Silicon Image Revises Third Quarter 2009 Revenue Outlook

Silicon Image, Inc. (NASDAQ: SIMG), a leader in semiconductors and intellectual property for the secure distribution, presentation and storage of high-definition (HD) content, today announced that it expects revenue for fiscal third quarter 2009 to be below the financial guidance previously provided on July 23, 2009. The Company now expects its Q3 2009 revenue to be approximately $37 to $39 million, as compared to the previous guidance of $44 to $46 million.

“We are disappointed to report this revised revenue outlook,” said Hal Covert, the Company’s president and chief operating officer. “During the third quarter of 2009 we continued to experience the impact of the product transition the Company has been undergoing since 2008, in particular its effect on legacy products’ declining average selling prices. This factor, combined with our customers’ shift in production from high-end products to mid-range and low-end products, has put more pressure than anticipated on Silicon Image’s goal of improving revenue generation. We are looking forward to entering 2010 with our new product line-up that features HDMI® 1.4, Mobile High-Definition Link, and SteelVine™ Series 3 technologies,” continued Covert.

In other news, a separate press release was issued announcing the formation of the Mobile High-Definition Interface Working Group with Nokia Corporation, Samsung Electronics Co., Ltd, Silicon Image, Inc., Sony Corporation, and Toshiba Corporation. This is an important step in the process of Silicon Image moving forward with its strategy around Mobile High-Definition Link technology.
