Note 16.  Income Taxes

​​ For the three months ended June 30, 2025 and 2024, the effective tax rate varied from the federal statutory rate of 21% primarily due to the change of the valuation allowance on federal, state, Taiwan, and China deferred tax assets ("DTA"). 

The Company continually monitors and performs an assessment of the realizability of its DTAs, including an analysis of factors such as future taxable income, reversal of existing taxable temporary differences, and tax planning strategies. In assessing the need for a valuation allowance, the Company considered both positive and negative evidence related to the likelihood of realization of deferred tax assets using a “more likely than not” standard. In making such assessment, more weight was given to evidence that could be objectively verified, including recent cumulative losses. Based on the Company’s review of this evidence, management determined that a full valuation allowance against all of the Company’s net deferred tax assets at  June 30, 2025 was appropriate. 

On July 4, 2025, new U.S tax legislation was signed into law (known as the "One Big Beautiful Bill Act" or "OBBBA") which includes, among other provisions, changes to the U.S. corporate income tax system including the allowance of immediate expensing of qualifying research and development expenses and permanent extensions of certain provisions within the Tax Cuts and Jobs Act.  In addition, the OBBBA makes changes to certain U.S. corporate and international tax provisions which are generally not effective until 2026.  For example, as a U.S. domiciled company, the income from the Company's foreign subsidiaries is subject to the U.S. tax provisions under Internal Revenue Code Section 951A, which, as amended by the OBBBA, generally will require that net Controlled Foreign Corporation (“CFC”) tested income (formerly referred to as global intangible low-taxed income, or GILTI) be included in the taxable income of U.S. entities for tax years after December 31, 2025. We are currently evaluating the impact of the new legislation but does not expect it to have a material impact on our financial statements since we currently have a full valuation allowance applied against our deferred tax assets.
