About the Lawsuit

F5 and certain of its executives are charged with failing to disclose material information during the Class Period, violating federal securities laws.

On October 27, 2025, the Company announced its fourth quarter fiscal year 2025 results, disclosing significantly below-market growth expectations for fiscal 2026 including expected reductions to sales and renewals, elongated sales cycles, terminated projections, and increased expenses due in significant part to a security breach involving BIG-IP, the Company’s highest revenue product.

On this news, the price of F5’s shares fell from a closing market price of $290.41 per share on October 27, 2025 to $258.76 per share on October 28, 2025, a decline of an additional 10.9% in the span of two days.

The case is Smith v. F5, Inc., et al., No. 25-cv-02619.
