The analyst's take on Insteel Industries Inc.
Insteel Industries Inc. has grown revenue from $418.55M to $647.71M over the last 10 fiscal years, compounding about 6.5% a year. The most recent year was up 22.4%, so growth is actually accelerating.

At today's valuation the market is pricing in roughly 12.5% annual free-cash-flow growth — versus the -17.3% it actually delivered over the last five years, so the price already assumes a step-up from the recent record. The one thing worth a second look in the filings is inventory building faster than sales.
