SK Hynix Q3 Profit Jumps 7x to 83tn Won on HBM Demand

SK Hynix reported third-quarter operating profit of around 83 trillion won on 27 October 2026, roughly seven times the year-earlier level, at an operating margin of around 80%. The company also unveiled a 100 trillion won shareholder payout plan. The result was driven largely by high-bandwidth memory, or HBM, and by the way HBM production absorbs wafer capacity that would otherwise make ordinary DRAM, lifting prices across the entire memory market rather than only at the premium end.

Context — why HBM now sets memory prices

The comparable the company itself supplies is stark. Operating profit at around 83 trillion won is roughly seven times the level of a year earlier, and the margin near 80% is the kind of figure memory makers have not printed in ordinary parts of the cycle. The report attributes the surge to DRAM and NAND pricing in its headline figures, but names HBM as the product behind much of it.

What changed is the demand mix. AI accelerators need memory bandwidth more than they need raw compute, because training and running large models means moving enormous volumes of data in and out of memory. Without enough bandwidth, an expensive processor sits idle. Every leading AI accelerator, including Nvidia's GPUs, is packaged with HBM for that reason, which turns a niche memory type into one of the most valuable components in an AI server.

The mechanism that transmits HBM demand into the wider market is capacity. Industry estimates commonly put HBM's wafer consumption at around three times that of standard DRAM per bit, because the dies are larger, the stacking process is complex, and some output is lost along the way. As manufacturers move lines toward HBM, less capacity remains for the conventional DRAM used in PCs, phones and servers.

That squeeze shows up in price. SK Hynix reported DRAM selling prices up by a high-20% rate in a single quarter. For a component that goes into nearly every computing device, a move of that size in one quarter is what turns a product-level story into a sector-level one.

Data — what the numbers show

The headline figures are operating profit of around 83 trillion won, roughly seven times the prior-year level, an operating margin of around 80%, and a 100 trillion won shareholder payout plan. DRAM selling prices rose by a high-20% rate in the quarter.

On supply, the market is a three-way oligopoly. Counterpoint Research puts SK Hynix at around 50% of HBM revenue in the second quarter of 2026, down from around 64% a year earlier. Samsung rose to around 33% as it caught up on the previous generation, HBM3E. Micron held around 18%.

HBM revenue share	Q2 2025	Q2 2026
SK Hynix	~64%	~50%
Samsung	—	~33%
Micron	—	~18%

The share shift is the most important number in the dataset. SK Hynix lost roughly 14 percentage points of HBM revenue share in a year while its absolute profit still multiplied sevenfold, which tells you the market itself grew faster than any single supplier's position eroded. Samsung's gain to around 33% is the first hard evidence that the follower has closed the gap on HBM3E.

The next generation is already in production. HBM4 doubles the width of the connection to the processor and is being built into Nvidia's new Vera Rubin platform. Nvidia chief executive Jensen Huang said in June that all three suppliers are in production for Vera Rubin, with the first systems due to ship in the third quarter. Analysts estimate SK Hynix supplies the majority of that HBM4 volume, though Nvidia has not disclosed any split.

Analysis — what it means for markets and tickers

The second-order effects run in two directions. Memory makers are the obvious beneficiaries. SK Hynix, Samsung Electronics and Micron all sell into the same tight market, and the wafer-capacity mechanism means a strong HBM book supports pricing on their commodity DRAM lines too. That is why a product that sits inside AI servers can lift earnings on chips that go into laptops.

The pressure lands on buyers. PC, phone and server makers that purchase memory face higher input costs, and the report notes this weighs on their margins. Those companies cannot easily pass through a high-20% quarterly DRAM price move without affecting unit economics, and the ones with the least pricing power absorb it first.

There is a market-structure angle specific to Korea. The concentration of HBM supply makes the Kospi and the wider Korean market unusually sensitive to AI spending, and changes in HBM share between SK Hynix and Samsung can move both stocks sharply. A 14-point share shift in a year is exactly the kind of move that reprices two of the largest listings in Seoul.

The counter-argument is the cycle itself. Memory has always been cyclical, and the report flags that some forecasters warn HBM prices could soften once competition and new capacity catch up with demand. The three-way race in HBM4 is the mechanism: if all three suppliers ramp simultaneously into a market that stops growing as fast, the pricing power that produced an 80% margin fades, as it has in past memory cycles. Positioning reflects that tension. Investors are long the earnings momentum and the payout plan, while the share-loss data and the HBM4 ramp are the reasons some are watching for the turn.

Outlook — what to watch next

Three catalysts matter. First, HBM4 volumes and pricing as Vera Rubin systems ship following the third-quarter start Nvidia guided to. Second, the pace at which Samsung and Micron gain ground on SK Hynix, measured in the same Counterpoint share series that showed the drop from around 64% to around 50%. Third, whether AI spending keeps growing fast enough to absorb new supply.

On levels, the report gives no specific price targets or support zones for SK Hynix, Samsung or Micron, so the cleanest read is through the share series and the DRAM price trend rather than chart levels. If DRAM selling prices continue to rise at a high-20% quarterly rate, the earnings support holds. If that rate decelerates while HBM4 capacity comes online, the margin compression argument gains evidence.

Frequently Asked Questions

What is HBM and why does it matter for chip prices?

HBM is a type of DRAM that stacks a dozen or more thin memory dies vertically and places the stack right beside the processor, connected by thousands of tiny vertical links. That delivers far more bandwidth per second at lower power. It matters for prices because making it uses roughly three times the wafer capacity per bit of standard DRAM, so shifting lines to HBM leaves less capacity for ordinary memory.

Why did SK Hynix's HBM market share fall while profits rose?

Counterpoint put SK Hynix at around 50% of HBM revenue in the second quarter of 2026, down from around 64% a year earlier, as Samsung rose to around 33% on HBM3E. Profits still multiplied because the overall HBM market grew faster than SK Hynix's slice of it shrank. Losing share in a rapidly expanding market can still mean selling far more units than the year before.

What does the 100tn won payout plan mean for shareholders?

SK Hynix unveiled a 100 trillion won shareholder payout plan alongside the results. The report does not disclose the terms, timing or structure of the payout, so the split between dividends and buybacks is not public. What the plan signals is that management sees the current cash generation as durable enough to return capital rather than reinvest all of it in capacity.

Bottom Line

HBM's wafer-hungry economics are lifting all memory prices, but SK Hynix's falling share shows the cycle's turn risk is already visible.
