3COM REPORTS FIRST QUARTER RESULTS FOR FISCAL 2009

MARLBOROUGH, MASS. – September 22, 2008 – 3Com Corporation (NASDAQ: COMS) today reported financial results for its fiscal 2009 first quarter, which ended August 29, 2008. Revenue in the quarter was $342.7 million compared to revenue of $319.4 million in the corresponding period in fiscal 2008, a 7 percent increase.

     Net income in the quarter was $79.8 million, or $0.20 per diluted share, compared with a net loss of $18.7 million, or $0.05 per share, in the first quarter of fiscal year 2008. In the first quarter of fiscal 2009, 3Com recorded a $70.0 million, or $0.17 per diluted share, benefit from the previously disclosed resolution of a patent dispute between the company and Realtek. On a non-GAAP basis, net income was $43.4 million, or $0.11 per diluted share, compared with net income of $12.2 million, or $0.03 per diluted share, for the first quarter of fiscal year 2008.

     “Overall this was an excellent quarter for 3Com as we achieved GAAP profitability,” said Bob Mao, 3Com CEO. “In addition, we delivered our three key objectives in the quarter: solid year-over-year revenue growth, improved profit margins, including record gross margins again, and strong cash generation. These results exceeded our revised guidance for the quarter,

and showed several examples of improved execution of our strategy and the benefit of efficiencies gained from our integration activities. We believe that our strategy offers a compelling value proposition of price-performance leadership to value-conscious enterprise customers.”

     In the first quarter, 3Com generated $39.3 million in cash from operations. 3Com’s cash and cash equivalents balance at August 29, 2008, was $541.4 million.

     Management will host a conference call and Webcast at 5 p.m. EDT, Monday, September 22, 2008, to discuss the company’s financial results and business outlook.
