Aon expands war risk insurance as peers report strong Q1. Aon is deepening its support for Ukraine war risk insurance, a move that highlights the company's role in complex global risk management. This development comes as rival Marsh McLennan reported better-than-expected first-quarter results, intensifying competition within the insurance brokerage sector. With Aon's stock trading near its 52-week high, investors are watching how these operational updates and peer performance will shape upcoming earnings expectations.
