Institutional context

International Business Machines Corporation (IBM) is a multinational technology company founded in 1911 as the Computing-Tabulating-Recording Company. It is among the longest-tenured Fortune 500 firms. From its founding through 2011 every Chief Executive Officer was male — a span of one hundred years.

Career path

Virginia Marie "Ginni" Rometty (born 1957) earned a BS in computer science and electrical engineering from Northwestern University. She joined IBM in 1981 as a systems engineer and rose through the global services and technology divisions over three decades. She served as Senior Vice President for Global Sales, Marketing, and Strategy from 2009 and was a leading internal candidate for the CEO succession from at least 2010.

Appointment

IBM announced her selection as President and CEO on 25 October 2011, effective 1 January 2012. She succeeded Sam Palmisano. She is the first woman CEO in IBM's history.

Tenure

Eight years and three months. Tenure included IBM's substantial restructuring around cloud and AI services (the Watson programme), the divestiture of low-margin hardware businesses, and the $34 billion acquisition of Red Hat in 2019. She left the CEO role on 1 April 2020 and was succeeded by Arvind Krishna.
