Frequently asked questions
What is Westlake Chemical Corporation's revenue?
Westlake Chemical Corporation's trailing twelve-month revenue is $10.98B. Revenue is the top line the whole model builds on, and at this scale the question shifts from how fast it grows to whether margins hold as it compounds.
How profitable is WLK?
In its most recent fiscal year, WLK ran a gross margin of 2.59%, an operating margin of -14.13%, and a net margin of -13.50%. Margins this high mean most of each extra dollar of revenue drops through to profit, which is the signature of real pricing power.
How much free cash flow does WLK generate?
WLK produced $-530.00M in free cash flow in its most recent fiscal year. Free cash flow is what is left after running and reinvesting in the business, and it is the cash that actually funds buybacks, dividends, and a stronger balance sheet.
Is WLK's balance sheet healthy?
WLK holds $2.72B in cash and equivalents against $5.09B in long-term debt, on $8.79B of shareholder equity. That debt is best read against the cash flow the business throws off each year.
