What does it do?
Arthur J. Gallagher is one of the world's largest insurance brokers — think of them as the middleman who helps businesses find the right insurance coverage. If a hospital needs malpractice insurance or a shipping company needs cargo coverage, Gallagher shops around dozens of insurers to find the best deal and takes a fee for doing so. They also help companies manage risks and handle insurance claims when things go wrong. With offices in over 60 countries, they work with everyone from small local businesses to massive global corporations.
Insurance brokerage is a rare business that grows naturally when the economy grows — more businesses mean more policies, and rising insurance premiums mean bigger commissions without Gallagher having to do much extra work. The company has been on an aggressive acquisition spree, buying up smaller brokers around the world, which is a proven playbook that has made rivals like Marsh and Aon into giants. In an uncertain economic environment, insurance is one of the last things businesses cut, making Gallagher's revenue unusually stable.
How does it make money?
Gallagher makes money primarily by charging commissions and fees every time they place an insurance policy — typically a percentage of the premium paid. Revenue jumped from $11.4B to $13.8B in a single year, a 21% increase driven by acquisitions and rising insurance premiums across the market. Their Brokerage segment is the core engine, while a smaller Risk Management segment earns fees for handling claims on behalf of companies that self-insure. Net income came in at $1.5B, showing the business converts a meaningful slice of that revenue into profit.
Why do investors care?
The growth story here is simple: Gallagher buys smaller, privately-owned insurance brokers, plugs them into its global platform, and squeezes out more value — they call this the 'Gallagher Way.' There are thousands of small brokers globally still ripe for acquisition, giving the company a long runway of deal-making. Investors also love that insurance premiums have been rising sharply in recent years due to climate-related claims and inflation, which automatically boosts Gallagher's commission income. For the thesis to work, the acquisitions need to keep coming at reasonable prices and insurance market conditions need to stay firm.
