Exhibit 99.1

                 AMIS Holdings, Inc. Reports Revenues
   for Third Quarter 2007 and Announces Review Related to Its 2007
                 Standard Cost Valuation of Inventory


    POCATELLO, Idaho--(BUSINESS WIRE)--Oct. 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 unaudited
revenue for the quarter ended September 29, 2007. The Company also
announced that additional financial information would be released
after the completion of its Audit Committee accounting review
described below.

    Third quarter 2007 revenue was $154.6 million, a decrease of less
than 2 percent sequentially and 3 percent compared to the third
quarter of 2006. Revenue by end market during the third quarter was:

    --  Automotive -- $44.0 million or 28 percent of total revenue,
        down 1 percent sequentially due to a slower European summer
        season, but up 13 percent year over year;

    --  Medical -- $21.4 million or 14% of total revenue, down 16
        percent sequentially and 24 percent year over year due to the
        expected weakness in the implantable and glucose metering
        sub-markets;

    --  Industrial -- $39.3 million or 25 percent of total revenue, up
        2 percent sequentially due to strength in bookings, especially
        in the security market, but down 6 percent year over year;

    --  Mil/Aero -- $11.7 million or 8 percent of total revenue, down
        6 percent sequentially but up 11 percent year over year due to
        normal third quarter seasonality;

    --  Communications and Computing -- $12.4 million or 8 percent and
        $15.8 million or 10 percent of total revenue, respectively, up
        over 5 percent sequentially in each market due to a rebound in
        overall communications and computing demand;

    --  Consumer -- $10.0 million or 7 percent of total revenue, up 9
        percent due primarily to new product introductions.

    Accounting Review

    The Company also announced today that the Audit Committee of the
Board of Directors, which is comprised solely of independent
directors, is reviewing the Company's February 2007 standard cost
valuation of inventories and related issues. The Company has not
determined whether there will be any material impact on its financial
statements as a result of the review. The Company will not be able to
comment further on any aspect of the review or its possible impact
until the Audit Committee completes its work.

    The Company will announce its complete financial results for the
quarter and nine months ended September 29, 2007 as soon as
practicable following the completion of the Audit Committee's work. It
is the Company's target to report these results during the week of
November 5, 2007 and to timely file its Form 10-Q for the quarter,
although the timing and results of the review may affect that
schedule.
