SanDisk Corp. is transforming long-term agreements from an industry norm into a strategic moat. Recent disclosures from the company's earnings call revealed that SanDisk has signed five long-term supply agreements with customers, which are projected to account for over one-third of its NAND bit shipments in fiscal year 2027.
CEO David Goeckeler stated that this proportion has already surpassed the initial guidance of "at least one-third" and is expected to increase further with additional contracts in subsequent quarters, with the potential to "exceed 50%." This indicates a significant improvement in SanDisk's revenue visibility. The long-term contracts lock in not just shipment volumes but also establish a robust framework including minimum revenue guarantees, collateral mechanisms, and penalties for default.
The scale and structure of these contracts are substantial. According to a 10-Q filing, three contracts signed in the third quarter collectively represent approximately $42 billion in minimum contract revenue. CFO Luis Visoso indicated that while three agreements were signed in Q3, two more have been added in the current quarter, with active negotiations ongoing with additional clients. Contract durations vary, extending up to five years.
Regarding pricing, SanDisk employs a hybrid model combining fixed and floating price components. Shorter-term contracts primarily use fixed pricing, while longer-term agreements incorporate a higher proportion of floating pricing. The company explains that the floating mechanism is designed to capture upside during market price increases while offering some protection to customers during downturns.
For risk management, customers have posted collateral amounting to several billion dollars, backed by various financial instruments, covering the entire contract lifecycle. If a customer fails to meet its quarterly purchase obligations, the related financial guarantees are immediately converted into compensation for the unmet commitments.
This mechanism imposes far greater constraints than traditional supply agreements. Analysis suggests that, unlike past agreements based on mutual trust, these new contract structures feature "stronger binding force," with prepayments, minimum revenue guarantees, and financial collateral becoming a new industry standard.
Supported by multi-year contracts and locked-in demand, manufacturers like SanDisk, Seagate, and Western Digital are now more confident in committing billions to wafer fab expansion, backend capacity, and next-generation technologies such as higher-layer NAND and HAMR. The logic is clear: long-term contracts effectively secure future revenue streams upfront, reducing the uncertainty associated with large-scale capital expenditures and encouraging heavier investment in technology and capacity.
Another area of market focus is SanDisk's progress in High Bandwidth Flash (HBF). Reports indicate that SanDisk has begun engaging with partners in materials, components, and equipment to establish an HBF prototype production line ecosystem, targeting a prototype launch in the second half of the year, with Japan being a primary candidate for the production base.
CEO David Goeckeler confirmed during the earnings call that the company is actively discussing HBF deployment plans with customers and advancing full-stack development, encompassing the NAND die itself and the controller. The timeline remains consistent with previous disclosures: NAND silicon is expected to be ready by late 2026, with a complete system-level solution integrating the controller anticipated in the first half of 2027.
Furthermore, in March, Taiwanese DRAM manufacturer Nanya Technology completed a $2.5 billion private placement. Investors included SanDisk, Kioxia, SK hynix's Solidigm, and Cisco Systems. SanDisk stated that this collaboration involves an equity investment and secures priority supply rights for DRAM, which is the core strategic rationale behind the transaction.
