F5, Inc. (FFIV) Cybersecurity Incident-Related Securities Class Action Pending As Adverse Financial Impact Clarified – Hagens Berman

F5, Inc. faces a securities class action lawsuit following disclosure of a material cybersecurity breach discovered on August 9, 2025. The company's BIG-IP source code was compromised by a sophisticated threat actor with persistent access. F5's delayed disclosure and subsequent revelation of significantly reduced 2026 revenue guidance (0-4% growth vs. 10% in 2025) triggered sharp stock declines of 10% and 7% on announcement dates. The lawsuit questions whether management knew about the breach's materiality before public disclosure.
