Timothy D. Cook (born November 1, 1960) is the CEO of Apple, a position he has held since August 24, 2011, when he succeeded co-founder Steve Jobs after joining the company in 1998 as a senior vice president for worldwide operations. Under his leadership, Cook replaced Jobs' micromanagement with a more collaborative culture, and between 2011 and 2020, he doubled the company's revenue and profit, boosting its market value from $348 billion to $1.9 trillion—with revenue reaching $416 billion by 2025. Beyond Apple, Cook has served on the board of Nike since 2005 and is a trustee of Duke University, his alma mater, while also pledging to donate his fortune to charity. In 2014, he made history as the first CEO of a Fortune 500 company to publicly come out as gay, and he has been named to Time's 100 most influential people list in 2012 and 2021. In April 2026, Apple announced that Cook would step down as CEO on September 1, 2026, with John Ternus named as his successor.
