VIAVI Delivers 43% Revenue Growth with Strong Margins and Upbeat Outlook — Data Center and Defense Markets Lead Surge
Record Revenue and Margin Expansion Signal Healthy Core Business
VIAVI Solutions (NASDAQ: VIAV) has posted one of its strongest quarters yet, announcing third quarter fiscal 2026 results that far surpassed expectations. The company's net revenue climbed to $406.8 million—a 42.8% year-over-year jump—fueled by exceptional growth in the data center and aerospace and defense markets. The uplifts in both GAAP and non-GAAP operating margins reflect not just improved sales, but greater operational efficiency.
"VIAVI's financial performance for the third quarter has exceeded our expectations, driven by strong growth in the data center and aerospace and defense end markets. We expect these end markets to continue to be strong drivers for the foreseeable future," stated Oleg Khaykin, President and CEO of VIAVI.
Non-GAAP Profit Nearly Doubles—Underlying Health Outshines GAAP Dip
While GAAP net income slipped 67% year-over-year, the more closely watched non-GAAP net income soared by 99%, reaching $67.6 million for the quarter. Non-GAAP diluted earnings per share hit $0.27, up 80% over the prior year, underlining the company's strong underlying profitability after adjusting for restructuring and other one-time items.
Operating cash flow turned negative ($26.3 million used), mainly due to a contingent consideration payment. Despite this, VIAVI remains financially solid, holding $508 million in cash and investments as of March 28, 2026, against $1.08 billion in total debt.
Operating Metrics and Segment Growth Highlight Strategic Focus
Both revenue segments showed double-digit expansion. Network and Service Enablement surged 54% year-over-year, while Optical Security and Performance Products grew 11%, confirming strength across multiple end markets. Gross margins lifted in both GAAP (up 110bps to 57.5%) and non-GAAP (up 220bps to 62.2%), while non-GAAP operating margin improved to 21% versus last year's 16.7%.
| Metric | Q3 2026 | Q3 2025 | Year-over-Year Change |
|---|---|---|---|
| Net Revenue (millions) | $406.8 | $284.8 | +42.8% |
| Non-GAAP Operating Margin | 21.0% | 16.7% | +430 bps |

Fourth Quarter Outlook: Further Revenue and EPS Growth Expected
Looking ahead, VIAVI projects its Q4 fiscal 2026 net revenue will be between $427 million and $437 million, with non-GAAP EPS between $0.29 and $0.31. That guidance builds on the positive momentum seen this quarter, especially given the continuing strength in end-markets like data centers and defense.
| Q4 2026 Outlook | Range | Midpoint |
|---|---|---|
| Net Revenue (millions) | $427 – $437 | $432 |
| Non-GAAP EPS | $0.29 – $0.31 | $0.30 |
Key Takeaways: Margin Expansion and Strong Order Trends Support Bullish Case
The quarter's standout features—substantial revenue growth, improving margins, and robust segment performances—suggest that VIAVI is benefiting from secular tailwinds in core technology markets. With management highlighting ongoing momentum in data center and defense spending, and raising short-term guidance, VIAVI's operational improvements appear to have staying power.
As the company continues to sharpen its focus on high-growth sectors, investors and market watchers will want to follow upcoming earnings, segment performance, and any related capital allocation decisions. With operating leverage improving, the key question remains: can VIAVI sustain these gains as competition intensifies and macro risks persist?
