Today we will run through one way of estimating the intrinsic value of Select Energy Services, Inc. (NYSE:WTTR) by taking the foreast future cash flows of the company and discounting them back to today's value. I will be using the Discounted Cash Flow (DCF) model. It may sound complicated, but actually it is quite simple!
Companies can be valued in a lot of ways, so we would point out that a DCF is not perfect for every situation. 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.
Step by step through the calculation
We're using the 2-stage growth model, which simply means we take in account two stages of company's growth. In the initial period the company may have a higher growth rate and the second stage is usually assumed to have a stable growth rate. 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) estimate
|Levered FCF ($, Millions)||$87.1m||$98.6m||$108.6m||$117.1m||$124.5m||$131.0m||$136.9m||$142.3m||$147.5m||$152.4m|
|Growth Rate Estimate Source||Analyst x8||Est @ 13.2%||Est @ 10.06%||Est @ 7.86%||Est @ 6.32%||Est @ 5.24%||Est @ 4.49%||Est @ 3.96%||Est @ 3.59%||Est @ 3.33%|
|Present Value ($, Millions) Discounted @ 9.15%||$79.8||$82.8||$83.5||$82.5||$80.4||$77.5||$74.2||$70.6||$67.0||$63.5|
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF)= $761.8m
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 10-year government bond rate (2.7%) 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 9.2%.
Terminal Value (TV) = FCF2029 × (1 + g) ÷ (r – g) = US$152m × (1 + 2.7%) ÷ (9.2% – 2.7%) = US$2.4b
Present Value of Terminal Value (PVTV) = TV / (1 + r)10 = $US$2.4b ÷ ( 1 + 9.2%)10 = $1.02b
The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is $1.78b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. This results in an intrinsic value estimate of $16.73. Relative to the current share price of $8.61, the company appears quite good value at a 49% 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.
Now the most important inputs to a discounted cash flow are the discount rate, and of course, the actual cash flows. Part of investing is coming up with your own evaluation of a company's future performance, so try the calculation yourself and check your own 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 Select Energy Services 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 9.2%, which is based on a levered beta of 1.078. 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?" If a company grows at a different rate, or if its cost of equity or risk free rate changes sharply, the output can look very different. What is the reason for the share price to differ from the intrinsic value? For Select Energy Services, I've put together three pertinent aspects you should look at:
