Tim Cook has stepped down as chief executive of Apple after 15 years, handing the leadership of the $4.5 trillion technology giant to John Ternus.
The transition marks the end of one of the most successful corporate tenures in history. Cook, who took over from Steve Jobs in 2011, leaves behind a company that has evolved from a hardware manufacturer into a global services and ecosystem powerhouse.
John Ternus, the company’s longtime hardware engineering chief, will assume the role of CEO. The appointment signals a potential shift in focus back toward the core hardware innovation that defined Apple’s early years.
Under Cook’s leadership, Apple’s market valuation grew from approximately $350 billion to its current $4.5 trillion mark. This growth was driven by the expansion of the iPhone lineup and the successful launch of the Apple Watch and AirPods.
The company also diversified its revenue streams through the Apple Services division, which includes the App Store, iCloud, and Apple Music. This pivot reduced the company’s absolute dependence on single-product cycles.
However, the transition comes at a time when the company is facing increasing scrutiny over its global footprint and the ethics of its supply chain, particularly regarding its relationship with the African continent.
Resource Reliance Versus Continental Investment
Apple’s global operations rely heavily on critical minerals sourced from Africa, yet the company has maintained a comparatively limited commercial presence on the continent.
The company utilizes vast quantities of cobalt, tantalum, and gold, much of which originates from the Democratic Republic of Congo (DRC). These minerals are essential for the production of lithium-ion batteries and capacitors used in every iPhone and MacBook.
While Apple has implemented strict auditing processes to ensure its supply chain standards are met, critics argue that the economic benefits of this mineral extraction rarely reach the local populations in the mining regions.
Unlike other global tech giants that have established regional hubs or significant R&D centres in Africa, Apple has lacked a substantial physical retail or corporate infrastructure in the region. The company primarily relies on third-party distributors to reach African consumers.
This imbalance between resource extraction and economic investment has become a point of contention for African policymakers who are seeking more equitable trade partnerships with Silicon Valley.
Market analysts suggest that John Ternus may face pressure to rethink Apple’s approach to emerging markets. As smartphone saturation peaks in North America and Europe, Africa represents one of the few remaining frontiers for significant user growth.
Ternus is known for his technical precision and deep understanding of the hardware lifecycle. His tenure as hardware chief saw the refinement of Apple’s silicon transition, which gave the company greater control over its components.
Investors are now watching to see if the new CEO will pursue a more aggressive expansion strategy in Africa and other emerging economies to sustain the company’s growth trajectory.
The shift in leadership also comes amid ongoing regulatory challenges in the European Union and the United States. Apple continues to battle antitrust lawsuits regarding the App Store’s commission structures and the “walled garden” ecosystem.
The World Bank has frequently highlighted the need for technology companies to invest in digital infrastructure across Africa to bridge the digital divide, a goal that aligns with the potential expansion of Apple’s services.
Tim Cook is expected to remain available to the board in an advisory capacity for a transition period. The company has not yet announced a successor for the hardware chief role previously held by Ternus.
The Apple board of directors will hold a formal investor call next week to outline the strategic priorities for the new leadership team.
