KB Securities: Samsung HBM4 sales increased more than three times month-on-month, and the foundry business is expected to turn a profit in the third quarter

KB Securities released a report on September 11, indicating that Samsung Electronics' HBM market share is expected to increase from 33% in the second quarter to 40% in the fourth quarter, mainly due to HBM4 sales in the third quarter growing more than three times quarter-on-quarter, and HBM4 is expected to account for over 60% of its total HBM sales in the second half of the year.

Samsung Electronics has established comprehensive mass production of HBM4, supplied HBM4E samples to core customers, adopted the HBM5 architecture with 1c core bare chips and 2-nanometer base bare chips, and outlined the roadmap for the next-generation ZHBM. In terms of its foundry business, the 4-nanometer yield has stabilized above 80%, and the 2-nanometer GAA yield has rapidly increased to over 70%. KB Securities analyst Kim Dong-Won stated that the foundry business is expected to turn profitable starting in the third quarter, and the 2-nanometer yield may help it secure orders from major U.S. clients within the year.
