Material Changes vs. Prior Period
- Revenue Growth: Net revenue increased 27% year-over-year, driven by a 3% increase in units sold and a 19% increase in average selling price (ASP) due to a shift toward higher-capacity drives. Cloud revenue grew 31%.
- Profitability Surge: Net income from continuing operations jumped 673% to $1.182 billion. This was significantly boosted by a $611 million unrealized gain on the retained interest in SanDisk (marked to fair value).
- Margin Expansion: Gross margin improved by 710 basis points to 43.5%, attributed to higher volumes, product cost reductions, and improved pricing.
- Operating Expenses: SG&A expenses decreased 32% ($66 million) due to the separation of SanDisk, which eliminated certain corporate overhead roles and reduced service fees.
- Customer Concentration: The top 10 customers now account for 77% of net revenue, up from 65% in the prior year.
Guidance, Outlook, and Risks
- Capital Allocation: The company repurchased $553 million of common stock during the quarter. A $2.0 billion share repurchase program remains active with $1.30 billion available. A cash dividend of $0.125 per share was declared for payment in December 2025.
- SanDisk Stake: WDC expects to monetize its remaining stake in SanDisk within one year of the separation date. In June 2025, 21.3 million shares were exchanged for $800 million of term loan debt.
- Tax Environment: The effective tax rate was 12% (vs. 37% prior year), driven by the tax-free nature of the SanDisk gain and favorable international tax provisions. New legislation (OBBBA) allows immediate expensing of domestic R&D starting in 2026.
- Key Risks:
- Trade Policy: Ongoing uncertainty regarding U.S. tariffs and retaliatory measures.
- Convertible Debt: $1.6 billion in 2028 Convertible Notes are currently classified as current liabilities because the conditional conversion feature was triggered; holders may convert through December 31, 2025.
- Legal: An appeal is pending regarding a patent infringement lawsuit (SPEX Technologies) where a jury previously awarded damages, though the court later reduced the award to nominal damages.
Investor Verification Checklist
- SanDisk Gain Sustainability: Verify the volatility of the $611 million unrealized gain on the retained SanDisk interest and its impact on future earnings.
- Convertible Note Conversion: Monitor the conversion status of the $1.6 billion 2028 Convertible Notes, which are currently due within 12 months due to stock price triggers.
- Customer Concentration: Assess the risk associated with the top 10 customers representing 77% of revenue.
- Debt Structure: Review the impact of the $1.6 billion term loan reduction via the SanDisk share exchange and the remaining debt maturity profile.
- Tax Rate Normalization: Evaluate the likelihood of the effective tax rate returning to the statutory 21% once the one-time SanDisk gain is excluded.
