Global reinsurer MS Reinsurance announced a net profit after tax of $415 million for the year ended 2025, up from $346 million in 2024. The profit boost came from stronger underwriting and investment results, including a $307 million investment gain and a 4.7% investment return despite market volatility.

The company’s combined ratio improved to 87.4% in 2025 from 88.7% the previous year, and gross written premiums rose to $3.9 billion from $3.6 billion. CEO Robert Wiest highlighted a strategic shift toward de‑risking, portfolio rebalancing, and stronger governance.

These upgrades reflect the company’s increased strategic importance to its parent, Mitsui Sumitomo Insurance.
