- Investment Return Analysis: A $1,000 investment in Costco ten years ago would be worth $6,500 today, or $7,725 with reinvested dividends, showcasing its strong performance against the S&P 500 index.
- Sustained Growth Drivers: From fiscal 2020 to 2025, Costco's revenue and EPS grew at CAGRs of 10.5% and 15.1%, respectively, with warehouse count increasing from 795 to 914 and cardholders rising from 105.5 million to 140.6 million, demonstrating robust market expansion capabilities.
- Membership Renewal Challenges: Despite raising membership fees for the first time in 2024, Costco's global renewal rate dipped to 89.7% in the first half of fiscal 2026, primarily due to younger digitally signed members being more likely to cancel.
- Future Growth Expectations: Analysts forecast Costco's revenue and EPS to grow at CAGRs of 8% and 11% from 2025 to 2028, but with a current P/E ratio of 49, the stock may only rise 34% over the next decade.
