Knight Transportation, Inc. (NYSE: KNX)(''Knight''), one of North America's largest and most diversified truckload transportation companies, today provided an update on its guidance for the third and fourth quarters of 2013.

Based on preliminary results, Knight now expects earnings per diluted share will range from:

  • $0.18 to $0.20 for its third quarter ended September 30, 2013, compared with its prior estimates of $0.22 to $0.24; and
  • $0.20 to $0.23 for its fourth quarter ending December 31, 2013, compared with its prior estimates of $0.22 to $0.25.

A number of factors negatively impacted the third quarter of 2013, which has resulted in expected earnings below original estimates. We experienced lower miles per tractor year over year, despite having 3.6% less trucks in the third quarter of 2013 than in the third quarter of 2012, revenue per mile improvement fell short of our targeted level, and increased driver recruiting, training, and payroll costs.

Soft freight demand, particularly in the first half of the quarter, challenges related to recruiting qualified driving associates, and the new industry-wide regulations governing hours of service that went into effect in July 2013 were among the factors affecting the quarter.

Kevin Knight, Chairman and Chief Executive Officer of Knight stated, ''In recent weeks, we have seen improvement in driver recruiting, which reduced the number of unseated tractors, and have begun to see pickup in some previously soft freight markets. We believe that our industry-leading operating efficiency positions Knight for continued success, and enables us to capitalize on growth opportunities during these challenging times in our industry.''
