Western Digital (WDC) Citi’s 2026 Global TMT Conference summary

Market trends and demand outlook

• Shift from consumer/PC-driven cycles to cloud and AI-driven secular growth, with 90% of business now tied to cloud storage.

• Exabyte demand growth expected to exceed 25% CAGR over the next five years, with current demand outpacing supply.

• Customers are seeking long-term agreements (LTAs) extending to 2030 and beyond, reflecting strong, predictable demand.

• No signs of a digestion period; hyperscaler CapEx continues to rise, with data storage needs compounding over time.

• Industry structure now features long-term planning and less cyclicality, with customers planning data center builds five years ahead.

Technology and product roadmap

• Recent and upcoming product transitions include 32TB ePMR, 40TB next-gen ePMR, first-gen HAMR up to 44TB, and future 50+TB drives.

• High-Bandwidth drives are being sampled and will launch with 50+TB products, targeting 2x to 8x performance improvements.

• HAMR technology is in qualification with four hyperscale customers, with initial shipments expected in early 2027 and ramping through the year.

• Ongoing investment in head/media technology and automation to support higher areal density and more platters per drive.

• KV caching and higher-performance HDDs are seen as opportunities to encroach on flash storage segments.

Financial performance and strategy

• Pricing per terabyte has increased 18–19% year-over-year, with further room for improvement as value and performance rise.

• Most of 2027 and parts of 2028–2029 are under LTAs, with flexibility for volume and pricing upside.

• Gross margins are in the mid-50s and operating margins in the mid-40s, with no perceived ceiling as higher capacity drives lower costs.

• Long-term cost per terabyte reductions targeted at ~10% annually, though near-term headwinds exist due to input cost increases.

• CapEx is forecasted at 4–6% of revenue over five years, focused on technology, media, and automation investments.
