The analyst's take on Corning Incorporated
Corning Incorporated has grown revenue from $9.39B to $16.41B over the last 10 fiscal years, compounding about 7.7% a year. The most recent year was up 13.4%, so growth is actually accelerating.
Net margin sits at 9.7%, up 6.2 points year over year on a 34.3% gross margin. It carries about $804.00M of total debt.
At today's valuation the market is pricing in roughly 27.4% annual free-cash-flow growth — versus the 12% 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 receivables growing faster than sales.
