Costco Wholesale Corp. reported April sales of $10.81 billion, up 12.1% from 9.56 billion last year. The warehouse retailer said the four weeks benefited from an extra day due to the Easter calendar shift. Same-store sales rose 7.3%, getting a 1%-to-1.5% boost from the Easter change. E-commerce sales rose 43.1% for the month. Cowen analysts "remain impressed by digital and physical momentum," they wrote in a note. "We believe Costco is well positioned to continue delivering double-digit earnings growth over the near-to-medium term driven by square footage growth, membership revenue growth, and industry leading physical store traffic growth," Cowen said. "Costco's higher income customer base (average household income of ~$73k) is faring better economically than low- to middle-income consumers, who continue to struggle with wage growth." Cowen rates Costco shares outperform with a $214 price target. Susquehanna Financial Group maintained its positive stock rating based on Costco's sales growth despite the competition from omnichannel retailers, as evidenced by the same-store sales growth. Susquehanna has a $230 price target on Costco shares. Costco stock is up 0.8% in Thursday premarket trading, and up 5% for the year to date. The S&P 500 index is up about 1% for the period.
