Billionaire Bill Ackman Has Been All-In on Uber. Is Now the Time to Buy the Stock?

Uber reported Q3 revenue of $14.77 billion, up 10% year over year and ahead of the $14.69 billion consensus; gross bookings rose 20%, adjusted EBITDA increased 31% to $3 billion, and adjusted EPS climbed 35% to $0.88. The company forecast constant-currency gross bookings growth of 18%–22% and adjusted EPS growth of 34%–39%; it expects 700 autonomous vehicles on its platform by year-end and more than 2,000 by the end of 2027. The article views Uber’s operating leverage and partner role in autonomous driving positively, while noting that the long-term impact of autonomous vehicles remains uncertain and the stock is down around 25% over the past year.

Analysis

The investable question is not whether Uber can keep growing bookings, but who captures the economics as labor rules and autonomy change the marketplace. Reclassification can make reported mobility revenue look weaker without equivalent demand deterioration, yet it may also signal higher driver costs or less pricing flexibility; track contribution profit and driver supply, not bookings alone. If autonomous-vehicle operators rely on Uber for demand aggregation, Uber retains customer access but may face tougher take-rate bargaining as fleet owners gain alternatives. The stated rollout is too small to establish near-term earnings materiality; the 6–18 month risk is that partner economics, rather than adoption, disappoint. Delivery and grocery diversify the growth engine, but rising order volume is only valuable if fulfillment costs and promotions do not absorb the incremental margin. Costco’s partnership is a potential channel benefit, not enough evidence by itself to change a Costco earnings view.

Near term, operating leverage supports the bull case, but the cited forward multiple depends on 2027 estimates and should not be treated as a floor. There are source-quality issues to verify before sizing: the article mixes Q2 and Q3 operating data and gives an internally inconsistent adjusted-EPS guidance range. The consensus may be underweighting platform resilience, but the article’s optimistic AV-partner assumption is not yet proven. A sustained deterioration in mobility contribution profit, driver availability, or forward guidance would undermine the thesis.

Key Decisions for Investors

• Consider a staged long in UBER rather than chasing a single-day reaction; the thesis is earnings conversion and marketplace scale, not a near-term AV earnings windfall. Reassess after confirming the correct quarter and guidance from the company filing.
• For the next 1–3 months, monitor mobility contribution economics alongside gross bookings, driver supply in constrained markets, and any evidence that labor classification is raising costs rather than merely changing reported revenue. A bookings-growth slowdown paired with weaker contribution profit falsifies the operating-leverage case.
• Over 6–18 months, treat AV announcements as partnership-economics catalysts, not just vehicle-count catalysts. Watch whether Uber retains customer access and attractive economics versus fleet operators building direct channels; reduce exposure if partner terms or take rates visibly weaken.
• No actionable COST trade from the partnership mention alone: verify whether the relationship produces material incremental sales or changes fulfillment economics before attributing an earnings impact.
