F5 Investors Urged to Seek Lead Role in Cyber Disclosure Suit as Feb. 17 Deadline Nears

Overview

• Smith v. F5, Inc., No. 2:25-cv-02619, is pending in the Western District of Washington on behalf of investors who bought F5 securities between October 28, 2024 and October 27, 2025.
• Plaintiffs allege F5 delayed or mischaracterized disclosures about an August 2025 intrusion that affected systems tied to BIG-IP, the company’s highest-revenue product.
• F5 said on October 15, 2025 that it learned of the incident on August 9 and described no material operational impact, and the stock fell about 13.9% over the next two trading days.
• On October 27, 2025, F5 reported Q4 and FY2025 results and guided 2026 revenue growth of 0%–4%, citing potential near-term effects from the breach, and shares fell a further 7.8% the next day.
• Hagens Berman, Robbins Geller, and ClaimsFiler with Kahn Swick & Foti are soliciting investors, probing disclosure timing including SEC 4‑business‑day requirements, and noting a February 17, 2026 lead‑plaintiff deadline.
