Walmart has announced significant leadership changes, with David Guggina set to become the new CEO of Walmart U.S., the company's largest and most crucial division. Guggina, who has held various key roles including executive vice president of supply chain operations, previously served as the chief e-commerce officer for Walmart U.S. This promotion is effective February 1, 2026.

These executive adjustments are designed to maintain Walmart's strong growth trajectory and industry leadership. Chris Nicholas has been appointed as the CEO of the Walmart International division. Additionally, Seth Dallaire's responsibilities as chief growth officer will now extend globally. All these transitions are scheduled to take place on February 1, 2026.
