Synopsys Securities Suits Drive Toward Dec. 30 Lead‑Plaintiff Deadline as Firms Court Investors

Overview

• Shareholder law firms including DJS, Schall, Rosen, Frank R. Cruz, KSF, and Faruqi issued new notices urging Synopsys investors to contact counsel before the December 30 deadline.
• The complaints allege that an increased focus on AI customers requiring added customization deteriorated the economics of the Design IP business, rendering certain public statements misleading.
• Plaintiffs point to Synopsys’s September 9, 2025 results—$1.740 billion in revenue, $242.5 million in net income, and $426.6 million in Design IP revenue—followed by a 35.8% share-price drop the next day.
• The first-filed case is Kim v. Synopsys in the Northern District of California, with related actions including New England Teamsters Pension Fund v. Synopsys that expanded the alleged class period.
• Some notices also include investors who received Synopsys shares in the Ansys acquisition exchange, and no class has been certified so participation does not require serving as lead plaintiff.
