Americas’ top 20 enterprise CIOs of 2020

Sam Forsdick — September 2020

Who are the most powerful digital tech leaders across North and South America? Our ranking profiles the CIOs and heads of tech at the continents’ largest companies.


See our exclusive infographic: The characteristics of America’s top 20 business CIOs

This year has been a challenging one for many tech leaders at the top-performing US companies. They have had to contend with the additional complexities brought on by the global pandemic and economic and geopolitical upheaval, on top of the usual challenges of fulfilling increasingly IT-driven business functions. Our annual ranking of the top 20 heads of global IT identifies those who have helped navigate their organizations through these changes.

Two of the longest-serving CIOs — Clay Johnson and Mike Brown, of Walmart and ExxonMobil respectively — have moved into new roles since our 2019 round-up, which means that two new faces top our list of the region’s most powerful CIOs. Suresh Kumar, CTO and CDO of Walmart (there is no longer a CIO at the world’s largest company), and Bill Keillor, of ExxonMobil, are joined by new tech leads at McKesson, AmerisourceBergen, Walgreens Boots Alliance, Marathon Petroleum and Kroger.

Marathon Petroleum is one of three new entrants to the list, having seen its revenue increase by almost a third in 2019 as a result of its acquisition of rival Andeavor. Other new entrants are Microsoft and UnitedHealth Group.

Although Amazon and Apple continue to rank as two of the most powerful companies in the world, in terms of annual revenue, they both remain evasive about revealing any single head of their internal IT operations.

Women continue to be underrepresented at the top of the industry, with only 2 of the 20 largest companies in the US naming a female CIO. While Kathy McElligot was replaced by Nancy Flores in the top IT position at healthcare company McKesson, Pam Parisian’s departure from AT&T has left one fewer women in the top 20 list.

In terms of sectors, healthcare and pharmaceutical technology feature most prominently, taking up 6 of the top 20 places. Telecoms and retail CIOs also continue to perform well and, despite the recent slump in the price of oil, three US oil and gas companies also make this year’s list.
