(11) Revenue and Business Segments

We account for our revenue in accordance with FASB ASC 606, Revenue from Contracts with Customers. We combine our five current operating segments (Temperature-Sensitive and Dry Truckload, Dedicated, Brokerage and MRTN de Mexico), along with our Intermodal operating segment which was sold effective September 30, 2025, into four reporting segments (Truckload, Dedicated, Brokerage and Intermodal) for financial reporting purposes. These four reporting segments are also the appropriate categories for the disaggregation of our revenue under FASB ASC 606.

Our Truckload segment provides a combination of regional short-haul and medium-to-long-haul full-load transportation services. We transport food and other consumer packaged goods that require a temperature-controlled or insulated environment, along with dry freight, across the United States and into and out of Mexico and Canada. Our agreements with customers are typically for one year.

Our Dedicated segment provides customized transportation solutions tailored to meet each individual customer’s requirements, utilizing temperature-controlled trailers, dry vans and other specialized equipment within the United States. Our agreements with customers range from three to five years and are subject to annual rate reviews.

Generally, we are paid by the mile for our Truckload and Dedicated services. We also derive Truckload and Dedicated revenue from fuel surcharges, loading and unloading activities, equipment detention and other accessorial services. The main factors that affect our Truckload and Dedicated revenue are the rate per mile we receive from our customers, the percentage of miles for which we are compensated, the number of miles we generate with our equipment and changes in fuel prices. We monitor our revenue production primarily through average Truckload and Dedicated revenue, net of fuel surcharges, per tractor per week. We also analyze our average Truckload and Dedicated revenue, net of fuel surcharges, per total mile, non-revenue miles percentage, the miles per tractor we generate, our fuel surcharge revenue, our accessorial revenue and our other sources of operating revenue.

Our Brokerage segment develops contractual relationships with and arranges for third-party carriers to transport freight for our customers in temperature-controlled trailers and dry vans within the United States and into and out of Mexico through Marten Transport Logistics, LLC, which was established in 2007 and operates pursuant to brokerage authority granted by the United States Department of Transportation, or DOT. We retain the billing, collection and customer management responsibilities. The main factors that affect our Brokerage revenue are the rate per mile and other charges that we receive from our customers.

Operating results of our MRTN de Mexico business, which offers our customers door-to-door service between the United States and Mexico with our Mexican partner carriers, is reported within our Truckload and Brokerage segments.

Our Intermodal segment transported our customers’ freight within the United States utilizing our refrigerated containers on railroad flatcars for portions of trips, with the balance of the trips using our tractors or, to a lesser extent, contracted carriers. The main factors that affected our Intermodal revenue were the rate per mile and other charges we received from our customers. As discussed in Note 10, our Intermodal operations were sold effective September 30, 2025.

Our customer agreements are typically for one-year terms except for our Dedicated agreements which range from three to five years with annual rate reviews. Under FASB ASC 606, the contract date for each individual load within each of our four reporting segments is generally the date that each load is tendered to and accepted by us. For each load transported within each of our four reporting segments, the entire amount of revenue to be recognized is a single performance obligation and our agreements with our customers detail the per-mile charges for line haul and fuel surcharges, along with the rates for loading and unloading, stop offs and drops, equipment detention and other accessorial services, which is the transaction price. There are no discounts that would be a material right or consideration payable to a customer. We are required to recognize revenue and related expenses over time, from load pickup to delivery, for each load within each of our four reporting segments. We base our calculation of the amount of revenue to record in each period for individual loads picking up in one period and delivering in the following period using the number of hours estimated to be incurred within each period applied to each estimated transaction price. Contract assets for this estimated revenue which are classified within prepaid expenses and other within our consolidated condensed balance sheets were $1.8 million and $1.4 million as of June 30, 2026 and December 31, 2025, respectively. We had no impairment losses on contract assets in the first six months of 2026 or in 2025. As a practical expedient as permitted under FASB ASC 606-10-50-14, we do not disclose the value of unsatisfied performance obligations for contracts with an original expected duration of one year or less. We bill our customers for loads after delivery is complete with standard payment terms of 30 days.

We account for revenue of our Brokerage segment and formerly of our Intermodal segment, along with revenue on freight transported by independent contractors within our Truckload and Dedicated segments, on a gross basis because we are the principal service provider controlling the promised service before it is transferred to each customer. We are primarily responsible for fulfilling the promise to provide each specified service to each customer. We bear the primary risk of loss in the event of cargo claims by our customers. We also have complete control and discretion in establishing the price for each specified service. Accordingly, all such revenue billed to customers is classified as operating revenue and all corresponding payments to carriers for transportation services we arrange in connection with brokerage and formerly intermodal activities and to independent contractor providers of revenue equipment are classified as purchased transportation expense within our consolidated condensed statements of operations.

The following table sets forth for the periods indicated our operating revenue and operating income by segment.

The following segment operating results for the periods indicated are provided monthly to our chief operating decision maker, our Chairman of the Board and Chief Executive Officer, and used in assessing segment performance and allocating resources, primarily based upon each segment’s variances in operating revenue, operating income and operating ratio. We do not prepare separate balance sheets by segment and, as a result, assets are not separately identifiable by segment.
