In this article we are going to estimate the intrinsic value of Waste Management, Inc. (NYSE:WM) by taking the expected future cash flows and discounting them to their present value. I will be using the Discounted Cash Flow (DCF) model. It may sound complicated, but actually it is quite simple!
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.
Crunching the numbers
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 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, 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)||US$2.11b||US$2.27b||US$2.44b||US$2.63b||US$2.78b||US$2.89b||US$2.99b||US$3.08b||US$3.15b||US$3.23b|
|Growth Rate Estimate Source||Analyst x11||Analyst x10||Analyst x3||Analyst x1||Analyst x1||Est @ 4.06%||Est @ 3.36%||Est @ 2.88%||Est @ 2.54%||Est @ 2.3%|
|Present Value ($, Millions) Discounted @ 6.3%||US$2.0k||US$2.0k||US$2.0k||US$2.1k||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$20b
We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. The Gordon Growth formula is used to calculate Terminal Value at a future annual growth rate equal to the 10-year government bond rate of 1.7%. We discount the terminal cash flows to today's value at a cost of equity of 6.3%.
Terminal Value (TV)= FCF2029 × (1 + g) ÷ (r – g) = US$3.2b× (1 + 1.7%) ÷ 6.3%– 1.7%) = US$72b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$72b÷ ( 1 + 6.3%)10= US$39b
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$58b. The last step is to then divide the equity value by the number of shares outstanding. Compared to the current share price of US$97.7, the company appears a touch undervalued at a 29% 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.
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. 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 Waste Management 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 6.3%, which is based on a levered beta of 0.844. 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, DCF calculation 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.
