Key Insights

  • Exasol's estimated fair value is €8.42 based on 2 Stage Free Cash Flow to Equity
  • Exasol is estimated to be 47% undervalued based on current share price of €4.48
  • When compared to theindustry average discount to fair value of 33%, Exasol's competitors seem to be trading at a lesser discount

Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Exasol AG (ETR:EXL) as an investment opportunity by taking the expected future cash flows and discounting them to their present value. We will take advantage of the Discounted Cash Flow (DCF) model for this purpose. Before you think you won't be able to understand it, just read on! It's actually much less complex than you'd imagine.

We generally believe that a company's value is the present value of all of the cash it will generate in the future. However, a DCF is just one valuation metric among many, and it is not without flaws. 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.

Is Exasol Fairly Valued?

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:

Present Value (€, Millions) Discounted @ 6.0% -€3.0 €1.9 €3.1 €4.6 €5.9 €7.1 €7.9 €8.5 €8.7 €8.8

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = €54m

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 (0.2%) 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 6.0%.

Terminal Value (TV)= FCF2032 × (1 + g) ÷ (r – g) = €16m× (1 + 0.2%) ÷ (6.0%– 0.2%) = €269m

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= €269m÷ ( 1 + 6.0%)10= €150m

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is €203m. To get the intrinsic value per share, we divide this by the total number of shares outstanding. Relative to the current share price of €4.5, the company appears quite good value at a 47% 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.

Important 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 Exasol 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 6.0%, which is based on a levered beta of 0.989. 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. Rather it should be seen as a guide to "what assumptions need to be true for this stock to be under/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? For Exasol, we've compiled three fundamental elements you should look at:

  1. Risks: We feel that you should assess the 4 warning signs for Exasol we've flagged before making an investment in the company.
