional information.

The Company accounts for the portion allocated to the HUF as a contribution in aid of construction (“CIAC”). However, in accordance with the ACC directives, the CIAC is not deducted from rate base until the HUF funds are expended for utility plant. Such funds are segregated in a separate bank account and used for plant.

A HUF liability is established and amortized as a reduction of depreciation expense over the useful life of the related plant once the HUF funds are utilized for the construction of plant. For facilities required under a HUF or ICFA, the utilities must first use the HUF moneys received, after which, it may use debt or equity financing for the remainder of construction.

Regulatory Assets and Liabilities

Regulatory assets and liabilities are the result of operating in a regulated environment in which the ACC establish rates that are designed to permit the recovery of the cost of service and a return on investment. The Company capitalizes and records regulatory assets for costs that would otherwise be charged to expense if it is probable that the incurred costs will be recovered in future rates. Regulatory assets are amortized over the future periods that the costs are expected to be recovered. Final determination of whether a regulatory asset can be recovered is decided by the ACC in regulatory proceedings. If the Company determines that a portion of the regulatory assets is not recoverable in customer rates, the Company would be required to recognize the loss of the assets disallowed.

If costs expected to be incurred in the future are currently being recovered through rates, the Company records those expected future costs as regulatory liabilities.

The Company’s regulatory assets and liabilities consist of the following (in thousands):

	Recovery Period	September 30, 2023		December 31, 2022
Regulatory Assets
Income taxes recoverable through future rates (1)	Various	$	1,423	1,482
Rate case expense surcharge(2)	2 years	284		467
Acquisition premiums(3)	25 years	1,277		1,220
Total regulatory assets		$	2,984	$	3,169
Regulatory Liabilities
Income taxes payable through future rates(1)		493		508
Acquired ICFAs(4)		4,896		5,863
Depreciation adjustment(5)		705		—
Total regulatory liabilities		$	6,094	$	6,371

(1) The TCJA required the Company to re-measure all existing deferred income tax assets and liabilities to reflect the reduction in the federal tax rate. For the Company’s regulated entities, substantially all of the change in deferred income taxes is recorded as an offset to either a regulatory asset or liability because the impact of changes in the rates are expected to be recovered from or refunded to customers.

(2) Rate Decision No. 78743, issued on October 24, 2022, approved approximately $0.5 million in rate case expenses to be recovered through a rate case expense surcharge over a two-year period.

(3) Rate Decision No. 78319, issued on December 3, 2021, approved an acquisition premium to be amortized over 25 years related to the acquisition of the Company’s Rincon utility. Amortization will begin once the Company receives a decision on the recently filed rate case and the acquisition premium is approved to be included in customer rates. The acquisition premium balance as of September 30, 2023 was approximately $0.5 million.

Rate Decision No. 78644, issued on July 27, 2022, approved acquisition premiums related to the acquisitions of the Company’s Turner Ranches and Red Rock utilities. Amortization began in 2022 as the acquisition premiums were included in customer rates as approved in the decision. The acquisition premium balance as of September 30, 2023 was approximately $0.8 million.

(4) The acquired ICFA regulatory liability relates to the offset of intangible assets related to ICFA contracts obtained in connection with the Santa Cruz, Palo Verde, and Sonoran Utility Services, LLC (“Sonoran”) acquisitions. When ICFA funds

are received, a portion of the funds reduce the acquired ICFA liability as a partial offset to the amortization expense recognition of the related intangible asset.

(5) Rate Decision No. 78644 issued on July 27, 2022, approved an adjustment to update previously approved depreciation rates.
