Western Digital CEO Irving Tan Talks AI Storage Demand
Brief
Western Digital CEO Irving Tan framed the company’s position amid the AI storage surge by citing strong Q4 FY26 financials (>$40% revenue growth, >54% gross margin) while acknowledging short-term supply timing pressures. He emphasized sustained demand from hyperscalers and neo-clouds — better than 25% CAGR over five years — and described WD’s product-led response: increasing bits per drive rather than unit production. Tan highlighted the engineering work behind media and head recipes as WD moves from 32 TB drives to 40 TB drives this quarter (roughly a 30% capacity uplift) and stressed close customer qualification. He noted LTAs are in place through 2029, customers are seeking 2029–2031 commitments (including requests on the order of 600 exabytes for 2031), and pricing mechanics remain under negotiation. Tan reiterated HDDs remain central to cloud AI infrastructure (~80% of cloud storage).
Why it matters
Speaker 3 (Irving Tan, Western Digital CEO) reported Q4 FY26 results with over 40% revenue growth, gross margin above 54%, and very strong cash-flow generation, while noting quarterly supply transitions affected near-term expectations.
Key details
- Tan said hyperscalers and 'neo-clouds' show robust demand and the company sees better than 25% CAGR in storage demand over the next five years.
- Western Digital's strategy is to grow capacity per drive rather than unit volumes: the company is shipping 32 TB drives today and will begin shipping 40 TB drives this quarter (≈30% capacity increase) — requiring media and head engineering and close customer qualification, according to Tan.
- Tan confirmed existing long-term agreements (LTAs) locked to 2029, customers are asking about 2029–2031 commitments (example: a customer seeking 600 exabytes in 2031), and commercial/pricing constructs (base price plus step-tier models) are still under negotiation; he also stated ~80% of cloud storage is on HDDs.
