MoSys Revises Revenue Outlook for the Fourth Quarter of 2003

SUNNYVALE, Calif.--(BUSINESS WIRE)--Jan. 22, 2004--MoSys, Inc. (NASDAQ:MOSY) today announced it is reducing its revenue outlook for the fourth quarter of fiscal year 2003 ranging between $3.0 to $3.5 million, from the previously provided estimate of $5.5 to $6.0 million for the quarter. The shortfall occurred due to delays in the recognition of revenue from new customer projects that commenced later in the quarter than the company previously had anticipated based upon such customers' earlier projections.

"We had a strong close to the quarter with total new orders generated in the quarter exceeding $5 million in licensing fees. However, the delay in the commencement of these contracts and the timing of development services does impact our revenue recognition. We were only able to recognize a small percentage of the new orders during the fourth quarter, and expect to recognize substantially all of the associated revenue in 2004," commented Dr. Fu-Chieh Hsu, President and Chief Executive Officer of MoSys. "We are disappointed in the reduction of our revenue estimate for the quarter. We are confident, however, that the strength of our contract pipeline and the increased market acceptance of our technology will translate into future revenue growth for the Company."

MoSys will release its fourth quarter and fiscal year 2003 results for the period ending December 31, 2003 on Wednesday, January 28, after the market closes. Following the release, the Company will host a live audio Web cast and conference call at 5:15 p.m. Eastern Time.

Dr. Hsu and Chief Financial Officer Mark Voll will discuss the company's earnings and operations on the call. Investors and other interested parties may listen to the live Web cast by visiting the investor relations section of the MoSys website at A Web cast replay will also be available on the company's Website.


Founded in 1991, MoSys (NASDAQ: MOSY), develops, licenses and markets innovative memory technologies for semiconductors. MoSys' patented 1T-SRAM technologies offer a combination of high density, low power consumption, high speed and low cost unmatched by other available memory technologies. The single transistor bit cell used in 1T-SRAM memory results in the technology achieving much higher density than traditional four or six transistor SRAMs while using the same standard logic manufacturing processes. 1T-SRAM technologies also offer the familiar, refresh-free interface and high performance for random address access cycles associated with traditional SRAMs. In addition, these technologies can reduce operating power consumption by a factor of four compared with traditional SRAM technology, contributing to making them ideal for embedding large memories in System on Chip (SoC) designs. MoSys' licensees have shipped more than 65 million chips incorporating 1T-SRAM embedded memory technologies, demonstrating excellent manufacturability in a wide range of silicon processes and applications. MoSys is headquartered at 1020 Stewart Drive, Sunnyvale, California 94085. More information is available on MoSys' website at
