ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS. (c) Exhibits. 99.1 Text of Press Release dated January 28, 2004. ITEM 12. DISCLOSURE OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION. On January 28, 2004, Amkor announced its financial results for the three months and year ended December 31, 2003 and certain other information. The press release, which has been attached as Exhibit 99.1 and is incorporated herein by reference, discloses certain financial measures, such as free cash flows, which are considered a non-GAAP financial measure. Generally, a non-GAAP financial measure is a numerical measure of a company's performance, financial position, or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles. We believe free cash flow to be relevant and useful information to our investors in assessing our financial operating results as this measure is used by our management in evaluating our liquidity, our ability to service debt and 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 may not be comparable to similarly titled measures reported by other companies. The non-GAAP measures included in our press release have been reconciled to the nearest GAAP measure as is required under SEC rules regarding the use of non-GAAP financial measures. Exhibit Index: 99.1 Text of Press Release dated January 28, 2004. SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.

EXHIBIT 99.1 [AMKOR TECHNOLOGY LOGO] NEWS RELEASE AMKOR REPORTS FOURTH QUARTER 2003 RESULTS INCREASES REVENUE OUTLOOK FOR FIRST QUARTER AND FULL YEAR CHANDLER, AZ. -January 28, 2004 -- Amkor Technology, Inc. (Nasdaq: AMKR) reported fourth quarter sales of $459 million, up 8% sequentially and up 23% over the fourth quarter of 2002. Amkor's fourth quarter net income was $23 million, or $0.13 per share, compared with a loss of $196 million, or ($1.19) per share, in the fourth quarter of 2002. Amkor's fourth quarter 2003 net income includes a $7 million gain on the sale of a marketable security partially offset by $5 million in debt retirement costs associated with the repurchase of convertible notes. Amkor's $196 million loss in the fourth quarter of 2002 included $172 million in non-cash charges associated with (i) establishment of a $129 million valuation allowance against deferred tax assets; (ii) a $33 million impairment in Amkor's investment in Anam Semiconductor, Inc. and (iii) $10 million of estimated costs to consolidate two factories. For the full year, revenue was $1.6 billion compared with $1.4 billion in 2002. Amkor's net income in 2003 was $2 million, or $0.01 per share, compared with a loss of $827 million, or ($5.04) per share, in 2002. "We have completed a year of significant accomplishment and believe that 2004 will present exceptional growth opportunities for Amkor," said James Kim, Amkor's chairman and chief executive officer. "Our 2003 results exceeded our initial expectations and were achieved during a year in which we realigned our operating structure, enhanced our balance sheet and strengthened our product development, sales and support organizations. These strategic initiatives place Amkor in an excellent position to drive continued expansion of the outsourcing model for semiconductor assembly and test." "Since 2001 we have cautiously managed our business in an environment of economic uncertainty and cloudy visibility," continued Kim. "This environment began to change during 2003 as customer demand improved. We believe the semiconductor industry is now entering a period of strong expansion. We are seeing strength in the communications, computer and consumer markets. During the fourth quarter our customer forecasts continued to strengthen, and we now expect to achieve revenue growth in the first quarter of 2004, which is a significant reversal of what is normally a seasonally down quarter. Historically, a sequential increase in our first quarter sales has always signaled a strong year for Amkor. Last quarter I said we were positioning Amkor to achieve $2 billion in revenue in 2004; I now believe we will exceed $2 billion." "In response to broad-based customer demand we have re-ignited Amkor's growth engine and are aggressively moving to increase production capacity to meet demand that our customers are already forecasting," continued Kim. "We are focused on asserting our leadership position in key package technologies. We have budgeted first quarter capital expenditures of $200 million to accommodate robust customer demand and expand our operational footprint in Taiwan and China. We will most likely spend between $300 and $500 million for 2004."

"We see 2004 as a year of great promise for Amkor. We intend to accommodate growth opportunities while improving our capital structure, and we remain committed to de-levering the balance sheet," said Kim. "Over the past year we've experienced unprecedented demand for stacked CSP, chip scale BGA, system-in-package, MicroLeadFrame(R), camera modules and other advanced package families that are especially well suited for wireless and digital consumer electronic applications," said Bruce Freyman, Amkor's newly appointed president and chief operating officer. "We've also had exceptional demand for several legacy package families, and for strip test. During this period we've significantly increased manufacturing capacity and engineering support for the high-growth areas of our business. We are stepping up our product development and R&D activities to ensure that our packaging and test capabilities continue to keep pace with advances in the front end. We also are working on a variety of innovative design collaborations with several OEMs." "Fourth quarter gross margin was 25%. As our business expansion program moves into high gear in Q1 and Q2, our goal will be to increase production capacity to get ahead of customer demand," said Ken Joyce, Amkor's chief financial officer. "We expect the associated depreciation expenses and to a lesser extent factory operating expenses to put some downward pressure on gross margin in the first quarter of 2004, with minimal impact on operating margin as first quarter SG&A expenses should increase only modestly." "During 2003 we strengthened our capital structure - reducing debt by $129 million and increasing shareholders equity by $147 million through the issuance of common stock. Our 2003 initiatives have yielded annualized interest expense savings of $15 million," said Joyce. "As Jim Kim stated, we expect to grow significantly this year, and to support this robust growth we continue to evaluate strategies to further enhance our capital structure. We are prepared to supplement our cash resources with proceeds from capital market activities depending on the pace of our capital expenditure program," said Joyce. Selected operating data for the fourth quarter and full year 2003 is included on a separate page of this release. BUSINESS OUTLOOK Our customers' forecasts have continued to build through most of the fourth quarter. On the basis of these forecasts, we have the following expectations for the first quarter of 2004: - Sequential revenue increase in the range of 2% to 4%. - Gross margin around 24%. - Net income in the range of 8 to 11 cents per diluted share. The provision for U.S. taxes related to our positive earnings is offset by the use of net operating loss carryforwards. We anticipate recognizing approximately $6 million per quarter in foreign tax expense. At December 31, 2003 our company had U.S. net operating losses totaling $405 million expiring between 2021 and 2023. Additionally, at December 31, 2003 we had $49 million of non-U.S. net operating losses available for carryforward, expiring between 2003 and 2012. Amkor will conduct a conference call on January 28, 2004 at 5:00 p.m. eastern time to discuss the results of the fourth quarter in more detail.
