In this article we are going to estimate the intrinsic value of Installux S.A. (EPA:ALLUX) 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. Models like these may appear beyond the comprehension of a lay person, but they're fairly easy to follow.

Remember though, that there are many ways to estimate a company's value, and a DCF is just one method. If you still have some burning questions about this type of valuation, take a look at the Simply Wall St analysis model.

### What's the estimated valuation?

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.

Generally we assume that a dollar today is more valuable than a dollar in the future, 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

 2022 2023 2024 2025 2026 2027 2028 2029 2030 2031 Levered FCF (€, Millions) €5.40m €8.00m €8.00m €9.00m €9.69m €10.2m €10.6m €10.9m €11.2m €11.3m Growth Rate Estimate Source Analyst x1 Analyst x1 Analyst x1 Analyst x1 Est @ 7.69% Est @ 5.49% Est @ 3.95% Est @ 2.87% Est @ 2.12% Est @ 1.59% Present Value (€, Millions) Discounted @ 6.6% €5.1 €7.0 €6.6 €7.0 €7.0 €7.0 €6.8 €6.5 €6.3 €6.0

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = €65m

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 0.4%. We discount the terminal cash flows to today's value at a cost of equity of 6.6%.

Terminal Value (TV)= FCF2031 × (1 + g) ÷ (r – g) = €11m× (1 + 0.4%) ÷ (6.6%– 0.4%) = €181m

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= €181m÷ ( 1 + 6.6%)10= €95m

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is €160m. The last step is to then divide the equity value by the number of shares outstanding. Relative to the current share price of €494, the company appears about fair value at a 13% 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.

### The assumptions

The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the 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 Installux 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 6.6%, which is based on a levered beta of 1.207. 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 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. For Installux, we've put together three essential elements you should explore:
