J.B. Hunt warns of 5%‑10% Q3 earnings hit as diesel prices surge
Last week, J.B. Hunt warned that rising fuel and driver costs could cut its third‑quarter earnings by 5% to 10%. Retail diesel prices climbed about 31% between July 5 and September 17, while wholesale prices rose more than twice as fast.
Because many large carriers buy fuel at wholesale rates and pass costs to customers via retail‑based fuel surcharges, a narrowing wholesale‑retail spread erodes their margin buffer. The fuel spread has fallen to just above $1 per gallon since early July, down from roughly $1.25 averaged from 2022 through March and above $1.50 from April to July. Smaller fleets that lack wholesale purchasing power face a different squeeze, with retail diesel up about 24% over the past three months while spot rates have slipped roughly 6%. In a competitive market, smaller fleets struggle to pass higher retail diesel costs through spot rates, limiting their ability to raise prices.
Most of J.B. Hunt’s dedicated and intermodal contracts were set before the market flip in late 2025 and early 2026, leaving them exposed to operating‑cost inflation. The market viewed the warning as a giveback after a potentially bloated second quarter, not a long‑term threat.
