MasterBrand MBC Effective tax rates

The effective tax rate for the period reflects the impact of the merger of American Woodmark on May 28, 2026. The inclusion of American Woodmark’s earnings, nondeductible expenses, tax attributes, and jurisdictional mix resulted in a net reduction of the tax benefit recognized during the period. The effective income tax rates for the thirteen weeks ended June 28, 2026 and June 29, 2025, were (18.8) percent and 23.9 percent, respectively. The change in the effective income tax rate between the periods was primarily attributable to changes in pretax income (loss) relative to permanent tax adjustments, including a reduction in the tax benefit associated with nondeductible compensation, nondeductible acquisition-related transaction costs, deferred tax adjustments related to foreign tax elections, foreign taxes and the mix of earnings in jurisdictions with differing tax rates, partially offset by increased benefit from state and local income taxes, foreign exclusions and research and development tax credits.
