DiCello Levitt Named Lead Counsel in F5 Securities Class Action

Mar 13, 2026

Lawsuit Alleges F5, A Major Cybersecurity and Technology Company, Misled Investors About Cybersecurity Risks and A Data Breach

On March 13, 2026, U.S. District Judge Kymberly K. Evanson of the United States District Court for the Western District of Washington named DiCello Levitt as Lead Counsel in Smith v. F5, Inc., et al., Case No. 2:25‑cv‑02619‑KKE, a federal securities class action brought on behalf of investors who purchased F5 securities between October 28, 2024, and October 27, 2025.

F5, Inc. is a publicly traded technology company headquartered in Seattle that provides cybersecurity, application delivery, and cloud software solutions to customers worldwide.

The F5 class action alleges that defendants misled investors regarding the true state of F5’s security capabilities and concealed that the Company was not truly equipped to safely secure data for its clients. According to the complaint, F5 itself was experiencing a years-long security breach where a nation-state threat actor accessed F5’s internal systems and stole BIG-IP source code and information about “undisclosed vulnerabilities,” exposing over 260,000 F5 BIG-IP systems globally to potential exploitation.

DiCello Levitt’s team on the matter includes Brian O’Mara, Roxana Pierce, Henry Rosen, Tricia McCormick, and Hani Farah.
