Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Vanda Pharmaceuticals Inc. (NASDAQ:VNDA) as an investment opportunity by taking the expected future cash flows and discounting them to today's value. We will use the Discounted Cash Flow (DCF) model on this occasion. There's really not all that much to it, even though it might appear quite complex.

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. 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

We use what is known as a 2-stage model, which simply means we have two different periods of growth rates for the company's cash flows. Generally the first stage is higher growth, and the second stage is a lower growth phase. In the first stage we need to estimate the cash flows to the business over the next ten years. Seeing as no analyst estimates of free cash flow are available to us, we have extrapolate the previous free cash flow (FCF) from the company's last reported value. We assume companies with shrinking free cash flow will slow their rate of shrinkage, and that companies with growing free cash flow will see their growth rate slow, over this period. We do this to reflect that growth tends to slow more in the early years than it does in later years.

A DCF is all about the idea that a dollar in the future is less valuable than a dollar today, so we need to discount the sum of these future cash flows to arrive at a present value estimate:

10-year free cash flow (FCF) estimate

2022 2023 2024 2025 2026 2027 2028 2029 2030 2031
Levered FCF ($, Millions) US$57.0m US$58.3m US$59.6m US$60.8m US$62.1m US$63.4m US$64.6m US$65.9m US$67.2m US$68.6m
Growth Rate Estimate Source Est @ 2.43% Est @ 2.29% Est @ 2.19% Est @ 2.12% Est @ 2.07% Est @ 2.04% Est @ 2.01% Est @ 2% Est @ 1.99% Est @ 1.98%
Present Value ($, Millions) Discounted @ 6.1% US$53.7 US$51.8 US$49.9 US$48.1 US$46.2 US$44.5 US$42.8 US$41.1 US$39.5 US$38.0

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$455m

We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. For a number of reasons a very conservative growth rate is used that cannot exceed that of a country's GDP growth. In this case we have used the 5-year average of the 10-year government bond yield (2.0%) to estimate future growth. In the same way as with the 10-year 'growth' period, we discount future cash flows to today's value, using a cost of equity of 6.1%.

Terminal Value (TV)= FCF2031 × (1 + g) ÷ (r – g) = US$69m× (1 + 2.0%) ÷ (6.1%– 2.0%) = US$1.7b

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$1.7b÷ ( 1 + 6.1%)10= US$942m

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is US$1.4b. In the final step we divide the equity value by the number of shares outstanding. Compared to the current share price of US$17.1, the company appears quite good value at a 32% 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.

Important assumptions

Now 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 Vanda Pharmaceuticals 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 6.1%, which is based on a levered beta of 0.940. 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. 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 instance, if the terminal value growth rate is adjusted slightly, it can dramatically alter the overall result. Why is the intrinsic value higher than the current share price?
