Costco has demonstrated resilient performance through economic cycles, achieving positive same-store sales growth for five consecutive years. The wholesaler’s membership base has expanded from 105 million in fiscal 2021 to over 125 million in fiscal 2025, contributing to a compound annual revenue growth rate of 9.8% over that period. Operating margins have held steady around 3.2%, reflecting the company’s scale advantage and tight cost controls. With free cash flow surpassing $7.5 billion in the latest fiscal year, Costco is well positioned to reinvest in new warehouse openings—adding 30 net locations in fiscal 2025—and to sustain dividend increases, which have grown at a 15% annualized rate over the past decade. These factors underline how disciplined execution and a loyal membership model could compound shareholder returns over the long term.

When compared with Home Depot, Costco stands out for its consistent sales momentum. Over the last five years, Costco’s same-store sales have risen by an average of 6.4% annually, despite consumer headwinds in housing and discretionary categories. Home Depot, by contrast, experienced a 1.2% decline in same-store sales in its most recent quarter as housing affordability pressures weighed on renovation spending. On valuation metrics, Costco trades at a price-to-earnings ratio of 49.6, reflecting investor willingness to pay a premium for recurring membership fees and stable cash flow. Home Depot’s P/E of 25.4 suggests greater sensitivity to economic cycles but offers a lower entry point. Investors seeking high-quality growth may favor Costco’s secular tailwinds, while those prioritizing valuation might lean toward Home Depot’s current discount.
