On October 15, 2025, F5 disclosed a "long-term, persistent" breach to its systems, during which the Company’s BIG-IP product development and engineering management platforms were compromised, including the BIG-IP source code.
On this news, F5’s stock price fell $47.82 per share, or 13.93%, over the following two trading sessions, to close at $295.35 per share on October 16, 2025.
Then, on October 27, 2025, F5 announced its further quarter fiscal year 2025 results, providing significantly below-market growth expectations for fiscal year 2026 due in significant part to the impact of the security breach, which caused the Company to announce expected reductions to sales and renewals, elongated sales cycles, terminated projections, and increased expenses attributed to ongoing remediation efforts.
On this news, F5’s stock price fell another $30.76 per share, or 10.31%, over the following two trading sessions, to close at $258.76 per share on October 28, 2025.
