Less than half of CEOs from the top 100 companies included in the Fortune 500 list have an MBA.
Four CEOs running companies included in the top 100 Fortune 500 companies attended The Wharton School at University of Pennsylvania.
And then there's Greg L. Armstrong, CEO of Plains GP Holdings, which owns and operates natural gas storage facilities and manages other businesses. Like Bezos, Armstrong does not have an MBA, yet his company landed one of the coveted spots on the Fortune 500 list: No. 70.
Of the 100 companies leading the newest Fortune 500 list, released on June 2, less than half of their CEOs had an MBA. U.S. News looked at the educational background of the CEOs. School data for one CEO could not be confirmed.
"To actually get in the C-suite, it’s a little bit like winning the lottery. Especially for a Fortune 100 company, " says David G. Rohlander, author of "The CEO Code: Create a Great Company and Inspire People to Greatness with Practical Advice from an Experienced Executive." A pattern of successfully accomplishing your goals and an optimistic mindset are two of the most important traits for becoming a CEO, he says.
While business school may not be necessary for landing these kind of leadership roles, it can help. "It's going to give you a better capability of thinking, " says Rohlander, who received his MBA in finance from the business school at California State University—Fullerton, now known as Mihaylo College of Business and Economics. And going to a prestigious school may help with advancing career goals, he believes, because of the networking opportunities.
On the Fortune 500 list, which ranks U.S.-based companies with the highest revenue, many of the CEOs who received an MBA attended business schools ranked within the top 20. Eight attended Harvard Business School and four attended The Wharton School at University of Pennsylvania. Two attended the Booth School of Business at University of Chicago. Fewer than a dozen graduated from law school.
This year's Fortune 100 list included nine women, four of whom received an MBA.
