Income Taxes INCOME TAXES
Income tax provisions for interim quarterly periods are based on an estimated annual effective income tax rate calculated separately from the effect of significant, infrequent or unusual discrete items related specifically to interim periods. The following summarizes income tax expense and the effective tax rate in each interim period:

The year-over-year change in the effective tax rate for the three months ended June 30, 2026 reflected lower nondeductible transaction costs associated with the Breeze acquisition as acquisition-related activities were substantially completed.

The year-over-year change in the effective tax rate for the nine months ended June 30, 2026, was primarily attributed to the Breeze acquisition and the immediate FTC-required divestiture of 45 acquired stores. The $57.9 million pre-tax loss on divestiture did not generate a tax benefit; rather, nondeductible goodwill drove an unfavorable tax effect and contributed to a taxable gain on the divestiture that resulted in $6.3 million of income tax expense in the nine months ended June 30, 2026. Additionally, certain transaction costs became nondeductible in connection with the acquisition close and increased income tax expense by $4.3 million in the current year-to-date period.
