Global business process and technology management firm Genpact on Tuesday said it expects annual revenue between $1.84-$1.88 billion this year and would continue to invest for growth.

The company recorded revenue of $1.60 billion for full-year ended December 31, 2011, up 27.1 per cent from $1.26 billion in 2010.

“In an environment where our clients are facing ongoing macro-economic uncertainty and volatility, we expect annual revenues for 2012 between $1.84 billion and $1.88 billion,” president and CEO NV ‘Tiger’ Tyagarajan said in a statement.

He said the company would continue to invest for growth and expected adjusted income from operations to grow 16 per cent to 16.5 per cent in 2012.

The company said revenue from global clients represented around 69.8 per cent of Genpact's total revenues in 2011 while the remaining 30.2 per cent of revenues came from GE. GE revenues increased 1.6 per cent in 2011.

The company had 55,400 employees worldwide as of December 31, 2011, up from 43,900 at end of 2010. The attrition rate in 2011, measured from day one, was 30 per cent, down from 31 per cent in 2010.

Revenue per employee in 2011 was $34,100, up from $31,100 in 2010, the company said.

Genpact’s net income for the fourth quarter ended December 31, 2011,was $61.1 million, up 32.8 per cent from $ 46 million in the fourth quarter of 2010. Net income margin for the fourth quarter of 2011 was 13.8 per cent, up from 13.5 per cent in corresponding quarter of 2010.

“Genpact won a record 107 new logos during the year and expanded relationships with existing clients across all size-of-engagement categories. The number of clients in the category from $1 million to $5 million of annual revenues grew the fastest to 121 from 64 at the end of 2010,” Tyagarajan said.

“Such combination of new logo wins, expansion of existing client relationships and strengthened domain capabilities would lead to the company’s future growth,” he said.

Net income attributable to Genpact shareholders was $184.3 million, up 29.6 per cent from $142.2 million in 2010. Similarly, net income margin for 2011 was 11.5 per cent, up from 11.3 per cent in 2010, Genpact said.
