On Thursday, November 8, 2007, Knight Transportation, Inc., an Arizona corporation (the "Company"), announced that Mark Scudder will step down as a member of the Board of Directors effective November 9, 2007.   Mr. Scudder will remain securities and merger and acquisition counsel to the Company and will serve as a strategic legal advisor to the Board.  In announcing the move, Chairman and CEO Kevin Knight stated: "Mark has been a close and important advisor to Knight Transportation for nearly a decade, during which our annual revenue base grew from approximately $150 million in 1999 to approximately $700 million while expanding our geographic footprint and portfolio of service offerings. As our activities and Mark's role have expanded and evolved, we jointly decided that his stepping down from his director role would be appropriate and would increase flexibility in the future.  The Board appreciates Mark's service and looks forward to the continuing relationship."
Mr. Scudder added: "Knight has an outstanding Board of Directors and management team that have delivered industry-leading performance and shareholder returns with great integrity.  It has been an honor to serve on the Board, and I look forward to continuing to serve the Company for many years to come."
After giving effect to Mr. Scudder's resignation, the majority of the members of the Company's Board of Directors will continue to be independent.
Item 7.01
Regulation FD Disclosure.
The Company also announced today that the Board of Directors of the Company voted unanimously to authorize the repurchase of up to 3.0 million shares of the Company's Common Stock.  The repurchase authorization will continue in effect until the share limit is reached or the program is terminated by the Company.  The repurchase authorization is intended to afford the Company the flexibility to acquire shares opportunistically in future periods and does not indicate an intention to repurchase any particular number of shares within a definite timeframe.  Any repurchases would be effected based upon share price and market conditions. The authorization extends to purchases of shares to prevent dilution from equity compensation awards as well as open market and negotiated transactions.
