The analyst's take on Quanex Building Products Corporation
Quanex Building Products Corporation has grown revenue from $928.18M to $1.84B over the last 10 fiscal years, compounding about 16.6% a year. The most recent year was up 43.8%, so growth is actually accelerating.
Net margin sits at -13.6%, down 16.2 points year over year on a 27.2% gross margin.
At today's valuation the market is pricing in roughly -6.6% annual free-cash-flow growth — versus the 6.4% 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).
