Full Analysis
Western Digital Corporation (WDC) shares have surged 893% over the past year, significantly outperforming peers like Seagate Technology (STX) and Teradata (TDC). The rally is primarily attributed to the AI boom driving massive demand for data storage. Western Digital recently split into two public companies: Western Digital focusing on hard disk drives (HDD) and flash storage, and SanDisk as an independent entity. In February 2025, WDC completed this separation, with SanDisk now leveraging its expertise for AI-driven opportunities. Financial results for the fiscal third quarter were strong, driven by AI adoption shifting from training to inference. Western Digital reported revenues of $3.34 billion, a 45% year-over-year increase. Adjusted earnings per share (EPS) reached $2.72, up 97% year-over-year and 28% sequentially, exceeding management's guidance of $2.30. The growth was fueled by operating leverage, reduced interest costs, and a more efficient tax structure, effectively doubling EPS over the last year. Technology advancements remain a key focus with Western Digital shipping 222 exabytes in the quarter, a 34% increase from the prior year. This included 4.1 million next-generation ePMR drives totaling 118 exabytes with capacities up to 32TB. The company is also advancing areal density gains through HAMR and ePMR roadmaps, aiming for long-term storage demand CAGR above 25%. To support this, Western Digital acquired intellectual property and talent to strengthen in-house laser development capabilities. Management has taken steps to strengthen the balance sheet following the separation from SanDisk. In the fiscal third quarter, Western Digital sold 5.8 million SanDisk shares, using proceeds to reduce debt by $3.1 billion. This left only $1.6 billion in convertible debt outstanding. Combined with $2 billion in cash and equivalents, the company ended the quarter with a net cash position of $450 million. Additionally, the board authorized an additional $4 billion for share repurchases starting in February 2026, with roughly $484 million remaining from previous authorization. The company increased its quarterly dividend by 20% to 15 cents per share and repurchased approximately 2.9 million shares worth $752 million during the quarter. Firm purchase orders with top seven customers are secured through 2026, supported by multi-year commercial agreements with three of its top five customers extending into 2027 and 2028. These commitments highlight strong customer relationships and confidence in capacity to meet growing exabyte-level demand driven by agentic AI, synthetic data, and physical AI systems from robotics and autonomous vehicles. The separation allows WDC to focus directly on HDD and data-center infrastructure opportunities while SanDisk focuses on flash memory, improving overall execution and profitability over time.
