Viavi Solutions Inc. has transformed from telecom-focused to a diversified growth story, with AI data centers and aerospace/defense now driving two-thirds of NSE revenue. Fiscal 2026 revenue surged 40% to $1.52B, and non-GAAP operating margin expanded to 20.6%; Q4 revenue grew 52.5% YoY, signaling operational momentum. Acquisitions of Spirent and Inertial Labs fueled growth and diversification, while a $575M equity raise improved the balance sheet but diluted shareholders.
