Samsung Pushes Long-Term Memory Supply Agreements as AI Demand Spreads from HBM to DDR5 and NAND
Claire Weston
Samsung Electronics is making long-term memory supply contracts a strategic priority for H2, as data-center clients extend procurement demand from HBM across DDR5, NAND, and enterprise SSDs — the memory industry's competitive axis is shifting from 'who can build the most' to 'who can secure supply first.'
Why are clients suddenly locking in three-to-five-year deals?
Data-center buyers have shifted focus from pressing prices down to securing volume years in advance. All three major suppliers — Samsung, SK Hynix, and Micron — face surging demand for long-term agreements.
This means → clients believe memory will stay tight and would rather lock in prices now than gamble on the spot market later.
UBS notes these contracts typically run about five years, structured as "three-year fixed price + two-year renewal option" or "two-year fixed + three-year option."
In plain terms = this isn't a one-off purchase — it's closer to a power-purchase agreement, locking in both volume and price for years ahead.
Is this cycle still just an HBM story?
No. DDR5, LPDDR, NAND flash, and enterprise SSDs are all seeing clear demand growth as AI models drive up data storage, retrieval, and transfer needs across the board.
South Korea's early-June export data tells the story: daily average DRAM exports surged 308% YoY to $490 million; NAND rose 151%; MCP and SSDs climbed 81% and 91% respectively.
Prices are moving too: MCP prices jumped 72.5% MoM and NAND prices rose 24.3% MoM in the first ten days of June.
This reflects a broader spillover — HBM was the starting point, but the range of products under strain is widening fast.
How much memory capacity could long-term contracts lock up?
Industry estimates suggest 20%–30% of total DRAM volume and roughly 20% of NAND volume could shift to long-term contracts next year.
Server DDR5 is already well ahead: about 60%–70% of shipments are currently covered by such arrangements.
This means → the tradeable pool in the spot market will shrink materially, and downstream players without long-term deals may face higher procurement costs and greater supply uncertainty.
What positions are Samsung and SK Hynix each racing to secure?
SK Hynix leads in HBM; Samsung is narrowing the gap with HBM4 and next-generation products.
Samsung confirmed on its Q1 earnings call that it has signed partial long-term agreements with key clients including Nvidia, AMD, and Google.
On capacity timelines, SK Hynix plans to triple wafer capacity by 2034, with its Y1 fab expected to bring new capacity online around 2027; Samsung's P5L fab is projected to start production around 2028.
In plain terms = both are racing — but the race is not about who builds a factory first; it's about who allocates limited capacity to the most important customers first.
Why might this cycle avoid the classic 'overbuild → crash' pattern?
The traditional up-cycle path: prices rise → producers expand aggressively → supply gluts → prices collapse.
The key difference this time: clients are proactively locking in volume before prices rise further, rather than waiting until peak pricing triggers aggressive capacity additions.
This means → both sides of the supply chain are trying to avoid the traditional boom-bust loop, and the long-term contract mechanism itself acts as a shock absorber.
But oversupply risk has not vanished — overbuilding during the up-cycle could still leave suppliers facing price declines and inventory buildup if demand retreats.
