Rivian Automotive said CFO Claire McDonough will step down effective Oct. 30 to become CFO of GE Vernova, while Senior Vice President of Finance Derek Mulvey is expected to serve as interim CFO. Heidrick & Struggles is managing the search for a permanent replacement. Rivian shares fell 3.55% to $15.49 on Tuesday, as investors weighed the leadership transition alongside production targets, margin improvement and competition in premium electric vehicles. The company’s second-quarter automotive revenue rose 23% year over year to $1.15 billion, and management reiterated full-year delivery guidance of 65,000 to 70,000 vehicles, with production weighted toward the second half. Rivian is also preparing its mid-size R2 SUV, described in the new update as a sub-$45,000 vehicle slated for release in spring 2027, while expanding its technology and capital partnership with Volkswagen. Existing reporting separately said McDonough would join GE Vernova in November and become CFO on Jan. 1, 2027, succeeding retiring CFO Kenneth Parks, who would remain as an adviser; the differing timelines have not been reconciled in the supplied material.
