Does the December share price for Analog Devices, Inc. (NASDAQ:ADI) reflect what it's really worth? Today, we will estimate the stock's intrinsic value by taking the expected future cash flows and discounting them to today's value. The Discounted Cash Flow (DCF) model is the tool we will apply to do this. Models like these may appear beyond the comprehension of a lay person, but they're fairly easy to follow.
We would caution that there are many ways of valuing a company and, like the DCF, each technique has advantages and disadvantages in certain scenarios. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.
What's the estimated valuation?
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.
A DCF is all about the idea that a dollar in the future is less valuable than a dollar today, and so the sum of these future cash flows is then discounted to today's value:
10-year free cash flow (FCF) forecast
|Levered FCF ($, Millions)||US$2.17b||US$2.50b||US$2.69b||US$3.17b||US$3.46b||US$3.68b||US$3.86b||US$4.02b||US$4.16b||US$4.29b|
|Growth Rate Estimate Source||Analyst x8||Analyst x4||Analyst x2||Analyst x1||Analyst x1||Est @ 6.25%||Est @ 4.99%||Est @ 4.1%||Est @ 3.48%||Est @ 3.05%|
|Present Value ($, Millions) Discounted @ 8.4%||US$2.0k||US$2.1k||US$2.1k||US$2.3k||US$2.3k||US$2.3k||US$2.2k||US$2.1k||US$2.0k||US$1.9k|
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$21b
We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. 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 (2.0%) 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 8.4%.
Terminal Value (TV)= FCF2030 × (1 + g) ÷ (r – g) = US$4.3b× (1 + 2.0%) ÷ (8.4%– 2.0%) = US$68b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$68b÷ ( 1 + 8.4%)10= US$30b
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$52b. 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$142, the company appears around fair value at the time of writing. 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.
Now the most important inputs to a discounted cash flow are the discount rate, and of course, the actual cash flows. If you don't agree with these result, have a go at the calculation yourself and play with the assumptions. 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 Analog Devices 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 8.4%, which is based on a levered beta of 1.223. 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.
Although the valuation of a company is important, it is only one of many factors that you need to assess for a company. The DCF model is not a perfect stock valuation tool. Rather it should be seen as a guide to "what assumptions need to be true for this stock to be under/overvalued?" For instance, if the terminal value growth rate is adjusted slightly, it can dramatically alter the overall result. For Analog Devices, we've compiled three additional factors you should consider:
