Seagate beats expectations and raises its target price as the HDD supply-demand gap and AI data demand continue to strengthen earnings leverage

Overview

This report reviews Seagate's F4Q26 results. JPMorgan believes Seagate once again delivered a beat-and-raise result, extending the strong fundamentals seen since F3Q26: data center demand, AI-driven data generation and retention, cloud capital expenditures, and industry supply discipline are jointly supporting upward trends in HDD pricing and margins. JPMorgan therefore raises its earnings estimates and target price.

Core views

The core view is that the HDD industry's demand-supply mismatch continues to widen. Seagate benefits from data center Nearline demand, incremental data storage demand generated by AI workloads, and Edge IoT pricing opportunities arising from higher prices for competing NAND storage. The company maintains a leading position in HAMR and Mozaic technology platforms. Mozaic 3+ has been qualified and entered volume production with major cloud customers, while Mozaic 4+ is ramping at two major CSPs and expanding qualification. The report maintains its Overweight rating, believing that both earnings revisions and valuation support are in place.

Analysis framework

The report combines earnings comparisons, guidance comparisons, pricing trends, supply-demand dynamics, and valuation multiples. It first compares F4Q26 actual revenue, gross margin, operating margin, and EPS with JPMe and consensus expectations; then analyzes F1Q27 revenue, EPS, gross margin, and pricing guidance; subsequently incorporates the latest pricing and demand trends into FY27-FY29 forecasts; and derives the target price using approximately 18x 2028E EPS.

Methodology notes

• Valuation methodsP/E-Based Price Target

  P/E-based target price

  JPMorgan values 2028E EPS at approximately 18x P/E to derive a Dec-27 target price of $1,240. The report believes this multiple is above historical levels but supported by hyperscale cloud capital expenditure demand, while remaining relatively conservative versus certain AI-related suppliers.

• Earnings ReviewBeat-and-Raise Review

  Beat and raise guidance

  The report compares F4Q26 actual results with JPMe and consensus expectations, and compares the company's F1Q27 guidance with pre-report expectations to assess whether earnings estimates require upward revisions.

• Industry AnalysisDemand-Supply Gap

  Demand-supply gap

  The report focuses on assessing the gap between data center and AI-related storage demand and Nearline HDD supply. It believes long-term agreements have locked in most supply through CY28, with customer planning extending into CY29 and beyond.

  Directly covered security

  Strengths

  Benefits from data center- and AI-driven data storage demand, tight Nearline HDD supply, price increases, HAMR/Mozaic technology progress, and long-term customer agreements.

  Weaknesses

  The share price has risen significantly, and FY26A P/E is approximately 47.9x, making near-term valuation relatively sensitive to earnings delivery and the sustainability of guidance.

  Comparison

  The report believes the target multiple is above historical levels but remains more conservative than those of certain AI-related suppliers, reflecting the relatively less aggressive nature of HDD pricing actions.

  Risks

  A slowdown in cloud AI infrastructure capital expenditures, a narrowing NAND-HDD cost gap leading to faster migration to flash, higher NAND density, and a narrowing supply-demand gap.

• Pricing growthF4Q26 price per EB +11% year over year; F1Q27 implied at least +20% year over yearPricing improvement is the core variable behind the upward revisions to revenue and margins.

• FY28E adjusted EPS$60.00Raised from $45.40, an increase of 32.1%.
• Target price$1,240Raised from $1,095, based on approximately 18x 2028E EPS.

Impact & implications

For investment implications, the report positions Seagate as a beneficiary of AI data center capital expenditures and HDD supply discipline. If pricing gains, Nearline demand, and long-term purchasing agreements with cloud customers continue, the company's FY27-FY29 revenue, margins, and EPS could continue to grow rapidly. However, the current share price has risen significantly, making valuation more sensitive to cloud capital expenditures, NAND substitution risk, and the sustainability of pricing.

Risks

• A slowdown in cloud capital expenditures or AI infrastructure investment could weaken expectations for HDD industry demand growth.
• A narrowing NAND-HDD cost gap could accelerate migration to flash storage.
• Faster-than-expected increases in NAND density could pressure expectations for Seagate's stock.
• If price increases prove unsustainable, the upside to gross margin and EPS revisions could reverse.
• Changes in customers' long-term plans and supply commitments could weaken the Nearline supply-demand tightness thesis.

What to watch

• Whether actual F1Q27 revenue falls within or exceeds the $4,000-4,200mn guidance range.
• Whether year-over-year growth in price per EB reaches the implied guidance of at least 20%.
• Whether gross margin approaches approximately 57% and operating margin approaches approximately 50%.
• Whether evidence continues to strengthen that Nearline supply is locked in through CY28 and customer planning extends into CY29 and beyond.
• Qualification and volume ramp progress for Mozaic 4+ beyond the two major CSPs.
• The pace of AI capital expenditures by cloud service providers and data center storage procurement plans.
