CHANDLER, Ariz., April 27 -- Amkor Technology, Inc. (Nasdaq: AMKR) reported first quarter sales of $465 million, up 1% sequentially and up 36% over the first quarter of 2003. Amkor's first quarter net income was $12 million, or $0.07 per share, compared with $15 million, or $0.09 per share, in the first quarter of 2003.

Amkor's first quarter 2004 net income includes a pre-tax charge of $2.7 million, in connection with the prepayment of Amkor's term loan under its senior secured credit facility. In the first quarter 2003 Amkor's net income included a loss from continuing operations of $40 million, or ($0.24) per share, which was offset by income of $55 million, or $0.33 per share, in connection with its divested wafer fabrication services business.

"While first quarter revenue came in slightly below our forecasted range, we nonetheless were pleased to achieve sequential revenue growth, in contrast to what is normally a seasonally down first quarter," said James Kim, Amkor's chairman and chief executive officer. "The increase in Q1 revenue and continued growth in our customers' long range forecasts suggest that we are in the midst of a broad-based industry recovery, and we remain confident of exceeding $2 billion revenue in 2004. This recovery, combined with what we believe is an acceleration in the outsourcing of semiconductor assembly and test, presents compelling opportunities for Amkor to strengthen our operational capabilities and expand our customer penetration."

"Due to relative weakness in our cell phone products and production constraints at foundries, first quarter demand for some advanced package products did not materialize as forecast," said Bruce Freyman, Amkor's president and chief operating officer. "During the first quarter we increased capacity in several package products which were on allocation for much of 2003 in order to get ahead of demand, and we are now in a more favorable position to support expected growth of these package products through 2004. We also experienced strong growth in our legacy package products during the quarter, which further suggests that integrated device manufacturers (IDMs) have generally not invested in additional assembly capacity."

"First quarter gross margin of 24% was down 1% sequentially due principally to higher material costs," said Ken Joyce, Amkor's chief financial officer. "We anticipate that second quarter gross margin will remain at 24%, despite higher sales volume, due to higher depreciation and labor costs as we continue to expand production space, add equipment and increase factory workforce in advance of what we expect will be a strong second half. These costs include expenses associated with equipping lines and qualifying new business in our newly acquired facility in Taiwan. We currently expect gross margin to improve in the second half of 2004.

"First quarter SG&A expenses included $5 million in legal costs in connection with the epoxy mold compound litigation. As previously disclosed, this litigation relates to a certain mold compound used in the assembly of various IC packages which is claimed to have caused a number of package failures on the part of our customers. We expect the current level of legal costs will continue through 2004. We believe we have very good defenses to these claims and have asserted our own claims against the supplier of the compound," said Joyce.

"First quarter capital expenditures totaled $171 million, including $41 million associated with our previously announced purchase of a 354,000 square foot assembly and test facility in Taiwan. We continue to invest in key package and test areas where we see long-term growth and are currently budgeting second quarter capital expenditures of $125 - 150 million," said Joyce.

"In March we enhanced the company's liquidity by issuing $250 million in 7 1/8% senior notes due 2011 and using the net proceeds to repay amounts outstanding under our senior secured credit facility and for general corporate purposes," said Joyce. "This provides us with the additional financial flexibility to pursue our growth initiatives.

"In April we sold 10.1 million shares of common stock of Anam Semiconductor, Inc. for cash proceeds of approximately $50 million," said Joyce. "This transaction will result in an after-tax gain of approximately $20 million, or $0.11 per share, which will be included in our second quarter results. The incremental cash will be used to fund ongoing capital investments. Following this sale, our investment in ASI has been reduced to 4.6 million shares, or approximately 4% of the company."

Selected operating data for the first quarter of 2004 is included on a separate page of this release.

Business outlook

Our customer forecasts continue to rise for both advanced and legacy package products, however, it is possible that some customers will experience capacity constraints at their wafer foundries. On the basis of current forecasts, we have the following expectations for the second quarter of 2004:

     --  Sequential revenue increase in the range of 5% to 8%.

     --  Gross margin around 24%.

     --  Net income in the range of 17 to 22 cents per diluted share, which
         includes an after-tax gain of $20 million, or $0.11 per share, from
         the sale of 10.1 million shares of ASI common stock.

The tax rate for the second quarter and full year 2004 is expected to be around 11%. At March 31, 2004 our company had U.S. net operating losses totaling $418 million expiring between 2021 and 2024. Additionally, at March 31, 2004 we had $45 million of non-U.S. net operating losses available for carryforward, expiring between 2004 and 2012.

           property, plant and equipment.  Free cash flow is not defined by
           generally accepted accounting principles, and our definition of

         on the limiting equipment set on each production line), using
         quarterly average selling price.
