Wipro Ltd CEO Abidali Z Neemuchwala is leaving after a turbulent four-years during which growth stalled and the Indian IT-services giant fell farther behind rivals Infosys and TCS. Mr Neemuchwala will remain at his post until a new CEO is appointed, the company said in a statement. Wipro, whose clients include Levi Strauss & Co. and Pitney Bowes, slid as much as 2.3% Friday.
