Walmart U.S. COO Kieran Shanahan Exits After 30 Years as Leadership Shake-Up Continues

Quick Facts

Kieran Shanahan, 45, is stepping down as COO of Walmart U.S. after nearly 30 years with the company, effective this week.
Kyle Kinnard, 47, formerly COO of Walmart International, takes over the role immediately.
Shanahan is the third senior Walmart executive to depart in the past two months, following Tom Ward and Cedric Clark.

Walmart U.S. chief operating officer Kieran Shanahan is leaving the company after a career spanning nearly three decades. Kyle Kinnard, who served as COO of Walmart International, assumed the executive vice president and COO role for Walmart U.S. effective immediately, according to an internal memo first reported by The Wall Street Journal.

Shanahan, once considered a candidate for a future CEO role at Walmart, will remain with the company in an advisory capacity to Walmart U.S. CEO David Guggina through the end of the fiscal year on January 31, 2027.

The departure marks a significant moment in a broader executive reshaping under CEO John Furner, who took the helm of Walmart Inc. on February 1, 2026, succeeding Doug McMillon. Shanahan is the third top executive to exit in roughly two months. Sam’s Club COO Tom Ward retired in May, and Cedric Clark, executive vice president of U.S. store operations, also departed that same month. The three departing executives represent a combined 70 years of retail experience at Walmart.

Shanahan joined Walmart early in his career and spent eight years at Asda, Walmart’s former U.K. grocery chain. He transferred to the U.S. in 2014 under then-CEO Greg Foran and played a key role in building out Walmart’s online grocery operation. He later served as chief merchandising officer, spent a year overseeing growth at Sam’s Club, and held a regional CEO post within Walmart International before becoming COO of Walmart U.S. in August 2023.

Kinnard’s path into Walmart began in 2000 as an hourly associate at Sam’s Club in Springdale, Arkansas. Over 25 years, he held leadership roles across operations, merchandising, and healthcare in the U.S. before moving into international operations. He holds a marketing degree from the University of Arkansas and an MBA from John Brown University. Kinnard will continue serving as chair on the board for Walmart de México y Centroamérica.

In the memo, Guggina and Walmart International CEO Chris Nicholas wrote: “Kyle’s proven track record is matched only by his dedication to servant leadership and his passion for coaching the next generation of Walmart leaders.”

Walmart also announced Friday that Juan Galarraga was promoted to oversee the company’s international businesses in Latin America.

The leadership changes align with a technology-focused strategy Furner is pushing across the business. In January 2026, Furner said the restructuring was tied directly to AI adoption across Walmart’s platforms. “As AI rapidly reshapes retail, we are centralizing our platforms to accelerate shared capabilities, freeing up our operating segments to be more focused on and closer to our customers and members,” he said at the time.

Walmart reported fiscal year 2026 revenue of $713 billion and employs approximately 2.1 million people worldwide. The company serves roughly 280 million customers and members each week across more than 10,900 stores in 19 countries. In May, Walmart also eliminated 1,000 roles from its workforce as part of a broader organizational consolidation.

Walmart has simultaneously ramped up brick-and-mortar investment. U.S. spending on new store construction and relocations more than tripled in fiscal year 2026 compared to 2024, following a 500% increase the prior year. The company has also been cutting prices on consumer staples including meat, chips, and soda ahead of summer.
