Item 8.01 Other Events.

As previously reported, on July 13, 2021, Acropolis Infrastructure Acquisition Corp. (the “Company”) consummated its initial public offering (the “IPO”) of 30,000,000 units (the “Units”). Each Unit consists of one share of the Company’s Class A common stock, par value $0.0001 per share (the “Class A Common Stock”), and one-third of one warrant of the Company (the “Warrants”), each whole warrant entitling the holder thereof to purchase one whole share of Class A Common Stock at a price of $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 $300,000,000. The Company granted the underwriters a 30-day over-allotment option to purchase up to an additional 4,500,000 Units (“Over-Allotment Units”).

As previously reported, simultaneously with the closing of the IPO, the Company completed the private sale (the “Private Placement”) of an aggregate of 5,235,000 warrants (the “Private Placement Warrants”) at a purchase price of $1.50 per Private Placement Warrant, to the Company’s sponsor, Acropolis Infrastructure Acquisition Sponsor, L.P. (the “Sponsor”), generating gross proceeds to the Company of $7,852,500.

On August 3, 2021, the Company consummated the sale of 4,500,000 Over-Allotment Units pursuant to the underwriters’ exercise of their over-allotment option. Such Over-Allotment Units were sold at $10.00 per Unit, generating gross proceeds of $45,000,000. Substantially concurrently with the closing of the sale of the Over-Allotment Units, the Company consummated the private sale of an additional 600,000 Private Placement Warrants at a purchase price of $1.50 per Private Placement Warrant to the Sponsor, generating gross proceeds of $900,000.  Following the closing of the over-allotment option and sale of additional Private Placement Warrants (together, the “Over-Allotment Closing”), a total of $345,000,000, including approximately $12,075,000 of the underwriters’ deferred discount, was held in a U.S.-based trust account with Continental Stock Transfer & Trust Company acting as trustee.

An audited balance sheet as of July 13, 2021, reflecting receipt of the proceeds upon consummation of the IPO and the Private Placement Warrants has been issued by the Company and previously filed as Exhibit 99.1 to a Current Report on Form 8-K on July 19, 2021.
