Tim Cook’s run as Apple chief executive is ending. The Verge reports that it was Cook’s last day as Apple CEO, and Axios reports that Cook hands the reins to John Ternus on Tuesday, after 15 years running the company. The transition closes the central post-Steve Jobs chapter in Apple’s modern history. According to The Verge, Cook became CEO in 2011 and carried forward the iPhone era while Apple grew into one of the world’s most powerful consumer technology companies. Axios framed the tenure as an unusually strong corporate run, though the feed summary in this cluster does not include the specific financial figures behind its chart. The Verge published Cook’s final message to Apple employees, saying the letter had also been reported by Bloomberg and 9to5Mac. In the note, Cook thanked staff for what he described as the privilege of serving as their leader and credited Apple’s employees for the company’s success during his tenure. Cook’s message emphasized Apple’s culture and the idea that the company’s work is bigger than any single executive. The note, as published by The Verge, says Cook is stepping away from a role he loved deeply, but also says he is not leaving Apple. The provided items do not specify what role he will hold next. The handoff now moves attention to Ternus. The Verge refers to him as Apple’s new CEO, and Axios says he receives the reins Tuesday. The sources in this cluster do not provide details on Ternus’s strategy, management changes, or product priorities, so the immediate reported fact is the leadership transfer itself. For Apple, the practical question is continuity. Cook’s farewell note, as summarized and published by The Verge, presents the transition as an internal handoff rather than a break with Apple’s operating culture. Investors and operators will now be watching whether Ternus preserves that continuity while taking formal control of one of the most scrutinized companies in technology. Who benefits: John Ternus gains the CEO role at Apple. Apple employees also get a continuity message from Cook, who told staff he is not leaving the company even as he exits the CEO role. Who's exposed: Apple investors and partners face leadership-transition uncertainty until Ternus’s priorities become clearer. The provided reports do not establish any immediate operational or financial disruption.
