Investors are often guided by the idea of discovering 'the next big thing', even if that means buying 'story stocks' without any revenue, let alone profit. But as Peter Lynch said in One Up On Wall Street, 'Long shots almost never pay off.' While a well funded company may sustain losses for years, it will need to generate a profit eventually, or else investors will move on and the company will wither away.

In contrast to all that, many investors prefer to focus on companies like Pentair (NYSE:PNR), which has not only revenues, but also profits. Now this is not to say that the company presents the best investment opportunity around, but profitability is a key component to success in business.

Pentair's Earnings Per Share Are Growing

If you believe that markets are even vaguely efficient, then over the long term you'd expect a company's share price to follow its earnings per share (EPS) outcomes. That makes EPS growth an attractive quality for any company. Impressively, Pentair has grown EPS by 21% per year, compound, in the last three years. If the company can sustain that sort of growth, we'd expect shareholders to come away satisfied.

It's often helpful to take a look at earnings before interest and tax (EBIT) margins, as well as revenue growth, to get another take on the quality of the company's growth. It seems Pentair is pretty stable, since revenue and EBIT margins are pretty flat year on year. That's not bad, but it doesn't point to ongoing future growth, either.

In the chart below, you can see how the company has grown earnings and revenue, over time. Click on the chart to see the exact numbers.

Of course the knack is to find stocks that have their best days in the future, not in the past. You could base your opinion on past performance, of course, but you may also want to check this interactive graph of professional analyst EPS forecasts for Pentair.

Are Pentair Insiders Aligned With All Shareholders?

Owing to the size of Pentair, we wouldn't expect insiders to hold a significant proportion of the company. But we do take comfort from the fact that they are investors in the company. As a matter of fact, their holding is valued at US$48m. That's a lot of money, and no small incentive to work hard. Despite being just 0.4% of the company, the value of that investment is enough to show insiders have plenty riding on the venture.

While it's always good to see some strong conviction in the company from insiders through heavy investment, it's also important for shareholders to ask if management compensation policies are reasonable. Well, based on the CEO pay, you'd argue that they are indeed. Our analysis has discovered that the median total compensation for the CEOs of companies like Pentair, with market caps over US$8.0b, is about US$12m.
