ASM International shares plunged after boosting revenue guidance for next year fell short of rosy forecasts. The Dutch group, a key supplier of wafer‑processing equipment for depositing thin films, had raised its outlook in September, but investors had been optimistic after a surge in demand driven by AI.

In September ASM International set a 2027 revenue target of 3.7 billion to 4.6 billion euros, roughly $4.21 billion to $5.24 billion. It later said next‑year revenue would exceed the top end of that range, but analysts had already projected nearly 4.89 billion euros. The revenue guidance aimed to capture the growing need for advanced deposition tools.

Jefferies analysts noted in a client note that there was unlikely to be material upside to the 2027 consensus estimates, and Visible Alpha’s data highlighted the discrepancy between the company’s guidance and market expectations. Despite the upward revision, the guidance still lagged behind the consensus, eroding confidence.

Shares in Amsterdam fell more than 8% on Wednesday, wiping out gains made since January. The decline came amid a wave of investor fervor that pushed global semiconductor stocks to new highs as the race to build artificial‑intelligence infrastructure fuels demand for chips and the tools needed to make them возле.
