Summary

  • Sandisk reported fiscal fourth-quarter 2026 revenue of $8.965 billion, 51% above the prior quarter, and said roughly one-third of the sequential increase came from volume and two-thirds from pricing.
  • Datacenter revenue reached $2.977 billion, more than double Q3’s $1.467 billion, while edge rose to $5.432 billion and consumer fell to $556 million.
  • GAAP gross margin was 84.6%, GAAP net income $6.903 billion and diluted earnings per share $43.97 for the quarter ended 3 July.
  • Since disclosing five New Business Model agreements in April, Sandisk has signed five more: three with new customers and two expansions of previous agreements, making ten disclosed agreements in total.
  • Customer names, volumes, contract values, duration, pricing formulas and product mix remain undisclosed, so the agreements’ protection against a future NAND downturn cannot yet be measured.
  • The board added $14 billion to its repurchase authorization, leaving $15.5 billion available, but the SEC filing says the programme creates no obligation to buy shares and may be suspended.

Datacenter became large enough to change the mix

The most useful number in Sandisk’s 5 August release is not the $8.965 billion headline. It is the $2.977 billion of datacenter revenue beneath it. That segment was $1.467 billion in Q3, so it grew 103% in one quarter. At roughly one-third of total Q4 revenue, it has moved from a promising destination for flash memory to a material determinant of the company’s mix.

The full-year comparison reinforces the shift: datacenter revenue reached $5.153 billion, 437% above the prior year’s $960 million. Yet the company marks the Q4 year-on-year datacenter comparison as not meaningful, and it does not identify the workloads behind the sales. “Datacenter” can encompass several storage uses; the disclosure does not prove that every dollar is tied to generative AI or any named cloud customer.

Price did more work than shipment volume

Sandisk supplied an unusually important decomposition. Approximately one-third of sequential company revenue growth came from higher volumes and two-thirds from higher pricing. That distinction prevents an attractive segment chart from being mistaken for a pure demand curve.

Higher prices can improve revenue and gross profit faster than physical shipments grow. They can also reverse when supply, inventories or purchasing behaviour change. Q4 GAAP gross margin reached 84.6%, 6.2 percentage points above Q3, while GAAP net income rose to $6.903 billion. Those are realised results, but the mechanism says that durability depends on more than continued expansion of data-centre capacity. A serious forecast needs both customer demand and the future balance of NAND supply and price.

Ten agreements are a count, not yet an economic hedge

The New Business Model chronology requires care. Sandisk ended Q3 with three signed agreements and had signed two more before its April earnings call. The August update adds five agreements to that five-agreement baseline: three with new customers and two that expand previously signed arrangements. The disclosed total is ten; it is not ten new agreements signed during Q4.

Management presents multi-year customer engagement as a way to align supply and demand. The public evidence stops before the terms that would show how much risk really moves. There are no customer names, committed volumes, contract values, tenors, price formulas, cancellation rights or product allocations. Without them, investors cannot calculate what proportion of future output is covered, whether prices float with the market, or who bears inventory risk if consumption disappoints.

Edge still supplies most revenue and consumer moved backwards

Datacenter supplied the fastest sequential growth, but it was not the whole business. Edge revenue was $5.432 billion in Q4, up 48% and still about 61% of total revenue. Consumer revenue fell 32% to $556 million. The combination matters: a company can become more exposed to datacenter buyers while the larger edge franchise and a shrinking consumer channel continue to shape inventory and product allocation.

For fiscal 2026, total revenue was $20.248 billion and GAAP net income $11.433 billion. Sandisk’s post-separation accounts give a clear current picture, while earlier periods were prepared on a carve-out basis from Western Digital. That accounting history is another reason to favour segment mechanics and sequential evidence over a single spectacular historical multiple.

A buyback authorization competes with other uses of cash

The board approved an additional $14 billion share-repurchase authorization, taking the remaining authority to $15.5 billion. The regulatory language is narrower than the headline number: purchases may occur in the open market or by other methods, timing and amount depend on conditions, the programme may stop, and approval does not obligate the company to repurchase anything.

Sandisk expects operating cash flow to fund purchases. If executed at scale, the programme could reduce the share count. But it also puts capital allocation beside the demands of technology transitions, supply commitments and working capital in a volatile memory market. The relevant future record is cash actually spent, shares retired and average price—not the authorization alone.

Guidance raises the next-quarter verification threshold

For fiscal Q1 2027, Sandisk guided to revenue of $10.3 billion to $10.8 billion, a non-GAAP gross margin of 83% to 85% and non-GAAP diluted earnings of $44 to $46 a share. These ranges imply that management expects the strong revenue and margin environment to continue into the next period. They are forward-looking, not booked performance.

The next results will therefore test several mechanisms at once. Revenue can reveal whether datacenter momentum and pricing persist. Segment disclosure can show whether growth remains concentrated or broadens. Any additional NBM detail could show whether contract coverage is becoming measurable. A miss would not identify the cause by itself; the price-volume split, inventory position and customer mix will be needed to interpret it.
