Micron rises after rival SK Hynix posts record sales and profits
Micron shares are continuing their meteoric rise after South Korean competitor SK Hynix reported record earnings for the final quarter of 2025, underscoring the continued demand for the world’s three leading memory chip manufacturers — SK Hynix, Micron, and Samsung — fueled by rampant AI capital expenditure.
Driven by demand for its high-bandwidth memory (HBM) products, a higher-margin memory product essential for AI accelerators, the company posted a record 32.8 trillion won (~$22.6 billion) in revenue and 19.2 trillion won ($13.2 billion) in operating profit for the fourth quarter. The company’s shares were up more than 6% in trading in Korea.
SK Hynix also announced on Wednesday that it will commit at least $10 billion as it restructures a subsidiary to establish a new US-based company specialized in finding “new AI growth engines.” Management also continues to consider listing its shares in the US.
SK Hynix’s latest performance reflects the strong demand for HBM3E, its cutting-edge DRAM product, for which the Korean firm is the main supplier to Big Tech companies like Nvidia and Microsoft. Micron is second to SK Hynix’s dominance in the HBM space in market share.
Elsewhere in the AI memory and storage space, Seagate’s robust quarterly results and strong guidance is helping to lift sentiment further.
Micron, Western Digital, and Sandisk are soaring in premarket trading stateside, while Samsung shares popped up a smaller 2% at Wednesday’s close in Korea.
