YRC Worldwide shares were lower after the trucking company reported a bigger-than-expected quarterly loss, citing a shortage of drivers.

The company said that its cost-cutting had led to a shortage of drivers at some terminals, forcing it to pay overtime and hire third-party carriers.

The situation was exacerbated by summer holidays, YRC said.

“Simply put, we were operating an inefficient network,” Chief Executive James Welch said on a conference call, after the company reported a net loss of $44.4 million, or $4.45 per share, for the third quarter ended Sept. 30.

Analysts on average had expected a loss of 46 cents per share, according to Thomson Reuters I/B/E/S.

YRC said in August that it was considering refinancing its debt as the trucking industry faced challenges ranging from a shortage of experienced drivers to new regulations that required truckers to work shorter hours.

The company’s revenue rose 1 percent to $1.25 billion, slightly below the average analyst estimate of $1.26 billion. (Reuters)
