Rivian's Top Finance Executive Steps Down During Crucial Production Push

Rivian's chief financial officer, Claire McDonough, will leave at the end of October 2026, the company told regulators on August 27. Finance VP Derek Mulvey will fill the role temporarily. The change comes as Rivian increases output of its new R2 SUV, which started reaching customers in summer 2026. No timeline for a permanent replacement has been shared.
