It's common for many investors, especially those who are inexperienced, to buy shares in companies with a good story even if these companies are loss-making. 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.

Despite being in the age of tech-stock blue-sky investing, many investors still adopt a more traditional strategy; buying shares in profitable companies like Republic Services (NYSE:RSG). 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.

How Fast Is Republic Services Growing?

If a company can keep growing earnings per share (EPS) long enough, its share price should eventually follow. Therefore, there are plenty of investors who like to buy shares in companies that are growing EPS. Shareholders will be happy to know that Republic Services' EPS has grown 20% each year, compound, over three years. If growth like this continues on into the future, then shareholders will have plenty to smile about.

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.
