12. Income Taxes
Our provision for income taxes for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that arise during the period. Each quarter, we update the estimate of the annual effective tax rate, and if the estimated annual effective tax rate changes, we make a cumulative adjustment in such period. For the three months ended March 31, 2026 and 2025, income tax expense (benefit) was immaterial.
We have a full valuation allowance against our United States federal and state deferred tax assets and will continue to maintain it until there is sufficient evidence to support the future utilization of these assets. Given our recent history of generating net income in the United States, we believe that there is a reasonable possibility that sufficient positive evidence may become available within the next 12 months to allow us to release a significant portion of the valuation allowance in the United States. The reversal would result in a significant income tax benefit in the period when we release it. However, the exact timing and amount of the valuation allowance release are subject to change based on a number of factors, including but not limited to, the level of profitability (income before income taxes adjusted for permanent differences) that we are able to accurately
forecast, as well as the amount of our tax deductible stock-based compensation, which is dependent upon our publicly traded share price, and macroeconomic conditions, among other factors.
