German semiconductor materials supplier Siltronic reported weaker-than-expected quarterly earnings on Tuesday, citing negative currency impacts and delayed order deliveries to the next quarter. The company also narrowed its full-year 2025 core margin forecast.

Siltronic now expects its 2025 EBITDA margin to range between 22% and 24%, compared to its previous guidance of 21% to 25%.

According to LSEG data, Siltronic’s Q3 EBITDA fell sharply to €65.7 million (~$76.6 million) from €89.4 million a year earlier, missing analysts’ average estimate of €66.6 million.

CEO Michael Heckmeier stated, "As anticipated, Q3 performance was impacted by delayed order deliveries to Q4 and adverse currency effects, temporarily pressuring sales and profitability."

While AI chip demand partially offset weak automotive, PC, and memory chip demand, Siltronic—along with peers like Aixtron and Besi—continues to face subdued demand due to slower-than-expected customer inventory adjustments.

Siltronic, which supplies Infineon, Intel, Samsung, and TSMC, reaffirmed its full-year outlook.
