Item 8.01. Other Events.

As previously disclosed on a Current Report on Form 8-K dated July 23, 2021 (the “Current Report”), on July 19, 2021, the Company consummated its initial public offering (the “IPO”) of 15,000,000 units (the “Units”). Each Unit consists of one share of common stock, $0.0001 par value (“Common Stock”), one right entitling the holder thereof to receive one-twentieth (1/20) of one share of Common Stock upon the consummation of an initial business combination, and one-half of one warrant entitling the holder thereof to purchase one share of Common Stock at a price of $11.50 per whole share. The Units were sold at an offering price of $10.00 per Unit, generating gross proceeds of $150,000,000.

As previously disclosed in the Current Report, simultaneously with the closing of the IPO, the Company consummated the private placement (the “Private Placement”) with initial stockholders of the Company of 6,500,000 warrants (the “Private Warrants”), generating total proceeds of $6,500,000. The Company granted the underwriters a 45-day option to purchase up to 2,250,000 additional Units to cover over-allotments, if any.

On July 26, 2021, the underwriters fully exercised the over-allotment option and purchased an additional 2,250,000 Units (the “Over-Allotment Units”), generating gross proceeds of $22,500,000 on June 28, 2021. Simultaneously with the sale of Over-Allotment Units, the Company consummated a private sale of an additional 675,000 Private Warrants at a purchase price of $10.00 per Private Warrant, generating gross proceeds of $675,000. 

As of July 28, 2021, a total of $174,225,000 of the net proceeds from the IPO and the Private Placement were deposited in a trust account established for the benefit of the Company’s public stockholders.

An unaudited balance sheet as of July 28, 2021 reflecting receipt of the proceeds upon consummation of the IPO and the Private Placement has been issued by the Company and is included as Exhibit 99.1 to this Current Report on Form 8-K.
