On October 14, FormFactor fell 5.07% in regular trading, trading at $121.58 per share, with turnover of $34.9421 million.

The move came as semiconductor equipment stocks remained under pressure, outweighing the earlier positive effect of FormFactor's strategic collaboration with Teradyne.

Earlier, FormFactor and Teradyne announced a semiconductor testing partnership, under which Teradyne agreed to make a $300 million equity investment in FormFactor. The companies said the deal remains subject to closing conditions and regulatory clearance and is intended to support innovation in semiconductor test, advanced computing, AI infrastructure, and broader semiconductor technologies. However, the latest trading session showed broad sector selling pressure, with Applied Materials falling 3.27%, Lam Research falling 4.09%, KLA falling 2.08%, ASML falling 0.84%, and Teradyne falling 5.81%, indicating that industry-wide weakness was the more immediate driver.
