McDonough will transition to GE Vernova to assume the CFO position, citing a desire to move to the East Coast and be nearer to her family. The executive announced the career move through a post on LinkedIn.

The company emphasized that her departure is “not the result of any disagreement” and noted she will continue in her current capacity for the following two months to ensure a seamless handoff.

Derek Mulvey, who currently serves as Rivian’s VP of Finance, has been tapped to assume the interim CFO position when McDonough departs. Mulvey came aboard in 2021 and has overseen financial planning, strategic partnerships, capital allocation, and investor relations functions. Prior to Rivian, he held a vice president position at J.P. Morgan.

The automaker has commenced a comprehensive search process for a permanent CFO, evaluating both internal talent and external candidates.

McDonough’s Impact at Rivian

McDonough came to Rivian in January 2021, taking the CFO position during a critical period for the privately-held electric vehicle manufacturer. She succeeded Ryan Green as the company was consuming significant capital while working to bring three vehicle models to production.

During her initial year, she orchestrated one of the largest initial public offerings in United States history, securing $13.7 billion in November 2021. The shares launched at $78. By Thursday’s market close, the stock traded at $16.80.

In addition to the public listing, she collaborated extensively with CEO RJ Scaringe and the engineering divisions to control vehicle production expenses. This proved challenging for a company losing money on each unit manufactured.

She was instrumental in structuring the Volkswagen partnership agreement, which reached completion in November 2024. The arrangement calls for VW to contribute up to $5.8 billion to Rivian through 2027 in return for access to the company’s electrical architecture and software platforms.

Rivian’s Path Forward

Her departure comes as the company navigates a critical phase. Rivian is presently ramping up manufacturing and customer deliveries of its R2 SUV, which began reaching buyers this summer.

CEO RJ Scaringe commended McDonough’s contributions, noting she steered the organization through its public debut and established the financial infrastructure that supports current operations. He also voiced strong support for Mulvey’s appointment to the interim position.

RIVN stock had gained 2.88% during Thursday’s standard trading session before reversing with the after-hours decline triggered by the CFO announcement.
