In New York and New Orleans a press release by Kahn Swick & Foti reminded investors they have until February 17, 2026 to file lead plaintiff applications in a securities class action against F5, Inc. after F5’s October 27, 2025 fourth quarter results linked weaker fiscal 2026 growth expectations to a security breach affecting its BIG-IP product and the stock fell about 10.9 percent over two days.
KEY FACTS
- Filing deadline February 17, 2026 to seek lead plaintiff status
- Class period purchases from October 28, 2024 through October 27, 2025
- Incident security breach involving the BIG-IP product
- Market impact shares fell from $290.41 on October 27, 2025 to $258.76 on October 28, 2025 a two-day decline of 10.9 percent
The case is Smith v. F5, Inc., et al., No. 25-cv-02619 and is pending in the United States District Court for the Western District of Washington. The complaint alleges F5 and certain executives failed to disclose material information during the class period.
F5’s October 27, 2025 fourth quarter fiscal year 2025 results included below-market growth expectations for fiscal 2026 and forecasts of reduced sales and renewals, longer sales cycles, cancelled projections, and increased expenses in part linked to a security breach affecting BIG-IP.
The reported share decline occurred between a closing price of $290.41 on October 27, 2025 and $258.76 on October 28, 2025. The lawsuit covers purchases made between October 28, 2024 and October 27, 2025 and seeks recovery for alleged economic losses.
WHY IT MATTERS
The February 17, 2026 deadline sets a timetable for investors to seek lead plaintiff status and to participate in the litigation process. The case addresses whether the breach and the guidance change caused investor losses and the extent of potential recovery.
