About
Brown & Brown, Inc. is a Daytona Beach, Florida-based insurance brokerage and risk management company — publicly traded on the New York Stock Exchange (NYSE: BRO) as an S&P 500 Financials component — providing insurance brokerage, risk management consulting, and third-party claims administration services to businesses and individuals across the United States, Canada, the UK, Ireland, and Bermuda through approximately 16,000 employees at 500+ offices. In fiscal year 2024, Brown & Brown reported revenues of $4.5 billion (+12% organic growth) — continuing its 30-year track record of consistent organic and acquisition-driven revenue growth that has made Brown & Brown one of the fastest-growing large insurance brokers in the US, growing from $1B revenue in 2015 to $4.5B in 2024 through organic growth compounding and disciplined acquisition integration. CEO Powell Brown (son of founder Hyatt Brown, representing the family's generational leadership of the company) leads Brown & Brown's distinctive "decentralized" operating model where each acquired insurance agency retains its local brand identity, leadership team, and community relationships while benefiting from Brown & Brown's national carrier relationships, compliance infrastructure, shared technology, and capital for further acquisition. Brown & Brown's four business segments — Retail (local commercial insurance for small-to-midsize businesses), National Programs (specialty program insurance distributed through managing general agents for specific industries — veterinarians, dentists, pest control, construction), Wholesale Brokerage (surplus lines excess and specialty placement for non-admitted risks), and Services (third-party claims administration) — provide diversified revenue across insurance distribution channels that smooth individual market cycle volatility.
