Company Delivers Record Revenue for 2010

AUSTIN, Texas--(BUSINESS WIRE)-- Silicon Laboratories Inc. (Nasdaq: SLAB), a leader in high-performance, analog-intensive, mixed-signal integrated circuits (ICs), today reported revenue of $112 million for the fourth quarter and record revenue for the full year of $493 million.

2010 Highlights

Year over year growth was driven by record revenue for the company's broad-based products, which grew by nearly 50 percent over 2009 and represented 35 percent of total revenue for the year.
A sustained focus on R&D resulted in 17 new product family introductions during the year spanning MCUs, Embedded Wireless, Isolation, Human Interface, Timing, Video, AM/FM Radio and Power over Ethernet.
The company achieved a record number of design wins, broadened its sales channel and expanded its design team, all strong building blocks for future growth.
Gross margin on both a GAAP and non-GAAP basis was at record levels for the year resulting from cost improvements and mix shifts to broad-based products.
The company delivered 18 percent GAAP operating income and 26 percent non-GAAP operating income for the year.
Cash generation continued to be very strong, enabling $140 million in share repurchases, two strategic technology acquisitions and a year-end cash, cash equivalents and investments balance of $383 million.

Fourth Quarter Highlights

Fourth quarter revenue of $112 million exceeded guidance and represented a seven percent sequential decrease. The better than anticipated result for the quarter was due to stronger than anticipated demand for the company's broad-based products and the early stages of the company's ramp into iDTVs with its silicon TV tuner.

Fourth quarter GAAP gross margin was 63.5 percent. R&D investment increased to $32.6 million while SG&A decreased again to $27.5 million. Fully diluted GAAP earnings per share were $0.28 for the quarter.

The following non-GAAP results exclude the impact of stock compensation expense. Non-GAAP gross margin was 63.9 percent for the quarter. R&D investment increased sequentially to $28.5 million. SG&A expense declined to $22.8 million. Fully diluted non-GAAP earnings per share were $0.46. The reconciling charges are set forth in the financial measures table included below.

2011 Business Outlook

The company anticipates 2011 will be another growth year, with strong contributions from both the broadcast and broad-based businesses. Specifically, the company expects its video business to ramp and triple in size, while the timing business is expected to deliver high double-digit growth again in 2011. Both product lines are benefiting from new product ramps and an expanding footprint enabling strong market share gains.

"We believe the investments we've been making in our business over the last couple of years will begin delivering a strong return in 2011," said Necip Sayiner, president and CEO of Silicon Laboratories. "Organic new product developments complemented by strategic acquisitions like the SpectraLinear deal we announced today, have given us a platform for continually expanding our share of the market. We expect to benefit from such product cycles and are therefore anticipating a revenue increase of approximately four to nine percent in the first quarter."

The company guided revenue for the first quarter in the range of $116 to $122 million.
