F5 Investors Urged to Seek Lead Role in Securities Suit Following Nation-State Breach

Overview

• Robbins LLP, Glancy Prongay & Murray, and Hagens Berman are soliciting FFIV shareholders to move for lead-plaintiff status by February 17, 2026.
• The filed case, Smith v. F5, Inc., et al. (No. 2:25-cv-02619), covers purchasers from October 28, 2024 through October 27, 2025 in the Western District of Washington.
• Complaints cite F5’s October 15 disclosure of long-term, unauthorized access by a nation‑state actor to BIG‑IP development systems, including exfiltration of portions of source code and information on undisclosed vulnerabilities.
• F5 later guided fiscal 2026 revenue growth to 0%–4%, attributing weaker outlook to breach-related sales slowdowns, elongated deal cycles, lost projections, and higher remediation costs.
• Shares fell sharply after the initial breach disclosure and again following the October 27 results, which investors allege revealed the business impact more fully.
