F5 Inc's stock surged 13.15% in after-hours trading on Tuesday, following the release of its quarterly financial results.

The cybersecurity firm reported fiscal first-quarter revenue of $822.5 million, a 7% year-over-year increase that significantly exceeded analyst expectations of $758.1 million. Adjusted earnings per share came in at $4.45, beating the consensus estimate of $3.65. The strong performance was driven by an 11% growth in product revenue, which included a 37% surge in systems revenue.

Furthermore, F5 raised its full-year fiscal 2026 outlook, signaling renewed customer confidence following a systems breach disclosed in October. The company now expects revenue growth between 5% and 6%, up from its previous projection of 0% to 4%. Adjusted earnings per share guidance was also increased to a range of $15.65 to $16.05, compared to the earlier forecast of $14.50 to $15.50. The company attributed the positive momentum to resilient demand for application security and enterprise adoption of hybrid multicloud architectures.
