Research and Development Expense

Apple Inc. · 2025-10-31 · Importance 54 · Surprise 40

R&D expense for fiscal 2025 was $34,550 million, an increase from $31,370 million in 2024; management attributes the growth primarily to increases in headcount‑related expenses and infrastructure‑related costs. The filing identifies personnel and infrastructure as the principal drivers of higher R&D spend in FY2025. This level of investment represents a material operating expense line and is cited as a contributor to overall operating expense growth. Management’s disclosure signals sustained elevated R&D cost base going forward absent offsetting actions.
