Ategrity Specialty Insurance Taps New CFO, Announces Record Financial Performance

SCOTTSDALE, Ariz.–(BUSINESS WIRE)–A twenty-five-year veteran of financial services and recent CFO within Global Atlantic insurance company, David Rosenzweig has been appointed Chief Financial Officer of Ategrity Specialty Holdings and its subsidiaries. Rosenzweig, who has been a consultant with the company since last year, now joins the leadership team full-time as Ategrity posts a record 17% annualized return on equity for Q4 2021. Ategrity launched in 2018, focusing on the excess and surplus (E&S) lines market, and in 2021 received $75 million in capital from Sequentis Financial LLC.
