Sandisk Surges 600% as AI Storage Demand Fuels $93.9 Billion Contract Backlog

Sandisk Secures $93.9 Billion in Long-Term Supply Agreements

Sandisk has emerged as an unexpected winner in the AI infrastructure boom, signing eight strategic agreements worth at least $93.9 billion with six customers4

4

. These long-term contracts average four years in duration, with some extending as long as five years2

2

. Chief Financial Officer Luis Visoso confirmed the contracts can include fixed-price periods, upside participation, downside protection, and third-party financial guarantees3

3

. The company projects that half of its output will be under such contracts in fiscal 2027, rising to two-thirds in fiscal 20284

4

.

This shift represents a fundamental change in how the NAND flash market operates. Large cloud and data center operators increasingly want predictable supply rather than quarterly price negotiations3

3

. The agreements provide customers with greater supply certainty while giving Sandisk better visibility into future demand, stabilizing revenue streams in what was traditionally a volatile commodity market.

AI Inference Workloads Reshape NAND Flash Demand

AI inference workloads are fundamentally repositioning NAND flash from a commodity storage medium to a system-critical component of AI infrastructure1

1

. Data centers now account for more than half of industry demand for NAND flash memory semiconductors2

2

. Speaking at the Goldman Sachs Communacopia + Technology Conference, Sandisk executives explained that larger AI models and longer context windows are increasing the need for scalable storage solutions for AI data centers3

3

.

CEO David Goeckeler highlighted that artificial intelligence is increasingly running into a "memory wall" as models grow larger and AI-driven storage demand intensifies3

3

. Technologies such as retrieval-augmented generation and KV cache are expanding NAND's role in AI infrastructure. In AI systems, expanding model sizes and data-intensive inference increasingly prioritize density, performance, endurance, and supply certainty over the lowest absolute price1

Data Center Revenue Quadruples as Enterprise SSD Portfolio Expands

Sandisk reported fiscal fourth-quarter revenue of $8.97 billion, exceeding the $8.39 billion expected4

4

. Data center revenue more than quadrupled from the preceding quarter to $2.98 billion4

4

, demonstrating the speed at which the business mix is transforming. The company achieved a non-GAAP gross margin of 84.6%5

5

, a remarkable expansion from 26.4% a year earlier.

Sandisk spent several years expanding its enterprise SSD portfolio, positioning itself to benefit as data center demand becomes a larger share of the NAND market3

3

. The company projects fiscal first-quarter 2027 revenue of $10.3 billion to $10.8 billion4

4

, suggesting continued momentum. North American cloud customers have revised upward their predictions for business SSD demand, with enterprise SSD orders expected to surpass already-high third-quarter levels in the fourth quarter.

Rosenblatt Initiates Coverage with $2,400 Price Target

Rosenblatt initiated coverage of Sandisk with a buy rating and a $2,400 price target, implying 36% upside from Monday's close1

1

. Analyst Kevin Cassidy noted that new AI compute platforms are creating an opportunity to reposition NAND from commodity storage to a more system-critical component1

1

. The stock jumped 6.29% following the initiation, trading near $1,877 and adding roughly $16 billion of market value5

5

.

Rosenblatt's call aligns with Wall Street consensus. Of the 28 analysts covering Sandisk, 24 have a buy or strong buy rating on the stock1

1

. The stock has surged 644% year to date1

1

, and over 1,800% in the last 12 months2

2

, driven by the AI frenzy and a global shortage of NAND flash memory and enterprise SSDs.

BiCS8 and BiCS10 Technologies Provide Competitive Edge

Sandisk has an edge over competitors due to its 3D NAND flash memory technology BiCS8 and BiCS10 platforms that pack many bits into a given square millimeter of silicon without requiring much production space1

1

. Cassidy believes this can support a favorable bit-cost curve and sustain a performance-and-cost advantage in AI-oriented enterprise storage1

1

.

In August, Sandisk and its joint-venture partner Kioxia announced a high-performance 2-terabit QLC 3D flash technology for AI and data-intensive applications4

4

. According to Sandisk tests, the next-generation BiCS10 technology is designed to boost memory density by 60%, improve read and write bandwidth by 100%, and increase interface performance by 33% compared to BiCS84

4

. The company produces substantially all of its flash chips in Japan through its joint-venture structure with Kioxia2

.

High Bandwidth Flash Targets AI Memory Bottleneck

Sandisk is developing High Bandwidth Flash (HBF) specifically for AI inference workloads to address what Goeckeler calls the "memory wall" problem3

3

. The company sees an opportunity to use its NAND expertise and HBF technology to help address memory bottlenecks by combining greater storage density with higher bandwidth and durability3

3

.

Goeckeler clarified that HBF is not designed to replace high-bandwidth memory (HBM). Instead, Sandisk aims to combine NAND's density with higher bandwidth and durability to address memory constraints as inference workloads scale3

3

. The company plans to place HBF samples with customers next year, potentially opening another revenue stream as AI models continue expanding.

Capital Allocation Balances Investment with Shareholder Returns

Sandisk authorized a $14 billion share-repurchase program, taking its total remaining authorization to $15.5 billion4

4

. At its August investor day, the company shared a long-term development plan focused on its NAND technological roadmap, customer alliances, and capital allocation4

4

. Sandisk aims to return 100% of surplus cash to shareholders after investing in the business, while maintaining an 80% gross margin target and a 50% free cash flow margin3

3

.

The company continues to favor share repurchases over dividends for returning cash to shareholders3

3

. Despite the aggressive buyback program, Sandisk is not reducing investment in capacity or technology. The combination of capacity and technology investment with aggressive shareholder returns forms the core of the company's strategy as it navigates the structural shift in the semiconductor industry driven by AI infrastructure buildout.
