- Security Incident Disclosure: On October 15, 2025, F5 revealed that its systems were compromised by a nation-state threat actor, resulting in the exfiltration of portions of the BIG-IP source code and undisclosed vulnerabilities, significantly impacting the company's reputation and client trust.
- Stock Price Plunge: Following the security breach announcement, F5's stock dropped by $35.40, or 10.7%, closing at $295.35 on October 16, 2025, causing substantial losses for investors.
- Dismal Financial Outlook: In its Q4 fiscal 2025 results released on October 27, 2025, F5 projected reduced sales and renewals due to the security breach, leading to a further stock decline of $22.83, or 7.8%, to $267.58, which further eroded investor confidence.
- Class Action Initiated: Investors have filed a class action lawsuit against F5 for failing to disclose the security incident, alleging that misleading statements throughout the class period may have led to greater investor losses.
