Western Digital earnings grow faster than revenue
Western Digital released its quarterly filing for the period ended October 2, 2026 on October 23. The results cover the first quarter of its 2027 fiscal year, rather than a calendar-year quarter.
Operating income more than doubled while revenue increased approximately 55%. That difference indicates that a larger share of sales translated into operating profit than in the comparable period. Gross margin was approximately 57.8%, and cash generated from operations totaled $1.60 billion.
Operating cash generation gives the storage company resources for research and development, although it is not the same measure as cash remaining after capital investment.

Cloud storage is central to the business
Western Digital's nearline enterprise hard drives serve hyperscale cloud providers, making demand for mass-capacity storage a key part of the business. Artificial intelligence and cloud computing are important uses behind the need to store larger volumes of data.
The company's technology roadmap includes energy-assisted recording and heat-assisted magnetic recording, alongside OptiNAND and UltraSMR technologies intended to improve storage capacity and efficiency. Those development efforts should be distinguished from completed product launches or guaranteed future sales.
Western Digital also supplies smart-video and network-attached-storage products, extending its business beyond hyperscale data centers.
Large customers remain a material exposure
The top 10 customers generated 64% of quarterly revenue. That concentration leaves Western Digital sensitive to changes in purchasing by a relatively small group of buyers, even with products serving several storage markets.
The earlier-year figure was 73%, but the filing also identifies a change in customer-concentration methodology. The comparison therefore should not be treated as a straightforward measure of customer diversification.
Competition and dependence on a limited number of qualified component suppliers remain operating risks. Strong quarterly profitability does not eliminate the potential effect of disrupted supply or changing customer orders.
Conclusion
Western Digital's quarter combined substantial revenue growth with a faster increase in operating profit. The next quarterly results will provide the next test of whether cloud-storage demand and cash generation can sustain that performance.
