Lumentum Holdings Inc. Earnings Summary — Q3 2026

• Revenue surged 90.1% YoY to $808.4 million, reflecting a massive turnaround in optical demand.
• GAAP Operating Income reached $174.5 million, a significant recovery from an operating loss of $37.7 million in the prior year quarter.
• The surge is primarily driven by AI-driven data center demand and a recovery from the telecom inventory 'digestion' phase.
• Net income growth was exponential, rising from $4.2 million in the previous quarter to $144.2 million.
• Cost of revenue grew at a slower pace (52.3% YoY) than total revenue (90.1%), leading to significant margin expansion.
• Diluted shares outstanding increased to 96 million in Q3 2026, suggesting potential conversion of dilutive securities or high equity-based compensation.

Management is focused on the move to high-speed transceivers and VCSELs for 3D sensing, targeting AI-driven optical interconnects as the primary growth frontier.

Improving

A clear transition from GAAP losses and inventory headwinds to robust profitability and accelerated revenue growth driven by AI data center needs.

The company likely continues to benefit from the infrastructure build-out for AI. The stabilization of the telecom sector and successful manufacturing consolidation are expected to support higher margins through FY2026.
