F5 Investors Urged to Seek Lead Plaintiff Role as Firms Mobilize Before Feb. 17 Deadline

Overview

• Motions to be appointed lead plaintiff are due February 17, 2026 in the federal securities class action against F5.
• The proposed class period spans purchases from October 28, 2024 through October 27, 2025.
• The complaints allege F5 misled investors about its security posture and revenue outlook while a significant security incident put customers and growth at risk, citing Sections 10(b) and 20(a) and Rule 10b-5.
• Rosen Law Firm, The Schall Law Firm, DJS Law Group, and Faruqi & Faruqi have issued notices inviting investors to contact counsel, and no class has been certified.
• Filings reference F5’s October 27, 2025 guidance linking weakness to the breach and a share drop of about 11% over the following two trading days.
