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

We would caution that there are many ways of valuing a company and, like the DCF, each technique has advantages and disadvantages in certain scenarios. If you still have some burning questions about this type of valuation, take a look at the Simply Wall St analysis model.

Step By Step Through The Calculation

We have to calculate the value of ONE Gas 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 (2.8%). The expected dividend per share is then discounted to today's value at a cost of equity of 6.2%. Relative to the current share price of US$77.8, the company appears about fair value at a 1.3% 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)

= US$2.7 / (6.2% – 2.8%)

= US$78.8

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 ONE Gas 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 6.2%, 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.

Looking Ahead:

Although the valuation of a company is important, it shouldn't be the only metric you look at when researching a company. It's not possible to obtain a foolproof valuation with a DCF model. 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. For ONE Gas, we've put together three additional factors you should consider:

1. Risks: Be aware that ONE Gas is showing 2 warning signs in our investment analysis , and 1 of those is a bit concerning...
