Evan Greenberg has been named to Barron’s 2026 Top CEOs list, recognized for building Chubb into the world’s leading property and casualty insurer through strategic leadership and disciplined underwriting that has consistently outpaced industry peers.
Greenberg engineered the landmark 2016 merger of ACE Limited, which he led as CEO, with The Chubb Corporation in a $28.3 billion transaction that created a powerhouse in global insurance. The combined company adopted the Chubb name and has since emerged as the industry’s most profitable operator.
Since the merger closed in January 2016, Chubb has consistently beaten its peers in profitability as measured by underwriting performance, according to Barron’s. This strength reflects the culture Greenberg has fostered, emphasizing disciplined risk selection and pricing discipline even as competitors have softened their rates.
The company’s 2025 financial results underscore this sustained performance. Chubb reported full-year net income of $10.31 billion, up 11.2% from the prior year, and achieved record core operating income of $9.95 billion. The insurer also posted a record property and casualty combined ratio of 81.5%, demonstrating superior underwriting profitability across its core business.
Greenberg’s tenure as CEO spans more than two decades. He was elected President and Chief Executive Officer of ACE in May 2004 and became Chairman of the Board in May 2007. At 71, he has stated he has no plans to retire, remaining focused on Chubb’s long-term strategy and competitive positioning.
Warren Buffett’s Berkshire Hathaway is Chubb’s largest shareholder, holding an 8% stake in the company, a sign of confidence in Greenberg’s stewardship. The insurance market has faced pricing pressure in recent months, with Greenberg publicly criticizing competitors for contributing to what he called a “dumb” downward pricing trend in property insurance. Chubb’s disciplined underwriting approach is expected to shield it better than peers from any margin erosion during soft market conditions.
