    Data Center Ecosystem Revenue Momentum

    CY26 and beyond
    CurrentStrong and growing demand, exit velocity in high 40s % of NSE revenue
    TargetContinued strong growth, potentially reaching 50% of NSE revenue

    Why it matters

    The data center ecosystem is a primary growth driver for Viavi, crucial for overall revenue and margin expansion.

    Given strong and growing customer demand, we expect the data center ecosystem revenue momentum to continue through the calendar 2026.

    Q&A highlights

    5

    Could you provide more detail on the specific drivers within the data center momentum, distinguishing between lab, production, and field segments, and discuss customer visibility?

    Oleg detailed that lab-side demand comes from optical transport and PCIe express test products for AI chip development. Production-side momentum is driven by co-packaged optics and integrated packaged optic solutions, requiring spectral performance measurement. Field instrumentation is seeing strong demand for fiber monitoring solutions as data centers come online, now accounting for 40-50% of field instrument revenue.

    I mean, it's now approaching cost to, let's say, 40%, 45% -- pretty soon probably maybe 50% of the field instruments is actually driven by the data center.

    Detailed Narrative

    01

    Data Center Ecosystem Momentum

    Viavi is experiencing strong demand across all data center segments, including scale up, scale out, and scale across. This is driven by industry investment in higher communication speeds and chip-to-chip interconnect technologies. The company's optical transport, silicon photonics, communication protocol, and high-speed Ethernet test equipment are critical for AI chip development, co-packaged optics production, and fiber monitoring in new data centers. Field instrument demand from data centers is now approaching 40-50% of the total.

    02

    Aerospace and Defense Growth

    The Aerospace and Defense business continues to show strong quarter-on-quarter growth, primarily driven by demand for positioning, navigation, and timing products. This momentum is expected to continue through the calendar year. The Inertial Labs acquisition has significantly exceeded forecasts, with strong demand for its sensors and inertial navigation systems in autonomous vehicles (air, land, sea, undersea), including drones. The company is expanding its engagement with U.S. Tier 1 players after implementing ITAR and secure access systems.

    03

    Spirent Integration and Synergies

    The recently acquired Spirent high-speed Ethernet product lines performed in line with expectations, providing access to a large installed base of enterprise customers. Viavi is leveraging Spirent's established reputation and application-hardened software, while upgrading its hardware performance. The first truly integrated product between Viavi and Spirent is expected to be 3.2 terabits, building on their combined 800-gig position and expanding cross-selling opportunities for a broader product mix.

    04

    Operating Leverage and Profitability

    Viavi is demonstrating significant operating leverage, with the NSE business nearing 20% operating profit and OSP maintaining high margins. For every incremental dollar in NSE, approximately 40-45% falls through to the bottom line. The company benefits from a low effective tax rate of about 12% due to the utilization of NOLs, particularly for profits generated in North America where IP and R&D are located, further enhancing overall profitability.

    05

    Wireless Business and Future Opportunities

    The service provider business, including wireless and service enablement, follows seasonal patterns, being weaker in March and September quarters. While current wireless business demand is weak but stable, it is not expected to recover in the near term. However, Viavi is focusing on next-generation wireless technologies such as 6G, NTN (Non-Terrestrial Networks), AI RAN (AI-driven Radio Access Networks), and ground-to-satellite communication, anticipating future market rebound.

    06

    Supply Chain Management and Component Access

    Viavi proactively manages its supply chain by anticipating potential component shortages and strategically building inventory. The company's position at the forefront of test and measurement allows it to secure early access to alpha or beta silicon, ensuring product development aligns with market releases. While component shortages exist (e.g., memory), Viavi's volume requirements and willingness to pay higher ASPs ensure availability, prioritizing product functionality and timely delivery over cost for bleeding-edge products.

    07

    Test and Measurement as a Bottleneck in Advanced Packaging

    The increasing complexity of advanced packaging, including co-packaged optics, near-package optics, and heterogeneous integration, has elevated test and measurement to a strategic asset and a critical bottleneck. Viavi's technologies are being integrated into the entire value chain, from individual optical components to wafer-level packaging and major test platforms. This represents a significant new business area, as the need for rigorous testing at multiple insertion points is crucial for yield and reliability in these complex, integrated systems.
