Acquisition of Water Systems from City of Tucson

On July 8, 2025, the Company’s GW-Ocotillo subsidiary completed the previously announced acquisition ofseven water systems from Tucson Water, the City of Tucson’s water utility, in an all-cash transaction for an amended purchase price of approximately $8.1 million. The systems served approximately 2,200 water service connections in Pima County with a rate base of approximately $7.7 million at the time of acquisition.

The acquisition, which served to grow our footprint in Pima County, was accounted for as a business combination under ASC Topic 805, Business Combinations and the purchase price was allocated to the acquired utility assets and liabilities based on the acquisition-date fair values. Fair values are determined in accordance with ASC Topic 820, Fair Value Measurement, which allows for the characteristics of the acquired assets and liabilities to be considered, particularly restrictions on the use of the asset and liabilities. Regulation is considered both a restriction on the use of the assets and liabilities, as it relates to inclusion in rate base, and a fundamental input to measuring the fair value in a business combination. Substantially all the Company’s operations are subject to the rate-setting authority of the ACC and are accounted for pursuant to accounting guidance for regulated operations. The rate-setting and cost recovery provisions currently in place for the Company’s regulated operations provide revenues derived from costs, including a return on investment of assets and liabilities included in rate base. As such, the fair value of the acquired utility assets and liabilities subject to these rate-setting provisions approximates the pre-acquisition carrying values and does not reflect any net valuation adjustments.

The purchase price allocation of the net assets acquired in the transaction is as follows as of the acquisition date:

The goodwill reflects the value paid primarily for the long-term potential for connection growth as a result of the Company’s increased scale and diversity, opportunities for synergies, and an improved risk profile.
