Frequently asked questions
What is Zscaler Inc's revenue?
Zscaler Inc's trailing twelve-month revenue is $3.35B, and consensus projects about $6.98B by 2030. 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 ZS?
In its most recent fiscal year, ZS ran a gross margin of 76.80%, an operating margin of -3.98%, and a net margin of -1.88%. 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 ZS generate?
ZS produced $852.35M 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 ZS's balance sheet healthy?
ZS holds $928.35M in cash and equivalents against $1.70B in long-term debt, on $2.60B of shareholder equity. That debt is best read against the cash flow the business throws off each year.
