(Reuters) – AutoNation Inc (NYSE:AN) named Thomas Szlosek as its chief financial officer, effective on or about Aug. 7, the auto retailer said on Tuesday.

Szlosek will move from medical product maker Avantor (NYSE:AVTR) Inc, where he is currently finance chief.

AutoNation’s current CFO Joe Lower will transition to a newly created role where he will oversee all business transformation initiatives.

“I now have the opportunity to take a leading role in many of our business transformation projects,” Lower said.

In its most recent quarter, the car retailer missed Wall Street estimates as higher new vehicle and after-sales demand was offset by weakness in used vehicle and customer financial service businesses.
