Costco Wholesale Corp Reports Robust Q3 2025 Financial Results

Costco has reported an impressive 8% increase in net sales, reaching $61.965 billion for the third quarter of 2025. This growth is attributed to both a rise in comparable sales and the strategic opening of 29 new warehouses since the same period last year. Furthermore, membership fee revenue saw a notable 10% increase, totaling $1.24 billion, primarily driven by new member sign-ups and fee adjustments.

The company experienced a significant rise in net income, which reached $1.903 billion for the quarter—an increase from $1.68 billion reported in Q3 2024. This translates to earnings of $4.28 per diluted share, showcasing Costco's ability to leverage its operational efficiencies and customer loyalty effectively.

Costco's net sales for the third quarter increased by $4.573 billion compared to the previous year. The first thirty-six weeks of 2025 also saw a $14.04 billion increase in sales. Comparable sales rose by 6%, driven by a 5% increase in shopping frequency, although this was partially offset by lower gasoline prices, which negatively impacted net sales by $642 million in Q3.

Membership fees continue to be a robust revenue stream for Costco, with a 10% increase in revenue for the third quarter. The company reported impressive membership renewal rates of 92.7% in the U.S. and Canada, with a global rate of 90.2%. The slight decline in renewal rates can be attributed to increased online sign-ups, which historically have lower retention rates.

Costco's gross margin percentage improved by 41 basis points in Q3, reflecting strength in core merchandise categories, particularly fresh foods and sundries. However, the company faced challenges from higher merchandise costs and LIFO charges, which impacted margins.

Selling, General and Administrative (SG&A) expenses increased as a percentage of net sales by 20 basis points due to rising warehouse operation costs and employee wages. The company is making ongoing investments in employee compensation, which have contributed to this rise.

Costco’s aggressive expansion strategy remains evident with the opening of 17 new warehouses within the first thirty-six weeks of 2025, with ten more planned by year-end. The company’s capital expenditures for this period totaled $3.532 billion, with expectations to exceed $5 billion for the full fiscal year.

As of May 11, 2025, Costco reported cash and cash equivalents of $14.85 billion, demonstrating solid liquidity. The company generated $3.46 billion from operating activities, further solidifying its financial foundation, despite a net cash outflow of $748 million from financing activities primarily due to dividend payments and stock repurchases.

In line with its commitment to return value to shareholders, Costco's Board of Directors authorized a $4 billion share repurchase program in January 2023. To date, the company has repurchased 658,000 shares of common stock under this program.

Costco Wholesale Corp's Q3 2025 results reflect a robust growth trajectory, bolstered by strategic warehouse openings, strong membership retention, and effective management of operational costs. The company's focus on providing value to its members continues to enhance its competitive edge in the retail marketplace. With a strong balance sheet and ongoing expansion plans, Costco appears well-positioned for sustained growth in the coming quarters.
