Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Renergetica S.p.A. (BIT:REN) as an investment opportunity by taking the foreast future cash flows of the company and discounting them back to today's value. I will use 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.

Is Renergetica fairly valued?

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. 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.

A DCF is all about the idea that a dollar in the future is less valuable than a dollar today, 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

Present Value of 10-year Cash Flow (PVCF)= €21.79m

"Est" = FCF growth rate estimated by Simply Wall St

After calculating the present value of future cash flows in the intial 10-year period, we need to calculate the Terminal Value, which accounts for all future cash flows beyond 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 2.9%. We discount the terminal cash flows to today's value at a cost of equity of 10.2%.

Terminal Value (TV) = FCF2029 × (1 + g) ÷ (r - g) = €3.8m × (1 + 2.9%) ÷ (10.2% - 2.9%) = €54m

Present Value of Terminal Value (PVTV) = TV / (1 + r)10 = €€54m ÷ ( 1 + 10.2%)10 = €20.56m

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is €42.35m. In the final step we divide the equity value by the number of shares outstanding. This results in an intrinsic value estimate of €5.76. Compared to the current share price of €3.22, the company appears quite good value at a 44% 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 assumptions

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 Renergetica 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 10.2%, 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.

Next Steps:

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. What is the reason for the share price to differ from the intrinsic value? For Renergetica, I've compiled three relevant aspects you should look at:
