It became the world's leading memory chip supplier by revenue in Q4 2025, bringing in $26 billion. This stellar performance enabled the company to overtake its cross-town rival SK Hynix, which enjoyed an early lead over Samsung particularly in the lucrative high-bandwidth memory segment. The surge in revenue was driven by strong sales of high-value products including high-bandwidth memory chips and server DRAM. While SK Hynix lost out the top spot to Samsung in terms of revenue, it maintained excellent margins. The report mentions that SK Hynix set an industry record with a 58% operating profit margin.
