A Look At The Fair Value Of SDI Limited (ASX:SDI)

In this article we are going to estimate the intrinsic value of SDI Limited (ASX:SDI) by estimating the company's future cash flows and discounting them to their present value. This will be done using the Discounted Cash Flow (DCF) model. It may sound complicated, but actually it is quite simple!

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. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.

Step by step through the calculation

We have to calculate the value of SDI slightly differently to other stocks because it is a medical equipment 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 1.8%. We then discount this figure to today's value at a cost of equity of 5.7%. Relative to the current share price of AU$0.8, the company appears around fair value at the time of writing. Remember though, that this is just an approximate valuation, and like any complex formula - garbage in, garbage out.

Value Per Share = Expected Dividend Per Share / (Discount Rate - Perpetual Growth Rate)

= AU$0.03 / (5.7% – 1.8%)

= AU$0.8

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 SDI 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 5.7%, which is based on a levered beta of 0.917. 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.

Next Steps:

Whilst important, the DCF calculation 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.
