Financial Results

Fourth quarter 2004 revenue was $123.3 million, a decrease of six percent sequentially and two percent below the fourth quarter of last year.  Gross margin for the fourth quarter of 2004 was 49.1 percent, an increase of 60 basis points sequentially and 370 basis points year over year. 

Operating margin was 10.9 percent in the fourth quarter of 2004, a decrease of 880 basis points sequentially primarily driven by charges for restructuring and in process research and development related to the Dspfactory acquisition which did not occur in the third quarter.  Excluding these and other charges, on a pro forma basis, operating margin was 19.1 percent, a decrease of 80 basis points sequentially and an increase of 180 basis points year over year.

Net income for the fourth quarter of 2004 decreased 55 percent sequentially to $7.3 million, or $0.08 per fully diluted share, compared to net income of $16.2 million, or $0.19 per fully diluted share for the third quarter of 2004 and net income of $3.4 million or $0.04 per fully diluted share in the fourth quarter of 2003.  Pro forma net income in the fourth quarter of 2004 was $14.2 million or $0.16 per fully diluted share, compared to pro forma net income of $16.3 million or $0.19 per fully diluted share in the third quarter of 2004 and pro forma net income of $10.6 million, or $0.12 per fully diluted share in the fourth quarter of 2003. 

Revenue for 2004 increased 14 percent to $517.3 million from $454.2 million in 2003.  Net income for 2004 was $52.4 million, or $0.60 per fully diluted share, compared to a net loss of $0.4 million in 2003, or $(0.84) per share.  Pro forma net income for 2004 was $59.6 million or $0.69 per fully diluted share, compared to pro forma net income of $31.5 million or $(0.27) per share in 2003.   Earnings per share amounts in 2003 were impacted by a preferred stock dividend.  Pro forma operating margin, net income and EPS exclude amortization of acquisition-related intangible assets, in-process research and development, restructuring and impairments, nonrecurring charges and other items, net of the related tax effects.  See related financial highlights in this press release for a reconciliation of GAAP earnings to non-GAAP financial measures.

“Despite a difficult fourth quarter, AMIS achieved record revenues in 2004,” said Christine King, president and chief executive officer.  “Growth in our target markets of automotive, medical and industrial was 19 percent for 2004 compared to 2003, which was offset by weakness in communications, particularly in the second half.  We also increased our three year design win revenue in these target end markets 12 percent year over year from 2003 to 2004.  Finally, during the fourth quarter of 2004, we completed our acquisition of Dspfactory, Ltd., which increases our presence in the medical end market and which helped generate record medical revenue in the fourth quarter.”

Operating cash flow for the fourth quarter was $30.8 million and capital expenditures were $11.3 million.  Cash at December 31, 2004 was $161.7 million, a decrease of $2.7 million sequentially, which includes a $27.2 million cash payment for the Dspfactory acquisition and related expenses.

Business Outlook

“We expect our first quarter 2005 revenue to be down six to eight percent as compared to fourth quarter due to continued weakness in the communications market and an inventory buildup at several key customers,” said David Henry, senior vice president and chief financial officer.  “Based on recent ordering patterns, we believe the first quarter will represent the trough in our 2005 revenues.  The beneficial effect of incremental product mix improvements, which have been a key driver of our gross margin expansion in the second half of 2004, will not recur in the first quarter of 2005.  Additionally, we expect a further decrease in factory utilization in the first quarter.  As a result, we anticipate first quarter gross margins to be down approximately 300 to 400 basis points sequentially.  We expect pro forma operating margins will be down 500 to 600 basis points sequentially, as we will continue to invest in research and development during this challenging market environment.  We anticipate our effective tax rate to be between 10 percent and 12 percent in the first quarter.  Pro forma fully diluted earnings per share in the first quarter is expected to be in the range of $0.10 to $0.12.  Pro forma operating margin and pro forma earnings per share exclude anticipated pre-tax charges of approximately $1.5 to $2.0 million in the first quarter for amortization of acquisition-related intangibles and charges as a result of our previously announced restructuring plan.  We expect capital expenditures for 2005 to be approximately eight percent of annual revenues.  Depreciation and amortization is expected to be about $12.0 million in the first quarter.”
