Synopsys, Inc. Faces Class Action Lawsuit Amid Disappointing Q3 2025 Report

In a significant legal development, Synopsys, Inc. (NASDAQ: SNPS) is now embroiled in a securities fraud class action lawsuit. This action, formally referenced as Kim v. Synopsys, Inc., seeks to represent individuals who invested in the company between December 4, 2024, and September 9, 2025. The lawsuit was triggered by the release of the company's Q3 2025 financial results, which revealed severe underperformance in its Intellectual Property (IP) business segment, leading to a 35% drop in stock price on September 10, 2025.

Financial Background

The legal action stems from Synopsys announcing disappointing earnings, reporting an earnings per share (EPS) of just $1.50—a striking 45% decrease compared to the same quarter from the previous year. This plunge was exacerbated by a decline of nearly 8% in the company's Design IP revenues. Investors felt blindsided as Synopsys had previously emphasized the robust growth potential of its Design IP business, which encompasses a range of essential offerings related to silicon design and integration. These offerings included interface and foundation IP, security, and embedded processors designed to facilitate customer adoption of new technology.

The firm initiating the lawsuit, Hagens Berman, posits that Synopsys misled its investors regarding risks associated with its customer base and growth potential. The firm suggests that the shift towards AI-focused clientele, which necessitates greater customization, led to a deterioration in the financial viability of its Design IP business. The lawsuit underscores claims that Synopsys' previously optimistic forecasts were not only misleading but also failed to accurately disclose the obstacles they were facing in achieving sustained revenue growth.

Stock Impact and Investor Reactions

The drastic drop in stock value following the Q3 earnings announcement marks the most significant one-day decline for Synopsys since its initial public offering in 1992. This fall from grace resulted in Hagens Berman monitoring and investigating potential claims regarding the company's misrepresentation of material risks affecting revenue sustainability in its Design IP business segment.

Investors who incurred losses during the specified class period have been encouraged to come forward, with the firm setting a lead plaintiff deadline of December 30, 2025, for individuals wanting to participate in the legal action. Hagens Berman maintains that it is critical for investors to document their losses during this timeframe.

Conclusion

As this lawsuit unfolds, it may attract more attention from regulators and investors keen on shedding light on corporate accountability and transparency. Whistleblowers possessing non-public information related to Synopsys have also been advised to assist in the ongoing investigation, with potential rewards available through the SEC Whistleblower program. Investors impacted by this situation are urged to stay informed as Hagens Berman continues to pursue its investigation into Synopsys' business practices and the efficacy of their revenue growth assertions.

With investors facing the fallout from dwindling shareholder value and possible legal ramifications ahead, this situation invites broader discussions around corporate governance and ethical practices in the fast-evolving tech landscape. Further developments will be closely watched as the narrative continues to unfold in the wake of these troubling Q3 results.
