FFIV INVESTOR ALERT: Hagens Berman Scrutinizing F5 (FFIV) Over Alleged Long

Partner Reed Kathrein Scrutinizing Claims of Best in Industry Security Against Revealed Source Code Theft; Feb. 17 Deadline

SAN FRANCISCO , Jan. 28, 2026 /PRNewswire/ -- National shareholder rights law firm Hagens Berman is issuing notice to investors in F5, Inc. (NASDAQ: FFIV) regarding the February 17, 2026, lead plaintiff deadline in a pending securities class action against the company and certain of its executives.

The firm is actively investigating the alleged claims, which allege that F5 executives misled the market regarding the security of its core BIG-IP products. The lawsuit alleges that while F5 touted its comprehensive security platform, the truth emerged in October 2025: a sophisticated nation-state threat actor had allegedly maintained long-term persistent access to F5's systems , exfiltrating sensitive source code . This breach and the subsequent 2026 revenue guidance cut triggered a series of crashes wiping out over $2 billion in market value.

"We are investigating if F5 unduly delayed in disclosing a material cybersecurity incident," said Reed Kathrein , the Hagens Berman partner leading the firm's investigation of the alleged claims in the pending suit.
