Who Owns W. R. Berkley?

William R. Berkley founded the company in 1967 in Greenwich, Connecticut, fresh from Harvard Business School, with a thesis that specialist underwriters would beat generalists over time. The original firm, Berkley Dean & Company, merged with a small Connecticut insurer in 1970 to gain licenses, and the W. R. Berkley name was established.

The company listed on the New York Stock Exchange in 1973. Through the 1970s and 1980s it grew by adding specialty units rather than building one big underwriter, writing business in hard markets and retreating in soft ones. Acquisitions such as Nautilus Insurance Group and Carolina Casualty built the excess and surplus and commercial auto franchises that remain core units today. This cycle-sensitive approach to growth became a hallmark: capital flows to units whose markets offer adequate pricing and away from those that do not.

The 1990s and 2000s brought international expansion. The company built operations in the United Kingdom, Latin America, Continental Europe, and Australia, and established Berkley Syndicate 1967 at Lloyd's of London. Domestically it added professional liability, surety, program administration, and workers compensation specialists, assembling what became a portfolio of dozens of niche carriers.

That unit-by-unit approach had a second benefit: it let the company enter markets quickly. When a niche opened, Berkley could stand up a dedicated carrier with specialist staff rather than force the business through a generalist underwriting hierarchy. Several of today's larger units began as small startups funded by the holding company.

A generational leadership transition began in 2009, when W. Robert Berkley Jr. became president and chief operating officer, and he took the CEO role in 2015. Under him the company created new units organically, including the Berkley One high-net-worth personal lines insurer launched in 2017, rather than relying on acquisitions.

The hard commercial insurance market of the early 2020s powered record results. Net premiums written grew from $8.9 billion in 2021 to $12.7 billion in 2025, and fiscal 2025 set company records for revenue of $14.7 billion, pre-tax underwriting income of $1.2 billion, net investment income of $1.4 billion, and net income of $1.78 billion.

Through all of it, the brand never changed its basic proposition. W. R. Berkley sells specialist underwriting backed by a strong balance sheet, and it sells it to brokers rather than the public. Six decades on, that is still the entire strategy.
