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

A securities class action lawsuit has been filed against F5, Inc. following disclosure of a material cybersecurity breach discovered on August 9, 2025, involving unauthorized access to its BIG-IP source code by a nation-state threat actor. The company initially downplayed the incident's impact on October 15, but subsequently revealed on October 27 that it would significantly reduce 2026 revenue guidance to 0-4% growth due to delayed deals and reduced renewals. The lawsuit challenges the timing and adequacy of F5's disclosures, with the lead plaintiff deadline set for February 17, 2026.
