BENTONVILLE, Ark. — Wal­mart is merging its store and digital supply chain teams in the United States. The retailer says the move is a next step in its effort to create a seamless omnichannel shopping experience for its customers.

Greg Smith, executive vice president of supply chain at Walmart U.S., will lead the combined team, and will report to Greg Foran, president and chief executive officer of Walmart U.S., and Marc Lore, president and CEO of Walmart eCommerce U.S.

The move was announced in a memo from Walmart chief executive officer Doug McMillon.

“Greg has demonstrated his leadership ability and his capability to help shape the future of our omnichannel supply chain,” McMillon wrote.

Smith will head a supply chain leadership team composed of Mike Gray (Regional Distribution Network), Tim Cooper (Grocery Distribution Network), Alex Krueger (eCommerce Fulfillment Operations), Monique Picou (Flow, the Fashion, Imports and Reverse Logistics Networks), Cameron Geiger (Supply Chain Services), Justen Traweek (Central Operations Supply Chain), Mike Indresano (eCommerce Transportation), Tom Shortt (Inventory Management and Strategy eCommerce), David Guggina (Central Operations eCommerce), Jeff England (Strategy and Automation), Ken Braunbach (Inbound Transportation) and Jeff Hammonds (Fleet Operations).

Nate Faust, who has been leading e-commerce fulfillment for Walmart since joining the company as part of the Jet.com acquisition in 2016, will help with integration of the new leadership teams before moving to a new, yet-to-be-announced position at the company.

“Faust has led tremendous eCommerce fulfillment progress these past few years,” McMillon wrote. “He has built a strong team, and our customer metrics reflect the tangible improvements they’ve made. We’re on the right trajectory. Nate will support the integration of these teams before moving to a new opportunity we’ve identified, and we’re looking forward to sharing more about that with you soon.

“As we bring these teams together, we will also bring the Supply Chain People team together, with Kate Vukelich reporting to Steve Miller to support this integration and, ultimately, the optimization of the collective organization.”

Walmart is also merging its U.S. finance and e-commerce finance teams. That combined team will be led by Walmart U.S. chief financial officer Michael Dastugue.

Walmart will continue to maintain separate teams for its in-store and online merchandising operations.

“There are a few areas where we are choosing to maintain some structural separation to enable focus and speed, including our U.S. merchandising organization,” McMillon wrote. “Our eCommerce sales growth, improving customer metrics and progress on contribution profit are encouraging, and we want to keep that going.”

The company has reassigned Ashley Buchanan, who has been executive vice president and chief merchandising officer at Sam’s Club, to serve as CMO for U.S. eCommerce, reporting to Lore.
