John Ternus assumes leadership of Apple on Wednesday, inheriting a mandate to restructure the company’s executive ranks while navigating a critical period for artificial intelligence integration and product development.
Ternus succeeds Tim Cook, who will transition to Executive Chairman after 15 years as CEO. Cook’s tenure was marked by operational stability, though his leadership style—rooted in hardware expertise—now faces scrutiny as Apple seeks to modernize its management structure and accelerate AI adoption. The company’s long-standing executive team, which has defined its corporate culture for decades, is undergoing a generational transition initiated in 2024.
Cook’s planned departure prompted a phased leadership handover. Luca Maestri, long-serving CFO, stepped down at the end of 2024 but remains on payroll for real estate and IT oversight. Chief Operating Officer Jeff Williams retired in late 2025, followed by General Counsel Kate Adams and Environmental Affairs head Lisa Jackson. Ternus now inherits a leadership vacuum across finance, operations, legal, and retail, with several key roles still unfilled.
The executive restructuring coincides with Apple’s push to close its AI gap. After initial stumbles with its proprietary Apple Intelligence models, the company pivoted to integrating Google’s Gemini technology into Siri. Internal discontent over the shift led to developer departures, though early evaluations of the new Siri system have been positive. Apple plans to monetize the enhanced Siri through subscriptions or third-party integrations, with a formal rollout slated for September.
Ternus, who previously led Apple’s hardware division, is leveraging AI to streamline product development and enhance device functionality. The company is preparing updated versions of Apple TV and HomePod mini, while addressing delays in camera-equipped AirPods and home devices attributed to software deficiencies. New Siri capabilities are expected to resolve these issues, though the company has restricted video recording in certain devices to comply with privacy protocols.
Key executives facing transition include Deirdre O’Brien (Retail and People), Johny Srouji (Hardware), and Greg Joswiak (Marketing). O’Brien, a close Cook ally, is expected to retire within three years, with Vanessa Trigub positioned as her retail successor. Srouji, who oversaw Apple’s transition from Intel to proprietary chips and modem development, is likely to depart within one to two years, prompting a potential split of the hardware division into engineering and technology units. Joswiak, a 40-year Apple veteran, is also expected to retire, with internal candidates like Lilian Rincon and Kaiann Drance in contention for marketing leadership.
Under Ternus, service chief Eddy Cue, CFO Kevan Parekh, and COO Sabih Khan will assume greater responsibilities. Parekh, who joined Apple in 2015, is expected to remain in his role for at least another decade, with Asha Kamath groomed as a potential successor. Khan’s deputy, Priya Balasubramaniam, is poised for a senior vice president promotion and eventual COO succession. Cue’s portfolio, encompassing entertainment, music, and sports, may be divided upon his eventual retirement, with Oliver Schusser and Adrian Perica emerging as candidates for leadership roles.
