Walmart (WMT) stock reaches a record high intraday on Tuesday after the retailer reported better-than-expected fourth-quarter earnings results. E-commerce sales jumped 23% year-over-year, beating estimates on both revenue and earnings year-over-year. Walmart CFO John David Rainey joins Yahoo Finance Live to discuss the drivers behind the strong performance. Rainey says holiday spending fueled sales, with "the two biggest sales days" occurring right before Christmas. Over the quarter, Walmart "gained share in almost every category," showing customers are increasingly shopping at Walmart as the company enhances how it serves them. Another headline for the big-box chain is its plans to acquire TV manufacturer Vizio (VZIO) for $2.3 billion, after Walmart's "fast-growing, high margin" advertising business grew by 33% in the past quarter. Rainey explains the deal will allow Walmart to "connect and serve customers in different ways" by leveraging data to improve experiences. While consumers show discretion around bigger purchases, Rainey says Walmart's "omnichannel retail model" with robust in-store and online distribution "is really resonating with customers" as they shop more frequently. As inflation persists, Walmart wants to provide value through lower prices, working with suppliers, and fine-tuning its own personal brands. However, Rainey notes "it's hard to generalize" where price pressures occur across categories.
