Siltronic adjusts guidance for the financial year 2024

Munich, Germany, April 26, 2024 - The Executive Board of Siltronic AG today resolved to adjust the forecast for the financial year 2024. With our customers' inventory levels remaining high and recovering at a slower pace than originally forecasted, we are facing a further delay of the market recovery. It is therefore expected that the impact of these elevated inventory levels will determine the remaining year 2024, although visibility remains limited.

As a result, we are affected by postponements of delivery volumes by our customers, particularly in the second half of 2024. Although the installation of the new 300 mm capacities is still on schedule and within the budget, some customer qualifications will take place later in 2024 due to the ongoing weak demand. These qualifications are relevant for the start of the depreciation of the new fab, which is expected to be postponed to Q4 2024.

Against this background, the Executive Board expects the following development for 2024:

• Depending on the further development of the demand weakness, sales are expected to be roughly 10 percent below the previous year due to lower volumes and both slightly negative FX (EUR/USD 1.10) and price effects (previously: in the region of the previous year).
• EBITDA margin expected to be between 21 and 25 percent (previously: in the region of the previous year and additionally burdened by up to 3 percentage points due to ramp costs of the new fab).
• Depreciation and amortization expected to be below EUR 300 million
  (previously: almost double y-o-y).
• The result is a significant decline in EBIT.
• Capital expenditure including intangible assets is expected to be slightly below
  EUR 550 million (previously: below EUR 600 million).
• Net cash flow will significantly improve compared to the previous year but will still be significantly negative.
