The excitement of investing in a company that can reverse its fortunes is a big draw for some speculators, so even companies that have no revenue, no profit, and a record of falling short, can manage to find investors. But the reality is that when a company loses money each year, for long enough, its investors will usually take their share of those losses. Loss-making companies are always racing against time to reach financial sustainability, so investors in these companies may be taking on more risk than they should.

In contrast to all that, many investors prefer to focus on companies like Fortinet (NASDAQ:FTNT), which has not only revenues, but also profits. Even if this company is fairly valued by the market, investors would agree that generating consistent profits will continue to provide Fortinet with the means to add long-term value to shareholders.

How Quickly Is Fortinet Increasing Earnings Per Share?

Generally, companies experiencing growth in earnings per share (EPS) should see similar trends in share price. Therefore, there are plenty of investors who like to buy shares in companies that are growing EPS. To the delight of shareholders, Fortinet has achieved impressive annual EPS growth of 46%, compound, over the last three years. That sort of growth rarely ever lasts long, but it is well worth paying attention to when it happens.

One way to double-check a company's growth is to look at how its revenue, and earnings before interest and tax (EBIT) margins are changing. The music to the ears of Fortinet shareholders is that EBIT margins have grown from 24% to 31% in the last 12 months and revenues are on an upwards trend as well. Ticking those two boxes is a good sign of growth, in our book.
