SemiLEDs Corp Income Taxes Disclosure

10. INCOME TAXES

Income taxes are recognized for the amount of taxes payable for the current year and for the impact of deferred tax assets and liabilities, which represent future tax consequences of events that have been recognized differently in the financial statements than for tax purposes. Deferred tax assets and liabilities are established using the enacted statutory tax rates and are adjusted for any changes in such rates in the period of change.

United States

SemiLEDs Corporation is incorporated in the United States of America and is subject to United States federal taxation. No provisions for income taxes have been made as the Company has no taxable income for the period.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act included significant changes to the U.S. corporate income tax system including, among other things, lowering the U.S. statutory federal tax rate to 21%. The reduction of the U.S. corporate tax rate caused the Company to adjust its U.S. deferred tax assets and liabilities to the lower federal rate of 21% in the fiscal year ended August 31, 2019. The Tax Act also added many new provisions, including a one-time repatriation tax on deemed repatriation of historical earnings of foreign subsidiaries (“transition tax”), changes to bonus depreciation, limits on deductions for executive compensation and interest expense, a tax on global intangible low-taxed income (“GILTI”), the base erosion anti-abuse tax (“BEAT”) and a deduction for foreign-derived intangible income. The Company has

elected to account for the tax on GILTI and BEAT as a period cost and thus has not adjusted any net deferred tax assets of its foreign subsidiaries for the new tax. However, the Company has considered the potential impact of GILTI and BEAT on its U.S. federal net operating loss (“NOL”) carryforward and determined that the projected tax benefit to be received from its NOL carryforward may be reduced due to these provisions.

The changes included in the Tax Act are broad and complex. The SEC issued Staff Accounting Bulletin No. 118 (SAB 118), as amended by ASU 2018-05, which provides guidance for companies related to the Tax Act. ASU 2018-05 allows for a measurement period of up to one year after the enactment date of the Tax Act to finalize the recording of the related tax impacts. The Company’s accounting for the tax effects of the Tax Act were completed in fiscal 2019. Although the Company believes the effects of the Tax Act have been appropriately recorded, it will continue to monitor, among other things, changes in interpretations of the Tax Act, any legislative action arising because of the Tax Act and any changes in accounting standards for income taxes or related interpretations in response to the Tax Act. The Company intends to assess the impact of any such changes in legislative interpretations or standards and adjust its provision as new information becomes available.

In accordance with SAB 118, the Company has made reasonable estimates related to (1) the remeasurement of its U.S. deferred tax balances for the reduction in the statutory tax rate, (2) the liability for the transition tax and (3) the partial valuation allowance recorded against its federal NOL carryforward due to the impact of the GILTI and BEAT provisions. In fiscal 2025, the Company determined that there were no material changes to the provisional amounts recorded as of August 31, 2025.

Taiwan

The Company’s loss before income taxes is primarily derived from the operations in Taiwan, and income tax expense is primarily incurred in Taiwan.

As a result of amendments to the “Taiwan Income Tax Act” enacted by the Office of the President of Taiwan on February 7, 2018, the statutory income tax rate increased from 17% to 20% and the undistributed earning tax, or a surtax, decreased from 10% to 5% effective from January 1, 2018. As a result, the statutory income tax rate in Taiwan is 20% for the years ended August 31, 2025 and 2024. An additional surtax, of which rate was reduced from 10% to 5% being applied to the Company starting from September 1, 2018, is assessed on undistributed income for the entities in Taiwan, but only to the extent such income is not distributed or set aside as a legal reserve before the end of the following year. The 5% surtax is recorded in the period the income is earned, and the reduction in the surtax liability is recognized in the period the distribution to stockholders or the setting aside of legal reserve is finalized in the following year.

A valuation allowance is provided when it is more likely than not that the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible and operating loss carryforwards utilizable. Management considers the scheduled reversal of deferred tax liabilities, carryback availability, projected future income, and tax-planning strategies in making this assessment. The Company established full valuation allowances to offset all of its deferred tax assets due to the uncertainty of realizing future tax benefits from its net operating loss carryforwards and other deferred tax assets.

Unrecognized Tax Benefits

On December 22, 2017, the U.S. Tax Cuts and Jobs Act was adopted, which among other effects, reduced the U.S. federal corporate income tax rate to 21% from 34% (or 35% in certain cases) beginning in 2018, requires companies to pay a one-time transition tax on certain unrepatriated earnings from non-U.S. subsidiaries that is payable over eight years, makes the receipt of future non-U.S. sourced income of non-U.S. subsidiaries tax-free to U.S. companies and creates a new minimum tax on the earnings of non-U.S. subsidiaries relating to the parent’s deductions for payments to the subsidiaries. Provisional estimate of the Company is that no tax will be due under this provision.

As of August 31, 2025 and 2024, the Company had no unrecognized tax benefits.

The Company is subject to taxation in the United States and various states and certain foreign jurisdictions. As of August 31, 2025, the 2020 through 2023 tax years remain subject to examination by the U.S. tax authorities. With few exceptions, as of August 31, 2025, the Company is no longer subject to U.S. federal, state, local, or foreign examinations by tax authorities for tax years before 2020. Below is a summary of open tax years by major tax jurisdiction:

The Company is not currently under examination by income tax authorities in any federal, state or foreign jurisdictions. The Company does not expect that the total amount of unrecognized tax benefits will change significantly within the next 12 months.
