Our income tax provision reflects an effective tax rate on pre-tax income of 26% and 20% for the three and six months ended March 31, 2026 and March 31, 2025. The effective tax rates for each period were favorably impacted by the estimated Research and Development (R&D) Tax Credit, which was offset by the tax expense related to certain nondeductible items. In addition, discrete items related to the vesting of RSUs recorded in the first quarters of Fiscal 2026 and Fiscal 2025 favorably impacted the effective tax rate for the six months ended March 31, 2026 and March 31, 2025.
