SanDisk reveals 88% of new revenue came from AI data centers as demand for memory chips soars

Data Center Revenue Accounts for 88% of SanDisk's Quarterly Growth

SanDisk reported fiscal first-quarter revenue of $11.03 billion, marking a 23% sequential increase from $8.97 billion in the previous quarter1

1

. The company added approximately $2.07 billion in quarterly revenue, with data center revenue accounting for $1.83 billion of that increase—representing 88.3% of total growth1

1

. Data center revenue jumped 61% sequentially to $4.80 billion from $2.98 billion, now comprising 43.5% of total sales compared to 33.2% in the prior quarter1

. This concentration reveals how AI infrastructure spending by hyperscalers is reshaping the memory maker's business model and creating significant exposure to cloud providers expanding their AI capabilities.

AI Demand Drives Exponential Year-Over-Year Performance

The company delivered adjusted earnings per share of $49.51, exceeding Wall Street's expectation of $46.673

. Revenue soared 378% year-over-year from $2.31 billion, while net income reached $8.1 billion compared to $112 million in the same period last year4

4

. The adjusted operating margin climbed to 80.4% from 79.2% in the previous quarter, reflecting strong pricing power as hyperscalers remain willing to pay premium prices for data storage amid constrained capacity3

NAND Flash Memory Technology Advances Support AI Infrastructure

SanDisk's technology leadership centers on its BiCS architecture for NAND flash memory production. The company highlighted BiCS8 as the current industry benchmark for performance and density across TLC and QLC, featuring CMOS Directly Bonded to Array (CBA) architecture that enables the performance required by AI data-center customers2

2

. Management announced advancements including BiCS9 and BiCS10, alongside achieving a milestone with High Bandwidth Flash (HBF) designed specifically to support AI infrastructure2

. These technological developments position the company to capture increasing demand as AI workloads become more data-intensive and require greater storage capacity.

Mixed Performance in Edge and Consumer Segments

While AI-driven demand for memory products surged, SanDisk's other business segments showed divergent trends. Edge business revenue, which includes storage products for smartphones, PCs, and other devices, increased approximately $400 million to $5.83 billion, representing just 7% sequential growth1

Long-Term Customer Agreements Provide Visibility Through 2030

SanDisk emphasized the importance of its New Business Model (NBM) partnerships, which provide multi-year customer agreements extending beyond fiscal year 20302

2

. These long-term contracts aim to reduce NAND's traditional boom-and-bust cycles by creating predictable demand, planning capabilities, and cash flow1

1

. Management stated that customer signals now extend well into the next decade, with structural AI demand expected to drive NAND's role significantly higher by decade's end2

2

. The company announced an 8-for-1 stock split with additional shares distributed on November 19, while maintaining its strategy to remain debt-free and return 100% of excess cash to shareholders through share repurchases2

Guidance Signals Continued Growth Amid Margin Questions

For the second quarter of fiscal 2027, SanDisk guided for revenue between $12.2 billion and $12.6 billion, with adjusted earnings per share expected between $55 and $572

. Wall Street analysts had projected second-quarter revenue of $12.31 billion and adjusted earnings of $53.60 a share4

4

. Despite strong results, the stock traded near flat in after-hours trading, with investors noting that adjusted free cash flow margins declined from 56.2% to 51.6% even as sequential growth slowed3

3

. The concentration risk remains significant—if hyperscalers slow AI data-center buildout, delay projects, or reduce storage purchases, the business segment driving most of SanDisk's growth could lose momentum1
