How far off is Polypipe Group plc (LON:PLP) from its intrinsic value? Using the most recent financial data, we'll take a look at whether the stock is fairly priced by taking the expected future cash flows and discounting them to today's value. We will use the Discounted Cash Flow (DCF) model on this occasion. 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. If you still have some burning questions about this type of valuation, take a look at the Simply Wall St analysis model.
What's the estimated valuation?
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. 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
Levered FCF (£, Millions)
Growth Rate Estimate Source
Est @ 15.77%
Est @ 11.34%
Est @ 8.24%
Est @ 6.07%
Est @ 4.55%
Est @ 3.48%
Est @ 2.74%
Est @ 2.22%
Present Value (£, Millions) Discounted @ 8.5%
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = UK£419m
The second stage is also known as Terminal Value, this is the business's cash flow after 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 (1.0%) 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 8.5%.
Terminal Value (TV)= FCF2030 × (1 + g) ÷ (r – g) = UK£83m× (1 + 1.0%) ÷ (8.5%– 1.0%) = UK£1.1b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= UK£1.1b÷ ( 1 + 8.5%)10= UK£497m
The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is UK£916m. In the final step we divide the equity value by the number of shares outstanding. Relative to the current share price of UK£5.4, 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.
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. Part of investing is coming up with your own evaluation of a company's future performance, so try the calculation yourself and check your own 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 Polypipe Group 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 8.5%, which is based on a levered beta of 1.256. 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.
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. The DCF model is not a perfect stock valuation tool. Preferably you'd apply different cases and assumptions and see how they would impact the company's valuation. 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.
