Note 11 — Excise Tax Payable

On August 16, 2022, the Inflation Reduction Act of 2022 (the “IR Act”) was signed into federal law. The IR Act provides for, among other things, a 1% federal excise tax on certain repurchases of stock by publicly traded U.S. domestic corporations and certain U.S. domestic subsidiaries of publicly traded foreign corporations occurring on or after January 1, 2023. The excise tax is imposed on the repurchasing corporation itself, not its shareholders from which shares are repurchased. The amount of the excise tax is generally 1% of the fair market value of the shares repurchased at the time of the repurchase. However, for purposes of calculating the excise tax, repurchasing corporations are permitted to net the fair market value of certain new stock issuances against the fair market value of stock repurchases during the same taxable year. In addition, certain exceptions apply to the excise tax. The U.S. Department of the Treasury (the “Treasury”) has been given authority to provide regulations and other guidance to carry out and prevent the abuse or avoidance of the excise tax.

On December 27, 2022, the Treasury published Notice 2023-2, which provided clarification on some aspects of the application of the excise tax. The notice generally provides that if a publicly traded U.S. corporation completely liquidates and dissolves, distributions in such complete liquidation and other distributions by such corporation in the same taxable year in which the final distribution in complete liquidation and dissolution is made are not subject to the excise tax. Although such notice clarifies certain aspects of the excise tax, the interpretation and operation of aspects of the excise tax (including its application and operation with respect to SPACs) remain unclear and such interim operating rules are subject to change.

Because the application of this excise tax is not entirely clear, any redemption or other repurchase effected by the Company, in connection with a Business Combination, extension vote or otherwise, may be subject to this excise tax. Because any such excise tax would be payable by the Company and not by the redeeming holders, it could cause a reduction in the value of the Company’s Class A common stock, cash available with which to effectuate a Business Combination or cash available for distribution in a subsequent liquidation. Whether and to what extent the Company would be subject to the excise tax in connection with a Business Combination will depend on a number of factors, including (i) the structure of the Business Combination, (ii) the fair market value of the redemptions and repurchases in connection with the Business Combination, (iii) the nature and amount of any “PIPE” or other equity issuances in connection with the Business Combination (or any other equity issuances within the same taxable year of the Business Combination) and (iv) the content of any subsequent regulations, clarifications, and other guidance issued by the Treasury. Further, the application of the excise tax in respect of distributions pursuant to a liquidation of a publicly traded U.S. corporation is uncertain and has not been addressed by the Treasury in regulations, and it is possible that the proceeds held in the Trust Account could be used to pay any excise tax owed by the Company in the event the Company is unable to complete a Business Combination in the required time and redeem 100% of the remaining Class A common stock in accordance with the Company’s amended and restated certificate of incorporation, in which case the amount that would otherwise be received by the public stockholders in connection with the Company’s liquidation would be reduced.

Any redemption or other repurchase that occurs after December 31, 2022, in connection with a Business Combination, extension vote or otherwise, may be subject to the excise tax. Whether and to what extent the Company would be subject to the excise tax in connection with a Business Combination, extension vote or otherwise would depend on a number of factors, including (i) the fair market value of the redemptions and repurchases in connection with the Business Combination, extension or otherwise, (ii) the structure of a Business Combination, (iii) the nature and amount of any PIPE or other equity issuances in connection with a Business Combination (or otherwise issued not in connection with a Business Combination, but issued within the same taxable year of a Business Combination) and (iv) the content of regulations and other guidance from the Treasury. In addition, because the excise tax would be payable by the Company and not by the redeeming holder, the mechanics of any required payment of the excise tax have not been determined. The foregoing could cause a reduction in the cash available on hand to complete a Business Combination and in the Company’s ability to complete a Business Combination.

During the second quarter of 2024, the Internal Revenue Service issued final regulations with respect to the timing and payment of the excise tax. These regulations provided that the filing and payment deadline for any liability incurred during the period from January 1, 2023 to December 31, 2023 would be October 31, 2024. Any amount of such excise tax not paid in full, will be subject to additional interest and penalties which are currently estimated at 8% interest per annum, a 0.5% underpayment penalty per month or portion of a month up to 25% of the total liability for any amount that is unpaid from November 1, 2024 until paid in full, and a failure to file penalty of 5% per month.

Prior to the consummation of the Reverse Acquisition, Bannix’s common stockholders exercised their right to redeem their shares for a pro rata portion of the funds in Bannix’s Trust Account. As a result of these redemptions, Bannix estimated the excise tax liability and applicable interest and penalties pursuant to the IR Act. At the consummation of the Reverse Acquisition, $888,332 of excise tax liability, inclusive of excise tax interest and penalties, is assumed. For the three months ended December 31, 2025 and 2024, $33,614 and $0 of interest and penalties, respectively, is estimated on the excise tax balance. As of December 31, 2025 and September 30, 2025, $976,653 and $943,039 of excise tax liabilities, respectively, inclusive of interest and penalties is recorded in the consolidated balance sheets.
