Quarterly Results

Gross margin percentage increased 41 basis points. Excluding the impact of gasoline price deflation on net sales, gross margin percentage increased to 11.13%, 29 basis points. This increase was positively impacted by 27 basis points in our core merchandise categories, primarily in fresh foods and foods and sundries and 27 basis points in warehouse ancillary and other businesses, primarily gasoline and e-commerce. Gross margin was negatively impacted by 23 basis points due to a LIFO charge for higher merchandise costs and two basis points for a one-time expense for increased employee vacation. Changes in foreign currencies relative to the U.S. dollar negatively impacted gross margin by approximately $80, compared to the third quarter of 2024, attributable to our Other International and Canadian operations.

The gross margin in core merchandise categories, when expressed as a percentage of core merchandise sales (rather than total net sales), increased 36 basis points. The increase was across all categories, most significantly fresh foods which benefited from sales leverage, higher productivity, and lower prices for certain commodities. This measure eliminates the impact of changes in sales penetration and gross margin from our warehouse ancillary and other businesses.
