SanDisk's long-term contracts continue to expand: Over one-third of shipments for fiscal year 2027 are already secured, with a target set at 50%.

SanDisk is upgrading long-term contracts from industry practice to a strategic moat. SanDisk recently disclosed during its earnings conference call that the company has signed five long-term supply agreements with customers, and these contracts are expected to cover more than one-third of its NAND shipments (bit) in the fiscal year 2027. CEO David Goeckeler stated that this proportion has already exceeded the previous initial guidance of "at least one-third," and with additional contracts in subsequent quarters, "it is expected to surpass 50%." This means that SanDisk’s revenue visibility is increasing significantly—not only is shipment volume locked in under long-term contracts, but also a set of strong constraints including minimum revenue guarantees, collateral mechanisms, and compensation clauses for breach of contract. Contract Scale & Structure: $42 Billion Minimum Revenue, Customers Deposit Billions as Collateral SanDisk's 10-Q filing shows that the three contracts signed in the third quarter have a total minimum contract revenue of approximately $42 billion. CFO Luis Visoso revealed that three agreements were signed in Q3, and two more so far in Q4, while the company is actively negotiating with more customers. Contract durations vary, with a maximum length of up to five years. As for pricing mechanisms, SanDisk uses a mix of fixed and floating pricing: Short-term contracts mainly use fixed pricing, while long-term contracts contain a higher proportion of floating pricing. According to the company, the floating mechanism is designed to capture upside when market prices rise, while providing some protection to customers when prices decline. In terms of risk control, customers have deposited billions of dollars in collateral, guaranteed by various financial instruments covering the entire contract cycle. If customers fail to fulfill their quarterly purchasing obligations, the related financial guarantee will immediately convert into compensation for unmet commitments. This mechanism far exceeds the binding force of traditional supply agreements. According to MoneyToday, Samsung emphasized in its earnings call last week that unlike previous supply agreements based on mutual trust, this new contract structure has "stronger binding force," with clauses such as prepayments, minimum revenue guarantees, and financial collateral becoming the new industry standard. Long-Term Contracts Drive Capital Expenditure: NAND Manufacturers Accelerate Expansion and Technology Upgrades According to Tom's Hardware analysis, supported by multi-year contracts and assured demand, SanDisk, Seagate, Western Digital, and other manufacturers are now more confident in investing billions into wafer fab expansion, backend capacity, and next-generation technologies like higher-layer NAND and HAMR. The logic is simple: long-term contracts essentially lock in revenue ahead of time, reducing uncertainty for large-scale capital expenditures, making manufacturers more willing to invest heavily in technology and capacity. HBF Progress: Prototype Line Launching This Year, Full Solution Landing in 2027 Another focus of market attention is SanDisk’s progress in the high-bandwidth flash (HBF) field. According to ETNews, SanDisk has already begun partnering with materials, components, and equipment suppliers to establish an HBF prototype production line ecosystem, targeting the launch of a prototype in the second half of this year, with Japan as a primary candidate for the production base. CEO David Goeckeler confirmed during the earnings call that the company is actively communicating deployment plans for HBF with customers and is pushing forward on full-stack development covering both the NAND die itself and controllers. On timing, Goeckeler said SanDisk maintains its previously announced schedule: NAND silicon wafers are expected to be ready by the end of 2026, and a complete system-level solution integrating controllers is expected to launch in the first half of 2027. Additionally, in March this year, Taiwanese DRAM manufacturer Nanya Technology completed a $2.5 billion private placement, with investors including SanDisk, Kioxia, SK Hynix’s Solidigm, and Cisco Systems. SanDisk stated in its earnings call that this collaboration includes equity investment and secures the company’s priority supply of DRAM, which is the core strategic logic behind the transaction.
