Breaking down geographic contributions, the 'Other International' segment led with a 10.9% comparable sales increase, followed by Canada at 6.7%, and the U.S. at 4.7%. Adjusted for gasoline prices and foreign exchange effects, the growth rates are even stronger—7.9% in Canada and 8.2% internationally—signaling resilient demand across regions.

E-commerce growth of 11.5% further amplifies the company’s omnichannel strength, reflecting consumers' increasing preference for digital bulk shopping. This complements physical store performance and reinforces Costco’s adaptability in a shifting retail landscape.

Drivers Behind the Sales Surge#

The June sales acceleration stems from a blend of strategic and market-driven factors. Chief among them is Costco's focus on its Kirkland private-label brand, which offers high-margin products appealing to cost-conscious shoppers. This strategy boosts basket sizes and supports margin stability.

Inflationary pressures have encouraged consumers to consolidate purchases at value retailers, with Costco's membership model incentivizing loyalty and repeat spending. Seasonal promotions, including summer and back-to-school campaigns, also played a crucial role in driving traffic and sales volumes.

The international expansion efforts and enhanced e-commerce capabilities have diversified revenue streams and reduced dependence on any single market segment, enhancing overall business resilience.

Financial Performance and Profitability Metrics#

Costco's fiscal year 2024 financial results, reported in October 2024, provide a solid foundation for understanding the company’s profitability amid growth. Revenue reached $254.45 billion, a +5.02% increase over FY 2023's $242.29 billion. Net income rose +17.09% to $7.37 billion, reflecting operational leverage and cost management effectiveness.

Gross profit margin improved to 12.61% from 12.26% a year earlier, supported by the private-label product mix and efficient sourcing. Operating income margin increased to 3.65%, and net margin reached 2.9%, both showing steady improvement and reflecting Costco’s disciplined expense control.

Key profitability ratios include a return on equity (ROE) of 31.13% and a return on invested capital (ROIC) of 20.02%, underscoring strong capital efficiency and shareholder value creation.
