(David Paul Morris/Bloomberg)Key Takeaways: Uber said Q3 bookings will be $58.25 billion to $60.25 billion, matching estimates as stronger competition in Brazil slowed trips growth. The outlook intensified investor concerns about Uber’s growth prospects in the robotaxi era despite second-quarter gross bookings of $58 billion topping expectations. The company blamed currency headwinds, which it said shaved off roughly one percentage point from reported growth for the gross bookings guidance. The company said the moderation in trips growth was “entirely attributable to Brazil,” its highest-volume market globally. Delivery rival DoorDash Inc. is scheduled to release earnings Aug. 5, while Lyft Inc. and Instacart will report on Aug. 6.
