On October 9, 2025, Synopsys reported third-quarter results that missed analyst expectations, citing revenue of $1.74 billion and adjusted EPS of $3.39, both below forecasts. The company attributed the shortfall to challenges in its high-margin IP business and operational issues with a major foundry customer, while also providing a cautious outlook for the next quarter due to ongoing IP segment issues and export restrictions affecting China. These developments triggered a sharp negative reaction, with Synopsys stock closing at $438.92 on October 10, 2025, down 9.39% for the day and marking a 36% drop since the earnings release. The magnitude of the decline and coverage by major outlets make this a company-moving event.
