The effective income tax rates for the total provision (benefit) for the three and nine months ended September 30, 2025 are greater than the federal statutory rate, primarily due to the effect of state income taxes, including a $25 million state income tax provision related to an increase in our estimate of the deferred state income tax rate (net of federal benefit). The effective income tax rates for the total provision (benefit) for the three and nine months ended September 30, 2024 are greater than the federal statutory rate, primarily due to the effect of state income taxes. On July 4, 2025, the One Big Beautiful Bill Act was enacted. While the new law is not expected to have a significant impact on Williams’ federal income tax provision, Williams does expect a temporary deferral of federal income tax payments as a result of permanently restoring full bonus depreciation of certain business property and excluding tax depreciation and amortization in the calculation of the business interest expense limitation.
