Western Digital revenue jumped in the fiscal first quarter as cloud and enterprise customers added storage capacity for expanding data workloads. The company reported $4.38 billion in revenue for the quarter ended October 2, 2026, up 55% from $2.82 billion a year earlier and 17% from the prior quarter.
The October 22 release also showed sharply higher margins, cash generation and adjusted earnings. Management tied the improvement to robust customer demand, better pricing and disciplined execution as AI-driven data growth increases storage requirements.
Western Digital revenue and margins accelerate
Western Digital’s official results showed GAAP gross margin of 57.8%, up from 43.5% a year earlier. GAAP operating income more than doubled to $2.05 billion, producing an operating margin of 46.7% compared with 28.1% in fiscal Q1 2026.
Diluted GAAP earnings rose to $4.63 a share from $3.07. On the company’s adjusted basis, diluted EPS reached $4.64, up 161% year over year, while adjusted operating margin expanded to 49.1%.
Cash flow strengthened alongside earnings. Operating cash flow increased to $1.60 billion from $672 million, and the company’s non-GAAP free cash flow measure rose to $1.38 billion from $599 million.

The chart highlights the sequential and annual acceleration without implying a stock-price forecast. The quarter-to-quarter comparison matters because the prior period included a lower revenue base, while the year-over-year gain captures the broader storage-demand recovery.
AI storage demand supports the Q2 outlook
Western Digital forecast fiscal Q2 revenue of $5.1 billion, plus or minus $100 million. At the midpoint, that would represent 66% to 72% year-over-year growth, while adjusted gross margin is expected between 60% and 61% and adjusted diluted EPS at $5.80, plus or minus $0.20.
CEO Irving Tan said the company is broadening its customer base and extending visibility into future demand. CFO Kris Sennesael pointed to robust exabyte growth and improved pricing. Those comments connect the results to the larger AI infrastructure cycle, where model training, inference and data retention all create demand beyond compute chips alone. Fusion Market News’ AI inference explainer provides additional context on how production workloads differ from model training.
The board raised the quarterly cash dividend by 17% to $0.175 a share, payable December 17 to shareholders of record on December 4. Investors should still separate operating momentum from the durability of pricing, customer concentration and capital returns.
The quarter exceeded the company’s previous revenue midpoint of $4.2 billion and adjusted EPS guidance of $4.00. A disciplined review should compare reported revenue, margins, cash flow and guidance together, as outlined in Fusion Market News’ earnings report guide.
Western Digital’s outlook is company guidance, not a guarantee. Demand volatility, customer concentration, supply constraints and pricing changes could cause actual results to differ from management’s current ranges.
