Amkor Technology, Inc. Announces Early Participation Results of Tender Offer for a Portion of Its 9.25% Senior Notes Due 2016

Amkor Technology, Inc. (NASDAQ: AMKR) today announced the early participation results of its offer to purchase for cash (the "Offer") up to $175,000,000 aggregate principal amount (the "Maximum Tender Amount”) of its outstanding 9.25% Senior Notes due 2016 (the "Notes”). Based on the count provided by the depositary for the Offer, $123,549,000 aggregate principal amount of Notes were validly tendered (and not validly withdrawn) on or before 5:00 p.m., New York City time on June 7, 2010 (the "Early Tender Date”). The Offer is scheduled to expire at 11:59 p.m., New York City time, on Monday, June 21, 2010, unless extended (the "Expiration Date”).

In accordance with the terms of the Offer, Amkor will accept Notes validly tendered on or before the Early Tender Date, subject to the Maximum Tender Amount, at a purchase price of $1,050 for each $1,000 principal amount of Notes tendered, which includes an early tender premium of $30 per $1,000 principal amount of Notes, plus accrued and unpaid interest on the Notes from June 1, 2010 up to, but not including, the settlement date. Registered holders ("Holders”) of Notes that are validly tendered (and not validly withdrawn) after the Early Tender Date and on or before 11:59 p.m., New York City time, on the Expiration Date and accepted for purchase will receive $1,020 for each $1,000 principal amount of Notes tendered, plus accrued and unpaid interest on the Notes from June 1, 2010 up to, but not including, the settlement date. In the event that the total amount of all Notes validly tendered and not withdrawn on or before the Expiration Date exceeds $175,000,000, Amkor will accept for payment Notes that are validly tendered (and not validly withdrawn) on a pro rata basis from among all of the tendered Notes.

The withdrawal date for the Notes tendered on or before the Early Tender Date was 5:00 p.m., New York City time, on the Early Tender Date. Notes tendered after the Early Tender Date but on or before the Expiration Date may not be withdrawn, provided, however, that if Amkor amends the Offer in a manner that is materially adverse to Holders that have previously tendered, Amkor will extend withdrawal rights for a period it reasonably determines will afford Holders a reasonable opportunity to assess such amended terms.

Amkor expects that the settlement date for the Offer will be June 22, 2010. Payment for the Notes will be made in cash.

The complete terms and conditions of the Offer are set forth in the Offer to Purchase and Letter of Transmittal that have been provided to Holders of Notes.
