AUSTIN, Texas – December 10, 2001– Cirrus Logic Inc. (Nasdaq: CRUS), the premier supplier of high-performance analog and DSP semiconductor solutions for consumer entertainment electronics, today completed its acquisition of Stream Machine Company, a leading supplier of MPEG-2 video recording technology. This acquisition strengthens Cirrus Logic’s ability to provide Total Entertainment (Total-E™) solutions for next generation, networked home entertainment applications. Stream Machine’s proprietary video compression technology provides high quality video for multiple home entertainment applications, such as DVD recorders, personal video recorders (PVRs), digital camcorders and PC video peripherals.

Cirrus Logic issued approximately 5.4 million shares of its common stock and options for privately held Stream Machine. As a result of this and two previously announced acquisitions that closed in October, Cirrus Logic anticipates that it will have approximately 83 million shares outstanding at the close of the December quarter. Tangible net assets of Stream Machine total approximately $2 million. In the September quarter, Stream Machine’s revenue was under $1 million and operating expenses were approximately $4 million. Cirrus estimates it will take a one-time non-cash charge in the December quarter for acquired in-process research and development in the range of $14 million to $20 million related to the acquisition. The remaining purchase price will be allocated primarily to amortizable intangibles and goodwill. Based on current Cirrus Logic forecasts, the acquisition is anticipated to be accretive to pro forma EPS within three quarters following the closing. As previously disclosed, it will have a dilutive effect of $0.00 to $0.02 per share in each of the next two quarters. Revenue from Stream Machine products is expected to grow from around $1 million in the December 2001 quarter to $30 million to $40 million in fiscal 2003, depending on a variety of factors, including continued strong growth in the DVD market and the rate at which consumers adopt digital video recording solutions for home use. Long-term gross margins are expected to be greater than 50 percent.

“Stream Machine’s superior digital video recording technologies will play a major role in Cirrus Logic’s leadership in the new era in entertainment electronics,” said David D. French, president and chief executive officer of Cirrus Logic. “Through this acquisition and those of LuxSonor and ShareWave in October, Cirrus Logic has become the pre-eminent provider of audio, video and networking technologies for digital entertainment devices.”

Market research firm Cahners In-Stat predicts that products that use MPEG encoding, such as Personal Video Recorders and DVD Recorders, will grow dramatically in the next few years. It estimates that PVRs will grow from approximately 520,000 units in 2001 to more than 11 million units in 2005, and DVD recorders will grow from 540,000 units this year to more than 17 million units in 2005.

Cahners In-Stat also predicts that the total MPEG-2 encoder chip market will grow 135 percent annually, from under two million units this year to more than 35 million units in 2005, representing a semiconductor market opportunity in excess of $370 million in 2005, up from $38 million this year.

“Stream Machine products are shipping in digital recording systems, which are manufactured by leading companies including Amoisonic, Datavideo and Malata. We are also seeing strong design win momentum throughout Japan, Korea and China,” said Michael L. Canning, formerly the CEO of Stream Machine and now general manager of the Video Recording Division of Cirrus Logic. “Cirrus Logic’s Whitecap™ wireless networking technology, developed by ShareWave, supports MPEG-2 video, which enhances the enjoyment of digital entertainment in the home. In the future, the company’s optical storage technology, when combined with Stream Machine’s video compression technology, will provide Cirrus with a more comprehensive solution and a superior integration roadmap compared with its competitors.”

Mr. Canning, who reports to Mr. French, and 42 U.S.-based employees will relocate from their offices in Milpitas, Calif., to the existing Cirrus Logic facility in Fremont, Calif. Stream Machine will also eventually consolidate its China operations into the existing Cirrus facilities in Shenzhen and Beijing.
