FOR IMMEDIATE RELEASE

J.B. HUNT TRANSPORT SERVICES, INC. REPORTS REVENUES AND EARNINGS

FOR THE FIRST QUARTER 2018

LOWELL, ARKANSAS, April 16, 2018 - J.B. Hunt Transport Services, Inc., (NASDAQ:JBHT) announced first quarter 2018 net earnings of $118.1 million, or diluted earnings per share of $1.07 vs. first quarter 2017 net earnings of $102.7 million, or 92 cents per diluted share.

Total operating revenue for the current quarter was $1.95 billion, compared with $1.63 billion for the first quarter 2017. Current quarter total operating revenue, excluding fuel surcharges, increased 17% vs. first quarter 2017. Intermodal (JBI) load growth was 6% and revenue per load excluding fuel surcharges increased approximately 4% over first quarter 2017 levels. Dedicated Contract Services (DCS) segment revenue increased by 26% over prior year primarily from additional customer contracts from a year ago and customer rate increases. Integrated Capacity Solutions (ICS) load growth was 6% and revenue per load increased approximately 34% over the same period in 2017. Truck (JBT) segment revenue decreased 1% primarily from fewer seated trucks compared to a year ago.

Operating income for the current quarter totaled $169 million vs. $149 million for the first quarter 2017. Benefits from volume growth, higher customer rates, new customer contracts and a continuing vibrant spot pricing market were partially offset by increased purchased transportation costs; lower intermodal network utilization; lower productivity in winter weather affected regions; higher driver and non-driver salaries, wages and benefits; higher Final Mile Services (FMS) network facilities costs; higher maintenance costs on equipment scheduled to be traded in 2018; increased technology spend on legacy system upgrades; continuing branch network expansion; increased equipment ownership costs and increased insurance and claims costs.

Net interest expense for the current quarter increased 34% from the same period in 2017 due to higher effective interest rates on our debt.

The effective income tax rate decreased to 26.0% in the current quarter compared to 28.0% in the first quarter 2017 due to the estimated impact of the Tax Cuts and Jobs Act of 2017. First quarter 2017 recorded a one-time tax benefit of $13.6 million or 12 cents per diluted share from the claiming of research and development tax credits and domestic production tax deductions incurred during the 2012 through 2016 tax years. The annual tax rate for 2018 is estimated to be 26.0%.

Segment Information:

Intermodal (JBI)

JBI load volumes grew 6% over the same period 2017. Transcontinental loads grew 2%, and the Eastern network load volume grew 12% compared to prior year. Revenue grew approximately 14% reflecting the 6% volume growth and an 8% increase in revenue per load, which is determined by the combination of customer rates, fuel surcharges and freight mix. Revenue per load excluding fuel surcharge revenue increased approximately 4% year over year.

Operating income increased 20% from prior year. Benefits from volume growth, customer rate increases and freight mix were partially offset by an increase in rail purchased transportation costs; reduced network utilization and lower dray efficiency created from rail congestion, customer equipment pool utilization and a tight third party dray market; higher equipment ownership costs; increased driver wages and recruiting costs; increased costs for onboarding and integration of container tracking technologies and insurance and claims costs compared to the same period in 2017. The current period ended with approximately 89,500 units of trailing capacity and 5,450 power units assigned to the dray fleet.

Dedicated Contract Services (DCS)

DCS revenue increased 26% during the current quarter over the same period 2017. Productivity (revenue per truck per week) increased approximately 5% vs. 2017. Productivity excluding fuel surcharges increased approximately 2% primarily from customer rate increases partially offset by lower productivity and operating velocity (loads per week) at accounts in the winter weather affected areas of the Midwest and Northeast regions compared to 2017. Included in the DCS revenue growth, Final Mile Services (FMS) recorded an increase of $35 million (including approximately $25 million from the July 2017 acquisition), a 75% increase in FMS revenue, compared to first quarter 2017.

A net additional 1,329 revenue producing trucks, 184 net additions compared to fourth quarter 2017, were in the fleet by the end of the quarter compared to prior year. Approximately 55% of these additions represent private fleet conversions and 32% represent FMS vs. traditional dedicated capacity fleets. Customer retention rates remain above 98%.

Operating income decreased 9% from a year ago primarily from winter weather inefficiencies, higher insurance and claims costs, increased driver wages and recruiting costs, higher non-driver salaries wages and benefits, higher facilities rent and costs from the expanded FMS network, increased maintenance costs on equipment scheduled to be traded in 2018 and approximately $1.9 million in additional non-cash amortization expense compared to the same period a year ago.

Integrated Capacity Solutions (ICS)

ICS revenue increased 41% vs. first quarter 2017. Volumes increased 6% while revenue per load increased approximately 34% primarily due to a more vibrant spot pricing market compared to the same period a year ago. Spot volumes increased 43% and contractual volumes decreased approximately 7% from a year ago. Contractual business represents approximately 67% of total load volume and 44% of total revenue in the current period compared to 76% and 63%, respectively, in first quarter 2017. Of the total reported ICS revenue, approximately $96 million was executed through the marketplace for J.B. Hunt 360.

Operating income increased 99% over the same period in 2017 primarily from a higher revenue per load, a higher gross profit margin and a higher number of Mature branches (more than two years old) partially offset with continuing personnel growth costs and increased technology spending as marketplace for J.B. Hunt 360 continues its rollout. Gross profit margin increased to 14.4% in the current quarter vs. 14.3% last year primarily due to increased spot market activity. Total branch count grew to 44 locations compared to 42 at the end of the comparable period last year. ICS’s carrier base increased over 15% and employee count increased 14% compared to first quarter 2017.

Truck (JBT)

JBT revenue decreased 1% from the same quarter 2017. Revenue excluding fuel surcharge decreased approximately 3% primarily from a 15% decrease in load count partially offset by an increase in revenue per load. Revenue per load excluding fuel surcharge increased 14% primarily from a 10% increase in rates per loaded mile and a 3% increase in length of haul compared to the same period in 2017. At the end of the current quarter JBT operated 1,926 tractors compared to 2,144 in 2017.

Operating income for the current quarter increased by 4% compared to first quarter 2017. Benefits from the higher revenue per load were mostly offset by an approximate 10% decrease in tractor count, an average of 162 unseated trucks during the quarter, higher driver and independent contractor costs per mile and higher recruiting costs per driver and independent contractor compared to first quarter 2017.
