Income Taxes
In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("Update 2023-09"), which expands income tax disclosure requirements to include additional information related to the rate reconciliation of our effective tax rates to statutory rates as well as additional disaggregation of taxes paid. The amendments in Update 2023-09 also remove disclosures related to certain unrecognized tax benefits and deferred taxes. Update 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. We adopted Update 2023-09 effective for this annual report for the year ended December 31, 2025

As noted above, we adopted ASU 2023-09 on a prospective basis effective January 1, 2025. The following table presents required disclosure pursuant to ASU 2023-09 and reconciles the U.S. federal statutory tax amount and rate to our actual global effective amount and rate for the year ended December 31, 2025 (in millions, except percentages):
| | | | | | | | | | | | | | |
| | Amount | | Percent |
| U.S. federal statutory tax rate | | $ | (0.59) | | | 21.00 | % |
| State and local income taxes, net of federal income tax effect (a) | | 0.03 | | | (1.13) | % |
| Tax Credits | |
| |
|
| Research and development tax credit | | (0.05) | | | 1.73 | % |
| Expiring tax credits | | 0.03 | | | (0.90) | % |

| Net loss tax expense | | 0.04 | | | (1.43) | % |
| | | | |
(a) State and local taxes in Pennsylvania and Texas made up the majority (greater than 50%) of the tax effect in this category.
The Company’s effective income tax rate for 2024 reconciles with the federal statutory tax rate as follows:
| | | | | | | | |
| | 2024 |
| Income tax expense computed at federal statutory tax rate | | 21.00 | % |
| State taxes net of federal benefit | | 0.11 | % |
| Tax credits generated | | 3.31 | % |
| Change in valuation allowance | | (23.61) | % |
| Permanent differences | | (1.86) | % |
| Expiring tax credits | | (0.28) | % |
| Deferred True-ups | | 1.67 | % |
| Net loss tax benefit | | 0.34 | % |
The Company believes that it is not more likely than not that its net deferred tax assets will be realized. As such, the net deferred tax assets are fully offset with a valuation allowance as of the periods ended December 31, 2025 and 2024.
As of December 31, 2025, the Company has general business credit carryforwards of $1.6 million. These credit carryforwards will expire in years 2027 through 2044 (in millions).
| | | | | | | | |
| Years of expiration | | Federal |
| 2026 | | 0.06 | |
| 2027-2044 | | 1.51 | |
| Total federal and state credit carryforwards | | 1.57 | |
The Company expects it will continue to pay minimal taxes in future periods through the continued utilization of net operating loss carryforwards, as it is able to achieve taxable income through its operations. The Company is no longer subject to U.S. federal tax examinations for tax years before 2021, and with few exceptions, the Company is not subject to examination by state tax authorities for tax years which ended before 2021. Loss carryforwards and credit carryforwards generated or utilized in years earlier than 2021 remain subject to examination and adjustment. During 2012, the 2009 federal tax return was examined by the Internal Revenue Service with no significant findings or adjustments. During 2025, the 2022 federal tax return was selected for examination, again with no significant findings or adjustments. The Company has no unrecognized tax benefits in 2025 and 2024.
