On October 8, 2025, the Company consummated the IPO of 11,500,000 units (the “Units”), including full exercise of the overallotment option. Each Unit consists of one Class A ordinary share (“Ordinary Share”) and one-seventh (1/7) of one right (“Right”) to receive one Ordinary Share upon the consummation of an initial business combination. The Units were sold at an offering price of $10.00 per Unit, generating gross proceeds of $115,000,000.

As of October 9, 2025, a total of $115,000,000 of the net proceeds from the IPO and the Private Placement (as defined below) were deposited in a trust account established for the benefit of the Company’s public shareholders. An audited balance sheet as of October 8, 2025 reflecting receipt of the proceeds upon consummation of the IPO and the Private Placement will be filed within 4 business days of the consummation of the IPO.

Simultaneously with the closing of the IPO, the Company consummated the private placement (“Private Placement”) with the Sponsor and CCM, of an aggregate of 360,000 private units (the “Private Units”) at a price of $10.00 per Private Unit, generating total gross proceeds of $3,600,000.

The Private Units are identical to the Units sold in the IPO. Additionally, the Sponsor and CCM 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 the completion of the Company’s initial business combination. The Sponsor and CCM were granted certain demand and piggyback registration rights in connection with the purchase of the Private Units.
