Western Digital's Revenue Surges 45% on AI Storage Demand
Western Digital reported third-quarter fiscal 2026 revenue of $3.34 billion, up 45% year over year, as hyperscalers and enterprises expand storage infrastructure for AI workloads. The company beat analyst expectations and its own guidance, signaling sustained momentum in a market where data generation from AI training, inference, and deployment continues to accelerate.
Earnings per share reached $2.72 on a non-GAAP basis, nearly double the prior-year quarter and ahead of the $2.41 consensus estimate. Operating margin expanded to 38.6%, up 1,260 basis points year over year, driven by higher-capacity drive sales and disciplined cost management.
Where the Growth Is Coming From
Cloud infrastructure accounts for 89% of revenue and grew 48% year over year to $3 billion. This segment benefits directly from data center expansion tied to AI deployments. Client and consumer segments also posted solid gains-31% and 24% year-over-year growth respectively-supported by improved pricing and higher-capacity products.
Western Digital shipped 222 exabytes in the quarter, up 34% year over year. The company shipped 4.1 million next-generation ePMR drives with capacities up to 32TB, demonstrating rapid scaling of new storage technology to meet demand.
Margin Expansion and Cash Generation
Gross margin reached 50.5%, beating guidance of 47-48% and reflecting a richer product mix of higher-capacity drives. Operating expenses improved 23% year over year despite increased R&D spending on HAMR (heat-assisted magnetic recording) qualifications.
The company generated $978 million in free cash flow, up 124% year over year. Western Digital returned $2.2 billion to shareholders since launching its capital return program in the fourth quarter of fiscal 2025, including $752 million in share repurchases and $43 million in dividends during the quarter.
The board declared a quarterly dividend of 15 cents per share, payable June 17, signaling confidence in sustained earnings power and cash generation.
Forward Guidance Points to Continued Strength
For fiscal Q4 2026, Western Digital expects revenue of $3.65 billion, implying roughly 40% year-over-year growth at the midpoint. Non-GAAP earnings are projected at $3.25 per share, with gross margin expected between 51-52%.
The stock gained 5.3% on the earnings announcement, closing at $434.52. Over the past year, shares have risen 888.7%, outpacing the broader computer-storage devices industry gain of 460.1%.
