  AMIS Holdings, Inc. Reports Second Quarter 2007 Financial Results

    --  Revenue increased 4 percent sequentially to $157.0 million

    --  GAAP EPS of $0.08, Non-GAAP EPS of $0.18

    --  Record Quarter for Design Wins


    POCATELLO, Idaho--(BUSINESS WIRE)--July 24, 2007--AMIS Holdings,
Inc. (NASDAQ: AMIS) (the "Company"), parent company of AMI
Semiconductor, a leading designer and manufacturer of state-of-the-art
mixed-signal and digital products for the automotive, medical,
industrial, and military/aerospace sectors, today reported its
financial results for the second quarter and six months ended June 30,
2007.

    Financial Results

    Second quarter 2007 revenue was $157.0 million, an increase of
four percent both sequentially and when compared to the second quarter
of 2006. Gross margin for the second quarter of 2007 was 44.9 percent,
representing a decline of 20 basis points sequentially and 30 basis
points year over year. On a non-GAAP basis, gross margin for the
second quarter was 45.0 percent, down 30 basis points sequentially and
down 40 basis points compared to the same period in 2006. Non-GAAP
gross margin for the second quarter of 2007 and 2006 excludes
stock-based compensation expense.

    Operating margin was 6.1 percent in the second quarter of 2007,
which is flat sequentially but a decline of 300 basis points year over
year. On a non-GAAP basis, operating margin for the second quarter of
2007 was 14.0 percent, down 60 basis points sequentially, and down 110
basis points year over year. Second quarter 2007 GAAP and non-GAAP
operating margins were negatively affected by increased general and
administrative expenses that were the result of additional bad debt
charges related to the previously announced financial difficulties of
the Company's former distributor, All American Semiconductor. Non-GAAP
operating margin for the second quarter of 2007 and 2006 excludes
amortization of acquisition-related intangibles, restructuring and
impairment charges and stock-based compensation expense.

    Net income for second quarter 2007 was $7.0 million, or $0.08 per
diluted share, compared to net income of $8.2 million or $0.09 per
diluted share for the same period in 2006. Non-GAAP net income for
second quarter 2007 was $15.8 million or $0.18 per diluted share,
compared to $15.2 million or $0.17 per diluted share in second quarter
2006. Second quarter 2006 and 2007 non-GAAP net income excludes
amortization of acquisition-related intangibles, restructuring and
impairment charges and stock-based compensation, net of tax effects.

    Revenue for the first six months of 2007 was $307.4 million, an
increase of 6 percent compared to the first six months of 2006. Net
income for the first six months of 2007 was $12.1 million, or $0.13
per diluted share, as compared to net income of $16.7 million, or
$0.19 per diluted share, for the same period of 2006. Non-GAAP net
income for the first six months of 2007 was $30.7 million, or $0.34
per diluted share, compared to non-GAAP net income of $29.8 million or
$0.33 per diluted share in the first six months of 2006. Non-GAAP net
income for the first six months of 2007 and 2006 excludes amortization
of acquisition-related intangibles, restructuring and impairment
charges and stock-based compensation, net of tax effects. Non-GAAP
earnings per share for the first six months of 2007 also excludes $0.8
million of pre-tax charges related to the March 2007 secondary stock
offering, from which the Company received no proceeds.

    "During the second quarter we exceeded our revenue and EPS targets
and set another record for design wins as measured by anticipated
three year revenue," stated Christine King, chief executive officer.
"In addition, our operational improvements contributed 100 basis
points to our gross margins which was unfortunately offset by product
mix. Looking ahead, we anticipate flat to lower revenues in the third
quarter due to a weak overall medical market. However, we expect
savings from our operational initiatives to offset this decline and
help us maintain our EPS."

    The Company generated operating cash flow during the quarter of
$11.8 million, bringing cash at the end of the quarter to $77.8
million, a sequential decrease of $1.8 million. Capital expenditures
during second quarter 2007 were $14.6 million.

    Business Outlook

    --  Revenue in the third quarter is expected to be flat to down
        two percent sequentially,

    --  Third quarter gross margin is expected to be approximately 44
        percent; however, the Company expects to exit the fourth
        quarter of 2007 with gross margin at approximately 46 percent,

    --  GAAP diluted earnings per share in the third quarter is
        expected to be in the range of $0.08 to $0.10 per diluted
        share. Excluding amortization of acquisition related
        intangibles, restructuring and impairment charges and
        stock-based compensation expense, non-GAAP diluted earnings
        per share is expected to be in the range of $0.17 to $0.18,

    --  The Company continues to expect full year capital expenditures
        to be approximately nine percent of annual revenues.

    Additional Information Regarding Non-GAAP Financial Measures

    Management provides the non-GAAP financial measures presented in
this release because we use them as an additional measure of our
operating performance and we believe that excluding these charges
enhance comparability between current and prior periods. Please see
the reconciliation of each of these non-GAAP financial measures to its
closest GAAP financial measure in the financial statements that
accompany this release. Non-GAAP net income and non-GAAP earnings per
share should not be considered as alternatives to net income, earnings
per share or other consolidated operational data prepared in
accordance with accounting principles generally accepted in the United
States of America, as indicators of our operating performance or as a
measure of liquidity.

    Forward-Looking Statements

    Statements in this press release other than statements of
historical fact are "forward-looking" statements within the meaning of
the Private Securities Litigation Reform Act of 1995. These
forward-looking statements include our expectation of flat to lower
revenues in the third quarter due to a weak overall medical market and
an unfavorable product mix; anticipated savings from our operational
initiatives to offset revenue decline and maintain our EPS; and
guidance on third quarter 2007 revenue, third and fourth quarter gross
margin, third quarter GAAP and non-GAAP earnings per share, and full
year capital expenditures. These forward-looking statements involve
risks and uncertainties that could cause the actual results to differ
materially from those anticipated by these forward-looking statements.
These risks include the failure to properly execute on anticipated
restructuring plans, the failure to properly and efficiently operate
our manufacturing facilities and to take the actions necessary to
increase our gross margins and avoid manufacturing defects and
unnecessary scrap, our ability to manage the availability, capacity
and quality of our subcontractors, manufacturing underutilization,
changes in the conditions affecting our target markets, fluctuations
in customer demand, timing and success of new products, competitive
conditions in the semiconductor industry, failure to maintain and
improve the quality and effectiveness of our internal controls over
financial reporting, failure to successfully integrate the Flextronics
and NanoAmp Solutions businesses, loss of key personnel, general
economic and political uncertainty, conditions in the semiconductor
industry, and other risks and uncertainties that we identified in
reports filed from time to time with the Securities and Exchange
Commission, including our most recent Annual Report on Form 10-K and
Quarterly Report on Form 10-Q. We do not intend to revise or update
any forward-looking statements to reflect events or circumstances
