Marten Transport's Q2 revenue from its non-dedicated truckload (TL) reefer fleet increased 9% year-over-year to $116 million.

This revenue growth occurred despite an 8% reduction in average tractors in service, driven by a 9% increase in revenue per tractor and a 6% rise in revenue per loaded mile to $2.81. The company attributes this to a tightening reefer market, which is allowing Marten to optimize freight selection and push rate increases. Regulatory actions removing non-compliant drivers have contributed to reduced capacity, benefiting established carriers like Marten Transport.
