NEWS RELEASE

SILICON LABORATORIES REPORTS RECORD RESULTS FOR 2004

AUSTIN, Texas – Jan. 24, 2005 – Silicon Laboratories Inc. (Nasdaq: SLAB), a leader in high-performance, analog-intensive, mixed-signal ICs, today reported a 40 percent increase in annual revenues, which totaled a record $456 million for fiscal 2004.  2004 fully diluted GAAP earnings per share of $1.39 were up 62 percent compared to $0.86 in 2003.  Fourth quarter revenues totaled $95.5 million with fully diluted GAAP earnings per share of $0.24.

Financial Results

Under generally accepted accounting principles (GAAP), operating income for the fourth quarter was $16 million, or 17 percent of revenues.  GAAP net income for the fourth quarter was $13 million. Excluding non-cash charges for amortization of deferred stock compensation, adjusted net income for the fourth quarter was $13.8 million, and adjusted diluted net income per share was $0.25.  The company ended fiscal 2004 with cash and short-term investments of $277 million, an increase of over 45 percent versus the year-end balance in 2003.  The reconciling charges are set forth in the reconciliation of GAAP to non-GAAP financial measures table included below.

Business Summary

“2004 was a very strong year for Silicon Laboratories, and I am pleased with the foundation we have built for future growth,” said Dan Artusi, president and chief executive officer of Silicon Laboratories.  “Over the past twelve months we integrated a very successful acquisition, furthering our strategic objective to diversify our products, customers and markets. We also expanded our world-class engineering team, enlarged our IP portfolio and continued to globalize our business.”

Silicon Laboratories expanded design, sales and support offices to 17 locations around the world during the year.  The product portfolio broadened significantly and the number of customers increased to over 3,000.  Cumulative patents either filed or issued increased to more than 450. The number of employees expanded to 588 compared to 486 at the end of 2003.

“Silicon Laboratories is a nimble company. Our focus on scaling our infrastructure wisely to enable sustainable growth combined with a fabless business model enables us to quickly adapt to near-term market fluctuations while staying focused on long term objectives,” Mr. Artusi continued.

For the fourth quarter, the business performed as expected, with both broad-based mixed-signal and mobile handset revenues declining sequentially.  Design win activity remained strong, particularly for the company’s microcontroller products, ProSLIC^® telephony products and Aero^® II RF transceiver.

“We expect our business to grow again in the first quarter as we move past the inventory rebalancing addressed in the second half of 2004,” said Mr. Artusi.  “Market visibility is still limited as we look ahead in 2005.”

The company anticipates revenue of $101 to $105 million in the first quarter of 2005.

Conference Call Today

A conference call discussing the fourth quarter results will follow the release at 4:15 p.m. Eastern Time.  An audio webcast will be available simultaneously on Silicon Laboratories’ website under Investor Relations (www.silabs.com).  A replay will be available after the call at the same website listed above or by calling 866-443-6901 (U.S.) or +1 203-369-1120 (international). These replays will be available through February 14, 2005.

Cautionary Language

This press release contains forward-looking statements based on Silicon Laboratories’ current expectations. The words “believe,” “estimate,” “expect,” “intend,” “anticipate,” “plan,” “project,” “will” and similar phrases as they relate to Silicon Laboratories are intended to identify such forward-looking statements. These forward-looking statements reflect the current views and assumptions of Silicon Laboratories and are subject to various risks and uncertainties that could cause actual results to differ materially from expectations. Among the factors that could cause actual results to differ materially from those in the forward-looking statements are the following: risks that Silicon Laboratories may not be able to maintain its historical growth; quarterly fluctuations in revenues and operating results; volatile stock price; average selling prices of products may decrease significantly and rapidly, especially for mobile handset products; dependence on a limited number of products and customers; risks associated with shifting market demand from GSM/GPRS to EDGE and WCDMA; difficulties developing new products that achieve market acceptance; risks that Silicon Labs may not be able to manage strains associated with its growth; difficulties managing our manufacturers and subcontractors; difficulties managing international activities; credit risks associated with our accounts receivable; geographic concentration of manufacturers, assemblers, test service providers and customers in the Pacific Rim that subjects Silicon Laboratories’ business and results of operations to risks of natural disasters, epidemics, war and political unrest; product development risks; inventory-related risks; intellectual property litigation risks; risks associated with acquisitions, including the acquisition of Cygnal Integrated Products; the competitive and cyclical nature of the semiconductor industry and other factors that are detailed in Silicon Laboratories filings with the SEC, including the Form 10-K that we anticipate will be filed before the end of February, 2005. Silicon Laboratories disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
