Synopsys shares experienced a devastating decline of over 34% to approximately $398.43 on September 10, 2025, following disappointing third-quarter fiscal 2025 earnings. The company’s stock collapse is driven by misses on revenue and profit expectations, along with challenges arising from intellectual property (IP) business weakness and China’s export restrictions.
