Item 1.01. Entry into a Material Definitive Agreement.

On June 11, 2026, Melar Acquisition Corp. I, a Cayman Islands exempted company (the "Company"), issued a promissory note (the "Note") in the aggregate principal amount of up to $1,500,000 to Melar Acquisition Sponsor I LLC, the Company's sponsor (the "Sponsor").

The Note was issued in connection with advances the Sponsor has previously made and may make in the future to the Company for working capital expenses. As of the date hereof, the Sponsor has advanced $223,079.12 to the Company under the Note.

The Note is interest bearing at 17.5% per annum and is repayable in full upon the earlier of (i) the date on which the Company consummates its initial business combination (the "Business Combination") and (ii) the date of liquidation of the Company. If, prior to the Business Combination, the principal balance of this Note has not been paid in full, then, at the Sponsor's option and subject to certain conditions, up to $1,500,000 of the unpaid principal amount of the Note may be converted into warrants of the Company (the "Conversion Warrant") to purchase Class A ordinary shares, par value $0.0001 per share, of the Company (the "Class A Ordinary Shares") at a conversion price of $1.00 per Conversion Warrant. The Conversion Warrants shall be identical to the warrants issued by the Company in a private placement upon consummation of its initial public offering. The Conversion Warrants and their underlying securities are entitled to the registration rights set forth in 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 (the "Securities Act").

The foregoing description is qualified in its entirety by reference to the Note, a copy of which is attached as Exhibit 10.1 hereto and is incorporated herein by reference.
