Calculating The Fair Value Of Iberdrola, S.A. (BME:IBE)

Key Insights

• Iberdrola's estimated fair value is €13.19 based on Dividend Discount Model
• With €13.45 share price, Iberdrola appears to be trading close to its estimated fair value
• Our fair value estimate is 5.8% lower than Iberdrola's analyst price target of €14.00

Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Iberdrola, S.A. (BME:IBE) as an investment opportunity by projecting its future cash flows and then discounting them to today's value. The Discounted Cash Flow (DCF) model is the tool we will apply to do this. There's really not all that much to it, even though it might appear quite complex.

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.

The Calculation

We have to calculate the value of Iberdrola slightly differently to other stocks because it is a electric utilities company. 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. This often underestimates the value of a stock, but it can still be good as a comparison to competitors. The 'Gordon Growth Model' is used, which simply assumes that dividend payments will continue to increase at a sustainable growth rate forever. 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 (1.8%). The expected dividend per share is then discounted to today's value at a cost of equity of 6.7%. Relative to the current share price of €13.4, the company appears around fair value 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)

= €0.6 / (6.7% – 1.8%)

= €13.2

Important Assumptions

Now the most important inputs to a discounted cash flow are the discount rate, and of course, the actual cash flows. You don't have to agree with these inputs, I recommend redoing the calculations yourself and playing with them. 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 Iberdrola 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 6.7%, 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.

SWOT Analysis for Iberdrola

Moving On:

Although the valuation of a company is important, it ideally won't be the sole piece of analysis you scrutinize for a company. The DCF model is not a perfect stock valuation tool. Preferably you'd apply different cases and assumptions and see how they would impact the company's valuation. 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. For Iberdrola, there are three relevant aspects you should assess:

1. Risks: Be aware that Iberdrola is showing 4 warning signs in our investment analysis , and 1 of those doesn't sit too well with us...
