SILICON LABORATORIES REPORTS RECORD REVENUE

— Company Increases Revenue 11% Year over Year and Achieves Record Profitability —

AUSTIN, Texas — Oct. 28, 2009 — Silicon Laboratories Inc. (Nasdaq: SLAB), a leader in high-performance, analog-intensive, mixed-signal integrated circuits (ICs), today reported third quarter revenue of $125.9 million, a more than 20 percent sequential increase, and an 11 percent increase over peak revenue levels during the same period in 2008. GAAP diluted earnings per share of $0.47 more than doubled sequentially, and non-GAAP diluted earnings per share increased to $0.67. Strong operating performance resulted in record operating income of 21 percent on a GAAP basis and 30 percent on a non-GAAP basis, and more than $50 million in cash flow from operations.

Third Quarter Financial Results

Third quarter revenue of $125.9 million represents a record revenue level for the company. Third quarter GAAP gross margin increased by more than 200 basis points sequentially to 64.4 percent. R&D investment for the period was $25.9 million, and SG&A was $28.6 million.  GAAP diluted earnings per share was $0.47, significantly better than forecasted.

The following non-GAAP results exclude the impact of stock compensation expense. Non-GAAP gross margin increased sequentially by 220 basis points to 64.7 percent. Non-GAAP operating expenses declined sequentially to 35 percent of revenue. On an absolute dollar basis, non-GAAP R&D investment increased to $23.1 million and non-GAAP SG&A expense increased to $20.6 million. Non-GAAP operating income was a record 30 percent. Non-GAAP diluted earnings per share were $0.67, higher than anticipated. The reconciling charges are set forth in the financial tables below.

The quarter ending cash, cash equivalents and investments balance increased sequentially by $67 million, resulting in a total of $403 million. Given the company’s very strong cash position, the Board of Directors approved a share repurchase program to acquire up to $150 million of the company’s outstanding shares through the end of 2010. The program may be executed on the open market or in private transactions, including structured or accelerated transactions, depending on market conditions.

Business Summary

Five of the company’s eight product lines achieved record revenue in the third quarter due to new product cycles and strength at large customers. Notably, the RF business grew in aggregate about 40 percent compared to the same quarter a year ago. An aggressive ramp at the company’s largest customer, the addition of new tier one customers and demand in consumer devices for the AM/FM tuners were largely behind the growth.

The broad-based business was up 15 percent compared to the same period last year, led by a strong rebound in the MCU business. Customer demand improved across the board, with a significant part of the recovery coming from customers shipping into consumer applications.  The timing and power product lines also grew sequentially, adding a significant number of new design wins and expanding the customer base.

“While we are pleased with the success of the business, I strongly believe that there is far more potential for growth,” said Necip Sayiner, president and CEO of Silicon Laboratories. “2009 will be another record year for new product launches, we have an increasing number of developments in the pipeline and we have many more ideas in the funnel. We believe that all of this combined will create new opportunities for us to continue our growth story into 2010 and beyond.”

The company guided fourth quarter revenue to be in the range of $124 million to $129 million, a 25 to 30 percent increase year over year.
