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. Unfortunately, these high risk investments often have little probability of ever paying off, and many investors pay a price to learn their lesson. 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 ATI (NYSE:ATI), 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.

How Fast Is ATI Growing Its Earnings Per Share?

Strong earnings per share (EPS) results are an indicator of a company achieving solid profits, which investors look upon favourably and so the share price tends to reflect great EPS performance. So a growing EPS generally brings attention to a company in the eyes of prospective investors. It's an outstanding feat for ATI to have grown EPS from US$0.19 to US$2.34 in just one year. While it's difficult to sustain growth at that level, it bodes well for the company's outlook for the future.

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. ATI maintained stable EBIT margins over the last year, all while growing revenue 15% to US$4.1b. That's encouraging news for the company!

Are ATI Insiders Aligned With All Shareholders?

Owing to the size of ATI, 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$49m. That shows significant buy-in, and may indicate conviction in the business strategy. Even though that's only about 0.9% of the company, it's enough money to indicate alignment between the leaders of the business and ordinary shareholders.

Should You Add ATI To Your Watchlist?

ATI's earnings have taken off in quite an impressive fashion. That EPS growth certainly is attention grabbing, and the large insider ownership only serves to further stoke our interest. At times fast EPS growth is a sign the business has reached an inflection point, so there's a potential opportunity to be had here. Based on the sum of its parts, we definitely think its worth watching ATI very closely. Even so, be aware that ATI is showing 1 warning sign in our investment analysis , you should know about...
