Apple promoted its hardware chief, Dan Riccio, to one newrole “Focusing on a new project.” He reports to CEO Tim Cook, Apple announced Monday.

Riccio was previously the company’s senior vice president of hardware engineering, responsible for the physical aspects and electrical engineering of Apple products, including iPhones. He has been on Apple’s executive team since 2012 and reports to Cook.

Apple did not specify in its announcement which project Riccio would be working on.

“Then I look forward to doing what I love most: putting all my time and energy at Apple into creating something new and wonderful that I can’t be more excited about,” Riccio said in a statement.

John Ternus takes over from Riccio. Ternus was previously VP at Apple, and his public profile has grown in recent years. Last year, he was a key presenter of the company’s transition from Intel processors to its own M1 laptop processors at a live stream launch event.
