Income taxes

As of March 31, 2026 and December 31, 2025, a valuation allowance was recorded against all deferred tax assets due to our cumulative net loss position. Provision for income taxes for the three months ended March 31, 2026 was $1,000 and benefit for income taxes for the three months ended March 31, 2025 was $5,000.

As of December 31, 2025, we had federal and state net operating loss carryforwards (“NOLs”) of approximately $483.7 million and $9.7 million, respectively. The federal NOLs began expiring in 2021 and the state NOLs began expiring in 2020. As of December 31, 2025, we had federal and state tax credit carryforwards of approximately $10.3 million and $1.9 million, respectively. The federal tax credit carryforwards began expiring in 2021 and the state tax credits will begin expiring in 2028.

Utilization of NOLs may be subject to an annual limitation due to the ownership change limitations provided by Section 382 of the Internal Revenue Code of 1986, as amended, and similar state provisions. We have not performed a detailed analysis to determine whether an ownership change has occurred. Such a change of ownership would limit our utilization of the NOLs and could be triggered by subsequent sales of securities by us or our stockholders.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA includes significant tax-related 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, including the deduction of certain R&D costs. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The impacts of the OBBBA were taken into account in our provision for income taxes for fiscal year 2025. Because a valuation allowance has been recorded against all deferred tax assets, the impacts of the OBBBA were not material to our consolidated financial statements or related disclosures.
