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.
