F5 Lawsuit Submission Form

According to the complaint, defendants provided overwhelmingly positive statements to investors while, at the same time, disseminating materially false and misleading statements and/or concealing material adverse facts concerning the true state of F5’s security capabilities; notably, that it was not truly equipped to safely secure data for its clients as F5 itself was, for all relevant times, experiencing a significant security breach (the “Security Breach”) of some of its key offerings and, further, that the revelation of this breach would significantly impact F5’s potential to capitalize on the security market.

On October 27, 2025, F5 announced their fourth quarter fiscal year 2025 results after the market closed, providing significantly below-market growth expectations for fiscal 2026 due in significant part to the Security Breach as the Company announced expected reductions to sales and renewals, elongated sales cycles, terminated projections, and increased expenses attributed to ongoing remediation efforts. Pertinently, defendants also disclosed that BIG-IP, the product that was the subject of the Security Breach, is the company’s highest revenue product, elevating the scope of the impact from the original disclosure as F5 does not otherwise provide revenue contributions by product line.

Following this news, the price of F5’s common stock declined dramatically. From a closing market price of $290.41 per share on October 27, 2025, F5’s stock price fell to $258.76 per share on October 28, 2025, a decline of an additional 10.9% in the span of two days.
