SEOUL, South Korea, May 10, 2021 /PRNewswire/ -- Magnachip Semiconductor Corporation (NYSE: MX) ("Magnachip" or the "Company") today announced financial results for the first quarter 2021.

"Magnachip delivered solid quarterly results despite the industry-wide supply constraints. Our revenue came in above the midpoint of the company's Q1 revenue guidance range, driven by strong growth in the Power solutions business. Gross profit margin exceeded the high-end of our expectations due to the improved product mix and higher utilization," said YJ Kim, Magnachip's chief executive officer.

Due to the pending merger with an investment vehicle formed by an affiliate of Wise Road Capital LTD pursuant to a definitive agreement executed on March 25, 2021, Magnachip will not be hosting a quarterly earnings conference call and has suspended the practice of providing forward-looking guidance. Please review the 'Investors' section of the Company's website for the quarterly financial results and SEC filings for the latest updates on the pending transaction.

(1)     Following the consummation of the sale of the Foundry Services Group business and Fab 4 in Q3 2020, and for a period of up to
          three years, the Company will provide transitional foundry services to the buyer for foundry products manufactured in the Company's
          fabrication facility located in Gumi ("Transitional Fab 3 Foundry Services"). Management believes that disclosing revenue of
          Transitional Fab 3 Foundry Services separately from the standard products business allows investors to better understand the
          results of our core standard products display solutions and power solutions businesses.

(2)     In Q1 2021, operating loss of $2.1 million included non-recurring professional fees and certain transaction related expenses of $9.8
          million in connection with a definitive agreement (the "Merger Agreement") that the Company entered into with South Dearborn
          Limited, an exempted company incorporated in the Cayman Islands with limited liability ("Parent"), formed by an affiliate of Wise
          Road Capital LTD, and Michigan Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of the Parent ("Merger
          Sub"). The Merger Agreement provides that, among other things, Merger Sub will be merged with and into the Company (the
          "Merger"), with the Company continuing its corporate existence as the surviving corporation in the Merger and becoming a wholly
          owned subsidiary of Parent.

(3) In Q4 2020, total net income of $66.6 million included one-time recognition of deferred tax benefits of $43.9 million.

(4)     Non-GAAP financial measures are calculated based on the results from continuing operations. Management believes that non-
          GAAP financial measures, when viewed in conjunction with GAAP results, can provide a meaningful understanding of the factors
          and trends affecting Magnachip's business and operations and assist in evaluating our core operating performance. However, such
          non-GAAP financial measures have limitations and should not be considered as a substitute for net income from continuing
          operations or as a better indicator of our operating performance than measures that are presented in accordance with GAAP. A
          reconciliation of GAAP results to non-GAAP results is included in this press release.

We present Adjusted EBITDA and Adjusted Net Income as supplemental measures of our performance.

EBITDA for the periods indicated is defined as Income (loss) from continuing operations before interest expense, net, income tax expense (benefit) and depreciation and amortization. We present Adjusted Net Income by adjusting income (loss) from continuing operations to eliminate the impact of a number of non-cash expenses and other items that may be either one time or recurring that we do not consider to be indicative of our core ongoing operating performance. We believe that Adjusted Net Income is particularly useful because it reflects the impact of our asset base and capital structure on our operating performance.
