Siltronic resolves upon forecast of financial year 2023

Munich, Germany, February 24, 2023 - The Executive Board of Siltronic AG today resolved upon the forecast for 2023. Due to expected inventory adjustments for the next quarters in the value chain after us as well as short-term postponement of delivery volumes of some customers in H1 2023, the Executive Board assumes that sales in Q1 2023 will be approximately 15 percent below Q4 2022. The EBITDA margin in Q1 2023 is expected to be between 30 and 33 percent. For the entire year, the Executive Board anticipates the following development:

• Sales significantly below previous year due to lower volumes and exchange rate effects; an average exchange rate of the Euro against the US dollar of 1.10 instead of 1.05 (average for the year 2022) would have a negative impact on sales of around EUR 65 million. On the other hand, there is a positive effect from slightly rising prices.
• EBITDA margin significantly below previous year; in addition to the above-mentioned influences, inflation-related increases in unit costs of around EUR 50 million contributed to the decline
• Depreciation and amortization due to investments at approximately EUR 220 million
• Significant decline in EBIT
• Tax rate in the mid-single-digit percentage range
• Capital expenditure slightly above previous year. Projects that have already started are to be completed on schedule. The capital expenditures in 2024 will materially decrease in comparison to the ongoing year.
• Net cash flow significantly below previous year
• Earnings per share will be significantly lower

The complete and audited Annual Report 2022 will be published on March 9, 2023.
