How it Works

  • A lawsuit is initiated by one or more investors, called the “lead plaintiffs,” on behalf of a larger group of investors, or the “class”.
  • The “class period” is defined as the specific timeframe during which the alleged fraudulent activity took place. Only those who bought or sold the security during this period are eligible to participate.
  • A lead plaintiff is appointed to represent the class. Under the Private Securities Litigation Reform Act (PSLRA), the court will typically appoint the investor with the largest financial interest in the outcome of the case.
  • The case is litigated, which may include a lengthy discovery phase for gathering evidence.
  • The case can be settled or go to trial. Most class actions are resolved through settlements, which can include cash or stock paid into a common fund for the class. The lead plaintiff and class counsel approve any settlement before it is finalized.

 

Common Types of Misconduct

  • Securities fraud class actions can arise from various types of misconduct by a company, its officers, or others involved in the sale of its securities, including:
  • Making false or misleading statements in SEC filings, prospectuses, or earnings announcements.  
  • Overstating a company’s revenues or profits through fraudulent or “creative” accounting.  
  • Failing to disclose material information that would significantly alter an investor’s view.  
  • Engaging in market manipulation to artificially inflate or deflate a security’s price.

What Plaintiffs Must Prove

To succeed in a federal securities fraud class action, plaintiffs must prove several elements:

  • Material misstatement or omission: The company made a false or misleading statement, or failed to disclose a material fact.  
  • Scienter: The defendant acted with an intent to deceive, manipulate, or defraud. 
  • Reliance: The plaintiff relied on the misstatement or omission when buying or selling the security. For publicly traded securities, this can be proven through the “fraud-on-the-market” theory, which presumes the market price reflects all public, material information.
  • Economic loss: The plaintiff suffered a financial loss. 
  • Loss causation: The company’s misstatement or omission directly caused the plaintiff’s loss, often demonstrated by a stock price drop after the truth is revealed in a “corrective disclosure”

 

Benefits for Investors

  • Participating in a class action allows investors to pool their resources, which offers leverage they would not have in an individual lawsuit against a large corporation.
  • The collective approach also makes it more efficient and cost-effective to pursue legal action, especially for smaller investors.

 

How to Get Involved

  • If you bought a security during the alleged class period and suffered a loss, you are generally automatically included in the class. You don’t have to take any action unless you want to file a claim for recovery later.
  • You may be notified of a class action by mail if you are an eligible class member.
  • You may be able to become a lead plaintiff by applying within 60 days of the first lawsuit being announced.
  • If you believe you may have a claim, you can contact a securities class action law firm for guidance. 

Allegations in the F5 Class Action Lawsuit

F5 is a global multi-cloud application security and delivery company which enables customers to deploy, secure, and operate applications on-premises or via public cloud.

The F5 class action lawsuit alleges that throughout the Class Period, defendants created the false impression that they possessed reliable information pertaining to F5’s projected revenue outlook and anticipated growth while also minimizing risk from seasonality and macroeconomic fluctuations.

The complaint alleges that in truth, F5’s optimistic claims, touting its purported best-in-industry security and overall emphasis and confidence in F5’s ability to meet and capitalize on the growing security needs for its clientele fell short of reality; F5 was, at the time, the subject of a significant security incident, placing its clientele’s security and F5’s future prospects at significant risk.

”The F5 class action lawsuit further alleges that on October 15, 2025, F5 disclosed that “[i]n August 2025, we learned a highly sophisticated nation-state threat actor maintained long-term, persistent access to, and downloaded files from, certain F5 systems.  These systems included our BIG-IP product development environment and engineering knowledge management platforms.”  On this news, the price of F5 stock fell nearly 14% over two trading days, according to the complaint.

Then, on October 27, 2025, the F5 class action lawsuit further alleges that F5 published its fourth quarter fiscal year 2025 results, providing significantly below-market growth expectations for fiscal 2026 due in significant part to the security breach as F5 announced expected reductions to sales and renewals, elongated sales cycles, terminated projections, and increased expenses attributed to ongoing remediation efforts.  Defendants also allegedly disclosed that BIG-IP, the product that was the subject of the security breach, is F5’s highest revenue product. 

On this news, the price of F5 stock fell nearly 11% over two trading days, according to the complaint.


Options Available to Shareholders

  • Do Nothing (Remain a Class Member): This is the most common option. If you take no action, you automatically remain a member of the class.
  • Exclude Yourself (Opt-Out)You have the absolute right to exclude yourself from the class action. This is often referred to as “opting out.”
  • How to Exclude Yourself (Opt-Out):  The process for opting out is not available immediately, but only when the class has been formally certified and a settlement or trial is imminent.
    • Wait for the Class Notice: If a settlement is reached, the court will approve a Notice of Proposed Settlement that is mailed to all known class members.
    • Review the Notice: This document will contain specific, formal instructions on how to exclude yourself from the settlement.
    • Submit a Written Request: You must draft and mail a letter stating clearly that you wish to be excluded from the class action, and include all identifying information (name, address, shares sold, etc.).

 

  • Meet the Deadline: Your exclusion request must be postmarked by the deadline in the Notice.
