Knight to be listed on NYSE

| 12/20/2004

The common stock of Knight Transportation Inc. has been accepted for listing on the New York Stock Exchange. The company anticipates that its shares will begin trading on the NYSE on Dec. 30 under the symbol “KNX.” Until then, the company's shares will continue trading on the Nasdaq National Market under the symbol “KNGT.”

Knight Transportation has grown from one operation center in Phoenix, AZ, to 17 operation centers throughout the country. In the 10 years from 1994 – the year of its initial public offering – through 2003, the company’s revenue before fuel surcharges grew from $37.5 million to $326.9 million, according to Kevin Knight, president of Knight Transportation. He also said the company’s earnings grew from $4.1 million to $35.5 million.

“This moves makes Knight the only major truckload carrier listed on the New York Stock Exchange, which is a positive reflection on what Kevin Knight has created there in the last 15 years,” Donald Broughton, transportation analyst with A.G. Edwards, said.

Knight Transportation joins only two other trucking companies to be traded on the New York Stock Exchange – CNF Inc., the parent company of companies such as Con-Way Transportation, and SIRVA Inc., the parent company of relocation companies such as Allied and North American.
