Exhibit 99.1

FOR IMMEDIATE RELEASE

J.B. HUNT TRANSPORT SERVICES, INC. REPORTS U.S. GAAP REVENUES, NET EARNINGS AND EARNINGS PER SHARE FOR THE SECOND QUARTER 2026

LOWELL, Ark., July 15, 2026 — J.B. Hunt Transport Services, Inc. (NASDAQ: JBHT) announced second quarter 2026 U.S. GAAP (United States Generally Accepted Accounting Principles) net earnings of $181.0 million, or diluted earnings per share of $1.91 versus second quarter 2025 net earnings of $128.6 million, or $1.31 per diluted share.

“I’m grateful for our people and their continued focus on delivering operational excellence around service, safety and cost discipline in this dynamic environment,” said Shelley Simpson, president and CEO. “Our second quarter results reflect the strength of executing our strategy, as we leveraged our investments in our people, technology, and capacity to drive growth and improve profitability. As market conditions continue to evolve, we remain focused on creating long-term value for our shareholders, delivering valuable solutions to our customers while maintaining discipline around returns on our capital.”

Total operating revenue for the current quarter was $3.50 billion compared with $2.93 billion for the second quarter 2025, an increase of 19%. Current quarter total operating revenue, excluding fuel surcharge revenue, increased 11% versus the second quarter 2025. The increase in revenue, excluding fuel surcharge revenue, was primarily driven by increased load volumes in Intermodal (JBI), Integrated Capacity Solutions (ICS) and Truckload (JBT), higher revenue per load in JBI, ICS and JBT and increased productivity in Dedicated Contract Services® (DCS®), partially offset by a 14% decline in Final Mile Services (FMS) stops.

Operating income for the current quarter increased 32% to $259.5 million versus $197.3 million for the second quarter 2025. The increase in operating income was primarily driven by higher revenue, improved productivity across the business, continued execution on our initiative to remove structural cost, lower group medical claims and lower facility rental and equipment storage expenses. These were partially offset by higher purchase transportation cost, particularly in our ICS and JBT segments and higher equipment-related expenses. Consolidated operating income as a percentage of gross revenue increased year-over-year as a result of the previously mentioned items, partially offset by higher fuel expense as a percentage of gross revenue.

Net interest expense for the current quarter decreased approximately 21% from the second quarter 2025 due to a lower average consolidated debt balance partially offset by a modestly higher average interest rate.

The effective income tax rate was 25.4% in the current quarter compared to 26.9% in the second quarter 2025. We now expect our 2026 annual tax rate to be between 24.0% and 24.5%.

Segment Information:

Intermodal (JBI)

Intermodal volume increased 10% over the same period in 2025. Transcontinental network loads increased 5%, while Eastern network loads increased 16% compared to the second quarter 2025. Overall demand for our intermodal service increased throughout the quarter driven by the strong value proposition it presents to customers facing higher fuel prices and constrained driver and capacity availability in other transportation modes. Volume growth in our Eastern network continues to be strong, driven by conversion and overall service execution. Segment gross revenue increased 22% from the prior-year period driven by the 10% increase in volume and an 11% increase in gross revenue per load, resulting from higher fuel surcharge revenue, customer rates and changes in mix of freight. Revenue per load excluding fuel surcharge revenue increased 1%.

Operating income increased 58% compared to the second quarter 2025 primarily due to network efficiency resulting from strong volume growth, productivity improvements across the dray network, lower proportion of empty container moves and lower container storage expense. Continued execution on initiatives to lower our cost to serve also contributed to the improvement. These were partially offset by higher insurance premium and claims expense and higher professional driver personnel expense.

Dedicated Contract Services (DCS)

DCS revenue increased 9% during the quarter compared to the same period 2025 driven by a 9% increase in productivity (revenue per truck per week) as average trucks were approximately flat versus the prior-year period. Productivity excluding fuel surcharge revenue increased 2% from the prior-year period due to contracted indexed-based price escalators. On a net basis, there were 5 additional revenue-producing trucks in the fleet by the end of the quarter compared to the prior-year period and approximately 140 more versus the end of the first quarter 2026. Customer retention rates have improved to approximately 96%.

Operating income increased 9% from the prior-year period. The increase was driven by the higher revenue, lower group medical claims expense and continued progress on the initiative to lower our cost to serve. These were partially offset by higher insurance premium and equipment-related expenses and higher new business onboarding expenses compared to the prior year period.

Integrated Capacity Solutions (ICS)

ICS revenue increased 49% during the current quarter compared to the second quarter of 2025. Overall segment volume increased 19% versus the prior-year period with growth in both published and spot volume. Revenue per load increased 26% due to higher rates across both contractual and transactional volume. Contractual volume represented approximately 65% of the total load volume and 63% of the total revenue in the current quarter compared to 62% and 63%, respectively, in the second quarter 2025.

Operating income was $1.7 million compared to an operating loss of $3.6 million for the second quarter of 2025. The operating environment remained volatile during the current quarter as market capacity dynamics continue to evolve rapidly. Operating results improved from the prior-year quarter primarily due to an increase in gross profit driven by the increases in both revenue per load and volume which more than offset a 54% increase in purchased transportation expense. Gross profit margins decreased to 12.5% compared to 15.5% in the prior year period but improved from 12.0% in the first quarter of 2026.

Final Mile Services (FMS)

FMS revenue decreased 6% compared to the same period 2025. The decrease was primarily driven by known business losses given our ongoing efforts to improve revenue quality and profitability across various accounts. The decrease in segment gross revenue was partially offset by stabilizing demand across many of the end markets served and the implementation of new business awarded over the past year.

Operating income decreased 30% to $5.6 million compared to the prior-year period. Operating income decreased primarily due to the impact of lower revenue and higher purchased transportation expense. The operating income decline was partially offset by lower claims and facility rental expenses and continued progress on the initiative to lower our cost to serve.

Truckload (JBT)

JBT revenue increased 35% compared to the same period in the prior year. Revenue excluding fuel surcharge revenue increased 28% driven by a 14% increase in load volume and a 13% improvement in revenue per load excluding fuel surcharge revenue. Total average effective trailer count increased by approximately 45 units, or less than 1% versus the prior-year period. Trailer turns in the quarter improved 13% from the prior period primarily due to improved network balance and velocity to improve equipment utilization.

Operating loss was $1.3 million compared to operating income of $3.4 million for the second quarter 2025. Operating performance declined from the prior year period primarily due to higher purchased transportation expense, which resulted in a 12% decline in gross profit. This was partially offset by continued cost management and productivity and a more balanced network. JBT segment operating income as a percentage of segment gross revenue decreased year-over-year as a result of higher third-party capacity costs as a percentage of gross revenue.

At June 30, 2026, we had approximately $1.15 billion outstanding on various debt instruments compared to $1.72 billion at June 30, 2025 and $1.47 billion at December 31, 2025.
