Synopsys suspends all China sales and new orders following U.S. export controls, impacting the semiconductor design software market and sparking a 2.5% stock drop.

Synopsys, a major player in the U.S. semiconductor design software market, has stopped all sales and services in China. This move follows new U.S. export restrictions that went into effect on May 29, 2025, which broadly ban the sale of Synopsys products and services to Chinese customers.

U.S. Export Controls Trigger Sales Freeze

An internal memo obtained by Reuters reveals Synopsys notified its China-based employees about the restrictions. The company has suspended both sales and order fulfillment in China, halting all new orders until further guidance is provided. This policy impacts all clients in China, including global companies’ staff working at Chinese sites, as well as Chinese military users no matter where they are located.

Big Blow to China’s Chip Design Sector

Synopsys, together with Cadence and Siemens EDA, commands more than 70% of the electronic design automation (EDA) market in China. Cutting off access to these essential software tools is expected to severely disrupt Chinese chipmakers who depend on this advanced U.S. technology for their designs.

Company Reaction and Market Impact

In response to the tightened restrictions, Synopsys has pulled its annual and quarterly guidance. The company declined to provide additional comments. Following the news, Synopsys shares dropped about 2.5%, reflecting investor concerns about the fallout from the export controls.
