The financial performance of Costco Wholesale Corp. over the analyzed period is characterized by consistent growth in top-line revenue and a steady expansion of net income. Net sales exhibit a clear seasonal pattern, with peak values consistently occurring in the August and September quarters, while membership fees show a linear and stable upward trajectory.

Revenue and Gross Profit Trends
Net sales grew from 36.2 billion US dollars in November 2019 to 69.2 billion US dollars by May 2026. Gross margin expanded proportionally, maintaining a stable relationship with sales. Membership fees, a critical component of the revenue stream, increased from 804 million US dollars to 1.37 billion US dollars, indicating a growing member base and consistent pricing power.
Operational Efficiency and Expense Management
Selling, general, and administrative expenses increased as the company scaled, yet the growth of these expenses remained below the growth rate of operating income. Operating income rose from 1.06 billion US dollars in November 2019 to 2.82 billion US dollars in May 2026, reflecting operational leverage and efficient cost management.
Non-Operating Income and Financial Position
A significant increase is observed in interest income and other net income, which grew from 35 million US dollars in November 2019 to 155 million US dollars by May 2026. Other income and expenses also contributed positively to the pre-tax income in the later years of the period. Simultaneously, interest expenses remained remarkably stable, generally fluctuating between 32 million and 56 million US dollars, suggesting a strong balance sheet with low reliance on costly debt.
Bottom-Line Profitability
Net income attributable to Costco followed a strong upward trend, increasing from 844 million US dollars in November 2019 to 2.19 billion US dollars in May 2026. This growth was supported by the combination of rising membership fees, controlled operating expenses, and an increase in non-operating income.
