SK Hynix Locks Up 2026 HBM Capacity and Snares 200 Samsung Engineers in AI Memory Blitz

SK Hynix sold out all 2026 HBM capacity, poached 200 Samsung engineers in four months, and saw stock surge 169%. Nomura sees 120% upside as AI memory demand dwarfs supply growth.

The Korean memory giant is fighting on two fronts and winning on both. SK Hynix has already sold every sliver of its high-bandwidth memory output for 2026, while simultaneously poaching roughly 200 engineers from home-town rival Samsung Electronics in the past four months alone. The result: a share price that has surged nearly 169% since the start of the year and an analyst community scrambling to scrap its old cyclical narratives.

Nomura Securities now sees the stock more than doubling from current levels. The brokerage slapped a price target of four million Won on the shares, implying upside of about 120%, and reclassified SK Hynix from a cyclical chip producer to a structural beneficiary of the artificial-intelligence build-out. The stock closed Friday at 1.819.000 Won after taking a breather from a recent record high.

A supply dynamic that gives the seller the upper hand

Demand for specialized AI memory components is forecast to increase a thousandfold over the next five years, according to Nomura, while global supply is expanding at an estimated 30% annually. That widening gap has handed SK Hynix enormous pricing power. The company is increasingly locking hyperscaler customers into three- to five-year supply agreements that often require upfront payments and co-investment in development costs.

The tightness is so extreme that anyone hoping to place a fresh order for 2026 HBM inventory is simply out of luck. That scarcity is forcing the Street to rethink the company’s earnings trajectory. KB Securities projects operating profit of 277 trillion Won for the current year — a figure that implies an operating margin of 78.1%. Standard memory chip price increases are adding further fuel to the fire.

A bonus system that keeps on giving

SK Hynix’s talent raid on Samsung is no accident. Since September last year, the company has been channeling 10% of its annual operating profit directly into an uncapped performance bonus pool. In February 2026, employees received a payout equivalent to 2.964% of their monthly base salary — for someone earning 100 million Won a year, that meant an extra 148 million Won in cash. Union chief Choi Seung-ho confirmed that around 200 Samsung engineers had jumped ship in the four months through early spring.

The mechanism is self-reinforcing. Analysts forecast 2026 operating profit of roughly 250 trillion Won, producing a bonus pool shared among about 35,000 staff. On average, each employee could pocket around 700 million Won. That kind of compensation turns SK Hynix into a magnet for talent, especially when Samsung is wrestling with a strike threat.

Samsung’s labor pain, SK Hynix’s gain

The mood at Samsung’s chip plants is tense. After state-mediated talks collapsed, the largest union is threatening an 18-day walkout starting May 21. That would disrupt memory production just as the market is straining against capacity. Even without a strike, Samsung is underperforming: its HBM4 yield sits below 60%, while SK Hynix already hits 80% on its 1c DRAM process. Any delivery delays could push hyperscaler customers such as Microsoft, Google, and Amazon even faster toward the rival’s already-busy order books. A change of supplier in semiconductors is never quick — validation and certification take months — so the first mover advantage is huge.

Record spending and a clear roadmap

SK Hynix is pouring money into the next phase. Research and development spending jumped to 2.55 trillion Won in the first quarter alone, while total capital expenditure and R&D for the full year is budgeted at 50 trillion Won, up from 36.6 trillion Won last year. First samples of HBM4E memory are due in the second half of 2026, with mass production scheduled for 2027.

The financial results are already reflecting the momentum. In the first quarter of 2026, sales hit 52.6 trillion Won and operating profit reached 37.6 trillion Won, translating into a 72% margin. The consensus estimate for the second quarter stands at 78 trillion Won in revenue. UBS raised its price target to 1.7 million Won in early May and lifted profit forecasts for 2026 and 2027 by 22% and 29% respectively, calling the memory cycle the strongest in almost three decades.

Valuation still offers room — and Nvidia is the next catalyst

Despite the rally, SK Hynix trades at just six times expected earnings. For context, global foundry heavyweight TSMC changes hands at roughly 20 times earnings. Analysts expect the Korean stock’s multiple to expand over time as investors increasingly view it as a structural AI play rather than a cyclical memory name.

The immediate test comes Wednesday, May 20, when Nvidia reports quarterly results. As the primary supplier of memory for Nvidia’s AI accelerators, SK Hynix’s short-term fortunes are closely tied to the Santa Clara giant’s outlook. Meanwhile, the Samsung strike decision lands on May 21, and the ex-dividend date for SK Hynix shares — a payout of 375 Won per share — falls on May 28. Three milestones in eight days will tell investors whether the stock’s breathtaking run can continue.
