American Integrity Insurance Group, Inc.

Unregistered Sales of Equity Securities

On May 7, 2025, in connection with our IPO, we issued 417,400 shares of Common Stock in connection with grants of restricted stock outside of our long-term incentive plan to certain of our officers and employees, after giving effect to the withholding of approximately 234,587 shares of Common Stock to satisfy the estimated tax withholding and remittance obligations. The offers, sales, and issuances of the securities were deemed to be exempt from registration under Rule 506 promulgated under the Securities Act, or under Section 4(a)(2) of the Securities Act as a transaction by an issuer not involving a public offering.

Use of Proceeds

On May 9, 2025, we completed our IPO, and all shares of Common Stock sold were registered pursuant to a registration statement on Form S-1 (File No. 333-286524), as amended, declared effective by the SEC on May 7, 2025. We received net proceeds of approximately $82 million, after (i) deducting underwriting discounts and commissions totaling $7.0 million as well as $4.2 million of other expenses related to the offering, (ii) using approximately $3.8 million of the proceeds from the offering to satisfy tax withholding and remittance obligations related to the net settlement of shares of restricted stock issued in connection with the IPO and (iii) using $3.0 million of the proceeds of the offering to terminate the management services agreement by and between James Sowell Company, L.P. and AIIG. Pending their further use, the net proceeds from our IPO have been invested in investment grade instruments and there have been no material change in the expected use of the net proceeds from our IPO as described in our prospectus dated May 7, 2025 filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended, on May 8, 2025.
