John Ternus officially became Apple’s CEO on September 1, 2026, succeeding Tim Cook, who led the company for 15 years and remains as executive chairman [1, 2, 3, 4, 5, 6]. At 51 years old, Ternus is the third CEO of Apple since 1997 and was previously senior vice president of hardware engineering [1, 7, 5].
Under Cook’s leadership, Apple’s market value grew to approximately $4.6–4.7 trillion, with iPhone sales exceeding 3.1 billion units [1, 2, 3]. Despite this success, Apple faces major challenges integrating AI technology and is considered behind competitors in AI capabilities [1, 8, 2, 7, 6]. Key AI talent has left for rivals like Meta, and Apple has delayed an overhaul of its Siri assistant, now embedding Google’s Gemini AI technology [6].
Ternus is credited for deep hardware engineering expertise and is expected to intertwine AI advancement with hardware development, while maintaining Cook’s supply chain approach [7, 3, 5, 9]. Analysts note that while AI will dominate the industry’s future, consumer demand still centers on hardware. Carolina Milanesi of Creative Strategies said, "Consumers are still buying hardware first, and it’s going to be like that for a long time. You’re not going to discover the value of AI if you’re not interested in the hardware" [7].
IDC’s Francisco Jeronimo called Apple’s upcoming September 9 event "quite an important milestone for the company around foldables and around innovation," adding, "It's becoming clear that AI is not a fad... it's something that will dictate the future of most tech companies" [1]. Ternus sent his first internal memo teasing a "huge launch next week" referring to the event [10, 9]. The event is expected to introduce Apple’s first foldable iPhone and an upgraded AI-powered Siri [1, 8, 7, 5, 10, 9, 6]. The foldable iPhone market is projected to reach 17 million units shipped and 40% share by the end of 2027 [5].
Tim Cook praised his successor, saying, "Few people understand what it takes to build products that change the world the way John does" [9]. Dan Ives of Yorkville Ives & Co. noted, "Tim Cook left the house in phenomenal order. But now, it's about Ternus defining the AI chapter" [7].
Ternus’s public debut as CEO will take place at the Apple product launch on September 9, where the company plans to reveal its latest innovations and set a path for AI integration alongside hardware advances [1, 8, 7, 5, 10, 9, 6].
