Frequently asked questions
What is Clean Harbors Inc's revenue?

How profitable is CLH?
In its most recent fiscal year, CLH ran a gross margin of 29.51%, an operating margin of 11.17%, and a net margin of 6.48%. 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 CLH generate?
CLH produced $441.81M 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.
