Viavi's AI-Driven Data Center Demand Fuels Record Q4, But Valuation Stirs Caution

Record Q4 revenue and strong guidance Viavi reported record Q4 revenue of $443.1 million, up 52.5% year-over-year, with EPS of $0.34 beating guidance. The Network and Service Enablement segment surged 69.2% on data center and defense demand. Management guided Q1 fiscal 2027 revenue to $450–460 million and sees a $500 million quarterly milestone sooner than planned. This strong execution and outlook push the stock up.
This is the latest earnings report showing accelerating growth and raised guidance, a key positive driver for the stock.
S&P MidCap 400 inclusion boosts institutional demand Viavi was added to the S&P MidCap 400 index, effective June 22, which forces index-tracking funds to buy the stock. Shares jumped 11.6% on the news. This inclusion increases Viavi's visibility and brings in steady institutional demand, supporting a higher stock price.
Index inclusion is a major capital event that directly increases demand for shares and was a significant price catalyst.
New product launches strengthen technology portfolio Viavi launched the µPNT GDO-1000, an ultra-compact precision timing module for defense, data centers, and aerospace. It also earned PCI-SIG Gold Suite acceptance for its PCIe 6.0 testing platform. These innovations position Viavi to capture growth in AI and high-performance computing, driving future revenue and investor optimism.
New products expand Viavi's addressable market and reinforce its technology leadership, supporting long-term growth.
Valuation concerns after massive run-up Despite strong earnings, Viavi's stock has pulled back 23.8% over the past 90 days, closing at $38.90. It trades at 7x price-to-sales, above the industry average of 2.3x, raising valuation worries. Some analysts see it 40% undervalued, but the high multiple creates a tug-of-war between growth potential and price risk.
This highlights the key counterweight: while fundamentals are strong, the stock's high valuation and recent pullback create uncertainty.
