On October 15, FormFactor fell 6.59% in Regular Trading, trading at $109.53 per share with turnover of $12.53 million.

The move aligns with broad weakness across the Semiconductor Equipment group, which continued to pressure the stock despite the company’s recently announced strategic collaboration with Teradyne.

Earlier disclosures said Teradyne plans a $300 million equity investment in FormFactor as part of a semiconductor test partnership focused on advanced computing, AI infrastructure, and broader test ecosystem innovation. However, the transaction remains subject to closing conditions and regulatory clearance, limiting its near-term support for the shares. On the same day, peer weakness was also evident, with ASML Holding NV falling 2.4%, Applied Materials falling 4.33%, Lam Research falling 5.75%, KLA Corporation falling 4.75%, and AXT Inc falling 11.51%.
