India's second largest IT services exporter Cognizant Company grew its revenues 6.2 per cent over the September quarter to $2.74 billion, beating all its top tier rivals.

TCS reported flat growth in the quarter while Infosys and Wipro grew 0.8 per cent and 1.3 per cent, respectively.

For more spectacular is the company's guidance for 2015 - Cognizant, listed on the Nasdaq, follows the Jan-Dec calendar. It expects to grow 19 per cent this year, better than the 16 per cent it managed in 2014.

The company completed the integration of its $2.8-billion acquisition of healthcare IT Company TriZetto in the December quarter.

Excluding TriZetto, the company would have grown 3.1 per cent in the December quarter. And TriZetto is now likely to add around $700 million to Cognizant's revenues in 2015.  

There might be a chance of the divergence between Cognizant's growth and the rest of the industry because of the geographical mix. Cognizant's exposure to North America, a geography whose economy is looking up, is far higher than many companies.

In the three months to December, nearly 78 per cent of its revenues were generated in this geography.
