Each Unit consists of one Class A ordinary share, par value $0.0001 per share (“Class A Ordinary Shares”), and one-half of one redeemable warrant (each, a “Warrant”), each whole Warrant entitling the holder thereof to purchase one Class A Ordinary Share at an exercise price of $11.50 per share, subject to adjustment, pursuant to the Company’s registration statements on Form S-1 (File Nos. 333-284565 and 333-286920). The Units were sold at an offering price of $10.00 per Unit, generating gross proceeds to the Company of $276,000,000.

As previously reported, on May 5, 2025, simultaneously with the consummation of the Offering, the Company consummated the private placement of 4,400,000 warrants to CGC III Sponsor LLC and 2,400,000 warrants to Cantor Fitzgerald & Co. (collectively, the “Private Placement Warrants”) at a price of $1.00 per Private Placement Warrant, generating gross proceeds to the Company of $6,800,000 (the “Private Placement”).

A total of $276,000,000 ($10.00 per Unit) of the net proceeds from the Offering and the Private Placement, which amount includes $13,140,000 in deferred underwriting commissions, was placed in a trust account established for the benefit of the Company’s public shareholders, with Continental Stock Transfer & Trust Company acting as trustee.
