ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS. (c) Exhibits. 99.1 Text of Press Release dated July 28, 2003. ITEM 12. DISCLOSURE OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION. On July 28, 2003, Amkor announced its financial results for the three and six months ended June 30, 2003 and certain other information. The press release, which has been attached as Exhibit 99.1, 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. In order to fully assess our financial operating results, management believes that free cash flows are an appropriate measure of 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. 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. 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.

(AMKOR TECHNOLOGY LOGO) News Release AMKOR REPORTS SECOND QUARTER 2003 RESULTS CHANDLER, AZ. - July 28, 2003 -- Amkor Technology, Inc. (Nasdaq: AMKR) reported second quarter sales of $378 million, up 10% sequentially and up 8% over the second quarter of 2002. Amkor's second quarter net loss was $51 million, or ($0.31) per share, compared with a loss of $384 million, or ($2.33) per share, in the second quarter of 2002. Amkor's second quarter loss includes a charge, with no tax effect, for debt retirement costs of $31 million, or ($0.19) per share, principally in connection with the early redemption of $425 million in 9-1/4% Senior Notes due May 2006. Amkor's second quarter 2002 loss included an aggregate charge of $311 million ($298 million, or $1.81 per share, after taxes) for special charges and an impairment associated with Amkor's equity investment in Anam Semiconductor, Inc. Second quarter revenue reflected strong business flow, partially offset by the impact of the May 26 earthquake in northern Japan, which disrupted the flow of fabricated wafers to our Iwate joint venture from Toshiba and other customers whose production facilities were affected. "During the quarter we met our revenue and gross margin guidance despite the business disruption caused by the Japan earthquake and notwithstanding the general impact of SARS on the Asian electronics industry," said James Kim, Amkor's chairman and chief executive officer. "We are encouraged with the near and medium term outlook for the semiconductor industry and the outsourced assembly and test sector. Over the past two years we have undertaken a broad set of initiatives to reduce our cost structure and improve the efficiency of our operations. We currently expect to approach or exceed breakeven net income in the third quarter, and based on long-range customer forecasts, we expect a sequentially stronger Q4. We also agree with the broad analyst community that 2004 should be a year of meaningful recovery in our industry, and therefore expect our business to continue to grow into 2004, subject to normal seasonal patterns." "We continue to see evidence that outsourcing is accelerating as IC suppliers and OEMs focus on companies like Amkor to satisfy their advanced package design, assembly and test requirements," said John Boruch, Amkor's president and chief operating officer. "There is clearly a technology transition occurring at the system level that is fueling demand for our advanced package solutions. Our second quarter business developed as expected, and as our customers' aggregate long-range forecasts strengthened, we accelerated our investment in leading-edge assembly and test equipment."

Amkor reports second quarter 2003 results "Second quarter gross margin of 19.6% reflected the positive operating leverage in our business," said Ken Joyce, Amkor's chief financial officer. "Over the past two years we have made substantial progress increasing the profitability of our business by focusing on improving operating efficiencies while managing costs. During the second quarter of 2003 we enhanced our liquidity and capital structure. We refinanced our secured credit facility on more favorable terms, increasing our term loan from $97 million to $170 million with no significant principal amortization until June 30, 2005 and reducing our revolving line of credit (which remains unused) from $100 million to $30 million. In addition, we took advantage of favorable capital markets by extending the maturity of a significant portion of our long-term debt at a more favorable interest rate by issuing $425 million of 7-3/4% Senior Notes due 2013 and using the proceeds to redeem our $425 million in 9-1/4% Senior Notes due 2006." "Our liquidity remained solid, with cash and equivalents of $346 million at June 30," said Joyce. "Short term debt totaled $49 million, principally relating to working capital lines of credit supporting our operations in Japan and Taiwan." Selected operating data for the second quarter of 2003 is included on a separate page of this release. BUSINESS OUTLOOK Our customers' forecasts have generally been building since the beginning of the year. We expect operating expenses to increase modestly in connection with higher business levels in the second half of the year. On the basis of these factors we have the following expectations for the third quarter: - - Sequential revenue increase in the range of 8% to 10%. - - Gross margin in the range of 21% to 24%. - - Net loss of 2 cents per share to net income of 2 cents per share. Our capital budget for 2003 remains $150 million. We currently anticipate capital expenditures in the third quarter to be approximately $40 million. We will resume the recognition of deferred tax assets when Amkor returns to profitability. We anticipate recognizing approximately $3 million per quarter in foreign tax expense for the remainder of 2003. In connection with the ongoing assessment of probable income taxes and related accruals for prior years, we may recognize a tax benefit during the third quarter of 2003. This potential tax benefit is not included in the above earnings guidance. At June 30, 2003 our company had U.S. net operating losses totaling $425 million expiring between 2021 and 2022. Additionally, at June 30, 2003 we had $50 million of non-U.S. net operating losses available for carryforward, expiring between 2003 and 2012. 2
