Rivian is changing CFOs. Claire McDonough is leaving the company, her final day is October 30, 2026, and Derek Mulvey, currently Vice President of Finance, is expected to step in as Interim Chief Financial Officer the moment she walks out the door.
The reason is about as normal as these things get. McDonough is taking a new opportunity and relocating to the East Coast to be closer to family. She is staying on for roughly two months to hand off strategic initiatives directly to RJ Scaringe and the rest of the executive team, which is a real transition window rather than the abrupt exits we sometimes see in this industry. Rivian says an executive search is already running and that it is looking at both internal and external candidates.
McDonough has been at Rivian since January 2021, which means she has been there for essentially the entire public company era. She ran point on the $13.7 billion IPO in November 2021, one of the biggest in US history, and that raise is what funded the Normal plant ramp that got R1 out the door in the first place. Since then her team built the capital frameworks, pushed the cost reduction work aimed at getting gross margins positive, and helped structure the partnership deals that kept the balance sheet healthy through some genuinely rough quarters.
Her replacement, at least for now, is not a stranger. Mulvey joined Rivian in 2021 as well and has worked alongside Scaringe and McDonough on financial planning, capital allocation, strategic partnerships, and investor relations. Before Rivian he was a VP at J.P. Morgan. So the interim handoff goes to someone who already knows where every dollar is committed, which matters more than it sounds.
Uh oh, what does she know?
She knows that Rivian’s financials are improving every quarter, with plenty of cash on hand to get them through. Rivian is in way better shape now than any of the previous years she could have jumped ship and didn’t. So it’s a sign that she is confident Rivian has reached a point where it can succeed with or without her.
And/or it’s a neutral sign, and she really is doing it to be closer to family on the east coast.
