FFIV Shareholder Notice: F5, Inc. (FFIV) Faces Securities Class Action Amid Cybersecurity Incident, Questions About Disclosure Timing and Impact on Company’s Business – Hagens Berman

F5, Inc. faces a securities class action lawsuit over a major cybersecurity breach involving a nation-state actor that gained unauthorized access to company systems, including its flagship BIG-IP product, on August 9, 2025. The lawsuit questions whether F5 timely disclosed the incident to investors. The breach revelation on October 15, 2025 caused F5 shares to drop 13.9%, and subsequent guidance showing revenue growth slowing from 10% to 0-4% for 2026 triggered another 7.8% decline.
