Analysts said Nilekani's return would provide some much needed stability to India's No.2 IT services exporter that has been reeling since Vishal Sikka resigned as its CEO on Aug. 18, blaming Murthy for creating an "untenable atmosphere". The new chairman of Infosys told investors on Friday his priorities were to find a CEO, reconstitute the board and shape future strategy. Nilekani's "return to Infosys gives it the best start in six years in regaining leadership stability, strategic relevance and resolving cultural battles", CLSA wrote in a note to clients. The brokerage raised its rating on Infosys to "buy" from "underperform". Brokerage Jefferies said the appointment would likely lay to rest any issues with founders, helping client and employee retention at the firm.
