Aixtron Surges to 25-Year High as AI Spurs Demand for Its Tools

Niche chip equipment maker Aixtron SE is cementing its place as the new artificial intelligence darling of Europe’s stock market.

Shares in the German company surged as much as 17%, to an almost 25-year high, after it raised full-year guidance, citing strength in the optoelectronics business. Aixtron makes tools for the production of compound semiconductors, which are used in AI infrastructure because they handle power more efficiently than traditional silicon chips.
