Con-way Inc. reported higher earnings that were slightly below Wall Street forecasts and revenue that was in line with estimates.

Tonnage at Con-way Freight, the company's less-than-truckload unit, which accounts for 60 percent of overall revenue, is running relatively flat year over year, executives told analysts on a conference call.

"The real ability to really expand margins and get back to historic levels depends on the growth environment, and we haven't been seeing much of a growing environment this year," Chief Executive Officer Doug Stotlar said.

The company cited price increases to shippers and cost controls for its earnings increase. (Reuters)
