Mark Mahaney expects about 20% organic revenue growth in DoorDash's (DASH) earnings. He believes the company needs to continue delivery initiatives beyond food to distinguish itself from competitors like Uber Technologies (UBER) and Lyft Inc. (LYFT). As for DoorDash's future around AI, Mark thinks the company's focus on evolving tech offers an advantage that trumps long-term fears. Tom White offers an example options trade for DoorDash ahead of earnings.
