SK Hynix Enters 'Zero Supply' Era: Margins Surge Above 70% as Rival Faces Historic Walkout

SK Hynix posts record 72% operating margin as analysts double targets, citing structural shift from cyclical memory to AI-driven growth amid tightest supply in 15 years.

The semiconductor landscape is undergoing a tectonic shift, and SK Hynix finds itself at the epicenter. Analysts who once treated memory makers as cyclical commodities are now rewriting their valuations, arguing that the South Korean giant has permanently broken free from that boom-bust mold. The catalyst? A supply crunch so severe that Goldman Sachs warns of the tightest market in 15 years by 2026, paired with a blockbuster earnings report that has sent operating margins into uncharted territory.

Nomura Securities doubled its price target over the weekend to 4 million won, implying more than 100% upside from current levels. The call is grounded in a thesis that SK Hynix is transforming from a volatile memory manufacturer into a structural growth engine. KB Securities followed with a target of 3 million won, coining the phrase "era of zero supply" — no meaningful new production lines are expected to come online before 2027. Long-term contracts, increasingly resembling those of a pure-play foundry, are locking in revenue streams and smoothing out cycles.

The numbers back up the optimism. First-quarter revenue nearly tripled to 52.58 trillion won, while operating profit hit 37.61 trillion won, translating into a historic margin of 72%. That figure is poised to rise further: management now expects a full-year operating margin of 78%, an industry-leading level. Research and development spending surged nearly 70% year-on-year, a significant chunk of it going into poaching specialized hardware engineers in an escalating talent war.

Yet the share price tells a more volatile story. The stock slipped nearly 8% on Friday to 1,819,000 won, caught in a wave of profit-taking as the broader U.S. semiconductor sector softened. The pullback looks minor, however, against a year-to-date gain of roughly 169%. The market capitalisation is now flirting with the 1 quadrillion won mark, and the stock remains well above its 50-day moving average of around 1,160,000 won — a key technical support that bulls will watch closely.

Adding fuel to the fire is a looming strike at archrival Samsung Electronics. From 21 May, some 50,000 workers plan to walk out for 18 days, threatening production at the world’s largest memory maker. A prolonged dispute could shift additional orders for AI accelerators toward SK Hynix, accelerating its already dominant position in high-bandwidth memory. The company confirmed that demand for its current HBM capacity already exceeds supply for the next three years, and samples of the next-generation HBM4E memory are scheduled to leave the fab in the second half, with mass production set for 2026.

Shareholders have a near-term date on their calendar: 28 May, when the stock goes ex-dividend for the current quarter. Management recently confirmed a payout of 750 won per share, made possible by a cash-rich balance sheet. Beyond that, the market is waiting for details on the HBM4 roadmap, which management has hinted will be unveiled soon.

For now, the narrative is overwhelmingly bullish — a rare alignment of structural supply constraints, a rival in turmoil, and pricing power that rivals haven't seen in a generation. The question is whether profit-takers will let the rally resume before the next catalyst arrives.
