Today we'll do a simple run through of a valuation method used to estimate the attractiveness of PNM Resources, Inc. (NYSE:PNM) as an investment opportunity by taking the expected future cash flows and discounting them to today's value. This will be done using the Discounted Cash Flow (DCF) model. Models like these may appear beyond the comprehension of a lay person, but they're fairly easy to follow.
Companies can be valued in a lot of ways, so we would point out that a DCF is not perfect for every situation. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.

Crunching The Numbers
We have to calculate the value of PNM Resources slightly differently to other stocks because it is a electric 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. This often underestimates the value of a stock, but it can still be good as a comparison to competitors. We use the Gordon Growth Model, which assumes dividend will grow into perpetuity at a rate that can be sustained. 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 2.1%. We then discount this figure to today's value at a cost of equity of 6.9%. Relative to the current share price of US$45.5, the company appears reasonably expensive 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$1.6 / (6.9% – 2.1%)
= US$33.8
Important Assumptions
Now the most important inputs to a discounted cash flow are the discount rate, and of course, the actual cash flows. Part of investing is coming up with your own evaluation of a company's future performance, so try the calculation yourself and check your own 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 PNM Resources 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 6.9%, 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.
