Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Service Stream Limited (ASX:SSM) as an investment opportunity by taking the expected future cash flows and discounting them to today's value. The Discounted Cash Flow (DCF) model is the tool we will apply to do this. Don't get put off by the jargon, the math behind it is actually quite straightforward.

Remember though, that there are many ways to estimate a company's value, and a DCF is just one method. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.

### The model

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. Where possible we use analyst estimates, but when these aren't available we extrapolate the previous free cash flow (FCF) from the last estimate or 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) forecast

 2021 2022 2023 2024 2025 2026 2027 2028 2029 2030 Levered FCF (A\$, Millions) AU\$34.8m AU\$42.8m AU\$49.2m AU\$46.1m AU\$44.5m AU\$43.7m AU\$43.4m AU\$43.4m AU\$43.7m AU\$44.1m Growth Rate Estimate Source Analyst x4 Analyst x4 Analyst x4 Analyst x1 Est @ -3.5% Est @ -1.87% Est @ -0.73% Est @ 0.06% Est @ 0.62% Est @ 1.01% Present Value (A\$, Millions) Discounted @ 7.2% AU\$32.4 AU\$37.2 AU\$39.8 AU\$34.9 AU\$31.4 AU\$28.7 AU\$26.6 AU\$24.8 AU\$23.3 AU\$21.9

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = AU\$301m

We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. The Gordon Growth formula is used to calculate Terminal Value at a future annual growth rate equal to the 5-year average of the 10-year government bond yield of 1.9%. We discount the terminal cash flows to today's value at a cost of equity of 7.2%.

Terminal Value (TV)= FCF2030 × (1 + g) ÷ (r – g) = AU\$44m× (1 + 1.9%) ÷ (7.2%– 1.9%) = AU\$844m

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= AU\$844m÷ ( 1 + 7.2%)10= AU\$420m

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is AU\$721m. The last step is to then divide the equity value by the number of shares outstanding. Relative to the current share price of AU\$0.9, the company appears quite undervalued at a 49% 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.

### The assumptions

The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the 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 Service Stream 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 7.2%, which is based on a levered beta of 1.128. 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:

Although the valuation of a company is important, it is only one of many factors that you need to assess for 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. Why is the intrinsic value higher than the current share price?
