Changes in US stocks | Customer loss concerns continue to suppress stock prices Synopsys (SNPS.US) plummeted nearly 9%

The Zhitong Finance App learned that on Friday, Synopsys (SNPS.US) plummeted nearly 9% in early trading, the lowest since April 2025, and is now reported at $381.98. According to the news, several people familiar with the matter revealed that the US chip automation design (EDA) giant Synopsys plans to stop providing a set of manufacturing process control software widely used by semiconductor manufacturers around the world. The move is aimed at shifting resources to higher-margin businesses such as artificial intelligence (AI) chip design.

According to people familiar with the matter, the affected products include Equipment Engineering System (EES) and Fault Detection and Classification (FDC). This is a suite of automation software that acts as a semiconductor fab's “central nervous system” to monitor production processes and identify and warn against anomalies before they turn into costly defects. This type of software is regarded by the industry as the “central nervous system” of a fab, and market concerns about loss of customers and revenue gaps continue to weigh down stock prices.
