SK Hynix Surges Past Samsung, Becomes South Korea's Top Tech Giant

SK Hynix achieved a landmark moment on Monday, surpassing Samsung Electronics to become South Korea's most valuable listed company. This ascendance signifies a profound reversal for the chip manufacturer, which was on the brink of collapse due to debt nearly two decades ago.

Now a leading supplier of high-bandwidth memory (HBM) chips essential for AI systems, SK Hynix has capitalized on the global AI boom. Its shares have experienced an extraordinary surge of over 340% this year.

This market leadership in AI-critical components, including those for Nvidia and Google, has propelled its market capitalization. The company's focus on specialized memory chips has made them vital infrastructure for advanced AI applications, contrasting with Samsung Electronics' broader chip and electronics manufacturing.

SK Hynix's journey represents one of South Korea's most impressive corporate turnarounds. In 2002, then Hynix Semiconductor was slated for sale after accumulating substantial debt. The deal eventually fell through, leaving the company under creditor control for almost a decade, with its shares once falling as low as 135 won in 2003.

After navigating the traditional boom-and-bust cycles of the memory industry, SK Hynix reported a significant annual operating loss of 7.73 trillion won in 2023. However, the company began its recovery as the AI boom intensified, leading to a record annual operating profit of 23.5 trillion won in 2024.
