Pentair's (NYSE:PNR) earnings growth rate lags the 20% CAGR delivered to shareholders

Pentair plc (NYSE:PNR) shareholders might be concerned after seeing the share price drop 13% in the last quarter. But that scarcely detracts from the really solid long term returns generated by the company over five years. In fact, the share price is 136% higher today. Generally speaking the long term returns will give you a better idea of business quality than short periods can. Of course, that doesn't necessarily mean it's cheap now.

While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Over half a decade, Pentair managed to grow its earnings per share at 12% a year. This EPS growth is slower than the share price growth of 19% per year, over the same period. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Pentair, it has a TSR of 154% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

We're pleased to report that Pentair shareholders have received a total shareholder return of 22% over one year. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 20% per year), it would seem that the stock's performance has improved in recent times. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
