Performance & Track Record

Company Performance Context (GAAP)

MetricFY2023FY2024FY2025
Revenues ($MM)$7,384 $6,551 $9,097
Gross Margin (%)18% 23% 35%
Operating Margin (%)-5% 6% 21%
Net Income ($MM)-$529 $335 $1,469
STX TSR (fixed $100)$147.42 $254.60 $358.36

Highlights:

  • HDD shipments 595 exabytes (+49%); nearline 84% of exabytes .
  • Cash from operations $1.1B; FCF $818M; returned $600M via dividends .
  • Reduced total debt by $684M; ended with $5.0B long-term debt and $891M cash .

Compensation & Incentive Program Analysis

  • Pay mix emphasizes at-risk equity; ≥50% of LTIs performance-based; annual bonus settled in RSUs with +30% premium to preserve cash and align with shareholders .
  • FY2025 added standalone rTSR metric to PSUs, alongside ROIC, strengthening alignment to shareholder returns .
  • Say-on-Pay support strong: 88% (2022), 96% (2023), 96% (2024); FY2025 maintained strategy without material changes .
  • No single-trigger CIC; no excise tax gross-ups; clawbacks compliant with SEC/Nasdaq plus misconduct recovery .
  • Peer group framework spans storage/semis/hardware (ADI, AMAT, KLAC, MU, WDC, etc.); FY2026 changes: removed AMAT/JNPR; added ON Semiconductor and Pure Storage .
  • Independent consultant (Semler Brossy); committee independence; no interlocks .

Risk Indicators & Red Flags

  • Combined Chair/CEO elevates governance scrutiny; mitigated by Lead Independent Director and fully independent committees .
  • CEO pay ratio 861:1 in FY2025 (global workforce skew to Asia ops) .
  • Anti-hedging/pledging policy reduces misalignment/leveraged risk; Section 16 compliance noted (no CEO late filings) .
  • Equity acceleration potential creates event-driven exposure in CIC scenarios (see Employment Terms) .

Expertise & Qualifications

  • Deep technology and operations expertise across storage manufacturing, R&D, and sales; Ph.D. in Solid State Physics; board experience at Cirrus Logic .

Work History & Career Trajectory

  • Joined Seagate in 1996; progressed from engineering to executive roles culminating in CEO (2017); broad scope across operations, technology, and commercial leadership .

Compensation Committee Analysis

  • Composition: Independent directors; Chair Jay Geldmacher; members Cannon, Conyers, Haggart; annual risk assessment finds programs not reasonably likely to cause material adverse effect .
  • Uses Semler Brossy; benchmarks broadly without fixed percentile; prioritizes role scope, internal equity, retention, and pay-for-performance .

Investment Implications

  • Alignment: Strong ROIC+rTSR PSU design, equity-settled EPB, and robust ownership/clawback policies support pay-performance linkage amid FY2025 turnaround .
  • Retention/Supply Overhang: Near-term vesting of EPB RSUs and one-year RSUs (Aug 2026) plus sizable outstanding PSUs/RSUs could create episodic selling pressure as awards vest; anti-pledging reduces forced-sale risks .
  • Event-Driven: Large CIC equity acceleration ($33.9M PSUs; $13.6M RSUs; $13.3M options) indicates sensitivity to strategic transactions; no gross-ups but cutback mechanism applies .
  • Governance: Combined Chair/CEO post-AGM warrants monitoring; mitigated by Lead Independent Director and independent committees; strong say-on-pay track record reduces near-term governance discount .
