EXTREME NETWORKS REPORTS INCREASED REVENUE AND PROFITABILITY

SANTA CLARA, Calif., Oct. 20, 2004 – Extreme Networks, Inc. (Nasdaq: EXTR), a leader in open converged networks, today announced financial results for its fiscal first quarter ended Sept. 26, 2004.

Net revenue for the first quarter of fiscal 2005 was $95.1 million, up three percent from $92.2 million in the fourth fiscal quarter of 2004, and up nine percent from $87.4 million in the year-ago first quarter. On a GAAP basis, the Company recorded net income of $4.1 million or $0.03 per diluted share in the first fiscal quarter of 2005, up from the net income of $2.6 million or $0.02 per diluted share in the first fiscal quarter of 2004.

“Our positive financial results represent another quarter of market adoption for our innovative switching solutions that Enterprises and Metro Service providers are using to build open converged networks,” said Gordon Stitt, president and CEO of Extreme Networks. “We are very pleased to have increased revenue, profitability, gross margins and cash flow, while controlling our expenses.”

Operating income for the first quarter of fiscal 2005 totaled $4.7 million, an operating margin of 5.0 percent of net revenues, up from $1.2 million or 1.4 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 53.2 percent of revenues during the fiscal first quarter of 2005, compared to 52.5 percent in the fiscal fourth quarter of 2004, and 51.4 percent in the year-ago first quarter. Operating expenses declined to 48.2 percent of revenues, from 56.4 percent in the fiscal fourth quarter of 2004, and from 50.0 percent in the year-ago first quarter.

Cash and cash equivalents, short-term investments, and marketable securities increased to $439.9 million during the quarter, up from $425.7 million at the end of the fiscal fourth quarter 2004, and up from $403.3 million at the end of the fiscal first quarter of 2004.

Revenues in the U.S. were $40.4 million in the first quarter of fiscal 2005, or 42 percent of total consolidated revenue; international revenues were $54.7 million or 58 percent of total consolidated revenue. In the first quarter of fiscal 2004, revenues in the U.S. were $36.4 million, or 42 percent of total consolidated revenue; international revenues were $51.0 million, or 58 percent.

Management Expectations

For the quarter ending Dec. 26, 2004, the Company currently anticipates that its revenues will be up one to five percent relative to the Sept. quarter just completed. The Company anticipates that gross margin as a percentage of net revenue will be similar to the 53.2 percent reported in Sept. The Company anticipates total operating expenses will be in a range of $46 to $47 million.
