Seagate Technology Holdings plc (STX) Income Statement

The sequential acceleration from 21.3% in 2026Q1 to 48.5% in 2026Q4 indicates a robust demand cycle, likely driven by hyperscale cloud capex and AI-related storage needs. The sustained double-digit growth across all quarters suggests a durable upcycle, though investors should monitor for potential normalization as the cycle matures.

The dramatic margin expansion suggests strong pricing power and operational leverage from higher factory utilization, likely aided by the ramp of HAMR technology and a richer product mix. However, the sustainability of these margins depends on continued demand and the ability to offset price erosion per terabyte, which remains a structural headwind.

The operating margin expanded from 8.6% to 42.5% over the same period, far outpacing gross margin gains, which suggests that SG&A and R&D costs are scaling well below revenue growth. This implies that the company is benefiting from fixed-cost absorption and disciplined expense control, though the recent EPS miss relative to estimates warrants monitoring for potential cost pressures.

The stability of SG&A despite a doubling of revenue highlights management's expense discipline, contributing to the operating leverage observed. R&D spending increased modestly from $164M to $188M, reflecting continued investment in HAMR and next-gen technologies, which is essential for maintaining competitive advantage but may pressure margins if revenue growth slows.
