What changed since last quarter
Revenue was $2.0 billion in Q2 FY2026, up 10.7% against Q1 FY2026 and 25.6% against Q2 FY2025. Management attributes year-over-year product-revenue growth in Q2 FY2026 to higher unit shipments, higher average selling prices and recent pricing actions; it also cites demand for higher-performing models, AI-infrastructure deployments, technology upgrades, upsell activity and new use cases.
Operating income was $689.3 million in Q2 FY2026, up from $580.0 million in Q1 FY2026 and $458.0 million in Q2 FY2025. Operating margin was 33.7% in Q2 FY2026, increasing by 2.3 percentage points against Q1 FY2026 and 5.6 percentage points against Q2 FY2025. Management attributes the year-over-year margin increase to revenue growth outpacing operating-expense growth, partly offset by lower gross margin. Gross margin was 80.2% in Q2 FY2026, down −0.4 percentage points against Q2 FY2025, which management attributes to a mix shift toward lower-margin product revenue.
