           Completion of Audit Committee Accounting Review


    --  Revenue of $154.6 million, In-line with Previous Guidance

    --  GAAP EPS of $0.09, Non-GAAP EPS of $0.18

    POCATELLO, Idaho--(BUSINESS WIRE)--Nov. 8, 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 third quarter and nine months ended
September 29, 2007, as well as the completion of its Audit Committee
accounting review. The Company also announced that as a result of the
review, it will be restating its first and second quarter 2007
financial statements, resulting in a negative net adjustment to net
income of approximately $443,000 for the first half of 2007. The
consolidated financial statements and amounts in this press release
have been restated to reflect these changes.

    Financial Results

    Third quarter 2007 revenue was $154.6 million, a decrease of less
than two percent sequentially and three percent compared to the third
quarter of 2006. Gross margin for the third quarter of 2007 was 44.0
percent, flat sequentially and up 20 basis points year over year. On a
non-GAAP basis, gross margin for the third quarter was 44.2 percent,
up 10 basis points sequentially and 30 basis points compared to the
same period in 2006. Non-GAAP gross margin for the third quarter of
2007 and 2006 excludes stock-based compensation expense.

    Operating margin was 8.3 percent in the third quarter of 2007, up
290 basis points sequentially but down 130 basis points year over
year. On a non-GAAP basis, operating margin for the third quarter of
2007 was 15.7 percent, up 250 basis points sequentially and 130 basis
points year over year. Third quarter 2007 GAAP and non-GAAP operating
margins were higher sequentially due to savings realized from
restructuring initiatives in the first and second quarter of 2007,
spending controls during the third quarter, and reduced bad debt
expense after taking the full reserve for the receivable from a former
distributor that went into bankruptcy in the second quarter. Non-GAAP
operating margins for each quarter in 2007 and 2006 exclude
amortization of acquisition-related intangibles, restructuring and
impairment charges and stock-based compensation expense.

    Net income for the third quarter of 2007 was $7.8 million, or
$0.09 per diluted share, compared to net income of $8.6 million, or
$0.10 per diluted share, for the same period in 2006. Non-GAAP net
income for third quarter 2007 was $16.2 million or $0.18 per diluted
share, compared to $14.6 million or $0.16 per diluted share in third
quarter 2006. Third 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 nine months of 2007 was $462.0 million, an
increase of 3 percent compared to the first nine months of 2006. Net
income for the first nine months of 2007 was $19.4 million, or $0.22
per diluted share, as compared to net income of $25.4 million, or
$0.28 per diluted share, for the same period of 2006. Non-GAAP net
income for the first nine months of 2007 was $46.7 million, or $0.52
per diluted share, compared to non-GAAP net income of $44.5 million or
$0.50 per diluted share in the first nine months of 2006. Non-GAAP net
income for the first nine 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 net income and earnings per share for the first nine months
of 2007 also excludes charges related to the first quarter 2007
secondary stock offering, from which the Company received no proceeds.

    "Our third quarter results demonstrate improved operating
leverage," stated Christine King, chief executive officer. "Going
forward we expect to reach our fourth quarter 46 percent gross margin
target and we believe that the actions we've taken will enable us to
further demonstrate operating leverage improvements despite a flat
revenue outlook."

    The Company generated cash from operations during the third
quarter of $23.5 million, bringing cash at the end of the quarter to
$89.3 million, a sequential increase of $11.5 million. Capital
expenditures during the quarter 2007 were $15.5 million.

    Audit Committee Review Completed

    As previously announced in the Company's October 24, 2007 press
release, the Audit Committee of the Board of Directors, which is
comprised solely of independent directors, reviewed the Company's
February 2007 standard cost valuation of inventories and related
issues. The Audit Committee's review was conducted with the assistance
of independent accounting and legal advisors.

    The Audit Committee has completed its review, and as a result, the
Company, in consultation with its independent registered public
accounting firm, has decided to restate its consolidated financial
statements for the first and second quarters of fiscal year ended
December 31, 2007. In connection with the February 2007 standard cost
valuation the Audit Committee review found that the Company made
errors in certain aspects of the standard cost process. In addition,
in the course of its review, the Audit Committee found system coding
issues that resulted in certain errors in the Company's recording of
inventory value. The total adjustment amount was a decrease to net
income of approximately $443,000 for the first half of 2007, comprised
of an increase of approximately $208,000 for the first quarter ended
March 31, 2007 and a reduction of approximately $651,000 for the
second quarter ended June 30, 2007.

    The Audit Committee continues to have confidence in the leadership
of the Company's management and the review resulted in no
recommendation of personnel changes or disciplinary action.

    The Audit Committee conferred with the Company's independent
registered public accounting firm regarding the scope and results of
the review. The Company also informed the Securities and Exchange
Commission of the Audit Committee's review.

    Business Outlook

    --  Revenue in the fourth quarter is expected to be roughly flat
        sequentially.

    --  Fourth quarter gross margin is expected to be approximately 46
        percent.

    --  GAAP diluted earnings per share in the fourth quarter is
        expected to be in the range of $0.09 to $0.11 per diluted
        share. Excluding amortization of acquisition-related
        intangibles, restructuring and impairment charges, stock-based
        compensation expense, and charges related to the Audit
        Committee accounting review, non-GAAP diluted earnings per
        share is expected to be in the range of $0.18 to $0.20.

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

closest GAAP financial measure in the financial statements that
accompany this release. Non-GAAP net income and non-GAAP earnings per
