Today we'll do a simple run through of a valuation method used to estimate the attractiveness of SGL Carbon SE (ETR:SGL) as an investment opportunity by taking the expected future cash flows and discounting them to today's value. This will be done using the Discounted Cash Flow (DCF) model. Before you think you won't be able to understand it, just read on! It's actually much less complex than you'd imagine.
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.
Our analysis indicates that SGL is potentially undervalued!
The Model
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. 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) forecast
2023 | 2024 | 2025 | 2026 | 2027 | 2028 | 2029 | 2030 | 2031 | 2032 | |
Levered FCF (€, Millions) | €57.5m | €59.3m | €60.4m | €61.2m | €61.8m | €62.2m | €62.5m | €62.7m | €62.9m | €63.0m |
Growth Rate Estimate Source | Analyst x3 | Analyst x3 | Est @ 1.92% | Est @ 1.35% | Est @ 0.95% | Est @ 0.68% | Est @ 0.48% | Est @ 0.35% | Est @ 0.25% | Est @ 0.19% |
Present Value (€, Millions) Discounted @ 6.7% | €53.9 | €52.1 | €49.8 | €47.3 | €44.8 | €42.3 | €39.8 | €37.5 | €35.2 | €33.1 |
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = €435m
After calculating the present value of future cash flows in the initial 10-year period, we need to calculate the Terminal Value, which accounts for all future cash flows beyond 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 (0.03%) 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 6.7%.
Terminal Value (TV)= FCF2032 × (1 + g) ÷ (r – g) = €63m× (1 + 0.03%) ÷ (6.7%– 0.03%) = €951m
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= €951m÷ ( 1 + 6.7%)10= €500m
The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is €935m. In the final step we divide the equity value by the number of shares outstanding. Relative to the current share price of €6.3, the company appears about fair value at a 17% 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.
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 SGL Carbon 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 6.7%, which is based on a levered beta of 1.416. 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 SGL Carbon
- Net debt to equity ratio below 40%.
- Interest payments on debt are not well covered.
- Annual revenue is forecast to grow faster than the German market.
- Good value based on P/E ratio and estimated fair value.
- Debt is not well covered by operating cash flow.
- Annual earnings are forecast to grow slower than the German market.
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. 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 SGL Carbon, we've put together three further items you should explore:
