Western Digital (NASDAQ:WDC) reported robust financial performance driven by surging demand for enterprise data center storage within the expanding AI infrastructure ecosystem. The company delivered first-quarter revenue of $4.4 billion, representing a 55% year-over-year increase, with gross margins reaching 58.1%, up significantly from the prior year. This top-line expansion was fueled by strong exabyte growth and a favorable pricing environment that supported incremental gross margins above 80%. For fiscal second quarter 2027, Western Digital expects revenue to reach $5.1 billion at the midpoint, reflecting a 69% year-over-year growth rate. Management forecasts diluted non-GAAP earnings per share of $5.80 plus or minus $0.20, with gross margins anticipated between 60% and 61%. The company anticipates operating expenses between $400 million and $410 million, driven by increased product qualification activity for its high-density storage solutions. Beyond revenue growth, Western Digital has executed a significant balance sheet optimization strategy. Total debt decreased by 22.59% quarter-over-quarter to US$922m, resulting in a net debt position of negative US$392m following the repayment of $1.17bn in total debt. The company also returned substantial capital to shareholders through $1.32bn in common stock repurchases and $56m in dividends, demonstrating strong cash flow generation and financial flexibility despite elevated short-term inventory levels. Looking ahead, Western Digital aims to complete qualifications for its first-generation HAMR product with two hyperscale customers in the first quarter of calendar 2027, with volume shipments beginning in the first half of that year. The company projects capital expenditures to modestly exceed its five-year target range as it invests in head and media technology and factory automation to support the anticipated acceleration in exabyte supply growth through fiscal years 2027 and 2028.
