IT services provider Infosys reported today that managing director and CEO Vishal Sikka has stepped down effective immediately. Reuters reported the CEO’s resignation came after a long-running feud with the company’s founders.

“In his notice of resignation to the board, Dr. Sikka reiterated his belief in the great potential of Infosys, but cited among his reasons for leaving a continuous stream of distractions and disruptions over the recent months and quarters, increasingly personal and negative as of late, as preventing management’s ability to accelerate the company’s transformation,” according to an Infosys press release. The company reported that investigations into anonymous allegations have found no merit.

Sikka will remain as executive vice chairman and will hold office until a new permanent CEO and managing replaces him. The company estimates this will be no later than March 31, 2018. Sikka will focus on strategic initiatives, key customer relationships and technology development. He will report to the company’s board.

Infosys also appointed U.B. Pravin Rao as interim CEO. Rao will report to Sikka.

“Vishal has made a seminal contribution to the transformation of Infosys, and he will be remembered for infusing a refreshed sense of direction, purpose and energy in the organization,” said board Chairman R. Seshasayee.
