Industry Context

Costco's strong performance, particularly in e-commerce and membership growth, indicates its continued resilience and competitive advantage within the retail and warehouse club sector. The focus on digital enhancements and strategic international expansion aligns with broader industry trends of omnichannel retail and global market penetration, positioning the company well against competitors in a dynamic economic environment.

Comparison to Industry Standards

• Costco's 6.4% adjusted comparable sales growth in Q4 and 7.6% for the fiscal year generally outperforms many traditional retailers, often facing slower growth or declines. For example, many department stores or general merchandise retailers might see low single-digit or even negative comparable sales.
• The 13.5% adjusted e-commerce comparable sales growth in Q4 and 16.1% for the fiscal year is competitive with leading e-commerce players and significantly higher than the average for brick-and-mortar retailers transitioning to online sales.
• A worldwide membership renewal rate of 89.8% and US/Canada rate of 92.3% is exceptionally high, indicating strong customer loyalty and value proposition, often surpassing subscription-based services in other industries.
• The expansion of 9 new warehouses in Q4 and a projected 30 new warehouses in FY26 demonstrates aggressive growth, contrasting with some competitors who are rationalizing their physical footprints.

Stakeholder Impact

• Shareholders: Positive impact due to strong financial performance, increased net income, and EPS growth, potentially leading to higher stock valuation and dividends.
• Customers: Positive impact through continued warehouse expansion, enhanced e-commerce experience, and introduction of new Kirkland Signature items, improving accessibility and value.
• Employees: Positive impact from company growth and expansion, potentially leading to job creation and stability.
• Suppliers: Continued strong business relationships due to Costco's robust sales volume and expansion.

Next Steps

• A conference call to discuss these results is scheduled for September 25, 2025, at 2:00 p.m. (PT).
• Continue warehouse expansion, with an estimated total of 944 warehouses by the end of fiscal year 2026.
