Truckload Rate Gains Erased by 72% Diesel Surge, Carrier Margins Stall

Truckload carriers are posting double-digit revenue growth this earnings season, but a 72% year-over-year jump in diesel prices is consuming most of those gains before they reach the bottom line, according to results from J.B. Hunt, Werner and Heartland Express. Contract rates are up 18% year over year but will need to keep climbing for carriers to hold margin. J.B. Hunt's third-quarter operating revenue climbed 24% on stronger pricing, an 8% increase in intermodal loads and higher broker volumes, yet net earnings rose only 1% as driver expenses, fuel and insurance claims absorbed nearly all the gain. Werner flagged roughly $0.18 per share in cumulative cost headwinds tied to fuel and driver recruitment. Heartland posted an operating ratio of 98.7, with CEO Mike Gerden citing rising fuel and maintenance costs; the company is looking toward 2027 for contract rate increases sufficient to offset the pressure. Diesel averaged $6.37 per gallon in October versus $3.70 a year ago and peaked near $6.53 in late September. Intermodal is a relative bright spot: the Sonar Intermodal Cost Savings Index shows a 30% road-to-rail savings benefit, though drayage capacity scarcity limits conversion. The Sonar STRI stands at 13.5%, still 5.6 percentage points above year-ago levels.
