Synopsys Shares Plunge on Earnings Miss and Customer Concerns

Financial Performance Falls Short

Synopsys Inc. experienced its most severe single-day stock decline in company history following the release of its third-quarter 2025 financial results. The electronic design automation leader saw its share price collapse by approximately 36 percent, a dramatic market reaction triggered by disappointing performance metrics and troubling disclosures about a critical business relationship.

The software company reported quarterly revenue of $1.74 billion, falling notably short of the $1.77 billion analysts had projected. More significantly, Synopsys posted adjusted earnings per share of $3.39, well below the consensus expectation of $3.80.
