Silicon Laboratories Reports Better Than Expected First Quarter Results and Strong Outlook

CompanyDemonstrates Good Expense Control and Generates Solid Cash Flow
AUSTIN, Texas--(Business Wire)--
Silicon Laboratories Inc. (Nasdaq: SLAB), a leader in high-performance,
analog-intensive, mixed-signal integrated circuits (ICs), today reported first
quarter revenue of $83.7 million. The company`s expense controls, better than
expected revenue and model gross margin resulted in better than anticipated
earnings per share performance and solid cash generation in the quarter.

First Quarter Financial Results

First quarter revenue of $83.7 million declined 16 percent sequentially versus
the original projection of a 20 to 25 percent decline. Strong operating
performance allowed the company to remain profitable on a GAAP basis. First
quarter GAAP gross margin was flat sequentially at 60.5 percent. R&D investment
for the period declined to $26.1 million and SG&A declined to $23.4 million.
GAAP diluted earnings per share was one cent, significantly better than
originally anticipated. Cash flow from operations was nearly $12 million.

The following non-GAAP results exclude the impact of stock compensation expense
and other one-time charges. Non-GAAP gross margin held at the midpoint of the
company`s target range at 61 percent. Non-GAAP operating expenses declined five
percent sequentially to $38.9 million as a result of tight controls over
discretionary spending. Non-GAAP operating income was 14.5 percent at $12.1
million, an excellent result. Non-GAAP diluted earnings per share were $0.22,
considerably better than anticipated. The reconciling charges are set forth in
the financial measures table below.

During the first quarter, accounts receivable returned to normal levels as
demand improved throughout the quarter. Inventory decreased again sequentially
to $23.5 million. The company repurchased $5 million in shares and ended the
quarter with a higher level of cash, cash equivalents and investments at $326
million.

Business Summary

The company`s notable performance during the quarter was due primarily to
several key customers gaining share in their respective markets and new product
cycles.

The Broad-based business increased almost 15 percent year over year driven by
growth in the timing and power businesses. Increasing share and new product
momentum experienced during the first quarter is expected to continue into the
second quarter. The RF business declined less than anticipated due to a strong
ramp of the video demodulator with a major customer, as well as relatively
better handset demand. Handsets represented the dominant share of the audio
revenue, and new design win activity was strong. The Access business declined
sequentially as customers reduced inventory levels. All three businesses,
Broad-based, RF and Access are expected to grow sequentially in the second
quarter.

"With the first quarter behind us, we are feeling good about our business, even
in light of what we recognize is a very weak global economy," said Necip
Sayiner, president and CEO of Silicon Laboratories. "We see Q1 as the cyclical
bottom in terms of revenue and expect to benefit from strong product cycles and
share gains going forward. We believe that our ability to hold margins, sustain
our profitability and generate cash despite the depressed revenue puts us in a
select group of companies well equipped to outperform this year."

For the second quarter of 2009, the company is guiding revenue in the range of
$92 to $97 million.
