Two Things to Like:
1. Encouraging Short-Term Revenue Growth
We at StockStory place the most emphasis on long-term growth, but within industrials, a stretched historical view may miss cycles, industry trends, or a company capitalizing on catalysts such as a new contract win or a successful product line. Corning’s annualized revenue growth of 9.9% over the last two years is above its five-year trend, suggesting its demand recently accelerated. 
2. Outstanding Long-Term EPS Growth
Analyzing the long-term change in earnings per share (EPS) shows whether a company's incremental sales were profitable – for example, revenue could be inflated through excessive spending on advertising and promotions.
Corning’s EPS grew at 12.6% compounded annual growth rate over the last five years, higher than its 7.5% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.

One Reason to be Careful:
Previous Growth Initiatives Haven’t Impressed
Growth gives us insight into a company’s long-term potential, but how capital-efficient was that growth? A company’s ROIC explains this by showing how much operating profit it makes compared to the money it has raised (debt and equity).
Although Corning has shown solid fundamentals lately, it historically did a mediocre job investing in profitable growth initiatives. Its five-year average ROIC was 6.4%, somewhat low compared to the best industrials companies that consistently pump out 20%+.

Final Judgment
Corning’s merits more than compensate for its flaws, and with the recent surge, the stock trades at 41.5× forward P/E (or $137.25 per share). Is now the time to initiate a position? See for yourself in our in-depth research report, it’s free.
