On July 29, 2026, SK hynix announced second-quarter 2026 results: revenue of 79,318.7 billion won, operating profit of 60,542.6 billion won, and net income of 93,922.6 billion won. Operating margin reached 76 percent. The company headlined the release as “Record-Breaking Quarterly Performance Driven by High-Value Product Sales Amid Strong AI Demand,” noting that cumulative first-half revenue passed 100 trillion won for the first time.
On product, SK hynix said HBM4 “achieved customer-required operating speeds while delivering industry-leading power efficiency and cost competitiveness,” began mass shipments during the quarter, and will ramp production in the second half of the year. Sample shipments of the follow-on HBM4E were completed in the first half.
The balance sheet moved as sharply as the income statement. Cash and cash equivalents reached 88 trillion won at quarter end, total debt fell to 18.6 trillion won, and the net cash position expanded to 69.4 trillion won. A 76 percent operating margin is not a normal semiconductor result; it is what a genuine supply shortage looks like. High-bandwidth memory has become the binding constraint on AI accelerator output, and this quarter shows the economic rent of that bottleneck accruing to the memory maker rather than to the chip designers or the cloud buyers spending tens of billions on capacity.
