Amkor Reports Record Fourth Quarter Sales and Return to Profitability

CHANDLER, Ariz., February 8, 2006 — Amkor Technology, Inc. (Nasdaq: AMKR) reported record fourth quarter sales of $643 million, up 42% from the fourth quarter of 2004 and up 17% from the third quarter of 2005. Amkor’s fourth quarter net income was $54 million, or $0.30 per diluted share, compared with net loss of $36 million, or ($0.21) per share, in the fourth quarter of 2004.

Amkor’s fourth quarter 2005 net income included a gain of $4.4 million on the previously announced sale of Amkor Test Services, a specialty test operation; and severance and separation costs of $3.3 million in connection with corporate realignment activities. These items have no tax effect due to our U.S. net operating loss carryforwards and the related valuation allowance. In addition, we recognized an income tax benefit of $9.9 million associated with the release of reserves for domestic and foreign taxes applicable to prior years.

For the full year 2005, Amkor’s sales were a record $2.1 billion, up 10% over 2004. For 2005, Amkor’s loss was $137 million, or ($.78) per share, and included a provision of $50 million for legal settlements. For 2004, Amkor’s net loss was $38 million, or ($.21) per share.

“During 2005 we began to leverage our 2004 strategic initiatives, and we also experienced a broad-based strengthening of customer demand,” said James Kim, Amkor’s Chairman and Chief Executive Officer. “Our fourth quarter results reflect solid unit growth in strategic product areas, a richer product mix, a firmer pricing environment, and enhanced operating leverage in our newer factories.”

“In 2005 we also began to refocus our organization for long-term success,” said Kim. “This process is centered on enhancing operational effectiveness and financial performance, and includes alignment of our management team under Oleg Khaykin, COO, and Ken Joyce, CFO, both of whom report directly to me. Our goals are to increase profitability and generate levels of free cash flow that will allow us to reduce our debt.”

“During the fourth quarter we successfully increased production in our existing factories as well as our newer operations to support strong demand in several end markets, including wireless communications and consumer electronics,” said Kim. “Our leadership in wafer bumping, wafer level processing, flip chip, 3D packaging and other advanced package and test solutions has created what we believe is a strong pipeline of business. We are focused on optimizing our business opportunities, leveraging our strategic alliance with IBM, and laying the groundwork for expansion in Singapore and China.”

“We have seen strong customer acceptance of our electroplated wafer bumping technology, including our lead-free bump, as well as wafer probe capability, and we expect to continue to strategically expand these resources,” said Kim.

“Fourth quarter revenue and gross margin exceeded guidance due to stronger than expected customer demand; favorable product mix; improved pricing and recovery of increasing material costs; higher capacity utilization; and increasing contribution from our newer factories,” said Ken Joyce, Amkor’s Chief Financial Officer. “As a result, gross margin rose to 24.2% from 16.4% in the third quarter.”

“As we seek to increase profitability, we are undertaking a comprehensive program designed to streamline our corporate-wide support organization and reduce SG&A costs,” said Joyce. “Fourth quarter SG&A expenses included a charge of $3.3 million associated with employee reduction and separation expenses, which we expect to yield annualized savings of around $8 million. We intend to continue this process during 2006 with the goal of not only reducing costs, but also improving operational effectiveness.”

“We expect that legal fees, which have been a major contributor to increased SG&A expenses during the past two years, should be lower now that the mold compound and Carsem IP litigation are substantially complete,” said Joyce.

“Our goal is for 2006 SG&A expenses to be $25 to $30 million lower than in 2005,” said Joyce.

“Fourth quarter capital additions totaled $61 million and were focused on test, chip scale packages and flip chip,” said Joyce. “For 2006 we are currently budgeting capital additions of $300 million, including $50 million to facilitize our new factories in China and Singapore. In addition, we expect to undertake further capacity expansion that would be funded by customers under long-term supply agreements. We are prepared to adjust this estimate if business conditions change in the second half of the year.”

“During the fourth quarter we completed a series of financing initiatives designed to improve our liquidity,” said Joyce. “We completed a NT$1.8 billion (approximately $54 million) 5-year secured term loan with a group of Taiwanese lenders, and we replaced our $30 million secured revolving credit facility with a new $100 million senior secured revolver that is available through November 2009. In addition our chairman, James Kim, and members of his family, subscribed to an offering of $100 million of 6.25% convertible subordinated notes due 2013, the proceeds of which were used to repurchase $100 million of 5.75% convertible notes due June 1, 2006.”

“We believe that these initiatives, together with improved cash flow from business operations, have enhanced our financial flexibility,” said Joyce. “We currently have sufficient resources to retire the remaining ‘06 convertible notes at maturity and based on current forecasts we believe we will have sufficient liquidity available to satisfy the $146 million of 5% convertible notes due March 2007. As previously announced, during the first quarter of 2006 we purchased in the open market $30 million face value of our outstanding $471 million aggregate principal amount of 9.25% Senior notes due February 2008.”

In December 2005, DongbuAnam Semiconductor completed the restructuring of its capitalization. Based on DongbuAnam’s market value at December 31, 2005, we recorded an impairment on our equity investment of $736,000 rather than the $4 million we had originally expected.

At December 31, 2005 Amkor had U.S. net operating losses available for carryforward totaling $385 million expiring through 2025. Additionally, at December 31, 2005, we had $80 million of non-U.S. operating losses available for carryforward, expiring through 2011.

Selected operating data for the fourth quarter and full year 2005 is included in a section before the financial tables.

Business Outlook
First quarter revenues are normally down from 5% to 10%, reflecting a shorter work calendar and seasonal adjustments within the supply chain. However, our customers’ forecasts suggest a less-than-typical decline in business activity for the first quarter.

On the basis of current customer forecasts, we have the following expectations for the first quarter of 2006:

• Revenue in the range of 3% to 5% below the fourth quarter of 2005.

• Gross margin in the range of 21% to 22%.

• Net income in the range of $0.10 to $0.14 per share.

Selected operating data for the fourth quarter and full year of 2005

		4th Quarter	Full Year
•	Capital additions	$61 million	$293 million
	Net increase in related accounts payable	$9 million	$3 million
	Payments for property, plant & equipment	$70 million	$296 million
•	Depreciation and amortization	$64 million	$248 million
•	Free cash flow *	$30 million	($199 million)

* Reconciliation of free cash flow to the most directly comparable GAAP measure:

Net cash provided by operating activities	$100 million	$97 million
Less purchases of property, plant and equipment	($70 million)	($296 million)
Free cash flow from continuing operations	$30 million	($199 million)

	We define free cash flow as net cash provided by operating activities less purchases of property, plant and equipment. Free cash flow is not defined by generally accepted accounting principles. However, we believe free cash flow to be relevant and useful information to our investors in assessing our liquidity, capital resources and financial operating results. Our management uses free cash flow in evaluating our liquidity, our ability to service debt and our ability to fund capital expenditures. However, this measure should be considered in addition to, and not as a substitute, or superior to, cash flows or other measures of financial performance prepared in accordance with generally accepted accounting principles, and our definition of free cash flow may not be comparable to similarly titled measures reported by other companies.
•	Fourth quarter capacity utilization was approximately 90%. We calculate capacity utilization as revenue divided by average revenue generating capacity (RGC) for the quarter. We define RGC as 90% of installed capacity (based on the bottleneck limitations for each production line), using quarterly average selling price.
•	Assembly unit shipments for Q4 2005 were 2.1 billion, up 5% from Q3 2005.
•	Assembly unit shipments for FY 2005 were 7.4 billion, up 4% from 2004.
•	Q4 2005 end market distribution (an approximation based on a sampling of programs with our largest customers):

	Communications	37	%
	Computing	19	%
	Consumer	34	%
	Other	10	%
•	Q4 2005 percentage of revenue:
	Leadframe packages	37	%
	Laminate packages	49	%
	Other	4	%
	Test	10	%
