Price, not volume

The cleanest way to read this quarter is to separate what SK hynix shipped from what it charged. Revenue rose 31.9% from the second quarter. According to earnings-call figures reported by BigGo Finance and summarized separately by Seeking Alpha, DRAM bit shipments rose about 10% sequentially while average selling prices increased in the high-20% range. NAND shipments declined slightly as average selling prices increased in the mid-20% range. The same call summary reports server DDR5 shipments up more than 40%, so the mix shifted toward data centers at the same time. But the arithmetic is not close: most of a 32% sequential revenue jump, at roughly 10% more bits, is price and mix.

That is also how an operating margin reaches 79.7%, up from 76.3% in Q2 and about 72% in Q1. Memory is a commodity business in which the supplier does not set the price in any normal sense. The price is set by scarcity. Higher selling prices can lift operating margins sharply when production costs do not rise at the same rate. SK hynix's margin expansion is consistent with that dynamic, although the reported figures do not isolate how much came from pricing, HBM and server-memory mix, manufacturing efficiency or other factors.

The profit that halved on the way down the statement

Operating profit was 83.33 trillion won. Net income was 39.8 trillion won. The distance between those two numbers is the part of the release cycle most headlines skipped. Reported net non-operating expenses of 32.6 trillion won reduced pretax income to approximately 50.7 trillion won; after taxes, net income was 39.8 trillion won. The secondary earnings-call summary identifies an 11.6 trillion won net foreign-exchange loss and 22.9 trillion won in investment-asset valuation losses within the non-operating results. Those reported losses exceed the 32.6 trillion won net expense, implying offsetting items that the source record reviewed here does not fully reconcile. None of that changes the operating story. It does mean the quarter's bottom line, the figure that compounds into book value, was less than half the operating figure that made the headlines. Readers comparing SK hynix with Nvidia or Samsung on operating profit alone are comparing the line before this quarter's largest deduction.

Sold out, with the terms attached

Reuters headlined the call as SK hynix having sold out of DRAM and HBM until 2029. The company's own wording is longer and narrower. Signed long-term agreements with 14 customers cover more than 50% of planned production capacity for 2027 and 2028. That is contracted. The sold-out claim adds a second bucket: demand currently under discussion with customers, which an executive described as based on concrete purchasing plans and highly likely to come through. Contracted capacity plus likely demand equals, in the company's phrase, effectively sold out for the next three years.

The distinction matters because the two buckets can fail in different ways. A signed agreement with deposits, which the company says these include, is a commitment. A purchasing plan under discussion is an intention, and memory history is full of intentions that were revised when prices turned. The company also said customers are asking for more than twice the HBM volume it can supply today, and that it expects demand to exceed supply through 2030. Both can be true today. Neither is a guarantee about 2029, and the company's shortage forecast is a forecast, not a measurement.

A 100 trillion won round number

SK hynix plans approximately 100 trillion won in shareholder returns for 2026. Its stated components are at least 30 trillion won in dividends and at least 60 trillion won in share repurchases and cancellations, including a 40 trillion won buyback announced in August and since completed. The minimum components add to 90 trillion won, but the company describes them as floors, not a complete itemized reconciliation of the approximate 100 trillion won total. Its newly approved 20 trillion won repurchase also includes roughly 10 trillion won earmarked for employee compensation, which the company excludes from shareholder returns. The announcement therefore should not be read as 100 trillion won of entirely new commitments.
