Tim Cook Steps Down as Apple CEO After Historic 15-Year Run

Tim Cook is officially stepping down as Apple Chief Executive Officer to become Executive Chairman of the Board of Directors, marking the end of a historic 15-year tenure that reshaped the global tech industry. Longtime hardware engineering chief John Ternus will take over as the new CEO. Cook took charge in August 2011 after Steve Jobs stepped down due to failing health, facing widespread skepticism about whether the company could thrive without its iconic co-founder.

Under Cook's leadership, Apple delivered unprecedented financial growth, expanding from a valuation of approximately 350 billion dollars into a massive enterprise that touched a 5 trillion dollar market capitalization. This marked an extraordinary 14-fold rise in market value and delivered a stock return of more than 2,000 percent, generating tens of millions of dollars in shareholder value every single hour of his tenure. Annual revenue quadrupled from around 108 billion dollars to over 400 billion dollars, supported by massive stock buyback programs totaling nearly 880 billion dollars.

Cook achieved this transformation by building a world-class global supply chain and expanding Apple far beyond the original iPhone. He launched major hardware hits including the Apple Watch, AirPods, and custom Apple Silicon processors, while pioneering spatial computing with Apple Vision Pro. Crucially, he turned digital services like the App Store, iCloud, Apple Pay, and Apple Music into a dedicated 100 billion dollar annual powerhouse, establishing an active base of more than 2.5 billion devices worldwide.

In his new role as Executive Chairman, Cook will continue providing strategic guidance, supporting the incoming leadership, and overseeing relations with global governments and policymakers. New CEO John Ternus takes charge of day-to-day operations at a pivotal time, with responsibilities to guide the company through the ongoing artificial intelligence revolution, manage global supply chain costs, and direct Apple's upcoming hardware roadmap.
