"% of total stake" is the shares in an event against all the vested shares the person held that day, across every share class and holding entity, after that day's vesting. "n/a" means the person's holdings are not confirmed, or the row is a purchase. "Holdings record incomplete" means more shares were sold than the filings show the person held that day, so a percentage would be wrong.

Outside holders, reported separately

James Sowell sold $50.3M in the past 12 months. Large shareholders and the funds or companies that board members represent are not part of management, so they are left out of the figures above.

Common questions

Is the American Integrity Insurance Group, Inc. CEO selling stock?

Yes. Robert Ritchie sold 1.23M shares ($27.6M) in the past 12 months, 63% of it under a trading plan disclosed in the filings.

No plan disclosed · $13.4M

Sales with no 10b5-1 plan and no tax reference in the filing. $10.2M of it is Robert Ritchie. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Robert Ritchie, Nov 21, 2025

5,689 shares ($112K) were withheld by the company for taxes, which isn't a market sale.

Sources and methodology67 filings on record, 47 filed in the 12-month period, and how we read them

All 67 Forms 3, 4 and 5 on record for American Integrity Insurance Group, Inc. (SEC CIK 2007587), filed from May 7, 2025 to Oct 15, 2026; 47 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 16, 2026. Prices are the ones reported in each filing, often weighted averages.

Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.

Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
