Cirrus Logic Reports Fiscal Q2 2005 Financial  Results

    AUSTIN, Texas--(BUSINESS WIRE)--Oct. 20, 2004--Cirrus Logic Inc.
(Nasdaq:CRUS) today announced financial results for the second quarter
of fiscal year 2005, ended Sept. 25, 2004.
    The company reported second quarter fiscal year 2005 revenue of
$51.3 million, compared with $59.1 million in the prior quarter and
$50.1 million reported in the second quarter of fiscal year 2004.
Second quarter gross margin was 44.7 percent, compared with 53.6
percent in the prior quarter and 51.9 percent in the second quarter
one year ago. Second quarter gross margin included a net charge of
$3.9 million, for excess and obsolete inventory, which had a 7.6
percent negative impact on gross margin. Second quarter fiscal year
2005 combined research and development and selling, general and
administrative expenses were $31.0 million, compared with $31.2
million in the prior quarter and $32.6 million in the second fiscal
quarter of 2004.
    Net loss in the second quarter fiscal year 2005 was $15.1 million,
or a loss of $0.18 per share. The net loss includes $8.0 million of
expense primarily for software write-off, restructuring- and
acquisition-related items. In comparison, the company reported a net
loss of $3.4 million in the prior quarter, which included $5.7 million
of expense for acquisition- and restructuring-related items and a $0.7
million realized gain on the sale of marketable securities. The
company reported net income of $21.1 million in the second quarter of
fiscal year 2004, which included benefits of $31.7 million resulting
from various positive events.
    Total cash and marketable securities at the end of the second
quarter of fiscal year 2005 was $178 million, compared with $198
million at the end of the prior quarter. The decline was primarily due
to an increase in inventory levels built in the first half of fiscal
year 2005, and to a lesser extent, a $4.3 million lease buy out in the
September quarter, as well as facility consolidations and expenses
associated with workforce reductions.
    "As we indicated in our Sept. 23 press announcement, sales of
audio converters for DVD players, predominantly to Chinese
manufacturers, were lower than we had expected due in part to an
industry-wide inventory correction within the supply chain. Demand for
our video ICs was also lower than we anticipated as the emerging DVD
recorder market, particularly in North America, has taken longer to
develop into a consumer mass market. Despite this slower-than-expected
growth in the DVD recorder market, we are encouraged by a number of
design wins with top-tier accounts, such as LG, Samsung and Sony, that
are now entering volume production," said David D. French, president
and CEO of Cirrus Logic Inc.

    Outlook and Guidance

    "Our outlook for the December quarter -- typically a strong
quarter -- is cautious. We believe that the audio converter inventory
imbalance at our customers is in part, but not completely, behind us.
To reduce our IC inventories, we have reduced wafer starts across all
of our major product lines and anticipate lower inventory levels at
our company and in the channel this quarter. Looking ahead, we are
encouraged by the long-term demand trends and our customer design-in
activity for our core, high-margin industrial analog products," said
French.

    Third Quarter FY 05 (ending Dec. 25, 2004)

    --  Revenue is expected to be between $50 million and $55 million,
        with revenue contribution from the following product
        categories:

        --  Analog, which includes the company's audio converter,
            industrial analog, and processor product lines, is
            expected to range between $43 million and $46 million, and

        --  Video is expected to range between $7 million and $9
            million.

    --  Gross margin is expected to range between 51 percent and 53
        percent.

    --  Combined R&D and SG&A expenses are expected to range between
        $28 million and $29 million.
