Today we will run through one way of estimating the intrinsic value of CGN New Energy Holdings Co., Ltd. (HKG:1811) by taking the expected future cash flows and discounting them to today's value. This is done using the Discounted Cash Flow (DCF) model. Don't get put off by the jargon, the math behind it is actually quite straightforward.

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.

The calculation

As CGN New Energy Holdings operates in the renewable energy sector, we need to calculate the intrinsic value slightly differently. Instead of using free cash flows, which are hard to estimate and often not reported by analysts in this industry, dividends per share (DPS) payments are used. 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. 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 10-year government bond rate (2%). The expected dividend per share is then discounted to today's value at a cost of equity of 7.6%. This results in an intrinsic value estimate in the company’s reported currency of $0.17. However, 1811’s primary listing is in Hong Kong, and 1 share of 1811 in USD represents 7.826 ( USD/ HKD) share of SEHK:1811, so the intrinsic value per share in HKD is HK$1.29. Compared to the current share price of HK$0.96, the company appears a touch undervalued at a 26% 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)

= $0.0092 / (7.6% – 2%)

= HK$1.29

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 CGN New Energy Holdings 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 7.6%, which is based on a levered beta of 0.835. 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.
