SK hynix's contracted volumes make revenue more dependable than margins. LTAs cover over half of 2027-28 capacity, but not all demand through 2029 is signed, and prices still move within agreed ranges. Big customers' 2027 HBM volume and pricing are settled; HBM4 yields are ahead of plan. Server DDR5 shipments rose over 40% quarter on quarter, though most of the earnings beat came from pricing. Management expects the HBM profit premium over regular DRAM to narrow next year. x.com
SK hynix's wider customer commitments challenge the idea its memory boom ends in 2027-28. LTAs now span 14 customers, up from about 10 in July, and cover more than half of total 2027-28 capacity, not just HBM. Q3 margin rose to 80% from 76%. Shares fell 48% since July 1 as tracked DDR5 spot rose 31% and Q3/Q4 revenue forecasts slipped just 5%/2%. Contracted volume does not lock in margin: prices move with the market within agreed ranges, and investment is set to rise significantly next year. x.com x.com
SK hynix's enforceable long-term supply commitments add visibility to memory profits. It says DRAM and HBM volumes through 2029 are effectively sold out, with agreements covering over half of 2027-28 capacity while retaining pricing flexibility. Operating profit beat expectations at $62.8B versus about $58B, and SK hynix announced $75B in 2026 shareholder returns. It expects the memory shortage to persist through 2030. x.com
SK hynix's stronger pricing and contracted demand support the still-favored memory duration trade. DRAM and HBM capacity is sold out through 2029, and a supply-demand imbalance is expected through 2030. More than half of 2027-28 capacity is under long-term agreements, with agreed 2027 HBM prices significantly higher year on year. Guangfa HK expects fund flows and bearish sentiment to improve after earnings. x.com
Memory makers' long-term agreements cannot protect pricing when buyers regain leverage. The market underestimates downside even before a price collapse; SK hynix's agreements price within market-linked ranges, per @jukan05. The agreements will be ripped apart when the market turns to buyers, at the latest when China ramps. SK hynix, Samsung, Micron, SanDisk and Kioxia are exposed. x.com
SK hynix stands to benefit from higher HBM prices as supply remains constrained. Needham expects HBM price increases next year and tight memory supply through 2030; SK hynix has finalized 2027 HBM prices and volumes with major customers. SK hynix also plans roughly KRW100 trillion in FY2026 shareholder returns, including at least KRW30 trillion in dividends and KRW60 trillion in share acquisitions and cancellations. x.com x.com
SK hynix's five-year agreements with 14 major customers cover more than half its 2027-28 capacity, giving its memory earnings unusually long visibility. DRAM prices rose 28% and NAND 25% in the quarter, while operating profit reached 62.8 billion against 58.5 billion expected; Q4 DRAM shipments are guided up 25% from Q3. Those commitments support the view that demand is not peaking yet. Overweight, $400 target. x.com
SK hynix and other Korean memory makers' aggressive price hikes invite customers to optimize memory use, undermining the case for 90% margins despite a long-term shortage. Memory is the only layer raising cost per token. Elon Musk described Micron's future pricing as reasonable and other suppliers' as extortionate, warning that today's customers would not forget; exorbitant long-term contracts compound that risk. x.com x.com
More memory CapEx may yield proportionally fewer bits as HBM consumes more wafer capacity, supporting SK hynix and Samsung's pricing. Both reported double-digit quarterly DRAM and NAND price gains; Samsung targets 60-70% of mid- to long-term capacity under LTAs. SK hynix has the stronger execution record, but Samsung could benefit enormously from conventional memory without winning HBM4. If trends persist, normalized margins could rise, though memory remains cyclical. x.com
SK hynix's exceptional margins and contracted capacity underpin a bullish outlook despite shares sitting around half their June high. Q3 operating margin reached 80%, up from 47% a year ago; long-term deals with 14 customers cover over half of 2027-28 capacity, and management expects demand to exceed supply through 2030. x.com
Nvidia's proposed common NVHBM base die would make Micron, SK hynix and Samsung more interchangeable, weakening their pricing power. Seoul Economic Daily reports Nvidia wants all three to fabricate it at TSMC; Samsung reportedly agreed. Standardization would ease validation and order shifts. The risk lessens if SK hynix or Micron retain their own logic or NVHBM stays a small share of Nvidia's purchases. x.com
Memory remains structurally scarce because SK hynix says conventional DRAM and HBM are practically sold out through 2029, while customers request roughly twice the HBM volume it can produce. Long-term agreements cover more than half of 2027 and 2028 capacity, and the company expects the supply-demand imbalance to persist through 2030. x.com x.com
