How far off is Pentair plc (NYSE:PNR) from its intrinsic value? Using the most recent financial data, we'll take a look at whether the stock is fairly priced by projecting its future cash flows and then discounting them to today's value. This will be done 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. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.
Crunching The Numbers
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. 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.
A DCF is all about the idea that a dollar in the future is less valuable than a dollar today, so we need to discount the sum of these future cash flows to arrive at a present value estimate:
10-year free cash flow (FCF) estimate
|Levered FCF ($, Millions)||US$665.0m||US$658.4m||US$690.4m||US$756.2m||US$784.0m||US$808.9m||US$831.7m||US$853.0m||US$873.3m||US$893.1m|
|Growth Rate Estimate Source||Analyst x7||Analyst x3||Analyst x1||Analyst x1||Est @ 3.68%||Est @ 3.17%||Est @ 2.81%||Est @ 2.56%||Est @ 2.39%||Est @ 2.27%|
|Present Value ($, Millions) Discounted @ 9.0%||US$610||US$555||US$534||US$536||US$510||US$483||US$456||US$429||US$403||US$378|
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$4.9b
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 5-year average of the 10-year government bond yield of 2.0%. We discount the terminal cash flows to today's value at a cost of equity of 9.0%.
Terminal Value (TV)= FCF2032 × (1 + g) ÷ (r – g) = US$893m× (1 + 2.0%) ÷ (9.0%– 2.0%) = US$13b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$13b÷ ( 1 + 9.0%)10= US$5.5b
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 US$10b. In the final step we divide the equity value by the number of shares outstanding. Compared to the current share price of US$46.2, the company appears a touch undervalued at a 27% discount to where the stock price trades currently. The assumptions in any calculation 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. 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 Pentair 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 9.0%, which is based on a levered beta of 1.196. 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 is only one of many factors that you need to assess for a company. The DCF model is not a perfect stock valuation tool. 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. 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. Can we work out why the company is trading at a discount to intrinsic value? For Pentair, we've put together three relevant aspects you should explore:
- Risks: Consider for instance, the ever-present spectre of investment risk. We've identified 2 warning signs with Pentair (at least 1 which is concerning) , and understanding these should be part of your investment process.
- Future Earnings: How does PNR's growth rate compare to its peers and the wider market? Dig deeper into the analyst consensus number for the upcoming years by interacting with our free analyst growth expectation chart.
