I wrote this to counter the potential for inconsequential cancellation of HBM orders. Obvs I used AI to structure it, but the arguments are mine and I’m lazy. Long-term HBM take-or-pay contracts are fundamentally different from traditional commodity DRAM purchasing arrangements. Several factors make default commercially and strategically unattractive. 1. Only three manufacturers: SK Hynix, Samsung and Micron are the only companies producing HBM in significant commercial quantities. A customer cannot easily find an alternative supplier. 2. Loss of future allocation: If XYZCo defaults on its contract, its supplier may reallocate production capacity to other customers. When XYZCo subsequently needs HBM, it risks finding itself at the bottom of a long waiting list, behind customers that honoured their commitments. 3. Strengthening competitors: Capacity surrendered by XYZCo could be allocated to Nvidia, AMD, Google, Amazon or another competitor. XYZCo would potentially be financing its competitors’ growth by surrendering access to a scarce strategic resource. 4. Contractual penalties: Under a genuine, enforceable take-or-pay agreement, XYZCo may remain liable for contracted purchases even if it no longer requires the memory. Default could therefore create substantial financial liabilities without eliminating the underlying cost. 5. Increasing product customisation: From HBM4 onwards, customer-specific logic base dies, packaging and integration make memory progressively less interchangeable. Abandoning a supply agreement could mean losing years of joint development, qualification and engineering investment. 6. An expanding technological moat: Each HBM generation requires increasingly sophisticated fabrication, stacking, packaging, thermal management and integration technologies. China’s inability to purchase EUV lithography equipment, together with other technological restrictions, makes the emergence of additional leading-edge suppliers particularly difficult. 7. Increasingly proprietary architectures: Future technologies such as zHBM and 3D DRAM could integrate memory much more closely with compute, incorporating customer-specific intellectual property. This would increase switching costs and deepen long-term supplier relationships, although these technologies remain under development. 8. Expanding underlying demand: AI training, inference, agentic AI, hyperscalers, neoclouds and sovereign AI infrastructure all compete for computing capacity. Customers may therefore prefer to retain HBM allocations through temporary demand slowdowns rather than risk being unable to expand subsequently. 9. No established HBM commodity cycle: Unlike conventional DRAM, AI-driven HBM demand has not yet experienced a complete boom-and-bust cycle. There is consequently no demonstrated historical basis for assuming that HBM prices and profitability must follow traditional DRAM cycles. Conclusion For XYZCo, the cost of defaulting could greatly exceed the cost of honouring its contract. Default could expose XYZCo to contractual liabilities, destroy its credibility, jeopardise future access to one of the world’s most strategically important semiconductor technologies and hand scarce production capacity to competitors. The combination of concentrated supply, increasing customisation, formidable barriers to entry and expanding AI demand gives customers powerful incentives to maintain their contractual commitments. The greatest deterrent may not be the financial penalty for default. It is the prospect of being unable to obtain HBM when the customer needs it again. This argument is strongest while HBM capacity remains scarce. It does not make defaults impossible, particularly if a customer becomes insolvent or industry-wide oversupply develops. But it provides a compelling reason why long-term HBM contracts could prove considerably more resilient than conventional memory purchasing agreements.
