Old Dominion Freight Line Diesel Fuel Gallons Consumed (YoY %) by Quarter

Old Dominion Freight Line Diesel Fuel Gallons Consumed (YoY %): -5.2% in Q2 2026, up 2.8 pts from a year earlier.

“Operating supplies and expenses increased $35.2 million, or 24.7% and $32.1 million, or 11.0%, in the second quarter and first six months of 2026, respectively, as compared to the same periods of 2025 primarily due to an increase in our costs for diesel fuel used in our vehicles that was partially offset by lower maintenance and repair costs for our fleet. The cost of diesel fuel, excluding fuel taxes, represents the largest component of operating supplies and expenses, and can vary based on both the average price per gallon and consumption. Our average cost per gallon of diesel fuel increased 70.5% and 41.2% in the second quarter and first six months of 2026, respectively, as compared to the same periods of 2025. We do not use diesel fuel hedging instruments; therefore, our costs are subject to market price fluctuations. Our gallons consumed decreased 5.2% and 7.3% in the second quarter and first six months of 2026, respectively, as compared to the same periods of 2025, primarily due to a decrease in miles driven.”
