Apple CEO John Ternus shares first memo to staff in new role

John Ternus spent his first day as Apple's chief executive doing what most office workers do: sending out emails.

According to Bloomberg 's Mark Gurman , who obtained the note, Ternus sent a staff-wide memo to preview what he called a standout showing at next week's iPhone event and to publicly thank Tim Cook, who spent 15 years at Apple's helm.

Ternus, who previously ran Apple's hardware engineering organization, told staff he's looking forward to what comes after the September 9 launch just as much as the event itself.

Gurman reported that Ternus called the coming iPhone reveal "phenomenal" in the memo, a preview that lines up with Apple's plans to introduce its first foldable iPhone and push further into smart home hardware, according to Bloomberg's reporting.

The memo also included a tribute to Cook, who is staying on at Apple as executive chairman rather than leaving the company outright.

Ternus credited his predecessor with sharing his knowledge throughout the transition and framed Cook's tenure as one defined by strong values, according to Bloomberg.

Tuesday also marked Ternus's debut on X , where he joins Cook and marketing chief Greg Joswiak as the company's most visible executives on the platform.

Per Gurman's reporting, Joswiak indicated that Ternus will have more to share when he takes the stage at next week's "Surprise and Shine" event.

Cook, for his part, sent his own farewell note to staff a day earlier, telling employees he'll miss the daily work but is confident in the direction Ternus will take the company.

Ternus's promotion caps a long climb inside Apple.

As we've detailed in an explainer of the incoming CEO , Ternus joined Apple in 2001 after a brief stint as a mechanical engineer, working his way from the product design team to VP of hardware engineering in 2013 and senior VP in 2021.

Apple has credited him with hardware wins, including the iPhone Air and the MacBook Neo, as well as a pivotal role in the company's shift to using in-house Apple silicon.
