SK hynix reported preliminary second-quarter revenue of 79.3 trillion won and operating profit of 60.5 trillion won on July 29, both quarterly records, with a 76% operating margin. The memory maker attributed the increase to strong AI-infrastructure demand and higher DRAM and NAND prices, and said HBM4 mass shipments began during the quarter.
SK hynix reported preliminary K-IFRS results for the second quarter on July 29, posting 79.3187 trillion won in revenue and 60.5426 trillion won in operating profit. Both were quarterly records, and the operating margin reached 76%.
The company also reported 93.9226 trillion won in net income. Because that figure exceeded quarterly revenue, readers should treat it as a reported accounting result rather than a measure of operating performance. SK hynix said the figures remain preliminary pending the independent audit process.
AI demand lifts memory pricing
Revenue increased 51% from the first quarter and 257% from a year earlier. Operating profit rose 61% quarter over quarter and 557% year over year, according to the company's results table. SK hynix attributed the gains to higher prices across DRAM and NAND flash and stronger sales of high-value products for AI servers.
Yonhap independently reported the record earnings from the company's regulatory filing. Its report also cited Counterpoint Research estimating that SK hynix held 58% of the global high-bandwidth-memory market by revenue in the first quarter; that market-share estimate is separate from SK hynix's second-quarter financial statements.
HBM4 shipments and longer contracts
SK hynix said it began mass shipments of HBM4 in the second quarter and plans to increase production in the second half. It also said HBM4E samples were shipped during the first half, while providing no customer-level shipment volumes in the release.
The company said it has completed long-term agreements with around 10 customers, including strategic partners, and remains in discussions with other major clients. It did not identify those customers or disclose the commercial terms.
For data and AI infrastructure teams, the practical signal is that memory pricing, supply allocation and multi-year purchasing commitments are becoming central constraints in AI-capacity planning. That is an LDS interpretation of the disclosed results; the durability of demand and the pace of capacity expansion remain forward-looking.
