Primary Catalysts & Risks for WDC’s Q4 Earnings

Western Digital’s fiscal fourth-quarter performance is likely to have benefited from continued strong demand from cloud service providers, fueling nearline HDD and NAND capacity purchases. In the fiscal third quarter, cloud accounted for 87% of total revenues, reaching $2 billion, up 38% year over year. Broad investments from hyperscale cloud/data center customers remain a tailwind.

Its 11-disk drives, offering up to 26TB (CMR) and 32TB (Ultra SMR), are rapidly ramping up, with more than 800,000 units shipped in the fiscal third quarter, and more than 1 million expected for the June quarter. Management is working closely on HAMR technology with two hyperscale customers and continues to receive positive and encouraging feedback on its drives. Long-term agreements are now in place with two major customers through mid-2026. Considering these factors, WDC anticipates sequential revenue growth in the fiscal fourth quarter, driven by strong data center demand.

Management expects the rise of generative AI-driven storage deployments to lead to a client and consumer device refresh cycle and increase content growth in smartphones, gaming, PCs and consumer devices over the long term. Growing AI adoption is likely to boost storage demand across both HDD and Flash at the edge and core, creating many business opportunities. To expand its Flash business further, the company has established a separate entity, Sandisk.

However, the ongoing macroeconomic volatility and uncertainty caused by the damaging impact of levying tariffs and escalating global trade conflicts are likely to weigh on its performance in the to-be-reported quarter by creating further cloud demand fluctuations in areas such as the enterprise segment and parts of its distribution and retail business.

To address these changing macroeconomic and geopolitical challenges, Western Digital has outlined strategies. In the short term, it has assembled cross-functional teams to minimize disruptions and reduce the impact of tariffs on customers and operations. At the same time, management is adopting a disciplined approach by evaluating the long-term effects of supply chain adjustments to stay agile, resilient and prepared for the future. Despite broader uncertainties, demand from hyperscale customers remains strong amid a constrained supply situation.

Also, rising expenditures are likely to weigh on its margins. For the fiscal fourth quarter, WDC expects operating expenses to rise slightly sequentially to $330–$340 million due to higher variable pay, new hires post–flash business spinoff and more R&D investments.

Key Recent Developments

In May 2025, Western Digital drove a new era of storage innovation by advancing infrastructure solutions tailored for AI/ML, software-defined storage and disaggregated storage. With a focus on hyperscale cloud service providers, enterprises and Storage-as-a-Service vendors, the company’s Platforms Business delivers both high-capacity JBODs (Just a Bunch of Disks) and high-performance EBOF (Ethernet Bunch of Flash) NVMe-oF solutions to power intensive data workloads.

Western Digital teamed up with Ingrasys, a subsidiary of Foxconn Technology Group, to transform the way storage and networking are deployed at scale. The initiative aims to engineer a Top-of-Rack (TOR) Ethernet Bunch of Flash (EBOF) switch with embedded storage—a new frontier in fabric-attached, disaggregated infrastructure designed to meet the surging data demands of AI and high-performance workloads.

Western Digital boosted shareholder value by launching a new $2 billion share buyback program in May, highlighting its strong capital allocation strategy focused on long-term returns for investors.
