The notes will be fully and unconditionally guaranteed, on a senior, unsecured basis, by each subsidiary of Amkor that currently or in the future guarantees its 5.875% senior notes due 2033 (the "guarantors"). Amkor also expects to grant the initial purchasers of the notes an option to purchase, for settlement within a period of 13 days from, and including, the date the notes are first issued, up to an additional $150,000,000 aggregate principal amount of notes.

The notes will be senior, unsecured obligations of Amkor, will accrue interest payable semi-annually in arrears and will mature on July 15, 2031, unless earlier repurchased, redeemed or converted. Noteholders will have the right to convert their notes in certain circumstances and during specified periods. Amkor will settle conversions in cash and, if applicable, shares of its common stock.
