SK Hynix is a golden goose. It has to lay more eggs

Talk about K-power. South Korea’s SK Hynix Inc. has raised $26.5 billion from the US stock market, the biggest first-time share sale by a foreign company. The question now is whether the trillion-dollar firm can satisfy competing demands from exacting stakeholders.

Investor enthusiasm stems from the fact that SK Hynix has morphed into a golden goose. It’s the world’s second-largest supplier of dynamic random-access memory chips, or DRAM, and the biggest when it comes to the high-bandwidth ones that are paired with Nvidia Corp.’s graphics processing units.
