SK Hynix Q3 2026 Profit Hits Record as AI Memory Demand Doubles Supply

SK Hynix reported a record quarterly operating profit of 83.3 trillion won for the three months to September 30, up 632 percent from 11.4 trillion won a year earlier, and said it is sold out of high-bandwidth memory and DRAM chips until 2029. The South Korean company, the leading supplier of the HBM modules inside Nvidia's AI accelerators, announced the results on Wednesday, October 28. The 83.3 trillion won figure beat the 76.7 trillion won SmartEstimate compiled by LSEG and the 77.5 trillion won consensus tracked by Bloomberg.

Shares of the company jumped nearly 8 percent in Seoul trading to 1,446,000 won on the announcement, and the print lifted the broader AI trade across Asian markets during a session that also had investors positioning for a Federal Reserve decision. For a company whose products sit at the physical choke point of the AI buildout, the reaction says as much about the market's fears as about the quarter. Investors had spent recent weeks arguing about whether spending on AI data centers can keep climbing; SK Hynix's own order book is one of the few places that fear gets a direct, verifiable answer.

The memory dynamics run deeper than the headlines. SK Hynix said it is sold out of both HBM and DRAM through 2029, which means the scarcity is not limited to the specialized AI chips that pack high-bandwidth stacks onto accelerators. DRAM is the commodity memory inside everything from servers to phones and laptops, and the company acknowledged that higher prices will push up costs for personal computers and handsets as suppliers allocate capacity to the more profitable AI products. That is the familiar memory cycle in compressed form, with AI demand handing a single segment the power to move the whole product line.

The shareholder payout is unusually generous for a company that says it needs to reinvest to expand. SK Hynix outlined about 100 trillion won, close to 75 billion dollars at the 1,326 won per dollar rate Reuters used Wednesday, in total distributions for the year, split between cash dividends of more than 30 trillion won and share repurchases and cancellations of more than 60 trillion won, the latter figure including the 40 trillion won program announced in August and completed last week. For the third quarter it declared a cash dividend of 14 trillion won, or 20,000 won a share, including a 10,000 won special dividend tied to the Kioxia gain, alongside a fresh 20 trillion won repurchase. It also committed to returning 50 percent or more of free cash flow to shareholders going forward.

Management framed the payout and its investment plans as complementary rather than competing for the same capital. It said it will increase capital expenditure substantially next year from this year's level, focused on equipment for advanced chipmaking processes and on infrastructure in South Korea and overseas. The combination, more cash back to shareholders at the same time as a step-up in investment, signals confidence that the demand shock is durable enough to fund both.

Revenue jumped 328 percent to a record 104.6 trillion won for the quarter, while net income climbed 216 percent to 39.78 trillion won, the company said in its 3Q26 results statement. The gains trace directly to the AI buildout rather than to a rebound in consumer gadgets. Management said on the call that HBM demand is roughly double what it can supply and that a chip shortage looks likely to continue through 2030.

The visibility behind that claim comes from signed customers. SK Hynix said it has long-term supply agreements with 14 major buyers and that the volumes already contracted correspond to more than half of its 2027 and 2028 production capacity. A model that management said typically runs about five years is now being extended with several customers, a rare degree of booking visibility for a memory maker, a sector that has historically swung between boom and bust.

The print is the strongest counter yet to the worry that the AI capex cycle is peaking. Microsoft and Alphabet report their own numbers on Wednesday, and Amazon follows on Thursday, so SK Hynix's sold-out HBM is a supply-side datapoint landing in the middle of the most closely watched earnings week of the season. When the maker of the most constrained component says it cannot make enough through 2030, the bear case has to lean on the buyers rather than on the upstream sellers.

The bears still have a case. Memory is cyclical, and the business is heavily exposed to a narrow set of AI customers, with Nvidia the most important. A sharp deceleration in hyperscaler orders would hit HBM pricing harder than any other chip segment precisely because the current surge is concentrated. The record cash return also commits the company to large payouts at a moment when it says it will raise capital expenditure substantially next year to add advanced capacity in South Korea and overseas.

Analysts treated the number as clearing out the skepticism. The results have eased many of the market's concerns, with earnings coming in ahead of expectations, said Ryu Young-ho, a senior analyst at NH Investment & Securities. Given that the fourth quarter is traditionally stronger, operating profit could approach 100 trillion won.

What to watch next. Samsung reports its quarterly results later this week, giving a second read on the HBM and memory cycle. On the demand side, TSMC publishes October monthly revenue on about November 10, the cleanest single gauge of advanced chip demand, and the megacap earnings that begin tonight will show whether the buyers behind this surge are still committing capital at the same pace. SK Hynix's guidance says the constraint is real. The reporting season that starts now tests whether the others agree.
