The technology company said Tuesday that Rometty, 55, will take on the expanded role Oct. 1. Palmisano, 61, will serve as a senior adviser until he retires in December.
Rometty, the company’s former sales and marketing chief, became IBM Corp.’s first female CEO in January. Joining the Armonk, N.Y.-based company in 1981 as an engineer, Rometty later was instrumental in the formation of IBM’s business services division, including overseeing the $3.5 billion purchase of PricewaterhouseCoopers’ consulting business in 2002.
IBM has sustained a nearly decade-long streak of earnings growth as it shook off the economic jitters that have undercut several other technology companies.
