Tim Cook to Step Down as Apple CEO, John Ternus Ascends
This week, Tim Cook announced he would resign as CEO of Apple after a remarkable 15-year tenure. His successor, long-serving Apple executive John Ternus, is slated to take on the CEO role starting September 1.
Cook’s decision follows a noteworthy trend among top executives, as a surge in CEO transitions has been observed across various industries. According to consultancy Russell Reynolds, the first quarter of 2026 witnessed a record 77 new CEO appointments within the 13 indices tracked by the firm, including the S&P 500, FTSE 100, and Germany’s DAX 40. This number represents the highest total seen in the first quarter since at least 2018, with CEO departures also reaching unprecedented levels in 2025.
Interestingly, the average tenure of outgoing CEOs in the United States has risen significantly over the past year, jumping from 8.3 years to 11.8 years. This trend is particularly relevant as Cook’s departure signals the end of an era at the helm of one of the world’s most valuable companies.
Noteworthy exits among seasoned CEOs this year include Doug McMillon from Walmart, who led the company as CEO since 2014, and Warren Buffett, who has been at the forefront of Berkshire Hathaway since 1970. Additionally, several high-profile leadership transitions have occurred recently, including Josh D’Amaro replacing Bob Iger at Disney and Michael Fiddelke succeeding Brian Cornell at Target.
The dynamics behind CEO transitions often reflect a myriad of personal and organisational factors. On a broader scale, the corporate landscape is undergoing significant transformations. The rise of artificial intelligence, coupled with a changing labour market that is reshaping employee expectations—including benefits such as parental leave—demands a fresh approach from company leaders. There are voices advocating for potentially drastic staff reductions in various white-collar roles, presenting challenges that many departing executives may prefer to pass on to their successors.
As companies continue to navigate the complexities of a post-financial crisis environment, alongside fluctuations due to the COVID-19 pandemic and elevated inflation rates, it is understandable that some leaders might choose to step aside, leaving these formidable challenges to the next generation of executives.
