Tim Cook will step down as Chief Executive Officer of Apple Inc. in September, marking the end of a transformative era for the tech giant. He will be succeeded by longtime executive John Ternus.
According to the announcement, Cook will transition into the role of Executive Chairman of Apple’s board after relinquishing the CEO position. He described his tenure as the “greatest privilege” of his life, noting his long-standing commitment to leading the company through years of innovation and global expansion.
Cook joined Apple in 1998 and later became CEO in 2011 following the departure of co-founder Steve Jobs. Under his leadership, Apple expanded its product ecosystem and significantly grew its global market valuation to around $4 trillion.
His successor, John Ternus, has been with Apple since 2001 and has played key roles in the development of major products including the iPhone, iPad, Apple Watch, and Mac lineup. Ternus expressed gratitude for the opportunity, acknowledging the mentorship of both Jobs and Cook.
The leadership transition comes as Apple marks its 50th anniversary while navigating growing competition in artificial intelligence and maintaining its position as one of the world’s most influential technology companies.
