KeyBanc: HBM Prices May Rise 80%-100% in Q1 2027, Long-Term Agreements Extended to 2035
nashnova research
KeyBanc analyst John Vinh forecasts HBM prices rising 80%-100% quarter-on-quarter in Q1 2027 after an Asia field trip, with supply lock-in agreements now stretching to 2035 — AI demand is rewriting the memory chip market's pricing power and cycle duration from the ground up.
HBM prices up 80%-100% — where is the squeeze coming from?
KeyBanc analyst John Vinh projects HBM prices rising 80%-100% QoQ in Q1 2027, with DRAM up 15%-20% in Q4 this year and NAND up roughly 20%.
This means → the price surge is not a single-product story. The entire memory market is being pulled higher by AI data-center demand.
The core driver is capacity allocation: suppliers plan to shift more production toward data centers, cutting PC and smartphone memory supply by 20%-30% next year.
In plain terms = same fab line, AI customers get priority — consumer electronics gets less supply and pays more.
Contracts locked through 2035 — what does that signal?
HP and Dell have extended supply agreements to 2031. Google is negotiating a deal stretching to 2035. This means → major buyers would rather lock in a decade of supply than risk a future shortage.
SK Hynix has completed long-term agreements with key customers. Micron's strategic customer contracts rose from 16 in Q2 to 26 in Q3. SanDisk has signed long-term deals with eight customers, including several big-tech firms.
Samsung said on its Q2 earnings call: "Almost all major customers are requesting long-term agreements," adding it "cannot respond to all demand."
In plain terms = memory chips are shifting from quarterly spot pricing to five- and even ten-year lock-ins — unprecedented in industry history.
Lock-ins beyond memory — is the entire AI infrastructure chain locking up?
Samsung Electro-Mechanics is finalizing a ₩700 billion MLCC (multilayer ceramic capacitor — one of the most basic components on a circuit board) long-term deal with a counterpart.
LS Cable & System has signed five-year busway (large conductor assemblies that deliver power to data-center racks) contracts with Meta, Google, and other U.S. tech firms.
This reflects a broader shift: supply lock-ins have spread from chips to capacitors, cabling, and cooling — pricing power across the entire AI infrastructure chain is tilting toward suppliers.
Who benefits most, and who got downgraded?
Vinh sees the field-trip findings as most positive for Micron — it benefits from both HBM price increases and a surge in long-term contract volume.
He also raised earnings estimates for Analog Devices, Microchip, Texas Instruments, and NXP, citing strong industrial and data-center demand. Lead times for some products have stretched to about 26 weeks; certain categories run as long as a year.
But Cirrus Logic was downgraded from Overweight to Sector Weight: roughly 80% of its revenue depends on Apple, which has cut wafer starts at TSMC — equivalent to 15-20 million fewer iPhones.
This means → memory price inflation is a tailwind for the AI chain, but a double hit for consumer-electronics-dependent companies — less supply and higher procurement costs at the same time.
Can this "super-cycle" really last until 2035?
Five years has become the standard base term for long-term agreements, with annual rolling one-year extensions. Upfront payments of 20%-25% are now industry norm.
The supply-demand imbalance keeps widening; pricing power has shifted decisively to suppliers.
In plain terms = buyers are paying 20% deposits up front and locking supply for five to ten years. That signals genuine fear of shortage — but it also means that if AI demand slows, these contracts could become a heavy inventory burden.
Whether these agreements hold through 2035 is the single most important test of this memory super-cycle's durability.
