Today we'll do a simple run through of a valuation method used to estimate the attractiveness of RWE Aktiengesellschaft (ETR:RWE) as an investment opportunity by taking the forecast future cash flows of the company and discounting them back to today's value. We will use the Discounted Cash Flow (DCF) model on this occasion. Before you think you won't be able to understand it, just read on! It's actually much less complex than you'd imagine.

Companies can be valued in a lot of ways, so we would point out that a DCF is not perfect for every situation. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.

The Model

As RWE operates in the renewable energy sector, we need to calculate the intrinsic value slightly differently. Instead of using free cash flows, which are hard to estimate and often not reported by analysts in this industry, dividends per share (DPS) payments are used. Unless a company pays out the majority of its FCF as a dividend, this method will typically underestimate the value of the stock. We use the Gordon Growth Model, which assumes dividend will grow into perpetuity at a rate that can be sustained. For a number of reasons a very conservative growth rate is used that cannot exceed that of a company's Gross Domestic Product (GDP). In this case we used the 5-year average of the 10-year government bond yield (0.5%). The expected dividend per share is then discounted to today's value at a cost of equity of 4.9%. Relative to the current share price of €34.4, the company appears reasonably expensive at the time of writing. Remember though, that this is just an approximate valuation, and like any complex formula - garbage in, garbage out.

Value Per Share = Expected Dividend Per Share / (Discount Rate - Perpetual Growth Rate)

= €1.2 / (4.9% – 0.5%)

= €26.3

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 RWE 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 4.9%, which is based on a levered beta of 0.886. 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.
