Viavi Solutions Inc. (VIAV) shares skyrocketed 13.11% in the after-hours trading session on Thursday following the company's better-than-expected fiscal second-quarter 2025 results and an upbeat outlook for the third quarter.

The network test, monitoring and assurance solutions provider reported adjusted earnings per share of $0.13 for the quarter ended December 28, 2024, surpassing the consensus estimate of $0.10. Revenue of $270.8 million also topped analysts' expectations of $259.99 million, driven by a recovery in demand for its Network Enablement products.

Viavi's Network Enablement segment, which includes products for fiber optic network deployment and maintenance, saw a 15.1% year-over-year increase in revenue to $179 million. The company attributed this growth to the ongoing expansion of 5G networks and the increasing demand for high-speed internet connectivity.

Furthermore, Viavi provided an optimistic outlook for the third quarter of fiscal 2025, projecting revenue between $276 million and $288 million and non-GAAP earnings per share in the range of $0.10 to $0.13. The company's CEO, Oleg Khaykin, stated that the recovery in traditional service provider markets, coupled with growth opportunities in new markets like data centers and aerospace and defense applications, positions Viavi favorably for a long-term growth cycle.
