As of May 1, 2026, a total of $60,000,000 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 May 1, 2026 reflecting receipt of the proceeds upon consummation of the IPO and the Private Placement will be filed within four (4) business days of the consummation of the IPO.

Item 3.02. Unregistered Sales of Equity Securities.

Simultaneously with the closing of the IPO, the Company consummated a private placement (the “Private Placement”) with Mountain Crest Holdings 6 LLC, the Company’s sponsor (the “Sponsor”), and D. Boral Capital LLC (“D. Boral”), pursuant to which the Sponsor purchased an aggregate of 90,000 private units (the “Private Units”) at a price of $10.00 per Private Unit, generating total proceeds of $900,000. On April 29, 2026, the Company elected to satisfy a portion of the underwriting fee owed to D. Boral by issuing 65,000 Private Placement Units at a price of $10.00 per unit. No discounts or commissions were paid in connection with the sale of the Private Placement Units.

The Private Units are identical to the Units sold in the IPO. Additionally, the Sponsor 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 was granted certain demand and piggyback registration rights in connection with the purchase of the Private Units.

The Private Units were issued pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended, as the transactions did not involve a public offering.
