Chip materials supplier Siltronic warns of challenging 2026, knocking shares

German semiconductor wafer maker Siltronic warned on Tuesday its markets would remain challenging in 2026, ‌even as it ‌reported better-than-expected preliminary results for the fourth quarter aided by order timings.

Shares of the Munich-based company fell 4.4% by ‌0840 GMT.

Siltronic said it was too early to give detailed guidance for 2026, citing the first full-year impact from the closure of its Burghausen fabrication plant, pressure on prices and impact from a weak U.S. dollar. The pull-forward of some orders into the fourth quarter will also weigh on demand early this year.
