Polaris has been the company on the move in 2011, and its second quarter earnings show why. Gobbling up Indian and then later GEM, Polaris has shown that it has an appetite for growth, which has been fueled by its strong sales, which have increased in revenue by 41% over Q2 2010. Perhaps more impressive is that the American company has parlayed that increase in revenue into a 90% increase in net income over the same time period, which has been a boon for the company’s shareholders and a testament to the company’s reduced-cost structures.
