Cook will continue on as Apple CEO through the summer, with Ternus set to join Apple's Board of Directors and take over as CEO on September 1, 2026.
Cook is going to transition to chairman of the board at Apple, and he will "assist with certain aspects of the company, including engaging with policymakers around the world."
Tim Cook, led Apple to become a $4 trillion company and defined its identity in the post-Steve Jobs era.
John Ternus, currently Apple’s senior vice president of hardware engineering, will take over as CEO effective September 1. Cook will become executive chairman of Apple’s board of directors and will remain as CEO through the summer to ensure a smooth transition, the company said.
In a statement released on Monday [April 20, 2026], Cook said that his time as Apple's CEO has been the "greatest privilege" of his life.
"It has been the greatest privilege of my life to be the CEO of Apple and to have been trusted to lead such an extraordinary company. I love Apple with all of my being, and I am so grateful to have had the opportunity to work with a team of such ingenious, innovative, creative, and deeply caring people who have been unwavering in their dedication to enriching the lives of our customers and creating the best products and services in the world. John Ternus has the mind of an engineer, the soul of an innovator, and the heart to lead with integrity and with honor. He is a visionary whose contributions to Apple over 25 years are already too numerous to count, and he is without question the right person to lead Apple into the future. I could not be more confident in his abilities and his character, and I look forward to working closely with him on this transition and in my new role as executive chairman.
Ternus said that he is optimistic about what Apple can achieve in the years to come.
"I am profoundly grateful for this opportunity to carry Apple's mission forward. Having spent almost my entire career at Apple, I have been lucky to have worked under Steve Jobs and to have had Tim Cook as my mentor. It has been a privilege to help shape the products and experiences that have changed so much of how we interact with the world and with one another. I am filled with optimism about what we can achieve in the years to come, and I am so happy to know that the most talented people on earth are here at Apple, determined to be part of something bigger than any one of us. I am humbled to step into this role, and I promise to lead with the values and vision that have come to define this special place for half a century."
Apple says that the transition was approved by the Board of Directors and is the result of a "thoughtful, long-term succession planning process." The current board chair, Arthur Levinson, will become the lead independent director on the board.
To the Apple community:
For the past 15 years I’ve started just about every morning the same way. I open my email and I read notes I received the day before from Apple’s users all over the world.
You share little pieces of your lives with me and tell me things you want me to know about how Apple has touched you. About the moment your mom was saved by her Apple Watch. About the perfect selfie you captured at the summit of a mountain that seemed impossible to climb. You thank me for the ways Mac has changed what you can do at work and sometimes give me a hard time because something you care about isn’t working like it should.
In every one of those emails I feel the beating heart of our shared humanity. I feel a sense of deepening obligation to work harder and push further. But most of all, I feel a gratitude that I cannot put into words, that I somehow got to be the person on the other end of those emails, the leader of a company that ignites imaginations and enriches lives in such profound ways it defies description. What an honor and a privilege it has been.
Today we announced that I’m taking the next step in my journey at Apple. Over the coming months I will be transitioning into a new role, leaving the CEO job behind in September and becoming Apple’s executive chairman. A new person will be stepping into what I know in my heart is the best job in the world. That leader is John Ternus, a brilliant engineer and thinker who has spent the past 25 years building the Apple products our users love so much, obsessed with every detail, focused on every possible way we can make something better, bolder, more beautiful, and more meaningful. He is the perfect person for the job.
John cares so much about who we are at Apple, what we do at Apple, who we reach at Apple, and he has the heart and character to lead with extraordinary integrity. I am so proud to call him Apple’s next CEO. This company will reach such incredible heights under his leadership, and you will feel his impact in every bit of delight and discovery that grows out of the products and services to come. I can’t wait for you to get to know him like I do.
This is not goodbye. But at this moment of transition, I wanted to take the opportunity to say thank you. Not on behalf of the company, this time, though there is a wellspring of gratitude for you that overflows inside our walls. But simply on behalf of me. Tim. A person who grew up in a rural place in a different time and, for these magical moments, got to be the CEO of the greatest company in the world. Thank you for the confidence and kindness you’ve shown me. Thank you for saying hi to me on the street and in our stores. Thank you for cheering alongside me when we unveiled a new product or service. Thank you, most of all, for believing in me to lead the company that has always put you at the center of our work. Every day we get up and think about what we can do to make your life a little bit better. And every day, you’ve made mine the best I could have asked for.
Thank you.
Tim Cook
Arthur Levinson, who has been Apple’s non-executive chairman for the past 15 years, will become its lead independent director on September 1, 2026. Ternus will join the board of directors, also effective September 1, 2026.
“Tim’s unprecedented and outstanding leadership has transformed Apple into the world’s best company. He’s introduced groundbreaking products and services time and again, and his integrity and values are infused into everything Apple does,” said Levinson. “On behalf of the entire board of directors, we are incredibly grateful for his countless contributions to Apple and the world, and we are thrilled he will now be executive chairman. We believe John is the best possible leader to succeed Tim and as he transitions to CEO we know his love of Apple, his leadership, deep technical knowledge, and relentless focus on creating great products will help lead Apple to an extraordinary future.”
“I want to thank Art for the incredible work he has done leading the board of directors for the past 15 years,” said Cook. “I have always found his advice to be invaluable and I appreciate his thoughtfulness and his unwavering dedication to the company. I am grateful he will serve as our lead independent director, and I look forward to working with him in my new role.”
Tim Cook joined Apple in 1998. He became CEO in 2011 and has overseen the introduction of numerous products and services, including new categories like Apple Watch, AirPods, and Apple Vision Pro, and services ranging from iCloud and Apple Pay to Apple TV and Apple Music. He was also instrumental in expanding existing product lines. Under Cook’s leadership Apple has grown from a market capitalization of approximately $350 billion to $4 trillion, representing a more than 1,000% increase, and yearly revenue has nearly quadrupled, from $108 billion in fiscal year 2011 to more than $416 billion in fiscal year 2025. The company has expanded its global footprint substantially, particularly in emerging markets; it is now in more than 200 countries and territories. Apple operates over 500 retail stores and has more than doubled the number of countries in which its customers can visit an Apple Store. During his tenure, Apple has grown by more than 100,000 team members and increased its active installed base to more than 2.5 billion devices.
Apple Services has been a major focus area of Cook’s, and during his tenure the category has grown to become a more than $100 billion business, the equivalent of a Fortune 40 company. Cook was also instrumental in creating the wearables category at Apple, which now includes the world’s most popular watch and headphones, and which has served as the foundation for Apple’s remarkable impact on the health and safety of its users. Under Cook’s leadership, Apple also transitioned to Apple-designed silicon, enabling the company to own more of its primary technology and deliver industry-leading gains in power efficiency and performance that directly benefit users across its products.
Cook has made Apple’s core values even more central to the company’s decision making and product development. Under his leadership, the company reduced its carbon footprint by more than 60 percent below 2015 levels during a period in which revenue nearly doubled. Cook, who has long advocated for privacy as a fundamental human right, has made privacy and security imperative at Apple, setting a standard for user protection that continues to set the company apart from the rest of the technology industry. He has also pushed for continued innovation in the accessibility space, believing that Apple products should be made for everyone. And he has made central to his leadership the notion that Apple should be a place where everyone can feel they belong and where everyone is treated with dignity and respect.
Ternus joined Apple’s product design team in 2001 and became a vice president of Hardware Engineering in 2013. He joined the executive team in 2021 as senior vice president of Hardware Engineering. Throughout his tenure at Apple, Ternus has overseen hardware engineering work on a variety of groundbreaking products across every category. He was instrumental in the introduction of multiple new product lines, including iPad and AirPods, as well as many generations of products across iPhone, Mac, and Apple Watch.
Ternus’s work on Mac has helped the category become more powerful and more popular globally than at any time in its 40-year history.
That includes the recent introduction of MacBook Neo, an all-new laptop that makes the Mac experience even more accessible to more people around the world. This past fall, his team’s efforts were on full display with the introduction of a redefined iPhone lineup, including the incredibly powerful iPhone 17 Pro and Pro Max, the radically thin and durable iPhone Air, and the iPhone 17, which has been an incredible upgrade for users. Under his leadership, his team also drove advancements in AirPods to make them the world’s best in-ear headphones, with unprecedented active noise cancellation, as well as the capability to become an all-in-one hearing health system that can serve as over-the-counter hearing aids.
Ternus led much of the company’s focus in areas like reliability and durability, introducing new techniques that have made Apple products remarkably resilient. He has also driven much of Apple’s innovation in materials and hardware design that have reduced the carbon footprint of its products, including the creation of a new, recycled aluminum compound that has been introduced across multiple product lines, the use of 3-D printed titanium in Apple Watch Ultra 3, and innovations in repairability that have increased the lifespans of several Apple products.
Prior to Apple, Ternus worked as a mechanical engineer at Virtual Research Systems. He holds a bachelor’s degree in Mechanical Engineering from the University of Pennsylvania.
