Today we will run through one way of estimating the intrinsic value of va-Q-tec AG (FRA:VQT) by taking the foreast future cash flows of the company and discounting them back to today's value. I will be using the Discounted Cash Flow (DCF) model. It may sound complicated, but actually it is quite simple!

Remember though, that there are many ways to estimate a company's value, and a DCF is just one method. 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.

### 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. To begin with, we have to get estimates of the next ten years of cash flows. 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 discount the value of these future cash flows to their estimated value in today's dollars:

#### 10-year free cash flow (FCF) estimate

2019 | 2020 | 2021 | 2022 | 2023 | 2024 | 2025 | 2026 | 2027 | 2028 | |

Levered FCF (â‚¬, Millions) | â‚¬-2.00 | â‚¬-0.43 | â‚¬3.20 | â‚¬3.30 | â‚¬5.80 | â‚¬8.04 | â‚¬10.21 | â‚¬12.15 | â‚¬13.78 | â‚¬15.08 |

Growth Rate Estimate Source | Analyst x1 | Analyst x3 | Analyst x2 | Analyst x1 | Analyst x1 | Est @ 38.56% | Est @ 27.06% | Est @ 19.01% | Est @ 13.37% | Est @ 9.43% |

Present Value (â‚¬, Millions) Discounted @ 7.7% | â‚¬-1.86 | â‚¬-0.37 | â‚¬2.56 | â‚¬2.45 | â‚¬4.00 | â‚¬5.15 | â‚¬6.08 | â‚¬6.71 | â‚¬7.07 | â‚¬7.18 |

**Present Value of 10-year Cash Flow (PVCF)**= â‚¬38.98m

"Est" = FCF growth rate estimated by Simply Wall St

The second stage is also known as Terminal Value, this is the business's cash flow after the first stage. The Gordon Growth formula is used to calculate Terminal Value at a future annual growth rate equal to the 10-year government bond rate of 0.2%. We discount the terminal cash flows to today's value at a cost of equity of 7.7%.

**Terminal Value (TV)** = FCF_{2029} Ă— (1 + g) Ă· (r â€“ g) = â‚¬15m Ă— (1 + 0.2%) Ă· (7.7% â€“ 0.2%) = â‚¬202m

**Present Value of Terminal Value (PVTV)** = TV / (1 + r)^{10} = â‚¬â‚¬202m Ă· ( 1 + 7.7%)^{10} = â‚¬96.39m

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is â‚¬135.37m. In the final step we divide the equity value by the number of shares outstanding. **This results in an intrinsic value estimate of â‚¬10.35**. Relative to the current share price of â‚¬7.28, the company appears a touch undervalued at a 30% discount to where the stock price trades currently. Remember though, that this is just an approximate valuation, and like any complex formula - garbage in, garbage out.

### The assumptions

We would point out that 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 va-Q-tec 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 7.7%, which is based on a levered beta of 1.253. 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, DCF calculation shouldnâ€™t be the only metric you look at when researching a company. The DCF model is not a perfect stock valuation tool. 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. What is the reason for the share price to differ from the intrinsic value? For va-Q-tec, I've compiled three further factors you should look at:
