The Company had an effective tax rate of (4.0)% and (3.3)% for the three and nine months ended September 30, 2025, respectively, and (4.6)% and (2.3)% for the three and nine months ended September 30, 2024, respectively. The Company continues to incur U.S. operating losses and has minimal profits in its foreign jurisdictions.

During the three and nine months ended September 30, 2025 and 2024, the Company evaluated all available evidence, both positive and negative, including historical levels of income, along with expectations and risks associated with estimates of future taxable income, and determined that it is more likely than not that its net deferred tax assets will not be realized in the United States. Due to uncertainties surrounding the realization of the deferred tax assets, the Company continues to maintain a full valuation allowance against its net deferred tax assets within the United States.

On July 4, 2025, the One Big Beautiful Bill Act (“the OBBBA”) was signed into law. The OBBBA introduces multiple tax law and other legislative changes, which may be subject to further clarification and the issuance of interpretive guidance. The new legislation did not have a material impact on the Company’s consolidated financial statements. The Company will continue to monitor developments on additional guidance and legislative changes.
