Calculating The Intrinsic Value Of Northwest Natural Holding Company (NYSE:NWN)

Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Northwest Natural Holding Company (NYSE:NWN) as an investment opportunity by taking the expected future cash flows and discounting them to their present value. One way to achieve this is by employing the Discounted Cash Flow (DCF) model. Believe it or not, it's not too difficult to follow, as you'll see from our example!

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.

Step by step through the calculation

As Northwest Natural Holding 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. 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 (2.0%). The expected dividend per share is then discounted to today's value at a cost of equity of 5.5%. Relative to the current share price of US$45.8, the company appears about fair value at a 15% 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)

= US$1.9 / (5.5% – 2.0%)

= US$53.8

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 Northwest Natural Holding 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 5.5%, 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.

Moving On:

Whilst important, the DCF calculation shouldn't be the only metric you look at when researching 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 example, changes in the company's cost of equity or the risk free rate can significantly impact the valuation.
