Synopsys, Inc. Faces Major Stock Plunge Due to Foundry Issues

On September 10, 2025, Synopsys, Inc. (NASDAQ: SNPS) is in the spotlight as its stock saw an unprecedented decline of 36%, a record plunge since the company went public in 1992. This dramatic fall was triggered by the company’s Q3 fiscal results for 2025, which revealed significant complications with a key foundry customer. Investors had high hopes for recovery; instead, they were met with an unexpected situation that has prompted scrutiny from multiple angles.

Investors were understandably rattled as Synopsys reported a shocking forecast for Q4 2025. The company guided for GAAP earnings per share (EPS) to range between negative $0.27 and negative $0.16, causing alarm among shareholders. The downturn in performance seems primarily linked to struggles within the company’s IP (Intellectual Property) division, primarily attributed to ongoing challenges with a major customer of theirs.

Previously, Synopsys had reassured its stakeholders that the reduced research and development spending from Intel, their largest client, would not substantially affect their electronic design automation (EDA) software business. They underscored the strength of their agreements with Intel, which are characterized as "committed and non-cancellable." However, it appears that these earlier statements may have downplayed the actual risks involved, stirring up doubts about the company’s commitment to transparent communication.

Following these revelations, the national shareholder rights law firm Hagens Berman has launched an investigation. Their focus is on whether Synopsys potentially misled investors regarding the risks associated with its reliance on a single, major customer, and if any false assurances were provided regarding growth prospects.

Reed Kathrein, a partner at Hagens Berman, stated, "We’re examining whether Synopsys might have misrepresented the concentration risk associated with their high reliance on such a single customer." Investors who have experienced considerable financial losses as a result of this recent downturn are encouraged to step forward, potentially offering vital information that may assist in the investigation.

Moreover, the firm urges individuals with insider knowledge regarding Synopsys to consider leveraging their insights, particularly under the SEC’s Whistleblower program, which incentivizes informative reports with rewards of up to 30% from successful recoveries made by the SEC.

The implications of these unfortunate developments extend beyond just the immediate financial ramifications. Investors are concerned about long-term confidence in Synopsys, especially in the competitive landscape of semiconductor technologies and EDA software. Trust and transparency have become focal points for shareholders; leadership must now work significantly hard to rebuild investor faith.

As the fallout continues, Synopsys will be closely monitored by both investors and analysts alike, which may have lasting repercussions for the firm’s market standing. For those tracking Synopsys, updates from Hagens Berman and other investigations into shareholder rights will be crucial in understanding the full context and future of the company’s performance.
