AmTrust expands its E&S division with new product lines and a major MGA spin-off partnership.

AmTrust Financial Services has expanded its Excess and Surplus division with new product lines in property, environmental, and builders risk, consolidating its primary, excess, and environmental offerings into a new brokerage casualty group. The move, part of a broader strategy to strengthen its specialty insurance platform, includes hiring senior industry leaders and a partnership with Blackstone Credit & Insurance to spin off seven MGAs into a new independent company by year-end. AmTrust will retain underwriting capacity for those MGAs under a 10-year agreement, positioning itself to better serve clients amid growing demand in the E&S market driven by economic uncertainty and rising claims.
