Walmart plans another leadership change as John Furner reshapes strategy

Walmart’s latest management shake-up reaches Sam’s Club, where Diana Marshall is set to leave after more than 20 years with the company. The move comes as John Furner, now president and CEO of Walmart Inc., continues to redraw the leadership map for a business that says it employs 2.1 million associates worldwide.

Marshall’s exit is not happening in isolation. Walmart named Furner to succeed Doug McMillon effective February 1, 2026, after McMillon retired on January 31 and stayed on the board through the next shareholders’ meeting to smooth the transition. On January 16, Walmart also shifted several top jobs, naming Latriece Watkins chief executive of Sam’s Club U.S., David Guggina chief executive of Walmart U.S., Chris Nicholas chief executive of Walmart International and Seth Dallaire chief growth officer. For store and club leaders, that means the chain of command above them has been moving quickly while Furner settles in.

Marshall had been executive vice president and chief experience officer at Sam’s Club, a role Walmart created in 2024 to oversee membership, product design, marketing and advertising. That put her close to the parts of the club business that members notice first, including how the clubs are presented, how the value proposition is marketed and how the membership experience is packaged. Sam’s Club now has more than 600 clubs across the United States and Puerto Rico and reported $90.2 billion in revenue for the fiscal year ending January 31, 2024, so leadership changes there reach a major operating arm, not a side unit.

For associates on the floor, the practical question is not who has the title but which projects get pushed forward. The company has already been rolling out AI-powered exit technology at more than 120 locations and has said Member’s Mark food and beverage products reached a 100% “Made Without” milestone after removing more than 40 unwanted ingredients and synthetic colors. Those kinds of initiatives can affect how clubs handle exit checks, product standards, merchandising and the pace at which new systems land in daily work.

Marshall’s departure also follows other recent exits in the Sam’s Club and U.S. store ranks, including the retirement of COO Tom Ward and the departure of Walmart EVP of U.S. store operations Cedric Clark. Taken together, the moves suggest Furner is still lining up the executives who will carry out his plan, with Sam’s Club, store operations and customer-experience functions all in play.

The open question for associates is whether the reset brings steadier support or more change. In a company this large, even a single departure in the right seat can alter which pilots scale, which teams get resources and how fast the home office’ priorities show up in clubs and stores.
