Today I will be providing a simple run through of a valuation method used to estimate the attractiveness of SGS SA (VTX:SGSN) as an investment opportunity by taking the expected future cash flows and discounting them to their present value. I will use the discounted cash flows (DCF) model. Don’t get put off by the jargon, the math behind it is actually quite straightforward. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model. If you are reading this and its not August 2018 then I highly recommend you check out the latest calculation for SGS by following the link below.

Is SGSN fairly valued?
I use what is known as a 2-stage model, which simply means we have two different periods of varying growth rates for the company’s cash flows. Generally the first stage is higher growth, and the second stage is a more stable growth phase. To begin with we have to get estimates of the next five years of cash flows. For this I used the consensus of the analysts covering the stock, as you can see below. I then discount the sum of these cash flows to arrive at a present value estimate.
5-year cash flow estimate
2018 | 2019 | 2020 | 2021 | 2022 | |
Levered FCF (CHF, Millions) | CHF742.23 | CHF832.70 | CHF909.74 | CHF1.03k | CHF1.05k |
Source | Analyst x12 | Analyst x14 | Analyst x10 | Analyst x1 | Est @ 2.37% |
Present Value Discounted @ 8.74% | CHF682.56 | CHF704.19 | CHF707.49 | CHF735.19 | CHF692.11 |
Present Value of 5-year Cash Flow (PVCF)= CHF3.52b
We now need to calculate the Terminal Value, which accounts for all the future cash flows after the five years. For a number of reasons a very conservative growth rate is used that cannot exceed that of the GDP. In this case I have used the 10-year government bond rate (3.7%). In the same way as with the 5-year ‘growth’ period, we discount this to today’s value at a cost of equity of 8.7%.
Terminal Value (TV) = FCF2022 × (1 + g) ÷ (r – g) = CHF1.05b × (1 + 3.7%) ÷ (8.7% – 3.7%) = CHF21.69b
Present Value of Terminal Value (PVTV) = TV / (1 + r)5 = CHF21.69b ÷ ( 1 + 8.7%)5 = CHF14.27b
The total value is the sum of cash flows for the next five years and the discounted terminal value, which results in the Total Equity Value, which in this case is CHF17.79b. To get the intrinsic value per share, we divide this by the total number of shares outstanding, or the equivalent number if this is a depositary receipt or ADR. This results in an intrinsic value of CHF2355.65. Relative to the current share price of CHF2563, the stock is fair value, maybe slightly overvalued at the time of writing.
