Frequently asked questions
What is Westlake Chemical Partners LP's revenue?

How profitable is WLKP?
In its most recent fiscal year, WLKP ran a gross margin of 29.81%, an operating margin of 27.39%, and a net margin of 25.59%. 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 WLKP generate?
WLKP produced $201.65M 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.
