Costco June sales boosted by e-commerce and international growth

Costco's June sales rose 8% year-over-year to $26.44 billion, driven by 11.5% e-commerce growth, international expansion, and 5.8% comparable sales gains. UBS analysts affirmed the results reflect continued excellent execution and ongoing market share gains, notably in non-discretionary categories. Strategic digital investments, including enhanced delivery and a new buy-now-pay-later offering, are cited as key growth drivers, underpinning expectations for continued customer penetration and a premium valuation.

Analysis

Costco reported a robust 8% year-over-year sales increase to $26.44 billion for June, underpinned by strong comparable sales growth of 5.8%. The performance was driven by significant momentum in its international segment, which saw comps jump 10.9%, and a surge in e-commerce sales, which grew 11.5%. Analyst commentary from UBS highlights this as evidence of continued market share gains, particularly in non-discretionary categories like Fresh Foods, which grew in the high single digits. While overall comparable sales growth is moderating as pandemic-era tailwinds from categories like gift cards and precious metals subside, this appears to be in line with market expectations. The company's strategic digital investments are a key factor, with growth attributed to SKU expansions, enhanced delivery logistics enabling 2-day service in many urban centers, and a new buy-now, pay-later partnership with Affirm. This partnership is expected to stimulate demand for big-ticket items, further accelerating e-commerce growth and deepening customer penetration. Despite the strong report, the stock was little changed, suggesting the market has already priced in this solid execution, which UBS believes warrants a premium valuation.

Key Decisions for Investors

• The strong sales data validates Costco's resilient business model and market share gains, supporting the bull case for holding the stock despite its premium valuation.
• Investors should monitor the performance of strategic initiatives, particularly the e-commerce platform and the new buy-now, pay-later offering, as these are positioned as the next key drivers for growth.
• The muted stock reaction suggests high expectations are already priced in, indicating that sustained outperformance is necessary to drive further significant share price appreciation from current levels.
