SK hynix reported record-breaking 2Q26 financial results on July 29, 2026, driven by intense AI memory demand and higher chip prices. Yet, stock price took a huge dip...
What will SK Hynix operating profit margin be for 3Q2026 (vs 2Q2026)?
TL;DR:
What's Good: Absolute profit and revenue growth were extraordinary by any historical standard. Operating profit of ₩60.54 trillion was up more than 550% year over year, and revenue and operating profit increased 257% and 557% year-over-year, respectively.
What's Good: Long-term contract book was locked in with key customers. SK hynix has finalized Long-Term Agreements with around 10 customers, including key strategic partners, aiming to secure mid-to-long-term supply stability, improve operational efficiency, and support sustainable growth.
What's Good: HBM4 hit technical milestones and began shipping. SK hynix began mass shipments of HBM4 in Q2 2026 and plans to ramp production in the second half, and HBM4 achieves customer-required operating speeds, industry-leading power efficiency, and cost competitiveness, demonstrating differentiated technological edge.
What's Good: Structural position within the AI memory shortage remains dominant. Goldman Sachs has estimated a 2026 DRAM supply-demand gap of 4.9%, described as the most severe shortage in 15 years, with DRAM spot prices up approximately 52% since January 2026, and industry analysts estimate SK Hynix holds approximately 60 to 70% of Nvidia's HBM4 allocation for the Vera Rubin AI platform, with Samsung capturing roughly 25-30% and Micron supplying the remainder — an allocation confirmed publicly by Nvidia CEO Jensen Huang during a Seoul visit in June.
What's Missed: Operating profit missed consensus by a meaningful margin, despite the YoY headline.
What's Missed: Multi-year HBM supply contracts are structurally capping upside capture. Korea Investment & Securities projected Q2 operating profit roughly 8% below consensus, revealing how the company's multi-year high-bandwidth memory supply contracts prevent it from capturing the full spot-price upside investors were modeling — the company is essentially leaving spot-market pricing gains on the table in exchange for locked-in volume certainty.
What's Missed: HBM4 ramp timing came in later than some analysts had priced. Investors had anticipated that shipments of SK Hynix's next-generation HBM4 [would scale in Q2], [but] that increase had not materialized at scale. Full-scale HBM4 mass production is now expected to begin in the third quarter of 2026 — a shift that also removed a source of upside analysts had priced into Q2 estimates.
Key Debates:
Is the "miss" actually a demand problem, or purely a contract-structure artifact?
How much of the sell-off is stock-specific versus sector-wide noise?
Does the HBM4 delay to Q3 change the growth trajectory, or just shift timing?
