EXTREME NETWORKS REPORTS 20 PERCENT REVENUE GROWTH AND

IMPROVED PROFITABILITY

SANTA CLARA, Calif., Jan. 19, 2005 – Extreme Networks, Inc. (Nasdaq: EXTR), a leader in open converged networks, today announced financial results for its fiscal second quarter ended Dec. 26, 2004.

Net revenue for the second quarter of fiscal 2005 was $100.3 million, up 20 percent from $83.4 million in the year-ago second quarter, and up 5 percent from $95.1 million in the first fiscal quarter of 2005. The Company recorded net income of $9.95 million or $0.08 per diluted share in the second fiscal quarter of 2005, up from the net loss of ($5.6) million or ($0.05) per diluted share in the second fiscal quarter of 2004.

“We are very pleased with our continued growth in sales, gross margin and profitability,” said Gordon Stitt, president and CEO of Extreme Networks. “Our performance reflects the positive response from customers for our innovative networking solutions that allow customers to build converged networks that easily embrace emerging applications, such as voice. Our two-tier network architecture, that includes our new, voice-class Aspen switch for the edge, is being adopted by enterprises and metro Ethernet service providers.”

Revenues in the U.S. were $43.4 million in the second quarter of fiscal 2005, or 43.3 percent of total consolidated revenue. U.S. revenues were up 54 percent from the $28.2 million in the year-ago quarter. International revenues were $56.9 million or 56.7 percent of total consolidated revenue, up from the $55.2 million in the year-ago quarter. Revenues in the Company’s European region, including the Middle East and Africa, were up 21 percent in the second quarter of 2005 compared with the second quarter of fiscal 2004.

Operating income, for the second quarter of fiscal 2005 totaled $7.8 million, an operating margin of 7.8 percent of net revenues, up from an operating loss of ($5.8) million or (6.9) percent of net revenues in the year-ago period. The Company’s improved operating margin was the result of higher revenues, expanded gross margins, and decreased operating expenses as a percentage of sales. Total gross margin was 53.8 percent of revenues during the fiscal second quarter of 2005, compared to 53.2 percent in the fiscal first quarter of 2005, and 48.5 percent in the year-ago second quarter. Operating expenses declined to 46 percent of revenues, from 48.2 percent in the fiscal first quarter of 2005, and from 55.4 percent in the year-ago second quarter.

Other income and expenses for the quarter included $3.9 million for a foreign consumption tax refund, which increased earnings per share by $0.03 per share.

Cash and cash equivalents, short-term investments, and marketable securities increased to $446.8 million during the quarter, up from $439.9 million at the end of the fiscal first quarter 2005, and up from $412.6 million at the end of the fiscal second quarter of 2004.

Management Expectations
