John Ternus has stepped in as the new CEO of Apple , taking over a company that reached a $4.6 trillion market cap under Tim Cook. During Tim Cook’s 15 years as CEO, Apple’s market cap grew significantly, though the area where Cook was less successful was in making Apple a top AI company.
As Ternus takes the helm, mathematical advantages such as a low P/E ratio no longer apply, and the company faces the law of large numbers. While Cook’s business successes increased the company’s value more than 13-fold from a $350 billion market cap, further growth of that magnitude is constrained by Apple’s current size.
Leadership Style and Engineering Focus
Ternus brings a background in hardware engineering and joined Apple’s product design group in 2001. Unlike Cook, who was heavily involved in operations and the supply chain, Ternus is working to bring products to the fore by focusing heavily on engineering and design. He has delegated some duties usually handled by the CEO to other executives to spend more time on the engineering side of the business, speaking regularly with Apple’s design team and making multiple visits to the studio in a day.

During a recent interview with TIME, Ternus discussed his involvement with design teams, emphasizing that software and hardware designers understand engineering, and engineers have a deep appreciation for design. Bloomberg reported that Ternus spends more time working with industrial design and human interface teams while finance and supply-chain colleagues handle a greater proportion of that work.
Artificial Intelligence and Future Growth
Ternus now plans an engineering-focused overhaul to integrate AI into products and emphasize personalized experiences.
Transition to a Product-Oriented Period
Apple may be in a transition from a primarily execution phase to a more product and design-oriented period, returning to an era of creativity after a period of exponential growth under Tim Cook. While investors should expect Apple to hit new market cap records in the coming years, the stock is unlikely to match the rapid growth seen under Cook, making Ternus’s success heavily dependent on Apple’s AI-related achievements and future product execution.
