Income Taxes [Abstract]
Income Taxes	Note 16 – Income Taxes The Company’s effective tax rate was an expense of 4.5% and a benefit of 2.5% for the three and nine months ended September 30, 2025, respectively. The Company’s effective tax rate was an expense of 18.6% and 1.7% for the three and nine months ended September 30, 2024, respectively. The decrease in income tax expense in the third quarter of 2025 is primarily attributed to the net increase in tax benefit associated with the tax deduction for continued qualifying infrastructure investment, offset by decreases in both the state tax benefit and amortization of tax repairs surcredit in the Regulated Natural Gas segment based on a rate order received in September 2024. The increase in the income tax benefit for the first nine months of 2025 is primarily attributed to the release of $22,575 of income tax reserve regulatory liability in the Regulated Water segment based on the rate order received by Aqua Pennsylvania in February 2025, offset by the decreases in both the state tax benefit and amortization of tax repairs surcredit in the Regulated Natural Gas segment based on a rate order received in September 2024. In determining its interim tax provision, the Company reflects its estimated impact from its permanent and flow-through tax differences. The Company uses the flow-through method to account for the repairs tax deduction for qualifying utility infrastructure at its regulated Pennsylvania and New Jersey subsidiaries.

For states with a corporate net income tax, the state corporate net income tax rates range from 2.25% to 9.50% for all periods presented. Our effective tax rate differs from the federal statutory tax rate primarily due to flow-through tax, the amortization of deferred benefit from repair method changes, state income taxes, and other permanent book-to-tax differences.

Note 16 – Income Taxes

The Company’s effective tax rate was an expense of 4.5% and a benefit of 2.5% for the three and nine months ended September 30, 2025, respectively. The Company’s effective tax rate was an expense of 18.6% and 1.7% for the three and nine months ended September 30, 2024, respectively. The decrease in income tax expense in the third quarter of 2025 is primarily attributed to the net increase in tax benefit associated with the tax deduction for continued qualifying infrastructure investment, offset by decreases in both the state tax benefit and amortization of tax repairs surcredit in the Regulated Natural Gas segment based on a rate order received in September 2024. The increase in the income tax benefit for the first nine months of 2025 is primarily attributed to the release of $22,575 of income tax reserve regulatory liability in the Regulated Water segment based on the rate order received by Aqua Pennsylvania in February 2025, offset by the decreases in both the state tax benefit and amortization of tax repairs surcredit in the Regulated Natural Gas segment based on a rate order received in September 2024.

In determining its interim tax provision, the Company reflects its estimated impact from its permanent and flow-through tax differences. The Company uses the flow-through method to account for the repairs tax deduction for qualifying utility infrastructure at its regulated Pennsylvania and New Jersey subsidiaries.

The statutory Federal tax rate is 21.0% for the nine months ended September 30, 2025 and 2024. For states with a corporate net income tax, the state corporate net income tax rates range from 2.25% to 9.50% for all periods presented. Our effective tax rate differs from the federal statutory tax rate primarily due to flow-through tax, the amortization of deferred benefit from repair method changes, state income taxes, and other permanent book-to-tax differences.

On July 4, 2025, H.R.1 – One Big Beautiful Bill Act (“OBBBA”) was enacted into law. The OBBBA includes significant provisions such as the permanent extension of certain expiring provisions of the

2017 Tax Cuts and Jobs Act. The OBBBA did not have a significant impact to our consolidated financial statements.
