BH shares rose 6.47% in early KOSPI trading on the 14th after Apple unveiled its first foldable iPhone, the book-style iPhone Duo, in Cupertino on September 9. The device starts at $1,999 in the United States and 3.29 million won in South Korea, intensifying competition with Samsung Electronics while creating a supply-chain opportunity for Samsung Display, which industry sources identify as the effective sole supplier of its foldable OLED panel. BH manufactures flexible printed circuit boards (FPCB) used in foldable phones and is recognized as a key supplier to Samsung Electronics and Apple. Counterpoint Research estimates Apple could account for about 29% of foldable-panel procurement this year, or roughly 8 million panels, while research firms expect Apple to rank second in foldable-phone shipments during its first year. The reported $250 panel price and three-year exclusive-contract claims have not been officially confirmed.
