Western Digital (WDC) Q1 FY2027 Earnings Call: Q&A Summary

Q: What are the remaining milestones for HAMR and what determines the scaling speed?

A: Irving Tan stated that feedback is positive regarding failure rates. Qualifications with two hyperscalers finish in Q1, with two more starting in the first half of calendar 2027. Scaling depends on internal manufacturing and supply chain readiness.

Q: Why was cost per terabyte down 4% to 5% in the December quarter, and what is the long-term view?

A: Kris Sennesael noted the long-term goal is a 10% year-over-year reduction. Near-term costs are impacted by input cost increases for DRAM and NAND, but value engineering is mitigating this.

Q: What is the impact of potential capacity additions by smaller players and industry consolidation?

A: Irving Tan stated there is no change in long-term fundamentals. Demand is strong with a 25% plus CAGR. The company focuses on areal density via head and media technology rather than adding unit capacity.

Q: Is fiscal 2027 exabyte growth in line with long-term ranges, and how does unconstrained demand compare to supply?

A: Irving Tan said the current quarter is the floor for exabyte growth, which will accelerate through the year. Demand remains strong and the supply-demand gap persists.

Q: What is the visibility timeframe and how are customer needs changing?

A: Irving Tan noted that visibility extends to 2030 or 2031 for the top seven customers, with demand signals increasing over time.

Q: What is driving the pricing acceleration in the December quarter?

A: Irving Tan explained that pricing is strong across nearline and non-nearline segments. Higher capacity drives improve customer TCO, and long-term agreements are being repriced.

Q: What is driving the incremental gross margin strength, and is it sustainable?

A: Irving Tan stated sustainability is driven by pricing from agreements and spot markets, up-mixing to higher capacity drives, and shipping more exabytes via higher areal density without increasing unit production.

Q: How is the broadening customer base changing long-term agreement duration and pricing?

A: Irving Tan noted the customer base is diversifying into Frontier AI labs and new cloud players, which is factored into demand signals.

Q: How big is the high-bandwidth drive opportunity?

A: Irving Tan stated it is nascent but a differentiator for workloads like AI inferencing. Commercial pricing structures are currently being developed.

Q: What is the outlook for Physical AI?

A: Irving Tan noted promising signs from autonomous vehicles and robotics, particularly in Asia.

Q: Can competitors easily expand capacity, and what are the bottlenecks?

A: Irving Tan stated the company differentiates through vertical integration of head and media design. Competitors without this integration face harder challenges in scaling.

Q: How big is the new cloud segment, and what if demand softens?

A: Irving Tan identified four growth drivers: cloud, model training, inferencing and agents, and physical AI. If one softens, others compensate.

Q: Is the current pricing growth sustainable?

A: Irving Tan stated there is room for average selling price per terabyte increases for the next three to four quarters.

Q: Why is CapEx modestly above the 4% to 6% range?

A: Irving Tan explained that investments are for head and media technology and factory automation, not for adding unit capacity.

Q: Is the goal to reach mid-30s exabyte growth?

A: Irving Tan stated the company is between product transitions, but new platforms will drive meaningful increases in exabyte supply growth over the next six to eight quarters.

Q: Will HAMR ramp impact average selling price growth?

A: Irving Tan stated HAMR is not discounted and pricing is based on dollars per terabyte.

Q: Does adding head capacity lead to unit capacity increases?

A: Irving Tan explained that head capacity investments are needed for higher areal density and to offset throughput loss from complex HAMR manufacturing.

Q: Do you use external vendors for heads?

A: Kris Sennesael confirmed they use external vendors for lower capacity drives, but high-capacity leading-edge platforms use internal heads.

Q: What is the response to competitors expanding unit capacity?

A: Kris Sennesael stated the focus remains on delivering the highest capacity drives via areal density to provide the best total cost of ownership.

Q: Will non-HAMR nearline capacity expand?

A: Management stated they will continue to ramp and supply the latest ePMR platform in parallel with HAMR, with 50% of nearline shipments expected to be on the 40-terabyte platform by Q3 of fiscal 2027.

Q: How far out is price visibility?

A: Irving Tan noted that long-term agreements provide visibility, but not all exabytes are covered. Pricing is flexible for upside volume.

Q: Is the long-term exabyte growth target of 25% still intact?

A: Irving Tan confirmed the target is greater than 25%.
