Shares of SK Hynix surged as much as 9.4% in early Seoul trading on October 28 after the world's second-largest memory chipmaker reported its strongest quarter ever and unveiled a shareholder-return plan so large it reframes how investors should value the stock. SK Hynix Posts the Biggest Quarter in Memory-Chip History — but With Shares Up 16%, Is the AI Boom Already Priced In?
Shares surged as much as 16% after SK Hynix reported what no memory chipmaker has ever delivered: record third-quarter revenue topping ₩104.6 trillion and operating profit reaching ₩83.3 trillion , fueled by insatiable demand for chips that power artificial-intelligence data centers. The company simultaneously unveiled a plan to return about $75 billion to shareholders this year — a sum that instantly reframes the investment case.
An 80% Profit Margin That Defies the Chip Industry's Brutal History
An 80% operating margin is extraordinary for a memory manufacturer, an industry historically characterized by fierce competition and pronounced cycles.
Revenue rose 328% from a year earlier , while operating profit increased 632% year over year . The numbers beat analyst expectations: Wall Street had projected ₩76.7 trillion in operating profit and ₩98.3 trillion in revenue . The blowout tells investors that AI-memory pricing power remains intact — for now.
A $75 Billion Cash Return Signals Management Thinks Shares Are Cheap
For fiscal 2026, SK Hynix will pursue shareholder returns totaling approximately ₩100 trillion, comprising cash dividends of ₩30 trillion or more and share repurchases and cancellations of ₩60 trillion or more.
That equals roughly 9.5% of the company's current market capitalization — a staggering yield that signals management believes the stock is undervalued relative to its cash-generation power. SK Hynix held net cash of $74.4 billion at quarter-end , giving it ample firepower to follow through.
"Sold Out Through 2029" Is the Boldest Demand Claim in Semiconductors
SK Hynix said its DRAM and high-bandwidth memory supply volumes for the next three years through 2029 are effectively sold out.
The company has signed long-term agreements with 14 major customers , and customers' requested supply exceeds what SK Hynix can actually produce by more than twofold . If those contracts hold, earnings visibility stretches years — a rarity in a notoriously boom-bust business. The risk: long-term agreements lock in volume but not always price, and any AI spending pullback could test those commitments.
The Open Question: Valuation Versus Gravity
Analysts expect annual operating profit to surpass ₩260 trillion this year and reach ₩400 trillion next year. At $1,145, investors are betting the AI-memory supercycle has years to run. The counterargument is simpler: cycles always turn, and paying peak prices for peak earnings has historically punished chipmaker shareholders.
