Samsung Electronics reported record third-quarter 2026 results on October 29: revenue of 195.3 trillion won and operating profit of 107.4 trillion won, a 55 percent operating margin, according to the earnings call transcript on Investing.com. It is the first Korean company to pass 100 trillion won in a single quarter, The Korea Times reported when Samsung pre-announced the figure on October 8. HBM4 sales more than tripled from the previous quarter.
A second line is circulating alongside the numbers: that Samsung expects long-term deals to cover up to 70 percent of its memory production through 2030. That is not what we found in the call. This post separates what Samsung said from what is being repeated.
This is a finance-flavored story, so the useful part is the second half: what it changes for the price and availability of the hardware AI builders rent and buy.

The segment figures are as summarized by Investing.com from Samsung's slides; they sum to more than the consolidated total, which likely reflects intersegment eliminations. The consolidated numbers are the ones to cite.
What drove the quarter
Almost all of the profit is memory. The chip division earned 106.5 trillion won of the 107.4 trillion won company total, while the consumer-electronics side (DX) posted a small loss. That pattern matches what we saw a day earlier at its rival: SK hynix posted an 80 percent margin on 83.33 trillion won and said memory would stay short through 2030.
Management said DRAM average selling prices rose about 20 percent and NAND prices rose in the high teens percent quarter on quarter. Shipments grew low-to-mid single digits for DRAM and mid single digits for NAND, so most of the profit growth is price, not volume. For Q4, Samsung guided DRAM bit growth of mid-to-high teens percent and NAND of mid-teens.
HBM4 is now the majority of HBM
HBM, high-bandwidth memory, is the stacked DRAM that sits next to an AI accelerator and feeds it data. Samsung said HBM4 sales more than tripled quarter on quarter and now account for roughly 60 percent of its HBM sales, and that its HBM market share reached parity with its overall DRAM share in Q3, ahead of its own second-half target.
The roadmap continues: HBM4E samples shipped in May, with mass production planned for the first half of 2027 and a volume ramp in the second half. Samsung also said its 2027 HBM supply is already sold out at an agreed target price. For context on how Samsung got here, see our earlier coverage of its HBM4 yield reaching 80 percent ahead of schedule.

Foundry and capex
Beyond memory, Samsung expects double-digit foundry revenue growth in Q4 and said 2nm project orders should more than double in 2026 versus 2025. Mass production for major 2nm customers starts in the second half of 2027, and clean-room operations have begun at Taylor, Texas, Fab 1.
Capital spending is climbing fast: 29.0 trillion won in Q3 alone, 56.9 trillion won for nine months, and 84.4 trillion won guided for the full year, up 31.7 trillion won from 2025. Much of that, 76.8 trillion won, is for the chip division.
The claim: "long-term deals may cover up to 70 percent through 2030"
Several accounts of the call compress Samsung's contract commentary into a headline that deals will cover up to 70 percent of memory production through 2030. Here is what the primary material supports.
| Claim element | What Samsung said | Verdict |
|---|---|---|
| Long-term deals are central to the strategy | 10 major accounts have signed multi-year contracts; 10 more are in talks, several near the final stage | Confirmed |
| Coverage up to 70 percent | Samsung wants multi-year contracts to cover 60 to 70 percent of mid- to long-term capacity | Confirmed as a target range, not as achieved coverage |
| Applies to all memory production | The target concerns capacity; the call also discusses HBM supply and DRAM and NAND separately | Partly: wording varies by report |
| Runs through 2030 | No 2030 date in the Q3 call; on the Q2 call Samsung described five-year agreements that are renegotiated annually and so operate on a rolling basis. Tight supply was guided through 2028 | Not found as a stated date; a five-year rolling term could be read that way |
Two things to keep apart. First, a target is not a signed percentage. Samsung described the 60 to 70 percent as what it wants contracts to cover, while naming 10 signed accounts and 10 in negotiation. Second, 2030 appears nowhere in the call material we read. The 2030 date in this week's coverage belongs to SK hynix, which said the shortage would last through 2030 and that long-term agreements with 14 major cloud providers cover over 50 percent of its 2027 and 2028 capacity.
The same 60 to 70 percent range was already on record: on Samsung's Q2 call in July, management said it expected 60 to 70 percent of planned DRAM and NAND capacity to be covered by rolling multi-year agreements with minimum-price provisions, per the Q2 call transcript on Investing.com as summarized in analyst notes. So the number is not new this quarter; the "through 2030" wrapper is an inference at most, since that call also described five-year rolling agreements.
How to check this yourself
- Read Samsung's own earnings release and presentation on its investor relations pages and look for the words "multi-year" and "long-term agreement".
- Read the Q&A section of the call, where the memory executive gives the supply outlook; here the stated horizon was 2028.
- Compare against SK hynix's disclosure, which does contain a 2030 statement, before attributing it to Samsung.
We could not read Samsung's own slides directly in this run; the figures above come from the Investing.com transcript and slides summary, cross-checked against The Korea Times and TrendForce's October 8 pre-announcement coverage. Where a figure is only in one of those, it is labeled.

Why long-term contracts matter to AI builders
Memory cycles used to be violent: prices spiked, suppliers overbuilt, prices crashed. Multi-year agreements with minimum prices and advance payments are an attempt to flatten that. For customers it means guaranteed supply at a negotiated price; for suppliers, protection against a downturn after they have spent tens of trillions of won on fabs.
For a team that buys GPUs or rents cloud capacity, the practical consequences are:
- Hyperscalers lock in memory first. If most of the capacity is contracted to a handful of large buyers, smaller buyers face the spot market and longer lead times.
- Hardware costs follow memory. HBM and server DRAM are a large part of an accelerator or server bill of materials. Samsung's roughly 20 percent DRAM price rise in one quarter is a cost that eventually shows up in server quotes. Cloud providers have already been repricing capacity, as in the AWS Capacity Blocks GPU price increase.
- Consumer devices absorb the squeeze. Samsung's own device division posted a loss, and Apple's CEO described a memory crisis in an interview this month.
- Competition is intensifying at the edges. Chinese suppliers are trying to enter HBM, though a Reuters-reported yield of 20 to 30 percent for one of them has not been independently verified; see our claimed-versus-verified post on CXMT HBM3E.
What this means for what you build or pay
Do not plan around falling compute prices in the next year. Samsung's own guidance is that tight conditions continue into 2028 and that 2027 HBM is already sold out. If you run inference at scale, that points toward efficiency work: smaller models, quantization and cache management rather than waiting for cheaper hardware. For example, DeepSeek's V4.1 Flash cut KV-cache memory precisely because memory is the constrained resource.
If you buy hardware, ask vendors about memory lead times and price protection in quotes, and expect that reserved or committed cloud capacity will be priced more favorably than on-demand capacity as supply stays tight.
What is still unknown
- Samsung's actual contracted share. The 60 to 70 percent is a goal. The call named account counts, not a percentage already signed.
- Contract length. The Q2 call described five-year agreements with annual renegotiation, so a horizon around 2030 is an inference, not a Samsung statement.
- Divisional detail. We did not have access to Samsung's own slide deck, so the split of memory between HBM, DRAM and NAND revenue is not reported here.
- Whether prices keep rising. Q4 guidance is about volume; price commentary beyond Q3 was not specific.
The wider supply-chain picture is in our AI chip supply chain roundup on TSMC, Samsung and GlobalFoundries, and the optical side of the same bottleneck is covered in Corning's Q3 results.
