Viavi Solutions: Strong Profit Growth Makes Valuation More Attractive

Viavi Solutions is rated Buy with a $37 price target following robust revenue and profit growth driven by AI data-center, optical-testing, and aerospace-and-defense demand. Growth in 1.6T and co-packaged optics (CPO) technologies is expected to accelerate, while margin expansion and resilient defense revenue support further upside despite the stock's higher valuation.

Analysis

VIAV's setup is less about data-center capex volume than the timing and complexity of network transitions. 1.6T and co-packaged optics raise test intensity per deployed link, which can support revenue growth ahead of broad equipment shipments and create favorable mix leverage in service/software-adjacent test workflows. The key competitive comparison is KEYS: VIAV can outperform if hyperscaler optical validation spending accelerates while general-purpose electronic test demand remains softer, but its narrower product breadth also makes customer concentration and qualification delays more consequential.

The near-term catalyst path is hyperscaler 1.6T design wins, optical-module production ramps, and evidence that gross-margin expansion is recurring rather than a favorable quarter of mix. Over 6-18 months, CPO adoption could expand the addressable test market, but it may also shift value toward component vendors such as COHR and LITE if deployment remains module-centric rather than architecture-changing. Aerospace/defense demand provides earnings stability, yet it should not command an AI-style multiple unless management demonstrates sustained operating leverage and backlog conversion.

The contrarian risk is that investors capitalize a multi-year CPO opportunity before meaningful production deployment. A pause in cloud capex, delayed 1.6T qualification, or revenue growth that fails to exceed operating-expense growth would compress a premium valuation quickly; this is particularly relevant because the supplied information does not establish current forward EV/sales, backlog, customer concentration, or the portion of growth attributable to nonrecurring programs. The thesis is falsified by two consecutive quarters of data-center weakness, gross-margin contraction, or guidance implying that AI-related demand is merely offsetting legacy-network declines.

Key Decisions for Investors

• Initiate only a starter long in VIAV on confirmation of next-quarter data-center guidance and gross-margin expansion; target a 10-15% upside over 3-6 months, with a 7-8% stop or exit if management signals delayed 1.6T/CPO production timing.
• Prefer a relative-value expression: long VIAV / short KEYS in equal dollar amounts for 3-6 months if VIAV reports faster communications-test growth and stable margins. This isolates the optical-transition thesis from a broad technology multiple rerating; close if KEYS' communications segment reaccelerates or VIAV misses guide.
• Do not underwrite a standalone CPO-driven rerating until disclosed design-win, backlog, and revenue-conversion data establish material production exposure. Set an alert around earnings for hyperscaler concentration, deferred revenue/order trends, and R&D intensity; absent those disclosures, treat any sharp post-results rally as valuation risk rather than a chase entry.
• For defense exposure, avoid extrapolating resilience into a primary upside driver. Reassess the long if aerospace/defense growth decelerates while optical-test growth fails to accelerate, since the combined result would remove both the earnings floor and the growth premium.
