                Avocent Revises Fourth Quarter Results

      Does Not Expect to Pay Contingent Consideration on LANdesk
                              Acquisition


    HUNTSVILLE, Ala.--(BUSINESS WIRE)--March 1, 2007--Avocent
Corporation (NASDAQ: AVCT) announced today that it was revising
previously reported fourth quarter revenue for its LANDesk Division to
reduce revenue by $2.8 million and consolidated operational income by
$1.9 million. Together with a reduction in tax expense discussed
below, consolidated GAAP net income was reduced by $0.7 million.
Avocent also announced that it now does not expect to pay the
previously accrued contingent consideration of $27 million relating to
the LANDesk acquisition.

    "We became aware that several previously recorded transactions did
not meet the stringent revenue recognition criteria for sales of
software and that certain royalties earned by LANDesk should have been
recorded prior to the closing date of the acquisition," stated Edward
H. Blankenship, Avocent's chief financial officer. "These revenue
adjustments were partially offset by lower management bonus accruals,
and we will continue to evaluate certain other costs, primarily
commissions, related to these transactions. We also determined that
certain tax benefits relating to Avocent stock options exercised in
2006, which were assumed in prior acquisitions, should be included in
the determination of net income instead of equity for GAAP purposes."

    As revised, Avocent's fourth quarter consolidated revenue
increased 55% to $166.1 million in 2006 from $106.8 million in 2005
and fourth quarter operational income per diluted share increased to
$0.59 in 2006 from $0.49 in 2005. Revised consolidated revenue for the
year ended December 31, 2006 increased 41% to $520.9 million from
$369.9 million in 2005. Revised operational income per diluted share
increased to $1.96 in 2006 from $1.31 in 2005.

    "We remain very excited and optimistic about the many
opportunities we have with LANDesk and the joint product development
activities we have underway," added John Cooper, Avocent's chairman
and chief executive officer. "Over the past few weeks I have talked
with several key channel partners and LANDesk sales force members, and
I am quite encouraged by the strength and depth of our relationships
with these key contributors and the pipeline of potential deals we
have to pursue."

    A summary of the revised results for the fourth quarter of 2006
follows at the end of this release. More information on the 2006
results can be found in Avocent's Annual Report on Form 10-K filed
with the Securities and Exchange Commission today.

    Use of Non-GAAP Financial Measures

    Income prior to intangible amortization, stock compensation and
in-process research and development expenses, or operational income as
used in the attached financial statement schedules, is not a measure
of financial performance under generally accepted accounting
principles (GAAP) and should not be considered a substitute for or
superior to GAAP. Avocent's management uses operational income as a
financial measure to evaluate performance and allocate resources
within the Company. Management believes this measure presents the
Company's results on a more comparable operational basis by excluding
non-cash amortization expenses, non-operational expenses associated
with acquisitions, and non-cash stock-based compensation expense.
Avocent believes that operational income is a measure of performance
used by many investment banks, analysts, investors and others to make
informed investment decisions. Other companies may calculate
operational income in a different manner so this measure may not be
comparable to similar measures presented by other companies. A
reconciliation of Avocent's results using operational measures and
GAAP is set forth in the condensed consolidated statements of
operations included in this press release.
