The bull case uses $17,500 million, $19,000 million and $20,700 million, with margins of 10.2%, 10.8% and 11.3%. The bear reflects weaker new business, producer departures and delayed integration; the bull reflects retention, faster synergies and better cash conversion.

How much cash does Gallagher really make?

Cash conversion asks how much reported profit becomes cash from operations. Gallagher’s “real free cash flow” starts with operating cash, subtracts capital spending and then subtracts stock-based pay. In 2025, free cash flow was $1,785 million and real free cash flow was $1,736 million. Real free cash flow represented 12.5% of revenue in 2025, compared with 20.8% in 2024.

What this means. Stock pay uses no cash today, but it gives employees part of the company, so we subtract its value to show what is truly left for shareholders.

What does an investor pay for Gallagher today?

The free-cash-flow yield is modest against the 5.09% US 10-year Treasury yield on October 16, 2026. Dividends are also a small part of the return, while price to book is an imperfect guide for a serial acquirer whose balance sheet contains goodwill and acquired customer relationships.
