Term Loan

On March 26, 2024, Magnachip Semiconductor, Ltd., a Korean limited liability company (“MSK”) and indirect wholly owned subsidiary of the Company, executed a Standard Credit Agreement (together with its General Terms and Conditions, the “Loan Agreement”) with Korea Development Bank (“KDB”). In connection with the Loan Agreement, on March 26, 2024, MSK entered into a Kun-Pledge (Mortgage) Agreement (the “Pledge Agreement”) with KDB pursuant to which MSK pledged its real property and buildings located in Gumi, Korea (“Fab 3 properties”) in favor of KDB.

The Loan Agreement provides for a working capital term loan (the “Term Loan”) of KRW 40,000,000,000 (approximately $29,835 thousand based on the KRW/USD exchange rate of 1,340.7:1 as of March 26, 2024 as quoted by KEB Hana Bank), which was funded in full to MSK on March 26, 2024.

The Term Loan bears interest at a variable rate equal to the 3-month CD rate quoted by KDB, plus 1.21%, which rate is adjusted quarterly. The initial interest rate on the Term Loan was 4.86% per annum. The Term Loan requires monthly interest-only payments and matures on March 26, 2027, at which time the full principal balance will be due and payable. All obligations of MSK under the Loan Agreement and the Term Loan are secured by the Fab 3 properties pursuant to the Pledge Agreement.

As of December 31, 2025, approximately $27,877 thousand aggregate principal amount of the Term Loan was outstanding, bearing interest at a variable rate of 3.78% per annum as of that date.

CAPEX Loans

On December 16, 2024, MSK executed a Standard Credit Agreement (as amended) (together with its General Terms and Conditions, the “Equipment Financing Credit Agreement”) with KDB. In connection with the Equipment Financing Credit Agreement, on December 8, 2024, MSK also amended the Kun-Pledge Agreement (the “Equipment Pledge Agreement”) with KDB, originally executed on or about March 26, 2024, to increase the maximum secured amount and to expand the scope of collateral to include certain machinery and equipment owned by MSK, which are located in its fabrication facility located in Gumi, Korea (“Fab 3 machinery and equipment”).

The Equipment Financing Credit Agreement provides for loans for MSK’s capital expenditures (the “CAPEX Loans”) up to an aggregate of KRW 38,000,000,000 ($26,523 thousand based on the KRW/USD exchange rate of 1,432.7:1 as of December 16, 2024 as quoted by KEB Hana Bank), which have been and will be funded directly to capital expenditure supply vendors by KDB upon the submission of a request form by MSK with the necessary evidence such as purchase agreement, invoice and other documentation, as applicable.

The CAPEX Loans bear interest at a fixed rate quoted by the treasury bond market yield (a six-year Korea treasury bill rate). CAPEX Loans mature in ten years from the initial loan disbursement date (the “Maturity Date”), with an initial two-year (measured from the first loan disbursement date) interest-only payment period during which only interest is paid monthly, followed by eight years of amortizing payments where the principal is repaid in equal installments every three months and interest is paid monthly. The Equipment Financing Credit Agreement contains customary representations of MSK in connection with the execution of the

agreement and with each borrowing of CAPEX Loans and customary terms and conditions for a secured equipment financing loan of this type in Korea. All obligations of MSK under the Equipment Financing Credit Agreement and CAPEX Loans are secured by certain Fab 3 machinery and equipment pursuant to the Equipment Pledge Agreement.

During 2025, under its existing Equipment Financing Credit Agreement with KDB, MSK entered into three CAPEX Loans in the aggregate principal amount of KRW 23,995,000,000, consisting of (i) KRW 9,520,000,000 on June 26, 2025, (ii) KRW 5,075,000,000 on September 26, 2025, and (iii) KRW 9,400,000,000 on December 30, 2025 (approximately $16,722 thousand in the aggregate based on the KRW/USD exchange rate of 1,434.9:1 as of December 31, 2025, as quoted by KEB Hana Bank). The CAPEX Loans bear a weighted average interest rate of 2.91% per annum and mature on June 26, 2035.
