Updated July 29, 2026
If you’re wondering why a record-breaking earnings report is being met with a shrug instead of a celebration, here’s the plain-language version: what SK Hynix actually reported, why it still missed forecasts, and what’s really driving the rough month memory stocks have had.
What did SK Hynix actually report?
SK Hynix posted a record 60.5 trillion won in operating profit for Q2 2026, up 557% from a year earlier, on revenue of 79.3 trillion won.
The South Korean chipmaker, one of Nvidia’s key suppliers of high-bandwidth memory (HBM), said sustained demand from AI infrastructure spending pushed both revenue and profit to all-time highs. Operating margin came in around 76%, an unusually high number even by the standards of this AI cycle. First-half revenue for 2026 topped 100 trillion won for the first time in the company’s history.
| Metric | Q2 2026 | Q2 2025 |
|---|---|---|
| Revenue | 79.3 trillion won (~$54.6B) | Roughly a third of this level |
| Operating profit | 60.5 trillion won (~$41.6B) | 9.2 trillion won |
| Operating margin | About 76% | Much lower |
| Analyst forecast (LSEG SmartEstimate) | 64 trillion won expected | — |
Why did the stock fall despite record profit?
SK Hynix missed forecasts because its heavier mix of specialized AI memory chips meant it benefited less from the broader price rally hitting conventional memory this quarter.
Contract prices for certain DRAM chips jumped about 52% quarter over quarter, and some NAND prices doubled. But SK Hynix leans more heavily on HBM than rivals, and HBM is typically sold under long-term contracts that recognize higher prices more slowly than the spot market does. So even with genuinely strong demand, the reported numbers can lag what’s happening on the ground, which is exactly what several analysts argue happened here.
What’s behind the rough month for memory stocks?
SK Hynix shares tumbled about 41.5% in July, their worst month since October 2008, largely on fears that China’s CXMT is closing the gap in DRAM production.
The sharpest trigger came when Chinese memory maker ChangXin Memory Technologies (CXMT) closed its Shanghai stock market debut more than 460% above its offer price, reviving worries about how fast Chinese DRAM capacity could scale. For context, CXMT held roughly 7.67% of the global DRAM market in 2025, against a combined share close to 90% for Samsung, SK Hynix, and Micron. A separate earnings estimate cut from a Korean brokerage added to the selling pressure, feeding a narrative that AI memory demand itself was weakening.
The Bull Case
- Korean customs data show memory exports rising sharply quarter over quarter, with June the strongest month on record
- HBM contracts simply recognize price gains slower than spot pricing, which can look like weak demand when it isn’t
- China’s advance so far is concentrated in commodity memory, not the specialized HBM chips powering AI accelerators
The Bear Case
- SK Hynix missed a closely watched profit forecast, which rattled confidence regardless of the underlying reason
- China’s CXMT is expanding fast and could eventually pressure pricing across more memory categories
- Some investors worry hyperscalers can’t sustain hundreds of billions in planned AI infrastructure spending indefinitely

Browse Business and FinanceWhy does SK Hynix matter so much for the AI trade?
SK Hynix is one of Nvidia’s primary suppliers of high-bandwidth memory, the specialized chips that sit alongside GPUs in AI servers.
That role has made SK Hynix a bellwether stock for the whole AI infrastructure buildout, not just a memory company. When its earnings beat or miss, the ripple runs through Micron, Samsung, and a wide swath of the semiconductor sector. That’s part of why a record quarter that technically missed a forecast could still shake the stock: expectations for anything tied to Nvidia’s supply chain have gotten extremely high.
This isn’t investment advice
Memory stocks have swung wildly this year, with moves of 10% or more in a single session becoming almost routine. If you’re considering a position in SK Hynix, Micron, or any AI-linked chipmaker, treat any single earnings report as one data point, not a green light. Consider talking to a licensed financial advisor before making decisions based on a single quarter’s numbers.
Frequently Asked Questions
How much profit did SK Hynix report for Q2 2026?
SK Hynix reported a record 60.5 trillion won in operating profit, up 557% from a year earlier, on revenue of 79.3 trillion won.
Why did SK Hynix miss earnings forecasts despite record profit?
Its heavier exposure to HBM, which is priced under longer-term contracts, meant it benefited less from a sharp rally in conventional memory prices than analysts had modeled.
Is China’s CXMT a real threat to SK Hynix?
CXMT is growing fast in commodity DRAM, but as of 2025 it held a small share of the global market compared with Samsung, SK Hynix, and Micron, and hasn’t yet challenged their position in specialized HBM chips.
Does SK Hynix’s report mean the AI memory boom is slowing down?
Not according to export data, which shows memory shipments and prices rising sharply through the quarter. The miss appears tied to accounting timing rather than a drop in underlying demand.
Bottom Line
SK Hynix just delivered its strongest quarter on record, and the demand story behind it, AI infrastructure spending by the world’s biggest tech companies, is still intact by most available measures. The stock reaction says more about sky-high expectations and a rough month for the whole memory sector than it does about a broken business. Whether that “pricing, not demand” explanation holds up will likely come down to what management says about HBM contracts and China competition in the quarters ahead.
