Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Envista Holdings Corporation (NYSE:NVST) as an investment opportunity by taking the forecast future cash flows of the company and discounting them back to today's value. One way to achieve this is by employing the Discounted Cash Flow (DCF) model. Don't get put off by the jargon, the math behind it is actually quite straightforward.
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 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 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.
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) forecast
|Levered FCF ($, Millions)||US$323.2m||US$356.5m||US$434.0m||US$465.2m||US$491.2m||US$513.3m||US$532.5m||US$549.4m||US$564.8m||US$579.2m|
|Growth Rate Estimate Source||Analyst x3||Analyst x2||Analyst x1||Est @ 7.18%||Est @ 5.6%||Est @ 4.5%||Est @ 3.73%||Est @ 3.18%||Est @ 2.8%||Est @ 2.54%|
|Present Value ($, Millions) Discounted @ 6.1%||US$305||US$317||US$363||US$367||US$365||US$359||US$351||US$342||US$331||US$320|
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$3.4b
The second stage is also known as Terminal Value, this is the business's cash flow after the first stage. The Gordon Growth formula is used to calculate Terminal Value at a future annual growth rate equal to the 5-year average of the 10-year government bond yield of 1.9%. We discount the terminal cash flows to today's value at a cost of equity of 6.1%.
Terminal Value (TV)= FCF2031 × (1 + g) ÷ (r – g) = US$579m× (1 + 1.9%) ÷ (6.1%– 1.9%) = US$14b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$14b÷ ( 1 + 6.1%)10= US$7.8b
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$11b. The last step is to then divide the equity value by the number of shares outstanding. Compared to the current share price of US$47.2, the company appears quite good value at a 32% 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.
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 Envista Holdings 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 6.1%, which is based on a levered beta of 0.990. 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 shouldn't be the only metric you look at when researching a company. It's not possible to obtain a foolproof valuation with a DCF model. Instead the best use for a DCF model is to test certain assumptions and theories to see if they would lead to the company being undervalued or overvalued. For example, changes in the company's cost of equity or the risk free rate can significantly impact the valuation. What is the reason for the share price sitting below the intrinsic value?
