EXTREME NETWORKS REPORTS FOURTH QUARTER RESULTS

SANTA CLARA, Calif., July 18, 2003 – Extreme Networks, Inc. (Nasdaq: EXTR), a leader in Ethernet broadband networking solutions, today announced financial results for the fiscal fourth quarter ended June 29, 2003. Net revenue for the fourth quarter was $87.3 million, an increase from the third quarter revenue of $85.2 million.

“We are pleased to show sequential sales growth, particularly in the U.S. market, during this challenging economy,” said Gordon Stitt, president and CEO of Extreme Networks. “Initial customer response to our newly introduced Unified Access Architecture, which includes our Summit 300 and Altitude 300 WLAN switches, our new Triumph-based products, and our Fourth Generation Network Silicon System, has been very positive. Our ongoing commitment to R&D during this economic downturn continues to generate results.”

In accordance with the Statement of Financial Accounting Standards No. 109 (“Accounting for Income Taxes”), the Company recorded a non-cash charge of $154 million for the fourth quarter of fiscal 2003 to establish a valuation allowance against its deferred tax assets. The net loss for the quarter, including this non-cash charge, was $170.4 million or ($1.47) per share, which includes a loss of $1.33 per share for the tax charge. Pro-forma* results, net of the tax valuation allowance and one-time charges resulted in revenues of $87.3 million, up from $85.2 million in the third quarter, and a loss of $0.06 per share, compared to the previous quarter loss of $0.06 per share.

“The SFAS No. 109 places greater weight on previous cumulative losses than the outlook for future profitability when determining whether deferred tax assets can be used,” added Stitt. “We will periodically review this valuation allowance, and it can be reversed, partially or totally in the future.”

Conference Call

Extreme Networks will host a conference call to discuss these results at 8:30 a.m. EDT (5:30 a.m. PDT), for more information visit http://www.extremenetworks.com/aboutus/investor/ Financial and statistical information to be discussed during the conference call are posted on the Investor Relations section of the Company’s web-site (www.extremenetworks.com).
