As previously reported by UY Scuti Acquisition Corp. (the “Company”) in its Current Report on Form 8-K filed on April 6, 2026, effective as of March 31, 2026, Sun Peisha (the “Lender”), an individual and the designee of UY Scuti Investments Limited (the “Sponsor”) loaned the Company the aggregate amount of $450,000, which amount was deposited into the trust account established by the Company in connection with its initial public offering pursuant to the Company’s Second Amended and Restated Memorandum and Articles of Association, as amended, and the amendment to the Trust Agreement governing the trust account (the “Trust Account”), in order to extend the time that the Company has to consummate an initial business combination for the first three-month extension period to July 1, 2026 (the “First Extension Loan”).

On April 25, 2026, a promissory note, which is dated as of April 13, 2026, evidencing the first Extension Loan was executed by the Company and the Lender (the “First Extension Note”). The First Extension Note is unsecured, bears no interest and provides that the Company shall repay the outstanding principal balance of such note on the date on which the Company consummates the business combination transaction contemplated by that certain Agreement and Plan of Merger dated July 18, 2025 by and among Isdera Group Limited, Xinghui Automotive Technology (Hainan) Co., Ltd., and UY Scuti Acquisition Corp., and the other parties thereto. On such maturity date, the entire outstanding principal balance of the First Extension Note shall be converted into units of the Company’s securities at a conversion price of $10.00 per unit, with each unit consisting of one Ordinary Share of the Company and one right to receive one-fifth of one Ordinary Share of the Company.

The disclosures set forth in this Item 2.03 regarding the First Extension Note are intended to be a summary only and are qualified in their entirety by reference to the First Extension Note. The issuance of the First Extension Note was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as amended. A copy of the First Extension Note is attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
