Arthur J. Gallagher & Co. is an insurance broker that helps businesses find and buy insurance, and also handles their claims.
Arthur J. Gallagher & Co. is one of the world's biggest insurance brokers. But here's the twist: it doesn't actually pay out claims when something goes wrong. Instead, it's the middleman. When a business needs insurance — say a restaurant chain wants coverage in case a customer slips and sues, or a trucking company needs protection for its fleet — Gallagher's job is to shop around, find the right insurer, negotiate the price, and handle the paperwork. The insurer takes the risk. Gallagher takes a commission or a fee for arranging the deal. Think of it as a real estate agent, but for insurance: the agent doesn't own the house, they just connect buyer and seller and get paid for the match.
The company has two main pieces. The bigger one, by far, is insurance brokerage — roughly three-quarters of revenue — where Gallagher acts as the go-between for companies of all sizes, from small local firms to huge multinationals. The smaller piece is risk management, where Gallagher helps businesses control losses and handle claims more efficiently. Gallagher makes money in a few ways: commissions when a policy is sold, fees for advice and administration, and extra fees for specialty work like actuaries or employee benefits consulting. A big chunk of revenue is recurring — clients renew year after year — which makes the business steady and predictable. The company also grows by buying other smaller brokers, often dozens every year, and folding them into its network. That's a key driver: it uses its cash flow to keep acquiring, which adds new clients and commissions.
Gallagher is headquartered near Chicago, and it serves clients in over 130 countries. It's been around since 1927, started by Arthur James Gallagher, but today it's a global operation. The insurance broking industry is dominated by a few giants — Marsh, Aon, and Willis Towers Watson are the main rivals — and Gallagher is right up there with them. What makes Gallagher attractive is its mix of steady organic growth (clients renewing and premiums rising) plus a relentless acquisition machine. The company also pays a dividend and buys back shares, but its main use of cash is buying other brokers. That strategy has worked well: revenue has grown steadily, and the stock has been a long-term performer. In short, Gallagher doesn't bet on whether disasters happen — it just gets paid for helping others manage the risk.
