Join the Synopsys (SNPS) Securities Class Action Lawsuit

Shamis & Gentile P.A., one of the nation's premier class action law firms specializing in securities fraud cases, is investigating potential claims against Synopsys, Inc. (SNPS)

If you purchased or otherwise acquired Synopsys, Inc. securities between December 4, 2024 and September 9, 2025, you may be eligible to join this class action lawsuit and seek compensation for your losses.

About Synopsys

Synopsys is a leading provider of electronic design automation (EDA) software and semiconductor intellectual property (IP). Headquartered in California, the company serves clients worldwide, including major foundries and technology companies.

In recent years, Synopsys has also engaged in significant acquisitions, including a $35 billion deal to acquire Ansys, which closed in July 2025.

The Allegations

The class action lawsuit alleges that Synopsys and certain executives made materially false and misleading statements and failed to disclose adverse facts about the Company’s business, particularly regarding its Design IP segment. According to the complaint, Synopsys shifted its focus toward artificial-intelligence customers that required extensive customization, which negatively affected the profitability of its Design IP business.

It is further alleged that management knew “certain road map and resource decisions” were not achieving their intended results but continued to issue positive statements about Synopsys’s operations and outlook.

According to the complaint, the truth emerged on September 9, 2025, when Synopsys released its third-quarter 2025 results, reporting revenue of $1.74 billion, below prior guidance of $1.755 to $1.785 billion. The Company disclosed a 43% year-over-year decline in net income and a 7.7% drop in Design IP revenue, which represented about one-quarter of total revenue.

Following the announcement, Synopsys stock fell 35.8%, or $216.59 per share, from closing at $604.37 on September 9 to $387.78 on September 10, 2025, resulting in significant losses for investors.

Your Rights and Next Steps

If you purchased or otherwise acquired Synopsys securities during the class period, you have important legal rights. Investors who suffered losses related to the alleged misconduct may be eligible to join the class action as members or to be considered for appointment as lead plaintiff.
