John Furner, the relatively new CEO of Walmart U.S., is a Walmart lifer at 45 years old. He has logged 26 years at the retail giant. Walmart is one of the darlings of Wall Street. Mark Ryski, CEO of HeadCount Corp., says Walmart’s impressive results and pursuit of technology and innovation will likely continue under Furner’s leadership. “The greatest challenges Furner faces will be to build on and advance an organization with the size and success of Walmart and continue to battle against Amazon at the same time. I also think that Furner’s history within the organization, starting as an hourly associate and working his way up, gives him a unique perspective on all aspects of the business.”
