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 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.
