VIAV Stock: AI Data Center Boom Drives Q4 Beat

Aug 27, 2026
Bobby Quant Team

💡 Key Takeaway

VIAV's strong Q4 results and AI-driven growth make it a compelling buy, but investors should watch integration risks from the Spirent acquisition.

VIAV's Q4 Earnings Beat Expectations

Viavi Solutions (VIAV) reported fiscal Q4 results that beat analyst expectations, with revenue growing 52.5% year-over-year and EPS surging 161.5%. The company's strong performance was driven by robust demand for its network test and measurement solutions, particularly from AI data center customers.

Management highlighted that AI data center exposure now accounts for roughly half of NSE (Network and Service Enablement) revenues, and they expect this segment to continue growing robustly. The company also completed the acquisition of Spirent Communications, which expands its addressable market and product portfolio.

Looking ahead, VIAV provided upbeat Q1 guidance, projecting sequential revenue and EPS increases. Management also raised their expectations for reaching $500 million in quarterly revenue to calendar 2027, earlier than the previous fiscal 2028 target.

The stock has already rallied significantly, gaining 244.1% over the past year, and is currently rated a Zacks Rank #1 (Strong Buy).

Why VIAV's Results Matter for Investors

VIAV's strong Q4 results underscore the accelerating demand for network testing and assurance solutions in the AI era. As data centers expand to support AI workloads, they require more sophisticated testing to ensure performance and reliability, which directly benefits VIAV.

The Spirent acquisition is a strategic move that strengthens VIAV's position in the market, adding complementary products and expanding its customer base. This could drive further revenue growth and margin expansion over time.

However, investors should consider the integration risks associated with the acquisition. Merging two companies can be complex, and there's always the potential for operational hiccups or culture clashes that could impact performance.

Despite the strong momentum, VIAV's stock has already appreciated significantly, which may limit upside potential in the near term. Valuation is a key consideration, as the market may have already priced in much of the good news.

Overall, the company's fundamentals are strong, and the AI tailwind is likely to persist, but investors should weigh the growth prospects against the current valuation and integration risks.

What This Means for Me

If you hold VIAV, the positive earnings and guidance are likely to boost your portfolio's value, but consider taking some profits given the stock's recent run. If you don't hold VIAV, you might look at competitors like KN or AIRG, but they may not benefit as directly from AI data center trends. Diversifying across the sector could mitigate risks.
