Results Beat Expectations, but Technology Transition and Elevated Expectations Weigh on Near-Term Share Performance

Overview

The report believes Western Digital's latest quarterly fundamentals remain strong: revenue was in line with expectations, gross margin and EPS exceeded expectations, and HDD pricing, cost, and supply-demand conditions all remained favorable. However, investors previously had high expectations for continued price increases and margin expansion, and 22% capacity growth was below the company's long-term target, so the solid next-quarter guidance may still be viewed by the market as insufficient. Goldman Sachs expects the stock to face near-term pressure, but believes the company can execute well on the 40TB ePMR ramp and HAMR qualification plans, and maintains its Neutral rating.

Core views

Core conclusions include: first, HDD industry supply discipline and cloud business demand provide medium-term fundamental support, and the company remains in a state of undersupply; second, price per TB increased by high double digits YoY, while cost per TB declined 8% YoY, driving gross margin to 54.4%; third, the ePMR and HAMR transitions will increase areal density and support capacity growth, but will cause shipment cadence volatility in the near term; fourth, Seagate has completed most of its HAMR transition and has stronger pricing momentum and potential share performance, making it the better relative allocation; fifth, despite slight upward revisions to CY2026/27 EPS forecasts, the slower growth outlook still prompted a reduction in the valuation multiple.

Analysis framework

The report compares actual quarterly revenue, revenue by business, gross margin, and EPS with Goldman Sachs forecasts and Visible Alpha consensus expectations, and assesses expectation gaps in conjunction with next-quarter guidance; it then analyzes pricing, unit costs, supply discipline, and the 40TB ePMR and HAMR roadmaps, before determining the target price through normalized EPS and a P/E multiple and making a relative investment comparison with Seagate.

Methodology notes

• Earnings analysisComparison of actual results with consensus expectations

  Expectation gap analysis

  Compares actual quarterly revenue, revenue by business, gross margin, and non-GAAP EPS with Goldman Sachs forecasts and Visible Alpha consensus expectations to identify the sources of beats or misses.

• Operating analysisTechnology roadmap and capacity transition analysis

  ePMR and HAMR product iteration

  Assesses the impact of the technology transition on capacity growth, pricing, and execution risk based on 40TB ePMR shipments, the FY3Q27 penetration target, 50TB product plans, and the progress of HAMR qualification by initial customers.

• Industry analysisSupply-demand and unit economics analysis

  Supply discipline, price per TB, and cost per TB

  Evaluates the sustainability of HDD profitability and gross margins by considering current shipments below demand, restrained industry capacity expansion, changes in price per TB, and the decline in cost per TB.

• Valuation analysisP/E target price method

  Normalized EPS multiplied by target P/E

  Applies a 22x target P/E multiple to normalized EPS of $28.00 to derive a target price of about $615; the target multiple was reduced from the previous 23x to reflect slower growth.

• Relative value analysisPeer comparison

  Relative allocation between Western Digital and Seagate

  Compares the two companies' HAMR transition progress, pricing momentum, and potential market share changes, leading the report to prefer Buy-rated Seagate.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Western Digital Corp. (US.WDC)

  Primary research subject

  Strengths

  Stable HDD supply-demand environment, high cloud business exposure, rising pricing per TB, declining unit costs, and the 40TB ePMR ramp are expected to support future capacity and margin growth.

  Weaknesses

  Quarterly capacity growth was below the long-term target, the ePMR and HAMR transitions may cause near-term shipment volatility, and current earnings expectations are high.

  Comparison

  Compared with Seagate, Western Digital's HAMR transition progress is slower, and it may face marginal share pressure over the next year.

  Risks

  Delays in HAMR qualification or mass production, technology challenges, industry over-shipment, valuation multiple contraction, and weak consumer business.

• Seagate Technology

  Peer comparison and preferred allocation target

  Strengths

  Has completed most of the HAMR technology transition, has stronger pricing momentum, and may gain incremental market share over the next year.

  Weaknesses

  The report does not provide detailed financial data for its current quarter, and it is also exposed to HDD industry demand and supply cycles.

  Comparison

  Goldman Sachs rates Seagate Buy and explicitly states its preference for Seagate over Neutral-rated Western Digital.

  Risks

  Weakening HDD demand, increased industry supply, or HAMR product execution falling short of expectations.

Key data

• Consumer business revenue$187mnBelow Goldman Sachs' forecast of $214mn and consensus expectations of $203mn.
• Quarterly capacity growth22% YoYBelow the company's long-term target of over 25%; management believes this was mainly affected by technology transition and product mix.
• Increase in price per TBHigh double digits YoYPartly driven by improved pricing opportunities for non-nearline products.
• Decline in cost per TB8% YoYTogether with pricing improvement, this drove quarterly gross margin up to 54.4%.
• Next-quarter revenue guidance$4.10bn midpointClose to Goldman Sachs' forecast of $4.17bn and consensus expectations of $4.04bn.
• Next-quarter gross margin guidance55% to 56%Above Goldman Sachs' forecast of 54.1% and consensus expectations of 54.0%.
• Next-quarter non-GAAP EPS guidance$3.85 to $4.15Midpoint of $4.00, above Goldman Sachs' forecast of $3.94 and consensus expectations of $3.80.
• 40TB ePMR transition targetApproximately 50% by FY3Q27By then, approximately half of nearline HDD bit shipments are expected to come from 40TB ePMR products.
• Target price$615Lowered from $650, based on a 22x P/E multiple and normalized EPS of $28.00.

Impact & implications

In the near term, even with strong earnings and margin performance, insufficient capacity growth and revenue guidance broadly in line with expectations may still trigger profit-taking against a backdrop of elevated expectations. In the medium term, cloud storage demand, industry supply discipline, rising price per TB, and technology upgrades can continue to support Western Digital's profitability; however, Seagate currently has stronger relative advantages in HAMR transition completion, pricing momentum, and market share. Therefore, the report acknowledges that WDC has absolute upside at the current price, but does not believe its risk-reward is superior to the preferred peer.

Risks

• The HAMR roadmap may be delayed, customer qualification may be postponed, or new technology challenges may arise.
• The ePMR and HAMR transitions may cause temporary volatility in capacity shipments and product mix.
• Industry over-shipment could worsen supply-demand conditions and lead to valuation multiple compression.
• Seagate may gain incremental market share with more mature HAMR products.
• Elevated investor expectations mean that guidance in line with expectations could also trigger a negative share price reaction.
• Consumer business revenue was below expectations, indicating that some end markets remain weak.

What to watch

• The ramp pace of 40TB ePMR products over the next few quarters and the approximately 50% transition target by FY3Q27.
• Qualification progress and mass production timetable for HAMR products among the first four customers.
• Whether quarterly capacity growth can return to the long-term target of over 25%.
• Delivery of price per TB, cost per TB, and the 55% to 56% gross margin guidance.
• The magnitude of pricing adjustments after long-term agreement renewals and contract pricing flexibility.
• Whether the industry continues restrained capacity expansion and whether the company's state of shipping below demand can continue.
• Changes in nearline HDD share and pricing momentum between Western Digital and Seagate.
• Further adjustments to CY2026/27 EPS forecasts and changes in the target valuation multiple.
