Q2 2026 Preliminary Consolidated Results: Revenue +257% YoY, Operating Income +557% YoY — SK Hynix

Summary

SK Hynix reported blowout preliminary Q2 2026 results with revenue of KRW 79.3 trillion (up 50.9% QoQ and 256.8% YoY), driven by surging HBM and AI-related DRAM demand. Operating income reached KRW 60.5 trillion (+61.0% QoQ, +557.2% YoY), implying an operating margin of approximately 76%, an extraordinary level for a memory semiconductor company. A notable anomaly: pre-tax income from continuing operations (KRW 122.7 trillion) more than doubled operating income, indicating massive non-operating gains—likely from equity-method investments or financial asset revaluations—that warrant scrutiny. On a cumulative H1 2026 basis, revenue of KRW 131.9 trillion and operating income of KRW 98.2 trillion already dwarf full-year 2025 figures. These are unaudited preliminary figures subject to revision upon completion of the external audit.
