Nvidia supplier SK Hynix second-quarter profit and revenue hit record highs, topping estimates

• Revenue rose about 35% in the June quarter compared with the same period a year earlier, while operating profit rose 68%, year on year.
• SK Hynix has established itself as the global leader in high bandwidth memory — a type of DRAM used in artificial intelligence servers.

South Korea's SK Hynix on Thursday posted record operating profit and revenuein the second quarter on sustained demand for its high bandwidth memory technology used in generative AI chipsets.

Here are SK Hynix's second-quarter results compared with LSEG SmartEstimates, which are weighted toward forecasts from analysts who are more consistently accurate:

• Revenue:22.23 trillion won vs. 20.56 trillion won
• Operating profit:9.21 trillion won vs. 9 trillion won

Revenue rose about 35% in the June quarter compared with the same period a year earlier, while operating profit rose over 68%, year on year.

On a quarter-on-quarter basis, revenue rose 26%, while operating profit jumped 24%.

The company said in a statement that it enjoyed strong demand and favorable pricing conditions in the first half of the year. SK Hynix added that there was a low likelihood of sharp demand corrections for the rest of 2025, due to stable customer inventory levels and expected demand from new product launches.

SK Hynix is a leading supplier of dynamic random access memory — a type of volatile semiconductor memory commonly found in PCs, workstations and servers that is used to store data and program code.

Much of the company's recent success can be credited to its business in high bandwidth memory, or HBM — a type of DRAM used in artificial intelligence servers.

SK Hynix has established itself as the global leader in HBM, supplying clients such as U.S. AI darling Nvidia.

Micron Technology and Samsung Electronics are the other memory players seeking to catch up to SK Hynix in the HBM space. However, analysts expect SK Hynix's dominance to persist through this year.
