     Analog Devices Updates Outlook for Fourth Quarter of Fiscal Year 2004


    NORWOOD, Mass.--(BUSINESS WIRE)--Oct. 21, 2004--Analog Devices
(NYSE: ADI) today revised its revenue outlook for the fiscal fourth
quarter ending October 30, 2004 to approximately $630 to $640 million,
down approximately 10% to 12% from the immediately prior quarter.
Earnings per share (EPS) under generally accepted accounting
principles are estimated to be between $0.33 and $0.35 for the fourth
quarter.
    Analog Devices has scheduled a conference call for 8:30 a.m. today
to answer analysts' questions regarding the revised outlook. Investors
may listen via webcast, accessible from www.analog.com. Investors who
prefer to join by telephone may call 706-634-7193 ten minutes before
the call begins and provide the password "ADI."
    "Order rates did not improve in the quarter as we had expected,"
said Mr. Jerald G. Fishman, President and CEO. "On August 12, 2004
when we provided guidance for the fourth quarter, we explained that we
had begun to see a general softening of orders, which had reduced
opening backlog to a level that would require approximately 50% turns
(orders received and shipped within the quarter) to achieve flat
sequential revenue. August was weak as expected, but the pick-up we
hoped would occur in September and accelerate in October did not
materialize. As a result, we have lowered our revenue outlook."
    Commenting on the end markets, Mr. Fishman continued, "The
majority of the weakness occurred in SEA and Japan and was primarily
in wireless handsets, wireless infrastructure, semiconductor capital
equipment and, to a lesser degree, in consumer products.
    In wireless communications, inventory build-up coupled with
economic constraints imposed by the Chinese government impacted
considerably our sales in the region. ADI's significant market share
in China, while a negative in the very short term, gives us a strong
position from which to grow our revenue in the region as the Chinese
economy stabilizes.
    In semiconductor capital equipment, ADI has always enjoyed a very
significant share of the analog content in automatic test equipment
(ATE). As the short term outlook for the semiconductor market became
more uncertain, our largest ATE customers in the U.S. and Japan cut
back orders, adjusting their inventories to the reality of lower
capital spending in the short term.
    In the consumer market, ADI commands very high market share in a
wide range of consumer electronics products. In the first half of this
year, revenue from consumer customers grew substantially. As consumer
sentiment became more uncertain over the past few months, our consumer
electronics customers moved to adjust their inventories very quickly.
As a result, ADI experienced reduced orders for some products sold
into consumer applications.
    ADI revenue from each of these end markets should increase
substantially year-over-year, but it now seems clear that the hyper
growth we experienced earlier in the year has caused some correction
which we are now experiencing at the end of our fiscal year.
    In the U.S. distribution channel, which represents tens of
thousands of customers in virtually every end market, our revenue will
likely be relatively flat sequentially after growing substantially
earlier in the year."
    Regarding company margins, Mr. Fishman commented, "At these
revenue levels, we expect gross margins should decline only slightly.
Our strategy of aligning with our foundry partners for production of
our most volatile products coupled with the very long life cycles of
our internally produced products and substantial manufacturing cost
reductions during the last cycle, should allow continued strong gross
margins provided the industry outlook does not worsen significantly.
    We anticipate that expenses for the quarter should be down
approximately 2% sequentially due to actions taken to control expenses
as orders weakened and also given that some expenses are variable with
volume. This should provide operating profit before taxes of
approximately 25% and EPS in the $0.33-$0.35 range."
    Regarding various balance sheet items, Mr. Fishman continued,
"Inventories are likely to rise by approximately $30 million as a
result of lower revenue and reductions in inventory at distributors.
Our cash balance for the fourth quarter should remain approximately
flat at $2.7 billion, after repurchasing approximately $137 million of
common stock, spending $40 million in capital expenses, and paying $23
million in dividends."
    ADI will provide an outlook for the first quarter of fiscal year
2005, which ends on January 29, 2005 in the company's scheduled
November 23, 2004 fourth quarter earnings release. Mr. Fishman
provided these general comments regarding the near term outlook, "At a
high level, we see mixed signals for the first fiscal quarter. On the
positive side, ADI has experienced more volatility in our order
patterns than our customers have seen in orders from their own end
customers. This tells us that most of the volatility is related to the
supply chain and only a small fraction is related to long term end
market weaknesses. This behavior is somewhat typical since customers
tend to adjust inventories rapidly as the outlook becomes somewhat
uncertain. Our customers tell us that their business remains healthy
and we believe the design in rates of our newest products remain
strong.
    ADI has already absorbed significant inventory reductions from
many of our largest customers. In particular, feedback from customers
in China indicates inventory levels are low and government constraints
are likely to end later this year or early next year. Overall, while
cancellations were higher than expected early in the quarter, they
have reduced to more normal levels in the past 4 to 6 weeks. Also on
the positive side is the fact that our broad customer base seems to be
stable with inventory in reasonably good shape.
    On the more cautionary side, ADI's backlog is currently below
where it was when the quarter began. Customers are waiting until the
last minute to place orders given their cautionary stance and ADI's
short lead times. Finally, we are heading into the first fiscal
quarter which seasonally has fewer business days due to the holiday
periods."
    Mr. Fishman summarized the company's estimated results for the
fiscal year saying, "Despite the revenue shortfall in the fourth
quarter, ADI's results for the fiscal year should be strong with sales
growth of approximately 29%, well ahead of our model of 20-25%; a
four-point improvement in gross margins for the entire year; and
earnings growth of over 85%, nearly three times our revenue growth."
    The estimated cash flow from operations for fiscal 2004 should be
approximately $750 million before capital expenditures of
approximately $150 million, common stock repurchases of approximately
$137 million, and $75 million in dividend payments. Overall cash
balances should increase by over half a billion dollars in fiscal
2004.
    In conclusion, Mr. Fishman said, "These results continue to
substantiate that high performance analog and DSP remain the best
product spaces in the entire semiconductor industry and over many
years should continue to provide sales and earnings growth well above
industry average levels."
