Amkor Technology Announces Notice of Full Redemption of 7.375% Senior Notes due 2018

TEMPE, Ariz.

Amkor Technology, Inc. (Nasdaq: AMKR) today announced that it has issued a notice for the redemption of all $345 million aggregate principal amount of the Company’s outstanding 7.375% Senior Notes due 2018 (the “Notes”) to be effected on June 19, 2015. In accordance with the terms of the indenture governing the Notes, the redemption price will be 101.844% of the principal amount of the Notes, or $1,018.44 per $1,000.00 principal amount thereof, paid in cash. In addition, the Company will pay accrued and unpaid interest on the Notes to, but excluding, the redemption date.

The Company plans to fund the redemption of the Notes with borrowings under the Company’s credit facilities and cash on hand. The new borrowings bear interest at floating rates tied to LIBOR and, based on current interest rates, it is estimated that the redemption would result in potential annualized interest savings of approximately $17 million. The Company also expects to record a one-time charge in the second quarter of 2015 of approximately $9 million for early extinguishment of debt.

A notice of redemption is being sent to all currently registered holders of the Notes by U.S. Bank National Association, the trustee under the indenture governing the Notes. Copies of the notice and additional information relating to the procedure for redemption may be obtained from U.S. Bank National Association by calling 1-800-934-6802 (toll-free).
