However, margins will remain under pressure due to wage inflation and potential rupee appreciation, it added.
"For FY15, EBITDA margins are likely to remain under pressure due to wage inflation in Q1 FY15. Ind-Ra expects the Indian rupee to appreciate to around 56-57/USD by end-March 2015, which will further depress EBITDA margins," it said in a statement.
Higher employee use as well as improvements in productivity levels will also help contain margin erosion, it said.
