centrotherm international isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. When a company doesn't make profits, we'd generally expect to see good revenue growth.

In the last 3 years centrotherm international saw its revenue shrink by 9.2% per year. So the share price gain of 49% per year is quite surprising. It's fair to say shareholders are definitely counting on a bright future.
