Gallagher is a global insurance broker that intermediates hard-to-place policies for corporations and individuals, earning a commission on every premium placed. Brokerage generates the overwhelming majority of revenue, with Risk Management a smaller consultative layer; a substantial share of revenue growth is fueled by bolt-on M&A.
Gallagher earns a fixed commission percentage on every premium it places, so profit scales linearly with the premium book; the compounding loop is buy a regional broker, add their recurring commission stream, and redeploy that cash to fund the next deal.
