CHANDLER, Ariz., May 4 -- Amkor Technology, Inc. (Nasdaq: AMKR) reported first quarter 2005 sales of $418 million, down 8% sequentially and down 10% from the first quarter of 2004. Amkor's first quarter net loss was $119 million, or ($0.68) per share, and included a provision for legal settlements, with no tax benefit, of $50 million, or ($0.28) per share. For the first quarter of 2004, Amkor's net income was $11 million, or $0.06 per share, and included charges, with no tax benefit, of $2.7 million, or ($0.02) per share, in connection with the prepayment of Amkor's term loan under its senior secured credit facility, and a provision for legal settlement of $1.5 million, or ($0.01) per share.

"Our first quarter operating results reflect a bottoming out of the current semiconductor industry correction and the impact of higher factory costs and operating expenses associated with the capacity expansion and growth initiatives we put in place last year," said James Kim, Amkor's chairman and chief executive officer. "These initiatives, which include our collaboration with IBM and acquisition of Unitive, have created a strong pipeline of new business opportunities. Our goal is to execute successfully on these opportunities and achieve above-industry revenue growth in 2005 and 2006."

"We are encouraged with the way business developed over the first quarter of 2005," said John Boruch, Amkor's president and chief operating officer. "Rising customer forecasts signify to us that the semiconductor industry inventory correction has generally run its course. We have gained major business wins for graphics and gaming applications requiring wafer bump, flip chip assembly, and associated probe and test, and also for CDMA related packaging and test. Our wafer level packaging is ramping to meet Q2 requirements, and the business outlook for Stacked CSP, System-in-package, MicroLeadFrame®, Chip Scale BGA, Memory Cards, and Test is looking strong. We are focused on executing on our business opportunities."

"We are also seeing the results of an increased focus on customer satisfaction, and I'm pleased to note that since mid-2004 we have received recognition awards from a broad range of customers, including Altera, Atheros, Conexant, Infineon, Intel, Qualcomm, QuickLogic, Silicon Labs, Texas Instruments and Volterra," said Boruch. "The transfer of IBM's outsourced assembly and test business is moving forward under our supply agreement."

"First quarter gross margin of 10.4% was at the lower end of our guidance, reflecting the combined impact of an increased fixed cost structure attributable to our 2004 capacity expansion and growth initiatives, seasonally lower revenues, and greater than expected erosion of average selling prices for our products," said Ken Joyce, Amkor's chief financial officer.

"First quarter SG&A expenses included $4 million in legal costs, principally in connection with the mold compound litigation and our patent infringement lawsuit against Carsem," said Joyce. "As previously disclosed, in April 2005 we reached settlements, totaling $45 million, of two cases in the mold compound litigation. We will continue to incur legal expenses as we defend the two remaining cases related to the mold compound litigation and have accrued an additional $5 million loss contingency in connection with these remaining mold compound cases."

First quarter capital expenditures totaled $47 million. "We are investing primarily in key growth areas, such as wafer bumping, flip chip assembly, probe and final test, which are associated with the strategic initiatives we put in place in 2004, and which have translated into major program wins that should drive revenue in the second half of 2005 and into 2006," said Joyce. "We are currently budgeting second quarter capital expenditures of $145 million."

"In our Form 10-K filing, we said that 2005 capital expenditures could reach $300 million and would depend on the performance of our business, the need for additional capacity to service anticipated customer demand and the availability of suitable financing."

Selected operating data for the first quarter of 2005 is included in a separate section of this release before the financial tables.

Business outlook

Our customer forecasts are rising for a broad range of existing package products and also for turnkey flip chip programs that have resulted from our Unitive acquisition and IBM collaboration. We anticipate a stronger-than-normal revenue increase for the second quarter; however profitability will be constrained by the combined effects of continued pricing pressure and a significant ramp in capital and factory resources being deployed to support Q3 and Q4 business expectations. On the basis of current forecasts, we have the following expectations for the second quarter of 2005:

     *  Sequential revenue increase in the range of 10% to 13%.
     *  Gross margin in the range of 12% to 14%.
     *  Net loss in the range of 28 cents to 32 cents per diluted share.

We anticipate recognizing approximately $2 million per quarter in foreign tax expense during 2005. At March 31, 2005 our company had U.S. net operating loss carryforwards totaling $330 million expiring through 2025. Additionally, at March 31, 2005 we had $66 million of non-U.S. net operating loss carryforwards expiring through 2010.

     Prior to March 31, 2005, the Company did not exclude from capital
     expenditures reported in the statement of cash flows, capital
     expenditures that were unpaid and included in accounts payable at each
     balance sheet date.  Thus capital expenditures were reported in the cash
     flow statement on an accrual basis rather than on a cash basis.  This
     presentation caused an over/understatement of cash flows from investing
     activities with an equal over/understatement of cash flows from operating
     activities.  For the three months ended March 31, 2004, the non cash
     amount of capital expenditures was an estimated $39.5 million.  The
     Company has corrected the amounts within the accompanying condensed
     consolidated cash flow statement for the three months ended March 31,
     2004, to reduce net cash provided by operating activities and net cash
     used in investing activities by $39.5 million, compared with the amounts
     previously reported.  The Company is currently evaluating the impact of
     the inclusion of these non cash amounts in the cash flow statement on its
     previously reported financial statements as well as management's
     assessment of the effectiveness of internal control over financial
     reporting.  The ultimate resolution of this matter will not impact the
     Company's previously reported balance sheets; statements of operations
     including its net income (loss), earnings (loss) per share; stockholders'
     equity; or its disclosure of free cash flow.
