Convenience store same-store grocery and merchandise sales measure category sales growth at locations eligible for Casey's same-store population.

Casey's reported 3.9% grocery and merchandise same-store sales growth for fiscal 2026.

Total category sales grew about 10.1%

Grocery and merchandise revenue increased from $4.144 billion to $4.564 billion, about 10.1%.

The roughly 6.2-percentage-point gap versus same-store growth reflects footprint growth and other differences between total and comparable-store measures.

Grocery same-store growth trailed prepared food by 1.3 points

Prepared-food same-store sales grew 5.2%, which was 1.3 points faster than grocery and merchandise.

That spread helps explain why mix can shift toward higher-margin food even when grocery remains the larger inside category.

Same-store growth is not total category growth

Casey's eligibility rules exclude newly constructed and acquired stores until they enter the comparison base.

Use Convenience Store Grocery and Merchandise Sales for total category dollars.

Inside sales mix and category contribution
Inside sales combine grocery and general merchandise with prepared food and dispensed beverages. Category sales and category contribution margins determine how mix shifts change the economics of the inside-store basket.

Fuel throughput and per-gallon economics
Retail fuel economics depend on physical gallons and contribution per gallon. Average gallons per mature store and same-store gallon growth help separate unit productivity from footprint expansion.
