Material Changes vs. Prior Period
- Revenue Growth: Net revenue increased 36% to $12.9 billion, driven by a 25% increase in exabytes sold and an 8% increase in average selling prices (ASPs). Cloud revenue grew 38% to $11.5 billion, representing 89% of total revenue.
- Profitability Surge: Net income from continuing operations jumped to $9.4 billion (from $1.6 billion in 2025). This was primarily driven by a $6.5 billion mark-to-market gain on the retained interest in SanDisk, compared to a $772 million loss in the prior year.
- Margin Expansion: Gross margin improved by 10.1 percentage points to 48.9%, attributed to a mix shift toward higher-capacity drives, better cost structures on new products, and improved pricing.
- Debt Reduction: The Company significantly deleveraged, reducing total debt from $4.7 billion to $1.1 billion. This was achieved through debt-for-equity exchanges using retained SanDisk shares and cash settlements.
- Capital Allocation: The Company repurchased $2.59 billion of common stock and paid $174 million in dividends. It also settled convertible notes and redeemed senior notes.
Guidance, Outlook, and Risks
- Outlook: Management expects long-term demand for data storage to grow, fueled by AI and hybrid data workloads. Customers are extending commercial arrangements, improving demand visibility. Capital expenditures are expected to average 4% to 6% of net revenue over the next five years.
- Dividends & Buybacks: A quarterly cash dividend program is active ($0.15/share declared post-year-end). A share repurchase program with $3.26 billion remaining authorization is in place.
- Key Risks:
- Customer Concentration: The top 10 customers accounted for 73% of revenue in 2026; the top three accounted for 44%.
- Supply Chain: Dependence on a limited number of suppliers for critical components (e.g., recording heads, media) and exposure to geopolitical trade restrictions.
- Technology Transition: Risks associated with ramping new technologies (HAMR, OptiNAND) and achieving manufacturing yields.
- Convertible Notes: $710 million of 2028 Convertible Notes remain outstanding and are currently convertible, classified as current liabilities.
Investor Verification Checklist
- SanDisk Gain Sustainability: Verify the extent to which the $9.4 billion net income is driven by the one-time $6.5 billion gain on SanDisk shares versus core HDD operating performance.
- Convertible Note Conversion: Monitor the settlement of the remaining $710 million in 2028 Convertible Notes, which are currently convertible and classified as current debt.
- Cloud Customer Concentration: Assess the risk of revenue volatility given that 89% of revenue comes from the Cloud segment and the top 10 customers represent 73% of sales.
- Tax Holiday Expirations: Review the status of tax holidays in Thailand and Malaysia, which are critical to the Company's effective tax rate (5% in 2026).
- Capital Expenditure Execution: Confirm that planned investments in heads and media operations align with projected demand for high-capacity drives.
