The Bonus That Broke Samsung’s Talent Bank: How SK Hynix Turned a Strike and a Funding Frenzy Into a $6.8 Billion AI Fab

Profit-taking after 52-week high masks HBM4 surge: customers fund production lines, record Q1 profits, Samsung talent exodus, and yield gap. UBS raises target.

An eight percent slide in SK Hynix’s shares on Friday looked brutal at first glance — a 1,819,000 won close that clipped 168% of year-to-date gains. But the selloff was pure profit-taking after the stock had minted a fresh 52-week high just days earlier. The long-term narrative, supported by a 72% operating margin in the first quarter and a client list desperate for capacity, remains very much intact.

No single metric captures that desperation better than the way some customers are trying to buy their way to the front of the line. Sources familiar with the matter say several big tech names have offered to finance entire production lines at SK Hynix — including the hundreds-of-millions-of-dollars EUV lithography machines from ASML — just to secure supply of next-generation HBM4 memory. The South Korean giant is weighing the proposals carefully, wary of becoming too dependent on any single buyer.

That appetite for chips is driving a construction push that will test even SK Hynix’s deep pockets. Management has earmarked roughly $6.8 billion for a new fabrication plant in the Yongin semiconductor cluster, with the first phase due to wrap up by the end of 2027. The facility will provide the clean-room space needed for HBM4 and the memory generations that follow.

But money isn’t the only thing flowing into the company. Talent is, too, and at the expense of its biggest rival. SK Hynix’s uncapped bonus system — ten percent of annual operating profit distributed to employees since September last year — has turned into a powerful recruitment weapon. In February 2026, workers received a profit-sharing payout equal to 2,964% of their monthly base salary. For someone on an annual salary of 100 million won, that meant an extra 148 million won. According to trade union chief Choi Seung-ho, about 200 Samsung Electronics engineers jumped ship to SK Hynix in the four months through February alone.

The gap in manufacturing yields adds another layer of tension. Samsung’s HBM4 output is running below 60%, while SK Hynix’s 1c DRAM process already hits 80%. Now a threatened 18-day strike at Samsung starting May 21 could widen that gap further. A prolonged walkout would push orders toward SK Hynix, especially since the AI memory market is already sold out and a customer switch in semiconductors takes months of process validation and certification. Once clients move, they tend to stay.

Financially, SK Hynix has the firepower to absorb the rising costs. First-quarter 2026 revenue hit 52.6 trillion won, with operating profit climbing to 37.6 trillion won. Analysts expect second-quarter revenue to jump to 78 trillion won. Capital expenditure and research spending are budgeted at 50 trillion won for the full year, up from 36.6 trillion won in 2025. UBS recently lifted its price target to 1.7 million won, raising 2026 and 2027 earnings forecasts by 22% and 29% respectively, citing a memory cycle not seen in nearly three decades.

Investors get two key dates this month. The stock goes ex-dividend on May 28 with a payout of 375 won per share. And on May 21, Samsung workers will decide whether to walk out — a decision that could accelerate the talent and order flow already tilting SK Hynix’s way.
