The analyst's take on Zscaler, Inc.
Zscaler, Inc. has grown revenue from $80.33M to $2.67B over the last 10 fiscal years, compounding about 44% a year. The most recent year was up 23.3%, so growth has cooled from its longer-run pace.
Net margin sits at -1.6%, up 1.1 points year over year on a 76.9% gross margin. It carries about $1.70B of total debt.
At today's valuation the market is pricing in roughly 11.9% annual free-cash-flow growth — versus the 82.1% it actually delivered over the last five years, so the price is arguably undemanding against what it has already proven. The one thing worth a second look in the filings is share count rising (dilution).
