As previously reported in its Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on June 25, 2026, on June 18, 2026, Range Capital Acquisition Corp. (the “Company”) issued an unsecured promissory note (the “Note”) in the principal amount of up to $540,000 to its sponsor, Range Capital Acquisition Sponsor, LLC (the “Sponsor”), to be drawn down in connection with the previously announced contributions of up to $60,000 per month (the “Contributions”) by the Sponsor or its designees to the trust account established in connection with the Company’s initial public offering (the “Trust Account”). The Note does not bear interest and the principal balance will be payable on the earlier of: (i) the date on which the Company consummates its initial business combination and (ii) the date that the winding up of the Company is effective. In the event that the Company does not consummate an initial business combination, the Note will be repaid only from amounts remaining outside of the Trust Account, if any. The Note is subject to customary events of default, the occurrence of certain of which automatically triggers the unpaid principal balance of the Note and all other sums payable with regard to the Note becoming immediately due and payable. On August 21, 2026, $60,000 was drawn down from the Note and deposited into the Trust Account, and an aggregate of $180,000 was outstanding under the Note.

The issuance of the Note was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as amended.
