Aixtron delivers revenue warning, shares on course for worst day in a year
German chip systems manufacturer Aixtron's annual revenue is expected to drop below last year's level because of a challenging market environment, it warned on Thursday after a 16% slide in operating profit, sending its shares on course for a worst day in a year. U.S. President Donald Trump's threat to impose 25% tariffs on cars, semiconductors and pharmaceuticals, which could disrupt the global supply chain, has raised concerns globally. Aixtron also said it expects first-quarter revenue between 90 million and 110 million euros, down from 118.3 million euros in the same period last year.
