SK Hynix Q1 Operating Profit $29B - 70% Margin Surpasses TSMC (2026)
Operating profit margin refers to the percentage of revenue that remains as profit after covering operating costs. SK Hynix's projected 70% operating margin for Q1 2026 signals a fundamental shift in how the market values memory semiconductors in the AI era. If you follow semiconductor investing, this is the number to watch.
What drove SK Hynix's $29B quarter?
The global expansion of AI services has triggered an explosion in demand for memory chips used in data centers. DRAM prices surged 90-95% quarter-over-quarter, driven by AI server procurement. SK Hynix's flagship product HBM (High Bandwidth Memory - the ultra-fast memory essential for AI chips) is sold out through the end of 2026. Every unit produced is already spoken for, marking the onset of the "memory supercycle."
$29B profit and a 20pp gap over TSMC
Analysts project SK Hynix's Q1 operating profit at approximately $29 billion (KRW 40 trillion). Kiwoom Securities estimates KRW 40.3 trillion, while Heungkuk Securities forecasts KRW 40.1 trillion. At a 70% operating margin, SK Hynix would surpass TSMC's 54-56% margin by nearly 20 percentage points. A memory company outperforming the world's dominant foundry on profitability is without precedent in semiconductor history.
What does this mean for investors?
SK Hynix's full-year operating profit forecast stands at $182 billion (KRW 251 trillion), positioning the company for a #4 ranking globally behind Microsoft, Alphabet, and Apple. Korean semiconductors are no longer just "manufacturing" - they rank among the most profitable industries on earth. Memory chips are becoming core strategic assets rather than commodity components.
How long will the memory supercycle last?
AI infrastructure investment continues to accelerate, with major big tech companies planning data center expansions through 2027. Samsung Electronics also posted a record Q1 operating profit of KRW 57.2 trillion. However, production expansion by Chinese memory firms and evolving US-China semiconductor restrictions remain key variables to monitor.
Key Takeaways
① $29B operating profit - SK Hynix posts all-time record, up 110% from the prior quarter
② 70% margin - Surpasses TSMC (54%) by 20pp, highest profitability in global semiconductors
③ $182B annual outlook - On track for global #4 in profit as the AI memory supercycle intensifies
SK Hynix's record quarter proves that memory chips have evolved from commodity parts into strategic assets defining the AI era. For anyone tracking semiconductor investments, the structural shift in the memory industry deserves close attention.
