# COST Earnings Preview: September 24, 2026 Report
Costco Wholesale Corporation (COST) will report its quarterly earnings on September 24, 2026, after market close. Wall Street analysts have set the consensus EPS estimate at $6.67, a figure that will be closely scrutinized given COST's current trading price of $896.40. This earnings report comes at a crucial time as investors evaluate the wholesale giant's ability to maintain its growth trajectory in an evolving retail landscape.
Key Metrics Wall Street Will Watch
ā¢ Membership Fee Revenue Growth - Wall Street will focus on membership renewal rates and any potential fee increases, as this high-margin revenue stream is critical to COST's profitability model
ā¢ Comparable Store Sales (Comps) - Analysts expect strong same-store sales growth, particularly in fresh foods and e-commerce, as indicators of market share gains and customer loyalty
ā¢ Operating Margin Expansion - Despite inflationary pressures, investors will look for COST's ability to maintain or improve margins through operational efficiency and scale advantages
Bull Case vs Bear Case
Bull Case: COST's defensive business model thrives during economic uncertainty as consumers trade down to value retailers. The company's strong balance sheet, growing membership base, and expansion into new markets position it for continued outperformance. Recent investments in technology and supply chain optimization should drive margin expansion while maintaining competitive pricing.
Bear Case: Rising interest rates and consumer spending pullbacks could pressure discretionary purchases and bulk buying behavior. Increased competition from Amazon and other retailers, combined with wage inflation and supply chain costs, may compress margins. The premium valuation leaves little room for disappointment if growth momentum slows.
AI Positioning Ahead of Earnings
Our AI analysis suggests a cautiously optimistic stance heading into COST's September 24 report. The model weighs COST's historically resilient membership model and defensive characteristics against current macroeconomic headwinds. While the $6.67 EPS estimate appears achievable based on recent trends, the focus should be on forward guidance and management commentary about consumer behavior shifts. The AI recommends monitoring pre-earnings options activity and volume patterns for additional sentiment clues.
Historical Earnings Performance
Historically, COST has demonstrated relatively stable earnings reactions, with average post-earnings moves of 3-5% in either direction. The stock tends to perform well when membership growth exceeds expectations and management provides optimistic forward guidance. However, any signs of slowing comparable store sales or margin pressure have triggered more significant selloffs. Over the past eight quarters, COST has beaten EPS estimates 75% of the time, suggesting a solid track record of execution and conservative guidance from management.
