(1) For the year ended May 31, 2026, state taxes in California, Illinois, and New York make up greater than 50% of the tax effect in this category. For the year ended May 31, 2025, state taxes in California and Illinois make up greater than 50% of the tax effect in this category. For the year ended May 31, 2024, state taxes in California, Wisconsin, New York, and Illinois make up greater than 50% of the tax effect in this category. The above effective tax rate attributable to controlling interest excludes any impact from the inclusion of net earnings attributable to noncontrolling interests in our consolidated statements of earnings. The effective tax rate upon inclusion of net earnings attributable to noncontrolling interests was 23.0% for fiscal 2026. Net earnings attributable to noncontrolling interests are primarily a result of our acquisition of Halo in fiscal 2024. The earnings attributable to the noncontrolling interests in Halo do not generate tax expense to us since the investors in Halo’s operations are taxed directly based on the earnings attributable to them.
