In this article we are going to estimate the intrinsic value of Silicon Motion Technology Corporation (NASDAQ:SIMO) by estimating the company’s future cash flows and discounting them to their present value. The Discounted Cash Flow (DCF) model is the tool we will apply to do this. Before you think you won’t be able to understand it, just read on! It’s actually much less complex than you’d imagine.
Remember though, that there are many ways to estimate a company’s value, and a DCF is just one method. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.
We use what is known as a 2-stage model, which simply means we have two different periods of growth rates for the company’s cash flows. Generally the first stage is higher growth, and the second stage is a lower growth phase. To start off with, we need to estimate 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$81.1m||US$112.0m||US$119.3m||US$125.6m||US$131.0m||US$135.8m||US$140.2m||US$144.4m||US$148.3m||US$152.1m|
|Growth Rate Estimate Source||Analyst x4||Analyst x1||Est @ 6.52%||Est @ 5.23%||Est @ 4.33%||Est @ 3.7%||Est @ 3.25%||Est @ 2.94%||Est @ 2.73%||Est @ 2.57%|
|Present Value ($, Millions) Discounted @ 10%||US$73.6||US$92.3||US$89.3||US$85.3||US$80.8||US$76.0||US$71.3||US$66.6||US$62.1||US$57.8|
(“Est” = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$755m
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 (2.2%) 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 10%.
Terminal Value (TV)= FCF2030 × (1 + g) ÷ (r – g) = US$152m× (1 + 2.2%) ÷ (10%– 2.2%) = US$2.0b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$2.0b÷ ( 1 + 10%)10= US$746m
The total value is the sum of cash flows for the next ten years plus the discounted terminal value, which results in the Total Equity Value, which in this case is US$1.5b. The last step is to then divide the equity value by the number of shares outstanding. Relative to the current share price of US$39.7, the company appears about fair value at a 7.0% discount to where the stock price trades currently. Remember though, that this is just an approximate valuation, and like any complex formula – garbage in, garbage out.
The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the 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 Silicon Motion Technology 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 10%, which is based on a levered beta of 1.114. 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 shouldn’t be the only metric you look at when researching 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 example, changes in the company’s cost of equity or the risk free rate can significantly impact the valuation.
