Key Insights

  • The projected fair value for BioNTech is US$72.42 based on 2 Stage Free Cash Flow to Equity
  • BioNTech's US$94.10 share price signals that it might be 30% overvalued
  • Our fair value estimate is 43% lower than BioNTech's analyst price target of €127

In this article we are going to estimate the intrinsic value of BioNTech SE (NASDAQ:BNTX) by projecting its future cash flows and then discounting them to today's value. The Discounted Cash Flow (DCF) model is the tool we will apply to do this. Before you think you won't be able to understand it, just read on! It's actually much less complex than you'd imagine.

Companies can be valued in a lot of ways, so we would point out that a DCF is not perfect for every situation. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.

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. To start off with, we need to estimate 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, and so the sum of these future cash flows is then discounted to today's value:

Levered FCF (€, Millions) €707.1m €34.9m €17.0m €12.0m €227.0m €353.4m €493.7m €634.2m €764.9m €880.5m

Present Value (€, Millions) Discounted @ 6.1% €667 €31.0 €14.2 €9.5 €169 €248 €327 €396 €450 €488

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = €2.8b

The second stage is also known as Terminal Value, this is the business's cash flow after the first stage. 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 (2.3%) 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)= FCF2033 × (1 + g) ÷ (r – g) = €881m× (1 + 2.3%) ÷ (6.1%– 2.3%) = €24b

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= €24b÷ ( 1 + 6.1%)10= €13b

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is €16b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. Compared to the current share price of US$94.1, the company appears slightly overvalued at the time of writing. 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. 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 BioNTech 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 0.824. 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.

SWOT Analysis for BioNTech

Strength
  • Debt is not viewed as a risk.
Weakness
  • Earnings declined over the past year.
Opportunity
  • Good value based on P/E ratio compared to estimated Fair P/E ratio.
Threat
  • Annual earnings are forecast to decline for the next 4 years.

Next Steps:

Valuation is only one side of the coin in terms of building your investment thesis, and it is only one of many factors that you need to assess for a company. It's not possible to obtain a foolproof valuation with a DCF model. Rather it should be seen as a guide to "what assumptions need to be true for this stock to be under/overvalued?" For instance, if the terminal value growth rate is adjusted slightly, it can dramatically alter the overall result. Why is the intrinsic value lower than the current share price? For BioNTech, there are three relevant factors you should further examine:
