Rivian CFO Claire McDonough to Depart; Shares Fall in After-Hours Trading

Rivian Automotive (NASDAQ:RIVN) announced Thursday that Chief Financial Officer Claire McDonough will step down from her position, sending shares down in after-hours trading. The electric vehicle manufacturer stated her departure will be effective October 30, 2026.

Shares of Rivian fell 2.1% in extended trading following the news. The departure of a key executive, particularly one who guided the company through its public offering, can create uncertainty for investors regarding leadership stability and strategic continuity.

Leadership Transition Details

According to the company, McDonough is leaving to pursue a new opportunity and to relocate to the East Coast to be closer to her family. She will remain in her role for the next two months to facilitate a smooth transition of her responsibilities.

Rivian has appointed Derek Mulvey, the current Vice President of Finance, to serve as Interim Chief Financial Officer upon McDonough’s departure. Mulvey joined Rivian in 2021 from J.P. Morgan and has been involved in the company's financial planning, capital allocation, and investor relations. The company has initiated a comprehensive search for a permanent CFO, considering both internal and external candidates.
