Tim Cook completes his final day as chief executive officer of Apple on Monday, handing control of the four-trillion-dollar technology giant to John Ternus.
Cook, 65, steps down 15 years after taking over executive leadership following the death of Apple co-founder Steve Jobs. Under Cook's tenure, Apple transformed into the most valuable company in the world, achieving a market valuation of $4 trillion (€3.4 trillion).
Starting Tuesday, September 1, 2026, John Ternus will officially take charge of the technology company. The 51-year-old executive currently serves as Apple's senior vice president of Hardware Engineering and will become the third chief executive officer in the company's history, following Jobs and Cook.
Cook will remain involved with the company as he transitions to become chairman of Apple's Board of Directors.
Cook originally joined Apple in 1998 as senior vice president for worldwide operations before being appointed chief operating officer. Following the passing of Jobs in October 2011, Cook assumed the chief executive role, overseeing the launch of new product lines such as the Apple Watch and AirPods while expanding Apple's subscription services and worldwide retail presence.
Hardware Focus and Artificial Intelligence Strategy
The selection of an executive with a background in hardware engineering to lead the company indicates that Apple believes the future of artificial intelligence will center on integrated physical devices rather than relying solely on cloud services. Apple envisions artificial intelligence capabilities embedded directly into hardware such as smart glasses or AirPods equipped with built-in cameras.
The leadership transition occurs as Apple faces scrutiny for lagging behind established rivals and specialized artificial intelligence developers. Tech competitors like Google have already integrated advanced artificial intelligence tools directly into their mobile hardware and Android operating system, while emerging companies such as OpenAI, the creator of ChatGPT, and Anthropic, the developer of Claude, have established leadership positions across the sector.
OpenAI and Anthropic have pioneered generative artificial intelligence applications that process text, image, and voice inputs. Meanwhile, major technology platforms have raced to embed these capabilities into consumer software, creating intense pressure on device manufacturers to deliver intuitive, hardware-level artificial intelligence features.
Financially, Apple continues to demonstrate extraordinary scale, having recently reported a 17 percent increase in half-year profits to $72 billion. The company also temporarily dethroned Nvidia as the most valuable publicly traded company in the world.
Tariffs and Supply Chain Challenges
In addition to shaping Apple's artificial intelligence roadmap, the incoming chief executive officer will need to manage ongoing economic headwinds and trade issues in the United States. Ternus takes the helm as Apple navigates the impact of U.S. tariff policies imposed by President Trump, which affect imported components and international manufacturing pipelines.
To address domestic trade demands, Apple promised to invest tens of billions of dollars within the United States. The company pledged to source U.S.-manufactured semiconductor chips for iPhones and announced plans to add a Mac Mini assembly line in Texas.
Despite those commitments to domestic production, the vast majority of Apple's manufacturing infrastructure and component supply chains remain situated in Asia. Balancing supply chain vulnerabilities with domestic political pressures will represent a central challenge for Ternus.
Global technology companies rely heavily on Asian manufacturing ecosystems, particularly in Taiwan and mainland China, where complex component assembly and advanced chip fabrication facilities are concentrated. Transitioning significant portions of manufacturing to domestic locations involves substantial capital investments and long development timelines.
European Taxation and Digital Regulations
The executive transition also coincides with ongoing financial and regulatory matters across Europe. Information disclosed last week revealed that Apple paid more than €14.5 billion ($14.5 billion) in taxes to Ireland during its most recent fiscal year.
The tax payment accounts for approximately 40 percent of Ireland's total tax revenues for the fiscal year, underscoring the massive economic impact of Apple's European financial operations on Irish state revenue.
At the same time, Apple faces strict oversight from European regulatory bodies. An European Union court confirmed that Apple must comply with digital market rules, reinforcing legislative frameworks aimed at regulating tech platforms operating within member states.
The European Union Digital Markets Act sets out strict obligations for large technology companies designated as market gatekeepers. These rules require platforms to enable fair market competition, support interoperability across software services, and provide consumers with greater choice regarding default applications and app stores.
