$NOV - In the last three years the company has shown a tremendous performance due to an increase in oil rigs in the years 2011 and 2012, and this is the reason the company has managed to grow its revenues at a Compound Annual Growth Rate (CAGR) of 28.04%.

Despite tough competition, the company's margins were slightly hurt last year, with a 17.7% operating margin and a 13% net margin respectively, but the company successfully raised its return on invested capital from 11.32% in 2011 to 11.83%in 2012, respectively.

The company has recently raised debt to finance in its operations to meet the increasing demand.
