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

Overview

• The putative class action, Kim v. Synopsys, Inc., No. 3:25-cv-09410, is pending in the U.S. District Court for the Northern District of California.
• The class period covers purchases of Synopsys securities from December 4, 2024 through September 9, 2025.
• On September 9, 2025, Synopsys reported Q3 revenue of $1.740 billion, net income of $242.5 million down 43% year over year, and Design IP revenue of about $426.6 million down 7.7%, with guidance implying at least a 5% full‑year decline for Design IP.
• Shares fell roughly 35.8% to close at $387.78 on September 10, 2025, on unusually heavy trading volume following the disclosure.
• Multiple plaintiff firms are reminding investors that motions to be appointed lead plaintiff are due December 30, 2025, as the complaint asserts Exchange Act Sections 10(b) and 20(a) claims tied to alleged AI-related customization impacts on Design IP.
