SK Hynix Reports Record Q1 Profit on Rising Memory Prices
SK Hynix reported record first-quarter profit and revenue driven by surging memory prices and strong AI demand, particularly for high-bandwidth memory (HBM). Revenue for Q1 was 52.58 trillion won ($35.55 billion), slightly below LSEG smart estimates, while operating profit was 37.61 trillion won. The company cited expanded AI infrastructure spending and rising demand as factors sustaining pricing and profitability, and said agentic/real-time inference trends will further increase memory needs. SK Hynix dominates the HBM market (about 57% share) and plans to invest 19 trillion won in a new South Korean plant. SK Group’s chairman warned wafer shortages could persist until 2030, and SK Hynix expects to sample HBM4E in H2 2026 with mass production targeted for 2027.
SK Hynix’s $720B AI Memory Buildout in South Korea
SK Hynix is investing $720 billion to build what it says will be the world’s largest network of memory factories, driven by rising AI demand for high-bandwidth memory (HBM). The company, now with a market capitalization above $1 trillion, raised $26.5 billion in July through a Nasdaq listing to help fund the expansion. SK Hynix controls a majority share of the HBM market and has signed long-term supply agreements with major customers, including collaboration with Nvidia. The buildout includes multiple new fabs in South Korea and a $4 billion packaging facility planned in Indiana; export controls limit sales of SK Hynix’s leading HBM products in China.
SK Hynix Reaches $1 Trillion Valuation
SK Hynix’s shares have risen roughly 250% year-to-date, pushing its market capitalization above $1 trillion amid surging AI-driven demand for high-bandwidth memory (HBM), DRAM and NAND. Analysts quoted by CNBC — including Peter Kim of KB Securities and Dan Ives of Wedbush — said the rally could have more room to run: Kim noted SK Hynix and Samsung trade at roughly six-to-seven times earnings versus Micron at about 12 times, while Ives described the AI boom as in the “3rd inning of a 9-inning game.” Analysts point to cloud and Big Tech capital expenditure (projected at roughly $725 billion) sustaining chip demand. The coverage also highlights concentration risks in South Korea’s Kospi, where SK Hynix and Samsung account for more than 40% of the index, and warns that overcapacity — the usual cycle-ender — is not expected for a couple of years.
