Amkor Technology, Inc. has entered into a significant amendment to its existing senior revolving credit facility, originally dated May 9, 2025. The amendment, finalized on June 27, 2025, introduces a new tranche of term loans known as Term A-1 Loans. These loans are secured and guaranteed on a pari passu basis with the existing revolver loans. The Term A-1 Loans amount to an aggregate principal of $500 million, maturing on May 9, 2030, and include annual amortization of 2.5% of the original principal amount for the years 2026 and 2027, increasing to 5% per year thereafter. The interest rates on these loans can be based on either Term SOFR or a Base Rate, adjusted by a margin linked to Amkor's consolidated leverage ratio. The proceeds from these loans will be used to refinance existing debt and support general corporate purposes. This amendment reflects Amkor's strategic financial management and commitment to optimizing its debt structure.
