Viavi Solutions reported a strong fiscal second quarter of 2026, with revenue reaching $369.3 million, up 23.5% sequentially and 36.4% year-over-year, beating the high end of guidance. EPS of $0.22 significantly exceeded guidance (up $0.07 sequentially), driven by a 360 basis point expansion in operating margin to 19.3%. Performance was led by the Network Service Enablement (NSE) segment, which grew 45.8% year-over-year to $291.5 million, fueled by robust demand from the data center ecosystem and aerospace & defense markets, offsetting weaker service provider demand. Looking ahead, management raised guidance for the third quarter, projecting revenue of $386 million to $400 million—representing sequential growth in a typically seasonally flat period—driven by continued AI data center build-outs and A&D strength, while also announcing a restructuring plan to reduce the workforce by 5% to capture $30 million in annual savings.

Viavi is undergoing a significant business mix transformation, reducing reliance on traditional service providers (now ~40% of NSE) in favor of high-growth sectors like data centers (~45% of NSE) and aerospace & defense (~15%). This shift is driving the 'counter-cyclical' growth guidance, where strength in AI infrastructure and defense offsets weakness in telco. Management emphasized that data center demand is not just lab-based but expanding into production and field instruments, providing a broader revenue base.
A major strategic development is the direct adoption of Viavi's fiber field instruments by hyperscalers. Historically, these tools were sold to telecom operators; now, data center operators are buying them to monitor and optimize fiber performance for AI workloads. This creates a new, high-volume customer base and validates the critical nature of Viavi's technology in the AI supply chain, moving beyond just manufacturing test into live network monitoring.
The company is aggressively reallocating capital and resources to align with this new growth profile. The announcement of a 5% workforce reduction, targeting $30 million in annual savings (including $16 million in Spirent synergies), indicates a focus on operational efficiency. Management explicitly stated that cost cuts are coming from 'slower or stagnant product segments' to free up resources for investment in data center and A&D growth areas.
Viavi is strengthening its balance sheet through proactive debt management. The company exchanged $100 million in convertible notes and prepaid $100 million of its term loan, demonstrating financial discipline. However, the upcoming $75 million earn-out payment for Inertia Labs highlights the success of that acquisition, reinforcing the M&A strategy as a viable growth engine, particularly in resilient PNT (Positioning, Navigation, and Timing) for autonomous systems.
The announcement of a restructuring plan impacting 5% of the global workforce suggests that despite the revenue beat, the company faces structural cost inefficiencies or needs to realign its cost base rapidly to maintain margins. While management frames this as reinvestment, the $32 million in charges and the nature of workforce reductions often signal underlying operational friction or a need to right-size following acquisitions.
Revenue from the acquired Spirent product lines was $43 million, slightly below the expectation of $45 million to $55 million, attributed to timing issues and government shutdowns. While management expects a rebound in Q3, the miss highlights integration risks and the volatility of government-dependent revenues, which can be lumpy and sensitive to administrative delays.
The company faces a significant cash outflow in Q3, with an expected $75 million earn-out payment for Inertia Labs due to strong performance. While this indicates a successful acquisition, it will pressure free cash flow in the short term. Additionally, the exchange of convertible notes for 7.9 million shares increases the share count, contributing to dilution for existing shareholders.
Management noted that 'demand for wireless infrastructure test continues to be weak but stable.' This indicates that a portion of the legacy business remains a drag, and the company is entirely dependent on the data center and A&D cycles to sustain growth. If the AI build-out slows or defense spending moderates, the company lacks a strong third leg of growth in the near term.
Overall: Management exhibited a high level of confidence and enthusiasm, particularly regarding the company's successful pivot toward high-growth markets like AI data centers and aerospace & defense. The tone was pragmatic yet optimistic about operational efficiency, as evidenced by the immediate restructuring announcement following a strong earnings beat. There was a notable shift from defensive language to aggressive growth commentary during the Q&A, specifically when discussing the 'truly amazing' turnaround in field instruments.
Confidence: HIGH - Management provided specific metrics to support their bullish outlook, such as the precise mix shift in revenue (45% data center) and detailed visibility into demand drivers. They comfortably addressed questions about sustainability and restructuring without hesitation, indicating strong control over the business narrative.

Hedging & Uncertainty: Management used minimal hedging regarding the primary growth drivers, speaking with certainty about the data center and A&D momentum. Phrases like 'expect the data center ecosystem revenue momentum to continue' and 'expect this trend to continue' show high conviction. However, hedging was present regarding the Spirent integration and short-term government orders, with phrases like 'slightly below our expectation' and 'timing of certain opportunities.' The use of 'counter-cyclically up' serves as a strong hedge against seasonal norms, preparing investors for a deviation from historical patterns.

Viavi Solutions is executing a successful strategic pivot, transforming from a telecom-dependent vendor to a key enabler of the AI data center ecosystem and modern aerospace & defense. The Q2 results demonstrate the power of this shift, with massive Y/Y growth and margin expansion driven by NSE. The guidance for sequential growth in Q3, defying typical seasonality, underscores the strength of current demand drivers. While the restructuring and Spirent integration present near-term noise, the long-term trajectory is compelling. The company is effectively leveraging M&A (Inertia, Spirent) and organic R&D to capture share in high-growth markets like hyperscaler fiber monitoring and resilient PNT. The balance sheet remains healthy, supporting this transition. We view the current valuation as attractive given the accelerating growth profile and margin leverage.
Management confirmed that AI data center build-outs are driving massive demand for test and measurement equipment across lab, production, and field instruments. Hyperscalers are directly investing in fiber monitoring tools to ensure low latency, a new and durable trend.
Demand for 'Resilient PNT' (Positioning, Navigation, and Timing) is surging, driven by the need for GPS-denied navigation in drones and autonomous systems. This sector is providing a stable, high-growth counterbalance to the telecom market.
The traditional service provider market remains 'weak but stable.' While there is opportunistic demand related to DAA architecture, the sector is no longer the primary growth engine, creating a dichotomy where Viavi grows despite telco headwinds.
