AMKR · Amkor Technology, Inc.

Amkor Technology, Inc. has completed the issuance of $1.15 billion in aggregate principal amount of 0.00% Convertible Senior Notes due 2031. The Notes were issued pursuant to an Indenture dated May 5, 2026, with U.S. Bank Trust Company, National Association acting as trustee. The offering included the full exercise of the initial purchasers' option to purchase an additional $150 million in principal amount. The Notes will not bear regular interest, though special interest may accrue under specific circumstances relating to reporting failures.

The Notes are convertible into common stock at an initial conversion rate of 9.4013 shares per $1,000 principal amount, equating to an initial conversion price of approximately $106.37 per share. Prior to April 15, 2031, conversions are permitted only upon the occurrence of specified events. The Company retains the right to settle conversions in cash, shares, or a combination thereof. To mitigate potential dilution, Amkor entered into capped call transactions for approximately $56.4 million. These transactions cover the number of shares initially underlying the Notes and have an initial cap price of $139.50 per share, representing a 100% premium over the reference price.

The Notes are fully and unconditionally guaranteed on a senior unsecured basis by the same subsidiaries that guarantee Amkor's existing 5.875% senior notes due 2033. Structurally, the Notes rank senior to subordinated indebtedness, equal to existing senior unsecured debt, and effectively subordinated to secured debt. The Company may redeem the Notes on or after May 15, 2029, provided the last reported sale price of the common stock exceeds 130% of the conversion price for a specified period. Additionally, noteholders have the right to require the Company to repurchase the Notes upon the occurrence of a Fundamental Change at a price equal to the principal amount plus accrued special interest.
