Tim Cook has concluded his tenure as Apple's CEO. According to Apple's previous announcement, John Ternus, who has been in charge of hardware engineering for a long time, will officially take over on September 1st, while Cook will assume the role of Executive Chairman and continue to remain with the company.

A 15-year tenure comes to an end

On the day of his departure, Cook sent an internal letter to the employees, thanking the team for their work over the past years and expressing his support for the new CEO. Apple announced this transition as early as April of this year, so the overall arrangement was relatively smooth.

Since Cook took over in 2011, Apple's business scale and performance on the capital market have significantly expanded. Reports mention that Apple's current valuation is close to $5 trillion, with over 2.5 billion active devices in use, and its revenue is also at a historical high.

Apple has evolved from a hardware company to an ecosystem platform.

During Cook's tenure, Apple did not replicate a single blockbuster narrative at the iPhone level; instead, it continued to expand its product and service ecosystem. Apple Watch, AirPods, subscription services, payment business, and self-developed chips have constituted the main pillars of Apple's growth in recent years.

At the same time, Apple's profitability and supply chain efficiency also continued to improve during this period. As a result, what Cook left behind was not just the performance of a single product, but a more comprehensive software and hardware ecosystem as well as a global operations system.

• The number of active device installations exceeds 2.5 billion.
• The company is valued at nearly $5 trillion.
• The new CEO will officially take office on September 1st.

The new management team is first faced with the pressure of AI.

However, this transition does not mean that Apple has entered a period of ease. Reports suggest that the most immediate pressure for Ternus after taking over comes from artificial intelligence. Although Apple has demonstrated new versions of Siri and Apple Intelligence features on WWDC26, the market continues to question its progress in the field of generative AI.

This also affects the focus of investors on the replacement of Apple's management team. Ternus has been in charge of hardware for a long time, and the outside world will observe whether Apple will place more emphasis on product execution and the implementation of AI during the new product cycle.

The September product launch event becomes the first observation window

The timing also makes this handover more noteworthy. Apple's next major product launch is scheduled for September 9th, just 8 days after Tim Cook officially takes on the role of CEO. The outside world expects that at that time, Apple will release a new generation of iPhone, which will also mark the first significant public product cycle since his appointment.

For Apple, its vast user base remains its greatest advantage. However, against the backdrop of accelerating competition in AI, how to transform this existing user base into growth for the next phase will be the first challenge that the new management team faces.
