0.05)% for the three and nine months ended September 30, 2025 and 2024, respectively. The Company has historically incurred U.S. operating losses prior to the nine months ended September 30, 2025 and has minimal profits in its foreign jurisdictions.The Company updates its estimate of the annual effective tax rate each quarter and makes a cumulative adjustment in such period. The Company recorded immaterial amounts for the three and nine months ended September 30, 2025 and 2024, respectively. Income tax expense (benefit) consists primarily of income taxes for U.S. federal and the states in which the Company conducts business. Due to the Company’s history of losses in the United States, a full valuation allowance on substantially all of the Company’s deferred tax assets, including net operating loss carryforwards, research and development tax credits, and other book versus tax differences, was maintained. On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The enactment of the OBBBA did not result in a material impact to our provision for income taxes for the three months ended September 30, 2025 given we maintain a full valuation allowance on our federal deferred tax assets. We are currently assessing the long term impact the OBBBA may have on our financial condition, results of operations, cash flows, and effective tax rate.
