Synopsys Securities Suit: Investors Face Dec. 30 Deadline to Seek Lead-Plaintiff Role

Overview

• The putative class action, Kim v. Synopsys, Inc., No. 3:25-cv-09410, is pending in the Northern District of California under Sections 10(b) and 20(a) and SEC Rule 10b-5.
• Investors who bought Synopsys securities from December 4, 2024 through September 9, 2025 are eligible to seek appointment as lead plaintiff by December 30, 2025.
• Multiple firms, including Bleichmar Fonti & Auld, The Schall Law Firm, DJS Law Group, and Bragar Eagel & Squire, are soliciting shareholders to discuss participation.
• The suit cites Synopsys’s September 9, 2025 results disclosing that the IP business underperformed, with Design IP revenue at about $426 million and net income at $242.5 million.
• Shares fell roughly 36% on September 10, 2025 after the disclosure, as plaintiffs allege AI-driven customization degraded Design IP economics and made certain roadmap decisions ineffective.
