Viavi Solutions delivered a solid QQ3 2025 performance with revenue of $284.8 million, marking a 15.8% year-over-year increase and a 5.2% sequential uptick. GAAP and non-GAAP results diverge in the call notes, with GAAP diluted EPS of $0.088 and a call-reported non-GAAP EPS of $0.15, underscoring a favorable mix and operating leverage that exceeded guidance. The quarter showcased broad strength across Viavi’s three segments (Network Enablement NSE, Service Enablement SE, and Optical Security and Performance Products OSP) and highlighted the company’s strategic growth engines: data-center driven fiber lab and production (NSE NE), aerospace/defense growth via Inertial Labs, and continuing momentum in anti-counterfeiting and 3D sensing within OSP. Management signaled a constructive, albeit cautious, near-term outlook due to tariffs, with Q4 revenue guided to roughly flat versus Q3 and a low-single-digit margin impact from tariff-related costs.
