Does the December share price for Keppel Infrastructure Trust (SGX:A7RU) reflect what it's really worth? Today, we will estimate the stock's intrinsic value by taking the expected future cash flows and discounting them to today's value. We will use the Discounted Cash Flow (DCF) model on this occasion. Believe it or not, it's not too difficult to follow, as you'll see from our example!

Remember though, that there are many ways to estimate a company's value, and a DCF is just one method. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.

Crunching The Numbers

We have to calculate the value of Keppel Infrastructure Trust slightly differently to other stocks because it is a gas utilities company. 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. 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 (1.9%). The expected dividend per share is then discounted to today's value at a cost of equity of 6.3%. Compared to the current share price of S$0.5, the company appears a touch undervalued at a 29% discount to where the stock price trades currently. Valuations are imprecise instruments though, rather like a telescope - move a few degrees and end up in a different galaxy. Do keep this in mind.

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

= S$0.04 / (6.3% – 1.9%)

= S$0.8

Important 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. 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 Keppel Infrastructure Trust 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 6.3%, 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.
