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-termpersistent 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.

F5, Inc. (FFIV) Securities Fraud Claims: Alleged Infiltration and the Guidance Collapse
- Concealment of Systemic Vulnerabilities and Significant Financial risks : The lawsuit alleges the company falsely touted its best-in-industry security and confidence in its ability to meet and capitalize on the growing security needs for its clientele. In reality, F5 was, at the time, the subject of a significant security incident, placing its clientele's security and F5's future prospects at significant risk.
- Undetected Longterm Persistent Infiltration : On Oct. 15, 2025, F5 revealed that "[i]n August 2025, we learned a highly sophisticated nation-state threat actor maintained long-term, persistent access to, and downloaded files from, certain F5 systems. These systems included our BIG-IP product development environment and engineering knowledge management platforms." This news drove shares down nearly 14% over two trading days, according to the complaint.
- Poor Performance and Dismal Outlook : On Oct. 27, 2025, F5 released disappointing 4Q FY25 results, providing significantly below-market growth expectations for fiscal 2026 due in significant part to the security breach as F5 announced expected reductions to sales and renewals, elongated sales cycles, terminated projections, and increased expenses attributed to ongoing remediation efforts. Defendants also allegedly disclosed that BIG-IP, the product that was the subject of the security breach, is F5's highest revenue product. This news drove the price of F5 shares down $22.83 (-7%) the next day and was followed by several analyst rating and price target downgrades.
