Nikesh Arora, CEO of Palo Alto Networks and former SoftBank executive, is joining Uber’s board of directors, according to a Wednesday regulatory filing. His appointment comes during a broader leadership shakeup that includes the departure of head of delivery Pierre-Dimitri Gore-Coty and the promotion of Andrew Macdonald to president and COO. Arora said he is honored to join Uber’s board as it advances autonomous mobility and transforms urban transportation. Uber CEO Dara Khosrowshahi praised Arora as a “strategic and disciplined operator,” as Uber sharpens its focus on autonomous mobility amid growing competition from Tesla and Waymo in the robotaxi space.
