AVOCENT ANNOUNCES EXPANDED STOCK BUYBACK PROGRAM

———————————

Signs $250 Million Revolving Line of Credit

HUNTSVILLE, Ala. — June 19, 2006 — Avocent Corporation (NASDAQ:AVCT) announced today that its Board of Directors approved an expanded stock repurchase program for up to three million additional shares of the Company’s common stock. The Company also announced that it has closed on a $250 million unsecured five year revolving bank line of credit.

“We plan to use the repurchased shares to fund a portion of the stock component in our recently announced acquisition of LANDesk,” stated John R. Cooper, chairman and chief executive officer of Avocent Corporation. “We believe our Board’s authorization to double the size of this stock buyback program underscores their confidence in the future of Avocent.”

Avocent expects to close the LANDesk acquisition in the third quarter of 2006. The $400 million acquisition will be funded with $200 million in cash and $200 million in Avocent common stock. To date, Avocent has purchased seven million shares under its previous share repurchase programs.

“We used our strong cash position and cash flow to fund the stock repurchases to date,” continued Mr. Cooper. “We recently purchased all the shares authorized under existing repurchase programs, including the three-million-share repurchase program announced last month. We expect the buyback program to reduce the impact from new shares to be issued as part of the acquisition of LANDesk.

“The signing of the $250 million unsecured five year revolving bank line of credit provides Avocent with increased financial flexibility. The line of credit bears an initial interest rate of LIBOR plus 112.5 basis points. We anticipate that the revolving credit line will be used to fund a portion of our future stock repurchases,” concluded Mr. Cooper.
