Western Digital, a prominent player in data storage solutions, is experiencing a period of robust expansion, largely driven by the escalating requirements of artificial intelligence (AI) data centers. These facilities, essential for training and operating sophisticated large language models, demand immense storage capacities for processing vast datasets. The company's recent financial performance highlights this trajectory, showcasing significant revenue and earnings growth. This surge positions Western Digital as a key beneficiary of the current boom in AI infrastructure, suggesting a promising outlook for its market valuation and investor returns.
AI data centers necessitate substantial storage for both training advanced models and serving inference applications. This necessitates extensive hard-disk drives (HDDs) and NAND flash-based solid-state drives (SSDs). While industry peers like Micron Technology and SanDisk have capitalized on this demand, Western Digital has outperformed, achieving a 465% stock rally over the past year. This impressive growth reflects its ability to meet the critical storage needs of the AI sector, making it a compelling entity for closer examination.
Western Digital's fiscal 2026 fourth-quarter report, ending July 3rd, revealed a 36% year-over-year revenue increase, reaching $12.9 billion. The company's non-GAAP operating margin expanded by nearly 13 percentage points to 37.3%, driven by a favorable supply-demand environment in the storage market. This strong operational performance translated into a 104% rise in adjusted earnings per share (EPS) to $10.22.
Looking ahead, Western Digital projects continued impressive growth, with an anticipated $4.1 billion in revenue for the current quarter, representing a 45% increase from the previous year. The non-GAAP EPS is expected to jump by 125% to $4.00. Management's comments during the August earnings call indicate sustained demand, with HDD capacity for 2026 already sold out and discussions underway for long-term supply agreements extending to 2029, 2030, and even 2031. This trend underscores the enduring need for storage solutions to support the ongoing expansion of AI data centers.
Industry forecasts further reinforce Western Digital's favorable position. Morgan Stanley predicts a prolonged HDD supply cycle through at least 2028, suggesting potential for further price increases due to worsening supply constraints. They estimate that annual HDD demand growth of 40%-50% significantly outpaces the 30%-35% annual increase in supply. This imbalance could drive the price per terabyte for high-capacity nearline storage drives from approximately $15 to $25-$30 within the next three years, substantially boosting Western Digital's profitability. Analysts widely anticipate robust earnings growth for the company, aligning with these market dynamics.
Despite its remarkable performance, Western Digital’s current valuation of just 17 times earnings suggests considerable upside. Analysts project the company's earnings per share to increase by nearly 4.5 times between fiscal 2026 and fiscal 2029. More bullish predictions from Morgan Stanley anticipate a tenfold increase in EPS between 2025 and 2028. Should Western Digital achieve consensus estimates of $44.83 EPS in three years and trade at the Nasdaq-100 index's forward earnings multiple of 26, its stock price could reach $1,165. This represents a 165% increase from its current level, highlighting its potential for substantial future gains.
Western Digital's compelling growth trajectory, driven by the escalating demands of the AI sector, coupled with its attractive valuation, positions it as an enticing investment opportunity. The company's ability to secure long-term supply agreements and capitalize on a tightening storage market points to a sustained period of robust financial performance. Investors seeking exposure to the high-growth AI infrastructure market may find Western Digital's prospects particularly appealing.
