Material Changes Versus Prior Period
The Asset-Based segment saw a shift in freight profile, with significantly heavier shipments offsetting a decline in shipment volume. While billed revenue per shipment rose 13%, revenue per hundredweight remained flat, indicating that price increases were primarily volume-weight driven rather than pure rate hikes. In the Asset-Light segment, strong pricing power and a tightening truckload market drove a 27% revenue increase, with revenue per shipment up 22%.
Guidance, Outlook, and Risks
Management expects the Asset-Based non-GAAP operating ratio to remain stable in Q3 2026 compared to Q2 2026. The Asset-Light segment outlook reflects continued yield discipline and productivity improvements. The filing includes a comprehensive "safe harbor" statement identifying risks such as cybersecurity incidents, supply chain disruptions, fuel price volatility, labor relations (including union negotiations), and potential impairment of long-lived assets.
Investor Verification Checklist
