On a quarter-on-quarter basis, iGate's net income rose by 3.76 per cent and revenues were up by 2 per cent.
Vemuri further said: "We have successfully finished regrouping the organisation into vertical-based business units that bring in more industry knowledge and solutions, move us closer to the customer, and increase the depth and accountability to the business."

"I am pleased with our growth in net income in 2013 while we continue to deliver strong earnings per share. In order to better position us to create more shareholder value, we entered into a credit agreement during the fourth quarter and expect this to lower our debt servicing cost and therefore better our earnings and profitability from 2014," iGate CFO Sujit Sircar said.
As of December 31, 2013, iGate had 29,733 employees with a net addition of 1,450.
The company added nine new customers during the fourth quarter, including five Fortune 1000 companies.
