Convenience store same-store fuel gallons measure period-over-period change in retail fuel gallons at locations eligible for Casey's same-store population.
Casey's reported 1.4% same-store fuel-gallon growth for fiscal 2026.
Total gallons grew much faster than same-store gallons
Total retail fuel gallons increased about 10.0%.
The 8.6-percentage-point gap shows that new and acquired stores contributed materially to chainwide volume growth.
Same-store fuel growth was the slowest of Casey's three operating comps
Prepared-food same-store sales grew 5.2% and grocery and merchandise same-store sales grew 3.9%.
Fuel gallons grew 1.4%, so mature-store physical fuel throughput lagged inside-sales growth.
Newly constructed and acquired stores are excluded until eligible
Casey's same-store definition removes newly constructed and acquired stores until they have been open for each full comparison period.
Use Convenience Store Fuel Gallons Sold for total physical volume and this metric for the mature-store comparison.
