Stellantis appointed Joao Laranjo as its new chief financial officer, succeeding Doug Ostermann, who has resigned for personal reasons, the company said Monday. The Jeep-maker said Laranjo’s appointment is effective immediately. Laranjo joined Fiat Chrysler Automobiles—the automotive group formed by the merger of Fiat and Chrysler—in 2009 as chief accounting officer for Latin America, rising to chief financial officer for the region.
