Old Dominion Freight Line Inc. stock rose more than 5 percent after it reported earnings and revenue that beat analyst estimates as a result of increased shipping volumes and increased prices, according to a filing made Thursday with the Securities and Exchange Commission.

The Thomasville-based trucking company reported third quarter revenue of $873 million, a 11.5 percent increase from the same time last year. This beat analyst estimates of $855.5 million.

Earnings per share of $1.24 also surpassed analyst estimates of $1.16.

David Congdon, the company’s chief executive officer, attributes the growth in revenue to an 8.6 percent increase in less-than-load tons per day and a 3.6 percent increase in LTL revenue per hundred pounds, despite a 0.6 percent decrease in length of haul.

“The strengthening economy supported our third quarter revenue growth, but we also believe that tightening industry capacity and pricing increases accelerated the pace of our revenue growth for September,” Congdon said regarding strengths for the quarter.

The filing also revealed that Old Dominion’s operating ratio improved 120 points to a company record of 81.2 percent. This was attributed to the improvement in freight density and yield, which created operating leverage.

Old Dominion’s stock price has risen 5.24 percent, or $5.84, since the market opened on Thursday and is trading at $117.25.

The company operates 227 service centers with coverage across the continental United States, as well as access to services in some areas of Canada, Europe, Mexico, and China.
