1. SK hynix H1 2025: What Happened?

SK hynix reported remarkable earnings for the first half of 2025, with revenue reaching 39.87 trillion KRW and operating profit hitting 16.65 trillion KRW. The DRAM division saw shipments surge by over 20%, driven by strong HBM sales and server/PC demand.

The company’s financial health also improved, with a debt-to-equity ratio of 48.13% and a net debt-to-EBITDA ratio of 5.60%.

2. Why the Earnings Surge?

The primary driver of this earnings surge is the explosive growth of the AI market. The advent of generative AI services like ChatGPT has led to a surge in demand for high-performance memory semiconductors, especially HBM. SK hynix, with its technological leadership in this market, has secured high profitability. The overall recovery of the semiconductor market and stable demand from the server/PC market also contributed positively to the results.
