8. Income Taxes

The Company’s quarterly provision for income taxes is measured using an annual effective tax rate, adjusted for discrete items within the period presented. To determine the annual effective tax rate, the Company estimates both the total income (loss) before income taxes for the full year and the jurisdictions in which that income (loss) is subject to tax. The actual effective tax rate for the full year* may*differ from these estimates if income (loss) before income taxes is greater than or less than what was estimated or if the allocation of income (loss) to jurisdictions in which it is taxed is different from the estimated allocations.

The Company's effective tax rates for thethree andnine months ended* September 30, 2025* were -561.7% and -486.2%, respectively. The Company's effective tax rates for thethree andnine months ended* September 30, 2024* were 34.8% and 35.2%, respectively. The effective tax rates differed from the statutory tax rate of 21% primarily due to the impact of uncertain tax positions, including the reversal of a previously recorded uncertain tax position from tax year2021 as the statute of limitations expired for the related matter (approximately -599.2% and -553.8% of Income from operations before income taxes for thethree andnine months ended* September 30, 2025*, respectively), and state income taxes.
