🚀 2. [Market Opportunities & Business Outlook]

  • 2Q26 Earnings Review
    • 2Q26 revenue reached KRW 79.3T (QoQ +51%) and operating profit recorded KRW 60.5T (QoQ +61%), marking five consecutive quarters of record-high operating profit.
    • Operating margin rose to 76% propelled by higher shipments, price increases, and cost reductions across both DRAM and NAND, demonstrating solid performance despite the postponement of some high-value product shipments to the second half.
    • Estimated metrics indicate DRAM B/G +6%, ASP +30%, and operating profit of KRW 48.2T (OPM 83.0%), alongside NAND B/G +13%, ASP +49%, and operating profit of KRW 13.1T (OPM 66.0%), with sharp price surges leading earnings growth over mere volume growth.
  • Second-Half Earnings Momentum & LTA Achievements
    • In the second half, volume and product mixes are expected to improve simultaneously through expanded shipments of HBM4 and 1c-node based products.
    • Mass production and shipments of HBM4 commenced in Q2, with full-scale production ramp-up scheduled for the second half; furthermore, long-term agreements (LTAs) have been finalized with approximately 10 key clients, securing mid-to-long-term demand visibility.
    • Considering the widespread proliferation of AI services and sustained infrastructure investments by CSPs, second-half earnings growth momentum is projected to persist.

📝 Editor’s Comment (Perspective & Thesis Verification)

The analyst evaluates SK hynix as a leading semiconductor enterprise maintaining robust earnings growth backed by expanded HBM4 mass production, rising shipments of 1c-node server DRAM, and enhanced mid-to-long-term demand visibility through finalized LTAs. This perspective places greater emphasis on the structural durability of the memory cycle, second-half earnings growth, and anticipated additional shareholder return announcements within the year as catalysts for stock recovery, rather than short-term market corrections driven by rising Chinese memory competition or big-tech credit risk concerns.

To verify whether this investment thesis unfolds as expected going forward, it is necessary to track whether full-scale mass production and shipments of HBM4 and 1c-node products translate into actual earnings enhancements, whether the finalized LTAs with key clients solidify visible mid-to-long-term demand, and whether additional shareholder return policies are formally announced and executed within the year. Such changes can be verified through future quarterly earnings releases, official company IR materials, and regulatory filings.
