Full Analysis
Western Digital Corp. shares fell approximately 2.7% to $469.42 on Thursday as investors locked in gains following a historic fiscal 2026 performance that turned hard-disk drives into a dominant AI trade. The stock had previously surged over 650% year-to-date, but the market is now digesting how far the rally has run after the company reported record-breaking financial results and raised guidance for the coming year. For the fiscal year ended July 3, Western Digital reported revenue of $12.92 billion, a 36% increase from the prior year, while non-GAAP earnings more than doubled to reflect strong operational efficiency. Free cash flow reached $3.51 billion, representing a 27% margin on sales, and the company returned $3.1 billion to shareholders through dividends and buybacks, ending the fiscal year in a net cash position with capital spending of only $418 million. The fourth quarter served as the primary driver of this success, delivering $3.75 billion in revenue which was 44% higher than the previous year and beat Street expectations of $3.69 billion. Non-GAAP earnings per share were $3.56 versus a consensus of $3.29, with non-GAAP gross margins expanding to 54.4%. Despite these robust fundamentals, the stock experienced a classic sell-the-news reaction, dropping more than 5% in regular trading and another 11% after hours. Management highlighted that demand for their storage solutions is compounding rather than cyclical, noting that roughly 80% of data stored in hyperscale data centers currently resides on hard disk drives. CEO Irving Tan emphasized the company's ability to scale innovation, while CFO Kris Sennesael pointed to disciplined execution and broadening demand across all end markets as key factors driving their long-term growth trajectory. Looking ahead, Western Digital provided first-quarter fiscal 2027 guidance expecting revenue between $4.0 billion and $4.2 billion, implying a year-over-year sales growth of 42% to 49%. The company plans to ship 44-terabyte HAMR drives in the first half of calendar 2027 and aims for 40-terabyte ePMR drives to comprise over half of nearline exabytes by the third quarter of fiscal 2027, with a roadmap extending past 100 terabytes. Analyst targets remain widely dispersed between $428 and $900, reflecting a debate between bulls who see Western Digital as a scarce bit factory essential for AI infrastructure and bears concerned about the high valuation multiple of roughly 19x trailing earnings. The company is now positioned as a capacity-constrained supplier with long-term customer agreements stretching toward 2031, asking investors to pay a premium for visibility through the end of the decade.
