Equity Ownership and Disclosure Analyst

Large shareholder-director sells shares in an underwritten offering via underwriters’ option, modestly reducing indirect stake while retaining a significant position.

The filing shows a sale of 295,037 shares of Common Stock of American Integrity Insurance Group, Inc. on 12/05/2025 at a net price of $19.00 per share. The sale occurred through the exercise of the underwriters’ option in an underwritten public offering, meaning the shares were part of a structured, marketed transaction rather than open-market selling. After this transaction, the reporting persons report beneficial ownership of 4,473,824 shares, held indirectly.

The shares are held by Sowell Investments Holding Co., LLC, with James E. Sowell as sole manager, and the form is jointly filed by both. The reporting persons emphasize that they disclaim beneficial ownership beyond their economic interest and also disclaim being part of any “group” under Sections 13(d) or 13(g). This language signals careful management of reporting status and control characterizations, which can affect regulatory thresholds and future filing obligations.

The key point to watch is that a director associated with a large indirect holding participated in the public offering via the underwriters’ option, slightly lowering the reported indirect holdings to 4,473,824 shares as of 12/05/2025. Future Form 4 or Schedule 13 filings, if any, will show whether this transaction is isolated or part of a broader pattern of stake changes over the coming quarters.
