Income Taxes | 6. Income Taxes ​ The Company has no income tax expense due to operating losses incurred for the three and six months ended June 30, 2026 and 2025. The Company has provided a valuation allowance for the full amount of the net deferred tax assets as, based on all available evidence, it is considered more likely than not that all the recorded deferred tax assets will not be realized in a future period. Realization of the future tax benefits is dependent on many factors, including the Company’s ability to generate taxable income within the net operating loss carryforward period. Under the provisions of the U.S. Internal Revenue Code and Sweden tax law, certain changes in the Company’s ownership, including a sale of the Company or significant changes in ownership due to sales of equity, may have limited, or may limit in the future, the amount of net operating loss carryforwards that could be used annually to offset future taxable income. For U.S. and Swedish income tax purposes, the Company has not completed a study to assess whether a change of control has occurred or whether there have been changes of control since the Company’s formation due to the complexity and cost associated with such study and because there could be additional changes of control in the future. As a result, the Company is not able to estimate the effect of the change in control, if any, on the Company’s ability to utilize U.S. or Swedish net operating losses or other tax attribute carryforwards in the future. For Swedish income tax purposes, the Company’s net operating losses may be subject to limitations in accordance with the country’s group contribution restriction laws. The Company files tax returns in Sweden, the United States, Massachusetts and Pennsylvania. Income tax returns prior to 2022 in the United States and Massachusetts are no longer subject to examination and income tax returns prior to 2019 are no longer subject to examination in Sweden. The Company is not currently under examination by the IRS or any other jurisdictions for any tax years. As tax law is complex and often subject to varied interpretations, it is uncertain whether some of the Company’s tax positions will be sustained upon examination. Tax liabilities associated with uncertain tax positions represent unrecognized tax benefits, which arise when the estimated benefit recorded in the Company’s financial statements differs from the amounts taken or expected to be taken in a tax return because of the uncertainties described above. Substantially all of these unrecognized tax benefits, if recognized, would benefit the Company’s effective income tax rate. As of June 30, 2026 and December 31, 2025, the Company had approximately $0.1 million of liabilities related to uncertain tax positions. As the Company’s uncertain tax positions can be offset by available net operating losses, the Company did not recognize interest and penalties for 2026 and 2025. On July 4, 2025, the “One Big Beautiful Bill Act” (OBBBA) was enacted into law. The legislation made several changes to the U.S. tax code, including the return of 100% bonus depreciation, the ability to immediately deduct domestic research and development costs, a more favorable rule for deducting interest expenses, and updates to international tax rules around global intangible low-taxed income and foreign-derived intangible income. The Company has evaluated the impact of the OBBBA and determined it will have an immaterial impact on the consolidated financial results. ​
