Ternus, who took the reins from Tim Cook in September, has overseen the introduction of Apple's first foldable phone, smart home hub and touch-screen laptops. All of those products began shipping during the company's current fiscal first quarter, amid what Cook had called a "100-year flood" of rising memory costs.

Apple will face scrutiny over three key issues: its crucial holiday-quarter outlook, Ternus' remarks on AI and the revamped Siri, and rising memory-chip costs that analysts expect to drag quarterly profit growth to its weakest in six quarters.
