Today marks the end of Tim Cook’s tenure as CEO of Apple, but not his connection to the company. On his final day, he shared a heartfelt memo with the Apple workforce reflecting on his years in leadership, celebrating the company’s culture, and publicly endorsing John Ternus as his successor.
Cook’s leadership transition has been unfolding for months. His departure as CEO was announced in April 2026, with John Ternus named to take over. Still, it wasn’t until today—August 31, 2026—that Cook officially stepped aside. The company held his going-away event on August 24. At the same time, Cook steps into a newly-defined role at Apple, moving from CEO to a position described as Chief Executive, a title crafted to support Ternus however he needs. As Cook put it, he isn’t leaving Apple—he’s just changing roles.
A Message Rooted in Gratitude and Identity
In his memo addressed to all employees, Cook expressed deep appreciation for the contribution and dedication of Apple’s people. He emphasized that the success he is credited with belongs wholly to the team, crediting them with bringing out the best individually and collectively. He praised Apple’s culture—one he describes as existing long before anyone joined, powered by shared beliefs that what Apple builds matters and that the company has an obligation to leave the world a better place.
Cook reflected on the power of community at Apple—how employees lift one another up, foster purpose, and unite under values that emphasize impact over metrics. He admired the company’s commitment to building products that change the world and a culture that goes beyond what any number on a report could capture.
Leadership Handoff and What’s Next
Cook celebrated John Ternus, describing him as amazingly capable and full of the enthusiasm needed to lead Apple into its next chapter. He said few understand what it means to build truly transformative products like Ternus does, and that passing the reins to him fills Cook with excitement and confidence.
Though Cook says he’ll miss the routine of leading the company and being hands-on every day, he affirmed he’s “completely at peace” with his decision. He looked forward to contributing in his new capacity, being present at Apple Park, and engaging with employees and customers around the world in this next phase.
With Cook stepping down, it’s clear his era has ended, officially marking the beginning of Ternus’s leadership. The baton has been passed in form and in spirit.
Why It Matters: Cook’s exit as CEO marks a generational shift. Ternus has been visible within Apple’s hardware ranks but has yet to lead the company through a full innovation cycle under his own vision. The incoming era will test whether Apple’s strengths—its culture, its product strategy, customer trust—can be preserved without losing momentum.
