All of the Company’s carryforward tax losses will be indefinitely carried forward, with the exception of federal U.S. NOLs in the amount of $0.2 million as of December 31, 2025, which will begin to expire in 2037 and state NOLs in the amount of $21.9 million as of December 31, 2025, which will begin to expire in 2036. Also, as of December 31, 2025, the Company had orphan drug and research and development credits in the U.S. in the amount of $27.2 million which will begin to expire in 2035 and research and development credits of $5.9 million in the UK which can be carried forward indefinitely. The U.S. NOLs and UK carryforward tax losses may become subject to an annual limitation in the event of certain cumulative changes in the ownership interest of significant shareholders, as defined under Section 382 of the Internal Revenue Code, as well as UK tax rules. This could limit the amount of NOLs and carryforward tax losses that the Company can utilize annually to offset future taxable income or tax

liabilities. As of December 2024, the Company had performed such an analysis and determined that there were no limitations in the UK and U.S.

The Company’s pre-tax income (loss) is as follows (in thousands):

ASC 740 requires a valuation allowance to reduce the deferred tax assets reported if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. After consideration of all the evidence, both positive and negative, the Company has recorded a full valuation allowance, after consideration of the reversal of the deferred tax liabilities for the ROU assets, fixed assets, and other deferred tax liabilities against its deferred tax assets at December 31, 2025 and 2024 because the Company's management has determined that it is more likely than not that these assets will not be fully realized.

As of December 31, 2025 and 2024, the Company recorded unrecognized tax positions of $2.7 million and $2.2 million, respectively. The unrecognized tax positions are netted with deferred tax assets above with a full valuation allowance. The changes to unrecognized tax positions for 2025 and 2024 were as follows (in thousands):

The Company will recognize interest and penalties related to uncertain tax positions in income tax expense. As of December 31, 2025 and 2024, the Company had no accrued interest or penalties related to uncertain tax positions and no amounts have been recognized in the Company's statements of operations and comprehensive loss.

The Company files income tax returns in the United States, UK, various foreign jurisdictions and various U.S. state jurisdictions. In the U.S., all years remain subject to examination. The earliest year subject to examination in the UK is 2022.

MeiraGTx Holdings plc is a UK tax resident with no earnings in its foreign subsidiaries and the Company does not expect any temporary basis difference in its investment in these subsidiaries to reverse in the foreseeable future. Therefore, the Company has not recorded deferred taxes on the outside basis difference in its foreign subsidiaries. It is not probable to compute the amounts, if any.

In July 2025, U.S. tax legislation known as the One Big Beautiful Bill Act, or OBBBA, was signed into law which makes permanent many of the tax provisions enacted in 2017 as part of the Tax Cuts and Jobs Act, or TCJA, that were set to expire at the end of 2025. Under OBBBA, domestic research and development costs incurred in tax years beginning after 2024 may be immediately deducted or, at the taxpayer’s election, capitalized and amortized. The OBBBA also provides several options for transitioning to the new rules for domestic research and development costs, including accelerated recovery of previously capitalized costs (beginning in 2025) for all taxpayers. Pursuant to TCJA Section 174, the Company elected to amortize its previously capitalized domestic research and development expenditures ratably over a two-year period. Following the enactment of Section 174A, the Company plans to adopt the revised method permitting the deduction of domestic research and development expenditures in the year incurred. Accordingly, domestic research and development expenses incurred during fiscal year 2025 were fully deducted for tax purposes. As the recent legislative changes did not modify the capitalization requirements applicable to foreign research and development expenditures, the Company evaluated its foreign research and development costs for the year ended December 31, 2025. The other provisions of the OBBBA did not have a material effect on the Company’s Consolidated Financial Statements for the fiscal year ended December 31, 2025.
