Ategrity Specialty Insurance Company Holdings
A specialty insurance company in the excess and surplus market, Ategrity writes property and casualty coverage for small and mid-sized businesses that mainstream insurers often turn away, selling through a network of wholesale agents and brokers. It was founded in 2017 by Stuart Zimmer and began operations the following year. The name blends "agility" and "integrity," and the company calls its data-driven approach to underwriting "productionized underwriting."

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 5 years: +140.1K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
