Q4 2023 Financial Guidance
Amid heightened global geopolitical and macroeconomic uncertainty, we expect Power demand to soften driven by normal Q4 seasonality and inventory correction in industrial end markets.

While actual results may vary, Magnachip currently expects the following for Q4 2023:

• Revenue to be in the range of $50 million to $55 million, including approximately $8 million of Transitional Fab 3 Foundry Services.
• Gross profit margin to be in the range of 22.5% to 24.5%.
