Tim Cook to Step Down After $4 Trillion Apple Run
CNBC reports that Tim Cook is handing over the role of Apple CEO to longtime hardware executive John Ternus, with Cook’s tenure set to end on Sept. 1. Under Cook’s 15-year leadership Apple’s market capitalization rose from about $350 billion to $4 trillion, revenue nearly quadrupled to more than $400 billion, and the company built a services business that generated $109.2 billion in fiscal 2025. The article credits Cook’s operational and supply‑chain skills — including diversification into India and Vietnam and recent U.S. manufacturing expansions — for Apple’s value creation. It also notes challenges: wearables revenue declined in fiscal 2025 and the Vision Pro has not become a mainstream consumer product. The piece highlights Apple’s large installed base (2.5 billion active devices) and recent U.S. manufacturing partnerships announced in March.
Executive succession at Apple — a major platform owner with large services, App Store and advertising exposure — can influence platform policy, App Store economics, ad monetization and supply-chain strategy; Cook’s tenure produced large financial and structural shifts relevant across tech and marketing ecosystems.

Tim Cook to Step Down; John Ternus to Become CEO
In a town hall following the announcement that John Ternus will become Apple CEO on September 1, Tim Cook discussed his tenure and cited major product missteps and successes. Cook called the 2012 launch of Apple Maps a major mistake that led to customer frustration and internal consequences, including Scott Forstall's departure, and said he personally apologized to users. He also mentioned two other high-profile failures — the unreleased AirPower charging mat and the never‑presented self‑driving car project — while highlighting the Apple Watch, Apple Pay, AirPods and Apple’s shift to in‑house processors as key achievements. The remarks were reported by Bloomberg and took place amid the planned leadership transition that will move Cook to the board chair role.
Tim Cook’s Final Earnings Call as Apple CEO
Tim Cook’s final earnings call as Apple CEO coincides with Apple reaching a $5 trillion market cap and surpassing Nvidia, even as the company faces a global memory shortage that has forced device price increases. John Ternus will take over as CEO on Sept. 1. Apple has raised iPad and Mac prices and announced an iPhone leasing program with Klarna starting at $17.99/month. Investors and analysts are watching how higher prices will affect demand, Apple’s capital spending (just over $11 billion forecast, $3.4 billion last quarter), and its AI strategy, which relies on licensing technology from Google after a frayed partnership and a July 10 lawsuit with OpenAI alleging trade-secret theft.
Apple names John Ternus CEO; Tim Cook becomes chairman
Apple announced that Tim Cook will step down as CEO and become executive chairman, effective September 1, 2026. Senior Vice President of Hardware Engineering John Ternus, 51, will succeed Cook as CEO and join Apple’s board on that date. Arthur Levinson, who has been Apple’s non‑executive chairman for 15 years, will become lead independent director effective September 1. The announcement highlights Cook’s 15‑year tenure as CEO during which Apple grew into a roughly $4 trillion company and expanded Services to more than $100 billion in annual revenue. The coverage provides biographical context for Ternus — a long‑time Apple engineer who joined in 2001 and rose through hardware design roles — and notes his involvement in iPad, AirPods, iPhone, Mac and Apple Watch product lines as well as his focus on durability, repairability and recycled materials. The change concludes a widely anticipated leadership transition at one of the world’s largest technology platforms.
