Read MoreHide Full Article

Key Takeaways

  • Western Digital's fiscal Q1 gross margin rose 1,420 basis points to 58.1%, driven by pricing and product mix.
  • WDC expects fiscal Q2 gross margin of 60-61%, with revenues of $5.1 billion, up 69% at the midpoint.
  • Higher-capacity HDDs, favorable pricing and rising areal density support WDC's continued margin expansion.

Western Digital Corporation (WDC - Free Report) continues to demonstrate strong gross margin expansion, supported by favorable pricing, growing demand for high-capacity hard disk drives (HDDs) and disciplined operational execution. The company remains confident about sustaining this momentum as it advances its technology roadmap and transitions customers toward higher-capacity products.

In the first quarter of fiscal 2027, Western Digital's non-GAAP gross margin expanded 1,420 basis points year over year to 58.1%, with incremental gross margins exceeding 80%. This improvement primarily reflected a favorable product mix, strong pricing across its portfolio and operational efficiencies. Notably, the year-over-year increase in average selling price (ASP) per terabyte accelerated to 28% from the high teens in the preceding quarter.

Management identified three key factors supporting sustained gross margin expansion. First, a favorable pricing environment continues to benefit the company, with contractual price increases under long-term agreements and stronger spot pricing amid tight supply conditions. Pricing improvements are also evident across its client and consumer businesses.

Second, the transition toward higher-capacity drives is strengthening profitability, as these products command higher ASPs per drive. Third, increasing areal density allows Western Digital to ship more exabytes without incurring the additional fixed costs associated with expanding unit production capacity.

Western Digital expects second-quarter fiscal 2027 gross margin between 60% and 61%, indicating further sequential improvement. Revenues are projected at $5.1 billion, plus or minus $100 million, implying 69% year-over-year growth at the midpoint.

The company also anticipates further ASP-per-terabyte increases over the next three to four quarters, although management acknowledged that pricing growth could eventually moderate. Meanwhile, higher DRAM and NAND input costs remain a near-term challenge, potentially limiting cost-per-terabyte reductions below the company's long-term target of approximately 10% annually.

Nevertheless, continued pricing strength, higher-capacity product adoption and improving areal density position Western Digital to sustain gross margin expansion. Management remains optimistic about longer-term profitability, supported by robust storage demand and ongoing technology transitions.
