F5 Investors Pressed to Seek Lead Role in Securities Suit as Feb. 17 Deadline Nears

Overview

• Smith v. F5, Inc., No. 25-cv-02619, is pending in the U.S. District Court for the Western District of Washington.
• The proposed class covers purchasers of F5 securities from October 28, 2024 through October 27, 2025, with lead‑plaintiff motions due February 17, 2026.
• The complaint alleges F5 and certain executives failed to timely disclose a significant security incident, rendering prior statements about business prospects misleading.
• F5 disclosed on October 15, 2025 that a highly sophisticated nation‑state actor had long‑term access and downloaded files from certain systems, including the BIG‑IP product development environment, and on October 27 linked lower fiscal 2026 expectations to breach impacts.
• F5 shares fell nearly 14% after the initial disclosure and nearly 11% after the results and outlook update, as multiple plaintiff firms including Portnoy, Howard G. Smith, Rosen, Robbins Geller, Kahn Swick & Foti, and Faruqi & Faruqi solicit investors, with no class yet certified.
