US Stock Market Move | Customer churn concerns continue to suppress the stock price of Synopsys, Inc. (SNPS.US), with a significant drop of nearly 9%.

On Friday, Synopsys, Inc. (SNPS.US) plunged nearly 9% in early trading, hitting its lowest point since April 2025, now trading at $381.98. According to sources familiar with the matter, the U.S. chip automation design (EDA) giant Synopsys, Inc. plans to discontinue a set of manufacturing process control software widely used by semiconductor manufacturers globally in order to shift resources to higher-profit businesses such as artificial intelligence (AI) chip design. The affected products reportedly include Equipment Engineering System (EES) and Fault Detection and Classification (FDC). These are automated software that serve as the "central nervous system" of semiconductor wafer factories, used to monitor the production process and identify and warn of anomalies before they escalate into costly defects. Such software is seen as the "central nervous system" of wafer factories by the industry, and concerns about customer attrition and revenue shortfall continue to weigh down stock prices.
