Today we will run through one way of estimating the intrinsic value of Amiad Water Systems Ltd. (LON:AFS) by taking the expected future cash flows and discounting them to today's value. This is done 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. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.
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. In the first stage we need to estimate the cash flows to the business over the next ten years. 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) estimate
|Levered FCF ($, Millions)||$4.49||$4.79||$5.09||$5.29||$5.59||$5.81||$5.98||$6.14||$6.27||$6.38|
|Growth Rate Estimate Source||Analyst x1||Analyst x1||Analyst x1||Analyst x1||Analyst x1||Est @ 3.87%||Est @ 3.08%||Est @ 2.52%||Est @ 2.13%||Est @ 1.86%|
|Present Value ($, Millions) Discounted @ 8.73%||$4.13||$4.05||$3.96||$3.79||$3.68||$3.51||$3.33||$3.14||$2.95||$2.76|
Present Value of 10-year Cash Flow (PVCF)= $35.31m
"Est" = FCF growth rate estimated by Simply Wall St
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 (1.2%) 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 8.7%.
Terminal Value (TV) = FCF2029 × (1 + g) ÷ (r – g) = US$6.4m × (1 + 1.2%) ÷ (8.7% – 1.2%) = US$86m
Present Value of Terminal Value (PVTV) = TV / (1 + r)10 = $US$86m ÷ ( 1 + 8.7%)10 = $37.32m
The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is $72.64m. The last step is to then divide the equity value by the number of shares outstanding. This results in an intrinsic value estimate in the company’s reported currency of $3.21. However, AFS’s primary listing is in Israel, and 1 share of AFS in USD represents 0.793 ( USD/ GBP) share of AIM:AFS, so the intrinsic value per share in GBP is £2.54. Relative to the current share price of £2.2, the company appears about fair value at a 13% discount to where the stock price trades currently. The assumptions in any calculation have a big impact on the valuation, so it is better to view this as a rough estimate, not precise down to the last cent.
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 Amiad Water Systems 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 8.7%, which is based on a levered beta of 1.258. 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.
