SILICON LABORATORIES REPORTS THIRD QUARTER RESULTS

AUSTIN, Texas — Oct. 27, 2010 — Silicon Laboratories Inc. (Nasdaq: SLAB), a leader in high-performance, analog-intensive, mixed-signal integrated circuits (ICs), today reported revenue of $120.2 million for the third quarter, and better than anticipated earnings per share of $0.40.

Financial Highlights

Third quarter revenue of $120.2 million represented a five percent decrease from the same period in 2009. Third quarter GAAP gross margin was 65.5 percent. R&D investment for the third quarter was nearly flat sequentially at $30.8 million.  SG&A expense declined to $28.6 million. GAAP operating income was 16.1 percent. The GAAP tax rate was six percent, resulting in fully diluted earnings per share of $0.40.

The following non-GAAP results exclude the impact of stock compensation expense and other one-time items. Non-GAAP gross margin for the quarter was down slightly as expected to 65.8 percent, but still above the company’s target model. Non-GAAP operating expenses declined to $49.4 million. Specifically, R&D was about flat at $26.4 million and SG&A decreased to $23.0 million.  Non-GAAP operating income totaled 24.7 percent of revenue. Non-GAAP diluted earnings per share were at the high end of revised guidance at $0.53. The reconciling charges are set forth in the financial measures table included below.

Share repurchases during the quarter totaled $40 million, bringing the year-to-date total to $140 million. The company ended the quarter with $365 million in cash, cash equivalents and investments due to continued healthy cash flow from operations.

Business Summary

The revenue decline in the quarter was due in part to demand weakness and inventory

misalignment for the company’s products shipping into consumer-oriented applications. The Access business was down as anticipated. The Broadcast business experienced a market-related slowdown in the company’s Consumer Audio products as well as the expected declines in handsets. The Broad-based business was also impacted by end market weakness, particularly Embedded Mixed-Signal products, which were down sequentially, while Timing products enjoyed another record quarter.

The company continued to secure strategic design wins across its growth businesses, including new wins in wireless, timing, isolation, human interface, microcontroller, consumer audio and video products, providing strong evidence of the company’s ability to return to revenue growth as the end markets recover. New Class D amplifier and human interface products announced during the quarter also represent expansions of the company’s portfolio in key end markets. Research and development hiring and investment continued, with new products in development at a record high.

“While this retreat in revenue is uncharacteristic, we believe the fourth quarter represents a trough, and the composition of the business that will emerge in 2011 will be even more growth oriented,” said Necip Sayiner, President and CEO of Silicon Laboratories. “We’re very optimistic about progress in our emerging video product line and continue to view our Broad-based business as a strategic growth engine in 2011 and beyond.”

The company guided revenue for the fourth quarter in the range of $105 to $111 million.
