Silicon Laboratories Announces First Quarter Results

April 25, 2007

AUSTIN, Texas--(BUSINESS WIRE)--April 25, 2007--Silicon Laboratories Inc. (Nasdaq: SLAB), a leader in high-performance, analog-intensive, mixed-signal integrated circuits (ICs), today reported strong first quarter results that exceeded the company's guidance on the top and bottom line.

First Quarter Financial Highlights

First quarter results have almost a full quarter of operations inclusive of the Aero® products sold on March 23rd, which are now classified as discontinued operations. During the first quarter of 2007 (on a non-GAAP basis and including the results from discontinued operations), total revenue increased sequentially to $111.8 million, gross margin was 52 percent, and operating income was $11.4 million, or 10 percent of revenue. Net income on a non-GAAP basis, excluding the gain on the sale of the Aero products, was $10.8 million, or $0.19 per fully diluted share, exceeding the high-end of the guidance range by two cents.

The company's continuing operations made up of its core, mixed-signal business delivered 11 percent year over year revenue growth and totaled $73.8 million. GAAP gross margin for the mixed-signal business increased to 61.5 percent. GAAP operating loss was $3.7 million. Excluding an $11.8 million charge for stock compensation expense, non-GAAP operating income was $8 million or 11 percent of revenue. The GAAP income statement includes income from discontinued operations of $156.3 million, which includes the after-tax gain on the sale of the business, resulting in GAAP net income of $155.6 million and GAAP diluted earnings per share of $2.84. The reconciling charges are set forth in the financial measures table included below.

The company ended the quarter with approximately $666 million in cash, cash equivalents and short-term investments. The company repurchased $13 million of its common stock under its repurchase program during the quarter.

"We executed well this quarter on several strategic objectives, and I believe the progress we made to improve efficiencies and scale our infrastructure appropriately demonstrates our commitment to our target operating model," said Necip Sayiner, president and chief executive officer of Silicon Laboratories. "As a company, we are at a positive inflection point strategically, and we have a business with a profile that is now in sync with the growth and profitability targets we have established."

Mixed-Signal Business Summary

Silicon Laboratories' continuing operations are made up of the mixed-signal business which includes a diverse set of innovative products addressing broadcast, embedded modems, voice over broadband, microcontrollers (MCUs), and timing. During the first quarter, the broadcast, microcontroller, embedded modems and timing product lines increased revenue sequentially while voice products declined.

The company announced several strategic MCU and broadcast products in the first quarter. Silicon Laboratories' new additions to the small form factor MCU family enable the company to address cost sensitive applications such as white goods and toys. New broadcast products, including a fully integrated AM/FM receiver, offer additional features and further differentiation in the company's tuner family, improving average selling prices and boosting the company's penetration into portable audio applications.

Business Outlook

For the second quarter of 2007, the company anticipates revenue from continuing operations to be in the range of $74 to $77 million. GAAP net income per fully diluted share is expected to be in the range of $0.10 to $0.13. Non-GAAP net income per fully diluted share, excluding a non-cash charge for stock compensation, is expected to be in the range of $0.22 to $0.25.

limited number of products and customers; difficulties developing new
products that achieve market acceptance; risks that Silicon
Laboratories may not be able to manage strains associated with its
growth (including risks associated with the implementation of its
enterprise resource planning system); dependence on key personnel;
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 and divestitures; the competitive and cyclical nature of
the semiconductor industry and other factors that are detailed in
Silicon Laboratories' filings with the SEC. Silicon Laboratories
