On March 12, 2026, the Company consummated its IPO, which consisted of 12,000,000 units (the “Units”). Each Unit consists of one Class A ordinary share, $0.0001 par value (“Class A Ordinary Share”) and one right to receive one-fifth of one Class A ordinary share (each, a “Share Right”) at the closing of the Company’s initial business combination. The Units were sold at an offering price of $10.00 per Unit, generating gross proceeds of $120,000,000.

 

In connection with the IPO, the Company entered into the following agreements, forms of which were previously filed as exhibits to the Company’s Registration Statements, filed with the SEC:

 

●Underwriting Agreement, dated March 12, 2026, by and between the Company and D. Boral Capital LLC, as representative of the underwriters in the IPO (“D. Boral”), a copy of which is attached as Exhibit 1.1 hereto and incorporated herein by reference;

Item 3.02. Unregistered Sales of Equity Securities.

 

Simultaneously with the closing of the IPO, the Company consummated a private placement (the “Private Placement”) of an aggregate of 190,000 units (the “Private Units”) to the Sponsor and a certain institutional investor (the “Private Placement Investor”), at a price of $10.00 per Private Unit, generating total proceeds of $1,900,000.

Of those 190,000 Private Units, the Sponsor purchased 160,000 Private Units and the Private Placement Investor purchased 30,000 Private Units.

 

The Private Units are identical to the Units sold in the IPO except with respect to certain registration rights and transfer restrictions, as described in the Registration Statement. Additionally, such holders agreed not to transfer, assign or sell any of the Private Units or underlying securities (except in limited circumstances, as described in the Registration Statement) until 30 days after the completion of the Company’s initial business combination. The holders were granted certain demand and piggyback registration rights in connection with the purchase of the Private Units and the underlying securities.
