RenRe trims property book as underwriting result offsets losses in casualty and specialty segment

RenaissanceRe Holdings Ltd. reported an underwriting income of $426.1 million in Q3 2026, primarily driven by a gain in its property segment which counteracted losses in casualty and specialty. Despite strong contributions from underwriting, fee, and investment income, the company recorded a net loss of $161.4 million due to significant mark-to-market losses on investments. RenRe's gross premiums written decreased across both property and casualty/specialty segments, while its combined ratio rose.
