The AI storage boom enters its verification phase: SK Hynix's earnings report must answer three key questions
- Core view: SK Hynix's Q3 earnings report has become a key window for testing the sustainability of AI storage demand and the strength of the HBM cycle, with the market focused on three major issues: order quality, capacity expansion pace, and the shareholder return plan.
- Key elements:
- SK Hynix and Samsung together control about 60% of global DRAM revenue and more than 80% of the HBM market share combined, making them core beneficiaries of expanding data center capital expenditure.
- KB Securities estimates that more than 70% of the two major memory makers' capacity next year has already been locked in by five-year supply agreements with large technology companies, leaving less than 30% available to other customers.
- The Kospi has fallen more than 35% from its June high, foreign investors have net sold more than $150 billion of Korean stocks this year, and the two chip stocks are down about half from their peaks.
- SK Hynix confirmed that it will announce a new shareholder return plan alongside its earnings report. Media reports put the size of a special dividend at anywhere from $12 billion to $45 billion, which the company has not confirmed.
- With delays in Oracle's data center projects and rising yields on CoreWeave bonds, the market is scrutinizing AI investment returns more closely, amid concerns that revenue will struggle to cover infrastructure costs.
- Citi expects the memory super-cycle to last as long as nine years, while Macquarie believes the current situation is a structural shortage; however, the market has already begun trading the risk of the next downturn in advance.

SK Hynix will release its third-quarter 2026 earnings report after the U.S. market closes on Tuesday. The company also confirmed that it will announce new shareholder return measures on the same day. After months of correction in AI-related assets, this earnings report will also serve as the latest window for the market to gauge the health of high-bandwidth memory (HBM) demand and the sustainability of AI infrastructure demand.
Ahead of the earnings release, shares of SK Hynix (SKHY.O) rose more than 5% at one point in the Korean market on Tuesday, while Samsung Electronics also gained more than 5%, driving the Kospi index up as much as 4.5% intraday. However, after the earlier cooling of the AI trade, the Kospi is still down more than 35% from its June high, and foreign investors have net sold more than $150 billion in Korean stocks so far this year.
The rebound came after concerns over AI financing temporarily eased. Anthropic's push toward an IPO, Meta's planned large-scale equity financing, and SpaceX's new equipment financing arrangement have revived market expectations for the sustainability of AI infrastructure investment. SK Hynix's upcoming earnings report will further test whether this recovery in risk appetite can continue.
The primary question for the market remains whether AI memory demand can continue to support current high profit levels. SK Hynix and Samsung Electronics together control about 60% of global DRAM revenue and account for more than 80% of combined revenue share in the HBM market. As demand for high-bandwidth memory from AI accelerators such as Nvidia's grows rapidly, the two companies have become major beneficiaries of the global expansion in data center capital expenditure.
Order visibility remains high for now. KB Securities analyst Jeff Kim estimates that more than 70% of the memory planned for production next year by South Korea's two major memory chipmakers is already covered by five-year supply agreements with large tech companies, leaving less than 30% available for other customers such as smartphones and PCs.
This ratio is also an important basis for the market to judge whether the current memory chip shortage is supported by real orders or relies more on continuously expanding AI capital expenditure. Billy Leung, investment strategist at Global X Management, said that memory chip prices change daily, making them one of the most real-time indicators for observing AI demand, and this week's earnings will provide important data to test the current AI investment cycle.
After the AI trade cooled, the market began to re-examine order quality
Over the past few weeks, investors have clearly become more scrutinizing of returns on AI infrastructure investment. Some Oracle data center projects have been delayed, CoreWeave bond yields have risen and its stock price has fallen, and IPO plans for some AI infrastructure companies have also been hit by market volatility. Market concerns are gradually shifting toward whether large tech companies can generate enough revenue to cover rising data center, chip, and financing costs.
This shift has already been transmitted to SK Hynix and Samsung Electronics shares, with both companies now down about half from their June highs. The热度 around highly leveraged trades tied to SK Hynix has also clearly declined.
Two Tradr ETFs launched in the U.S. only in July this year, offering two times long and short exposure to SK Hynix ADRs respectively, will be liquidated around November 12. Both funds' assets under management have shrunk more than 60% from their peaks and now total only about $1.3 million combined. The long product has fallen more than 5% since listing, while the short product has dropped 42%, even as SK Hynix ADRs rose about 5% over the same period.
Therefore, investors' focus on this earnings report is no longer limited to third-quarter revenue and profit. Whether orders have already been locked in through long-term contracts, whether major customers will continue to increase AI server investment, and whether the company will maintain a relatively restrained pace of capacity expansion at high memory chip prices are becoming more important indicators to watch.
Samsung Electronics, Japan's Kioxia, and major AI capital expenditure companies such as Alphabet (GOOGL.O), Microsoft (MSFT.O), and Amazon (AMZN.O) will also disclose earnings or the latest operating data this week. The market will cross-verify the sustainability of AI server and infrastructure demand through data from both chip suppliers and data center customers.
Scale of shareholder returns becomes another focus
In addition to HBM demand, the shareholder return plan that SK Hynix is about to announce may become another core variable in this earnings report.
SK Hynix confirmed on Monday that it is studying multiple shareholder return options and plans to announce them together with third-quarter results, but did not disclose specific details. Earlier, South Korea's Dong-A Ilbo reported that the company is considering paying a special dividend of about 16 trillion won, equivalent to about $12 billion, with funds potentially coming from gains on the sale of investments related to Japanese memory chipmaker Kioxia.
On the same day, Seoul Economic Daily cited industry sources as saying that the scale of additional shareholder returns SK Hynix plans to announce could reach as much as 60 trillion won, equivalent to about $45 billion. The figure still comes from media reports, and the company has not confirmed the final size or specific implementation method.
Dong-A Ilbo previously estimated that after selling Kioxia-related investments in the first and second quarters of this year, SK Hynix may have accumulated about 20 trillion won in investment gains and is considering returning about 80% of that to shareholders through special dividends. SK Hynix invested about 4 trillion won in Kioxia in 2018 through a consortium led by Bain Capital.
However, the company's capital relationship with Kioxia has not completely ended. SK Hynix still holds Kioxia bonds convertible into almost all voting rights of an investment vehicle, and that investment vehicle holds a 14% stake in Kioxia. Therefore, the disposal of related assets and the final return arrangement still need to be based on the company's official disclosure.
SK Hynix has already significantly increased its capital return efforts. In August, the company announced it would buy back and cancel 40 trillion won worth of treasury shares, and plans to use more than 50% of free cash flow generated from 2025 to 2027 to enhance shareholder returns.
As AI memory chips drive rapid profit growth while the stock price has fallen sharply from its highs, pressure from investors for the company to release more cash through dividends and buybacks continues to rise.
Earnings guidance will determine whether the rebound can continue
Memory chip prices remain supported by tight supply recently, and many institutions believe the industry shortage may persist. Citi analyst Peter Lee expects this memory chip super cycle could last nine years; Macquarie believes the current market is closer to a structural shortage rather than an imminent supply glut.
But the market has already begun trading the next downturn in advance, with sensitivity to new capacity and large tech companies' capital expenditure clearly increasing. Long-term supply agreements can improve order visibility, but they cannot fully eliminate cyclical risks from a slowdown in AI infrastructure investment, rising financing costs, and the concentrated release of future new capacity.
SK Hynix also suspended the planned U.S. listing of its subsidiary Solidigm last week, citing increased financial market volatility. The plan had also drawn investor and regulatory attention due to the potential impact on equity structure and valuation from a listing.
In this environment, the earnings report after Tuesday's close needs to answer three questions at once: whether HBM and DRAM orders can maintain their current strength, how the company will arrange new capacity during the supply shortage, and what scale and implementation method the new shareholder returns will ultimately take.
Tuesday's rebound in Asian chip stocks has already reflected some optimistic expectations in advance, and subsequent moves will depend more on SK Hynix's latest guidance on future demand, order coverage, and capital expenditure.
