John Ternus, who became Apple's chief executive on Sept. 1 after Tim Cook moved to executive chairman, will deliver his first major product keynote on Sept. 9 at Apple Park. Apple is expected to unveil iPhone 18 Pro and Pro Max models, its first foldable iPhone, Apple Watch Series 12 and Apple Watch Ultra 4, while the standard iPhone 18 is reportedly delayed until 2027. Preorders are scheduled to open Sept. 12 and iPhone 18 Pro models are due to become available Sept. 18; the foldable iPhone's release date remains unconfirmed. A Sept. 7 filing set Cook's fiscal 2027 target compensation at $47 million and Ternus's at $58 million, largely through restricted stock units. Cook is expected to retain responsibilities including policy coordination, Chinese government relations and memory-chip supply issues as Ternus takes charge of Apple's hardware and artificial-intelligence agenda.
