Corning is an interesting stock to consider for your portfolio. Below are 4 reasons that make Corning a buy and a few items to keep an eye when evaluating the company.

1. Stock is cheap

The stock is cheap. Let's look at a range of measurements to compare the stock price (around $14) against intrinsic value:

  • Book value per share is $14. The company is currently trading at book value.
  • I estimate reproduction value of Corning to be more than $16. At current prices it is trading below reproduction value.
  • Discounted cash flow analysis (growth rate of 5%, discount rate of 10%, based on average owner's earnings over the last 5 years) gives an intrinsic value of $18.
  • Average EPS of the last 5 years is $2.06. This implies the company is trading with a P/E of 7 based on 5 year-average historical EPS.
  • Forward P/E is 8 based on analysis consensus of 2012 EPS.

2. Solid balance sheet

The balance sheet is very solid: Total debt of $2.3 billion versus $6.4 billion in cash and more than $20 billion in equity. The debt-to-equity ratio is 10%. Over the last 5 years the company has invested on average 60% of operating earnings to cover expansion of manufacturing capabilities. Capital expenditures are expected to slow down in the coming years. This will increase free cash flow and allow the company to return more cash to shareholders.

3. Market Leader in key segments

Corning is the market leader in the display technology and telecommunications segment. Corning, including Samsung Corning Precision, is the largest worldwide producer of glass substrates for active matrix LCD displays. Its proprietary fusion manufacturing process produces glass that is larger, thinner and lighter, with exceptional surface quality and without heavy metals. In the telecommunications segment the company is the largest producer of optical fiber and cable products.

The market for phones and tablet computing is growing rapidly. This will drive demand for sophisticated glass products in the Specialty material division, like Corning's Gorilla Glass. Sales in this division have almost doubled in 2011 compared with 2010. The long-term trend toward phones and tablets with touch screens will drive growth in the coming years.

4. Technology Leader

Corning invests around 9% of revenue in research and development. Inventions by members of Corning's research and engineering staff have been important to the company's growth. At the end of 2010, Corning and its wholly owned subsidiaries owned more than 4,300 unexpired patents in various countries of which about 2,300 were U.S. patents. Worldwide, Corning has more than 6,750 patent applications in process, with about 1,900 in process in the U.S. The patents not only help the company to innovate and stay ahead of the competition, it also is a source of royalty income ($51 million in Q3, 2011).

There are a few risks investors should keep an eye on. The Q3 2011 earnings were slightly disappointing due to price declines, lower equity earnings and a decrease in royalty income. Price erosion is a risk that might further squeeze profit margins. The company products are highly correlated with consumer spending. A slowdown or recession will significantly impact sales. The company has 10 customers that account for 55% of the revenue. Loss of 1 or 2 of these customers will have a material impact on the results.
