AM Best Market Segment Report On Reinsurers
AM Best reports that a group of U.S. and Bermuda reinsurers maintained underwriting profitability in 2025, with a 16.8% net return on equity, despite slower premium growth. The composite includes seven companies, such as Arch Capital and Everest Group. Profitability was supported by higher investment income, but growth slowed to less than 1.0% due to market softening. AM Best expects muted growth in 2026 amid declining rates in property and casualty lines.
