German semiconductor materials supplier Siltronic has forecast stagnant sales for 2025 after a 7% decline last year, citing high inventory levels and weak demand in key sectors. The company's shares fell more than 15% following the announcement, continuing a downward trend from 2024. While AI is driving some growth, it has not yet offset lower demand for automotive, PC, and memory chips.

CEO Michael Heckmeier stated that wafer demand is unlikely to recover soon, with the first half of 2025 expected to be weaker than late 2024. Siltronic plans to halt production of smaller silicon wafers at its Burghausen facility by the end of July, which will slightly impact sales but have little effect on earnings. The company also acknowledged that its mid-term targets set for 2028 will not be met, though it did not provide a new timeline.

Analysts reacted negatively to the outlook, with Stifel's Juergen Wagner warning of possible downward revisions to 2025 earnings forecasts. Last week, STMicroelectronics also reported continued weakness in the automotive and industrial chip markets. Siltronic's preliminary 2024 revenue stood at E1.41 billion, slightly above expectations, but the company has cut its dividend. A more detailed financial outlook will be presented in its annual report on 6 March.
