Western Digital (WDC.US) reported its fiscal 2026 third-quarter results after the U.S. market close on April 30. The company achieved revenue of $3.3 billion, a 45% year-over-year increase, exceeding the high end of its guidance. Earnings per share reached $2.72, surging 97% year-over-year, nearly doubling. In terms of exabyte shipments, Western Digital delivered 222 EB of capacity to customers during the quarter, a 34% year-over-year increase. The cloud business was the primary growth driver, with revenue reaching $3.0 billion, accounting for 89% of total revenue and growing 48% year-over-year. On the profitability front, driven by the transition to a product portfolio focused on higher-capacity drives and the execution of its pricing strategy, Western Digital's gross margin for the quarter soared to 50.5%, an improvement of 1040 basis points year-over-year. CFO Kris Sennesael noted during the call: "We delivered a strong gross margin in the third quarter, breaking through the 50% range." The company expects next-quarter revenue of $3.65 billion, with gross margin further rising to a range of 51% to 52%. Diluted earnings per share are projected to be $3.25.

CEO Irving Tan stated that as AI workloads extend from model training to large-scale inference, coupled with the rise of Agentic AI and physical AI frameworks, data generation is at an inflection point. This will drive a "step-function growth" in storage demand, and the company maintains high confidence in long-term annual storage capacity growth exceeding 25%.

**Structural Shift in AI Development: "Every Inference Creates Data That Must Be Stored"** Beyond the impressive quarterly figures, management delved into the underlying logic of data storage in the AI era. CEO Irving Tan emphasized that AI workloads are extending from "training" to "large-scale inference," with data generation at a critical inflection point. Tan explained: "Inference creates data, AI agents consume and generate more data, and physical AI creates data and trains synthetic models that generate even more data. Ultimately, this cycle accelerates." He pointed out that inference is expected to account for two-thirds of all AI computing this year. The resources (compute/memory) used to create tokens are recycled, but the data created must be stored. Every token, every prompt, creates data that requires persistent, scalable, and cost-effective storage, with the vast majority residing on Hard Disk Drives (HDDs).

Regarding future growth potential, Irving Tan expressed strong conviction: "These forces are not simply additive; they form a compounding cycle... This reinforces our belief that the long-term compound annual growth rate (CAGR) for data storage will exceed 25%."

**Order Visibility Extends to 2029, Gaining Pricing Power** Amid robust demand, Western Digital's order visibility and pricing power are undergoing a qualitative change. Discussing the highly watched price trends and long-term agreements (LTAs), management shared encouraging information. The price per terabyte increased by 9% year-over-year this quarter. Commenting on this trend, Irving Tan stated: "Our long-term visibility continues to improve, with agreement terms now extending into calendar years 2028 and 2029." CFO Kris Sennesael emphasized that the company's pricing logic is to provide customers with "predictable pricing" to avoid volatility. "Predictable pricing enables our customers to make long-term architectural decisions. This is the foundation supporting the structural changes we discuss for the future of the HDD industry." Additionally, incremental demand beyond the base capacity committed in LTAs will be subject to different pricing mechanisms, providing the company with "opportunities for incremental pricing upside."

**Technology Roadmap and Capacity Readiness: Dual Advance with Ultra SMR and HAMR** Regarding technology iteration and cost reduction, Western Digital's cost per exabyte decreased by 10% year-over-year this quarter. To address the impending data deluge driven by AI, the company stated it currently has no plans to increase "unit capacity" but is fully committed to boosting areal density. Irving Tan revealed: "We are accelerating our development pace. We now have four customers engaged in Heat-Assisted Magnetic Recording (HAMR) qualification, with very positive feedback. The 40TB EPMR drive is also undergoing qualification with three customers and is expected to enter volume production in the second half of 2026." Notably, the adoption rate of Ultra SMR technology is accelerating. Irving Tan predicted: "We plan to have all major customers qualified on Ultra SMR by the end of calendar year 2027... By the end of fiscal year 2027, nearly 60% of all the exabyte capacity we ship will be based on Ultra SMR."

**Optimizing Capital Structure: Selling Sandisk to Reduce Debt Significantly, Dividend Increased by 20%** On the balance sheet front, Western Digital completed significant repairs in Q3. By monetizing 5.8 million shares of Sandisk stock, the company reduced its debt by $3.1 billion, leaving only $1.6 billion in convertible debt outstanding. The company now holds $2.0 billion in cash and cash equivalents, resulting in a net cash position of $450 million. Based on a strong free cash flow margin of 29%, and quarterly free cash flow of $978 million, the Board of Directors approved a 20% increase in the cash dividend to $0.15 per share and committed to continuing to return excess free cash flow to shareholders through dividends and share repurchases. The company still holds 1.7 million shares of Sandisk stock and plans to complete their monetization by the end of calendar year 2026.
