Item 8.01 Other Events.

On May 13, 2024, GP-Act III Acquisition Corp. (the “Company”) consummated its initial public offering (the “IPO”) of 28,750,000 units (the “Units”), including the issuance of 3,750,000 units as a result of the underwriter’s exercise of its over-allotment option. Each Unit consists of one Class A ordinary share of the Company, par value $0.0001 per share (an “Ordinary Share”), and one-half of one redeemable warrant of the Company. Each whole warrant entitles the holder thereof to purchase one Ordinary Share for $11.50 per share, subject to adjustment. The Units were sold at a price of $10.00 per Unit, generating gross proceeds to the Company of $287,500,000.

Substantially concurrently with the closing of the IPO, the Company completed the private sale of an aggregate of 7,000,000 warrants (the “Private Placement Warrants”) at a purchase price of $1.00 per Private Placement Warrant, to (i) the GP-Act III Sponsor LLC, a Cayman Islands limited liability company (the “Sponsor”), and (ii) Cantor Fitzgerald & Co., generating aggregate gross proceeds to the Company of $7,000,000. The Private Placement Warrants are identical to the warrants sold as part of the Units in the IPO except that the Private Placement Warrants: (1) will not be redeemable by the Company; (2) may not (and the Ordinary Shares issuable upon exercise of the Private Placement Warrants may not), subject to certain limited exceptions, be transferred, assigned or sold until 30 days after the completion of the Company’s initial business combination; (3) may be exercised by the holders on a cashless basis; and (4) are entitled to registration rights (including in respect of the Ordinary Shares issuable upon exercise of the Private Placement Warrants).

A total of $287,500,000, comprised of proceeds from the IPO and the sale of the Private Placement Warrants, were placed in a U.S.-based trust account at J.P. Morgan Chase Bank, N.A., maintained by Continental Stock Transfer & Trust Company, acting as trustee. An audited balance sheet as of May 13, 2024 reflecting receipt of the proceeds upon consummation of the IPO and the sale of the Private Placement Warrants has been issued by the Company and is included as Exhibit 99.1 to this Current Report on Form 8-K.
