Stock price when the opinion was issued
Has grown cashflows, very encouraging. Taking share from LYFT. Over several years stock's been volatile, but hasn't done that much due to looming robotaxis and autonomous vehicles. If that picks up steam, competitive dynamics change; UBER would move from handling both supply and demand, to being just one of many suppliers chasing demand.
Multiple's come down, showing good fundamentals. Watch the space. Waymo has no experience in the space, whereas Uber's really well positioned. That partnership will work well at first, but it's the future he's concerned about.
He sold some shares a few weeks ago. Good news is that robo-taxis won't happen for a while. Bad news is that robo will cost somebody more, and he can't figure out the economics, but will slow down growth.
