Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant. Extension of the Termination Date An aggregate of $34,330.96 (the “ Extension Payment ”) has been deposited into the trust account of Aimei Health Technology Co., Ltd (the “ Company ”) for its public shareholders, representing the lessor of (i) $80,000 for all outstanding public shares and (ii) $0.033 for each outstanding public share for each monthly extension, which enables the Company to further extend the period of time it has to consummate its initial business combination by one month (the “ Extension ”) from July 6, 2026 to August 6, 2026 (the “ Termination Date ”). The Extension is the twentieth extension permitted under the Amended and Restated Articles of Association of the Company currently in effect. Promissory Note In connection with the Extension, the Company issued, on July 6, 2026, an unsecured promissory note in the total principal amount of $34,330.96 (the “ Promissory Note ”) to Aimei Health Ltd, a Cayman Islands exempted company (the “ Payee ”), to fund the Extension Payment. The Promissory Note does not bear interest and the principal thereunder becomes due and payable upon the date on which the Company consummates a business combination with United Hydrogen (the “ Business Combination ”). The Payee has the right, but not the obligation, to convert the Promissory Note, in whole or in part, into private units of the Company, at a price of $10.00 per unit, each consisting of one ordinary share and one right to receive one-fifth (1/5) of one ordinary share of the Company, immediately prior to the consummation of the Business Combination, by providing the Company with written notices of their intention to convert the Promissory Note at least two business days prior to the closing of the Business Combination. The foregoing description of the Promissory Note is not complete and is qualified in its entirety by reference to the text of such document, which is filed as Exhibit 10.1 hereto and which is incorporated herein by reference.
