John Ternus, Apple’s senior vice president of hardware engineering, will become the company’s CEO on September 1, 2026, marking the technology giant’s first leadership change in 15 years. Tim Cook, who has led Apple since 2011, is stepping down from the chief executive role but will remain as executive chairman, maintaining influence over the company’s strategic direction.
Ternus, 51, is a 25-year veteran of Apple who joined the company in 2001 as a mechanical engineer on the product design team. Throughout his tenure, he has risen through the engineering ranks and, since 2021, has overseen all of Apple’s hardware engineering—the division responsible for developing the iPhone, iPad, Mac, and other core products that generate roughly 80% of the company’s revenue.
The transition was announced in April 2026 and represents a strategic shift toward product-focused leadership. Ternus holds a bachelor’s degree in mechanical engineering from the University of Pennsylvania and worked as a mechanical engineer at Virtual Research Systems before joining Apple. His appointment signals that the company intends to emphasize hardware innovation and engineering excellence under new leadership.
The move mirrors Apple’s previous CEO transition, though with a different trajectory. When Tim Cook took over in August 2011 following Steve Jobs’ resignation, the succession occurred with minimal transition time—Jobs died weeks later. In contrast, the Ternus transition has been carefully orchestrated over several months, allowing for a smoother handoff. Cook’s 15-year tenure saw Apple grow from a market capitalization of roughly $350 billion to nearly $4 trillion, according to reporting from multiple outlets.
Ternus will face immediate high-profile challenges. Apple has scheduled a major product launch event for September 9, 2026—just eight days after he assumes the CEO role—where the company is expected to unveil new iPhones and Apple Watches, including its first foldable iPhone. This will be his first keynote presentation as CEO and a defining early moment for his leadership.
Analysts have highlighted both the promise and the pressure of Ternus’s appointment. His deep hardware expertise positions him to drive product innovation, but observers note that he will need to address challenges including Apple’s competitive position in artificial intelligence, where the company has lagged behind rivals, and sustaining growth in a maturing smartphone market. The selection of a hardware engineer as CEO represents a deliberate choice to prioritize product design and engineering over operational or financial expertise, the latter of which defined Cook’s tenure.
Cook will continue as executive chairman, serving on Apple’s board of directors and remaining available to guide strategy. This arrangement allows Ternus to lead day-to-day operations while Cook provides continuity and counsel—a structure designed to balance leadership renewal with institutional stability.
