Frequently asked questions
What is Advanced Drainage Systems Inc's revenue?
Advanced Drainage Systems Inc's trailing twelve-month revenue is $3.05B. 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 WMS?
In its most recent fiscal year, WMS ran a gross margin of 36.31%, an operating margin of 22.51%, and a net margin of 13.98%. 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 WMS generate?
WMS produced $569.29M 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 WMS's balance sheet healthy?
WMS holds $223.01M in cash and equivalents against $1.61B in long-term debt, on $1.93B of shareholder equity. That debt is best read against the cash flow the business throws off each year.
