Today we'll do a simple run through of a valuation method used to estimate the attractiveness of BioNTech SE (NASDAQ:BNTX) as an investment opportunity by estimating the company's future cash flows and discounting them to their present 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.

We would caution that there are many ways of valuing a company and, like the DCF, each technique has advantages and disadvantages in certain scenarios. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.

### Step by step through the calculation

We are going to use a two-stage DCF model, which, as the name states, takes into account two stages of growth. The first stage is generally a higher growth period which levels off heading towards the terminal value, captured in the second 'steady growth' period. 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, and so the sum of these future cash flows is then discounted to today's value:

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

 2022 2023 2024 2025 2026 2027 2028 2029 2030 2031 Levered FCF (€, Millions) €13.3b €5.58b €3.34b €2.05b €2.12b €1.60b €1.34b €1.19b €1.10b €1.06b Growth Rate Estimate Source Analyst x8 Analyst x8 Analyst x7 Analyst x5 Analyst x5 Est @ -24.41% Est @ -16.51% Est @ -10.98% Est @ -7.11% Est @ -4.4% Present Value (€, Millions) Discounted @ 5.5% €12.6k €5.0k €2.8k €1.7k €1.6k €1.2k €918 €774 €682 €618

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = €28b

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 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 5.5%.

Terminal Value (TV)= FCF2031 × (1 + g) ÷ (r – g) = €1.1b× (1 + 1.9%) ÷ (5.5%– 1.9%) = €30b

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= €30b÷ ( 1 + 5.5%)10= €18b

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is €45b. In the final step we divide the equity value by the number of shares outstanding. Compared to the current share price of US\$170, the company appears about fair value at a 16% 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

Now 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 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 5.5%, which is based on a levered beta of 0.846. 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.

Although the valuation of a company is important, it shouldn't be the only metric you look at when researching a company. The DCF model is not a perfect stock valuation tool. 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 BioNTech, we've put together three relevant factors you should further research:
