Rivian Automotive, Inc. announced that Chief Financial Officer Claire McDonough will resign effective October 30, 2026, to pursue a new opportunity and relocate to the East Coast. The company confirmed that her departure is amicable and involves no disagreements regarding financial reporting, internal controls, operations, or corporate policies. McDonough will remain in her current role through late October to facilitate an orderly transition. To maintain continuity in capital planning and execution, Derek Mulvey, Rivian's Vice President of Finance since 2021, is expected to step in as Interim CFO while the board conducts a comprehensive internal and external search for a permanent successor.
A CFO transition is a material governance and financial management event for a capital-intensive EV manufacturer, though the extended handover window and internal interim appointment mitigate immediate operational disruption.
