Can Costco's 6% May Comparable Sales Fuel a Strong Q4 Start?

Costco reported a 6% increase in May comparable sales, excluding gasoline and foreign exchange impacts, signaling a positive start to fiscal Q4, with e-commerce sales surging 12%. The U.S. saw a 5.5% increase, while Canada and Other International regions rose 6.3% and 8.4%, respectively; overall net sales increased 6.8% year-over-year to $20.97 billion. While Costco's sales growth outpaces peers like Target (experiencing a 3.8% decline), the company's high forward P/E ratio of 52.14 compared to the industry's 33.53 suggests a premium valuation, and it faces potential headwinds from macro uncertainties and tariffs.

Analysis

Costco Wholesale Corporation (COST) reported a robust 6% increase in May comparable sales, excluding gasoline price fluctuations and foreign exchange impacts, signaling a positive commencement to its fourth quarter of fiscal 2025. This growth, supported by a significant 12% surge in e-commerce comparable sales and strong international performance with Canada at 6.3% and Other International regions at 8.4%, contributed to a 6.8% year-over-year rise in net sales to $20.97 billion. Although the May comparable sales figure represents a gradual deceleration from March's 9.1% and April's 6.7%, the overall trend remains positive, especially when contrasted with peers like Target Corporation (TGT), which saw a 3.8% decline in comparable sales. Dollar General (DG) posted a more modest 2.4% increase in same-store sales. Costco's stock has reflected this strength, rallying 10.7% year-to-date, outpacing the industry's 6.3% growth. However, this performance comes with a high valuation, as evidenced by a forward 12-month price-to-earnings ratio of 52.14, significantly above the industry average of 33.53, and a Zacks Value Score of D. Despite this premium, Zacks Consensus Estimates project an 8% year-over-year growth in sales and a 12% increase in earnings per share for the current fiscal year, though the company must navigate volatile macro headwinds and potential tariff complexities.

Key Decisions for Investors

• Investors should acknowledge Costco's strong sales momentum and positive earnings outlook, but carefully consider the stock's premium valuation, as indicated by its P/E ratio of 52.14 and Value Score of D, when making investment decisions.
• The consistent outperformance relative to peers and strength in e-commerce are positive indicators, however, monitoring for continued deceleration in comparable sales growth trends and the impact of external macro factors is advisable.
• Given the Zacks Rank #3 (Hold) and potential headwinds from macro uncertainties and tariffs, a balanced approach is warranted, weighing the company's solid operational execution against the elevated valuation and external risks.
