Note 9 — Income Taxes
The following table summarizes the Company's income tax expense and effective tax rates for the three and six months ended June 30, 2026 and 2025:
The Company’s quarterly income tax provision is calculated under the discrete method, which treats the interim period as if it were the annual period and determines the income tax expense or benefit on that basis. The discrete method is applied when application of the estimated annual effective income tax rate is impractical because it is not possible to reliably estimate the annual effective tax rate. The Company believes, at this time, the use of this discrete method is more appropriate as the annual effective income tax rate cannot be reliably estimated given the Company's full valuation allowance recorded on its net deferred tax assets and annual utilization limitations that prevent the Company from fully offsetting its expected current income tax liabilities with its available net operating losses and income tax credits.
The Company's quarterly income tax provision calculated under the discrete method for the three months and six months ended June 30, 2026 captures the income tax effects of the One Big Beautiful Bill Act (“OBBBA”), which was enacted on July 4, 2025. The Company's current income tax expense for the three months and six months ended June 30, 2026 includes the benefit of the OBBBA restoring the ability to immediately deduct domestic research & experimental expenditures under Internal Revenue Code Section 174. The Company did not record any deferred income tax expense or benefit related to the OBBBA tax law changes during the period ended June 30, 2026 as the Company continues to record a full valuation allowance against its net deferred tax assets.
The effective tax rate for the three months and six months ended June 30, 2026 varies from the three months and six months ended June 30, 2025 primarily as a result of the Company's valuation allowance recorded against its net deferred tax assets and annual tax attribute utilization limitations that result in current income tax expense. Taxes paid during the six months ended June 30, 2026 and 2025 were $85 and $89, respectively. Tax refunds received during the six months ended June 30, 2026 and 2025 were $109 and $0, respectively.
