Simultaneously with the closing of the IPO, the Company completed the private sale (the “Private Placement”) of an aggregate of 665,000 units (the “Private Placement Units”). 265,000 Private Placement Units were sold to Columbus Circle 2 Sponsor Corporation LLC, the Company’s sponsor, and 400,000 Private Placement Units were sold to Cohen & Company Capital Markets, a division of Cohen & Company Securities, LLC and Clear Street LLC, the representatives of the underwriters in the IPO, in each case at a purchase price of $10.00 per Private Placement Unit, generating gross proceeds to the Company of $6,650,000.

A total of $230,000,000, or $10.00 per Unit, comprised of the net proceeds from the IPO and the sale of the Private Placement Units, was placed in a U.S.-based trust account maintained by Continental Stock Transfer & Trust Company, acting as trustee.
