Net income computed in accordance with U.S. generally accepted accounting principles (GAAP) for the third quarter of 2010 was $327 million, or $.60 per share (diluted), compared with GAAP net income of $278 million, or $.52 per share (diluted), for the second quarter of 2010, and GAAP net income of $85 million, or $.16 per share (diluted), for the third quarter of 2009.

Net revenue for the nine months ended September 30, 2010 was $4.873 billion.

For a discussion of certain selected transactions and their related accounting impact for all periods presented, see the “Unaudited Supplementary Financial Data” schedule below.

“Broadcom continues to execute exceptionally well with record revenue and earnings in the third quarter of 2010. I am particularly pleased that we had record sales in each of our segments and reached our GAAP product operating margin model of 15% — 17%. These achievements are due to solid growth in our wired and wireless communication businesses, powerfully engineered products and Broadcom’s continued commitment to financial discipline,” said Scott A. McGregor, Broadcom’s President and Chief Executive Officer.

“Looking ahead, we believe that consumer demand for connectivity will continue to drive demand for our communication semiconductors, which should enable Broadcom to deliver solid revenue growth and sustained profitability in the fourth quarter.”
