Aon free cash flow growth trends
Over the last five reported fiscal years, free cash flow grew from $2.64B to $3.22B, a compound annual growth rate of 4.02%. Aon's latest reported quarter, Q2 2026, generated $483.0M in free cash flow, a decrease of 34.02% year over year.
About the metric
What free cash flow means
Free cash flow is the cash a company generates from operations after capital expenditures. Positive FCF can fund dividends, buybacks, debt repayment, or reinvestment; negative FCF means capital spending exceeded operating cash flow for that period.
Calculation and source
How free cash flow is calculated
TickerStat calculates free cash flow as SEC-reported operating cash flow minus capital expenditures. FCF margin equals free cash flow divided by revenue. Fiscal periods can differ from calendar years, so the tables include exact period-end dates.
