- Significant Membership Growth: Costco's paid membership surged from 44.6 million to 82.1 million, indicating enhanced customer loyalty and market appeal, which lays a solid foundation for future revenue growth.
- Continued Warehouse Expansion: The global warehouse count increased from 686 to 924, demonstrating strong international expansion capabilities, although the future target of only 28 new warehouses may limit growth potential.
- Stock Price Discrepancy: Despite a cumulative earnings per share growth of 258% since fiscal 2015, the stock's total return reached 734%, reflecting a high premium on earnings that may face valuation risks in the future.
- Cautious Future Growth Expectations: Analysts forecast a 12% earnings growth this year and an annual growth of 9.6% thereafter, suggesting that investors should temper their expectations for the next decade, anticipating more modest returns compared to previous years.

- Stand-Alone Gas Station Initiative: Costco plans to launch its first stand-alone gas station in Mission Viejo, California, in June with 40 pumps, aimed at alleviating congestion around its current store locations and enhancing customer experience.
- Exclusive Member Benefits: The new gas stations will be accessible only to members who pay an annual fee of $65 or $130, likely attracting more consumers seeking gas prices that are $0.10 to $0.30 below the U.S. average, thereby increasing membership and company revenue.
- Strategic Value Enhancement: As of the end of fiscal year 2025, Costco operated 747 gas stations worldwide, contributing 10% to the company's net revenue, and the introduction of new stations will further solidify its pricing authority and competitive edge in the market.
- Positive Market Reaction: Costco's stock has risen 15% this year, and although it trades at 48 times forward earnings, the strategy of stand-alone gas stations is viewed positively by shareholders, boosting investor confidence amid geopolitical tensions and recession concerns.
