Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Grifols, S.A. ( BME:GRF ) as an investment opportunity by projecting its future cash flows and then discounting them to today's value. I will use the Discounted Cash Flow (DCF) model. It may sound complicated, but actually it is quite simple!
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. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model .

Crunching the numbers
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:

Levered FCF (€, Millions) | €798.9m | €918.4m | €1.4b | €1.6b | €1.8b | €2.0b | €2.2b | €2.3b | €2.4b | €2.5b |

Present Value (€, Millions) Discounted @ 13.65% | €702.9 | €711.0 | €926.7 | €968.3 | €967.7 | €936.3 | €885.1 | €822.8 | €756.0 | €688.8 |
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF)
= €8.4b
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 1.5%. We discount the terminal cash flows to today's value at a cost of equity of 13.7%.
Terminal Value (TV) = FCF _{ 2029 } × (1 + g) ÷ (r – g) = €2.5b × (1 + 1.5%) ÷ (13.7% – 1.5%) = €21b
Present Value of Terminal Value (PVTV) = TV / (1 + r) ^{ 10 } = €€21b ÷ ( 1 + 13.7%) ^{ 10 } = €5.77b
The total value is the sum of cash flows for the next ten years plus the discounted terminal value, which results in the Total Equity Value, which in this case is €14.13b. In the final step we divide the equity value by the number of shares outstanding. This results in an intrinsic value estimate of €20.66 . Relative to the current share price of €27.1, the company appears potentially overvalued at the time of writing. Remember though, that this is just an approximate valuation, and like any complex formula - garbage in, garbage out.
Important 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 Grifols 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 13.7%, which is based on a levered beta of 1.483. 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:
Valuation is only one side of the coin in terms of building your investment thesis, and it shouldn’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 Grifols, I've put together three relevant factors you should look at:
