Key Insights

• Atmos Energy's estimated fair value is US$118 based on Dividend Discount Model
• Atmos Energy's US$143 share price signals that it might be 21% overvalued
• The US$148 analyst price target for ATO is 26% more than our estimate of fair value

How far off is Atmos Energy Corporation (NYSE:ATO) from its intrinsic value? Using the most recent financial data, we'll take a look at whether the stock is fairly priced by taking the expected future cash flows and discounting them to today's value. The Discounted Cash Flow (DCF) model is the tool we will apply to do this. Models like these may appear beyond the comprehension of a lay person, but they're fairly easy to follow.

We generally believe that a company's value is the present value of all of the cash it will generate in the future. However, a DCF is just one valuation metric among many, and it is not without flaws. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.

Is Atmos Energy Fairly Valued?

As Atmos Energy operates in the gas 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. 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. The dividend is expected to grow at an annual growth rate equal to the 5-year average of the 10-year government bond yield of 2.6%. We then discount this figure to today's value at a cost of equity of 5.9%. Compared to the current share price of US$143, the company appears slightly overvalued at the time of writing. 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)

= US$3.9 / (5.9% – 2.6%)

= US$118

Important Assumptions

The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the 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 Atmos Energy 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 5.9%, 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 Atmos Energy

Next Steps:

Whilst important, the DCF calculation is only one of many factors that you need to assess for a company. The DCF model is not a perfect stock valuation tool. 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. Can we work out why the company is trading at a premium to intrinsic value?
