Income Taxes	9 Months Ended
Income Taxes	Sep. 30, 2025
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company calculates its tax provision in interim periods using its best estimate of the effective tax rate expected for the full year. For the three months ended September 30, 2025 and 2024, the Company recorded income tax expense of $3.9 million and $3.7 million, respectively. The effective tax rate was approximately 20.6% for the three months ended September 30, 2025, compared to 23.6% for the three months ended September 30, 2024. The effective tax rate for the three months ended September 30, 2025 differs from the statutory tax rate of 21.0% primarily due to estimated non-deductible excess officer compensation, state taxes, and non-deductible expenses, partially offset by research and development credits net of related uncertain tax positions and expected excess tax benefits on the vesting of stock-based compensation. The effective tax rate for the three months ended September 30, 2024 differs from the statutory tax rate of 21.0% primarily due to state taxes, non-deductible expenses, and the current period impact from a change of estimate in the prior year. For the nine months ended September 30, 2025 and 2024, the Company recorded income tax expense of $10.5 million and $7.6 million, respectively. The effective tax rate was approximately 21.3% for the nine months ended September 30, 2025 compared to 23.7% for the nine months ended September 30, 2024. The effective tax rate for the nine months ended September 30, 2025 differs from the statutory tax rate of 21.0% primarily due to estimated non-deductible excess officer compensation, state taxes, and non-deductible expenses, partially offset by research and development credits net of related uncertain tax positions and expected excess tax benefits on the vesting of stock-based compensation. The effective tax rate for the nine months ended September 30, 2024 differs from the statutory tax rate of 21.0% primarily due to state taxes, non-deductible expenses, and the current period impact from a change of estimate in the prior year. On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was signed into law, enacting significant changes to the 2017 Tax Cuts and Jobs Act (“TCJA”). Such changes include the restoration of 100% bonus depreciation, which was scheduled to phase out in 2027 under the TCJA. The OBBBA also permits immediate expensing of research and development expenditures previously capitalized under the TCJA and modifies various components of the international tax framework. The legislation has multiple effective dates, with some provisions taking effect in 2025 and others phased in through 2027. In accordance with ASC 740, the company has recognized the effects of the enacted provisions and determined the legislation did not have a material impact on the company’s income tax expense or effective tax rate for the three or nine months ended September 30, 2025, respectively. As of September 30, 2025, the Company had unrecognized tax benefits of $1.3 million, including $0.2 million of interest and penalties, related to mandatory capitalization of research and development costs and research and development credits claimed on current year and prior year amended income tax returns. The Company’s policy is to record interest and penalties related to uncertain tax positions in income tax expense. No uncertain tax positions or related interest and penalties were established in prior periods.
