Harbour Island Acquisition Corp. I is seeking to raise $100 million (up to $115 million with over-allotment) through an IPO of units priced at $10.00 each, with proceeds placed in a trust account. The company has 24 months from the closing date to complete an initial business combination, with potential for extension via shareholder approval. If not completed, public shares will be redeemed at trust account value. No public market exists for its securities, and it intends to list units on Nasdaq under 'HRIAU' after separation of Class A shares and warrants. The company is an emerging growth company with reduced reporting requirements, and investing involves significant risks including redemption terms, conflicts of interest, and uncertainty around business combination success.
