The analyst's take on Diodes Incorporated
Diodes Incorporated has grown revenue from $942.16M to $1.48B over the last 10 fiscal years, compounding about 3.8% a year. The most recent year was up 13%, so growth is actually accelerating.
Net margin sits at 4.5%, up 1.1 points year over year on a 31.2% gross margin. It carries about $25.67M of total debt.
At today's valuation the market is pricing in roughly 14.8% annual free-cash-flow growth — versus the 4.2% 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 net margin shrinking.
