In this article we are going to estimate the intrinsic value of Corning Incorporated (NYSE:GLW) by taking the forecast future cash flows of the company and discounting them back to today's value. We will use the Discounted Cash Flow (DCF) model on this occasion. Believe it or not, it's not too difficult to follow, as you'll see from our example!
We generally believe that a company's value is the present value of all of the cash it will generate in the future. However, a DCF is just one valuation metric among many, and it is not without flaws. If you want to learn more about discounted cash flow, the rationale behind this calculation can be read in detail in the Simply Wall St analysis model.
We are going to use a two-stage DCF model, which, as the name states, takes into account two stages of growth. The first stage is generally a higher growth period which levels off heading towards the terminal value, captured in the second 'steady growth' period. To begin with, we have to get estimates of the next ten years of cash flows. Where possible we use analyst estimates, but when these aren't available we extrapolate the previous free cash flow (FCF) from the last estimate or reported value. We assume companies with shrinking free cash flow will slow their rate of shrinkage, and that companies with growing free cash flow will see their growth rate slow, over this period. We do this to reflect that growth tends to slow more in the early years than it does in later years.
Generally we assume that a dollar today is more valuable than a dollar in the future, so we need to discount the sum of these future cash flows to arrive at a present value estimate:
10-year free cash flow (FCF) estimate
|Levered FCF ($, Millions)||US$2.07b||US$2.27b||US$2.39b||US$2.68b||US$2.86b||US$3.00b||US$3.13b||US$3.23b||US$3.33b||US$3.42b|
|Growth Rate Estimate Source||Analyst x6||Analyst x2||Analyst x2||Analyst x1||Est @ 6.43%||Est @ 5.08%||Est @ 4.14%||Est @ 3.48%||Est @ 3.02%||Est @ 2.69%|
|Present Value ($, Millions) Discounted @ 7.1%||US$1.9k||US$2.0k||US$1.9k||US$2.0k||US$2.0k||US$2.0k||US$1.9k||US$1.9k||US$1.8k||US$1.7k|
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$19b
The second stage is also known as Terminal Value, this is the business's cash flow after the first stage. For a number of reasons a very conservative growth rate is used that cannot exceed that of a country's GDP growth. In this case we have used the 5-year average of the 10-year government bond yield (1.9%) to estimate future growth. In the same way as with the 10-year 'growth' period, we discount future cash flows to today's value, using a cost of equity of 7.1%.
Terminal Value (TV)= FCF2032 × (1 + g) ÷ (r – g) = US$3.4b× (1 + 1.9%) ÷ (7.1%– 1.9%) = US$67b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$67b÷ ( 1 + 7.1%)10= US$34b
The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is US$53b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. Relative to the current share price of US$34.4, the company appears quite undervalued at a 45% discount to where the stock price trades currently. Valuations are imprecise instruments though, rather like a telescope - move a few degrees and end up in a different galaxy. Do keep this in mind.
We would point out that the most important inputs to a discounted cash flow are the discount rate and of course the actual cash flows. You don't have to agree with these inputs, I recommend redoing the calculations yourself and playing with them. The DCF also does not consider the possible cyclicality of an industry, or a company's future capital requirements, so it does not give a full picture of a company's potential performance. Given that we are looking at Corning as potential shareholders, the cost of equity is used as the discount rate, rather than the cost of capital (or weighted average cost of capital, WACC) which accounts for debt. In this calculation we've used 7.1%, which is based on a levered beta of 1.225. Beta is a measure of a stock's volatility, compared to the market as a whole. We get our beta from the industry average beta of globally comparable companies, with an imposed limit between 0.8 and 2.0, which is a reasonable range for a stable business.
Whilst important, the DCF calculation ideally won't be the sole piece of analysis you scrutinize for a company. DCF models are not the be-all and end-all of investment valuation. Rather it should be seen as a guide to "what assumptions need to be true for this stock to be under/overvalued?" For example, changes in the company's cost of equity or the risk free rate can significantly impact the valuation. Can we work out why the company is trading at a discount to intrinsic value?
