Published: By A.N. Burrows WDC | Q2 FY2026 Earnings Analysis

Key Takeaways

  • Q2 FY26 triple-beat: revenue $3.0B (+25% YoY) above guide high $3.0B; non-GAAP GM 46.1% (+770bp YoY; +220bp QoQ) above guide; EPS $2.13 (+78% YoY) — first quarter above $2 in WDC standalone history. Operating margin 33.8% (+540bp YoY).
  • LTA visibility extends to CY28: Top 7 hyperscalers POs through all of CY26; 3 of top 5 customers now under multi-year agreements — 2 through CY27, 1 through CY28. Multi-year contracted revenue base expanding each quarter.
  • ePMR 26TB CMR + 32TB UltraSMR shipments scaled to 3.5M+ units (vs 2.2M Q1) = 103 exabytes. Total exabytes 215 (+22% YoY). HAMR qualification + next-gen ePMR qual underway with different hyperscalers. Acquired IP assets and talent for internal HAMR laser capabilities.
  • Innovation Day Feb 3, 2026 in NYC — 1 week post-print. Updated roadmaps for HAMR + ePMR; financial model update. UltraSMR-enabled JBOD platforms launched with software ecosystem partners. Strategic investment in Qolab (quantum hardware) — extends WDC's material science + precision manufacturing into adjacent markets.
  • Rating: Maintaining Outperform; raising conviction to High. Three consecutive triple-beats + LTA extensions + dividend confidence + Innovation Day catalyst + HAMR on track. Fair value range raised to $185-220 (~14-17x FY27 EPS power of ~$13). Post-print $163.

Key Topics

1. LTA Visibility Extends to CY28

Top 7 hyperscalers with POs through all of CY26. 3 of top 5 customers under multi-year LTAs: 2 customers through CY27, 1 customer through CY28. Each successive quarter, more hyperscalers convert from POs to multi-year LTAs.

"We have firm purchase orders with our top seven customers through calendar year 2026. We also have in place robust commercial agreements with three of our top five customers, two through calendar year 2027 and one through calendar year 2028. These agreements indicate a strong trust that we have built with our customers and confidence in our ability to meet their exabyte needs."
— Irving Tan, CEO

Assessment: The CY28 LTA extension is the next structural milestone. By exit FY26, expect majority of top 5 hyperscalers under multi-year LTAs through CY27-29. This converts WDC into a contracted revenue franchise with downside protection.

2. EPS +78% YoY — First Quarter Above $2

Q2 EPS $2.13 is the first quarter above $2 in WDC standalone history (post-spinoff Feb 2025). The 78% YoY EPS growth on 25% revenue growth = operating leverage compounding (GM +770bp YoY; OpEx as % of revenue -120bp QoQ).

3. HAMR Internal Laser Capability — IP/Talent Acquisition

WDC acquired IP assets and talent to develop internal laser capabilities for HAMR. Laser quality is the most critical component for HAMR performance.

Assessment: Internalizing laser capability removes a critical supplier dependency and enables faster iteration on HAMR areal density improvements. Strategically de-risks the HAMR transition.

4. Innovation Day Feb 3, 2026 NYC

1-week-out catalyst preview. Updated HAMR + ePMR roadmaps; financial model update. UltraSMR-enabled JBOD platforms launched with software ecosystem partners.

Assessment: Innovation Day will likely raise long-term financial model (originally 38% GM target). Q2 already at 46.1% GM — the medium-term model needs updating to reflect AI-driven structural margin expansion.

5. Qolab Quantum Investment

Strategic investment in Qolab — combines WDC's material science + precision manufacturing with Qolab's quantum hardware design. Aims to advance next-generation nanofabrication processes for qubit performance and scalability.

Assessment: Optionality investment, not material to FY26-27 results. Demonstrates WDC's R&D capabilities can extend beyond HDDs into adjacent precision manufacturing markets.

6. Capital Return Continues

Q2 buybacks $615M (3.8M shares). $1.4B total returns since program launch Q4 FY25. Net debt position $2.7B; net leverage well below 1x.
