Extreme Networks Reports Preliminary Revenue

Schedules First Quarter Conference Call for October 26

SANTA CLARA, Calif., Oct. 5 /PRNewswire-FirstCall/ -- Extreme Networks, Inc.
(Nasdaq: EXTR) today released preliminary revenue for its 2010 fiscal first
quarter ended September 27, 2009. For the quarter, net revenue is expected to
be approximately $66 million.

"Our supply chain was constrained during the quarter, impacting our ability to
deliver product, close transactions and recognize revenue. Our North America
business was particularly soft, as some deals were lost and others were
delayed beyond the end of the quarter," said Mark Canepa, president and CEO of
Extreme Networks. "I am disappointed that we did not execute to our advantage.
However, on a positive note, we expect to report that backlog and deferred
revenue increased by approximately $6 million and total cash increased
approximately $3 million for the quarter. We and our Board of Directors are
committed to addressing the issues that produced these results. I look
forward to giving a complete update on our earning release conference call.
Further, we are anticipating giving guidance for our second quarter on the
call."
