ArcBest Raises Q2 Outlook as LTL Market Strengthens

ArcBest announced a significant upward revision to its second-quarter guidance for both asset-based and asset-light business segments, reflecting stronger-than-expected market conditions in the less-than-truckload (LTL) and brokerage sectors. 8% adjusted OR—a 200 bps improvement year-over-year. This improvement outpaces the unit's typical 350 bps sequential gain from Q1 to Q2, signaling an acceleration driven by disciplined pricing execution, favorable fuel cost dynamics, and operational efficiency gains. The positive revision is underpinned by strengthening demand signals visible in April and May month-to-date metrics.

9% year-over-year in April (vs. 3% in May on a two-year stacked basis. Notably, the tonnage gains reflect heavier shipments as more full truckload volumes flow through the LTL network, suggesting robust industrial activity and customer freight consolidation patterns. ArcBest's asset-light segment (truck brokerage and managed transportation) also outperformed, with guidance raised by $2 million at each end of the operating income range to $3M–$5M, driven by 15% growth in daily shipments and 11% higher revenue per shipment.

These improvements align with improving macroeconomic conditions, particularly the Institute for Supply Management's Manufacturing PMI, which reached 54 in May—the highest reading in four years—signaling an inflection in industrial activity that typically precedes LTL volume growth by several months. For supply chain professionals, this represents a shift from the softer freight environment of late 2024 and early 2025, with implications for capacity planning, rate negotiations, and provider relationships across the trucking ecosystem.
