John Ternus is replacing Tim Cook as CEO after 15 years with Cook at the helm. Bloomberg’s Mark Gurman expects a leadership shakeup to follow soon. According to Gurman, much of Apple’s leadership, apart from the recently replaced CFO and COO, are nearing retirement, and it will fall on Ternus to replace them within the next three years.
The executives expected to be replaced include Johnny Srouji, Deirdre O’Brien, Luca Maestri and Greg Joswiak. Srouji, Apple’s senior vice president of Hardware Technologies, has reportedly revolutionized the company’s chip division, commonly known as Apple Silicon. He was also instrumental in integrating Apple’s chips with its broader hardware divisions as the company ended its reliance on Intel. Gurman says combining engineering and technology leadership under a single executive is something that will likely disappear with Srouji’s departure.

O’Brien, who joined the company in 1988, heads Apple’s retail arm while also serving as its vice president of People. She reportedly possesses significant institutional knowledge and helped guide the company through the COVID-19 pandemic.
Maestri is Apple’s recently replaced former CFO, but he is currently working as the company’s “vice president of Corporate Services.” This means he is still overseeing responsibilities that the current CFO, Kevan Parekh, apparently isn’t ready to take on yet.
Joswiak joined Apple in 1986, working on the early Macintosh computers, and has played a key role in the company’s marketing. According to Gurman, he has a right-hand man named Bob Borchers, but Borchers is also eyeing retirement. Gurman says Apple is looking at “newly appointed head of artificial intelligence marketing Lilian Rincon and longtime iPhone marketing chief Kaiann Drance” as potential replacements.

Cook, who succeeded Apple co-founder Steve Jobs in 2011, leaves behind one of the most significant transformations in the history of corporate technology. Under his leadership, Apple expanded from a company valued at roughly $350 billion when he became CEO into one of the world’s most valuable technology companies, reaching multi-trillion-dollar valuations. Ternus will officially take over as CEO on Sept. 1.
Ternus enters the CEO role with a background closely tied to Apple’s products. He joined Apple in 2001 and has held senior hardware responsibilities across products including the iPad, Mac, AirPods and iPhone. He became senior vice president of Hardware Engineering in 2021.
The transition comes soon after Apple unveiled upgraded Mac mini and Mac Studio computers powered by newer chips designed to handle increasingly demanding AI workloads. Ternus is inheriting a company with significant financial strength and a loyal customer base, but also faces challenging questions about its progress in artificial intelligence.
