Significance 4/10

Director Zimmer Stuart J. bought 11,130 shares over two days (Sept 29–30) at $19.41 blended average amid 27.6% decline from 52-week high

Stuart J. Zimmer, a director at Ategrity Specialty Insurance, made two separate open-market purchases totaling 11,130 shares for $216,088.73 on 2025-09-29 and 2025-09-30, with a blended average price of $19.41. The stock is currently trading at $17.88, down 27.6% from its 52-week high of $24.68 and -21.0% over the prior 30 days, reflecting recent weakness in the equity. His prior trades at this ticker (buys on 2025-09-26, 2025-09-25, and 2025-08-13) show a pattern of acquisition activity in the same period, though only the 2025-08-13 purchase has measurable outcomes (30-day return +7.8%). The cross-ticker track record shows 3 prior open-market buys with an average 30-day return of +7.8%, but this provides limited precision on timing expectations at ASIC specifically.

Significance 4/10

Director Zimmer Stuart J. purchased 9,920 shares at blended $19.45 on ASIC amid -22.2% decline from 52-week high

Director Stuart J. Zimmer executed 2 separate purchases totaling 9,920 shares for $192,901.77 at a blended average price of $19.45 on consecutive dates (2025-09-25 and 2025-09-26), increasing his holdings to 38,527,411 shares post-transaction. The timing coincides with material price weakness: the stock is trading $19.19 (current price), down 22.2% from its 52-week high of $24.68 and down 15.2% over the prior 30 days. While the company shows fundamentally solid metrics with revenue of $101,780,000.00 and net income of $17,622,000.00, the purchase at depressed levels represents a modest addition (0.0% net change vs. pre-transaction holdings) rather than a major commitment. The director's prior same-ticker buy on 2025-08-13 generated a positive 30d return of 7.8%, but outcomes at the 90-day mark remain incomplete, limiting inference about timing accuracy at this specific ticker.

5,051 shares
$98,426
Significance 3/10

Director Zimmer Stuart J. purchased 5,051 shares of ASIC at $19.49 on 2025-08-13 for $98,425.81.

Director Zimmer Stuart J. acquired 5,051 shares at $19.49, increasing his holdings from 38,512,440 to 38,517,491 shares. The transaction represents a minimal 0.0% increase to his existing position. The purchase price of $19.49 sits near the lower end of the 52-week range of $18.68–$24.68, roughly 9% below the current price of $21.47. Against the backdrop of quarterly revenue of $101,780,000 and net income of $17,622,000, the company maintains a market cap of $1,031,991,490.78. The modest share count addition to an already substantial holding warrants standard disclosure review but does not yet signal a material shift in insider positioning.
