F5 Investor Lawsuits Intensify as Firms Press Feb. 17 Lead‑Plaintiff Deadline
Plaintiffs focus on possible misstatements about a breach tied to BIG‑IP source code theft, with fallout reflected in lowered 2026 guidance.
Overview
- Hagens Berman highlights a pending securities class action following F5's October 15 and October 27, 2025 disclosures about a material cyber incident and its financial impact.
- Allegations describe a highly sophisticated nation‑state actor with long‑term access to F5 systems, including BIG‑IP development environments and exfiltration of source code.
- F5 shares fell about 10% after the October 15 disclosure and about 7% after the October 27 guidance projecting 0%–4% 2026 revenue growth tied to delayed deals and renewals.
- Rosen Law Firm and the Law Offices of Howard G. Smith urge investors who purchased between October 28, 2024 and October 27, 2025 to consider lead‑plaintiff roles before February 17, 2026.
- The complaints contend investors were misled about security risks and revenue outlook, while firms note that no class has been certified and the allegations remain unproven.
