Magnachip Semiconductor (MX) 8-K Magnachip Reports Results for Third Quarter 2022

Exhibit 99.1

Magnachip Reports Results for Third Quarter 2022

• Revenue of $71.2 million was within our guidance range. The year-over-year and sequential decline were primarily driven by the supply shortages of OLED wafers in the 2^nd half of this year that impacted design-in projects from our large panel customer in Korea.

• Gross profit margin was 24.2%, below the low end of our guidance range as we recorded a $3.3 million charge to scrap 12-inch wafers as a result of slowing demand caused by elevated smartphone inventories in China.

• GAAP diluted loss per share was $0.38.

• Non-GAAP diluted earnings per share was $0.02.

SEOUL, South Korea, November 2, 2022 — Magnachip Semiconductor Corporation (NYSE: MX) (“Magnachip” or the “Company”) today announced financial results for the third quarter of 2022.

Commenting on the results for the third quarter of 2022, YJ Kim, Magnachip’s chief executive officer stated, “Our Q3 revenue of $71.2 million was within our guidance range. As we mentioned last quarter, our Display business in the 2^nd half is impacted by supply shortages of 28nm 12-inch OLED wafers that impacted design-in projects from our large panel customer in Korea, which are typically given in advance based on future wafer supply allocation. In addition, China covid lockdowns and the dramatic slowdown in consumer spending due to inflationary pressures reduced demand for smartphones and TVs and resulted in an oversupply of channel inventories, particularly in China. Our Power business also slowed due to lower consumer spending.”

YJ Kim continued, “While the global economic situation remains challenging, our balance sheet is strong, and we are focused on executing a recovery of our Display business. During the quarter, we successfully released our new OLED DDIC sample to our new panel customer and we expect to begin mass production in 2023. In addition, due to the global economic slowdown, we are seeing more wafer capacity availability and we are in discussion with multiple foundries to secure capacity and believe that our 2023 wafer supply will be more than two times higher than 2022. As such, we expect to see a significant recovery of Display business in 2023.”

(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, we will provide transitional foundry services to the buyer for foundry products manufactured in our 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 business lines.

(2) 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 our 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 (loss) 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.

Q4 2022 Financial Guidance

The Company’s near-term outlook is being challenged by previous OLED wafer allocation constraints that impacted 2^nd half design-in projects, elevated smartphone channel inventories, a pushout of the initial mass production ramp of our new OLED customer and weakening demand in consumer end markets on growing recession fears and cost increases, including labor, due to inflationary pressures. In addition, we estimate our Q4 revenue will be further negatively impacted by approximately $5 million of foreign exchange hedging instruments. While actual results may vary, looking into the next quarter, Magnachip currently expects:

• Revenue to be in the range of $57 million to $62 million, including about $7 million of Transitional Fab 3 Foundry Services.

• Gross profit margin to be in the range of 26 % to 28%.

Q3 2022 Earnings Conference Call

Magnachip will host a corresponding conference call at 2:00 p.m. PT / 5:00 p.m. ET on Wednesday, November 2, 2022, to discuss its financial results.

We present Adjusted EBITDA and Adjusted Net Income as supplemental measures of our performance. We define Adjusted EBITDA for the periods indicated as EBITDA (as defined below), adjusted to exclude (i) Equity-based compensation expense, (ii) Foreign currency loss, net, (iii) Derivative valuation gain, net, (iv) Inventory reserve related to Huawei, (v) Merger-related costs and (vi) Other charges, net. EBITDA for the periods indicated is defined as net income (loss) before interest income, net, income tax expense (benefit) and depreciation and amortization.

We prepare Adjusted Net Income by adjusting net income (loss) 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. We define Adjusted Net Income for the periods as net income (loss), adjusted to exclude (i) Equity-based compensation expense, (ii) Foreign currency loss, net, (iii) Derivative valuation gain, net, (iv) Inventory reserve related to Huawei, (v) Merger-related costs, (vi) Other charges, net and (vii) Income tax effect on non-GAAP adjustments.

For the three and nine months ended September 30, 2022, Other charges, net includes $2.8 million of one-time employee incentives, in each period, and professional service fees and expenses of $0.2 million and $1.0 million, respectively, incurred in connection with certain strategic evaluations, both of which were offset in part by a $0.5 million gain on sale of certain legacy equipment of the closed back-end line in our fabrication facility in Gumi. For the three and nine months ended September 30, 2021, Other charges, net includes professional service fees and expenses of $0.2 million and $3.4 million, respectively, incurred in connection with the regulatory requests, both of which were offset in part by a $0.7 million legal settlement gain related to certain expenses incurred in prior periods in connection with our legacy Fab 4 (which was sold during the year ended December 31, 2020) and awarded in the third quarter of 2021.
