VIAVI Solutions (VIAV) Stock Forecast: What Could Drive It in 2026
Short answer
What is actually driving VIAVI Solutions (VIAV) right now is AI and data-center testing demand: The clearest driver is spending on AI infrastructure and hyperscale data centers, which need high-speed ethernet and optical test tools. Revenue (TTM) is ~$1.05B. If that keeps playing out, the setup is favourable; the risk to it is vIAVI's revenue is cyclical and tied to network operator, hyperscaler, and government capital spending, any of which can pause. No one can predict where VIAV trades, and Walnut does not publish targets, so treat this as a scenario, not a price target or prediction.
What could drive VIAVI Solutions (VIAV) higher?
1. AI and data-center testing demand
The clearest driver is spending on AI infrastructure and hyperscale data centers, which need high-speed ethernet and optical test tools. VIAVI's NSE segment grew about 54 percent year over year in fiscal Q3 2026, and the acquired Spirent high-speed ethernet assets add roughly $200 million in annualized revenue aimed squarely at this market.
2. Aerospace, defense, and PNT
Resilient position, navigation, and timing (PNT) plus aerospace and defense end markets have exceeded the company's own expectations. The Inertial Labs acquisition broadened VIAVI's exposure to navigation and sensing systems used in military and industrial applications, diversifying it away from a reliance on carrier network spending.
3. Margin expansion and cost discipline
Non-GAAP operating margin expanded to about 21 percent in fiscal Q3 2026, up roughly 430 basis points year over year. A fiscal 2026 restructuring plan targets around $30 million in annual operating cost reductions, and management has prioritized paying down acquisition debt, with Fitch and S&P adjusting their credit ratings accordingly.
4. Optical security recovery
The OSP segment, which supplies anti-counterfeiting pigments for banknotes and optical filters for consumer electronics, grew about 11 percent year over year in fiscal Q3 2026. It is a lumpier, program-driven business but provides higher-margin ballast to the faster-moving network test segment.
What could weigh on VIAV?
VIAVI's revenue is cyclical and tied to network operator, hyperscaler, and government capital spending, any of which can pause. The stock has re-rated sharply, so a forward P/E in the low 40s (as of July 2026) leaves little room for a demand slowdown. The Spirent and Inertial Labs deals added debt, funded partly by a term loan and convertible notes, so integration missteps or higher rates would pressure the balance sheet even after recent prepayments. GAAP profitability has been negative on a trailing basis, and the OSP segment's program-based orders can swing quarter to quarter.
