Water sales are seasonal in nature and influenced by weather conditions. The timing of precipitation and climatic conditions can cause seasonal water consumption by customers to vary significantly. Due to the seasonal nature of the water business, the operating results for interim periods are not indicative of the operating results for a 12-month period. Revenue is generally higher in the warm, dry summer months when water usage and sales are greater, and lower in the winter months when cooler temperatures and increased precipitation curtail water usage resulting in lower sales.

The following instruments are not measured at fair value on H2O America’s condensed consolidated balance sheets as of June 30, 2026, but require disclosure of their fair values: cash and cash equivalents, accounts receivable and accounts payable. The estimated fair value of such instruments as of June 30, 2026 approximates their carrying value as reported on the condensed consolidated balance sheets. There have been no changes in valuation techniques during the three and six months ended June 30, 2026. The fair value of these instruments would be categorized as Level 2 in the fair value hierarchy, with the exception of cash and cash equivalents, which would be categorized as Level 1.

The fair value of H2O America’s long-term debt was $1,716.5 million and $1,716.6 million as of June 30, 2026 and December 31, 2025, respectively, and was determined using a discounted cash flow analysis, based on the current rates for similar financial instruments of the same duration and creditworthiness of the company. Of the total fair value of long-term debt at June 30, 2026 and December 31, 2025, $1,698.4 million and $1,715.6 million, respectively, would be categorized as Level 2 in the fair value hierarchy and $18.1 million and $1.0 million, respectively, would be categorized as Level 3 in the fair value hierarchy.

Basic earnings per share is calculated using income available to common stockholders, divided by the weighted average number of shares outstanding during the period. Diluted earnings per share is calculated using the treasury stock method which comprises income available to common stockholders divided by the weighted average number of shares of common stock including both shares outstanding and shares potentially issuable in connection with restricted common stock awards under H2O America’s long-term incentive plans, and shares potentially issuable under the equity forward purchase agreements granted to investors in the equity offering discussed further in Note 3 “Capitalization” to these condensed consolidated financial statements. For the three months ended June 30, 2026 and 2025, 1,886 and 8,900 anti-dilutive restricted common stock units were excluded from the diluted earnings per share calculation, respectively. For the six months ended June 30, 2026 and 2025, 2,848 and 23,346 anti-dilutive restricted common stock units were excluded from the diluted earnings per share calculation, respectively.

The recently issued accounting standards that have not yet been adopted by the company as of June 30, 2026 are as follows:

ASU 2024-03 “Disaggregation of Income Statement Expenses”

The ASU requires disclosure, in the notes to the financial statements, of specified information about certain costs and expenses. The ASU requires disclosure of purchases of inventory, employee compensation, depreciation, and intangible asset amortization in interim and annual reporting periods. Further, other amounts already required to be disclosed in accordance with current U.S. GAAP would be included in the same disclosure as the other disaggregation requirements. Additionally, the ASU requires qualitative descriptions of amounts remaining in relevant expense captions that are not separately disaggregated quantitatively as well as disclosure of selling expenses in annual periods and an entity’s definition of selling expenses.

The ASU is effective for H2O America for its annual financial statements for the year ending December 31, 2027 and for interim reporting periods for the year ending December 31, 2028. Early adoption is permitted.

Prospective, with retrospective application also permitted.

The standard is expected to only result in updates to disclosure and is not expected to have a material impact on the Company’s financial position and results of operations.

ASU 2025-06 “Intangibles-Goodwill and Other-Internal-Use Software (subtopic 350-40)”

The ASU updates the accounting for internal-use software by removing project stage references and introduces a new capitalization threshold based on management authorization and project completion probability. The guidance requires evaluation of significant development uncertainty, including novel functionality and unresolved performance requirements. ASU 2025-06 clarifies that capitalized internal-use software costs are subject to the property, plant and equipment disclosure requirements under ASC 360-10.

The ASU is effective for H2O America for its annual financial statements for the year ending December 31, 2028 and for interim reporting periods for the year ending December 31, 2028.

Prospective, with retrospective application also permitted.

H2O America is currently evaluating the impact of ASU 2025-06 on its financial statements and will adopt ASU 2025-06 in fiscal year ended December 31, 2028.

ASU 2025-10 “Government Grants (Topic 832)”

The ASU establishes accounting for government grants received by business entities and includes guidance for (1) a grant related to an asset and (2) a grant related to income. The ASU requires that a government grant should not be recognized until it is probable that a business entity will comply with the conditions attached to the grant and the grant will be received. Additionally, the ASU requires that a grant related to an asset be recognized on the balance sheet as the business entity incurs the related costs for which the grant is intended to compensate either as deferred income or an adjustment to the cost basis of the related asset. A grant related to income or a grant recognized as deferred income should be recognized in earnings on a systematic and rational basis over the periods in which the related costs are incurred that the grant is intended to compensate.

The ASU is effective for H2O America for annual reporting periods beginning after December 15, 2028 and interim reporting periods within those annual reporting periods. Early adoption is permitted.

Retrospective adoption with modified prospective and modified retrospective application also permitted.

H2O America is currently evaluating the impact of ASU 2025-10 on its financial statements and will adopt ASU 2025-10 in fiscal year ended December 31, 2029.

ASU 2025-11 “Interim Reporting (Topic 270)”

The ASU provides clarity about the current requirements, rather than an evaluation of whether to expand or reduce interim disclosure requirements. The ASU includes a disclosure principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The intent of the disclosure principle, which is modeled after a previous SEC disclosure requirement, is to help entities determine whether disclosures not specified in Topic 270 should be provided in interim reporting periods.

The ASU is effective for H2O America for interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted.

Prospective, with retrospective application also permitted.

H2O America is currently evaluating the disclosure impact of ASU 2025-11; however, the standard is not expected to impact the consolidated financial position, results of operations or cash flows.
