The effective tax rates for the three and six months ended June 30, 2026 was(133.3)% and 5.8%, respectively, compared to 17.6% and 21.7%, respectively, for the corresponding periods of 2025. In general, the Company's effective tax rates differ from the U.S. statutory rate due to recurring items, such as differing tax rates on income earned in foreign jurisdictions, nondeductible expenses and state income taxes. The effective tax rates for the three and six months ended June 30, 2026 were impacted by changes in forecasted annual earnings and the geographic mix of those earnings, which resulted in a change in the estimated annual effective tax rate from the estimate used during the first quarter of 2026. The revised estimated annual effective tax rate contributed to income tax expense during the second quarter of 2026 despite a pretax loss for the quarter, resulting in a negative effective tax rate for the three months ended June 30, 2026.
