About the metric
What capital expenditures (CapEx) mean
Capital expenditures, commonly called CapEx, are cash investments in long-lived assets such as property, plants, equipment, infrastructure, and productive software. CapEx can support future growth or maintain existing operations, but it reduces current-period free cash flow.
Calculation and source
SEC-reported capital expenditures
TickerStat standardizes cash payments for property, plant, equipment, and other productive assets reported in company SEC filings. When a filer reports separate qualifying CapEx components instead of a total, those components are combined for the same fiscal period. Fiscal periods can differ from calendar years, so exact period-end dates are included.
