SILICON LABORATORIES RESULTS EXCEED EXPECTATIONS

—Strong Quarterly Performance and Better than Seasonal Outlook—

AUSTIN, Texas — Jan. 25, 2012 — Silicon Laboratories Inc. (Nasdaq: SLAB), a leader in high-performance, analog-intensive, mixed-signal integrated circuits (ICs), today reported fourth quarter revenue of $126.7 million, a 13 percent increase compared to the same period last year.  GAAP and non-GAAP earnings per share of $0.29 and $0.49, respectively, exceeded expectations and represented solid double-digit sequential growth.

Financial Highlights

Business trends were robust throughout the quarter, with new product cycles driving revenue upside.  Solid operating performance also translated to better than anticipated profitability.

Fourth quarter revenue increased more than 6 percent sequentially to $126.7 million. GAAP gross margin was 60.9 percent.  R&D investment increased to $34.7 million, and SG&A was flat at $27.3 million.  Operating income improved meaningfully from the same period last year to 12 percent. GAAP net income was 10 percent of revenue for the quarter. Diluted GAAP earnings of 29 cents represented a 12 percent increase compared to the third quarter.

The following non-GAAP results exclude the impact of stock compensation expense and certain other one-time items. Gross margin remained stable at 61.2 percent.  R&D investment increased to $29.6 million due primarily to increased tape out activity, and as planned, SG&A remained flat at $22.5 million. Operating income improved to 20 percent of revenue, and net income improved to 17 percent of revenue. The solid operational performance resulted in diluted earnings per share of 49 cents, an 11 percent sequential increase, and well above guidance.  The company ended the quarter with $325 million in cash, cash equivalents and investments due to continued healthy cash flow from operations.

Reconciling charges are set forth in the financial measures table included below.

Business Highlights

Fourth quarter revenue upside was driven by new product cycles in video and touch controllers, as well as better than anticipated demand for SLIC devices and many of the company’s Broad-based products.

The company’s video products exceeded the full year revenue target and exited the year positioned to further expand its strong market share position as customers ramp 2012 TV models into production. iDTVs featuring the company’s latest generation products were on display at the Consumer Electronics Show, demonstrating the form factor and performance advantages available when using Silicon Labs silicon tuner technology.

Similarly, the company’s touch controllers designed into mobile handsets exceeded initial forecasts, shipping throughout Europe, China and India during the fourth quarter. This rapid ramp in a major mobile handset platform was strong validation for the company’s touch technology and a good foundation for expanding market share in 2012.

The company’s non-consumer products also delivered solid performance in the quarter, including MCUs, which remained stable, and isolation and wireless products which grew significantly as new customer programs ramped.  Timing products delivered excellent year over year growth again at 30 percent, but slowed in the fourth quarter in conjunction with the near-term weakness in the telecom equipment market.

“We enjoyed a sustained improvement in the strength of bookings as we ended 2011. And with our recent results demonstrating significant share gains, we have a lot to look forward to in 2012,” said Necip Sayiner, president and CEO of Silicon Laboratories. “We believe we have both the diversity to weather any lingering macro weakness and the product cycles to get us back into a mode of consistently outperforming our peers.”

The company expects revenue for the first quarter to be in the range of $120 million to $125 million.
