Starwood interim CEO Adam Aron has stepped down to take up the chief executive position at cinema chain AMC.
The move comes just weeks after Marriott International agreed to buy Starwood in a $12.2 billion deal to form the world’s largest hotel company.
Aron became acting CEO after the departure of former CEO Frits van Paasschen in February.
Starwood’s chief financial officer Thomas B. Mangas will take over as CEO on December 31.
"I would like to thank Adam for stepping in to lead our company during a pivotal time in Starwood’s history. He accomplished much during his tenure as CEO, and contributed in countless ways as a member of our Board for nearly a decade," said Starwood chairman Bruce W. Duncan.
"He leaves the company in excellent hands with Tom, a valued leader on our team who was instrumental in our review of our strategic alternatives and will continue to oversee the completion of our combination with Marriott."
Before Starwood, Aron was chairman of Vail Resorts, Inc. and president at Norwegian Cruise Line.
Marriott’s acquisition of Starwood is expected to complete in mid-2016.
