Knight Transportation, Inc. (NYSE:KNX)("Knight"), one of North America's largest and most diversified truckload transportation companies, today issued the following statement regarding USA Truck, Inc.'s (NASDAQ:USAK) rejection of Knight's $9.00 per share, all-cash, premium proposal:

We are disappointed that USA Truck has once again rejected Knight's all-cash, premium proposal. Since making our proposal public, we have had discussions with several of USA Truck's largest shareholders that have indicated their support for our proposal and have encouraged us to continue to take the necessary steps to acquire USA Truck. We continue to believe that a combination of Knight and USA Truck is better positioned to deliver value for and is in the best interest of all of Knight and USA Truck's stakeholders, and we are prepared to take the necessary steps to make this combination a reality.

Knight also announced today that it has filed with the U.S. Securities and Exchange Commission an amendment to its Schedule 13D, originally filed on September 26, 2013, disclosing an increased ownership position of 1,192,364 shares of USA Truck common stock, representing approximately 11.3% of USA Truck's shares outstanding.

As previously announced on September 26, 2013, Knight proposed to acquire all of the outstanding shares of USA Truck for $9.00 per share in cash, valuing the equity of USA Truck at approximately $95 million. The total value of the proposed transaction is approximately $242 million, including USA Truck's approximately $147 million of outstanding net indebtedness. The proposal represents a significant premium of approximately 39% to USA Truck's closing price on September 25, 2013, the last trading day prior to public announcement of Knight's proposal; a premium of approximately 50% to USA Truck's average closing price for the ten trading day period prior to Knight's announcement; and a premium of approximately 58% to USA Truck's closing price on August 27, 2013, the last trading day prior to Knight's August 28, 2013, proposal letter to USA Truck's Board of Directors.

Evercore is acting as financial advisor to Knight and Fried, Frank, Harris, Shriver & Jacobson LLP is acting as Knight's legal advisor.
