Trucking companies rarely get to choose the moment fuel prices spike, and September 2026 has been a particularly bad one. National diesel prices linked to the war in Iran hit a record $6.31 a gallon, up more than 70% year over year, with California prices already above $8. J.B. Hunt Transport Services, Inc. (NASDAQ:JBHT) felt that shock directly: its shares fell 13% on September 16, the worst day the company has had since it went public in 1983. This happened after management warned that earnings could drop 5% to 10% quarter over quarter. Finance chief Brad Delco described the swings as some of the most radical and abnormal he has seen.
For investors, the case comes down to timing rather than the direction of the core business. J.B. Hunt has tools, fuel surcharges and an intermodal network, built for exactly this kind of shock. But those tools work with a lag. Whether the current quarter turns out to be a one-time hit or the start of a longer squeeze depends on how quickly diesel prices stabilize and how much of the damage the company can actually recover.

Bull Case
J.B. Hunt Transport Services, Inc. (NASDAQ:JBHT) uses fuel surcharges to recover higher diesel costs, but those formulas adjust with a lag. That timing mismatch hurts near-term earnings when prices rise suddenly. Yet it also creates a recovery mechanism if diesel stabilizes and surcharge revenue catches up with the company’s actual fuel expense.
Higher diesel prices can also make J.B. Hunt’s rail-and-truck intermodal service more attractive than long-haul trucking. The company reported 10% intermodal volume growth and a 58% increase in intermodal operating income in the second quarter, and it linked stronger demand partly to customers seeking relief from fuel costs. Constant freight conversion could help volume and network efficiency even as fuel raises near-term expenses.
J.B. Hunt expects about $25 million more in driver-related spending in the third quarter than in the second as it recruits and trains drivers, and that spending will hurt near-term profit. But it could help the firm serve stronger demand. If more shipments make fuller use of those drivers and its intermodal network, revenue growth could spread those costs across more loads and help an earnings recovery.
Bear Case
Management expects third-quarter earnings to fall 5% to 10% from the second quarter as higher fuel, driver, and claims costs hit at the same time. Direct guidance makes the pressure more than a broad industry concern. It also shows that J.B. Hunt Transport Services, Inc. (NASDAQ:JBHT) cannot pass every cost increase to customers quickly enough to protect near-term margins.
Record diesel prices create a particularly difficult cash-flow mismatch because J.B. Hunt pays the higher cost immediately while surcharge formulas respond later. Price swings would repeatedly reset that gap and extend the earnings pressure beyond one quarter. It can also make management’s outlook less reliable.
Fuel does not explain the entire earnings warning. J.B. Hunt also expects roughly $25 million of additional driver costs and faces higher claims as medical expenses rise, so falling diesel prices would remove only part of the pressure. Persistent labor and insurance costs could keep margins weak after surcharge revenue catches up.
Hedge Fund Sentiment
J.B. Hunt Transport Services, Inc. (NASDAQ:JBHT)’s hedge fund count fell to 43 in the second quarter of 2026 from 45 in the first, even as position value rose to $2.63 billion from $2.02 billion, according to Insider Monkey’s database. Knight-Swift, a fellow trucking and intermodal carrier facing the same fuel cost pressure, saw its holder count grow to 69 from 53, with position value climbing to $2.36 billion from $1.83 billion.
Conclusion
J.B. Hunt can handle a temporary rise in fuel costs due to its surcharge system and intermodal network. However, management has already warned that fuel prices, driver wages, and insurance claims will hurt earnings.
Investors need to watch how fast J.B. Hunt collects these fuel surcharges and whether shipping volumes rise or fall. Steady diesel prices will quickly fix the company’s profit margins. On the other hand, erratic fuel prices will keep squeezing profits and turn a single bad quarter into a long-term earnings trouble spot.
