NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(TABULAR DOLLARS IN THOUSANDS, EXCEPT SHARE DATA)

1. Business, Basis of Presentation and Significant Accounting Policies

Business

Magnachip

Semiconductor Corporation (together with its subsidiaries, the “Company”) is a designer and manufacturer of analog and mixed-

signal

semiconductor platform solutions for communication, Internet of Things (“IoT”), consumer, computing, industrial and automotive applications.

The Company’s standard products business consists of two business lines: one is the Mixed-Signal Solutions (“MSS”) business line, which comprises the display integrated circuit (“IC”) and power IC businesses that are fabless, and the other is the Power Analog Solutions (“PAS”) business line, which comprises the power discrete business which is an integrated device manufacturing (“IDM”) business.

Display IC products provide panel display solutions to major suppliers of large and small rigid and flexible panel displays, and a wide range of applications, including smartphones, televisions, automotive and IT applications, such as monitors, notebook PCs and tablet PCs, as well as AR/VRs. Power IC products provide power IC solutions to major television suppliers and large panel display suppliers.

The PAS business line produces power management semiconductor products, including power discrete solutions for power management in communication, consumer, computing, servers, automotive and industrial applications.

On September 1, 2020, the Company completed the sale of the Company’s Foundry Services Group business and its fabrication facility located in Cheongju, Korea, known as “Fab 4”, to SK keyfoundry Inc., a Korean company (“SK keyfoundry”). Following the consummation of the sale, the Company provided SK keyfoundry with transitional foundry services associated with its fabrication facility located in Gumi, Korea, known as “Fab 3”, at an agreed upon cost plus

mark-up

(the “Transitional Fab 3 Foundry Services”). The contractual obligation to provide the Transitional Fab 3 Foundry Services ended on August 31, 2023, and the Company is winding down these foundry services and planning to convert portions of the idle capacity to PAS standard products beginning around the second half of 2024. Because these foundry services during the wind-down period are still being provided to SK keyfoundry by the Company using Fab 3 based on mutually agreed terms and conditions, the Company will continue to report its revenue from these foundry services and related cost of sales within the Transitional Fab 3 Foundry Services line in its consolidated statement of operations until such wind-down is completed.

On May 30, 2023, the Company announced a plan to regroup the business lines in its standard products business, originally grouped as Display Solutions and Power Solutions business lines, into MSS and PAS business lines to better align its product strategies (the “Reorganization”). On January 10, 2024, the Company transferred the MSS business line into a newly formed Korean limited liability company named “Magnachip Mixed-Signal, Ltd.” Currently, the MSS business line is primarily operated by Magnachip Mixed-Signal, Ltd., and the PAS business line is primarily operated by Magnachip Semiconductor, Ltd., Magnachip’s already existing Korean operating company. Both companies are indirect wholly owned subsidiaries of the Company.

14. Stock Repurchases

Expanded Stock Repurchase Program

On August 31, 2022, the Board of Directors authorized an expansion of the Company’s previously announced stock repurchase program from $75 million to $87.5 million of its common stock. The Company has already repurchased shares worth $37.5 million under the program through an accelerated stock repurchase agreement on December 21, 2021 with JPMorgan Chase Bank, National Association. The remaining $50 million of the expanded $87.5 million program was planned to be repurchased in the open market or through privately negotiated transactions.

From September 2022 to December 2022, the Company repurchased 1,235,650 shares of its common stock in the open market for an aggregate purchase price of $12.5 million and a weighted average price per share of $10.13 under the stock repurchase program.

During the first half of 2023, the Company repurchased 3,705,443 shares of its common stock in the open market for an aggregate purchase price of $37.4 million and a weighted average price per share of $10.10 under the expanded stock repurchase program. As of the end of June 2023, the Company had completed the repurchase of its common stock under its expanded stock repurchase program.

New Stock Repurchase Program

On July 19, 2023, the Board of Directors authorized a new $50 million stock buyback program. Purchases have been and will be made in the open market or in privately negotiated transactions, depending upon market conditions and other factors.

From August 2023 to December 2023, the Company repurchased 1,730,173 shares of its common stock in the open market for an aggregate purchase price of $13.6 million and a weighted average price per share of $7.84 under the new stock repurchase program.

The following table illustrates the computation of basic and diluted loss per common share for the three months ended March 31, 2024 and 2023:

Diluted loss per share adjusts basic loss per share for the potentially dilutive impact of stock options and restricted stock units. As the Company has reported loss for the three months ended March 31, 2024 and 2023, all potentially dilutive securities are antidilutive and accordingly not considered, therefore basic net loss per share equals diluted net loss per share.

The following outstanding instruments were excluded from the computation of diluted loss per share, as they have an anti-dilutive effect on the calculation:

16. Commitments and Contingencies

Advances to Suppliers

The Company, from time to time, may make advances in form of prepayments or deposits to suppliers, including external foundries, to meet its planned production.
