Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Probi AB (publ) (STO:PROB) as an investment opportunity by taking the expected future cash flows and discounting them to their present value. I will be using the Discounted Cash Flow (DCF) model. Don't get put off by the jargon, the math behind it is actually quite straightforward.
Remember though, that there are many ways to estimate a company's value, and a DCF is just one method. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.
We're using the 2-stage growth model, which simply means we take in account two stages of company's growth. In the initial period the company may have a higher growth rate and the second stage is usually assumed to have a stable growth rate. 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 are 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.
A DCF is all about the idea that a dollar in the future is less valuable than a dollar today, so we discount the value of these future cash flows to their estimated value in today's dollars:
10-year free cash flow (FCF) estimate
|Levered FCF (SEK, Millions)||kr70.0||kr138||kr175||kr202||kr224||kr242||kr256||kr266||kr274||kr280|
|Growth Rate Estimate Source||Analyst x2||Analyst x2||Analyst x2||Est @ 15.69%||Est @ 11.11%||Est @ 7.91%||Est @ 5.67%||Est @ 4.1%||Est @ 3%||Est @ 2.23%|
|Present Value (SEK, Millions) Discounted @ 8.35%||kr64.6||kr117||kr137||kr146||kr150||kr150||kr146||kr140||kr133||kr126|
Present Value of 10-year Cash Flow (PVCF)= SEK1.31b
"Est" = FCF growth rate estimated by Simply Wall St
We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. 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 0.4%. We discount the terminal cash flows to today's value at a cost of equity of 8.3%.
Terminal Value (TV) = FCF2029 × (1 + g) ÷ (r – g) = kr280m × (1 + 0.4%) ÷ (8.3% – 0.4%) = kr3.6b
Present Value of Terminal Value (PVTV) = TV / (1 + r)10 = SEKkr3.6b ÷ ( 1 + 8.3%)10 = SEK1.60b
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 SEK2.91b. The last step is to then divide the equity value by the number of shares outstanding. This results in an intrinsic value estimate of SEK255.12. Compared to the current share price of SEK343.5, the company appears potentially overvalued at the time of writing. The assumptions in a DCF 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.
Now the most important inputs to a discounted cash flow are the discount rate, and of course, the actual cash flows. If you don't agree with these result, have a go at the calculation yourself and play with the 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 Probi 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 8.3%, which is based on a levered beta of 1.327. 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. 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 Probi, I've compiled three additional aspects you should further examine:
