Silicon Labs First Quarter Results

Business Summary

“Many of the markets we serve are showing strong demand, including VoIP customer premise equipment, notebook computers, and GSM/GPRS handsets,” said Dan Artusi, president and chief executive officer of Silicon Laboratories.  “We believe we are leading the competition in both integration and bill-of-materials savings due to a strong portfolio of first-of-a-kind innovations in CMOS. We believe this lead is allowing us to gain significant market share across our key markets.”

Silicon Laboratories’ revenue growth resulted from solid performance in both the broad-based mixed-signal and mobile handset businesses.  During the quarter, the company also announced two major new product innovations, the C8051F350 analog-intensive, high-performance microcontroller and a 100 percent CMOS power amplifier for GSM/GPRS handsets.  The power amplifier will expand Silicon Laboratories total content in the cellular handset.

Business Outlook

“We expect to experience continued strength across our product lines and further diversification of our customer base during the second quarter,” added Mr. Artusi. “We also intend to continue to invest in R&D to further extend our lead and expand our new product pipeline.”

The company anticipates revenue of $120 million to $123 million in the second quarter of 2004.
