Thomasville, N.C.-based national less-than-truckload (LTL) carrier Old Dominion Freight Line (ODFL) provided guidance for key May operating metrics this week.

ODFL reported that revenue per day was down 5.8% annually in May, driven by an 8.4% decline in revenue tons per day which was partially offset by an increase in LTL revenue per hundredweight.

And the company added that the decrease in LTL tons per day was attributable to a 6.8% decrease in LTL shipments per day and also a 1.9% decrease in LTL weight per shipment. For the quarter-to-date period, ODFL said LTL revenue per hundredweight and LTL revenue per hundredweight, excluding fuel surcharges, increased 3.2% and 5.6%, respectively, on an annual basis.

“Our revenue results for May reflect continued softness in the domestic economy as well as the impact of lower fuel prices on our yields,” said Marty Freeman, President and Chief Executive Officer of Old Dominion. “We believe that our market share has remained relatively consistent throughout this extended period of economic softness, despite the year-over-year decrease in our LTL volumes. Customers have continued to value our industry-leading service, which supports our ongoing yield management initiatives. While the macroeconomic environment remains uncertain, we will continue to focus on executing on our long-term strategic plan. Our service metrics and value proposition remain best in class, which we believe puts us in a unique position to win profitable market share and increase shareholder value over the long term.”

In its first quarter earnings statement released in April, ODFL reported net revenue came in at $1.37 billion, which fell 5.8% annually, with net income, at $254.7 million, falling 13% annually.

Freeman said that ODFL’s financial results for the first quarter reflect the ongoing softness in the domestic economy, adding that while the company was encouraged to see signs of improving demand during the first quarter, there continues to be uncertainty with the economy.
