AMIS Holdings, Inc. Reports Second Quarter 2006 Financial Results;
Revenue Increased 9% Sequentially, Surpassing $150 Million for the
First Time; Six Month Backlog Increased 9% Sequentially to a Record
$184 Million

    POCATELLO, Idaho--(BUSINESS WIRE)--July 27, 2006--AMIS Holdings,
Inc. (Nasdaq:AMIS), parent company of AMI Semiconductor, a leader in
the design and manufacture of integrated mixed-signal solutions, today
reported its financial results for the second quarter and six months
ended July 1, 2006.

    Financial Results

    Second quarter 2006 revenue was $150.7 million, an increase of
nine percent sequentially and 23 percent compared to the second
quarter of 2005. Second quarter 2005 revenue did not include revenues
from the acquisition of the Flextronics semiconductor business, which
occurred in September 2005. Gross margin for the second quarter of
2006 was 45.2 percent, representing a decline of 30 basis points
sequentially and 390 basis points year over year. Gross margin for the
second quarter of 2005 included a 220 basis point net reduction in
cost of revenue that was primarily the result of a capital spending
and employment investment grant from the Belgian government.
    Operating margin was 9.1 percent in the second quarter of 2006, a
decline of 20 basis points sequentially and 670 basis points year over
year. On a non-GAAP basis, operating margin for the second quarter of
2006 was 15.1 percent, flat sequentially, but down 250 basis points
year over year. Non-GAAP operating margin for the second quarter of
2006 and 2005 excludes amortization of acquisition-related intangibles
and restructuring charges. In addition, the Company began expensing
stock options in the first quarter of 2006, and second quarter 2006
non-GAAP operating income excludes $2.1 million of stock-based
compensation expense.
    Net income for second quarter 2006 was $8.1 million, or $0.09 per
diluted share, compared to net income of $11.3 million or $0.13 per
diluted share for the same period in 2005. Non-GAAP net income for
second quarter 2006 was $15.1 million or $0.17 per diluted share,
compared to $12.9 million or $0.15 per diluted share in second quarter
2005. Second quarter 2006 and 2005 non-GAAP net income exclude
amortization of acquisition-related intangibles and restructuring
charges, net of tax effects. Non-GAAP earnings per share for the
second quarter of 2006 also excludes stock-based compensation expense
of approximately $0.02 per diluted share. Non-GAAP net income in the
second quarter of 2005 includes a $2.8 million net reduction in cost
of revenue from the Belgian government grant discussed above as well
as a charge to income taxes of $2.3 million to write-down the
Company's deferred tax assets based on a lower blended U.S. statutory
rate in accordance with SFAS No. 109, "Accounting for Income Taxes."
    Revenue for the first six months of 2006 was $289.3 million, an
increase of 21 percent compared to the first six months of 2005. Net
income for the first six months of 2006 was $16.5 million, or $0.18
per diluted share, as compared to net income of $0.2 million, or $0.00
per diluted share, for the same period of 2005. Non-GAAP net income
for the first six months of 2006 was $29.6 million, or $0.33 per
diluted share, compared to non-GAAP net income of $23.5 million or
$0.27 per diluted share in the first six months of 2005. Non-GAAP net
income for the first six months of 2006 excludes the same items
described above for the second quarter of 2006. Non-GAAP net income
for the first six months of 2005 excludes charges related to debt
refinancing activities in the first quarter 2005 in addition to the
adjustments described above for the second quarter of 2005.
    "I am pleased with the operational improvements we made in the
second quarter," stated Christine King, president and chief executive
officer. "We succeeded in increasing delivery performance which helped
us realize a record level of revenue during the quarter. Though more
work remains to be done to optimize operations, results from the
quarter highlight our ability to grow the top line. I am encouraged by
the strength of our backlog entering the third quarter, and I'm
optimistic about our ability to grow revenue sequentially for the
reminder of the year, driven primarily by anticipated growth in the
automotive market as well as continued strength in the industrial
market."
    The Company generated operating cash flow during the quarter of
$17.2 million, bringing cash at the end of the quarter to $108.5
million, a sequential increase of $5.6 million. Capital expenditures
during second quarter 2006 were $9.8 million.

    Business Outlook

    "Steady progress is being made in improving our operational
performance," said David Henry, senior vice president and chief
financial officer. "Action plans have been implemented and we expect
continued improvement during the rest of the year. Our guidance for
the third quarter of 2006 is as follows:

    --  Revenue is expected to be up 2 percent sequentially;

    --  Gross margin is expected to be approximately 45 percent;

    --  Non-GAAP operating margin is expected to be approximately 15
        percent;

    --  On a non-GAAP basis, our effective tax rate for the third
        quarter is expected to be 17 to 19 percent;

    --  Non-GAAP diluted earnings per share is expected to be
        approximately $0.17;

    --  Pre-tax stock-based compensation expense is expected to be in
        the range of $2.3 - $2.5 million, or approximately $0.02 per
        diluted share;

    --  Capital expenditures for the year are expected to remain at
        approximately eight percent of annual revenues."

Non-GAAP condensed consolidated statements of operations are presented
 because we use them as an additional measure of our operating
 performance and we believe that these excluded charges enhance
 comparability between current and prior periods.  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
 operations 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.
