AVOCENT ADDS TWO MILLION SHARES
TO SHARE REPURCHASE PROGRAM

HUNTSVILLE, Ala. (February 5, 2007) — Avocent Corporation (NASDAQ: AVCT) announced today that its Board of Directors approved the addition of two million additional shares to the Company’s stock repurchase program. Ten million shares were previously approved for repurchase under this program. Avocent has returned $270 million to shareholders through the 9.8 million shares repurchased to date under the program. The stock purchases may be made from time to time in the open market or in privately negotiated transactions at prices that the Company deems appropriate.

“The stock repurchase authorization highlights our optimism about Avocent’s continued growth,” stated John R.
