On July 29, SK Hynix will officially release its financial results for the second quarter of 2026. As the world’s second-largest memory chip manufacturer—and the undisputed leader in the high-bandwidth memory (HBM) market—SK Hynix stands at a critical crossroads. On one hand, the AI-driven supercycle for memory chips is pushing company profits to historic highs. On the other, its share price has dropped more than 30% from recent peaks, fueling growing concerns about the sustainability of AI investment.
At the close of trading on July 24, SK Hynix’s US-listed shares (SKHY) stood at $154.57, down 8.81% for the day. This drop was not an isolated event—since June 22, SK Hynix’s Korean shares have plunged about 40%, Samsung Electronics has fallen 29%, and the Korean KOSPI index has retreated 26% in total.
With share prices diverging sharply from fundamentals, the upcoming earnings report is viewed as a key catalyst by the market. Can HBM truly support a sustainable supercycle for AI chips? This article analyzes the situation from four perspectives: earnings expectations, the HBM market landscape, structural changes in the industry, and potential risks.
SK Hynix Q2 Results: Record Numbers Amid Market Skepticism
According to a summary by Yonhap Infomax of reports from 14 local Korean brokerages over the past month, consensus expects SK Hynix’s second-quarter revenue to reach KRW 84.1 trillion (about $60.7 billion), with operating profit hitting a record KRW 64.1 trillion (about $43.7 billion). If these forecasts are met, the numbers would mean:
- Operating profit up nearly 600% year-over-year, setting a new single-quarter record for the company;
- Single-quarter operating profit surpassing the company’s full-year 2025 operating profit record (KRW 47.2 trillion);
- Operating margin expected between 75% and 77%, marking the third consecutive quarter SK Hynix outpaces wafer foundry giant TSMC.
On a segment basis, Visible Alpha consensus estimates show SK Hynix’s Q2 DRAM business revenue at $40.4 billion, up 265% year-over-year; NAND flash revenue at $13.1 billion, up 330%. Traditional DRAM products are expected to deliver $35 billion in revenue, soaring 448% year-over-year; HBM business revenue is forecast to grow 32% to $6.1 billion.
Despite these record profit expectations, the share price has not rebounded. In addition to the sharp pullback, Samsung Electronics offers a cautionary tale: On July 7, Samsung released preliminary Q2 results—KRW 171 trillion in revenue and KRW 89.4 trillion in operating profit, an eighteen-fold year-over-year surge and a single-quarter record—yet its stock plunged over 7% the next day. The market attributes this to a "buy the rumor, sell the news" dynamic—strong fundamentals were already priced in.
J.P. Morgan analysts argue that the crash is not due to deteriorating economic or corporate earnings, but rather a combination of leveraged ETF unwinding, equity hedge fund deleveraging, and passive foreign selling. As Korea tightens rules on single-stock leveraged ETFs, the macro "deleveraging" environment is improving. Whether this is enough to reverse the share price slump, however, remains to be seen in the earnings report itself.
HBM: The Core Engine and Structural Bottleneck of the Supercycle
Analysts attribute SK Hynix’s stellar performance primarily to its leadership in the HBM market. HBM is a high-performance DRAM designed for AI accelerators such as NVIDIA GPUs, and has become an essential component for current AI infrastructure.
On the demand side, UBS’s July memory chip report forecasts HBM demand will grow 90% year-over-year in 2026, reaching about 33.1 billion Gb; in 2027, demand is expected to rise another 77% to about 58.7 billion Gb. The market considers 2026 the inaugural year of the "HBM supercycle," with global HBM3E and HBM4 capacity locked in long-term by NVIDIA, AMD, and cloud providers, resulting in a supply gap of 50% to 60%.
On the supply side, HBM production cycles last four to six months, with initially low yields, and each chip consumes about three times the wafer capacity of standard DDR5 DRAM. SK Hynix CEO Kwak Noh-Jung predicts that, to meet rapidly growing AI demand, memory chip supply constraints will persist beyond 2030.
In terms of market share, SK Hynix controlled about 56% to 58% of the HBM market in Q1 2026, with Samsung Electronics and Micron Technology each holding roughly 21% to 22%. This leadership is largely due to deep collaboration with NVIDIA—the largest buyer of HBM chips—whose certification schedule directly determines suppliers’ shipment pace. KB Securities notes that SK Hynix’s first-mover advantage in HBM3E puts it 12 to 18 months ahead of Samsung in NVIDIA’s certification process.
However, this lead is not unassailable. Samsung began commercial shipments of HBM4 this year and has sent HBM4E samples to global clients; SK Hynix’s HBM4 has entered mass production, and in June, it also sent HBM4E samples to major customers. Competition between the two companies for next-generation products is intensifying. Meanwhile, Micron Technology is actively expanding production, though its smaller scale limits its ability to challenge the Korean giants on pricing.
For investors, the core question is the sustainability of profit margins. SK Hynix’s 75% to 77% operating margin—exceptional for a memory chip manufacturer—reflects HBM’s significant premium over traditional DRAM. KB Securities warns that Samsung’s aggressive HBM roadmap and Micron’s capacity expansion could compress margins by 5 to 10 percentage points over the next four quarters.
Structural Shift: From Consumer Electronics Cycles to AI Infrastructure Cycles
This memory chip supercycle differs fundamentally from previous cycles—the demand driver is shifting from consumer electronics to AI infrastructure investment.
Kim Dong-won, head of KB Securities’ research department, points out that as HBM capacity expands, the supply capability for general-purpose memory will remain constrained. At the same time, the share of long-term agreements is rising, and sales to global tech companies and AI data centers are expected to reach 70%.
The significance of this structural shift lies in improved profit quality. B2B sales accounted for only 30% in 2017, but are projected to reach 70% by 2027. Analysts believe that the sharp increase in B2B sales to large tech companies and AI data centers will markedly enhance profit quality and stability. The predictability of income from long-term supply agreements should reduce earnings volatility and support higher valuation multiples.
On the financial side, SK Hynix returned to a net cash position (cash assets exceeding borrowings) in Q3 2025, for the first time since 2019. By the end of Q1 2026, net cash had grown to KRW 35 trillion, and the market expects further expansion in Q2.
However, structural shifts also introduce new uncertainties. Earlier this month, the Bank for International Settlements warned in its annual economic report that stage-specific shortages across the AI supply chain are amplifying the risk of overinvestment. Companies are locking in future capacity through long-term contracts, but this exposes them to greater risk if demand falls short of expectations.
Three Major Risk Factors
First, the "double-edged sword" effect of long-term agreements. The surge in AI-driven demand has led to a wave of large-scale long-term supply contracts. Yet the market is questioning: In times of industry strength, these contracts seem unbreakable, but when demand reverses or the market weakens, how much certainty and binding force remains? If major cloud providers cut back on AI infrastructure spending due to lower-than-expected returns, execution of these contracts could be challenged.
Second, the race for capacity expansion. Samsung Electronics, SK Hynix, and Micron—the three memory giants—are leading the push to expand capacity. Samsung plans to invest more than KRW 110 trillion in equipment and R&D in 2026; the Korean government has announced a total industry investment of KRW 392 trillion in the Chungcheong region, supporting Samsung and SK Hynix in building HBM wafer fabs and packaging facilities. Despite the current supply gap of 50% to 60%, large-scale capacity expansion often carries the risk of a cycle peak—when supply is released en masse and demand growth slows at the margin, pricing structures may come under pressure.
Third, can the gap between valuation and fundamentals narrow? SK Hynix’s share price has dropped more than 30% from its peak, while profits continue to set records. This disconnect could be an overreaction—a "mispricing"—or it could reflect the market’s forward-looking pricing of slower future profit growth. The July 29 earnings report and management’s guidance for the second half will be key to assessing whether this valuation discount has room to recover.
Conclusion
SK Hynix’s upcoming Q2 earnings report will likely deliver record-breaking numbers—KRW 84 trillion in revenue, KRW 64 trillion in operating profit, and operating margins above 75%. By any measure, these are rare levels of profitability in manufacturing.
But the market is no longer satisfied with "record-breaking" alone. With share prices well off their highs, investors are looking for confirmation on three fronts: whether HBM’s pricing power can withstand competitive pressure; whether capital expenditure cycles for AI infrastructure show signs of slowing; and whether this earnings report can serve as the starting point for a valuation recovery, rather than confirmation of a cycle peak.
The memory chip industry is undergoing a structural transformation driven by AI—from consumer electronics cycles to AI infrastructure cycles. The long-term direction is clear, but the volatility and uncertainty along the way are just as real. For investors watching this sector, the July 29 earnings report is not just SK Hynix’s "report card"—it’s a critical stress test for the entire AI chip supercycle.
