Sandisk Locks the Cycle: $93.9B of Contracted NAND, an 84.6% Gross Margin, and a New Playbook for Memory

The NBM machine: from quarterly auction to a contracted franchise

Sandisk's fiscal Q4 — revenue of $8,965M, up 51% sequentially and 372% year-over-year, with non-GAAP EPS of $39.25 — was the cleanest proof yet of a reinvention that management began in earnest barely two quarters ago. Every headline number came in above the high end of guidance, and the company repurchased $4.5B of stock in the quarter. But the defining event was structural, not cyclical: the New Business Models, or NBMs, have moved from concept to the dominant way Sandisk now transacts with its largest customers.

Two quarters ago, Sandisk had five NBMs. Today it has eight, spanning datacenter and edge, with a minimum of $93.9B in expected revenue at floor pricing and a remaining performance obligation of $59.8B at quarter end — $91.1B including two agreements signed after the close. Three of the five new contracts are with net-new customers, and two expand existing agreements, with customers already coming back for more. It is no coincidence that signing deals is now the top-ranked keyword in Sandisk's own 2026Q3 trajectory.

We expect our NBMs to represent more than 50% of our bits in fiscal year 2027, and approximately 2/3 of our bits in fiscal year 2028. NBMs are quickly becoming our predominant way of doing business.

The architecture is the genuinely novel piece: $16.5B of financial guarantees — cash deposits and instruments, mostly held by third-party financial institutions — designed to protect Sandisk if a customer fails to satisfy purchase obligations, with the guarantee ratio rising as each agreement matures. Pricing mixes fixed and variable elements, with floors and ceilings. This is a NAND supplier behaving like an enterprise software vendor. As Goeckeler summarized, “we have over 4 years of visibility now.” — David V. Goeckeler, CEO · 2026-08-05

The Era of Inference turns NAND into a strategic product

Underneath the contracting sits the demand story that makes it credible. Sandisk frames AI — and specifically the shift to Agentic AI and inference — as essentially a memory problem. “AI is fundamentally a memory-centric storage-intensive problem. Every AI interaction creates content that must be stored, retrieved and served at low latency.” — David V. Goeckeler, CEO · 2026-08-05 The numbers back the narrative: datacenter grew from roughly 12% of bits a year ago to 38% exiting FY26, and datacenter revenue hit $2,977M, up 103% sequentially. The company now models the NAND market above $300B in CY26 and approaching $500B in CY27, with datacenter growing from ~30% to ~50% of TAM. This is a theme the entire market is voting on — KV Cache was a top-10 global keyword in Q2, and high-bandwidth flash has been a consistent advancer theme in the price tape. Sandisk's own technology leadership rides that wave: BiCS 8 now the majority of bit production, with BiCS 10 already announced and high-bandwidth flash positioned as a potential rearchitecture of the memory-storage hierarchy.

Durability is the price — and the market is still weighing it

The tape tells a more ambivalent story than the headline numbers. Sandisk is up 4,334% since its February 2025 listing, but sits 31.6% below its June 25 peak of $2,335, with the last eight weeks down about 27%. The first-quarter guide — $10.3–10.8B revenue, 83–85% gross margin, EPS of $44–46 — was read as a bit lighter than expectations, and shares traded down in the after-market session. Directly challenged on why gross margin guidance steps slightly below the 84.6% print even as pricing ticks up, Goeckeler gave the clearest articulation yet of the strategy's trade-off.

We want to get this kind of boom and bust out of it. It doesn't work for anybody. So we're executing what we said we were going to do last quarter. We're committing supply to customers that are willing to commit for years in advance at the economics we guided to.

That “fair return” — David V. Goeckeler, CEO · 2026-08-05 framing — "I think mid-80s gross margin, I would characterize as a fair return" — is the crux of the market debate: by locking in ~80%-plus NBM margins with floors and ceilings, Sandisk is deliberately trading spot-price upside for durability. In the January call, Goeckeler acknowledged how hard this transition is — “to change the business practices of an industry is almost like really hard to do... But I do think it's happening.” — David V. Goeckeler, CEO · 2026-01-29 By April he was already committing to a goal, saying of the NBM share of supply: “I definitely think it can get above 50%, and we have a desire to drive it quite high.” — David V. Goeckeler, Chief Executive Officer · 2026-04-30 Two months later, that promise is effectively delivered.

The buyback engine is now explicit and programmatic: 2.84M shares repurchased for $4.5B in the quarter, a new $14B authorization bringing total remaining to $15.5B, and a stated intent to be “very consistent in our execution of this program.” — David V. Goeckeler, CEO · 2026-08-05 With the balance sheet now net cash and free cash flow conversion surging, Sandisk has the firepower to keep the returns machine running even as it invests in BiCS 8/10 transitions. The fundamentals file lags one quarter, but the shape is unmistakable: revenue up 251% year-over-year with gross margin expansion of 37 points and a 49.4% free cash flow margin in the most recent filed quarter.

The open question is whether the market ultimately pays up for the cash generation and contracted visibility — or keeps pricing Sandisk as a cyclically peaked memory vendor whose new model merely capped the upside at the top. The NBM framework, backed by $93.9B of minimum revenue, makes the strongest case yet that the former is the right read. But the 32% drawdown says the market is not yet convinced.
