Triple-Beat + 1 Hyperscaler Signs Full CY27 Agreement + Dividend +25% + ePMR Shipments 2.2M: Maintaining Outperform

Published: By A.N. Burrows WDC | Q1 FY2026 Earnings Analysis

Key Takeaways

  • Q1 FY26 triple-beat: revenue $2.8B (+27% YoY) above guide high $2.8B; non-GAAP GM 43.9% (+660bp YoY; +260bp QoQ) above guide 41-42%; EPS $1.78 vs guide midpoint $1.54. FCF $599M despite $331M one-time repatriation tax payment.
  • Customer visibility extended materially: Top 7 hyperscalers POs through H1 CY26; all top 5 with full CY26 POs; 1 hyperscaler signed agreement covering ALL of CY27. The CY27 LTA is the first multi-year customer commitment disclosure — proves the structural shift from quarterly transactions to multi-year contracted demand.
  • ePMR 26TB/32TB shipments scaled to 2.2M units (vs 1.7M Q4) — continued aggressive ramp. HAMR qualification starts with 1 hyperscaler in 1H CY26; expanding to 3 hyperscalers through CY26; volume production ramp-up 1H CY27. Next-gen ePMR qual Q1 CY26.
  • Capital return accelerating: Dividend RAISED 25% to $0.125/share. Q1 buybacks $553M (6.4M shares) — quadrupled vs Q4's $150M. $785M total returns since program launch Q4 FY25. Net leverage <1x with $2B cash + $4.7B debt.
  • Rating: Maintaining Outperform. Q4 thesis fully validated and extended. CY27 LTA + dividend +25% + ePMR 2.2M units + HAMR on track collectively support multi-year compounding. Fair value range raised to $115-145 (~14-18x FY27 EPS power of ~$8.20). Post-print $107.

Key Topics & Management Commentary

1. Multi-Year LTAs Extending — 1 Hyperscaler Signs Full CY27

The structural visibility breakthrough. Top 7 hyperscalers now have POs through H1 CY26; all top 5 covered for full CY26; 1 hyperscaler signed agreement covering ALL of CY27. The CY27 LTA is the first multi-year customer commitment disclosure in WDC's standalone history.

"Our top 7 customers have now provided purchase orders extending throughout the first half of calendar year 2026. And 5 of them have provided purchase orders covering all of calendar year 2026. I'm also pleased to share that one of our largest hyperscale customers has signed an agreement covering all of calendar year 2027."
— Irving Tan, CEO

Assessment: The CY27 LTA is the structural validation of WDC's strategic value to hyperscalers. Once one hyperscaler signs multi-year, others typically follow within 2-4 quarters. By exit FY26, expect majority of top 5 customers under multi-year LTAs.

2. HAMR Qualification Plan + Next-Gen ePMR Bridge

HAMR qualification starting 1H CY26 with 1 hyperscaler; expanding to 3 hyperscalers through CY26; volume production 1H CY27. Next-gen ePMR qualification Q1 CY26 — provides smooth technology transition while HAMR completes qualification.

Assessment: The ePMR + HAMR parallel roadmap is the right strategic posture. Customers get smooth capacity scaling through next-gen ePMR (CY26) while HAMR completes its longer qualification cycle (CY27 ramp). De-risks the HAMR transition while sustaining capacity growth.

3. Capital Return Quadruples

Q1 share repurchases $553M (6.4M shares) vs Q4's $150M (2.8M shares). Dividend RAISED 25% to $0.125/share. Cumulative returns since program launch $785M.

"This marks a 25% increase over the dividend announced in April and speaks to the long-term confidence we have in our business."
— Kris Sennesael, CFO

Assessment: Capital return acceleration validates the FCF generation confidence. With net leverage <1x already, the company can sustain high buyback + dividend cadence through FY26 and beyond.

4. ePMR Ramp Continues at Pace

2.2M ePMR drives shipped Q1 (vs 1.7M Q4). 26TB CMR and 32TB UltraSMR continuing to scale as customers transition from older 24TB drives.

Assessment: The ePMR ramp is the bridge revenue driver. Each 2-3TB capacity increment delivers measurable TCO improvement and customer migration accelerates.

5. New Rochester Integration & Test Lab

New 25,600 sq ft Integration & Test Lab inaugurated in Rochester, Minnesota. Mirrors hyperscale customer production environments. Enables collaborative product development + accelerated qualification cycles.

Assessment: Investment in qualification infrastructure signals long-term hyperscaler partnership focus. Faster qualification cycles = quicker time-to-market for new capacity tiers.
