Today we will run through one way of estimating the intrinsic value of Enel SpA (BIT:ENEL) by taking the expected future cash flows and discounting them to their present value. I will use 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. 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.
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)||€3.39b||€4.29b||€5.15b||€5.79b||€6.24b||€6.60b||€6.90b||€7.14b||€7.34b||€7.51b|
|Growth Rate Estimate Source||Analyst x13||Analyst x12||Analyst x9||Analyst x4||Est @ 7.83%||Est @ 5.84%||Est @ 4.45%||Est @ 3.48%||Est @ 2.8%||Est @ 2.32%|
|Present Value (€, Millions) Discounted @ 7.8%||€3.1k||€3.7k||€4.1k||€4.3k||€4.3k||€4.2k||€4.1k||€3.9k||€3.7k||€3.5k|
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = €39b
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 10-year government bond rate of 1.2%. We discount the terminal cash flows to today's value at a cost of equity of 7.8%.
Terminal Value (TV)= FCF2029 × (1 + g) ÷ (r – g) = €7.5b× (1 + 1.2%) ÷ 7.8%– 1.2%) = €115b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= €115b÷ ( 1 + 7.8%)10= €54b
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 €93b. In the final step we divide the equity value by the number of shares outstanding. Compared to the current share price of €7.2, the company appears a touch undervalued at a 22% 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. 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 Enel 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 7.8%, which is based on a levered beta of 0.800. 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 Enel, I've compiled three essential factors you should further research:
