Tim Cook will step aside as chief executive of Apple later this year, marking the end of an era that reshaped the tech giant following the legacy of Steve Jobs. The company confirmed on Monday that John Ternus, currently senior vice president of hardware engineering, will assume the CEO role effective September 1.
Cook, who has helmed Apple since 2011, will transition into the position of executive chairman of the board while remaining CEO through the summer months to oversee a steady handover. In a company statement, he described his tenure as the “greatest privilege” of his career, signalling that the move represents a transition rather than a full departure.
The leadership change comes amid broader executive reshuffling at Apple in late 2025, including exits involving its artificial intelligence chief, policy leader and a key design executive. Industry observers view these developments as part of a wider recalibration as the company faces intensifying competition in emerging technologies.
During his 15-year leadership, Cook expanded Apple far beyond its core products such as the Mac, iPod and iPhone, transforming it into a powerhouse spanning services, entertainment, health and wearables. While Jobs introduced the iPhone, it was under Cook that the device evolved into a central ecosystem, enabling the success of products like Apple Watch, AirPods and Apple TV+. This strategic shift helped Apple grow into one of the most valuable companies globally, underscoring how leadership continuity can shape long-term corporate identity.
At the same time, Apple encountered challenges in newer ventures, particularly in artificial intelligence and virtual reality. Products like the Vision Pro headset have yet to achieve mainstream traction, while delays in enhancing Siri have placed Apple behind rivals such as OpenAI and Google. These hurdles have prompted increasing scrutiny from analysts, especially regarding the company’s readiness for a future less reliant on the iPhone.
Beyond product innovation, Cook’s tenure was defined by his handling of major global events. He steered Apple through the COVID-19 pandemic, including early global retail closures, and navigated complex geopolitical pressures such as trade tensions between the United States and China under Donald Trump. His leadership also saw commitments to expand Apple’s domestic manufacturing footprint in the US.
Ternus, widely regarded as Cook’s successor for several years, brings deep institutional knowledge, having joined Apple in 2001. Rising through the ranks, he played a critical role in hardware development, including contributions to the iPad and AirPods, and most recently led the rollout of the MacBook Neo. His appointment signals continuity, though expectations remain high as Apple enters a crucial phase of innovation.
Looking ahead, Apple is anticipated to introduce major updates, including advancements to Siri and potential hardware breakthroughs such as a foldable iPhone. Analysts note that Ternus will face immediate pressure to deliver results, particularly in artificial intelligence, as the company seeks to maintain its competitive edge in a rapidly evolving tech landscape.
