Westlake free cash flow growth trends
Over the last five reported fiscal years, free cash flow declined from $772.0M to −$530.0M, a net decrease of $1.30B. Westlake's latest reported quarter, Q2 2026, generated $111.0M in free cash flow, an increase of $243.0M 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.
