Today we will run through one way of estimating the intrinsic value of Pennon Group Plc (LON:PNN) by projecting its future cash flows and then discounting them to today's value. Our analysis will employ the Discounted Cash Flow (DCF) model. Don't get put off by the jargon, the math behind it is actually quite straightforward.

Remember though, that there are many ways to estimate a company's value, and a DCF is just one method. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.

The Calculation

As Pennon Group operates in the water utilities sector, we need to calculate the intrinsic value slightly differently. In this approach dividends per share (DPS) are used, as free cash flow is difficult to estimate and often not reported by analysts. 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 (1.9%). The expected dividend per share is then discounted to today's value at a cost of equity of 5.8%. Relative to the current share price of UK£6.3, the company appears quite undervalued at a 36% 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.

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

= UK£0.5 / (5.8% – 1.9%)

= UK£9.9

The Assumptions

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 Pennon Group 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 5.8%, 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.

Next Steps:

Although the valuation of a company is important, it is only one of many factors that you need to assess for a company. DCF models are not the be-all and end-all of investment valuation. Instead the best use for a DCF model is to test certain assumptions and theories to see if they would lead to the company being undervalued or overvalued. For instance, if the terminal value growth rate is adjusted slightly, it can dramatically alter the overall result. What is the reason for the share price sitting below the intrinsic value? For Pennon Group, we've put together three important factors you should assess:

1. Risks: Take risks, for example - Pennon Group has 3 warning signs (and 2 which don't sit too well with us) we think you should know about.
