Record Gross Margin and Cash Flow Mark a Turning Point

Western Digital posted fiscal third-quarter results that underscore a structural shift in the storage industry, driven by insatiable demand from artificial intelligence infrastructure. Revenue hit $3.34 billion, a 45% jump from a year earlier, while GAAP gross margin reached 50.2% and non-GAAP gross margin hit 50.5%. Free cash flow surged to $978 million, giving the company ample room to reward shareholders. The board approved a 20% increase in the quarterly cash dividend to $0.15 per share, payable on June 17 to stockholders of record as of June 5. “We started calendar 2026 with great execution, driving strong sequential and year-over-year revenue growth in all our end markets, while expanding gross and operating margins,” said CEO Irving Tan.

AI Workloads Fuel Persistent Demand for Hard Disk Drives

Tan explicitly linked the company's performance to the AI boom, noting that virtually every AI workload—from training and inference to agentic and physical AI—generates data that must be stored persistently and cost-efficiently on hard disk drives. This demand has extended visibility for Western Digital and its rivals. Seagate, the other major HDD manufacturer, reported that its nearline capacity is almost fully allocated through calendar 2027, a level of forward visibility rare in the hardware sector. Seagate’s Mozaic HAMR technology has locked hyperscalers into multi-year contracts, a dynamic that is now flowing directly into financials. Western Digital’s Q4 outlook calls for revenue growth of 36% to 44% year-over-year, with non-GAAP gross margin expected between 51% and 52%. CFO Kris Sennesael said the company expects revenues of $3.65 billion at the midpoint, with non-GAAP EPS of $3.25.

Capital Discipline and Shareholder Returns Take Center Stage

The company’s balance sheet has strengthened considerably, allowing it to deploy robust free cash flow toward shareholder returns. The 20% dividend increase signals management’s confidence in the durability of the business. Seagate is pursuing a similar strategy, using its $953 million in quarterly free cash flow to rapidly retire debt and prepare for aggressive shareholder returns. Non-GAAP gross margin at Seagate reached an all-time high of 47.0% in its fiscal third quarter, up from 36.2% a year earlier. Western Digital’s GAAP diluted EPS of $8.20 far exceeded the non-GAAP figure of $2.72, reflecting significant one-time items. The non-GAAP measure provides a clearer picture of ongoing operational performance.

Industry-Wide Supply Constraints Bolster Pricing Power

The storage sector is experiencing an unprecedented supply-demand imbalance. Seagate management confirmed that nearline capacity is almost fully allocated through calendar 2027 under build-to-order contracts that lock in both configuration and pricing, effectively eliminating the inventory-glut risk that has historically plagued the industry. This pricing power is evident in margin expansion. Western Digital’s Q4 gross margin guidance of 51% to 52% would represent a further improvement from the 50.5% non-GAAP margin achieved in Q3. Seagate’s non-GAAP operating margins reached 37.5%, with operating expenses flat at $296 million, or 9.5% of revenue. “Our business continues to strengthen with visibility extending as we continue to build momentum across all our end markets,” said Sennesael.

Technology Leadership Drives Competitive Advantage

Seagate’s second-generation Mozaic 4 platform delivers up to 44 terabytes per drive, over 30% more capacity than first-generation drives, with minimal change to the bill of materials. This cost structure gives Seagate a clear product advantage over Western Digital in mass-capacity HDDs. However, Western Digital is also innovating, with Tan emphasizing the company’s role in building storage infrastructure for the AI-driven data economy. The company partners with the world’s leading hyperscalers, cloud service providers, and enterprises to enable reliable storage solutions at scale. The economics of flash memory remain prohibitive for cold storage workloads involved in large language model training and archival, ensuring that HDDs will remain essential for the foreseeable future.

Outlook: Earnings Momentum Expected to Continue

Western Digital’s Q4 guidance implies continued strong performance, with revenue growth decelerating slightly from 45% to roughly 40% but margins expanding. Seagate’s Q4 non-GAAP EPS guidance of $5.00 came in nearly 26% above Wall Street consensus, reflecting the sector’s upward trajectory. Seagate’s full fiscal 2026 non-GAAP EPS is tracking toward approximately $14, with earnings compounding across each quarter rather than relying on a single strong print. This operational efficiency provides a fundamental floor that decouples the stock from short-term technical volatility. For Western Digital, the dividend increase and strong cash flow provide a buffer against potential downturns, while the AI-driven demand cycle shows no signs of abating. The company will host a conference call to discuss results and outlook at 1:30 p.m. Pacific on the day of the earnings release.

Structural Re-Rating Underway as Storage Becomes AI's Backbone

The storage sector is undergoing a structural re-rating as AI infrastructure buildout consumes supply faster than the industry can respond. Both Western Digital and Seagate are setting terms with customers rather than reacting to market fluctuations, a shift that has historically led to sustained profitability. With nearline capacity locked through 2027 and gross margins at or near record levels, the risk of a sudden inventory correction has receded. Investors are now watching whether Western Digital can close the technology gap with Seagate’s HAMR platform while maintaining its own margin trajectory. The dividend increase and strong free cash flow generation suggest that management believes the current demand cycle has durability. For now, the data center buildout shows no signs of slowing, and storage remains a critical bottleneck in the AI supply chain.
