For the past few years, Walmart (NYSE:WMT) has focused on digital growth, improved delivery options, and building out its omnichannel capacity. As that has happened, the company has also quietly been working on remodeling its stores. “Over the past few years, Walmart has focused on remodeling its U.S. stores to give customers an updated shopping experience, but the amount of work that goes into these remodels is staggering,” wrote Walmart corporate affairs executive Matt Smith on the company’s blog. “Right now, Walmart real estate is completing about 500 full store remodels each year along with thousands of special projects in stores across the country.” This has not gotten the same attention as Target‘s effort to remodel its stores, but it’s equally important. Walmart’s extensive brick-and-mortar portfolio gives it an edge that pure-digital rivals can’t compete with. Improving those stores builds on that advantage.
