BENGALURU (TIP): Infosys president and head of Americas Sandeep Dadlani has resigned, a sudden development that some attributed to growing pressures on the company’s top executives to deliver, following a series of unimpressive quarterly performances.

Dadlani, who has been with Infosys since 2001 and who was also the global head of its manufacturing, retail, CPG (consumer & packaged goods) and logistics vertical, posted on LinkedIn that an “out-of-the-world assignment” was awaiting him.

Sources close to the development said he may be joining Virginia-based confectionery and pet food company Mars, makers of the brands Snickers, M&M’s, Twix and Wrigley , in a digital transformation role. An email sent to Mars and Dadlani did not elicit a response.

Peter Bendor-Samuel, CEO of US-based IT advisory Everest Group, believes Dadlani’s departure is part of the increased pressure on leadership combined with a market eager to hire Infosys talent which is highly regarded. Brokerage firm Edelweiss said Dadlani’s exit yet again raises the stability issue at Infosys, and portends the risk of more exits.

Infosys announced on Friday that Dadlani’s responsibilities would be divided between Karmesh Vaswani, who will be global head of retail, CPG & logistics, and Nitesh Banga, who will be global head of manufacturing. Vaswani was previously the head of Europe for retail, CPG and logistics.

Infosys is expected to fill up the global sales head position that fell vacant in 2013 following the exit of Basab Pradhan. Sources said Infosys president and head of banking, financial services & insurance (BFSI), healthcare and life sciences Mohit Joshi is likely to be given the responsibility.Infosys declined to comment saying it is speculation.
