Amkor Technology, Inc. announced the pricing of a private offering of $1,000,000,000 aggregate principal amount of 0.00% convertible senior notes due 2031, guaranteed on a senior unsecured basis by certain subsidiaries. The company estimates net proceeds of about $981.7 million, or $1,129.0 million if the initial purchasers fully exercise their option to buy an additional $150,000,000 of notes.
Amkor plans to use $49.0 million of the net proceeds for capped call transactions and the remainder for general corporate purposes, including capital expenditures. The initial conversion rate is 9.4013 shares per $1,000 principal amount, implying an initial conversion price of about $106.37, a 52.5% premium to the $69.75 share price on April 30, 2026. A related capped call has an initial cap price of $139.50 per share, a 100.0% premium to that same price.
Amkor Technology, Inc. plans to offer $1,000,000,000 aggregate principal amount of convertible senior notes due 2031 in a private placement to qualified institutional buyers. The notes will be senior, unsecured obligations, fully and unconditionally guaranteed by certain subsidiaries that guarantee Amkor’s 5.875% senior notes due 2033.
Initial purchasers are expected to receive an option to buy up to an additional $150,000,000 of notes within 13 days of first issuance. The notes will pay semi-annual interest, mature on July 15, 2031, and may be converted by holders in specified circumstances, with Amkor settling conversions in cash and, if applicable, common stock.
Amkor may redeem the notes in cash on or after May 15, 2029 if its stock trades above 130% of the conversion price and certain conditions are met. The company plans to use part of the net proceeds to fund capped call transactions designed to reduce potential dilution upon conversion, and the remainder for general corporate purposes including capital expenditures.
