ITEM 9. REGULATION FD DISCLSOURE On October 27, 2003, Amkor announced its financial results for the three and nine months ended September 30, 2003 and certain other information. The press release, which has been attached as Exhibit 99.1, is incorporated herein by reference. ITEM 12. DISCLOSURE OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION. On October 27, 2003, Amkor announced its financial results for the three and nine months ended September 30, 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 October 27, 2003. 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 THIRD QUARTER 2003 RESULTS RETURNS TO PROFITABILITY FOLLOWING EXTENDED INDUSTRY DOWNTURN EXPECTING CONTINUED GROWTH IN FOURTH QUARTER AND 2004 CHANDLER, AZ. --October 27, 2003 -- Amkor Technology, Inc. (Nasdaq: AMKR) reported third quarter sales of $424 million, up 12% sequentially and up 8% over the third quarter of 2002. Amkor returned to profitability in the third quarter, with net income of $16 million, or $0.09 per share, compared with a loss of $59 million, or ($0.36) per share, in the third quarter of 2002. Amkor's third quarter net income includes a non-cash gain of $10 million, or $0.06 per share, in connection with the reversal of a tax accrual related to tax periods that have closed. Third quarter results also include a charge, with no tax effect, of $2 million, or $0.01 per share, for debt retirement costs in connection with open market purchases of $28 million in 9 1/4% Senior Notes due 2008. Amkor's results for the third quarter of 2002 included $11 million in after-tax charges associated with factory consolidation and operating efficiency initiatives. "This was a landmark quarter, in which we achieved record unit shipments in most of our ten factories and returned the corporation to positive net income after an unprecedented industry downturn," said James Kim, Amkor's chairman and chief executive officer. "We believe the outsourced semiconductor assembly and test industry is poised for a period of sustainable growth, at a rate that will outpace the semiconductor industry. We are encouraged that strengthening customer forecasts may partially offset the seasonal weakness typical of our first calendar quarter. Looking broadly at 2004, we are positioning our organization to achieve annual revenues in the neighborhood of $2 billion, and to reach a peak quarterly gross margin of 27% to 30% during the second half of 2004. We remain committed to improve productivity and profitability, maintain strong liquidity, reduce debt and enhance shareholder value," said Kim. "During the third quarter we saw accelerating demand, particularly from customers supplying the cell phone industry, for a wide range of advanced packages, including stacked CSP, ChipArray BGA, MicroLeadFrame(TM) and camera modules," said John Boruch, Amkor's president and chief operating officer. "Business strengthened as the quarter progressed, with a large number of customers over-supporting their forecasts as demand materialized faster than initially projected. As customer forecasts continued to strengthen, we accelerated our investment in leading-edge assembly and test equipment, and now expect total 2003 capital expenditures to exceed $200 million. As previously announced, Amkor's bank credit facility has been modified to accommodate this increased capital budget."

"Third quarter gross margin rose to 23.9% from 19.6% in the second quarter. Third quarter operating margin rose to 11.2% from 6.0% in the second quarter reflecting the positive operating leverage in our business and the continued high utilization of assets supporting our high growth package families," said Ken Joyce, Amkor's chief financial officer. "Over the past two years we have made substantial progress enhancing the profitability of our business by improving operating efficiencies, increasing manufacturing capacity in strategic growth areas and managing costs." "Our liquidity remained solid, with cash and equivalents of $341 million at September 30," said Joyce. "During the quarter we received $19 million as the first scheduled payment of a $38 million receivable from Dongbu relating to the sale in 2002 of 20 million shares of Anam Semiconductor Inc. common stock. The remaining $19 million payment is scheduled for February 2004. In the third quarter we also sold an additional five million shares of ASI for net cash proceeds of $12 million. At September 30, short-term debt totaled $54 million, principally relating to working capital lines of credit supporting our operations in Japan and Taiwan. As noted earlier, during the third quarter we purchased and retired $28 million of our 9 1/4% Senior Notes due 2008." "We are approaching the third anniversary of our successful joint venture with Toshiba, and in January 2004 we will purchase the remaining 40% of the JV with cash payments ranging from $10 million to $15 million. This amount includes a payment of $2 million to terminate our commitment to purchase a tract of land adjacent to the Amkor Iwate facility," said Joyce. Selected operating data for the third quarter of 2003 is included on a separate page of this release. BUSINESS OUTLOOK Our customers' forecasts have continued to build through most of the third quarter. On the basis of these forecasts, we have the following expectations for the fourth quarter: - Sequential revenue increase in the range of 5% to 8%. - Gross margin around 25%. - Net income in the range of 7 to 10 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 $3 million per quarter in foreign tax expense. At September 30, 2003 our company had U.S. net operating losses totaling $400 million expiring between 2021 and 2022. Additionally, at September 30, 2003 we had $53 million of non-U.S. net operating losses available for carryforward, expiring between 2003 and 2012. 2
