J.P. Morgan: Accelerating HDD Pricing, Reiterates Overweight on WDC and STX
Strong AI-driven demand combined with production discipline has placed HDD pricing in an accelerating upcycle, prompting institutions to substantially upgrade earnings forecasts and price targets for both companies.
- HDD industry pricing is expected to accelerate year-over-year over the coming quarters, with month-over-month growth remaining in the low-to-mid single digits.
- Three AI-related drivers—training, inference, and physical AI—support long-term demand, with EB growth remaining above 25%.
- Strict industry capacity expansion discipline ensures short-term pricing power is not suppressed by long-term agreements (LTAs).
- FY27 earnings forecasts are upgraded by 10%-15%, with WDC target price raised to $650 and STX to $920.
- WDC currently trades at a lower valuation, implying 33% upside compared to STX's 13%.
Report interpretation
Overview
J.P. Morgan released an HDD industry update stating that the pricing environment is strengthening and accelerating. This trend surpasses sell-side consensus and represents further upside beyond already elevated buyer expectations. Based on more optimistic pricing assumptions, the institution raised revenue and gross margin forecasts for Western Digital (WDC) and Seagate (STX), subsequently upgrading FY27 earnings expectations by 10%-15%. Although market expectations for the HDD sector are already high, the report argues that structural demand driven by AI and strict capacity discipline leave significant room for fundamental improvement in both companies, leading to the reiteration of Overweight ratings and substantial price target increases.
Core views
Accelerating pricing is the core driver behind this upgrade. The report notes that both WDC and STX achieved their first year-over-year double-digit pricing increases in the March quarter, with expectations for wider YoY gains in subsequent quarters. Month-over-month price growth is projected to stabilize in the low-to-mid single-digit range. This continuous month-over-month improvement will support incremental margins at high levels. Specifically, WDC's FY27 per-EB pricing growth forecast has been revised from +8% to +11%, while STX's is revised from +7% to +10%. Strengthening pricing power is seen as gradually departing from historical cyclical patterns, exhibiting a new normal with greater sustainability and acceleration. Demand side presents multiple structural tailwinds. Beyond traditional cloud storage needs, three AI-related trends are reshaping the HDD demand curve: first, hyperscale cloud providers continue to generate massive datasets through ongoing AI training and re-training; second, the shift towards inference and agentic AI generates significant volumes of new output data requiring archival storage; third, physical AI applications like robotics and autonomous driving produce continuous video/sensor data and synthetic data. These factors collectively keep industry EB shipment growth rates above 25%. Supply discipline and LTA mechanisms ensure earnings visibility. While some customers seek long-term agreements (LTAs) extending to 2032 to lock in supply, the report emphasizes that LTAs are primarily priced based on annual order visibility and will not hinder near-term price increases. More importantly, both WDC and STX have maintained strict capital expenditure discipline without expanding unit capacity. This tight supply-demand balance is expected to sustain a strong and expanding pricing environment for years. Earnings upgrades and valuation re-rating are occurring simultaneously. Higher pricing forecasts directly translate to dual upgrades in revenue and gross margins. WDC's FY27 gross margin forecast was raised from 55.3% to 58.6%, and STX's from 51.6% to 54.5%. This drove FY27 earnings expectations up by 10%-15%, with both companies projected to see FY27 earnings growth exceeding 90% and FY28 growth exceeding 55%. While execution fundamentals are comparable between the two, WDC offers greater potential return space (33% vs. STX's 13%) due to its lower current valuation multiple.
Analysis framework
The report employs a typical 'quantity-price decomposition' framework to analyze the HDD industry. Unlike previous cycle analyses focusing solely on shipment volume, this analysis centers on the 'price' dimension, predicting margin inflection points by tracking month-over-month and year-over-month unit price changes. Simultaneously, the institution incorporated supply-side capital expenditure discipline (Capex Discipline) as a key variable to validate pricing sustainability, encapsulated as 'No New Capacity + Rigid Demand = Return of Pricing Power'. Additionally, in terms of valuation, the institution did not use the HDD historical average P/E but re-anchored it to 'AI Infrastructure Providers', applying a CY27E P/E of 25x参照 to peers with high AI leverage, reflecting the analytical logic of re-evaluating the industry's attributes.
Methodology notes
Decompose revenue growth into separate forecasts for shipment volume (EB Growth) and unit price (Pricing per EB)
In commodity-like industries such as storage, looking solely at total revenue can obscure true drivers. This report explicitly highlights that while EB growth remains above 25%, it focuses on quantifying the accelerating rise in price per EB (e.g., WDC FY27 +11%), precisely identifying that profit elasticity stems from 'price' rather than just 'volume'.
市盈率 valuation based on forward earnings, adjusting target multiples based on changing industry attributes
The report assigns a 25x CY27E P/E, explicitly noting this multiple is significantly higher than the HDD historical average. The rationale is that HDD has become a critical component of AI infrastructure and should align with the average valuation of other covered AI-beneficiary suppliers. This demonstrates how to dynamically adjust valuation anchors based on changes in the fundamental narrative.
Analyze the sustainability of price trends by examining supplier willingness to expand capacity and demand-side long-term contracts
The report specifically emphasizes the combined effect of 'Capacity Discipline' (no expansion) and 'LTA Mechanism' (Long-Term Agreements). Typically, LTAs might lock in prices, but in a seller's market with constrained supply and AI-driven demand, LTAs instead become tools to ensure high prices are realized. This is the key logic for determining that this price hike is not a short-term fluctuation.
Asset mapping & comparison
Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).
- Western Digital (WDC)Beneficiary: Direct beneficiary of accelerating HDD pricing and growing AI storage demand, with relatively more attractive valuation
- Strengths
- Strong storage product portfolio meets data center needs with next-gen HDD solutions; current valuation multiples are lower than peers, offering larger upside space (33%)
- Comparison
- Compared to STX, WDC offers higher potential return at current price levels (33% vs 13%), despite comparable fundamental execution between the two
- Risks

Impact & implications
For the HDD industry, this report confirms a transition from traditional cyclical volatility to a structural growth phase driven by AI. The return of pricing power means earnings quality will be significantly superior to past cycles. For WDC and STX, despite significant stock price appreciation, the pace of earnings upgrades still outstrips market reaction, particularly for WDC which is viewed as the more cost-effective choice at present. This also implies the market may need to re-evaluate the value proportion of the entire storage sector within the AI compute stack, no longer viewing it purely as commodities but as growth assets with certain moats.
Risks
- Slowdown in cloud provider capital expenditures on AI infrastructure could impact HDD demand growth expectations.
- Technology disruption risk: Narrowing cost gap between HDD and NAND flash, or better-than-expected progress in NAND density, could accelerate migration of storage media towards flash.
What to watch
- Whether the month-over-month and year-over-month trends in HDD price per EB continue to accelerate.
- Execution of hyperscale cloud provider AI capital expenditure plans and progress in signing long-term agreements (LTAs).
- NAND flash cost curves and density iteration speeds to assess substitution threats to HDD.
