7.Income Taxes

The effective income tax rate reflects the effect of federal and state income taxes on earnings and the impact of differences in book and tax accounting arising primarily from the permanent tax benefits associated with the statutory depletion deduction for mineral reserves. The effective income tax rates for continuing operations were 24.1% and 20.6% for the nine months ended September 30, 2024 and 2023, respectively. The higher 2024 effective income tax rate versus 2023 was driven by the impact of the February 2024 divestiture of the South Texas cement business and certain related ready mixed concrete operations, which reflected the write off of certain nondeductible goodwill and was treated as a discrete tax event.

The Internal Revenue Service recently announced disaster tax relief for North Carolina businesses affected by Hurricanes Debby and Helene. This relief allows the Company to defer estimated federal and certain state income, payroll and excise tax payments for the period from August 2024 through April 2025. The deferred obligation will be due May 1, 2025. The Company deferred income tax payments of $123 million under this provision as of September 30, 2024.
